Description

Technical Field

[0001] This invention relates to a firearms and ammunition selection shelf, and more particularly to an intelligent firearms and ammunition selection shelf for use by the People's Armed Police. Background Technology

[0002] Members of police, military, and shooting associations often need to use firearms and ammunition to perform official duties or conduct shooting training. Improper use of firearms and ammunition can have serious consequences. In order to avoid the use of firearms and ammunition during off-duty or training periods, it is necessary to strictly control the access to firearms and ammunition. Therefore, firearms and ammunition cabinets are needed to store and control firearms and ammunition.

[0003] The traditional method of storing firearms and ammunition involves the supervisor placing the ammunition into a protective cabinet and then sealing the cabinet to prevent loss. During this process, when the cabinet is shaken by external forces, the ammunition may fall to the bottom, causing some damage. In addition, the protective cabinet is fixed in a designated location and is inconvenient to move. When the ammunition is urgently needed, the supervisor needs to open the lock, which takes a lot of time and involves cumbersome procedures.

[0004] To address this, we designed an intelligent shelf for selecting firearms and ammunition for armed police officers on duty, which automatically clamps the ammunition, automatically opens the blockade, and facilitates movement. Summary of the Invention

[0005] In order to overcome the shortcomings of traditional ammunition selection shelves that cannot automatically clamp ammunition, cannot automatically open the blockage, and are inconvenient to move, this invention provides an intelligent ammunition selection shelf for armed police on duty that can automatically clamp ammunition, automatically open the blockage, and is easy to move.

[0073] It also includes a control box 2, which is installed in the middle of the left side of the shelf 1. The control box 2 contains a switching power supply, a control module, and a power module. The switching power supply provides power to the intelligent shelf 1 for the armed police to select ammunition for their deployment. The output of the switching power supply is electrically connected to the power module. The power module is connected to the main power switch via a circuit. The control module and the power module are electrically connected. The control module is connected to a DS1302 clock circuit and a 24C02 circuit.

The first electric push rod 41, the second electric push rod 72, the electromagnet 81, and the electromagnetic lock 83 are all connected to the control module via a relay control module.

[0074] The working principle of this invention is as follows: When people want to store firearms and ammunition, they can use this intelligent firearms and ammunition selection shelf 1 for armed police deployment. First, the user presses the main power switch to power on the device. The user then pulls the fixing mechanism 6 upwards. After the fixing mechanism 6 moves upwards and disengages from the placement mechanism 5, the user places the firearm on the placement mechanism 5. After the firearm is placed, the user releases the fixing mechanism 6, causing it to move downwards and contact the placement mechanism 5, thus clamping the firearm and storing it. When the user wants to retrieve the firearm, the user presses the picking mechanism 4, causing the control module to control the picking mechanism 4 to operate for three seconds. The picking mechanism 4 drives the placement mechanism 5 to rotate. After the placement mechanism 5 rotates and contacts the fixing mechanism 6, it drives the fixing mechanism 6 to move upwards. After three seconds, the control module controls the... After the feeding mechanism 4 is stationary and the fixing mechanism 6 moves upward to detach from the gun, the user removes the gun. When the distance between the placement mechanism 5 and the gun reaches the preset value of the placement mechanism 5, the control module controls the feeding mechanism 4 to rotate in the opposite direction for three seconds. The feeding mechanism 4 drives the placement mechanism 5 to rotate in the opposite direction. After the placement mechanism 5 rotates in the opposite direction to detach from the fixing mechanism 6, the fixing mechanism 6 moves downward to return to its original position. At the same time as the user presses the feeding mechanism 4, the control module controls the discharging mechanism 7 to move forward for three seconds. After three seconds, the control module controls the discharging mechanism 7 to remain stationary for five minutes. The user then puts the bullet into the discharging mechanism 7, which stores the bullet. After five minutes, the control module controls the discharging mechanism 7 to move backward for three seconds. After three seconds, the control module controls the discharging mechanism 7 to remain stationary. The user then presses the main power switch again to turn off the power to the device.

[0075] After the user places the gun on the feeding plate 3, the user presses the start button 43, causing the control module to control the piston rod of the first electric push rod 41 to shorten upwards for three seconds. The piston rod of the first electric push rod 41 pulls the pull rope 42, which drives the feeding plate 3 to rotate. After three seconds, the control module controls the piston rod of the first electric push rod 41 to stop. At this time, the feeding plate 3 is in an inclined state. The user places the gun, so that the feeding plate 52 stores the gun. After the gun is stored and the user takes out the required gun, when the distance between the feeding mechanism 5 and the gun reaches the preset value of the feeding mechanism 5, the control module controls the piston rod of the first electric push rod 41 to extend downwards for three seconds. The piston rod of the first electric push rod 41 pulls the pull rope 42, which drives the feeding plate 3 to rotate in the opposite direction. After three seconds, the control module controls the piston rod of the first electric push rod 41 to stop. At this time, the feeding plate 3 is in a stable state.

