Description

Technical Field

[0001] The utility model relates to the technical field of anti-slip screws, in particular to an anti-slip screw. Background Art

[0002] Anti-slip screws are also called self-locking screws. The purpose of this screw is to imitate the looseness of the nut, and the fine thread nut itself has a locking effect.

[0003] For example, an anti-slip screw with the authorization announcement number "CN217633364U" has grooves equidistantly processed on the outer wall of the edge block, and the inner wall of the groove at the top is plugged into the bottom of the outer wall of the vertical rod, and the front of the edge block is fixedly connected to the rear end face of the circular plate. The anti-slip screw is inserted into the interior of the groove by the vertical rod in the control structure, and then the vertical rod is held and rotated, and then the edge block is driven to rotate through the groove, so that the screw can be used normally, the screwing is convenient, and the limitation of use is eliminated. However, in the use of the anti-slip screw, the insertion rod for controlling the rotation of the anti-slip screw is in a split form. When the insertion rod is lost, the anti-slip screw cannot be rotated, and as the anti-slip screw is continuously screwed and approaches the object, the position of the insertion rod and the object will become tighter, so that the holding hand is not convenient to exert force and is easy to scratch the object, which increases the difficulty of using the anti-slip screw and leads to the limitation of use of the anti-slip screw. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An anti-slip screw is designed, including a round block and a groove, the rear end face of the round block is connected to a control structure, the rear of the control structure is connected to a screw, the control structure includes a nut and a straight plate, the front side of the nut is fixedly connected to the rear end face of the round block, the outer wall of the nut is fixedly connected to the inner sides of multiple straight plates, and the outer walls of the multiple straight plates are respectively fixedly connected to sheaths.

[0007] Preferably, the rear end face of the nut is fixedly connected to the front face of the screw.

[0008] Preferably, a curved block is fixedly connected to the rear end surface of the screw.

[0009] Preferably, a circular ring is fixedly connected to the rear end surface of the nut.

[0010] Preferably, a plurality of ridges are fixedly connected to the front sides of the plurality of circular rings.

[0011] Preferably, a groove is processed on the front side of the round block.

[0012] The utility model provides an anti-slip screw with the beneficial effects as follows: by controlling the contact between the fingers and the outer wall of the sheath in the structure, the fingers exert force to make the sheath rotate with the straight plate, the rotating straight plate rotates with the nut, the nut is subjected to force to gradually screw the screw into the object, the original form of holding the insertion rod is changed, when the nut is close to the connected object, it will not be scratched with the hand, the groove on the inner wall of the round block can be inserted with an external screwdriver, and the screwdriver can also rotate with force to make the round block rotate with the nut, thereby reducing the difficulty of using the anti-slip screw and eliminating the limitation of using the anti-slip screw.

[0018] The utility model is further described below in conjunction with the accompanying drawings:

[0019] Embodiment 1:

[0020] See also Figure 1-4 In this embodiment, an anti-slip screw includes a round block 1 and a groove 4. The rear end face of the round block 1 is connected to a control structure 2. The rear of the control structure 2 is connected to a screw 5. The control structure 2 includes a nut 201 and a straight plate 202. The front of the nut 201 is fixedly connected to the rear end face of the round block 1. The outer wall of the nut 201 is fixedly connected to the inner side of a plurality of straight plates 202. The finger is stuck at the straight plate 202 to facilitate the rotation of the nut 201. The outer walls of the plurality of straight plates 202 are respectively fixedly connected to sheaths 203, and the material of the sheaths 203 is rubber.

[0021] By controlling the fingers in the structure 2 to contact the outer wall of the sheath 203, the fingers exert force to make the sheath 203 rotate with the straight plate 202, and the rotating straight plate 202 rotates with the nut 201, and the nut 201 is subjected to force to gradually screw the screw 5 into the object, changing the original form of holding the insertion rod. When the nut 201 is close to the connected object, it will not scratch the hand. The groove 4 on the inner wall of the round block 1 can be inserted with an external screwdriver. The screwdriver can also rotate the round block 1 with the nut 201 by force, which reduces the difficulty of using the anti-slip screw and eliminates the limitation of the use of the anti-slip screw.

[0022] The rear end face of the nut 201 is fixedly connected to the front face of the screw 5, and a curved block 6 is fixedly connected to the rear end face of the screw 5. The outer wall of the curved block 6 is sloped to facilitate the insertion of the outer wall of the screw 5 behind the object connection. A circular ring 7 is fixedly connected to the rear end face of the nut 201, and multiple ridges 8 are fixedly connected to the front of multiple circular rings 7. A groove 4 is processed on the front of the circular block 1.

[0023] Working principle:

[0024] Anti-slip screw use:

[0025] The outer wall of the curved block 6 is inserted into the connection of the object, and then the fingers are in contact with the outer wall of the sheath 203. Then the fingers exert force to make the sheath 203 rotate with the straight plate 202, and the rotating straight plate 202 rotates with the nut 201. The nut 201 is subjected to force to gradually screw the screw 5 into the object, changing the original form of holding the insertion rod. When the nut 201 is close to the connected object, it will not be scratched by the hand. The groove 4 on the inner wall of the round block 1 can be inserted with an external screwdriver, and the screwdriver can also rotate the round block 1 with the nut 201 by turning it hard.

[0026] Anti-slip screw Anti-slip operation:

[0027] After the anti-slip screw is screwed in and installed, the ring 7 and the ridge 8 will contact the surface of the object, and the ridge will cause a certain amount of wear on the surface of the object, and then the ridge 8 will be embedded in the wear groove on the surface of the object. When the anti-slip screw rotates in the opposite direction, the ridge 8 will form a slot with the wear groove, thereby preventing the screw from slipping.

[0028] Embodiment 2:

[0029] See also Figure 1-4 In the present embodiment, an anti-slip screw further comprises a sleeve 3, the inner wall of the sleeve 3 is fixedly connected to the front end of the outer wall of the screw 5.

[0030] Working principle:

[0031] After the screw 5 is screwed into the object, the sleeve 3 will also enter the interior of the object. The sleeve 3 is made of plastic and will be squeezed and deformed after entering the object to increase friction, thereby improving the connection stability of the screw.

[0032] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
