[0020] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] Example 1: Please refer to Figure 1 - Figure 4 , an electric stacker counterweight device of this embodiment includes a stacker body 1 and a battery module 2, one end of the stacker body 1 is provided with a motor 3, one end of the motor 3 is fixedly connected to a screw rod 4, one end of the screw rod 4 is fixedly connected to a sliding seat 5, the top of the sliding seat 5 is fixedly connected to a movable box 6, the battery module 2 is located inside the movable box 6, one side of the movable box 6 is provided with a pull block 9, one side of the pull block 9 is fixedly connected to a bidirectional threaded rod 10, both ends of the bidirectional threaded rod 10 are threadedly connected to two threaded seats 11, the tops of the two threaded seats 11 are fixedly connected to two clamping blocks 12, and the battery module 2 is located between the two clamping blocks 12;

[0022] When the counterweight of the electric stacker needs to be adjusted, the motor 3 is started, the motor 3 drives the screw rod 4 to rotate, the screw rod 4 drives the sliding seat 5 to move, the sliding seat 5 drives the movable box 6 to move, and the movable box 6 drives the battery module 2 to move, thereby adjusting the internal counterweight of the stacker by moving the battery module 2. By using the weight of the battery module 2 inside the electric stacker for counterweight, the use of counterweight blocks can be reduced, thereby reducing costs.

[0023] Secondly, when the battery module 2 needs to be disassembled for replacement and maintenance, the pulling block 9 is rotated, and the pulling block 9 will drive the bidirectional threaded rod 10 to rotate. The bidirectional threaded rod 10 will drive the two threaded seats 11 to move. The threaded seats 11 will move along the inside of the movable groove 13. At the same time, the threaded seats 11 will drive the clamping block 12 to move, so that the two clamping blocks 12 are separated from each other, thereby facilitating the removal of the battery module 2.

[0024] Furthermore, two movable grooves 13 are processed inside the movable box 6, and the threaded seat 11 is movably connected to the inside of the movable groove 13. By providing the movable groove 13, the threaded seat 11 will move along the inside of the movable groove 13, thereby limiting the movement of the threaded seat 11 and keeping the clamping block 12 in a stable state when moving;

[0025] Furthermore, the interior of the stacker body 1 is fixedly connected to two slide bars 8, and the exterior of the slide bars 8 is slidably connected to a slider 7. The top of the slider 7 is fixedly connected to the bottom of the movable box 6. When the movable box 6 moves, the movable box 6 will drive the slider 7 to move, so that the slider 7 slides along the exterior of the slide bars 8. By providing the slide bars 8, the slide bars 8 will limit the movement of the movable box 6, so that the movable box 6 remains stable during movement.

[0026] Furthermore, the bidirectional threaded rod 10 is rotatably connected to the bottom of the movable box 6. A rotation groove 14 is processed on one side of the movable box 6. One end of the bidirectional threaded rod 10 is rotatably connected to the inside of the rotation groove 14. When the pull block 9 rotates, it will drive one end of the bidirectional threaded rod 10 to rotate around the inside of the rotation groove 14.

A plurality of limiting grooves 18 are processed on one side of the movable box 6, and the limiting ring 17 is plug-connected to the inside of the limiting groove 18. When the pulling block 9 needs to be rotated, the movable ring 15 is pulled outward, and the movable ring 15 will drive the connecting rod 16 to move outward, and the connecting rod 16 will drive the limiting ring 17 to move outward, so that the limiting ring 17 is disengaged from the inside of the limiting groove 18, so that the pulling block 9 can be rotated. By providing the connecting rod 16 and the limiting ring 17, the pulling block 9 will be limited to prevent the two-way threaded rod 10 from rotating and loosening the two clamping blocks 12;

[0028] Furthermore, a return spring 19 is provided on the outside of the connecting rod 16, one end of the return spring 19 is fixedly connected to one side of the pull block 9, and the other end of the return spring 19 is fixedly connected to the inner side of the limit ring 17. By providing the return spring 19, when the movable ring 15 is pulled, the connecting rod 16 will drive the return spring 19 to compress, and when the movable ring 15 is released, the return spring 19 will reset and extend, and the return spring 19 will drive the limit ring 17 to move, so that the limit ring 17 is inserted into the inside of the limit groove 18 to limit the pull block 9.

[0029] Working principle: By starting the motor 3, the motor 3 will drive the screw rod 4 to rotate, the screw rod 4 will drive the sliding seat 5 to move, the sliding seat 5 will drive the movable box 6 to move, and the movable box 6 will drive the battery module 2 to move, thereby adjusting the internal counterweight of the forklift by moving the battery module 2. By rotating the pull block 9, the pull block 9 will drive the bidirectional threaded rod 10 to rotate, and the bidirectional threaded rod 10 will drive the two threaded seats 11 to move. The threaded seat 11 will move along the inside of the movable groove 13. At the same time, the threaded seat 11 will drive the clamping block 12 to move, so that the two clamping blocks 12 move away from each other, thereby facilitating the removal of the battery module 2.

[0030] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
