[0027] The specific implementation method is as follows: by providing a locking mechanism 5, the solvent bottle 4 can be automatically clamped and fixed after being placed, thereby greatly improving the stability of the solvent bottle 4 during use and facilitating its disassembly later.

[0028] As attached Figure 1 、 Figure 2 With attached Figure 5 The fully automatic gasoline chromatograph analyzer shown in the figure has a buffer mechanism 6 including a drive chamber 18 opened on the top surface of the base 2, the lower end side wall of the gasoline chromatograph analyzer body 1 is slidingly connected to the inner side wall of the drive chamber 18, an airbag 19 is installed on the inner bottom surface of the drive chamber 18, the top surface of the airbag 19 is in contact with the bottom surface of the gasoline chromatograph analyzer body 1, an air pump 20 is installed at one end of the top surface of the base 2, and the output end of the air pump 20 is connected to the airbag 19, so that the airbag 19 can easily buffer the bumps experienced by the gasoline chromatograph analyzer body 1.

[0029] The sliding groove 21 is opened on one side of the driving compartment 18, and the sliding block 22 is slidably connected to the sliding groove 21. One end of the sliding block 22 is fixedly connected to the side wall of the gasoline chromatograph analyzer body 1.

[0030] The specific implementation method is as follows: a buffer mechanism 6 is provided to buffer the gasoline chromatograph main body 1 when the device moves, thereby preventing the gasoline chromatograph main body 1 from being damaged by bumps during movement.

[0031] The working principle of the utility model is as follows: during operation, when placing the solvent bottle 4, first place the solvent bottle 4 on the surface of the placing plate 8. After being subjected to force, the placing plate 8 will drop and press the No. 1 switch 13. The corresponding cylinder 10 is activated by the No. 1 switch 13 to extend, and the cylinder 10 drives the V-shaped clamping block 11 to approach the solvent bottle 4, clamping and fixing the solvent bottle 4, greatly improving the stability of the solvent bottle 4. Then, the solvent bottle 4 is connected to the gasoline chromatograph analyzer body 1 through a conduit, and the chromatographic analysis of gasoline can be automatically performed. When the solvent bottle 4 needs to be disassembled or replaced, first press the pressing block 15 to drive the driving plate 12 to drop, so that the driving plate 12 drives multiple No. 1 switches 13 to drop until the top surface of the No. 1 switch 13 is no longer in contact with the bottom surface of the solvent bottle 4. At this time, the cylinder 10 drives the V-shaped clamping block 11 to contract, releasing the fixation of the solvent bottle 4, and then the solvent bottle 4 can be replaced or disassembled. Unloading, the guide wheel 17 is used to facilitate the movement of the device. When it is bumpy during movement, the air bag 19 is used to cushion the bumps suffered by the gasoline chromatograph analyzer main body 1, thereby greatly improving the safety of the gasoline chromatograph analyzer main body 1 and preventing it from being damaged by bumps. When the air pressure in the air bag 19 becomes lower and lower with the passage of time, the sliding block 22 will gradually move downward until it presses the No. 2 switch 24. At this time, the No. 2 switch 24 starts the air pump 20 to work for a specified time to inflate the air bag 19, so that the air pressure in the air bag 19 is always maintained within the specified range, thereby greatly improving the buffering stability of the gasoline chromatograph analyzer main body 1. When the gasoline chromatograph analyzer main body 1 does not need to be moved, the screw 30 is rotated to cause the drive block 29 to drive the U-shaped pressure plate 25 to descend until the anti-slip pad 27 on the bottom surface of the U-shaped pressure plate 25 contacts the ground, thereby greatly improving the stability of the device.
