Description

Technical Field

[0001] This utility model relates to the field of object transfer pulley technology, and in particular to a multifunctional adjustable object transfer pulley. Background Technology

[0002] A material handling pulley is an auxiliary tool used in factories, warehouses, and other places to move and transport various items. It features a simple structure, easy operation, and high load-bearing capacity. This pulley typically consists of a load-bearing platform, a support frame, pulley assemblies, and an operating handle. It can effectively and smoothly transfer heavy objects from one location to another, reducing manual labor and improving handling efficiency.

[0003] A Chinese patent has been published: a liftable flatbed cart, patent announcement number: CN218805893U. This patent features a connecting rod and a slider that are hinged between the seat and the lifting plate. The slider is slidably disposed inside a groove in the seat, and a screw threadedly connected to the slider is provided on the seat. When the screw rotates, it can control the slider to move inside the groove.

[0004] While this type of pallet trolley solves the problem of reduced handling efficiency caused by the fixed height design of traditional trolleys, it still suffers from drawbacks such as a fixed structure, large footprint, and inconvenient storage, making it unsuitable for equipment storage and handling. Furthermore, when transporting objects of varying sizes, traditional pallet trolleys, lacking flexible load-bearing structure adjustments, often experience object swaying or even falling during transport, posing safety hazards. This is especially true when transporting on slopes or curves, where the lack of effective clamping and restraint protection for goods easily leads to slippage and damage. Therefore, there is an urgent need for a transfer pallet trolley with a retractable structure that can clamp and secure objects according to their size during transport, thereby improving transport stability, meeting diverse handling needs, and enhancing the practicality and safety of the equipment. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a multifunctional adjustable object transfer pulley cart to solve the problems of pulley carts having a fixed structure, inconvenient storage, and lack of effective clamping and limiting protection for goods, which can easily cause items to slip and be damaged.

[0006] To achieve the above objectives, this utility model provides a multifunctional adjustable object transfer pulley cart, including an outer plate. An inner retractable plate for reducing the overall cart area is slidably connected inside the outer plate. A pusher is fixedly connected to the side wall of the inner retractable plate. Two rollers are fixedly connected to the bottom of both the outer plate and the inner retractable plate. The rollers are fixed to one side of the bottom of the outer plate and the inner retractable plate by bolts. A fixing rod is fixedly connected to the top side of both the outer plate and the inner retractable plate. The fixing rods are arranged in pairs facing each other, and a limiting mechanism for preventing goods from collapsing and falling is provided between the pairs of opposing fixing rods.

[0007] Preferably, the limiting mechanism includes two first telescopic stops and two second telescopic stops disposed between the opposing surfaces of the two opposing fixed rods. The two second telescopic stops are rotatably connected to the side walls of the fixed rods. A plurality of equally spaced and uniformly distributed support rods are fixedly connected between the opposing surfaces of the fixed rods on both sides of the top of the outer plate. A sliding rod is slidably inserted through the side wall of the support rod. A first spring is sleeved on the outer wall of the sliding rod. One end of the sliding rod is fixedly connected to a limiting plate. The two ends of the first spring are respectively fixedly connected to the limiting plate and the side wall of the support rod.

[0008] Preferably, two connecting plates are fixedly connected between the opposing surfaces of the two second telescopic stops. Each of the two connecting plates has a sliding groove on its sidewall. Two sliding plates are slidably connected inside the sliding groove. A second spring is fixedly connected between the opposing surfaces of the two sliding plates. A limit post is fixedly connected to one end of each of the two sliding plates. A fixing block is fixedly connected to the sidewall of one of the fixing rods. A gripping rod is fixedly connected between the opposing surfaces of the two sliding plates. Each sidewall of the fixing block has two opposing limit grooves. One end of the limit post is adapted to the inner wall of the limit groove.

[0009] Preferably, the two limiting grooves are L-shaped and the inner walls of the limiting grooves are provided with inclined grooves for limiting the position of the limiting post.

[0010] Preferably, the inner shrink plate has a plurality of equally spaced and uniformly distributed insertion holes on its side wall, the outer plate has a fixed plate fixedly connected to its side wall, the fixed plate has a plug that slides through its side wall, the plug has a third spring sleeved on its outer wall, the two ends of the third spring are respectively fixedly connected to the inner wall of the fixed plate and one end of the plug, and one end of the plug passes through the outer plate and is inserted into the insertion hole.

