Abstract
The utility model discloses a tire low pressure alarm which comprises an emitting device, a receiving device and a switch device. The tire low pressure alarm is characterized in that the switch device is arranged on a wheel hub, and the upper part of a switch body is provided with a through hole, the inside of which is provided with a sensing element which can carry out reciprocating motions. The inside of the switch body is orderly provided with an insulating mat, a spring and a fixed cover, the upper surface of the insulating mat is provided with a conduction contact point, and the conduction contact point and the fixed cover are respectively connected with a conducting wire. When the air pressure in an inner tire of two tires is lower than the set air pressure or the inner tire of two tires has no air, the conduction contact point on the insulating mat contacts the switch body under the action of the spring and transmits the information to the emitting device, a signal light and a buzzer of the receiving device arranged in the cab send out signals, and the driver can take measures in time to prevent the occurrence of accidents. The tire low pressure alarm is applicable to lorries, passenger buses and large and medium trucks.
Description
Technical field
The utility model relates to a kind of tire low pressure alarm.
Background technology
The rear axle both sides of the full size vehicle in the communications and transportation are made as two-wheel; When an inner tube of a tyre in two wheels does not have gas, will the load of another wheel be strengthened, and the driver and conductor be difficult for realizing, usually causes safety misadventure.At present the way of taking precautions against is: at set intervals or beat wheel behind the walking certain distance with check inner tube of a tyre barometric information.Its shortcoming is that operation is loaded down with trivial details, the pressure condition of tyre cavity in can not grasping at any time.
The utility model content
The purpose of this utility model is to design a kind of tire low pressure alarm of being made up of switch body, sensing part, insulating mat, spring, conductive contact, fixed cap and seal ring for overcoming above-mentioned deficiency.
The utility model is achieved in that a kind of tire low pressure alarm, comprises feedway, receiving device and switching device, and described switching device is loaded on the wheel hub, and switch body top is provided with through hole, and reciprocating sensing part is housed in the through hole; Insulating mat, spring and fixed cap are housed in the switch body successively; The upper surface of insulating mat is provided with conductive contact, respectively is connected with lead on conductive contact and the fixed cap.
The top of described switch body is provided with the wing dish, and flat horizontal surface is cut in being provided with of the side symmetry of wing dish, and two cut the width that distance between flat horizontal surface is slightly smaller than the inner tube of a tyre air inlet pipe tube seat on the wheel hub.
Described switch body lower end is provided with screw thread, and fixed cap and switch body are through being threaded or being welded to connect.
The axle of described switch body and sensing part is provided with seal ring.
Described feedway is loaded on the axle head of automobile hind axle.
Load onto the tire low pressure alarm and to after the inner tube of a tyre inflation, sensing part promotes insulating mat under the effect of air pressure, spring moves down and compression spring when the two-wheel on the automobile hind axle, conductive contact leaves the switch body surface, and electric loop disconnects.The emitter no signal is sent.Insulating mat is under action of the spring when the air pressure of the inner tube of a tyre is lower than setting air pressure or does not have gas, conductive contact contacts with switch body, by lead information is reached feedway, the signal lamp and the buzzer phone that are loaded on the receiving device in the operator's compartment send signal, the driver and conductor can in time take measures, and accident prevention is in possible trouble.In addition, when the utility model was installed, elder generation cut the air inlet pipe tube seat of the inner tube of a tyre on the flat horizontal surface aligning wheel hub to two of the upper fin of switch body and pushes, and revolved to turn 90 degrees again, and the tire low pressure alarm is fixed under the gas pressure of interior tyre cavity, simple installation.

Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the fixed cap and the switch body connection diagram of another kind of form.
The specific embodiment
The tire low pressure alarm is made up of sensing part 1, switch body 2, conductive contact 3, copper sheathing 4, spring 5, fixed cap 6, lead 7,8, insulating mat 9 and seal ring 14.Referring to Fig. 1, Fig. 2.Switch body top is provided with through hole, and reciprocating sensing part is housed in the through hole; On the sensing part axle, be provided with seal ring 14, insulating mat, spring and fixed cap are housed in the switch body successively; Switch body and fixed cap are through being threaded, and the upper surface of insulating mat is provided with conductive contact, and present embodiment is equipped with copper sheathing 4 on insulating mat, annotate tin in copper sheathing, and is connecting lead 8; On insulating mat, form conductive contact, be welded with another root lead 7 on the fixed cap by tin; The top of switch body is provided with two wing dishes.Distance between two wing dishes should be greater than the wall thickness of wheel hub; The both sides of superposed wing dish are provided with the flat horizontal surface 12, two of cutting of mutual symmetry and cut the width that distance between flat horizontal surface is slightly smaller than the inner tube of a tyre air inlet pipe tube seat on the wheel hub 10.After the two-wheel on the automobile hind axle was loaded onto the tire low pressure alarm and given the inner tube of a tyre 11 inflations, sensing part promoted insulating mat under the effect of the air pressure of the inner tube of a tyre, spring moves down and compression spring, and conductive contact leaves the switch body surface, and lead 7,8 is electrically connected and is disconnected.The feedway no signal is sent.Insulating mat is under action of the spring when the air pressure of the inner tube of a tyre is lower than setting air pressure or does not have gas, and conductive contact contacts with switch body, and circuit is connected, and emission is hit device and transmitted; The receiving device that is loaded in the operator's compartment is received signal, and its signal lamp and buzzer phone send signal, and the driver and conductor can in time take measures, and prevents accident, guarantees safety.Fig. 3 is another kind of version, and its fixed cap 13 is welded in the lower end of switch body.Feedway of the present utility model and receiving device are
Prior art.
