Description

Technical Field

[0001] This utility model relates to the field of bolt technology, specifically to a U-bolt with a buffer connection structure. Background Technology

[0002] A bolt is a type of fastener consisting of a head and a threaded shank. It needs to be used with a nut to fasten two parts with through holes. This type of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated. Therefore, a bolted connection is a detachable connection. Bolts include U-bolts, also known as saddle bolts. U-bolts are non-standard parts, named for their U-shaped shape. They have threads at both ends that can be used with a nut. They are mainly used to fix tubular objects such as water pipes or sheet objects such as leaf springs in automobiles. Because the way they fix objects is like a person riding a horse, they are called saddle bolts.

[0003] However, existing U-bolts lack shock absorption mechanisms during use, resulting in direct contact between the U-bolt and the object, leading to significant impact force. This impact force can easily damage the connection between the U-bolt and the object, affecting the service life of the U-bolt. Therefore, we propose a U-bolt with a buffer connection structure. Utility Model Content

[0004] In view of the problems existing with the U-bolt with buffer connection structure, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a U-bolt with a buffer connection structure, which solves the problem that existing U-bolts lack shock absorption and buffering mechanisms during use, causing the U-bolt to directly contact the object with a large impact force. This large impact force can easily damage the connection between the U-bolt and the object, affecting the service life of the U-bolt.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A U-bolt with a buffer connection structure includes a U-bolt body, a limiting cylinder, and an arc-shaped limiting plate. Fixed plates are slidably provided on both sides of the U-bolt body, and an arc-shaped limiting plate is fixedly installed between the two fixed plates. Limiting cylinders are slidably provided on both sides of the U-bolt body located at the bottom of the fixed plates. Limiting posts are fixedly installed at the bottom of the two fixed plates, and the two limiting posts are slidably connected to the interiors of the two limiting cylinders. Limiting springs are fixedly installed inside the two limiting cylinders, and buffer seats are fixedly installed on the tops of the two limiting springs. A limiting hole is provided at the top of the U-bolt body.

[0008] Preferably, the U-shaped bolt bodies located at the bottom of the two limiting cylinders are fitted with wear-resistant rubber pads and spring washers.

[0009] Preferably, a rubber anti-slip pad is fixedly installed on the surface of the arc-shaped limiting plate.

[0010] Preferably, a limiting rod is threaded inside the limiting hole, and a silicone limiting block is fixedly installed at the bottom of the limiting rod.

[0011] Preferably, both sides of the bottom of the U-bolt body are threaded with fastening nuts.

[0012] Preferably, both of the buffer seats are silicone rubber blocks.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model utilizes a four-stage buffer structure consisting of a limiting spring, a silicone rubber buffer seat, a spring washer, and a wear-resistant rubber pad. This structure absorbs the impact force during the placement and use of objects, completely solving the problem of direct hard contact caused by the lack of a buffer mechanism in existing U-bolts. It effectively prevents damage to the connection between the U-bolt and the object due to excessive impact force, significantly reducing the risk of component damage. At the same time, the rubber anti-slip pad on the surface of the arc-shaped limiting plate, the silicone limiting block at the bottom of the limiting rod, and the wear-resistant rubber pad at the bottom form an all-round non-metallic protective layer, preventing direct contact between metal components and objects or mounting bases. This not only prevents scratches and corrosion on the object surface but also reduces wear on the U-bolt body, extending the service life of both.

[0015] 2. This utility model features a fixed plate that slides along the U-bolt body, and a limiting rod whose height can be adjusted via threads. This allows the device to adapt to tubular objects of different diameters or sheet objects of different thicknesses, eliminating the need to replace U-bolts of different specifications and reducing operating costs. The sliding and threaded adjustment design simplifies the installation process, allowing assembly to be completed without special tools, thus improving construction efficiency. Furthermore, the anti-slip effect of the rubber anti-slip pad, the radial limiting effect of the silicone limiting block, and the elastic pre-tightening effect of the spring washer synergistically enhance the connection stability between the device and the object, effectively addressing vibration and movement issues during use. It is suitable for various scenarios such as fixing water pipes, automotive leaf springs, and sheet components in industrial equipment, demonstrating strong practicality. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a U-bolt with a buffer connection structure.

