Detailed Description

The present invention will be further described with reference to the accompanying drawings.

One embodiment of this solution is shown in fig. 1, and includes cylinder 1 and bellows 2, wherein bellows 2 nests in cylinder 1. The cylinder barrel 1 and the corrugated pipe 2 are both provided with an opening at one end and a closed end at the other end, and the opening ends of the cylinder barrel 1 and the corrugated pipe 2 are fixedly connected together, so that a closed oil storage cavity 3 is formed between the cylinder barrel 1 and the corrugated pipe 2. The closed end of the cylinder barrel 1 is respectively provided with an oil delivery port and an exhaust port which are communicated with the oil storage cavity 3.

A push rod 4 is arranged in the bellows 2. One end of the push rod 4 is fixed to the closed end of the bellows 2, and the other end thereof extends to the outside of the cylinder. The longitudinal section of the pipe wall of the corrugated pipe 2 is corrugated, and the pipe body of the corrugated pipe 2 can be compressed and bent, so that the push rod 4 is driven to change together when the pipe body is changed.

A return spring 5 is sleeved on the push rod 4. One end of return spring 5 abuts against the closed end of bellows 2, and the other end is confined within bellows 2 by a flange 6.

The flange 6 is structured as shown in fig. 3, a rod hole is arranged in the middle of the flange, and the flange 6 is sleeved on the push rod 4 and fixed at the opening end of the cylinder barrel 1.

The specific structure of the cylinder barrel 1 is shown in fig. 2, and the opening end of the cylinder barrel 1 is provided with a cylinder barrel inner edge 11 and a cylinder barrel outer edge 12.

The edge 11 is the annular in the cylinder, and its inner ring diameter and bellows 2's open end diameter phase-match, on the edge 11 in the fixed cylinder of bellows 2's open end.

The outer edge 11 of the cylinder barrel and the flange 6 are provided with a plurality of matched screw holes 13 which are fixed together through a plurality of locking bolts 71.

In addition, a matched pressure plate 7 is arranged on the outer side of the flange 6, the structure of the pressure plate 7 is shown in fig. 5, the structure of the pressure plate 7 is the same as that of the flange 6, a plurality of screw holes 13 matched with the outer edge 12 of the cylinder barrel are also arranged on the pressure plate 7, and the pressure plate and the flange 6 are fixed on the outer edge 12 of the cylinder barrel through locking bolts 71.

A nut 61 is provided between the flange 6 and the pressure plate 7, the nut 61 being mounted on the locking bolt 71. The nut 61 can ensure the reliability of the locking bolt 71 and can effectively prevent the flange 6 from loosening in long-term operation.

In addition, the push rod 4 is provided with threads, thereby facilitating a fixed connection with an external device.

Furthermore, a sealing cap is provided on both the oil supply opening 8 and the exhaust opening 9, by which the opening is closed when not in use. The oil delivery port 8 and the exhaust port 9 have the same structure, and in practical use, one of the oil delivery port and the exhaust port can be defined as the oil delivery port 8, and the other can be defined as the exhaust port 9.

The use principle of the scheme is as follows:

when the hydraulic oil filling device is used for the first time, the sealing caps above the oil conveying port 8 and the exhaust port 9 are respectively taken down, then hydraulic oil is slowly injected from the oil conveying port 8, so that air in the oil storage cavity 3 is slowly discharged from the exhaust port 9, and after the hydraulic oil is injected, the sealing caps are adopted to seal the exhaust port 9, so that normal use can be started.

When the oil cylinder is used, when hydraulic oil is further injected into the oil delivery port 8 through high pressure, the oil body compresses the corrugated pipe 2 to enable the pipe body to be compressed and changed, and therefore the push rod 4 is pushed to linearly push towards the outside of the cylinder barrel.

Because the tube body of the corrugated tube 2 can be compressed and bent, when the push rod 4 is restrained by external force to deflect the tube body, the tube body of the corrugated tube 2 can also be compressed and deflected obliquely, so that the push rod 4 can be pushed in multiple directions.

Fig. 6 shows the push rod 4 in the upward deflected and pushed state, and it can be seen that the bellows 2 is extended on one side of the wall and compressed on the other side so as to be adapted to the deflected direction of the push rod 4.

Fig. 7 shows a schematic view of the pusher in a state of pushing opposite to the direction of fig. 6, in which the pusher 4 is deflected to push downward. Whereas the wall variation of bellows 2 is the opposite of that of figure 6.

When the oil pressure in the oil storage cavity is reduced, the corrugated pipe 2 is reset under the elastic force action of the reset spring 5, so that the push rod 4 is driven to complete the contraction action.

Compared with the existing hydraulic oil cylinder structure, the hydraulic oil cylinder structure has the advantages that the multi-direction propelling function of the push rod is realized, the sealing structure of the oil storage cavity 3 is easy to realize, the technological requirements on manufacturing and machining are low, the manufacturing cost is low, the fault is not prone to occurring in the working process, and the hydraulic oil cylinder structure is more stable and reliable.

It will be understood by those skilled in the art that the present solution is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principles of the solution, but that various changes and modifications may be made to the solution without departing from the spirit and scope of the solution, and these changes and modifications are intended to be within the scope of the claimed solution.
