Description

Technical Field

[0001] This utility model belongs to the field of U-bolt technology, and in particular relates to a U-bolt structure with anti-loosening function. Background Technology

[0002] U-bolts are non-standard parts with threads on both ends that can be used with nuts. They are mainly used to fix tubular objects such as water pipes or sheet objects such as leaf springs in automobiles.

[0003] The following problems exist with the application of U-bolts currently on the market:

[0004] 1. When using traditional U-bolts, the nut is usually directly put on the outside of the bolt and tightened. However, after long-term use or when the bolt is subjected to impact, the nut is prone to loosening, and its anti-loosening effect is poor.

[0005] 2. When traditional U-bolts are used, they are usually directly exposed to the environment after installation. When encountering rain or snow, rain and snow can easily accumulate on the surface of the fixing plate, which can easily cause corrosion at the connection over time, resulting in poor protection. Utility Model Content

[0006] The purpose of this utility model is to provide a U-bolt structure with anti-loosening function to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows: A U-shaped bolt structure with anti-loosening function includes a bolt body, a fixing plate on the top of the bolt body, a collar sleeved on the outside of the bolt body, a side plate fixedly connected to the side of the collar, a clamping plate on the side of the side plate, a sliding plate fixedly connected to the side of the clamping plate, a slider fixedly connected to the side of the sliding plate, the sliding plate being inserted inside the side plate, a first fixing plate fixedly connected to the top of the clamping plate, and a second fixing plate fixedly connected to the top of the side plate.

[0008] Preferably, a protective cover is fitted onto the top of the fixing plate, a first mounting block is fixedly connected to the side of the protective cover, a second mounting block is fixedly connected to the side of the fixing plate, a shaft is provided on the side of the second mounting block, a rotating rod is fitted onto the outside of the shaft, and the rotating rod is inserted into the first mounting block.

[0009] Preferably, a rubber ring is embedded inside the first fixing plate, and a rod is fixedly connected to the surface of the second fixing plate, with a ball head fixedly connected to one end of the rod.

[0010] Preferably, the collar has a connecting plate on its side, and the connecting plate is rectangular in shape.

[0011] Preferably, one end of the rotating rod is fixedly connected to a handle, and the handle is symmetrically distributed.

[0012] Preferably, the fixing plate is fixedly connected to the side of the first square plate, the protective cover is fixedly connected to the side of the second square plate, the positioning rod is fixedly connected to the surface of the first square plate, and the positioning rod is inserted into the second square plate.

[0013] The U-bolt structure with anti-loosening function of this utility model has the following advantages:

[0014] 1. This U-bolt structure with anti-loosening function is achieved by adding a fixing plate to the top of the bolt body, a collar sleeved on the outside of the bolt body, a side plate installed on the side of the collar, a clamping plate added to the side of the side plate, a sliding plate installed on the side of the clamping plate, a slider installed on the side of the sliding plate, the sliding plate being inserted inside the side plate, a first fixing plate installed on the top of the clamping plate, and a second fixing plate installed on the top of the side plate. When the bolt body is installed, the collar is directly sleeved on the outside of the nut. At this time, the clamping plate can be moved, causing the clamping plate to drive the sliding plate and the slider to move inside the side plate, so that the clamping plate is tightly attached to the side plate. The clamping plate is fixed by the first fixing plate and the second fixing plate. After the fixing is completed, the collar can fix the hexagonal nut and prevent the hexagonal nut from rotating, thus achieving a good anti-loosening effect.

[0015] 2. This U-bolt structure with anti-loosening function involves attaching a protective cover to the top of a fixing plate, installing a first mounting block on the side of the protective cover, and installing a second mounting block on the side of the fixing plate. A shaft is added to the side of the second mounting block, and a rotating rod is sleeved on the outside of the shaft. The rotating rod is inserted inside the first mounting block. After installation, the protective cover is fitted onto the surface of the fixing plate, and the rotating rod can be rotated, causing it to rotate outside the shaft and engage inside the first mounting block. This fixes the protective cover to the surface of the fixing plate, preventing rain and snow from accumulating on the surface and causing the bolt body to corrode. The protective effect is good.

[0027] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a U-shaped bolt structure with anti-loosening function.

