In addition, when adjusting and controlling the elastic properties of the existing clamping cylinders, complex mechanical structures and additional adjustment devices are usually required, which increases the manufacturing cost and maintenance difficulty. Therefore, the prior art urgently needs a clamping cylinder mechanism with a buffer stretching structure to achieve a smooth buffer stretching effect, while simplifying the adjustment process of its elastic properties and improving the reliability and service life of the equipment.

[0028] Example 1

[0029] like Figure 1-4As shown, the utility model provides a technical solution: a clamping cylinder mechanism with a buffer stretching structure, comprising: a buffer mechanism 1, a disassembly mechanism 2 is arranged inside the buffer mechanism 1, the buffer mechanism 1 comprises a hollow tube 11, a bottom end of the hollow tube 11 is provided with a chassis 12, an inner tube 13 is arranged on the top of the chassis 12, an inner wall of the inner tube 13 is provided with a spring sheet 17, an adjusting rod 15 is arranged on the inner wall of the middle end of the spring sheet 17, a middle plate 14 is arranged at one end of the adjusting rod 15, a screw rod is arranged inside the middle plate 14 19, a chassis 12 is arranged on the outside of the screw rod 19, a guide rod 16 is arranged on the top of the chassis 12, an adjusting rod 15 is arranged on the outside of the guide rod 16, an inner tube 13 is arranged on one end of the side of the adjusting rod 15, an outer ring 110 is arranged on the top of the inner tube 13, a roller 111 is arranged on the inner side of one end of the outer ring 110, a hollow tube 11 is arranged on the outer side of the roller 111, a folding rod 18 is arranged on one end of the spring piece 17, an outer ring 110 is arranged on one end of the folding rod 18, and a cylinder body 112 is arranged on the inner side of the outer ring 110.

[0030] In this embodiment, when the device is in use, if the clamping cylinder needs to be buffered, the clamping cylinder will apply external force to the outer ring 110, so that it moves downward in the hollow tube 11, and in the process of moving downward, the outer ring 110 will squeeze the spring sheet 17, so that the spring sheet 17 is squeezed to make it retract, so that the clamping cylinder performs buffering. When the external force disappears, the spring sheet 17 will be released to restore each component to its initial position. Therefore, the clamping cylinder can achieve a stable buffering and stretching effect, reduce impact and vibration, and improve the durability of the equipment;

[0031] Secondly, by rotating the screw rod 19, the center plate 14 moves downward. As the center plate 14 moves downward, the adjustment rod 15 on the spring 17 will be adjusted simultaneously, so that the adjustment rod 15 and the spring 17 are integrated. Therefore, the spring 17 will be compressed after moving downward. Through this compression process, the elastic properties of the spring 17 can be effectively adjusted, and the degree of compression of the spring 17 can be accurately adjusted to ensure that the system can achieve optimal performance under various conditions.

[0032] Example 2

[0033] like Figure 1-4 As shown, the disassembly mechanism 2 includes a limit block 21, one side of the limit block 21 is vertically in contact with one end of the fixed block 22, the interior of the fixed block 22 is threadedly connected to one end of the fixing member 23, one end of the fixing member 23 is threadedly connected to the inner wall of the outer ring 110, the interior of the outer ring 110 is slidably connected to the outer side of the limit block 21, and one end of the limit block 21 is clamped with the inner wall of the cylinder body 112.

[0034] In this embodiment, by removing the fixing member 23 from the fixing block 22, the fixing state of the fixing block 22 is released, and the fixing block 22 can be taken out from the outer ring 110. With the removal of the fixing block 22, the limit block 21 is no longer blocked by the fixing block 22 and is released, and the limit block 21 can be taken out from the cylinder body 112. Through this operation, the cylinder body 112 can also be smoothly removed from the outer ring 110, so as to facilitate the inspection, maintenance or replacement of these components. The entire disassembly process is simpler and faster, which improves the efficiency of repairing and replacing components, and also reduces the difficulty and labor intensity of operation.

[0035] Working principle:

[0036] like Figure 1-4 As shown, when the clamping cylinder exerts pressure on the outer ring 110, it will move downward in the hollow tube 11, and in the process of moving downward, the outer ring 110 will squeeze the spring piece 17. Therefore, by squeezing the spring piece 17 to cause it to retract, the clamping cylinder performs buffering. When the external force disappears, the spring piece 17 will be released and the various components will be restored to their initial positions. The screw rod 19 will be rotated to move the center plate 14 downward. As the center plate 14 moves downward, the adjusting rod 15 on the spring piece 17 will be adjusted in a simultaneous manner, and the adjusting rod 15 and the spring piece 17 are integrated. Therefore, the spring piece 17 will be compressed after moving downward. Through this compression process, the elastic performance of the spring piece 17 can be effectively adjusted.

[0037] The fixing member 23 is removed from the fixing block 22 to release the fixing state of the fixing block 22. At this time, the fixing block 22 can be taken out of the outer ring 110. With the removal of the fixing block 22, the limit block 21 is no longer blocked by the fixing block 22 and is released, and the limit block 21 can be taken out of the cylinder body 112. Through this operation, the cylinder body 112 can also be smoothly removed from the outer ring 110, so as to facilitate the inspection, maintenance or replacement of these components.

Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.

[0039] The utility model is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims.
