Abstract
The invention discloses a safety sealed membrane type spring cylinder, which mainly comprises a middle body and a back cover. The upper end of the middle body is provided with an opening brim, the lower end of the back cover is provided with a cover brim matched with the opening brim, a membrane is arranged in a cavity formed between the opening brim and the cover brim, the outer brim of the opening brim is downwards extended to form an edge, a locking ring is arranged in a groove ring formed by the back cover, the cover brim and the edge, and the edge and the locking ring are fixedly connected through a locking pin. The spring cylinder has the following advantages: through saving a collar clamp, a collar clamp bolt and a nut, and slightly changing the structure of the middle body, the safety sealed membrane type spring cylinder can replace the special collar clamp bolt, the nut and the collar clamp only by using the locking ring and the locking pin, and achieve connection of the middle body and the back cover. Simultaneously, the spring cylinder has constant assembly interference magnitude of the membrane, improves the working condition of the membrane, prolongs the service life of the membrane, and has the characteristics of novel structure, beautiful appearance, and safe and reliable work.
Description
Technical field
The present invention relates to diaphragm type spring cylinder, more specifically say, it relates to a kind of security-sealing diaphragm type spring cylinder.
Background technique
The middle body of the diaphragm type spring cylinder of prior art claims again that with bonnet being connected of spring chamber is the mode that adds clip bolt, nut with clip, and its deficiency is: 1. two of clip hangers increase the largest contours of entire product, and interference is arranged when car load assembles; 2. the assembling magnitude of interference of diaphragm is except depending on the clamping force of clip fully, and the friction when also being clamped, the foozle of each mating parts influence; 3. clip hanger opening easily leaks.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, provide a kind of rational in infrastructure, the assembling magnitude of interference is constant, is difficult for leaking safe and reliable security-sealing diaphragm type spring cylinder.
The objective of the invention is to be achieved through the following technical solutions.This security-sealing diaphragm type spring cylinder, body and bonnet in mainly comprising, the upper end of body is provided with peristoma in described, the lower end of bonnet is provided with the lid eaves that matches with peristoma, be provided with diaphragm in the cavity that between peristoma and lid eaves, forms, the outer rim of peristoma extends to form rim downwards, is provided with locking ring in the groove circle that bonnet, lid eaves and rim form, and rim is fixedlyed connected by check pin with locking ring.
The outer rim of described peristoma extends to form rim vertically downward.
Described peristoma is provided with antiskid groove, and antiskid groove matches with diaphragm.
Described lid eaves and peristoma are provided with the projection that is used to clamp diaphragm, the horn-like cavity that forms between peristoma and lid eaves.
The effect that the present invention is useful: by omitting clip, clip bolt, nut, the structure of body in changing slightly, security-sealing diaphragm type spring cylinder of the present invention only can replace clamp special bolt, nut and clip with a locking ring and a check pin, and body and bonnet is connected in the realization.Make the assembling magnitude of interference of diaphragm constant simultaneously, improved the diaphragm operating conditions, prolong its working life, have novel structure, specious, safe and reliable characteristics.

Embodiment
Below in conjunction with drawings and Examples the present invention is described further.Though the present invention will be described in conjunction with preferred embodiment, should know, do not represent to limit the invention among the described embodiment.On the contrary, the present invention will be contained alternative, modified model and the equivalent in the scope of the present invention that can be included in attached claims qualification.
Referring to Fig. 1-3, this security-sealing diaphragm type spring cylinder, body 2 and bonnet 1 in mainly comprising, the upper end of body 2 is provided with peristoma 2-1 in described, the lower end of bonnet 1 is provided with the lid eaves 1-1 that matches with peristoma 2-1, be provided with diaphragm 5 in the cavity that between peristoma 2-1 and lid eaves 1-1, forms, the outer rim of peristoma 2-1 extends to form rim 2-2 vertically downward, in the groove circle that bonnet 4, lid eaves 1-1 and rim 2-2 form, be provided with locking ring 3, locking ring 3 is structure ringwise, have the through hole that check pin 6 is installed above, rim 2-2 is fixedlyed connected by check pin 6 with locking ring 3.Described peristoma 2-1 is provided with antiskid groove 4, and antiskid groove 4 matches with the outstanding of diaphragm 5, makes connection tightr.Described lid eaves 1-1 and peristoma 2-1 are provided with the projection 7 that is used to clamp diaphragm 3, the horn-like cavity that forms between peristoma 2-1 and lid eaves 1-1, the structure of antiskid groove 4 and horn-like cavity all makes diaphragm 5 to link together closely with middle body 2 and bonnet 1.
Security-sealing diaphragm type spring cylinder of the present invention has omitted clip, clip bolt, nut, and the structure of body in changing slightly only can replace being connected of body 2 and bonnet 4 in clip, clip bolt, the nut realization with a locking ring 3 and a check pin 6.
