[0002] ‌The main function of a push cart is to help people easily carry items and reduce the burden and pressure during cargo handling. The goods are placed on the push cart and transported to a designated location. Most of the existing push carts adopt a flat support method, and the goods are directly placed naked on its surface, which not only has poor stability but also low safety. Especially when transporting some high-value medical goods, a box-type push cart is mostly required. However, the internal space specifications of the current box-type push carts are fixed and cannot be quickly adjusted according to the required goods, resulting in limited applicability.‌ Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the existing flat push carts have poor stability and low safety, while the internal space specifications of the box-type push carts are fixed and cannot be quickly adjusted according to the required goods, resulting in limited applicability.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a modular push cart with a multi-directional conveying mechanism, including a main frame. A bottom support wheel for convenient movement is installed on the lower surface of the main frame. A main frame is fixedly assembled at the upper end of the main frame. An external housing is fixedly assembled on the outer side surface of the main frame. A plurality of modular storage boxes arranged in parallel are installed inside the main frame. A top-mounted material conveying mechanism is installed at the upper end of the modular storage box, and a bottom-mounted discharging mechanism is arranged at the lower end of the modular storage box. A longitudinal material guiding and conveying mechanism is movably assembled on the external housing.

[0005] The external housing includes a fixed housing fixed on the back and right side of the main frame, a sliding and folding housing movably installed at the front end of the main frame, and a sliding flexible housing movably installed on the left side of the main frame.

[0006] A detachable internal support frame for supporting the modular storage box is assembled inside the main frame.

[0007] The lower surface of the modular storage box has a downward convex bottom limit frame. An elastic positioning power transmission terminal matched with the detachable internal support frame is elastically assembled on the side wall of the bottom limit frame. A positioning power transmission slot matched with the elastic positioning power transmission terminal is opened on the side wall of the detachable internal support frame.

[0008] The top-mounted material conveying mechanism includes an installation frame fixed at the upper end of the modular storage box and an electric control material conveying belt connected to the upper end inside the installation frame.

[0009] A bottom discharge opening is provided on the inner side of the bottom limit frame on the lower surface of the modular storage bin.

[0010] The bottom-mounted discharge mechanism includes a magnetically controlled clamping module installed on the inner side surface of the modular storage bin and a magnetically controlled flip-up opening and closing plate movably installed inside the bottom discharge opening.

[0011] The longitudinal material guiding and conveying mechanism includes a lateral lifting frame fixed on the outer side surface of the sliding flexible housing, a bottom side adjusting seat movably installed at the lower end of the opening on the outer side surface of the lateral lifting frame, and a flip-up support cover plate movably installed on the bottom side adjusting seat.

[0023] Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A modular push cart with a multi-directional conveying mechanism as shown in the figures includes a main frame 1, bottom support wheels 2 for convenient movement are installed on the lower surface of the main frame 1, a main frame 3 is fixedly assembled at the upper end of the main frame 1, an external housing 4 is fixedly assembled on the outer side surface of the main frame 3, a plurality of modular storage bins 5 arranged in parallel are installed inside the main frame 1, a top-mounted feeding mechanism 6 is installed at the upper end of the modular storage bin 5, a bottom-mounted discharging mechanism 7 is arranged at the lower end of the modular storage bin 5, and a longitudinal material guiding and conveying mechanism 8 is movably assembled on the external housing 4.

[0024] Adjustment principle: A control panel with adjustable angle is installed at the upper end of the main frame 3. Through the control panel, the overhead feeding mechanism 6, the bottom discharging mechanism 7, and the longitudinal material guiding and conveying mechanism 8 can be controlled respectively. The control program and this equipment adopt existing technologies. By means of a pre-set program, the storage positions of specified goods can be recorded, and the goods information inside the modular storage bin 5 can be displayed through the control panel. Then, the goods information is scanned through the camera and the QR code scanner on the control panel to quickly search out the positions of the goods. Then, the goods are placed on the longitudinal material guiding and conveying mechanism 8, and the height is adjusted by using the longitudinal material guiding and conveying mechanism 8. Then, the goods are imported to the lower end of the specified modular storage bin 5 through the overhead feeding mechanism 6, and the imported goods are lifted into the modular storage bin 5 by using the bottom discharging mechanism 7 to complete the feeding. When discharging, the goods inside the modular storage bin 5 are controlled to be imported into the overhead feeding mechanism 6 through the bottom discharging mechanism 7 and lifted to the highest position from the longitudinal material guiding and conveying mechanism 8.

