Description

Technical Field

[0001] This invention relates to the field of cabinet-type trolleys, specifically a multi-functional trolley. Background Technology

[0002] Trolleys are widely used material storage and transfer equipment in industrial production, warehousing and logistics, and daily operations. With their flexible mobility and convenient storage, they have become an important tool for various places to achieve classified storage and efficient transfer of goods.

[0003] Multifunctional trolleys integrate storage structures such as lockers and drawers on top of basic mobility functions. The cabinets are usually reinforced with ribs and fixing strips to improve structural stability. Some also have a work surface on top, which can meet multiple needs such as item storage and temporary operation at the same time. The adaptability and practicality are greatly improved, and they are widely used in workshop material transfer, warehouse goods sorting, and daily tool storage.

[0004] These types of trolleys typically feature several drawers within their storage compartments, allowing for categorized storage and more organized retrieval and organization of items. However, in practical use, the drawers of conventional multi-functional trolleys are often of fixed sizes, making it difficult to accommodate items of different sizes and shapes. Furthermore, dust and debris tend to accumulate at the bottom of the drawers, and cleaning the corners is challenging. The existing structure struggles to balance the needs for flexible space adjustment, easy cleaning, and protective transport. Therefore, targeted optimization of the drawer structure of multi-functional trolleys is crucial for improving their overall performance.

[0005] Therefore, it is urgent to optimize the drawer structure design to improve the overall practicality and adaptability of the multi-functional trolley. Summary of the Invention

[0006] To address the problems in the existing technology, this invention provides a multifunctional trolley with a medical integrated injection-molded cabinet structure, which solves the problem that existing trolley drawers mostly only have basic storage functions and cannot simultaneously meet the comprehensive needs of space adjustment and item protection.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A multi-functional trolley with a medical integral injection molded cabinet structure includes a storage cabinet with universal wheels around the bottom. The storage cabinet is equipped with reinforcing ribs around its perimeter to enhance the stability of the cabinet and fixing strips to support the frame structure. Several drawers are movably installed inside the storage cabinet. In addition, it includes a top plate, which is installed on the top of the storage cabinet and has a recessed working surface inside.

[0008] The drawers are all the same width and are installed in sequence from top to bottom on one side of the storage cabinet; The height of the drawers increases from top to bottom, creating a multi-item storage layout.

[0009] The drawer bottom plate is removably installed.

[0010] Specifically, a support frame is movably installed at the bottom of the drawer, with the bottom plate located inside the support frame. The support frame is flexibly connected to the inner surface of the drawer by several elastic rubber strips, and a lifting spring is connected between the support frame and the exposed surface of the drawer.

[0011] Specifically, the middle of the tray is provided with a protrusion that is embedded in the drawer sidewall to prevent the tray from shifting back and forth.

[0012] Specifically, an elastic strap is inserted and installed at the top of the protrusion, and the strap is located inside the drawer.

[0013] Specifically, a support rod is hinged to the bottom of the protrusion, and a torsion spring is provided at the hinged part of the support rod. In its natural state, the axis of the support rod is parallel to the plane of the support frame and is used to support the bottom plate.

[0014] Specifically, the outer edge of the base plate slides against the inner wall of the support frame.

[0015] Specifically, the base plate is a two-section splicing structure. The splicing parts of the two base plates are staggered with toothed openings. A locking plate for locking the two base plates is slidably installed in the middle of the support frame, and the locking plate is provided with toothed tongues that are compatible with the toothed openings.

[0016] Specifically, when the card plate is moved along the plane of the support frame, the toothed tongue engages with the toothed mouths on both sides in succession.

[0017] Specifically, pins are fixedly installed on the card plate, and the ends of the pins are embedded in the base plate to keep the two base plates flat.

[0018] Specifically, the support rod has a support groove on the side facing the base plate, and a support piece that engages with the support groove is provided on the side wall of the base plate.

