[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] See also Figure 1-Figure 4 , the utility model provides the following technical solutions:

[0027] A hydraulic cylinder base, comprising:

[0028] Oil cylinder base 1;

[0029] Buffer mechanism, the buffer mechanism is provided with two groups, each group of buffer mechanism includes a sliding groove 2, a spring groove 3, a telescopic rod 4, an insertion groove 5, a support plate 6, a spring plate 7, a buffer spring 8, a clamping plate 9 and a rotating rod 10, the sliding groove 2 is opened on the circumferential inner wall of the cylinder base 1, the spring groove 3 is opened on the lower inner wall of the sliding groove 2, the insertion groove 5 is opened on the lower inner wall of the spring groove 3, the support plate 6 is fixedly connected to the circumferential inner wall of the insertion groove 5, the telescopic rod 4 is slidably connected to the insertion groove 5 and the spring groove 3, the spring plate 7 is fixedly connected to the circumferential surface of the telescopic rod 4 and slides in the spring groove 3, the buffer spring 8 is fixedly connected to the lower end of the spring plate 7 and the lower inner wall of the spring groove 3, the clamping plate 9 is slidably connected to the cylinder base 1 and the sliding groove 2, and the rotating rod 10 is rotatably connected to the upper end of the spring plate 7 and one side end of the clamping plate 9 through a rotating shaft.

[0030] In a specific embodiment of the utility model, a hydraulic cylinder is installed and fixed in the cylinder base 1, two clamping plates 9 clamp the hydraulic cylinder in the cylinder base 1 to fix it, and the support plate 6 abuts against the lower end of the telescopic rod 4 so that the telescopic rod 4 cannot slide in the spring groove 3, thereby fixing the clamping plate 9, so that the hydraulic cylinder will not shake in the cylinder base 1. When the cylinder base 1 is subjected to a large impact, the hydraulic cylinder squeezes the clamping plate 9, and the squeezing force on the clamping plate 9 is transmitted through the rotating rod 10 and the telescopic rod 4 to become the thrust of the telescopic rod 4 on the support plate 6. When the impact on the cylinder base 1 is too large, the clamping plate 9 is squeezed to slide into the sliding groove 2, and the telescopic rod 4 breaks through the support plate 6 and slides into the insertion groove 5, and the spring plate 7 is brought by the telescopic rod 4 The telescopic rod 4 is pushed upward by the resilience of the buffer spring 8 to continue clamping the hydraulic cylinder, so that when the impact force on the cylinder base 1 is small, the support plate 6 supports the telescopic rod 4 so that the clamping plate 9 cannot move and the hydraulic cylinder is fixed to prevent it from shaking. When the impact is too great and causes damage to the hydraulic cylinder, the telescopic rod 4 presses the support plate 6 so that the clamping plate 9 can be retracted into the sliding groove 2 and buffered by the buffer spring 8, so as to reduce the impact force on the hydraulic cylinder and protect the hydraulic cylinder.

[0031] For details, please refer to Figure 1-Figure 4 Two limiting slide grooves 11 are provided on the circumferential inner wall of the oil cylinder base 1 , and two limiting slide bars 12 are fixedly connected to one side end of the two clamping plates 9 , and the two limiting slide bars 12 slide in the two limiting slide grooves 11 respectively.

[0032] In this embodiment: the two limit slide bars 12 are respectively fixed to the two clamping plates 9 of the fixed hydraulic cylinder to limit the sliding direction of the clamping plates 9, so that the clamping plates 9 can only move laterally into the sliding groove 2 to squeeze the buffer spring 8 for contraction without deviation.

[0033] For details, please refer to Figure 1-Figure 4 , the supporting plate 6 is made of polyethylene material.

[0034] In this embodiment: the support plate 6 is a plastic made of polyethylene material to support the telescopic rod 4 so that the clamping plate 9 cannot move. A thin-edged ring is provided around the support plate 6 so that it cannot support the telescopic rod 4 when the device is subjected to a large impact, so that the telescopic rod 4 can break the support plate 6 for telescopic shock absorption.

[0035] For details, please refer to Figure 1-Figure 4 The lower end of the oil cylinder base 1 is fixedly connected to a grounding seat 13 , and the lower end of the grounding seat 13 is provided with a plurality of grounding holes 14 .

[0036] In this embodiment: a grounding seat 13 is arranged at the lower end of the cylinder base 1 and contacts the ground to support the cylinder base 1. A plurality of grounding holes 14 are opened at the lower end of the grounding seat 13. The cylinder base 1 is fixed to the ground through the grounding holes 14 and the grounding nails, thereby improving the stability of the hydraulic cylinder.

[0037] For details, please refer to Figure 1-Figure 4 One side end of the two clamping plates 9 is fixedly connected with a clamping pad 15.

[0038] In this embodiment, the clamping pads 15 are arranged at the arc-shaped ends of the two clamping plates 9, and the two clamping pads 15 are in contact with the hydraulic cylinder, so that when the device is hit, the surface of the hydraulic cylinder will not be scratched by the clamping plates 9 when it shakes.

[0039] For details, please refer to Figure 1-Figure 4 A plurality of contact pads 16 are fixedly connected to the circumferential inner wall of the cylinder base 1 .

[0040] In this embodiment: the contact pad 16 is arranged on the inner wall of the cylinder base 1, and the side end of the contact pad 16 and the arc of the two contact pads 16 form a ring to clamp the hydraulic cylinder and share the clamping force on the cylinder, so that the hydraulic cylinder will not shake in the cylinder base 1.

[0041] The working principle and use process of the utility model are as follows: the hydraulic cylinder is installed and fixed in the cylinder base 1, two clamping plates 9 clamp the hydraulic cylinder in the cylinder base 1 to fix it, the support plate 6 abuts against the lower end of the telescopic rod 4 so that the telescopic rod 4 cannot slide in the spring groove 3 and then fixes the clamping plate 9, so that the hydraulic cylinder will not shake in the cylinder base 1. When the cylinder base 1 is subjected to a large impact, the hydraulic cylinder squeezes the clamping plate 9, and the squeezing force on the clamping plate 9 is transmitted through the rotating rod 10 and the telescopic rod 4 to become the thrust of the telescopic rod 4 on the support plate 6. When the impact on the cylinder base 1 is too large, the clamping plate 9 is squeezed to slide into the sliding groove 2, the telescopic rod 4 squeezes the support plate 6 and slides into the insertion groove 5, and the spring plate 7 is squeezed by the telescopic rod 4. The support plate 6 of the telescopic rod 4 is pressed against the support plate 6 to prevent the clamping plate 9 from moving and to fix the hydraulic cylinder. When the impact is too great and causes damage to the hydraulic cylinder, the support plate 6 presses the support plate 6 to allow the clamping plate 9 to be retracted into the sliding groove 2 and to be buffered by the buffer spring 8, thereby reducing the impact force on the hydraulic cylinder.

[0042] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