[0076] After the user places the gun on the placement plate 52, the weight of the gun causes the placement plate 52 to move downwards, compressing the first spring 51. The placement plate 52 then causes the first distance sensor 53 to move downwards. When the feeding plate 3 rotates, it causes the first spring 51, the placement plate 52, and the first distance sensor 53 to rotate, resulting in the gun being tilted. After the user removes the gun from the placement plate 52, when the distance between the first distance sensor 53 and the gun reaches the preset value of the first distance sensor 53, the control module controls the piston rod of the first electric push rod 41 to extend downwards for three seconds. The piston rod of the first electric push rod 41 pulls the pull rope 42, which causes the feeding plate 3 to rotate in the opposite direction. After three seconds, the control module controls the piston rod of the first electric push rod 41 to stop. At this time, the feeding plate 3 is in a stable state.

[0077] After the gun is placed on the placement plate 52, the clamping plate 61 clamps the gun. When the placement plate 3 rotates, it drives the first spring 51, the placement plate 52, and the first distance sensor 53 to rotate. Simultaneously, the rear side of the placement plate 52 moves upward, pushing the clamping plate 61 upward. The clamping plate 61 moves upward on the connecting rod 62, compressing the second spring 63, thus releasing the clamping plate 61 from the gun. The user then removes the gun from the placement plate 52. When the distance between the first distance sensor 53 and the gun... When the distance reaches the preset value of the first distance sensor 53, the control module controls the piston rod of the first electric push rod 41 to extend downward for three seconds. The piston rod of the first electric push rod 41 pulls the pull rope 42, and the pull rope 42 drives the feeding plate 3 to rotate in the opposite direction. The feeding plate 3 drives the first spring 51, the placement plate 52 and the first distance sensor 53 to rotate in the opposite direction. After the placement plate 52 rotates in the opposite direction and disengages from the clamping plate 61, the second spring 63 resets, thereby driving the clamping plate 61 and the connecting rod 62 to move downward. After three seconds, the control module controls the piston rod of the first electric push rod 41 to stop.

[0078] When the distance between the first distance sensor 53 and the shelf 1 reaches the preset value of the first distance sensor 53, the control module controls the piston rod of the second electric push rod 72 to extend forward for three seconds. The piston rod of the second electric push rod 72 drives the material box 71 to move forward. After three seconds, the control module controls the piston rod of the second electric push rod 72 to remain stationary for five minutes. Then, the user puts the bullet into the material box 71, so that the material box 71 stores the bullet. After five minutes, the control module controls the piston rod of the second electric push rod 72 to shorten backward for three seconds. The piston rod of the second electric push rod 72 drives the material box 71 to move backward. After three seconds, the control module controls the piston rod of the second electric push rod 72 to remain stationary.

[0079] After the user presses the start button 43, the control module energizes the electromagnet 81. The repulsive force generated by the electromagnet 81 repels the magnetic door 82, causing the electromagnet 81 to move to the left. The repulsive force drives the magnetic door 82 to move, which in turn drives the electromagnetic lock 83 to move to the right. The electromagnet 81 then drives the second distance sensor 84 to move to the left. The electromagnet 81 and the magnetic door 82 cause the roller 85 to rotate. When the distance between the second distance sensor 84 and the shelf 1 reaches the preset value of the second distance sensor 84, the control module de-energizes the electromagnet 81, and the electromagnet 81 stops generating repulsive force. This causes the electromagnet 81 and the magnetic door 82 to open the interior of the shelf 1, allowing the user to remove the gun from the placement plate 52. When the first distance sensor... When the distance between the first distance sensor 53 and the gun reaches the preset value of the first distance sensor 53, the control module controls the electromagnet 81 to be energized. The magnetic force generated by the electromagnet 81 attracts the magnetic block door 82, causing the electromagnet 81 to move to the right. The electromagnet 81 drives the second distance sensor 84 to move to the right. The magnetic force drives the electromagnetic lock 83 and the magnetic block door 82 to move to the left. The electromagnet 81 and the magnetic block door 82 drive the roller 85 to rotate in the opposite direction. When the distance between the second distance sensor 84 and the shelf 1 reaches another preset value of the second distance sensor 84, the control module controls the electromagnet 81 to be de-energized. The electromagnet 81 stops generating magnetic force, and the electromagnetic lock 83 locks the electromagnet 81 and the magnetic block door 82. The above actions stop, thereby closing the inside of the shelf 1.

[0080] To facilitate the movement of shelf 1, the user rotates the pivot 91, which drives the wheel 93 to rotate. The third spring 92 twists and deforms. After the wheel 93 contacts the ground, the user stops rotating the pivot 91. Then, the user pushes the shelf 1, and the wheel 93 contacts the ground, thus driving the wheel 93 to rotate. The wheel 93 drives the pivot 91, the third spring 92, and the shelf 1 to move. After the shelf 1 moves to the designated position, the user stops pushing the shelf 1, and the wheel 93 stops rotating. Then, the user releases the pivot 91, and the third spring 92 returns to its original position, thus driving the pivot 91 and the wheel 93 to rotate in the opposite direction to return to their original positions.

All equivalent substitutions made within the principles of the present invention should be included within the scope of protection of the present invention.
