[0002] Oil cylinder generally refers to hydraulic cylinder, which is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion or swinging motion. It has a simple structure and reliable operation. In the prior art, the oil cylinder is fixed by an oil cylinder fixing base, which has a good fixing effect. However, the traditional oil cylinder fixing base lacks a shock-absorbing structure, and long-term vibration causes looseness between components, which is prone to safety hazards.

[0003] Therefore, it is necessary to provide a new oil cylinder base to solve the above-mentioned technical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a cylinder base.

[0005] The oil cylinder base provided by the utility model comprises:

[0006] Mounting substrate, and

[0007] A mounting plate mounted on the mounting base plate, and two symmetrically distributed shaft rod brackets are fixedly mounted on the mounting plate, each of the shaft rod brackets is provided with a drainage hole for supplying oil to the shaft cavity of the shaft rod bracket;

[0008] An elastic corrugated oil storage bag is installed between the mounting base plate and the mounting plate, a one-way air inlet valve is installed on the side bag wall of the elastic corrugated oil storage bag near the top, and a one-way oil drain valve is installed on the bag wall of the elastic corrugated oil storage bag near the bottom, and an oil guide pipe for guiding oil to the drain hole is installed on the one-way oil drain valve.

[0009] Preferably, the shaft support is provided with a plurality of drainage holes distributed in an annular pattern, and the drainage holes are interconnected through an annular flow channel provided in the shaft support. The shaft support is also provided with an oil inlet chamber connected to the annular flow channel, and the oil inlet chamber is interconnected with the oil discharge end of the oil guide pipe.

[0010] Preferably, the upper and lower bag walls of the elastic pleated oil storage bag are respectively fixedly connected to the lower plate wall of the mounting plate and the upper plate wall of the mounting base plate.

[0011] Preferably, a plurality of springs A are embedded in the elastic pleated oil storage bag, and two ends of the spring A are respectively fixedly connected to the upper and lower inner bag walls of the elastic pleated oil storage bag.

[0012] Preferably, a plurality of connecting parts are provided between the mounting base plate and the mounting plate, and the connecting parts include a sliding rod, the sliding rod is fixedly mounted on the mounting base plate, and the other end of the sliding rod passes through a through hole opened in the mounting plate and is fixedly mounted with a rod cap, and a spring B is connected in series on the sliding rod.

[0013] Preferably, one end of the spring B is fixedly connected to the upper surface of the mounting substrate, and the other end of the spring B is fixedly connected to the lower surface of the mounting plate.

[0014] Preferably, a rotatably connected shaft is inserted between the two shaft brackets.

[0015] Compared with the related art, the oil cylinder base provided by the utility model has the following beneficial effects:

[0016] When the oil cylinder is driven and vibrates, the mounting plate is driven to slide down along the sliding rod, and the spring B on the sliding rod is compressed and the elastic pleated oil storage bag is also compressed. At this time, under the damping effect of the lubricating oil inside the elastic pleated oil storage bag, most of the energy of the oil cylinder vibration can be offset.

Not only can the shaft rod be lubricated but also the heat can be dissipated, which greatly improves the stability of the connection between the oil cylinder and the shaft rod.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0024] See also Figures 1 to 4 An embodiment of the utility model provides an oil cylinder base, which includes: a mounting base plate 1, a mounting plate 2, an axle rod bracket 3 and an elastic pleated oil storage bag 4.

[0025] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 , a mounting plate 2 is mounted on the mounting base plate 1, specifically, an elastic pleated oil storage bag 4 is mounted between the mounting base plate 1 and the mounting plate 2, and a plurality of springs A5 are embedded in the elastic pleated oil storage bag 4, and the two ends of the spring A5 are respectively fixedly connected to the upper and lower inner bag walls of the elastic pleated oil storage bag 4;

[0026] A plurality of connecting members 6 are provided between the mounting substrate 1 and the mounting plate 2, and the connecting member 6 includes a sliding rod 61, the sliding rod 61 is fixedly mounted on the mounting substrate 1, and the other end of the sliding rod 61 passes through a through hole provided in the mounting plate 2 and is fixedly mounted with a rod cap 62, a spring B63 is serially connected to the sliding rod 61, one end of the spring B63 is fixedly connected to the upper surface of the mounting substrate 1, and the other end of the spring B63 is fixedly connected to the lower surface of the mounting plate 2;

[0027] Two symmetrically distributed shaft rod brackets 3 are fixedly mounted on the mounting plate 2 , and a rotatably connected shaft rod 7 is inserted between the two shaft rod brackets 3 .

