[0013] 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.

[0014] Reference Figure 1-4The present invention provides an embodiment of a security anti-tamper and anti-theft screw assembly, comprising an anti-theft cap 1 and a disassembly rod 10, characterized in that: the upper side of the inner wall of the anti-theft cap 1 is provided with multiple inclined grooves 8, the lower side of the inner wall of the anti-theft cap 1 is provided with multiple second slots 9, a cover 2 is snapped into the inner wall of the anti-theft cap 1, multiple movable rods 6 are fixedly connected to the bottom end of the cover 2, the outer wall of each movable rod 6 is provided with a first slot 7, a screw body 4 is provided on the inner wall of the anti-theft cap 1, a washer 3 is sleeved on the outer wall of the screw body 4, a special groove 5 is provided at the top of the screw body 4, and a protrusion is provided on the lower side of the outer wall of each movable rod 6, the size and shape of the protrusion matching the second slot 9; Specifically, after aligning the movable rod 6 on the cover 2 with the inclined groove 8 on the anti-theft cap 1, insert it. At this time, the protrusion on the surface of the movable rod 6 will be pushed by the inclined groove 8 to continuously bend the movable rod 6 into the cover 2 until the cover 2 is completely inside the anti-theft cap 1. At this time, the movable rod 6 will reset under its own elastic force, so that the protrusion is locked into the second slot 9 to complete the installation of the cover 2. At this time, the cover 2 and the anti-theft cap 1 will form a closed space to cover the top of the screw body 4, thereby playing a role in security and anti-theft, and the assembly is simple and convenient.

[0015] Reference Figure 5 and Figure 6 The top of the disassembly rod 10 is fixedly connected to a shaped card block 11. The size and shape of the shaped card block 11 match the shaped groove 5. The bottom of the disassembly rod 10 is fixedly connected to a fixing plate 12. The bottom of the fixing plate 12 is fixedly connected to multiple elastic rods 13. Each elastic rod 13 is fixedly connected to an insert block 14 at one end. The size of the elastic rod 13 matches the inclined groove 8. The outer wall of the insert block 14 is engaged with the inner wall of the first card groove 7. Specifically, the irregularly shaped locking block 11 at the top of the disassembly rod 10 fits into the irregularly shaped groove 5, allowing the screw body 4 to be installed and disassembled. The special shape of the irregularly shaped groove 5 and the central column make it impossible for ordinary octagonal screws to be used with the screw body 4. When disassembly is required, the operator can insert the elastic rod 13 at the bottom of the fixing plate 12 into the inclined groove 8 on the anti-theft cap 1, causing it to deform under the push of the inclined groove 8, thereby pushing the movable rod 6 to move. This causes the protrusion on the surface of the movable rod 6 to separate from the second locking groove 9 and release the limit, and the insert block 14 to be inserted into the first locking groove 7 on the movable rod 6. At this time, the operator can pull the fixing plate 12 outward to remove the cover 2 from the anti-theft cap 1, and then disassemble the screw body 4 through the disassembly rod 10.

[0016] Working principle: In actual use, the operator can first pass the screw body 4 through the through hole on the anti-theft cap 1 and put the washer on the outside of the screw body 4. Then, place the screw body 4 into the threaded hole to be installed, and then insert the irregularly shaped locking block 11 on the disassembly rod 10 into the irregularly shaped groove 5 at the top of the screw body 4. Rotate the disassembly rod 10 to complete the installation of the screw body 4. Then, press down on the multiple movable rods 6 on the cover 2, put the cover 2 into the anti-theft cap 1 and align the movable rods 6 with the inclined groove 8. Push the cover 2 into the anti-theft cap 1. At this time, the movable rods 6 will deform into the cover 2 under the action of the inclined groove 8 until the cover 2 is completely pushed in. Inside the anti-theft cap 1, the movable rod 6 will reset under its own elastic force and its surface protrusion will be inserted into the second slot 9 to complete the limit and cover the screw body 4. When disassembly is required, the operator can insert the elastic rod 13 at the bottom of the fixing plate 12 into the inclined groove 8 on the anti-theft cap 1, so that it is pushed by the inclined groove 8 to deform and thus push the movable rod 6 to move, so that the surface protrusion of the movable rod 6 separates from the second slot 9 to release the limit, and the insert 14 is inserted into the first slot 7 on the movable rod 6. At this time, the operator can pull the fixing plate 12 outward to remove the cover 2 from the anti-theft cap 1, and then disassemble the screw body 4 through the disassembly rod 10.

[0017] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
