[0022]

[0023]

[0024] Assembly instructions: The HVAC installation and fixing structure of the present application mainly includes a fixing frame, a front limit push plate 4, a side limit push plate 5 and a movable plate 7. The specific assembly steps are as follows: weld the support plate 3 and the back plate 1 to fix them, and punch fixing holes on the back plate 1 for fixing them to the wall; fix the sliding plate 12 and the bottom support plate 9 to the inner side of the front limit push plate 4, and make the sliding plate 12 slidably connected in the slide rail 11, and then fix the slide rail 11 to the lower surface of the support plate 3, and install the pulley 17 at the front end bottom of the bottom support plate 9; fix the movable block 14 to the lower surface of the side limit push plate 5, and then insert the movable block 14 into the movable opening 13, snap the pulley 17 into the transmission opening 16 of the transmission plate 15, and fix the transmission plate 15 and the movable block 14, install the universal ball 8 on the surface of the movable plate 7, and then slide the movable plate 7 into the opening 6, and support the bottom of the movable plate 7 through the bottom support plate 9.

[0025] After the fixing bracket is fixed to the wall, the external unit 2 can be installed. It can be understood that the slot 18 on the side of the external unit 2 is set without destroying the structure of the external unit 2 itself. The slot 18 can be set by first opening the slot 18 on the steel plate and then fixing the steel plate on the side of the external unit 2.

[0026] The working principle of the utility model is:

[0027] During installation, first fix the back plate 1 on the wall to complete the installation of the fixing frame, then place the external unit 2 on the surface of the support plate 3, so that the two sides of the external unit 2 are located between the two side limit push plates 5, and the front and rear sides of the external unit 2 are located between the back plate 1 and the front limit push plate 4, and then push the front limit push plate 4 to drive the bottom support plate 9 to move inward. When the bottom support plate 9 moves, it drives the transmission plate 15 to move inward through the pulley 17, thereby driving the two side limit push plates 5 to move closer to each other, so that the external unit 2 can be quickly positioned on the surface of the support plate 3. In addition, by setting the universal ball 8 on the surface of the movable plate 7, it can It is enough to reduce the friction between the bottom of the external unit 2 and the support plate 3, which is more labor-saving. When the bottom support plate 9 moves to the innermost end, the accommodating groove 10 is just exposed at the bottom of the movable plate 6, so that the accommodating groove 10 automatically moves downward, so that the external unit 2 can be stably stopped on the surface of the support plate 3. It is worth mentioning that when the front limit push plate 4 and the side limit push plate 5 reach the specified position, the inner block 19 is just inserted into the groove 18 on the side of the external unit 2, thereby limiting the external unit 2 in the vertical direction. Finally, the front limit push plate 4 and the support plate 3 are connected by bolts 20.

[0028] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
