Technical Field

The utility model relates to a push away jar technical field, especially relate to a no bottle pushes away jar rear end cap.

Background

The cylinder is composed of piston rod, cylinder barrel, front end cover and back end cover, and features simple structure, reliable operation, no need of speed reducer and no transmission gap.

An oil inlet is formed in a rear end cover of a push cylinder in the prior art, so that the tightness is reduced, and the requirement on the precision of the rear end cover is relatively high, so that an improved rear end cover is urgently needed to solve the problem.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problems in the prior art and providing a rear end cover of a non-bottle pushing cylinder.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a no bottle pushes away jar rear end cap, includes the lid, the constant head tank has been seted up to one side of lid, and the constant head tank is including first ring channel, second ring channel, third ring channel and fourth ring channel, and first ring channel, second ring channel, third ring channel and fourth ring channel are from the left right side and distribute the setting to interconnect becomes integrative between first ring channel, second ring channel, third ring channel and the fourth ring channel, and the inner wall of constant head tank is provided with the sealing strip, and the reentrant corner has all been seted up to the outer wall both sides of lid.

Preferably, the inner wall and the outer wall of the cover body are both in a sealing structure.

Preferably, the sealing strip is fixed on one side of the inner wall of the positioning groove through glue, and the sealing strip is made of silicon rubber.

Preferably, the shape and the size of the sealing strip are matched with those of the positioning groove, and the sealing strip is tightly attached to the first annular groove, the second annular groove, the third annular groove and the fourth annular groove.

Preferably, the positioning groove is matched with the rear cavity of the oil cylinder.

Preferably, the pitches of the first annular groove, the third annular groove, the second annular groove and the fourth annular groove decrease in sequence.

Compared with the prior art, the utility model discloses changed the rear end cap structure of general hydro-cylinder, set it to the structure of no oil inlet, not only simple structure, greatly reduced moreover to the requirement of precision.

fig. 2 is a front view of the rear end cap of the non-bottle pushing cylinder provided by the utility model.

In the figure: 1 rear end cover, 11 locating grooves, 111 first annular groove, 112 second annular groove, 113 third annular groove, 114 fourth annular groove, 12 reentrant angles and 2 sealing strips.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a bottle-free rear end cover of a cylinder, including a cover body 1, a positioning groove 11 adapted to a rear cavity of the cylinder is provided on one side of the cover body 1, the positioning groove 11 includes a first annular groove 111, a second annular groove 112, a third annular groove 113 and a fourth annular groove 114, the first annular groove 111, the second annular groove 112, the third annular groove 113 and the fourth annular groove 114 are distributed from left to right, and the first annular groove 111, the second annular groove 112, the third annular groove 113 and the fourth annular groove 114 are connected with each other into a whole, a sealing strip 2 made of silicon rubber is provided on an inner wall of the positioning groove 11, the sealing strip 2 is used for sealing the cover body 1 and the rear cavity of the cylinder, and a concave angle 12 is provided on both sides of an outer wall of the cover.

The inner wall and the outer wall of the cover body 1 are both sealing structures, the sealing strip 2 is fixed on one side of the inner wall of the positioning groove 11 through glue, the shape and the size of the sealing strip 2 are matched with those of the positioning groove 11, the sealing strip 2 is tightly attached to the first annular groove 111, the second annular groove 112, the third annular groove 113 and the fourth annular groove 114, and the distances between the first annular groove 111, the third annular groove 113, the second annular groove 112 and the fourth annular groove 114 are reduced in sequence.

In this embodiment, during the assembly, cover body 1 in the hydro-cylinder back cavity for constant head tank 11 pastes with the hydro-cylinder back cavity mutually, and sealing strip 2 is tightly arranged in between the lateral wall of cover body 1 and the lateral wall of hydro-cylinder back cavity simultaneously.

To sum up, the utility model discloses a no bottle pushes away jar rear end cap has changed general hydro-cylinder and has had the structure of hydraulic fluid port, sets it to the structure of no oil inlet, not only simple structure, greatly reduced moreover to the requirement of precision.
