Abstract
The utility model discloses a cylinder type tyre barometer for small automobile which is a finger-sized cylinder, comprising a shell and an inner cavity which is composed of a piston push rod, a pressure spring, a scale cylinder, a guiding and adjusting plug and a seal ring. The middle of the shell is provided with a viewing hole, the axial direction of the shell is provided with a long slot where the handle of the scale cylinder can move, the rear end of the shell is provided with an inner thread which the guiding and adjusting plug can be screwed on, the front bottom of the shell is provided with small exhaust holes. The piston push rod is jacketed with the guiding and adjusting plug, the pressure spring is jacketed at the outside of the guiding and adjusting plug, the scale cylinder is jacketed at the outside of the pressure spring, the attached handle of the scale cylinder is slid into the long slot of the shell, the scale on the scale cylinder is displayed in the viewing hole, sealing ring is arranged respectively at the inside of the front bottom of the shell and at the piston. The utility model has small volume and is convenient for use as a hanging part of key ring, and also has convenient application that the gas pressure of automobile tyre can be known at any time as a necessary article for car driver.
Description
Technical field
The utility model relates to the detecting instrument of air pressure of automobile tire, especially refers to a kind of portable kart cartridge type tire gauge.
Background technology
Current society, economically developed, people's people's livelihood words level generally improves, and automobile becomes the popular vehicles gradually.And tire is the important component part of automobile.The tire pressure of standard is again the important leverage of vehicle safety travel.At present, the car that much travels all exists tire pressure potential safety hazard higher or on the low side.Air pressure is low excessively, quickens tyre injury, the too high danger that the fried tire of generation is arranged again.These unsafe factors, especially the speed of a motor vehicle is very fast on highway, and tyre pressure is one of problem of worrying most of driver.Therefore, want before going out car, to detect the air pressure of tire, just must standby air pressure testing tool, therefore, the utility model will bring convenience to the car human pilot.
The utility model content
The purpose of this utility model is: provide a kind of small portable testing tool of the air pressure of measuring wheel voluntarily to the car human pilot, can grasp tire pressure at any time, increase the safety guarantee of running car.
The technical scheme that the utility model adopted is: the utility model is made up of with adjustment plug screw and O-ring seal watchcase, piston push rod, pressure spring, scale drum, guiding.Described watchcase is a hollow cylindrical tube, and the position has observation port therebetween, is axially arranged with the elongated slot for the handle activity of scale drum, and the rear end of housing is provided with the internal thread that screws in for guiding and adjustment plug screw, and front bottom end is provided with exhaust hole.
The outside of described piston push rod be with guiding with adjust plug screw to cylindrical shell, its thread end is spun in the internal thread of housing rear end, pressure spring is enclosed within guiding and the outside of adjusting the plug screw cylindrical shell, scale drum is enclosed within the outside of pressure spring, the attached handle of scale drum slips in the elongated slot of housing, and the scale on the scale drum is emerging in the observation port.
Described O-ring seal is arranged on the inboard of housing front bottom end, is with the piston push rod O-ring seal on the piston of piston push rod, and the external diameter of two O-ring seals all internal diameter with housing is identical.
The utility model volume is small and exquisite, is convenient to carry as the suspension member of key-ring, uses very conveniently, can understand the air pressure of doughnut at any time, is the thing of the indispensability of car human pilot.

Embodiment
As shown in Figure 1, the utility model by cylindrical housings and be arranged on inner chamber piston push rod 4. pressure spring 5, scale drum 6 and guiding and adjustment plug screw 7 etc. are formed.Driven the observation port 8 that appears baroscale at the middle part of housing 2, housing 2 axially have an elongated slot 9, the handle of being convenient to scale drum 6 is up and down.The outside of piston push rod 4 is with guiding and adjusts plug screw 7, and pressure spring 5 is enclosed within guiding and adjusts outside the cylindrical shell of plug screw 7, and the plug screw of its outer end screws in the internal thread of housing 2 rear ends.Piston portion at piston push rod 4 is lined with piston push rod O-ring seal 3, with the inner wall sealing of housing 2.Inboard in housing 2 front bottom end also is lined with O-ring seal 1.During the detection wheel air pressure, housing 2 front ends are aimed at cranked tire valve, the unseat the valve core, the tire compressed air enters housing 2 by exhaust hole 10, piston push rod 4 is advanced backward, and then promotion scale drum 6, under guiding and adjustment plug screw 7 act on, scale drum 6 can only straight ahead, when bounce after pressure spring 5 compresses and tire pressure thrust balance each other, piston push rod 4 and scale drum 6 stop to move, the scale label that seen this moment from the observation port 8 of housing 2, the tire pressure that is detected exactly.After finishing using, housing 2 leaves cranked tire valve, and under the bounce-back of pressure spring 5, piston push rod 4 resets, and the air in the housing 2 is discharged from vent port 10, and scale drum 6 can push with attached handle and reset.
