[0012] In a possible design, the lifting mechanism includes four sliding columns, two threaded columns, two No. 2 rotating handles and multiple connecting blocks, the two threaded columns and the four sliding columns have two ends rotatably connected to the bottom inner wall and the top inner wall of the multiple rectangular grooves respectively, the two No. 2 rotating handles are fixedly connected to the bottom with a No. 2 rotating column, one end of the two No. 2 rotating columns respectively penetrates the top of the side plate and is fixedly connected to one end of the threaded column, the two No. 2 rotating columns are respectively rotatably connected to the two side plates, the multiple connecting blocks are respectively threadedly sleeved on the two threaded columns and slidably sleeved on the four sliding columns, and one side of the multiple connecting blocks is respectively fixedly connected to the side close to the two lifting plates.

[0013] In a possible design, the shielding mechanism includes a No. 1 frame, a No. 1 shielding plate, a No. 2 frame, a No. 2 shielding plate and two baffles. The rear sides of the No. 1 frame and the No. 2 frame are fixedly connected to the front side of the same liquid chromatograph body. The No. 1 sliding groove and the No. 2 sliding groove are respectively provided on the inner walls of the No. 1 frame and the No. 2 frame.

[0016] In the present application, when in use, by rotating the No. 1 rotating handle, the No. 1 rotating column and the threaded rod fixedly connected thereto are driven to rotate. Since the threaded rod and the moving block are threadedly connected, the rotation of the threaded rod will drive the moving block to move along the threaded rod.

When the display screen needs to be shielded, the push plate pushes the No. 1 shielding plate and the No. 2 shielding plate toward the display screen until they completely cover the display screen; when the display screen needs to be observed, the push plate only needs to be pushed in the opposite direction to move the No. 1 shielding plate and the No. 2 shielding plate away.

The design of the placement frame allows the staff to easily place the reagent bottle on the top of the liquid chromatograph body to prevent the reagent bottle from falling. The setting of the fixing plate and the fixing hole provides further fixation of the liquid chromatograph body. The possibility of separation is enhanced, and the stability and safety of the device are enhanced. When testing artificial leather, the sample is introduced from a syringe into a liquid chromatography column through a mobile phase. The sample molecules are separated in the column by the flow of the mobile phase and the action of the stationary phase. The sample is separated by a liquid chromatography column filled with an adsorbent. According to the different hydrophilicity and hydrophobicity of the sample components, the retention time of different components in the column is also different. The separated compounds enter the mass spectrometry part, and the compound analysis is performed using the ion mass. The sample molecules are ionized to generate ions. After tandem mass spectrometry analysis, the structure of the compound can be accurately identified based on the mass-to-charge ratio spectrum of the ions, and then the test results are displayed on the display screen.

At the same time, the stability and safety of the device are further enhanced through the design of the placement frame and the fixing plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Embodiment 1

[0026] Reference Figure 1-Figure 4 , a detection device, comprising a liquid chromatograph body 1:

[0027] The liquid chromatograph body 1 is used to detect the content of various additives in artificial leather. Two display screens are set on the front side of the liquid chromatograph body 1 to display different detection data for the convenience of staff observation. In addition, multiple control buttons are also provided to facilitate staff to operate the liquid chromatograph body 1.

[0028] Two side plates 12 are fixedly connected to both sides of the liquid chromatograph body 1 . Three rectangular grooves are arranged on one side of the side plates 12 away from the liquid chromatograph body 1 . These rectangular grooves are used for installing and moving components in the subsequent lifting mechanism.

[0029] The moving mechanism is for facilitating the movement and fixation of the liquid chromatograph body 1, and mainly comprises two L-shaped plates 3, two No. 1 rotating handles 6, two moving blocks 7, two threaded rods 8, two lifting plates 9 and four slide grooves 10, wherein the bottom sides of the L-shaped plate 3 are fixed with sliders adapted to the slide grooves 10, the sliders can slide in the slide grooves 10, and the slide grooves 10 are arranged on the top sides of the lifting plate 9, so that the L-shaped plate 3 can be connected to the lifting plate 9 by sliding the sliders in the slide grooves 10, and the moving blocks 7 can be connected to the lifting plate 9 by sliding the sliders in the slide grooves 10. The threaded sleeve is arranged on the threaded rod 8. When the No. 1 rotating handle 6 is rotated, the No. 1 rotating handle 6 drives the threaded rod 8 to rotate, thereby driving the moving block 7 to move along the threaded rod 8. Since the moving block 7 is fixedly connected to the L-shaped plate 3, the L-shaped plate 3 will also move accordingly. In this way, when the liquid chromatograph body 1 needs to be fixed, it is only necessary to rotate the No. 1 rotating handle 6 to drive the L-shaped plate 3 to move. The L-shaped plate 3 is stuck with both sides of the table body, and then the liquid chromatograph body 1 is fixed on the table body to prevent the liquid chromatograph body 1 from being damaged.

[0030] The lifting mechanism is designed to facilitate the height adjustment of the liquid chromatograph body 1. It mainly includes four sliding columns 13, two threaded columns 15, two No. 2 rotating handles 14 and multiple connecting blocks 11. The threaded columns 15 and the sliding columns 13 are all installed in the rectangular grooves and can rotate with the rectangular grooves. The connecting blocks 11 are respectively threadedly sleeved on the threaded columns 15 and slidably sleeved on the sliding columns 13. When the No. 2 rotating handle 14 is rotated, the No. 2 rotating handle 14 drives the threaded column 15 to rotate, thereby driving the connecting block 11 to move up and down along the threaded column 15. Since the connecting block 11 is fixedly connected to the lifting plate 9, the lifting plate 9 will also move up and down accordingly. In this way, when the liquid chromatograph body 1 needs to be fixed, it is only necessary to rotate the No. 2 rotating handle 14 to drive the L-shaped plate 3 to be lifted and lowered through the lifting plate 9, and then the L-shaped plate 3 is fixed to the two sides of the table body through the special shape of the L-shaped plate 3, thereby fixing the liquid chromatograph body 1.

[0031] The shielding mechanism is used to shield the display screen to prevent it from being damaged. It mainly includes a frame No. 16, a shielding plate No. 17, a frame No. 2 19, a shielding plate No. 2 20 and two baffles 21. The rear sides of the frame No. 16 and the frame No. 2 19 are fixedly connected to the front side of the liquid chromatograph body 1. The shielding plate No. 17 and the shielding plate No. 20 can slide on the inner walls of the frame No. 16 and the frame No. 2 19 respectively. The baffle 21 is arranged on the rear sides of the shielding plate No. 17 and the shielding plate No. 20 to increase the shielding effect. When it is necessary to shield the display screen, it is only necessary to push the push plate 18 to drive the shielding plate No. 17 and the shielding plate No. 20 to move and shield the display screen.

[0032] The present application can be used in the field of additive content detection, and can also be used in other fields applicable to the present application.
