Description

Technical Field

[0001] The utility model belongs to the technical field of self-tapping screws, in particular to an anti-loosening and anti-slip self-tapping screw. Background Art

[0002] Self-tapping screws, also known as quick-thread screws, are quick-install fasteners made of steel with a galvanized, passivated surface. They are primarily used to connect thin metal sheets (such as steel and sawn metal). To connect, a threaded hole is first created in the connected component, and the self-tapping screw is then screwed into the threaded hole.

[0003] During the use and tightening process of the self-tapping screw, the screw may become loose and fall off due to the shaking of the object, which makes the functionality of the screw poor and affects the service life of the object. For this reason, we propose an anti-loosening and anti-slip self-tapping screw. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an anti-slip and anti-falling self-tapping screw, which effectively solves the problems raised in the background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: an anti-slip and anti-fall self-tapping screw, comprising a screw body and an anti-slip seat, wherein the anti-slip seat is engaged with the upper portion of the screw body, a sliding groove is provided on the inner side of the screw body, and toggle grooves are evenly provided inside the sliding groove;

[0006] A screw groove is provided inside the anti-slip seat, a positioning wire is provided inside the screw groove, a spring is provided on the inner side of the positioning wire, a top block is provided on the other end of the spring, and anti-slip grooves are evenly provided on the bottom of the anti-slip seat.

[0007] Preferably, a self-tapping head is provided at the bottom of the screw body, and the self-tapping head is made of alloy material.

[0008] Preferably, the toggle groove is opened in a "V" shape, the top block is set in a trapezoidal shape, and the front end of the top block is in contact with the toggle groove.

[0009] Preferably, a hexagonal block is provided on the upper portion of the screw body, and a hexagonal groove is provided inside the hexagonal block.

[0010] Preferably, a thread groove is provided inside the anti-slip seat, a bolt is provided inside the thread groove, the inner side of the bolt is arranged in a circular arc, and the inner side of the bolt is in contact with the sliding groove.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The anti-slip groove can be provided to prevent the bottom of the anti-slip seat from slipping. When the screw body rotates forward, the top block will automatically retract, allowing the screw body to rotate forward. The positioning wire can be provided to limit the position of the spring, so that the spring can better support the top block. The top block can be provided to engage the toggle groove, thereby preventing the screw body from rotating loose. When the screw body needs to be disassembled, the positioning wire can be removed to remove the spring and the top block, making it easier to rotate and disassemble the screw body.

[0013] 2. The V-shaped toggle groove allows the top block to be better disengaged from the inside of the toggle groove when rotating in the forward direction. When rotating in the reverse direction, the top block will engage with the toggle groove, thereby preventing the anti-slip seat from reversing and loosening.

[0014] 3. By providing a threaded groove, the bolt can be tightened. When the bolt is tightened, the inner side of the bolt will fit into the sliding groove, thereby limiting the anti-slip seat to prevent the anti-slip seat from falling off when the screw body is twisted, so that the screw body can be rotated and twisted better.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Embodiment 1, by Figure 1-4 Provided is an anti-slip and anti-fall self-tapping screw, comprising a screw body 10 and an anti-slip seat 20, wherein the anti-slip seat 20 is set on the upper part of the screw body 10, a sliding groove 11 is opened on the inner side of the screw body 10, and a toggle groove 12 is evenly opened inside the sliding groove 11;

[0024] The interior of the anti-slip seat 20 is provided with a screw groove 21, and the interior of the screw groove 21 is provided with a positioning wire 22. A spring 23 is provided on the inner side of the positioning wire 22, and a top block 24 is provided at the other end of the spring 23. The bottom of the anti-slip seat 20 is evenly provided with anti-slip grooves 25. When the device is in use, the anti-slip seat 20 can be set on the upper part of the screw body 10, and the screw body 10 can be rotated and self-drilled by twisting the screw body 10, so that the screw body 10 can be drilled and tightened. When the screw body 10 is used to drill and tighten the object, the bottom of the anti-slip seat 20 will fit with the object. By providing the anti-slip groove 25, the bottom of the anti-slip seat 20 can be prevented from slipping. When the screw body 10 is rotating forward, the top block 24 The screw body 10 can be automatically retracted to rotate forward. The positioning wire 22 can be used to limit the position of the spring 23, so that the spring 23 can better support the top block 24. The top block 24 can be used to engage the toggle slot 12, thereby avoiding the screw body 10 from rotating loose. When the screw body 10 needs to be disassembled, the positioning wire 22 can be removed to remove the spring 23 and the top block 24, so that the screw body 10 can be better rotated and disassembled. The bottom of the screw body 10 is provided with a self-tapping head, which is made of alloy material. The self-tapping head can make the screw body 10 more stable when rotating. The self-tapping operation is carried out well, and the self-tapping head made of alloy material can effectively avoid the deformation of the self-tapping head, thereby improving the service life of the screw body 10. The shape of the toggle groove 12 is "V"-shaped, and the shape of the top block 24 is trapezoidal. The front end of the top block 24 fits with the toggle groove 12. The toggle groove 12 opened in the V shape can make the top block 24 better disengage from the inside of the toggle groove 12 when rotating in the forward direction. When the top block 24 rotates in the reverse direction, the top block 24 will engage with the toggle groove 12, thereby avoiding the reverse loosening phenomenon of the anti-slip seat 20. A hexagonal block is provided on the upper part of the screw body 10, and a hexagonal groove is provided inside the hexagonal block. By providing the hexagonal block, The hexagonal block can be screwed by an electric wrench to drive the screw body 10 to rotate, and the hexagonal groove can be used to loosen it, and the screw body 10 can be disassembled when the hexagonal block is deformed. The interior of the anti-slip seat 20 is provided with a threaded groove, and a bolt is provided inside the threaded groove. The inner side of the bolt is arranged in a circular arc, and the inner side of the bolt fits with the sliding groove 11. The threaded groove can be provided to tighten the bolt. When the bolt is tightened, the inner side of the bolt will fit with the sliding groove 11, thereby limiting the anti-slip seat 20 to prevent the anti-slip seat 20 from falling off when the screw body 10 is screwed, so that the screw body 10 can be better rotated and screwed.

[0025] When the screw body 10 needs to be disassembled, the positioning wire 22 can be removed to remove the spring 23 and the top block 24, so that the screw body 10 can be rotated and disassembled better.
