Abstract
Description
Technical Field
[0001] This utility model relates to a locking mechanism and a composite anti-theft security door for an armory equipped with the mechanism, belonging to the technical field of locks and anti-theft doors. Background Technology
[0002] Due to the limitations of their intended use, traditional security doors often employ low-grade mechanical lock cylinders, which are easily picked using technical means, posing significant security risks. Furthermore, traditional security doors are typically designed to be unlocked by a single person, failing to meet the security requirements of specific organizations. Summary of the Invention
[0003] The present invention aims to solve the various problems mentioned above, and thereby provides a locking mechanism and a composite anti-theft security door for an armory having the mechanism.
[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: A locking mechanism, characterized in that it includes a dual-key drive control assembly, a locking plate, and a rotary drive actuation assembly; wherein, The dual-key drive control assembly includes two lock cylinders and a lock head slide plate that is synchronously driven and controlled by the two lock cylinders; The turntable drive actuator includes a turntable, a transverse slide controlled by the turntable drive, and a side bolt plate, an upper bolt plate, and a lower bolt plate controlled by the transverse slide plate drive. The locking plate is rotatably mounted between the dual-key drive control assembly and the turntable drive execution assembly. It has a control arm that is linked to the lock head slide plate and a locking arm that is linked to the transverse slide plate.
[0005] Furthermore, the two lock cylinders of the dual-key drive control assembly jointly drive the lock head slide plate through the lock head dial shaft. The reciprocating sliding of the lock head slide plate drives the locking plate on one side to lock or unlock the turntable drive execution assembly.
[0006] Furthermore, the connection structure between the lock cylinder slide plate and the inside of the door is as follows: three guide shafts are arranged on the lock body mounting plate inside the door, and three elongated holes are correspondingly opened on the lock cylinder slide plate. When two keys turn the lock cylinder at the same time, the two lock cylinder pivot shafts rotate and jointly drive the lock cylinder slide plate to slide towards the opening side. At this time, the lock cylinder slide plate will slide a certain distance with the cooperation of the elongated holes and the guide shafts.
[0007] Furthermore, the locking plate is rotatably mounted on the lock body mounting plate inside the door body via a pivot, and its control arm is connected to the lock head slide plate via a pin. The locking arm has a lock groove, which is used to fit the lock shaft on the horizontal slide plate. When the lock head slide plate slides left and right, it will pull the control arm of the locking plate to swing, so that the lock groove of the locking arm on the other side contacts or separates from the lock shaft.
[0008] Furthermore, the turntable drives the transverse slide plate via a turntable lever, the side bolt plate is fixed to one side of the transverse slide plate, and the upper bolt plate and lower bolt plate are respectively installed at the upper and lower ends of the transverse slide plate via longitudinal slide plates. The two longitudinal slide plates are stacked and movably connected to the transverse slide plate.
[0009] Furthermore, the connection structure between the transverse sliding plate and the inner side of the door is as follows: three guide shafts are arranged on the lock mounting plate inside the door, and three elongated holes are correspondingly opened on the transverse sliding plate.
[0010] Furthermore, the connection structure between the transverse slide plate and the two longitudinal slide plates is as follows: the two longitudinal slide plates are respectively provided with two longitudinal long straight holes and one oblique long hole, and the oblique long hole is located between the two longitudinal long straight holes. The two longitudinal long straight holes are respectively adapted to the two guide grooves arranged above and below the lock body mounting plate. The oblique long hole in the middle is used to adapt to the oblique hole guide shaft on the transverse slide plate, and the oblique long holes of the two longitudinal slide plates are arranged in a non-sequential cross configuration.
[0011] A type of door that is special in that it is equipped with the aforementioned locking mechanism.
[0012] A composite anti-theft security door for an armory includes a door frame, an outer door leaf, and an inner door leaf, characterized in that the outer door leaf is equipped with the aforementioned locking mechanism.
