Abstract
The utility model discloses a low-pressure warning device for tyre, which has the advantages of simple structure, small physical dimension and long battery service life and does not influence the tyre to be normally used when the low-pressure warning device for tyre is unladen. The low-pressure warning device for tyre comprises a cell box body, a top cap, a convex rubber pad, an upper cover, a screw nut, an electrode screw nut, a transmitting circuit providing box, an emitting and receiving circuit. The lower inner wall of the cell box body is inlaid with the electrode screw nut and the screw nut. A seal pad, the top cap and the convex rubber pad are installed in the lower box cavity. The upper inner wall of the cell box body is inlaid with the electrode screw nut. The upper cover with a top spring is screwed on the electrode screw nut. The outer box wall of the cell box body is provided with the transmitting circuit providing box. The utility model can be used in various low-pressure warning devices for tyre.
Description
Technical field:
The utility model relates to the Pressure monitoring technical field, and specifically it is a kind of tire infrabar annunciator.
Background technology:
It is one of vehicle safety, the prerequisite condition of cruising institute that tire keeps certain air pressure, and it generally all is to measure with air-pressure gauge when inflation of tire that air pressure detects, and this method is easy to realize; But the reduction of tire pressure often all produces when travel condition of vehicle.If vehicle is when running at high speed, tire is punctured, and the tire internal gas pressure sharply descends, and often grinds bad tire in the short time at the utmost point, even causes serious traffic accident; In addition, tire is worked under the infrabar state for a long time, also very easily causes tire failure.So the air pressure of dynamic monitoring tire just seems even more important in the vehicle ' process.Chinese patent 92107287.2 disclosed alarm device for tyre pressure, be with originally in the tire valve inflate, sealing arrangement all removes, outside reporting to the police when alarm device for tyre pressure degasification pressure drop is low, also increased inflate, sealing arrangement, sinuflo tube produces distortion under the effect of pressure, drive moving contact and contact with break back contact or separate, in case this structure warning device damage or when not using, tire just can not independently be inflated use again; And volume is also relatively large.
Summary of the invention:
The purpose of this utility model just provide a kind of simple in structure, physical dimension is little, the battery long service life, do not influence the normal tire infrabar annunciator that uses of tire.
The purpose of this utility model is to realize like this, tire infrabar annunciator comprises battery box, the top cap, the convex rubber cushion, loam cake, nut, the electrode nut, the transmission circuit mounting box, transmit and receive circuit, it is characterized in that: setting-in electrode nut (13) and nut (9) on the lower inner wall of battery box (8), packing seal (12), top cap (11) and convex rubber cushion (10) are installed in the lower box chamber, setting-in electrode nut (6) on the upper inside wall of box body (8), the loam cake (4) that has top spring (5) is screwed on the electrode nut (6), on the outer box wall of battery box (8), be provided with transmission circuit mounting box (2), the upper surface of transmission circuit mounting box (2) is provided with indicator lamp mounting hole (3), and bottom (1) is equipped with in the bottom.
Compared with prior art, structure of the present utility model is simpler, the powered battery mode design science, simple and direct, after all parts and transmission circuit were assembled into finished product, system did not work, and is convenient to shelve for a long time as commodity.When tire pressure when rated value is above, circuit is in mode of operation, but not conducting of circuit, so prolonged the service life of battery.In addition, when not using the utility model, as long as it is taken off, tire still can with the same normal use originally.

Fig. 2 is the utility model electrode nut part figure.
Fig. 3 is the scheme drawing of the utility model acceptor circuit mounting box.
Fig. 4 is a transmission circuit reference diagram of the present utility model.
Fig. 5 is an acceptor circuit reference diagram of the present utility model.
The specific embodiment:
Embodiment 1:
Nut 9, electrode nut 13 and electrode nut 6 adopt the conductor metal material, make as copper, and transmission circuit is installed in the transmission circuit mounting box 2, and with bottom 1 capping, the positive and negative electrode of circuit links with the positive and negative electrode nut respectively; The warning acceptor circuit is fixed in the mounting box 16, is installed on the interior a certain suitable position of operator's compartment again.Compact battery 7 is put into battery box 8, and loam cake 4 is tightened on the electrode nut 6, because of UNICOM not between electrode nut 13 and the nut 9, so transmission circuit is not still worked behind the battery of packing into; After annunciator was screwed on the cranked tire valve 15, the valve 15 of conductive material was with electrode nut 13 and nut 9 UNICOMs, and transmission circuit is started working, and alarm equipment alarm, indicator lamp are lighted, and prove that whole warning is working properly, otherwise, should overhaul; Along with annunciator and valve 15 are tightened gradually, top cap 11 is depressed the gaseous core bar 14 of valve 15 gradually, gas in the tire releases, convex rubber cushion 10 is heaved and the elastic force that overcomes spring 5 pushes away nut 9 with the negative pole of battery 7 to the battery direction under the effect of air pressure, annunciator stops to report to the police, indicator lamp extinguishes, and annunciator enters mode of operation.When tire flat, when the tire internal gas pressure is lower than rated value, battery 7 is negative pole and nut 9 connections under the elastic force effect of spring 5, and annunciator begins to report to the police, maintenance of prompting chaufeur or changing of tire.When annunciator was loosening because of certain reason produces, gaseous core bar 14 resetted, and guarantees that tire can not leak gas; Simultaneously, annunciator begins to report to the police, and the prompting chaufeur is tightened annunciator.
Consider the shielding action of self-propelled vehicle metal car body, the receiving wire 17 of acceptor circuit can adopt the flexible metal lead, extend be installed to annunciator near.
At present, the kind of emission, acceptor circuit has a lot, and the utility model provides transmits and receives circuit, reference during only for use.
