Description

Technical Field

[0001] This utility model relates to the field of screw technology, specifically to a stabilizing mechanism for preventing screws from coming loose. Background Technology

[0002] Screws are a common type of fastener, mainly consisting of a threaded rod-shaped part and a matching nut. They are an important tool for firmly connecting two or more objects together. Anti-slip screws can play a certain role in preventing slippage by adding anti-slip and anti-loosening components to the nut. When using anti-slip screws, a stabilizing mechanism is used to improve the anti-slip effect.

[0003] However, when using the anti-loosening screw stabilizing mechanism to assist in the secondary stabilization of the anti-loosening screw, the stabilizing mechanism component requires additional drilling for installation, making the overall installation process cumbersome and time-consuming, which is a drawback.

[0004] Now, a new type of anti-loosening screw stabilizing mechanism is proposed to address the above-mentioned shortcomings. Utility Model Content

[0005] The purpose of this utility model is to provide a stabilizing mechanism for anti-loosening screws, so as to solve the problem mentioned in the background art of the inconvenience of installing the anti-loosening screw stabilizing mechanism.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stabilizing mechanism for anti-loosening screws, comprising a screw body, an anti-loosening nut rotatably connected to the outside of the screw body, a connecting block welded and fixed to the outside of the anti-loosening nut, and a fixing seat welded and fixed to the connecting block, the fixing seat having a threaded hole inside, and a connecting bolt provided at the top of the fixing seat.

[0007] Preferably, the fixing seat and the connecting block are fixed in three sets at equal intervals in a ring on the outer side of the anti-loosening nut.

[0008] Preferably, the threaded hole penetrates the interior of the fixing seat, and the connecting bolt is rotatably connected inside the threaded hole.

[0009] Preferably, the top of the anti-loosening nut is provided with a main body cover, and a split cover is fixed on the outside of the main body cover, and a through hole is opened inside the top of the main body cover.

[0010] Preferably, the through hole extends through the interior of the top of the main body cover, and the top of the screw body extends through the interior of the through hole.

[0011] Preferably, the split cover is fixed in three sets at equal intervals in a ring on the outside of the main cover, and the split cover is connected to the interior of the main cover.

[0012] Preferably, the screw body is provided with a sleeve on the outside, and the top of the sleeve is provided with a top hole, and the bottom of the sleeve is provided with a bottom hole.

[0013] Preferably, the top hole and the bottom hole penetrate the interior of the top and bottom ends of the sleeve, respectively, and the interiors of the top hole and the bottom hole are connected.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the anti-loosening screw stabilizing mechanism not only facilitates the installation of the anti-loosening screw stabilizing mechanism and facilitates external protection of the anti-loosening screw stabilizing mechanism, but also facilitates wear prevention of the thread stabilizing component;

[0015] (1) By setting anti-loosening nuts, fixing seats, connecting bolts, connecting blocks and threaded holes, when installing and using anti-loosening screws, after inserting the screw body into the connecting hole, the anti-loosening nut can be screwed into the outside of the screw body and locked. By using the screw body and anti-loosening nut to assist in the connection and fixation between the two separate parts, the bottom of the anti-loosening nut is integrally set with a washer and anti-slip texture, which can play an anti-loosening effect. At the same time, after the anti-loosening nut is locked, the connecting bolts can be screwed into the threaded holes on the three sets of fixing seats on the outside of the anti-loosening nut and pressed against the tightening mounting surface of the anti-loosening nut. The three sets of connecting bolts can increase the friction of the anti-loosening nut on the tightening mounting surface, which is convenient for secondary stabilization of the anti-loosening nut. There is no need to drill holes again during the installation process, just tighten and fix it, which improves the anti-loosening effect of the anti-loosening screw and facilitates the convenient installation of the anti-loosening screw stabilization mechanism.

[0016] (2) By setting a screw body, an anti-loosening nut, a split cover, a main body cover and a through hole, after the anti-loosening screw stabilizing mechanism is installed, the main body cover can be inserted into the outside of the screw body through the through hole at the top of the screw body. Then, the main body cover and the split cover are respectively inserted into the outside of the anti-loosening nut and the fixing seat. The split cover and the main body cover can provide auxiliary waterproof and dustproof protection for the outside of the stabilizing mechanism components, reducing the corrosion and damage of the stabilizing components.

[0017] (3) By providing a screw body, an anti-loosening nut, a sleeve, a top hole and a bottom hole, when disassembling and assembling the stabilizing mechanism component, the sleeve can be placed on the outside of the screw body and the bottom hole can be placed on the top of the anti-loosening nut. When using a socket or wrench to disassemble and assemble, the sleeve can be used directly to reduce the wear and stripping of the anti-loosening nut and facilitate the anti-wear protection of the thread stabilizing component.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figure 1-4 A stabilizing mechanism for anti-loosening screws includes a screw body 1, an anti-loosening nut 2 rotatably connected to the outside of the screw body 1, a connecting block 10 welded and fixed to the outside of the anti-loosening nut 2, and a fixing seat 3 welded and fixed to the connecting block 10. The fixing seat 3 has a threaded hole 11 inside, and a connecting bolt 4 is provided at the top of the fixing seat 3.

