The three-pronged plate is located on the top of the rubber column and sleeved on the outside of the bolt. The fixing nut is threadedly connected to the bolt and abuts against the three-pronged plate. The adsorption mechanism consists of three sets, each located at one of the three ends of the three-pronged plate. Its advantages are: by setting three sets of adsorption mechanisms in conjunction with the three-pronged plate, the device can adhere to the ground using three sets of suction cups during use, preventing the device from shifting, avoiding severe friction between the bottom of the rubber column and the ground, and extending the service life of the rubber column. The device is an assembled assembly, facilitating subsequent repair and maintenance. However, its structure is complex and its production cost is high. Utility Model Content

[0017] 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.

[0018] Example 1:

[0019] This utility model provides a wear-resistant rubber shock-absorbing pad, including a wear-resistant base plate 1, rubber pillars 2, and connectors 3. The wear-resistant base plate 1 is provided with guide pillars 4, and the rubber pillars 2 are provided with through holes 5. The connectors 3 include a pressure plate 6 and a stud 7. The pressure plate 6 is provided with a movable hole 8. The guide pillars 4 pass through the through holes 5 and the movable holes 8 in sequence. The guide pillars 4 are provided with threaded sections 9, and the threaded sections 9 are fixedly connected to nuts 10. The bottom of the wear-resistant base plate 1 is provided with a fixing groove 11, and an anti-slip plate 12 is fixedly installed in the fixing groove 11. The wear-resistant base plate 1 is provided with three equidistant support arms 13. The support arms 13 are provided with connecting seats 14. The connecting seats 14 are provided with screw holes 15, and the screw holes 15 are engaged with hand-tightening bolts 16. One end of the hand-tightening bolt 16 is provided with a convex shaft 17, and an anti-slip rubber block 18 is movably installed on the convex shaft 17. The anti-slip rubber block 18 is made of polyurethane. The wear-resistant base plate 1 is made of stainless steel.

[0020] Through the above technical solution, the wear-resistant base plate 1 of this utility model is provided with guide posts 4. The guide posts 4 pass through the through holes 5 of the rubber column 2 and the movable holes 8 of the pressure plate 6 in sequence, and are fastened together by nuts 10. In use, the studs 7 of the connecting parts 3 are fixedly connected to the equipment. The pressure generated by the equipment support is transmitted to the pressure plate 6 through the studs 7, and then the pressure plate 6 acts on the rubber column 2, thereby realizing the shock absorption function. The wear-resistant base plate 1 is located at the bottom of the rubber column 2, and its bottom surface is equipped with anti-slip plates 12, which helps to enhance the installation stability of the equipment. When the equipment vibrates violently and displacement occurs, the wear-resistant base plate 1 can effectively protect the rubber column 2, avoid its direct wear, and thus extend its service life.

[0021] Example 2:

[0022] In this embodiment, the wear-resistant base plate 1 is provided with guide posts 4, which extend upward from the wear-resistant base plate 1 to form a support structure. The rubber post 2 is provided with through holes 5, which penetrate the upper and lower surfaces of the rubber post 2, allowing the guide post 4 to pass through. The connecting component 3 includes a pressure plate 6 and a stud 7. The pressure plate 6 is provided with a movable hole 8, the size of which is slightly larger than the diameter of the guide post 4, allowing the pressure plate 6 to move slightly on the guide post 4. The guide post 4 passes sequentially through the through hole 5 of the rubber post 2 and the movable hole 8 of the pressure plate 6. The top of the guide post 4 is provided with a threaded section 9, on which a nut 10 is fixedly connected. By tightening the nut 10, the components are pressed and fixed. The bottom of the wear-resistant base plate 1 is provided with a fixing groove 11, which is a recessed structure. An anti-slip plate 12 is embedded in the fixing groove 11 and securely installed. The anti-slip plate 12 is made of a high-friction coefficient material to enhance the adhesion between the shock-absorbing pad and the contact surface.

[0023] During the assembly of the shock-absorbing pad, the rubber column 2 is first placed above the wear-resistant base plate 1, aligning the guide column 4 and passing it through the through hole 5 of the rubber column 2. Then, the movable hole 8 of the pressure-distributing plate 6 is fitted into the guide column 4, ensuring that the pressure-distributing plate 6 is positioned at the top of the rubber column 2. After the threaded section 9 of the guide column 4 protrudes from the pressure-distributing plate 6, it is tightened with a nut 10. The pressure applied by the nut 10 is transmitted to the rubber column 2 through the pressure-distributing plate 6, compressing and fixing the rubber column 2 to the wear-resistant base plate 1. The stud 7 of the connector 3 is used for connection to external equipment, and the vibration generated by the equipment is transmitted to the pressure-distributing plate 6 through the stud 7. The pressure-distributing plate 6 disperses the vibration energy onto the rubber column 2, which absorbs and buffers the vibration through its elastic deformation, achieving a shock-absorbing effect. The wear-resistant base plate 1 serves as the basic support, and its bottom anti-slip plate 12 increases friction to prevent the shock-absorbing pad from sliding during use, avoiding wear problems caused by displacement.