[0028] like Figure 1-4 As shown, this utility model discloses a U-shaped bolt structure with anti-loosening function, including a bolt body 1, a fixing plate 2 on the top of the bolt body 1, a collar 10 sleeved on the outside of the bolt body 1, a side plate 8 fixedly connected to the side of the collar 10, a clamping plate 7 on the side of the side plate 8, a sliding plate 15 fixedly connected to the side of the clamping plate 7, a slider 16 fixedly connected to the side of the sliding plate 15, the sliding plate 15 being inserted into the side plate 8, a first fixing plate 18 fixedly connected to the top of the clamping plate 7, and a second fixing plate 19 fixedly connected to the top of the side plate 8. This is achieved by adding a fixing plate 2 to the top of the bolt body 1, a collar 10 sleeved on the outside of the bolt body 1, a side plate 8 mounted on the side of the collar 10, and a clamping plate 7 on the side of the side plate 8. The clamping plate 7 has a sliding plate 15 mounted on its side and a slider 16 mounted on its side. The sliding plate 15 is inserted into the side plate 8. A first fixing plate 18 is mounted on the top of the clamping plate 7, and a second fixing plate 19 is mounted on the top of the side plate 8. When the bolt body 1 is installed, the collar 10 is directly sleeved on the outside of the nut. At this time, the clamping plate 7 can be moved, so that the clamping plate 7 drives the sliding plate 15 and the slider 16 to move inside the side plate 8, so that the clamping plate 7 is tightly attached to the side plate 8. The clamping plate 7 is fixed by the first fixing plate 18 and the second fixing plate 19. After the fixation is completed, the collar 10 can fix the hexagonal nut and prevent the hexagonal nut from rotating, so that its anti-loosening effect is good.

[0029] A protective cover 22 is fitted onto the top of the fixing plate 2. A first mounting block 5 is fixedly connected to the side of the protective cover 22, and a second mounting block 6 is fixedly connected to the side of the fixing plate 2. A shaft 11 is provided on the side of the second mounting block 6, and a rotating rod 14 is fitted onto the outside of the shaft 11. The rotating rod 14 is inserted inside the first mounting block 5. By fitting the protective cover 22 onto the top of the fixing plate 2, installing the first mounting block 5 on the side of the protective cover 22, installing the second mounting block 6 on the side of the fixing plate 2, and adding a shaft 11 on the side of the second mounting block 6, with the rotating rod 14 fitted onto the outside of the shaft 11 and inserted inside the first mounting block 5, the protective cover 22 is fitted onto the surface of the fixing plate 2 after installation. At this time, the rotating rod 14 can be rotated, causing it to rotate outside the shaft 11 and engage inside the first mounting block 5. This fixes the protective cover 22 onto the surface of the fixing plate 2, preventing rain and snow from accumulating on the surface of the fixing plate 2 and causing the bolt body 1 to rust. The protective effect is good.

[0030] A rubber ring 17 is embedded inside the first fixing plate 18, and a rod 20 is fixedly connected to the surface of the second fixing plate 19. One end of the rod 20 is fixedly connected to a ball head 21. By embedding the rubber ring 17 inside the first fixing plate 18, installing the rod 20 on the surface of the second fixing plate, and installing the ball head 21 at one end of the rod 20, the rod 20 and the ball head 21 are inserted into the rubber ring 17, thus fixing the clamping plate 7.

[0031] The collar 10 has a connecting plate 9 on its side. The connecting plate 9 is rectangular in shape. By installing the connecting plate 9 on the side of the collar 10, it is convenient to fix the two collars 10 together.

[0032] One end of the rotating rod 14 is fixedly connected to the handle 13, which is symmetrically distributed. By installing the handle 13 at one end of the rotating rod 14, the rotating rod 14 can be easily rotated by holding the handle 13.

[0033] The first square plate 3 is fixedly connected to the side of the fixing plate 2, and the second square plate 4 is fixedly connected to the side of the protective cover 22. The positioning rod 12 is fixedly connected to the surface of the first square plate 3 and inserted into the second square plate 4. By installing the first square plate 3 on the side of the fixing plate 2 and the second square plate 4 on the side of the protective cover 22, and fixing the positioning rod 12 on the surface of the first square plate 3, the protective cover 22 can be easily positioned by inserting the positioning rod 12 into the second square plate 4.

[0034] The working principle of this U-bolt structure with anti-loosening function is as follows: When using this U-bolt, it is fixed by a nut, and the collar 10 is directly sleeved on the outside of the nut. At this time, the clamping plate 7 can be moved, causing the clamping plate 7 to drive the sliding plate 15 and the slider 16 to move inside the side plate 8, so that the clamping plate 7 is tightly against the side plate 8. The clamping plate 7 is fixed by the first fixing plate 18 and the second fixing plate 19. The rod 20 and the ball head 21 are inserted into the rubber ring 17, which fixes the clamping plate 7. After fixing, the collar 10 is closed. This will fix the hexagonal nut in place and prevent it from rotating. The protective cover 22 is then fitted onto the surface of the fixing plate 2. The positioning rod 12 is inserted into the second square plate 4 to easily position the protective cover 22. At this point, the handle 13 can be gripped and its rotating rod 14 can be rotated, causing the rotating rod 14 to rotate outside the shaft 11. This allows the rotating rod 14 to engage inside the first mounting block 5, thus fixing the protective cover 22 onto the surface of the fixing plate 2. This prevents rain and snow from accumulating on the surface of the fixing plate 2 and causing the bolt body 1 to rust, resulting in good protection.

[0035] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
