Description

Technical Field

[0001] The utility model relates to the technical field of central air conditioners, in particular to an air outlet buckle locking device which is beneficial to maintaining the cleanliness of a central air conditioner. Background Art

[0002] The central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. This system is different from traditional refrigerant air conditioners (such as single units, VRV) that centrally process air to achieve comfort requirements. The principle of liquid vaporization refrigeration is used to provide the required cooling capacity for the air conditioning system to offset the heat load of the indoor environment; the heating system provides the required heat for the air conditioning system to offset the cold and warm loads of the indoor environment.

[0003] Existing central air conditioners generally install grilles at the air outlet to prevent dust and ash, and can play the role of diversion and filtering to prevent dust and other impurities from entering the system, so as to keep the central air conditioner outlet more beautiful and clean. The grille is generally installed at the air outlet with multiple bolts, and the installation procedure is relatively cumbersome. After being used for a long time, a certain amount of dust will adhere to the grille, which is not convenient to disassemble and clean. Therefore, we have launched a new air outlet locking device that is conducive to maintaining the cleanliness of the central air conditioner. Utility Model Content

[0010] Preferably, the two movable rods are respectively interlaced and connected with the two connecting tubes.

[0011] Preferably, the two buckle blocks are buckled and connected to the two buckle strips via two buckle grooves respectively.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By aligning the four positioning blocks under the grille plate with the four positioning slots above the air outlet frame, and then respectively snapping the four positioning blocks into the four positioning slots, the sealing ring under the grille plate fits tightly with the air outlet frame, so that the grille plate can be quickly initially positioned and installed with the air outlet frame, and the sealing ring can improve the connection and sealing between the air outlet frame and the grille plate;

[0014] 2. After the grille plate is initially positioned and installed, fold the buckle block upwards and pull the buckle block upwards to stretch the spring inside the connecting tube. Then pass the buckle groove on the buckle block through the buckle bar and release the buckle block. The buckle block is buckled and connected with the buckle bar under the elastic force of the spring. This allows the grille plate to be further locked and fixed to prevent the grille plate from loosening.
