Technical Field

[0001] This utility model relates to the field of buffer technology, specifically a buffer with self-lubricating function. Background Technology

[0002] A shock absorber is a mechanical device used to absorb impact energy, reduce vibration, and lower noise. It mainly uses elastic elements (such as springs and rubber), fluid damping (such as hydraulic oil), or electromagnetic force to convert the kinetic energy of moving parts into heat energy or elastic potential energy, thereby mitigating the damage of impact loads to equipment.

[0003] Utility model patent CN221628707U discloses a spring damper, relating to the field of dampers. It includes a base with a housing on top. A spring body is housed within the housing. Fixing components are symmetrically arranged on both sides of the housing. Each fixing component includes a first fixing strip, two second fixing strips, and fixing bolts. The bottom of the first fixing strip is fixedly connected to the base, and the two second fixing strips are respectively located on either side of the first fixing strip. When the spring body needs to be replaced, the fixing bolts are unscrewed, the housing is pulled upwards, and the base plate is removed from the limiting block. The base plate of the new spring body is then inserted into the limiting block. The second fixing strips on both sides of the housing are aligned with the first fixing strip, so that the first fixing strip is inserted between the two second fixing strips. After the housing is fully inserted, the fixing bolts are tightened back in. This allows for quick replacement of the spring body, facilitating replacement when the spring body ages, and making it more convenient to use.

Therefore, improvements are needed. Utility Model Content

The pressure block 6 is slidably connected to the connecting sleeve 3 and the rotating rod 4. A pressure rod 7 is fixedly connected to the top of the pressure block 6. The pressure rod 7 is slidably connected to the connecting sleeve 3. A sealing ring 10 is slidably sleeved on the outside of the pressure rod 7. The sealing ring 10 is fixedly connected to the connecting sleeve 3. By designing the sealing ring 10, the connection between the pressure rod 7 and the connecting sleeve 3 can be sealed. A pressure plate 11 is fixedly connected to the top of the pressure rod 7. A lubrication adjustment mechanism 8 is provided on the connecting sleeve 3. A limit mechanism 9 is provided on the lubrication adjustment mechanism 8.

[0023] Please see Figure 1 , Figure 2 , Figure 3 The lubrication adjustment mechanism 8 includes a sponge sleeve 81. The lower end of the pressure block 6 is fixedly connected to the sponge sleeve 81, which is slidably connected to the connecting sleeve 3. The sponge sleeve 81 is in contact with the buffer spring 5. The right end of the connecting sleeve 3 is fixedly connected to a filling port 82, which is in contact with the sponge sleeve 81. The top of the filling port 82 is connected to a cap 83 by a thread. A support block 84 is slidably sleeved inside the connecting sleeve 3, which is in contact with the buffer spring 5. The support block 84 is connected to the rotating rod 4 by a thread. Guide blocks 85 are fixedly connected to both ends of the support block 84. The connecting sleeve 3 is slidably connected. The guide block 85 is designed to guide the movement of the support block 84. A bevel gear 86 is fixedly sleeved on the outside of the rotating rod 4. A bevel gear 87 meshes on the outside of the bevel gear 86. A rotating block 88 is fixedly connected to the right end of the bevel gear 87. The rotating block 88 is rotatably connected to the connecting sleeve 3. An internal hexagonal groove is opened inside the rotating block 88. A plug 89 is in contact with the right end of the rotating block 88. The plug 89 is engaged with the connecting sleeve 3. The buffer spring 5 can be automatically lubricated by the lubrication adjustment mechanism 8, and the buffer performance of the buffer spring 5 can also be adjusted.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The limiting mechanism 9 includes a groove 91. A groove 91 is formed inside the rotating block 88. A retaining ball 92 is movably fitted inside the groove 91. There are multiple grooves 91, evenly distributed inside the rotating block 88. By designing multiple grooves 91, the retaining ball 92 can roll into different positions within the grooves 91. A fixing seat 93 is movably fitted outside the retaining ball 92. The fixing seat 93 is rotatably connected to the rotating block 88 and fixedly connected to the connecting sleeve 3. There is a connecting block 94, which is slidably connected to the fixed seat 93. A guide rod 95 is slidably sleeved inside the connecting block 94 and fixedly connected to the fixed seat 93. A clamping spring 96 is provided on the outside of the guide rod 95. One end of the clamping spring 96 is fixedly connected to the connecting block 94 and the other end of the clamping spring 96 is fixedly connected to the fixed seat 93. By designing the clamping spring 96, the force of the clamping spring 96 can be applied to the connecting block 94. By designing the limiting mechanism 9, it is convenient to limit the rotation block 88.

[0025] The specific implementation process of this utility model is as follows: In use, when the pressure plate 11 is subjected to force and moves downward, the pressure plate 11 will drive the pressure rod 7 and the pressure block 6 to move downward. The pressure block 6 slides along the rotating rod 4 and squeezes the buffer spring 5, thus playing a buffering role. When the pressure block 6 moves downward, it will drive the sponge sleeve 81 to move downward. The sponge sleeve 81 can move along the surface of the buffer spring 5, and the lubricating oil inside the sponge sleeve 81 can lubricate the buffer spring 5, reducing the wear of the buffer spring 5 and improving its service life. When the cover 83 is rotated, the cover 83 can be separated from the filling port 82, and then lubricating oil can be easily added to the inside of the sponge sleeve 81 for use.

[0026] When the buffering performance needs to be adjusted, first pull out the plug 89, then insert the hex wrench into the rotating block 88 and rotate the rotating block 88. The rotating block 88 drives the second bevel gear 87 to rotate, and the second bevel gear 87 drives the first bevel gear 86 and the rotating rod 4 to rotate, so that the support block 84 will make a threaded movement. The support block 84 will drive the guide block 85 to move upward. The movement of the support block 84 can adjust the pre-compression of the buffer spring 5, and the buffering performance of the buffer spring 5 can be flexibly adjusted.

[0027] When the rotating block 88 rotates, the arc surface of the groove 91 inside the rotating block 88 will squeeze and push the retaining ball 92, causing the retaining ball 92 to roll downwards. The retaining ball 92 will drive the connecting block 94 to move downwards. The connecting block 94 can slide along the guide rod 95 to squeeze and press the clamping spring 96, which can separate the retaining ball 92 from the groove 91. After the rotating block 88 has finished rotating, the elastic action of the clamping spring 96 will give the connecting block 94 an upward counter-force, which can push the retaining ball 92 into the groove 91 in another position. The retaining ball 92 can limit the rotating block 88, and thus limit the bevel gear 2 87, bevel gear 1 86 and rotating rod 4. This can prevent the random rotation of the rotating block 88 after the position of the support block 84 is adjusted, which will affect the stability of the fixed position of the support block 84, and improve the stability of the buffer performance adjustment of the buffer spring 5.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
