Description

Technical Field

[0001] This invention relates to the field of cargo storage technology, and in particular to a handcart with multiple cargo carrying methods. Background Technology

[0002] The core functions of medical trolleys are concentrated in three main areas: item transport, immediate nursing support, and environmental management. They facilitate short-distance transport of items such as medicines, instruments, specimens, and patient clothing, reducing the time cost for medical staff to travel back and forth to retrieve items. They are frequently used, especially between wards, treatment rooms, and laboratories. Some specialized trolleys (such as emergency trolleys and dressing change trolleys) can serve as temporary operating platforms to store emergency equipment or dressing change tools, allowing medical staff to perform treatments, dressing changes, and emergency procedures directly at the patient's bedside, thus improving response speed. Through zoning design (such as clean zones and contaminated zones), medical devices and medicines can be stored separately to avoid cross-contamination. They can also collect medical waste, helping to maintain a clean and compliant treatment environment.

[0003] Traditional handcarts still have many drawbacks in terms of carrying goods, such as: limited and fixed carrying capacity with unclear partitions; limited and single carrying methods, resulting in very fixed specifications and sizes of the goods that can be carried, and limited applicable environments. Summary of the Invention

[0004] The technical problem that this invention aims to solve is that traditional handcarts have limited and fixed carrying capacity and vague partitions, and the carrying methods of handcarts are singular and limited, resulting in very fixed specifications and sizes of applicable items and limited applicable environments.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a handcart with multiple cargo carrying methods, including a main frame, a detachable upper storage box installed on the upper surface of the main frame, rotating adjustment cylinders staggered on both sides of the detachable upper storage box, an internal partition curtain installed inside the rotating adjustment cylinder, and an arc-shaped sunken lateral limiting hook elastically installed on the outer surface of the rotating adjustment cylinder.

[0006] The upper surface of the main frame is hinged with top side limiting hooks on both sides, and the lower ends of both sides of the detachable upper storage box are provided with lateral limiting slots that cooperate with the top side limiting hooks.

[0007] The lower surface of the main frame has downwardly protruding bottom control plates on both sides, and the bottom control plates are threaded with lateral adjustment bolts.

[0008] The detachable top-mounted storage box has strip-shaped assembly ports on both sides for installing rotating adjustment cylinders.

[0009] The inner side of the detachable top-mounted storage box has an integrated arc-shaped guide frame located at the openings on both sides of the strip-shaped assembly port.

[0010] The inner walls on both sides of the strip-shaped assembly port are symmetrically provided with lateral assembly holes for installing a rotating adjusting cylinder. The rotating adjusting cylinder is inserted into the lateral assembly holes through the two side assembly shafts and is movably assembled with the strip-shaped assembly port.

[0011] The outer side of the rotating adjusting cylinder is provided with a strip-shaped telescopic opening and an arc-shaped sinking groove for accommodating the arc-shaped sinking lateral limiting hook.

[0012] The built-in partition roller blind includes an internal elastic roller installed inside a rotating adjusting cylinder, a flexible partition fabric wound around the outside of the internal elastic roller, and an external connecting frame fixed to the outer end of the flexible partition fabric.

[0013] The rotating adjusting cylinder has lateral limiting guide blocks protruding into the arc-shaped guide frame on both sides.

[0014] The detachable top-mounted storage box has a plurality of internal limiting hooks welded and fixed on the inner side corresponding to the horizontal position of the strip assembly opening.

[0015] The beneficial effects of this invention are: (1) The handcart of the present invention has multiple loading modes by installing a split detachable upper storage box on the upper surface of the main frame, and using the side adjustment bolts on the bottom control plate to press the top side limit hook to limit the installation of the detachable upper storage box, which can be quickly loaded, unloaded and replaced as needed, thus improving adaptability. (2) Rotary adjustment cylinders are staggered on both sides of the detachable top storage box. The internal chamber of the detachable top storage box can be divided into storage chambers of different sizes through the built-in partition curtain inside the rotary adjustment cylinder, so that different sizes of items can be placed and the applicability range can be improved. (3) By elastically installing an arc-shaped sunken lateral limit hook on the outside of the rotating adjustment cylinder, an external hook can be formed on the outside by adjusting the angle of the rotating adjustment cylinder, which facilitates the hanging of goods on the outside and improves its cargo carrying method. (4) By welding and fixing a plurality of internal limit hooks on the horizontal position of the corresponding strip assembly opening on the inner side of the detachable upper storage box, the lateral support force of the built-in partition roller shutter after installation can be improved, and the internal safety can be guaranteed. (5) The use of internal flexible support can ensure the shock absorption and safety of the load. Attached Figure Description

[0019] Figure 3 This is a schematic diagram of the rotating adjusting cylinder in this invention. Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] Figure 1 , Figure 2 and Figure 3 The handcart shown includes a main frame 1, a detachable upper storage box 2 installed on the upper surface of the main frame 1, rotating adjustment cylinders 3 staggered on both sides of the detachable upper storage box 2, an internal partition curtain 4 installed inside the rotating adjustment cylinder 3, and an arc-shaped sunken lateral limit hook 5 elastically installed on the outer surface of the rotating adjustment cylinder 3.

