Description
Technical Field
The utility model relates to a sealing member, concretely relates to rodless cylinder piston sealing member.
Background
The piston in the rodless cylinder is sealed with the cylinder barrel and the sealing strip through the sealing ring, so that the reciprocating movement of the sliding block connected to the piston is driven.
As shown in fig. 4: when the sealing ring 10 is in contact with the inner wall of the cylinder barrel 8 and the sealing strip 7, the borne pressure is different, namely, the pressure generated by the sealing strip 7 on the sealing ring is greater than the pressure generated by the inner wall of the cylinder barrel on the sealing strip, and the matching stability between the sealing strip and the sealing strip is poor, meanwhile, because the traditional sealing strip structure is simple, the piston is caused to be in the frequent moving process, the contact part of the sealing strip and the sealing strip is easy to generate the phenomenon of fatigue, the supporting force on the sealing strip is not enough, the deformation at the contact part is excessive, the sealing strip is drooped, the leakage problem is generated, and therefore, the improved space exists in the sealing ring used in the rodless.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a rodless cylinder piston sealing member strengthens the structural strength of sealing washer and sealing strip contact site to show and improve sealed effect.
In order to achieve the above purpose, the utility model provides a following technical scheme:
the utility model provides a rodless cylinder piston seal spare, includes the sealing washer, and the shaping has the seal lip on the lateral wall of sealing washer to and form recess, characterized by between the lateral wall of seal lip and sealing washer:
two reinforcing walls are formed in the groove, two sides of each reinforcing wall are respectively connected with the inner wall of the sealing lip and the outer wall of the sealing ring, and the lip part between the two reinforcing walls forms a sealing support part;
and a supporting wall is formed at one end of the sealing ring, which faces away from the groove, and corresponds to the sealing supporting part.
Preferably, the reinforcing wall is integrally formed with the seal ring and the lip.
Preferably, the inner wall of the sealing ring has an inclined necking section.
As a preferable solution of this embodiment, the outer side wall of the sealing lip has a plurality of ring grooves.
As a preferable aspect of this embodiment, the seal support portion has a support plane thereon.
The utility model has the advantages that:
1. the sealing support part is contacted with the sealing strip, and due to the arrangement of the reinforcing wall, the structural strength of the sealing support part is obviously improved, and the problems that the sealing strip is sagged and leaks due to excessive deformation caused by fatigue of the sealing element are avoided;
2. the supporting wall can support the sealing strip, and further prevent that the sealing strip from taking place flagging problem.

Detailed Description
The rodless cylinder piston seal of the present invention is further described with reference to fig. 1 to 3.
The utility model provides a rodless cylinder piston sealing member, includes sealing washer 1, and the shaping has seal lip 2 on the lateral wall of sealing washer 1 to and form recess 3 between seal lip 2 and the lateral wall of sealing washer 1, and the setting of this seal lip can show the sealed effect that promotes whole sealing member.
Two reinforcing walls 6 are formed in the groove 3, two sides of each reinforcing wall 6 are respectively connected with the inner wall of the sealing lip 2 and the outer wall of the sealing ring 1, and a lip part between the two reinforcing walls 6 forms a sealing support part 9;
and a supporting wall 4 is formed at one end of the sealing ring 1, which is back to the groove 3, and the supporting wall 4 corresponds to the sealing supporting part 9.
This embodiment is when specifically using, under the assembly structure promptly, sealing support portion 9 and sealing strip 7 contact to can remove for the sealing strip, because strengthen the setting of wall 6, show the structural strength who has promoted sealing support portion 9, improve the support intensity to the sealing strip, avoid the sealing member to take place tired soft, lead to deformation excessive, lead to the sealing strip 7 flagging, lead to the fact the problem of revealing. When the sealing support part is in sealing fit with the sealing strip, the supporting wall 4 can support the sealing strip 7, and further the problem that the sealing strip 7 sags is solved.
The embodiment is further configured as follows: the reinforcing wall 6 is formed integrally with the sealing ring 1 and the sealing lip. Under the integrated into one piece structure, stable in structure, sealed effectual, and production is convenient.
The embodiment is further configured as follows: the inner wall of the sealing ring 1 has an inclined constriction 5. The inclined necking section 5 can clamp the piston, and the sealing effect between the sealing ring and the piston is improved.
The embodiment is further configured as follows: the outer side wall of the sealing lip 2 is provided with a plurality of ring grooves 21. The ring groove is arranged, so that the flexibility and toughness of the lip can be improved, the deformation of the sealing ring 1 in the moving process can be facilitated, and the effective sealing effect can be achieved.
The embodiment is further configured as follows: the seal support portion has a support plane 41 thereon. This supporting plane can promote the roughness with sealing strip 7 contact, improves the stability of complex between the two and leakproofness.
The embodiment is further configured as follows: this supporting plane is the tilt state setting, and this tilt state can be with the inseparabler of sealing strip laminating to with the sealing strip direction support wall, make the sealing strip cross the steady support behind the supporting plane on the support wall, with further promotion complex leakproofness.
