Abstract
The utility model relates to a pressure-measuring instrument, in particular to a pressure-measuring instrument to measure the pressure of a tire. The utility model is characterized in that the utility model is provided with a shell (1)whose front internal opening is provided with a finial; an air vent(8) is arranged beside the shell (1); a piston(2) provided with a sealing ring(6)is arranged inside the shell(1); a graduated rear sight(3) is arranged at the top of the piston and a spring(4) is arranged between the piston and a rear cover; a valve sealing ring(7) is arranged at the front internal opening of the shell. With simple structure, small size and light weight, the utility model is convenient to carry and is cheap and can be widely applied to measure the pressure of the tires of automobiles and motorcycles.
Description
One. technical field
The utility model relates to a kind of pressure-measuring instrument, particularly a kind of tire pressure measurement device.
Two. background technology
Air pressure in the automobile tyre has a significant impact road holding and safety, and hypertonia tire and contact area of ground diminish, and adhesive ability descends, easily cause danger when particularly meeting emergency braking, air pressure is crossed low resistance to motion and is become big, consumption increase, and reduce tire service life.For guaranteeing motor-driven vehicle going stable performance and safety, usually need tire pressure is checked, the usefulness that has kicks or experiences the interior gaseous tension of tire with excellent beaing, inaccurate easy generation misjudgment, there is a kind of its volume of tire pressure measurement instrument too big, heavy, not portable, and cost is too high, common people can't carry and use, and have only the unit of fewer specialty or personnel just to adopt.
Three. summary of the invention
It is small and exquisite, light that the purpose of this utility model is to design a kind of volume, is easy to carry about with one, cheap tire pressure measurement device.
The purpose of this utility model is to realize like this, a kind of tire pressure measurement device, be characterized in that a front end internal orifice is provided with top shell, top side is provided with an air extractor vent, be provided with piston in the shell, obturator piston ring is arranged on the piston, there is the rear sight of a band scale on the top of piston, be provided with spring between piston and bonnet, shell front end internal orifice has the valve sealing ring.
The tire pressure measurement device that provides by the utility model, during use with the valve of the top aligning detected tyre of shell internal orifice, with top roof pressure valve, gas in the tire enters in the shell jack-up piston, compression spring by the air extractor vent on top side, rear sight is ejected shell, the scale of reading on the rear sight is promptly known the gaseous tension that tire is interior, and chaufeur can be taked corresponding measure to the air pressure of tire in view of the above, guarantees the needs of driving a vehicle.The utility model is simple in structure, volume is little, in light weight, be easy to carry, cheap, can be widely used in the detection of automobile, motor vehicle wheel air pressure.
Four. description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1-shell, 2-piston, 3-rear sight, 4-spring, 5-bonnet, 6-obturator piston ring, 7-valve sealing ring, 8-air extractor vent
Five. the specific embodiment
Embodiment of the present utility model is described with reference to the accompanying drawings, as shown in drawings, a kind of tire pressure measurement device, be characterized in that a front end internal orifice is provided with top shell 1, top side is provided with an air extractor vent 8, is provided with piston 2 in the shell 1, obturator piston ring 6 is arranged on the piston 2, there is the rear sight 3 of a band scale on the top of piston 2, and 5 of piston 2 and bonnets are provided with spring 4, and shell 1 front end internal orifice has valve sealing ring 7.
