[0002] In modern industrial production, warehousing and logistics, and construction, material transport trolleys are indispensable auxiliary tools. With increasing demands for space utilization efficiency and transportation flexibility, foldable material transport trolleys are gaining popularity due to their ease of storage and portability. These trolleys effectively reduce space occupation when not in use, improving site utilization, and are convenient for handling and storage during transportation, meeting diverse usage scenarios.

[0003] Currently, the most common material transport trolleys on the market are made into a whole by welding or bolting, and move by relying on the casters at the bottom. They use a load-bearing plate to carry materials. During transportation, the operator controls the direction and movement of the trolley by pushing a handle.

[0004] However, traditional material transport trolleys mostly use fixed structures for their frames and handles, which take up a lot of space when not in use, resulting in reduced space utilization and increased transportation costs and storage difficulties. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a foldable material transport trolley, which aims to improve the problem that traditional material transport trolleys, due to their mostly fixed structure design for the frame and handle, occupy a large space when not in use, resulting in reduced space utilization, increased transportation costs, and storage difficulties.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a foldable material transport trolley, including a support plate, a base fixedly connected to one side of the outer wall of the support plate, a rotating rod fixedly connected to the outer wall of the base, a bracket rotatably connected to the outer wall of the rotating rod, a push handle fixedly connected to the inner wall of the bracket, and an adjustment component provided inside the support plate;

[0007] The adjustment assembly includes a slider, the outer wall of which is slidably connected to the inside of a support plate. A second rotating shaft is fixedly connected to the outer wall of the slider. A connecting rod is fixedly connected to the outer wall of the second rotating shaft. A first rotating shaft is fixedly connected to one end of the connecting rod. A connecting column is slidably connected inside the support plate. A button is fixedly connected to one end of the connecting column. A locking block is fixedly connected to the other end of the connecting column. A spring is sleeved on the outer wall of the connecting column.

[0008] Furthermore, a rotating shaft three is fixedly connected inside the bearing plate, and a connecting rod two is rotatably connected to the outer wall of the rotating shaft three. Both ends of the connecting rod two are fixedly connected to fixed columns, and a connecting rod one is fixedly connected to the outer wall of the fixed columns. An extension plate is fixedly connected to one end of the connecting rod one, and a handle is fixedly connected to the outer wall of the extension plate. A guide rail is slidably connected to the lower surface of the extension plate.

[0009] Furthermore, a fixing block is fixedly connected to the outer wall of the bearing plate, and a pin is slidably connected inside the fixing block, with the outer wall of the pin slidably connected inside the extension plate.

[0010] Furthermore, the lower surface of the support plate is provided with casters, and the push handle is provided at the end of the bracket.

[0011] Furthermore, one end of the rotating shaft is fixedly connected to the outer wall of the bracket, and the button is located above the support plate.

[0012] Furthermore, one end of the spring is fixedly connected to the outer wall of the block, and the other end of the spring is fixedly connected to the inner wall of the support plate.

[0013] Furthermore, the connecting rods are disposed on both sides of the outer wall of the bearing plate, and the outer wall of the card block is slidably connected to the inside of the slider.

[0014] Furthermore, the outer wall of the extension plate is slidably connected to the inside of the support plate, and the guide rail is disposed inside the support plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by pressing the button above the support plate, the connecting column causes the locking block to disengage from the slider and unlock. Subsequently, the bracket rotates and folds around the rotating rod as an axis. During the process, the slider slides in the slide groove of the support plate through the first rotating shaft, the connecting rod, and the second rotating shaft, thereby achieving the effect of folding and storage.

[0017] 2. In this utility model, by pulling the handle, the extension plate slides along the inner guide rail of the bearing plate. The first linkage rod drives the second linkage rod to rotate around the third pivot through the fixed column, ensuring that the extension plate slides out smoothly. The inserted pin passes through the fixed block and is fixed to the hole of the extension plate to prevent shaking, thus achieving the effect of stable transportation of large-sized materials.

[0025] 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.

[0026] Reference Figure 1 - Figure 5 The present invention provides an embodiment of a foldable material transport trolley, comprising a support plate 1, which serves as the main support platform for placing materials to be transported. A base 5 is fixedly connected to one side of the outer wall of the support plate 1, and a rotating rod 6 is fixedly connected to the outer wall of the base 5. The rotating rod 6 serves as the axis for the rotation and folding of the support 4, enabling the support 4 to rotate flexibly around it, thereby realizing the folding and unfolding operation of the trolley. The support 4 is rotatably connected to the outer wall of the rotating rod 6, and a push handle 3 is fixedly connected to the inner wall of the support 4, providing a force application point for the operator to easily control the movement direction and speed of the trolley. An adjustment component is provided inside the support plate 1.

