Description

Technical Field

[0001] The utility model belongs to the technical field of material transport devices, and in particular relates to an adjustable logistics trolley. Background Art

[0002] With the rapid development of the logistics industry, the requirements for the efficiency and flexibility of logistics equipment are increasing. Logistics carts, a common material handling tool in warehouses, factories, and other places, have a direct impact on the efficiency of logistics operations due to their design and performance. Traditional logistics carts often utilize multi-layered storage plates to maximize storage space. However, this fixed structure has significant drawbacks: when materials located on the lower or bottom layers need to be retrieved, the fixed upper storage plates can hinder access and even pose a safety hazard to the operator.

[0003] In order to solve the above problems, an improved solution has been proposed in the prior art, namely, providing a reversible placement plate on the logistics trolley to improve the convenience of storing and accessing materials. It mainly realizes the flipping and positioning of the placement plate through elastic elements such as gas springs. When the placement plate is flipped to the required angle, the gas spring can provide sufficient support force to keep the placement plate stable and motionless, making it convenient for the operator to take and place materials. However, this solution has certain limitations. Especially for the case of carrying heavy objects, the load-bearing capacity of the gas spring often becomes a bottleneck. When the weight of the material loaded on the placement plate exceeds the rated load-bearing capacity of the gas spring, the gas spring may not be able to effectively support it, causing the placement plate to fall suddenly, which not only damages the material, but may also cause harm to the operator, thereby reducing the safety and reliability of the logistics trolley.

DETAILED DESCRIPTION

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0025] As shown in the figure, an adjustable logistics cart includes a support frame 100, a storage plate 200, a first support structure 300, a second support structure 400, a hinge 500, anti-static casters 600 and a handle 700.

[0026] As shown in the figure, an adjustable logistics trolley includes:

[0027] A support frame 100, on which a storage plate 200 is rotatably provided, and the storage plate 200 has a rotational position;

[0028] The support assembly comprises a first support structure 300 and a second support structure 400. The first support structure 300 is rotatably connected to the support frame 100 at one end and to the storage plate 200 at the other end. The second support structure 400 is rotatably connected to the support frame 100 at one end and snap-fitted to the storage plate 200 at the other end. When the storage plate 200 is in the rotated position, the first support structure 300 and the second support structure 400 each apply a supporting force to the storage plate 200. This dual support structure design provides dual support for the rotation of the storage plate 200, enabling flexible adjustment and a high load-bearing capacity for the storage plate 200, effectively improving the convenience of material retrieval and the overall safety of the logistics vehicle.

[0029] As shown in the figure, in this embodiment, the support frame 100 serves as the supporting body of the material trolley, which includes a plurality of cross beams 110 and at least four longitudinal beams 120. The longitudinal beams 120 are arranged vertically in a rectangular shape and are connected to form a rectangular frame through the cross beams 110.

[0030] In this embodiment, the cross beam 110 is arranged in a circular shape along the length direction of the longitudinal beam 120, and divides the support frame 100 into several storage spaces of different heights. There are several storage plates 200, which are arranged one by one in the storage spaces to meet the needs of classified placement of materials of different specifications and categories.

[0031] To facilitate the mobility of the logistics cart, this embodiment also includes four anti-static casters 600, removably attached to the ground-facing ends of the four longitudinal beams 120. This improves the ease of movement and reduces noise and vibration during movement. Furthermore, it protects sensitive goods from electrostatic damage, making it suitable for industrial environments with specific requirements for ESD protection.

[0032] In this embodiment, the longitudinal beam 120 is further provided with a handle 700, which is detachably connected to the longitudinal beam 120 via fasteners. The addition of the handle 700 provides the operator with better controllability, especially when carrying heavy objects, thereby improving the operator's work efficiency and comfort.

[0033] In this embodiment, there are several storage plates 200, which are rotatably arranged on the support frame 100 and have a rotational position and a horizontal position. When the operator needs to take the material on the lower storage plate 200, the upper storage plate 200 can be pushed to turn it from the horizontal position to the rotational position, thereby realizing the flip adjustment of the storage plate 200, thereby facilitating the operator to conveniently take the material.

[0034] In this embodiment, the rotation position can be single or multiple.

[0035] In this embodiment, the storage plate 200 is rotatably connected to the support frame 100 via the hinge 500, ensuring smooth rotation and firm connection of the storage plate 200, extending the service life of the logistics trolley and improving the smoothness of operation.

[0036] Preferably, in this embodiment, each storage board 200 is correspondingly configured with two sets of hinges 500 to ensure the smooth rotation of the storage board 200. One side of the hinge 500 is detachably connected to the side of the storage board 200, and the other side is detachably connected to the beam 110, effectively ensuring the convenience of installation and maintenance.

[0037] To prevent materials from sliding off the storage plate 200, in this embodiment, an extension edge 220 is provided on the storage plate 200. The extension edge 220 is arranged in a U shape and extends vertically away from the storage plate 200. When the storage plate 200 rotates, the extension edge 220 forms abutment with the material, effectively avoiding the risk of materials sliding off the storage plate 200 and hitting the human body, thereby improving the safety of the logistics cart.

