Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning boxes, and in particular relates to an air-conditioning door lock anti-air leakage structure. 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 door handle at one end of the rotating shaft can rotate the locking arm to lock or release the maintenance door. In the prior art, the locking arm is connected to the other end of the rotating shaft through a cover. The cover covers the rotating shaft mounting hole on the inner surface of the maintenance door and has a sleeve extending into the rotating shaft mounting hole. 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 maintenance door, and due to the processing accuracy, there will be a gap between the sleeve and the rotating shaft mounting hole, 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. Utility Model Content

[0004] Based on this, in order to solve the above technical problems, an air-conditioning door lock anti-air leakage structure is provided.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An air leakage prevention structure for an air conditioner door lock, comprising a cover for covering a shaft mounting hole on the air conditioner door panel on the inner surface of the air conditioner door panel, the cover being fixed to the front end of the shaft arranged in the mounting hole, the cover forming a concentric sleeve located radially outside the shaft from its interior, and characterized in that it also comprises a first sealing gasket for sealing a gap between the mounting hole and the sleeve, the sealing gasket being located between the cover and the inner surface of the air conditioner door panel and being passed through by the sleeve.

[0007] The air-conditioning door lock anti-air leakage structure provided by the utility model can prevent the cold air leaking in from between the cover opening end face of the cover and the inner surface of the air-conditioning door plate from being transmitted to the outside of the air-conditioning door lock through the gap between the mounting hole and the sleeve to form condensed water, thereby improving the service life of the air-conditioning 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 anti-air leakage structure, including a cover 110 and a first sealing gasket 120.

[0012] The cover 110 is made of PVC and has a concentric axial through hole 111 thereon. The outer peripheral surface of the cover 110 forms a radial locking arm (not shown in the figure).

[0013] like Figure 1 and Figure 2 As shown, the cover 110 has a plurality of radial ribs 113 therein to form an axial sleeve 112 , the sleeve 112 is concentric with the cover 110 and extends axially to the shaft mounting hole 31 on the air-conditioning door panel 3 .

[0014] A rotating shaft 2 is arranged in the rotating shaft mounting hole 31, and the rear end of the rotating shaft 2 is connected to the door handle 32 on the outside of the air-conditioning door panel 3. The front end of the rotating shaft 2 is a threaded section 21, and the threaded section 21 passes through the top surface of the cover 110 through the sleeve 112 and the axial through hole 111 in turn, and is fixed to the cover 110 by the nut 22, so that the cover 110 axially covers the rotating shaft mounting hole 31 on the inner surface of the air-conditioning door panel 3.

[0015] Operating the door handle 32 can rotate the rotating shaft 2, thereby driving the locking arm to rotate on the inner side of the air-conditioning door panel 3, thereby achieving locking and releasing of the door.

[0016] In order to prevent cold air from leaking into the axial through hole 111 from between the nut 22 and the cover 110, a metal gasket 23 is sleeved on the threaded section 21 and located between the nut 22 and the cover 110. The front side opening of the axial through hole 111 forms a first step adapted to the metal gasket 23, and the axial through hole 111 is blocked by the metal gasket 23.

[0017] The threaded section 21 is also provided with a second sealing gasket 24, which is a rubber sealing gasket, and is located between the metal gasket 23 and the cover 110. The second sealing gasket 24 is tightly matched with the threaded section 21, and cold air cannot pass between the two. Figure 1 As shown, the cold air leaking from between the threaded section 21 and the fixing nut 22 and the metal gasket 23 can be blocked to prevent it from entering the through hole 111. Accordingly, the front side opening of the axial through hole 111 also forms a second step adapted to the second sealing gasket 24.

[0018] The first sealing gasket 120 is a rubber sealing gasket, which is located between the cover 110 and the inner surface of the air-conditioning door panel 3 and is sleeved on the sleeve 112 to seal the gap between the installation hole 31 and the sleeve 112 .

[0019] In this embodiment, the inner wall of the cover opening of the cover 110 forms a fixed step, and the first sealing gasket 120 is arranged on the fixed step (such as being able to be fixed by bonding). The outer diameter of the first sealing gasket 120 is equal to the inner diameter of the cover opening, and the outer surface of the first sealing gasket 120 is flush with the end face of the cover opening.

[0020] like Figure 1 As shown, the cold air leaking in from between the cover end face of the cover 110 and the inner surface of the air-conditioning door panel 3 will be blocked by the first sealing gasket 120, preventing it from being transmitted to the outside of the air-conditioning door lock through the gap between the mounting hole 31 and the sleeve 112 to form condensed water.

[0021] From the above, it can be seen that the air-conditioning door lock anti-leakage structure provided in the embodiment of the present application can prevent the cold air leaking in from between the cover opening end face of the cover and the inner surface of the air-conditioning door panel from being transmitted to the outside of the air-conditioning door lock through the gap between the mounting hole and the sleeve, thereby forming condensed water and improving the service life of the air-conditioning door lock by setting a first sealing gasket.

[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.
