Description

Technical Field

[0001] This utility model relates to the field of material handling technology, and in particular to a retractable oil drum truck. Background Technology

[0002] A drum cart is a tool used to transport round products such as oil drums, wooden barrels, and flower pots. Typically, drum carts have a fixed cross-shaped structure and are not extendable or adjustable. Therefore, they cannot be adjusted to accommodate products of different diameters. When handling large products, the drum cart becomes unusable, requiring replacement or the purchase of a larger cart. Conversely, when handling small products, the cart's inability to retract causes the products to slide, sometimes resulting in some products tipping over due to excessive misalignment between their bottoms and the cart's center, ultimately leading to damage. Summary of the Invention

[0003] The technical problem to be solved by this utility model embodiment is to provide a retractable oil drum cart, which solves the problem that existing oil drum carts cannot be adjusted to adapt to different products.

[0004] In order to solve the above-mentioned technical problems, the present invention provides a telescopic oil drum truck, including a first double-end telescopic component (10) and a second double-end telescopic component (20). Both the first double-end telescopic component (10) and the second double-end telescopic component (20) are long strip structures, and both ends are telescopic ends that can be extended or shortened in their respective length directions. The two are fixedly connected at the center to form a cross shape, and universal wheels (30) are installed at the lower part of each telescopic end of the first double-end telescopic component (10) and the second double-end telescopic component (20).

[0005] The lower end face of the center position of the first double-ended telescopic component (10) is provided with an upper concave notch (11), and the upper end face of the center position of the second double-ended telescopic component (20) is provided with a lower concave notch (21).

[0006] The depth of the upper concave notch (11) is half the thickness of the first double-ended telescopic component (10), and the depth of the lower concave notch (21) is half the thickness of the second double-ended telescopic component (20). The thicknesses of the first double-ended telescopic component (10) and the second double-ended telescopic component (20) are equal. Therefore, when the first double-ended telescopic component (10) and the second double-ended telescopic component (20) are connected through the upper concave notch (11) and the lower concave notch (21), the upper surfaces of the first double-ended telescopic component (10) and the second double-ended telescopic component (20) are flat, and the lower surfaces of the first double-ended telescopic component (10) and the second double-ended telescopic component (20) are also flat.

[0007] The first double-ended telescopic assembly (10) includes a first double vertical plate (12) with an upper concave notch (11) and a first fastener (13) with an upper concave notch (11). The length of the first fastener (13) is greater than the width between the first double vertical plates (12), that is, greater than the length of the upper concave notch (11). The first double vertical plate (12) passes through the lower part or the middle of the first fastener (13) and locks the first double vertical plate (12) and the first fastener (13) together on both sides of the upper concave notch (11).

[0008] The first double-ended telescopic assembly (10) is also provided with a first telescopic plate (14) at both ends. The plate surface of the first telescopic plate (14) is at the same height as the first fastener (13). The first telescopic plate (14) is provided with a longitudinal first sliding groove (14a) on both sides. The first sliding groove (14a) is locked and fixed by the fastening screw on the first double upright plate (12).

[0009] The second double-ended telescopic assembly (20) includes a second double upright plate (22) with a recessed notch (21) and a second fastener (23) with a recessed notch (21). The length of the second fastener (23) is greater than the width between the second double upright plates (22), that is, greater than the length of the recessed notch (21). The second double upright plate (22) passes through the upper part or the middle of the second fastener (23) and locks the second double upright plate (22) and the second fastener (23) on both sides of the recessed notch (21).

[0010] The second double-ended telescopic assembly (20) is also provided with a second telescopic plate (24) at both ends. The plate surface of the second telescopic plate (24) is at the same height as the first fastener (13). The two sides of the second telescopic plate (24) are respectively provided with a longitudinal second slide groove (24a). The second slide groove (24a) is locked and fixed by the fastening screw on the second double upright plate (22).

[0011] The first fastener (13) and the second fastener (23) are fixedly connected by multiple vertical screws.

[0012] The caster wheel (30) is fixedly installed on the lower part of the first telescopic plate (14) and the second telescopic plate (24).

[0013] The telescopic oil drum cart provided by this utility model features telescopic plates at both ends of the first and second double-end telescopic components. These components are fixed at the center with fasteners, ensuring equal height between the fasteners and the four telescopic plates. This design, while adding a telescopic feature, also ensures equal height of the load-bearing parts throughout the cart. The combination of the double-plate structure and fasteners ensures good overall load-bearing capacity even with the added telescopic structure. Furthermore, the telescopic structure allows for adaptation to the handling needs of different products, with the position of the telescopic plates adjusted according to the product's dimensions.

[0020] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] like Figure 1-6 As shown, this utility model provides a telescopic oil drum cart, including a first double-ended telescopic component 10 and a second double-ended telescopic component 20. Both the first double-ended telescopic component 10 and the second double-ended telescopic component 20 are elongated structures, with telescopic ends that can extend or shorten in their respective length directions. They are fixedly connected at the center to form a cross shape, and universal wheels 30 are installed at the lower part of each telescopic end of the first double-ended telescopic component 10 and the second double-ended telescopic component 20. This utility model is formed by connecting the first double-ended telescopic component 10 and the second double-ended telescopic component 20 through a cross-shaped fixed connection, and both ends of the first double-ended telescopic component 10 and the second double-ended telescopic component 20 are provided with telescopic structures, which can be extended and adjusted to adapt to the handling of products of different sizes. The first double-ended telescopic component 10 and the second double-ended telescopic component 20 mainly adopt a square tube structure, which makes the structure simple and stable and can bear greater weight.

