Abstract

The utility model relates to a lock-control anti-theft anti-skid braking device which is an essential device for preventing the parked vehicle from being stolen and skidded. The lock-control anti-theft anti-skid braking device comprises a lock-control valve, a one-way valve, a pressure retaining device and a braking oil way; the opening and the closing of the lock-control valve are controlled through the positive rotation and the negative rotation of the key of the vehicle; the lock of the vehicle is connected with the lock-control valve; the lock-control valve is provided with an eccentric wheel; the lengthened core of the lock of the vehicle is connected with the axle of eccentric wheel; the axle of the eccentric wheel and an axial hole are sealed by a sealing ring; the eccentric wheel is matched with the one-way valve; the middle of the oil way is provided with the pressure retaining device which consists of an oil cylinder, a spring and a piston. When the lock-control anti-theft anti-skid braking device is used for braking the vehicle and releasing the breaking of the vehicle, the one-way valve is opened and closed through rotating the key of the vehicle to drive the core of the lock and the eccentric wheel to rotate. The utility model has the advantages of novel concept, advanced technology, simple structure and wide application range.

Description

The antitheft non-skid braking device of lock control

Affiliated technical field

The present invention is the antitheft non-skid braking device of various oil brakes.

Background technology

Present various vehicle is used parking brake when parking, both inconvenience was also dangerous.Though adopted various anti-theft measures, such as electronic lock, mechanical lock etc., the offender smashes vehicle window and utilizes the various utensils of unblanking to be easy to steal automobile, with prior art, the offender wants to open automotive lock and is difficult to, normally get around automotive lock and on circuit, juggle things, car engine is driven away.And this invention has just solved this difficult problem, has started automobile even get around automotive lock, because the brake that can't come loose, still have no idea automobile is stolen, unique method is destroyed brake fluid line exactly, and is so not only dangerous but also prolonged crime time, and the offender can think thrice before acting.Replaced hand brake device with high costs simultaneously, not only economy but also practicality have other lock incomparable advantage.

Summary of the invention

The objective of the invention is to design a kind of simple and practical antitheft non-skid braking device, utilize the hydraulic control principle with the vehicle pinning of when parking, braking, to strengthen antitheft simplification vehicle structure.

The present invention solves the concrete scheme that its technical matters adopts: this device is made up of Lock controlled valve (1), check valve (2), pressurizer (3) and brake fluid line (4) as shown in Figure 1, automotive lock and Lock controlled valve (1) connect together, Lock controlled valve has eccentric wheel on (1), automobile lock core and camshaft connect together, between camshaft and the axis hole seal ring is arranged, eccentric wheel cooperates with check valve (2), in the middle of the oil circuit pressurizer (3) is arranged, pressurizer (3) is made up of oil cylinder, spring and piston.

The invention has the beneficial effects as follows: novel, advanced technology, simple in structure, economical and practical, theftproof performance is superior, any oil brake all can reequip or install.

Description of drawings

Accompanying drawing 1 is a structure principle chart of the present invention.

The specific embodiment

During parking, pin touches on the brake, and turns off key, and brake fluid line is closed, and brake is in the antitheft anti-skidding state of pressurize.If brake weight is not enough, continue to step on brake, make brake solution pass through check valve (2) and continue toward the brake pressurization, with feel control brake pressure, the service brake that comes loose when pressure is suitable gets final product.

During driving, pin touches on the brake, and plays key, and brake fluid line is got through, the start a car service brake automobile that can drive away that comes loose.

Claims (2)

1, the antitheft non-skid braking device of lock control is made up of Lock controlled valve (1), check valve (2), pressurizer (3) and brake fluid line (4), it is characterized in that: automotive lock and Lock controlled valve (1) connect together, Lock controlled valve has eccentric wheel on (1), automobile lock core and camshaft connect together, the seal ring sealing is arranged between camshaft and the axis hole, and eccentric wheel cooperates with check valve (2).

2, according to the antitheft non-skid braking device of the lock control of claim 1, it is characterized in that: in the middle of the oil circuit pressurizer (3) is arranged, pressurizer (3) is made up of oil cylinder, spring and piston.
