Detailed Implementation

[0032] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0033] The following is for reference. Figures 1-12 This invention describes a plastic drawer and a locker according to embodiments of the present invention.

[0034] like Figures 1-6 As shown, the plastic drawer 100 includes a plastic decorative shell 10 and a plastic drawer body 20. The plastic decorative shell 10 covers the front end of the plastic drawer body 20. The plastic drawer 100 is integrally formed. The plastic drawer body 20 includes multiple side panels 201 and a bottom panel 202. The bottom panel 202 is connected to the multiple side panels 201. The bottom panel 202 and the multiple side panels 201 enclose a receiving space. The lower ends of the multiple side panels 201 extend downward relative to the bottom panel 202. Slide rails 203 are provided on the side panels 201 located on both sides of the plastic drawer body 20.

[0035] Please see Figure 1 As shown, a plastic decorative shell 10 covers the front end of the plastic drawer body 20, and a handle is provided on the plastic decorative shell 10. The handle can be located at the front end or the top end of the plastic decorative shell 10. In this embodiment, the handle is located at the top end of the plastic decorative shell 10. The handle is formed by opening a groove at the top end of the plastic decorative shell 10, making the front end of the plastic drawer 100 smooth and beautiful.

[0036] The plastic drawer body 20 is molded in one piece. In other words, the plastic drawer body 20 adopts a one-piece injection molding process, which is convenient to manufacture, has good quality stability, and can accommodate various complex plastic drawer structures 100, while reducing costs. Compared with assembled drawers, the plastic drawer body 20 is easier to install, lighter, and easier to pull out.

[0037] Specifically, please refer to Figures 2-5 As shown, the plastic drawer body 20 includes four side panels 201 and a bottom panel 202. The four side panels 201 are connected in sequence and connected to the bottom panel 202 to enclose and form a storage space for placing items.

[0038] The lower ends of the four side panels 201 extend downward relative to the bottom panel 202, forming a support structure. When the plastic drawer body 20 is placed on a flat surface, the bottom panel 202 will not contact the surface, but the side panels 201 will provide support. This can prevent friction damage to the bottom panel 202 and improve the overall appearance quality of the plastic drawer 100.

[0039] Furthermore, slide rails 203 are provided on the outer side of the side panels 201 on both sides of the plastic drawer body 20 to adapt to the external sliding structure, thereby enabling the plastic drawer 100 to be pulled out in the front-back direction.

[0040] According to the embodiment of this utility model, the plastic drawer 100 adopts an integrated injection molding process for the plastic drawer body 20, which is convenient to manufacture, has good quality stability, and can accommodate various complex structures of the plastic drawer 100 while reducing costs. Compared with assembled drawers, the plastic drawer body 20 is easier to install, lighter, and easier to pull out. Furthermore, by extending the lower ends of the four side panels 201 downward relative to the bottom panel 202, the lower ends of the four side panels 201 form a support structure. When the plastic drawer body 20 is placed on a flat surface, the bottom panel 202 will not contact the surface; instead, the side panels 201 provide support. This prevents friction damage to the bottom panel 202 and improves the overall appearance quality of the plastic drawer 100.

[0041] According to some embodiments of the present invention, the slide rail portion 203 includes: a first plate portion 2031 and a second plate portion 2032. The first plate portion 2031 is connected to the lower end of the side plate portion 201 and extends outward relative to the side plate portion 201. The second plate portion 2032 is connected to the side of the first plate portion 2031 away from the side plate portion 201. The second plate portion 2032 is bent downward relative to the first plate portion 2031 and forms a sliding space with the first plate portion 2031.

[0042] Please see Figure 5 and Figure 6 As shown, the first panel 2031 is connected to the lower end of the side panels 201 located on both sides of the plastic drawer body 20. The first panel 2031 extends horizontally outward, and the second panel 2032 is bent downward, so that the first panel 2031 and the second panel 2032 form an approximately right angle. That is, a sliding space is formed at the bottom of the slide rail 203, allowing the slide rail 203 to slide on the guide rail 210 of the cabinet body 200, thereby realizing the pulling out of the plastic drawer 100. Furthermore, the simple structure of the slide rail 203 makes the injection mold easy to manufacture.

[0043] According to some embodiments of the present invention, the rear end of the slide rail 203 is inclined upward and backward to form a limiting part 204, which is used to limit the forward stroke of the plastic drawer 100.

[0044] Please see Figures 2-6 As shown, the rear end of the slide rail 203 is inclined upwards and backwards to form a limiting part 204. That is, the limiting part 204 can serve as the extreme position for the plastic drawer 100 to be pulled forward. The limiting part 204 is engaged with the limiting engagement part 220 of the cabinet body 200 to prevent the plastic drawer 100 from detaching from the cabinet body 200. Specifically, the first plate part 2031 of the slide rail 203 is inclined upwards and backwards to form the limiting part 204, while the limiting engagement part 220 of the cabinet body 200 can be set at a relatively forward position inside the cabinet body 200 to ensure the maximum travel range of the plastic drawer 100.

