Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Examples

Referring to fig. 1-5, the present invention provides a technical solution: an indoor air quality detection sampling analysis tube comprises an absorption tube 1, one side of the absorption tube 1 is communicated with a first air outlet pipe 4, one end, far away from the absorption tube 1, of the first air outlet pipe 4 is provided with a first plate body 9, one side of the first plate body 9 is attached with a second plate body 8, one side, far away from the first plate body 9, of the second plate body 8 is provided with a second air inlet pipe 5, one end, far away from the second plate body 8, of the second air inlet pipe 5 is communicated with a safety bottle 6, one side of the second plate body 8 is symmetrically bonded with two first toothed plates 11, one side of the first plate body 9 is symmetrically provided with two through grooves 16, the two first toothed plates 11 are respectively inserted into the two through grooves 16, the inside of the two through grooves 16 is provided with a second toothed plate 15, the second toothed plate 15 is matched with the first toothed plates 11, one side, far away from the first toothed plates 11, is welded with a pull rod 10, the inside of the first plate body 9 is symmetrically provided with two cavities 13, the two pull rods 10 respectively penetrate through the two cavities 13, the baffle 14 is adhered to the outer side wall of the pull rod 10 located inside the cavity 13, the spring 12 is arranged on the upper surface of the baffle 14, and the outer side wall of the pull rod 10 is sleeved with the spring 12.

As shown in fig. 1: the top of the absorber pipe 1 has a first sealing plug 3; with the above arrangement, the absorption tube 1 can be sealed to facilitate sampling of air.

As shown in fig. 1: a first air inlet pipe 2 is inserted in the first sealing plug 3; through the above arrangement, air can more conveniently enter the inside of the absorption tube 1.
