The selected position indications in the specification, such as upper, lower, lateral, etc., also refer to the directly described and shown drawings and are transferred by meaning to the new positions when the positions are changed. Example 1
[0029] An intelligent gun cabinet facilitating fixing of a long gun and a use method thereof, as shown in the drawings, comprises a gun cabinet shell 1, an access mechanism 2 and a rotating hook taking mechanism 3, the gun cabinet shell 1 is provided with the access mechanism 2, the access mechanism 2 is used for accessing the long gun, the gun cabinet shell 1 is provided with the rotating hook taking mechanism 3, the hook taking mechanism 3 is used for adjusting the position of the long gun, facilitating people to store the long gun. Figures 1-5
[0030] As shown in the drawings, Figure 1 , Figure 2 and Figure 4 , the access mechanism 2 comprises a storage door plate 21, a limiting inclined plate 22, a gun taking door plate 23 and a gun taking inclined plate 24, the upper front side of the gun cabinet shell 1 is rotatably connected with the storage door plate 21, the front side inside the gun cabinet shell 1 is connected with the limiting inclined plate 22, the limiting inclined plate 22 is designed as high in front and low in back, the rear part of the limiting inclined plate 22 is provided with a buckle to prevent the long gun from sliding, the front side in the middle of the gun cabinet shell 1 is rotatably connected with the gun taking door plate 23, the front side inside the gun cabinet shell 1 is connected with the gun taking inclined plate 24, the gun taking inclined plate 24 is designed as low in front and high in back.
[0031] As shown in the drawings, Figure 1 ,Figure 2 , Figure 3 and Figure 5 As shown, the rotating hook mechanism 3 includes a rotating shaft 31, a rotating belt 32, a fixed rod 33, and a hook 34. The upper and middle parts of the gun cabinet shell 1 are rotatably connected to the rotating shaft 31. The left and right sides of the rotating shaft 31 are connected to the rotating belt 32. Six fixed rods 33 are evenly spaced between the left and right rotating belts 32. Each fixed rod 33 is connected to two hooks 34.
[0032] When long guns need to be stored, simply open the storage door panel 21, place the long gun on the limiting ramp 22, and the long gun will slide into the gun cabinet through the limiting ramp 22 and be locked in the latch. Then, the rotating shaft 31 rotates clockwise to drive the rotating belt 32 to rotate. The fixing rod 33 on the rotating belt 32 will drive the hook 34 to rotate together. When the hook 34 rotates to the latch of the limiting ramp 22, it will hook the long gun at the latch. When more long guns need to be stored, simply continue to rotate the rotating shaft 31 clockwise, and the remaining hooks 34 can store the remaining long guns. Then, close the gun retrieval door panel 23. When it is necessary to retrieve the spear, simply open the spear retrieval panel 23 and rotate the pivot 31 counterclockwise. When the spear on the hook 34 is rotated to the spear retrieval ramp 24, continue to rotate the pivot 31 counterclockwise. The spear retrieval ramp 24 will then hold the spear and slide it out. When it is necessary to retrieve the spear again, simply continue to rotate the pivot 31 counterclockwise. Finally, close the spear retrieval panel 23. Example 2
[0033] Based on Example 1, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, it also includes a rotation adjustment mechanism 4, which includes a rotation handle 41, a worm gear 42 and a worm wheel 43. The rotation handle 41 is rotatably connected to the right side of the gun cabinet shell 1, the worm gear 42 is connected to the rear side of the rotation handle 41, and the worm wheel 43 is connected to the outer side of the rotating shaft 31 in the middle. The worm wheel 43 meshes with the worm gear 42.
[0034] When the handle 41 is rotated clockwise, the worm gear 42 on the handle 41 drives the worm wheel 43 to rotate clockwise, which in turn drives the shaft 31 to rotate clockwise. Similarly, when the handle 41 is rotated counterclockwise, the shaft 31 is driven to rotate counterclockwise, thus enabling more precise and effortless control of the shaft 31's rotation.
[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 9As shown, the switch mechanism 5 includes a rotating gear 51 and a transmission rod 52. The rotating gear 51 is rotatably connected to the right part of the shell 1, and a password lock is installed on the rotating gear 51. The transmission rod 52 is slidably connected to the shell 1, and the upper side of the transmission rod 52 has a toothed pattern. The toothed pattern on the upper side of the transmission rod 52 is engaged with the rotating gear 51. The upper part of the transmission rod 52 clamps the storage door plate 21, and the middle part of the transmission rod 52 clamps the gun taking door plate 23.
