Description

Technical Field

[0001] The utility model relates to the field of clamps, in particular to an ear piece and a spring strong clamp using the ear piece. Background Art

[0002] Designed specifically for medium and large trucks, the powerful hose clamp is an efficient and reliable hose connection solution. Made of high-quality materials, the powerful hose clamp can connect the hose to the hard pipe, preventing the hose from loosening or falling off in high-pressure and high-vibration environments, ensuring the normal operation of the truck's hydraulic, fuel, cooling and other systems.

[0003] The existing strong hose clamp is made of a steel belt rolled into a circle, and the two ends of the steel belt are coiled outward to form double bent ear rings. There is a space between the two ear rings, and an arc-shaped bridge plate is needed to overlap them to form a complete circle. The tower bridge design makes the overall sealing of the clamp poor. With the shaking and vibration of the car body, the torque will be loosened, affecting the sealing of the clamp. The torque needs to be tightened again to obtain the sealing effect. Utility Model Content

[0004] In order to solve at least one of the above-mentioned defects, according to one aspect of the present invention, an ear piece is provided, comprising: a clamp body; two ear piece bodies, one end of which is installed on the clamp body and is symmetrically arranged, and the other end is bent outward and curled and installed on the surface of the ear piece body.

[0005] The ear body includes: a connection hole, which is opened on the ear body and is used to provide a connection space.

[0006] According to another aspect of the present invention, a spring strong clamp is provided, comprising any one of the above-mentioned ear pieces.

[0007] It also includes: a nut shaft installed in one of the ear pieces; a through-hole shaft installed in the other ear piece; a flange cap screw, with both ends passing through the nut shaft and the through-hole shaft respectively, and the flange cap screw is configured to drive the nut shaft to move closer to or away from the through-hole shaft when rotating in the through-hole shaft.

[0008] It also includes: a T-shaped screw sleeve, which is installed on the through-hole shaft, and the flange cap screw passes through the T-shaped screw sleeve; a spring, which is sleeved on the flange cap screw, one end of the spring is connected to the T-shaped screw sleeve, and the other end of the spring is connected to the flange cap screw.

[0009] It also includes: an anti-slip component, which is installed on the flange cap screw and is used to prevent the flange cap screw from falling off from the through-hole shaft.

[0010] The number of the clamp body is set to be single, and one end of the clamp body is rolled and overlapped toward the other end, and the two ear pieces are respectively arranged at both ends of the clamp body.

[0011] The number of the clamp bodies is also set to two, both of which are arc-shaped, and the two ends of the two clamp bodies are overlapped, and two ear pieces are provided on the two clamp bodies.

[0012] Both sides of the clamp body are formed with warped edges, which are used to prevent the sides of the clamp body from cutting the hose.

[0013] The utility model provides an ear piece and a spring-loaded clamp using the ear piece. Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. By adopting the design of the whole steel ring with high pressure, curled and overlapping edges, the clamp body does not need additional arc bridge plates for overlapping when forming a full circle, which significantly improves the overall sealing of the clamp. The curled edges are formed on both sides of the clamp body, which not only enhances the structural strength of the clamp, but also effectively prevents the side of the clamp body from cutting the hose, further ensuring the sealing effect.

[0015] 2. The ear body adopts a thickened design, which is stronger and can withstand greater tension and pressure, thereby enhancing the stability and fastening force of the clamp. By adopting a compression spring torque compensation fastening structure, the compression spring torque will offset the relaxation of the steel belt ring in the environment of vehicle body shaking and vibration. Especially in low or high temperature environments, the spring torque can greatly offset the slight changes in the contraction or expansion of the steel belt ring, ensuring that the clamp always remains in a closed state without the need to tighten the torque again.

[0029] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of protection of the present invention.

[0030] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention.

[0031] Example 1

[0032] Reference Figure 1 and Figure 4 According to one aspect of the present invention, an ear piece is provided, comprising: a clamp body 1; two ear pieces 2, one end of which is mounted on the clamp body 1 and is symmetrically arranged, and the other end is bent outward and curled and mounted on the surface of the ear piece body 2. The ear piece body 2 adopts a thickened design, so that the overall tensile strength of the clamp ring reaches 10000N, and the strength is higher.

[0033] The ear body 2 includes a connection hole 201 , which is formed on the ear body 2 and is used to provide a connection space.

