Description

Technical Field

[0001] The utility model belongs to the technical field of U-shaped bolts, in particular to a rear U-shaped bolt for a light truck. Background Art

[0002] U-bolt is a special fastener named because of its shape like the letter "U". U-bolt is used to connect the axle and the leaf spring. Usually two U-bolts are used to fix the leaf spring on the suspension to the axle. The design of U-bolt enables it to withstand tension and compression while providing a stable fixing effect.

[0003] For example, a U-shaped bolt with publication number CN213808406U includes an intermediate rod and two arms, the two arms are respectively connected to the two ends of the intermediate rod so that the whole is U-shaped, the two arms are arranged in parallel and the ends of the two arms are threaded sections, the bottom wall of the intermediate rod is a plane, the inner walls of the two arms are planes, the bottom wall of the intermediate rod is vulcanized and fixed with a rubber layer 1, the inner walls of the two arms are vulcanized and fixed with a rubber layer 2, the thickness of the rubber layer 1 is greater than the thickness of the rubber layer 2 and the rubber layer 1 and the rubber layer 2 are connected as one body, the end of the threaded section has a coaxially arranged plug hole, the threaded section has a plurality of open grooves extending axially to the end and radially penetrating to the plug hole, and a fastener is connected in the plug hole. The utility model has the advantages of good support effect, good buffering and vibration reduction, and good safety in use;

[0004] When the U-bolt is connected, a nut and a washer are required. However, the simple connection method of the nut and the washer is prone to loosening after long-term use, thereby causing the leaf spring to fall off. In order to solve the above problem, a light truck rear U-bolt is proposed. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems and provide a light truck rear U-bolt, comprising:

[0006] The U-shaped bolt body has threaded parts at both lower ends, grooves are provided at both front and rear sides of the threaded parts, and a connecting part is provided at the upper end of the U-shaped bolt body;

[0007] The gasket is sleeved on the outer wall of the threaded portion, and both sides of the inner wall of the gasket are integrally provided with limit blocks.

[0008] Through the above technical solution, when the U-bolt is fixed, since a limiting block is provided on the inner wall of the gasket, when the U-bolt vibrates, the gasket is fixed to the outer wall of the bolt part through the limiting block, thereby preventing the gasket from rotating during use, thereby improving the stability of the U-bolt.

[0009] In a preferred embodiment, the connecting portion is a horizontal structure.

[0010] Through the above technical solution, the connecting part is a horizontal structure, which increases the contact surface of the product after loading and improves the stability of the product during use.

[0011] In a preferred embodiment, a threaded rod is threadedly connected to one side of the connection portion, and a top plate is fixedly mounted on the end of the threaded rod.

[0012] Through the above technical solution, for different leaf springs, the bolt rod is rotated to drive the top plate to move along the connecting portion, so that the U-shaped bolt can fix different leaf springs.

[0013] In a preferred embodiment, the outer wall of the connecting portion is provided with a groove matched with the top plate.

[0014] In a preferred embodiment, the U-bolt body is made of stainless steel.

[0015] In a preferred embodiment, the outer wall of one end of the threaded rod is provided with friction lines.

[0016] Through the above technical solution, the friction pattern is provided to facilitate the rotation of the threaded rod.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are as follows: the utility model provides a light truck rear U-bolt.

[0018] 1. When the U-bolt is fixed, since the inner wall of the gasket is provided with a limit block, when the U-bolt vibrates, the gasket is fixed to the outer wall of the bolt part through the limit block, thereby preventing the gasket from rotating during use, thereby improving the stability of the U-bolt.

[0019] 2. For different leaf springs, the bolt rod is rotated to drive the top plate to move along the connecting portion, so that the U-bolt can fix different leaf springs. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The following will be combined Figure 1-3 A light truck rear U-bolt according to an embodiment of the utility model is described in detail.

[0026] Example:

[0027] A light truck rear U-bolt, comprising:

[0028] The U-shaped bolt body 1 has threaded parts 11 at the lower ends on both sides. The U-shaped bolt body 1 is made of stainless steel. Grooves 12 are provided on both sides of the threaded part 11. A connecting part 13 is provided at the upper end of the U-shaped bolt body 1. The connecting part 13 is a horizontal structure, which increases the contact surface of the product after loading and improves the stability of the product during use.

[0029] A threaded rod 3 is threadedly connected to one side of the connection part 13, and a friction pattern is provided on the outer wall of one end of the threaded rod 3, which facilitates the rotation of the threaded rod 3. A top plate 31 is fixedly installed on the end of the threaded rod 3, and a groove matching the top plate 31 is provided on the outer wall of the connection part 13. For different leaf springs, the bolt rod 3 is rotated to drive the top plate 31 to move along the connection part 13, so that the U-bolt can fix different leaf springs.

[0030] The gasket 2 is sleeved on the outer wall of the threaded portion 11, and limiting blocks 21 are integrally arranged on both sides of the inner wall of the gasket 2. When the U-bolt is fixed, since the limiting blocks 21 are arranged on the inner wall of the gasket 2, when the U-bolt vibrates, the gasket 2 is fixed to the outer wall of the bolt portion 11 through the limiting blocks 21, thereby preventing the gasket 2 from rotating during use, thereby improving the stability of the U-bolt.

[0031] Working principle:

[0032] When the U-bolt is fixed, since the inner wall of the gasket 2 is provided with a limit block 21, when the U-bolt vibrates, the gasket 2 is fixed to the outer wall of the bolt portion 11 by the limit block 21, thereby preventing the gasket 2 from rotating during use, thereby improving the stability of the U-bolt.
