Technical Field
[0001] This utility model relates to the field of bolt technology, specifically to an anti-slip bolt. Background Technology
[0002] Fasteners, also known as standard parts in the market, are a general term for a class of mechanical parts used to fasten two or more parts (or components) together into a whole. Fasteners include bolts, studs, screws, nuts, washers, pins, retaining rings, weld studs, rivets, connecting pairs, wood screws, self-tapping screws, etc. Bolts: mechanical parts, cylindrical threaded fasteners that are used with nuts. They are a class of fasteners consisting of a head and a threaded shank (a cylinder with external threads). They need to be used with nuts to fasten two parts with through holes.
[0003] However, existing bolts still have some problems in use:
[0004] Existing bolts are generally composed of a screw and a nut, and are used as a set. During installation, the screw and nut are fastened by interlocking threads. When disassembly is required, the nut is turned in reverse. However, this connection method has a problem: if the outer wall of the drive head on the screw slips due to wear, disassembly becomes very difficult, or even impossible. If this happens to some high-value equipment or equipment that requires frequent maintenance, it will cause significant losses and inconvenience to production.
[0005] Therefore, we propose an anti-slip bolt to solve the problems mentioned above. Utility Model Content
[0006] The purpose of this utility model is to provide an anti-slip bolt to solve the problem mentioned in the background art. Bolts are generally composed of a screw and a nut and are used as a set. During installation, the screw and the nut are fastened by interlocking threads. When disassembly is required, the nut is turned in reverse. However, this connection method has the problem that once the outer wall of the drive head on the screw slips due to wear, disassembly becomes very difficult, or even impossible. If this happens to some high-value equipment or equipment that requires frequent maintenance, it will cause great losses and bring inconvenience to production.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an anti-slip bolt, comprising a bolt head and a hexagonal component:
[0008] A hexagonal piece is welded to the upper end of the bolt head, and a threaded post is welded to the lower end of the bolt head. A reinforcing nut is nested on the outer surface of the threaded post, and a retaining ring is fixed to the bottom end of the reinforcing nut. A locking block is fixedly installed on the outer surface of the retaining ring, and four sets of locking blocks are evenly arranged along the outer surface of the retaining ring. A reinforcing washer is nested on the outer surface of the threaded post, and an embedding groove is opened on the inner side of the reinforcing washer. A positioning groove is opened on the outer surface of the reinforcing washer.
[0009] By adopting the above technical solution, the reinforcing nut nested on the outer surface of the threaded column is connected to the reinforcing washer in a ring-shaped engagement through the locking block on the outer surface of the fixing ring. This can enhance the stability of the connection, ensure that the connected parts will not separate due to external force, and increase the anti-slip performance.
[0010] Preferably, the outer surface of the reinforcing nut has a hexagonal structure design, the inner rings of the reinforcing nut and the retaining ring are threaded, and the inner ring of the reinforcing washer is a smooth ring shape.
[0011] By adopting the above technical solution, the outer surface of the reinforcing nut is designed as a hexagonal structure, which makes it easy to tighten or disassemble using tools such as wrenches. The inner rings of both the reinforcing nut and the retaining ring are designed as threads, which makes it easy for the two to form a threaded fastening connection with the threaded post, further increasing the stability of the connection.
[0012] Preferably, the bottom end of the fixing ring is fitted to the inner bottom of the reinforcing pad, the locking block is adapted to the positioning groove, and the locking block is slidably connected to the embedding groove in an arc shape.
[0013] By adopting the above technical solution, the locking block on the outer surface of the fixing ring is embedded in the middle of the positioning groove, and by rotating the fixing ring, the locking block slides in an arc shape in the middle of the embedded groove, forming a locking connection. This can prevent the connection between the reinforcing nut and the reinforcing washer from shifting or falling off, thereby ensuring the anti-slip performance of the bolt.
[0014] Preferably, a fastening nut is nested on the outer surface of the threaded post, and the outer surface of the fastening nut has a hexagonal structure design, and the inner ring of the fastening nut is threaded. An anti-slip pad is fixedly connected to the upper end of the fastening nut, and the anti-slip pad is made of wear-resistant and anti-slip composite alloy material.
[0015] By adopting the above technical solution, the outer surface of the fastening nut is designed with a hexagonal structure, and the inner ring of the fastening nut is threaded, which enables the fastening nut and the threaded post to form a stable threaded connection. In addition, an anti-slip pad is added to the fastening nut to provide additional anti-slip effect for the bolt connection, further preventing the bolt from loosening under vibration or impact, and improving the safety and reliability of the connection.
[0016] Preferably, the outer surface of the threaded post is nested with an elastic washer, and the inner ring of the elastic washer has a smooth annular structure.
[0017] By using the above technical solution, by nesting an elastic washer on the outer surface of the threaded post, stress can be absorbed and dispersed during the use of the bolt, preventing bolt loosening or damage caused by stress concentration, effectively preventing bolt loosening and falling off, and improving the anti-slip performance of the bolt.
[0018] Preferably, a first rubber pad is adhered to the upper end surface of the anti-slip pad, and the outer surface of the first rubber pad has a raised structure design, and a second rubber pad is adhered to the lower end surface of the elastic pad, and the outer surface of the second rubber pad has a concave structure design.
[0019] By adopting the above technical solution, by designing the first rubber pad and the second rubber pad on the outer surfaces of the anti-slip pad and the elastic pad respectively, the friction coefficient at the connection can be increased, thereby increasing the anti-slip effect. Furthermore, by adding protrusions and concave structures to the outer surfaces of the first rubber pad and the second rubber pad, the protrusions and concave structures are interlocked and connected in a snap-fit manner, making the connection between the first rubber pad and the second rubber pad tighter and ensuring the stability of the connection.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] 1. When the reinforcing nut is tightened, the bottom end of the retaining ring fits against the inner bottom of the reinforcing washer, the locking block matches the positioning groove, and they slide in an arc shape. The locking block on the outer surface of the retaining ring is embedded in the middle of the positioning groove. By rotating the retaining ring, the locking block slides in an arc shape in the middle of the embedded groove, forming a locking connection. This can prevent the connection between the reinforcing nut and the reinforcing washer from shifting or falling off, thereby ensuring the anti-slip performance of the bolt, increasing the friction and stability of the connection, effectively preventing the bolt from loosening in a vibration or impact environment, and enhancing the stability of the bolt connection.
[0022] 2. A first rubber pad is adhered to the upper surface of the anti-slip pad. The outer surface of the first rubber pad has a raised structure design, which increases the contact area and friction with the connecting parts and prevents the bolts from loosening. A second rubber pad is adhered to the lower surface of the elastic washer. The outer surface of the second rubber pad has a concave structure design. It works with the first rubber pad to further enhance the stability and sealing of the connection. Through the combined use of the fastening nut, anti-slip pad, elastic washer and rubber pad, the stability and anti-slip performance of the bolt connection are effectively improved.