[0024] When equipment operation generates strong vibrations, the vibration damping pad operates based on energy dispersion and friction control. Equipment vibration is transmitted to the pressure-distributing plate 6 via the studs 7. The pressure-distributing plate 6 evenly distributes the force onto the surface of the rubber pillars 2. The rubber pillars 2, through their elastic properties, convert mechanical energy into heat energy, thereby reducing the vibration amplitude. The cooperation between the guide pillars 4 and the movable holes 8 allows the pressure-distributing plate 6 to have slight displacement during vibration, adapting to forces in different directions and preventing stress concentration. The wear-resistant base plate 1 not only supports the overall structure but also enhances stability through anti-slip plates 12. The anti-slip plates 12 are embedded in the fixing grooves 11 to ensure they do not fall off during long-term use, effectively reducing relative movement between the base plate and the ground. This design avoids direct contact between the rubber pillars 2 and hard surfaces, extending the service life of the vibration damping pad, while also simplifying the structure and reducing production costs.

[0025] In long-term use, the wear-resistant base plate 1 of the shock-absorbing pad bears the main wear, while the rubber pillars 2 are protected, reducing replacement frequency. The fixing groove 11 of the anti-slip plate 12 is designed to ensure its firm attachment, providing reliable anti-slip effect even on wet or smooth surfaces. The pressure-distributing plate 6 of the connector 3, through the clearance fit between the movable hole 8 and the guide post 4, allows for adaptive adjustment during vibration transmission, avoiding damage caused by rigid connections. The tightening force of the nut 10 can be adjusted according to actual needs to control the degree of compression of the rubber pillars 2, thereby optimizing shock absorption performance. The overall structure is compact, easy to install and maintain, and suitable for various industrial equipment, such as machine bases or transport vehicles, providing stable shock absorption and wear resistance.

[0026] Example 3:

[0027] In this embodiment, the wear-resistant base plate 1 is made of high-strength composite material. Its bottom has a fixing groove 11, within which an anti-slip plate 12 is securely installed. The anti-slip plate 12 is made of wear-resistant rubber material with a finely textured surface to enhance frictional resistance when in contact with the ground. A guide post 4 is vertically positioned above the wear-resistant base plate 1. The guide post 4 passes through the through hole 5 of the rubber post 2 and the movable hole 8 of the connector 3. A threaded section 9 is machined at the top of the guide post 4, and a nut 10 is used to secure it, achieving a stable connection of the overall structure. The connector 3 includes a pressure-distributing plate 6 and a stud 7. The pressure-distributing plate 6 is responsible for distributing the pressure transmitted by the equipment, while the stud 7 is used for fixed connection with the equipment support, ensuring that vibration energy is effectively transmitted to the damping structure.

[0028] Three support arms 13 are equidistantly distributed around the perimeter of the wear-resistant base plate 1, extending radially. Each support arm 13 has a connecting seat 14 at its end. The connecting seat 14 has a square structure with a screw hole 15 machined in the center. The screw hole 15 is threaded to fit a hand-tightening bolt 16. One end of the hand-tightening bolt 16 is designed as a convex shaft 17 with a smooth surface, forming a rotating connection with the movable hole 8 of the anti-slip rubber block. The anti-slip rubber block is made of highly elastic rubber material, and its bottom surface is designed with anti-slip patterns. When the hand-tightening bolt 16 is screwed into the screw hole 15, the anti-slip rubber block is gradually pushed out, forming a tight contact with the ground.

[0029] The working principle of this embodiment is as follows: When the equipment vibrates, the vibration energy is transmitted to the pressure-distributing plate 6 through the stud 7. The pressure-distributing plate 6 evenly distributes the pressure to the rubber pillars 2, which absorb and buffer the vibration using their elastic properties. The wear-resistant base plate 1 serves as a supporting foundation, providing initial anti-slip effect through the anti-slip plate 12. When the equipment tends to shift, the operator can rotate the hand-tightening bolt 16 to push the anti-slip rubber block downwards, increasing the contact pressure with the ground and thus significantly improving the overall structure's anti-slip capability. The movable connection design between the convex shaft 17 and the anti-slip rubber block ensures that the anti-slip rubber block remains stationary during the rotation of the hand-tightening bolt 16, avoiding the impact of frictional resistance on the bolt's screwing operation and ensuring the smoothness of the adjustment process.