[0034] Example 2

[0035] Reference Figure 1-Figure 3 According to another aspect of the present invention, a spring strong clamp is provided, comprising any one of the above-mentioned ear pieces.

[0036] It also includes: a nut shaft 3, installed in one of the ear bodies 2; a through-hole shaft 6, installed in the other ear body 2; a flange cap screw 4, with both ends passing through the nut shaft 3 and the through-hole shaft 6 respectively, and the flange cap screw 4 is configured to drive the nut shaft 3 towards or away from the through-hole shaft 6 when rotating in the through-hole shaft 6.

[0037] The T-screw sleeve 601 is installed on the through-hole shaft 6, and the flange nut screw 4 passes through the T-screw sleeve 601; the spring 5 is sleeved on the flange nut screw 4, one end of the spring 5 is connected to the T-screw sleeve 601, and the other end of the spring 5 is connected to the flange nut screw 4; the anti-slip component 401 is installed on the flange nut screw 4, and is used to prevent the flange nut screw 4 from falling off from the through-hole shaft 6. A compression spring torque compensation fastening structure is adopted. In an environment where the vehicle body shakes and vibrates, the compression spring torque will offset the relaxation of the steel belt ring, especially in a low or high temperature environment, the spring torque can greatly offset the slight changes in the contraction or expansion of the steel belt ring, so that the steel belt ring remains in a sealed state and does not return. Considering that the clamp needs to be disassembled from the flange nut screw 4 for installation under certain circumstances, in order to prevent the flange nut screw 4 from falling off and affecting use, the anti-slip component 401 can prevent it from falling off.

[0038] The number of clamp bodies 1 is set to be single, and one end of the clamp body 1 is rolled and overlapped to the other end. The two ear bodies 2 are respectively arranged at both ends of the clamp body 1. The clamp body 1 adopts a design of a whole steel ring pressed high, curled and overlapped, eliminating the original tower bridge design, and the overall sealing is stronger.

[0039] Both sides of the clamp body 1 are formed with warped edges to prevent the sides of the clamp body 1 from cutting the hose.

[0040] Example 3

[0041] Reference Figure 5 and Figure 6 The difference between this embodiment and the second embodiment is that the number of the clamp bodies 1 is set to two, both of which are arc-shaped, and the two ends of the two clamp bodies 1 are overlapped, and two ear bodies 2 are provided on the two clamp bodies 1. The two clamp bodies 1 improve the flexibility and adaptability of the clamp, so that it can better fit hoses of different shapes.

[0042] During use, the two ear bodies 2 are welded to the clamp body 1, the nut shaft 3 is installed in one of the ear bodies 2, the through-hole shaft 6 is installed in the other ear body 2, the flange cap screw 4 is passed through the nut shaft 3 and the through-hole shaft 6, the T-screw sleeve 601 is installed on the through-hole shaft 6, and the flange cap screw 4 is passed through the T-screw sleeve 601. Ensure that one end of the spring 5 is connected to the T-screw sleeve 601 and the other end is connected to the flange cap screw 4. The anti-slip part 401 ensures that the flange cap screw 4 will not fall off when it needs to be disassembled for installation or maintenance. By rotating the flange cap screw 4, the tightening force of the clamp is adjusted. During the adjustment process, the compression spring torque will offset the loosening of the steel belt ring to ensure that the clamp always remains in a closed state.

[0043] In summary, compared with the existing technology, it has the following beneficial effects:

[0044] By adopting a design of a whole steel ring with high-pressure, curled and overlapping edges, the clamp body 1 does not need an additional arc bridge plate for overlapping when forming a full circle, which significantly improves the overall sealing of the clamp. Curved edges are formed on both sides of the clamp body 1, which not only enhances the structural strength of the clamp, but also effectively prevents the side of the clamp body 1 from cutting the hose, further ensuring the sealing effect.

[0045] The ear body 2 adopts a thickened design, which is stronger and can withstand greater tension and pressure, thereby enhancing the stability and tightening force of the clamp. By adopting a compression spring torque compensation fastening structure, in an environment where the vehicle body shakes and vibrates, the compression spring torque will offset the relaxation of the steel belt ring. Especially in low or high temperature environments, the spring torque can greatly offset the slight changes in the contraction or expansion of the steel belt ring, ensuring that the clamp always remains in a closed state without the need to tighten the torque again.
