Abstract
The utility model discloses a midbody for a spring braking air chamber, which is good in sealing effect, safe and reliable and comprises a body, and a front cavity wall arranged on the body. A groove and a bulge which are connected with each other are arranged at the periphery of the contact part between the front cavity wall and a membrane. The midbody is suitable for the spring braking air chamber.
Description
Technical field
The utility model relates to a kind of spring braking air chamber, relates in particular to body in a kind of spring braking air chamber.
Background technique
The ante-chamber of body and epithelium locking position all are smooth bevels in the existing spring braking air chamber, in the using process of spring braking air chamber, under the effect of air pressure, cause epithelium back to shrink easily, to a certain degree just produce gas leak phenomenon when epithelium is retracted to, thereby influence usability.
The model utility content
The technical problems to be solved in the utility model provides body in a kind of good sealing effect, the safe and reliable spring braking air chamber.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises body, is located at the ante-chamber wall on the body, and described ante-chamber wall and epithelium contacting point periphery are provided with interconnective groove and projection.
The utility model compared with prior art has following obvious advantage and beneficial effect:
1, good sealing effect.Because the utility model, has increased the surface of contact with epithelium in ante-chamber wall and epithelium contacting point periphery employing groove and projection design, epithelium back shrinks thereby avoid in use, has improved sealability.
2, safe and reliable.Epithelium back shrinks because the utility model in ante-chamber wall and epithelium contacting point periphery employing groove and projection, can effectively be avoided in use, thereby makes safe and reliable to operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the zoomed-in view of I among Fig. 1.
Embodiment
