[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 The diagram shows an easily detachable automotive air conditioning system pipe connection pressure plate, including a pressure plate 1 and a snap-fit ​​structure 2 installed on the front end face. The front end face of the pressure plate 1 at the top position has a condensing air interface 102, and the front end face of the pressure plate 1 at the bottom position has a refrigerant interface 103. The snap-fit ​​structure 2 includes a conical sleeve 201 and a tensioning spring block 202. The conical sleeve 201 is fixedly connected to the front end face of the pressure plate 1. The condensing air interface 102 and the refrigerant interface 103 are both slidably fitted with a pressure-bearing ring 203. The front end face of the pressure-bearing ring 203 is fixedly connected to several annularly arranged tensioning spring blocks 202. The front end face of the tensioning spring block 202 has a stepped groove 205. Two pressing structures 3 are fixedly connected to one outer wall of the pressure plate 1.

[0016] It is worth noting that when connecting the refrigerant line and air line to the pressure plate 1, the line interfaces can be aligned with the condenser-air interface 102 and the refrigerant interface 103 and pushed in. As the line is pushed in, the tensioning spring 202 will be compressed and elastically deformed, causing the retaining pin 207 to slide within the limiting guide groove 304. When the retaining pin 207 slides to the retaining hole 303, due to the elastic force of the compression spring 206, the retaining pin 207 will spring into the retaining hole 303, thereby achieving a fixed connection between the line and the pressure plate. To disassemble the line, The system can be operated via a pressing structure 3, which includes a button spring plate 301 and a pressing rod 302. The button spring plate 301 is fixedly connected to the side wall of the pressure plate 1 located in the locking hole 303, while the pressing rod 302 is slidably inserted into the locking hole 303. When it is necessary to disassemble the pipeline, the button spring plate 301 can be pressed, causing the pressing rod 302 to push the locking pin 207 out of the locking hole 303, thereby realizing the disassembly of the pipeline. The refrigerant pipeline can be sleeved on the outer surface of the refrigerant connecting pipe 5, and the condensing air pipeline can be sleeved on the outer surface of the condensing air connecting pipe 4.

[0017] Please see Figure 3 and Figure 4The snap-fit ​​structure 2 also includes a gasket 204. Gaskets 204 are fixedly installed inside the rear end positions of the condensing air interface 102 and the refrigerant interface 103. Gaskets 204 are fixedly connected to a pressure ring 203 by a compression spring 206. A groove 208 is provided on the outer wall of the pressure ring 203. A snap post 207 is fixedly connected to the inner surface of the groove 208 by a snap spring 209. A snap hole 303 matching the snap post 207 is provided on the side wall of the pressure plate 1.

[0018] When the pipe is pushed into the condenser air inlet 102 or the refrigerant inlet 103, the pressure ring 203, as the primary contact component, achieves reliable fixation of the retaining post 207 through the cooperation of the groove 208 on its outer wall and the retaining spring 209. This design allows the retaining post 207 to slide smoothly along the groove 208 and exit the retaining hole 303 when subjected to external force, such as the pressing operation when disassembling the pipe, without causing disassembly difficulties due to uneven force or jamming. The pressure spring 206 allows the tensioning spring block 202 to return to its original state when it is not clamping, ensuring its next use.

[0019] Please refer to Figure 2 The pressure plate 1 has two countersunk holes 101 at its center. These countersunk holes 101 are used to securely install the pressure plate 1 to a predetermined position in the automotive air conditioning system. During installation, bolts or other fasteners pass through the countersunk holes 101 and connect to the frame or other components of the automotive air conditioning system, ensuring the firmness and stability of the pressure plate 1. This design avoids using traditional countersunk holes 101, increasing its firmness and preventing individual countersunk holes 101 from easily rotating and deviating from their original position.

[0020] See Figure 3 and Figure 4 The inner walls of both the condenser air interface 102 and the refrigerant interface 103 are provided with limiting guide grooves 304. The locking post 207 is slidably connected inside the limiting guide groove 304. The limiting guide groove 304 is connected to the locking hole 303. When the locking post 207 slides in the limiting guide groove 304, it can be guided by the limiting guide groove 304 to ensure that the locking post 207 moves smoothly along the predetermined path and avoids deviation or jamming. This design not only improves the smoothness of the disassembly process, but also enhances the stability and reliability of the connection. The end of the limiting guide groove 304 is connected to the locking hole 303, so that when the locking post 207 slides to the end of the limiting guide groove 304, it can smoothly enter the locking hole 303 to achieve a firm connection between the pipeline and the pressure plate.

[0021] See Figure 3 and Figure 4The pressing structure 3 includes a button spring plate 301. The pressure plate 1 is fixedly connected to the button spring plate 301 on the side wall of the card hole 303. A pressing rod 302 is fixedly connected to the inner side of the button spring plate 301. The pressing rod 302 is slidably inserted into the card hole 303, and the end of the pressing rod 302 contacts the card post 207. When the operator presses the button spring plate 301, the pressing rod 302 pushes the card post 207, causing it to move along the card hole 303 towards the limiting guide groove 304. When the card post 207 completely slides out of the card hole 303 and enters the limiting guide groove 304, the connection between the pipeline and the pressure plate 1 is released. At this time, the operator can easily disassemble the pipeline. This pressing structure 3 design simplifies the disassembly process, improves the operating efficiency, and ensures the stability and safety of the disassembly process.

[0022] The component size of the lower snap-fit ​​structure 2 is smaller than that of the upper snap-fit ​​structure 2. Since the size of the refrigerant pipe is smaller than that of the air pipe, the installation of the two pipe sizes is made to fit together.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