[0011] Preferably, one end of each of the two grip rods is semi-circular.

[0012] The beneficial effects of this utility model are:

[0013] 1. This multi-functional adjustable object transfer pulley features an adjustable carrying platform composed of an outer plate and a sliding inner retractable plate within its limiting mechanism. This platform can flexibly extend and retract according to the size of the goods, enhancing its adaptability. During the inward retraction of the inner retractable plate, the limiting plate on the side wall of the support rod automatically conforms to the side of the goods and, under the elastic force of the first spring, flexibly clamps the goods, effectively preventing swaying and displacement while avoiding damage due to excessive clamping. Simultaneously, the first and second telescopic stops jointly provide multi-point limiting of the goods, enhancing the overall fixation effect. When unloading, the operator can squeeze the two gripping rods to drive the sliding plate along the slide groove and compress the second spring, thereby disengaging the limiting post from the limiting groove and quickly releasing the limiting structure. This structure not only achieves automatic limiting and flexible clamping of goods during transportation, significantly improving transportation stability and safety, but also greatly enhances the pulley's adaptability to goods of different sizes and ease of storage, demonstrating excellent multi-functionality.

[0014] 2. This multi-functional adjustable object transfer trolley can completely retract its inner retractable panel into the outer panel when not in use, minimizing the platform's footprint and improving space utilization. It is easy to store and fold away when not in use, making it suitable for space-constrained warehouses, workshops, or transport vehicle interiors. This prevents cluttered equipment and blocked passageways. Furthermore, its simple retractable structure and convenient operation allow for quick platform extension and retraction, enhancing flexibility and efficiency. It boasts excellent practicality and portability, meeting diverse handling needs and improving equipment usability. Attached Figure Description

[0024] like Figures 1 to 4 As shown, a multifunctional adjustable object transfer pulley includes an outer plate 1. An inner retractable plate 2 for reducing the overall vehicle area is slidably connected inside the outer plate 1. A pusher 3 is fixedly connected to the side wall of the inner retractable plate 2. Two rollers 4 are fixedly connected to the bottom of both the outer plate 1 and the inner retractable plate 2. The rollers 4 are fixed to one side of the bottom of the outer plate 1 and the inner retractable plate 2 by bolts. A fixing rod 5 is fixedly connected to one side of the top of both the outer plate 1 and the inner retractable plate 2. The fixing rods 5 are arranged in pairs facing each other. A limiting mechanism for preventing the goods from collapsing and falling is provided between the pairs of opposing fixing rods 5.

[0025] Further, see attached document. Figures 1 to 3As shown, the limiting mechanism includes two first telescopic stops 6 and two second telescopic stops 7 disposed between the opposing faces of the two opposing fixed rods 5. The two second telescopic stops 7 are rotatably connected to the side walls of the fixed rods 5. Multiple equidistant and evenly distributed support rods 8 are fixedly connected between the opposing faces of the fixed rods 5 on both sides of the top of the outer plate 1. Sliding rods 9 slide through the side walls of the support rods 8. A first spring 10 is sleeved on the outer wall of the sliding rod 9. One end of the sliding rod 9 is fixedly connected to a limiting plate 11. The two ends of the first spring 10 are respectively fixedly connected to the limiting plate 11 and the side walls of the support rods 8. Two connecting plates 12 are fixedly connected between the opposing faces of the two second telescopic stops 7. The sidewalls of the connecting plate 12 are provided with sliding grooves 13. Two sliding plates 14 are slidably connected inside the sliding grooves 13. A second spring 15 is fixedly connected between the opposite surfaces of the two sliding plates 14. A limiting post 16 is fixedly connected to one end of each of the two sliding plates 14. A fixing block 17 is fixedly connected to the sidewall of one of the fixing rods 5. A gripping rod 18 is fixedly connected between the opposite surfaces of the two sliding plates 14. The sidewalls of the fixing block 17 are provided with two opposing limiting grooves 19. One end of the limiting post 16 is adapted to the inner wall of the limiting groove 19. The two limiting grooves 19 are L-shaped and the inner walls of the limiting grooves 19 are provided with inclined grooves 20 for limiting the position of the limiting post 16.

