Description

Technical Field

[0001] This utility model relates to the field of magazine loading technology, specifically to a dual-mode magazine loading device. Background Technology

[0002] A loader is a device used to assist in loading ammunition, primarily used in military and shooting-related fields. Its purpose is to improve loading efficiency and reduce operational burden, thus minimizing physical labor during combat, accelerating loading speed, and increasing firing efficiency. However, traditional manual loading equipment generally involves manually pressing the ammunition into the belt clip using a manual belt loader. This requires manual alignment of the belt and ammunition using mechanical levers or rotating handles, which can lead to hand fatigue over extended periods. While patent application CN117029562 A discloses a dual-cam propulsion type loader with a support base, allowing users to rotate the drive shaft via a foot pedal or manually crank the pedal without the support base, it still relies on manual labor, resulting in fatigue over time and minimal efficiency improvement.

The driving bevel gear is fixedly connected to the drive shaft, and the drive gear is slidably connected to the drive shaft. A return spring is provided between the drive gear and the drive shaft. When the hand crank is not inserted, the drive gear is in a position of meshing with the driving gear under the elastic force of the return spring. When the hand crank is inserted and pressed in forcefully, the drive gear separates from the driving gear. The DC geared motor is installed inside the frame. The driving gear is installed on the rotating shaft of the DC geared motor and meshes with the drive gear. The driving bevel gear meshes with a driven bevel gear. The driven bevel gear is rotatably connected to the frame. The driven bevel gear drives the reciprocating screw to rotate through gear set one. The reciprocating screw is rotatably connected to the frame. The reciprocating screw drives the spring chain wheel to rotate through gear set two. The reciprocating screw and the slide rail are transmitted through gear set one.

[0006] A funnel is provided above the frame, and a vibration device is provided inside the funnel. Detection devices are provided below the funnel and in front of and behind the spring chain wheel.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0018] Example 1, in conjunction with Appendix Figures 1-5 A dual-mode ammunition belt loader includes a frame 1, a drive shaft 2, a drive gear 3, a drive bevel gear 4, a reciprocating screw 5, a slide rail 6, a DC geared motor 7, and a drive gear 8.

[0019] The drive shaft 2 is rotatably connected to the frame 1. One end of the drive shaft 2 extends from one side of the frame 1 and is equipped with a hand crank connector 9. The driving bevel gear 4 is fixedly connected to the drive shaft 2, and the drive gear 3 is slidably connected to the drive shaft 2. A return spring is provided between the drive gear 3 and the drive shaft 2. When the hand crank is not inserted, the drive gear 3 is in a position of meshing with the driving gear 8 under the action of the return spring. When the hand crank is inserted and pressed in forcefully, the drive gear 3 separates from the driving gear 8. The DC geared motor 7 is installed inside the frame 1. The driving gear 8 is installed on the rotating shaft of the DC geared motor 7 and meshes with the transmission gear 3. The driving bevel gear 4 meshes with the driven bevel gear 15. The driven bevel gear 15 is rotatably connected to the frame 1. The driven bevel gear 15 drives the reciprocating screw 5 to rotate through the gear set 10. The reciprocating screw 5 is rotatably connected to the frame 1. The reciprocating screw 5 drives the spring chain wheel 12 to rotate through the gear set 16. The reciprocating screw 5 and the slide rail 6 are transmitted through the gear set 10.

[0020] A funnel 11 is provided above the frame 1, and a vibration device is provided inside the funnel 11. When the reciprocating screw moves, the vibration device works to prevent the bullet from jamming and to allow the bullet to fall smoothly from the funnel 11. A bullet detection probe 13 is provided below the funnel 11. A bullet chain detection probe 14 is provided in front of and behind the bullet chain wheel 12.

[0021] The frame 1 is equipped with a preset counting controller, relays, power supply, and switching buttons.

[0022] In specific implementation of this utility model, when manual operation is selected, the hand crank is connected to the hand crank connector 9. At this time, the transmission gear 3 is separated from the driving gear 8. When the hand crank is turned to drive the transmission shaft 2 to rotate, the transmission gear 3 will not drive the driving gear 8 to rotate. Therefore, in manual mode, the shaft of the DC geared motor 7 will not rotate. The projectile is placed in the funnel 11. By turning the hand crank, the transmission shaft 2 is driven to rotate, the driving bevel gear 4 rotates, which drives the driven bevel gear 15 to rotate. Through the gear set 10, the reciprocating screw 5 rotates, and the slide rail 6 moves. The reciprocating screw 5 drives the slider connected to it to push the projectile into the sprocket 12. At the same time, the projectile detection probe 13 accumulates the number of projectiles pressed. The reciprocating screw 5 rotates to drive the gear set 2 16. The gear set 2 16 drives the sprocket 12 to rotate, and a new round of loading can be carried out. When the electric operation is selected, there is no need to connect the hand crank. The number of bullets to be loaded can be preset on the preset device. Place the bullets into the funnel 11, place the bullet chain on the bullet chain wheel 12, press the start switch, and after the bullet detection probe 13 detects it and the bullet chain detection probe 14 detects it, the DC geared motor 7 will work. At the same time, the bullet detection probe 13 accumulates the number of bullets loaded, driving the transmission shaft 2 to rotate. The bullet loading process is the same as above. When the bullet detection probe 13 reaches the preset number, the DC motor stops working. When the bullet chain detection probe 14 detects that the bullet chain wheel 12 is full or empty, the DC geared motor 7 will also stop working.

[0023] The frame 1 is equipped with a lithium battery and a 24V power interface. The DC geared motor 7, the projectile detection probe 13, and the bullet belt detection probe 14 can be powered by either the lithium battery or an external power source.
