DESCRIPTION OF THE PREFERRED EMBODIMENTS

It should be noted that, in the case of no conflicts with the scope of the invention as defined in the claims, the embodiments and features in the embodiments of the present invention can be combined mutually.
The present invention is described in detail with reference to drawings and with combination of embodiments.

1 ^st Embodiment

With reference to Figs. 1 to 3, the present embodiment provides an air conditioner base 1, the air conditioner base 1 including an upper base 2 and a lower base 3.
A first limit block 4 and at least one first hook 5 are disposed on the upper base 2, wherein the first hook 5 has two hooks. A slidable buckle 7 is disposed on the lower base 3, and a second hook 6 is disposed on the buckle 7, wherein the second hook 6 has two hooks. The first hook 5 is engaged with or separated from the second hook 6, and when the first hook 5 is engaged with the second hook 6, the upper base 2 is assembled with the lower base 3 to form a unity. When the first hook 5 is separated from the second hook 6, the upper base 2 is disassembled with the lower base 3.
A sliding direction of the buckle 7 is a front-back direction of the lower base 3, and the first limit block 4 is disposed at a rear position of the upper base 2. The first limit block 4 is used to limit a pressing distance of the buckle 7. The front-back direction here refers to the direction perpendicular to the wall surface after the air conditioner base 1 is mounted on the wall. The direction in which the air conditioner base 1 is away from the wall surface is the forward direction, and the direction in which the air conditioner base 1 is close to the wall surface is the back direction.
With reference to Fig. 3, pressing the buckle 7 from right to left gradually separates the first hook 5 from the second hook 6 until the left end of the buckle 7 abuts against the first limit block 4, then the pressing distance of the buckle 7 reaches a maximum value, at which time the buckle 7 is not retracted into the inside of the lower base 3 completely, and the pressed part of the buckle 7 also protrudes from the lower base 3. In this way, it is advantageous for the buckle 7 to be reset under the elastic force of the spring, and convenient to operate when reassembling or separating.
If there is no first limit block 4, the process of pressing the buckle 7 may easily cause the buckle 7 to move too far until retracting into the lower base 3, which causes the buckle 7 to be unable to be accurately reset, and the position of the buckle 7 must be manually adjusted, which is time consuming and laborious, and inconvenient to operate.
A second limit block 8 is disposed on the lower base 3, the second limit block 8 is opened with a through hole, and a rear end of the buckle 7 is inserted into the through hole. In this way, the through hole may guide the buckle 7.
After the upper base 2 is assembled with the lower base 3, the second limit block 8 abuts against a front side of the first limit block 4, as shown in Fig. 3, the second limit block 8 abuts against a right side of the first limit block 4. In this way, the first limit block 4 limits a backward movement of the second limit block 8, i.e., the upper base 2 limits a backward movement of the lower base 3. Preferably, the first limit block 4 is provided with an inclined plane, and the inclined plane serves as a guide for the second limit block 8, so as to facilitate the cooperation between the second limit block 8 and the first limit block 4.
The upper base 2 may further be provided with a third limit block 9, the third limit block 9 is disposed with the first limit block 4 at intervals, and a gap between the third limit block 9 and the first limit block 4 cooperates with the second limit block 8 on the lower base 3. After the upper base 2 is assembled with the lower base 3, the second limit block 8 abuts against a rear side of the third limit block 9, as shown in Fig. 3, the second limit block 8 abuts against a left side of the third limit block 9. In this way, the third limit block 9 limits a forward movement of the second limit block 8, i.e., the upper base 2 limits a forward movement of the lower base 3. Therefore, the first limit block 4 and the third limit block 9 on the upper base 2 cooperate with the second limit block 8 on the lower base 3 to achieve a limitation on the front-back movement of the upper base 2 with respect to the lower base 3.
With reference to Fig. 4, a left end and a right end of the upper base 2 may respectively be provided with a fourth limit block 10, and a left end and a right end of the lower base 3 are respectively provided with a fifth limit block 11; after the upper base 2 is assembled with the lower base 3, at least one fifth limit block 11 abuts against a left side of one fourth limit block 10, and at least one fifth limit block 11 abuts against a right side of one fourth limit block 10. In this way, a limitation on the left-right direction of the upper base 2 with respect to the lower base 3 is achieved.
In other embodiments, a limitation on the left-right direction of the upper base 2 with respect to the lower base 3 may also be achieved in other manners. For example, a left end and a right end of the upper base 2 are respectively provided with a fourth limit block 10, and a left end and a right end of the lower base 3 are respectively provided with a fifth limit block 11; after the upper base 2 is assembled with the lower base 3, at least one fifth limit block 11 abuts against a right side of one fourth limit block 10, and at least one fifth limit block 11 abuts against a left side of one fourth limit block 10. Or, a left end and a right end of the upper base 2 are respectively provided with a limit notch, and a left end and a right end of the lower base 3 are respectively provided with the fifth limit block 11; after the upper base 2 is assembled with the lower base 3, the fifth limit block 11 is located in the limit notch, and the limit notch limit a left-right movement of the fifth limit block 11, thereby similarly achieving the limitation of the upper base 2 on the lower base 3 in the left-right direction.
The air conditioner base 1 provided by the embodiment of the invention has the following advantages:

1. At least one first hook 5 is disposed on the upper base 2, and a slidable buckle 7 is disposed on the lower base 3, and at least one second hook 6 is disposed on the buckle 7, so that the first hook 5 is automatically latched with the second hook 6 after the upper base 2 is assembled with the lower base 3. Pressing the buckle 7 separates the first hook 5 from the second hook 6, so that the upper base 2 is separated from the lower base 3, which facilitates the disassembly and assembly of the upper base 2 and the lower base 3.
2. A first limit block 4 is disposed on the upper base 2, and the first limit block 4 is used to limit a pressing distance of the buckles 7 such that the buckles 7 may not be retracted into the interior of the lower base 3 and hence may not be ejected, and such that the buckles 7 may not be disengaged from the lower base 3, thereby ensuring that the buckles 7 and the second hook 6 are intact, and the upper base 2 and the lower base 3 are easy to assemble again and are safe.
3. The first limit block 4 and the third limit block 9 on the upper base 2 cooperate with the second limit block 8 on the lower base 3 to achieve a limitation on the front-back movement of the upper base 2 with respect to the lower base 3.
4. A left end and a right end of the upper base 2 are respectively provided with a fourth limit block 10, and a left end and a right end of the lower base 3 are respectively provided with a fifth limit block 11, wherein the fourth limit block 10 cooperates with the fifth limit block 11 to achieve the limitation of the upper base 2 on the lower base 3 in the left-right direction.
