Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning boxes, and in particular relates to a sealing structure for an air-conditioning door lock. Background Art

[0002] The air conditioner cabinet is a key component in the air conditioning system, which plays a role in protecting internal components, heat insulation and thermal insulation, and structural support. The air conditioner cabinet is usually equipped with an access door to facilitate technicians to conduct daily inspections, maintenance, repairs or replacement of components in the air conditioning system.

[0003] The door lock of the air-conditioning maintenance door has a rotating shaft and a locking arm that rotates with the rotating shaft. The rotating shaft is arranged in the rotating shaft mounting hole of the maintenance door. The fixed head at one end of the locking arm has a through hole corresponding to the rotating shaft. The front end of the rotating shaft is a threaded section. The threaded section passes through the through hole from back to front and is fixed to the fixed head by a fixing nut. A metal gasket is arranged between the fixing nut and the fixing head to prevent cold air from leaking into the through hole from between the fixing nut and the fixing head. However, cold air may also leak into the through hole from between the threaded section, the fixing nut and the metal gasket, and be transmitted to the outside of the air-conditioning door lock to form condensed water, which affects the life of the door lock.

[0010] The following will illustrate the implementation methods of the utility model in conjunction with the drawings in the specification. It should be noted that the implementation methods involved in this specification are not exhaustive and do not represent the only implementation methods of the utility model. The following corresponding embodiments are only for the purpose of clearly illustrating the utility model content of the utility model patent, and are not intended to limit its implementation methods. For ordinary technicians in this field, different forms of changes and modifications can be made on the basis of the description of this embodiment. All obvious changes or modifications that belong to the technical concept and utility model content of the utility model are also within the scope of protection of the utility model.

[0011] like Figure 1 As shown, an embodiment of the present application provides an air-conditioning door lock sealing structure, including a metal gasket 110 and a first sealing gasket 120 .

[0012] A rotating shaft 3 is arranged in the rotating shaft mounting hole 21 on the air-conditioning door panel 2 .

[0013] One end of the locking arm (not shown in the figure) has a fixing head 4 , which is made of PVC and is designed as a cover structure. The cover has a through hole 41 corresponding to the rotating shaft 3 .

[0014] like Figure 1 and Figure 2 As shown, the cover is formed with a plurality of radial ribs 43 therein to form an axial sleeve 42 , the sleeve 42 is concentric with the cover and extends axially into the shaft mounting hole 21 .

[0015] The rear end of the rotating shaft 3 is connected to the door handle 22 on the outside of the air-conditioning door panel 2, and the front end of the rotating shaft 3 is a threaded section 31. The threaded section 31 passes through the top surface of the cover through the sleeve 42 and the through hole 41 from back to front, and is fixed to the cover by a fixing nut 32, so that the cover axially covers the rotating shaft mounting hole 21 on the inner surface of the air-conditioning door panel 2.

[0016] Operating the door handle 22 can rotate the rotating shaft 3, thereby driving the locking arm to rotate on the inner side of the air-conditioning door panel 2 through the fixed head 4, thereby realizing the locking and releasing of the door.

[0017] Among them, the cover can play a certain role in sealing and preventing air leakage. However, cold air is still likely to leak in from between the cover and the inner surface of the air-conditioning door panel 2, and due to the processing accuracy, there will be a gap between the sleeve 42 and the shaft mounting hole 21, so that the leaked cold air is transmitted to the outside of the air-conditioning door lock through the gap to form condensed water, which affects the life of the door lock. In order to overcome this problem, a second sealing gasket 130 is provided between the cover and the inner surface of the air-conditioning door panel 2. The second sealing gasket 130 is a rubber sealing gasket, which is sleeved on the sleeve 42 to seal the gap between the mounting hole 21 and the sleeve 42.

[0018] In this embodiment, a fixed step is formed on the inner wall of the cover opening, and the second sealing gasket 130 is arranged on the fixed step. The outer diameter of the second sealing gasket 130 is equal to the inner diameter of the cover opening, and the side of the second sealing gasket 130 facing the air-conditioning door panel is flush with the end face of the cover opening.

[0019] like Figure 1 As shown, the cold air leaking in from between the cover end surface of the cover and the inner surface of the air-conditioning door panel 2 will be blocked by the second sealing gasket 130, preventing it from being transmitted to the outside of the air-conditioning door lock through the gap between the mounting hole 21 and the sleeve 42 to form condensed water.

[0020] The metal gasket 110 and the first sealing gasket 120 are sleeved on the threaded section 31 and located between the nut 32 and the cover. The metal gasket 110 is located on the front side of the first sealing gasket 120. The front side opening of the through hole 41 forms a first step and a second step respectively adapted to the metal gasket 110 and the first sealing gasket 120. Under the blocking effect of the metal gasket 110, cold air cannot leak into the through hole 41 from between the fixing nut 32 and the cover. At the same time, the first sealing gasket 120 adopts a rubber sealing gasket, which is tightly matched with the threaded section 31, and cold air cannot pass between the two. Figure 1 As shown, the cold air leaking from between the threaded section 31 and the fixing nut 32 and the metal gasket 110 can be blocked to prevent the cold air from entering the through hole 41 .

[0021] From the above, it can be seen that the air-conditioning door lock sealing structure provided in the embodiment of the present application, by setting a first sealing gasket, can prevent cold air from leaking into the through hole between the threaded section and the fixing nut and the metal gasket, and then being transmitted to the outside of the air-conditioning door lock to form condensed water, thereby improving the service life of the air-conditioning door lock.

[0022] Obviously, those skilled in the art should realize that the above embodiments are only used to illustrate the present invention, and are not used to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
