The bayonet 25 can slide into the deep groove 24 along the shallow groove 23 to connect and fix the first pipe body 11 and the second pipe body 12.

[0021] The utility model controls the first tube body 11 and the second tube body 12 to move toward each other, so that the bayonet 25 on the second connecting ring 22 slides into the shallow groove 23 and the deep groove 24 in sequence, so as to connect and fix the first tube body 11 and the second tube body 12. When disassembling, it is only necessary to control the movement of the first tube body 11 and the second tube body 12 so that the bayonet 25 slides out of the deep groove 24, and the first tube body 11 and the second tube body 12 can be disassembled. The installation process is simple and easy to operate, and it is easy to disassemble when blocked or damaged and needs to be repaired in the later stage.

[0022] The fixing method of the first tube body 11 and the first connecting ring 21 and the fixing method of the second tube body 12 and the second connecting ring 22 can both be hot-melt connection, and the specific operation is the existing technology and will not be repeated here.

[0023] The shallow grooves 23 , the deep grooves 24 and the bayonet pins 25 may be evenly arranged in multiple groups along the circumference of the first connecting ring 21 and the second connecting ring 22 , so as to more stably connect and fix the first tube body 11 and the second tube body 12 .

[0024] Preferably, sealing rings 26 are fixed on the end faces of the first connecting ring 21 and the second connecting ring 22 .

[0025] Preferably, a receiving groove 27 is provided on the end surface of the first connecting ring 21 , and the receiving groove 27 is arranged along the axial direction of the first connecting ring 21 . A shallow groove 23 and a deep groove 24 communicating with the receiving groove 27 are provided in the receiving groove 27 .

[0026] Preferably, the deep groove 24 includes a first section 28 and a second section 29, one end of the first section 28 is connected to one end of the shallow groove 23, the other end of the first section 28 is connected to one end of the second section 29, and the other end of the shallow groove 23 and the other end of the second section 29 are arranged toward the second connecting ring 22;

[0027] One end of the first section 28 is disposed close to the end surface of the first connecting ring 21, and the other end of the first section 28 is disposed away from the end surface of the first connecting ring 21;

[0028] The bayonet 25 can be extended and retracted along the depth direction of the shallow groove 23 and the deep groove 24 .

[0029] The utility model controls the first tube body 11 and the second tube body 12 to move toward each other, so that the bayonet 25 on the second connecting ring 22 slides into one end of the first section 28 of the shallow groove 23 and the deep groove 24 in sequence. Since the first section 28 is arranged obliquely, and the sealing rings 26 on the end faces of the first connecting ring 21 and the second connecting ring 22 abut against each other and seal, the first tube body 11 and the second tube body 12 can be connected and fixed. When disassembling, it is necessary to first control the first tube body 11 and the second tube body 12 to move toward each other, so that the bayonet 25 slides along the first section 28 of the deep groove 24 to the second section 29 in sequence. In this process, the two sealing rings 26 will be squeezed again due to their elasticity, and then the first tube body 11 and the second tube body 12 are controlled to move away from each other, so that the bayonet 25 slides out of the second section 29, and the first tube body 11 and the second tube body 12 can be disassembled.

[0030] The second sections 29 of the shallow groove 23 and the deep groove 24 are preferably arranged vertically.

[0031] Preferably, a chamfer 30 is formed at the other end of the shallow groove 23 , and the latch 25 can slide into the shallow groove 23 along the surface of the chamfer 30 .

[0032] The utility model provides a chamfer 30 at the other end of the shallow groove 23 , so that the latch 25 can slide into the shallow groove 23 along the surface of the chamfer 30 , and the latch 25 gradually retracts along the depth direction of the shallow groove 23 and the deep groove 24 .

[0033] Preferably, see Figure 3 The second connecting ring 22 is rotatably connected to one end of the connecting rod 31 , and the other end of the connecting rod 31 is provided with a telescopic slot 32 , in which a bayonet 25 is slidably installed via a compression spring 33 .

[0034] In the process of the latch 25 of the utility model sliding into the shallow groove 23 along the surface of the chamfer 30, the compression spring 33 gradually changes from a free state to a compressed state, and in the process of sliding from the shallow groove 23 into the deep groove 24, the compression spring 33 suddenly changes from a compressed state to a free state until it slides out of the deep groove 24.

[0035] The sealing ring 26 is provided with a receiving hole 34 for receiving the connecting rod 31 to prevent the connecting rod 31 from interfering with the sealing ring 26 when swinging around one end thereof.

[0036] Preferably, a limiting groove 35 is provided on the end surface of the second connecting ring 22, one end of the connecting rod 31 can be rotatably installed in the limiting groove 35, one side of the connecting rod 31 can overlap with one side of the limiting groove 35, the other side of the connecting rod 31 is fixed to one end of the spring sheet 36, and the other end of the spring sheet 36 is fixed to the other side of the limiting groove 35.

[0037] Before the first tube body 11 and the second tube body 12 are connected and fixed, under the action of the spring sheet 36, one side of the connecting rod 31 overlaps with one side of the limiting groove 35 to keep the connecting rod 31 horizontal, so that the bayonet 25 is kept at one end of the first section 28 of the deep groove 24, so that the bayonet 25 can slide into the shallow groove 23, thereby facilitating the installation and fixing operation.

[0038] The working principle of the utility model is as follows:

[0039] During installation, the first tube body 11 and the second tube body 12 are controlled to move toward each other, so that the bayonet 25 on the connecting rod 31 slides into the shallow groove 23 and one end of the first section 28 of the deep groove 24 through the chamfer 30 in sequence. Since the first section 28 is arranged obliquely, and the sealing rings 26 on the end faces of the first connecting ring 21 and the second connecting ring 22 abut against each other and seal, the first tube body 11 and the second tube body 12 can be connected and fixed;

[0040] When disassembling, it is necessary to first control the first tube body 11 and the second tube body 12 to move toward each other, so that the bayonet 25 slides along the first section 28 of the deep groove 24 to the second section 29 in sequence. During this process, the two sealing rings 26 will be squeezed again due to their elasticity, and the connecting rod 31 swings around one end thereof; then control the first tube body 11 and the second tube body 12 to move away from each other, so that the bayonet 25 slides out of the second section 29, and the first tube body 11 and the second tube body 12 can be disassembled;

[0041] The utility model has a simple installation process for the first tube body 11 and the second tube body 12, which is convenient to operate and can be easily disassembled when they are blocked or damaged and need to be repaired in the later stage.
