Implement the present invention and there is following beneficial effect: the present invention utilizes coordinating of locking shell fragment and the locking portion of turning collar inner surface, be in turning collar rotation process, to force locking shell fragment to produce deformation, locking shell fragment reaches locking object for recovering the power of deformation generation and turning collar direction of rotation, can in luminous intensity distribution adjustment process, effectively prevent because vibration, that sharply motion etc. brings is loosening and cause luminous intensity distribution shakiness problem.And adopt after above-mentioned locking device, the luminous intensity distribution degree of accuracy meeting of light fixture is higher, has solved the luminous intensity distribution misalignment problem that light fixture causes because of vibrations.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the assembling schematic diagram that in the present invention, flashlight luminous intensity distribution regulates locking device preferred embodiment;
Fig. 2 is the structural representation that in the present invention, flashlight luminous intensity distribution regulates locking device preferred embodiment.
The specific embodiment
Below in conjunction with diagram, to a preferred embodiment of the present invention will be described in detail:
As shown in Figure 1, in a preferred embodiment of the invention, this lamp distribution regulates locking device to comprise the turning collar 1 being sleeved on rotationally on lamp main body 4, and one end is fixed on the locking shell fragment 2 on lamp main body 4.Luminous intensity distribution adjusting device 3 is connected to one end of turning collar 1, when turning collar 1 rotation, can drive 3 rotations of luminous intensity distribution adjusting device, the rotation of this luminous intensity distribution adjusting device 3 can regulate the distance (i.e. the focal length of this light fixture) between reflective mirror (not shown) and light source (not shown) in lamp holder, thereby reaches the object of luminous intensity distribution (optically focused or astigmatism).Because flashlight is most, adopt this kind of mode to carry out luminous intensity distribution, therefore, the luminous intensity distribution that this lamp distribution regulates locking device to be mainly used in flashlight regulates.
On turning collar 1 inner surface, be also provided with a plurality of continuous locking portions, the other end of locking shell fragment 2 supports successively with the side of a plurality of locking portions in turning collar 1 rotary course, because this locking shell fragment 2 has elasticity, the rotation of turning collar 1 can force this locking shell fragment 2 to produce deformation, locking shell fragment 2 produces a resistance contrary with turning collar 1 direction of rotation for recovering deformation meeting, thereby reaches locking object.This locking device can be in luminous intensity distribution adjustment process, effectively prevents because vibration, that sharply motion etc. brings is loosening and cause the problem of lamp distribution shakiness.
The above-mentioned a plurality of continuous locking portions that are arranged on turning collar 1 inner surface are along the inner periphery continuous distributed of turning collar 1, to guarantee anyway turning collar 1 rotates, and locking shell fragment 2 all can touch the side of locking portion.This locking portion can be the jut of continuous distributed at turning collar 1 inner surface, it between two adjacent juts, is the part of depression, the end of locking shell fragment 2 is to be positioned at this sunk part and with the contacts side surfaces of jut, be understandable that, the end of locking shell fragment 2 cannot be trapped in completely in depressed part and cannot rotate with anti-jam turning collar 1 so that its.
As shown in Figure 2.Preferably, this locking portion is the internal tooth 100 on turning collar 1 inner surface.Further, locking shell fragment 2 is provided with the support division of perk, and the end of this support division is bending, and this forniciform end contacts with the top flank profil of internal tooth 100 just.When turning collar 1 rotation, internal tooth 100 forms local engagement with bending end, forces support division generation deformation, and this support division produces a resistance with turning collar 1 direction of rotation and reaches locking object for recovering deformation.Forniciform end can guarantee that turning collar 1 does not occur that in rotation process card pauses or stuck phenomenon, even if turning collar 1 has a smoother rotation process.Understandable, the perk angle of support division is relevant with internal tooth 100, and the perk angle of this support division should be able to make it just to contact with the top flank profil of internal tooth 100; Perk angle too conference only contacts end with the top flank profil of internal tooth 100, do not have locking effect, and the too little end that can make of perk angle cannot contact with internal tooth 100 at all; Therefore should do one's utmost to avoid because of perk angle too large too little cause cannot be locking problem.
Further, above-mentioned locking shell fragment 2 has the support division of two perks, and two support divisions lay respectively at the two ends of locking shell fragment 2 and are symmetrical set, and the end of two support divisions is all outwardly-bent.When one of them support division of locking shell fragment 2 damages, another still can play locking effect.Understandable, also can on lamp main body 4, be symmetrical arranged two locking shell fragments 2, can make like this anti-loosing effect more guaranteed.
Preferably, the surface of lamp main body 4, is provided with the installation position for fixing locking shell fragment 2 on the position corresponding with above-mentioned locking portion, leave certain gap, to hold locking shell fragment 2 between this installation position and the inner surface of turning collar 1.Preferably, above-mentioned installation position is the end face 400 being recessed to form downwards on lamp main body 4, and locking shell fragment 2 is fixed on end face 400 by two screws.
Preferably, turning collar 1 is cylindric, comprises small end and large end, has greatly a stair-stepping transition portion between end and small end.Understandable, the internal diameter of small end is less than the internal diameter of large end, and the external diameter of end should equate with the external diameter of lamp holder end greatly, to guarantee the aesthetic property of product.Locking portion is arranged on the inner surface of small end, in large end, is fixed with for driving the protruding dish 5 of luminous intensity distribution adjusting device 3 rotations.Protruding dish 5 is sleeved on lamp main body 4 rotationally, and is fixed by screws in large end and the stair-stepping transition portion of small end.This protruding dish 5 is also provided with for connecting the screens of luminous intensity distribution adjusting device 3, this screens can be the groove that size and shape and luminous intensity distribution adjusting device 3 ends adapt, the end of luminous intensity distribution adjusting device 3 and this groove engagement connection, when protruding dish 5 rotates along with turning collar 1, this luminous intensity distribution adjusting device 3 is rotation thereupon also.
In another specific embodiment of the present invention, use above-mentioned lamp distribution to regulate the light fixture of locking device to comprise lamp main body 4, luminous intensity distribution adjusting device 3, above-mentioned luminous intensity distribution regulates locking device to be arranged on lamp main body 4, and is connected with luminous intensity distribution adjusting device 3.Adopt after above-mentioned locking device, the luminous intensity distribution degree of accuracy meeting of light fixture is higher, has solved the luminous intensity distribution misalignment problem that light fixture causes because of vibrations.
Above embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement accordingly, can not limit the scope of the invention.All equalizations of doing with the claims in the present invention scope change and modify, and all should belong to the poor scope of culvert of the claims in the present invention.
