Abstract
The utility model discloses an air pressure double-way inside-outside sealing leather cup which is formed by combining the bottom portions of two single-way sealed leather cups with inside-outside sealed openings in a back-against-back mode in a manufacturing mode. An annular groove with a trapezoidal or after-fillet-trapezoidal section is formed in the inner surface and the outer surface of a circular body of the leather cup. Annular grooves are formed at two ends of the leather cup. The shape of the section of the leather cup is formed by connecting two groups of horizontally-connected lower ends of two Ys. The outline of the surface is in a circular shape. After the air pressure double-way inside-outside sealing leather cup which is simple in structure and convenient to manufacture is used, the problem that two leather cups are arranged on one piston to achieve double-way sealing is avoided, parts are reduced, size is reduced, and cost is lowered.
Description
Technical field
The utility model relates to the two-way inside and outside sealing cup of a kind of air pressure for pressure system.
Background technique
The leather cup that uses now is all one-way sealing basically, causes leather cup can not play seal action when mobile to opposite direction.
Summary of the invention
The purpose of this utility model be to provide in a kind of cylinder body in pressure system forward and when oppositely mobile, can both play the leather cup of seal action.
For achieving the above object, the two-way inside and outside sealing cup of described the utility model air pressure, it is characterized in that: the two-way inside and outside sealing cup of air pressure is that the bottom with the leather cup of two one-way sealings that inside and outside sealing oral area arranged leans against privately and is manufactured in together, trapezoidal circular groove after having the cross section to be trapezoidal or fillet on the inner and outer surface on the circular body of leather cup, there is annular groove at the two ends of leather cup; The shape in the cross section of leather cup by two "
Y" two groups of compositions laterally linking together of lower end, the profile on surface is circular.
For the sealed mouth that makes the two-way inside and outside sealing cup of air pressure has elasticity, the two-way inside and outside sealing cup of the described the utility model air pressure resilient rubber of apparatus is during fabrication made.
In order to increase the sealing of leather cup when positive and negative direction moves, the diameter of the sealed mouth end of the positive and negative direction of the two-way inside and outside sealing cup of described the utility model air pressure is consistent.
Inside and outside the utility model air pressure is two-way, sealing cup is simple in structure, easily manufactured, after adopting the two-way inside and outside sealing cup of air pressure, has avoided filling two leather cups and carry out two way sealed on a piston, has reduced accessory, has dwindled volume, has reduced cost.

Fig. 1 is the form structure schematic diagram of the plan view of the two-way inside and outside sealing cup of the utility model air pressure when keeping flat.
Fig. 2 is the structural representation of the sectional view of the two-way inside and outside sealing cup of the utility model air pressure.
Embodiment
The two-way inside and outside sealing cup of the utility model air pressure is that the bottom with the leather cup of two one-way sealings that inside and outside sealing oral area arranged leans against privately and is manufactured in together, trapezoidal circular groove after having the cross section to be trapezoidal or fillet on the inner and outer surface on the circular body of leather cup, there is annular groove at the two ends of leather cup; The shape in the cross section of leather cup by two "
Y" two groups of compositions laterally linking together of lower end, the profile on surface is circular.
For the sealed mouth that makes the two-way inside and outside sealing cup of air pressure has elasticity, the resilient rubber of apparatus is made during fabrication.In order to increase the sealing of leather cup when positive and negative direction moves, the diameter of the sealed mouth end of the positive and negative direction of the two-way inside and outside sealing cup of air pressure is consistent.
The two-way inside and outside sealing cup of the utility model air pressure is arranged in the cylinder body or valve body that need to carry out two way sealed, the external sealed oral area of the two-way inside and outside sealing cup of air pressure contacts with the inwall of cylinder body or valve body, and the interior sealing oral area of the two-way inside and outside sealing cup of air pressure is enclosed within on post or bar.After pressurized gas entered cylinder body or valve body one end interior, pressurized gas promoted that the two-way inside and outside sealing cup of air pressure moves forward, promotes post or bar moves and works.After pressurized gas entered in cylinder body or valve body from the opposite direction the other end of cylinder body or valve body, pressurized gas was from promoting the two-way inside and outside sealing cup of air pressure in the other direction, and the two-way inside and outside sealing cup of air pressure moves backward, promotes post or bar also moves backward and works.
When the two-way inside and outside sealing cup of the utility model air pressure is used for the air pressure telescopic cylinder, a two-way inside and outside sealing cup of air pressure only being installed on plunger rod in body one by one, both reduced an annular groove of plunger rod, reduced again by a leather cup.
