Description
Technical field
The utility model relates to a kind of architecture advances of hydraulic pressure switch.
Background technology
A common hydraulic pressure switch is provided with diaphragm, push rod, cross bar, feeler lever, spring and switching electric contact in shell chamber.When work, water injects shell chamber from water inlet, and promote diaphragm and move upward, the up promotion cross bar of push rod being connected with diaphragm, one end of cross bar promotes feeler lever, the contact of one end of feeler lever and the energising contact touching of being located at shell cavity wall, power connection, switch opens; Idle, promotes diaphragm by the tension force of spring descending, seals water inlet, and now the contact of feeler lever one end departs from energising contact and touches with the breaker point of being located at below, energising contact, and power supply disconnects, and switch cuts out.Owing to having adopted the mechanical system of multiple layers transmission, this type of hydraulic pressure switch structure is comparatively complicated, and reliability is not high, and durability is bad.
Utility model content
The utility model discloses a kind of hydraulic pressure switch, can effectively improve the existing above-mentioned defect of existing hydraulic pressure switch.
Technical solution adopted in the utility model is:
A kind of hydraulic pressure switch, comprises upper cover and lower cover; The bottom surface of described upper cover is provided with press box, and described press box is plugged in the set lid chamber of described lower hd top face, and the periphery of a flexible sheet that is layed in bottom, described lid chamber is fixed;
On the described lower cap body of described flexible sheet below, have the water inlet communicating with described lower cover cavity.
The end face central authorities of described flexible sheet are provided with a conductive contact blade, the end face central authorities of described conductive contact blade are provided with a spring stack, described spring stack is socketed with a back-moving spring, the top of described back-moving spring is socketed with the adjusting screw(rod) of an adjustable described back-moving spring degree of tightness, and what described adjusting screw(rod) was arranged at that described upper cap body central authorities open one regulates in through hole.
On the upper cap body of described adjusting through hole both sides, be respectively provided with a conductive pole, the top of described conductive pole is provided with stretches out outside described upper cap body, and its top is provided with binding post, and the bottom of described conductive pole probes in described lower cover lid chamber.
Transferring structure of the present utility model only relates to diaphragm, conductive contact blade, back-moving spring and conductive pole, and structure is comparatively simple, has higher reliability and better durability.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment
Fig. 2 is Fig. 1 explosive view
Fig. 3 is the utility model embodiment working state structure schematic diagram
In figure, be labeled as: 1, upper cover, 1a, press box, 1b, regulate through hole, 2, lower cover, 2a, lower cover lid chamber, 2b, water inlet, 3, flexible sheet, 4, conductive contact blade, 5, spring stack, 6, back-moving spring, 7, adjusting screw(rod), 8, the first conductive pole, 9, the second conductive pole.
Specific embodiment mode
Below in conjunction with the drawings and specific embodiments, the utility model is described.
A kind of hydraulic pressure switch, comprises upper cover 1 and lower cover 2;
The bottom surface of upper cover 1 is provided with press box 1a, and press box 1a is plugged in the set lower cover lid chamber 2a of lower cover 2 end faces, and the periphery of a flexible sheet 3 that is layed in bottom, 2a lid chamber is fixed;
On lower cover 2 lids of flexible sheet 3 belows, have the water inlet 2b communicating with lower cover cavity 2a.
The end face central authorities of flexible sheet 3 are provided with a conductive contact blade 4, the end face central authorities of conductive contact blade 4 are provided with a spring stack 5, spring stack 5 is socketed with a back-moving spring 6, the top of back-moving spring 6 is socketed with the adjusting screw(rod) 7 of adjustable back-moving spring 6 degrees of tightness, and what adjusting screw(rod) 7 was arranged at that upper cover 1 lid central authorities open one regulates in through hole 1b.
On upper cover 1 lid of adjusting through hole 1b both sides, be respectively equipped with first, second conductive pole 8,9, the top of first, second conductive pole 8,9 is provided with stretches out outside upper cover 1 lid, top is equipped with respectively binding post, and the bottom of first, second conductive pole 8,9 probes in lower cover lid chamber 1a.
The course of work of the present utility model is: when work, as shown in Figure 3, water upwards injects lower cover lid chamber 2a from water inlet 2b, and upwards the flexible sheet 3 of lower cover lid chamber 2a bottom is located in extruding, because the periphery of flexible sheet 3 is pushed down by press box 1a, its middle part lamellar body is promoted to raise up by water, drives that to be located at the conductive contact blade 4 of its end face up, until the bottom touching of conductive contact blade 4 and first, second conductive pole 8,9, turn-on power, now, power connection, switch opens; Idle, as shown in Figure 1, cuts off the water supply, and back-moving spring 6 promotes successively conductive contact blade 4 by spring stack 5 and flexible sheet 3 resets, and power supply disconnects, and flexible sheet 3 is by water inlet 2b sealing, and switch cuts out.
