Description
Technical field
The utility model relates to lock technology field, is specifically a kind of door bolt lock.
Background technology
The door bolt lock of prior art comprises body, slide bar and one handle, and described slide bar is slidably fitted in body, and described handle is fixedly connected with slide bar.When use, direct control handle can be realized the insertion of slide bar and extract, to complete locking or the movement of door.The door bolt of said structure is locked in actual use procedure and has the following disadvantages: for the family or public place that has child for some, because this door bolt lock can direct control, therefore being easy to be treated as toy plays, thereby not only can affect the application life of door bolt lock, and can move because slide bar skids off back door, be therefore easy to squeeze and hinder child.
Utility model content
The technical problems to be solved in the utility model is that a kind of door bolt lock that can limit slide bar position is provided.
The technical solution of the utility model is, a kind of door bolt lock is provided, and comprises body, slide bar and one handle, and described slide bar is slidably fitted in body; Described door bolt lock also comprises that one for limiting the lock of slide bar position, and described lock comprises lock core, travelling carriage and be fixed on the lock housing on body, and described lock core is slidably fitted in lock housing; Described lock core is also slidably matched with travelling carriage, and the rotating shaft of described lock core is provided with a breach, and described travelling carriage is provided with a projection offseting with rotating shaft; Described slide bar is made up of the first slide bar and the second slide bar; The two ends of described the first slide bar are connected with one end of handle, travelling carriage respectively; One end of described the second slide bar is free end, and the other end of described the second slide bar is connected with the other end of travelling carriage.
Described lock core is provided with symmetrically arranged two slide blocks and symmetrically arranged two slide bars; The center of described two slide blocks connects mutually vertical with the line of centres of two slide bars; In described lock housing, be provided with two grooves that slide for two slide blocks respectively; Described travelling carriage is provided with the waist-shaped hole of two oblique lower settings of sliding for two slide bars respectively.
On the second described slide bar, be also provided with a blind hole, described blind hole is connected with spring and a steel ball; On described body, be also provided with two holes that are partially submerged into for steel ball; Distance between described two holes equates with the outreach of the second slide bar.
Adopt after above structure, the utility model compared with prior art, has the following advantages:
When the utility model door bolt lock uses, direct control handle inserts slide bar in spacing hole or stopper slot, then turn key lock, now, in the time of operating grip, lock core inwardly slides, but because projection and rotating shaft offset, making cannot operating grip, has realized locking.And in the time again rotating key, projection is corresponding with gap position, now projection is not stopped, can operating grip.The utility model can limit in the time that slide bar inserts spacing hole or stopper slot, prevent operating grip, therefore for the family or public place that has child for some, being difficult for being treated as toy plays, thereby not only ensure the application life of door bolt lock, and owing to locking, so door cannot freely rotate, hinder child thereby be difficult for squeezing.