[0045] According to some embodiments of the present invention, a support portion 205 is provided at the lower end of the side panel portion 201 located on both sides of the plastic drawer body 20. The support portion 205 extends downward and then bends outward relative to the lower end of the side panel portion 201.

[0046] Please see Figure 5 and Figure 6 As shown, the lower end of the side panel 201 on both sides of the plastic drawer body 20 is provided with a support 205. The support 205 extends downward and then bends outward to form an "L-shaped structure" to support the guide rail 210 of the cabinet 200, so that it can slide and cooperate with the slide rail 203, and at the same time, it can provide further stable support for the sliding part.

[0047] According to some embodiments of the present invention, the connection between the side panel portion 201 (excluding the side panel portion 201 located at the front end of the plastic drawer body 20) and the bottom plate portion 202 is made by a rounded transition connection; and / or, the connection between the side panel portions 201 (excluding the side panel portion 201 located at the front end of the plastic drawer body 20) and the other side panel portions 201 is made by a rounded transition connection.

[0048] Please see Figures 1-4As shown, the connection between the side panel 201 at the rear end of the plastic drawer body 20 and the bottom panel 202 on both sides of the plastic drawer body 20 uses a rounded transition. Similarly, the connection between the three side panels 201 also uses a rounded transition. This rounded transition effectively disperses stress, preventing excessive stress concentration at a single point, thereby improving the overall strength and durability of the structure. Furthermore, rounded transitions are smoother and more natural than right-angle or sharp-angle connections, enhancing the product's appeal. Simultaneously, rounded transitions eliminate dead corners, making cleaning easier. Additionally, rounded transitions reduce the risk of injury from sharp edges, providing a safer user experience.

[0049] According to some embodiments of the present invention, the plastic drawer body 20 further includes: a plurality of reinforcing ribs 206, the plurality of reinforcing ribs 206 being spaced apart along the length direction and / or width direction of the bottom plate portion 202, and the two ends of the reinforcing ribs 206 being respectively connected to the inner side surface of the side plate portion 201.

[0050] like Figure 5 and Figure 6 As shown, a plurality of reinforcing ribs 206 are provided on the bottom end face of the base plate 202, spaced apart along its length and width, and the two ends of the reinforcing ribs 206 are respectively connected to the inner side surface of the corresponding side plate 201. This arrangement can enhance the structural strength and rigidity of the base plate 202, thereby enabling it to bear sufficient weight of the items.

[0051] According to some embodiments of the present invention, the side panel portion 201 located at the front end of the plastic drawer body 20 extends beyond the two side panel portions 201 connected thereto in the left and right directions.

[0052] In other words, the two sides of the front side panel 201 extend beyond the dimensions between the two side panels 201. Thus, when the plastic drawer 100 is installed in the cabinet 200, the front side panel 201 can cover the sliding fit structure between the slide rail 203 and the cabinet 200. At the same time, it facilitates the fixed connection between the plastic decorative shell 10 and the two sides of the front side panel 201.

[0053] According to a second aspect embodiment of the present invention, a storage cabinet S includes a cabinet body 200 and a plastic drawer 100. The cabinet body 200 has an inner cavity, and at least one plastic drawer 100 is disposed in the inner cavity and divides the inner cavity into at least two storage compartments 300.

[0054] like Figures 7-12 As shown, a plastic drawer 100 is installed inside the cabinet body 200 to divide the inner cavity of the cabinet body 200 into two storage chambers 300, thereby forming a double-layer storage cabinet S.

[0055] Of course, more plastic drawers 100 can be added to the cabinet 200 to form a multi-layer storage cabinet S.

[0056] According to some embodiments of the present invention, the cabinet 200 includes: guide rails 210 located on both sides inside the cabinet 200, the guide rails 210 and the slide rail 203 are guided and cooperated, and the front end of the guide rails 210 is provided with a limiting cooperation part 220 for limiting the forward stroke of the plastic drawer 100.

[0057] With this configuration, the limiting part 204 at the rear end of the slide rail 203 and the limiting engagement part 220 at the front end of the guide rail 210 can restrict the pull-out stroke of the plastic drawer 100 and limit the plastic drawer 100 from leaving the cabinet 200.

[0058] According to some embodiments of the present invention, the cabinet 200 further includes: a constraint portion 230 located on both sides inside the cabinet 200. The constraint portion 230 is located above the guide rail 210 and is in clearance fit with the upper end of the plastic drawer body 20 to restrict the plastic drawer 100 from moving upward.

[0059] With this configuration, the constraint part 230 is fitted with the upper end of the plastic drawer body 20 with a clearance, which can restrict the plastic drawer 100 from moving upward when it is pulled forward or moved backward.

[0060] According to some embodiments of the present invention, the cabinet 200 includes: a door panel 240, a cover plate, a bottom plate 250, and a plurality of side plates 260.
