Abstract
A pressure detecting indicator includes a cylinder, a seal ring and a valve driving part. The cylinder is sleeved with a tectum which has a transparent middle part, the valve driving part with an intake via is connected in the cylinder by a thread, an elastic membrane is provided between the valve driving part and the tectum, a pressure indication tube is provided on the elastic membrane, a spring is provided between the pressure indication tube and the tectum. The surfaces of the elastic membrane and the pressure indication tube both have patterns or color which indicates the pressure change, an indicative line is provided at the lower edge of the opaque part of the tectum; a graduation line is provided on the surface of the pressure indication tube. The utility model has simple structure, low manufacturing cost and convenient usage, by which the pressure changes of the pressure device and the pneumatic device can be indicated visually, the utility model is particularly applicable for the detection indication of the automobile tire pressure.
Description
Technical field
The utility model relates to a kind of gas, hydrodynamic pressure detects indicator, and especially a kind of tire pressure that is used for detects the pressure detection indicator of indicating.
Background technology
At present, keep suitable air pressure for making doughnut, guarantee the security and the economy of car load, often to the air pressure of doughnut be detected, detection method mainly contains range estimation and detects with the hand-held gas-pressure survey meter, the former is rule of thumb often inaccurate, it is very inconvenient that the latter need arrive special tyre service station, and accumulation testing cost height, more can not correctly detect the air pressure of tire especially at any time at the vehicle of running on expressway, therefore, be difficult to guarantee the safety traffic of vehicle, and have the vehicle of tire pressure automatic detection device, the manufacturing of this device, the operation and maintenance cost is all very high, can't popularize use.
Summary of the invention
The purpose of this utility model is the pressure detection indicator that will provide a kind of simple in structure, low cost of manufacture, pressure easy to use, indicated pressure equipment and pneumatic equipment intuitively to change, and is specially adapted to the detection indication of air pressure of automobile tire.
For achieving the above object, the technical solution of the utility model is: a kind of pressure detection indicator, comprise cylinder body, O-ring seal and valve actuator, be with the transparent top cover in middle part on the cylinder body, be connected with the valve actuation part that has the air inlet through hole by screw thread in the cylinder body, be provided with elastic membrane on the valve actuation part and between the top cover, elastic membrane is provided with the air pressure indicator drum, is provided with spring between air pressure indicator drum and the top cover.The gentle pressure indicator drum of elastomeric film surface surface is equipped with pattern or the color that indicated pressure changes, and top cover opaque section lower edge is provided with index line; Air pressure indicator drum surface is provided with scale mark.
The utility model has been owing to adopted above technical scheme, and therefore the beneficial effect that is had is that simple in structure, low cost of manufacture, applicability are strong.Pattern by the gentle pressure indicator drum of elastomeric film surface surface or the color pressure of indicated pressure equipment and pneumatic equipment intuitively change; But also can be fixed on continuous uninterrupted indicated pressure value and pressure variation on press device and the pneumatic equipment by scale mark indicated pressure equipment on the gentle pressure indicator drum of the index line on the top cover and the concrete force value in the pneumatic equipment, also can be used for the indication of hand-held single.Can replace the valve cap on the tyre valve when being used on the tire especially, be used to refer to the variation of tire pressure.
Description of drawings
Fig. 1 is the structural drawing before the utility model inflation.
Fig. 2 is the structural drawing after the utility model inflation.
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.In Fig. 1, the pressure detection indicator, comprise cylinder body 7, O-ring seal 6 and valve actuator 5, be with the transparent top cover in middle part 1 on the cylinder body 7, index line is carved with in top cover 1 opaque section lower edge, have and have air inlet through hole 8 on the valve actuation part 5 of O-ring seal 6 and be connected with cylinder body 7 by screw thread, be provided with elastic membrane 4 on the valve actuation part 5 and between the top cover 1, elastic membrane 4 is provided with air pressure indicator drum 3, between air pressure indicator drum 3 and the top cover 1 compression spring 2 is housed, elastic membrane 4 surperficial gentle pressure indicator drums 3 surfaces are equipped with pattern or the color that indicated pressure changes; Air pressure indicator drum 3 surfaces are provided with scale mark.During use, cylinder body 7 is fixed on the tyre valve, valve actuation part 5 is opened the valve cock plunger tip, gas in the tire enters by the through hole on the valve actuation part 58 elastic membrane 4 is opened, when the air pressure of tire during at setting, 4 of elastic membranes are to maximum, and the original pressure that the air pressure indicator drum 3 above promoting overcomes spring 2 moves in top cover 1 opaque section, as shown in Figure 2, can see pattern or color on the complete elastic membrane 4 by top cover 1 transparent part.When tire pressure reduces, spring 2 in the top cover 1 promotes air pressure indicator drum 3 readjustments, make air pressure indicator drum 3 part surfaces be positioned at top cover 1 transparent part, because air pressure indicator drum 3 surfaces are provided with different patterns or color at different positions, therefore, by observing the variation of top cover 1 interior pattern or color, can judge the variation of tire pressure intuitively, in addition, by observing the scale mark that air pressure indicator drum 3 surfaces that eye-catching index line that top cover 1 opaque section lower edge is provided with aims at indicate, can understand concrete tire pressure value roughly.
