[0024] As in the Fig. 1 and Fig. As shown in Figure 2, this application provides a sheet metal waste container comprising a container door 100 manufactured by sheet metal fabrication, a lid 200, side walls 300, and rear walls 400; the lid 200 is located at the top of the sheet metal waste container and can be pivotally opened or closed about its pivot axis to allow the user to dispose of waste; the container door 100 is rotatably mounted on the front of the sheet metal waste container to facilitate cleaning or maintenance of the container interior. The two sides of the side walls 300 are each adjacent to the container door 100 and the rear walls 400.

[0025] The sheet metal waste container can form a single receiving space and can form multiple receiving spaces; the drawings of this application show an example of a sheet metal waste container with two receiving spaces.

[0026] As shown in Fig. Figure 3 shows that the edges of the side wall 300 each have a reinforcing section 310 formed by double bending, wherein the reinforcing section 310 is perpendicular to the sheet metal surface of the side wall 300 and the reinforcing section 310 together with the sheet metal surface forms a U-shaped structure, thereby forming a bending structure to increase the structural strength of the side wall 300; the reinforcing section 310 extends along the edge of the side wall 300 and serves for fitting and positioning when connecting with other components.

[0027] As in the Fig. 1, Fig. 2 and Fig. As shown in Figure 4, the sheet metal waste container further comprises top beams 500, first connecting plug elements 1 and second connecting plug elements 2.

[0028] Specifically, the top beams 500, the first connecting plug elements 1 and the second connecting plug elements 2 are also all manufactured using sheet metal processing methods.

[0029] As in the Fig. 1 and Fig. As shown in Figure 2, the reinforcing sections 310 on both sides of the side wall 300 are each connected to a top beam 500; in detail, the longitudinal direction of the top beam 500 is perpendicular to the sheet metal surface of the side wall 300. The top beam 500 on the rear side is rotatably connected to the cover 200, and the top surface of the top beam 500 and the top surface of the side wall 300 are directly opposite the cover 200, so that the cover 200 is supported and limited.

[0030] As in Fig. As shown in Figure 4, the top beam 500 forms a rectangular hollow box structure opening in a horizontal direction, and the opening direction of the top beam 500 is oriented towards the inside of the sheet metal waste container; specifically, the top beam 500 is formed by a plate section 510 and four folded plates 520, which are arranged perpendicular to the plate section 510 and together enclose a cavity; the top beam 500 is also manufactured using a sheet metal fabrication process, with gaps present between each of the four folded plates 520 due to the manufacturing process. The folded plates 520 of the top beam 500 perform the main function of connection and support, with each group of adjacent folded plates 520 being rigidly connected to the reinforcing section 310 of the side wall 300 and to the hinge structure of the lid 200.

[0031] As in the Fig. 5 and Fig. As shown in Figure 6, first connecting plug elements 1 are fixedly arranged inside the top beam 500, that is, the first connecting plug elements 1 can be inserted directly into an interior formed by the top beam 500; and second connecting plug elements 2 are fixedly arranged on the reinforcement section 310, that is, the second connecting plug elements 2 can be inserted directly into a U-shaped structure formed by the reinforcement section and the sheet metal surface of the side wall 300.

[0032] As in Fig. As shown in Figure 7, the first connecting plug element 1 comprises a base plate 11 and two web walls 12, which are formed at least by bending along the upper and lower two sides of the base plate 11, so that the first connecting plug element 1 forms a groove opening; the first connecting plug element 1 is inserted into and fixed in the top beam 500, and the groove opening of the first connecting plug element 1 faces the top beam 500.

[0033] As in Fig. As shown in Figure 8, the second connecting plug element 2 comprises a base plate 21 and two web plates 22, which are formed at least by bending along the upper and lower two sides of the base plate 21, so that the second connecting plug element 2 forms a groove opening; the second connecting plug element 2 is inserted into and fixed in the reinforcement section 310 of the side wall 300, and the groove opening of the second connecting plug element 2 faces the side wall 300; second connecting plug elements 2 are fixedly arranged at positions near the two ends of the reinforcement section 310 on the upper side edge of the side wall 300.

[0034] This is how it is, as in the Fig. As shown in Figures 7 to 9, the base plate 11 of the first connecting plug element 1 is connected to the base plate 21 of the second connecting plug element 2 via an L-shaped adapter plate 3. Specifically, the L-shaped adapter plate 3 comprises, as shown in Fig. Figure 9 shows two plate bodies that are perpendicular to each other, one plate body being rigidly connected to the base plate 11 of the first connecting plug element 1 and the other plate body being rigidly connected to the base plate 21 of the second connecting plug element 2. The L-shaped adapter plate 3 can be in direct contact with the base plate 21 of the second connecting plug element 2 or can be rigidly connected to the base plate 21 of the second connecting plug element 2 indirectly via the reinforcing section 310 of the side wall 300.

