Description

Technical Field

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

[0002] A pallet truck, also known as a hand-pushed pallet truck or flatbed truck, is a short-distance transport tool widely used in warehouses, logistics facilities, factories, supermarkets, and other similar locations. Its traditional structure typically includes a carrying platform, a push-pull handle, and wheels at the bottom.

[0003] However, most existing pallet trucks have relatively simple functions and fixed structures. This leads to several limitations in their use: First, the fixed structure makes it difficult to adapt to goods of varying sizes. When moving large items, the platform area may be insufficient, causing the goods to be unstable and prone to slipping. When moving small or loose items, they are cumbersome and inefficient. Second, in some special handling scenarios, such as when goods need to be scooped directly from the ground or tilted at a certain angle, traditional pallet trucks are often inadequate, requiring the use of other tools or manpower, which not only increases labor intensity but also reduces work efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a multi-functional trolley that can flexibly change its form according to actual transportation needs, so as to solve the problems of poor adaptability and single function in the existing technology.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A multi-functional trolley includes a main frame and a push-pull mechanism. The main frame is movably connected to the push-pull mechanism. Wheels are respectively provided at the bottom of the main frame and the bottom of the push-pull mechanism. The push-pull mechanism includes a support frame and two connecting components symmetrically arranged on both sides of the support frame. The connecting components include a sliding sleeve and a fixing bolt. The sliding sleeve slides with the support frame, and the fixing bolt passes through the sliding sleeve and the support frame and fixes them to one end of the main frame. The main frame can be operated and fixed in several different forms, including: a first form in which the main frame coincides with the push-pull mechanism and the wheels at the bottom of the main frame are in contact with the ground; a second form in which the main frame is horizontal to the ground and forms a 90° angle with the push-pull mechanism; and a third form in which the main frame rotates relative to the push-pull mechanism and stops at an intermediate angle between the first and second forms, forming an inclined bearing surface for leaning against and transporting goods.

[0007] This multi-functional cargo cart achieves a comprehensive advantage in terms of functional integration, operational flexibility, and scenario adaptability through its modular design and multi-mode switching mechanism. Specifically, the main frame can be operated and fixed in three different modes to cover various usage scenarios. In the first mode, the main frame and push-pull mechanism fold and overlap, resulting in a compact structure suitable for short-distance rapid transfer of light goods or movement in confined spaces. In the second mode, the main frame is horizontal to the ground, enabling the transport of large quantities of goods at once, meeting the needs of cargo handling. In the third mode, the inclined design at the middle angle provides an inclined, leaning load-bearing surface, suitable for the stable transport of irregular goods, reducing the risk of cargo slippage, and facilitating push-pull operation during manual loading and unloading. Furthermore, in this design, the adjustment of each mode relies on the cooperation of sliding sleeves and fixing bolts. Users can directly slide to adjust the angle of the main frame without additional tools, and the mode switching time is short, which helps to improve operational efficiency.

[0008] Furthermore, a fixing rod is located near the bottom of the support frame, with both ends of the fixing rod fixedly connected to the sides of the support frame. A slot is located in the middle of the bottom of the main frame, which engages with the fixing rod in the first configuration. In the first configuration, the main frame and the push-pull mechanism achieve double locking through a combination of fixing bolts and the engaging connection. The bolts are used to fix the angle, while the slot and fixing rod physically engage. This avoids the possibility of loosening due to vibration and bumps when relying solely on bolt connections, thus ensuring that the overall structure does not shift relative to each other after folding. Simultaneously, when the user folds the main frame to the overlapping position, the slot engages with the fixing rod, creating a pre-locking effect. Afterward, only tightening the fixing bolts is needed to complete the final locking, saving time compared to simply using bolts for fixing, as it eliminates the need for manually aligning multiple bolt holes.

[0009] Furthermore, it also includes a support component. One end of the support component is fixedly connected to the fixing rod, and a groove is provided at the bottom of the main frame. The other end of the support component slides into the groove. In the third configuration, the support component slides within the groove, forming a triangular support structure together with the main frame and the support frame. This enhances the stability of the structure and avoids the loosening problem that may occur when the main frame and the support frame are only fixed by connecting components in the third configuration, thereby improving the overall load-bearing capacity.

[0010] Furthermore, the main frame includes a support frame, a support baffle, and a U-shaped handle. One end of the support frame is connected to a support frame, and the support baffle is vertically positioned at the end of the support frame away from the support frame. The U-shaped handle is rotatably connected to the support frame. In the first and third configurations, the support baffle serves as a support structure for the bottom of the transported goods; in the second configuration, it effectively prevents goods from slipping due to inertia during pushing and pulling. The U-shaped handle, in the second configuration, can work in conjunction with the pushing and pulling mechanism to facilitate the transport of heavier goods by two people, achieving a time-saving and labor-saving effect. Simultaneously, the U-shaped handle can also serve as an extension of the support baffle, enabling it to support and transport larger volumes of goods when opened in the second configuration.

[0011] Furthermore, symmetrical push-pull handlebars are provided at the rear of the main frame. The height of the symmetrical handlebars is typically designed within the range of an adult's waist to chest, allowing users to push and pull in various postures, such as upright or slightly bent over. Additionally, in the second configuration, the design of the push-pull handlebars and U-shaped pull handles allows two people to push and pull separately, making it easier to move heavy objects.

[0012] Furthermore, symmetrical fixing parts are provided on both sides of the support frame near one end of the support frame. Each fixing part has a fixing groove, and the sliding sleeve engages in the fixing groove to secure the support frame. During use, regardless of its orientation, the sliding sleeve always remains engaged with the fixing groove, thereby enhancing the stability of the structure.

