Abstract
The utility model relates to a component for a cipher lock, particularly the improvement of the lock seat of the cipher lock. The utility model is characterized in that the flat bottom of the lock seat is fixed to the outer side of a cabinet wall, a cylinder body used for assembling an encoding piece is separated from the lock seat and is fixed on the inner wall of the cabinet wall, and the inner part of the cabinet wall only is provided with a part of driving shaft rod. The utility model has the advantages of easy processing and convenient assembly, and the structure enhances the safety performance of the cipher lock.
Description
The utility model relates to a kind of member of coded lock, especially the improvement of coded lock lock.
Now use the safety cabinet coded lock, its lock all has a cylindrical shape disjunctor, is used to assemble coded slice, spring, packing ring, and make turning cylinder pass through its centre bore, outside this lock installation insurance cabinet, cylindrical shape disjunctor and spring are loaded in the safety cabinet wall, and coded slice and packing ring are loaded in the safety cabinet.The shortcoming of this structure is then to destroy locking mechanism easily when piercing the lock center with drill bit, opens safety cabinet, or violence pulls out tapered end, can open safety cabinet too.Its fail-safe is poor, and this structure processing is more complicated.
The purpose of this utility model is to provide a kind of processing more or less freely, easy to assembly, and security personnel give birth to strong lock structure.
The purpose of this utility model is achieved in that the safety lock holder structure comprises the cabinet wall, is contained in the outer lock of cabinet wall, the power transmission shaft that tapered end on lock and tapered end are connected as a single entity; Its characteristics are that lock is flat, are fixed in outside the cabinet wall, and the cylinder that is used to assemble coded slice, spring and packing ring etc. separates with lock, is fixed on the cabinet wall inwall, and the part transmission shaft lever is only arranged in the cabinet wall.
Advantage of the present utility model is: adopted cylinder and lock isolating construction, the difficulty of processing of avoiding the little seat of axle to cause greatly is big, the waste of material; Cylinder is contained on the cabinet wall inwall, even destroy formal structures such as power transmission shaft or lock, also can't make locking device malfunctioning, thereby improved security performance, power transmission shaft is only arranged in the cabinet wall, the diameter of axle is less, space in the cabinet wall is also less, has made things convenient for assembling, has also improved security performance.
Below in conjunction with embodiment shown in the drawings.The utility model is further described.
Fig. 1 structure half sectional view of the present utility model
1, tapered end 2, power transmission shaft 3, cabinet wall 4, lock 5, cylinder
6, spring 7, packing ring 8, coded slice 9, screw 10, spring shim
The lock of former usefulness all has a columnar disjunctor, present embodiment then is divided into disome, lock 4 usefulness screws 9 are installed in the outside of safety cabinet cabinet wall 3, one end of cylinder 5 is made the shaft shoulder of certain diameter, with screw 9, be fixed on by the shaft shoulder on the inwall of cabinet wall 3, the other end then is used to assemble parts such as spring 6, packing ring 7 and coded slice 8.Tapered end 1 is installed on the lock 4, and power transmission shaft 2 is controlled the rotation of coded slice 8 by centre bore, the hole of cabinet wall 3 and the hole in the cylinder 5 of lock 4.
In the present embodiment, promptly use bit drills to go into tapered end 1, pass lock 4, destroyed power transmission shaft 2, power transmission shaft 2 parts are then stayed in the cylinder 5, and cylinder 5 is fixed on the inwall of cabinet wall 3, can not come off or loosening.As unreserved seating, locking device still in action, safe door is not opened.As by force tapered end 1 and 2 whole of power transmission shafts being extracted, cylinder 5 is fixed on the inwall, because the coded slice 8 more than 1 or 1 is still blocked in the effect of spring shim 10, does not have power transmission shaft 2, can't contraposition, also can't open safety cabinet.As pierce tapered end 1 with starting drill, because the hole on the safety cabinet cabinet wall 3 is less, can't drill through, its security performance must be given raising.
Claims (2)
1, the safety lock holder structure comprises the cabinet wall, be contained in the outer lock of cabinet wall, tapered end on lock, the power transmission shaft that is connected as a single entity with tapered end, it is characterized in that: lock is flat, is fixed on outside the cabinet wall, and the cylinder that is used to assemble coded slice, spring and packing ring etc. separates with lock, be fixed on the cabinet wall inwall, the part transmission shaft lever is only arranged in the cabinet wall.
