Description

Technical Field

[0001] This utility model relates to the field of logistics, and in particular to a logistics trolley. Background Technology

[0002] In the logistics field, logistics trolleys are commonly used for transferring goods. Most commercially available trolleys have non-adjustable perimeter railings, requiring relatively high railings to accommodate more cargo, resulting in a large trolley size. Therefore, existing technologies have proposed extendable railings. However, when the extendable section is mounted on a pivot, the distance between the two sides of the trolley must be greater than the length of the extendable section during rotation, limiting its application to wide open areas. Furthermore, the extendable section, being externally attached to the railing, is prone to swaying or scraping during handling. On the other hand, while the extendable section can employ a sliding lifting structure attached to the lower railing, this requires the lifting mechanism to be clamped between the inner and outer sides of the lower railing, increasing the railing thickness, reducing internal loading space, and making lifting difficult due to obstruction by cargo. Therefore, both approaches have shortcomings in practical applications. Utility Model Content

[0003] The purpose of this application is to provide a logistics trolley that addresses the problems existing in the prior art.

[0004] This application provides a logistics trolley, including a platform. A basic fence is fixed to the platform, and the basic fence includes a lower truss fixed to the platform. Multiple supporting vertical beams are fixed at intervals on the lower truss, and an upper truss is fixed to the top of the supporting vertical beams. A lifting fence is inserted into the basic fence, and the lifting fence includes a parallel top rod and a bottom rod. Multiple vertical rods are fixed at intervals between the top rod and the bottom rod. The bottom rod is located between the upper and lower trusses, and a vertically extending through slot is opened on the middle supporting vertical beam to accommodate the bottom rod passing through. A through hole is opened on the upper truss to accommodate the vertical rod passing through. A stop is rotatably connected to the vertical rod, and a receiving groove is opened on the vertical rod corresponding to the stop. The upward rotation angle of the stop is limited by the upper edge of the receiving groove.

[0005] Furthermore, the stop block is installed in the receiving groove via a rotating shaft. A platform is provided on the lower outer side of the stop block. The outer surface of the platform does not extend beyond the surface of the vertical rod. An extended wedge is provided on the stop block on the inner side of the platform, and the starting point of the inclined surface of the wedge is higher than the lower edge of the platform.

[0006] Furthermore, the diameter of the through hole is larger than the diameter of the vertical rod, but smaller than the length of the stop block.

[0007] Furthermore, multiple stops are similarly arranged on the vertical rod, with intervals between the stops.

[0008] Furthermore, the basic fence surrounds the vehicle on three sides, with a lifting fence installed on each side, and the three lifting fences are not connected to each other.

[0009] Furthermore, the entrance of the basic fence is hinged to a fence gate, the other end of which is fixed by a pin; the fence gate has the same structure as the basic fence and is also equipped with a lifting fence.

[0010] The beneficial effects of this utility model are as follows: Considering that the function of the fence is only to restrict goods and does not require high strength, this utility model sets the sliding structure of the lifting fence inside the basic fence. A through groove is opened on the vertical beam of the basic fence to accommodate the lifting fence's sliding motion inside. This does not increase the fence's thickness, is not obstructed by goods, does not reduce the carrying capacity, and the lifting process is smooth and easy to achieve. The lifting fence is fixed by a rotating stop, resulting in a simple structure that is easy to assemble and operate, significantly reducing the cost of the trolley. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1The illustrated logistics trolley includes a platform 1, on which a basic fence is fixed. The basic fence includes a lower truss beam 2 fixed to the platform 1, with multiple supporting vertical beams 3 fixed at intervals on the lower truss beam 2, and an upper truss beam 4 fixed to the top of the supporting vertical beams 3. A lifting fence is inserted into the basic fence, comprising a parallel top rod 5 and a bottom rod 6, with multiple vertical rods 7 fixed at intervals between the top rod 5 and the bottom rod 6. The bottom rod 6 is located between the upper truss beam 4 and the lower truss beam 2, and a vertically extending through slot 8 is formed in the middle supporting vertical beam 3 to accommodate the bottom rod 6. A through hole 9 is formed in the upper truss beam 4 to accommodate the vertical rods 7, so that pulling the top rod 5 upward can move the entire lifting fence upward, raising the height of the fence. Figure 2 As shown. A stop 10 is rotatably connected to the vertical rod 7, as... Figure 3 and Figure 4 As shown, the vertical rod 7 has a receiving groove 11 corresponding to the stop block 10. The upward rotation angle of the stop block 10 is limited by the upper edge of the receiving groove 11, so that the rotation range of the stop block 10 is between 90° and 120°, and it is in a horizontal state. The diameter of the through hole 9 is larger than the diameter of the vertical rod 7 and smaller than the length of the stop block 10. When the stop block 10 is in a horizontal state, it can be locked above the through hole 9 to fix the position of the lifting fence.

[0019] In use, lift the lifting barrier upwards until the stop block 10 is above the upper truss 4. Move the stop block 10 to rotate it upwards to the side. Release the lifting barrier; gravity will cause it to descend, and the stop block 10 will block the barrier at the through hole 9, preventing it from falling and thus fixing its position. To lower the lifting barrier, first lift it so that the entire receiving groove 11 is above the through hole 9. Under its own weight, the stop block 10 will rotate downwards back into the receiving groove 11, allowing the barrier to descend through the through hole 9.

[0020] Specifically, such as Figure 3 and Figure 4 As shown, the stop block 10 is installed in the receiving groove 11 via the rotating shaft 12. A platform 13 is provided on the outer side of the lower end of the stop block 10. The outer surface of the platform 13 does not extend beyond the surface of the vertical rod 7, so that the stop block 10 can pass through the through hole 9 when it is vertical. The stop block 10 on the inner side of the platform 13 is provided with an extended wedge 14, and the starting point of the inclined surface of the wedge 14 is higher than the lower edge of the platform 13, so that there is a distance between the platform 13 and the wedge 14, making it convenient to move the platform 13 by hand and thus drive the stop block 10.

[0021] Each vertical bar 7 includes at least one stop 10 located at the bottom. In order to adjust the lifting height of the lifting fence, multiple stops 10 can be set on the vertical bar 7. There are intervals between the multiple stops 10. The lifting fence can be fixed at different heights by stops 10 of different heights.

[0022] The basic fencing surrounds the vehicle platform 1 on three sides, with a lifting fencing installed on each side. The three lifting fencings are not connected to each other. The height of the fencing on the corresponding side can be selected according to different uses, making the usage more flexible and diverse.

[0023] The entrance to the basic fence is hinged to a fence gate, which, together with the basic fence, surrounds the vehicle platform 1 on all four sides. The other end of the fence gate is secured by a bolt; this is a common design and will not be described in detail here. The fence gate has the same structure as the basic fence and is also equipped with a lifting fence.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