[0026] First, place the goods on top of the outer panel 1. If the goods are small, push the outer panel 1 or the inner shrink panel 2 to make the inner shrink panel 2 slide inward and retract into the interior of the outer panel 1, thereby reducing the platform area to fit the size of the goods. If the goods are large, stretch the outer panel 1 or the inner shrink panel 2 to make the inner shrink panel 2 extend out from the interior of the outer panel 1 to expand the platform area and achieve the load-bearing adaptation for large-sized goods.

[0027] During the inward retraction of the inner shrink plate 2, the limiting plate 11 set on the side wall of the support rod 8 will contact the side of the goods and apply a slight squeezing force to the goods in conjunction with the push frame 3. At this time, the first spring 10 releases the spring force and pushes the limiting plate 11 to flexibly clamp the goods, thereby improving the fixation stability while ensuring that the goods are not damaged. At the same time, the first telescopic stop bar 6 and the second telescopic stop bar 7 work together to achieve multi-point limiting of the goods, effectively preventing the risk of shaking and falling of the goods during the transfer process.

[0028] By rotating the second telescopic stop bar 7, the limiting post 16 inside it will contact the inclined groove 20 and slide into the limiting groove 19, thereby achieving stable positioning of the second telescopic stop bar 7 and enhancing the stability of the overall limiting structure. When it is necessary to release the limiting state to take out the goods, the handling personnel only need to hold the two gripping rods 18 with one hand and pinch them together. The gripping rods 18 will drive the sliding plate 14 to slide along the sliding groove 13, while compressing the second spring 15. During the movement, the sliding plate 14 will drive the limiting post 16 to disengage from the limiting groove 19, so that the second telescopic stop bar 7 is in a movable state, which makes it easier to take out the goods smoothly. When not in use, the inner retractable plate 2 can be completely stored inside the outer plate 1, so that the carrying platform is in the minimum state, thereby effectively reducing the area occupied by the whole vehicle and improving the space utilization rate.

[0029] The adjustable carrying platform, consisting of an outer plate 1 and a sliding inner retractable plate 2, is incorporated into the limiting mechanism. This platform can flexibly extend and retract according to the size of the goods, enhancing its adaptability. During the inward retraction of the inner retractable plate 2, the limiting plate 11, located on the side wall of the support rod 8, automatically conforms to the side of the goods and, under the elastic force of the first spring 10, flexibly clamps the goods. This effectively prevents the goods from shaking and shifting, and avoids damage caused by excessive clamping. Simultaneously, the first telescopic stop bar 6 and the second telescopic stop bar 7 jointly limit the goods at multiple points, enhancing the overall fixation effect. When unloading the goods, the operator can squeeze the two gripping rods 18 to drive the sliding plate 14 to slide along the slide groove 13 and compress the second spring 15, thereby disengaging the limiting post 16 from the limiting groove 19 and quickly releasing the limiting structure. This structure not only achieves automatic limiting and flexible clamping of goods during transportation, significantly improving transportation stability and safety, but also greatly enhances the adaptability and storage convenience of the pulley cart for goods of different sizes.

[0030] Further, see attached document. Figure 4 As shown, the inner shrink plate 2 has multiple evenly distributed insertion holes 21 on its side wall. The outer plate 1 is fixedly connected to a fixing plate 22. A plug 23 slides through the side wall of the fixing plate 22. A third spring 24 is sleeved on the outer wall of the plug 23. The two ends of the third spring 24 are fixedly connected to the inner wall of the fixing plate 22 and one end of the plug 23, respectively. One end of the plug 23 passes through the outer plate 1 and is inserted into the insertion hole 21. By pulling the plug 23, the third spring 24 is compressed to release the restriction on the inner shrink plate 2. Then the distance between the outer plate 1 and the inner shrink plate 2 can be adjusted. When the inner shrink plate 2 is adjusted to a suitable distance, the plug 23 is released. Then the third spring 24 releases its spring force to push one end of the plug 23 through the interior of the outer plate 1 and into the insertion hole 21, thereby re-restricting the inner shrink plate 2.

[0031] Further, see attached document. Figure 3As shown, one end of each of the two grip rods 18 is semi-circular. The semi-circular shape of the grip rods 18 facilitates the user's grip and releases the limiting relationship between the limiting post 16 and the limiting groove 19.
