For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. The following describes the embodiments of the present invention based on its overall structure.

[0025] Reference Figures 1 to 7 In an embodiment of the utility model, a fluoroethylene carbonate sampling device includes: a box body 1, an infusion tube 2 is installed at one end of the top of the box body 1, a glove body 3 is symmetrically installed on the narrower two side walls inside the box body 1, a first telescopic rod 4 is installed at the center position of the inner bottom of the box body 1, a circular plate 5 is installed on the top of the first telescopic rod 4, a movable plate 6 is installed on the top of the circular plate 5, and several groups of placement racks 7 are installed at equal intervals at the top edge of the movable plate 6, and sampling bottles 8 are arranged inside the placement racks 7.

[0026] Reference Figures 1 to 5 A support plate 9 is installed at the inner bottom of the box body 1 near the first telescopic rod 4, and a threaded rod 10 is installed on the outer side surface of the support plate 9. One end of the threaded rod 10 passes through the box body 1 and extends to the outside thereof, and a turning handle 11 is installed at one end of the threaded rod 10 located outside the box body 1. The outer ring surface of the threaded rod 10 is threadedly connected to the box body 1, and one end of the threaded rod 10 is rotatably connected to the outer side surface of the support plate 9.

[0027] The above solution is adopted: the threaded rod 10 is driven to rotate by rotating the turning handle 11, thereby driving the support plate 9 to move on the inner bottom of the box body 1.

[0028] Reference Figures 1 to 5 The supporting plate 9 is symmetrically installed with connecting plates 12 at both ends of the side surface away from the threaded rod 10. The bottoms of the supporting plate 9 and the two connecting plates 12 are slidably connected to the inner bottom of the box body 1. A limiting groove 1201 is provided on the outer surface of the connecting plate 12, and the limiting groove 1201 is set to an inclined shape.

[0029] With the above solution, the support plate 9 moves inside the box body 1 and synchronously drives the two connecting plates 12 to move, so that the two limiting grooves 1201 move synchronously toward one end.

[0030] Reference Figures 1 to 5 The bottom of the circular plate 5 and the two sides of the first telescopic rod 4 are symmetrically installed with fixed blocks 13, and the outer side of the fixed block 13 and the inner side of the corresponding limiting groove 1201 are both installed with cylindrical blocks 14.

[0031] The above scheme is adopted: the two connecting plates 12 move and extrude the cylindrical block 14 to slide inside the limiting groove 1201, driving the fixed block 13 to rise, thereby driving the circular plate 5 to rise and the first telescopic rod 4 to extend synchronously. By setting the first telescopic rod 4, the stability of the circular plate 5 in lifting and lowering is increased. By adjusting the height of the circular plate 5, it is convenient to bring the bottle mouth of the sampling bottle 8 close to the liquid outlet pipe of the infusion tube 2, so as to facilitate sampling.

[0032] Reference Figures 1 to 5 Fixed arc plates 15 are symmetrically installed at both ends of the top of the support plate 9, the outer ring surface of the movable plate 6 is slidingly connected to the inner side walls of the two fixed arc plates 15, and the bottom of the movable plate 6 is rotatably connected to the top of the circular plate 5, and handles 16 are symmetrically installed at both ends of the top of the movable plate 6.

[0033] The above scheme is adopted: when the sampling of one of the sampling bottles 8 is completed, the handle 16 is grasped by both hands to drive the movable plate 6 to rotate on the top of the circular plate 5, so that the next sampling bottle 8 is rotated to the bottom of the infusion tube 2. This cycle is convenient for multiple sampling and the operation is convenient. After all the sampling is completed, the sealing cover of the sampling bottle 8 is covered and the box door can be opened. The movable plate 6 can be taken out through the two handles 16, which is convenient for sampling. There is no need for the staff to take the sampling bottles one by one for sampling, which avoids the situation that it is easy to spill during the taking process.

[0034] Reference Figures 6 and 7 A second telescopic rod 17 is symmetrically installed at both ends of the inner wall of the placement rack 7, a return spring 18 is installed on the outer ring surface of the second telescopic rod 17, and a limiting arc plate 19 is installed at one end of the second telescopic rod 17, and the top end of the limiting arc plate 19 is set to a funnel shape.

[0035] The above scheme is adopted: the sampling bottle 8 is inserted between the two limiting arc plates 19, and the top end of the two limiting arc plates 19 is set to a funnel shape to facilitate the insertion of the sampling bottle 8. The sampling bottle 8 will squeeze the two limiting arc plates 19 away and compress the second telescopic rod 17 and the return spring 18, thereby limiting and fixing the sampling bottle 8 inside the placement rack 7, thereby facilitating the limiting of sampling bottles of different sizes, and having wider practicality.

[0036] The working principle of the present invention is as follows: in the process of sampling fluoroethylene carbonate, the threaded rod 10 is driven to rotate by rotating the handle 11, thereby driving the support plate 9 to move at the inner bottom of the box body 1, and the support plate 9 moves inside the box body 1 and synchronously drives the two connecting plates 12 to move, so that the two limiting grooves 1201 move synchronously to one end, and the two connecting plates 12 move to squeeze the cylindrical block 14 to slide inside the limiting groove 1201 and drive the fixed block 13 to rise, thereby driving the circular plate 5 to rise and the first telescopic rod 4 to extend synchronously. The stability of the circular plate 5 in lifting and lowering is increased by setting the first telescopic rod 4. By adjusting the height of the circular plate 5, it is convenient to bring the bottle mouth of the sampling bottle 8 close to the liquid outlet pipe of the infusion tube 2 for easy sampling. By inserting both hands into the inside of the glove body 3, operation can be performed inside the box 1. When sampling of one of the sampling bottles 8 is completed The sampling bottle 8 will squeeze the two limiting arc plates 19 away and compress the second telescopic rod 17 and the return spring 18, so that the sampling bottle 8 is limited and fixed inside the placement rack 7, which is convenient for limiting sampling bottles of different sizes and has wider practicality.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
