[0034] Embodiment 1

[0035] This embodiment provides a fixing structure for a low-temperature air source heat pump grille, as shown in the appendix Figures 1-6 and includes:

[0036] A panel 11, the panel 11 is provided with a plurality of through grooves 111 and first fixing holes 112. The number of through grooves 111 can be adjusted according to actual needs. In this embodiment, the through grooves 111 are distributed in a circumferential array on the panel 11.

[0037] A grille 12, the back of the grille 12 is provided with fixing posts 121 and buckles 122 that cooperate with the through grooves 111. Here, the back of the grille 12 specifically refers to the side facing the panel 11, and the front of the grille 12 is the side that can be directly seen by the operator. The fixing posts 121 are provided with second fixing holes 1211 that open towards the panel 11, and the buckles 122 are provided with fixing grooves 1221.

[0038] In the first state, the buckle 122 penetrates into the through groove 111, that is, the grille 12 moves along the axial direction towards the panel 11 until the buckle 122 passes through the panel 11. In the second state, the grille 12 is rotated. Specifically, rotating the grille 12 means that the grille 12 rotates radially. The panel 11 cooperates with the fixing groove 1221. At this time, the side walls of the fixing groove 1221 are respectively abutted against the front and back of the panel 11 to form a clamping and fixing effect. At the same time, after the rotation is in place, the first fixing hole 112 and the second fixing hole 1211 are coaxially arranged. At this time, a bolt passes through the first fixing hole 112 from the back and cooperates with the second fixing hole 1211, and the bolt will not pass through the grille 12 and extend to the front of the grille 12. The fixing posts 121 and the buckles 122 are both arranged on the back of the grille 12. After the grille 12 and the panel 11 are fixed, all the connection and fastening positions are located on the back, so that the overall front is kept flat, improving the overall aesthetics; secondly, through the cooperation of the buckle 122 and the screw, the connection and fixing effect between the grille 12 and the panel 11 is formed, improving the firmness of the fixation of the two.

[0039] Specifically, as shown in the appended Figures 5-6 figure, the aperture diameter of the first fixing hole 112 is larger than that of the second fixing hole 1211. The limitation of the aperture diameter makes it more convenient for the bolt to pass through and has better fastening performance. At the same time, the panel 11 also functions as a gasket. In addition, the aperture diameter of the first fixing hole 112 can also be equal to that of the second fixing hole 1211.

[0040] Specifically, as shown in the appended Figures 5-6 figure, a first guiding surface 1212 is provided at the opening of the second fixing hole 1211. The provision of the first guiding surface 1212 forms a guiding effect, making it more convenient to fix the bolt. Here, the first guiding surface 1212 can be an inclined surface or an arc surface.

[0041] Specifically, as shown in the appended Figures 3-4 figure, the buckle 122 is provided with a chamber 1222. The chamber 1222 opens towards the side away from the front surface of the mesh cover 12 and also opens towards the panel 11 side. The chamber 1222 and the fixing groove 1221 are independent of each other. Here, being independent specifically means that the two are not connected and do not affect each other. The provision of the chamber 1222 requires a certain amount of material for the forming of the buckle 122 during the processing. If the buckle 122 is made into a solid structure, due to excessive material, local shrinkage will occur and the surface will be deformed and uneven, affecting the overall aesthetics. Secondly, increasing the volume of the buckle 122 also increases the strength of the buckle 122.

[0042] Specifically, as shown in the appended Figures 3-4 figure, a second guiding surface 1223 is provided at the opening of the fixing groove 1221. The second guiding surface 1223 forms a guiding effect, enabling the buckle 122 to better cooperate with the panel 11 during the rotation process. It should be noted that the opening directions of the fixing grooves 1221 of the buckle 122 are the same, either all clockwise or all counterclockwise.

[0043] Specifically, the length of the buckle 122 is at least 10 mm. The limitation of the length realizes a better fitting and fixing effect between the buckle 122 and the panel 11. Here, the fixing length of the buckle 122 can be adjusted according to actual needs, but the cooperation between the buckle 122 and the through groove 111 needs to be considered to ensure that the buckle 122 can pass through the through groove 111.

[0044] Specifically, the number of the fixing columns 121 is one. The provision of one fixing column 121 reduces the number of bolts for fixing, making the assembly more convenient. That is, after the mesh cover 12 and the panel 11 are fixed in a buckle 122 - type manner, then an axial locking is formed through one bolt, thereby realizing the fixing between the mesh cover 12 and the panel 11. It should be noted that the bolt passes through the panel 11 from the back to cooperate with the mesh cover 12.

[0045] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or alterations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or alterations derived therefrom still fall within the protection scope of this utility model creation.