[0030] In practical applications, this shock-absorbing pad is suitable for vibration damping installation on various industrial equipment. When the equipment requires long-term stable operation, the anti-slip rubber block can be reliably pressed against the ground by adjusting the hand-tightened bolts 16 on the three support arms 13, effectively preventing displacement of the shock-absorbing pad during use. This design maintains the shock-absorbing performance of the pad while enhancing installation stability through an adjustable anti-slip mechanism. The elastic properties of the anti-slip rubber block allow it to adapt to ground surfaces of varying flatness, ensuring good anti-slip performance under various working conditions.

[0031] The structural design of this embodiment fully considers ease of use and reliability. The anti-slip force can be adjusted through a simple rotation operation, requiring no additional tools. The equidistant arrangement of the three support arms 13 ensures uniform force distribution, avoiding the problem of stress concentration at single points. The entire adjustment mechanism coordinates with the main shock-absorbing structure, effectively improving the practical performance and lifespan of the shock-absorbing pad without excessively increasing structural complexity. The replaceable design of the anti-slip rubber blocks also facilitates maintenance after long-term use; when the anti-slip rubber blocks wear down, they can be replaced individually without affecting the overall structure.

[0032] Example 4:

[0033] In this embodiment, the wear-resistant base plate 1 is provided with guide posts 4, the rubber posts 2 are provided with through holes 5, and the connecting parts 3 include pressure plates 6 and studs 7. The pressure plates 6 are provided with movable holes 8. The guide posts 4 pass through the through holes 5 and movable holes 8 in sequence. The guide posts 4 are provided with threaded sections 9, and nut 10 is fixedly connected to the threaded sections 9. The bottom of the wear-resistant base plate 1 is provided with a fixing groove 11, and anti-slip plates 12 are fixedly installed in the fixing groove 11. The wear-resistant base plate 1 is provided with three support arms 13 at equal intervals. The support arms 13 are provided with connecting seats 14. The connecting seats 14 are provided with screw holes 15, and hand-tightening bolts 16 are engaged with the screw holes 15. One end of the hand-tightening bolts 16 is provided with a convex shaft 17, and an anti-slip rubber block is movably installed on the convex shaft 17. The anti-slip rubber block is made of polyurethane. By screwing the hand-tightening bolt 16 into the screw hole 15, the anti-slip rubber block is pushed out and pressed against the ground, which increases the friction between the wear-resistant base plate 1 and the ground. The movable connection between the convex shaft 17 and the anti-slip rubber block prevents the hand-tightening bolt 16 from being subjected to the friction of the anti-slip rubber block when rotating, thus improving the smoothness of screwing in.

[0034] During the installation of the shock-absorbing pad, the studs 7 of the connector 3 are fixedly connected to the equipment. The pressure generated by the equipment bracket is transmitted to the pressure-distributing plate 6 via the studs 7, and then the pressure-distributing plate 6 acts on the rubber column 2, thereby achieving the shock absorption function. The wear-resistant base plate 1 is located at the bottom of the rubber column 2, and its bottom surface is equipped with anti-slip pads 12, which helps to enhance the installation stability of the equipment. When the equipment vibrates violently and displacement occurs, the wear-resistant base plate 1 can effectively protect the rubber column 2, preventing it from being directly worn, thereby extending its service life. The anti-slip pads are made of polyurethane, which has excellent wear resistance and pressure resistance, and can maintain a stable anti-slip effect during long-term use. The high elasticity and toughness of polyurethane material enable it to effectively disperse stress when subjected to pressure, reducing local wear. At the same time, its low coefficient of friction helps to facilitate the smooth operation of the hand-tightening bolts 16, avoiding difficulty in tightening due to excessive friction.

[0035] In practical applications, the shock-absorbing pad achieves precise positioning and stable connection through the guide post 4 of the wear-resistant base plate 1 and the through hole 5 of the rubber post 2. The movable hole 8 of the pressure plate 6 allows for fine-tuning of its position under pressure to adapt to the vibration characteristics of different equipment. The tightening effect of the nut 10 ensures the overall structural integrity and prevents loosening under long-term vibration. The installation of the anti-slip plate 12 further enhances the adhesion between the shock-absorbing pad and the ground, reducing the risk of slippage. The anti-slip rubber block can be adjusted by tightening the hand-tightening bolt 16 according to the ground conditions, ensuring reliable anti-slip performance in different working environments. The polyurethane anti-slip rubber block is not only wear-resistant and durable, but also maintains stable performance in wet or oily environments, avoiding anti-slip failure caused by environmental factors.

