Abstract
The contactless connected hidden screw includes shell body, fixed screw, screw cover connected on the shell body, graphite gasket placed in the bottom portion of the shell body, on the graphite gasket a spring is mounted, another end of spring is connected with turning block in which the permanent Nd-Fe-B magnet is set, upper end of the turning block is equipped with recessed groove, and on the upper surface of turning block a connecting screw is set, one end of the connecting screw is equipped with a projection block which can be fastened with the recessed groove on the turning block, its another end is placed in the screw cover and is screw-connected with inner screw thread set in one end of fixed screw, and the external screw-thread of the fixed screw can be single-screw or double-screw.
Description
Technical field
The invention belongs to the stealthy screw of a kind of contactless connection.
Background technique
Usually in furniture, decoration industry, often adopt demountable structure, the embedded aluminum rotational lock of a kind of side of utilization dish constitutes fastening system with the parallel spring bolt that forward communicates with locking plate on connecting, wherein the spring bolt the other end is bolted with and another object plastic nut connected vertically, and form right angle connects.Need outside screw-driver rotational lock owing to connect, the silhouette that locking plate exposes connecting plate rings attractive in appearance, and connect the rotary wedge face that is combined with, the pin arm of force is long, and set screw nut is lacked and is hard the cooperation, and millimetre-sized error is arranged when therefore installing, easily loosening under external force effects such as vibration, twisting after the locking, be applied to easily make on furniture, the decoration installation material distortion, loosening, cause finished product insecure, influence outward appearance and load capacity; Because it is big and many that the aperture is installed, and be rubbing contact with link, therefore cause alignment error easily, after repeated disassembled and assembled, the damage of mounting hole is also bigger.
Summary of the invention
The object of the present invention is to provide the stealthy screw of a kind of contactless connection, adopt the structure that steel screw and nut are individually fixed in the two articles and rigidity is connected, solved common removable connector easily loosening, influence attractive in appearance and installation material caused the problem of damage.
Above-mentioned purpose adopts following technical proposals to realize:
The stealthy screw of a kind of contactless connection includes housing, retaining screw, on the housing
Face is connected with turnbuckle, the housing inner bottom part is provided with Graphite pad, Graphite pad is provided with spring, the spring the other end is connected with spin-block, is provided with permanent rubidium iron boron magnet in the spin-block, and the spin-block upper end is provided with groove, be provided with connecting screw above the spin-block, connecting screw one end has the projection that can engage with the spin-block upper groove, and the other end is located in the turnbuckle and is spirally connected with the set internal thread of retaining screw one end, and the retaining screw the other end is provided with outside thread.
The stealthy screw of the contactless connection of the present invention has the following advantages:
1. the present invention adopts cooperating of steel screw and nut, and precision reaches micron order, and what guaranteed to connect is firm, and can dismantle and not influence installation precision repeatedly;
2. behind use the present invention, the object joint does not have the mounting hole of appearing and fastener hole, reaches stealthy purpose, guarantees to connect the integrity of object;
3. installing/dismounting speed of the present invention is fast, does not lose accessory, also easy damaged not;
4. retaining screw of the present invention can adopt double-spiral structure, makes connection speed faster;
5. adopt bar shaped or the permanent rubidium iron boron magnet of cylindricality, improved utilization efficiency.
Description of drawings
Fig. 1 is the stealthy screw structural schematic representation of the contactless connection of the present invention.
Embodiment
Be described further below in conjunction with accompanying drawing:
As shown in Figure 1, the stealthy screw of a kind of contactless connection of the present invention, include housing 1, retaining screw 7, be connected with turnbuckle 6 above the housing 1, housing 1 inner bottom part is provided with Graphite pad 8, Graphite pad 8 is provided with spring 2, spring 2 the other ends are connected with spin-block 3, be provided with permanent rubidium iron boron magnet 4 in the spin-block 3, spin-block 3 upper ends are provided with groove, are provided with connecting screw 5 above the spin-block 3, and connecting screw 3 one ends have the projection that can engage with spin-block 3 upper grooves, the other end is located in the turnbuckle 6 and is spirally connected with the set internal thread of retaining screw 7 one ends, and retaining screw 7 the other ends are provided with outside thread.
