Description

Technical Field

[0001] The utility model relates to the field of logistics transfer, in particular to a logistics box transfer device. Background Art

[0002] Logistics originally means "physical distribution" or "goods delivery". It is a part of supply chain activities. It is the process of planning, implementing and controlling the efficient and low-cost flow and storage of goods, service consumption and related information from the place of production to the place of consumption in order to meet customer needs. The transshipment of logistics requires the use of logistics transshipment equipment.

[0003] A search of the patent document with publication number CN221938237U reveals "a logistics transport transfer vehicle. This device utilizes an elastic band disposed on the top of the box body to protect the vehicle while transferring goods. The shaking during transfer can cause the stacked goods in the box body to fall or collapse. Before starting, the first and second rotating blocks are twisted to pull the elastic band to an appropriate length based on the height and number of the goods. During subsequent stacking, the horizontal and vertical elastic bands form a cross to secure the goods."

[0004] Although the above-mentioned device can place the transferred logistics box through the box structure, the side panels of the box have a certain height. When placing the logistics box into the box, the logistics box needs to be lifted to a certain height before it can be placed into the box, which is time-consuming and labor-intensive. Moreover, if the weight of the goods in the logistics box is heavy, multiple people are needed to lift the logistics box into the box. Utility Model Content

[0005] The purpose of the present utility model is to provide a logistics box transfer device in order to solve the above problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-8 As shown, a logistics box transfer device includes a base plate 1, a moving mechanism is installed at the bottom of the base plate 1, and also includes a supporting mechanism.

[0030] The moving mechanism includes four universal wheels 11, which are respectively installed at the four corners of the lower end of the base plate 1. The universal wheels 11 have a self-locking structure. A fixing frame 12 is fixed to the bottom of one end of the base plate 1. The bottom of the fixing frame 12 is higher than the bottom of the universal wheel 11. One end of the fixing frame 12 is rotatably connected to the pushing frame 13. The front and rear ends of the fixing frame 12 are slidably connected to the top frame 14. One end of the top frame 14 is inserted into the pushing frame 13, and a spring 15 is provided on the periphery of the two rods of the top frame 14. One end of the spring 15 is fixed to the fixing frame 12, and the other end is fixed to the top frame 14. The arrangement of the universal wheels 11 can make the device move as needed, and the arrangement of the pushing frame 13 can enable the worker to push the device to move. By pulling the top frame 14, it can be separated from the pushing frame 13, so that the pushing frame 13 can be flipped down.

[0031] The supporting mechanism includes two short bottom bars 2, both of which are fixed to the upper end of the bottom plate 1, and the upper ends of the two short bottom bars 2 are rotatably connected to the short plate 21. Two long bottom bars 22 are arranged between the two short bottom bars 2, and the two long bottom bars 22 are fixed to the bottom plate 1, and the upper ends of the two long bottom bars 22 are rotatably connected to the long plate 23. Both ends of the two long plates 23 are provided with a stabilizing component for fixing to the short plate 21, and the stabilizing component includes multiple side ears 24, both ends of the two long plates 23 are fixed with side ears 24, and the middle of the side ears 24 is provided with a pin 25, the outer wall of the pin 25 is provided with a rubber layer, and the bottom of the pin 25 is provided with a short cylindrical structure with a diameter larger than itself, the front and rear ends of the short plate 21 are provided with grooves corresponding to the side ears 24, and the rubber layer on the outer wall of the pin 25 is fitted with the inner wall of the groove opened in the short plate 21, and the pin 25 passes through the side ears 24 and the grooves opened in the short plate 21 corresponding to the side ears 24.

[0032] A plurality of fixing rods 26 are fixed to the inner walls of the two short plates 21 and the two long plates 23. The outer ring of each fixing rod 26 is rotatably connected to a rotating tube 27. The outer rings of the two short plates 21 and the two long plates 23 are provided with a lifting frame 211. The distance between the top of the short bottom bar 2 and the long bottom bar 22 and the bottom plate 1 is fifteen centimeters. The thickness of the lifting frame 211 is less than the height of the short bottom bar 2 and the long bottom bar 22. A driving structure is installed at the lower end of the lifting frame 211. The driving structure includes a screw 28. The screw 28 is threadedly connected to the front side of one end of the lifting frame 211. A motor 29 is installed at the input end of the screw 28. The screw 28 is rotatably connected to the bottom plate 1. The rear side of the other end of the lifting frame 211 is slidably connected to the guide rod 210, and the guide rod 210 is fixed to the bottom plate 1.

[0033] The outer walls of the two short plates 21 and the two long plates 23 are slidably connected to the sliders 212, and the positions of the lifting frame 211 corresponding to the four sliders 212 are rotatably connected to the rotating blocks 213. The rotating blocks 213 are rotatably connected to the lifting frame 211 through the circular shaft structures at both ends, and each rotating block 213 is hinged to the corresponding slider 212; through the threaded connection between the lifting frame 211 and the screw 28 and the sliding connection between the lifting frame 211 and the guide rod 210, when the motor 29 drives the screw 28 to rotate, the lifting frame 211 can be raised and lowered.

[0034] Of course, the present application may also not set up a stabilizing component, and only use the lifting frame to close and limit the long board 23 and the short board 21. However, it is better and more stable to choose to set up a stabilizing component.

[0035] Working principle: When a logistics box needs to be placed in the device or removed from the device, the four latches 25 are first pulled up to separate them from the side ears 24. The rubber layer on the outer wall of the latches 25 fits into the holes of the short plate 21, and the latches 25 are pulled up to prevent them from falling under their own weight. Then, the top frame 14 is pulled to separate it from the push frame 13. The push frame 13 is rotated and connected to the fixed frame 12, so that the push frame 13 can be flipped down.

[0036] After the preparation work is completed, through the threaded connection between the lifting frame 211 and the screw 28 and the sliding connection between the lifting frame 211 and the guide rod 210, when the motor 29 drives the screw 28 to rotate, the lifting frame 211 can be lowered. When the lifting frame 211 descends, the hinged connection between the rotating block 213 and the slider 212 can make the rotating block 213 drive the slider 212 to descend accordingly. When the slider 212 drops to the bottom of the long board 23 and the short board 21 slots, the lifting frame 211 continues to descend, and the lifting frame 211 can be lowered to the short bottom bar 2 and the long bottom bar 22. At the same time, the lifting frame 211 will generate a pulling force on the rotating block 213 and the slider 212. Through the rotation connection between the rotating block 213 and the lifting frame 211 and the continuous decline of the lifting frame 211, the rotating block 213 can be driven to rotate. The block 213 rotates counterclockwise about ninety degrees, and at the same time, the rotation and descent of the rotating block 213 can drive the short plate 21 and the long plate 23 to flip outward through the slider 212, so that the short plate 21 and the long plate 23 form a plane. In this way, workers only need to lift the logistics box slightly to make it located on the short plate 21 and the long plate 23, and then push the logistics box to the middle of the device. At the same time, the rotating tube 27 is connected to the fixed rod 26 through rotation, which can reduce the friction of the logistics box when pushing it onto the device, making the operation more labor-saving. After the logistics box is taken out or placed, the motor 29 drives in reverse to make the lifting frame 211 rise and reset, so that the two short plates 21 and the two long plates 23 flip up to form a rectangular box structure again.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
