Description
Technical field
The utility model relates to a kind of fixing lock for self-locking car emergency brakes.
Background technology
At present, vehicle under steam, especially descending time, have report when running into brake failure or the out of control and traffic accident caused, especially the traffic accident that causes of heavy goods vehicle and oversize vehicle is even more serious, and great majority are major accidents of car crash.
For the problems referred to above, someone proposes various solution, but for the fixing lock of car emergency brakes in prior art, can only use light-duty or pony car, when high capacity waggon uses, run into and jolt, lock body is easily thrown off, and causes severe compromise, firm to lock, unblanks and inconvenient.
Summary of the invention
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of fixing lock for self-locking car emergency brakes.
The utility model is achieved by following technical solution: a kind of fixing lock for self-locking car emergency brakes, comprise lock housing, first lock core, second lock core, pin, spring, leaf spring, lock pull bar and lock cap, the lock cap that lock housing top connects is bolted in the base cross members of automobile frame, the pin fastener of lock housing two sides by running through, respectively by bearing pin, the first lock core and the second lock core are installed in the opening both sides of lock housing bottom, mounting spring between first lock core rear end and lock housing, between second lock core lower end and lock housing, leaf spring is installed, first lock core front end is blocked by the step of the second lock core under the action of the spring, make locked object part can not depart from fixing lock in the U-lag of the first lock core front end, second lock core upper end is also provided with lock pull bar, during brake hard, pull lock pull bar to make the second lock core stir the first lock core around bearing pin rotation to rotate around bearing pin simultaneously, second lock core just loses the constraint to the first lock core when turning over certain angle, discharge by the object locked, and locked object part departs from fixing lock by the downward landing of deadweight.
This fixing lock for self-locking car emergency brakes that the utility model proposes, possesses following advantage:
1. reliability is high, and locked object body can not be deviate from from lock;
2. unblank convenient light and handy, only need pull bar be pulled by less power just can to unlock.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is assembling view of the present utility model;
Number in the figure is: 1-lock housing, 2-pin, 3-first lock core, 4-leaf spring, 5-lock pull bar, 6-spring, 7-second lock core, 8-lock cap.
Detailed description of the invention
Below in conjunction with accompanying drawing 1-2 and embodiment, the utility model is described in further detail.
Fixing lock for self-locking car emergency brakes of the present utility model, its structure mainly comprises lock housing 1, first lock core 3, second lock core 7, pin 2, spring 6, leaf spring 4, component such as lock pull bar 5, lock cap 8 etc.Assembling drawing, structure are as shown in accompanying drawing 1-2.Lock cap 8 is bolted on support, and during installation, lock cap 8 is upper.Locked object body is entered in the U-lag of the first lock core 3 by the opening of lock housing 1 bottom and drives the first lock core 3 to rotate around bearing pin, and simultaneously the first lock core 3 is stirred the second lock core 7 and rotated clockwise around bearing pin.Now locked object body has the trend that drive first lock core 3 rotates clockwise around bearing pin under self gravitation effect, but the first lock core 3 is blocked by the step of the second lock core 7, makes to be locked weight and can not depart from fixing lock and reach locking object.
When needing release locked object body, only the second lock core 7 just can need be made to rotate around bearing pin to lock pull bar 5 pulling force applied to the right, just lose the constraint to the first lock core 3 when the second lock core 7 turns over certain angle, weight is released under self gravitation effect.
