A moving sleeve is threadedly sleeved on the circumferential side of the rotating shaft and located below the rectangular block. A connecting plate is fixedly connected to one side of the moving sleeve, and a locking block is welded on the side of the connecting plate away from the moving sleeve. A clamping plate is symmetrically welded on the side of the moving block away from the rectangular block. A vertical rod is passed through the top surface of the two clamping plates, and a clamping block is installed on the circumferential side of the vertical rod. The safety protection device for chemical inspection solves the problem of raw liquid overflowing from the beaker during sampling and causing harm to the staff, thereby improving the safety during the sampling process.

[0003] However, when implementing the above technical solution, there are the following problems: the above technical solution solves the problem of the original liquid overflowing from the beaker during sampling and causing harm to the staff, and improves the safety during the sampling process. However, during the inspection process, in order to achieve the best inspection effect, it is necessary to continuously shake the beaker when adding chemical agents, so that the chemical agents can fully contact the surface of the inspection sample and improve the reaction efficiency of the inspection sample.

[0024] See also Figure 1-5 , this utility model provides two technical solutions:

[0025] Example 1

[0026] A safety protection device for chemical inspection includes an inspection box 1, a dripping mechanism 2 is provided inside the inspection box 1, and an inspection mechanism 3 is provided at the bottom of the inner cavity of the inspection box 1. The inspection mechanism 3 includes:

[0027] The inspection component 31 includes a support plate 311 installed at the bottom of the inner cavity of the inspection box 1. The top of the support plate 311 is rotatably connected to a rotating rod 312. The surface of the rotating rod 312 is fixedly connected to a placement plate 313 through a connecting block. The top of the placement plate 313 is provided with a placement groove for placing the inspection beaker. The inner wall of the placement groove is provided with a limit slide groove. Limit sliders are installed at both ends of the fixed plate 314. The limit sliders slide on the inner surface of the limit slide groove. The interior of the placement plate 313 is controlled by the control component 4 to make the fixed plate 314 slide. The surface of the fixed plate 314 is slidably connected to the inner wall of the placement plate 313.

[0028] The driving assembly 32 is arranged on the top of the support plate 311. The control assembly 4 includes a control rod 41 and a control spring 42 installed on one side of the fixed plate 314. The surface of the control rod 41 is slidably connected to the inside of the placement plate 313. One end of the control spring 42 is fixedly connected to the inner wall of the placement plate 313. The driving assembly 32 includes a driving motor 321 installed on the top of the support plate 311. The driving motor 321 is a three-phase asynchronous motor and is connected to the external circuit through wires. One end of the output shaft of the driving motor 321 is fixedly connected to the driving block 322 through a coupling. One end of the driving block 322 rotates the rotating rod 312 through the transmission assembly 5. One end of the driving block 322 is fixedly connected to the sliding block 323. The transmission assembly 5 includes a transmission plate 51 installed on the surface of the rotating rod 312. The surface of the transmission plate 51 is opened A sliding groove 52 is provided, and the inner surface of the sliding groove 52 is slidably connected to the surface of the sliding block 323. By starting the driving motor 321 to drive the driving block 322 and the sliding block 323 to rotate, the sliding block 323 slides on the inner surface of the sliding groove 52, thereby causing the transmission plate 51 to swing back and forth in a small amplitude. The swinging of the transmission plate 51 causes the rotating rod 312 to rotate, and then the connecting block and the placement plate 313 to swing back and forth synchronously, so that the chemical reagents in the test beaker are fully in contact with the surface of the test sample, thereby improving the inspection efficiency. By providing the inspection mechanism 3, the placement plate 313 is driven by the driving motor 321 to swing back and forth as a whole, thereby causing the test beaker placed therein to swing synchronously, so that the chemical reagents can more fully contact the surface of the test sample, thereby improving the inspection efficiency.

[0029] Example 2

[0030] The main differences from Example 1 are:

[0031] A safety protection device for chemical inspection, the dropping mechanism 2 includes an adjusting motor 21 installed on the left side of the inspection box 1, the adjusting motor 21 is a three-phase asynchronous motor, and is connected to the external circuit through wires, one end of the output shaft of the adjusting motor 21 is fixedly connected to a screw rod 22 through a coupling, the surface of the screw rod 22 is threadedly connected to a moving plate 23, an electric push rod is installed on the top of the moving plate 23, a piston is installed on the output end of the electric push rod, and the piston is arranged inside a dropping tube 24, a dropping tube 24 is installed on the surface of the moving plate 23, and the surface of the dropping tube 24 is fixedly connected to a liquid storage tank 25 through a hose, a one-way valve is provided at the connection between the hose and the liquid storage tank 25, the bottom of the liquid storage tank 25 is fixedly connected to the top of the inspection box 1, the inspection box 1 is fixedly connected to the inner wall of the test box 1 with a positioning rod 6, and the surface of the positioning rod 6 is slidably connected to the inside of the movable plate 23. A fan 7 is installed on the right side of the top of the test box 1, and an air duct is installed at one end of the fan 7. The air duct is connected to the external gas treatment device. By providing a dripping mechanism 2, the position of the dripping tube 24 is automatically adjusted under the drive of the adjustment motor 21 to realize the automatic dripping operation of the chemical agent, and the toxic gas generated during the inspection process is discharged by providing the fan 7. Since the staff operates outside the test box 1 throughout the process, it can avoid chemical hazards to the staff, thereby improving the safety of the staff's inspection. At the same time, the contents not described in detail in this specification belong to the existing technology well known to those skilled in the art.

[0032] During operation, by pulling the control rods 41 on both sides, the fixed plates 314 on both sides are driven to slide synchronously to the opposite sides, so that the control spring 42 is compressed, and the fixed plate 314 slides on the inner wall of the placement plate 313, and the inspection beaker is fixed by the fixed plate 314, and the sample to be inspected is placed in the inspection beaker. Subsequently, by starting the adjustment motor 21 to drive the screw rod 22 to rotate, the rotation of the screw rod 22 causes the movable plate 23 to slide, and the movable plate 23 slides on the surface of the positioning rod 6. The sliding of the movable plate 23 drives the dripping tube 24 to move synchronously, so that the dripping tube 24 slides to the top of the inspection beaker. Subsequently, by starting the electric push rod installed on the top of the movable plate 23, the piston is pushed to slide inside the dripping tube 24, and the liquid in the storage tank 25 is discharged through the hose. The chemical reagent is introduced into the drip tube 24 and dripped onto the test sample through the drip tube 24. Subsequently, the driving motor 321 is started to drive the driving block 322 and the sliding block 323 to rotate, so that the sliding block 323 slides on the inner surface of the sliding groove 52, thereby causing the transmission plate 51 to swing back and forth in a small range. The swing of the transmission plate 51 causes the rotating rod 312 to rotate, and then the connecting block and the placement plate 313 to swing back and forth synchronously, so that the chemical reagent in the test beaker is fully in contact with the surface of the test sample, thereby improving the test efficiency. Finally, during the test process, the fan 7 is started and the air duct is used to extract the gas generated during the test process and guide it to the external treatment device to avoid the leakage of harmful gases and cause damage to the staff.