[0038] To allow the storage plate 200 to rest freely in any position after rotation, this embodiment includes a support assembly comprising a first support structure 300 and a second support structure 400. The first support structure 300 is rotatably connected to the support frame 100 at one end and to the storage plate 200 at the other end. This structure rotates synchronously with the rotation of the storage plate 200, providing initial support for the storage plate 200 when in the rotated position and allowing the storage plate 200 to be stowed beneath the storage plate 200 when in the horizontal position. The second support structure 400 is rotatably connected to the support frame 100 at one end and engaged with the storage plate 200 at the other end. This structure adjusts its position in real time as the storage plate 200 rotates, providing secondary support for the storage plate 200 when in the rotated position and allowing the storage plate 200 to be stowed to the side of the storage plate 200 when in the horizontal position. Through the cooperation between the first supporting structure 300 and the second supporting structure 400, dual positioning and support of the storage plate 200 are achieved, which effectively improves the load-bearing capacity of the storage plate 200. On the one hand, the load-bearing capacity of the storage plate 200 is expanded so that it can be used to carry heavy objects. On the other hand, the force on the first supporting structure 300 is alleviated, the service life of the first supporting structure 300 is increased, and the safety of the storage plate 200 during the flipping process is improved.

[0039] In this embodiment, the first support structure 300 includes a gas spring 310, one end of which is rotatably connected to the support frame 100, and the other end is rotatably connected to the storage plate 200. When the storage plate 200 is in a rotated position, the gas spring 310 uses its elastic properties to apply a supporting force to the storage plate 200, so that the storage plate 200 can stay in the flipped position.

[0040] Preferably, in this embodiment, one end of the gas spring 310 is rotatably connected to the beam 110 close to the rotation direction of the storage plate 200, and the other end is rotatably connected to the bottom of the storage plate 200. Compared with the side connection method in the prior art, its installation is more convenient and also reduces the space occupied on the side of the storage plate.

[0041] In this embodiment, the first support structure 300 further includes a first connector 320 and a second connector 330. The first connector 320 is detachably mounted on the support frame 100 and rotatably connected to one end of the gas spring 310. The second connector 330 is detachably mounted on the bottom of the storage plate 200 and rotatably connected to the other end of the gas spring 310. The detachable design of the first and second connectors 320 and 330 simplifies the installation and replacement process of the gas spring 310, thereby improving the maintenance efficiency and cost-effectiveness of the logistics vehicle.

[0042] In this embodiment, the second support structure 400 is disposed on the storage plate 200, facing away from the first support structure 300. The second support structure 400 includes a support member 410, one end of which is rotatably connected to the support frame 100 and the other end of which has a groove 411 that engages with the storage plate 200. A protrusion 210 is provided on the side wall of the storage plate 200, which engages with the groove 411. When the storage plate 200 is in the rotated position, the groove 411 engages with the protrusion 210, exerting a supporting force on the storage plate 200. This provides secondary support for the storage plate 200, effectively compensating for the insufficient load-bearing capacity of the gas spring 310, significantly increasing the load-bearing limit of the storage plate 200 when it is flipped, and expanding its application scenarios.

[0043] In this embodiment, the support member 410 is bent into a stepped shape from a rectangular strip, one end of which is rotatably connected to the side of the beam 110 facing away from the storage plate 200, and the groove 411 at the other end is snap-fitted with the protrusion 210. Preferably, the groove 411 is V-shaped. When the protrusion 210 is snapped into the groove 411, the movement of the storage plate 200 can be restricted, and the support member 410 can apply a supporting force to the storage plate 200.

[0044] In this embodiment, the second support structure 400 also includes a fixing member 420, which is detachably connected to the crossbeam 110 of the support frame 100 through the supporting member 410. The supporting member 410 is rotatably connected to the support frame 100 through the fixing member 420, so that the supporting member 410 can support the storage plate 200 when the storage plate 200 is rotated at any angle.

[0045] Preferably, in this embodiment, the fixing member 420 is threadedly connected to the crossbeam 110 and is rotatably connected to the supporting member 410 , so that the supporting member 410 can be rotated to a designated position to engage with the storage plate 200 as needed.

[0046] In order to support the storage plate 200 when it is rotated at different angles, in this embodiment, a plurality of grooves 411 are provided, and are arranged in sequence along the length direction of the support member 410, so that when the support member 410 is rotated at different angles, the grooves 411 can form a snap connection with the protrusion 210, thereby supporting the storage plate 200 at different rotation angles.

[0047] Preferably, in this embodiment, the first support structure 300 and the second support structure 400 are provided in several groups, and each storage board 200 is correspondingly configured with two groups of first support structures 300 and second support structures 400, and the two groups of first support structures 300 and second support structures 400 are symmetrically arranged on both sides of the storage board 200 to ensure stable support for the storage board 200.
