Description

Technical Field

[0001] This utility model relates to the field of fasteners, and in particular to a fastener with vibration resistance and anti-loosening properties. Background Technology

[0002] Fasteners are a type of equipment used to connect, fix, and reinforce objects. Common fasteners include screws, nuts, washers, and pins. They are commonly used in industries such as machinery, construction, and automobiles to ensure a secure connection and proper operation between components, and are quite common in existing technologies.

[0003] Existing technologies, such as the utility model patent with publication number CN221347575U, disclose a fastener with anti-vibration and anti-loosening functions. This patent uses a screw, the inside of which has a long groove. The screw and the long groove are used to cooperate with a fastening component. The fastening component includes: an upper pressure ring that is sleeved on the outside of the screw during use; a rubber block is fixedly connected to the bottom end of the upper pressure ring; a lower pressure ring is fixedly connected to the bottom end of the rubber block; a sleeve is fixedly connected to the bottom end of the lower pressure ring; and a nut that rotatably sleeves on the outside of the rubber block is provided between the upper and lower pressure rings. This utility model, by combining the long groove on the screw with the upper pressure ring, nut, rubber block, lower pressure ring, and sleeve, effectively prevents the screw from being exposed to wind and rain through the sleeve. The upper pressure ring increases the friction between the nut and the object being fastened, thereby further improving the stability of the fastener in securing machine parts.

[0004] In the prior art, when personnel need to use fasteners to fix objects, they usually use bolts and nuts directly to fix them. If the object is in a vibrating environment for a long time, the bolts and nuts will move relative to each other due to continuous vibration, which will cause the fasteners to gradually loosen. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art where, when personnel need to use fasteners to fix objects, they usually use bolts and nuts directly. If the object is in a vibrating environment for a long time, the bolts and nuts will move relative to each other due to continuous vibration, causing the fasteners to gradually loosen. Therefore, this invention proposes a vibration-resistant and anti-loosening fastener.

[0006] To solve the above-mentioned technical problems, this utility model provides a vibration-resistant and anti-loosening fastener, comprising: a bolt, a nut threadedly connected to the arc surface of the bolt, a limiting structure provided inside the nut, the limiting structure including two retaining strips, a limiting groove and a moving ring, the two retaining strips being slidably connected to the nut, the moving ring being rotatably connected to the bolt, a limiting plate being slidably connected inside the auxiliary groove, a moving block being fixedly connected to the side of the two retaining strips that are far apart from each other, a spring being sleeved on the surface of the retaining strips, the two ends of the spring being fixedly connected to the moving block and the nut respectively, and two positioning grooves being formed on the inner wall of the moving ring.

[0007] The effect achieved by the above components is as follows: when personnel need to use nuts and bolts to fix objects, they rotate the bolts to make the moving ring slide into the inner wall of the limiting groove, and then make the two locking strips slide into the inner wall of the positioning groove. This can prevent the bolts and nuts from loosening during use, and improve the stability and reliability of the fasteners.

[0008] Preferably, the inner wall of the nut has two auxiliary grooves, the limiting groove communicates with the two auxiliary grooves, the inner wall of the auxiliary groove is slidably connected to a limiting plate, and the two limiting plates are fixedly connected to the moving ring.

[0009] The effect achieved by the above components is that the auxiliary groove and the limiting plate can limit the movement of the ring, making it easy for personnel to slide the movement of the ring into the inner wall of the limiting groove.

[0010] Preferably, a guide ring is fixedly connected to the side of the movable ring near the nut, and the guide ring is movably connected to the bolt.

[0011] The effect achieved by the above components is that the guide ring can drive the two locking strips to move, making it convenient for personnel to slide the locking strips into the inner wall of the positioning groove.

[0012] Preferably, the arc surface of the spring is fitted with a bellows, and the two ends of the bellows are fixedly connected to the moving block and the nut, respectively.

[0013] The effect achieved by the above components is that the bellows can protect the spring, prevent other substances from coming into direct contact with the spring during use, and extend the service life of the spring.

[0014] Preferably, the surface of the movable block is fixedly connected with an anti-slip sleeve.

[0015] The effect achieved by the above components is that the anti-slip sleeve can increase the friction between the person's hand and the moving block, and can prevent the person from slipping during the movement of the moving block.

[0016] Preferably, the card strip is a stainless steel strip.

[0017] The effect achieved by the above components is that the stainless steel strip has high strength and good wear resistance, which can prevent the strip from deforming during short-term use.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] Please see Figure 1 The present invention provides a vibration-resistant and anti-loosening fastener, comprising: a bolt 1, a nut 2 connected to the arc surface of the bolt 1 by a thread, and a limiting structure 3 provided inside the nut 2.

