Description

Technical Field

[0001] This utility model relates to the field of bolt technology, specifically to an anti-slip bolt. Background Technology

[0002] Bolts are a common type of mechanical fastener, typically consisting of a threaded rod and a nut. Bolts are generally used to connect two or more materials and provide sufficient preload to ensure the reliability and safety of the connection. The design and selection of bolts should consider many factors, including the required preload, load-bearing capacity, environmental conditions, and material strength. Nuts typically consist of a threaded hole and a hexagonal shape, and can be used in conjunction with the threaded rod to control tightening and loosening. Currently, when using bolts, the tightened bolts may loosen or strip due to vibration, thus affecting the normal use by the user. To address the above problems, the inventor proposes an anti-slip bolt to solve these issues. Utility Model Content

[0003] In order to solve the problem that bolts may loosen or strip due to vibration during use, thus affecting normal use, the purpose of this utility model is to provide an anti-slip bolt.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: an anti-slip screw bolt, comprising a rod, a head fixedly connected to the top of the rod, anti-slip teeth fixedly connected to the bottom surface of the head, a notch provided in the middle of the bottom surface of the anti-slip teeth, an adhesive storage bag fixedly connected in the notch, a nut threadedly fitted on the side wall of the rod, the nut comprising an A surface and a B surface, anti-slip particles fixedly connected to the A surface, an adhesive filling port provided through the side wall of the nut, an annular groove provided inside the nut and on the side near the B surface, a rubber sleeve fixedly connected in the annular groove.

[0005] Preferably, the rod is a threaded rod, the diameter of the rod is smaller than the size of the head, and there are several anti-slip teeth, which are arranged in an array around the axis of the head. When installed and used with bolts, the head of the bolt is tightened so that the head is in close contact with the side wall of the object being fixed. The anti-slip teeth can be embedded into the object being fixed to improve the anti-slip performance and prevent stripping when the object vibrates.

[0006] Preferably, the glue storage bag contains adhesive. When the anti-slip teeth are embedded in the object being fixed, the glue storage bag will break under the pressure of the anti-slip teeth and the object, causing the adhesive inside the glue storage bag to flow out and bond the anti-slip teeth to the object. This makes the anti-slip teeth inside the object more secure, thereby improving the performance of the anti-slip thread. The A side of the nut faces the head, and the B side of the nut faces away from the head. There are several anti-slip particles, and these particles are arranged in an array around the axis of the nut. When the nut is installed with the rod, the A side of the nut must face the head so that the anti-slip particles can cooperate with the object being fixed, thereby increasing friction and preventing loosening after installation.

[0007] Preferably, one end of the glue-filling port extends into the threaded opening of the nut. There are six glue-filling ports, each located on one of the six faces of the nut, and the six glue-filling ports are staggered. After the nut and the rod are fitted together, the plug is removed, and glue is poured into the glue-filling port. This glue can be thread-locking glue or anaerobic glue. This glue can form a strong bond between the bolt and the nut, thereby preventing loosening and stripping. The staggered arrangement of the six glue-filling ports allows the glue to bond in different areas, improving the reliability of the bond. A plug is provided on one side of the nut, and the plug corresponds to and fits the glue-filling port. After the glue is poured, the plug is placed inside the glue-filling port to seal it.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: It provides a secure installation and excellent anti-slip performance. Anti-slip teeth are provided on the head of the bolt, allowing them to embed into the fixed object and improve anti-slip performance, preventing slippage when the object vibrates. An adhesive storage bag is provided at the anti-slip teeth; when the anti-slip teeth are embedded in the fixed object, the adhesive in the storage bag flows out to bond the anti-slip teeth to the fixed object, making the anti-slip teeth within the object more secure. Anti-slip particles are provided on the nut to increase friction with the fixed object, preventing loosening after installation. Additionally, an adhesive inlet is provided through the side wall of the nut; injecting adhesive into the inlet forms a strong bond between the rod and the nut, preventing loosening and slippage.

[0016] 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.

