Abstract
The utility model discloses a compartment door lock in the technical field of lock, which has a case body, a plug, a bolt, a handle, as well as a locking plate, wherein: the end part of the plug is fixedly equipped with an eccentric cam, the eccentric cam is clamped in a slot of bolt end part, the case body is fixedly equipped with a pressure plate, a slideway that the bolt can pass is arranged between the pressure plate and the case body, and two sides of the pressure plate is equipped with a baffle that can obstruct the locking plate from rotation; a cylinder of the locking plate and the body of the locking plate is a integral structure, a pin shaft crosses the locking plate to be fixed on the case body, and a bolt crosses a gasket to axially fix the locking plate. Comparing with the prior art, the utility model has the characteristics of simple structure, stable lock properties and high strength, which is not easy to be destroyed.
Description
Technical field
The utility model belongs to lock technology field, is specifically related to a kind of hatch door lock.
Background technology
At the hatch door of various metal material, the locking of the hatch door of particularly various palace cars, special purpose vehicle, bodywork surface is to adopt the hatch door lockset.The hatch door lock that uses on the market mainly depends on import.This hatch door lockset has housing, lock core, dead bolt, handgrip and locking plate.Lock core is fixed on the housing, and the lock core end is provided with dead bolt, and dead bolt can be locked locking plate.Be provided with spring between dead bolt and housing, spring is in the state of straining at all the time, and the dead bolt structure that this spring stretches makes lockset fragile in the big adverse circumstances of desert or dust storm.Handgrip is connected with locking plate, and the tapered end of locking plate is flexible tapered end, and this flexible tapered end strength deficiency is fragile, causes the hatch door lock to lose efficacy.
Summary of the invention
For solving the problems of the technologies described above, it is a kind of simple in structure that the purpose of this utility model is to provide, lockset stable performance, intensity height, non-damageable hatch door lock.
For achieving the above object, the technical solution of the utility model is improved on the basis of existing hatch door lock, end at lock core is installed with eccentric cam, eccentric cam is installed in the draw-in groove of dead bolt end, be installed with pressing plate on the housing, be provided with the slideway that dead bolt can pass through between pressing plate and housing, the pressing plate both sides are provided with the baffle plate that stops the locking plate rotation; The tapered end of described locking plate and locking plate body are monolithic construction, and bearing pin passes locking plate and is fixed on the housing, bolt by pad with the locking plate axial restraint.
Adopt the beneficial effect of technique scheme: the end that this hatch door is locked in lock core is installed with eccentric cam, eccentric cam is installed in the draw-in groove of dead bolt end, dead bolt is installed in the dead bolt slideway between pressing plate and the housing, lock core drives the eccentric cam rotation under the unlatching of key, it is flexible in the dead bolt slideway that eccentric cam rotation drives dead bolt, make dead bolt locking locking plate, thereby realize the unlatching or the locking of hatch door lock.Above-mentioned locking device structure is simple, and intensity is high to be connected reliably, and stable drive is difficult for jam.The tapered end of locking plate and locking plate body are monolithic construction, the intensity height of locking plate, and tapered end is not fragile.
Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail.
