Description

Technical Field

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

[0002] Bolts are commonly used detachable fasteners in the mechanical field, consisting of a head and a threaded shank. Their core function is to work with a nut to connect two parts through a through-hole structure, achieving a fastening effect. Bolt anti-slip measures are primarily achieved through structural design, material selection, and process optimization to increase friction or prevent loosening, thus ensuring connection stability.

[0003] A high-strength, anti-slip bolt with publication number CN221591461U includes a bolt head and a threaded shank. The threaded shank is fixed to the bottom of the bolt head, and an anti-slip structure is provided at the middle position of the outer wall of the bolt head. The anti-slip structure includes a coating, a plastic steel washer, and a spring washer. An oiling structure is provided at the middle position of the top of the bolt head. This utility model, by incorporating an anti-slip structure, uses a coating that is actually a non-loosening adhesive. This non-loosening adhesive coating can withstand continuous vibration over a long period without the bolt loosening, making it one of the best anti-loosening technologies currently available. Furthermore, the plastic steel washer and spring washer are respectively provided on the threaded shank, further enhancing the anti-slip performance of the high-strength bolt and ensuring that the bolt's service life is not affected by vibration or other factors during long-term use, thereby achieving the goal of improving the anti-slip performance of the high-strength bolt.

[0004] The existing technology has the following shortcomings: During the use of existing bolts, the bolts are prone to wear on the washers during tightening. At the same time, the contact area between the bolt and the washer is exposed to the external environment and is subject to environmental corrosion, which can easily lead to adhesion and damage, making it impossible for workers to loosen the bolts, thus affecting the subsequent use of the bolts. Utility Model Content

[0005] The purpose of this invention is to provide a bolt with an anti-slip structure. The contact between the anti-slip washer and the connecting component increases the friction between the bolt and the connecting component. The movement of the movable pin between the limiting ring and the fixed collar reduces the wear of the bolt head on the anti-slip washer. At the same time, the protective sleeve protects the contact position between the bolt and the anti-slip washer, preventing the bolt head from being exposed to the outside environment and corroding. This ensures stable loosening of the bolt in the future, thus solving the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bolt with an anti-slip structure, comprising a bolt body, and further comprising:

[0007] An anti-slip mechanism is provided on one side of the outer wall of the bolt body, and an anti-slip nut is provided on the other side of the outer wall of the bolt body;

[0008] The anti-slip mechanism includes an anti-slip pad, a fixing ring is fixedly installed on one side of the anti-slip pad, a limiting ring is provided on the inner side of the fixing ring, a protective sleeve is movably sleeved on the outer side of the fixing ring, and a hexagonal protrusion is fixedly installed on the inner side of the protective sleeve.

[0009] Preferably, the bolt body includes a screw head, a screw rod is fixedly installed on one side of the screw head, the screw rod is movably inserted into the inner side of the anti-slip washer, and the outer wall of the screw rod away from the screw head is threadedly connected to the inner wall of the anti-slip nut.

[0010] Preferably, a movable pin is fixedly installed on one side of the outer wall of the screw head, and the movable pin is movably connected to the gap between the fixed collar and the limiting ring on the outer wall away from the screw head. Two fixed seats are fixedly installed on one side of the outer wall of the limiting ring.

[0011] Preferably, the anti-slip pad has mounting grooves at the top and bottom of its inner side, and the inner walls of the two mounting grooves are movably connected to the outer walls of the two fixed seats respectively. The left vertical section of the gap between the fixed collar and the limiting ring and the left vertical section of the movable pin are both set as T-shaped.

[0012] Preferably, the top and bottom of the outer wall of the screw head are provided with fixing grooves, and the top and bottom of the inner wall of the protective sleeve are fixedly installed with plug-in plates, and the inner walls of the two fixing grooves are respectively movably connected to the outer walls of the two plug-in plates.

[0013] Preferably, the outer diameter of the screw head is the same as the outer diameter of the fixing collar, and the outer diameter of the screw head is the same as the inner diameter of the protective sleeve.

[0014] Preferably, the outer diameter of the anti-slip pad is the same as the outer diameter of the anti-slip nut on the side closest to the screw head, and the front vertical section area of ​​the hexagonal protrusion is the same as the front vertical section area of ​​the inner hexagon of the screw head.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. The movement of the movable pin is limited by the limiting ring and the retaining collar, preventing wear on the anti-slip washer during bolt tightening and preventing the anti-slip washer from falling off the outside of the bolt. The anti-slip washer and anti-slip nut make the connection between the bolt and the connecting parts more secure, preventing bolt slippage. The protective sleeve protects the bolt head and the retaining collar, preventing the contact area between the bolt head and the anti-slip washer from being exposed to the external environment and causing adhesion and corrosion. The hexagonal protrusion protects the internal hexagonal groove of the bolt, preventing deformation due to corrosion. This allows workers to easily loosen the bolt and ensures its normal use afterward.

[0017] 2. The connection between the mounting slot and the fixed base allows for easy installation and removal of the limiting ring, enabling workers to easily install and replace the anti-slip pad. The connection between the fixed slot and the plug plate allows the protective sleeve to stably protect the contact position between the screw head and the anti-slip pad. Attached Figure Description

[0028] 3. Anti-slip nuts. Detailed Implementation

[0029] This utility model provides, for example Figure 1 The bolt shown includes a bolt body 1, and further includes:

[0030] The anti-slip mechanism 2 is provided on one side of the outer wall of the bolt body 1, and the anti-slip nut 3 is provided on the other side of the outer wall of the bolt body 1.

