[0016] The present invention provides a safety detection device for hazardous chemicals. It has the following beneficial effects:

[0017] (1) The present invention comprises a housing, a Geiger counter, a slot plate, a short column, an electric telescopic rod, a cabinet door, a slide bar, a slot bar, a U-shaped guide rail, a slide, a test tube rack, a triangular rack and a T-shaped plate in combination with a cylinder. The telescopic end of the electric telescopic rod drives the cabinet door to move backward, and the cabinet door drives the slot bar to move backward. The short column limits the slot bar to reduce the shaking of the cabinet door when it is closed. In the process of moving backward, the triangular rack contacts the cylinder.

The L-shaped orifice plate drives the spring to move upward, and the spring is stretched by the L-shaped orifice plate. Under the elastic force of the spring, the vibration of the test tube rack when it moves upward is reduced, so that the test tube plug in the test tube rack will not vibrate out of the test tube mouth, thereby preventing the test tube plug from vibrating out of the test tube mouth and causing the test tube to leak dangerous chemicals.

[0019] (3) The present invention sets a leak-proof device so that the U-shaped plate, the sliding column and the U-shaped groove frame cooperate with the rubber block, the telescopic end of the electric telescopic rod is reset, and the sliding column moves downward in the sliding groove of the U-shaped groove frame. The sliding column contacts the rubber block during the downward movement. The sliding groove of the U-shaped groove frame limits the sliding column, and the rubber block cushions the bottom of the sliding column, so that the triangular frame will not hit the U-shaped guide rail, thereby preventing the triangular frame from hitting the U-shaped guide rail and causing vibration damage to the test tubes in the test tube rack.

[0020] (4) The present invention arranges the adsorption device so that the long rod, the tube block, the inclined plate and the groove frame cooperate with the activated carbon plate. The inclined plate drives the groove frame to move upward, and the groove frame drives the activated carbon plate to move upward. The activated carbon plate adsorbs the harmful gas in the casing, and the harmful gas in the casing leaks in large quantities, causing personal injury.

[0021] (5) The present invention sets up an adsorption device so that the U-shaped frame, the thin shaft and the long plate cooperate with the arc-shaped spring piece. The U-shaped frame drives the thin shaft to move upward, and the thin shaft drives the long plate to move upward. During the upward movement of the long plate, the long plate blocks the activated carbon plate from sliding out, preventing the activated carbon plate from sliding out of the groove frame and causing damage to the activated carbon plate. The long plate is rotated and a new activated carbon plate is slid into the groove frame. Under the elastic force of the arc-shaped spring piece, the long plate is reset in the U-shaped frame, preventing the inconvenience of replacing the activated carbon plate from causing cumbersome equipment maintenance.

[0036] A leak-proof device 15 is provided at the bottom end of the triangle frame 12 for reducing the vibration of the test tubes containing hazardous chemicals. An adsorption device 16 is provided on the inner wall of the leak-proof device 15 for adsorbing gas leaked from the test tubes of hazardous chemicals.

[0039] See also Figures 1-9 On the basis of the above embodiment, in another embodiment of the present invention, the leakage prevention device 15 includes an L-shaped orifice plate 151, which is respectively fixed to the inner bottom end of the triangular frame 12, and a U-shaped long frame 152 is fixed to the back of the cabinet door 6. The U-shaped long frame 152 is respectively located on the left and right sides of the triangular frame 12, and round rods 153 are respectively fixed to the inner walls of the U-shaped long frame 152.

A long plate 168 is fixed in the middle of the outer wall of the thin shaft 167. The long plates 168 are respectively located on the left and right sides of the groove frame 164. Two arc-shaped spring pieces 169 are fixed on the outer wall of the thin shaft 167. The end of the arc-shaped spring piece 169 away from the thin shaft 167 is fixedly connected to the bottom surface of the groove frame 164.

The problem of carbon plate 165 being damaged is solved, and the operator bends the long plate 168 to rotate, the long plate 168 drives the thin shaft 167 to rotate, and the thin shaft 167 drives the arc-shaped spring piece 169 to rotate. The operator slides the new activated carbon plate 165 into the groove rack 164, loosens the long plate 168, and under the elastic force of the arc-shaped spring piece 169, the long plate 168 is reset in the U-shaped bar rack 166, thereby avoiding the problem of cumbersome equipment maintenance caused by the inconvenience of replacing the activated carbon plate 165 when the safety detection device is replaced.
