Description

The band fastener that a kind of rotation interlocks

The utility model relates to a kind of band button, the band fastener that particularly a kind of rotation interlocks.

Existing band fastener is formed by pin thread and box, becomes perfect though function heals, and member is more and more many, causes reliability to reduce, and must select material preferably for use again for improving reliability, causes cost to improve thus, thereby can't accomplish to make the best of both worlds.

The band fastener that the purpose of this utility model is to provide a kind of simple in structure, firm and durable, rotation easy to use to interlock.

The purpose of this utility model is to realize by following technical scheme:

The band fastener that rotation interlocks, comprise pin thread that constitutes by main buckled body, pin thread groove and pin thread cross bar and the box that constitutes by branched buckled body, box groove and box cross bar, pin thread is a nearly L shaped member, the pin thread groove that is used to connect main buckled body and pin thread cross bar is positioned at the corner of alphabetical L, box also is a nearly L shaped member, and the box groove that is used to connect branched buckled body and box cross bar is positioned at the corner of alphabetical L; Be provided with a spatula shape tongue piece parallel with the pin thread cross bar in the middle of the bottom front of main buckled body, the tongue piece is connected by column spinner with main buckled body; The branched buckled body bottom is provided with a vertical introducing port corresponding with the tongue piece in the middle of the rear end, introducing port extends inward as a slot corresponding with column spinner, slot top is a ring rotation groove that links to each other with introducing port, and slot, introducing port and box groove have formed the convex shape opening on the box.

Be provided with a louvre that prevents the plastics shrinking deformation in the middle of the tongue piece on the main buckled body, introducing port two outsides, branched buckled body bottom respectively are provided with a louvre that prevents the plastics shrinking deformation.

The utlity model has simple in structure, firm and durable, advantage easy to use, elegant in appearance.

Polycrystalline substance schematic diagram when Fig. 1 is the utility model pin thread, box separation;

Fig. 2 is that the A of pin thread among Fig. 1 is to structural representation.

Below in conjunction with drawings and Examples the utility model is further elaborated:

Pin thread 10 can be made with the rubber-like plastic material with box 11.

Referring to Fig. 1, Fig. 2, pin thread 10 is made of main buckled body 100, pin thread groove 14, pin thread cross bar 17, the bottom front of main buckled body 100 is provided with a spatula shape tongue piece 13, tongue piece 13 is parallel with pin thread cross bar 17, tongue piece 13 is connected by cylindrical column spinner 22 with main buckled body 100, and the middle part of tongue piece 13 also is provided with a louvre 20 that is used to prevent the plastics shrinking deformation.

Box 11 is by being made of branched buckled body 110, box groove 15, box cross bar 12, one introducing port 16 is arranged in the middle of the rear end, bottom of branched buckled body 110, introducing port 16 extends internally and forms a slot 21, slot 21, introducing port 16 and box groove 15 have constituted the convex shape opening on the box 11, top at slot 21, also be provided with a ring rotation groove 18 that links to each other with introducing port 16, be convenient to tongue piece 13 and insert the back half-twist with automatic fastening pin thread 10 and box 11, in two outsides of box 11 bottom introducing ports 16, a louvre 19 that is used to prevent the plastics shrinking deformation is arranged respectively.

Pin thread 10 is very simple with the fastening of box 11, only need to hold pin thread 10 and box 11 with the direction of quadrature, pin thread tongue piece 13 is aimed at box introducing port 16, inside gently one pushes away, pin thread tongue piece 13 is arrived in the box swivelling chute 18, the half-twist angle, then pin thread 10 has just been finished with the fastening of box 11.

Pin thread 10 and box 11 are threaded off, only need forward pin thread 10 to box 11 quadratures position, outside gently one pushes away, and after pin thread tongue piece 13 left introducing port 16, pin thread 10 and box 11 had just broken away from fully.

Pin thread groove 14 and pin thread cross bar 17 on the pin thread 10 are used to install band, and correspondingly box groove 15 on the box 11 and box cross bar 12 also are used for installing band.

Pin thread 10 and on member can with plastic material integrally formed, box 11 and on member also can be with plastic material integrally formed.