[0025] To cooperate with external assembly sealing, the external housing 4 includes a fixed housing 41 fixed to the back and right side of the main frame 1, a sliding and folding housing 42 movably installed at the front end of the main frame 1, and a sliding flexible housing 43 movably installed at the left side of the main frame 1.

[0026] To facilitate internal installation, a detachable internal support frame 9 for supporting the modular storage bin 5 is assembled inside the main frame 1.

[0027] The detachable internal support frame 9 is fixed to the inner wall of the fixed housing 41 on the back of the main frame 1 by bolts and can be adjusted in position according to the modular storage bins 5 of different specifications and sizes, thus facilitating assembly.

[0028] To cooperate with bottom limit assembly and positioning power supply, the lower surface of the modular storage bin 5 has a downward protruding bottom limit frame 51, and elastic positioning power transmission terminals 52 that cooperate with the detachable internal support frame 9 are elastically assembled on the side wall of the bottom limit frame 51. Positioning power transmission slots 53 that cooperate with the elastic positioning power transmission terminals 52 are provided on the side wall of the detachable internal support frame 9.

[0029] The bottom limit frame 51 is fixed to the detachable internal support frame 9 by inserting the elastic positioning power transmission terminals 52 on the outside into the positioning power transmission slots 53, thereby improving stability.

[0030] To cooperate with top feeding, the overhead feeding mechanism 6 includes an installation frame 61 fixed to the upper end of the modular storage bin 5 and an electric control feeding belt 62 connected to the upper end inside the installation frame 61.

[0031] To cooperate with bottom discharging, a bottom discharging opening 54 is provided on the lower surface of the modular storage bin 5 inside the bottom limit frame 51.

[0032] To cooperate with blanking, the bottom-mounted unloading mechanism 7 includes a magnetically controlled clamping module 71 installed on the inner side of the modular storage bin 5 and a magnetically controlled flip-up opening and closing plate 72 movably installed inside the bottom unloading port 54.

[0033] The magnetically controlled clamping module 71 includes an embedded upper electromagnet installed on the inner side of the modular storage bin 5, an upper iron spring installed on the side wall of the embedded upper electromagnet, and a lateral extrusion block installed at the telescopic end of the upper iron spring; The magnetically controlled flip-up opening and closing plate 72 includes a flip support plate movably installed on the inner wall of the bottom unloading port 54, a side-mounted lower electromagnet fixed on the inner wall of the bottom limit frame 51, and a compression elastic sheet installed between the flip support plate and the side-mounted lower electromagnet.

[0034] By opening and closing the side-mounted lower electromagnet to control the contraction and elastic reset of the compression elastic sheet, the angle of the flip support plate is changed.

[0035] The blanking method is to first elastically clamp the goods at the lower end by the magnetically controlled clamping module 71, then use the downward flipping of the magnetically controlled flip-up opening and closing plate 72 to discharge the lowermost goods downward onto the top-mounted feeding mechanism 6, then drive the goods to be conveyed and guided to the magnetically controlled flip-up opening and closing plate 72 on one side by the top-mounted feeding mechanism 6, then the magnetically controlled flip-up opening and closing plate 72 on the other side flips upward and resets, then the top-mounted feeding mechanism 6 drives the goods to be separated in reverse translation from the magnetically controlled flip-up opening and closing plate 72 on one side, and then elastically flips and resets the magnetically controlled flip-up opening and closing plate 72 at this position.

[0036] The magnetically controlled flip-up opening and closing plate 72 and the top-mounted feeding mechanism 6 adopt a staggered layout for convenient flipping.

