Technical Field

[0001] The utility model relates to the technical field of nuts for engineering equipment, in particular to a shock-resistant and anti-loosening nut for engineering equipment. Background Art

[0002] During the assembly process of engineering equipment, bolts and nuts are often required. Bolts and nuts are used together to fasten and connect two engineering equipment components with through holes.

[0003] During the use of existing nuts for engineering equipment, the vibration of the engineering equipment causes the bolts and nuts to be subjected to the same vibration, which can easily cause relative slip between the inner thread of the nut and the outer thread of the bolt, loosening the nut and affecting the connection stability between the nut and the bolt. In view of this, we propose an anti-vibration and anti-loosening nut for engineering equipment. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a shock-resistant and anti-loosening nut for engineering equipment to solve the technical problem that during the use of the existing nuts for engineering equipment, due to the vibration of the engineering equipment machinery, the bolts and nuts are subjected to the same vibration, which easily causes the internal thread of the nut and the external thread of the bolt to slip relative to each other, causing the nut to loosen and affecting the connection stability of the nut and the bolt.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a seismic anti-loosening nut for engineering equipment, comprising a bolt body, a nut body is sleeved on the surface of the bolt body, a group of reinforcement mechanisms are symmetrically arranged on both sides of the nut body, and a limiting mechanism is arranged on the surface of the reinforcement mechanism;

[0006] The reinforcement mechanism includes a bracket, which is clamped in the nut body. The surface of the arc portion of the bracket is matched and fixed with an anti-slip concave-convex arc plate. A screw is provided on the side of the bracket away from the anti-slip concave-convex arc plate, and a T-shaped rotating rod is fixed on the end of the screw away from the bracket.

[0007] Preferably, a limiting groove matching and engaging with the bracket is provided inside the nut body, and the nut body and the screw rod are threadedly connected.

[0008] Preferably, one end of the screw rod away from the T-shaped rotating rod is movably engaged with the inside of the bracket, and the inner wall of the anti-slip concave-convex arc plate inside the bracket is tightly fitted with the surface of the bolt body.

[0009] Preferably, the nut body comprises a hexagonal nut, a fixing plate is fixedly connected to the top of the hexagonal nut, and a shock-absorbing pad is bonded to the surface of the fixing plate.

[0010] Preferably, the limiting mechanism includes a ring frame, which is movably sleeved on the surface of the T-shaped rotating rod, a groove frame is fixedly provided on the surface of the ring frame, a spring is provided inside the groove frame, a movable rod is connected to the top of the spring, a clamping block is fixedly connected to the top of the movable rod, and a pull rod is fixedly connected to the surface of the clamping block.

[0011] Preferably, a clamping groove matching the clamping block is provided on the surface of the fixing plate, and the clamping block forms an elastic structure with the slot frame through a movable rod and a spring.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model rotates the T-shaped rotating rod to make the screw rod translate inside the hexagonal nut, thereby effectively driving the bracket to move toward the bolt body until the anti-skid concave-convex arc plate inside the bracket is tightly fitted with the surface of the bolt body. The anti-skid concave-convex arc plate increases the friction between the bolt body and the bolt body, thereby reducing the possibility of the hexagonal nut turning loose.

[0014] 2. The fixing plate fixed to the top of the hexagonal nut in the utility model avoids direct contact between the hexagonal nut and engineering equipment, thereby reducing the wear on the surface of the hexagonal nut. At the same time, the shock-absorbing pad can effectively reduce the vibration force on the hexagonal nut.

[0015] 3. In the utility model, when the reinforcement mechanism is adjusted, the ring frame is rotated to make the block close to the fixed plate, and the pull rod is pulled downward to make the block and the movable rod move downward to compress the spring, so that the block is aligned with the slot provided on the surface of the fixed plate and matching with the block. Then, the pull rod is released, and the block is stuck in the slot under the influence of the spring rebound force, which effectively limits the horizontal direction of the T-shaped rotating rod and improves the stability of the reinforcement mechanism after adjustment.

