Description

Technical Field

[0001] This utility model relates to the field of refrigeration pipe connector technology, and more specifically, to a quick-connect, high-seal refrigeration copper pipe. Background Technology

[0002] Copper pipe refrigeration is a refrigeration technology that uses copper pipes as the refrigerant transfer medium. The principle is that the copper pipes can effectively absorb heat from the surrounding air and, through the circulation of the refrigerant, transfer the heat from one end of the system to the other, thereby achieving a cooling effect.

[0003] Currently, the connection ends of refrigeration copper pipes are mainly connected using nut sleeves, which are sealed with only a single gasket inside, resulting in a generally poor sealing effect at the connection ports of refrigeration copper pipes. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a quick-connect high-seal refrigeration copper pipe, which aims to improve the problem that when the connection end of the refrigeration copper pipe is connected by a nut sleeve, only a single gasket is used for sealing inside, resulting in poor sealing effect at the connection port of the refrigeration copper pipe.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a quick-connect, high-sealing refrigeration copper pipe, including a copper pipe body and a nut.

[0007] The copper tube body is provided with a flange at its end;

[0008] The nut is fitted onto the outside of the copper tube body. A rear protruding ring is provided at the tail end of the nut. Both the outer wall of the copper tube body and the inner wall of the rear protruding ring are provided with annular grooves. A sealing ring is provided inside the annular groove. A cavity is provided inside the sealing ring. A sealing washer is provided between the flange and the inner bottom wall of the nut.

[0009] In one embodiment of this utility model, a groove that mates with a sealing gasket is provided on the outer wall of the copper tube body near the flange end.

[0010] In one embodiment of this utility model, the nut is provided with multiple sets of anti-slip ridges on its exterior.

[0011] In one embodiment of this utility model, an avoidance opening is provided between the annular groove on the inner side of the rear convex ring and the inner bottom wall of the nut.

[0012] The quick-connect high-sealing refrigeration copper pipe also includes a rotation auxiliary component, which is installed on the outside of the rear convex ring.

[0013] In one embodiment of this utility model, the rotation auxiliary component includes a strip, a fixed base, and a pin. The fixed base is fixedly connected to the rear protruding ring, and one end of the strip is rotatably connected to the fixed base via the pin.

[0014] In one embodiment of the present invention, the rotation auxiliary component further includes a clamp, which is connected to the strip and is clamped to the outside of the copper tube body.

[0015] The beneficial effects of this utility model are as follows: This utility model provides a quick-connect, high-sealing refrigeration copper pipe through the above design. The gap between the copper pipe body and the nut is sealed a second time using a combination of a sealing washer and a sealing ring, resulting in a better sealing effect compared to the traditional single-seal ring method. The cavity inside the sealing ring allows for better expansion and contraction performance, making installation easier when the sealing ring is fitted over the nut. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example

[0024] Please see Figures 1-4 This utility model provides a quick-connect, high-sealing refrigeration copper pipe, including a copper pipe body 10 and a nut 20.

[0025] The combination of the copper tube body 10 and the nut 20 provides better sealing performance compared to the traditional single-piece sealing ring.

[0026] Please see Figures 1-3 The copper tube body 10 has a flange 110 at one end. A nut 20 is fitted onto the outside of the copper tube body 10, and an integrally formed rear protruding ring 210 is provided at the tail end of the nut 20. Both the outer wall of the copper tube body 10 and the inner wall of the rear protruding ring 210 are provided with annular grooves 130, and a sealing ring 230 is provided inside the annular grooves 130, with a cavity 240 inside the sealing ring 230. A sealing washer 220 is provided between the flange 110 and the inner bottom wall of the nut 20.

[0027] The gap between the copper pipe body 10 and the nut 20 is sealed twice by using a sealing washer 220 and a sealing ring 230, which provides a better sealing effect compared to the traditional single sealing ring method. The cavity 240 inside the sealing ring 230 allows the sealing ring 230 to have better expansion performance, and it is also easier to install when the sealing ring 230 is put on the outside of the nut 20.

[0028] In the specific design, a groove 120 is provided on the outer wall of the copper tube body 10 near the flange 110 to mate with the sealing washer 220. The groove 120 makes the sealing washer 220 installed between the nut 20 and the copper tube body 10 more stable. The nut 20 has multiple sets of anti-slip ridges 250 on its exterior. The anti-slip ridges 250 increase the friction between the fingers and the nut 20, making it easier to turn the nut 20 and to assemble and disassemble it more conveniently and quickly.

[0029] Furthermore, an allowance 260 is provided between the annular groove 130 on the inner side of the rear convex ring 210 and the inner bottom wall of the nut 20. The allowance 260 is provided so that after the nut 20 is put on the outside of the copper tube body 10, it is easier to drive the annular groove 130 on the inner side of the rear convex ring 210 to be stuck on the outside of the sealing ring 230 when the nut 20 is moved.

[0030] Please see Figure 1 and Figure 4 The quick-connect, high-sealing refrigeration copper pipe also includes a rotation auxiliary assembly 30, which is installed on the outside of the rear convex ring 210. The rotation auxiliary assembly 30 includes a strip 310, a fixing seat 320, and a pin 330. The fixing seat 320 is fixedly connected to the rear convex ring 210, and one end of the strip 310 is rotatably connected to the fixing seat 320 via the pin 330. The rotation auxiliary assembly 30 also includes a clamp 340, which is connected to the strip 310 and is clamped to the outside of the copper pipe body 10.

[0031] First, rotate the strip 310 along the pin 330 until it is in the radial position of the copper tube body 10. At this time, rotating the strip 310 can drive the rear convex ring 210 and the nut 20 to rotate, increasing the torque when the nut 20 rotates. This allows for easy disassembly and assembly of the nut 20 without the use of additional tools. After disassembly and assembly, rotate the strip 310 along the pin 330 until the clamp 340 on one side of the strip 310 engages with the outside of the copper tube body 10, thus positioning and fixing the strip 310.

[0032] The working principle of this quick-connect high-sealing refrigeration copper pipe is as follows: During use, a sealing washer 220 and a sealing ring 230 are used to seal the gap between the copper pipe body 10 and the nut 20, respectively, providing a better sealing effect compared to the traditional single-ring sealing method. The cavity 240 inside the sealing ring 230 allows for better expansion and contraction performance, making installation easier when the sealing ring 230 is fitted over the nut 20.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
