Description

Technical Field

[0001] The invention relates to a screw anti-theft sleeve. Background Art

[0002] In life, we often need to fix objects together so that others cannot open them. However, this requirement is not permanent. People often use welding to fix the connection, and then cut it when they need to open it. This is very troublesome and unsafe. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a screw anti-theft sleeve that is very convenient and safe to use. The screw anti-theft sleeve includes: a base and a cover, and the base and the cover are provided with corresponding locking structures. When in use, the position of the base and the cover can be locked by a lock.

[0004] The locking structure of the screw anti-theft sleeve is a cover-shaped structure in which the base and the cover are matched, and the base and the cover are provided with corresponding lock hole structures.

[0005] The screw anti-theft sleeve locking structure is a movable link between the base and the cover, and the base and the cover are provided with corresponding lock hole structures.

[0006] The corresponding lock hole structure of the screw anti-theft sleeve can be a hook-shaped lock hole provided on the base and a corresponding lock hole provided on the blocking cover.

[0007] The corresponding lock hole structure of the screw anti-theft sleeve is that a hook-shaped lock hole is provided on the blocking cover and a corresponding lock hole is provided on the base.

[0008] The corresponding lock hole structure of the screw anti-theft sleeve can be that the base and the cover are provided with corresponding lock holes.

[0009] The screw anti-theft sleeve is provided with a protrusion corresponding to the shape of the fixing plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] like Figure 5 As shown, place the 3rd base on the 8th fixing plate, turn the 7th screw to fix the 3rd base on the 8th fixing plate, and after the 3rd base is fixed on the 8th fixing plate, cover the 4th blocking cover so that the corresponding lock hole positions on the 3rd base and the 4th blocking cover match, and use the lock beam of the lock to pass through the 1st lock hole structure corresponding to the 3rd base and the 4th blocking cover, so that the 4th blocking cover covers the screw, and the 7th screw will not be touched by the screw-turning tool, and the technical problem can be solved.

[0017] like Figure 1 As shown, an embodiment of the present invention is to place the 3 bases on the 8 fixing plates, rotate the 7 screws to fix the 3 bases on the 8 fixing plates, and then cover them with the 4 blocking covers. Use the lock beam of a commonly used lock to pass through the lock hole structure, so that the 4 blocking covers can fix and cover the screws, so that the tool for turning the screws cannot contact the screws, and the screws can be prevented from being turned. In order to further fix the relative position of the screw anti-theft sleeve and the fixing plate, the screw anti-theft sleeve can also be welded to the fixing plate. In the scenario where the fixing plate is strip-shaped or has a concave shape, the bottom of the screw anti-theft sleeve can be provided with a corresponding protrusion. The protrusion can be set at the position where the edge of the fixing plate contacts the 3 bases or the 4 blocking covers. This makes the relative position of the screw anti-theft sleeve and the 8 fixing plates more secure. In many scenarios, there is no need to add this method of fixing the position of the screw anti-theft sleeve and the 8 fixing plates, because the screws are used in many environments and there are protrusions around the 8 fixing plates.

[0018] Figure 2 , Figure 3 , Figure 4 There are three cases of cover-like structures in which 3 bases and 4 blocking covers match each other. Place 3 bases on 8 fixing plates, turn the screws to fix 3 bases on 8 fixing plates, then cover 4 blocking covers, and pass the lock beam of the lock through the lock hole structure. In this way, 4 blocking covers can fix and cover 7 screws, so that the tool for turning 7 screws cannot contact the surface of 7 screws, and the fixing plate can be prevented from being opened.

[0019] Screws are a universal means of fixing and connecting. In life, we often encounter scenarios where we need to lock the screws to prevent them from rotating. The most common one is the battery of an electric vehicle. The metal strip serves as the battery's fixed plate. Many electric vehicle batteries use screws to fix the metal strip to prevent the battery from moving. Therefore, locking the metal strip of the electric vehicle battery can prevent the electric vehicle battery from being moved and stolen. In order to prevent the electric vehicle battery from being stolen, many people weld the metal strip to the electric vehicle and cut it open when changing the battery next time. This is very inconvenient and unsafe. This product can easily solve this problem.

[0020] Sometimes, for some reasons, we want to change people's travel routes, and we need to block certain routes and add temporary fences. In many cases, the fences are fixed together by welding, and then cut when they need to be opened again. This is very inconvenient and unsafe.

[0021] Screws are used as a conventional fixing method in many scenarios, so there are many scenarios that require separate opening and fixing. According to different scenarios, many products with different appearances can be designed. All of them are provided with corresponding locking structures on the base and the cover. When in use, the cover covers the screws so that the screws cannot be turned by tools, thereby achieving the fixing plate cannot be opened. All of these are within the scope of protection of this patent.
