Description
Technical Field
[0001] The utility model relates to the technical field of clamps, in particular to a clamp for an engine which is not easy to loosen. Background Art
[0002] A durable engine clamp is primarily used to clamp and secure engine pipes or components, ensuring stability and safety during engine operation. Its ingenious structural design effectively secures engine components of varying sizes and maintains a secure clamping position even in complex engine vibration environments, effectively ensuring proper engine operation. It also offers convenient installation and removal features, improving work efficiency.
[0003] In practical applications, engine clamps that are not easy to loosen usually require the following technologies:
[0004] 1. Stable connection structure: By setting fixing pins on the two hoops and making them fit tightly with the high-precision mounting holes on the inner side of one end of the hoop, a stable initial structure is built;
[0005] 2. Reliable clamping force: mainly depends on high-quality bolts and matching threaded connections;
[0006] 3. Durable main structure material: Made of metal material with high strength, high hardness and good toughness.
[0007] Currently, various types of clamps are used to secure engine pipes or components during engine assembly and maintenance. Some clamps lack versatility; one type of clamp only fits engine components of a specific size. When components of different sizes are encountered, different types of clamps must be replaced, increasing costs and operational complexity. Other clamps are prone to loosening during engine operation due to insufficient clamping force or unstable connection structures in vibrating environments. Loose clamps can affect engine performance and may even cause safety accidents. Furthermore, the installation and removal of some clamps is cumbersome and time-consuming, reducing work efficiency.
[0008] However, there is a problem with the above-mentioned method, namely, the versatility, clamping reliability and working efficiency of the clamp in actual use are poor. Especially in equipment such as engines that have extremely high requirements for stability and safety, the existing clamps are difficult to meet the requirements of efficient and reliable fixing. In response to this problem, the present application proposes a solution and designs an engine clamp that is not easy to loosen. When in use, first place the first clamp on the engine component, use the fixing pin to fix the clamp ring, then insert the second clamp to adjust the position, and finally rotate the bolt to bring the mounting seat and the side support ear closer to clamp the component. This design enables the clamp to adapt to engine components of different sizes and improves versatility. The threaded connection between the bolt and the mounting seat ensures a reliable clamping force and is not easy to loosen. The structure is simple and easy to install and disassemble, which improves the reliability, safety and working efficiency of the engine and meets the actual use requirements of the engine clamp.

[0025] The embodiment of the present application effectively solves the technical problem that the versatility, clamping reliability and working efficiency of the clamp in actual use are poor by providing an engine clamp that is not easy to loosen, especially in equipment such as engines that have extremely high requirements for stability and safety, and the existing clamps are difficult to meet the requirements of efficient and reliable fixing.
[0026] Example
[0027] according to Figure 1 、 Figure 2 、 Figure 3 ,and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the versatility, clamping reliability and working efficiency of the clamp in actual use are poor, especially in equipment such as engines that have extremely high requirements for stability and safety. The existing clamps are difficult to meet the technical problems of efficient and reliable fixing requirements. The overall idea is as follows:
[0028] In response to the problems existing in the prior art, the utility model provides an engine clamp that is not easy to loosen, including a clamp strip 1, a clamp strip 2, two clamp rings 3 and two bolts 33. Both ends of the clamp strip 1 are fixedly installed with side support ears 11, and the side ends of the two side support ears 11 are provided with mounting seats 12. The inner sides of both ends of the clamp strip 1 are provided with mounting holes 14. Both ends of the clamp strip 2 are fixedly installed with side support ears 21, and the side ends of the two side support ears 21 are provided with mounting seats 2. 22, a fixing pin 31 is provided on each of the two hoop rings 3, and a built-in groove 32 is provided on the side ends of the two hoop rings 3. The two fixing pins 31 are fixedly connected to the corresponding mounting holes 14, wherein the hoop bar 2 is slidably mounted in the two built-in grooves 32, a through hole is provided on the mounting seat 12, and the through hole passes through the side end of the side support ear 11, a threaded hole is provided on the mounting seat 22, and the threaded hole passes through the side end of the side support ear 21, and two bolts 33 are provided on the inner side of the mounting seat 12, The two bolts 33 are threadedly connected to the corresponding mounting seats 22. First, the clamp strip 1 is placed on the engine pipe or component at the position where clamping is required. Since the fixing pins 31 on the two clamp rings 3 are fixedly connected to the mounting holes 14 on the inner sides of the two ends of the clamp strip 1, the position of the clamp strip 3 relative to the clamp strip 1 is fixed. Then, the clamp strip 2 is inserted between the built-in grooves 32 on the side ends of the two clamp rings 3. At this time, the clamp strip 2 can slide in the built-in grooves 32, which is convenient for adjusting the position to adapt to engine pipes or components of different sizes. After adjusting the position, the two bolts 33 are passed through the through holes on the mounting seat 12 on the side ends of the side support ear 11 so that they are aligned with the threaded holes on the mounting seat 22 on the side ends of the side support ear 21. By rotating the bolts 33, since the bolts 33 are threadedly connected to the mounting seat 22, as the bolts 33 are rotated, the bolts 33 will gradually move closer to the mounting seat 22, thereby making the mounting seat 12 and the side support ear 22 gradually close to each other, and finally achieving the clamping of the engine pipe or component.
