However, in the process of use, the prior art is generally provided with a box body, a mechanism for realizing chromatographic analysis is installed in the box body, and a heat dissipation structure is further arranged on the box body. The defect of the existing heat dissipation structure is that the angle of the heat dissipation blade cannot be changed, and the heat dissipation area cannot be closed to block the heat dissipation holes when not in use, so as to prevent sundries from entering the interior of the equipment. For this reason, people have made a lot of research. CONTENT OF THE UTILITY MODEL

[0003] The utility model solves the technical problem that the chemical reagent chromatographic analysis appearance can solve the problem in the prior art.

[0004] The utility model is realized through the following technical schemes: the utility model relates to a chemical reagent chromatographic analysis appearance, which comprises a chromatographic analysis appearance, and a heat dissipation structure is arranged on one side of the chromatographic analysis appearance, characterized in that the heat dissipation structure comprises a mounting plate, heat dissipation holes are arranged in the mounting plate, left and right inner cavities are arranged at the rear side of the heat dissipation holes, a plurality of heat dissipation plate assemblies distributed in an up-down mode are hingedly arranged between the inner cavities, and a control assembly for simultaneously controlling and turning over the heat dissipation plate assemblies is arranged in the mounting plate.

[0005] Further technical schemes are that the heat dissipation plate assembly comprises a first turning plate, the first turning plate is hingedly arranged with the mounting seats on the left and right sides, an inner cavity is arranged in the first turning plate, a second turning plate is slidably arranged in the inner cavity, and an elastic structure is elastically arranged between the second turning plate and the upper end wall of the inner cavity.

[0006] Further technical schemes are that the elastic structure comprises a plurality of springs arranged on one side of the second turning plate, and the springs are connected to the top of the inner cavity.

[0007] Further technical schemes are that the control assembly comprises one guide rod arranged on the rear side of the mounting plate, one moving frame is slidably arranged on the outer side of the guide rod, a connecting rod structure is arranged between the moving frame and the first turning plate, and a moving structure for moving the moving frame forward and backward is arranged in the mounting plate.

[0008] A further technical solution includes a linkage structure comprising a slide groove disposed within the movable frame, a side rod disposed on one side of the first flap, a stop rod disposed on one side of the side rod, the stop rod extending into the slide groove, and the slide groove slidingly abutting against the end wall of the slide groove.

[0009] A further technical solution includes a movable structure comprising an internally threaded sleeve disposed within the mounting plate, the internally threaded sleeve being internally threadedly connected to a handle threaded shaft, a mounting ring being disposed within the movable frame, and a rotating block being disposed on one side of the handle threaded shaft, the rotating block being rotatably disposed within the mounting ring.

[0010] In a further technical solution, a connecting block is provided on one side of the mounting ring.

[0011] The beneficial effects of this utility model are: First, by simultaneously driving the first flap to rotate, the second flap can extend out from the inner cavity, so that the first flap and the second flap on the upper and lower sides abut against each other, thereby closing one side of the mounting plate and thus achieving the function of isolating debris; and the first flap can be rotated and adjusted at the same time to adjust the angle of the first flap in multiple positions to change the size of the heat dissipation area.

[0012] Second, the purpose of setting the second flap and the inner cavity to be elastically slidingly connected is that the second flap is inserted into the first flap by abutting against the rear end wall of the heat dissipation hole.

Detailed Implementation

[0026] like Figures 1-10 As shown, this utility model will be described in detail. For ease of description, the directions mentioned below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1 The projection relationship of the instrument is consistent in the up, down, left, right, front and back directions. The chemical reagent chromatography analyzer of this utility model includes a chromatography analyzer 11. A heat dissipation structure is provided on one side of the chromatography analyzer 11. The heat dissipation structure includes a mounting plate 51. A heat dissipation hole 13 is provided in the mounting plate 51. A cavity 32 is provided on the left and right sides behind the heat dissipation hole 13. Multiple heat dissipation plate assemblies are hinged between the cavities 32 and distributed vertically. An operating component is provided in the mounting plate 51 to simultaneously control and rotate all the heat dissipation plate assemblies.

[0027] Advantageously, the heat sink assembly includes a first flap 31, which is hinged to the mounting seats 22 on both sides. The first flap 31 has an inner cavity 32, and a second flap 33 is slidably disposed in the inner cavity 32. An elastic structure is elastically disposed between the second flap 33 and the upper wall of the inner cavity 32. When the first flap 31 rotates toward the heat sink 13, the end of the second flap 33 abuts against the rear end face of the heat sink 13 to retract into the inner cavity 32. After the first flap 31 swings away from the heat sink 13, the second flap 33 extends out of the inner cavity 32. When the second flap 33 abuts against the first flap 31 in the lower heat sink assembly, it can block the heat sink 13 over a large area to prevent debris from entering.

[0028] Advantageously, the elastic structure includes a plurality of springs 34 disposed on one side of the second flap 33, the springs 34 being connected to the top of the inner cavity 32.

[0029] Advantageously, the control component includes an upper and a lower guide rod 27 disposed on the rear side of the mounting plate 51. A movable frame 21 is slidably disposed on the outer side of the guide rod 27. A linkage structure is provided between the movable frame 21 and the first flip plate 31 so that the movable frame 21 moves and drives the first flip plate 31 to rotate. A movable structure is provided inside the mounting plate 51 to move the movable frame 21 back and forth.

[0030] Advantageously, the linkage structure includes a slide groove 25 disposed in the movable frame 21, a side rod 24 disposed on one side of the first flap 31, and an abutting rod 26 disposed on one side of the side rod 24. The abutting rod 26 extends into the slide groove 25, and the slide groove 25 slides against the end wall of the slide groove 25. By moving the movable frame 21 back and forth, the abutting rod 26 can slide in the slide groove 25, thereby causing the side rod 24 to drive the first flap 31 to rotate.

[0031] Advantageously, the movable structure includes an internally threaded sleeve 15 disposed in the mounting plate 51, the internally threaded sleeve 15 is internally threadedly connected to a handle threaded shaft 16, the movable frame 21 is provided with a mounting ring 18, and a rotating block 19 is provided on one side of the handle threaded shaft 16, the rotating block 19 being rotatably disposed in the mounting ring 18.

[0032] Advantageously, a connecting block 17 is provided on one side of the mounting ring 18, which confines the rotating block 19 within the mounting ring 18.

[0033] After rotating the handle threaded shaft 16, the handle threaded shaft 16 is connected to the internal threaded sleeve 15 by thread engagement, and the rotating block 19 rotates in the mounting ring 18, so that the moving frame 21 slides along the handle threaded shaft 16. Since the abutting rod 26 abuts against the slide groove 25, the first flip plate 31 can be flipped by the side rod 24.

[0034] After the first flap 31 rotates, it will also drive the second flap 33 to rotate. During this process, the gap of the heat sink assembly can be changed to improve the heat dissipation effect.

[0035] After the first flap 31 swings to fully extend the second flap 33 from the inner cavity 32, the second flap 33 on the upper and lower sides abut against the first flap 31 to block one side of the heat dissipation hole 13, so as to prevent debris from entering the equipment.
