Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, specifically to an air spring clamping device that facilitates uniform pressure. Background Technology

[0002] In many fields such as modern industry and transportation, air springs are widely used in various equipment and vehicles to provide important functions such as cushioning, shock absorption and support. However, in the process of using air springs, reliable fixation and ensuring uniform force distribution are crucial issues, and traditional air spring clamping devices have many shortcomings in this regard.

[0003] Traditional air spring clamping devices are often simple in structure and lack effective means of controlling the pressure of the air spring. These devices usually rely on simple rigid structures for support and fixation to withstand the impact forces on the air spring, lacking an effective buffering mechanism.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution: an air spring clamping device for facilitating uniform pressure, comprising: a fixed shell 1; a mounting component 3, the bottom of which is fixedly connected to the top of the fixed shell 1, the mounting component 3 being used to connect the fixed shell 1 via a plug-in connection; and a limiting component 2, the top of which is fixedly connected to the inner wall of the top of the fixed shell 1, the limiting component 2 being used to buffer the impact force on the air spring using compressed air; the limiting component 2 includes an air shell 21, each air shell 21 forming an independent air chamber, and pre-filled with a certain amount of gas. The gas plays an important role in pressure regulation and energy absorption during the operation of the device. The gas shell 21 is arranged in a ring array along the central axis of the fixed shell 1. The top of the gas shell 21 is fixedly connected to the connecting pipe 24 through the gas guide pipe 23, and the bottom of the gas guide pipe 23 is fixedly connected to the top of the gas shell 21. The inner wall of the gas shell 21 is slidably connected to the piston column 22. The outer wall of the piston column 22 is fixedly connected to the pressure plate 26 through the connecting plate 25, and the outer wall of the connecting plate 25 is fixedly connected to the outer wall of the piston column 22. The bottom outer wall of the connecting plate 25 is fixedly connected to the limiting arc plate 28.

[0026] The end of the air guide pipe 23 away from the gas shell 21 is fixedly connected to the outer wall of the connecting pipe 24. The side of the connecting plate 25 away from the piston column 22 is fixedly connected to the outer wall of the pressure plate 26. A top spring 27 is fixedly connected to the outer wall of the top of the pressure plate 26. The side of the top spring 27 away from the pressure plate 26 is fixedly connected to the inner wall of the top of the fixed shell 1. The inner wall of the top of the fixed shell 1 is fixedly connected to the top of the gas shell 21. The outer wall of the air guide pipe 23 is fixedly connected to the inner wall of the top of the fixed shell 1. Some of the gas in the gas shell 21 will be transported to the diagonal gas shell 21 through the air guide pipe 23, which will increase the amount of gas in the diagonal gas shell 21, thereby pushing the piston column 22 in the diagonal gas shell 21 to move downward, so that the piston column 22 of the diagonal gas shell 21 presses against the air spring. This can alleviate the pressure on the piston column 22 at the force-bearing gas shell 21 to a certain extent, and realize the distribution and balance of pressure.

[0027] Mounting assembly 3 includes a disc 32, with a mounting block 33 fixedly connected to the top of the disc 32. A mounting shell 34 is inserted into the outer wall of the mounting block 33 via a mounting groove 38, which is located in the bottom wall of the mounting shell 34. Insert plates 36 are inserted into the inner walls on both sides of the mounting shell 34. Honeycomb pillars 37 are fixedly connected to the inner walls of the insert plates 36 and are arranged in a linear array along the outer walls of the insert plates 36. Fixing pillars 31 are fixedly connected to the bottom of the disc 32 and are arranged in a ring array along the central axis of the disc 32. The outer walls of both sides of the mounting shell 34 are fixedly connected with locking blocks 35, which are connected by a snap-fit ​​method. This connection method is based on the mechanical interlock principle, which can prevent the insert plate 36 from accidentally coming out during the operation of the device, ensuring the integrity and reliability of the entire connection structure. The outer wall of the locking block 35 is snapped into the outer wall of the insert plate 36, the outer wall of the honeycomb column 37 is inserted into the inner wall of the mounting block 33, the outer wall of the honeycomb column 37 is inserted into the inner wall of the mounting shell 34, and the end of the fixing column 31 away from the disc 32 is fixedly connected to the top of the fixing shell 1.

[0028] The basic structure of the device is the fixed shell 1, which serves as the supporting frame for the entire seizure device, providing stable support for all components of the device and ensuring its normal operation.

