[0031] At the same time, the present invention also provides a bracket assembly for fixing the indoor heater. Figure 3-Figure 10The bracket 3 is an H-shaped bracket, which is made of a metal plate and is H-shaped as a whole. The four lower fixing parts are arranged at the four corners of the fixing bracket 3. It can be fixed to the fixing bracket 3 by welding or bolts. The number of the upper fixing parts 2 is the same as that of the lower fixing parts 4, which is also four. It can be fixed to the rear end of the indoor heater, that is, the back plate, by bolts. After installation, the upper fixing parts 2 correspond to the lower fixing parts 4 one by one. One of the upper fixing parts 2 and the lower fixing parts 4 is a hook and the other is a hanging slot. Their positions can be interchanged, that is, when the upper fixing part 2 is a hook, the lower fixing part is a slot, and when the upper fixing part is a hanging slot, the lower fixing part is a hook; the upper fixing part 2 can be hung on the lower fixing part 4 and can be moved back and forth. In this application, the panel direction of the indoor heater is defined as the front, the back plate direction is defined as the rear, and the hanging The end of the hook is bent 90 degrees to form a hook; a plurality of adjustment support blocks 5 are provided on the back (back plate) of the indoor heater. In this embodiment, there are also four of them, and they are respectively arranged at the four corners of the heater. A bolt 51 arranged backward is fixed on the back plate of the heater to form a screw. The adjustment support block 5 is cylindrical and is installed on the screw by thread rotation.

At the same time, the end of the hook is provided with a chamfer, which is convenient for quick alignment and insertion, thereby improving installation efficiency.

[0032] In the present application, the upper fixing member 2 and the lower fixing member 4 are formed by stamping and bending metal plates.

[0033] The following is an explanation based on different configurations of the upper fixing member 2 and the lower fixing member 4:

[0034] In the first embodiment, a lower support portion 43 is provided on the lower fixing member 4, and the top of the lower supporting portion 43 forms a first supporting surface 43a, and a first hook 42 facing upward is provided at the front end portion of the lower supporting portion 43, and the end of the first hook 42 is bent 90 degrees toward one side of the lower supporting portion 43, that is, bent 90 degrees backward to form a first hook 421; an upper supporting portion 23 is provided on the upper fixing member 2, and the bottom surface of the upper supporting portion 23 forms a second supporting surface 23a, which can contact the first supporting surface 43a on the lower supporting portion 43, thereby realizing axial support, and a first groove body 20 is provided on the upper supporting portion 23. The first groove body 20 can accommodate the first hook 42 to be axially inserted from bottom to top and can realize forward and backward movement. When the first hook moves to the end of the first groove body, that is, when the upper fixing member moves to the front limit position, the first hook 421 can hook the top (locking surface) of the upper supporting portion 23, thereby limiting its upward movement, that is, at this time, the upper fixing member cannot move upward, thereby achieving the fixation of the two.

[0035] In this embodiment, the upper fixing member serves as a hanging slot and the lower fixing member serves as a hook;

[0036] Specifically, the lower fixing member includes a first plate body 41, both ends of the first plate body 41 are bent backward to form a lower support portion 43, and a second groove body 40 is formed between the two lower support portions. In this embodiment, the second groove body is a trapezoid, preferably, an isosceles trapezoid structure, that is, the bending angle of the lower support portion 43 is less than 90 degrees, and the end of the lower support portion 43 is bent outward (reversely) to form two first connecting portions 44. The two first connecting portions are located on the same plane, and a mounting hole is provided on the first connecting portion, which can be connected to the fixed bracket 3 by bolts or welding; the upper end of the first plate body 41 extends upward to form a first hook 42, and the end of the first hook 42 is bent backward 90 degrees to form a first hook 421.

[0037] The upper fixing member includes a second plate body 21, and the upper end surface of the second plate body 21 forms a locking surface for accommodating the locking of the first hook 421. The two ends of the second plate body are bent forward to form an upper support portion 23, and a first groove body 20 is formed between the two upper support portions. In this embodiment, the first groove body is also an isosceles trapezoid, that is, the bending angle of the upper support portion is less than 90 degrees. Preferably, it is the same as the bending angle of the lower support portion. The end of the upper support portion 23 is bent outward (reversely) to form two second connecting portions 24. The two second connecting portions are located on the same plane, and a mounting hole is provided on the second connecting portion for fixed connection to the back plate by bolts.

[0038] In this embodiment, the length, width and height dimensions of the upper fixing member and the lower fixing member are the same, that is, except for the hooks, the rest of the structures are the same.

[0039] Embodiment 2, on the basis of embodiment 1, is provided with a second hook 22 facing downward at the end of the upper support portion 23, and is provided with a second slot body 40 on the lower support portion 43 for accommodating the second hook 22 to be inserted and capable of moving back and forth, that is, the lower end of the first plate body 21 extends downward to form the second hook 22, and the second hook can be inserted into the second slot body 40 from top to bottom. When the first hook fits with the end surface of the first slot body, the second hook also fits with the end surface of the second slot body, which can increase the overall connection strength and is suitable for installation on a wall or ceiling with a certain inclination; after fitting, the width of the first hook is the same as the width of the end surface of the first slot body, and the width of the second hook is the same as the width of the end surface of the second slot body, avoiding the formation of left and right gaps and shaking.

[0040] Example 3. Based on Example 2, the end of the second hook is bent 90 degrees to form a second hook, which can hook the lower end of the second groove body 40. At this time, the lower end surface of the first plate body 41 forms a locking surface, which can increase the axial locking strength and reliability, and is suitable for use on walls with higher inclinations.

[0041] Embodiment 4: In embodiment 1, the upper fixing member and the lower fixing member are interchangeable, that is, the upper fixing member serves as a hook and the lower fixing member serves as a hanging slot, that is, the upper fixing member and the lower fixing member are interchangeable.

[0042] Embodiment 5: In embodiment 2, the upper fixing member and the lower fixing member are interchangeable.

[0043] The following is a brief description of the installation principle of Example 2 as a preferred embodiment:

[0044] See Figure 8 , align the upper fixing member with the lower fixing member, and insert the first hook 42 from bottom to top into the first slot 20, while the second hook 22 is inserted from top to bottom into the second slot 40 to achieve overall support for the heater; then rotate and adjust the support block 5 to move it backward, contact the wall, and push the heater forward, even if the upper fixing member moves forward, refer to Figure 9 When the heater moves to the front limit position, the end surface of the first hook contacts the end surface of the first groove body, so that the first hook 421 hooks the upper end of the first groove body, so that the upper fixing member cannot move upward and cannot produce relative movement in other directions, thereby achieving a fixed connection between the two.
