Abstract
The utility model discloses a kind of two way seal leather cup, including interconnecting piece, sealing, sealing ring and reinforcing rib, interconnecting piece both ends are symmetrically connected with sealing；The sealing includes sealed sides, connecting side and sealing surface, and being horizontally disposed on the sealing surface has several sealing rings, and several reinforcing ribs are provided between the sealed sides of the sealing.Advantage is that two sealings of the utility model may be implemented to seal, and traditional obturating cup can only one-way sealing then need two one-way sealing bowls being reversed to two way seal, the quantity of parts is increased, and the utility model only needs one two way seal can be completed.Being horizontally disposed on sealing surface has several sealing rings, further increases the sealability of sealing surface.It is provided with several reinforcing ribs between the sealed sides of sealing, can not only increase the intensity of leather cup, while reinforcing rib also acts the effect of support sealing, enhance cup packing ability.
Description
Technical field
The utility model is related to technical field of automobile parts, more particularly to a kind of two way seal leather cup.
Background technology
Existing sealing cup is nearly all one-way sealing, can only realize the sealing in a direction, but in piston cylinder
It either needs to seal the both sides of piston or spool in certain valves, if it is realized using existing sealing cup close
Envelope, then need two unidirectional leather cups being reversed that could complete, not only amount of parts caused to increase, but also also need to increase
Additional leather cup card slot.Existing cup packing face is plane simultaneously, and flexible deformation is insufficient, causes cup packing performance bad
Disadvantage.
Utility model content
The technical problem to be solved by the present invention is to provide one kind, and two way seal may be implemented, and good seal performance is double
To sealing cup.
The technical solution of the utility model is：
A kind of two way seal leather cup, including interconnecting piece, sealing, sealing ring and reinforcing rib, interconnecting piece both ends symmetrically connect
It is connected to sealing；The sealing includes sealed sides, connecting side and sealing surface, be horizontally disposed on the sealing surface have it is several close
Seal ring is provided with several reinforcing ribs between the sealed sides of the sealing.
Further, reinforcing rib bottom surface is arc-shaped.
Further, the bottom surface circular arc of reinforcing rib and the sealed sides of sealing are tangent.
Further, sealing ring is at least 3.
Further, the sealed sides cross section of sealing is arc.
The utility model is beneficial in that：
The utility model interconnecting piece both ends are symmetrically connected with sealing, and two sealings may be implemented to seal, and pass
The obturating cup of system can only one-way sealing, it is certain need carry out two way seal piston cylinders or valve interior sealing performance it is weaker,
To two way seal, then two one-way sealing bowls being reversed are needed, increases the quantity of parts, and the utility model is only
Need one two way seal can be completed.Being horizontally disposed on sealing surface has several sealing rings, further increases sealing surface
Sealability.It is provided with several reinforcing ribs between the sealed sides of sealing, can not only increase the intensity of leather cup, reinforce simultaneously
Muscle also acts the effect of support sealing, enhances cup packing ability.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the Section A-A structural schematic diagram in Fig. 1.
In figure：1- interconnecting pieces, 2- sealings, 21- sealed sides, 22- connecting sides, 23- sealing surfaces, 3- sealing rings, 4- reinforce
Muscle.
Specific implementation mode
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figs. 1-2：
A kind of two way seal leather cup, including interconnecting piece 1, sealing 2, sealing ring 3 and reinforcing rib 4,1 both ends of interconnecting piece are right
Title is connected with sealing 2；The sealing 2 includes sealed sides 21, connecting side 22 and sealing surface 23, horizontal on the sealing surface 23
It is provided with several sealing rings 3, several reinforcing ribs 4 are provided between the sealed sides 21 of the sealing 2.
Specifically, in order to increase the intensity of reinforcing rib 4,4 bottom surface of reinforcing rib is arc-shaped.
Specifically, in order to increase the elasticity of reinforcing rib 4, the bottom surface circular arc of reinforcing rib 4 and 21 phase of sealed sides of sealing 2
It cuts.
Specifically, in order to ensure that sealing effect, sealing ring 3 are at least 3.
Specifically, in order to increase the elasticity of sealing 2,21 cross section of sealed sides of sealing 2 is arc.
1 both ends of the utility model interconnecting piece are symmetrically connected with sealing 2, and two sealings 2 may be implemented to seal, and
Traditional obturating cup can only one-way sealing, it is certain need carry out two way seal piston cylinders or valve interior sealing performance compared with
It is weak, to two way seal, then two one-way sealing bowls being reversed are needed, increases the quantity of parts, and this practicality is new
Type only needs one two way seal can be completed.Being horizontally disposed on sealing surface 23 has several sealing rings 3, further increases close
The sealability of cover 23.Several reinforcing ribs 4 are provided between the sealed sides 22 of sealing 2, can not only increase leather cup
Intensity, while reinforcing rib 4 also acts the effect of support sealing 2, enhances cup packing ability.
The embodiment of the utility model is explained in detail above in association with attached drawing, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the scope of protection of the utility model.
