[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides a stacker with adjustable fork spacing, such as Figure 1-4 As shown, the stacker includes a stacker body 1, a door frame 2 is fixedly connected to the front of the stacker body 1, a connecting plate 3 is slidably connected to the outer wall of the door frame 2, a connecting block 4 is fixedly connected to the outer wall of the connecting plate 3, a rotating rod 5 is rotatably connected to the connecting block 4, a motor 6 for driving the rotating rod 5 to rotate is provided on one side of the connecting block 4, two rollers 7 are fixedly connected to the outer wall of the rotating rod 5, a fork 10 is slidably connected to the inside of the connecting plate 3, a connecting rod 9 is fixedly connected to the outer wall of the fork 10, and an arc groove 8 is provided on the outer surface of the roller 7 for the connecting rod 9 to slide.

[0025] The motor 6 is used as a force point for driving the rotating rod 5 to rotate, so that when the motor 6 is running, the output shaft inside it can drive the rotating rod 5 to rotate smoothly, so that the rotating rod 5 can drive the two rollers 7 to rotate smoothly, so that the arc grooves 8 distributed on the surfaces of the two rollers 7 can be in a rotating state to perform arc-shaped extrusion on the two connecting rods 9. When the two connecting rods 9 are respectively subjected to the wave-shaped rotation extrusion of the arc grooves 8, the two connecting rods 9 can respectively drive the forks 10 to move away from or approach each other, so that the two forks 10 can adjust the distance between each other according to the size of the goods, so that the two forks 10 can support and carry the goods according to the size of the goods, so as to expand the carrying range of the goods.

[0026] The bottom of the fork 10 is rotatably connected to an adjusting rod 11, and one end of the adjusting rod 11 away from the fork 10 is movably connected to a fixed block 12. The adjusting rod 11 utilizes its own telescopic characteristics to adjust the length accordingly in coordination with the rise or fall of the fork 10, so that the fork 10 will not be restricted by the fixed block when moving, so that it can move up and down smoothly, and can provide certain support for the fork 10, ensuring that the fork 10 has a good load-bearing capacity, preventing other accidents such as bending or falling off when the fork 10 carries heavy goods, thereby ensuring the safety of the goods during handling.

[0027] The top and bottom of the fork 10 are fixedly connected with a clamping block 13, one side of the connecting block 4 is fixedly connected with a lap plate 14, and the outer surface of the connecting rod 9 is fixedly connected with two limit blocks 15, which are arranged on the lap plate 14. The limit blocks 15 are arranged on the lap plate 14. The limit blocks 15 enable the connecting rod 9 to have a blocking limit point when sliding in the through hole 16, so as to prevent the connecting rod 9 from falling due to the downward angle when it is located in the arc groove 8, thereby ensuring the stability of the connecting rod 9 driving the fork 10 to move.

[0028] A through hole 16 for the connecting rod 9 to be inserted is provided in the lap plate 14, and a slide groove 17 for the fork 10 to slide is provided in the connecting plate 3. The through hole 16 allows the connecting rod 9 to have space to move, so that when the connecting rod 9 is located in the through hole 16 and moves, it will only move in a horizontal state, preventing the connecting rod 9 from accidentally moving in other directions, so that the two forks 10 can move horizontally in a relatively stable manner, so as to achieve the purpose of smoothly completing the adjustment of the distance between the forks 10, so that the two forks 10 can be in the same horizontal position to support and transport the goods, and the slide groove 17 allows the fork 10 to have an embedded moving space, thereby providing the first layer of moving stability for the fork 10. At the same time, the setting of the slide groove 17 allows the block 13 to have space to be inserted into the card groove 18, so as to achieve a more stable movement of the fork 10 and avoid other unexpected situations such as the fork 10 falling immediately when being pressed down by a heavy object.

[0029] A card slot 18 is provided in the connecting plate 3 for the card block 13 to slide, and an embedding slot 19 is provided on the front of the door frame 2 for the fixed block 12 to slide. The card slot 18 provides the card block 13 with an embedding point, so that when the card block 13 is embedded in the card slot 18, the stability of the fork 10 during movement can be greatly improved, and the fork 10 can be prevented from escaping from the slide slot 17 and causing the goods to fall. In addition, the embedding slot 19 provides the fixed block 12 with space to move, so that when the spacing of the forks 10 is adjusted, the forks 10 can drive the adjusting rod 11 and the fixed block 12 to smoothly move synchronously accordingly, avoiding the forks 10 being unable to move due to the limitation of the fixed block 12, thereby achieving the goal that the spacing of the forks 10 can be adjusted while the support effect provided by the adjusting rod 11 also exists.

[0030] Working principle:

[0031] When the spacing between the forks 10 needs to be adjusted, the motor 6 is first started so that the output shaft of the motor 6 drives the rotating rod 5 to rotate, and the rotating rod 5 drives the two rollers 7 to rotate. When the two rollers 7 rotate, the arc grooves 8 in opposite directions can be used to cause the two connecting rods 9 therein to be squeezed by the rotation of the arc grooves 8 so as to move away from each other, so that the two connecting rods 9 can respectively drive the forks 10 to move away from each other, so that the spacing between the two forks 10 can be adjusted according to the size of the goods.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
