[0002] The background description provided herein is intended to present the general context of this disclosure. To the extent described in this background section, the work of the currently identified inventors and aspects of the description that may not constitute prior art at the time of filing are neither explicitly nor implicitly considered to be prior art to this disclosure.

[0003] Air conditioning equipment can be a type of fresh air system. This type of equipment introduces fresh outdoor air to ensure fresh indoor air, and can also recover heat and moisture from the indoor air, achieving energy recovery and avoiding energy waste. Simultaneously, the equipment can expel stale indoor air, achieving ventilation.

[0004] However, such air conditioning equipment typically requires regular maintenance or irregular inspections. Current technology requires the access door to be opened downwards for inspection, which occupies space below the ceiling and affects room height. Furthermore, the access door is too bulky and inconvenient for maintenance.

[0005] Therefore, there is an urgent need for a space-saving and easy-to-maintain access door, as well as air conditioning equipment equipped with such an access door. Utility Model Content

The inspection door housing is arranged parallel to the housing of the equipment to be inspected, and the position of the inspection door housing corresponds to the position of the inspection port on the equipment to be inspected. The pivot and the pin are arranged at a distance from each other. The pivot is rotatably connected to the equipment to be inspected and the inspection door near the inspection port. The pin can move around the pivot on the equipment to be inspected, so that the inspection door can rotate around the pivot relative to the equipment to be inspected, thereby opening and closing the inspection port.

[0007] In one embodiment of this application, the housing of the equipment to be repaired is provided with a guide groove, and the inspection door rotates relative to the equipment to be repaired via the meshing motion between gears through the guide groove.

[0008] In one embodiment of this application, the pin is provided with a plurality of bearings, and the left inspection door moves in a guide groove through one of the bearings.

[0009] In one embodiment of the present application, the equipment to be repaired further comprises a cover plate between the access door and the shell of the equipment to be repaired and fixed to the shell, and the access door is fixed to the cover plate and the shell of the equipment to be repaired through a rotating shaft.

[0010] In one embodiment of the present application, a plurality of bearings are arranged on the rotating shaft, and the rotating shaft is rotatably connected to the access door, the cover plate and the shell of the equipment to be repaired through the fasteners and the bearings.

[0011] In one embodiment of the present application, the rotating shaft is fixedly connected to the first gear through a key, and the first gear is engaged with the second gear driven by a motor arranged on the equipment to be repaired to realize the rotation of the rotating shaft.

[0012] In one embodiment of the present application, a plurality of wear-resistant blocks are further arranged on the pin shaft, and the pin shaft is connected to the shell of the equipment to be repaired through the plurality of wear-resistant blocks.

[0013] In one embodiment of the present application, the access door comprises a left access door and a right access door which are identical in structure.

[0014] In one embodiment of the present application, the left access door and the right access door are synchronously opened and closed through gear engagement driven by a motor, and the motor is connected to the left access door through a gear.

[0015] The present application further provides an air conditioning equipment comprising the access door as described above, the access door being connected to the shell of the air conditioning equipment, and the air conditioning equipment further comprising an air filter, a heat exchanger and a fan.

[0016] The access door in the present application can move along the positioning guide groove. In the case where the air conditioning equipment is provided with a left access door and a right access door, the two access doors are synchronously opened and closed. The rotating opening of the access door does not need to disassemble the access door during equipment maintenance, and the opening of the access door does not occupy the space downward of the suspended ceiling, so that the suspended ceiling can be made thinner and the size of the access opening can be made smaller. This structure is very beneficial to the installation of the equipment in the early stage and the maintenance of the product in the use process.
