Abstract
The utility model discloses a hydraulic braking safety alarm which solves the technical defects of low alarming sensitivity, short service life and unadjustable pressure. The utility model has the main technical scheme that the hydraulic braking safety alarm comprises a casing in which a hollow cavity is arranged, and the bottom of the hollow cavity is provided with a demountable end cover. An oil inlet and an oil outlet are communicated with the hollow cavity, and the upper side of the casing is provided with a magnetic switch. The oil inlet and the oil outlet are arranged at a left and a right sides at the upper part of the casing, a support ring is arranged in the hollow cavity of the casing and the upper side of the support ring is provided with a pallet. A soft diaphragm is extruded between the upper lateral surface of the pallet and the casing, and the upper side of the soft diaphragm and the corresponding position of the magnetic switch are provided with magnetic cores. A plunger piston which can support and press the soft diaphragm freely penetrates the pallet and is supported on a spring seat, and the end cover is provided with an adjusting screw. A compression spring is arranged between the spring seat and the adjusting screw. The utility model has the advantages of simple structure, high alarming sensitivity, long service life and adjustable pressure and is used for various motor vehicles.
Description
Technical field
The utility model relates to safety device of vehicle, exactly is the water brake safety alarm.
Background technology
At present, the water brake safety alarm kind that is applied to self-propelled vehicle is a lot, and vehicle safety has been played certain protective role.Shortcomings such as but it is low that its ubiquity warning sensitivity, and it is untimely to report to the police, and service life is short, and pressure is unadjustable, and field of application is little are directly threatening driver and crew and autre vie safety to a great extent.
Summary of the invention
Technical problem to be solved in the utility model is: just provide a kind of water brake safety alarm, it can use simple structure, and it is low to solve warning sensitivity, and service life is short, the uncontrollable technological deficiency of pressure.
For solving the problems of the technologies described above, the technical solution of the utility model is: the water brake safety alarm, comprise that inside is provided with the housing of cavity, the bottom of cavity is provided with detachable end, advance, oil outlet is communicated with described cavity, the upside of described housing is provided with magnet-switch, describedly advance, oil outlet is located at the left side on housing top, right both sides, be provided with support ring in the cavity of housing, the upside of support ring is provided with pallet, be extruded with flexible partition between the upper side of pallet and the housing, flexible partition upside and magnet-switch corresponding position are provided with magnetic core, but the plunger of roof pressure flexible partition freely passes pallet and leans on spring perch, and end cap is provided with trimming screw, is provided with compression spring between spring perch and the trimming screw.
Owing to adopted technique scheme, when brake solution enters the housing inner chamber by oil inlet, chamber pressure is during greater than setup pressure value, and brake solution promotes magnetic core and flexible partition moves downward, and magnet-switch and the increase of magnetic core spacing are not reported to the police.On the contrary, when brake system has leakage of oil, when the pressure of housing inner chamber was lower than setting pressure, flexible partition and magnetic core then can upward movements, and magnetic core is reported to the police near magnet-switch.As required, trimming screw changes the setting value of housing chamber pressure by the pressure of adjusting compression spring.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structure cutaway view of the utility model embodiment.
The specific embodiment
As shown in drawings, the water brake safety alarm comprises that inside is provided with the housing 1 of cavity, and the bottom of cavity is provided with detachable end 13, the upside of housing 1 is provided with magnet-switch 2, and what be communicated with cavity is located at the and arranged on left and right sides on housing top into and out of hydraulic fluid port 3,4.Be provided with support ring 11 in the cavity of housing 1, the upside of support ring 11 is provided with pallet 7, be extruded with flexible partition 5 between the upper side of pallet 7 and the housing 1, flexible partition 5 upsides and magnet-switch 2 corresponding positions are provided with magnetic core 6, the plunger 8 of roof pressure flexible partition 5 freely passes pallet 7 and leans on spring perch 12, end cap 13 is provided with trimming screw 10, is provided with compression spring 9 between spring perch 12 and the trimming screw 10.
Its working process is: when brake solution enters housing 1 inner chamber by oil inlet 3, chamber pressure is during greater than setup pressure value, and brake solution promotes magnetic core 6, flexible partition 5 and plunger 8 and moves downward, and magnet-switch 2 increases with magnetic core 6 spacings, does not report to the police.On the contrary, when brake system has leakage of oil, when the pressure of housing 1 inner chamber was lower than setting pressure, 8 of flexible partition 5, magnetic core 6 and plungers can upward movements, and magnetic core 6 is reported to the police near magnet-switch 2.As required, trimming screw 10 changes the setting value of housing chamber pressure by the pressure of adjusting compression spring 9.The utility model is simple in structure, the warning sensitivity height, and long service life, pressure can be regulated, and is widely used in all kinds of self-propelled vehiclees.
