[0040] See also Figures 1 to 5 In an embodiment of the utility model, an air compressor quick-connect pipe structure comprises an air compressor pipeline 1 and a connecting pipe 2 detachably arranged at one end of the air compressor pipeline 1, a connecting assembly is arranged between the air compressor pipeline 1 and the connecting pipe 2, and under the action of the connecting assembly, the connecting pipe 2 and the air compressor pipeline 1 can be quickly disassembled and assembled;

[0041] The air compressor pipeline 1 is also provided with an elastic adjustment component, and the elastic adjustment component and the connecting component cooperate with each other to ensure that the connecting pipe 2 and the air compressor pipeline 1 are always in a pressurized and sealed state when connected.

[0042] In this solution, the connecting component and the elastic adjustment component can cooperate with each other, so that the connecting pipe 2 can quickly complete the connection with the air compressor pipeline 1, and it is also relatively convenient when disassembling, thereby improving the efficiency of the connecting pipe. In addition, the elastic adjustment component can make the air compressor pipeline 1 and the connecting pipe 2 always maintain a pressurized sealed state under the action of the connecting component, thereby ensuring the air tightness when connected.

[0043] As a further solution of the utility model, the connecting assembly includes an inner connecting pipe 3 arranged inside the air compressor pipeline 1 and a sleeve 4 slidably arranged inside the air compressor pipeline 1, and the sleeve 4 and the inner connecting pipe 3 are slidably matched with each other;

[0044] Wherein, the air compressor pipeline 1, the inner connecting pipe 3 and the sleeve 4 are all connected to each other.

[0045] In this embodiment, since the sleeve 4 is slidably disposed in the air compressor pipeline 1, and the sleeve 4 also slidably cooperates with the inner connecting pipe 3 disposed in the air compressor pipeline 1, the sleeve 4 will always remain in a connected state when sliding relative to the inner connecting pipe 3.

[0046] As a further solution of the utility model, a first annular groove 5 is formed on the outer wall of the inner connecting tube 3, and a first sealing ring 6 is arranged inside the first annular groove 5. The first sealing ring 6 can seal the gap between the inner connecting tube 3 and the sleeve 4;

[0047] A second annular groove 7 is formed at one end of the sleeve 4 away from the inner connecting pipe 3 , a second sealing ring 8 is arranged inside the second annular groove 7 , and one end of the connecting pipe 2 can be inserted into the second annular groove 7 and fit with the second sealing ring 8 .

[0048] In this embodiment, due to the presence of the first sealing ring 6, the sealing between the inner connecting pipe 3 and the sleeve 4 is ensured;

[0049] When the connecting pipe 2 and the sleeve 4 are in conflict with each other, the connecting pipe 2 and the sleeve 4 are in a sealed communication state due to the presence of the second sealing ring 8 .

[0050] As a further solution of the utility model, the inner wall of one end of the air compressor pipeline 1 close to the connecting pipe 2 is evenly provided with a plurality of grooves 9 along the circumference, and the outer wall of the connecting pipe 2 is evenly provided with a plurality of blocks 10 that can be interlocked with the plurality of grooves 9 along the circumference;

[0051] The inner wall of one end of the air compressor pipeline 1 close to the connecting pipe 2 is evenly provided with a plurality of installation slots 11 along the circumference for the plurality of the clamping blocks 10 to slide through.

[0052] In this embodiment, when installing the connecting pipe 2, first align the multiple blocks 10 on the connecting pipe 2 with the multiple installation slots 11, and then push the connecting pipe 2 to move into the air compressor pipeline 1, so that the multiple blocks 10 completely penetrate the multiple installation slots 11 respectively, and then rotate the connecting pipe 2 so that the multiple blocks 10 are aligned with the multiple slots 9 respectively, and then under the action of the elastic adjustment component, the connecting pipe 2 will drive the multiple blocks 10 outward to lock with the multiple slots 9, thereby completing the connection between the connecting pipe 2 and the air compressor pipeline 1.

