[0021] Please refer to Figure 1 , the utility model provides a combined syringe barrel for a circular knitting machine, including a syringe barrel 1 and a mounting mechanism 2. The mounting mechanism 2 is arranged at the bottom of the syringe barrel 1.

[0022] Please refer to Figures 2-5, the present utility model provides a combined cylinder for a circular knitting machine. The installation mechanism 2 includes an annular mounting seat 21, a connecting sleeve 22, an inner cavity 23, an annular turntable 24, a connecting groove 25, a positioning post 26, a spring 27, a sliding button 28, a sliding groove 29, a limiting portion 210, a longitudinal groove 211 and a transverse groove 212. The annular mounting seat 21 is placed at the bottom of the cylinder 1. In the middle of the top surface of the annular mounting seat 21, a connecting sleeve 22 is integrally provided. The cylinder 1 is tightly sleeved outside the connecting sleeve 22. An inner cavity 23 is opened inside the annular mounting seat 21. The cross-section of the inner cavity 23 is annular. An annular turntable 24 is rotatably installed inside the inner cavity 23. Connecting grooves 25 are provided through both the left and right sides of the annular turntable 24. The cross-section of the connecting groove 25 is arc-shaped. Positioning posts 26 are provided on both the left and right parts of the inner cavity 23. The annular turntable 24 is sleeved and slid outside the positioning posts 26 through the connecting grooves 25. A spring 27 is installed at the end of the connecting groove 25. The tail end of the spring 27 is fixedly connected to the positioning post 26. The spring 27 plays an elastic connection role between the connecting groove 25 and the positioning post 26. A sliding button 28 is slidably installed at the front part of the annular mounting seat 21. The sliding button 28 extends into the inner cavity 23 and is fixedly connected to the front part of the annular turntable 24. The rotation of the annular turntable 24 is controlled by the sliding button 28. A sliding groove 29 is horizontally provided on the outer side wall of the connecting sleeve 22. The bottom of the sliding groove 29 is communicated with the inner cavity 23. A limiting portion 210 is slidably installed inside the sliding groove 29. And the bottom of the limiting portion 210 extends into the inner cavity 23 and is fixedly connected to the annular turntable 24. A longitudinal groove 211 is opened at the inner bottom of the cylinder 1. A transverse groove 212 is opened at the top of the longitudinal groove 211. The longitudinal groove 211 and the transverse groove 212 are perpendicular to each other. The limiting portion 210 moves along the longitudinal groove 211 to the inside of the transverse groove 212, thereby clamping and fixing the cylinder 1 on the top of the annular mounting seat 21 to achieve installation and fixation.

[0023] Further explanation, the number of the sliding grooves 29 and the limiting portions 210 is not less than 2 groups, and the sliding grooves 29 and the limiting portions 210 are equidistantly distributed on the outer side wall of the connecting sleeve 22. The number of the longitudinal grooves 211 and the transverse grooves 212 is the same as that of the sliding grooves 29 and the limiting portions 210 and their position distributions correspond to each other, ensuring the connection stability between the cylinder 1 and the annular mounting seat 21.

[0024] Further explanation, the horizontal length of the transverse groove 212 is at least 2 times the horizontal length of the limiting portion 210, ensuring that the limiting portion 210 is not easily disengaged from the transverse groove 212 by itself.

[0025] Further explanation, a rubber pad 21a is laid on the top surface of the annular mounting seat 21. The thickness of the rubber pad 21a is at least 2 mm. The rubber pad 21a plays an elastic support role between the cylinder 1 and the annular mounting seat 21, enhancing the installation stability of the cylinder 1 and making it not easily loosen and shake.

[0026] Further explanation: A calibration mark 213 is provided at the inner top end of the syringe barrel 1. The calibration mark 213 and the longitudinal groove 211 are on the same vertical line. The calibration mark 213 can help the user confirm the position of the longitudinal groove 211 and better assist the user in installation.

[0027] Further explanation: The inner diameter of the annular mounting seat 21 is not less than 90% of the inner diameter of the syringe barrel 1, which will not affect the normal discharge of the fabric in the syringe barrel 1.

[0028] The working principle is as follows:

[0029] First, install and fix the annular mounting seat 21 on the work station to ensure its stable installation without looseness.

[0030] Second, when installing the syringe barrel 1, first push the sliding button 28 to control the rotation of the annular turntable 24, so that the annular turntable 24 controls the movement of the limiting part 210 to the end of the sliding groove 29. During this process, the spring 27 will be compressed and accumulate elastic force between the positioning column 26 and the connecting groove 25. Then, put the syringe barrel 1 on the outside of the connecting sleeve 22 from top to bottom, so that the limiting part 210 is butted into the inner side of the longitudinal groove 211 until the syringe barrel 1 is placed on the top of the annular mounting seat 21. At this time, the limiting part 210 enters the inner side of the transverse groove 212 along the longitudinal groove 211. Finally, release the sliding button 28, and the elastic force of the spring 27 restoring deformation drives the annular turntable 24 to rotate and reset, so that the limiting part 210 moves to the beginning of the sliding groove 29. At the same time, the limiting part 210 will slide to the end of the transverse groove 212 to limit the upward movement of the syringe barrel 1, so as to clamp and fix the syringe barrel 1 on the top of the annular mounting seat 21 to achieve installation and fixation. The installation can be completed without the aid of external tools, and the replacement operation is convenient.

[0031] Third, when disassembling the syringe barrel 1, push the sliding button 28 to control the rotation of the annular turntable 24, so that the limiting part 210 moves to the end of the sliding groove 29. At this time, the limiting part 210 and the longitudinal groove 211 are on the same vertical line. Just lift the syringe barrel 1 upward from the surface of the connecting sleeve 22 to complete the disassembly, and the replacement operation is convenient.
