In order to overcome the deficiency of background technology, the invention provides a kind of expansion brake lock, solving when existing expansion brake lock pins self-propelled vehicle and need be inserted into line operate with key, inconvenient problem with use.
The technical solution adopted in the present invention: a kind of expansion brake lock, comprises housing, is provided with lock core, lock, push pedal, cam, button in housing, described push pedal comprises base plate and the first side plate, the second side plate perpendicular to base plate two ends; Described lock core one end is connecting portion, and the other end is the socket of key; Described cam center position is provided with mesopore, and the connecting portion of described lock core inserts in mesopore, and described lock core can be pressed certain angle and rotate in mesopore; Described cam is also provided with the elastic element that can make cam return; Described base plate has chute, and described cam is provided with fixture block, and fixture block is placed in chute; Described chute is provided with the buckling groove with fixture block clamping; The first described side plate is connected with lock; The second described side plate is provided with Flexible Reset mechanism; Described button is corresponding with the position of the second side plate.
Described mesopore be two crossing fan-shaped, shape is in shape with a tight waist.
Described push pedal is U-shaped.
Described Flexible Reset mechanism is retracing spring, between the second side plate and lock core.
The first described side plate has semicircle opening, and described lock and semicircle opening clamping, be provided with lock pull back spring between described lock and lock core.
Described elastic element is torque spring.
Described button is provided with button pull back spring.
Lock cover and locking closure is provided with outside described lock core.
The invention has the beneficial effects as follows: adopt above scheme, only need promote button, just can drive push pedal, released by lock, cam rotates under the effect of elastic element simultaneously, makes fixture block and the clamping of buckling groove phase, make expansion brake lock be in locking-in state, just can pin self-propelled vehicle, operation is very easy.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated:
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, a kind of expansion brake lock, comprises housing 1, is provided with lock core 2, lock 3, push pedal 4, cam 5, button 7 in housing 1, described push pedal 4, in U-shaped, comprises base plate 41 and the first side plate 42, second side plate 43 perpendicular to base plate 41 two ends; Described lock core 2 one end is connecting portion 21, and the other end is the socket of key; Described cam 5 centre is provided with mesopore 52, the connecting portion 21 of described lock core 2 inserts in mesopore 52, described mesopore 52 be two crossing fan-shaped, shape is in shape with a tight waist, described lock core 2 can be pressed certain angle and rotate in mesopore 52, when after unblock, key can be adjusted to appropriate location, be convenient to key and extract; Described cam 5 is also provided with the torque spring that can make cam return; Described base plate 41 has chute 411, and described cam 5 is provided with fixture block 51, and fixture block 51 is placed in chute 411; Described chute 411 is provided with the buckling groove 412 with fixture block 51 clamping, and when being in locking state, fixture block 51 is connected in buckling groove 412, can keep locking-in state;
The first described side plate 42 has semicircle opening 421, and described lock 3 and the clamping of semicircle opening 421, be provided with lock pull back spring 9 between described lock 3 and lock core 2, conveniently can adjust the state position of lock 3;
Described button 7 is corresponding with the position of the second side plate 43, when needs pin, promotes button 7 and just can promote the second side plate 43, drive push pedal 4, just can pin;
Be provided with retracing spring 8 between the second described side plate 43 and lock core 2, when needs unlock, lock core 2 turns round, and make fixture block 51 leave buckling groove 412, retracing spring 8 just can push push pedal 4 open, makes it to unlock.
Be provided with lock cover 11 and locking closure 12 outside described lock core 2, described lock cover 11 and locking closure 12 can prevent silt etc. to enter lock core 2, play certain protective effect to lock core 2.
