Description

Technical Field

[0001] This utility model relates to the field of nut technology, specifically to a structure for preventing loosening and disassembly of nuts. Background Technology

[0002] Regular nuts do not have anti-theft features. However, in some special applications, such as power transmission towers, railway projects, communication systems, and highways, anti-theft features are required to prevent damage by criminals. Anti-theft nuts are a type of nut, mainly used to prevent loosening and theft of mechanical component connections.

[0003] The existing anti-loosening and anti-removal structure of nuts is poor. After long-term use, the nuts are prone to loosening, which leads to a decrease in the strength of the connection and reduces safety. In addition, the nuts can be removed with a wrench, which makes it easy for theft of equipment to occur by removing the nuts.

[0004] Based on this, a structure for preventing loosening and unloading of nuts is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this utility model is to provide a structure for preventing loosening and unloading of nuts, so as to solve the problem of poor anti-loosening and anti-unloading structures in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The anti-loosening and anti-disassembly nut structure includes a hexagonal screw head, one end of which is fixedly connected to a threaded sleeve, and the other end of which is provided with a first mounting groove, and a rotating part is provided inside the first mounting groove;

[0008] One end of the rotating component is provided with an anti-loosening mechanism, one end of the threaded sleeve is provided with a sliding groove, and the outside of the hexagonal screw head is provided with an anti-dislodgement mechanism.

[0009] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

The threaded post is externally threaded to a sliding sleeve. The outer side of the threaded sleeve is provided with four equidistant annular limiting grooves. The outer side of the sliding sleeve is fixedly connected with four baffles at equal intervals, and the baffles pass through the limiting grooves through the threaded sleeve and extend to the outside.

[0011] In one alternative: the threaded sleeve is externally threaded to a nut body, and two washers are fitted outside the threaded sleeve and between the hexagonal screw head and the nut body.

[0012] In one alternative: the anti-discharge mechanism includes an anti-discharge cover, which is disposed outside the hexagonal screw head.

[0013] In one alternative: the inner wall of the anti-removal cover is fixedly connected with a locking block, and the outside of the hexagonal screw head is provided with a locking groove, and the locking groove is compatible with the locking block.

[0014] In one alternative: the sliding sleeve is located inside the sliding groove, and the horizontal center line of the threaded column coincides with the horizontal center line of the sliding sleeve.

[0015] In one alternative: the hexagonal screw head, threaded sleeve, threaded post, and anti-discharge cover are all made of austenitic stainless steel.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] After the nut body is locked with the threaded sleeve, the anti-loosening mechanism is installed with the threaded sleeve and the hexagonal screw head. Finally, an anti-disengagement mechanism is installed on the outside of the hexagonal screw head.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-4As shown, the anti-loosening and anti-disassembly nut structure includes a hexagonal screw head 1, one end of which is fixedly connected to a threaded sleeve 2, and the other end of the hexagonal screw head 1 is provided with a first mounting groove 3, and a rotating part 4 is provided inside the first mounting groove 3;

[0025] One end of the rotating component 4 is provided with an anti-loosening mechanism, one end of the threaded sleeve 2 is provided with a sliding groove 5, and the outside of the hexagonal screw head 1 is provided with an anti-dislodgement mechanism.

[0026] In this embodiment, a washer 11 is fitted over the threaded sleeve 2. One end of the threaded sleeve 2 is inserted into the pre-drilled hole, and another washer 11 is fitted over the threaded sleeve 2. The hexagonal screw head 1 is turned with a wrench to thread the threaded sleeve 2 onto the nut body 10. The two washers 11 provide a certain degree of anti-loosening. After the nut body 10 is locked to the threaded sleeve 2, the anti-loosening mechanism is installed on the threaded sleeve 2 and the hexagonal screw head 1. Finally, an anti-disengagement mechanism is installed over the hexagonal screw head 1. The anti-loosening mechanism effectively blocks the nut body 10, preventing it from loosening and improving the nut's loosening effect. This makes it safer to use. The anti-disengagement mechanism effectively prevents the removal of the anti-loosening mechanism. When the anti-loosening mechanism is not removed, the nut cannot be removed, thus providing an anti-disengagement function.