[0026] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0027] A vibration-proof anti-loosening nut for engineering equipment, see Figures 1 to 6 , comprising a bolt body 1, a nut body 2 is sleeved on the surface of the bolt body 1, a group of reinforcement mechanisms 3 are symmetrically arranged on both sides of the nut body 2, and a limiting mechanism 4 is arranged on the surface of the reinforcement mechanism 3;

[0028] The reinforcement mechanism 3 includes a bracket 301, which is engaged with the inside of the nut body 2. The surface of the arc portion of the bracket 301 is matched and fixed with an anti-slip concave convex arc plate 302. A screw 303 is provided on the side of the bracket 301 away from the anti-slip concave convex arc plate 302, wherein a limiting groove matching and engaging with the bracket 301 is provided inside the nut body 2, and the nut body 2 and the screw 303 are threadedly connected. One end of the screw 303 away from the bracket 301 is fixed with a T-shaped rotating rod 304. Furthermore, one end of the screw 303 away from the T-shaped rotating rod 304 is movably engaged with the inside of the bracket 301, and the inner wall of the anti-slip concave convex arc plate 302 on the inner side of the bracket 301 is tightly fitted with the surface of the bolt body 1. The utility model rotates the T-shaped rotating rod 304 to make the screw rod 303 translate inside the hexagonal nut 201, thereby effectively driving the bracket 301 to move toward the bolt body 1 until the anti-skid concave-convex arc plate 302 on the inner side of the bracket 301 is tightly fitted with the surface of the bolt body 1. The anti-skid concave-convex arc plate 302 increases the friction between the bolt body 1, thereby reducing the possibility of the hexagonal nut 201 rotating loose.

[0029] It is worth noting that the nut body 2 includes a hexagonal nut 201, a fixing plate 202 is fixedly connected to the top of the hexagonal nut 201, and a shock-absorbing pad 203 is bonded to the surface of the fixing plate 202. In the utility model, the fixing plate 202 fixedly connected to the top of the hexagonal nut 201 avoids direct contact between the hexagonal nut 201 and the engineering equipment, thereby reducing the wear on the surface of the hexagonal nut 201, and the shock-absorbing pad 203 can effectively reduce the vibration force on the hexagonal nut 201.

[0030] It is worth mentioning that the limiting mechanism 4 includes a ring frame 401, which is movably mounted on the surface of the T-shaped rotating rod 304, and a groove frame 402 is fixedly arranged on the surface of the ring frame 401, and a spring 403 is arranged inside the groove frame 402. The top of the spring 403 is connected to a movable rod 404, and the top of the movable rod 404 is fixedly connected to a clamping block 405, wherein a clamping groove matching the clamping block 405 is provided on the surface of the fixed plate 202, and the clamping block 405 forms an elastic structure through the movable rod 404, the spring 403 and the groove frame 402, and a pull rod 406 is fixedly connected to the surface of the clamping block 405. In the utility model, when the reinforcement mechanism 3 is adjusted, the ring frame 401 is rotated to make the block 405 close to the fixed plate 202, and the pull rod 406 is pulled downward to make the block 405 and the movable rod 404 move downward to compress the spring 403, so that the block 405 is aligned with the groove provided on the surface of the fixed plate 202 and matching with the block 405. Then, the pull rod 406 is released, and the block 405 is stuck in the groove under the influence of the rebound force of the spring 403, which effectively limits the horizontal direction of the T-shaped rotating rod 304 and improves the stability of the reinforcement mechanism 3 after adjustment.

[0031] Working principle: Install the bolt body 1 on the engineering equipment, then turn the nut body 2 to tighten and fix it. At this time, the shock-absorbing pad 203 fits the surface of the engineering equipment to reduce the vibration force on the hexagonal nut 201. Then, by turning the T-shaped rotating rod 304, the screw rod 303 is translated inside the hexagonal nut 201, thereby driving the bracket 301 to move toward the bolt body 1, until the anti-skid concave-convex arc plate 302 on the inner side of the bracket 301 is tightly fitted with the surface of the bolt body 1, and the anti-skid concave-convex arc plate 302 increases the friction between the bolt body 1 and the bolt body 1. Thereby, the possibility of the hexagonal nut 201 turning loose is reduced, and then the ring frame 401 is rotated to make the block 405 close to the fixed plate 202, and at the same time, the pull rod 406 is pulled downward to make the block 405 and the movable rod 404 move downward to compress the spring 403, so that the block 405 is aligned with the groove set on the surface of the fixed plate 202 that matches the block 405, and then the pull rod 406 is loosened, and under the influence of the rebound force of the spring 403, the block 405 is stuck in the groove, thereby limiting the horizontal direction of the T-shaped rotating rod 304, thereby improving the stability of the reinforcement mechanism 3 after adjustment.

[0032] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