[0036] When it is necessary to control the opening and closing of the shell through the password lock, the password lock is only needed to be unlocked, and then the password lock is controlled to rotate, thereby driving the rotating gear 51 to rotate, and then driving the transmission rod 52 to move upward through the toothed pattern. When the transmission rod 52 moves upward, the storage door plate 21, the gun taking door plate 23 and the ammunition magazine 62 are no longer clamped, and they can be opened at any time for storage and taking. When the storage and taking are finished, the storage door plate 21, the gun taking door plate 23 and the ammunition magazine 62 are only needed to be closed, and then the password lock is reversed to rotate, thereby driving the transmission rod 52 to move downward through the toothed pattern, clamping the storage door plate 21, the gun taking door plate 23 and the ammunition magazine 62, and blocking the storage door plate 21, the gun taking door plate 23 and the ammunition magazine 62 from being pulled out.
[0037] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 8 , the ammunition gravity sensing mechanism 6 includes a first pressure spring 61, an ammunition magazine 62 and a scale plate 63. The ammunition magazine 62 is slidably connected to the lower part of the shell 1. The left side of the ammunition magazine 62 is connected with the scale plate 63. The left and right sides of the lower part of the ammunition magazine 62 are connected with the front and rear first pressure springs 61 between the shell 1. When the shell is in the locked state, the lower part of the transmission rod 52 clamps the ammunition magazine 62, preventing the ammunition magazine 62 from being pulled out.
[0038] When it is necessary to know the amount of ammunition in the ammunition magazine 62, the ammunition is only needed to be put into the ammunition magazine 62. The gravity of the ammunition magazine 62 drives the scale plate 63 to move downward. At this time, the first pressure spring 61 is in a compressed state. When the ammunition in the ammunition magazine 62 is taken out, the gravity of the ammunition magazine 62 becomes smaller, and the elastic force of the first pressure spring 61 drives the scale plate 63 to move upward, thereby displaying the amount of ammunition in the ammunition magazine 62 through the scale plate 63.
[0039] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 9 and Figure 10As shown, it also includes a tamper-proof alarm mechanism 7, which includes an alarm 71, a disassembly sensing rod 72, a second pressure spring 73, an alarm switch 74 and a sliding magnet 75. The alarm 71 is connected to the upper side of the cartridge cabinet shell 1. The disassembly sensing rod 72 is slidingly connected to the inner wall of the front side of the cartridge cabinet shell 1. The second pressure spring 73 is connected between the disassembly sensing rod 72 and the cartridge cabinet shell 1. The two sliding magnets 75 are slidingly connected to the left part of the cartridge cabinet shell 1. The upper sliding magnet 75 is in contact with the rear side of the disassembly sensing rod 72. The storage door plate 21 sucks the upper sliding magnet 75. The gun taking door plate 23 sucks the lower sliding magnet 75. The alarm switch 74 is connected to the upper part of the cartridge cabinet shell 1. The alarm switch 74 is used to control the alarm 71. The upper part of the disassembly sensing rod 72 moves to the left and touches the alarm switch 74. The upper part of the disassembly sensing rod 72 is in contact with the transmission rod 52.
[0040] In the normal locking state, the left side of the storage door plate 21 and the gun taking door plate 23 will suck the sliding magnet 75. When the code lock is not opened, the storage door plate 21 or the gun taking door plate 23 is opened. The door plate will pull the disassembly sensing rod 72 to move outward through the sliding magnet 75. The upper side of the disassembly sensing rod 72 will touch the alarm switch 74. When the code lock is normally opened, the code lock will drive the transmission rod 52 to move upward through the rotating gear 51. The upward movement of the transmission rod 52 will block the disassembly sensing rod 72, preventing the disassembly sensing rod 72 from touching the alarm switch 74. When the storage door plate 21 and the gun taking door plate 23 are opened, no alarm will be triggered.
[0041] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from the present disclosure will appreciate that various other embodiments can be made without departing from the scope of the present application. Therefore, the scope of the present application should be limited only by the appended claims.
