Description

Technical Field

[0001] This application relates to the field of item storage technology, and in particular to a locker. Background Technology

[0002] Lockers are widely used in offices, government agencies, factories, and other settings for organizing and storing various types of documents, tools, and other items. Currently, office lockers typically consist of a main frame and several drawers, with the drawers containing various items and small objects.

[0003] In traditional techniques, the main frame of a locker is made of multiple iron plates connected by spot welding. If the welding process is not handled properly, weld seams and protrusions or depressions formed by solder will appear between adjacent iron plates, especially at the joints between the bottom and side plates. When manually moving the locker, since the joints between the side and bottom walls are usually supported by both hands, these protrusions or depressions can easily cut hands and scratch the items stored inside the locker. Utility Model Content

[0004] Therefore, it is necessary to provide a storage cabinet that is easy to move and less likely to cut hands or scratch items, in order to address the aforementioned problems of existing storage cabinets made of welded iron plates.

[0005] According to one aspect of this application, a locker is provided, comprising:

[0006] The main frame includes a base plate and two outer side plates. The two outer side plates are integrally connected to the base plate on opposite sides along a first horizontal direction, so that the two outer side plates are arranged opposite each other in the first horizontal direction.

[0007] The back panel is connected to the edges of the corresponding outer panels on opposite sides along the first horizontal direction, and / or the bottom edge of the back panel is connected to the edge of the bottom plate along the second horizontal direction, which is perpendicular to the first horizontal direction. The bottom plate, the two outer panels, and the back panel together form a first storage space.

[0008] In one embodiment, the storage cabinet further includes a top plate, which is connected to the top of the corresponding outer plate on opposite sides along the first horizontal direction, so that the top plate and the bottom plate are vertically opposite to each other and close the upper opening of the first storage space.

[0009] In one embodiment, the locker further includes a drawer that is slidably connected to the two outer panels along the second horizontal direction, such that the drawer can be accommodated within the first storage space or at least partially extend from an opening in the first storage space away from the back panel to the outside of the first storage space.

[0010] And / or, the locker further includes a door movably connected to at least one of the base plate, the outer side plate, or the top plate, such that the door can open or close an opening in the first storage space away from the back plate.

[0011] In one embodiment, the outer panel includes an outer panel body and a cabinet panel that are spaced apart from each other along the first horizontal direction. Each cabinet panel is connected to the side of the corresponding outer panel body facing the first storage space, and each cabinet panel is provided with a guide rail on the side away from the outer panel body. The drawer is slidably connected to the guide rail, so that the drawer is slidably connected to the cabinet panel through the guide rail.

[0012] In one embodiment, each of the outer panel bodies has a first bending portion and a second bending portion at opposite ends along the second horizontal direction, and each of the cabinet panels has a third bending portion and a fourth bending portion at opposite ends along the second horizontal direction, respectively, that bends toward the outer panel.

[0013] The first bend is attached to the third bend, the second bend is attached to the back panel, and the fourth bend is also attached to the back panel or connected to the outer side panel body, so that a buffer space is formed between the outer side panel body and the cabinet panel.

[0014] In one embodiment, the top plate includes a top plate body and a plurality of top plate enclosures. The top plate enclosures bend and extend from the edge of the top plate body in a direction away from the first storage space. At least a portion of the top plate enclosures are attached to the outer side plate, and all the top plate enclosures and the top plate body form a first open space.

[0015] In one embodiment, the locker further includes a flap that is movable relative to the top panel to expose or close the top panel.

[0016] In one embodiment, the flap includes a flap body, two first flap barriers and two second flap barriers. The two first flap barriers are bent from opposite edges of the flap body and spaced apart from each other along the first horizontal direction. The two second flap barriers are bent from other opposite edges of the flap body and spaced apart from each other along the second horizontal direction. The flap body, all the first flap barriers and all the second flap barriers form a second open space.

[0017] When the flip cover is closed on the top plate, the opening of the second open space faces the top plate.

[0018] In one embodiment, the first flap enclosure is integrally connected to the flap body, and / or the second flap enclosure is integrally connected to the flap body.

[0019] In one embodiment, the connection point between the first flap enclosure and the flap body and / or the connection point between the second flap enclosure and the flap body has a rounded corner.

