DETAILED DESCRIPTION

[0022] See also Figures 1 to 5 In an embodiment of the utility model, a gas chromatography touch screen angle adjustment device includes a chromatograph body 1, a touch screen 2 is arranged at the front end of the chromatograph body 1, the touch screen 2 can operate the chromatograph body 1, so that the chromatograph body 1 can work normally, and four support columns 18 are fixedly connected to the lower end of the chromatograph body 1, which not only form a good supporting and fixing effect on the chromatograph body 1, but also increase the contact area between the chromatograph body 1 and the air, so that the chromatograph body 1 has a good heat dissipation function.

[0023] A guide groove is provided inside the chromatograph body 1, and a guide column 4 is embedded in the guide groove. The guide column 4 can ensure the stability of the touch screen 2 when it moves. A limit ring 3 is embedded in the chromatograph body 1, and the front end of the guide column 4 is fixedly connected to the inner column 5. The limit ring 3 is sleeved on the inner column 5. Six first clamping strips 6 are fixedly connected to the outer wall of the inner column 5, and six second clamping strips 8 are fixedly connected to the inner wall of the limit ring 3. The first clamping strips 6 and the second clamping strips 8 are staggered and engaged, and the inner column 5 is rotated inside the limit ring 3 to achieve horizontal adjustment of the touch screen 2.

[0024] The first clamping strip 6 is fixedly connected with a first magnet 7 , and the second clamping strip 8 is fixedly connected with a second magnet 9 . The first magnet 7 and the second magnet 9 are used to fix the limit ring 3 and the inner column 5 by magnetic attraction.

[0025] The front end of the inner column 5 is fixedly connected to a connecting column 10 with a ball groove, a ball 11 is placed inside the ball groove, and the ball 11 is connected to the touch screen 2 through a rotating rod 12. The touch screen 2 can be adjusted at multiple angles by rotating the ball 11 inside the ball groove.

[0026] A clamping ring 13 is sleeved on the connecting column 10, and the clamping ring 13 is used to clamp the opening of the connecting column 10 to prevent the ball 11 from moving out of the ball groove. Spring columns 17 are embedded at both ends of the clamping ring 13. The left end of the spring column 17 is fixedly connected to the fixed plate 14, and the right end of the spring column 17 is fixedly connected to the movable plate 15. A pulling column 16 is fixedly connected to the movable plate 15. The two ends of the clamping ring 13 are clamped by the fixed plate 14 and the movable plate 15 to fix the clamping ring 13.

[0027] The working principle of the utility model is as follows: when the touch screen 2 on the chromatograph body 1 needs to be adjusted horizontally, the touch screen 2 can be directly pulled forward, and the touch screen 2 will drive the inner column 5 to move forward through the rotating mechanism. At this time, the guide column 4 slides inside the guide groove to ensure stability while also playing a fixing role. When the inner column 5 moves, it will drive the first clamping strip 6 to move forward. When the first clamping strip 6 is completely moved out of the limit ring 3, it will no longer contact the second clamping strip 8. At this time, the touch screen 2 can be directly rotated to achieve horizontal angle adjustment. When the touch screen 2 is rotated to an appropriate angle, the touch screen 2 is pushed to re-engage the first clamping strip 6 and the second clamping strip 8 to fix them. The first magnet 7 and the second magnet 9 can be used to fix the touch screen 2. When the touch screen 2 needs to be adjusted at multiple angles, it is only necessary to pull the pull column 16. When the pull column 16 moves, it will drive the movable plate 15 to move. When the movable plate 15 moves, on the one hand, it will gradually separate from the clamping ring 13, and on the other hand, it will pull the spring column 17. At this time, the clamping ring 13 is in a relaxed state, and the touch screen 2 can be arbitrarily rotated and adjusted in the ball groove by the ball 11 to achieve multi-angle adjustment of the touch screen 2. After the adjustment is completed, the pull column 16 is released. Under the action of the spring column 17, the movable plate 15 returns to its original position, and the clamping ring 13 is clamped again to fix the position of the touch screen 2.

[0028] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
