Description
Technical Field
The utility model relates to a side column locking anti-theft marble lock cylinder, in particular to a composite marble side column locking anti-theft marble lock cylinder.
The background technology is as follows: the utility model provides a tool to guard against theft that tool to guard against theft is indispensable in people's daily life, the lock generally includes lock shell and rotationally sets up the lock core in the lock shell, is provided with the key slot that supplies key male in the lock core axial, lock shell and lock core relevant position are provided with a plurality of pellet shot from a slingshot lockholes, pellet shot from a slingshot lockhole is arranged in a row along lock shell and lock core axial, the cylindricality pellet shot from a slingshot group that reset spring, flat head pellet shot from a slingshot and solid pellet shot from a slingshot constitute has been set gradually along lock shell to lock core direction in the pellet shot from a slingshot lockhole, and the bullet proof tapered end of this kind of structure is because the key that corresponds only single row tooth flower, is dialled by the tool to be opened easily, and the theftproof performance is poor.
In order to improve the anti-theft performance of the lock and increase the difficulty of technical unlocking, various anti-theft cylinder locks, such as cylinder locks with side column locking mechanisms, are designed. The lock core body is provided with a side lock ball hole row which is formed by a plurality of ball holes which are arranged along the axial direction in a straight line and are perpendicular to the axis, the side lock balls are arranged in the side lock ball holes, the side lock balls are in sliding fit with the side lock ball holes, the whole side lock ball is a columnar component, and an annular unlocking groove is formed in the cylindrical surface of the side lock ball. The side column locking mechanism comprises a slot which is arranged on the lock cylinder body in parallel with the axis and is vertical to and communicated with the side lock ball hole, a locking side groove which is arranged on the inner wall of the lock cylinder shell and corresponds to the slot, and a sheet locking side column which can slide in a channel formed by the slot and the locking side groove, wherein the thickness of the inner side of the locking side column is matched with the width gap of the ball unlocking groove. When the cylinder lock is locked, the inner side and the outer side of the locking side column are respectively positioned in the locking side grooves of the lock cylinder body and the lock cylinder shell, and as the unlocking grooves on all the side locking cylinders on the lock cylinder body are not positioned on the same straight line, the cylindrical surface of at least one side locking cylinder is propped against the inner side of the locking side column to prevent the locking side column from retracting into the lock cylinder body, and the outer side of the locking side column is clamped in the locking side groove of the lock cylinder shell, so that the lock cylinder body and the lock cylinder shell can not rotate relatively; when unlocking, the tooth groove on the matched key interacts with the end part of the side lock marble to force the position of each marble to change until the unlocking groove on the side lock marble is in a straight line, at the moment, the inner side of the locking side column slides into the unlocking groove on the marble, the outer side of the locking side column is retracted into the lock cylinder body from the lock cylinder shell, and the lock cylinder body can rotate relative to the lock body to complete unlocking. Because the side column locking mechanism is additionally arranged in the cylinder lock, the lock cylinders of the side lock are difficult to simultaneously position by an unlocking tool of a non-matched key, unlocking grooves on the side lock cylinders are all overlapped, the inner side of the locking side column cannot slide into the unlocking grooves on the side lock cylinders, and the locking side column cannot retract from the lock cylinder shell, so that the lock cannot be opened, and the safety and the anti-theft performance of the cylinder lock are greatly improved. However, under the condition that the safety and the anti-theft performance of the anti-theft lock with the structure are improved, the mechanical strength of the side lock marble is greatly reduced due to the annular unlocking groove arranged on the cylindrical surface of the side lock marble, so that the performance of the existing side column locking anti-theft marble lock core for resisting violent unlocking is also greatly reduced.
The utility model comprises the following steps: the utility model aims to overcome the defects of the prior art and provide the side column locking anti-theft marble lock cylinder with good anti-theft performance and high mechanical strength.
In order to solve the technical problems, the utility model adopts the following technical scheme: a composite marble side column locking anti-theft marble lock core comprises a lock core shell, a lock core body, a plurality of side lock marbles and a side column locking mechanism; the lock core body is provided with a marble hole row which comprises a plurality of side lock marble holes and is arranged along an axial straight line, the side lock marble holes are perpendicular to the axis, and side lock marble is arranged in the marble holes in a sliding fit manner; the side column locking mechanism comprises a slot groove arranged on the lock cylinder body, a locking side groove and a sheet locking side column, wherein the locking side groove and the sheet locking side column are arranged on the inner wall of the lock cylinder shell, the slot groove is perpendicular to the marble hole and communicated with the marble hole, and the sheet locking side column can radially slide in a channel formed by the slot groove and the locking side groove, and the side column locking mechanism is characterized in that: at least one or more ball lock holes are also arranged in the ball hole row, and a cylindrical ball group is arranged in the ball lock hole.
The utility model is further provided with: the side lock pin tumbler hole row is characterized in that one end or two ends of the side lock pin tumbler hole row are provided with pin tumbler lock holes, and cylindrical pin tumbler groups are arranged in the pin tumbler lock holes.