[0028] It should be noted that when installing the oil cylinder, the oil cylinder mounting socket is inserted between the two shaft rod brackets 3, and then the shaft rod 7 is inserted through the two shaft rod brackets 3 to rotate the oil cylinder.

[0029] When the oil cylinder is driven and vibrates, driving the erection plate 2 to slide down along the sliding rod 61, the spring B63 on the sliding rod 61 is compressed and at the same time the elastic pleated oil storage bag 4 is also compressed. At this time, under the damping effect of the lubricating oil inside the elastic pleated oil storage bag 4, most of the energy of the oil cylinder vibration can be offset. At the same time, the extrusion deformation of the spring B63 and the pleating contraction of the elastic pleated oil storage bag 4 greatly reduce the amplitude of the oil cylinder, and also enhance the stability of the oil cylinder;

[0030] Therein, a plurality of springs A5 are embedded in the elastic pleated oil storage bag 4, and two ends of the spring A5 are fixedly connected to the upper and lower inner bag walls of the elastic pleated oil storage bag 4 respectively.

[0031] In the embodiments of the present invention, please refer to Figure 2 , Figure 3 and Figure 4 Each of the shaft supports 3 is provided with a drainage hole 3b for supplying oil to the shaft cavity of the shaft support 3. The shaft support 3 is provided with a plurality of drainage holes 3b distributed in an annular shape, and the drainage holes 3b are interconnected through an annular flow channel 3a provided in the shaft support 3. The shaft support 3 is also provided with an oil inlet chamber 3c connected to the annular flow channel 3a. A one-way air inlet valve 41 is installed on the side bag wall of the elastic pleated oil storage bag 4 near the top, and a one-way oil drain valve 42 is installed on the bag wall of the elastic pleated oil storage bag 4 near the bottom. An oil guide pipe 43 for guiding oil to the drainage hole 3b is installed on the one-way oil drain valve 42, and the oil drain end of the oil guide pipe 43 is interconnected with the oil inlet chamber 3c.

[0032] It should be noted that: when the elastic pleated oil storage bag 4 is compressed, the lubricating oil inside it has a damping effect on the elastic pleated oil storage bag 4 on the one hand, and on the other hand, part of the oil enters the annular flow channel 3a through the oil guide pipe 43, and is diverted from the annular flow channel 3a to the drainage hole 3b, thereby lubricating the shaft rod 7 mounted on the two shaft rod brackets 3, which can not only lubricate the shaft rod 7 but also dissipate heat from it, greatly improving the stability of the connection between the cylinder and the shaft rod 7.

[0033] The working principle of the oil cylinder base provided by the utility model is as follows:

[0034] When installing the oil cylinder, insert the oil cylinder installation socket between the two shaft rod brackets 3, and then insert the shaft rod 7 through the two shaft rod brackets 3 to rotatably install the oil cylinder; when the oil cylinder is driven and vibrates, driving the mounting plate 2 to slide down along the sliding rod 61, the spring B63 on the sliding rod 61 is compressed and the elastic pleated oil storage bag 4 is also compressed. At this time, under the damping effect of the lubricating oil inside the elastic pleated oil storage bag 4, most of the energy of the oil cylinder vibration can be offset, and at the same time, through the extrusion deformation of the spring B63 and the elastic pleated oil storage bag 4, the oil cylinder can be rotated and installed. The contraction of the folds of the wrinkled oil storage bag 4 greatly reduces the amplitude of the cylinder and enhances the stability of the cylinder. When the elastic wrinkled oil storage bag 4 is compressed, the lubricating oil inside it has a damping effect on the elastic wrinkled oil storage bag 4 on the one hand, and on the other hand, part of the oil enters the annular flow channel 3a through the oil guide pipe 43, and is diverted from the annular flow channel 3a to the drainage hole 3b, thereby lubricating the shaft rod 7 mounted on the two shaft rod brackets 3, which can not only lubricate the shaft rod 7 but also dissipate heat from it, greatly improving the stability of the connection between the cylinder and the shaft rod 7.