[0019] Specifically, an elastic curtain is slidably installed on the bottom plane of the base plate. The two ends of the curtain are fixed to the bottom of the two base plates respectively. When the two base plates are misaligned, the curtain is elastically stretched and used to cover the misalignment gap.

[0020] Specifically, the exposed surface of the drawer is provided with a transparent panel.

[0021] The beneficial effects of this invention are: The drawer structure design of this invention offers multiple advantages, including adjustable space, convenient cleaning, and damage prevention during transport. Through the combination of a two-section base plate, a tray, and a support rod, the internal volume of the drawer can be flexibly adjusted. It utilizes the space of the lower drawer to meet the storage needs of large items, adapting to diverse storage scenarios. The designed support frame, with its elastic connection structure, allows the base plate to tilt and rotate, achieving thorough cleaning of the drawer bottom and significantly improving cleaning efficiency and cleanliness. Built-in elastic straps effectively secure items inside the drawer, preventing them from scattering during transport and enhancing transportation stability. Simultaneously, the transparent panel facilitates quick identification of items, and the strong interoperability of the various structures makes operation simple, comprehensively improving the storage practicality and ease of use of the trolley.

[0024] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0025] The present invention provides a multi-functional trolley with a medical integrated injection-molded cabinet structure, which solves the problem that existing trolley drawers only have basic storage functions and cannot simultaneously meet the comprehensive needs of space adjustment and item protection. like Figures 1 to 3 As shown, a multi-functional trolley with a medical integrated injection-molded cabinet structure includes an integrally pressed storage cabinet 1 with casters around its bottom. Reinforcing ribs 11 are provided around the integrally pressed storage cabinet 1 to enhance its stability, and fixing strips 12 are provided to support the frame structure. The fixing strips 12 enhance the frame stability of the integrally pressed storage cabinet 1 during injection molding and can be removed after molding. Several drawers 2 are movably installed inside the integrally pressed storage cabinet 1. In addition, a top plate 3 is included, which is installed on the top of the integrally pressed storage cabinet 1 and has a recessed working surface for placing common instruments or frequently accessed items.

[0026] The drawers 2 are of the same size and are installed in sequence from top to bottom on one side of the integrated press-fit storage cabinet 1. In addition, the overall height of the drawers 2 can be varied according to the usage scenario, such as increasing from top to bottom to form a multi-item storage pattern.

[0027] like Figure 4 and Figure 5 As shown, the drawer 2 is movably equipped with a base plate 5, and a support frame 4 is movably installed at the bottom of the drawer 2. The base plate 5 is located inside the support frame 4. The support frame 4 and the inner surface of the drawer 2 are flexibly connected by several elastic rubber strips 41. A hidden lifting spring 42 is connected between the support frame 4 and the exposed surface of the drawer 2.

[0028] In practical use, under the traction of spring 42, the support frame 4 is tightly attached to the bottom of drawer 2. At this time, the bottom plate 5 is in a horizontal and flat state, forming a storage space with the drawer 2. During later maintenance, when it is necessary to clean and maintain drawer 2, the operator presses down the support frame 4 on the same side as spring 42, so that it gradually separates from the bottom of drawer 2. At this time, under the flexible connection of rubber strip 41, the support frame 4 at this end only shifts, so that the support frame 4 and the bottom of drawer 2 form an acute angle. At this time, the bottom plate 5 is in a tilted and deflected state under the limiting action of support frame 4. The notch at the bottom of drawer 2 opens, and the debris or dust accumulated or scattered at the bottom of drawer 2 slides outward from this notch. In the open state, the dead corners of the bottom of drawer 2 disappear, and a comprehensive cleaning operation can be carried out on the bottom of drawer 2, improving efficiency and cleanliness. After cleaning, the downward pressure on support frame 4 is manually released, and then spring 42 returns to its original position and drives support frame 4 to return to its original position.

[0029] like Figure 5 and Figure 7As shown, the middle part of the support frame 4 is provided with a protrusion 43 that is embedded in the side wall of the drawer 2 to prevent the support frame 4 from shifting back and forth, thereby improving the stability of the overall frame structure of the drawer 2.

