Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel bolts, and more particularly to a stainless steel bolt with a long service life. Background Art

[0002] Stainless steel bolts are a commonly used fastener, but they still have some shortcomings in actual use. For example, after installation, the end part of the stainless steel bolt is usually directly exposed to the outside world. Therefore, during the long-term use of the bolt, its surface is easily corroded by external environmental factors such as moisture, causing corrosion and rust on the end surface, and even affecting the threaded part. Once rust begins, the rust layer formed is usually discontinuous, and the exposed fresh metal surface is more susceptible to further corrosion, forming a vicious cycle, accelerating the damage rate of the bolt, not only shortening the service life of the bolt, but even causing the bolt to loosen or become difficult to disassemble later, reducing the practicality of the bolt to a certain extent. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide a stainless steel bolt with a long service life, so as to solve the problem that the stainless steel bolts in the prior art are easily affected by external environmental factors and rust, resulting in a shortened service life.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a stainless steel bolt with a long service life, comprising a screw, the top of which is fixedly mounted with an end head, and the stainless steel bolt with a long service life also includes

[0005] A covering cover is slidably mounted on the surface of the end head;

[0006] A rotating end, the rotating end being rotatably mounted at the center of the top of the cover, the top surface of the rotating end being provided with a cross slot, and mounting rods being provided on opposite sides of the surface of the rotating end;

[0007] A fixing seat, which is fixedly installed on the periphery of the top of the covering cover, a connecting ring is movably installed inside the fixing seat, and a mounting seat is fixedly connected to one end of the connecting ring relative to the fixing seat, the bottom surface of the mounting seat is in contact with the top surface of the covering cover, and a clamping rod is provided inside the mounting seat, and one end of the clamping rod is clamped with the inside of the mounting rod.

[0008] It also includes a fitting disc and a sealing gasket. The fitting disc is rotatably connected to the bottom of the end head, and the sealing gasket is arranged on the top of the fitting disc. The surface of the sealing gasket fits with the bottom of the covering cover.

[0009] Wherein, it also includes an abutment component, which is arranged inside the screw.

[0010] The cam is secured to the cam face and is adapted to engage said support members, wherein the cam is secured to a position adjacent to the support members, and the cam is secured to said support members.

[0011] The beneficial effects of the above technical solution of the utility model are as follows:

[0012] In the above scheme, when installing the bolt, the cover is first moved upward as a whole to expose the surface of the end portion to leave space for accommodating the installation clamps. The bolt is then tightened as a whole by the installation clamps. After the bolt is tightened, the cover is moved downward as a whole to cooperate with the fitting plate to cover the surface of the end portion and the gap between the bolt and the installation portion, thus completing the installation and protection of the bolt. The covering and protection of the end portion surface by the cover can prevent the end portion from being affected by the external environment and rusting, thereby extending the service life of the bolt and ensuring that the subsequent bolt can be normally disassembled, thereby achieving the effect of improving the practicality of the device.

[0013] When the cover moves down and covers the end head, use a screwdriver to press against the top of the rotating end and contact with the cross slot, and rotate the rotating end counterclockwise ninety degrees. At this time, the flip plate connected to the rotating end by the connecting rod can rotate synchronously, and the side of the flip plate contacts the surface of the abutment plate to push the abutment plate toward the outside of the screw, so that the abutment plate can abut against the inner wall of the installation position, thereby reinforcing the bolt as a whole. Thereafter, by moving the mounting seat horizontally, the clamping rod is clamped with the mounting rod, that is, the rotating end is fixed, ensuring that the flip plate can be in close contact with the abutment plate, further improving the stability of the bolt after installation.
