Abstract
The utility model discloses an alarm for keeping the safety of driving truck, which comprises a power supply and a voice signal generator, and a rubber seal capsule is arranged between a gas pipe connector seat on a gas pipe connector and an alarm valve casing; a moveable valve with one end close to the rubber seal capsule is arranged in the alarm valve casing and connected with the alarm valve casing through a compression spring. When moving the valve, a current conductor arranged on the moveable valve contacts or does not contact a conducting contact on the alarm valve casing to switch on or cut off the alarming circuit. The utility model can effectively avoid the accidents caused by brake failure due to low truck braking air pressure with advantages of simple installation and practicality.
Description
Technical field
This utility model relates to a kind of braking warning device that is used for the autotruck safety traffic.
Background technology
The autotruck that is travelled in China various places, because the speed of a motor vehicle is fast, load carrying ability and moment of inertia are big, when emergency situation brakes, often, lead to serious traffic accident, cause great loss because the inflation pump of automobile and stop brake pressure are crossed low and caused brake failure.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, a kind of autotruck safety stop annunciator is provided, when the stop brake pressure of autotruck is lower than warning pressure, annunciator can sound the alarm, the prompting automobilist travels at a slow speed or stops to travel, when the stop brake pressure is higher than warning during pressure, annunciator is not worked, and makes the driver can safe cruising.
For achieving the above object, the technical scheme that the utility model is taked is: this annunciator contains power supply and voice signal producer, the rubber closed capsule is arranged between the gas-tpe fitting seat and annunciator valve housing on the gas-tpe fitting, be provided with in the annunciator valve housing end and rubber closed capsule near mobile valve, be connected with pressure spring between mobile valve and the annunciator valve housing, when mobile valve moves, be arranged on Ampereconductors on the mobile valve can realize be arranged on the annunciator valve housing on current contact contact or noncontact, thereby warning circuit is switched on or switched off.
This utility model effectively prevents and has avoided having simple, the convenient and practical characteristics of installing because the stop brake air of autotruck forces down the traffic accident that causes brake failure and cause.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described in further detail.
Rubber closed capsule 7 is arranged between the gas-tpe fitting seat 1 and annunciator valve body 2 on the gas-tpe fitting 6, tightens together by screw, gas that can the closed car gas circuit.Mobile valve 5 is installed in the annunciator valve housing 2, one end of mobile valve 5 is near rubber closed capsule 7, recessed portion at it is with pressure spring 10, and an end of pressure spring 10 connects the sidewall of mobile valve 5, and the other end connects the madial wall of annunciator valve housing 2.The other end at mobile valve 5 is equipped with Ampereconductors 12, and positive contact 3 and negative contact 4 are fixed on the front end place of annunciator valve housing 2 both sides, and positive contact 3 is connected with the positive pole of power supply 9, and negative contact 4 is connected with the negative pole of power supply 9 by voice signal producer 8.
The air pressure of automobile stop system enters valve chamber 11 through gas-tpe fitting 6, when air pressure is higher than warning pressure, pressure outwards expands rubber closed capsule 7, thereby making rubber closed capsule 7 promote mobile valve 5 outwards moves in annunciator valve housing 2, and then mobile valve 5 end place Ampereconductors 12 are not contacted with negative contact 4 with the positive contact 3 at the front end place of annunciator valve housing 2 both sides, thereby warning circuit is disconnected, and the driver can safety traffic.
When air pressure is lower than warning pressure, rubber closed capsule 7 bounces back inwards, mobile valve 5 reset movement inwards under the elastic traction of pressure spring 7, thereby Ampereconductors 12 is contacted with negative contact 4 with positive contact 3, warning circuit is connected, thereby voice signal producer 8 sends alerting signal, can remind the driver to take the measure of stopping or slowing down, and avoids brake failure to cause serious consequence.
Rubber closed capsule 7 can be selected the higher elastomeric material of oil resistant heatproof elasticity for use, and mobile valve 5 can select for use the wear-resisting withstand voltage nylon material of insulation to make, and Ampereconductors 12 uses the higher copper product of electric conductivity to make.
Claims (3)
1, a kind of autotruck safety stop annunciator, comprise power supply and voice signal producer, it is characterized in that, the rubber closed capsule is arranged between the gas-tpe fitting seat and annunciator valve housing on the gas-tpe fitting, be provided with in the annunciator valve housing end and rubber closed capsule near mobile valve, be connected with pressure spring between mobile valve and the annunciator valve housing, when mobile valve moves, be arranged on Ampereconductors on the mobile valve can realize be arranged on the annunciator valve housing on the contacting or noncontact of current contact, thereby warning circuit is switched on or switched off.
2, autotruck safety stop annunciator according to claim 1, it is characterized in that, described current contact is positive contact of electric current and the negative contact of electric current that is arranged on the annunciator valve housing, connects the anodal and negative pole that is connected power supply by the voice signal producer of power supply respectively.
3, autotruck safety stop annunciator according to claim 1 is characterized in that, described pressure spring is enclosed within the sidewall of described mobile valve recessed portion and end connection mobile valve, and the other end connects the madial wall of described annunciator valve housing.
