Description

Technical Field

[0001] This utility model relates to the technical field of linkage latch mechanism, and in particular to a linkage latch mechanism for gun cabinet. Background Technology

[0002] As a controlled weapon, firearms have great destructive power. Due to their special function, the safekeeping of firearms has always been a very strict and important matter. Firearms are generally stored in gun cabinets, which are usually equipped with electronic or mechanical locks that can be opened by password, fingerprint or key to ensure the security of firearms storage.

[0003] A search revealed a Chinese patent publication number CN217950041U, which discloses a linkage latch mechanism, including a door panel, a mechanical anti-theft lock, a first nut, a connecting mechanism, a rotating mechanism, and a linkage mechanism. The mechanical anti-theft lock is connected to the middle of the right side of the door panel, and the first nut is rotatably connected to the left side of the mechanical anti-theft lock. The first nut can fix the mechanical anti-theft lock. A connecting mechanism is provided on the left wall of the door panel, and a linkage mechanism is provided in each of the connecting mechanisms. A rotating mechanism is provided on the left end of the mechanical anti-theft lock.

[0004] This patented device incorporates a mechanical anti-theft lock, a connecting mechanism, a rotating mechanism, and a linkage mechanism. When the lock is fitted onto the corresponding parallel pin rod, the gear rotation drives the vertical slide plate to slide up and down. The vertical slide plate then drives the latch to move up and down and insert into the pin nose, thus achieving linkage of the latch mechanism in this gun cabinet. The operation is simple, and it employs multiple protections, making it safe, reliable, and with smooth transmission that is not prone to jamming. However, when the lock is subjected to physical attack by forceful unlocking, it cannot send out an alarm in time, increasing the risk of theft. Utility Model Content

[0028] Example 1

[0029] A linkage locking mechanism for a gun cabinet, such as Figures 1 to 4 As shown, the device includes a door panel 1, a closed cover 2 connected to one side of the door panel 1 by bolts, a mechanical anti-theft lock 3 rotatably connected to one side of the door panel 1, a gear 5 rotatably connected to the inner wall of the door panel 1, and the mechanical anti-theft lock 3 connected to the shaft of the gear 5. The closed cover 2 has latch grooves 10 on all four sides. Vertical latches 6 are slidably fitted on the inner walls of the latch grooves 10 at the upper and lower ends of the closed cover 2. One end of the vertical latch 6 is connected to a rack 7. The two racks 7 are arranged opposite each other and mesh with the gear 5. Two actuating pins are fixed opposite each other on the outer wall of the gear 5. Horizontal latches 8 are slidably fitted on the inner walls of the latch grooves 10 on both sides of the closed cover 2. One end of the horizontal latch 8 is connected to a sliding ring 9. The actuating pins are slidably fitted on the inner walls of the sliding ring 9.

[0030] The side wall of the latch slide groove 10 is provided with an annular piezoelectric ceramic sensor 11 installed on the inner wall of the closed cover 2. A conductive post 12 is slidably fitted on the side wall of the latch slide groove 10. The two ends of the conductive post 12 are respectively in contact with the annular piezoelectric ceramic sensor 11 and the horizontal latch 8. A sliding cavity 13 is provided above the latch slide groove 10. A sliding plate 17 is vertically slidably fitted on the inner wall of the sliding cavity 13. A plug rod 16 is connected to the bottom end of the sliding plate 17.

[0031] The horizontal latch 8 has a through hole 14 on its side wall. The insertion rod 16 is limited to the through hole 14. An electromagnet 18 is fixed to the inner wall of the bottom end of the sliding cavity 13. A magnet 19 is fixed to the outer edge of the top of the sliding plate 17. The electromagnet 18 and the magnet 19 have the same magnetic poles. The side wall of the sliding cavity 13 is provided with two horizontally sliding limit blocks 20. The two limit blocks 20 are arranged opposite each other. The outer walls of the upper and lower ends of the two limit blocks 20 are both set as inclined surfaces inclined towards the axis of the limit blocks 20. The upper and lower outer walls of the sliding plate 17 are both set as inclined surfaces inclined towards the axis of the sliding plate 17. The inclined surfaces at both ends of the sliding plate 17 slide in cooperation with the inclined surfaces of the limit blocks 20. A spring 15 is connected to one end of the limit block 20. The other end of the spring 15 is connected to the sealing cover 2. An observation window 4 is provided on the side wall of the door panel 1. The observation window 4 is connected to a latch slide groove 10. An explosion-proof glass is installed inside the observation window 4. A marking line is provided on the outer wall of the horizontal latch 8 located on one side of the observation window 4.

