Description

Technical Field

[0001] This utility model belongs to the field of U-bolt technology, and particularly relates to a U-bolt with a reinforced structure. Background Technology

[0002] U-bolts, also known as saddle bolts or snap ring bolts, are shaped like the letter U. They are made of low-carbon steel or stainless steel and have good machinability and corrosion resistance. Both ends are threaded and 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 reinforcement structure usually needs to be installed on the outside of the mounting surface during installation. Then, the external nut structure is tightened to fix it. Since there is no reinforcement structure installed, the expansion and contraction of the U-bolt will directly affect the position of the nut installation, and loosening will occur over time. Therefore, the reinforcement effect is weak when used.

[0005] 2. When most U-bolts are used, the outer side of the reinforcing plate is relatively smooth, requiring multiple tightening of the external fastening structure to reinforce and fix the reinforcing plate to the mounting surface. Since there is no structure installed to enhance friction, the fastening structure needs to be inspected regularly by the staff, so its anti-slip effect is weak when used. Utility Model Content

[0006] The purpose of this utility model is to provide a U-bolt with a reinforced structure 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-bolt with a reinforced structure includes a U-bolt body and a locking nut. The locking nut is externally threaded onto the U-bolt body and is symmetrically distributed. A reinforcing plate is sleeved on the outside of the U-bolt body, and a threaded rod is slidably connected inside the reinforcing plate. A sleeve is sleeved on the outside of the U-bolt body and is symmetrically distributed. An X-shaped rod is provided on the side of the sleeve, and a fixing plate is provided outside the X-shaped rod. A through hole is opened inside the fixing plate. A threaded rod is slidably connected to the side of the reinforcing plate and passes through the through hole. A wing nut is externally threaded onto the threaded rod.

[0008] Preferably, the other side of the reinforcing plate is provided with an anti-slip plate, the outer side of the anti-slip plate is provided with rubber strips, the rubber strips are evenly distributed, the anti-slip plate has mounting holes and limiting grooves inside, the mounting holes are inlaid with washers, the limiting grooves are inlaid with limiting rings, and the washers are provided with limiting rings on their sides.

[0009] Preferably, the reinforcing plate has a groove inside, a slider is embedded inside the groove, and a threaded rod is connected to the side of the slider.

[0010] Preferably, the side of the fixing plate is provided with a positioning block, the outer side of the reinforcing plate is provided with a positioning groove, and the positioning block is embedded in the positioning groove.

[0011] Preferably, a slot is provided on the other side of the reinforcing plate, and an insert plate is provided on the side of the anti-slip plate, the insert plate being embedded inside the slot.

[0012] Preferably, the reinforcing plate has mounting holes inside, and the U-bolt body passes through the mounting holes.

[0013] The U-bolt with a reinforced structure of this utility model has the following advantages:

[0014] 1. This U-bolt with a reinforced structure improves the strength of the U-bolt by sliding a threaded rod on the outside of the reinforcing plate and fitting a sleeve around the outside of the U-bolt body. An X-shaped rod and a fixing plate are installed on the outside of the sleeve. After the reinforcing plate is installed, the worker removes the reinforcing structure, fits the sleeve around the outside of the U-bolt body, inserts the threaded rod through the fixing plate, and then tightens the outer nut. The X-shaped rod installed in this way can enhance the support on both sides and prevent loosening due to shrinkage, thus providing a reinforced structure during use.

[0015] 2. This U-bolt with a reinforced structure enhances the anti-slip effect between the mounting surface and the contact surface by installing an anti-slip plate and a rubber strip on the outside of the reinforcing plate, installing a washer inside the anti-slip plate, and embedding an insert plate inside the slot. Before using the reinforcing plate, the worker removes the anti-slip structure and installs the insert plate in the slot, thus installing the anti-slip structure on the outside of the reinforcing plate. When it comes into contact with the mounting surface later, it can increase the friction and provide a strong anti-slip effect during application. Attached Figure Description

[0029] 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 with a reinforcing structure.

[0030] like Figure 1-6 As shown, this utility model discloses a U-bolt with a reinforced structure, comprising a U-bolt body 1 and a locking nut 2. The locking nut 2 is threaded onto the outside of the U-bolt body 1, and the locking nuts 2 are symmetrically distributed. A reinforcing plate 3 is sleeved on the outside of the U-bolt body 1, and a threaded rod 7 is slidably connected inside the reinforcing plate 3. A sleeve 9 is sleeved on the outside of the U-bolt body 1, and the sleeves 9 are symmetrically distributed. An X-shaped rod 10 is provided on the side of the sleeve 9, and a fixing plate 11 is provided on the outside of the X-shaped rod 10. A through hole 14 is provided inside the fixing plate 11, which facilitates the threaded rod 7 to pass through the interior of the fixing plate 11. The reinforcing plate 3 is slidably connected to the threaded rod 7 on its side. The threaded rod 7 passes through the through hole 14. The threaded rod 7 is externally connected to the wing nut 8. The threaded rod 7 is slidably connected to the outside of the reinforcing plate 3, and the sleeve 9 is sleeved on the outside of the U-bolt body 1. An X-shaped rod 10 and a fixing plate 11 are installed on the outside of the sleeve 9. After the reinforcing plate 3 is installed, the workers take out the reinforcing structure, sleeve the sleeve 9 on the outside of the U-bolt body 1, and threaded rod 7 passes through the fixing plate 11. Then, the external nut is tightened. The X-shaped rod 10 installed in this way can enhance the support on both sides and prevent loosening due to shrinkage.

