Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning box installation devices, in particular to a hanging type air-conditioning box installation bracket. Background Art

[0002] An air conditioning box is a unit formed by installing air filters, surface coolers, heaters, humidifiers and other air treatment components in a vertical or horizontal cabinet. In order not to occupy the effective space in the venue, theaters, cinemas and other places generally adopt a hoisting installation method for air conditioning boxes. The existing hoisting structure usually sets a hanger on the floor, sets a support plate at the bottom of the hanger, and the air conditioning box is installed on the support plate, so that the air conditioning box is suspended in the air. When the air conditioning box is working, the air conditioning box vibrates due to air flow or other factors, further generating noise, and the noise cannot be attenuated by simply suspending it in the air with a hanger and a support plate. The utility model patent with authorization announcement number CN216867408U discloses a vibration-damping hoisting structure for an air-conditioning box, including an embedded component arranged on a floor slab and a suspension component for suspending the air-conditioning box. The suspension component is connected to the embedded component through a connecting component. The connecting component includes a connecting frame and a vibration-damping part installed on the connecting frame. The top of the connecting frame is connected to the embedded component. The suspension component is elastically connected to the connecting frame through the vibration-damping part. It can perform three times of vibration reduction and has the effect of weakening the transmission of vibration and reducing noise. However, the structural stability is poor, the amount of shaking increases during use, and there are certain safety hazards. Utility Model Content

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A hanging type air-conditioning box mounting bracket comprises a supporting frame hung at the bottom of a floor slab, a shock-absorbing supporting frame is arranged on the supporting frame, and the air-conditioning box is mounted on the top of the shock-absorbing supporting frame; the shock-absorbing supporting frame comprises a plurality of shock absorbers mounted on the supporting frame, a mounting base plate arranged on the top of the shock absorbers and a rubber shock-isolating pad fixedly arranged on the top of the mounting base plate, and the air-conditioning box is mounted on the top of the rubber shock-isolating pad; a plurality of limit assemblies are arranged between the mounting base plate and the supporting frame, and the limit assemblies are used to limit the maximum separation interval between the mounting base plate and the supporting frame.

[0006] Preferably, the support frame includes an adapter fixed to the bottom of the floor slab, a support rod adjustably arranged on the adapter, and a support plate adjustably arranged at the bottom of the support rod.

[0007] Preferably, the adapter is S-shaped, and the top of the support rod is connected to the adapter by a nut.

[0008] Preferably, two layers of rubber vibration isolation pads are provided.

[0009] Preferably, the limit assembly includes a limit screw fixedly installed at the bottom end on the support frame, a rubber sleeve sleeved on the limit screw, and a limit locking nut fixedly arranged on the limit screw. The rubber sleeve is fixedly installed on the mounting base plate, and the limit screw can slide in the rubber sleeve.

[0010] Preferably, the shock absorber is a metal shock pad.

[0011] In the present utility model, the provided shock absorber and rubber vibration isolation pads play a dual role of shock absorption and noise reduction, greatly performing shock absorption and noise reduction operations, improving the safety during use. The shock absorber adopts a metal shock pad to avoid shaking caused by the use of springs and has good structural stability. The provided adapter is S-shaped, which increases the connection length and adjustment length of the support rod. The provided limit assembly can prevent the loosening of the shock absorber caused by long-term use, improve the shock absorption effect, reduce the maintenance frequency. The provided rubber sleeve solves the problem of noise generated by direct contact of metal parts during the shock absorption process and improves the service life of the device.
