Description

Novel hydraulic oil cylinder

Technical Field

The utility model relates to a hydraulic cylinder field specifically is a novel hydraulic cylinder.

Background

The hydraulic oil cylinder is a hydraulic actuating element which converts hydraulic energy into mechanical energy and makes linear reciprocating motion. The hydraulic system is widely applied to hydraulic systems of various machines. When the hydraulic cylinder in the front works, the plunger has impact with certain strength on the cylinder body, and certain damage can be caused for a long time, so that certain improvement needs to be carried out on the inside of the cylinder body to protect the long-time use of the hydraulic cylinder.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model discloses a novel hydraulic cylinder.

The technical scheme of the utility model is that: the utility model provides a novel hydraulic cylinder, comprising a cylinder body, the hydraulic fluid port has been seted up to a cylinder body side proximal end position, be equipped with the plunger in the cylinder body, the position that the plunger is close the hydraulic fluid port is equipped with the operation inner chamber, the stroke stopper that is equipped with looks adaptation with it in the operation inner chamber, one side bottom that the plunger was kept away from to the stroke stopper is equipped with the spacing ring, be equipped with the spring between spacing ring and the plunger bottom, be equipped with the big oil passage way of leading to in the stroke stopper and be located the little oil passage way that leads to in big oil passage way one side, the big oil passage way that leads to is cylindrical inner chamber, little oil passage way is conical inner chamber, the stroke stopper outside is equipped with spacing recess, be equipped with the stopper with spacing recess looks adaptation on the plunger.

Further, the length of the limiting groove along the direction of the travel plug is smaller than the distance between the limiting block and the inner side wall of the plunger travel inner cavity.

Further, the length of the limiting groove in the direction of the travel plug is smaller than the maximum length of the spring in the extension state.

Further, the oil port is located on one side of the spring in a compressed state, which is far away from the bottom of the plunger.

Furthermore, the conical diameter of the small oil through channel is consistent with the length of the cylindrical diameter of the large oil through channel, and the conical tip of the small oil through channel is positioned on one side close to the limiting ring.

Further, the diameter of the stop collar is the same as the maximum diameter of the plunger.

The utility model discloses an useful part: this application simple structure is through setting up the stroke stopper in the plunger to establish logical oil passageway and spacing recess respectively in the inside and the outside of stroke stopper, establish the spring in the spacing ring, effectively play the guard action to the plunger, prevent to cause the rigidity to destroy to the cylinder body.