[0024] The first double-ended telescopic component 10 has an upper concave notch 11 on its lower center surface, and the second double-ended telescopic component 20 has a lower concave notch 21 on its upper center surface. The telescopic oil drum cart provided in this embodiment connects the first double-ended telescopic component 10 and the second double-ended telescopic component 20 through an adaptive upper and lower notch design. This ensures that the upper surfaces of the interconnected first double-ended telescopic component 10 and the second double-ended telescopic component 20 are on the same plane. While implementing the telescopic design, it ensures that all support positions of the telescopic oil drum cart are on the same plane, thus providing a stable and reliable support platform for the transported products.

[0025] The depth of the upper concave notch 11 is half the thickness of the first double-ended telescopic component 10, and the depth of the lower concave notch 21 is half the thickness of the second double-ended telescopic component 20. Since the thicknesses of the first double-ended telescopic component 10 and the second double-ended telescopic component 20 are equal, when they are joined together through the upper and lower concave notches 11 and 21, their upper and lower surfaces are flush. This notch-joint structure design ensures that both the upper and lower surfaces of the first double-ended telescopic component 10 and the second double-ended telescopic component 20 are flush, providing a flat surface for the transported product and a good planar support platform for the bottom casters 30. This also ensures that the four casters 30 are at the same height and are on the same dimensional plane.

[0026] The first double-ended telescopic assembly 10 includes a first double vertical plate 12 with an upper concave notch 11 and a first fastener 13 with an upper concave notch 11. The length of the first fastener 13 is greater than the width between the first double vertical plates 12, that is, greater than the length of the upper concave notch 11. The first double vertical plate 12 passes through the lower part or the middle of the first fastener 13 and locks the first double vertical plate 12 and the first fastener 13 together on both sides of the upper concave notch 11.

[0027] The first double-ended telescopic assembly 10 is also provided with a first telescopic plate 14 at both ends. The plate surface of the first telescopic plate 14 is at the same height as the first fastener 13. The first telescopic plate 14 is provided with a longitudinal first sliding groove 14a on both sides. It is locked and fixed to the first sliding groove 14a by fastening screws on the first double vertical plate 12.

[0028] The second double-ended telescopic assembly 20 includes a second double upright plate 22 with a recessed notch 21 and a second fastener 23 with a recessed notch 21. The length of the second fastener 23 is greater than the width between the second double upright plates 22, that is, greater than the length of the recessed notch 21. The second double upright plate 22 passes through the upper part or the middle of the second fastener 23 and locks the second double upright plate 22 and the second fastener 23 together on both sides of the recessed notch 21.

[0029] The second double-ended telescopic assembly 20 is also provided with a second telescopic plate 24 at both ends. The plate surface of the second telescopic plate 24 is at the same height as the first fastener 13. The two sides of the second telescopic plate 24 are respectively provided with a longitudinal second sliding groove 24a, which is locked and fixed to the second sliding groove 24a by the fastening screws on the second double vertical plate 22.

[0030] The upper and lower surfaces of the first double-sided plate 12 of the first double-ended telescopic assembly 10 and the second double-sided plate 22 of the second double-ended telescopic assembly 20 are at the same height, so that the upper and lower surfaces of the telescopic plates fitted at both ends of the first double-ended telescopic assembly 10 and the second double-ended telescopic assembly 20 can also be at the same height. The telescopic plates are square tubes, providing an upper support surface for supporting the transported product and a lower support surface for mounting casters. Sliding grooves are also provided on both sides for sliding contact with each double-sided plate. The telescopic drum cart provided by this utility model forms the skeleton structure of the entire telescopic drum cart through the first double-sided plate 14 and the second double-sided plate 24. The four end telescopic plates are fitted onto the skeleton structure and can slide and extend along the skeleton structure. They are fixed together with fastening screws, thus stabilizing the structure of the entire telescopic drum cart and allowing it to carry the transported product through telescopic adjustment.

[0031] It should be noted that each telescopic plate is also provided with an upwardly protruding end plate. This end plate not only provides an external limit for the telescopic plate relative to the double vertical plates, serving as the extension and retraction stop point of the telescopic plate, but also provides limit protection for the transported products, preventing the transported products from sliding.

[0032] The first fastener 13 and the second fastener 23 are fixedly connected by multiple vertical screws.

[0033] The caster wheel 30 is fixedly installed on the lower part of the first telescopic plate 14 and the second telescopic plate 24.

[0034] The telescopic oil drum cart provided by this utility model features telescopic plates at both ends of the first and second double-end telescopic components. These components are fixed at the center with fasteners, ensuring equal height between the fasteners and the four telescopic plates. This design, while adding a telescopic feature, also ensures equal height of the load-bearing parts throughout the cart. The combination of the double-plate structure and fasteners ensures good overall load-bearing capacity even with the added telescopic structure. Furthermore, the telescopic structure allows for adaptation to the handling needs of different products, with the position of the telescopic plates adjusted according to the product's dimensions.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