[0020] In one embodiment, the top edge of the outer panel and / or the top panel enclosure is connected to a flange; wherein the flange connected to the outer panel is parallel to the outer panel and located on the side of the outer panel facing the inside of the storage cabinet, and the flange connected to the top panel enclosure is parallel to the top panel enclosure and located on the side of the top panel enclosure facing the inside of the storage cabinet;

[0021] When the flap is closed on the top plate, the flap covers all the flanges inside the flap.

[0022] In one embodiment, the outer side plate has a rounded corner at the connection point with the bottom plate.

[0023] In one embodiment, the locker further includes a plurality of feet connected to the base plate, the feet being extendable and retractable relative to the base plate, so that the vertical dimensions of the locker are variable.

[0024] The aforementioned locker, by bending a single sheet metal piece to form the base plate and two outer side plates, creates a U-shaped main frame. The base plate and outer side plates are integrally connected, eliminating the need for welding between them. This eliminates weld seams and solder bumps or dents at the connection points, preventing cuts to hands and scratches to items inside during manual handling. This improves the user experience and facilitates the widespread adoption of lockers in more scenarios. Attached Figure Description

[0049] One embodiment of this application provides a locker for storing and managing various documents and items.

[0050] The following description uses a small office locker (e.g., a sheet metal locker with dimensions ranging from 150-450mm in length, 100-300mm in width, and 100-500mm in height) welded from multiple metal sheets as an example to illustrate the structure of the locker in this application. This embodiment is only used as an example and does not limit the technical scope of this application. It is understood that in other embodiments, the locker in this application is not limited to a small office locker, but can also be a locker of any size and used in any scenario, and is not limited here.

[0051] See Figures 1 to 3 , Figure 1 This paper shows a schematic diagram of the appearance of the locker 10 in one embodiment of the present application. Figure 2 and Figure 3 An exploded view of the locker 10 is shown. An embodiment of the locker 10 provided in this application includes a main frame 100, a back panel 200, a top panel 300, and drawers 400. The main frame 100 includes a bottom panel 110 and two outer side panels 120. At least one end of each of the two outer side panels 120 is integrally connected to the bottom panel 110 and is spaced apart from each other along a first horizontal direction (X direction shown in the figure). The two outer side panels 120 are connected to the two end edges of the bottom panel 110 in the first horizontal direction, such that the two outer side panels 120 are located on opposite sides of the main frame 100 along the first horizontal direction. The top panel 300 is parallel to the bottom panel 110 in the vertical direction (Z direction shown in the figure), and the top panel 300 is connected to the two outer side panels 120 away from the bottom panel 110. The bottom plate 110 is at one end; the back plate 200 is connected to the outer side plate 120 at opposite ends along the first horizontal direction; the bottom plate 110, the outer side plate 120, the back plate 200 and the top plate 300 together form a first storage space 101; the drawer 400 is movably accommodated in the first storage space 101 and slidably connected to the outer side plate 120, so that the movement of the drawer 400 in the first horizontal direction is restricted, and the drawer 400 can slide along a second horizontal direction perpendicular to the first horizontal direction (Y direction shown in the figure) to be at least partially exposed from the opening on the side away from the back plate 200 in the first storage space 101 and in an open state or fully accommodated in the first storage space 101 and in a closed state.

[0052] Figure 2 In one embodiment, the outer panel 120 has a double-layer structure, which includes an outer panel body 121 and a cabinet panel 122 that are spaced apart from each other along a first horizontal direction. Each cabinet panel 122 is connected to the side of the corresponding outer panel body 121 facing the first storage space 101, so that a buffer space 102 is formed between the outer panel body 121 and the cabinet panel 122, and the drawer 400 is slidably connected to the cabinet panel 122.

[0053] The outer side panel 121 and the bottom plate 110 of the main frame 100 are formed by bending a single sheet metal piece, so that the two outer side panel bodies 121 are integrally connected to the bottom plate 110, thus giving the main frame 100 a U-shape. In this way, by integrally connecting the bottom plate 110 to the two outer side panel bodies 121, no welding connection is required between the bottom plate 110 and the outer side panel bodies 121. Therefore, there are no weld seams or protrusions or depressions left by solder at the connection point between the bottom plate 110 and the outer side panel bodies 121. This prevents hands from being cut when manually handling the storage cabinet 10, and prevents items inside the storage cabinet 10 from being scratched, improving the user experience.