[0036] The vibration damping pad in this embodiment has a simple structure and is easy to assemble, requiring no complex tools for installation and adjustment. The use of polyurethane anti-slip rubber blocks significantly improves the wear resistance and service life of the damping pad while reducing maintenance costs. By optimizing the connection method and material selection, this vibration damping pad effectively solves the problems of easy wear and displacement of traditional damping pads while ensuring damping performance, making it suitable for various fields such as industry, construction, and transportation. The overall design emphasizes practicality and economy, avoiding the disadvantages of complex structures and high production costs in existing technologies, and providing an efficient and reliable vibration damping solution.

[0037] Example 5:

[0038] In this embodiment, the wear-resistant base plate 1 is made of stainless steel. This base plate is located at the bottom of the shock-absorbing pad and, together with the rubber pillar 2 and the connecting member 3, forms a shock-absorbing structure. A guide post 4, cylindrical in shape, extends upwards from the base plate on the upper surface of the wear-resistant base plate 1. A through hole 5 is provided at the center of the rubber pillar 2, through which the guide post 4 can pass. The connecting member 3 includes a pressure plate 6 and a stud 7. The pressure plate 6 has a movable hole 8. After the guide post 4 passes through the through hole 5 of the rubber pillar 2 and the movable hole 8 of the pressure plate 6, its threaded section 9 at the top is fixedly connected by a nut 10. A fixing groove 11 is provided at the bottom of the wear-resistant base plate 1, and an anti-slip plate 12 is embedded in the fixing groove 11 to ensure the stability of the shock-absorbing pad when in contact with the ground.

[0039] During the operation of the shock-absorbing pad, the equipment is fixed to the pad via studs 7 of the connector 3. The vibrations and pressures generated by the equipment are transmitted to the pressure-distributing plate 6 through the studs 7. The pressure-distributing plate 6 evenly distributes the pressure onto the rubber columns 2, utilizing the elastic properties of the rubber material to absorb and buffer vibration energy, thereby achieving a shock-absorbing effect. The wear-resistant base plate 1 serves as the supporting foundation; its stainless steel material provides high strength and wear resistance, enabling it to withstand the impacts and friction during equipment operation. When the equipment experiences slight displacement due to vibration, the anti-slip pads 12 at the bottom of the wear-resistant base plate 1 increase friction to prevent the shock-absorbing pad from sliding, avoiding direct contact between the rubber columns 2 and the ground, thus reducing wear.

[0040] The stainless steel material chosen for the wear-resistant base plate 1 is based on its excellent mechanical properties and durability. Stainless steel has high hardness and corrosion resistance, enabling it to be used for extended periods in humid or corrosive environments without easily being damaged. During the assembly of the shock-absorbing pad, the guide post 4 passes through the rubber post 2 and the pressure plate 6, and is then secured with nuts 10 to ensure a tight connection between all components and prevent loosening. This structural design not only simplifies the installation process but also improves overall reliability. The embedded design of the anti-slip plate 12 further enhances the stability of the shock-absorbing pad, preventing accidental movement caused by vibration during equipment operation.

[0041] In practical applications, vibration damping pads are suitable for industrial machinery, construction equipment, or transportation vehicles, where the equipment requires stable vibration damping support to reduce noise and vibration impacts. The stainless steel material of the wear-resistant base plate 1 effectively resists wear and chemical corrosion from the external environment, extending the service life of the vibration damping pad. The elastic deformation capacity of the rubber column 2 ensures the continuity of the vibration damping effect, while the pressure distribution plate 6 design of the connector 3 optimizes pressure distribution and avoids local overload. The overall structure, through the protective function of the wear-resistant base plate 1, reduces maintenance requirements and improves economy and practicality.

[0042] This embodiment of the vibration damping pad achieves high wear resistance and structural strength through the stainless steel material of the wear-resistant base plate 1. Combined with the damping performance of the rubber column 2 and the pressure transmission mechanism of the connector 3, it provides a reliable vibration damping solution. The addition of the anti-slip plate 12 further enhances installation stability, ensuring that the vibration damping pad can work effectively under various operating conditions. This design not only solves the problem of easy wear of traditional vibration damping pads, but also reduces production costs by simplifying the structure, making it suitable for a wide range of industrial applications.
