Description

[Technical Field]

[0001] This invention relates to a simplified cargo lifting device, and more particularly to a simplified cargo lifting device that allows cargo to be loaded and unloaded easily, quickly, and with little effort, and that can be installed on walls, cargo entrances and exits, or container openings of transport vehicles, and that can raise and lower cargo using an automatic lifting function, allowing cargo to be loaded and unloaded quickly and with little effort. [Background technology]

[0002] With the development of internet technology and the widespread use of electronic devices (e.g., computers, tablets, smartphones), electronic commerce, commonly known as "e-commerce," which allows consumers to conduct online commercial transactions using a single electronic device, has grown remarkably year by year. Accordingly, the cargo transportation and delivery business has also grown rapidly, and it is an important challenge for businesses to make cargo transportation more labor-saving, simple, and fast.

[0003] As e-commerce consumption expands year by year, the transportation industry, which delivers goods from e-commerce sites to consumers, is also busier. Delivery personnel deliver hundreds of items every day. In addition to sorting the items before delivery, they must also manually load and unload the goods, loading and unloading trucks. Delivery personnel repeatedly load and unload goods multiple times a day, which consumes labor and time, and work-related fatigue is a major concern for delivery personnel. Any delivery personnel who work in the delivery industry for a long period of time are at risk of developing occupational diseases. Even if the number of personnel required to load and unload goods from each truck and deliver them is increased, the increased labor costs will reduce the performance and profits of the delivery company.

[0004] Therefore, the main problem that this invention aims to solve is to provide a simple cargo lifting device that allows cargo to be loaded and unloaded easily, quickly, and with little effort, and in particular, can be installed in an appropriate location at an optimal time (for example, on a wall, a cargo entrance or exit, or the container opening of a transport vehicle), thereby supporting delivery personnel and enabling the machine to quickly lift and load and unload cargo. Summary of the Invention [Problem to be solved by the invention]

[0005] SUMMARY OF THE INVENTION The present invention aims to provide a simple cargo lifting device that can be connected to a predetermined object (for example, a wall, a cargo doorway, or a container opening on a transport vehicle). [Means for solving the problem]

[0006] The simplified cargo lifting device comprises a main frame, a slide frame, a support plate, and a drive motor. The main frame is fixedly connected to an object and includes a top rod and a first bottom rod. Two parallel, corresponding first side rods are provided between the top rod and the first bottom rod. The two first side rods of the main frame are provided with corresponding positioning platforms, each with a positioning component facing inward of the main frame. The slide frame is movably connected to the main frame and includes two parallel, corresponding second side rods. A second bottom rod is connected to the bottom of the two second side rods. A first connecting rod is laterally connected between the two second side rods. The two second side rods each have a stopper groove, which faces outward from the main frame body, so that the positioning components on the main frame body are positioned within the stopper groove, and a pulley is provided on the top of the first connecting rod. The support plate is connected to the slide frame body, and a connecting end is provided on one side of the support plate, which is rotatably connected to the bottom of the two second side rods. Thus, the support plate has a mechanism for inverting on the slide frame body, and an interference part is provided on the connecting end of the support plate. The interference part and the second bottom rod of the slide frame body interfere with each other. The drive motor is provided on the top rod of the main frame body, and a cable is wound around the drive motor, and a fixing part is provided on the outside of the drive motor, and one end of the cable is wound around the pulley of the slide frame body and fixedly connected to the fixing part.

[0007] A key technical feature of the present invention is that the main frame body is connected to an object (e.g., a wall, a cargo entrance / exit, or a container opening of a transport vehicle), and the sliding frame body is moved linearly up and down relative to the main frame body, while the loading plate is inverted relative to the sliding frame body, creating a cargo (goods) placement area. This allows cargo (goods) to be appropriately transported from a low position to a high position or vice versa. When the drive motor releases the cable, the sliding frame body moves downward. At this time, a user (e.g., a transport worker) can place the cargo on the loading plate. Next, by controlling the drive motor again to wind up the cable, the sliding frame body moves upward to the required height. This allows cargo to be transported quickly, easily, and with little effort from a low position to a high position. Conversely, when the drive motor winds up the cable, the sliding frame body moves upward. At this time, a user (e.g., a transport worker) can place the cargo on the loading plate. Next, by controlling the drive motor again to loosen the cable, the slide frame body moves downward to a lower position, thereby enabling cargo to be transported from a higher position to a lower position quickly, easily, and with little effort. [Effects of the Invention]

[0008] In this way, the design of this invention can be installed in the right place at the right time to support delivery personnel, and by enabling the machine to quickly lift and load cargo, cargo can be loaded and unloaded quickly, easily, and with little effort, greatly improving the performance of the transportation company.

[0010] Please also refer to Figures 1, 2, 3 and 4. As shown in Figures 1, 2, 3 and 4, the present invention discloses a simple cargo lifting device that is connected to a predetermined object 5 (for example, a wall, a cargo doorway, or a container opening of a transport vehicle). The simple cargo lifting device comprises a main frame body 1, a slide frame body 2, a loading plate 3 and a drive motor 4.