[0025] The fixing seat 3 and the connecting block 10 are respectively fixed in three sets at equal intervals in a ring on the outside of the anti-loosening nut 2. The threaded hole 11 penetrates the interior of the fixing seat 3, and the connecting bolt 4 is rotatably connected to the interior of the threaded hole 11.

[0026] Specifically, such as Figure 1 and Figure 2As shown, after inserting the screw body 1 into the connecting hole, the anti-loosening nut 2 can be screwed into the outside of the screw body 1 and locked. The screw body 1 and the anti-loosening nut 2 are used to provide auxiliary connection and fixation between the two separate parts. The bottom of the anti-loosening nut 2 is integrally provided with a washer and anti-slip texture, which can play an anti-loosening role. At the same time, after the anti-loosening nut 2 is locked, the connecting bolt 4 can be screwed into the threaded hole 11 on the three sets of fixing seats 3 on the outside of the anti-loosening nut 2 and pressed against the tightening mounting surface of the anti-loosening nut 2. The three sets can increase the friction of the anti-loosening nut 2 on the tightening mounting surface. There is no need to drill holes again during the installation process. It is easy to fix the anti-loosening nut 2 for a second time and improve the anti-loosening effect of the anti-loosening screw.

[0027] Example 2: The top of the anti-loosening nut 2 is provided with a main body cover 7, and a split cover 6 is fixed on the outside of the main body cover 7. A through hole 12 is opened inside the top of the main body cover 7. The through hole 12 penetrates the inside of the top of the main body cover 7. The top of the screw body 1 penetrates the inside of the through hole 12. Three sets of split covers 6 are fixed in a ring at equal intervals on the outside of the main body cover 7. The split covers 6 are connected to the inside of the main body cover 7.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, the main body cover 7 can be inserted into the outside of the screw body 1 through the through hole 12 at the top of the screw body 1. Then, the main body cover 7 and the split cover 6 are respectively inserted into the outside of the anti-loosening nut 2 and the fixing seat 3. The split cover 6 and the main body cover 7 can provide auxiliary waterproof and dustproof protection for the outside of the stabilizing mechanism components.

[0029] Example 3: A sleeve 5 is provided on the outside of the screw body 1, and a top hole 8 is provided inside the top of the sleeve 5, and a bottom hole 9 is provided inside the bottom of the sleeve 5. The top hole 8 and the bottom hole 9 pass through the interior of the top and bottom of the sleeve 5 respectively, and the interior of the top hole 8 and the bottom hole 9 are connected.

[0030] Specifically, such as Figure 1 and Figure 4 As shown, when disassembling and assembling screws, the socket 5 can be inserted onto the outside of the screw body 1, and the bottom hole 9 can be inserted into the top of the anti-loosening nut 2. When using a socket or wrench to disassemble and assemble the screw, the socket 5 can be used directly to reduce the wear and stripping of the anti-loosening nut 2 and to protect the thread-locking component from wear.

[0031] Working Principle: In use, when installing the anti-loosening screw, the screw body 1 is inserted into the connecting hole, and then the anti-loosening nut 2 is screwed into the outside of the screw body 1 for locking. The screw body 1 and the anti-loosening nut 2 provide auxiliary connection and fixation between the two separate components. The bottom of the anti-loosening nut 2 is integrally equipped with a washer and anti-slip texture to prevent loosening. After the anti-loosening nut 2 is locked, connecting bolts 4 can be screwed into the threaded holes 11 on the three sets of fixing seats 3 on the outside of the anti-loosening nut 2, and then pressed against the tightening mounting surface of the anti-loosening nut 2. The three sets of fixing seats increase the friction of the anti-loosening nut 2 on the tightening mounting surface. The installation process does not require drilling holes again for tightening. The anti-loosening nut 2 is then secured a second time. After the anti-loosening screw securing mechanism is installed, the main body cover 7 can be inserted into the outside of the screw body 1 through the through hole 12. Then, the main body cover 7 and the split cover 6 are respectively inserted into the outside of the anti-loosening nut 2 and the fixing seat 3. The split cover 6 and the main body cover 7 can provide auxiliary waterproof and dustproof protection for the outside of the securing mechanism component. When disassembling and assembling the securing mechanism component, the sleeve 5 can be inserted into the outside of the screw body 1, and the bottom hole 9 can be inserted into the top of the outside of the anti-loosening nut 2. When using a socket or wrench, the sleeve 5 can be directly used for disassembly and assembly, providing anti-wear protection for the thread securing component.
