Description

Cushioning cushion Technical Field

[0001] This utility model relates to the field of shock absorption technology, and in particular to a cushioning type spring pad. Background Technology

[0002] In modern industrial production, the vibration and impact problems generated by mechanical equipment during operation are becoming increasingly prominent. These vibrations and impacts not only interfere with the stable operation of the equipment, reduce processing accuracy, and lead to a decline in product quality, but also subject equipment parts to additional stress, accelerate wear and fatigue, and significantly shorten the service life of the equipment. To effectively solve these problems and ensure the normal operation of equipment, cushioning pads have emerged. With their unique structure and materials, they can absorb and disperse the vibration and impact forces during mechanical operation, becoming a key component for improving equipment performance and reliability.

[0003] Buffer-type elastic pads achieve buffering by absorbing and dissipating mechanical energy through elastic deformation. When subjected to external impact, they undergo elastic deformation, converting the external force energy into stored elastic potential energy. During the deformation and recovery process, hysteresis occurs due to internal friction and intermolecular interactions within the material. The force and displacement relationship during loading and unloading forms a hysteresis loop. Loading absorbs more energy than unloading releases energy, and the excess energy is dissipated in the form of heat, thereby achieving the buffering and shock absorption effect.

[0004] Currently, cushioning pads do play a positive role in vibration reduction in various industries, and are widely used in machinery, transportation, construction and other fields to effectively reduce the damage caused by vibration and impact. However, as the pads bear pressure for a long time, they undergo repeated deformation, and their internal structure will gradually be damaged. When the elastic deformation accumulates excessively, it will turn into irreversible plastic deformation, causing the shape and performance of the pads to change permanently and making it impossible to restore the initial elastic state. As a result, the pads lose their cushioning and vibration reduction function, affecting the normal operation and service life of the equipment. Therefore, cushioning pads are proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above deficiencies, this utility model provides a buffer-type elastic pad, which aims to improve the problem of excessive accumulation of elastic deformation in the existing elastic pad, which transforms into irreversible plastic deformation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cushioning pad includes a housing, four sliding pillars fixedly connected inside the housing, four limiting pillars fixedly connected inside the housing, springs sleeved on the outer walls of the four limiting pillars, two heat insulation layers provided inside the housing, a rubber layer fixedly connected to the side of the two heat insulation layers that are close to each other, and a telescopic component fixedly connected to the outer wall of the housing.

[0008] As a further description of the above technical solution:

[0009] The telescopic component includes multiple protrusions, the outer walls of which are fixedly connected to the outer wall of the housing. The outer wall of the housing has multiple grooves, and both sides of the housing have multiple through holes.

[0010] As a further description of the above technical solution:

[0011] The cross-sectional shape of the limiting post is U-shaped, and the outer walls of the four sliding posts are slidably connected to the inner walls of the four limiting posts respectively.

[0012] As a further description of the above technical solution:

[0013] Both sides of the spring are fixedly connected to the inside of the housing, and expansion joints are provided on both sides of the housing;

[0014] As a further description of the above technical solution:

[0015] The outer wall of the spring is in contact with one side of the heat insulation layer, and the outer wall of the spring is in contact with one side of the rubber layer;

[0016] As a further description of the above technical solution:

[0017] The heat insulation layer is made of heat insulation material, and the rubber layer is made of rubber material;

[0018] As a further description of the above technical solution:

[0019] The shell has a rectangular cross-sectional shape, and the through hole is circular.

[0020] As a further description of the above technical solution:

[0021] The cross-section of the protrusion is circular, and the cross-section of the expansion joint is rectangular.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when an external force is applied to the shell, due to the material properties, it will be squeezed and deformed inward. During this process, the outer wall of the sliding column slides relative to the inner wall of the limiting column, while applying pressure to the internal spring, forcing the spring to deform and store elastic potential energy. As the external force disappears, the elastic potential energy accumulated by the spring is released instantly, and the strong elastic force pushes the shell to quickly return to its initial state. At the same time, under the action of the spring, the sliding column slides in the opposite direction along the inner wall of the limiting column, so that the positional relationship between the sliding column and the limiting column is also restored to its original state. The entire structure completes a buffer reset process, ready to meet the next external impact, and continues to play its buffer and shock absorption function.

