Abstract
The utility model relates to a tyre pressure gauge which comprises a contact head, a shell body, a pressure ring, a scale and a telescopic spring, wherein the contact head is provided with a joint matched with an air tap of a tyre, and an air hole penetrating through both ends of the contact head; a raised head which can push away a tyre valve core is arranged in a joint of the contact head; the pressure ring in the shell body is positioned on the outlet end of the air hole of the contact head and is abutted with the scale; the pressure ring is abutted with the telescopic spring; the scale can extend out of the shell body. When the pressure is measured, reading data of the scale, which extends out, as the tyre pressure value is red. The utility model is as small as a pen and can be carried about.
Description
The utility model relates to a kind of the measurement and display of tyre pressure tires tensimeter.
As everyone knows, the tire pressure of various vehicles such as automobile, motorcycle, vehicle using motor is unsuitable too high or too low, hypertonia can cause tyre explosion, hypotony can add utmost point tire wear, influence travel speed and increase oil consumption, tend to cause traffic hazard, especially on highway and blow out, blow out and will cause the heavy losses of lives and properties, visible tire pressure detects very important.But existing tire pressure gauge exists volume big, and quality is heavy, and glass surface is frangible and use shortcoming such as inconvenience, is unfavorable for carrying and detects at any time.
The purpose of this utility model provides a kind of tire pressure gauge that is suitable for carrying, and it is small-sized, light, and is simple to operate, is convenient to carry.
The utility model tire pressure gauge comprises contact, housing, pressure coil, scale and coil tension spring, the front end of contact is provided with the interface that can match with cranked tire valve, the top of rear end and housing joins, be provided with the pore that connects two ends in the contact, be provided with the plush copper that can back down tyre valve core in the contact interface, the pressure coil in the housing is positioned at the endpiece of contact pore, and offsets with scale, pressure coil and coil tension spring offset, and scale can stretch out from housing.Inner walls is equipped with one section cushion cover that the motion of scale is play the guiding role; Be provided with packing washer in the interface of contact, be provided with the gap that communicates with the contact pore between this packing ring and the plush copper.The housing of this tire pressure table can be the tubular structure of penholder type, and this tubular shell is equipped with pen clip.
This tire pressure table can be made into a sample size, carries very convenient.During use, only need the interface of contact is inserted the valve of tire, pressed gas in the tire promptly promotes pressure coil and scale is stretched out from the end of housing by pore, the length that scale stretches out is directly proportional with tire pressure, therefore tire pressure value can show that pressure measurement is easy to operate by rod reading.
Below in conjunction with description of drawings example structure of the present utility model.
Accompanying drawing is the utility model pen type tire pressure gauge example structure figure.
As shown in the figure, be provided with pressure coil 3, scale 7, coil tension spring 5 in the tubular body shell 6, the rear end of contact 2 and housing 6 are pegged graft the two immovable fitting; The front end of contact is provided with interface 2-1, is provided with plush copper 2-2 and packing washer 1 in the contact, and is gapped 9 between plush copper and the packing ring, and the pore 2-3 that connects two ends in this gap and the contact head is connected; The effect of packing ring 1 is to make air-flow all enter pore 2-3, unlikely sewing.Pressure coil 3 is positioned at the endpiece of the 2-3 of pore, and links to each other with scale 7, and pressure coil 3 offsets with scale 7, and the two is chorista each other.The two ends of coil tension spring 5 are between pressure coil 3 and guiding cushion cover 8.During use, joint 2-1 is inserted on the cranked tire valve, make plush copper 2-2 unseat the valve core, Pneumatic pipe cleaner in the tire crosses gap 9 and pore 2-3 acts on pressure coil 3, pressure coil is promoted and drives scale and moves right by air pressure, scale stretches out certain-length outside housing, and spring 5 is compressed simultaneously.Reading scale stretches out the outer reading of shell and is tire pressure value.When contact leaves tire, air pressure disappears, pressure coil 3 return left under spring 5 effects, and scale is then left alone without help to be stayed on the reading of indication tire pressure.The present embodiment external form is provided with pen clip 4 like pen, can carry.
