Disclosure of Invention
The utility model aims to solve the technical problem of providing a novel hydraulic push rod which can accurately adjust the flow velocity of a piston and has long service life.
The utility model relates to a novel hydraulic push rod, which comprises an upper end cover and a lower end cover, wherein a cylinder body is arranged between the upper end cover and the lower end cover, a piston is arranged in the cylinder body, the piston is connected with the push rod, hydraulic oil channels and needle valves are respectively processed on the upper end cover and the lower end cover, the two hydraulic oil channels are respectively led to the end face of one side of the piston, and an oil passing ring is arranged between the upper end cover and the lower end cover and between the upper end cover and the cylinder body.
The utility model relates to a novel hydraulic push rod, wherein an upper end cover and a lower end cover are fixedly connected with a cylinder body through a screw rod.
The utility model relates to a novel hydraulic push rod, wherein a connecting flange is arranged on the outer side of an upper end cover.
The utility model relates to a novel hydraulic push rod, wherein a waterproof ring is arranged in the middle of the end face of an upper end cover.
The utility model relates to a novel hydraulic push rod, wherein the push rod passes through the middle part of a waterproof ring.
The utility model relates to a novel hydraulic push rod, wherein a sealing ring is arranged in an upper end cover.
The novel hydraulic push rod is sleeved outside the push rod, and a gap between a hydraulic oil channel in an upper end cover and the push rod is closed.
The novel hydraulic push rod disclosed by the utility model is different from the prior art in that the speed of the piston action can be regulated through the needle valve, and meanwhile, the service life of the piston is prolonged through the smoothness of the oil ring and the piston when the piston is opened and closed.

Detailed Description
The following examples are illustrative of the utility model and are not intended to limit the scope of the utility model.
As shown in fig. 1 and 2, the novel hydraulic push rod 6 comprises an end cover 1, wherein the end cover comprises an upper end cover and a lower end cover, a cylinder body 2 is arranged between the upper end cover and the lower end cover, and the upper end cover and the lower end cover are fixedly connected with the cylinder body 2 through screws.
The cylinder body 2 is internally provided with a piston 3, the piston 3 is connected with a push rod 6, and one end of the push rod 6 extends out from one side of the upper end cover.
The upper end cover and the lower end cover are respectively provided with a hydraulic oil channel, the two hydraulic oil channels are respectively communicated with the end face at one side of the piston 3, and the reciprocating motion of the piston 3 and the push rod 6 is realized through the flow of hydraulic oil at two sides.
Needle valve 4 is still installed respectively to one side of upper end cover and lower end cover, and needle valve 4 can finely adjust hydraulic oil velocity of flow, and then adjusts piston 3 speed, and the velocity of flow when opening and close with piston 3.
An oil passing ring is arranged between the upper end cover and the lower end cover and the cylinder body 2, so that the hydraulic oil can smoothly flow when the piston 3 is closed, the stability of the piston 3 during operation is ensured, and the piston 3 is prevented from being damaged. The service life of the piston 3 is prolonged.
The connecting flange 5 is installed in the outside of upper end cover, and connecting flange 5 passes through screw rod and upper end cover fixed connection. The waterproof ring 8 is arranged in the middle of the end face of the upper end cover, and the push rod 6 passes through the waterproof ring 8 and the middle of the connecting flange 5. The inside sealing washer 7 that is provided with of upper end cover, sealing washer 7 cover are in the push rod 6 outside, seal the gap between hydraulic oil passageway and the push rod 6 in the upper end cover.
When the novel hydraulic push rod 6 is used, the novel hydraulic push rod 6 is fixedly connected with external equipment through the connecting flange 5, the hydraulic oil channels on the upper end cover and the lower end cover are respectively connected with a hydraulic system, and the piston 3 and the push rod 6 are driven to move by adjusting the pressure of hydraulic oil in the two hydraulic oil channels, so that the function of the hydraulic push rod 6 is realized.
According to the novel hydraulic push rod, the speed of the piston action can be regulated through the needle valve, and meanwhile, the service life of the piston is prolonged through the oil ring and the stability of the piston when the piston is opened and closed.