[0035] In this way, the box-shaped structures of the first connecting plug element 1 and the second connecting plug element 2, via the L-shaped adapter plate 3, stably support the connection area between the side wall 300 and the top support 500. This increases the overall structural stiffness when the side wall 300 and the top support 500 interact and reinforces their combined support capacity for the lid 200. Simultaneously, it effectively prevents loosening and deformation in the connection area during long-term use. Assembly is simple, manufacturing is quick, and costs are low, thus overcoming the disadvantages of insufficient strength at the corner joints of a sheet metal waste container, which leads to slight loosening and low load-bearing capacity.

[0036] As an optional embodiment of the structure of the first connecting plug element 1, the first connecting plug element 1 further comprises two web walls 12 formed by bending along the left and right sides of the base plate 11, wherein the combination of four web walls 12 and the base plate 11 causes the first connecting plug element 1 to form a laterally open box-shaped structure.

[0037] As in Fig. As shown in Figure 7, the first connecting plug element 1, in a preferred embodiment of its structure, has a U-shaped structure overall, i.e., the number of web walls 12 is only two, and the two web walls 12 are arranged on the upper and lower, opposite side edges of the base plate 11; compared to the above optional embodiment of the structure of the first connecting plug element 1, this design is lighter and more cost-effective.

[0038] Optionally, the first connecting plug element 1 can also have three web walls 12.

[0039] As an optional embodiment of the structure of the second connecting plug element 2, the second connecting plug element 2 has an overall U-shaped structure, that is, the number of multiwall sheets 22 is only two, and the two multiwall sheets 22 are arranged on the upper and lower, opposite side edges of the base plate 21.

[0040] As in Fig. As shown in Figure 8, the second connecting plug element 2, in a preferred embodiment of its structure, forms a horizontally opening rectangular hollow box structure, specifically enclosed by a base plate 21 and four web plates 22 arranged perpendicular to the base plate 21. The opening direction of the second connecting plug element 2 faces the side wall 300. Since the main body of the side wall 300 is a relatively large plate and therefore requires higher support strength, the box-shaped second connecting plug element 2 can provide a more uniform stress distribution for the connection area of ​​the side wall 300 and significantly increase the local bending and shear strength; compared to the above optional embodiment of the structure of the second connecting plug element 2, this structure exhibits better performance under long-term loading.

[0041] Optionally, the second connecting plug element 2 can also have three multiwall sheets 22.

[0042] Preferred are, as in the Fig. 5 and Fig. As shown in Figure 6, the top and bottom of the first connecting plug element 1 are firmly connected to the top beam 500, so that the top and bottom of the first connecting plug element 1 each bear against the upper and lower two sides of the top beam 500, thereby counteracting the deformation tendency of the top beam 500 in the vertical direction and further increasing the connection stability.

[0043] It is preferred, as in the Fig. 5 and Fig. Figure 6 shows the top of the second connecting plug element 2 firmly connected to the reinforcing section 310 on the upper side edge of the side wall 300, and an upper corner of the second connecting plug element 2 is aligned flush with an upper corner of the side wall 300; this creates a stable and reliable corner positioning relationship between the second connecting plug element 2 and the side wall 300, so that the second connecting plug element 2 can not only be positioned precisely during assembly, but the torsional stiffness of the entire frame is also increased.

[0044] Specifically implemented, as in the Fig. 5 and Fig. 6 shown, at the position where the adapter plate 3 is connected to the reinforcement section 310, a bolt successively connects the adapter plate 3, the reinforcement section 310 and the second connecting plug element 2, thereby creating a further secure connection.

[0045] Specifically, as in the Fig. 5 and Fig. As shown in Figure 6, the second connecting plug element 2 extends beyond the reinforcement section 310, thereby further increasing the overlap area of ​​the second connecting plug element 2 on the sheet metal surface of the side wall 300 in order to further increase the strength of the side wall 300.

[0046] Specifically, as in Fig. Figure 6 shows the sheet metal waste container further comprising a damped telescopic compression strut 600; the damped telescopic compression strut 600 can be a hydraulic strut or a cylinder and is designed to provide a damping buffer effect during the opening and closing of the lid 200 in order to effectively reduce the lowering speed of the lid 200 and to prevent noise from being generated by impact or damage to the structure.

[0047] It is preferred, as in the Fig. 1 and Fig. Figure 5 shows a reinforcing rib 210 firmly connected to the underside of the cover 200; one end of the damped telescopic compression strut 600 is pivotally connected to the reinforcing rib 210, and the other end of the damped telescopic compression strut 600 is pivotally connected to a region of the second connecting plug element 2 that projects beyond the reinforcing section 310, so that the second connecting plug element 2 acts as a stable connecting base to support the damped telescopic compression strut 600; compared to an embodiment in which the damped telescopic compression strut 600 is attached directly to the side wall 300, this structure is more stable and effectively distributes the stress concentration acting on the side wall 300 during the operation of the damped telescopic compression strut 600.