[0029] The clamp's hoop strips 1, 2, 3 and bolts 33 are all made of high-strength stainless steel. The overall surface of the hoop strips 1, 2 and 3 is polished to improve the appearance quality and corrosion resistance. The connection parts of the clamp's hoop strips 1, 2, 3 and bolts 33 are all designed with rounded corners to reduce stress concentration and improve the overall strength and service life of the clamp. The inner side of the hoop strip 1 is provided with an anti-skid pattern 13, the inner side of the hoop strip 2 is provided with an anti-skid pattern 23, the inner wall of the built-in groove 32 is provided with a wear-resistant coating, and the two bolts are provided with a wear-resistant coating. The ends of 33 are all provided with hexagonal notches. Hoop strip 1 serves as the main body of the clamp, providing a basic frame structure for the entire clamp. The design of anti-slip pattern 13 and anti-slip pattern 2 23 enables the clamp to have a stable force point when clamping. When the bolt 33 is gradually tightened through the threaded connection with the mounting seat 2 22, the mounting seat 12 and the side support ear 2 21 gradually approach each other, and the hoop strip 1 and the hoop strip 2 work together to clamp the pipes or components of the engine from both sides. At the same time, the hoop ring 3 is fixedly connected to the mounting hole 14 through the fixing pin 31, providing support and stability for the entire clamp.
[0030] Working principle:
[0031] The first step is to place the clamp 1 on the engine pipe or component that needs to be clamped when using the engine clamp that is not easy to loosen. Since the fixing pins 31 on the two hoop rings 3 are fixedly connected to the mounting holes 14 on the inner sides of the two ends of the hoop ring 1, the position of the hoop ring 3 relative to the hoop 1 is fixed. Then, insert the hoop 2 between the built-in grooves 32 on the side ends of the two hoop rings 3. At this time, the hoop 2 can slide in the built-in grooves 32, which is convenient for adjusting the position to adapt to engine pipes or components of different sizes. After adjusting the position, pass the two bolts 33 through the through holes on the mounting seat 12 on the side end of the side support ear 11 so that it is aligned with the mounting seat on the side end of the side support ear 21. The threaded holes on the second mounting base 22 are aligned, and by rotating the bolt 33, since the bolt 33 is threadedly connected to the mounting base 22, as the bolt 33 rotates, the bolt 33 will gradually approach the mounting base 22, thereby gradually approaching the mounting base 12 and the side support ear 21, and finally achieving clamping of the engine pipe or component. By designing the clamp to be able to adapt to engine components of different sizes, the versatility of the clamp is improved. At the same time, the threaded connection between the bolt 33 and the mounting base 22 provides a reliable clamping force, which is not easy to loosen during engine vibration and operation, thereby improving the reliability and safety of the engine. In addition, the clamp has a simple structure, is easy to install and disassemble, and improves work efficiency.
[0032] The second step is that during the operation of the clamp, the various components work together. The hoop strip 1 serves as the main body of the clamp, providing a basic frame structure for the entire clamp. The design of the anti-slip groove 13 and the anti-slip groove 23 ensures that the clamp has a stable force point when clamping. When the bolt 33 is gradually tightened through the threaded connection with the mounting seat 22, the mounting seat 12 and the side support ear 21 gradually approach each other, and the hoop strip 1 and the hoop strip 2 work together to clamp the engine pipe or component from both sides. At the same time, the hoop ring 3 is fixedly connected to the mounting hole 14 through the fixing pin 31, providing support and stability for the entire clamp. By designing the clamp so that the various components work together, the clamp can better adapt to the complex working environment of the engine, maintain a stable clamping state under harsh conditions such as high temperature, high pressure and strong vibration, and ensure that the engine components are firmly and reliably connected. The cooperative working principle also increases the service life of the clamp and reduces the wear and damage of individual components. In addition, the clamping force is more evenly distributed, avoiding the situation where the pipe or component is damaged due to excessive local pressure, thereby protecting the key components of the engine.
[0033] Finally, it should be noted that the above embodiments are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
