By the description referring to accompanying drawing, above and other feature and advantage of the present utility model will become easier to understand, in accompanying drawing:
Fig. 1 is according to the schematic diagram when vehicle door lock device of the utility model one embodiment is on the door body being installed on driver's cabin;
Fig. 2 is the stereogram of the vehicle door lock device shown in Fig. 1 when seeing inside door body;
The stereogram that Fig. 3 is the vehicle door lock device shown in Fig. 1 viewed from the external side of door time.
Detailed description of the invention
In further detail the utility model is described below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, be installed on the door body 10 of driver's cabin according to the locking device for cab door of the utility model one embodiment, more specifically, be installed on the inner side of a body 10.Particularly as can be seen from Figures 2 and 3, first control device 11, first connector 12, first locking mechanism 13, second connector 14, second locking mechanism 15, second control device 21 and the 3rd connector 22 is comprised according to the locking device of this embodiment.
First locking mechanism 13 can be configured to common car door lock, for the lock door body 10 when door body 10 is in closed condition.Such as, when cab door is closed, the dead bolt of the first locking mechanism 13 can spring in the lockhole be formed on doorframe 16 (or the support be fixed on doorframe 16) automatically, is locked on doorframe 16 by door body 10 thus.
Second locking mechanism 15 can be configured to the lock door body 10 when door body 10 is in open mode, to keep the open mode of a body 10.Such as, when door body 10 is opened to maximum open position, the dead bolt of the second locking mechanism 15 can spring in the lockhole that not shown car body member is formed automatically, thus door body 10 is locked in this car body member.In order to keep the open mode of a body 10 more reliably, the second locking mechanism 15 can with air spring acting in conjunction.The structure of this air spring and the mode of action are known in those skilled in the art, and at this, description is omitted.
First locking mechanism 13 and the second locking mechanism 15 can adopt the locking mechanism of any suitable type known in the art, and its concrete structure is also known in those skilled in the art, and at this, description is omitted.
In the illustrated embodiment in which, first control device 11 is arranged on door handle 17, and can be handled outward at driver's cabin by operating personnel.First control device 11 is connected to the first locking mechanism 13 by the first connector 12, and is connected to the second locking mechanism 15 by the second connector 14.Each in first connector 12 and the second connector 14 can be connecting rod or drag-line etc.
When door body 10 in off position under be locked in doorframe 16 by the first locking mechanism 13 time, if operating personnel turn the handle 17 at driver's cabin outer unlocking direction, the first control device 11 be then arranged on door handle 17 will activate the first locking mechanism 13 by means of the first connector 12, and its dead bolt is exited from the lockhole of doorframe 16.Thus, the first locking mechanism 13 is unlocked, thus operating personnel can open cab door.
On the other hand, when door body 10 is locked in car body member by the second locking mechanism 15 in the on-state, if operating personnel turn the handle 17 at driver's cabin outer unlocking direction, then first control device 11 will activate the second locking mechanism 15 by means of the second connector 14, and its dead bolt is exited from the lockhole of car body member.Thus, the second locking mechanism 15 is unlocked, thus operating personnel can close cab door.
First control device 11 can also be equipped with the latching member that can switch between open and closed positions.When this latching member is in enable possition, can by means of first control device 11, first locking mechanism 13 and the second locking mechanism 15 be unlocked as mentioned above, that is, first control device 11 be in " effectively " state.When this latching member is in the closed position, first control device 11 is in engineering noise state in other words by locked, now cannot carry out the unblock of the first locking mechanism 13 and the second locking mechanism 15 by means of first control device 11.Such latching member is known to those skilled in the art, and can be handled outward at driver's cabin by key.
Second control device 21 is arranged on the inner side of a body 10, thus can handle at cabin interior.Second control device 21 can be snapper, knob, handle etc.Different from first control device 11, second control device 21 is without the need to arranging latching member.Second control device 21 is connected to the second locking mechanism 15 by the 3rd connector 22.3rd connector 22 can be connecting rod or drag-line etc.When door body 10 is locked in car body member by the second locking mechanism 15 in the on-state, operating personnel can activate the second locking mechanism 15 by handling second control device 21 by means of the 3rd connector 22, and its dead bolt is exited from the lockhole of car body member.Thus, in driver's cabin, the second locking mechanism 15 can be unlocked, thus allow to close cab door.
Industrial usability
The utility model is applicable to need under specific circumstances to keep cab door to be in the machine of any type of open mode, such as loader, compacting machine, land leveller, crane etc.Under the open mode of cab door, door body 10 is locked in car body member by the second locking mechanism 15, to prevent the car door opened due to the vibration that produces between operational period or to close due to external force such as wind or accidental impact.When operating personnel wish cab door to close, both by handling the locking that first control device 11 removes the second locking mechanism 15 outward at driver's cabin, the locking of the second locking mechanism 15 can be removed again by handling second control device 21 in driver's cabin.Therefore, under the open mode of cab door, the locking of the second locking mechanism 15 can be removed easily, and then close cab door.
It should be pointed out that embodiment described above only should be regarded as exemplary, the utility model is not limited to this embodiment.By considering the content of this manual, those skilled in the art can make multiple change and modification when not departing from scope of the present utility model or spirit.True scope of the present utility model is by claims and equivalents.
