Abstract

The utility model provides a deformation alarm for a car tyre, comprising a wheel provided contact connected with a buzzer via a conducting wire. The wheel arranging contact arranged on the drum plate of the inner side of the wheel drum of a wheel is formed by assembling a rotor switch, a rack body, a connecting lever, a clamping pipe, a contact bar, a return spring and an arranging and connecting seat. The switch spiral handle of the rotor switch and the connecting lever are connected into integration, a convex push shaft at the lower end side of the connecting lever is connected to the clamping pipe of the rack body, the clamping pipe is aslant downward pointed to the contact bar containing elasticity, and the rack body and the wheel drum are arranged and connected by the arranging and connecting seat. When the tyre is broken to leak air and deform, the contact bar is actuated to warn. The utility model has the advantages of flexible action, accurately, reliability, simple structure, easy manufacture and convenient operation.

Description

The automobile tyre deformation annunciator

The utility model relates to a kind of safety alarm device of Pneumatic vehicle tire, particularly the automobile tyre deformation annunciator.

Existing power actuated vehicle, particularly automobile, in case air-inflation tyre damages the gas leakage distortion under steam, wheel hub loses " air cushion " promptly can be impaired thereupon under heavy burden, and want seedling and axletree, car body and scratch road surface, and chaufeur but often is difficult in time discover.So, very harmful.Before this, though this type of warning device is also arranged,, fail to practice so adjustability, reliability and sensitivity are all relatively poor because its structure of contact terminal, feeler lever inclination angle and link gear coupling are unreasonable.

The purpose of this utility model is the defective at above-mentioned existing warning device, innovative design and a kind of assembling structure advantages of simple, attaching are provided and easy to use, be easy to regulate and be suitable for multiple vehicle and install and use, and have sensitivity, accurate, reliable and durable automobile tyre deformation annunciator, be social orientation.

Task of the present utility model is finished according to following technical proposals:

This automobile tyre deformation annunciator comprise buzzer phone, lead that city's pin is purchased, and the wheel of unique design is put contact.

The said wheel put contact and included roller actuator, support body, connecting lever, grip tube, feeler lever, retracing spring and the assembly of attaching seat and form, roller actuator is secured on the end plate face of flat board of support body, its switch swing handle is with the connecting lever upper end one of joining, connecting lever is coupling in the oblique body of the grip tube of finger down of support body with the protruding ejection of the side of lower end, feeler lever is held in the lower tube section culvert of grip tube, this feeler lever is the elastic body that wind spring or steel rope are made, and the attaching seat goes out, can be secured on the wheel wheel hub from the dull and stereotyped lower side of support body.

Distolateral revolving on protruding is equipped with set screw under the said connecting lever.

The body lower end of said grip tube is provided with tightening screw.

Said attaching seat system is formed by the base assembly of overbolt, clamp nut and rotation set.

City's pin commodity that used buzzer phone and roller actuator also are prior art in the technical program.

Advantage of the present utility model: buzzer phone is located at operator's compartment, wheel puts that contact is installed on the wheel wheel hub and lead links, and can in time conveniently discover the Pneumatic tyre wheel leakage fault; Wheel puts that contact is small and exquisite, the assembly coupling rationally, the feeler lever inclination angle is big and tool elasticity, flexible movements, preparation, reliable; Attaching seat and feeler lever adjustable length, easy for installation, can fit multiple vehicle wheel application; Buzzer phone and roller actuator are the product of prior art, and be reliability and durability; Integral structure is simple, be easy to manufacture, with low cost, be convenient to promote the use of.

Description of drawings of the present utility model:

Fig. 1 is an integral structure scheme drawing of the present utility model;

Fig. 2 is the schematic side view that wheel is put contact.

Among the figure: roller actuator 1, support body 2, switch swing handle 3, connecting lever 4, grip tube 5, base 6, clamp nut 7, bolt 8, side are protruding 9, set screw 10, retracing spring 11, tightening screw 12, feeler lever 13, lead 14, buzzer phone 15, binding post 16.

The utility model will elaborate in conjunction with the accompanying drawings and by embodiment.

This kind automobile tyre deformation annunciator is shown in attached Fig. 1 and 2: comprise that buzzer phone 15, lead and wheel put the contact assembly and form.It is taken turns and puts contact is to be formed for the major part assembly by roller actuator 1, support body 2, connecting lever 4, grip tube 5, feeler lever 13, retracing spring 11 and attaching seat.The positive and negative electrode binding post 16 that the buzzer phone 15 of city's pin is installed on operator's compartment and puts the roller actuator 1 in the contact with lead 14 and the wheel on being installed in the inboard wheel hub of wheel is connected.The support body 2 that wheel is put contact is a upper and lower rectangular flat plate that is respectively equipped with plate hole and has the side plate that side respectively goes out in the middle part.Roller actuator 1 is secured to the end of a dull and stereotyped side of support body 2, and its switch swing handle 3 is worn to join to other side and with the upper end that is the tabular connecting lever 4 of bar shaped that parallel shape controls with flat board from last plate hole and is integral.Support body 2 is pipe end on the transverse slat that this side side goes out is coupling grip tube 5, connecting lever 4 is with the side of its lower end protruding 9 body under grip tube 5 stage casings that reclines, on side protruding 9, also be provided with tapped aperture, attachedly screwed the ejection that ejection grip tube 5 realizes protruding 9 pairs of grip tube 5 bodys of side, be used for the inclination angle angle of grip tube 5 with a set screw 10.Feeler lever 13 is being held in the lower tube section culvert of grip tube 5, also is provided with one piece of tightening screw 12 in the pipe end place down at it.This tightening screw 12 is that one piece of warp-wise places grip tube 5 stomidiums, ailhead has the long-neck screw that one of spring 11 end that is reset colludes the revolved top locking feeler lever 13 of holding eyelet again.Feeler lever 13 is that a radicle stretches into the wind spring of the grip tube 5 and the clamping that is fixed or the elastic body that steel rope is made.Retracing spring 11 colludes the dull and stereotyped bottom aperture of hanger body 2 with other end, is used for tractive feeler lever 13, resets after making its swing.Attaching seat system is made of overbolt 8, the clamp nut 7 that is nested with and pipe box 6.Base 6 be secured on the clappers of the inboard axis hole of wheel hub bottom and spin wear from dull and stereotyped lower panel hole to overbolt install on wheel so that wheel is put contact.

The application of this automobile tyre deformation annunciator: as mentioned above it is installed on the automobile, the lower end of feeler lever 13 is regulated and is fixed on air-inflation tyre horizontal surface high position slightly.When tire is punctured by sharp sword or interior pressure increases when bursting, bleed a tire under the weight of car body distortion, wheel hub moves down and the feeler lever 13 of hypsokinesis contacted to earth, top connecting lever 4 turns of going towards, cause roller actuator 1 action and the circuit series that lead 14 connects buzzer phones 15 is communicated with, the warning of ringing of buzzer phone 15 in the operator's compartment, chaufeur can brake and repair or changing of tire, thereby avoids harm to enlarge.

The utility model not only is suitable for automobile to be installed, suitable equally for other pneumatic-tyred vehicle.