[0011] The main frame body 1 is fixedly connected to the object 5. The main frame body 1 consists of a top rod 11 and a first bottom rod 12, and two parallel corresponding first side rods 13 are provided between the top rod 11 and the first bottom rod 12. The two first side rods 13 of the main frame body 1 are respectively provided with a plurality of corresponding positioning platforms 14, and each positioning platform 14 is provided with a positioning component 15. The positioning components 15 face the inside of the main frame body 1. The positioning platform 14 may be provided with a bore 141, and one end of the positioning component 15 is provided with a screw 151. The positioning component 15 is drilled into the bore 141 of the positioning platform 14 by the screw 151, and then fixed to the screw 151 by a predetermined nut 152, thereby being fixed to the positioning platform 14. The positioning part 15 can be a cylinder and can rotate on the positioning table 14, or the positioning part 15 can be a cube and can move on the positioning table 14.

[0012] The slide frame body 2 is movably connected to the main frame body 1. The slide frame body 2 includes two parallel corresponding second side rods 21. A second bottom rod 22 is connected between the bottoms of the two second side rods 21, and a first connecting rod 23 is connected laterally between the two second side rods 21. The two second side rods 21 are each provided with a stopper groove 211. The stopper groove 211 faces outward from the main frame body 1 and corresponds to the positioning components 15. This allows the multiple positioning components 15 provided on the main frame body 1 to be positioned inside the stopper groove 211, allowing the slide frame body 2 to move linearly up and down on the main frame body 1. A pulley 231 is provided at the top of the first connecting rod 23. A second connecting rod 24 is further connected laterally between the two second side rods 21, and the second connecting rod 24 is located above or below the first connecting rod 23. For example, the second connecting rod 24 is located above the first connecting rod 23, and the second connecting rod 24 is provided with an opening 241.

[0013] The mounting plate 3 is connected to the slide frame body 2. A connecting end 31 is provided on one side of the mounting plate 3, and the connecting end 31 is rotatably connected to the bottom parts of the two second side rods 21, allowing the mounting plate 3 to rotate on the slide frame body 2. An interference part 32 extends from the connecting end 31 of the mounting plate 3. The interference part 32 interferes with the second bottom rods 22 of the slide frame body 2. As a result, when the mounting plate 3 rotates outward, the interference between the interference part 32 and the second bottom rods 22 of the slide frame body 2 causes the mounting plate 3 and the slide frame body 2 to be at an angle of 85 to 95 degrees, preventing the mounting plate 3 from continuing to rotate downward.

[0014] The drive motor 4 is installed on the top rod 11 of the main frame body 1, and a cable 42 is wound around the drive motor 4, and a fixing part 41 is provided on the outside of the drive motor 4. One end of the cable 42 is wound around and passes through the pulley 231 of the slide frame body 2, and then fixedly connected to the fixing part 41.

[0015] When the second connecting rod body 24 is connected between the two second side rod bodies 21, the cable 42 passes through the opening 241 of the second connecting rod body 24, and then is wound around and passed through the pulley 231 of the slide frame body 2, and then is fixedly connected to the fixed part 41.

[0016] When the drive motor 4 is controlled to loosen the cable 42 (for example, the drive motor 4 is controlled to rotate in the opposite direction), the slide frame body 2 descends. Conversely, when the drive motor 4 is controlled to wind up the cable 42 (for example, the drive motor 4 is controlled to rotate in the forward direction), the cable 42 gradually shortens, and the slide frame body 2 moves upward and rises.

[0017] In summary, this invention is explained using an application example. The main frame body 1 can be connected to a predetermined object 5 (e.g., the container opening gate of a transport vehicle). A user (e.g., a transport worker) first flips the loading plate 3 outward to a horizontal position, then controls the drive motor 4 to loosen the cable 42, causing the sliding frame body 2 to move downward. At this time, cargo 6 is placed on the loading plate 3, and the drive motor 4 is further controlled to wind up the cable 42, causing the sliding frame body 2 to move upward. When the loading plate 3 reaches the same height as the container opening of the transport vehicle, the cargo 6 is simply pushed into the container, completing the cargo's transportation from a lower position to a higher position.

[0018] Conversely, by controlling the drive motor to wind up the cable 42, the slide frame body 2 moves upward. At this time, by placing cargo 6 on the loading plate 3 and controlling the drive motor 4 to loosen the cable 42, the slide frame body 2 moves downward. When the loading plate 3 reaches a low position, the cargo can be easily lowered to the low position, completing the transportation of the cargo from the high position to the low position.

[0019] It should be noted that when the loading plate 3 is inverted outward to a horizontal position and the slide frame body 2 is controlled by the drive motor 4 to continue to rise, the interference portion 32 provided on the loading plate 3 comes into contact with the first bottom rod body 12 of the main frame body 1, causing the loading plate 3 to be inverted inward, thereby automatically folding.

[0020] Therefore, the main technical features of this invention are as follows: By connecting the main frame body 1 to an object 5 (for example, a wall, a cargo entrance or exit, or a container opening on a transport vehicle), and sliding the slide frame body 2 up and down relative to the main frame body 1, cargo can be transported from a high position to a low position or from a low position to a high position. Furthermore, by rotating the loading plate 3 outward relative to the slide frame body 2, it can be used as a placement area for cargo 6 (goods). When the cable 42 is wound up or loosened by the drive motor 4, the slide frame body 2 moves linearly up and down, allowing cargo to be loaded and unloaded quickly, easily, and with little effort.