[0030] like Figure 4 and Figure 6 As shown, an elastic strap 44 is inserted and installed at the top of the protrusion 43, and the strap 44 is located in the inner space of the drawer 2.

[0031] When necessary, use straps 44 to secure the items inside drawer 2 to prevent them from bumping or falling during transport and to improve transport stability.

[0032] like Figures 5 to 9 As shown, a support rod 45 is hinged to the bottom of the protrusion 43. A torsion spring is provided at the hinged part of the support rod 45. In its natural state, the axis of the support rod 45 is parallel to the plane of the support frame 4 and is used to support the bottom plate 5. The outer edge of the bottom plate 5 slides against the inner wall of the support frame 4.

[0033] The base plate 5 is a two-section splicing structure. The splicing parts of the two base plates 5 are staggered with toothed openings 51. A locking plate 6 for locking the two base plates 5 is slidably installed in the middle of the support frame 4. The locking plate 6 is provided with a toothed tongue 61 that matches the toothed openings 51. When the locking plate 6 is pulled along the plane of the support frame 4, the toothed tongue 61 engages with the toothed openings 51 on both sides. A pin 62 is fixedly installed on the locking plate 6. The end of the pin 62 is embedded in the base plate 5 to keep the two base plates 5 flat. A groove 46 is provided on the side of the support rod 45 facing the base plate 5. A support piece 52 that engages with the groove 46 is provided on the side wall of the base plate 5.

[0034] During operation, in the initial state, the card plate 6 is fully embedded in the support frame 4. At this time, the upper plane of the card plate 6 is flush with the plane of the bottom plates 5 on both sides. At this time, the toothed tongue 61 is in the first working position and does not engage with the toothed mouth 51 on the bottom plates 5 on both sides. The toothed tongue 61 is used to support and fix the locking state of the bottom plate 5. When the items to be placed exceed the volume of the drawer 2, the operator pulls out the card plate 6 step by step. At this time, the toothed tongue 61 moves from the first working position to the second working position and engages with the toothed mouth 51 on one side of the bottom plate 5, thereby releasing the support function of the middle of the bottom plate 5 on this side. At this time, the operator presses the bottom plate 5 on this side downward, causing the two bottom plates 5 to be relatively misaligned. At the same time, the volume of the inner space of the drawer 2 on the pressed side increases. Similarly, by continuing to pull out the card plate 6 to enter the third working position, the support function of the bottom plate 5 on the other side can be released. Under this adjustment, the bottom plate 5, pressed down, enters the lower drawer, thereby using the volume of the lower drawer 2 to compensate for the insufficient volume of the upper drawer 2, for placing large items. During the downward pressing and moving of the bottom plate 5, the support rod 45 is squeezed and gradually changes from a horizontal to a vertical position. The torsion of the torsion spring and the interlocking action between the support groove 46 and the support piece 52 are used to clamp and lock the height position of the bottom plate 5 after the position adjustment. After the position adjustment of the bottom plate 5 is completed, the clamping plate 6 can be pushed back to the first position without affecting the placement of large items; otherwise, it can be taken out and placed in another drawer 2 for storage.

[0035] like Figure 6 As shown, an elastic curtain 53 is slidably installed on the bottom plane of the base plate 5. The two ends of the curtain 53 are respectively fixed to the bottom of the two sections of the base plate 5. When the two sections of the base plate 5 are misaligned, the curtain 53 is elastically stretched and used to cover the misalignment gap.

[0036] When only one side of the base plate 5 is adjusted, the curtain 53 and the base plate 5 form a "Z" shaped folding structure, thereby compensating for the misalignment gap and preventing items from falling. The misalignment gaps on the other three sides of the lower base plate 5 can be sealed by the inner wall of the lower drawer 2.

[0037] like Figure 4 and Figure 8 As shown, the exposed surface of the drawer 2 is provided with a transparent panel 21, which makes it easy to know the type and attributes of the items placed inside without opening the drawer 2, thus improving the convenience of access.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
