Abstract
The utility model relates to a main lock body structure with a parallel moving lock cylinder. A keyhole is arranged on a lock head main body. The lock head main body and the lock body assembled are two independent parts. An external main lock block is provided with a long leg while an internal main lock block is free from the long leg. The external and internal main lock blocks are same in other shapes. Based on a bolt fixing frame as a reference face, difference number in the vertical and parallel states of the external and internal main lock blocks is just length of a superwide main bolt extending. Conventional mechanical theft-proof core-inserting structure is improved to the structure with the parallel moving lock cylinder, so that the main spring bolt (bolt) of the mechanical theft-proof lock widely applied to steel protective doors has multiple heads. The complex main lock body structure is simplified, and all functions of the conventional mechanical theft-proof lock are reserved, and a great part of production raw materials and manufacturing steps are reduced, and in particular the labor cost is lowered.
Description
Technical field:
The utility model relates to the master lock body structure that lock core is rotary tapered end, especially a kind of master lock body structure of lock core parallel movable.
Background technology:
Known, traditional lock core is revolving tapered end, is all supporting with lock pin form structure and master lock body, and its tapered end and master lock body are two independent separate components.Using mechanical anti-theft lock on safety steel door widely as example, tapered end be with special-purpose equipment through tens procedure manufacturings, technological requirement that also will be higher; And the master lock body is complicated by dead bolt part and the internal construction of multi-end bolt (bolt), and part all forms at the master lock body more than tens.Above-mentioned this numerous part and manufacturing process are in fact just only for realizing a function: key rotation lock core, lock core are stirred dead bolt and are entered the doorframe opposite house and lock.Manufacturing process and various raw-material consumption that so simple two actions, mechanical anti-theft lock but will be experienced more than 50 roads just can be completed, and particularly in today that cost of labor improves year by year, this can't but be a kind of waste.
The utility model content:
Sum up the above, the utility model provides a kind of master lock body structure of lock core parallel movable.
The technical scheme that its technical problem that solves the utility model adopts is: the mechanical anti-theft lock on the safety steel door as example, is at first to have carried out improvement and the design of simplified style from tapered end to the master lock body, has removed the lock housing part of master lock body.Tapered end main body and lock body are two independent independent sectors when assembling is completed, outer master lock piece has long pin and the not long pin of interior secondary lock piece, their other shapes are all identical, take the locking bolt fixed mount as datum, the difference number that their erectility and parastate produce is just the length that super wide master latch stretches out.
Between tapered end main body and parallel movable lock core, back-moving spring is installed, in the locking bolt fixed mount, spring leaf is installed, keyhole is opened on the tapered end main body, and key can not rotate after inserting, and lock core can only parallel direction move in the tapered end main body.
The use function of the utility model master lock body is to realize like this; Supporting parallel movable lock core in the tapered end main body, the location between them is to be realized by three layers of pellet that run through the parallel movable lock core.
Direction outside the shop front; When key does not insert keyhole, the pellet dislocation in marble hole, tapered end main body and portable lock core are in the lock state.When outer master lock piece was in parastate, its front end withstands the locking bolt fixed mount stretched out outside the door leaf edge line super wide master latch, and lock body is in the lock state.Just blocked parallel movable lock core pressure can not be moved back if press down the long pin of the outer master lock piece of handle, outer master lock piece just can the up time direction not move down, and door just can not be unlocked.When key inserted, pellet will automatically reset, and lock-out state is removed.If pressing down the long pin of the super wide master latch of handle just can move back parallel movable lock core pressure, it is passed through smoothly, the end face that this moment, outer master lock piece withstood the locking bolt fixed mount will be transformed into the side, the alternate position spike to the locking bolt fixed mount due to end face and side, add the effect of locking bolt fixed mount inner spring sheet, its super wide master latch is returned in the door leaf edge line voluntarily, and door just has been unlocked.If do not extract key, the long pin of the outer master lock piece of upper handle just can pass through the parallel movable lock core smoothly, and its side of withstanding the locking bolt fixed mount just can be transformed into end face again, and super wide master latch is stretched out outside the door leaf edge line, and door has been closed again.
Direction in door is not controlled because the not long pin of interior secondary lock piece can not be subjected to the resistance of parallel movable lock core.In when carrying on handle, the end face of secondary lock piece just can eject the locking bolt fixed mount together with super wide master latch, and door has just been closed.And the end face that handle withstands the locking bolt fixed mount when pressing down will be transformed into the side with the effect of spring leaf, and door just has been unlocked.The handle that is arranged on an inside/outside carry on completing or can self-resetting during pressing action to parastate.
The beneficial effects of the utility model are; Master lock tongue (bolt) multi-head with conventional ferrule formula mechanical anti-theft lock, the complicated simple question that is returned to of master lock body structure is oversimplified, with tapered end main body simple in structure and parallel movable lock core, supporting with outer master lock piece/interior secondary lock piece and lock body, realized the repertoire of traditional mechanical anti-theft lock, and can reduce a large amount of production raw material, manufacturing process and recruitment cost.
