Description

Technical Field

[0001] This invention relates to the field of air conditioning regulation and control technology, specifically to an intelligent regulation and control device for central air conditioning based on the Internet of Things. Background Technology

[0002] Central air conditioning, also known as multi-split system or residential central air conditioning, is a system that consists of one outdoor unit connected to multiple indoor units, and delivers cool or warm air to different rooms through pipes. An air conditioner controller is a device used to control an air conditioning system. Its core function is to receive infrared signals emitted by the air conditioner and adjust the power switch, temperature, and mode accordingly to achieve automated control of the indoor environment. Currently, most air conditioner controllers on the market adopt a split structure, consisting of a front shell and a rear shell, which are connected and fixed by multiple bolts. This bolt connection method has the advantages of a robust structure and reliable connection, and performs well in ensuring the structural strength and sealing of the product, making it the mainstream choice for long-term applications. However, in actual installation, debugging and subsequent maintenance, the bolt fixing method has gradually revealed obvious drawbacks. First, the disassembly and assembly process is cumbersome. Maintenance personnel must use special screwdrivers and other tools to tighten or loosen multiple bolts one by one. The operation steps are numerous and time-consuming. Second, after multiple disassembly and assembly, there is a risk that the bolts may strip or be lost, which may affect the reliability of the shell fixing. Summary of the Invention

Each of the first abutting blocks is elastically arranged inside the corresponding first storage groove through the corresponding third return spring.

[0009] Further, first air bags are provided between the side walls of each of the first abutting blocks and the inner walls of the corresponding first storage grooves. Second storage grooves are formed at the inner tops of each of the claws, second abutting blocks are arranged inside each of the second storage grooves, and second air bags are provided between the inner tops of each of the second storage grooves and the end faces of the corresponding second abutting blocks. First exhaust pipes are formed between each of the second air bags and the corresponding first air bags.

[0010] Furthermore, each of the latches has an air storage chamber at a position corresponding to the first exhaust pipe, and a sealing plate is slidably arranged inside each air storage chamber. A fourth return spring is provided between the side wall of each sealing plate and the inner wall of the corresponding air storage chamber. The gas storage chamber has a second exhaust pipe between the side wall of the sealing plate away from the fourth reset spring and the first exhaust pipe.

[0011] Furthermore, the side wall of the second supporting block is provided with a second guide block, and the inner wall of the second receiving groove is provided with a second guide groove at the position of the second guide block, and the second guide block is slidably disposed inside the second guide groove; A third storage groove is provided on the side wall away from the second guide block inside the second guide groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the cooperation of the mounting plate and the snap-fit ​​assembly, installs the regulating controller body inside the regulating controller housing into a suitable position. During installation, the regulating controller housing is snapped onto the mounting plate, and then the snap claws are pressed into the slots. After pressing a certain distance, the second abutment block is squeezed, and the second abutment block drives the second guide block to squeeze the third abutment block. The gas inside the third airbag on one side of the third abutment block is discharged to the fourth airbag through the third exhaust pipe. The fourth airbag expands, pushing the second insertion rod into the first fixing groove, thereby limiting the snap claws and ensuring the fixing of the regulating controller housing. During maintenance, the lever is moved. At this time, with the cooperation of the oblique groove, the insertion rod is no longer limited, the fifth airbag is no longer squeezed, and the gas inside the third exhaust pipe can be discharged into the fifth airbag. At this time, the second insertion rod is moved out from the first fixing groove under the action of the fifth return spring, completing the disassembly of the regulating controller housing. It is convenient and quick, without the need for disassembly tools, achieving the purpose of rapid maintenance. 2. When the latch extends into the slot, it abuts against the second abutment block. The second abutment block compresses the second airbag, and the gas inside the second airbag is discharged into the first airbag through the first exhaust pipe. The first airbag expands, pushing the first abutment block out and applying a lateral force to the controller housing. With repeated disassembly and reassembly, the latch and the slot rub against each other, causing the thickness of their contact surface to change. A gap appears between the latch and the slot, resulting in a gap between the controller housing and the mounting plate, which makes it easy for dust to enter. The first abutment block ensures that the controller housing and the mounting plate contact tightly. Attached Figure Description