[0013] In summary, this multi-functional trolley can flexibly change its form according to actual transportation needs, solving the problems of poor adaptability and limited functionality in existing technologies. Attached Figure Description

They are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] like Figures 1 to 3 As shown, a multi-functional trolley includes a main frame 1 and a push-pull mechanism 2. The main frame 1 and the push-pull mechanism 2 are movably connected. Wheels 3 are respectively provided at the bottom of the main frame 1 and the bottom of the push-pull mechanism 2. The push-pull mechanism 2 includes a support frame 21 and two connecting components 22 symmetrically arranged on both sides of the support frame 21. The connecting components 22 include a sliding sleeve 221 and a fixing bolt 222. The sliding sleeve 221 is slidably engaged with the support frame 21. The fixing bolt 222 passes through the sliding sleeve 221 and the support frame 21 and fixes them to one end of the main frame 1. The main frame 1 can be operated and fixed in a variety of different forms, including: a first form in which the main frame 1 overlaps with the push-pull mechanism 2 and the bottom wheels 3 of the main frame 1 are in contact with the ground; a second form in which the main frame 1 is horizontal to the ground and the main frame 1 is at a 90° angle with the push-pull mechanism 2; and a third form in which the main frame 1 rotates relative to the push-pull mechanism 2 and stops at an intermediate angle between the first and second forms, forming an inclined bearing surface for leaning against and transporting goods.

[0022] This multi-functional trolley achieves a comprehensive advantage in terms of functional integration, operational flexibility, and scenario adaptability through modular design and a multi-mode switching mechanism. Specifically, the main frame 1 can be operated and fixed in three different modes to cover different usage scenarios. In the first mode, the main frame 1 and the push-pull mechanism 2 are folded and overlapped, resulting in a compact structure suitable for short-distance rapid transfer of light goods or movement in confined spaces. In the second mode, the main frame 1 is horizontal to the ground, enabling the transport of large quantities of goods at once, meeting the needs of cargo handling. In the third mode, the inclined design at the middle angle provides an inclined, leaning bearing surface, suitable for the stable transport of irregular goods, reducing the risk of cargo slippage, and facilitating push-pull operation during manual loading and unloading. Furthermore, in this design, the adjustment of each mode relies on the cooperation of the sliding sleeve 221 and the fixing bolt 222. Users can directly slide to adjust the angle of the main frame 1 manually, completing the fixing without additional tools. The mode switching time is short, which helps to improve operational efficiency.

[0023] Furthermore, a fixing rod 211 is provided near the bottom of the support frame 21. The two ends of the fixing rod 211 are fixedly connected to the sides of the support frame 21. A slot 11 is provided at the middle of the bottom of the main frame 1. In the first configuration, the slot 11 engages with the fixing rod 211. In the first configuration, the main frame 1 and the push-pull mechanism 2 achieve double locking through the fixing bolt 222 and the engaging connection. The bolt is used to fix the angle, while the slot 11 and the fixing rod 211 achieve physical engagement. This avoids the possibility of loosening of the threads due to vibration and bumps when relying solely on bolt connections, thus ensuring that the overall structure does not undergo relative displacement after folding. At the same time, when the user folds the main frame 1 to the overlapping position, the slot 11 will fit into the fixing rod 211, forming a pre-fixed effect. After that, only tightening the fixing bolt 222 is needed to complete the final locking, saving the time of manually aligning multiple bolt holes compared to simply using bolt fixing.

[0024] Furthermore, it also includes a support member 4, one end of which is fixedly connected to the fixing rod 211. A groove 12 is provided at the bottom of the main frame 1, and the other end of the support member 4 slides in the groove 12. In the third configuration, the support member 4 slides within the groove 12, forming a triangular support structure together with the main frame 1 and the support frame 21. This enhances the stability of the structure and avoids the loosening problem that may occur when the main frame 1 and the support frame 21 are only fixed by the connecting component 22 in the third configuration, thereby improving the overall load-bearing capacity.

[0025] Furthermore, the main frame 1 includes a support frame 13, a support baffle 14, and a U-shaped handle 15. One end of the support frame 13 is connected to the support frame 21. The support baffle 14 is vertically disposed at the end of the support frame 13 away from the support frame 21. The U-shaped handle 15 is rotatably connected to the support frame 13. In the first and third configurations, the support baffle 14 can serve as a support structure for the bottom of the transported goods. In the second configuration, it can effectively prevent the goods from slipping due to inertia during pushing and pulling. The design of the U-shaped handle 15 allows it to cooperate with the pushing and pulling mechanism 2 in the second configuration, facilitating the transport of heavier goods by two people, achieving a time-saving and labor-saving effect. At the same time, the U-shaped handle 15 can also serve as an extension of the support baffle 14, and when opened in the second configuration, it can support and transport larger goods.

[0026] Furthermore, the rear of the main frame 1 is symmetrically equipped with push-pull handles 5. The height of the symmetrical handles is typically designed within the range of an adult's waist to chest, allowing users to perform push-pull operations in various postures, such as upright or slightly bent over. Simultaneously, in the second configuration, the design of the push-pull handles 5 and the U-shaped handles allows two people to perform push and pull actions separately, thus making it more effortless when carrying heavy objects.

[0027] Furthermore, the support frame 13 is symmetrically provided with fixing parts 16 on both sides near the end of the support frame 21. The fixing parts 16 are provided with fixing grooves 161, and the sliding sleeve 221 is engaged in the fixing grooves 161 to fix the support frame 21. During use, regardless of its position, the sliding sleeve 221 always remains engaged with the fixing grooves 161, thereby enhancing the stability of the structure.

[0028] In summary, this multi-functional trolley can flexibly change its form according to actual transportation needs, solving the problems of poor adaptability and limited functionality in existing technologies.

[0029] In summary, the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
