Description

Technical Field

[0001] The utility model relates to the technical field of indoor unit installation, in particular to a multi-split indoor unit installation structure. Background Art

[0002] Multi-split central air conditioner is a type of user central air conditioner, commonly known as "one to many", which refers to a primary refrigerant air conditioning system in which one outdoor unit is connected to two or more indoor units through piping, with air cooling heat exchange on the outdoor side and direct evaporation heat exchange on the indoor side. Multi-split systems are currently being used more and more widely in small and medium-sized buildings and some public buildings.

[0003] When installing the multi-split indoor unit, most of them are suspended and installed with expansion bolts, and then fixed with nuts. Since the expansion bolts are hammered into the opened holes with external tools, the lengths of the expansion bolts are different when they are hammered in and fixed. As a result, when installing the indoor unit later, a spirit level is needed to measure the level of the installed indoor unit and keep it level during installation, which increases the labor intensity of the staff. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-split indoor unit installation structure to solve the problems existing in the above-mentioned background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a multi-split indoor unit installation structure, including an indoor unit body, a fixing plate, an expansion bolt, a screw rod and a first nut for limiting the indoor unit body, and also includes:

[0006] A second nut threadedly connected to the surface of the screw, a third nut threadedly connected to the surface of the screw above the second nut;

[0007] A movable ring rotatably connected to the bottom of the third nut, the interior of the movable ring being movably connected to the surface of the screw, and an indicator rod being rotatably connected to the right side of the movable ring;

[0008] A marking structure is fixed on one side of the screw rod and is used to limit the position of the third nut.

[0009] Preferably, the marking structure includes a folding plate fixed to one side of the screw rod, an indicator plate movably connected to the inner side of the folding plate, and scale markings fixed to the surface of the folding plate.

[0010] Preferably, an indicator head is fixedly connected to one side of the indicator plate, and the indicator head is arranged in a cone shape.

[0011] Preferably, one end of the indicator plate is located above the third nut.

[0012] Preferably, a buffer plate is rotatably connected to the bottom of the second nut, and the interior of the buffer plate is movably connected to the surface of the screw.

[0013] Preferably, a gasket is movably connected to the surface of the screw rod, and the gasket is located above the first nut.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] The utility model can drive the movable ring to move on the surface of the screw by threading the third nut and the second nut respectively with the surface of the screw, so that the bottom end of the indicator rod can fit with the top of the second nut, so that the indoor unit body can be installed horizontally. At the same time, through the setting of the marking structure, the position of the third nut moving on the surface of the screw can be observed, so that the indoor unit body can be installed horizontally at different heights on the surface of the screw.

[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 1-4As shown, a multi-split indoor unit installation structure includes an indoor unit body 1 and expansion bolts 4 that are arranged through the inside of a wall, fixed plates 2 are fixedly connected to the front and rear sides of both sides of the indoor unit body 1, a screw 3 is movably connected inside the fixed plate 2, a first nut 5 for limiting the indoor unit body 1 is threadedly connected to the surface of the screw 3, a second nut 7 is threadedly connected to the surface of the screw 3, a third nut 9 is threadedly connected above the second nut 7 and to the surface of the screw 3, a movable ring 10 is rotatably connected to the bottom of the third nut 9, the interior of the movable ring 10 is movably connected to the surface of the screw 3, an indicator rod 11 is rotatably connected to the right side of the movable ring 10, and a marking structure 12 for conveniently limiting the position of the third nut 9 is fixed to one side of the screw 3.

[0023] The marking structure 12 includes a folding plate 121, an indicator plate 122 and scale lines 123. The folding plate 121 is fixed on one side of the screw 3. The back of the indicator plate 122 is movably connected to the inside of the folding plate 121. The scale lines 123 are located on the surface of the folding plate 121. In this way, the height of the third nut 9 on the surface of the screw 3 can be conveniently observed according to the position of the indicator plate 122 moving on the folding plate 121, so as to improve the stability of the subsequent indoor unit body 1.

[0024] One side of the indicator plate 122 is fixedly connected with an indicator head 13, and the indicator head 13 is arranged in a cone shape, so as to better guide the indicator plate 122 for the installation personnel to observe.

[0025] One end of the indicator plate 122 is located above the third nut 9, so that as the third nut 9 moves, the indicator plate 122 will be pushed to move together, so as to facilitate the adjustment of the installation position.

[0026] The bottom of the second nut 7 is rotatably connected to a buffer plate 8, and the interior of the buffer plate 8 is movably connected to the surface of the screw rod 3. This not only protects the second nut 7 and the fixed plate 2, but also improves the subsequent fixing effect between the second nut 7 and the fixed plate 2.

[0027] The surface of the screw rod 3 is movably connected with a gasket 6, which is located above the first nut 5, so that it not only increases the contact area but also plays a role in preventing loosening.

[0028] Working principle: When in use, first fix the expansion bolt 4 to the top of the wall, and then screw the third nut 9 into the surface of the screw rod 3. During the screwing process, as the third nut 9 moves, it can drive the indicator plate 122 to move on the surface of the folding plate 121, and observe the position of the indicator plate 122 on the surface of the scale mark 123. Then screw the second nut 7 into the surface of the screw rod 3 so that the top of the second nut 7 fits with the bottom end of the indicator rod 11. Then align the fixing plate 2 at the indoor unit body 1 with the surface of the screw rod 3 and push it in so that the top of the fixing plate 2 fits with the bottom of the buffer plate 8. Then the gasket 6 can be inserted into the surface of the screw 3, and finally the first nut 5 is screwed in to fix it.
