Referring to fig. 1 to 4, the experiment table base, the experiment table, the universal tube, the elastic block, the second air outlet and the fan provided by the embodiment of the utility model are existing devices.

Examples: referring to fig. 1 to 4, an embodiment of the utility model provides a laboratory safe operation experiment table, which comprises an experiment table base 1, wherein an experiment table 2 is fixedly installed on the experiment table base 1, and the laboratory safe operation experiment table is characterized in that a supporting block 3 is fixedly installed on the experiment table 2, a universal pipe 4 is arranged in the supporting block 3, a tooth slot 5 is arranged in the supporting block 3, and a placing block 6 is movably arranged on the supporting block 3.

Firstly, the inside of putting up the piece 6 both sides all elasticity is provided with bullet piece 7, and the edge arc setting of two bullet pieces 7 is mutually supported and is used between bullet piece 7 and the tooth's socket 5, when needs place universal pipe 4, in order not to hinder the operation of experimenter, can be realized through the shrink of bullet piece 7 and the resilience motion of resilience in tooth's socket 5 while adjustment put the piece 6 high.

Subsequently, take the inside of putting the piece 6 and seted up and put the groove 8, take and put the groove 8 and be the U-shaped groove, U-shaped groove and universal pipe 4 mutually support and use, can place universal pipe 4 on taking put the groove 8 through the U-shaped groove, be convenient for place, place and drop the damage, owing to take the design in groove 8U-shaped groove for can accord with the shape of universal pipe 4 more.

Further, one end of the universal pipe 4 is provided with a first exhaust port 9, and the first exhaust port 9 is a horn-shaped opening which is larger than the inner diameter of the first exhaust port 9, so that toxic gas can be absorbed more conveniently.

Still further, the second gas vent 10 has been seted up on the laboratory bench table 2, the exhaust hole 12 has been seted up to laboratory bench base 1 inside, exhaust hole 12 is linked together with the second exhaust hole 12, the bottom of universal pipe 4 passes the empty slot 11 intercommunication exhaust hole 12, the inside of exhaust hole 12 is provided with fan 13, can be with poisonous gas through the second exhaust hole 12 suction on the laboratory bench table, prevent the loss to other corners in laboratory, exhaust hole 12 is linked together with the second exhaust hole 12 simultaneously can save the resource more for just can realize absorbing harmful gas's function through a fan 13.

In order to facilitate the extension and movement of the universal tube 4, the hollow groove 11 for placing the universal tube 4 is formed in the experiment table base 1.

Finally, a driving motor for driving the fan 13 to rotate is arranged inside the fan 13.

And (3) assembly description: the vent hole 12 is communicated with the second vent hole 12, then the empty groove 11 is provided with a groove for the universal pipe 4 to be used and is communicated with the vent hole 12, the fan 13 is welded inside the vent hole 12, the bottom of the universal pipe 4 is communicated with the vent hole 12, the middle part of the universal pipe 4 is placed in the empty groove 11, the top of the universal pipe 4 penetrates through the empty groove 11 to enter the supporting block 3, then the placing block 6 is placed in the tooth groove 5 through the elastic blocks 7 on the two sides, and then the pipe orifice of the universal pipe 4 is placed in the placing groove 8 of the placing block 6, so that the assembly is completed.

The working principle of the laboratory safe operation experiment table provided by the utility model is as follows:

when the experiment is carried out on toxic gas, the height of the placing block 6 in the tooth groove 5 is adjusted, the placing block 6 is retracted into the placing block 6 due to elastic action when moving, so that the placing block 6 can move in the tooth groove 5, when moving to a toothless part in the tooth groove 5, the placing block 6 is fixed in the tooth groove 5 by the extension of the placing block 7, the universal pipe 4 is placed on the placing block 6 until normal experiment operation is not affected, the universal pipe 4 is pulled out by a required length, at the moment, the universal pipe 4 in the empty groove 11 is pulled out, the part of the universal pipe 4 in the supporting block 3 is lengthened, then the universal pipe 4 is pulled out to a required angle, at the moment, the universal pipe 4 can absorb toxic gas which is just generated and needs to be beaten out, the operation of an experimenter can be more convenient, the safety of the experiment environment is improved, and the toxic gas can be absorbed according to the needs of the experimenter.

Meanwhile, when toxic gas is sucked, part of the gas overflows, so that the universal pipe 4 cannot be completely absorbed due to misoperation, and the gas can be absorbed by the second exhaust port 10, so that the gas is prevented from escaping and scattered in the whole laboratory.
