The sliding clamping plates 6 are slidably connected to the first fixed guide rails 5. The sliding clamping plates 6 are slidably connected to the housing 1. The first fixed guide rails 5 can guide the sliding clamping plates 6. The straight racks 7 are connected to the sides of the sliding clamping plates 6 close to each other. The straight racks 7 are meshed with the first full gear 4. The gear can make the straight racks 7 move. The sliding mechanism 8 is arranged on the housing 1, and the rotating mechanism 9 is arranged on the housing 1.

[0035] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown in the figure, the sliding mechanism 8 includes a second fixed guide rail 81, a horizontal lock bolt 82, a dial post 83 and a connecting plate 84. The second fixed guide rail 81 is connected to the rear part of the housing 1. The horizontal lock bolts 82 are slidably connected to the upper and lower sides of the second fixed guide rail 81. The horizontal lock bolts 82 can lock the gun cabinet. The connecting plate 84 is connected between the two horizontal lock bolts 82. The dial post 83 is connected to the first full gear 4. The dial post 83 is slidably connected to the connecting plate 84. The dial post 83 can make the connecting plate 84 move.

[0036] As Figure 3 , Figure 4 and Figure 7As shown, the rotating mechanism 9 includes a first fixed frame 91, a second fixed frame 92, a sliding locking member 93, a first rotating shaft 931, an annular rack 94, a second rotating shaft 95, a second full gear 96, a missing gear 97, a toggle frame 98 and an annular locking member 99, the left side of the transverse latch 82 away from each other is connected to the second fixed frame 92, the upper and lower sides of the left part of the shell 1 are connected to the first fixed frame 91, the upper and lower sides of the left part of the shell 1 are rotatably connected to the first rotating shaft 931, the first rotating shaft 931 is located in the middle of the left side of the adjacent first fixed frame 91, the first rotating shaft 931 is connected to the sliding locking member 93, the sliding locking member 93 and the first fixed frame 91 are slidably connected, the rear side of the sliding locking member 93 is connected to the annular rack 94, the annular rack 94 can make the sliding locking member 93 rotate, The upper rear side of the first fixed frame 91 on the side is rotatably connected to the second rotating shaft 95, and the lower rear side of the first fixed frame 91 on the lower side is also rotatably connected to the second rotating shaft 95. The second rotating shaft 95 is connected to a second full gear 96, and the second full gear 96 and the annular rack 94 are meshed with each other. The second full gear 96 can make the annular rack 94 rotate. The upper and lower sides of the left part of the cover plate 3 are rotatably connected to a toggle frame 98, and the toggle frame 98 and the second fixed frame 92 are both slidably and rotatably connected, and the second fixed frame 92 can make the toggle frame 98 rotate. The front part of the toggle frame 98 is connected with a missing gear 97, and the missing gear 97 and the second full gear 96 are meshed with each other. The front side of the toggle frame 98 is connected with an annular locking piece 99, and the gun cabinet can be locked with the cooperation of the sliding locking piece 93 and the annular locking piece 99.

