Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

Example (b):

referring to fig. 1 and 2, the present embodiment provides an oil cylinder with a convenient oil path, including a cylinder body 1, a piston 2 disposed in the cylinder body 1, a piston rod 3 disposed in the cylinder body 1 and fixedly connected to the piston 2, and a cylinder base 4 disposed at the bottom of the cylinder body 1, wherein the cylinder body 1 is divided into a first oil chamber 13 and a second oil chamber 14 by the piston 2, in other words, the first oil chamber 13 and the second oil chamber 14 are respectively disposed at the upper side and the lower side of the piston 2.

A first oil way 11 and a second oil way 12 are arranged on the cylinder body 1; the cylinder seat 4 is provided with a third oil path 41 and a fourth oil path 42;

one end of the first oil path 11 is communicated with the first oil chamber 13, and the other end is communicated with one end of the third oil path 41; the other end of the third oil path 41 is an oil port a 411; in this way, the hydraulic oil enters the third oil passage 41 from the oil port a411, enters the first oil passage 11 from the third oil passage 41, and finally enters the first oil chamber 13 from the first oil passage 11 to drive the piston 2 and the piston rod 3 to move.

In order to improve the sealing performance of the connection end of the first oil passage 11 and the third oil passage 41; in this embodiment, a seal ring 44 is fitted to the connection end of the first oil passage 11 and the third oil passage 41, and the sealing performance is ensured by the seal ring 44.

In the present embodiment, one end of the second oil passage 12 communicates with the second oil chamber 14, and the other end communicates with one end of the fourth oil passage 42; the other end of the fourth oil passage 42 is a port b 421. In this way, the hydraulic oil enters the fourth oil passage 42 from the oil port b421, enters the second oil passage 12 from the fourth oil passage 42, and finally enters the second oil chamber 14 from the second oil passage 12 to drive the piston 2 and the piston rod 3 to move. Similarly, in order to improve the sealing property of the connection end of the second oil passage 12 and the fourth oil passage 42; in this embodiment, a seal ring 44 is also fitted at the connection end of the second oil passage 12 and the fourth oil passage 42.

In order to adapt to the variety of oil pipe routing of the connecting oil port, in this embodiment, as shown in fig. 3, the bottom of the cylinder base 4 is provided with an accommodating cavity 40; the oil port a411 and the oil port b421 are both positioned on the bottom wall of the accommodating cavity 40; and the side walls at the two sides of the bottom of the cylinder seat 4 are provided with side openings 43 communicated with the accommodating cavity 40.

Through the arrangement, when the oil pipe needs to be directly routed from the bottom of the cylinder seat 4, the oil pipe only needs to be connected to the oil port a 411/the oil port b421, and the oil pipe directly penetrates out.

Sometimes, the cylinder seat 4 may need to be directly installed in a bottom-seated manner, at this time, the bottom wall of the cylinder seat 4 is shielded, and the oil pipe cannot be directly routed, so that lateral routing can be adopted, that is, one end of the oil pipe is connected to the oil port a 411/the oil port b 421; the other end of the tube extends out of the side opening 43 to accommodate the installation environment.
