Abstract

The utility model discloses a vehicle brake anti-theft apparatus, which is characterized in that an oil-gas pipeline is provided with a valve core playing a role of anti-theft and is also provided with a non-return block with a spring, wherein, the non-return block is used for preventing backflow of the oil and the gas. When the vehicle stops driving and is braked, the braking oil-gas is unable to flow back, wheels of the vehicle is braked, and thus the purpose of anti-theft is attained.

Description

The automobile brake Car Burglar Alarm

The utility model relates to a kind of anti-joyride device, a kind of alarms and security systems for automobiles of saying so its body.

The anti-joyride device of present most of automotive uses is warning devices, promptly when the car stealer steals car, warning device just send toot ring, thereby the car stealer frightened away or caught.But some car stealer dismantled the circuit of alarm device earlier before stealing car, made warning device not bring into play effect.

The purpose of this utility model provides a kind of braking Car Burglar Alarm, and promptly the car stealer can't make the Car Burglar Alarm that wheel of the bus rotates.

Design plan of the present utility model is as follows: this braking Car Burglar Alarm is combined as a whole by an anti-theft column lock and a braking one-way control valve and constitutes, and can be installed in by the vehicle drive instrument, connects with oil, air brake piping.When chaufeur leaves automobile, use the key turns anti-theft lock, make one-way control valve be closure state.This moment, chaufeur was stepped on the braking automobile pedal, and whole wheels of automobile are braked securely, and the car stealer can't make one-way control valve be converted to unimpeded state under the situation that does not have the anti-theft column lock key, and automobile just can't be walked.

Characteristics of the present utility model are can prevent to steal the car incident effectively to take place, and use, install all very simple.

Below in conjunction with accompanying drawing the utility model is further explained:

Fig. 1 is the constructional drawing of the utility model automobile brake Car Burglar Alarm embodiment one.

Fig. 2 be Fig. 1 along A-A to cutaway view.

Embodiment 1:

The oil-feed, pore [1], [2] that connect automotive oil, air brake piping as can be known from Fig. 1 connect fuel-displaced, pore [3], [4] of wheel of the bus brake piping.A spool [6] is arranged on enclosure interior oil, tracheae line, also have a spring [5], a cover-plate type non-return stifled [7] that prevents that oil, gas from refluxing is arranged at spring [5] movable end.

As can be known from Fig. 2, spool leads to key hole one end pellet shot from a slingshot [8], and the other end has a plug [9] that prevents that spool from sliding.

When chaufeur is closure state with key with valve core rotation, step on brake pedal, brake solution, gas enter from oil-feed, pore [1], [2], promote spring [5], by fuel-displaced, pore [3], [4], enter the wheel braking pipeline then, and wheel of the bus is braked.After the braking automobile pedal was released, spring [5] set back very soon, and non-return stifled [7] prevents that oil, gas from refluxing.In that spool is changed into when unimpeded, can't remove the braking mode of wheel.When chaufeur changes spool when unimpeded into key, brake solution, gas reflux by spool, remove the braking mode of wheel.

Embodiment 2:

Difference from Example 1 is that stifled to become spherical non-return stifled with cover plate shape non-return, and all the other are all with embodiment 1.

Embodiment 3:

Difference from Example 1 is that the stifled bullet non-return that becomes of cover plate shape non-return is blocked up, and all the other are all with embodiment 1.

Claims

1, a kind of automobile brake Car Burglar Alarm comprises housing, anti-theft column lock, oil, air pipe, it is characterized by: a spool is arranged on enclosure interior oil, tracheae line, also have a spring, have a non-return that prevents that oil, gas from refluxing to block up at the spring movable end.

2, a kind of automobile brake Car Burglar Alarm as claimed in claim 1 is characterized by, and spool leads to key hole one end pellet shot from a slingshot, and the other end has a plug that prevents that spool from sliding.
