[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figures 1 to 4 A temperature control device for energy saving of a central air conditioner shown in the figure comprises a temperature control device body 1 and an installation box 2, a mounting plate 3 is installed inside the installation box 2, a fixing frame 4 is fixed on the back of the mounting plate 3, the back of the temperature control device body 1 extends to the inner cavity of the fixing frame 4, a screw hole 5 is provided on the back of the fixing frame 4, a screw rod 6 is fixed on the back of the temperature control device body 1, one end of the screw rod 6 away from the temperature control device body 1 passes through the inner cavity of the screw hole 5 and is threadedly connected with the screw hole 5, the back of the fixing frame 4 is arranged in an elastic arc shape, and a storage groove 7 matching the mounting plate 3 is provided on the back of the temperature control device body 1.

[0022] By installing the mounting plate 3 and the fixing frame 4 inside the mounting box 2, the screw 6 on the back of the temperature control device body 1 is threadedly connected with the screw hole 5 on the back of the fixing frame 4, so that the temperature control device body 1 fits the mounting box 2. At the same time, the back of the fixing frame 4 is designed with an elastic structure. Before the temperature control device body 1 contacts the mounting plate 3, the position of the temperature control device body 1 is adjusted, and it is pressed backward to make the temperature control device body 1 and the mounting plate 3 snap together. Then, the plug plate 12 on the buckle plate 102 is snapped together with the limit groove 14 on the mounting plate 3 to prevent the temperature control device body 101 from shaking. The disassembly and assembly of the temperature control device body 101 is extremely convenient and quick, and the risk of safety accidents is extremely low, which solves the problem of complicated disassembly and assembly of the traditional temperature control device body 1.

[0023] Countersunk holes are provided on both sides of the front side of the mounting plate 3, and mounting screws 8 are movably provided in the inner cavity of the countersunk holes. One end of the mounting screw 8 passes through the inner cavity of the mounting box 2 and is threadedly connected to the screw mounting column in the mounting box 2. Multiple sets of gaskets 9 are sleeved on the outer side of the mounting screw 8. The gasket 9 is located between the mounting box 2 and the mounting plate 3. The setting of the mounting screw 8 makes it convenient to install the mounting plate 3 in the mounting box 2. At the same time, the setting of the gasket 9 makes it convenient to adjust the position of the mounting plate 3 to avoid the mounting box 2 being embedded too deeply in the wall, resulting in the inability of the temperature control device body 1 to be connected with the mounting plate 3.

[0024] A fixing plate 10 is fixed to the inner cavity of the fixing frame 4, and a through hole for the screw 6 to pass through is opened at the center of the fixing plate 10. A support spring 11 is fixed to the side of the fixing plate 10 away from the temperature control device body 1, and the other end of the support spring 11 is fixed to the inner cavity of the fixing frame 4. Through the arrangement of the fixing plate 10 and the support spring 11, the elastic arc structure on the back of the fixing frame 4 is supported by the support spring 11, thereby limiting the temperature control device body 1 from being moved out of the installation box 2 again, causing the temperature control device body 1 to shake.

[0025] The temperature control device body 1 includes a temperature control device body 101 and a buckle plate 102. The buckle plate 102 is snapped onto the outer side of the temperature control device body 101. A plurality of plug-in plates 12 are fixed to the back of the buckle plate 102. A slot 13 corresponding to the plug-in plate 12 is provided on the outer side of the temperature control device body 101. The setting of the buckle plate 102 facilitates the cleanliness of the outer side of the temperature control device body 1. At the same time, the plug-in plate 12 and the slot 13 can ensure the stability of the buckle plate 102.

[0026] A chamfer is provided on one side of the outer side of the mounting plate 3 close to the temperature control device body 1, and limit grooves 14 aligned with the slots 13 are provided around the mounting plate 3. By providing a chamfer on the outer side of the mounting plate 3, after the temperature control device body 101 contacts the mounting plate 3, if the position of the temperature control device body 101 does not reach the standard position, the chamfer can be set to continue to make the temperature control device body 101 rotate in contact with the mounting plate 3, thereby driving the screw 6 to rotate in the screw hole 5.

[0027] A groove 15 is provided on the side of the fixing plate 10 facing the fixing frame 4. Both ends of the support spring 11 are located in the inner cavity of the groove 15. The setting of the groove 15 facilitates the positioning of the support spring 11 to prevent the support spring 11 from displacement.

[0028] The size of the mounting plate 3 is larger than the size of the mounting wire box 2, and the size of the mounting plate 3 is smaller than the size of the temperature control device body 1. By limiting the sizes of the mounting plate 3, the mounting wire box 2 and the temperature control device body 1, it is ensured that the mounting plate 3 supports the temperature control device body 1, and at the same time, the temperature control device body 1 can cover the mounting plate 3 to ensure the beautiful appearance.

[0029] When in use, place the mounting plate 3 at the front end of the mounting wire box 2, press the elastic arc structure on the back of the fixing frame 4 into the fixing frame 4, insert the mounting screws 8 into the countersunk holes and put on the gaskets 9, use the mounting screws 8 to mount the mounting plate 3 on the front end of the mounting wire box 2, and ensure that the mounting plate 3 is flush with the wall. At this time, the fixing frame 4 is placed inside the mounting wire box 2, and then the buckle plate 102 is separated from the temperature control device body 101, and the temperature control device body 101 is first inserted into the fixing frame 4, the screw 6 passes through the fixing plate 10 and is threadedly connected to the screw hole 5 on the back of the fixing frame 4. As the temperature control device body 101 rotates, the temperature control device body 101 is close to the mounting plate 3, and at the most After that, the gap between the temperature control device body 101 and the mounting plate 3 is extremely small and the position of the temperature control device body 101 is correct. At this time, the temperature control device body 101 is pressed backward, and the elastic arc structure on the back of the fixed frame 4 is driven to move to the outside of the fixed frame 4 through the screw 6. At the same time, the screw 6 and the temperature control device body 101 are further pulled backward. At this time, the mounting plate 3 is clamped with the temperature control device body 101, and then the buckle plate 102 is put on the outside of the temperature control device body 101, and the buckle plate 102 is installed using the plug plate 12 and the slot 13. At the same time, the plug plate 12 is clamped with the limit groove 14 on the outside of the mounting plate 3 to prevent the temperature control device body 101 and the mounting plate 3 from rotating again.
