A follow-up adjustable sealing distance hinge

Abstract

The invention discloses a sealing space servo adjustment hinge which comprises a first connecting piece and a second connecting piece, wherein the first connecting piece and the second connecting piece are fixedly connected into a container cabin body and are connected through a connecting block; the first connecting piece comprises an erection support fixedly connected onto a cabin door, a first shaft hole and a first rotating shaft; the first rotating shaft penetrates through the first shaft hole to be connected with one end of the connecting block and is opened and closed along with a cabin door through the erection support to drive the connecting block to rotate along with the first rotating shaft; the second connecting piece comprises an adjusting support fixedly connected onto a sealing door frame, a second shaft hole and a second rotating shaft; the second rotating shaft penetrates through the second shaft hole to be connected with the other end of the connecting block; the arrangement direction between the erection support and the adjusting support takes an L-shaped structure; and matching and positioning of the erection support and the adjusting support are realized through rotation of the connecting block. The sealing space servo adjustment hinge adjusts the sealing space through the two rotating shafts to seal the cabin body and has the characteristics of simple structure and high convenience in operation.

Description

technical field [0001] The invention relates to the technical field of sealing in pressure vessels, in particular to a hinge for adjusting the sealing distance with motion. Background technique [0002] The design of the sealing structure is an important part of the structural design of the pressure vessel, in which the door on the vessel and the door frame on the shell are connected together by hinges. The distance (seal distance) between the door sealing surface on the container and the sealing surface on the door frame determines the sealing performance of the door on the container. The cross-sectional shape of the existing sealing rubber ring is fixed, and if the sealing distance is large, the sealing effect cannot be achieved, resulting in leakage. If the sealing distance is small, it will be difficult to open and close the door on the container, and in severe cases, the door cannot be closed. [0003] At present, the hinges on the market are all in a fixed form (that...

Problems solved by technology

The cross-sectional shape of the existing sealing rubber ring is fixed, and if the sealing distance is large, the sealing effect cannot be achieved, resulting in leakage

If the sealing distance is small, it is difficult to open and close the door on the container, and in severe cases, the door cannot be closed

[0003] At present, the hinges on the market are all in a fixed form (that is, after the door, door frame and hinge are installed, the sealing distance is determined and cannot be adjusted)
