Abstract
The utility model relates to a novel check structure which comprises a first membrane lock base and a second membrane lock base which form a T shape, wherein a hole is formed on the first membrane lock base, in which one end of the second membrane lock base is arranged; an extension spring is arranged between the upper end surface of the first membrane lock base and the lower end surface of the second membrane lock base so as to connect the first membrane lock base and the second membrane lock base; and a seal ring is arranged on the upper end head of the first membrane lock base and is in contact with the lower end surface of the second membrane lock base. According to the novel check structure, with the seal ring on the upper end head of the first membrane lock base, the upper ends of the first and second membrane lock bases can be better sealed together after being closed.
Description
Technical field
The utility model relates to a kind of Novel check structure.
Background technique
The complicated structure of safety check in the past, and its non-return effect is also undesirable, easily reveals.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of Novel check structure is provided, solve that one-way valve non-return effect was undesirable in the past, the defective of easily revealing.
the technological scheme that its technical problem that solves the utility model adopts is: a kind of Novel check structure, comprise primary diaphragm lock and secondary diaphragm lock, described primary diaphragm lock and secondary diaphragm lock are the T font structure, be provided with perforate in described primary diaphragm lock, one termination of described secondary diaphragm lock is arranged in perforate, being provided with extension spring between the lower end surface of described primary diaphragm lock upper-end surface and secondary diaphragm lock links together primary diaphragm lock and secondary diaphragm lock, being provided with seal ring on the upper tip of described primary diaphragm lock contacts with the lower end surface of secondary diaphragm lock.
The beneficial effects of the utility model are: a kind of Novel check structure is provided, by being provided with seal ring on the upper tip of primary diaphragm lock, can better be sealed after the upper end of secondary diaphragm lock and primary diaphragm lock is closed mutually.
Description of drawings
