Description

Technical Field

[0001] The utility model relates to the technical field of hanging rail sliding doors, in particular to a device for reducing tension by sinking and tilting a clean door. Background Art

[0002] In order to solve the sealing problem of traditional hanging rail sliding doors, the hanging rail is processed by utilizing the contact between the hanging rail and the hanging wheel so that the door leaf will sink 5-7mm when closing, and move inward 3-5mm. When the door leaf sinks, the lower sill rubber strip contacts the ground and the door leaf moves inward, and the inner rubber strip and the auxiliary frame rubber strip can be in close contact to meet the sealing requirements. This method solves the sealing problem, but because the door leaf needs to be lifted 5-7mm along the hanging rail to return to the normal sliding state when opening, the process of lifting the door leaf will generate a huge pulling force, which increases the weight requirements of the motor, synchronous belt and door leaf. The first two items can be solved, but the weight of the door leaf can only be used for ordinary airtight doors, and cannot be used for radiation-proof doors used in some overweight operating rooms because the door leaf is too heavy for the motor to pull it. Therefore, it is necessary to develop a device to reduce the tension of the clean door by sinking inward. Utility Model Content
