Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Referring to Fig. 1, the present invention provides a kind of technical scheme：
A kind of pressure sensor with warning function, including support tube 3, the support tube 3 are made up of transparent acrylic material,
The upside of support tube 3 is provided with pressure gauge 2, and the upside of pressure gauge 2 is uniformly provided with contact chip 1, the side wall of support tube 3
Right side upper end is provided with air inlet 4, and the screw-internal thread fit of air inlet 4 has vice 5, and the vice 5 is made up of elastomeric material
And coordinate with the screw thread of air inlet 4, negative plate 8, the inwall of support tube 3 left side are installed with the right side of the inwall of support tube 3
Rotatable engagement has positive plate 6, the positive plate
6 length is more than the internal diameter of support tube 3, and rotating shaft 15, the positive plate 6 are connected between the positive plate 6 and support tube 3
The first helical spring 7 is installed between downside surface and support tube 3, the left side central portion of support tube 3 is installed with police
Show lamp 16, the positive plate 6 is electrically connected with warning lamp 16 by wire, and symmetrically through hole is provided with the downside of the side wall of support tube 3
9, the symmetrical screw thread in the surface of support tube 3 is combined with screw rod 14, and the outer end of screw rod 14 is welded with block 13, the table of screw rod 14