[0027] In one embodiment, such as Figure 3 and Figure 4 As shown, the anti-loosening mechanism includes a threaded post 6, which is disposed at one end of the rotating part 4 and located inside the sliding groove 5. A sliding sleeve 9 is threadedly connected to the outside of the threaded post 6. Four equidistant annular grooves 8 are formed on the outside of the threaded sleeve 2. Four baffles 7 are fixedly connected to the outside of the sliding sleeve 9, passing through the limiting grooves 8 and extending to the outside. The sliding sleeve 9 is located inside the sliding groove 5. The horizontal centerline of the threaded post 6 coincides with the horizontal centerline of the sliding sleeve 9. After the nut body 10 is installed, the baffles 7 and the limiting grooves are... Align 8 so that the sliding sleeve 9 enters the interior of the sliding groove 5. When the sliding sleeve 9 contacts the threaded post 6, use a tool to rotate the rotating part 4. The rotating part 4 drives the threaded post 6 to rotate, so that the sliding sleeve 9 moves outside the threaded post 6 until the baffle 7 contacts the nut body 10. At this time, the baffle 7 blocks the nut body 10, so that the nut body 10 cannot be loosened and moved, thus having an anti-loosening function. When it is necessary to disassemble the nut body 10, use a tool to rotate the rotating part 4 in the opposite direction to separate the sliding sleeve 9 from the threaded post 6. Then use a tool to rotate the hexagonal screw head 1 to separate the threaded sleeve 2 from the nut body 10, thus completing the disassembly.

[0028] In one embodiment, such as Figure 1 and Figure 2As shown, the threaded sleeve 2 is externally threaded to a nut body 10. Two washers 11 are fitted on the outside of the threaded sleeve 2 and between the hexagonal screw head 1 and the nut body 10. The washers 11 play a certain role in preventing loosening.

[0029] In one embodiment, such as Figure 2 and Figure 3 As shown, the anti-disassembly mechanism includes an anti-disassembly cover 12, which is disposed outside the hexagonal screw head 1. A locking block 13 is fixedly connected to the inner wall of the anti-disassembly cover 12. A locking groove 14 is provided on the outside of the hexagonal screw head 1, and the locking groove 14 and the locking block 13 are compatible. After the sliding sleeve 9 is installed, the anti-disassembly cover 12 is aligned with the hexagonal screw head 1, and the anti-disassembly cover 12 is pressed so that the locking block 13 is inserted into the inside of the locking groove 14, effectively installing the anti-disassembly cover 12 on the outside of the hexagonal screw head 1. At this time, the rotating part 4 is blocked to prevent the sliding sleeve 9 from being disassembled. Tools are needed to remove the anti-disassembly cover 12 first, thus providing a certain anti-disassembly function.

[0030] In one embodiment, such as Figure 1 and Figure 3 As shown, the hexagonal screw head 1, threaded sleeve 2, threaded post 6 and anti-removal cover 12 are all made of austenitic stainless steel, which improves the service life of the nut and makes it less prone to rust and damage.

[0031] The above embodiment discloses an anti-loosening and anti-disassembly nut structure. A washer 11 is fitted over the threaded sleeve 2. One end of the threaded sleeve 2 is inserted into a pre-drilled hole. Another washer 11 is fitted over the threaded sleeve 2. A wrench is used to rotate the hexagonal screw head 1, causing the threaded sleeve 2 to be threaded onto the nut body 10. After the nut body 10 is installed, the baffle 7 is aligned with the limiting groove 8, allowing the sliding sleeve 9 to enter the sliding groove 5. When the sliding sleeve 9 contacts the threaded post 6, a tool is used to rotate the rotating component 4. The rotating component 4 drives the threaded post 6 to rotate, causing the sliding sleeve 9 to move outside the threaded post 6 until the baffle 7 contacts the nut body 10. At this point, the baffle 7 blocks the nut body 10, preventing it from loosening and moving, thus providing an anti-loosening function.

[0032] After the sliding sleeve 9 is installed, align the anti-removal cover 12 with the hexagonal screw head 1 and press the anti-removal cover 12 so that the locking block 13 is inserted into the slot 14, effectively installing the anti-removal cover 12 onto the outside of the hexagonal screw head 1. At this time, the rotating part 4 is blocked, preventing the sliding sleeve 9 from being disassembled.

[0033] When it is necessary to remove the nut, first remove the anti-removal cover 12 with a tool, then use the tool to rotate the rotating part 4 in the opposite direction to separate the sliding sleeve 9 from the threaded post 6. Then use the tool to rotate the hexagonal screw head 1 to separate the threaded sleeve 2 from the nut body 10, thus completing the disassembly.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
