Permanent bolt

Abstract

A permanent bolt comprises a special bolt, a staple bolt fastening system and a nut. A clamping nail fastening system is arranged in the special bolt and comprises a clamping nail, a clamping pin, a clamping nail hole in the special bolt and a clamping pin hole in the special bolt. When not used, the staple bolt fastening system is hidden in the special bolt, and the bayonet lock is hidden in the bayonet lock hole and the staple bolt concave part and is not exposed; the staple bolt is of a cylindrical structure, and a column body is provided with anti-skid grains and is arranged in a staple bolt hole of the special bolt; when not in use, the staple bolt protrudes out. After a workpiece is riveted by the nut, the staple bolt fastening system is used, the staple bolt is knocked down by a hammer, and the staple bolt extrudes the bayonet lock from the concave part and penetrates out of the bayonet lock hole to transversely abut against the nut, so that permanent fixation is realized. The utility model has the beneficial effects that the bolt and the nut are transversely clamped by using a staple bolt fastening system, and cannot be loosened under the action of force in any direction, so that permanent fixation is realized.

Description

Technical Field

[0001] The utility model relates to a bolt, in particular to a permanent bolt. Background Art

[0002] Keeping bolts permanently secure is a special requirement in many important facilities. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a permanent bolt that can meet the special requirements of special facilities. In order to solve the above technical problem, the technical solution of the utility model is:

[0004] A permanent bolt includes three parts: a special bolt, a staple fastening system, and a nut; the special bolt contains a staple fastening system, including a staple, a bayonet, and a staple hole and a bayonet hole on the special bolt; when not in use, the staple fastening system is hidden in the special bolt, and the bayonet is hidden in the bayonet hole and the staple recess without showing its head; the staple is cylindrical, and the column has anti-skid patterns, and is placed in the staple hole of the special bolt; when not in use, the staple protrudes. After the nut rivets the workpiece, use the staple fastening system, and knock down the staple with a hammer, so that the staple squeezes the bayonet out of the recess, passes through the bayonet hole, and laterally tightens the nut, thereby achieving permanent fixation.

[0005] The utility model is beneficial in that:

[0006] Use the staple fastening system to clamp the bolts and nuts horizontally, and they will not loosen under the action of force in any direction, thus achieving permanent fixation. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The present invention is further described below in conjunction with the accompanying drawings to facilitate a better understanding of the present invention, but does not constitute a limitation of the present invention. Figure 1-2 As shown:

[0011] A permanent bolt 1 includes three parts: a special bolt 6, a clamp fastening system 2, and a nut 3; the special bolt 6 includes a clamp fastening system 2, including a clamp 10, a clamp pin 9, and a clamp hole 7 and a clamp pin hole 8 on the special bolt 6; when not in use, the clamp fastening system 2 is hidden in the special bolt 6, and the clamp pin 9 is hidden in the clamp pin hole 8 and the recess of the clamp 10 without showing its head; the clamp 10 is a cylindrical structure, and the column body has anti-skid patterns, and is placed in the clamp hole 7 of the special bolt 6. When not in use, the clamp protrudes; after the nut rivets the workpiece, the clamp fastening system 2 is used to knock down the clamp 10 with a hammer, and the clamp 10 squeezes the clamp pin 9 out of the recess, passes through the clamp pin hole, and laterally tightens the nut, thereby achieving permanent fixation.

[0012] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments, and modifications, deformations, and replacements of the present invention are still within the protection scope of the present invention.

Claims

1. A permanent bolt, characterized in that: It includes three parts: special bolts, staple fastening system and nuts. There is a staple fastening system inside the special bolt, including staples, pins, staple holes and pin holes on the special bolts. When not in use, the staple fastening system is hidden in the special bolt, and the pins are hidden in the pin holes and staple recesses without showing their heads. The staple is cylindrical in structure, with anti-slip grooves on the column body, and is placed in the staple hole of the special bolt. When not in use, the staple protrudes. After the nut has riveted the workpiece, use the staple fastening system, knock the staple down with a hammer, and the staple will squeeze the pin out of the recess, pass through the pin hole, and tighten the nut horizontally, thereby achieving permanent fixation.
