[0022] In the following, embodiments of the installation structure of the central air conditioner indoor unit of the present utility model will be described with reference to the accompanying drawings.

[0023] Figures 1-4 An installation structure of a central air conditioner indoor unit showing an embodiment of the present utility model includes a connection base 2 fixedly connected to the front and rear ends of both sides of the indoor unit 1: a threaded pipe 3 is arranged above the connection base 2, a lifting rod 4 is arranged at the bottom of the threaded pipe 3, the lifting rod 4 penetrates into the inner cavity of the connection base 2, a check valve assembly 5 is arranged in the inner cavity of the connection base 2, the check valve assembly 5 includes a rectangular chute 51 opened on one side of the inner wall of the connection base 2, a limit card 52 is slidably connected to the inner cavity of the rectangular chute 51, a spring 54 is welded to one side of the limit card 52, and the end of the spring 54 away from the limit card 52 is welded to the inner wall of the rectangular chute 51. Through the arrangement of the spring 54, an elastic pushing effect is exerted on the limit card 52, so that the limit card 52 can actively engage in the inner cavity of the limit card slot 53 to temporarily fix the connection base 2, thus saving the user from continuously lifting the indoor unit 1 and saving labor input. A plurality of limit card slots 53 adapted to the limit card 52 are opened on the surface of the lifting rod 4, first nuts 55 are arranged at the top and bottom of the connection base 2 and are threadedly connected to the surface of the lifting rod 4, an adjustment assembly 6 is arranged at the top end of the lifting rod 4, the adjustment assembly 6 includes a limit head 61 fixedly connected to the top of the lifting rod 4, a limit groove 62 adapted to the limit head 61 is opened at the bottom of the threaded pipe 3, a tension spring 63 is sleeved on the surface of the limit head 61, the top and bottom ends of the tension spring 63 are respectively welded to the threaded pipe 3 and the lifting rod 4, a threaded screw rod 64 is threadedly connected to the inner cavity of the threaded pipe 3, an expansion bolt 65 is fixedly connected to the top of the threaded screw rod 64, and a second nut 66 is threadedly connected to the bottom of the surface of the threaded screw rod 64, and the bottom of the second nut 66 is pressed against the top of the threaded pipe 3. Through the arrangement of the adjustment assembly 6, the cooperation of the limit head 61, the limit groove 62 and the expansion bolt 65 plays a limiting role on the lifting rod 4 to prevent the lifting rod 4 from rotating when penetrating into the inner cavity of the connection base 2, so as to ensure that the limit card 52 can accurately engage with the limit card slot 53. At the same time, under the cooperation of the threaded screw rod 64 and the expansion bolt 65, the threaded pipe 3 is lifted, and the relative rotation of the threaded pipe 3 and the threaded screw rod 64 can drive the lifting rod 4 to move up and down for adjustment.

[0024] Working principle: When the utility model is in use, the user drives the expansion bolt 65 into the wall to install and fix the threaded lead screw 64. Then the user lifts the indoor unit 1 upward so that all four connecting seats 2 are sleeved on the surface of the hoisting rod 4. At this time, under the elastic force of the tension spring 63, the limit head 61 is located at the top of the inner cavity of the limit groove 62, and the hoisting rod 4 will not rotate. After the hoisting rod 4 penetrates through the inner cavity of the connecting seat 2, the limit clamping member 52 is clamped in the inner cavity of the limit clamping groove 53 under the elastic force of the spring 54 to limit and lock the connecting seat 2. At this time, the indoor unit 1 is temporarily fixed. Then, the user releases the indoor unit 1. Under the action of gravity, the indoor unit 1 pulls the hoisting rod 4 downward, causing the limit head 61 to move to the bottom of the inner cavity of the limit groove 62, and at the same time the tension spring 63 is stretched. Then the user rotates the threaded pipe 3. During the rotation of the threaded pipe 3, due to the threaded engagement with the threaded lead screw 64, the threaded pipe 3 can be adjusted in height up and down. After the adjustment is completed, the user tightens the second nut 66 to fix the height of the threaded pipe 3. At the same time, the user tightens the first nut 55 to fix the position of the connecting seat 2.

[0025] In summary, for the installation structure of the central air-conditioning indoor unit, through the combined use of the connecting seat 2, the hoisting rod 4 and the reverse prevention assembly 5, the indoor unit 1 is fixed, so that the indoor unit 1 has a hoisting connection relationship with the threaded pipe 3. Then, through the combined use of the threaded pipe 3 and the adjustment assembly 6, the indoor unit 1 is horizontally adjusted, and the purpose of simple, fast and labor-saving installation can be achieved.
