Abstract
Description
Technical Field
[0001] This utility model relates to the field of fuel hose connection clamps that prevent collisions, scratches, and loosening. Specifically, it relates to a fuel hose connection clamp that prevents loosening. Background Technology
[0002] In the automotive industry, fuel hose couplings play a crucial role, as they securely connect fuel hoses to components such as the engine, ensuring the continuity and safety of fuel supply. Traditional couplings typically use bolts or three-pronged clamps; however, these couplings are complex in structure and large in size, often with protruding parts extending outwards after installation, occupying operating space and incurring high processing costs.
[0003] For example, the utility model patent (application number: 201721779765.5) discloses a "clamp," the description of which states that the clamp includes: a first clamp body, a second clamp body, a clamp bolt, a nut, and a sleeve; both ends of the first clamp body and both ends of the second clamp body are respectively provided with central through holes; the upper surface of the first clamp body is provided with a first groove that coincides with the center line of the two central through holes and matches the outer surface of the nut; the lower surface of the second clamp body is provided with a second groove that matches the outer surface of the sleeve at the position of the two central through holes. This utility model fastens the first and second clamp bodies by passing the clamp bolt through the central through holes at both ends of the first and second clamp bodies and using the nuts located in the first and second grooves. Then, the sleeve is placed on the nut in the second groove, thereby limiting the position of the nuts at both ends of the clamp bolt through the first groove, the second groove, and the sleeve, preventing the nuts from loosening or disengaging; the above patent can corroborate the defects of the prior art.
[0004] Therefore, we have made improvements and proposed a fuel hose connection clamp that prevents loosening. Utility Model Content
[0005] The purpose of this utility model is to solve the problem that the current clamp structure is complex and bulky.
[0006] To achieve the above-mentioned utility model objectives and improve the above-mentioned problems, this utility model provides a fuel hose connection clamp for preventing loosening, including an arc-shaped main spring, a first arc-shaped spring, and a second arc-shaped spring. The first arc-shaped spring is located in front of the second arc-shaped spring. The first arc-shaped spring and the second arc-shaped spring are respectively fixed to both ends of the arc-shaped main spring, and the arc-shaped main spring, the first arc-shaped spring, and the second arc-shaped spring form a ring.
[0007] As a preferred technical solution of this application, the arc-shaped main spring sheet is provided with a strip-shaped hole.
[0008] As a preferred technical solution of this application, the two ends of the strip hole are arc-shaped.
[0009] As a preferred technical solution of this application, there is a gap between the second arc-shaped spring piece and the first arc-shaped spring piece.
[0010] As a preferred technical solution of this application, the ends of the second arc-shaped spring piece and the first arc-shaped spring piece are not in contact with the main arc-shaped spring piece.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] In the scheme of this application:
[0013] 1. By using the No. 1 and No. 2 arc-shaped spring clips, the installation can be completed by wrapping the No. 1 and No. 2 arc-shaped spring clips around the outside of the fuel hose and using their elasticity to hold it tightly to the fuel hose. This method occupies little space, has high fastening strength, and low processing cost, solving the problem of complex clamp structure and large size in the existing technology.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0022] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0024] Example 1
[0025] Please refer to Figure 1 A fuel hose connection clamp designed to prevent loosening includes an arc-shaped main spring 1, an arc-shaped spring 21, and an arc-shaped spring 31. The arc-shaped spring 21 is located in front of the arc-shaped spring 31. The arc-shaped spring 21 and the arc-shaped spring 31 are fixed to the two ends of the arc-shaped main spring 1, respectively. The arc-shaped main spring 1, the arc-shaped spring 21, and the arc-shaped spring 31 are integrally formed and form a ring. By elastically gripping the fuel hose, the arc-shaped spring 31 and the arc-shaped spring 21 fit over the fuel hose, thus achieving installation. The structure is simple and the cost is low. The arc-shaped main spring 1, the arc-shaped spring 21, and the arc-shaped spring 31 are all made of SUS metal, which provides better clamping effect and more durable fastening strength.
[0026] Furthermore, such as Figure 1 As shown, the arc-shaped main spring 1 has a strip hole 41. The strip hole 41 is used to reduce the amount of material used, which helps to reduce costs.
[0027] Furthermore, such as Figure 1 As shown, the two ends of the strip hole 41 are arc-shaped. The arc shape can reduce stress concentration, disperse stress, and improve the durability of the spring sheet.
[0028] Furthermore, such as Figure 1As shown, there is a gap between the second arc-shaped spring piece 31 and the first arc-shaped spring piece 21.
[0029] Furthermore, such as Figure 1 As shown, the ends of the second arc-shaped spring 31 and the first arc-shaped spring 21 are not in contact with the main arc-shaped spring 1.
[0030] Example 2
[0031] The anti-loosening fuel hose connection clamp provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 3 and Figure 4 As shown, the two corners of the end of the first arc-shaped spring piece 21 are chamfered, and the two corners of the end of the second arc-shaped spring piece 31 are also chamfered. The chamfers are used to prevent the user from being stabbed or scratched.
[0032] Furthermore, such as Figure 1 As shown, the outer rear edge of the arc-shaped main spring 1 and the second arc-shaped spring 31 are both chamfered, and the outer front edge of the arc-shaped main spring 1 and the first arc-shaped spring 21 are also chamfered. The chamfers at the edges are used to prevent the edges from cutting the user.
[0033] Furthermore, such as Figure 1 As shown, a chamfer is provided at the rear corner of the connection between the arc-shaped main spring 1 and the first arc-shaped spring 21, and a chamfer is also provided at the front corner of the connection between the arc-shaped main spring 1 and the second arc-shaped spring 31.
[0034] Furthermore, such as Figure 4 As shown, there are two arc-shaped main spring pieces 1. The two arc-shaped main spring pieces 1 have the same fuel pipe 11 inside. Both ends of the fuel pipe 11 are provided with connectors 12.
[0035] The process of using the anti-loosening fuel hose connection clamp provided by this utility model is as follows:
[0036] When clamps are required, first place the arc-shaped main spring 1, the second arc-shaped spring 31 and the first arc-shaped spring 21 on the outside of the fuel pipe 11, and then insert the connector 12 into the inside of the fuel pipe 11. The fuel pipe 11 is then secured to the outside of the connector 12 by the elasticity of the arc-shaped main spring 1, the first arc-shaped spring 21 and the second arc-shaped spring 31. The clamps are installed at both ends of the fuel pipe 11 at a distance of 5mm+2 from the port.
