[0023] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0024] Reference Figure 1-6 A gas chromatograph shockproof mechanism includes a protection component 1, two reset components 2 are arranged in the protection component 1, an adjustment component 3 is arranged in the protection component 1, the protection component 1 includes a shell 11, the shell 11 is connected to two baffles 12 respectively through the two reset components 2, the two baffles 12 are arranged on the shell 11, the shell 11 is hinged to the same lifting rod 13 through two pins, by setting the lifting rod 13, when it is necessary to move the structure, the lifting rod 13 is rotated, the lifting rod 13 moves to the top of the baffle 12, the user moves the protection structure through the lifting rod 13, when it is necessary to use the chromatograph body 5, the lifting rod 13 is rotated, the lifting rod 13 rotates around the pin, so that the lifting rod 13 is moved out from the baffle 12.

[0025] The adjustment component 3 is arranged in the shell 11, and the reset component 2 includes a pin rod 21, which is arranged in the shell 11. Both ends of the pin rod 21 are connected to the fixing frame 22, and the fixing frame 22 is connected to the shell 11 through a coil spring 23. The coil spring 23 is sleeved on the outside of the pin rod 21. By setting the coil spring 23, the baffle 12 can return to the initial position under the action of the torsion of the coil spring 23.

[0026] The adjusting component 3 is connected to the pushing component 4, and the adjusting component 3 includes two bearings 31, and the two bearings 31 are both clamped in the outer shell 11. The same threaded rod 32 is arranged in the two bearings 31. By setting the bearings 31, the bearings 31 can limit and fix the threaded rod 32 in the outer shell 11.

[0027] One end of the threaded rod 32 is connected to the turntable 33, and the threaded rod 32 is externally threaded with two movable rods 34. By setting the threaded rod 32 and the movable rod 34, because the threaded rod 32 is composed of two threaded columns with opposite thread directions, the rotating threaded rod 32 can drive the two movable rods 34 to move closer to or away from each other.

[0028] The two movable rods 34 are both overlapped with the outer shell 11, and the two movable rods 34 are respectively hinged to the bottom ends of the four connecting rods 35 through two pins. The four connecting rods 35 are all connected to the same pushing assembly 4 through the pins. By setting the movable rod 34, because the movable rod 34 is overlapped with the outer shell 11, the outer shell 11 can limit the movable rod 34, so that the movable rod 34 will not rotate under the action of the rotating threaded rod 32, so that the movable rod 34 can move smoothly along its axial direction under the action of the rotating threaded rod 32.

[0029] A chromatograph body 5 is provided on the pushing assembly 4, and the pushing assembly 4 includes a connecting plate 41. The connecting plate 41 is hinged to the top ends of four connecting rods 35 through four pins respectively, and the connecting plate 41 is connected to the main body of the chromatograph body 5. Four first push rods 42 and four second push rods 43 are connected to the connecting plate 41. The top ends of the four second push rods 43 are overlapped with the bottom of two baffles 12 respectively, and the height of the second push rod 43 is higher than the height of the first push rod 42. By setting the first push rod 42 and the second push rod 43, because the height of the second push rod 43 is higher than the height of the first push rod 42, when the connecting plate 41 moves, the moving connecting plate 41 can drive the second push rod 43 to push the baffle 12 to move.

[0030] The shape of the connecting plate 41 is set to be rectangular, and the connecting plate 41 is slidably connected in the outer shell 11. By setting the connecting plate 41 and the outer shell 11, since the connecting plate 41 is slidably connected in the outer shell 11, the outer shell 11 can limit the connecting plate 41 so that the connecting plate 41 will not shake during movement, so that the moving connecting plate 41 can drive the chromatograph body 5 to move smoothly.

[0031] A damper 6 is installed at the upper end of the connecting plate 41, and the upper end of the damper 6 is installed at the lower end of the chromatograph body 5. The chromatograph body 5 and the connecting plate 41 are elastically connected by multiple springs. By setting the springs and the damper 6, the damper 6 and the springs can reduce the shock of the chromatograph body 5, thereby providing good buffering for the chromatograph body 5.

[0032] When the utility model is used, the turntable 33 rotates forward, and the rotating turntable 33 drives the threaded rod 32 to rotate in the two bearings 31. Because the threaded rod 32 is composed of two threaded columns with opposite thread directions, the rotating threaded rod 32 can drive the two movable rods 34 to move away from each other. The two movable rods 34 that move away from each other both drive the connecting plate 41 to move upward through the two connecting rods 35. The connecting plate 41 that moves downward pushes the baffle 12 through the four first push rods 42 and the four second push rods 43. The baffle 12 drives the pin rod 21 to rotate in the shell 11, and the four coil springs 23 are twisted. The connecting plate 41 that moves upward drives the chromatograph body 5 to move out of the shell 11. The turntable 33 is reversed, and the connecting plate 41 that moves downward drives the chromatograph body 5 to move into the shell 11. The two baffles 12 are driven to rotate through the pin rod 21 under the action of the torsional force of the coil springs 23 and then contact the shell 11.

[0033] The above description 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.