[0048] Specifically, as in the Fig. 1, Fig. 9 and Fig. Figure 10 shows a sheet metal waste container with several receiving compartments designed to hold multiple waste bins, with adjacent receiving compartments separated from each other by a partition frame 700; wherein the multiple receiving compartments are two or more receiving compartments. Accordingly, if the sheet metal waste container forms only one receiving compartment, the partition frame 700 is not provided.

[0049] As in Fig. As shown in Figure 10, four sides of the partition frame 700 are assembled, and an upper side edge of the partition frame 700 is an upper partition beam 710; the upper partition beam 710 forms a groove-shaped structure with a downward-facing opening.

[0050] More precisely, the 700 partition frame is also manufactured using sheet metal processing.

[0051] Preferably includes, as in Fig. Figure 12 shows the sheet metal waste container further comprising third connecting plug elements 1a, which correspond in their structure to the first connecting plug element 1, wherein the third connecting plug element 1a is inserted into and fixed in the top beam 500, and wherein the groove opening of the third connecting plug element 1a also faces the top beam 500; wherein the first connecting plug element 1 and the third connecting plug element 1a are each arranged on two sides of the top beam 500; wherein the third connecting plug element 1a is firmly connected to a side surface of the upper separating beam 710 via an L-shaped adapter plate 3.

[0052] This is how it is, as in Fig. Figure 12 shows the third connecting plug element 1a being firmly connected to a side surface of the upper separating beam 710 via an L-shaped adapter plate 3. This design can also effectively increase the connection strength between the separating frame 700 and the top support 500, thus increasing the structural stability of each receiving compartment in a sheet metal waste container with multiple receiving compartments.

[0053] One preferred embodiment comprises, as shown in Fig. Figure 13 shows the sheet metal waste container reinforcement units 800, which are arranged on the underside of the sheet metal waste container, wherein the reinforcement unit 800 is an X-shaped structure and is formed by two reinforcing struts 810 which are rigidly connected to the bottom of the container in a diagonal direction.

[0054] Specifically, as in Fig. Figure 13 shows that the two reinforcing struts 810 are fixed at their intersection point by welding or a bolted connection, thereby further increasing the structural integrity.

[0055] As in Fig. As shown in Figure 13, the X-shaped reinforcement unit 800 can effectively counteract lateral displacement of the lower area of ​​the container walls due to external force and increase the strength of the lower area of ​​the waste container.

[0056] Specifically, as in Fig. Figure 13 shows a reinforcement unit 800 arranged accordingly on the floor of each receiving compartment in the sheet metal waste container. Each reinforcement unit 800 independently supports the floor of the corresponding receiving compartment, thus ensuring that each receiving compartment receives independent and sufficient structural support.

[0057] As a specific embodiment, the sheet metal waste container is a structure with a single receiving space; specifically, the two sides of the bottom of this single receiving space are mainly two side walls 300, wherein the two reinforcing struts 810 are arranged inside in an X-shape and their two ends are each firmly connected to side walls 300 of the container.

[0058] As one specific embodiment, as in Fig. Figure 13 shows the sheet metal waste container divided by a partition frame 700 into two receiving compartments; specifically, the two sides of the bottom of each receiving compartment are each the partition frame 700 and a side wall 300, with a reinforcement unit 800 arranged on the bottom of each receiving compartment; wherein in each reinforcement unit 800 one end of a reinforcement strut 810 is attached to the side wall 300 and the other end is attached to the partition frame 700.

[0059] In one specific embodiment, the sheet metal waste container forms at least three receiving compartments by means of the partition frame 700; specifically, in the receiving compartments on both sides, the two sides of the base are each the partition frame 700 and a side wall 300, while in the receiving compartment arranged in the middle, the two sides of the base are each the partition frame 700. A reinforcement unit 800 is arranged on the base of each receiving compartment; in the reinforcement units 800 in the receiving compartments on both sides, one end of each reinforcement strut 810 is attached to the side wall 300 and the other end is attached to an adjacent partition frame 700; while in the reinforcement unit 800 arranged in a central area, the two ends of each reinforcement strut 810 are each attached to opposite partition frames 700.

[0060] Preferably, the connection types between the components in this application, whether "connecting," "permanent connection," or "removable connection," can be implemented using a threaded connection to facilitate transport and assembly by the user. Specifically, the threaded connection can include screws / bolts, nuts, washers, etc. This structure is particularly suitable for application requirements in urban cleaning and waste disposal scenarios with frequent loading and unloading, as well as complex transport environments, and increases overall practicality and reliability.

[0061] In summary, in the sheet metal waste container of this application, the connection areas between the side walls 300, the top beams 500 and the separating frame 700 are comprehensively reinforced by first connecting plug elements 1, second connecting plug elements 2, third connecting plug elements 1a and reinforcement units 800, so that the entire container structure remains stable and does not deform even under external impacts or long-term use, with each receiving space being stable and robust, thereby effectively extending the service life of the product.