[0013] This utility model discloses a lock mechanism that implements a double-person, double-lock linkage unlocking method. Traditional double-person, double-lock mechanisms involve installing an additional mechanical anti-theft lock on top of an existing mechanical anti-theft lock on the security door. Opening the door requires simultaneously pressing down the handles of both mechanical locks, making the process cumbersome. The advantage of this utility model's lock mechanism lies in its use of a rotary table to directly drive the sliding plate, achieving linkage of the upper, middle, and lower bolt points. Furthermore, compared to anti-theft locks, the sliding plate mechanism's components are less prone to deformation, resulting in lower maintenance costs and meeting the rapid response requirements of special units.

Detailed Implementation
[0015] The present invention will now be described in detail with reference to the accompanying drawings.
[0016] Example 1 A locking mechanism for dual-person, dual-lock management includes a dual-key drive control component, a locking plate 13, and a rotary drive execution component; wherein the dual-key drive control component is used to drive and control the locking plate 13, and the locking plate 13 is used to lock or unlock the rotary drive execution component.
[0017] The dual-key drive control assembly includes two Class C mechanical anti-theft lock cylinders 10, a lock cylinder dial 11, and a lock cylinder slide plate 12. The two Class C mechanical anti-theft lock cylinders 10 jointly drive the lock cylinder slide plate 12 through the lock cylinder dial 11. The reciprocating sliding of the lock cylinder slide plate 12 drives the locking plate 13 on one side to lock or unlock the turntable drive execution assembly.
[0018] Specifically, two Class C mechanical anti-theft lock cylinders 10 are mounted side-by-side on the door, with the lock cylinder holes located at the front end of the door. Two keys are held by two different people. The ends of the two lock cylinders are driven simultaneously by two lock cylinder pivot shafts 11, which drive the lock cylinder slide plate 12 to slide inside the door. The connection structure between the lock cylinder slide plate 12 and the inside of the door is as follows: three guide shafts are arranged on the lock body mounting plate inside the door, and three elongated holes are correspondingly opened on the lock cylinder slide plate 12. When both keys turn the lock cylinders simultaneously, the two lock cylinder pivot shafts 11 rotate, jointly driving the lock cylinder slide plate 12 to slide towards the opening side. At this time, the lock cylinder slide plate 12 will slide a certain distance with the cooperation of the elongated holes and the guide shafts. The locking plate 13 has a rotating end and two swing arms, one of which is a control arm linked to the lock cylinder slide plate 12, and the other swing arm is a locking arm associated with the turntable drive execution component. The rotating end of the locking plate 13 is rotatably mounted on the lock body mounting plate inside the door body via a rotating shaft. Its control arm is connected to the lock head slide plate 12 via a pin. When the lock head slide plate 12 slides, it will pull the control arm of the locking plate 13 to swing at a certain angle, thereby causing the locking plate 13 to rotate around the rotating end, and then causing the locking arm at the other end to swing to the unlock position.
[0019] The turntable drive assembly includes a turntable 20, a turntable lever 21, a transverse slide plate 22, a side bolt plate 23, an upper bolt plate 24, and a lower bolt plate 25. The turntable 20 drives the transverse slide plate 22 via the turntable lever 21. The side bolt plate 23 is fixed to one side of the transverse slide plate 22. The upper bolt plate 24 is mounted on the upper end of the transverse slide plate 22 via a first longitudinal slide plate 241, and the lower bolt plate 25 is mounted on the lower end of the transverse slide plate 22 via a second longitudinal slide plate 251. The two longitudinal slide plates are stacked and movably connected to the transverse slide plate 22. When the turntable 20 is rotated, the turntable lever 21 causes the transverse slide plate 22 to slide left and right, thereby controlling the side bolt plate 23, upper bolt plate 24, and lower bolt plate 25 to perform corresponding locking and unlocking actions.