[0037] To cooperate with vertical guiding and flipping opening and closing control, the longitudinal guiding and conveying mechanism 8 includes a lateral lifting frame 81 fixed on the outer side of the sliding flexible housing 43, a bottom-side adjusting seat 82 movably installed at the lower end of the opening on the outer side of the lateral lifting frame 81, and a flip support cover plate 83 movably installed on the bottom-side adjusting seat 82.

[0038] A horizontal adjusting motor for controlling the flipping adjustment of the flip support cover plate 83 is installed inside the bottom-side adjusting seat 82, and the horizontal adjusting motor adjusts the adjustment angle of the flip support cover plate 83 by rotation.

[0039] To cooperate with longitudinal guiding, the sliding flexible housing 43 includes a top-mounted embedded electric control rolling curtain 431 fixed on the upper end of the left inner wall of the main frame 3, a bottom-mounted embedded electric control rolling curtain 432 fixed on the lower end of the left inner wall of the main frame 3, an upper flexible rolling cloth 433, and a lower flexible rolling cloth 434.

[0040] The upper flexible rolling curtain 433 is wound inside the top-mounted embedded electric control rolling curtain 431, and the upper flexible rolling curtain 433 is driven by the top-mounted embedded electric control rolling curtain 431 to rise and fall. The lower flexible rolling curtain 434 is wound inside the bottom-mounted embedded electric control rolling curtain 432, and the lower flexible rolling curtain 434 is driven by the bottom-mounted embedded electric control rolling curtain 432 to rise and fall. The synchronous rise and fall of the upper flexible rolling curtain 433 and the lower flexible rolling curtain 434 are used to control the rise and fall of the longitudinal material guiding and conveying mechanism 8. By adjusting the height of the longitudinal material guiding and conveying mechanism 8, the longitudinal material guiding and conveying mechanism 8 is raised to the height of goods discharging, so that the discharging is introduced onto the longitudinal material guiding and conveying mechanism 8, and then lifted to the upper end by the longitudinal material guiding and conveying mechanism 8, which is convenient for people to take; at the same time, the longitudinal material guiding and conveying mechanism 8 can also be used for loading operations of goods.

[0041] During loading, only the goods to be loaded need to be placed on the longitudinal material guiding and conveying mechanism 8, and then the longitudinal material guiding and conveying mechanism 8 is controlled to rise and fall to a specified height. Then, the goods are flipped and extruded onto the top-mounted material conveying mechanism 6 by flipping the supporting cover plate 83, and are translated to the specified loading position by the top-mounted material conveying mechanism 6. After the magnetically controlled flipping opening and closing plate 72 at one end is flipped downward for inclined material guiding, the magnetically controlled flipping opening and closing plate 72 on the other side is then flipped downward, and then the magnetically controlled flipping opening and closing plates on both sides are flipped upward simultaneously to achieve the purpose of bottom-up flipping loading.

[0042] To cooperate with folding and flipping adjustment, the sliding folding cover 42 includes a lower flipping closing plate 421 movably installed inside the front opening of the main frame 3, an upper flipping closing plate 422 movably installed at the upper end of the lower flipping closing plate 421, and a limit locking body 423 fixed to the upper end of the outer side surface of the lower flipping closing plate 421.

[0043] The lower ends of both sides of the lower flipping closing plate 421 are movably connected to the inner wall of the front opening of the main frame 3 by a movable shaft, and the upper ends of both sides of the upper flipping closing plate 422 are slidably adjusted to the inner wall of the front opening of the main frame 3 by a limit shaft. When people operate the lower flipping closing plate 421 and the upper flipping closing plate 422 to flip upward, when the lower flipping closing plate 421 and the upper flipping closing plate 422 close the front opening of the main frame 3, the limit locking body 423 is used to limit the angles of the lower flipping closing plate 421 and the upper flipping closing plate 422, and at the same time, the limit locking body 423 can improve safety. The limit locking body 423 is a very common telescopic lock on the market.

[0044] Longitudinal side rails are symmetrically fixed on the inner wall of the left opening of the main frame 3 and the inner wall of the front opening of the main frame 3, which can improve the guiding performance of the side lifting frame 81, the lower flipping closing plate 421 and the upper flipping closing plate 422.
