[0023] In order to make the purpose and advantages of the present utility model more clear, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.

[0024] As Figures 1 - 3 shown, an evaporator fixing structure includes a housing 1, an evaporator main body 2 is arranged inside the housing 1, a buckle assembly capable of fixing the evaporator main body 2 is arranged at the inner top of the housing 1, and a fixing assembly for limiting the buckle assembly is arranged inside the housing 1;

[0025] The buckle assembly includes a plurality of connecting plates 3 rotatably installed at the inner top of the housing 1 and inside the evaporator main body 2. A latch block 4 is fixed to the bottom of the connecting plate 3. The latch block 4 is stuck to the bottom of the evaporator main body 2. An inclined plate is arranged on one side of the latch block 4. The arrangement of the inclined plate facilitates the evaporator main body 2 to be directly sleeved on the plurality of latch blocks 4, facilitating the quick installation and fixation of the evaporator main body 2. A plurality of mounting plates 5 are fixed to the inner top of the housing 1. A chute 6 is opened at the bottom of the mounting plate 5. A slide block 7 is installed in the chute 6 in a damped sliding manner. A first spring 8 fixed to the inner side of the chute 6 is fixed to one side of the slide block 7. The damped sliding of the slide block 7 in the chute 6 and the cooperation with the first spring 8 can buffer the installed evaporator main body 2, avoiding damage to the evaporator main body 2 due to vibration during air conditioner use. A first connecting rod 9 rotatably connected to the connecting plate 3 is rotatably installed at the bottom of the slide block 7. Positioning guide bars 14 are fixed to both sides of the latch block 4 on the inner sides of the four sides of the evaporator main body 2. When installing the evaporator main body 2, the latch block 4 can be positioned and limited, improving the installation efficiency.

[0026] According to the above structure, when installing the evaporator main body 2, align the clamping block 4 between the two positioning guide bars 14, and then directly push the evaporator main body 2 upwards until the clamping block 4 moves along between the two positioning guide bars 14 to the lower part of the evaporator main body 2. At this time, through the elastic force of the first spring 8, the slider 7 is pushed to move. The slider 7 drives the connecting plate 3 to rotate through the first connecting rod 9, so that the connecting plate 3 drives the clamping block 4 to be stuck under the evaporator main body 2, realizing the installation and fixation of the evaporator main body 2 and the housing 1. One person can quickly install it, avoiding the trouble of bolting while holding it up, and improving the installation efficiency.

[0027] As Figures 2 - 3 shown, the fixing assembly includes a guide rod 10 fixed to the inner top of the middle part of the housing 1. A sleeve 11 is slidably installed on the outer wall of the guide rod 10. A second connecting rod 12 rotatably installed with the connecting plate 3 is rotatably installed on the outer surface of the sleeve 11. A large head bolt 13 is screwed through the outer wall of the sleeve 11, and one end of the large head bolt 13 abuts against the outer wall of the guide rod 10.

[0028] According to the above structure, by tightening the large head bolt 13, the connecting plate 3 can be locked to prevent the connecting plate 3 from rotating, improving the stability of the fixation of the evaporator main body 2. When loosening the large head bolt 13, the sleeve 11 can slide freely on the guide rod 10, canceling the limit on the connecting plate 3. At the same time, it is also convenient to control the rotation of multiple connecting plates 3 at the same time, and make the clamping block 4 separate from the evaporator main body 2, facilitating the quick disassembly of the evaporator main body 2 and increasing the practicality of the equipment.

[0029] As Figure 2 and Figure 4 shown, a plugging groove 16 is formed at the top of the clamping block 4. A buffer block 17 is installed in the plugging groove 16 in a damped sliding manner. A second spring 18 fixed to the inner wall of the plugging groove 16 is fixed to the bottom of the buffer block 17, which can further damp and buffer the installation of the evaporator main body 2, effectively protecting the evaporator main body 2 from being damaged by collision, improving the service life and the stability of use of the equipment. A first washer 15 in contact with the evaporator main body 2 is fixed to the inner top of the housing 1, avoiding the hard contact between the evaporator main body 2 and the inner wall of the housing 1 and facilitating the protection of the evaporator main body 2.

[0030] As Figure 1 shown, an air conditioner includes an evaporator fixing structure, and a bottom cover 19 is arranged at the bottom of the housing 1.

[0031] The working principle of the present utility model is as follows: When installing the evaporator main body 2, align the block 4 between the two positioning guide bars 14, and then directly push the evaporator main body 2 upwards until the block 4 moves along between the two positioning guide bars 14 to the lower part of the evaporator main body 2. At this time, the elastic force of the first spring 8 pushes the slider 7 to move. The slider 7 drives the connecting plate 3 to rotate through the first connecting rod 9, so that the connecting plate 3 drives the block 4 to be stuck under the evaporator main body 2, realizing the installation and fixation of the evaporator main body 2 and the housing 1. Finally, by tightening the big head bolt 13, the connecting plate 3 is locked to prevent the rotation of the connecting plate 3, further improving the stability of the installation and fixation of the evaporator main body 2; When disassembling the evaporator main body 2, first loosen the big head bolt 13, and then push the sleeve 11. The sleeve 11 drives the connecting plate 3 to rotate through the second connecting rod 12, and then drives the block 4 to separate from the bottom of the evaporator main body 2, and then the evaporator main body 2 can be disassembled.

[0032] The above is only the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model. The structures, devices and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in this field.
