Abstract
A tyre low-pressure alarm is characterized in that a shell is arranged on the alarm. A connector which is connected with an inflating mouth of tyre is arranged on tail end of the shell. A middle empty air chamber is arranged inside the shell. A narrow air way is arranged between the connector and the air room. An air valve base which is a closed connecting member is arranged on the top of the shell. A vent-hole which is communicated with the air chamber is arranged in the center of the connecting member. The vent-hole of the air valve base is designed into two sections of wide and narrow. A spring part which is arranged in axial direction in the air chamber is arranged on the wide section of the vent-hole. A valve inside is arranged on the end of the spring along the connector direction. An alarm device is connected with the air valve base. The alarm device has a simple structure and convenient use, therefore, which can reach the aim of efficiency alarm to expand applications.
Description
The utility model relates to a kind of automotive alarming device, and what relate to specifically is a kind of tire low pressure alarm.
Automobile is under steam owing to be subjected to influence of various factors (as top shake, wear on tyres etc.), cause the damage of the inner tube of a tyre and cover tire easily, to making tire flat, less because of leaking gas again sometimes, chaufeur is difficult to grasp and find in the way of travelling, and time one length very easily causes the accident.The solution of taking at present just like: under vehicle rear axle the peace one spring, a contact is arranged on overhead certain distance, single line leads to operator's compartment, connect an annunciator in the operator's compartment, when tire flat to a certain degree the time, kiss the earth below the spring, top contacting, and reach the operator's compartment warning; Also just like two steel discs being set under rear axle, when tire flat to a certain degree the time, tire sinks, steel disc mops floor and makes sound and make chaufeur vigilance to some extent.More than these measures though certain effect is arranged because travel situation complexity, add heavy duty, so DeGrain with unloaded different.And use this mode of contact, and also can be of a specified duration because of the contact period of service, dust, rainwater soak turbid getting rusty and cause contact failure.
The purpose of this utility model is in order to solve above-mentioned the deficiencies in the prior art part, and providing a kind of can effectively report to the police, tire low pressure alarm simple in structure, easy to use.
For achieving the goal, the utility model provides following technical solution:
A kind of tire low pressure alarm, it is characterized in that: this annunciator is provided with a housing, be provided with tire at the housing tail end and add the interface that gas port links to each other, enclosure interior is a hollow gas chamber, and the housing top is provided with the valve valve and sits, and it is a sealing attaching parts that the valve valve is sat, be connected with the air extractor vent that communicates with air chamber in the middle of it, be provided with the spring of axial placement in the air chamber, the spring terminal of interface direction is provided with valve inside, sits with the valve valve and is provided with warning device mutually.
Feature of the present utility model also is also to be provided with between interface and the air chamber narrow and small air flue.
Feature of the present utility model is that also the air extractor vent that described valve valve is sat can be made as two sections of width, and spring section places in the wide section air extractor vent.
Feature of the present utility model is that also it is a separate component that described valve valve is sat, and the valve valve is sat and is threaded with housing.
Feature of the present utility model is that also described warning device can be the electric induction type annunciator, also can be the hummer of pneumatic type.
The utility model need not to dismantle annunciator when retread a tyre, gas-adding pipe directly can be inserted in aerating on the hummer, when reaching required air pressure, falling gas-adding pipe, inner pressure of tire shrinks spring, valve inside closes air extractor vent, tire occurs and break in the tire running process, produces gas leakage and cools down slowly, make and force down in the tire when safety air pressure, the tire internal gas pressure reduces, and the pressure that spring is subjected to also reduces, thus recovery of elasticity, and make valve inside open air extractor vent, gas passes through air flue in the tire, pore agitates hummer to send the sound, and chaufeur can be judged according to sound, looks for safe location parking maintenance immediately.
Accompanying drawing is a STRUCTURE DECOMPOSITION scheme drawing of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in the figure, tail end at annunciator housing 5 has the interface 10 that connection adds gas port, connect the interface that adds gas port and be provided with tightening seal washer 9, in the housing 5 is hollow gas chamber 7, it between air chamber 7 and interface 10 narrow and small air flue 8, be connected with detouchable sealing attaching parts valve valve on the top of housing 5 and sit 3, in the middle of sitting 3, opened by the valve valve pore 2, air extractor vent 2 is divided into two sections of width, spring 4 parts that axially are positioned in the air chamber 7 place in the wide section pore 2, be connected with valve inside 6 on the spring 4 of interface 10 directions, the valve valve is sat 3 outer ends and is connected hummer 1.
During use, remove the former tire that is contained in and add valve inside in the gas port, annunciator is contained in adds the gas port place, gas-adding pipe is aerating on hummer 1 directly, in the aerating process, spring 4 is positioned at air chamber 7, after being added to safe air pressure, stop aerating, at this moment, because the effect of tire internal gas pressure enters in the wide section air extractor vent 2 of valve valve seat 3 spring 4 compressions, the valve inside 6 on the spring 4 is with air extractor vent 2 sealings, tire is air tight, but cruising.
Work as rupture of tire, produce gas leakage, when cooling down slowly, tire internal air pressure reduces gradually, if when being lower than safe air pressure, spring 4 recovers, and valve inside 6 is opened air extractor vent 2, gas is discharged by air flue 8, air extractor vent 2 in the tire, and agitates hummer 1 to send the sound, and chaufeur promptly obtains alarm.Safety factor when the annunciator of this structure can increase the chaufeur driving, thereby the generation of minimizing traffic accident.