[0032] In use, the inner side wall of the gun cabinet has insertion holes for the vertical latch 6 and the horizontal latch 8. The user inserts the key into the mechanical anti-theft lock 3, turns the mechanical anti-theft lock 3 to drive the gear 5 to rotate, and drives the rack 7 to move, so that the vertical latch 6 is inserted into the insertion holes at the top and bottom of the gun cabinet. At the same time, the actuating column drives the sliding ring 9 to move, so that the horizontal latch 8 extends outward and is inserted into the insertion hole on the side wall of the gun cabinet. During the rotation of the mechanical anti-theft lock 3, the user can observe through the observation window 4 whether the marking line has moved into the observation window 4 to determine the extension length of the horizontal latch 8. When external force damages the cabinet, the vertical latch 6... Either the vertical latch 6 or the horizontal latch 8 will be subjected to force, pushing the transmission column 12 to move and compress the ring piezoelectric ceramic sensor 11. When the ring piezoelectric ceramic sensor 11 detects pressure, the electromagnet 18 is energized. The repulsive force between the electromagnet 18 and the magnet 19 pushes the sliding plate 17 downward, compressing the limiting block 20 to move away from the sliding cavity 13. When the sliding plate 17 passes the limiting block 20, the sliding plate 17 can fall straight down, and the insertion rod 16 is inserted into the through hole 14 to lock the vertical latch 6 or the horizontal latch 8, increasing the energy required for violent destruction, and at the same time controlling the external alarm device to sound an alarm.

[0033] By incorporating a ring-shaped piezoelectric ceramic sensor 11 and a conductive post 12, an external alarm device can be activated when the vertical latch 6 and the horizontal latch 8 are subjected to violent prying, thereby locking the vertical latch 6 or the horizontal latch 8 and increasing the energy required for violent destruction.

[0034] By setting up the observation window 4, users can observe whether the marker line has moved into the observation window 4 and determine the extension length of the horizontal latch 8.

[0035] Example 2

[0036] A linkage locking mechanism for a gun cabinet, this embodiment is based on embodiment 1, with the following improvements, such as... Figure 5 As shown, the side wall of the sealing cover 2 is provided with two oil injection pipes 21. One end of the oil injection pipe 21 faces the meshing point of the rack 7 and the gear 5. One end of the rack 7 is provided with a sealing plug 22, which is sealed to the inner wall of the rack 7.

[0037] During the use of the gun cabinet, the user can pull out the sealing plug 22 while the gun cabinet is open, and inject oil into the meshing part of the rack 7 and gear 5 through the oil injection pipe 21 to ensure smooth meshing and rotation of the gear 5 and rack 7.

[0038] By setting up the oil injection pipe 21 and the sealing plug 22, it is convenient to inject oil at the meshing point of the rack 7 and the gear 5, so as to ensure smooth meshing and rotation of the gear 5 and the rack 7.

[0039] Working principle: During use, the inner wall of the side of the gun cabinet is provided with insertion holes for the vertical latch 6 and the horizontal latch 8. The user inserts the key into the mechanical anti-theft lock 3, and turns the mechanical anti-theft lock 3 to drive the gear 5 to rotate, which in turn drives the rack 7 to move, causing the vertical latch 6 to be inserted into the insertion holes at the top and bottom of the gun cabinet. At the same time, the actuating column drives the sliding ring 9 to move, causing the horizontal latch 8 to extend outward and be inserted into the insertion hole on the side wall of the gun cabinet. During the rotation of the mechanical anti-theft lock 3, the user can observe through the observation window 4 whether the indicator line has moved into the observation window 4 to determine the extension length of the horizontal latch 8. When external force is used to break the lock, either the vertical latch 6 or the horizontal latch 8 will be subjected to force, pushing the transmission column 12 to move and compress the piezoelectric ceramic sensor. 11. When the ring piezoelectric ceramic sensor 11 detects pressure, the electromagnet 18 is energized. The repulsive force between the electromagnet 18 and the magnetic piece 19 pushes the sliding plate 17 downward, squeezing the limiting block 20 to move away from the sliding cavity 13. When the sliding plate 17 passes the limiting block 20, the sliding plate 17 can fall straight down, and the insert rod 16 is inserted into the through hole 14 to lock the vertical latch 6 or the horizontal latch 8, increasing the energy required for violent destruction, and at the same time controlling the external alarm device to sound an alarm. During the use of the gun cabinet, the user can pull out the sealing plug 22 when the gun cabinet is open, and inject oil into the meshing part of the rack 7 and gear 5 through the oil injection pipe 21 to ensure smooth meshing and rotation of the gear 5 and rack 7.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
