Description
[technical field]
This utility model relates to Pressure gauge, particularly relates to the bourdon gauges that a kind of alarm indicator is dual-purpose.
[background technology]
Bourdon gauges belongs to indicator type Pressure gauge on the spot, it is possible to show the size of pressure on the spot, shows without teletransmission, regulatory function.Pressure deformation, by sensing element--the elastic deformation of Bourdon tube in table, is conducted to pointer again through the shifter of movement in table, is caused indicators turn to show pressure by bourdon gauges.Traditional bourdon gauges is used for fire extinguisher, can only indicate the pressure of fire extinguisher on the spot, it is impossible to under-voltage to fire extinguisher is reported to the police.
Application number be 201410148913.8 patent application disclose a kind of fire extinguisher red alarm device, it is sequentially connected with including fire extinguisher cylinder body, fixing apron, nozzle, handle, insurance draw ring, Pressure gauge, Mini alarm it is fixed with outside Pressure gauge, graduated disc is installed in Pressure gauge, graduated disc is installed pointer, being provided with tongue tube lower than pressure warning line place on graduated disc, red light emitting diodes is installed in graduated disc lower left, and button cell is installed in graduated disc lower right.Graduated disc must use non-ferrous material, and pointer must use magnetic material.This invention is for convenience of the leakage pressure detecting fire extinguisher intuitively, when fire extinguisher pressure is lower than warning line, pressure gauge for fire extinguisher pointer starts to be snapped down to red area security area, at this moment because pointer is magnetic, tongue tube is connected, red light emitting diodes and Mini alarm are simultaneously luminous and pipe, noticeable, remind people to process in time.The present invention can allow the fire extinguisher automatic sound-light alarm losing pressure, reminds people to reset in time fire extinguisher medicine, thus can be very safe.But, using tongue tube as manometric alarm switch, there is problems in that 1: tongue tube is installed relatively cumbersome, 2: adopt tongue tube must use Magnet, and magnetic attraction has certain space namely to work, it is impossible to accomplish precisely.
[summary of the invention]
The technical problems to be solved in the utility model is to provide a kind of simple in construction, is easy to assembling, the bourdon gauges that alarm indicator that pressure alarm accuracy is high is dual-purpose.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is, the bourdon gauges that a kind of alarm indicator is dual-purpose, including watchcase, joint, bourdon tube, pressure display organ and alarm mechanism, pressure display organ includes dial plate, pointer and needle pivot；The fixing end of bourdon tube is connected with joint, and movable end drives needle pivot, alarm mechanism to include alarm switch and drive block by connecting rod, and alarm switch is fixed on the dial plate back side, and drive block is fixed on bourdon tube, near movable end；During bourdon tube deformation, touch alarm switch by drive block.
Above-described bourdon gauges, alarm mechanism includes support, and support is fixed on the back side of dial plate, and alarm switch is fixed on support.
Above-described bourdon gauges, dial plate includes hole, two location, and the front of support includes two alignment pins, and the alignment pin in support front is inserted in the hole, location of dial plate；Alarm switch includes hole, two location, and the back side of support includes two alignment pins, and the alignment pin of cradle back is inserted in the hole, location of alarm switch.
Above-described bourdon gauges, described alarm switch is microswitch, and the reed of microswitch or button are towards bourdon tube, and the inner side of drive block is against on reed or the button of microswitch.
Above-described bourdon gauges, alarm mechanism includes signal accessory power outlet, and signal accessory power outlet is fixed on watchcase, and signal accessory power outlet electrically connects with alarm switch.
Above-described bourdon gauges, signal accessory power outlet is fixed on the bottom surface of watchcase, and socket is outwardly.
Above-described bourdon gauges, drive block is U-shaped, and bourdon tube is inserted in the U-lag of drive block.
Above-described bourdon gauges, drive block and bourdon tube are adhesively fixed.
Above-described bourdon gauges, when bourdon tube shrinks, touches alarm switch by drive block.
Bourdon gauges simple in construction of the present utility model, being easy to assembling, pressure alarm accuracy is high.
