Abstract

The utility model discloses an improved tyre protection inductor, which belongs to tyre protectors. The utility model is used for generating alarm signals in time to avoid the damage of a tyre when the tyre pressure is insufficient. The tyre protection inductor is composed of a shell and a revolving body, the pin shaft fixed to the center of the revolving body is extended out of the shell, and a revolving lever is fixed on the top of the pin shaft. When the tyre pressure is insufficient, the revolving lever is rotated under stress, and a contact point in the inductor is connected with a circuit to generate audible and visible signals. When the external force is removed, the revolving lever can be reset automatically, and the revolving lever can also be in the horizontal position when necessary. The utility model is suitable for various automobiles and trailers and avoids the abnormal damage of the tyre caused by the insufficiency of tyre pressure.

Description

A kind of improved tire protection inductor

A kind of improved automobile tyre protection inductor, it belongs to a kind of apparatus for protecting tyres.

All types of power actuated vehicles in current operation, the accident of damaging tire because of the backing of air pressure deficiency is recurrent, the patent application of more existing apparatus for protecting tyres, still fruitful application is seen at the end.The ZL95208552.6 utility model patent " automobile tyre protection inductor " that on February 25th, 96 authorized; its structural principle is when low tyre; inductor reduces the height kiss the earth; the inductor revolution; expansion link is compressed; the both has the contact that alarm circuit is connected, and makes annunciator send alerting signal.Have the little steel rope of spring traction to make it recover the upright position on the gyro-rotor, expansion link resets by spring thrust.The part of this device is more, and processing and manufacturing difficulty is big, and its structure also can more be simplified.

The purpose of this utility model is to simplify its project organization on the basis of ZL95208552.6 patent, makes the tire protection inductor be easier to processing and fabricating satisfying under the condition of in-use performance.

The technical scheme of this protection inductor is such: inductor is fixed on the wheel shaft; the gyro-rotor that is installed in the housing fuses by the fulcrum post outside bearing pin and the housing, when low tyre, highly descends; the fulcrum post kiss the earth is subjected to the counter-force effect and produces revolution.

Gyro-rotor has a contact with two interplanars that housing faces mutually, and it links to each other with alarm circuit, and the normal circumstances lower contact is in the insulation off-state, and stagger the insulation position and the circuit connection is reported to the police in the contact when gyro-rotor rotates.

Garden, location arc breach is arranged on the gyro-rotor, be pressed in roller on the arc breach of garden, the location is arranged and make gyro-rotor rotate the back reset response by spring.

The structure of this protection inductor is simpler than ZL95208552.6 patent structure, has reduced the part of flexible warning, has changed structure that little rope traction resets and part is reduced and has been easy to processing.Therefore reduce production costs and commodity price, be easier to be accepted and popularization as early as possible by the user.

Fig. 1 is the constructional drawing of tire protection inductor

Be described further below in conjunction with accompanying drawing, the protection inductor shown in the accompanying drawing 1 is fixed by bolts to the position of automobile axle axle near tire by cover plate (1), make pivoted lever (13) built on stilts one segment distance of inductor.When low tyre, the wheel shaft height descends, and surpasses after the safety distance pivoted lever kiss the earth, stressed revolution backward.Gyro-rotor (8) top is cut into the plane, and arc notch is arranged in the middle of the plane, and roller (7) is by wedge (6), and spring (4) is pressed on the breach.Gyro-rotor joins together by the pivoted lever of bearing pin (12) screw (5) with the housing outside, and gyro-rotor overcame the spring pressure of roller and rotation simultaneously when pivoted lever rotated.

Housing (3) is made by insulating material, and facing mutually with gyro-rotor (8) has induction warning circuit contact in the plane, and steel ball (10) is arranged in the housing inner plane aperture and little spring (9) that lead (2) links.Be inlaid with collets (11) in the aperture of the corresponding gyro-rotor of steel ball plane, gyro-rotor rotates and to make steel ball miss the insulation position to contact and the conducting alarm circuit with the metal part branch of gyro-rotor.Fault is eliminated the back gyro-rotor and is automatically reset under spring (4) effect.

For adapting to the vehicle different situations, it is adjustable that pivoted lever (13) is gone up height at bearing pin (12).The pivoted lever middle and lower part is the bending certain angle backward, makes earth point depart from the distance in gyro-rotor center.The pivoted lever lower end is the garden arc to the back upper place bending.

There is the camber breach in the garden of gyro-rotor horizontal diameter on all positions, when automotive servicing maintains, pivoted lever can be rotated 90 degree and be fixed on level attitude, closes alarm switch.

Above working process has provided an embodiment of tire protection inductor, and different automobile types can be made into different size.
