Technical Field

The invention relates to the technical field of vacuum, in particular to a rotatable caliper for a vacuum container, which is particularly suitable for sealing between a seal head and a container flange of the vacuum container.

Background

When a vacuum container is used, the vacuum degree needs to be maintained, the sealing between the sealing head of the vacuum container and the container flange is ensured, and particularly, the container needs to be sealed in a large size or a large moment. The caliper used at present wholly rotates around a round hole in a flange at one end of the caliper to open the caliper, so that the caliper does not interfere with a vacuum container seal head in space when moving. When a large-size and large-diameter container end socket is met or large torque is needed for sealing, the calipers can be very heavy so as to realize high bending strength, and the calipers need large physical force for manual overturning and have certain potential safety hazards. If the calipers are pushed by the air cylinders, enough sealing force cannot be provided, and the calipers cannot be suitable for sealing occasions of some special vacuum containers.
