[0017] like Figure 1 and Figure 2 As shown, the present invention provides a protective device for laboratory experiments, including a shell 1, the shell 1 includes a bottom plate 1.1, a curved plate 1.2 is vertically connected to one side of the bottom plate 1.1, a top plate 1.3 is connected to the upper side of the curved plate 1.2, and a curved strip 1.4 is connected to one side of the curved plate 1.2.

[0018] An arc-shaped receiving groove is provided on the side of the arc-shaped plate 1.2, and a second protective cover 1.5 is received in the arc-shaped receiving groove. The second protective cover 1.5 is made of tempered glass. An arc-shaped guide groove 1.6 is provided on the upper side of the arc-shaped strip 1.4. The second protective cover 1.5 is guided by the arc-shaped guide groove 1.6. A handle is connected to the second protective cover 1.5. The second protective cover 1.5 is pulled by the handle, which can not only provide simple protection for the safety laboratory 6 below, but also provide secondary protection for the dangerous laboratory 5.

[0019] A motor 2 is connected to the bottom plate 1.1, and a rotating plate 3 is connected to the upper side of the output shaft of the motor 2. The rotating plate 3 is a circular plate. The rotating plate 3 separates the shell 1 into a laboratory and an installation cavity. A partition 4 is connected to the rotating plate 3. The partition 4 is vertically arranged. The partition 4 separates the laboratory 3 into a dangerous laboratory 5 and an ordinary laboratory 6.

[0020] Two first electrical connectors 10 are connected to the lower side of the partition 4, and each first electrical connector 10 is electrically connected to a power strip 11. The two power strips 11 are respectively connected to the hazardous laboratory 5 and the ordinary laboratory 6, so as to supply power to the equipment in the laboratory. A second electrical connector 12 is connected to the top of the shell 1 through a group of support rods, and the second electrical connector 12 is arranged in conjunction with the first electrical connector 10.

[0021] like Figure 3 As shown, the first electrical connector 10 includes a fixing plate 101 , a mounting groove is provided on the lower side of the fixing plate 101 , a first conductive sheet 102 is connected in the mounting groove, and the first conductive sheet 102 is connected to the corresponding power strip 11 through a first wire.

[0022] The second electrical connector 12 includes a receiving plate 121, which is an arc-shaped structure. A guide groove of a corresponding shape is provided on the upper side of the receiving plate 121. A second conductive piece 122 of a corresponding shape is connected in the guide groove. The cross-section of the second conductive piece 122 is U-shaped. The first conductive piece 102 is inserted and slid in the second conductive piece 122. The second conductive piece 122 is connected to the power supply through a second wire. The rotation of the motor 2 can drive the two first conductive pieces 102 to rotate, so that the first conductive piece 102 enters the second conductive piece 122, so that electricity is passed between the first conductive piece 102 and the second conductive piece 122. This can prevent the wires from getting entangled when the motor 2 drives the rotating plate 5 to rotate, so that the dangerous laboratory 5 and the safe laboratory 6 can be powered on as soon as possible when switching.

[0023] A first protective cover 7 is connected to the opening of the hazardous laboratory 5. The first protective cover 7 is made of tempered glass and seals the hazardous laboratory 5. Two operating ports 8 are provided on the first protective cover 7. An isolation operating member 9 is connected to the inner side of each operating port 8.

[0024] like Figure 4 As shown, the isolation operating member 9 includes a mounting plate 9.1, which is connected to the operating port 8. A mounting hole 9.2 is provided on the mounting plate 9.1. A protective glove 9.3 is connected to the inner side of the mounting hole 9.2. The protective glove 9.3 has a double-layer material, the outer layer is an anti-corrosion material, and the inner layer is a sealing material, which can protect the arm and ensure air tightness to prevent toxic gas from escaping. When it is necessary to operate the equipment in the dangerous laboratory 5, the hand is passed through the mounting hole 9.2, the hand is wearing the protective glove 9.3, and then the equipment is operated, thereby further improving safety.

[0025] A medicine passage 5.1 is provided at the bottom of the hazardous laboratory 5. A driving member 13 is connected to the bottom of the shell 1. A tray 14 is connected to the driving rod of the driving member 13. The tray 14 is inserted upward into the medicine passage 5.1. When conducting a hazardous experiment, the device first places the medicine to be used into the tray 14. Then, the motor 2 is used to drive the hazardous laboratory 5 to rotate in front of the operator. Then, the driving member 13 is started to drive the tray 14 to move upward so that the tray 14 seals the medicine passage 5.1. The tray 14 can not only position the rotating plate 3 but also provide medicine to the sealed hazardous laboratory 5.

[0026] This device can control the rotation of the rotating plate 3 by the motor 2 according to the danger of the experiment, thereby switching the safe laboratory 6 and the dangerous laboratory 5. When conducting a safe experiment, the motor 2 drives the safe laboratory 6 to rotate in front of the operator. When conducting a dangerous experiment, the medicine to be used is first placed in the tray 14, and the motor 2 drives the dangerous laboratory 5 to rotate in front of the operator, and then the medicine is sent into the dangerous laboratory 5. When it is necessary to operate the equipment in the dangerous laboratory 5, the protective gloves 9.3 are worn on the hands to operate, which can prevent dangerous liquids from splashing on the arms and prevent toxic gases from escaping.
