Abstract
The invention discloses an anti-loosening clamp. The anti-loosening clamp comprises a body, a bolt and a connecting plate. After the two ends of the body are connected in a lap joint manner, the two ends of the body and the bolt are fixed together through the connecting plate. The body is composed of a circular arc part and an expansion part. The expansion part protrudes outwards relative to the circular arc part. The anti-loosening clamp further comprises a circular arc plate and an elastic corrugated plate. The circular arc plate can slide relative to the expansion part. The circular arc plate is located on the inner side of the expansion part. An integral circular arc is jointly formed by the circular arc plate and the circular arc part. The elastic corrugated plate is located between the circular arc plate and the expansion part and fixedly connected with the circular arc plate. According to the anti-loosening clamp, when a pipeline is aged and fastening force is weakened, the elastic corrugated plate can expand the space between the expansion part and the circular arc plate through elastic deformation force of materials of the elastic corrugated plate, the fastening force of the pipeline is guaranteed, and leakage is prevented. Compared with the prior art, the sealing performance of the pipeline is improved.

Embodiment
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the present invention, and can not limitation of the present invention being interpreted as.
The structural perspective of the locking clip that Fig. 4 provides for the embodiment of the present invention, the structural front view of the locking clip that Fig. 5 provides for the embodiment of the present invention.
Embodiments provide a kind of locking clip 200, comprise body 210, bolt 220 and connecting plate 230.Wherein, body 210 is banded, and after the two ends of body 210 overlap mutually, is fixed together by connecting plate 230 and bolt 220.In the means of fixation of body 210 and bolt 220 and prior art, the means of fixation of body and bolt is identical, and particularly, it is circular that the two ends of body 210 overlap rear formation mutually, after overlap joint, superposed one end body is provided with draw-in groove.Bolt 220 is provided with screw thread tongue, screw thread tongue matches with above-mentioned draw-in groove.Connecting plate 230 is connected with bolt 220 not having threaded partial fixing, and connecting plate 230 is fixedly connected with one end body being positioned at bottom.When swivel bolt 220, bolt 220 moves the one end driving body 210 to be positioned at bottom and moves, thus realizes tightening up of clip body 210, realizes pipeline and fixes.
The partial schematic diagram of the locking clip that Fig. 6 provides for the embodiment of the present invention, body 210 is made up of circular arc part 211 and dilatation portion 212, and dilatation portion 212 gives prominence to outwardly relative to circular arc part 211.This locking clip 200 also comprises circular arc plate 240 and elastic waveform stereoscopic plate 250, circular arc plate 240 can be fixedly connected with dilatation portion 212 relative sliding, circular arc plate 240 is positioned at the inner side in dilatation portion 212, and circular arc plate 240 and circular arc part 211 form complete circular arc jointly, thus adaptive with the outer wall of pipeline.
Elastic waveform stereoscopic plate 250 is between circular arc plate 240 and dilatation portion 212, and the intermediate portion of elastic waveform stereoscopic plate 250 is fixedly connected with circular arc plate 240.It will be understood by those skilled in the art that, elastic waveform stereoscopic plate 250 is fixedly connected with can realizes in several ways with circular arc plate 240, the intermediate portion of elastic waveform stereoscopic plate 250 can be fixedly connected with by buckle 270 with circular arc plate 240, the two also can be fixedly connected with by the mode of welding, as shown in Figure 6, the signal for being connected by buckle 270.
When connecting pipeline, by the extruding force of pipeline, circular arc plate 240 extrudes elastic waveform stereoscopic plate 250 and is out of shape.When after the aging distortion of pipeline, the extruding force of pipeline to circular arc plate 240 diminishes, and elastic waveform stereoscopic plate 250 is release elastic force when recovering deformation, thus the enclasping force that still can maintain pipeline, therefore avoid the seepage of pipeline, compared with prior art, improve the sealability of pipeline.
Preferably, dilatation portion 212, for being bent into trapezoidal steel plate, is made of one piece with circular arc part 211.Certain space is formed, for accommodating elastic waveform stereoscopic plate 250 between trapezoidal steel plate and circular arc part 211.
Circular arc plate 240 and elastic waveform stereoscopic plate 250 can be all steel plates, in the present embodiment, elastic waveform stereoscopic plate 250 is for being bent into the steel plate of W shape, utilize the structure of " W shape ", be provided with three place's linear contact lay between elastic waveform stereoscopic plate 250 and circular arc plate 240, three place's linear contact lay lay respectively at centre and the two ends of described elastic waveform stereoscopic plate 250.Have two place's linear contact lay between elastic waveform stereoscopic plate 250 and dilatation portion 212, in the process that body 210 is locked, the space between dilatation portion 212 and circular arc plate 240 reduces, and elastic waveform stereoscopic plate 250 is compressed distortion simultaneously.Once occur that plastic deformation etc. affects by fastening pipeline, when fastening force weakens, elastic deformation force by the material of elastic waveform stereoscopic plate 250 own acts on, elastic waveform stereoscopic plate 250 can prop up the space between dilatation portion 212 and circular arc plate 240, thus maintain the fastening force of whole pipeline, prevent the rapid decay of power.Be out of shape by the pressure elasticity of elastic waveform stereoscopic plate 250, after aging distortion occurs fastening sebific duct, elastic waveform stereoscopic plate 250 provides a radial force, reduces the interior circular diameter that circular arc plate 240 forms with circular arc part 211, ensure that the fit sealing of pipeline.
Being slidably connected between circular arc plate 240 and dilatation portion 212 can realize in the following manner: the two ends of circular arc plate 240 are provided with claw 260, and described claw 260 connects and fixes with described dilatation portion 212.Claw 260 can be bending-like, and circular arc plate 240 adopts the claw of bending-like to be connected with the Placement in dilatation portion 212, can keep relative sliding, and the resiliently deformable for elastic waveform stereoscopic plate 250 provides structural feasibility.Claw 260 can be U-shaped, the fixed structure of U-shaped claw, coming off of the good peventing member of energy, and circular arc plate 240 and dilatation portion 212 can be made again to realize relative sliding, prevents from, in the process of body locking distortion, additionally bearing the deforming force of circular arc plate 240.
Structure of the present invention, feature and action effect is described in detail above according to graphic shown embodiment; the foregoing is only preferred embodiment of the present invention; but the present invention does not limit practical range with shown in drawing; every change done according to conception of the present invention; or be revised as the Equivalent embodiments of equivalent variations; do not exceed yet specification with diagram contain spiritual time, all should in protection scope of the present invention.
