Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment, based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution: a kind of atmospheric density instrument for laboratory environment,
Including densimeter main body 1, the corresponding position of 1 inside upper and lower ends of densimeter main body is equipped with installation partition 2, densimeter main body
1 mounted partition 2 divides to survey room 3 and installation room 4, and installation 4 side of room is equipped with hydraulic cylinder 7, and 7 one end of hydraulic cylinder, which is connected with, stretches
Contracting bar 6,6 one end of telescopic rod are welded with push plate 5, and push plate 5 is surrounded by sealing rubber ring 12, survey 3 one end of room and are equipped with mounting base
8, installation groove 9 is offered inside mounting base 8, and internal screw thread is equipped with inside installation groove 9, installing pipe is installed in installation groove 9
10, it is equipped on the outside of installing pipe 10 and external screw thread that internal screw thread matches, control valve 11 is installed in installing pipe 10.
Installation partition 2 is welded on 1 inner wall of densimeter main body, and installation 4 one end of room is also provided with several through-holes, and push plate 5 is set
