Abstract

The utility model discloses a seal member comprising a hard baffle ring and a sealing assembly. The upper and lower ends of the baffle ring are both accommodated in an accommodating groove of the sealing assembly; and the sealing assembling is disposed in the accommodating groove. When two mechanical member end surfaces are sealed via the seal member, the two mechanical member end surfaces are pushed against the end surface of the baffle ring till the end surfaces stop, so the seal member cannot be damaged due to pressure.

Description

A kind of Sealing

Technical field

The utility model relates to a kind of Sealing.

Background technique

For end-to-end link mechanical part, in order to guarantee that two mechanical parts connect between its end face and have good sealability, Sealing need to be set between both ends of the surface, general Sealing is O type circle.

Between two mechanical parts, generally by forms such as bolts, realize and interconnecting, this Placement cannot be predicted the pressure size of two mechanical parts to Sealing, if it is too tight that two mechanical parts connect, easily cause its end face pressure break O type circle, thereby affect sealing effect; If two mechanical parts connected pine, easily cause O type circle not fit tightly the both ends of the surface of mechanical part, also can affect sealing effect.Therefore be necessary existing Sealing to improve.

Summary of the invention

For the deficiencies in the prior art, the utility model provides a kind of Sealing.

The utility model is achieved by the following technical solution: a kind of Sealing, and comprise and back-up ring and the black box of hard, at the upper and lower two ends of described back-up ring, the receiving groove that holds described black box is all set, described black box is set in described receiving groove.

In technique scheme, described receiving groove has the sidewall of circular arc.

The utlity model has following beneficial effect: in the process two mechanical part end faces being sealed by the utility model Sealing, two mechanical part end faces stop while leaning to described back-up ring end face, therefore can not produce the situation of damaging Sealing by pressure.

Accompanying drawing explanation

Fig. 1 is schematic top plan view of the present utility model.

Fig. 2 is cross-sectional schematic of the present utility model.

Fig. 3 is another embodiment's of the utility model cross-sectional schematic.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail, embodiment 1: referring to Fig. 1 to Fig. 2, a kind of Sealing, the back-up ring 1 and the black box 2 that comprise hard, at described back-up ring, Shang Xia 1, the receiving groove 10 that holds described black box 2 is all set two ends, described black box 2 is set in described receiving groove 10.

In the process that two mechanical part end faces are sealed, two mechanical part end faces stop while leaning to described back-up ring 1 end face, now cannot continue to press down two mechanical parts, therefore can not produce the situation of damaging black box 2 by pressure.

Embodiment 2: referring to Fig. 3, described receiving groove 10 has the sidewall of circular arc, embodiment 2 all the other with embodiment 1, when black box 2 stress deformation, there is the shape of fitting with the receiving groove 10 of circular arc sidewall, guaranteed that black box 2 can be fixed in described receiving groove 10 comparatively reliably.Embodiment's 2 working principles, with embodiment 1, do not repeat them here.

Claims

1. a Sealing, it is characterized in that: the back-up ring (1) and the black box (2) that comprise hard, at the upper and lower two ends of described back-up ring (1), the receiving groove (10) that holds described black box (2) is all set, described black box (2) is set in described receiving groove (10), and described receiving groove (10) has the sidewall of circular arc, described black box (2) part is exposed described receiving groove (10).
