[0002] A gas chromatograph refers to a chromatographic analysis instrument using gas as the mobile phase, which can be used for instrument analysis experiments in chemical engineering, bioengineering, and food majors, and can also be used for scientific research and routine analysis. When actually using a gas chromatograph, a bracket is needed to complete the support and fixation of the gas chromatograph. The actual use has the advantages of simple operation, stable structure, and good support effect.

[0003] The prior art discloses a gas chromatograph mounting bracket with the publication number of CN220366147U. For the above-mentioned utility model, a moving frame and a sealing ring are needed to complete the protection of the universal wheels installed at the lower part of the support frame to prevent impurities from contacting the universal wheels. However, when the gas chromatograph needs to be moved, the universal wheels will still contact the impurities on the ground. And when the universal wheels are damaged by collision, the gas chromatograph cannot be moved and used continuously, reducing the practicality of the utility model. At the same time, there is no connection structure between the support frame and the gas chromatograph. The sizes of gas chromatographs are various, and the support frame cannot adapt to the stable installation of gas chromatographs of various sizes, bringing potential hazards to the stable use of this utility model gas chromatograph.

[0004] Therefore, we propose a mobile gas chromatograph bracket to solve the above drawbacks. Summary of the Utility Model

An electric control box is installed on the end face of the mobile frame, and a control panel and a storage battery are installed inside the electric control box. Four groups of concave plates are installed at the lower part of the mobile frame. A connecting shaft passes through the left two groups of concave plates and the right two groups of concave plates through bearings.

[0029] Specifically, the two synchronous pulleys 9 are both located on the same vertical plane.

[0030] In this implementation manner: It is avoided that the synchronous belt 10 cannot be sleeved and used due to the misalignment of the two synchronous pulleys 9.

[0031] Specifically, multiple groups of air ducts 18 are fixedly penetrated through the inner top surface of the air storage tank 2, and electromagnetic valves are arranged on the side walls of the multiple groups of air ducts 18. Suction cups 12 are installed at the upper ends of the multiple groups of air ducts 18. An air inflation pump 13 is installed on one side of the movable frame 1, and an air extraction pump 14 is installed on the other side of the movable frame 1. Connecting pipes 15 are clamped to the output ends of both the air inflation pump 13 and the air extraction pump 14.

Only its use is involved without modification, so the control method and circuit connection will not be described in detail.

[0041] Working principle:

[0042] When actually using the mobile gas chromatograph support, when the four sets of universal wheels 8 in contact with the ground are contaminated by impurities or damaged by collision, the self-locking motor 11 is operated by using the control panel. The output end of the self-locking motor 11 drives a set of left connecting shafts 5 to rotate. The rotating set of left connecting shafts 5 can drive a set of right connecting shafts 5 to rotate through two sets of synchronous pulleys 9 and a synchronous belt 10. The two rotating connecting shafts 5 can drive four sets of rotating discs 6 to rotate. The four rotating discs 6 drive multiple sets of universal wheels 8 to rotate through multiple sets of connecting plates 7. When the four intact universal wheels 8 contact the ground, the self-locking motor 11 is stopped. At this time, the sponge plate 19 can be moved by hand to wipe the four universal wheels 8 that previously contacted the ground. After wiping, the magnet plate 20 is adsorbed to the lower part of the mobile rack 1. Through the provided concave plate 4, connecting shafts 5 and rotating discs 6, the universal wheels 8 can be replaced, and at the same time, the impurities adhered to the surface of the universal wheels 8 are prevented from contaminating the clean ground, improving the practicality of the mobile gas chromatograph support. At the same time, when a gas chromatograph needs to be installed, the operator moves the gas chromatograph by hand. When the gas chromatograph contacts multiple sets of suction cups 12, the control panel is used to open and close the multiple solenoid valves below the multiple suction cups 12 contacted by the gas chromatograph. Then, the control panel is used to operate the air extraction pump 14. The air extraction pump 14 can extract the air inside the multiple suction cups 12 and the air storage tank 2 through a set of right connecting pipes 15. A negative pressure environment is formed inside the multiple suction cups 12 and the air storage tank 2, and the gas chromatograph can be adsorbed. When the gas chromatograph is stably fixed, the right set of control valves 16 is closed. When the gas chromatograph needs to be disassembled, the operator opens and closes the left set of control valves 16 by hand, and then the control panel is used to operate the air inflation pump 13. Air can enter the air outlet box and the inside of the multiple suction cups 12 through the left set of connecting pipes 15, and then the gas chromatograph can be removed. Through the provided air storage tank 2, the stable installation of gas chromatographs of various sizes can be adapted, providing guarantee for the stable use of the mobile gas chromatograph support for the gas chromatograph.
