Description
Technical Field
The utility model relates to a no bottle pushes away jar technical field, especially relates to a no bottle pushes away jar overall structure.
Background
The electric cylinder is a brand new revolutionary product for realizing high-precision linear motion series. The electric cylinder is also called as an electric cylinder, the electric cylinder mainly replaces an air cylinder, but the electric control is more convenient, the electric cylinder is applied to industrial equipment, and the thrust can be realized from 10kg to 100 tons in door opening, lifting and pushing.
The existing push cylinder has the following problems: 1. a sealing element is often used for sealing between the piston rod and the cylinder body, and the requirement on the design of the cylinder barrel is high; 2. the front cavity and the rear cavity of the oil cylinder are relatively separated, so that an energy storage device needs to be additionally arranged; 3, the rear end cover is provided with an oil inlet, and after oil or gas is added through the oil filling port, the oil inlet is blocked. Therefore, the integral structure of the bottle-free push cylinder is provided.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defect that the cylinder body structure of the electric cylinder in the prior art has design defects, and providing a non-bottle push cylinder overall structure.
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 overall structure, includes outer cylinder, interior cylinder, piston rod, front end housing and rear end cap, the inside of outer cylinder is provided with interior cylinder, and the front end of outer cylinder is provided with the front end housing, and the rear end of outer cylinder is provided with the rear end cap, and the center of interior cylinder is pegged graft and is had the piston rod, and the piston rod runs through the front end housing extends to the outside of front end housing, set up out the opening on the front end housing.
Preferably, the inner cylinder barrel is arranged in the outer cylinder barrel, and the inner cylinder barrel is in sliding fit with the outer cylinder barrel.
Preferably, the inner space of the outer cylinder barrel is divided into two sections of cavities by the inner cylinder barrel, wherein the cavity space close to the front end cover is designed as a front oil cylinder cavity, and the cavity space close to the rear end cover is designed as a rear oil cylinder cavity.
Preferably, the port is used for filling oil or gas.
The utility model has the advantages that: through the whole mechanism of the electric cylinder, the problem that the cylinder body structure of the electric cylinder has design defects is solved, the electric cylinder is sealed without a sealing element, the front cavity of the oil cylinder is kept conducted with the rear cavity, and the oil inlet is not formed in the rear end cover.
Drawings
Fig. 1 is a schematic view of the overall structure of the non-bottle pushing cylinder provided by the utility model.
In the figure: 1 piston rod, 2 inner cylinder, 3 outer cylinder, 4 front end covers, 5 rear end areas, 6 through openings, 7 oil cylinder front cavities and 8 oil cylinder rear cavities.
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.
In this embodiment, referring to fig. 1, a no bottle pushes away jar overall structure, including outer cylinder 3, inner cylinder 2, piston rod 1, front end housing 4 and rear end cap 5, place in outer cylinder 3 in inner cylinder 2, inner cylinder 2 and outer cylinder 3 sliding fit, the front end of outer cylinder 3 is provided with front end housing 4, the rear end of outer cylinder 3 is provided with rear end cap 5, the inner space of outer cylinder 3 is separated into two sections cavitys by inner cylinder 2, wherein, the cavity space design that is close to front end housing 4 is hydro-cylinder front chamber 7, the cavity space design that is close to rear end housing 5 is hydro-cylinder rear chamber 8, the center of inner cylinder 2 is pegged graft and is had piston rod 1, piston rod 1 runs through front end housing 4 and extends to the outside of front end housing 4, division out opening 6 on the front end housing 4, opening 6 is used for refueling or the air entrainment.
The piston of the pushing cylinder is sealed without a sealing element, the front cavity and the rear cavity of the oil cylinder are kept conducted, the oil inlet is not formed in the rear end cover any more, the design requirement of the inner wall of the cylinder barrel is reduced when the pushing cylinder is used, an energy storage device does not need to be additionally configured, the structure is simple and compact, and the installation space is reduced.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
