Description

Technical Field

[0001] This utility model relates to the field of logistics turnover and transportation vehicle technology, and in particular to a folding logistics turnover and transportation vehicle. Background Technology

[0002] A logistics turnover transport vehicle is a unit-type mobile container equipment equipped with four casters for transporting and storing materials. It typically consists of a frame with wheels, and the frame is a box structure with an open top.

[0003] For example, a folding logistics turnover transport vehicle, with publication number CN208813258U, has positioning plates at the bottom of the side rods of the front and rear frames. The positioning plates have upper protrusions and strip-shaped lower hems. The positioning plates have positioning frames on the outside. The upper end of the positioning frame has a horizontal block extending upwards to the upper protrusion. A rotating shaft passes through the positioning frame and is connected to the near bottom end of the side rod, which then connects the positioning plate to the annular groove in the middle. The bottom plate has a limiting plate corresponding to the positioning plate. The limiting plate is obliquely set and has a strip-shaped groove through which the outer corner of the lower hem of the positioning plate passes. The inner edge of the bottom side of the strip-shaped groove abuts against the bottom end of the lower hem. The positioning frame and the limiting plate act on the positioning plates to restrict the outward rotation of the front and rear frames. During transportation, the front and rear frames can be vertically fixed to protect the materials. When stationary, a braking system prevents slippage and tipping. When stored, the front and rear frames are folded to save space.

[0004] However, in actual operation, the dimensions of the front and rear frames are fixed. Therefore, when the vehicle is used in a vertical position, the overall height of the transport vehicle is fixed. As a result, when transporting small or oversized items, the height of the vehicle may not match the height of the items, which may lead to the vehicle being used for a small purpose or instability during transportation due to size mismatch.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figure 1-4 As shown, a folding logistics turnover transport vehicle includes a movable base plate 1. Several anti-slip strips 2 are installed on the upper surface of the movable base plate 1 to prevent the transported materials from slipping. Folding components are installed on both short sides of the upper surface of the movable base plate 1. Each folding component includes two folding strips 5 distributed longitudinally. Connecting plates 11 are hinged to both ends of the bottom edge of the upper folding strip 5, and hinge plates 10 are hinged to both ends of the upper surface of the lower folding strip 5. The hinge plates 10 and connecting plates 11 on the same side of the movable base plate 1 are hinged together at their swing edges. A diagonal brace 12 is also hinged to the swing edge of the hinge plate 10. A slider 13, which is embedded in the upper surface of the lower folding strip 5, is hinged to the swing edge of the diagonal brace 12. Inserts 8 are inserted into the side of the folding strip 5. The inserts 8 are U-shaped, and elastic ropes 9 are provided between both ends of the insert 8 and the side of the folding strip 5. The ends of the insert 8 are used to pass through the folding strip 5 and the slider 13. Figure 2As shown, the elastic rope 9 is designed so that the plug 8 fits against the side of the folding strip 5 under normal conditions. The plug 8 and the slider 13 are connected through the plug to ensure that the slider 13 is fixed in position within the folding strip 5. Therefore, the inclined support plate 12, the hinge plate 10, and the bottom edge of the hinge plate 10 and the inclined support plate 12 form a complete triangle. The triangle has stability, so the hinge plate 10 can be kept vertical, thus ensuring that the connecting plate 11 connected to the hinge plate 10 is fixed in position. Therefore, the two folding strips 5 can be completely separated. Conversely, when folding and storing, simply pull the plug 8 to release the plug 8 from the slider 13, so that the slider 13 can slide within the folding strip 5. This releases the stability of the hinge plate 10, so the hinge plate 10 and the connecting plate 11 can move, and the two folding strips 5 can be folded and overlapped. In addition, the number of folding components can be selected according to the stacking height of the items to ensure that the height of the transport vehicle matches the size of the items, ensuring comfort during use.

[0024] Furthermore: Both sides of the long sides of the folding strip 5 are fixedly connected to the bottom edge with rails 6, and both sides of the long sides of the folding strip 5 are provided with slots 7 near the top edge. In two adjacent folding strips 5 of adjacent folding assemblies on the same side of the movable base plate 1, the rail 6 on one folding strip 5 is inserted into the slot 7 on the other folding strip 5. Mounting holes 17 are provided on both sides of the upper surface of the folding strip 5. Two adjacent folding strips 5 of adjacent folding assemblies on the same side of the movable base plate 1 are connected by bolts passing through the mounting holes 17. The folding strip 5 is also connected to the upper surface of the movable base plate 1 by bolts passing through the mounting holes 17. By using the rails 6 and slots 7, the vertical position of adjacent folding assemblies can be fixed. Using bolts passing through the mounting holes 17, the relative position in the front-to-back direction can be fixed. Additionally, using bolts passing through the mounting holes 17 and the movable base plate 1, the relative position of several stacked folding assemblies to the movable base plate 1 can be fixed.

[0025] Furthermore: Connectors 15 are installed on one long side of the movable base plate 1, at the end of the folding strip 5. Rear stop bars 3 are hinged within the connector 15. The two rear stop bars 3, at the same height, have columnar faces and are fitted with threaded sleeves 14. Pins 16 are inserted between the connector 15 and the rear stop bars 3. The opposing faces of the two rear stop bars 3 at the same height are studded and threadedly connected to the threaded sleeves 14. Therefore, after fixing the relative positions of the connector 15 and the folding strip 5 with bolts, rotating the rear stop bars 3 achieves the same position... With the ends of the two rear stop bars 3 aligned, one end of the threaded sleeve 14 can be moved from one rear stop bar 3 to the threaded part of the other rear stop bar 3 by rotating the threaded sleeve 14. This ensures that the central axes of the opposite end faces of the two rear stop bars 3 coincide. The connector 15 is fixed to the rear stop bar 3 by installing a pin 16. The two rear stop bars 3 of the same height after assembly can fix the relative position of one end of the two folding components of the same height. In addition, the rear stop bars 3 can further prevent items from slipping.

[0026] Furthermore, a lifting handle 4 is installed on the upper surface of the top folding strip 5, which makes it easy for personnel to lift and unfold the folding assembly, and the lifting handle 4 also makes it easy for personnel to push the movable base plate 1 to move.

[0027] Working principle: During use, pull the inserts 8 one by one from top to bottom, then lift the handle 4 upwards to unfold the folding assembly in a top-to-bottom sequence. Utilizing the hinges of the connecting plate 11, hinge plate 10, and diagonal brace 12, pull the slider 13 to the upper end of the folding strip 5. Then release the inserts 8, and under the elastic contraction of the elastic rope 9, the inserts 8 return to their original position, passing through the slider 13 at the end of the folding strip 5. This fixes the slider 13 at the end of the folding strip 5, keeping the folding assembly in the unfolded and raised state. Then, rotate the connector 1 at the end of the folding strip 5 horizontally. The rear stop bar 3 inside 5 aligns the ends of the two rear stop bars 3 at the same height. By rotating the threaded sleeve 14, one end of the threaded sleeve 14 can be moved from one rear stop bar 3 to the threaded part of the other rear stop bar 3, thus ensuring that the central axis of the opposite end face of the two rear stop bars 3 coincides. The connector 15 is fixed to the rear stop bar 3 by installing the pin 16. The two rear stop bars 3 at the same height after assembly can fix the relative position of one end of the two folding components at the same height. In addition, the rear stop bars 3 can also further prevent items from slipping.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