[0029] The mounting assembly 3 is located on top of the fixed housing 1. Its main function is to connect with the mounting parts of external equipment or air springs to ensure the overall installation and fixation of the device. In the mounting assembly 3, the disc 32 is the core component. Multiple fixing posts 31 are arranged in a ring array at the bottom of the disc 32. One end of these fixing posts 31 is connected to the disc 32, and the other end is firmly fixed to the top of the fixed housing 1, providing reliable support and connection for the mounting assembly 3. The mounting block 33 on the top of the disc 32 is an important component for connecting the mounting housing 34. The mounting housing 34 is inserted into the mounting block 33 through the mounting groove 38 at the bottom to achieve initial positioning.

[0030] Insert plates 36 are inserted into the inner walls on both sides of the mounting shell 34. Honeycomb columns 37, fixedly connected to the inner walls of the insert plates 36, are arranged in a linear array along their outer walls. This structure has unique mechanical advantages, possessing not only high strength and stability but also a certain degree of elastic buffering performance. The honeycomb columns 37 play a crucial role in the connection between the mounting block 33 and the mounting shell 34. They are inserted into the inner walls of both the mounting block 33 and the mounting shell 34, forming a multi-dimensional connection. From a static perspective, this connection method, based on multi-point support and interlocking principles, ensures a tight and stable connection between the mounting shell 34 and the mounting block 33. On one hand, the honeycomb columns 37 provide support to the mounting shell 34 in multiple directions, evenly distributing the force borne by the mounting shell 34 and greatly enhancing the stability of the entire structure. On the other hand, the elastic buffering performance of the honeycomb columns 37 allows them to undergo slight deformation when subjected to external forces. This deformation absorbs some energy, avoiding stress concentration caused by rigid connections, thereby improving the adaptability of the device under different working conditions.

[0031] In addition, the locking blocks 35 on both sides of the outer wall of the mounting housing 34 are connected to the outer wall of the insert plate 36 by a snap-fit ​​method. This connection method is based on the mechanical interlock principle, which can prevent the insert plate 36 from accidentally coming out during the operation of the device, ensuring the integrity and reliability of the entire connection structure. Through this structure that combines plug-in and snap-fit, the mounting component 3 can be easily and quickly connected to external parts, which helps to apply uniform pressure to the air spring.

[0032] The limiting component 2 is mainly responsible for buffering the impact force on the air spring to ensure that the pressure it bears is evenly distributed. The core structure of the limiting component 2 includes air shells 21. These air shells 21 are arranged in a ring array along the central axis of the fixed shell 1 on the top inner wall of the fixed shell 1. Each air shell 21 forms an independent air chamber and is pre-filled with a certain amount of gas. This gas plays an important role in pressure regulation and energy absorption during the operation of the device. The air shells 21 are fixedly connected to the connecting pipe 24 through the air guide pipe 23. The air guide pipe 23 not only connects the air shells 21 and the connecting pipe 24, but its outer wall is also fixedly connected to the top inner wall of the fixed shell 1, which further enhances the stability of the entire structure.

[0033] A piston rod 22 is slidably connected inside the air shell 21. The piston rod 22 is connected to the pressure plate 26 through the connecting plate 25. When the air spring is impacted by an external force, the piston rod 22 will slide inside the air shell 21. During this process, the gas inside the air shell 21 will be compressed. According to the principle of gas compressibility, the gas volume decreases and the pressure increases, thereby buffering the impact force. Moreover, during this process, some of the gas in the air shell 21 will be transported to the diagonal air shell 21 through the air guide pipe 23, causing the amount of gas in the diagonal air shell 21 to increase. This will push the piston rod 22 in the diagonal air shell 21 to move downward, so that the piston rod 22 of the diagonal air shell 21 presses against the air spring. This can alleviate the pressure on the piston rod 22 at the impacted air shell 21 to a certain extent, and achieve pressure distribution and balance.

[0034] The limiting arc plate 28, which is fixedly connected to the bottom outer wall of the connecting plate 25, contacts the surface of the air spring to limit its position and prevent excessive displacement. At the same time, the top spring 27, which is fixedly connected to the top outer wall of the pressure plate 26, has its other end fixedly connected to the top inner wall of the fixed shell 1. When the air spring is subjected to an impact force, the impact force is transmitted to the pressure plate 26, causing the top spring 27 to be compressed and generate and store elastic potential energy. When the impact force weakens, the top spring 27 releases the stored elastic potential energy, pushing the pressure plate 26 and the piston column 22 to reset. Throughout the process, the presence of the top spring 27 not only further buffers the impact force but also assists the pressure plate 26 and the limiting arc plate 28 in continuously applying appropriate pressure to the air spring, ensuring that the pressure on the air spring is uniform and avoiding damage to the air spring due to excessive local pressure, thus ensuring the stable operation of the air spring under various working conditions.