[0031] On the other side of the reinforcing plate 3, there is an anti-slip plate 15. On the outer side of the anti-slip plate 15, there are rubber strips 16. The rubber strips 16 are evenly distributed. The anti-slip plate 15 has mounting holes 4 and limiting grooves 21 inside. The mounting holes 4 are inlaid with washers 19. The limiting grooves 21 are inlaid with limiting rings 20. The side of the washers 19 is provided with limiting rings 20. By installing the anti-slip plate 15 and rubber strips 16 on the outer side of the reinforcing plate 3, and installing the washers 19 inside the anti-slip plate 15, and the limiting rings 20 on the side of the washers 19, before using the reinforcing plate 3, the anti-slip structure is removed by the staff and installed on the outer side of the reinforcing plate 3. When the reinforcing plate 3 is pressed against the mounting surface by tightening the fastening structure, the friction can be increased, and the anti-slip effect is stronger during application.

[0032] The interior of the reinforcing plate 3 has a groove 5, and a slider 6 is embedded inside the groove 5. The side of the slider 6 is connected to a threaded rod 7. Because of the slider 6 and the groove 5, the threaded rod 7 can move quickly inside the reinforcing plate 3.

[0033] The side of the fixing plate 11 is provided with a positioning block 12, and the outer side of the reinforcing plate 3 is provided with a positioning groove 13. The positioning block 12 is embedded in the inside of the positioning groove 13. By installing the positioning block 12 and the positioning groove 13, it is convenient to make a preliminary connection between the reinforcing structure and the reinforcing plate 3.

[0034] A slot 18 is provided on the other side of the reinforcing plate 3, and an insert plate 17 is provided on the side of the anti-slip plate 15. The insert plate 17 is embedded in the slot 18. The installation of the insert plate 17 and the slot 18 facilitates the initial splicing of the reinforcing plate 3 and the anti-slip structure.

[0035] Mounting holes 4 are provided inside the reinforcing plate 3, and the U-bolt body 1 passes through the mounting holes 4. Because of the mounting holes 4, it is convenient for the U-bolt body 1 to pass through the interior of the reinforcing plate 3.

[0036] The working principle of the U-bolt with reinforcement structure is as follows: When applying the device, the U-bolt assembly first needs to be moved to the required installation position. Then, to enhance the friction between the reinforcing plate 3 and the mounting surface, an anti-slip plate 15 and a rubber strip 16 are installed on the outside of the reinforcing plate 3, and a washer 19 and a limiting ring 20 are installed inside the anti-slip plate 15. A slot 18 is opened on the side of the reinforcing plate 3, and an insert plate 17 is installed on the side of the anti-slip plate 15. Before using the reinforcing plate 3, the operator removes the anti-slip structure, first installing the washer 19 inside the anti-slip plate 15, and simultaneously installing the limiting ring 20 inside the limiting groove 21. Then, the insert plate 17 is installed in the slot 18. This allows the anti-slip structure to be installed on the outside of the reinforcing plate 3, increasing friction when it subsequently contacts the mounting surface. Secondly, to improve the performance of the U-bolt... To enhance strength, a groove 5 is created on the outer side of the reinforcing plate 3, and a slider 6 is embedded inside the groove 5. A threaded rod 7 is provided on the side of the slider 6, and a sleeve 9 is fitted onto the outside of the U-bolt body 1. An X-shaped rod 10 and a fixing plate 11 are installed on the outside of the sleeve 9. After the reinforcing plate 3 is installed, the workers remove the reinforcing structure, fit the sleeve 9 onto the outside of the U-bolt body 1, and simultaneously, the threaded rod 7 passes through the through hole 14 inside the fixing plate 11. The positioning block 12 on the side of the fixing plate 11 is then embedded in the positioning groove 13, and the external locking nut 2 is tightened. The X-shaped rod 10 installed in this way can enhance the support on both sides and prevent loosening due to shrinkage. It has a reinforced structure during use. Finally, when the anti-slip structure on the outside of the reinforcing plate 3 is severely worn, the fasteners are reversed, and a new anti-slip structure can be removed and reinstalled.

[0037] 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.