[0053] As a further solution of the utility model, the inner wall of the air compressor pipe 1 is provided with a slide groove 12 along its length direction, and the outer wall of the sleeve 4 is provided with a slider 13, and the slider 13 is located inside the slide groove 12 and slidably cooperates with each other.

[0054] In this embodiment, due to the mutual sliding cooperation between the slider 13 and the slide groove 12, the sleeve 4 can only slide in the air compressor pipeline 1 but cannot rotate.

[0055] As a further solution of the utility model, the elastic adjustment assembly includes a threaded barrel 15 rotatably disposed inside the inner connecting tube 3 and a threaded rod 16 threadably matched with the threaded barrel 15, and one end of the threaded rod 16 extends to the inside of the sleeve 4;

[0056] A spring 17 is disposed inside the sleeve 4, and two ends of the spring 17 abut against one end of the threaded rod 16 and the inner wall of the sleeve 4 respectively;

[0057] Under the action of the spring 17 , the second sealing ring 8 inside the second annular groove 7 will be tightly attached to one end of the connecting pipe 2 , and the clamping block 10 will be locked with the clamping groove 9 .

[0058] In this embodiment, due to the existence of the spring 17 and the maintained compressed state, the sleeve 4 always has a tendency to move toward the clamping groove 9, and because one end of the connecting pipe 2 is in contact with the second sealing ring 8 in the second annular groove 7 on the sleeve 4, the connecting pipe 2 always has a tendency to slide out of the air compressor pipeline 1 under the action of the sleeve 4, and under the cooperation of the clamping block 10 and the clamping groove 9, the connecting pipe 2 will be firmly locked in the air compressor pipeline 1;

[0059] Since the threaded rod 16 is threadedly connected to the inside of the threaded barrel 15 and one end of the spring 17 abuts against one end of the threaded rod 16 , the spring 17 can maintain a compressed state.

[0060] As a further solution of the utility model, the inner wall of the sleeve 4 is provided with a limiting groove 18 along its length direction, and a limiting column 19 is provided at one end of the threaded rod 16. The limiting column 19 is located inside the limiting groove 18 and slides with each other.

[0061] In this embodiment, due to the mutual sliding cooperation between the limiting column 19 and the limiting groove 18, the threaded rod 16 can only slide but cannot rotate.

[0062] As a further solution of the utility model, a rotating shaft 20 is rotatably provided on the air compressor pipeline 1, a bevel gear 21 is provided at one end of the rotating shaft 20, a bevel gear ring 22 is provided on the outer wall of the threaded cylinder 15, the bevel gear 21 and the bevel gear ring 22 are meshed with each other, and a knob 23 is provided at the other end of the rotating shaft 20.

[0063] In this embodiment, the knob 23 is rotated by external force, and the bevel gear 21 will rotate along with it through the rotating shaft 20. Because the bevel gear ring 22 and the bevel gear 21 are meshed with each other, the bevel gear ring 22 will drive the threaded barrel 15 to rotate. Since the threaded barrel 15 and the threaded rod 16 are threadedly matched and the threaded rod 16 can only slide but cannot rotate, during the rotation of the threaded barrel 15, the threaded rod 16 will slide, thereby changing the compression amount of the spring 17, that is, adjusting the elasticity of the spring 17 to avoid elastic fatigue of the spring 17 after long-term use, which will not provide sufficient sealing elasticity to the connecting pipe 2 and the air compressor pipeline 1.

[0064] As a further solution of the utility model, the outer wall of the threaded tube 15 is provided with a convex ring 24, the inner wall of the inner connecting tube 3 is provided with a groove 25, and the convex ring 24 is located inside the groove 25 and rotates with each other;

[0065] The outer wall of one end of the connecting pipe 2 away from the air compressor pipeline 1 is respectively provided with a third sealing ring 14 and a connecting thread 26 .

[0066] In this embodiment, due to the mutual rotational cooperation between the protruding ring 24 and the groove 25, the threaded barrel 15 can only rotate inside the inner connecting tube 3 without displacement.

[0067] The third sealing ring 14 and the connecting thread 26 mainly serve to facilitate the connection of the pipe on the connecting pipe 2, while also ensuring the sealing during the connection.

[0068] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
