Description
Technical field
The utility model belongs to door lock, and in particular to a kind of railway stone tiny fragments of stone, coal, etc. hopper wagon control cabinl pulpit door lock.
Background technology
The principal mode product of current existing railway lorry stone tiny fragments of stone, coal, etc. hopper wagon is 70t grades of stone tiny fragments of stone, coal, etc. hopper wagons.One is set on its car body
Control cabinl pulpit.Control cabinl pulpit door lock (such as Fig. 1) uses billiards lock structure, is closed using the secondary latch of latch plus key lock.Latch is by door lock
Control is passed through Revolving door lock operating handle latch by hand；Key lock uses the operable key lock of key by door keys control；
Key is common monolithic key.
Stone tiny fragments of stone, coal, etc. hopper wagon is in long-term outdoor, unobstructed job state, determine the use environment of control cabinl pulpit door lock compared with
To be severe.And the key lock pin of the door lock is arranged as exposed, outside is without any safeguard procedures, in the presence of artificial external force,
Lock core internal structure destructible；Exposed lock core is caused its serious corrosion by dust storm, the erosion drenched with rain；Directly affect door lock
Performance.
Key is common monolithic pattern, and intensity is weaker.Lock core can cause key lock to rotate bad after damage and corrosion；
Along with the vibrations in the error and vehicle operation in assembling process, the fit dimension for causing door-plate and doorframe is difficult to protect
Card.When opening and closing key lock using key, relatively elaborate, the moment of torsion that key is born is excessive, and intensity is not enough, Zhu Duoshi
Tiny fragments of stone, coal, etc. hopper wagon occurs in that the phenomenon that key fractures.Control cabinl pulpit door lock manufacturer also disunity, same user's different batches
The key that stone tiny fragments of stone, coal, etc. hopper wagon is attached troops to a unit also is not quite similar, the problem of user often obscures key.
It is 11mm to lock latch dead bolt overhang, and the dead bolt overhang of key lock is 16mm.Latch dead bolt is than key lock dead bolt
Short 5mm, if only using latch in vehicle operation, easily cause causes the automatic of control cabinl pulpit car door to beat because vehicle dynamically jolts
Open, there is potential safety hazard, influence traffic safety.
Door lock once goes wrong, can directly result in user can not normally enter control cabinl pulpit carry out unload tiny fragments of stone, coal, etc. operation.To avoid
Because door lock can not be opened, the decline of vehicle performance is caused.Need a kind of new stone tiny fragments of stone, coal, etc. hopper wagon control cabinl pulpit door lock knot of design badly
Structure, makes it both adapt to original car door door lock installation structure, and operating personnel can be allowed smoothly to complete vehicle into control cabinl pulpit again and unload the tiny fragments of stone, coal, etc.
Operation.
The content of the invention
The utility model is in order to solve the problems with that existing stone tiny fragments of stone, coal, etc. hopper wagon is present：
A. door keys lock is because of exposed, unshielded measure, and caused lock core is fragile, corrosion is serious.
B. after vibrations and lock core corrosion of the lock core in vehicle operation, the phenomenon that caused key fractures, Yi Jiyin
Key disunity, the easy confounding issues of user caused.
C. latch is different from key lock dead bolt overhang, and dead bolt and locking board amount of lap are small, easily causes because vehicle is dynamically run
Winnowing with a dustpan causes automatically opening up for control cabinl pulpit car door, there is potential safety hazard.
D. locking board is not enough with doorframe riveting intensity, and caused locking board easily loosens, come off, and influences control cabinl pulpit car door lock
Close reliability and sealing property.
E. because door lock can not be normally-open, user is caused smoothly to carry out unloading tiny fragments of stone, coal, etc. operation into control cabinl pulpit.
The utility model adopts the following technical scheme that realization：
