Description

Stealthy fastener

Technical field

The utility model relates to fastener areas, specifically discloses a kind of fastener.

Background technique

Existing fastener many types generally comprise pin thread and box.

Existing fastener has following shortcoming: (1) structure is too simple, and outward appearance is not too attractive in appearance, and perhaps structure is too complicated, cost of production height, complex manufacturing; (2) lack safty device, deviate from easily after the installation, Safety performance is bad.

Summary of the invention

The utility model provides a kind of stealthy fastener of simple in structure, difficult drop-off.

In order to reach above technique effect, the technical solution of the utility model is as follows:

A kind of stealthy fastener comprises pin thread and box, and described box is provided with cavity, is equipped with first hole clipping on the relative two side on the described box, and described first hole clipping comprises first patchhole; One end of described pin thread is provided with the boss that can insert described first patchhole, and the end that described boss is connected with described pin thread is provided with the step of indent, it is characterized in that: also comprise the insurance shell fragment;

The spring sheet that is equipped with second hole clipping, spacing preiection and is arranged on the described second hole clipping place on the relative two side on the described insurance shell fragment, described second hole clipping comprises second patchhole that can insert described boss;

Described box is provided with on two sidewalls of described first hole clipping and is equipped with spacing hole;

When described insurance shell fragment inserted in the cavity of described box, described first hole clipping and described second hole clipping overlapped from outside to inside; Described first patchhole and described second patchhole overlap from outside to inside; Described spacing preiection is arranged at described spacing hole place.

Preferably, described first patchhole and described second patchhole are circular hole, elliptical aperture or square hole.

Preferably, described pin thread and box are square structure.

Preferably, described insurance shell fragment is the U-shaped structure.

Preferably, described insurance shell fragment is elastic material.

Use the technical solution of the utility model, have following technique effect: (1) stealthy fastener comprises pin thread, box and insurance shell fragment, and overall structure is simple; (2) when described insurance shell fragment inserted in the cavity of described box, described first hole clipping and described second hole clipping overlapped from outside to inside; Described first patchhole and described second patchhole overlap from outside to inside; Described spacing preiection is arranged at described spacing hole place, the boss of described pin thread inserts from described first patchhole and second patchhole, when firmly inwardly pressing described spring sheet pin thread is moved to the direction that is provided with spacing hole, described boss makes the step of described boss and described first hole clipping block mutually under the active force of described spring sheet, thereby realizes the auto lock of pin thread and box; When inwardly being pressed, described spring sheet moves pin thread towards the opposite direction of spacing hole, when sliding into first, boss inserts buckle, can take out pin thread from box, realize taking apart of pin thread and box, therefore, stealthy fastener of the present utility model has safety plate, can play safety effect, whole fastener difficult drop-off, Security is good.

Embodiment

Describe the technical solution of the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the technical solution of the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.

As shown in Figure 1, stealthy fastener of the present utility model comprises pin thread 1, box 2 and insurance shell fragment 3.

As shown in Figure 2, described box 2 is provided with cavity 21, is equipped with first hole clipping 22 and spacing hole 23 on the relative two side on the described box 2, and described first hole clipping 22 comprises first patchhole 221.

As shown in Figure 3, an end of described pin thread 1 is provided with the boss 11 that can insert described first patchhole 221, and the end that described boss 11 is connected with described pin thread 1 is provided with the step 12 of indent.

By Fig. 4, Fig. 5 as can be known, the spring sheet 33 that is equipped with second hole clipping 31, spacing preiection 32 and is arranged on described second hole clipping 31 places on the relative two side on the described insurance shell fragment 3, described second hole clipping 31 comprises second patchhole 311 that can insert described boss 11.

When described insurance shell fragment 3 inserted in the cavity 21 of described box 2, described first hole clipping 22 and described second hole clipping 31 overlapped from outside to inside; Described first patchhole 221 overlaps from outside to inside with described second patchhole 311; Described spacing preiection 32 is arranged at described spacing hole 23 places.

Described first patchhole 221 and described second patchhole 311 are circular hole, also can be designed to elliptical aperture or square hole according to the actual requirements.

Described pin thread 1 and box 2 are square structure, also can be designed to other shape according to the actual requirements.

Described insurance shell fragment 3 is selected elastic material for use, and is designed to the U-shaped structure.

Use stealthy fastener of the present utility model, have following technique effect: (1) stealthy fastener comprises pin thread, box and insurance shell fragment, and overall structure is simple; (2) when described insurance shell fragment inserted in the cavity of described box, described first hole clipping and described second hole clipping overlapped from outside to inside; Described first patchhole and described second patchhole overlap from outside to inside; Described spacing preiection is arranged at described spacing hole place, the boss of described pin thread inserts from described first patchhole and second patchhole, when firmly inwardly pressing described spring sheet pin thread is moved to the direction that is provided with spacing hole, described boss makes the step of described boss and described first hole clipping block mutually under the active force of described spring sheet, thereby realizes the auto lock of pin thread and box; When inwardly being pressed, described spring sheet moves pin thread towards the opposite direction of spacing hole, when sliding into first, boss inserts buckle, can take out pin thread from box, realize taking apart of pin thread and box, therefore, stealthy fastener of the present utility model has safety plate, can play safety effect, whole fastener difficult drop-off, Security is good.

The above is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection domain of the present utility model.
