DETAILED DESCRIPTION

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-3 A reversing valve assembly structure includes a valve body 1 and a magnetic controller 6. The valve body 1 is provided with a connecting pipe 3 through a connecting port 2. The inner wall of the connecting port 2 is provided with a limiting groove 7. The connecting port 2 is provided with a disassembly port 4 communicating with the limiting groove 7 and a positioning hole 5. The connecting pipe 3 is provided with a disassembly block 8. The disassembly block 8 is provided with a pressing groove 9. The pressing groove 9 is provided with a positioning block 10 through a pressing mechanism. The connecting pipe 3 is provided with a rotating groove 13, a rotating cavity 15 and an air cavity 16. The rotating cavity 15 is provided with a screw 17 extending into the rotating groove 13. The inner wall of the connecting port 2 is provided with a rack 12. The screw 17 is connected to the rack 12 through a transmission mechanism. The air cavity 16 is provided with a piston plate 19. The piston plate 19 is connected to the screw 17 through a connecting mechanism. The connecting pipe 3 is provided with a sealing airbag 21 communicating with the air cavity 16. The inner wall of the connecting port 2 is provided with a sealing groove 20.

[0022] The extrusion mechanism includes a spring 11 disposed in the extrusion groove 9, with both ends of the spring 11 connected to the outer wall of the positioning block 10 and the inner wall of the extrusion groove 9, respectively. The elastic potential energy provided by the spring 11 enables the extrusion of the positioning block 10, so that when the disassembly block 8 corresponds to the positioning hole 5, the positioning block 10 is extruded into the positioning hole 5.

[0023] The transmission mechanism includes a gear 14 disposed in the rotating groove 13 and connected to the screw 17, and the gear 14 meshes with the rack 12. The rack 12 is designed in an arc shape. When the connecting pipe 3 rotates in the connecting port 2, the gear 14 will rotate under the action of the rack 12, thereby driving the screw 17 to rotate.

[0024] The connecting mechanism includes a connecting frame 18 threaded onto the screw 17, with one end of the connecting frame 18 fixedly connected to the piston plate 19. As shown in the figure, the connecting frame 18 has a U-shaped design, with both ends fixedly connected to the piston plate 19. The piston plate 19 is slidably and sealed within the air chamber 16, and there is gas between the piston plate 19 and the air chamber 16.

[0025] There are four disassembly ports 4 and four positioning holes 5, all evenly spaced circumferentially, with the four disassembly ports 4 and positioning holes 5 staggered. After the disassembly block 8 enters the limiting groove 7 through the disassembly port 4, the connecting pipe 3 rotates 45 degrees and the disassembly block 8 will align with the positioning hole 5.

[0026] The vertical cross-section of the sealing groove 20 is T-shaped, and the vertical cross-section of the sealing airbag 21 is also T-shaped. This shape design allows for a larger contact area between the sealing groove 20 and the sealing airbag 21, resulting in a better sealing effect.

[0027] Components not specifically described in this utility model are all standard parts and can be purchased from the market. The specific connection methods for each component all employ mature methods from the prior art, and will not be detailed here. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0028] When this utility model is in use, the connecting pipe 3 is in the connecting port 2 and is connected to the valve body 1 for normal operation. The disassembly block 8 is in the limiting groove 7, corresponding to the positioning hole 5 and offset from the disassembly port 4. The positioning block 10 is in the positioning hole 5 to prevent the connecting pipe 3 from rotating in the connecting port 2. The piston plate 19 is in the air chamber 16 on the side close to the sealing airbag 21. The gas in the air chamber 16 is in the sealing airbag 21. The sealing airbag 21 is in the inflated state and is in the sealing groove 20, ensuring a stable and sealed connection between the connecting pipe 3 and the connecting port 2.

[0029] When it is necessary to disassemble the connecting pipe 3, press the positioning block 10 in the positioning hole 5 to compress the spring 11 and enter the squeezing groove 9. Then rotate the connecting pipe 3 relative to the valve body 1 and the connecting port 2, so that the disassembly block 8 is misaligned with the positioning hole 5 and corresponds to the disassembly block 8. During this process, the rack 12 causes the gear 14 and the screw 17 to reverse, the piston plate 19 moves and resets, and the gas in the sealing airbag 21 returns to the air chamber 16 and collapses. Then, since the disassembly block 8 is now aligned with the disassembly port 4, the connecting pipe 3 loses its limit and can be directly pulled away from the connecting port 2, thus completing the disassembly of the connecting pipe 3.

[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