[0020] Specifically, the turntable 20 is installed on the door body and has an operating end located on the outside of the door and a driving end located on the inside of the door. The driving end on the inside of the door is connected to a turntable lever 21, which is then hooked onto the horizontal sliding plate 22, thereby transmitting the torque of the turntable 20 to the horizontal sliding plate 22. The connection structure between the horizontal sliding plate 22 and the inside of the door body is as follows: three guide shafts are arranged on the lock body mounting plate inside the door body, and three elongated holes are correspondingly opened on the horizontal sliding plate 22. The connection structure between the horizontal sliding plate 22 and the two longitudinal sliding plates is as follows: the two longitudinal sliding plates each have two longitudinal elongated straight holes 22a and one 45-degree oblique elongated hole 22b, and the oblique elongated hole 22b... Located between two longitudinal elongated straight holes 22a, which are respectively adapted to the two guide grooves configured on the upper and lower parts of the lock body mounting plate, the middle oblique elongated hole 22b is used to adapt to the oblique hole guide shaft on the transverse slide plate 22, and the oblique elongated holes 22b of the two longitudinal slide plates are arranged in a non-sequential cross configuration. When the turntable 20 is turned, the turntable lever 21 will pull the transverse slide plate 22, causing the transverse slide plate 22 to slide a certain distance under the cooperation of the elongated hole and the guide shaft. At the same time, the side bolt plate 23 on one side of the transverse slide plate 22 moves accordingly, and the two longitudinal slide plates slidably connected to the transverse slide plate 22 move up and down simultaneously under the cooperation of the oblique hole guide shaft and the oblique elongated hole, so as to control the upper bolt plate 24 and the lower bolt plate 24 to complete the upper and lower bolt action, thereby realizing the opening and closing of the door leaf.
[0021] The transverse slide plate 22 is equipped with a locking shaft 221, and the locking arm of the locking plate 13 is provided with a locking groove 131 for locking the locking shaft 221. When the locking plate 13 rotates, the transverse slide plate 22 of the turntable drive actuator can be unlocked or locked.
[0022] The design principle and operation process of a locking mechanism in this embodiment are as follows: I. Startup Process Two mechanical keys are inserted into the Class C mechanical anti-theft lock cylinder 10 and simultaneously turned to open it. The two lock cylinder pivots 11 simultaneously turn the lock cylinder slide plate 12, pulling the lock cylinder slide plate 12 from the locked position to the open position. At the same time, the locking plate 13 linked with the lock cylinder slide plate 12 rotates, causing the locking plate 13 to rotate and unlock the horizontal slide plate 22 on one side. At this time, turning the turntable 20 will retract the bolts in all directions, and the door will open.
[0023] II. Locking Process When the horizontal slide plate 22 is in the unlocked state, the rotary dial 20 is turned to extend the bolts in each direction, and the horizontal slide plate 22 slides from the unlocked position to the locked position. At this time, two mechanical keys are inserted into the Class C mechanical anti-theft lock cylinder 10 and simultaneously reversed. The two lock head pivots 11 simultaneously move the lock head slide plate 12, pulling the lock head slide plate 12 from the open position to the locked position. At the same time, the lock head slide plate 12 controls the locking plate 13 to rotate and fall back, locking the position of the horizontal slide plate 22. At this time, the rotary dial 20 cannot be turned from the outside, and the door closes.
[0024] Example 2 This embodiment relates to a security door employing the locking mechanism described in Embodiment 1.
[0025] Example 3 This embodiment relates to a composite anti-theft security door for an armory, employing a composite structure of one frame and two doors. It includes a door frame 40 and an outer door leaf 41 and an inner door leaf 42, which are movably mounted on the door frame 40 via high-strength hinges. The outer door leaf 41 uses a thick sheet metal as the door panel and employs the locking mechanism 43 described in Embodiment 1 instead of a traditional mechanical lock, ensuring safety, reliability, and extremely strong anti-vandalism capabilities. The inner door leaf 42 is equipped with a new type of detachable mechanical lock. It also features two Class C mechanical anti-theft lock cylinders, allowing for dual-person, dual-lock management; the cover plate handle is detachable. Compared to ordinary locks where the outer handle and front cover plate are combined and a single lock is used, the front cover plate and outer handle are detachable, enabling dual-lock opening and allowing for hierarchical management in special units. This embodiment describes a specially designed anti-theft door locking mechanism developed for armories. It implements a two-person, two-lock linkage management system, with the key held by two people, one of whom must be the department head. Both people must be present at the same time to open the door, which meets the security requirements of special units.