[0054] It is understood that the outer side plate 121 can also be connected to the base plate 110 by welding or other methods such as screwing, riveting, or welding, and this is not limited here. It is also understood that in other embodiments, the outer side plate 120 can also be a single-layer structure, and this is not limited here.

[0055] Preferably, based on the above embodiments, the connection position between the base plate 110 and the outer side plate body 121 also has an arc-shaped rounded corner, which can further facilitate handling and further prevent hands from being cut by the sharp corners between the base plate 110 and the outer side plate body 121.

[0056] When it is necessary to place items, drawer 400 can be pulled out so that at least part of drawer 400 is exposed in the first storage space 101. After placing items into drawer 400, drawer 400 can be pushed back into the first storage space 101 to complete the storage of items.

[0057] It is easy to see that by setting the outer side panel 120 of the storage cabinet 10 as a double-layer structure including the outer side panel body 121 and the cabinet panel 122, a buffer space 102 is formed between the outer side panel body 121 and the cabinet panel 122. The drawer 400 is slidably connected to the cabinet panel 122, so that the drawer 400 directly applies force to the cabinet panel 122. This reduces the force on the outer side panel body 121, thus better protecting the outer side panel body 121 and improving the durability of the storage cabinet 10. Of course, each cabinet panel 122 can also abut against the bottom plate 110 and the top plate 300 on both sides along the vertical direction to improve the stability of the cabinet panel 122.

[0058] In some embodiments, the drawer 400 and the cabinet panel 122 are slidably connected by a guide rail 130. For example, the guide rail 130 may consist of two tracks, one male and one female, that slide against each other. One track is mounted on the cabinet panel 122, and the other track is mounted on the drawer 400. The sliding of the two tracks facilitates the sliding of the drawer 400 and reduces frictional resistance during sliding. However, this design requires the additional manufacture or purchase of the guide rail 130, which complicates the manufacturing process of the storage cabinet 10 and increases its manufacturing cost.

[0059] To address the aforementioned issues, in some preferred embodiments, the guide rail 130 is mounted solely on the cabinet panel 122. Specifically, in conjunction with... Figure 3 and Figure 4 As shown, the guide rail 130 includes a first guide rail 131 and a second guide rail 132. Both the first guide rail 131 and the second guide rail 132 are connected to the cabinet panel 122 and extend along the second horizontal direction respectively. The drawer 400 is slidably connected to the first guide rail 131 and the second guide rail 132 so that it can slide along the second horizontal direction under the guidance of the first guide rail 131 and the second guide rail 132. Moreover, the movement of the drawer 400 in the vertical direction is also restricted by the limiting of the first guide rail 131 and the second guide rail 132.

[0060] Preferably, in one embodiment, the first guide rail 131 and the second guide rail 132 are integrally connected to the cabinet panel 122. Specifically, the first guide rail 131 is bent from the cabinet panel 122 toward the first storage space 101 to form a first cutting groove 122a on the cabinet panel 122, and the second guide rail 132 is also bent from the cabinet panel 122 toward the first storage space 101 to form a second cutting groove 122b on the cabinet panel 122.

[0061] exist Figure 4 In the embodiment, the first guide rail 131 is flat and perpendicular to the cabinet panel 122. The second guide rail 132 is located above the first guide rail 131, is also flat and perpendicular to the cabinet panel 122, so that the first guide rail 131 and the second guide rail 132 are parallel to each other. The drawer 400 is located between the first guide rail 131 and the second guide rail 132, and the two ends of the drawer 400 along the vertical direction are slidably attached to the first guide rail 131 and the second guide rail 132, respectively, so as to be slidably connected to the first guide rail 131 and the second guide rail 132.

[0062] Thus, in this embodiment, the first guide rail 131 restricts the drawer 400's movement in the vertically downward direction, and the second guide rail 132 restricts the drawer 400's movement in the vertically upward direction. This allows the drawer 400 to be held in place by the first and second guide rails 131 and 132 during sliding, ensuring stability and preventing it from tilting upwards. More importantly, the first and second guide rails 131 and 132 are structurally simple, requiring only a bend from the cabinet panel 122 towards the first storage space 101. No modifications to the drawer 400's structure are needed to allow the drawer 400 to slide smoothly against the second and first guide rails 132 and 131 respectively along its vertical upper and lower edges, enabling simultaneous sliding connection with both guide rails 131 and 132. This not only achieves the same technical effect as existing male and female two-rail systems but also saves manufacturing costs.

