Description

Technical Field

[0001] This utility model relates to the field of elastic clamp technology, and in particular to a durable steel strip elastic clamp. Background Technology

[0002] The main function of steel strip elastic clamps is to connect and fix various pipe fittings, ensuring the stability and sealing of pipelines and preventing liquid or gas leakage. They are widely used in the connection and fastening of hoses, rigid pipes, and other fittings in the automotive, machinery, and other fields, especially in automotive engine cooling systems, fuel systems, braking systems, and some industrial piping systems.

[0003] The steel band elastic clamp consists of an elastic band ring and two clamping ears on the outer ring of the band ring. During use, an installation tool is used to clamp the clamping ears together, bringing them close together. This enlarges the collar formed by the band ring, allowing the connection point to pass through it. Then, the clamping ears are released, and the elasticity of the band ring returns the collar to its original size, completing the assembly. However, during this assembly process, the lack of a limiting component between the clamping ears to indicate the reached preset clamping force makes it easy to over-tighten the clamp, causing damage. Furthermore, current steel band clamps lack corrosion resistance, making them unsuitable for applications requiring corrosion resistance. Some band rings have coatings, but friction during assembly can easily wear down the coating, leading to corrosion at the worn areas. To address these issues, a steel band elastic clamp is designed. Utility Model Content

[0004] In view of the above-mentioned technical problems, this utility model provides a durable steel band elastic clamp, which reduces the friction between the clamp bodies during adjustment, and adds a limiting protrusion to prevent damage to the clamp due to excessive force when adjusting the two clamping ears. In addition, a zinc-aluminum coating is applied to the outer surface of the clamp body to make it corrosion resistant.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A durable steel band elastic clamp is characterized by comprising a clamp body and a first clamping ear and a second clamping ear disposed at both ends of the clamp body. An adjustment hole is provided on the clamp body near the end of the first clamping ear. The second clamping ear passes through the adjustment hole and extends outward, forming a loop with the clamp body. Anti-abrasion pads are provided on both sides of the adjustment hole and on the side wall of the clamp body where the adjustment hole passes through. A protruding block is provided on the inner side of the first clamping ear.

[0007] Furthermore, the second clamping ear is positioned opposite to the first clamping ear.

[0008] Furthermore, the anti-abrasion sticker on the side wall of the portion of the band body that passes through the adjustment hole is in contact with the anti-abrasion sticker on the wall of the adjustment hole.

[0009] Furthermore, the outer surface of the clamp body is coated with a zinc-aluminum coating, which forms a corrosion-resistant protective film on the surface of the steel clamp body, making the clamp corrosion-resistant.

[0010] Furthermore, the main body of the hoop is provided with at least one weight-reducing hole, and the weight-reducing holes are distributed circumferentially along the loop formed by the hoop body.

[0011] The beneficial effects of this utility model are:

[0012] The elastic clamp designed in this utility model has anti-wear pads on both sides of the adjustment hole on the clamp body and on the side wall of the part of the elastic clamp body that passes through the adjustment hole. This effectively reduces the friction between the part of the clamp body that passes through the adjustment hole and the hole wall of the adjustment hole during the assembly process, avoids damage to the clamp due to friction, and extends its service life.

[0013] This utility model has a limiting protrusion between the first clamping ear and the second clamping ear, which are arranged opposite to each other at both ends on the main body of the hoop. The protrusion prevents the distance between the two clamping ears from being too large, thereby reducing the problem of damage to the hoop caused by excessive force during assembly.

[0014] This invention provides a zinc-aluminum coating on the outside of the clamp body, forming a corrosion-resistant protective film on the surface of the steel clamp body, thus making the clamp corrosion-resistant. Attached Figure Description

[0020] Example 1

[0021] As shown in the figure, an adjustment hole 11 is provided on the end of the clamp body 1 near the first clamping ear 2. The second clamping ear 3 passes through the adjustment hole 11 and extends out, forming a collar on the clamp body 1. The clamp body 1 also has at least one weight-reducing hole 12, which is distributed circumferentially along the collar formed by the clamp body 1. The second clamping ear 3 is arranged opposite to the first clamping ear 2. A protrusion 4 is provided on the inner side of the first clamping ear 2 to prevent the distance between the two clamping ears from being too large, thereby reducing the problem of clamp damage caused by excessive force during assembly.

[0022] Anti-abrasion pads 5 are provided on both sides of the adjusting hole 11 and on the side wall of the portion of the clamp body 1 that passes through the adjusting hole 11.

This effectively reduces friction between the portion of the clamp body 1 that passes through the adjusting hole 11 and the hole wall of the adjusting hole 11 during clamp assembly, preventing damage to the clamp due to friction and extending its service life.

[0023] Furthermore, a zinc-aluminum coating is provided on the outside of the clamp body 1, so that a corrosion-resistant protective film is formed on the surface of the steel clamp body 1, making the clamp corrosion-resistant.
