Detailed Description
The alarm device comprises a float component 1, a tank body 2 and an alarm terminal component 3, wherein a wiring terminal 301 of the alarm terminal component 3 is fixedly connected with the outside of the tank body 2, an alarm terminal 302 is fixedly connected in a float cavity 201 of the tank body 2, and the float component 1 is sleeved on the outside of the alarm terminal 302 and is in sliding connection with the alarm terminal 302; the ring magnet 102 in the float member 1 causes the reed 30301 to connect or disconnect by magnetizing the reed 30301 in the reed tube 303.
The float component 1 comprises an annular upper float body 101, an annular magnet 102 and an annular lower float body 103, wherein the upper part and the lower part of the annular magnet 102 are respectively in interference fit with the annular upper float body 101 and the annular lower float body 103, and are not allowed to fall off.
The density of the annular upper float body 101 and the annular lower float body 103 is less than that of brake fluid, and the adopted material is polypropylene material with foaming agent added, so that the float body drives the magnet to move up and down in the brake fluid through buoyancy.
The inside of jar body 2 is equipped with float cavity 201, and the effect is that brake fluid bumps the float part and leads to the wrong report to police when preventing the automobile vibration.
The alarm terminal component 3 comprises a wiring terminal 301, an alarm terminal 302, a reed pipe 303, an upper float positioning 304 and a lower float positioning 305, wherein the wiring terminal 301 is fixedly connected with the alarm terminal 302, the alarm terminal 302 adopts a cylindrical shape, the reed pipe 303 is fixedly connected in the alarm terminal 302, the reed pipe 303 is electrically connected with the wiring terminal 301, the upper float positioning 304 is sleeved on the upper part of the alarm terminal 302, and the lower float positioning 305 is fixed at the bottom of the alarm terminal 302.
