[0021] 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.

[0022] Example: Figure 1 - Figure 4 As shown, this utility model provides a technical solution for a safe and convenient quick connector, including two tube bodies 1, a connecting body 2 between the two tube bodies 1, both ends of the connecting body 2 are fixedly connected to a tapered inner tube 3, a tapered outer tube 4 is sleeved on the outside of the tapered inner tube 3, the vertical cross sections of the tapered inner tube 3 and the tapered outer tube 4 are both equilateral trapezoidal structures, one end of the tapered outer tube 4 is rotatably connected to a threaded ring 5, both ends of the connecting body 2 are provided with external threads, and the threaded ring 5 is threadedly sleeved on the external threads of the connecting body 2;

[0023] The tube body 1 is a flexible tube. First, the tapered outer tube 4 is fitted onto the outside of the tube body 1. Then, the end of the tube body 1 is fitted onto the outside of the tapered inner tube 3, and the end of the tube body 1 is opened and pressed tightly against the outer wall of the tapered inner tube 3. Then, the tapered outer tube 4 is slid so that it fits onto the outside of the tapered inner tube 3, and the inner wall of the tapered outer tube 4 and the outer wall of the tapered inner tube 3 cooperate to clamp the inner and outer walls of the tube body 1. It is threaded to the outside of the connecting body 2 through the threaded ring 5, so that the tapered outer tube 4 is pushed towards the tapered inner tube 3. The clamping force of the tapered inner tube 3 and the tapered outer tube 4 will also increase as the tapered outer tube 4 is pushed forward.

[0024] like Figure 3 As shown, the outer side of the tapered inner tube 3 is provided with a first annular groove 6 that is evenly distributed, and a first sealing ring 7 is provided in the first annular groove 6. The first sealing ring 7 is made of rubber.

[0025] After the tapered inner tube 3 is fitted onto the end of the tube body 1, the first sealing ring 7 is fitted onto the outside of the tube body 1 and positioned at the opening of the first annular groove 6. When the tapered outer tube 4 is installed, the inner wall of the tapered outer tube 4 will squeeze the first sealing ring 7 into the cavity of the first annular groove 6. In this way, the first sealing ring 7 and the inner wall of the first annular groove 6 can be used to clamp the hose, thereby increasing the sealing between the tube body 1 and the tapered inner tube 3.

[0026] like Figure 3 As shown, both ends of the connecting body 2 are provided with circumferentially arrayed wire grooves 8, and wire rods 9 are slidably connected in the wire grooves 8. The wire rods 9 are fixedly connected to the opening of the tapered outer tube 4.

[0027] The cooperation between the wire rod 9 and the wire groove 8 can increase the stability of the cooperation between the tapered outer tube 4 and the tapered inner tube 3, and avoid the impact on the clamping and sealing performance caused by the rotation of the tapered outer tube 4.

[0028] like Figure 3 As shown, the connecting body 2 includes two connecting pipes 201. The two connecting pipes 201 are respectively fixedly connected to a first long pipe 202 and a second long pipe 203 at opposite ends. A second annular groove 10 is provided on the outer side of the first long pipe 202. A limiting ring 11 is slidably sleeved on the outer side of the second annular groove 10. A threaded pipe 12 is fixedly sleeved on the outer side of the limiting ring 11. The threaded pipe 12 is threaded onto the external thread provided on the outer side of the second long pipe 203.

[0029] After installing the two connecting pipes 201 onto the ends of the two pipe bodies 1 respectively, the first long pipe 202 and the second long pipe 203 are then connected together. After that, the limiting ring 11 is rotated so that the limiting ring 11 is threaded onto the outside of the second long pipe 203. Thus, the connection and fixation of the first long pipe 202 and the second long pipe 203 can be completed, and the connection and fixation between the two pipe bodies 1 can also be completed.

[0030] As Figure 3 The conical inner tube 3 is fixedly connected with a plug-in pipe 13 at one end away from the connecting body 2, and the conical outer tube 4 is fixedly connected with an abutting ring 14 at one end away from the connecting body 2, the abutting ring 14 being sleeved on the outer side of the plug-in pipe 13.

[0031] As Figure 2 - Figure 4 A sealing groove 15 is formed between the first long pipe 202 and the second long pipe 203, and a second sealing ring 16 is arranged in the cavity of the sealing groove 15.

[0032] The second sealing ring 16 is made of rubber, and is used to improve the sealing performance between the first long pipe 202 and the second long pipe 203.

[0033] As Figure 2 - Figure 4 The first long pipe 202 is fixedly connected with a plurality of circumferentially distributed stabilizing blocks 17 at one end of the second long pipe 203, the second long pipe 203 is formed with a stabilizing groove 18 at a position corresponding to each stabilizing block 17, the stabilizing groove 18 is in plug-in connection with the stabilizing block 17, and the stabilizing block 17 is located on the outer side of the sealing groove 15.

[0034] When the first long pipe 202 and the second long pipe 203 are butted, the stabilizing block 17 is inserted into the cavity of the stabilizing groove 18, so that the first long pipe 202 and the second long pipe 203 cannot rotate relative to each other, thereby improving the stability of the butt joint between the first long pipe 202 and the second long pipe 203.

[0035] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of equivalent elements of the claims are intended to be embraced therein. Any reference signs in the claims should not be considered as limiting the claims involved.