[0024] 2. In this utility model, when the shell is subjected to external pressure, the expansion joints, grooves, and protrusions on its surface work together to play a key role. The expansion joints can stretch under force, and the grooves and protrusions work together to deform, which together greatly increases the elastic threshold of the shell and effectively alleviates the impact of external force. At the same time, the through holes on the shell can timely discharge the gas generated by the pressure inside during the extrusion process, avoiding damage to the shell due to excessive internal gas pressure. In addition, the heat insulation layer tightly wraps the shell, isolating the heat generated by extrusion to the outside and preventing high temperature from damaging the internal precision structure. Through the cooperation of these structures, the shell can not only effectively cope with the impact of external force, but also reduce the risk of physical and thermal damage, and significantly extend its service life.

[0031] The technical solutions of the present utility model 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 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.

[0032] Referring to Figures 1 to 3, one embodiment of this utility model provides a buffer-type spring pad, including a housing 1. The housing 1 plays an important buffering role. Four sliding pillars 8 are fixedly connected inside the housing 1, and the four sliding pillars 8 are fixedly connected to the top inside the housing 1. Four limiting pillars 9 are fixedly connected inside the housing 1, and the four limiting pillars 9 are fixedly connected to the bottom inside the housing 1. Springs 10 are fitted onto the outer walls of each of the four limiting pillars 9. When subjected to external force, the springs 10 can deform and generate elastic potential energy. Two heat insulation layers 6 are provided inside the housing 1, so that the heat generated when the housing 1 is compressed can be absorbed, thereby significantly reducing the impact of the pressure. To improve the service life of the housing 1, a rubber layer 7 is fixedly connected to one side of the two heat insulation layers 6, making the elastic recovery of the housing 1 more powerful. A telescopic component is fixedly connected to the outer wall of the housing 1. The telescopic component includes multiple protrusions 4. The outer walls of the multiple protrusions 4 are fixedly connected to the outer wall of the housing 1. The multiple protrusions 4 are arranged in an irregular order on the outer wall of the housing 1. Multiple grooves 3 are opened on the outer wall of the housing 1. Multiple through holes 5 are opened on both sides of the housing 1, so that the gas generated inside the housing 1 when it is squeezed can be discharged, thereby greatly improving the service life of the housing 1.

[0033] Referring to Figures 2 to 4, the cross-sectional shape of the limiting post 9 is U-shaped. The outer walls of the four sliding posts 8 are slidably connected to the inner walls of the four limiting posts 9, making the outer walls of the sliding posts 8 slide more smoothly on the inner walls of the limiting posts 9. Both sides of the spring 10 are fixedly connected to the inside of the housing 1, so that the spring 10 can be squeezed by external force to generate elastic force. Expansion joints 2 are provided on both sides of the housing 1. Due to the existence of expansion joints 2, the elastic threshold that the housing 1 can withstand is greatly increased. The outer wall of the spring 10 is in contact with one side of the heat insulation layer 6 and the outer wall of the spring 10 is in contact with one side of the rubber layer 7, making the whole device more stable. The heat insulation layer 6 is made of heat insulation material, so that the heat insulation layer 6 can effectively isolate heat. The rubber layer 7 is made of rubber material, so that the rubber layer 7 can share some of the external force on the housing 1. The cross-sectional shape of the housing 1 is rectangular, and the shape of the through hole 5 is circular, making the whole device more aesthetically pleasing. The cross-section of the protrusion 4 is circular, and the cross-sectional shape of the expansion joint 2 is rectangular, which greatly increases the degree to which the housing 1 can withstand compression.

[0034] Working principle: When the housing 1 is subjected to an external force, due to its material properties, the housing 1 will be squeezed inward, causing the outer wall of the sliding column 8 to slide relative to the inner wall of the limiting column 9. At the same time, the spring 10 will be squeezed, causing the spring 10 to deform and generate elastic potential energy. When the external force on the housing 1 disappears, the elastic potential energy of the spring 10 will burst instantly, causing the elastic force of the spring 10 to restore the housing 1 to its original shape, and at the same time restore the positional relationship between the sliding column 8 and the limiting column 9 to its original state, ready for the next operation. When the housing 1 is squeezed by an external force, the expansion joint 2, the groove 3 and the protrusion 4 play an important stretching role, which greatly increases the elastic threshold of the housing 1. Due to the presence of the through hole 5, the gas generated inside the housing 1 after being squeezed can be ejected outward. Due to the presence of the heat insulation layer 6, the heat generated by the housing 1 after being squeezed is isolated, further protecting the internal structure of the housing 1 and greatly extending the service life of the housing 1.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