[0063] Optionally, the extension length of the second guide rail 132 along the second horizontal direction can be equal to or less than the extension length of the first guide rail 131 along the second horizontal direction. When the extension length of the second guide rail 132 along the second horizontal direction is less than the extension length of the first guide rail 131 along the second horizontal direction, the second guide rail 132 is positioned near the opening of the first storage space 101 along the second horizontal direction on the cabinet panel 122, which is not limited here.

[0064] See Figure 5 and Figure 6 , Figure 5 and Figure 6 A schematic diagram of the cabinet panel 122 according to another embodiment is shown. In this embodiment, the first guide rail 131 and the second guide rail 132 are also integrally connected to the cabinet panel 122 and extend along the second horizontal direction, so that the first guide rail 131 and the second guide rail 132 are parallel to each other. Moreover, the first guide rail 131 and the second guide rail 132 are both formed by bending from the cabinet panel 122 toward the first storage space 101.

[0065] But with Figure 3 and Figure 4 The cabinet panel 122 shown differs in that the first guide rail 131 is located above the second guide rail 132, and the end of the first guide rail 131 away from the cabinet panel 122 is bent upwards to form a limiting groove 130a extending along a second horizontal direction. A portion of the drawer 400 is slidably limited within the limiting groove 130a to be slidably connected to the cabinet panel 122. Specifically, the drawer 400 includes a drawer body 410 and a limiting portion 420. The limiting portion 420 is connected to the side of the drawer body 410 near the cabinet panel 122 and is slidably limited within the limiting groove 130a. More specifically, as shown... Figure 7 As shown, the first guide rail 131 is U-shaped, including an integrally connected first bent portion 1311 and second bent portion 1312. The first bent portion 1311 is connected to the cabinet panel 122 and bends towards one side of the cabinet panel 122. Optionally, the first bent portion 1311 is perpendicular to the cabinet panel 122. The second bent portion 1312 bends upward from the edge of the first bent portion 1311 away from the cabinet panel 122. The limiting groove 130a is formed by the first bent portion 1311, the second bent portion 1312, and one side of the cabinet panel 122. Correspondingly, as... Figure 8 As shown, the limiting part 420 is an inverted U-shape, which is formed by turning outward from the top edge of the drawer body 410 in a direction away from the drawer body 410 (i.e., in a direction close to the cabinet panel 122) and bending downward in the vertical direction.

[0066] It is understood that the limiting groove 130a is not limited to being formed by bending, and the limiting part 420 is not limited to being an inverted U-shape. As long as it can be limited in the limiting groove 130a after being bent from the top edge of the drawer body 410 toward the cabinet panel 122, the limiting part 420 can also be installed on the drawer body 410 as a separate part, or it can be integrally connected to the drawer body 410 by sheet metal bending. There are no limitations here.

[0067] Thus, by designing the first guide rail 131 as a U-shape, the drawer 400 can be hung on the first guide rail 131 and slide in cooperation with it. This allows the first guide rail 131 to not only restrict the vertical downward movement of the drawer 400 but also to provide better guidance, achieving the same function as in the previous embodiment. Moreover, the structure of the drawer 400 does not require significant modifications; it only needs to be bent to form a limiting part 420 that can be confined in the limiting groove 130a so that the drawer 400 can be hung on the first guide rail 131.

[0068] It should be noted that, unlike the previous embodiment, in this embodiment, the second guide rail 132 is located below the first guide rail 131. Thus, when the limiting part 420 of the drawer 400 is confined within the limiting groove 130a of the first guide rail 131, the second guide rail 132 can support the drawer 400, restricting its movement in the vertically downward direction and preventing excessive sagging when the drawer 400 slides along the second horizontal direction. This better secures the drawer 400 and prevents it from wobbling up and down.

[0069] Similarly, the extension length of the second guide rail 132 along the second horizontal direction can be equal to or less than the extension length of the first guide rail 131 along the second horizontal direction, and there is no limitation in this embodiment.

[0070] Of course, in other embodiments, the first guide rail 131 and the second guide rail 132 are not limited to being formed by bending after slotting on the cabinet panel 122. They can also be connected to the cabinet panel 122 by welding a piece of sheet metal or by screwing, riveting or other means. There is no limitation on this.

