Abstract
The utility model relates to an induction plug for tire pressure alarms, which comprises an inflating valve 1 and a plastic back sleeve 2. The plastic back sleeve 2 is screwed on the side of the inflating valve 1 which is not connected with the tire admission piece; a gasket 9 and a rubber piston 3 are arranged in the inflating valve 1; the rubber piston 3 is connected with one end of a spring 5 positioned in the back sleeve 2 through the metallic push rod 6; the other end of the spring 5 is contacted with an adjusting screw 4. The inflating valve 1 and the push rod 6 form a signaling switch, wherein, one end of the signaling switch is connected with the earth, and the other end is connected with an emitter. The utility model has the advantages that the air can not be leaked easily with the induction plug and the pressure in the tire can be adjusted automatically.
Description
Technical field
The utility model relates to a kind of induction plug of motor tire annunciator.
Prior art
Chinese patent " tire pressure alarm " discloses a kind of tire pressure alarm, is made up of transmitter and receiver.Emitter is installed on the autotruck wheel hub, and receiver is located in the operator's compartment.Baroswitch is arranged on the emitter, be connected with the inflation of tire mouth by air hose.This product is used to monitor tire pressure.When low tyre, the baroswitch closure is connected warning circuit, sends alerting signal and gives receiver, reminds driver's on-call maintenance, avoids the bad or explosion of rubber-tyred roller, with the generation that reduces economic loss or avoid traffic accident.The signal of this annunciator is produced by baroswitch, and baroswitch links to each other with the inflation of tire mouth by air hose, should report to the police like this to have the many problems of gas leakage point, and when the tire internal gas pressure was too high, tire also can not get protection.
Technical scheme
The purpose of this utility model provides a kind of induction plug of motor tire annunciator.
The technical solution of the utility model is achieved in that a kind of tire pressure alarm induction plug of design, it comprises after valve connects mouth and plastics overlaps composition, back external threading is connected valve and connects the non-end that combines with the tire admission piece of mouth, packing seal and rubber piston in connecing mouth, valve are arranged, rubber piston contacts by the interior spring of push rod and back cover, valve connects mouth and push rod forms signal switch, and an end of switch joins with ground, and the other end and projector join.
This induction plug also can be designed to: it comprises after valve connects mouth and metal overlaps composition, back external threading is connected valve and connects the non-end that combines with the tire admission piece of mouth, packing seal and rubber piston in connecing mouth, valve are arranged, rubber piston contacts by the interior spring of push rod and back cover, between push rod and spring, insulating barrier is arranged, valve connects mouth and push rod forms signal switch, and an end of switch joins with ground, and the other end and projector join.
Connecing at the valve of above-mentioned induction plug has tire admission piece valve inside push rod in the mouth; Connecing at valve has on the mouth and air bleed hole; One end of spring is contacted with adjusting screw(rod); Signal switch is directly to join with projector, and also available electric wire separately joins.
The utility model has only valve to connect mouth and tire joins, and contact point is few, then is difficult for gas leakage; On induction plug, be provided with air bleed hole, but when the tire internal gas pressure is too high automatically regulating tire internal gas pressure.
Description of drawings
Fig. 1: the product structure scheme drawing that overlaps behind the utility model band plastics.
Embodiment
Fig. 1 is the product structure generalized section of overlapping behind the utility model band plastics, the utility model comprises that the metal valve connects behind mouth 1 and the plastics cover 2 and forms, back cover 2 is threaded in valve and connects mouth 1 a non-end that combines with the tire admission piece, rubber gasket 9 and rubber piston 3 in connecing mouth 1, valve are arranged, spring 5 one ends that rubber piston 3 overlaps in 2 by metal pushrod 6 and back contact, and the other end of spring 5 and adjusting screw(rod) 4 are contacted.Valve connects mouth 1 and forms signal switch with push rod 6, and an end of switch joins with ground, and the other end and projector join.Tire admission piece valve inside push rod 8 is arranged in valve connects mouth 1 and be used to arrange and cross anticyclonic air bleed hole 7 in the tire, when air pressure is too high, rubber piston 3 moves to spring 5 directions, expose air bleed hole 7 and discharge a part of gas, when when requiring (tension force by spring 5 is determined) to air pressure, spring 5 resets piston 3 by push rod 6, closes air bleed hole 7.Signal switch is to join by the electric wire and the projector (not shown) of joining with push rod 6.Certainly, signal switch also can directly join with projector, and receiving device is placed in the operator's compartment.
The another kind of embodiment of the utility model is compared with aforesaid way, and different is: its back cover 2 is metallo-s, between push rod 6 and spring 5 insulating barrier is arranged, and communicates in order to avoid signal switch directly connects mouth 1 with valve.
