Abstract
It is little to the invention provides a kind of volume, and has the rubber-tube pressure gauge of overvoltage relief function concurrently, is used to indicate hydrodynamic pressure, is particularly useful for indicating the air pressure of bicycle tyre.The feature of this device is that a motion core is arranged.On the motion core overflow ducts is arranged.The motion core outer surface is with a rubber tube foldedly.One end of this rubber tube with connected by measuring pressure.The motion core by spring-loaded with balanced each other by measuring pressure.Tested force value is indicated by the position of motion core.Usually, overflow ducts is sealed by rubber tube, and when along with after being surpassed certain value by the displacement of the increase campaign core of measuring pressure, overflow is opened usually, realizes overflow.
Description
The present invention is a kind of spring manometer, is used to indicate hydrodynamic pressure, especially for the air pressure of indication bicycle tyre.
Existing spring manometer as spring-tube pressure gauge, bellows manometer etc., has a flexible member that produces corresponding displacement along with the variation of pressure.Because the displacement of this flexible member is less, is difficult to direct reading, and an enlarger also all will be arranged.Manometric volume will be increased.In addition, existing spring manometer does not generally have over-voltage protecting function.
Task of the present invention is the pressure gauge that a kind of volume of design can be done very for a short time, and makes it have the overvoltage relief function.
The present invention has a motion core.Outside surface from an end face of motion core to this motion core has overflow ducts.The close of motion core has that end face of overflow ducts to be connected with an end of an elastic rubber pipe, and ways of connecting is bonding or mechanical fixation.This rubber tube is enclosed within on the motion core foldedly, and overflow ducts is sealed.The other end of this rubber tube with connected by measuring pressure.A sleeve is arranged in the outside of rubber tube.This sleeve is connected with a joint.A spring is arranged, and this spring can be stage clip or extension spring, and an end links to each other with this joint or sleeve, and the other end acts on the motion core and by measuring pressure and balances each other.The motion core is along with being produced corresponding displacement by the variation of measuring pressure, and indicated the size of this pressure by the position of motion core.After being surpassed a certain ratings by measuring pressure, the overflow ducts of being sealed by rubber tube is opened, and realizes overflow, drops to ratings up to this pressure.
Compare with existing spring manometer, because the present invention has saved enlarger with motion core direct reading, so that volume can be done is very little; Because the present invention only uses general spring, cost is also reduced greatly simultaneously.In addition, the present invention also has the overvoltage relief function concurrently.
Accompanying drawing has been described one embodiment of the present of invention.
Fig. 1 is the longitudinal sectional drawing of this device.
This device has a motion core (4).Overflow ducts (4b) is arranged on motion core (4).Rubber tube (2) is enclosed within on the motion core (4) foldedly.One end (2a) of rubber tube (2) is bonded on the end (4a) of motion core (4).The other end (2b) of rubber tube (2) is counter to be enclosed within on the joint (1).Sleeve (3) is installed on the joint (1).Stage clip (5) places in the sleeve (3).Have window (3a) on the sleeve (3).The diverse location correspondence of motion core (4) different tested force value.This force value can be read from window (3a).Usually, overflow ducts (4b) is sealed by rubber tube (2).When along with after being surpassed certain value by the displacement of the increase campaign core (4) of measuring pressure, overflow ducts is opened, and realizes overflow.
