Description

Technical Field

[0001] This utility model relates to the field of industrial and laboratory equipment technology, and more specifically, it relates to a folding door for equipment. Background Technology

[0002] With the acceleration of industrial automation and the increasing frequency of laboratory research activities, the safety protection needs of industrial and laboratory equipment are becoming increasingly critical. To prevent accidental injuries caused by personnel accidentally touching moving parts or foreign objects being thrown out of the equipment, sturdy protective doors must be installed on both sides or one side of the equipment. The size of the door needs to take into account both the height of the equipment and the opening requirements. However, in actual workshop environments, limited space resources and the requirements for personnel passage and equipment layout create a sharp contradiction: if the door size is too large, it will easily encroach on the passageway when opened and interfere with the equipment layout; if the door size is too small, it will not meet the space requirements for personnel to perform necessary operations such as debugging and maintenance of the equipment.

[0003] Traditional sliding door designs, while offering a large opening space through vertical movement and avoiding obstruction of horizontal passageways, have stringent requirements for workshop ceiling height. This makes them unsuitable for low-ceilinged factories or space-constrained laboratories, significantly limiting their application. Meanwhile, other common sliding and hinged door structures also suffer from low space utilization and poor sealing. Therefore, developing a door structure for equipment that can adapt to diverse spatial conditions while ensuring operational convenience and safety has become a pressing technical challenge.

[0033] When the folding door is opened: the operator uses the hidden latch handle 21 on the lower door assembly 2 to separate the lower door assembly 2 from the side door frame 5 which is attracted by the second suction assembly 8, and flips the lower door assembly 2 upward until the lower door assembly 2 and the upper door assembly 1 are attracted together as a whole by the first suction assembly 7. Then, the operator uses the upper door handle 11 to flip the upper door assembly 1 and the lower door assembly 2 upward as a whole until the telescopic support assembly 3 extends its telescopic end fully, supporting the upper door assembly 1 and the lower door assembly 2 as a whole, and the folding door opens.

[0034] When the folding door is closed: the staff closes the upper door assembly 1 and the lower door assembly 2 together by using the upper door handle 11 and the first suction assembly 7. At the same time, the telescopic support assembly 3 retracts its telescopic end. Then, the staff pulls down the lower door assembly 2 using the concealed latch handle 21 to separate the lower door assembly 2 from the upper door assembly 1. This causes the lower door assembly 2 to flip downward and be suctioned to the side door frame 5 by the second suction assembly 8, thus closing the folding door.
