Technical Field

[0001] The utility model relates to the technical field of central air-conditioning installation, in particular to a central air-conditioning indoor unit installation device. Background Art

[0002] Compared with split air conditioners, the installation process of central air conditioners is more complicated, and issues such as airflow organization and pipeline direction need to be considered. In order to facilitate the installation of the central air conditioner indoor unit, a central air conditioner indoor unit installation device is required.

[0003] In the existing indoor unit installation process, if Figure 6 As shown, four threaded bolts are usually fixed on the top of the wall, and then nuts and ring washers are installed on the threaded bolts. Then, the four hanging corners of the chassis are respectively engaged with the upper ends of the nuts, and then the nuts are tightened to fix them.

[0004] However, during the engagement process, since the width of the hanging corners is fixed, the staff needs to engage the four corners one by one, and when installing the two hanging corners, due to the limit at the front end, the chassis needs to be tilted before it can be hung and engaged. During installation, the staff needs to proceed at a certain height, and due to the weight of the chassis, it is inconvenient for the staff to install.

[0005] Therefore, it is necessary to provide a central air-conditioning indoor unit installation device to solve the above technical problems. Utility Model Content

[0006] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a central air-conditioning indoor unit installation device that can fix the four corners of the chassis at the same time and does not need to be installed at an angle, which provides convenience during installation.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0009] Preferably, the ceiling mechanism comprises: a threaded rod, a topping column is provided at the upper end of the threaded rod, a spring washer and an annular washer are provided at the lower end of the threaded rod, and a nut is provided at the lower end of the annular washer.

[0010] Preferably, the fixed frame comprises: a fixed frame, an articulated block is provided at the end of the fixed frame, the articulated block is hinged to a movable support rod, and the movable support rod rotates at one end of the fixed frame.

[0011] Preferably, a threaded hole is provided at the end of the movable support rod, one end of the threaded hole is matched with a threaded bolt provided at the bottom end of the fixed frame, and the movable support rod is fixed to the threaded bolt.

[0012] Preferably, a concave hole is provided at the upper end of the fixing frame, and a level is horizontally placed inside the concave hole.

[0013] Preferably, a baffle is provided on the upper end surface of the fixed frame, an ash baffle box is provided inside the baffle, and the ash baffle box is slidably connected inside the baffle.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] (1) The utility model can adjust the width of the annular sheets at both ends by using the fixed box, the fixed plate, the moving block and the threaded rotating rod in coordination. In actual use, by adjusting the width of the annular sheet, the four corners of the chassis can be simultaneously penetrated into the threaded bolt, and then the width of the annular sheet can be reduced to achieve engagement. Compared with the existing one-by-one engagement method, this method is more convenient and quick during installation;

In the actual installation process, the movable support rod is rotated to 90 degrees, and then the chassis is placed, so that the chassis can be completely embedded in the fixed frame and avoid bumps during installation;

[0017] (3) The utility model uses a baffle plate in conjunction with a dust shield box. Since the chassis is at the lower end of the wall top, after long-term use, some dust will float down from the wall top. Excessive dust may clog the air intake grille of the air conditioner, affecting the normal circulation of air, thereby reducing the working efficiency of the air conditioner. Secondly, after the dust enters the chassis, it may adhere to various components of the machine, including fans, heat exchangers, etc. Long-term accumulation may cause component performance degradation or even failure. The dust can be collected and processed by the dust shield box to prevent this from happening. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0026] First embodiment:

[0027] like Figure 1-5As shown, the central air-conditioning indoor unit installation device provided by the utility model includes: a fixed frame 100, a ceiling mechanism 400, a plurality of limit boxes 200 are provided on the upper end surface of the fixed frame 100, and a chassis 300 is installed inside the fixed frame 100, the limit box 200 includes: a fixed box 210, two fixed plates 220 are installed inside the fixed box 210, a moving block 230 is provided at one end of the fixed plate 220, a ring sheet 240 is provided inside the moving block 230, and a threaded rotating rod 231 is provided at one end of the moving block 230. In actual use, the staff first fixes the plurality of threaded rods 410 on the top of the wall. After fixing, the chassis 300 is placed inside the fixed frame 100, and then the limit box 200 is adjusted. In the actual adjustment process, the staff By rotating the threaded rotating rod 231, the rotating block 230 at one end moves toward the other end, and the rotating block 230 at the other end is in a fixed state. The annular piece 240 is fixed to the inside of the moving block 230 by bolts. By moving the moving block 230, the width of the annular pieces 240 at both ends can be adjusted so that the width at both ends is as wide as the width of the annular gasket 430 in the threaded rod 410. When the four corners are adjusted, the chassis 300 only needs to be pushed vertically upward until the limit box 200 passes through the annular gasket 430, and then the threaded rotating rod 231 is rotated to shrink the width of the annular piece 240, and then the nut 440 is rotated to limit the annular gasket 430 and clamp the spring gasket 420, so that the four corner limit boxes 200 are fixed at the same time.