[0031] To prevent bolts from slipping during installation, such as Figure 1-3 and Figure 5-6 As shown, the anti-slip mechanism 2 includes an anti-slip pad 201, a fixing collar 202 fixedly installed on one side of the anti-slip pad 201, a limiting ring 204 provided on the inner side of the fixing collar 202, and a protective sleeve 206 movably sleeved on the outer side of the fixing collar 202. A hexagonal protrusion 208 is fixedly installed on the inner side of the protective sleeve 206. The anti-slip mechanism 2 is connected to the bolt body 1 through the fixing collar 202 and the limiting ring 204. The anti-slip pad 201 can increase the friction between the bolt body 1 and the connecting parts, which can prevent the bolt body 1 from sliding. The protective sleeve 206 can protect the bolt body 1 and the position where it contacts the fixing collar 202, which can prevent the bolt body 1 and the fixing collar 202 from being eroded by the environment and causing adhesion and damage. This allows the workers to easily loosen the bolt body 1 and ensures the normal use of the bolt body 1 in the future.

[0032] To make the connection between the bolt body 1 and the connecting parts more secure, such as Figure 1-2 and Figure 4 As shown, the bolt body 1 includes a screw head 101, and a screw rod 102 is fixedly installed on one side of the screw head 101. The screw rod 102 is movably inserted into the inner side of the anti-slip washer 201. The outer wall of the side of the screw rod 102 away from the screw head 101 is threadedly connected to the inner wall of the anti-slip nut 3. Through the anti-slip washer 201 and the anti-slip nut 3, the bolt body 1 can be stably connected to the connecting parts, which can prevent the bolt body 1 from slipping.

[0033] In order for the anti-slip mechanism 2 to stably prevent slippage on the bolt body 1, such as Figure 2-6As shown, a movable pin 103 is fixedly installed on one side of the outer wall of the screw head 101. The outer wall of the movable pin 103 away from the screw head 101 is movably connected to the gap between the fixed collar 202 and the limiting ring 204. Two fixing seats 205 are fixedly installed on one side of the outer wall of the limiting ring 204. The top and bottom of the inner side of the anti-slip pad 201 are provided with mounting grooves 203. The inner walls of the two mounting grooves 203 are movably connected to the outer walls of the two fixing seats 205 respectively. The left vertical section of the gap between the fixed collar 202 and the limiting ring 204 is connected to the left side of the movable pin 103. The vertical section is T-shaped. The connection between the fixing seat 205 and the mounting groove 203 allows the limiting ring 204 to be stably installed inside the fixing collar 202. The fixing collar 202 and the limiting ring 204 are made of elastic rubber material, which allows them to be easily fitted onto the outside of the movable pin 103. The fixing collar 202 and the limiting ring 204 can limit the movable pin 103, so that the anti-slip mechanism 2 can be stably connected to the bolt body 1, and the anti-slip mechanism 2 can stably prevent the bolt body 1 from slipping.

[0034] In order to ensure that the protective sleeve 206 stably protects the bolt body 1 and the anti-slip mechanism 2, such as Figure 2-6 As shown, the top and bottom of the outer wall of the screw head 101 are provided with fixing grooves 104, and the top and bottom of the inner wall of the protective sleeve 206 are fixedly installed with plug-in plates 207. The inner walls of the two fixing grooves 104 are movably connected to the outer walls of the two plug-in plates 207 respectively. The outer diameter of the screw head 101 is the same as the outer diameter of the fixing collar 202, and the outer diameter of the screw head 101 is the same as the inner diameter of the protective sleeve 206. The outer diameter of the anti-slip washer 201 is the same as the outer diameter of the side of the anti-slip nut 3 closest to the screw head 101. The front vertical section area of ​​the hexagonal protrusion 208 is the same as the front vertical section area of ​​the inner hexagon of the screw head 101. The fixing groove 104 is connected to the plug plate 207, so that the protective sleeve 206 can be stably fitted onto the outside of the screw head 101. The protective sleeve 206 can protect the contact position between the screw head 101 and the fixing collar 202. At the same time, the hexagonal protrusion 208 can fill and protect the inner hexagonal groove of the screw head 101. The protective sleeve 206 is made of rubber material.

[0035] When installing the bolt body 1, the limiting ring 204 is fitted onto the outside of the screw 102 to support the two movable pins 103. Simultaneously, the anti-slip pad 201 is fitted onto the outside of the screw 102, allowing the two mounting slots 203 to be fitted onto the outside of the two fixing seats 205 respectively. This also allows the fixing ring 202 to be positioned outside the two movable pins 103. The gap between the fixing ring 202 and the limiting ring 204 then limits the movable pins 103. When connecting the bolt body 1 to the connecting component, the screw 102 is threaded into the inner side of the connecting component, allowing the anti-slip pad 201 to contact the surface of the connecting component. As the screw head 101 rotates, the movable pins 103 can be positioned within the fixing ring 202. The gap between the bolt body 1 and the limiting ring 204 is movable. After the bolt body 1 is fixed, the anti-slip nut 3 is sleeved onto the outer wall of the threaded rod 102 through the connecting component, so that the anti-slip nut 3 contacts the surface of the connecting component. Then, the protective sleeve 206 is sleeved onto the outside of the screw head 101, so that the two insertion plates 207 can be inserted into the two fixing slots 104 respectively, so that the hexagonal protrusion 208 can be inserted into the hexagonal groove inside the screw head 101, and thus the protective sleeve 206 can be sleeved onto the outside of the fixing ring 202, so that the protective sleeve 206 can protect the screw head 101 and the position where it contacts the fixing ring 202. This embodiment specifically solves the problem that the bolt and the washer are easily stuck and damaged due to environmental corrosion in the prior art.
