Description
Technical Field
[0001] The utility model relates to the field of translation doors, and specifically to an assisted translation manhole door. Background Art
[0002] A kiln refers to a furnace used for firing ceramic wares and sculptures or for fusing enamel onto the surface of metal wares. It is generally built with bricks and stones and can be made into various sizes according to needs. It can operate using combustible gas, oil, or electricity. Electric kilns are easier to control the temperature than kilns using combustible gas and oil, but some potters and sculptors think that the temperature of electric kilns rises too fast.
[0003] The original design uses a square frame body and is connected by double-row hinges, with large friction. When the door is opened, the door body unfolds in a double-link manner to one side. The door body itself contains castable. After unfolding, the distance from the stressed hinge is too far, resulting in excessive stress on the hinge and serious deviation of the door body; the flatness of the joint surface of the original design is low and a single-ring seal is used, with poor sealing performance. It cannot solve the defects of the maintenance door used on the kiln being clumsy, difficult to open and close, with poor sealing effect, easy to cause serious external air leakage, and the locking method between the door frame and the door body being cumbersome. There are some problems in the use of the existing kiln manhole door, mainly including poor sealing performance, difficult opening and closing, and relatively large potential safety hazards. These problems not only affect the thermal efficiency of the kiln but also increase the danger coefficient of the operators.
[0004] Therefore, the technical personnel in this field provide an assisted translation manhole door to solve the problems raised in the above background art. Content of the Utility Model
