Detailed Description

The technical solution of the present invention is further explained with reference to the drawings and the embodiments.

As shown in fig. 1 and 2, an embodiment of the present invention provides a shockproof slotted fastener, including a screw 1 and a nut 3, where a side wall of the screw 1 is fixedly connected to one end of an elastic component, the nut 3 is provided with a through groove 301, the other end of the elastic component is inserted into the through groove 301, a shallow groove 103 is provided on a surface of the screw 1, the shallow groove 103 is used for accommodating the elastic component, and the elastic component is arranged in an inclined manner;

nut 3 includes inserted sheet 4, washer 401, elbow 402 and spacing groove 302, has seted up in the nut 3 spacing groove 302, spacing groove 302 with lead to groove 301 intercommunication, two spacing groove 302 symmetry sets up lead to the both sides of groove 301, the one end of inserted sheet 4 is provided with elbow 402, elbow 402 corresponds elastic component sets up, washer 401 with 4 fixed connection of inserted sheet, washer 401 sets up in the spacing groove 302, inserted sheet 4 sets up lead to the inslot 301, two washer 401 symmetry sets up the both sides of inserted sheet 4, spacing groove 302 is used for the restriction the displacement of washer 401.

The detailed working process of the embodiment is as follows:

will screw rod 1 screw in during nut 3, elastic component by nut 3 extrudees, makes elastic component to shallow slot 103 draws in, because elastic component slope sets up elastic component rotates to when leading to groove 301's position, elastic component resets, makes elastic component's one end insert in leading to the inslot 301, makes blend stop 401 is in move in spacing groove 302, elastic component will inserted sheet 4 outwards supports out, when needs will screw rod 1 takes out, will inserted sheet 4 to lead to the extrusion in groove 301, make elbow 402 will elastic component extrudees, makes elastic component to screw rod 1 draws in, unscrew screw rod 1 again can. The setting of inserted sheet 4 makes screw rod 1 with the dismantlement work of nut 3 is more convenient, has saved the dismantlement time.

It should be noted that the limiting groove 302 is disposed parallel to the through groove 301, the limiting groove 302 is only communicated with the through groove 301, and the length of the baffle 401 is smaller than the depth of the limiting groove 302.

Owing to adopted elastic component, it has been solved and has had the bolt to become flexible easily under the vibrations environment among the prior art, causes harmful effects to the device, has the problem of potential safety hazard for the connection between screw rod 1 and the nut 3 is more firm, not only through threaded connection between screw rod 1 and the nut 3, still connects through elastic component, when taking place vibrations, screw rod 1 quilt elastic component is spacing, makes screw rod 1 can not take place to rotate, has promoted the stability of bolt, has prevented not hard up or drop of part, has avoided the technological effect that produces the potential safety hazard because of not hard up or drop of part.

The elastic assembly comprises a clamping strip 101 and a connecting sheet 102, one end of the connecting sheet 102 is fixed in the shallow groove 103, the other end of the connecting sheet 102 is connected with the clamping strip 101, and the clamping strip 101 is matched with the through groove 301. When the connecting piece 102 and the clamping strip 101 are extruded by the nut 3, the connecting piece 102 and the clamping strip 101 are extruded into the shallow groove 103, so that the connecting piece 102 and the clamping strip 101 are prevented from being pressed against the nut 3, and the screwing-in process of the screw rod 1 is not influenced. Elbow 402 corresponds card strip 101 sets up, is needing to be dismantled screw rod 1 with during the nut 3, it is convenient inserted sheet 4 will card strip 101 supports out lead to groove 301.

Preferably, to ensure the strength of the elastic member, the clip strip 101 and the connecting piece 102 are integrally formed. In order to ensure that the elastic component can be completely accommodated in the shallow groove 103 when being pressed by the nut 3, the size of the clamping strip 101 and the connecting piece 102 is smaller than or equal to the opening size of the shallow groove 103.

Furthermore, an included angle α is formed between the connecting piece 102 and the shallow groove 103, the angle α is greater than or equal to 30 degrees, the angle α is less than or equal to 60 degrees, and due to the included angle, when the elastic component is reset after being extruded by the nut 3, the clamping strip 101 can smoothly enter the through groove 301.

Preferably, in order to ensure that the clamping strip 101 can smoothly enter the through groove 301, the elastic component is L-shaped, the shallow groove 103 is provided with a plurality of grooves, and the elastic component and the through groove 301 are arranged corresponding to the shallow groove 103.

In order to ensure the overall strength of the bolt, the screw rod 1 and the elastic component should be integrally formed.

It should be noted that the connecting piece 102 has a curvature, and since the connecting piece 102 has a curvature, when the connecting piece 102 is pressed by the nut 3, the connecting piece 102 is more easily folded towards the shallow groove 103, and deformation of the elastic component is more facilitated, so as to further ensure that the elastic component is not clamped on the nut 3 when the screw 1 is screwed into the nut 3.

Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
