[0001] The utility model relates to the technical field of nuts, in particular to an anti-theft nut with an anti-loosening effect. Background Art

[0002] A nut is a part that is screwed together with a bolt or screw to fasten things together. It is a component that all manufacturing machines must use. It is divided into several types according to the material, including carbon steel, stainless steel, and non-ferrous metals.

[0003] After searching, the patent number is CN217682746U, and the name is a utility model of a nut, including a nut body. Through research and analysis, it is found that although it has a relatively simple structure and therefore a relatively simple processing technology, it can be assembled using existing parts, so the production cost is low. However, it still has the following disadvantages to a certain extent.

[0004] For example, the nut is not easy to lock itself during use, and it may become loose due to external force during use, and it is easy to be unscrewed, which may easily cause the fixed equipment to be stolen. It is not easy to protect the connection between the nut and the bolt, and water can easily enter the connection between the bolt and the nut, causing the bolt and the nut to be eroded by rainwater. In order to solve the above technical problems, we have designed an anti-theft nut with anti-loosening effect. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-theft nut with an anti-loosening effect, which has the advantages of anti-loosening, anti-theft and rainproof, and solves the problem that it is inconvenient to lock itself, and it may become loose due to external force during use, which is inconvenient to fix the workpiece, and it is easy to be unscrewed, which makes the fixed equipment easy to be stolen.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-theft nut with anti-loosening effect, comprising an anti-theft bolt, a card slot is provided on the surface of the anti-theft bolt, a positioning slot is provided on the top of the anti-theft bolt, a nut body is provided on the surface threaded sleeve of the anti-theft bolt, a rotating sleeve is welded on the top of the nut body, a waterproof mechanism is provided on the top of the rotating sleeve, and an anti-detachment mechanism is provided on the surface sleeve of the anti-theft bolt.

[0007] Preferably, the waterproof mechanism includes a connecting rotating sleeve, the surface of the rotating sleeve is slidably connected to the connecting rotating sleeve, a telescopic waterproof sleeve is bonded to the top of the connecting rotating sleeve, a rotating block is inserted into the top of the positioning groove, a support plate is welded to the top of the rotating block, and the surface of the support plate is bonded to the telescopic waterproof sleeve.

[0008] Preferably, the bottom of the connecting sleeve contacts the nut body, the bottom of the supporting plate is slidably connected to the anti-theft bolt, and the surface of the rotating block is slidably connected to the positioning groove.

[0009] Preferably, the anti-disengagement mechanism includes a rotating sleeve, the top of the rotating sleeve is welded to the nut body, a positioning block is welded to the bottom of the rotating sleeve surface, the surface of the anti-theft bolt is sleeved with a mounting shell, the inner cavity of the mounting shell is welded with a clamping block, the surface of the clamping block is slidably connected to the positioning groove, a fixed block is welded to the inner wall of the mounting shell, an anti-reversal block is rotatably connected to the opposite side of the fixed block, a spring is connected to the opposite side of the fixed block by bolts, and the opposite side of the spring is connected to the anti-reversal block by bolts.

[0010] Preferably, a top fixed sleeve on the surface of the rotating sleeve is provided with a positioning ring plate, and the surface of the positioning ring plate is slidably connected to the mounting shell.

[0011] Preferably, a gasket is sleeved on the surface of the anti-theft bolt, and the top of the gasket is welded to the mounting shell.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model inserts the rotating block into the positioning groove, and the positioning groove positions the rotating block to prevent the support plate from sliding on the top of the anti-theft bolt. The telescopic waterproof cover can be telescopic to adapt to anti-theft bolts of different lengths. The telescopic waterproof cover is positioned by the mounting seat and the connecting rotating cover, so that the connecting rotating cover moves with the nut body. After the nut body is tightened, the connecting part of the anti-theft bolt and the nut body is covered by the telescopic waterproof cover to prevent rainwater from entering the connecting part of the anti-theft bolt and the nut body, and to prevent rainwater from corroding the anti-theft bolt and the nut body.

[0014] The utility model tightens the nut body by rotating it, and during the rotation process of the nut body, the rotating sleeve is driven to move up and down, and at the same time, the positioning ring plate and the positioning block are driven to rotate by the rotating sleeve. After the nut body is tightened, the elastic force provided by the spring causes the anti-reversal block to clamp the positioning block to prevent the nut body from rotating in a certain direction, and the mounting shell is positioned by clamping the clamping block into the clamping groove, thereby locking the nut body to the surface of the anti-theft bolt.
