Abstract
The utility model relates to a spring pointer type tyre pressure gauge, comprising a gauge main body, a main spring and a piston. The utility model is characterized in that the q-shaped gauge main body is composed of a dial plate and a guide sleeve, one end of the guide sleeve is connected with an exhaust valve and an air measuring valve, the inner part of the guide sleeve is provided with the piston, a piston draw rod and the main spring which is sheathed on the draw rod, the dial plate is provided with a pointer part, a center gear engage with a fan-shaped wall and a rubbing steel wire. The utility model has the advantages of convenient carrying, low cost, high roughness, high stability, convenient operation and long service life, and the utility model can save large numbers of non-ferrous metal and is suitable for inner pressure detection of various vehicle inflated tyres.
Description
The utility model belongs to tire pneumatic pressure detector, particularly a kind of spring pointer-type tire gauge.
At present, tire pneumatic pressure detector mainly shows by tensimeter, and the structure more complicated, and price is higher.On the market two types tire gauge is arranged now: a kind of is that accepted scale stretches out how much come the measuring pressure value, and main body becomes two bodies with the tire interface, the structure disunity, therefore, this meter accuracy is low, error more greatly, not directly perceived again.Another kind of tire pressure gauge is to adopt bourdon tube as flexible member, though more preceding a kind of raising of precision, corresponding cost also increases, and body is big, inconvenient operation.
It is little that the purpose of this utility model provides a kind of profile, spring pointer-type tire gauge simple in structure, that cost is low, precision is high.
The utility model spring pointer-type tire gauge comprises the table main body, and main spring and piston is characterized in that: the table main body that is the q font is made up of circular dial plate and the cylindrical guide pin bushing of connection all-in-one-piece, and an end of guide pin bushing connects vent valve, surveys air valve; Piston, pitch brace are housed in the guide pin bushing successively and are sleeved on main spring on the pull bar; Indicating members is equipped with on the top in dial plate centre, centre wheel that is meshed with sectional wheel and the friction steel wire that is stuck on the centre wheel are equipped with in the bottom, the two ends of friction steel wire are fixed with an end of zeroing wheel and table main body respectively, the central point of sectional wheel is actively connected on the dial plate, and the other end contacts with pull bar point.
Principle of work of the present utility model is: the pressure in the tire acts on the piston through surveying air valve, makes the main spring stress deformation produce displacement, drives sectional wheel, by analog to digital conversion, drives indicating members by centre wheel, indicates the pressure measurement value on dial plate.
Compared with the prior art the utility model has the following advantages:
1, the table main body is combined as a whole fluid passage and instruction unit, and this table is easy to carry, be convenient to operate.
2, cost is low, precision is high, good stability, long service life.
3, can save a large amount of coloured precious metals.
The utility model is provided by the following drawings and embodiment.
Fig. 1 is an outside drawing of the present utility model.
Fig. 2 is an one-piece construction cut-open view of the present utility model.
Fig. 3 is the left view of Fig. 2.
The utility model instrument structure such as Fig. 2, shown in Figure 3, table main body (13) top meta is provided with centre wheel (11) sectional wheel (2) and is fixed on table main body (13) the side locating shaft by pressing plate (1), make with centre wheel ledrite HPB59-1 material, sectional wheel (2) adopts the ABS plastic material to make, this material has certain intensity, again can once-forming, the two engagement effect is reasonable, torsion spring is placed on sectional wheel after the engagement (2) top, this torsion spring one end is fixed in table main body (13) side position one end and is fixed on the sectional wheel (2), play damping action, the table main body fixing zeroing wheels in (13) one distolateral holes (3), enter table main body (13) part, fixed friction steel wire (4) one ends, friction steel wire (4) is gone up the axle tangentially with centre wheel (11) and is fixed in table main body (13) other end, play the zeroing effect, place main spring (9) in table main body (13) the bottom guide pin bushing (14), pull bar (8) one end fixed pistons (7), the other end passes main spring (9) in table main body (13) bottom guide pin bushing (14), survey air valve, vent valve (6) adopts T-3 6 glue to be fixed in guide pin bushing (14) one ends, ring Φ 8 holes meet that " the QC/T14-32 industry standard is that O-ring seal (5) is positioned over to survey in air valve Δ 8 holes and plays air admission hole and the effect of cranked tire valve sealing joint, and sealing circle coloured silk intensity is at 180-250kg/cm in this part
2Neoprene make, have advantages such as intensity height, price be low, dial plate (10) adopts aluminium sheet LT12 material, scale meets the requirement of " QL/T14-92 industry standard ", font meets the requirement of " QB4457.3-81 ", indicating members (12) is gone up watch glasses and is adopted concave structure, and material adopts organic glass, and adaptability is stronger.
