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.
