Description

Technical Field

[0001] The utility model relates to the technical field of central air-conditioning installation, in particular to an auxiliary fixing frame for central air-conditioning installation. Background Art

[0002] The central air-conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. It uses the principle of liquid vaporization refrigeration to provide the required cooling capacity for the air conditioning system to offset the heat load of the indoor environment; the heating system provides the required heat for the air conditioning system to offset the cooling and heating loads of the indoor environment.

[0003] During the installation of central air conditioners, the outdoor unit is generally installed through a fixed bracket or a ground mounting platform. No matter which method is used, it will be installed close to the wall to achieve the purpose of convenient installation and saving external space. When installing the outdoor unit, the current fixed bracket directly places the outdoor unit on the top surface of the fixed bracket. Since the fixed bracket is installed at a high position on the wall and the outdoor unit is placed on the top of the fixed bracket, the staff needs to move the outdoor unit little by little so that the mounting hole of the outdoor unit is aligned with the mounting hole of the fixed bracket for easy installation. However, this kind of pushing work brings inconvenience to the installers. Utility Model Content

DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1-4 As shown, an auxiliary fixing frame for installing a central air conditioner includes two left and right mounting frames 1 mounted on the wall, and a placement frame 2 is welded between the two mounting frames 1, fixing holes 3 are opened on both sides of the front of the top of the placement frame 2, an air conditioner outdoor unit body 4 is arranged on the top of the placement frame 2, a fixing plate 5 is fixedly connected to the bottom of the placement frame 2, a first crank 6 is arranged below the fixing plate 5, a screw rod 7 is fixedly connected to the top of the first crank 6, and the top of the screw rod 7 is rotatably connected to the bottom of the placement frame 2, a movable plate 8 is threadedly connected to the surface of the screw rod 7, both ends of the movable plate 8 extend to the inside of the placement frame 2 and are fixed with a support plate 9, a plurality of rollers 10 are rotatably connected to the inside of the support plate 9, and the front of the placement frame 2 A bidirectional screw 11 is rotatably connected, and screw sleeves 12 are threadedly connected on both sides of the surface of the bidirectional screw 11. A connecting plate 13 is fixed to the bottom of the screw sleeve 12. The top surface of the other end of the connecting plate 13 is flush with the top surface of the placement rack 2, so that it will not affect the movement of the push plate 14, thereby facilitating the subsequent push plate 14 to limit the air-conditioning outdoor unit body 4. A push plate 14 is fixed to the other end of the connecting plate 13, and a soft pad 17 is provided on the side of the push plate 14 close to the air-conditioning outdoor unit body 4, and the soft pad 17 is made of rubber, so that when the surface of the air-conditioning outdoor unit body 4 is limited, its surface can be prevented from being worn. A force-applying structure 16 for driving the bidirectional screw 11 to rotate is provided in front of the placement rack 2.

[0023] The force-applying structure 16 includes a second crank handle 161, a first bevel gear 162 and a second bevel gear 163. The second crank handle 161 is arranged in front of the placement rack 2. The back side of the second crank handle 161 is fixed to one side of the first bevel gear 162 through a rotating rod. The other side of the first bevel gear 162 is meshed with the second bevel gear 163. The interior of the second bevel gear 163 is fixed to the surface of the bidirectional screw 11. In this way, when the bidirectional screw 11 is driven to rotate, the second crank handle 161 can be rotated, and the first bevel gear 162 can be driven to rotate through the rotating rod, thereby driving the second bevel gear 163 to rotate, and driving the bidirectional screw 11 to rotate.

[0024] Fixed rods 15 are fixed on both the left and right sides of the placement rack 2, and the inside of the connecting plate 13 is movably connected to the surface of the fixed rods 15, so that the connecting plate 13 can be auxiliary limited to facilitate its left and right movement.

[0025] Movable rods 18 are fixedly connected on both sides between the bottom of the placement rack 2 and the top of the fixed plate 5. The surface of the movable rods 18 is movably connected to the inside of the movable plate 8, so that the movable plate 8 can be auxiliary supported and its stability can be maintained when it moves up and down.

[0026] It is worth noting that: the technical features proposed in this technical solution should be regarded as prior art, and the specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field, and this technical solution will not be further elaborated.

[0027] Working principle: When in use, first, the mounting frame 1 is fixed on the surface of the outer wall, and then the first crank handle 6 is rotated, and the screw rod 7 is driven to rotate, thereby driving the movable plate 8 and the support plate 9 to move upward, so that the roller 10 is exposed above the placement frame 2, and then the air-conditioning outdoor unit body 4 is placed on the placement frame 2 and contacts with the roller 10, and according to the position after placement, the bidirectional screw rod 11 can be driven to rotate by the force structure 16, and at the same time, the left and right screw sleeves 12 and the connecting plate 13 are driven to move toward the opposite side, so that the push plate 14 pushes the air-conditioning outdoor unit body 4 to the middle position. After pushing to the middle position, the first crank handle 6 can be rotated again, and the screw rod 7 can be driven to flip and rotate, so that the movable plate 8, the support plate 9 and the roller 10 return to the inner side of the placement frame 2, and then the bottom surface of the air-conditioning outdoor unit body 4 will directly contact the top surface of the placement frame 2, and finally the air-conditioning outdoor unit body 4 and the fixing hole 3 can be fixed by bolts.
