Abstract
The utility model provides a combined mechanism of a mechanical coded lock, which comprises a shell, and a mechanical lock, a coded lock, and an inserting plate are arranged in the shell, wherein a plurality of pin heads are arranged at the edge of the inserting plate, and pass through the shell. The shell is also provided with a coupled sheet, one end of which is firmly fixed with a bolt of the mechanical lock, and the other end is provided with an elbow. The inserting plate is also provided with a guard sheet which is arranged at the sidepiece of the coupled sheet. Generally, the combined mechanism of a mechanical coded lock is arranged in a cabinet door of a safe. Because the utility model adopts the method of using the mechanical lock and the coded lock to doubly restrict the movement of the coupled sheet, the antitheft performance is improved significantly.
Description
The utility model relate to a kind of be used for antitheft, the mechanical code lock composite structure that uses on strongbox or the safety cabinet particularly.
At present, mechanical lock and coded lock are widely used on strongbox or the safety cabinet.People are in order to improve the theftproof performance of strongbox, generally are to adopt on the cabinet door of strongbox or safety cabinet mechanical lock and coded lock are installed simultaneously.Like this, the theftproof performance of strongbox is doubled.But because these two locks are fully separate, so the burglar can adopt the means of defeating in detail, a little longer purpose that also can reach unlatching of time.
The purpose of this utility model is to consider the problems referred to above, and a kind of new mechanical formula coded lock composite structure is provided, and it cooperatively interacts by mechanical lock and coded lock, and its theftproof performance is significantly increased.
The purpose of this utility model realizes by following technical proposal: this mechanical code lock composite structure comprises a housing, be provided with a mechanical lock, a coded lock and a plate in the housing, the edge of plate is provided with several pin heads, the pin head passes housing, also be provided with a double-action plate in the housing, double-action plate is between mechanical lock and coded lock, one end of double-action plate and the dead bolt of mechanical lock are connected, the other end is provided with an elbow that can insert in the coded lock locking plate split shed groove, a catch also is set on the plate, and catch is positioned at the double-action plate sidepiece.The composite structure of this mechanical code lock is generally positioned in the cabinet door of strongbox.It is to block moving of plate by double-action plate, locks the cabinet door.Because the dead bolt and the double-action plate of mechanical lock are connected, have only key to insert in the mechanical lock core and key with mechanical lock, double-action plate could move.Simultaneously, the mobile restriction that also is subjected to coded lock of double-action plate.When coded lock was not squared with, the locking plate recess groove in the coded lock was not to be in same position simultaneously, and the elbow on the double-action plate can only be on the periphery of locking plate, and double-action plate can not move down.
Compared with prior art, the utility model is owing to adopt moving of mechanical lock and the dual restriction double-action plate of coded lock, reach the purpose of locking insert, so its theftproof performance is better than the structure that is formed by two separate mechanical locks and coded lock simple superposition far away.
Below in conjunction with embodiment and accompanying drawing thereof structure of the present utility model is described further.
Accompanying drawing is the schematic diagram of the mechanical code lock composite construction that provides of the utility model.
Among the figure, 1, housing; 10, lead; 2, plate; 20, pin head; 21, catch; 3, coded lock; 30, locking plate; 300, open slot; 4, mechanical lock; 40, dead bolt; 5, double-action plate; 50, elbow; 51, spring; 52, bar hole; 6, handle axle; 7, connecting rod.
As shown in the figure, this mechanical code lock composite construction comprises housing 1, plate 2, mechanical lock 4, coded lock 3 and double-action plate 5.Mechanical lock 4 and coded lock 3 are fixed on the housing 1.The dead bolt 40 and the double-action plate 5 of mechanical lock 4 are connected.In the present embodiment, double-action plate 5 is provided with bar hole 52, and the position corresponding to bar hole 52 on the housing 1 is provided with lead 10.During use, lead 10 inserts in the bar hole 52, and double-action plate 5 can only longitudinally be moved up and down.Be provided with spring 51 between double-action plate 5 and the housing 1.The effect of spring 51 has two: the one, shield, and the thief destroys even the mechanical lock in this mechanism is stolen, because this spring 51 is arranged, double-action plate 5 can not fall down yet, entire mechanism still can not be opened; The 2nd, play reset response, when using at ordinary times, lock is locked rear spring 51 double-action plate 5 is resetted, easy to operate.The top of double-action plate 5 is elbow 50, and its size is slightly smaller than the size of coded lock locking plate 30 upper shed grooves 300, and elbow 50 can be inserted in the open slot 300.In the present embodiment, plate 2 also is socketed on the housing 1 by lead 10, makes that plate 2 can only be along laterally moving.Pin 20 passes housing 1 on the plate 2.Catch 21 is positioned at the sidepiece of double-action plate 5, and is connected as a single entity with plate 2.Catch 21 limits moving of plate 2, has only when the elbow on the double-action plate 5 50 enters open slot 300 on the locking plate 30, just eliminates this restriction, and plate 2 can move left and right.This residing state when this mechanism opens just.
In this mechanism, the handle in housing 1 outside connects with the handle axle 6 of passing housing 1.Connecting rod 7 is being fixed in the inner of handle axle 6, and connecting rod 7 is hinged with plate 2.When plate 2 was not restricted, pulling handle just can make plate 2 laterally move, control pin 20 stretches.
The specific operation process of this mechanical code lock is as follows: the dialing dish of rotational password lock 3 at first, make that each open slot 300 is in elbow 50 residing positions simultaneously in the coded lock locking plate 30, and so just removed the restriction that coded lock moves double-action plate 5; Insert the key and the rotation of mechanical lock 4 then, drive dead bolt 40 and shrink, and double-action plate 5 is moved down; At last, as long as pull housing 1 handle outward, just can open entire mechanism by handle axle 6 and connecting rod 7.
