The specific embodiment
Need to prove, in the situation that do not conflict, embodiment and the feature among the embodiment in the utility model can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
Referring to Fig. 2, there is shown the preferred embodiment of the utility model remote control gate lock, this remote control gate lock is used for excavator.As shown in the figure, this remote control gate lock comprises lock body 7, the first gangbar 6 and dead lock 5 at least.
Referring to Fig. 2 and in conjunction with correlation technique as can be known, operated by rotary motion has dead bolt (not shown) and the first connector 71 on the lock body 7.The first end of the first connector 71 is connected with dead bolt, when the first connector 71 moves along above-below direction shown in Figure 2, can drive dead bolt and stretch out or be retracted to lock body 7, makes door-lock opening or closes.
As can be seen from Figure 2, an end of the first gangbar 6 is connected with the second end of the first connector 71, and the joint of the other end of the first gangbar 6 and dead lock 5 is affixed.People from this area should be appreciated that by remote-control key can control the flexible of dead lock 5 joints, and then drives the first gangbar 6, the first connector 71 corresponding actions, makes stretching out or being retracted in the lock body 7 of dead bolt.
The present embodiment makes the excavator door lock have distant control function by set up dead lock and the first gangbar at the excavator door lock, and is simple in structure, is easy to realize.
Preferably, the present embodiment can also comprise internal lock gangbar 4.Wherein, an end of internal lock gangbar 4 is connected with the second end of the first connector 71.Internal lock gangbar 4 is arranged in the driver's cabin, guarantees in the situation that dead lock 5 normal operations or malfunctioning can spur internal lock gangbar 4 from driver's cabin inside, to open and close door lock.
Preferably, above-mentioned remote control gate lock embodiment can also comprise tapered end pull bar 2, and an end of tapered end pull bar 2 is connected with the second end of the first connector 71, and the other end of tapered end pull bar 2 is used for being connected with the lockhole that is arranged at the driver's cabin outer wall.When key rotates in lockhole, can drive tapered end pull bar 2 action, the first connector 71 corresponding actions also can make door-lock opening or close.
During concrete operations, as shown in Figure 2, can internal lock gangbar 4, the first gangbar 6 and tapered end pull bar 2 be fixed on the second end of the first connector 71 simultaneously by steady pin 8.
People from this area should be appreciated that the first end that usually also is provided with the second connector 72, the second connectors 72 on the lock body 7 is connected with the first end of the first connector 71.When dead lock 5 release, the second connector 72 can drive 71 actions of the first connector, and then opens door lock.When dead lock 5 control door locks were closed, the second connector 72 can not drive 71 actions of the first connector, and at this moment, the second connector 72 can not be controlled door-lock opening.Syndeton between the first connector 71, the second connector 72 and the dead bolt is that people from this area is known, therefore do not give unnecessary details.
