Description

Technical Field

[0001] The utility model relates to a simple air-conditioning inspection door observation mirror component and an air-conditioning inspection door comprising the same, belonging to the technical field of inspection door observation mirrors. Background Art

[0002] The air conditioner fan is a new type of energy-saving, high-efficiency, variable speed, low-noise centrifugal fan. This type of fan has a compact structure, easy installation, small size, large air volume, high pressure, and low vibration. It is equipped with a three-phase voltage regulator or frequency converter and can implement stepless speed regulation. It is particularly suitable for ventilation places with strict noise requirements and a large range of air volume changes. It is an ideal supporting product for air conditioning, purification and other industries. The air conditioner fan box is used to install the air conditioner fan. It is usually necessary to set an inspection door on the air conditioner box so that maintenance personnel can directly open the inspection door to maintain and repair the air conditioner.

[0003] In order to facilitate observation, an observation mirror is usually set on the air-conditioning maintenance door. For example, the patent with application number 202222853001.3 discloses an air-conditioning maintenance door with a lock and an observation window for an outdoor unit, including a door frame, a door panel hingedly connected to the inner side of the door frame, the door panel is provided with a viewing window, the door panel is provided with a handle, and the handle is provided with a push-to-unlock structure, which is used to open the door panel. This patent pushes the handle's rotating shaft to slide toward the step shaft, and when it is rotated to a fixed angle, the limit block can be inserted into the limit card slot. At this time, further rotating the handle can drive the step shaft to rotate, and the step shaft drives the locking rod to exit the socket, and the lock can be unlocked. In this way, the inconvenience of carrying keys is overcome, basic protection can be provided, and it is convenient to use. However, this patent adopts a traditional observation window and does not make any improvements to the observation window. For another example, the patent with application number 202020576940.6 discloses an industrial air-conditioning maintenance door, including a door frame, a door panel and a door handle, the door frame and the door panel are connected by heavy-duty hinges, the door frame includes a first door frame on which the heavy-duty hinges are installed and a second door frame on which a sealing strip is installed, the door panel includes an outer door panel and an inner door panel, the inner door panel is embedded in the outer door panel, and a circle of outer grooves formed at the joint is provided with a sealing strip, and an observation window assembly is provided in the middle of the door panel, the observation window assembly includes tempered glass, glass inlays, glass trims, wall panels and steel rings, the steel rings are provided on the upper part of the door panel, the glass inlays and the wall panels are embedded in the inlay grooves of the glass trims, and the tempered glass is embedded between the glass trims. The above-mentioned device solves the technical problems that the air-conditioning maintenance door in the prior art has poor sealing, causing leakage of cold (hot) air, and increasing the load of the unit, improves the sealing performance of the maintenance door, and reduces the load of the air-conditioning unit. This patent also uses a traditional observation window and does not make improvements to the observation window. Traditional observation mirrors have 6 threaded holes around the outer frame and the inner frame. During installation, the 6 threaded holes on the outer frame need to be aligned with the 6 threaded holes on the inner frame, which makes installation difficult and disassembly inconvenient. It is very easy to cause damage and scrapping of the outer frame and the inner frame during disassembly and assembly. In addition, the outer frame and the inner frame are just close together, so it is necessary to install sealing strips not only between the air conditioning maintenance door and the outer frame and the inner frame, but also between the outer frame and the inner frame. At the same time, the thickness control precision of the door panel of the air conditioning maintenance door is high. Once the foaming thickness of the door panel deviates, installation will be difficult. If the door panel is too thick, it will affect the sealing of the joint between the outer and inner frames. In addition, the length of the mounting bolts is limited, and the installation stability will deteriorate. If the door panel is too thin, it is difficult to ensure the sealing between the outer and inner frames and the door panel of the air conditioning maintenance door. Utility Model Content