[0037] When people need to lock the gun cabinet, they can use this mechanism to operate. First, install the cover plate 3 on the gun cabinet, and then use the key to rotate the lock cylinder 2 counterclockwise, thereby driving the first full gear 4 to rotate counterclockwise. At this time, the spur rack 7 and the sliding card plate 6 on the left will move downward, while the spur rack 7 and the sliding card plate 6 on the right will move upward. In this way, the shell 1 can be locked. At the same time, when the first full gear 4 rotates counterclockwise, the first full gear 4 will also drive the lever 83 to rotate counterclockwise. At this time, the lever 83 will make the connecting plate 84 and the horizontal latch 82 move to the left, so that the gun cabinet can be further locked. At the same time, the horizontal latch 82 will also drive the second fixing frame 92 to move to the left, and then The upper toggle frame 98, the missing gear 97 and the annular locking piece 99 rotate clockwise, and the missing gear 97 on the upper side also causes the second full gear 96 and the second rotating shaft 95 on the upper side to rotate counterclockwise, and then the upper annular rack 94 and the upper sliding locking piece 93 rotate counterclockwise. At this time, the upper sliding locking piece 93 and the upper annular locking piece 99 are in a fitted state, so that the upper part of the housing 1 is locked. At the same time, when the second fixing frame 92 on the lower side moves to the left, the lower toggle frame 98, the missing gear 97 and the annular locking piece 99 rotate counterclockwise, and the missing gear 97 also causes the second full gear 96 and the second rotating shaft 95 on the lower side to rotate clockwise, and then the lower annular rack 94 and the upper sliding locking piece 93 rotate counterclockwise. The rack 94 and the sliding locking piece 93 on the lower side rotate clockwise. At this time, the sliding locking piece 93 on the lower side and the annular locking piece 99 on the lower side are in a fitted state, so that the lower part of the shell 1 is locked. In this way, the gun cabinet can be triple-bolted, thereby improving the protection of the latch mechanism. When people do not need to lock the gun cabinet, the lock cylinder 2 is rotated clockwise to reset by the key, and then the first full gear 4 is driven to rotate clockwise. At this time, the spur rack 7 and the sliding card plate 6 on the left side will move upward to reset, and the spur rack 7 and the sliding card plate 6 on the right side will move downward to reset. At this time, the first full gear 4 will also drive the lever 83 to rotate clockwise to reset, and then the connecting plate 84 and the horizontal latch 82 move right to reset. At the same time, the horizontal latch 82 will also drive the second fixed frame 92 to move rightward and reset, and then the upper toggle frame 98, the missing gear 97 and the annular locking member 99 will rotate counterclockwise to reset, thereby causing the upper second full gear 96 and the second rotating shaft 95 to rotate clockwise to reset, and then the upper annular rack 94 and the upper sliding locking member 93 will rotate clockwise to reset. At this time, the upper sliding locking member 93 and the upper annular locking member 99 are in a separated state. At the same time, when the lower second fixed frame 92 moves rightward and resets, the lower toggle frame 98, the missing gear 97 and the annular locking member 99 will rotate clockwise to reset, causing the lower second full gear 96 and the second rotating shaft 95 to rotate counterclockwise to reset.Then, make the lower annular rack 94 and the lower sliding locking member 93 rotate counterclockwise to reset. At this time, the lower sliding locking member 93 and the lower annular locking member 99 are in a separated state. Repeating the above operations can lock the gun cabinet, and the gun cabinet can be further locked by the cooperation between the sliding locking member 93 and the annular locking member 99, thereby improving the protection performance of this latch mechanism and making the guns in the gun cabinet safer.

[0038] Embodiment 2

[0039] Based on Embodiment 1, as Figure 4 and Figure 10 shown, it further includes a limiting mechanism 10. The limiting mechanism 10 includes a fixed frame 101, a limiting member 102, and a first telescopic spring 103. The middle part of the right side of the outer shell 1 is fixedly connected with the fixed frame 101. The upper and lower sides of the fixed frame 101 are both slidably connected with the limiting member 102. The limiting member 102 can be inserted into the horizontal latch 82 to limit the horizontal latch 82. A first telescopic spring 103 is connected between the limiting member 102 and the second fixed guide rail 81, and the first telescopic spring 103 can make the limiting member 102 reset.

[0040] As Figure 4 and Figure 11 shown, it further includes a clamping mechanism 11. The clamping mechanism 11 includes a fixed rod 104, an L-shaped member 111, a first fixed block 112, and a limiting block 113. The right side of the inner bottom wall of the outer shell 1 is welded with the first fixed block 112. The first fixed block 112 is rotatably connected with the L-shaped member 111. The upper side of the L-shaped member 111 is connected with the inner top wall of the outer shell 1. The right side of the L-shaped member 111 is connected with the limiting block 113. The limiting block 113 is clamped with the two limiting members 102, and the limiting block 113 can limit the limiting members 102. The rear side of the upper right part of the outer shell 1 is connected with the fixed rod 104, and the fixed rod 104 contacts the L-shaped member 111. The fixed rod 104 can break the L-shaped member 111.