[0028] By using the fixed box 210, the fixed plate 220, the moving block 230 and the threaded rotating rod 231 in coordination, the width of the annular sheet 240 at both ends can be adjusted. In actual use, by adjusting the width of the annular sheet 240, the four corners of the chassis 300 can be simultaneously penetrated into the threaded bolt 131, and then the width of the annular sheet 240 can be reduced to achieve engagement. Compared with the existing hook 301, this method can achieve simultaneous engagement of the four corners, making the installation process more convenient and quick.

[0029] Second embodiment:

[0030] like Figure 3As shown, the fixed frame 100 includes: a fixed frame 110, an articulated block 120 is provided at the end of the fixed frame 110, the articulated block 120 is hinged with a movable support rod 130, the movable support rod 130 rotates at one end of the fixed frame 110, a threaded hole is provided at the end of the movable support rod 130, one end of the threaded hole is adapted to a threaded bolt 131 provided at the bottom end of the fixed frame 110, and the movable support rod 130 is fixed to the threaded bolt 131. Since the chassis 300 is relatively heavy, it is inconvenient to place it in the fixed frame 110 for fixing. During the installation process, the movable support rod 130 is used in conjunction with the hinge block 120 to realize the rotation of the movable support rod 130 on the fixed frame. In the actual installation process, the movable support rod 130 is rotated to 90°, and then the chassis 300 is placed in, and then it is rotated 90° again, and then fixed by the threaded bolt 131. Through the rotatable movable support rod 130, compared with the support rod fixed by welding, this method can make the chassis 300 completely embedded in the fixed frame and avoid bumps during installation.

[0031] Third embodiment:

[0032] like Figure 2-3 As shown, a recessed hole 140 is provided at the upper end of the fixing frame 110, and a spirit level is placed horizontally inside the recessed hole 140. In actual use, if the indoor unit is not correctly and horizontally hoisted, serious resonance problems may occur during the operation of the equipment, which will greatly affect the operating efficiency and life of the air conditioner. By placing a spirit level in the recessed hole 140 provided in the fixing frame 110, during the actual installation process, the staff needs to install the chassis 300 at a certain height, and due to the volume of the chassis 300, it is inconvenient for the staff to use the spirit level at the same time during the installation. However, through the recessed hole 140, during the installation process, the staff can place the spirit level in the recessed hole 140 in advance. Since the recessed hole 140 and the fixing frame 110 are horizontal, the chassis 300 is placed horizontally in the fixing frame 110. During installation, it is only necessary to adjust the angle through the spirit level in the recessed hole 140.

[0033] Fourth embodiment:

[0034] like Figure 1-3As shown, a baffle 150 is provided on the upper end surface of the fixed frame 110, and a dust box 160 is provided inside the baffle 150. The dust box 160 is slidably connected in the baffle 150. In actual use, the baffle 150 and the dust box 160 are used in coordination to collect wall dust. Since the chassis 300 is at the lower end of the wall top, after long-term use, some dust from the wall top will float downward. Excessive dust may block the air intake grille of the air conditioner, affecting the normal circulation of air, thereby reducing the working efficiency of the air conditioner. Secondly, after entering the chassis 300, the dust may adhere to various components of the machine, including fans, heat exchangers, etc. Long-term accumulation may cause the performance of the components to decline or even malfunction. The dust can be collected and processed by the dust blocking box 160, which can prevent dust from falling into the chassis 300. When a lot of dust accumulates in the dust blocking box 160, it only needs to be pulled out for cleaning.

[0035] Working principle: the staff first fixes a plurality of threaded rods 410 on the top of the wall, and then places the chassis 300 inside the fixed frame 100, and adjusts the limit box 200. In the actual adjustment process, the staff can adjust the width of the annular pieces 240 at both ends by rotating the threaded rotating rod 231, so that the width of the two ends is as wide as the width of the circular gasket 430 in the threaded rod 410. When the four corners are adjusted, it is only necessary to push the chassis 300 vertically upward until the limit box 200 passes through the circular gasket 430, and then shrink the width of the annular piece 240 by rotating the threaded rotating rod 231, and then fix the four corner limit boxes 200 at the same time through the limit of the circular gasket 430. The above embodiment is only one of the preferred embodiments of the utility model, and should not be used to limit the protection scope of the utility model. Any changes or modifications made to the main design concept and spirit of the utility model without any substantial meaning, and the technical problems solved by them are still consistent with the utility model, should be included in the protection scope of the utility model.