[0023] To facilitate separation and fixation, the upper surface of the main frame 1 is hinged with top side limit hooks 6 on both sides, and the lower ends of both sides of the detachable upper storage box 2 are provided with lateral limit slots that cooperate with the top side limit hooks 6.

[0024] To accommodate the bottom control, the lower surface of the main frame 1 has downwardly protruding bottom control plates 7 on both sides, and the bottom control plates 7 have lateral adjustment bolts 8 threaded into their interiors.

[0025] The bottom control plate 7 is located inside the top side limit hook 6. By rotating the lateral adjustment bolt 8, the top side limit hook 6 is squeezed from the inside out. Then the bottom of the top side limit hook 6 is squeezed and the upper end flips and is inserted into the lateral limit slot, thereby limiting and fixing the detachable upper storage box 2 to the upper surface of the main frame 1.

[0026] To facilitate side assembly, the detachable top-mounted storage box 2 has strip-shaped assembly openings on both sides for installing the rotating adjusting cylinder 3.

[0027] The outer arc-shaped surface of the rotating adjusting cylinder 3 should fit as closely as possible to the strip-shaped assembly opening to ensure its internal sealing.

[0028] To improve the stability and positioning of rotation, the inner side of the detachable top-mounted storage box 2 has an integrated arc-shaped guide frame 9 located at the openings on both sides of the strip-shaped assembly port.

[0029] To facilitate the movable assembly, symmetrical side assembly holes for installing the rotating adjusting cylinder 3 are provided on the inner walls of both sides of the strip assembly port. The rotating adjusting cylinder 3 is inserted into the side assembly holes through the side assembly shafts and is movablely assembled with the strip assembly port.

[0030] To facilitate storage and allow the rotating adjusting cylinder 3 to rotate inside the strip-shaped assembly port, a strip-shaped telescopic opening and an arc-shaped recessed groove for storing the arc-shaped recessed lateral limiting hook 5 are provided on the outer side of the rotating adjusting cylinder 3.

[0031] To facilitate flexible winding and unfolding, the built-in partition roller blind 4 includes an internal elastic roller 41 installed inside the rotating adjustment cylinder 3, a flexible partition fabric 42 wound around the outside of the internal elastic roller 41, and an external connecting frame 43 fixed to the outer end of the flexible partition fabric 42.

[0032] The internal elastic roller 41 is elastically assembled at the center of the rotating adjusting cylinder 3 by the coil springs at both ends. People can pull the flexible partition cloth 42 outward by pulling the external connecting frame 43. When an internal partition is needed, people first rotate the rotating adjustment cylinder 3 inward, then pull the external connecting frame 43 to remove the flexible partition cloth 42, thereby forming an independent chamber inside the detachable upper storage box 2, which facilitates partitioning and placement inside.

[0033] To facilitate the guidance and limiting on both sides, the rotating adjusting cylinder 3 has lateral limiting guide blocks 31 protruding into the arc-shaped guide frame 9 on both side walls.

[0034] Lateral limiting guide blocks 31 on both sides of the rotating adjusting cylinder 3 are inserted into the arc-shaped guide frame 9 to improve sliding guidance and limit the maximum flip angle.

[0035] To enhance the stability of the internal installation, a plurality of internal limit hooks 10 are welded and fixed on the inner side of the detachable top-mounted storage box 2 at the horizontal position corresponding to the strip assembly opening.

[0036] Both the outer perimeter of the flexible partition fabric 42 and the inner perimeter of the outer connecting frame 43 are provided with circular limiting holes that cooperate with the inner limiting hooks 10. When the flexible partition fabric 42 is pulled outward, the circular limiting holes on the outer perimeter of the flexible partition fabric 42 and the inner perimeter of the outer connecting frame 43 fit onto the inner limiting hooks 10 at the corresponding positions. In this way, the flexible partition fabric 42 can be tightened by the inner limiting hooks 10 to prevent bending and deformation caused by the pressure of the upper weight, thereby improving the bottom support and stability.

[0037] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