[0024] This utility model provides, for example Figure 1-3 The U-bolt shown includes a U-bolt body 1, a limiting cylinder 2, and an arc-shaped limiting plate 3. Fixing plates 4 are slidably provided on both sides of the U-bolt body 1, and an arc-shaped limiting plate 3 is fixedly installed between the two fixing plates 4. Limiting cylinders 2 are slidably provided on both sides of the U-bolt body 1 located at the bottom of the fixing plates 4. Limiting posts 5 are fixedly installed at the bottom of the two fixing plates 4, and the two limiting posts 5 are slidably connected to the interior of the two limiting cylinders 2 respectively. Limiting springs 6 are fixedly installed inside the two limiting cylinders 2, and buffer seats 7 are fixedly installed on the top of the two limiting springs 6. A limiting hole 8 is provided at the top of the U-bolt body 1.

[0025] This utility model discloses a U-shaped bolt with a buffer connection structure, wherein the U-shaped bolt body 1 located at the bottom of the two limiting cylinders 2 is fitted with a wear-resistant rubber pad 9 and a spring washer 10.

[0026] This utility model discloses a U-shaped bolt with a buffer connection structure, wherein a rubber anti-slip pad 11 is fixedly installed on the surface of the arc-shaped limiting plate 3.

[0027] This utility model discloses a U-shaped bolt with a buffer connection structure. The limiting hole 8 is internally threaded with a limiting rod 12, and a silicone limiting block 13 is fixedly installed at the bottom of the limiting rod 12.

[0028] This utility model discloses a U-shaped bolt with a buffer connection structure, wherein fastening nuts 14 are threadedly connected to the bottom of both sides of the U-shaped bolt body 1.

[0029] This utility model discloses a U-shaped bolt with a buffer connection structure, wherein both buffer seats 7 are silicone rubber blocks.

[0030] When using it, first place the object to be fixed in the arc-shaped area of ​​the U-bolt body, so that the outer wall of the object makes initial contact with the rubber anti-slip pad 11 on the surface of the arc-shaped limiting plate 3. The rubber anti-slip pad 11 can increase the friction between the object and the arc-shaped limiting plate 3, prevent the object from sliding laterally during the subsequent fixing process, and initially isolate the metal arc-shaped limiting plate 3 from the object, reducing hard contact wear. After the object is placed in place, push the fixing plate 4 to slide along the U-bolt body, causing the arc-shaped limiting plate 3 to adhere to the surface of the object. At this time, the limiting post 5 at the bottom of the fixing plate 4 simultaneously extends into the limiting cylinder 2 and slides downward, squeezing the limiting spring 6 inside the limiting cylinder 2. The limiting spring 6 generates an elastic reaction force when compressed. This reaction force is transmitted to the limiting post 5 through the buffer seat 7, and then acts on the fixing plate 4 and the arc-shaped limiting plate 3, forming a primary axial buffer to offset the initial impact force when the object is placed. At the same time, the silicone rubber buffer seat 7 itself can generate elastic deformation to help absorb some of the impact energy, forming a secondary axial buffer. Rotating the limiting rod 12 in the limiting hole 8 at the top of the U-bolt body causes the limiting rod 12 to move downwards as it is threaded into the limiting hole 8, until the silicone limiting block 13 at the bottom is tightly attached to the top surface of the object. The silicone limiting block 13 not only avoids direct contact between the metal limiting rod 12 and the object, preventing scratches, but also adapts to the slight curvature of the object's surface through its own elastic deformation, achieving radial limiting and preventing the object from moving up and down during use, further enhancing the fixing stability. Wear-resistant rubber pads 9 and spring washers 10 are fitted on both sides of the bottom of the U-bolt body. The wear-resistant rubber pads 9 can isolate the U-bolt body from the surface curvature. The U-bolt body and the mounting base reduce metal wear during vibration. The spring washer 10 generates elastic preload force under the compression of the subsequent fastening nut 14, forming a three-stage buffer that can absorb the residual impact force generated by the vibration of the object during use. Finally, the fastening nuts 14 on both sides of the bottom of the U-bolt body are tightened, and the preload force of the nuts securely connects the entire device to the object and the mounting base, completing the assembly.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