[0027] The adjustment assembly includes a slider 15, whose outer wall is slidably connected to the inside of the support plate 1. A rotating shaft 9 is fixedly connected to the outer wall of the slider 15. The slider 15 ensures that the support 4 can move according to design requirements. A connecting rod 8 is fixedly connected to the outer wall of the rotating shaft 9. The connecting rod 8 transmits the force generated by the rotation of the support 4, thereby controlling the folding and unfolding states of the support 4 and ensuring the continuity of movement of each component. A rotating shaft 7 is fixedly connected to one end of the connecting rod 8. A connecting post 16 is slidably connected inside the support plate 1. A button 10 is fixedly connected to one end of the connecting post 16, and a locking block 18 is fixedly connected to the other end of the connecting post 16. A spring 17 is fitted on the outer wall of the 6th bearing plate 1. A rotating shaft 20 is fixedly connected inside the bearing plate 1. A connecting rod 23 is rotatably connected to the outer wall of the rotating shaft 20. A fixed column 21 is fixedly connected to both ends of the connecting rod 23. A connecting rod 22 is fixedly connected to the outer wall of the fixed column 21. An extension plate 12 is fixedly connected to one end of the connecting rod 22. The extension plate 12 increases the bearing area by sliding out, which can transport more or larger materials. A handle 13 is fixedly connected to the outer wall of the extension plate 12. The handle 13 provides a force point for the operator to control the extension and retraction of the extension plate 12. A guide rail 11 is slidably connected to the lower surface of the extension plate 12.

[0028] Reference Figure 1 - Figure 5 A fixing block 14 is fixedly connected to the outer wall of the support plate 1. A pin 19 is slidably connected inside the fixing block 14. The pin 19 is used to fix the extension plate 12. The outer wall of the pin 19 is slidably connected inside the extension plate 12. A caster wheel 2 is provided on the lower surface of the support plate 1. The caster wheel 2 realizes the movement and steering function of the trolley. The push handle 3 is located at the end of the bracket 4. One end of the pivot 7 is fixedly connected to the outer wall of the bracket 4. The button 10 is located above the support plate 1. One end of the spring 17 is fixedly connected to the outer wall of the locking block 18. The other end of the spring 17 is fixedly connected to the inner wall of the support plate 1. The elastic force of the spring 17 causes the locking block 18 to reset, re-insert the slider 15, and lock the slider 15 to ensure the stability of the bracket 4 in the unfolded state and prevent the bracket 4 from folding accidentally. The connecting rod 8 is set on both sides of the outer wall of the support plate 1. The outer wall of the locking block 18 is slidably connected to the inside of the slider 15. The outer wall of the extension plate 12 is slidably connected to the inside of the support plate 1. The guide rail 11 is set inside the support plate 1. The guide rail 11 provides guidance and support for the sliding of the extension plate 12.

[0029] Working principle: When a foldable material transport trolley is needed to transport materials, the operator first pulls handle 13 to slide the extension plate 12 on the guide rail 11 inside the support plate 1. At the same time, linkage rod 1 22 drives linkage rod 23 to rotate around the pivot 3 20 through the fixed column 21, ensuring that the extension plate 12 can smoothly slide out of the support plate 1 along the guide rail 11, achieving flexible extension and retraction. After the extension plate 12 is pulled out to the appropriate position, the pin 19 is inserted into the corresponding hole reserved in the fixing block 14 and the extension plate 12 to firmly fix the extension plate 12 and prevent it from shaking or shifting during transportation. Then, the materials are placed on the large-area platform formed by the support plate 1 and the extension plate 12, and the omnidirectional wheels 2 are used to push the trolley to transport the materials. The improved transportation efficiency and load-bearing capacity, coupled with the ability to fold up the trolley after use, allows for easy storage. Pressing the button 10 on the top of the support plate 1 causes the connecting column 16 to move downwards within the support plate 1, disengaging the locking block 18 at the end of the connecting column 16 from the slider 15. Once unlocked, the bracket 4 can rotate and fold around the rotating rod 6. During folding, the bracket 4 drives the connecting rod 8 via the first rotating shaft 7, which in turn drives the second rotating shaft 9, allowing the slider 15 to slide smoothly within the pre-set groove inside the support plate 1. As the bracket 4 rotates, the push handle 3 gradually lowers until the bracket 4 and push handle 3 are in contact with the support plate 1, completing the folding and storage process. This effectively reduces the space occupied by the trolley, facilitating storage and transportation.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