[0017] Example: Figure 1-5 As shown, this utility model provides an anti-slip screw bolt, including a rod 2, a head 1 fixedly connected to the top of the rod 2, an anti-slip tooth 3 fixedly connected to the bottom surface of the head 1, a notch 4 provided in the middle of the bottom surface of the anti-slip tooth 3, an adhesive storage bag 5 fixedly connected in the notch 4, a nut 6 threadedly fitted on the side wall of the rod 2, the nut 6 including an A surface 7 and a B surface 9, an anti-slip particles 8 fixedly connected on the A surface 7, an adhesive filling port 12 penetrating through the side wall of the nut 6, an annular groove 10 provided inside the nut 6 and on the side near the B surface 9, a rubber sleeve 11 fixedly connected in the annular groove 10, when the rod 2 moves to the rubber sleeve 11, the threads on the rod 2 will cut the rubber sleeve 11 and squeeze the rubber sleeve 11, so that the connection between the rod 2 and the nut 6 is tighter, thereby improving the anti-slip performance.

[0018] The rod 2 is a threaded rod, and the diameter of the rod 2 is smaller than that of the head 1. There are several anti-slip teeth 3, and the several anti-slip teeth 3 are arranged in an array with the axis of the head 1 as the center.

[0019] By adopting the above technical solution, when installing and using the bolt, the head 1 of the bolt is tightened so that the head 1 is in close contact with the side wall of the object being fixed. The anti-slip teeth 3 can be embedded in the object being fixed to improve the anti-slip performance and prevent the bolt from stripping when the object vibrates.

[0020] The adhesive is placed inside the glue storage bag 5.

[0021] By adopting the above technical solution, when the anti-slip teeth 3 are embedded in the fixed object, the glue storage bag 5 will break under the pressure of the anti-slip teeth 3 and the fixed object, so that the adhesive in the glue storage bag 5 will flow out to bond the anti-slip teeth 3 to the fixed object, thereby making the anti-slip teeth 3 located in the object more secure and improving the performance of the anti-slip thread.

[0022] The A-side 7 on the nut 6 faces the head 1, and the B-side 9 on the nut 6 faces away from the head 1. There are several anti-slip particles 8, and these particles 8 are arranged in an array with the axis of the nut 6 as the center.

[0023] By adopting the above technical solution, when the nut 6 is installed in conjunction with the rod 2, the A side 7 of the nut 6 should face the head 1 so that the anti-slip particles 8 can cooperate with the object being fixed, thereby increasing the friction and preventing loosening after installation.

[0024] One end of the glue-filling port 12 extends into the threaded opening of the nut 6. There are six glue-filling ports 12, which are located on the six faces of the nut 6 and are staggered with each other.

[0025] By adopting the above technical solution, after the nut 6 and the rod 2 are engaged, the plug 13 is removed and glue is injected into the glue inlet 12. This glue can be thread-locking glue or anaerobic glue. This glue can form a strong bond between the bolt and the nut 6, thereby preventing loosening and stripping. The six glue inlets 12 are staggered to allow the glue to bond in different areas, improving the reliability of the bond.

[0026] A plug 13 is provided on one side of the nut 6, and the plug 13 corresponds to and fits with the glue filling port 12.

[0027] By adopting the above technical solution, after the glue is poured, the plug 13 is placed inside the glue pouring port 12 to seal the glue pouring port 12.

[0028] Working principle: When this utility model is used for installation with bolts, the head 1 of the bolt is turned so that the head 1 is in close contact with the side wall of the object being fixed. The anti-slip teeth 3 can be embedded in the object being fixed to improve the anti-slip performance and prevent the thread from stripping when the object vibrates.

[0029] Furthermore, when the anti-slip teeth 3 are embedded in the fixed object, the glue storage bag 5 will break under the pressure of the anti-slip teeth 3 and the fixed object, so that the adhesive in the glue storage bag 5 will flow out to bond the anti-slip teeth 3 to the fixed object, thereby making the anti-slip teeth 3 located in the object more secure and improving the performance of the anti-slip thread.

[0030] When installing the nut 6 and the rod 2, the A side 7 of the nut 6 should face the head 1 so that the anti-slip particles 8 can cooperate with the object being fixed to increase friction and prevent loosening after installation. Then, remove the plug 13 and fill the glue inlet 12 with glue to form a strong bond between the rod 2 and the nut 6, thereby preventing loosening and stripping.

[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