[0024] In the embodiments of this utility model, please refer to Figures 2 to 4The limiting structure 3 includes two locking strips 306, a limiting groove 301, and a moving ring 303. The two locking strips 306 are slidably connected to the nut 2, and the moving ring 303 is rotatably connected to the bolt 1. A limiting plate 302 is slidably connected inside the auxiliary groove 311. A moving block 308 is fixedly connected to the side of the two locking strips 306 that is far away from each other. A spring 310 is sleeved on the surface of the locking strip 306. The two ends of the spring 310 are fixedly connected to the moving block 308 and the nut 2, respectively. Two positioning grooves 304 are opened on the inner wall of the moving ring 303. When personnel need to use nut 2 and bolt 1 to fix an object, they rotate bolt 1 to allow the moving ring 303 to slide into the inner wall of the limiting groove 301, and then allow the two retaining strips 306 to slide into the inner wall of the positioning groove 304. This prevents bolt 1 and nut 2 from loosening during use, improving the stability and reliability of the fasteners. The inner wall of nut 2 has two auxiliary grooves 311, which are interconnected with the limiting groove 301. Limiting plates 302 are slidably connected to the inner walls of the auxiliary grooves 311, and the two limiting plates 302 are fixedly connected to the moving ring 303. The auxiliary grooves 311 and limiting plates 302 limit the moving ring 303, making it easy for personnel to slide the moving ring 303 into the inner wall of the limiting groove 301. A guide ring 305 is fixedly connected to the side of the moving ring 303 closest to nut 2, and the guide ring 305 is movably connected to bolt 1. The guide ring 305 can move the two locking strips 306, allowing personnel to easily slide the locking strips 306 into the inner wall of the positioning groove 304. A bellows 307 is fitted onto the arc surface of the spring 310, with both ends of the bellows 307 fixedly connected to the moving block 308 and the nut 2, respectively. The bellows 307 protects the spring 310, preventing direct contact between it and other substances during use, thus extending its service life. An anti-slip sleeve 309 is fixedly connected to the surface of the moving block 308. The anti-slip sleeve 309 increases the friction between the user's hand and the moving block 308, preventing slippage during movement. The locking strips 306 are made of stainless steel. Stainless steel has high strength and good wear resistance, preventing deformation of the locking strips 306 during short-term use. The working principle of the anti-vibration and anti-loosening fastener provided by this utility model is as follows: When a person needs to use nut 2 and bolt 1 to fix an object, the person can first move bolt 1 and nut 2 so that bolt 1 passes through the object and then the two limiting plates 302 slide into the inner wall of auxiliary groove 311 respectively. At this time, part of bolt 1 will also slide into the interior of nut 2. The auxiliary groove 311 and limiting plate 302 can limit the moving ring 303, which makes it convenient for the person to slide the moving ring 303 into the inner wall of limiting groove 301. Then the person can rotate bolt 1. When bolt 1 is turned, it causes the moving ring 303 to move closer to nut 2. The moving ring 303 causes the two limiting plates 302 and the guide ring 305 to move closer to nut 2. The guide ring 305 can move the two locking strips 306, making it easy for personnel to slide the locking strips 306 into the inner wall of the positioning groove 304 until the guide ring 305 and the moving ring 303 slide into the inner wall of the limiting groove 301. Then, during the sliding process of the guide ring 305 in the inner wall of the limiting groove 301, the arc surface of the guide ring 305 will interact with the inclined surface of the two locking strips 306. The two locking strips 306 abut against each other, and then the guide ring 305 drives the two locking strips 306 to move away from the guide ring 305. The locking strips 306 are made of stainless steel, which has high strength and good wear resistance, preventing deformation during short-term use. The locking strips 306 then drive the moving block 308 to move away from the guide ring 305, and the moving block 308 drives the anti-slip sleeve 309 to move away from the guide ring 305. The anti-slip sleeve 309 increases the friction between the user's hand and the moving block 308. To prevent slippage during the movement of the movable block 308, the movable block 308 also drives the bellows 307 and the spring 310 to stretch. The bellows 307 protects the spring 310, preventing other substances from directly contacting the spring 310 during use and extending the service life of the spring 310. The spring 310 then rebounds, causing the locking strip 306 to move closer to the positioning groove 304 until the locking strip 306 slides into the inner wall of the positioning groove 304.

[0025] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