[0041] Since firearms are stored in the gun cabinet, it is inevitable that some illegal elements will damage the outer shell 1 and steal the firearms inside the gun cabinet. Therefore, the cross-lock bolt 82 can be limited by the limiting mechanism 10 and the clamping mechanism 11 to enhance the security of this lock bolt mechanism. Initially, the limiting piece 102 is limited by the limiting block 113, and the first telescopic spring 103 is in a stretched state. When the outer shell 1 is damaged, the outer shell 1 will deform, and then the fixing rod 104 will move backward. Since the fixing rod 104 contacts the thinnest position of the L-shaped part 111, when the fixing rod 104 moves backward, the fixing rod 104 will break the L-shaped part 111 into two halves. At this time, the lower half of the L-shaped part 111 will rotate, and then drive the limiting block 113 to rotate, so that the limiting block 113 is separated from the limiting piece 102. At this time, under the action of the first telescopic spring 103, the limiting piece 102 will move toward the side away from each other. At this time, the limiting piece 102 will be stuck into the cross-lock bolt 82, thereby limiting the cross-lock bolt 82. In this way, even if people use the key, they cannot open the cross-lock bolt 82.

[0042] As Figure 4 , Figure 12 , Figure 13 and Figure 14 shown, it further includes an alarm mechanism 12. The alarm mechanism 12 includes a third fixing bracket 121, a battery 122, an alarm 123, a slide plate 124, a sliding switch 125, a second telescopic spring 126, and a fixed switch 127. The right side of the inner bottom wall of the outer shell 1 is fixedly connected with a fixed switch 127. The upper side of the left part of the fixed switch 127 is electrically connected with an alarm 123, and the alarm 123 can emit an alarm. The right inner wall of the lower part of the outer shell 1 is connected with a third fixing bracket 121, and a battery 122 is placed on the third fixing bracket 121. The battery 122 can supply power to the third fixing bracket 121. The rear part of the third fixing bracket 121 is slidably connected with a sliding switch 125. The sliding switch 125 and the rear part of the alarm 123 are slidably connected. The sliding switch 125 contacts the fixed switch 127 and can supply power to the alarm 123. A second telescopic spring 126 is connected between the upper part of the sliding switch 125 and the third fixing bracket 121. The second telescopic spring 126 can reset the sliding switch 125. The front side of the lower part of the L-shaped part 111 is rotatably connected with a slide plate 124. The slide plate 124 and the rear part of the alarm 123 are slidably connected. The slide plate 124 contacts the lower side of the sliding switch 125 and the upper side of the fixed switch 127.

[0043] When the outer shell 1 is damaged and an alarm needs to be issued, the alarm mechanism 12 can be used for operation. Initially, the sliding switch 125 is in the uppermost position, and the second telescopic spring 126 is in a stretched state. When the lower part of the L-shaped part 111 drives the sliding plate 124 to rotate and separate from the alarm 123, under the action of the second telescopic spring 126, the sliding switch 125 will move downward and contact the fixed switch 127, so that the alarm 123 can be powered. At this time, the alarm 123 will issue an alarm, thereby informing the staff that the outer shell 1 is being damaged, and the staff can take corresponding measures in time.

[0044] As Figure 1 and Figure 15 shown, it further includes a covering mechanism 13. The covering mechanism 13 includes a second fixing block 131, a shielding cover 132 and a connecting pin 133. The second fixing block 131 is welded to the front side of the outer shell 1. The second fixing block 131 is connected with a connecting pin 133, and the shielding cover 132 is rotatably connected to the connecting pin 133. The shielding cover 132 can cover the lock core 2.

[0045] As Figure 1 and Figure 15 shown, it further includes a connecting block 14. Two connecting blocks 14 are connected to the lower front side of the shielding cover 132. The two connecting blocks 14 are distributed on the upper and lower sides. The connecting block 14 facilitates people to rotate the shielding cover 132.

[0046] Since the lock core 2 is exposed in the air for a long time, the lock core 2 is prone to wear and is also easily broken. Therefore, the covering mechanism 13 can be used to protect the lock core 2. When people need to rotate the lock core 2, first rotate the shielding cover 132 open through the connecting block 14, and then people can rotate the lock core 2 with the key. When people do not need to rotate the lock core 2, reverse the shielding cover 132 to reset. At this time, the shielding cover 132 will cover the lock core 2. Repeating the above operations can cover the lock core 2, prevent the lock core 2 from being damaged, and also reduce the wear of the lock core 2.

[0047] The above embodiments only represent the preferred embodiments of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations, improvements and substitutions can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
