Abstract

The utility model relates to a vehicle tyre pressure-relieving detector. The lower part of a shell cap of the upper part of a shell body is orderly provided with a sealing rubber skin bowl and a partition board which is provided with a pressure board. The lower surface of the partition board is fixedly provided with two contacts. Conducting wires are led out of the two contacts. The inner part of the shell body is provided with a spring. The upper end of the spring is fixedly provided with a movable contact sheet, and the lower end of the spring is fixed on a lower top board. The conducting wires are connected with an alarm circuit. A joint on the shell cap is connected with a tire valve core of a rubber pipe. When a tyre relieves pressure, the two fixing contacts are used for switching on the circuit to give an alarm. The utility model has the advantages of simple structure and low cost, and can make a driver know the pressure-relieving condition of a vehicle tyre for reducing loss.

Description

Motor tire pressure release detector

The utility model relates to motor tire.

Be that the autotruck of twin tire is difficult to find whether deficency or do not had gas, particularly inside tire of one of them tire for trailing wheel when long-distance transport.Mode commonly used is a manual detection after car stops, this is pretty troublesome for long-distance driving, the driver generally is unwilling to stop for this reason and specially, thereby often cause a tire deflation or do not have gas not know and continue the driving, cause another tire list tire load-bearing and acutely rubbed by the tire of deficency, two tires are together scrapped, caused damage for country or car owner.

The purpose of this utility model is to provide a kind of motor tire pressure release detector that can find out automobile pressure release or deficency, and this detector can come out the pressure release state detection of tire, gives circuit processing such as report to the police.

Order of the present utility model is to realize by the represented technical scheme of accompanying drawing, it comprises a housing 12, outwards there is an edge housing upper end, on the edge, upwards be fixed with dividing plate 11 successively, rubber cup 3 that Open Side Down and the shell cap 1 that has joint, form an air-pressure chamber 2 between the rubber cup outside and shell cap, joint on the shell cap is used for being tightly connected with the valve inside of tire, there is a hole at the dividing plate middle part, be provided with a pressing plate 4 that has vertical rod downwards in the space that dividing plate and rubber cup form, vertical rod is inserted in the hole of dividing plate, fix one below the dividing plate and decide touch panel 5, decide to fix on the touch panel two contacts 6, respectively there is lead in housing, to draw on two contacts, a spring 8 is arranged in housing, the upper end of spring fix one with the movable contact spring 7 that can make two contact conductings after two contacts contact, the lower end of spring is fixed on the lower roof plate 9, in the bottom of housing an adjustable bolt 10 that can screw in the housing is arranged, the upper end of bolt withstands on the bottom surface of lower roof plate.When the utility model uses, need a high-pressure rubber pipe, one end of high-pressure rubber pipe and the joint screw thread on the shell cap are tightly connected, the other end of high-pressure rubber pipe and the valve inside of tire are tightly connected, and the valve of valve inside can be backed down, air pressure in the tire is connected with air-pressure chamber in the shell cap, and the interior pressure of the pressure in the air-pressure chamber and tire is identical.The lead of drawing on two contacts is used for connecting warning circuit.When in the air-pressure chamber pressure being arranged, pressure is depressed pressing plate, vertical rod under the pressing plate pushes contact downwards, and fixed touching plate is not contacted with movable contact spring, and disconnect two contacts, warning circuit is in off-state, when not having pressure or pressure to reduce to a certain degree in the air-pressure chamber, on the effect lower platen of spring, move, movable contact spring contacts with fixed touching plate, two contactings, the warning circuit conducting.

The utility model and circuit part thereof can be fixed on the spindle nose of detected tire, rotate synchronously with wheel, and warning device can adopt electric bell, are arranged on outside the car; Also can adopt other modes to be arranged in the car

The utility model is simple in structure, and cost is low, and is easy for installation, can know the disappointing situation of tire in time, is convenient to the driver and in time handles, and reduces the loss, and guarantees traffic safety.

Accompanying drawing is the utility model structural representation, and the expression air-pressure chamber is a passive state among the figure, and fixed touching plate contacts with movable contact spring.

Embodiment

As shown in drawings, housing is a jar shape, the cylinder of body is stamped to form by thick 2 millimeters steel plate, 16 millimeters of diameters, the body bottom is fixed at the bottom of the shell with screw, the upper end of body extrudes the limit of turning up, and dividing plate, rubber cup and the shell cap that will have fixed contact and pressing plate by bolt are fixed on the limit of turning up, and the joint on the shell cap has screw thread.1 millimeter of spring wire diameter in the housing, spring is cylindrical, 10 millimeters of diameters.The bolt of housing bottom is used for adjusting the atmospheric pressure value of warning.

Claims

1, motor tire pressure release detector, comprise a housing, outwards there is an edge housing upper end, it is characterized in that on the edge, upwards being fixed with successively dividing plate, rubber cup that Open Side Down and the shell cap that has joint, form an air-pressure chamber between the rubber cup outside and shell cap, joint on the shell cap is used for being tightly connected with the valve inside of tire, there is a hole at the dividing plate middle part, be provided with a pressing plate that has vertical rod downwards in the space that dividing plate and rubber cup form, vertical rod is inserted in the hole of dividing plate, fix one below the dividing plate and decide touch panel, decide to fix on the touch panel two contacts, respectively there is lead in housing, to draw on two contacts, a spring is arranged in housing, the upper end of spring fix one with the movable contact spring that can make two contact conductings after two contacts contact, the lower end of spring is fixed on the lower roof plate, in the bottom of housing an adjustable bolt that can screw in the housing is arranged, the upper end of bolt withstands on the bottom surface of lower roof plate.