[0071] It should be noted that in the above embodiments, only the first guide rail 131 can be provided. However, it is obvious that by providing both the first guide rail 131 and the second guide rail 132, in the first embodiment described above, the drawer 400 will not tilt upwards when sliding; and in the second embodiment described above, the drawer 400 can be supported by the second guide rail 132 when sliding, and will not droop downwards too much. This is obviously the best embodiment.

[0072] Furthermore, in all the above embodiments, when the drawer 400 is pulled out from the first storage space 101, in order to prevent the drawer 400 from falling out, such as... Figure 3 and Figure 4 As shown, the cabinet panel 122 is provided with a blocking structure 140 on one side of the first guide rail 131 along the vertical direction, that is, between the first guide rail 131 and the second guide rail 132. The blocking structure 140 is located near the opening of the storage cabinet 10 along the second horizontal direction. When the drawer 400 is in the pulled-out state, the blocking structure 140 can prevent the drawer 400 from being pulled out further. Specifically, as Figure 3 and Figure 9 As shown, drawer 400 has a locking structure 430 on the side near cabinet panel 122. One of the blocking structure 140 and locking structure 430 has a slot 431. Correspondingly, the other of the blocking structure 140 and locking structure 430 has a stop piece 141. When drawer 400 slides outward from storage cabinet 10 along the second horizontal direction and is in the pulled-out state, the stop piece 141 can be locked in the slot 431, so that the blocking structure 140 and locking structure 430 can be locked together, thereby preventing drawer 400 from being pulled out further and thus preventing drawer 400 from falling.

[0073] Preferably, the vertical dimension of the blocking structure 140 or the snap-fit ​​structure 430 is greater than or equal to one-third of the vertical dimension of the drawer 400. With this arrangement, the vertical dimension of the slot 431 in either the blocking structure 140 or the snap-fit ​​structure 430 is larger, resulting in a larger vertical dimension of the slot 431. Therefore, even if the drawer 400 is pulled outwards and offset by a certain angle, the stop piece 141 can easily insert into the slot 431, thus preventing the drawer 400 from shifting downwards by a certain angle and becoming difficult to lock.

[0074] In the connection structure between the outer side panel body 121 and the cabinet panel 122, combined with Figure 4 , Figure 10 and Figure 11As shown, each outer panel body 121 has a first bent portion 1211 and a second bent portion 1212 at opposite ends along the first horizontal direction, bent towards the cabinet panel 122, through a bending process. Each cabinet panel 122 also has a third bent portion 1221 and a fourth bent portion 1222 at opposite ends along the first horizontal direction, bent towards the outer panel body 121, through a bending process. The first bent portion 1211 is attached to the third bent portion 1221, the second bent portion 1212 is attached to the back panel 200, and the fourth bent portion 1222 is connected to the outer panel body 121, so that a buffer space 102 is formed between the outer panel body 121 and the cabinet panel 122. By forming the buffer space 102, the outer panel body 121 can withstand less force when the drawer 400 slides, thus better protecting the outer panel body 121.

[0075] exist Figure 4 , Figure 10 and Figure 11 In one embodiment, the outer panel body 121 further has a fifth bend 1213, which bends and extends from the edge of the first bend 1211 in a direction parallel to the cabinet panel 122. The cabinet panel 122 also has a sixth bend 1223, which bends and extends from the edge of the fourth bend 1222 in a direction close to the back panel 200. The cabinet panel 122 has a first step plate 1224 and a second step plate 1225 that are parallel to each other by bending. The guide rail 130 is connected to the first step plate 1224. The second step plate 1225 is attached to the fifth bend 1213. The sixth bend 1223 is attached to the portion of the outer panel body 121 excluding the first bend 1211 and the second bend 1212, so that the outer panel body 121 and the cabinet panel 122 can be more firmly fixed.

[0076] It should be noted that the cabinet panel 122 and the outer side panel body 121 are not limited to the embodiment shown in the figure. For example, in another embodiment, the cabinet panel 122 does not have a sixth bend 1223, but is directly attached to the back panel 200 by the fifth bend 1213, or the outer side panel body 121 does not have a fifth bend 1213, and the first step plate 1224 and the second step plate 1225 of the cabinet panel 122 are coplanar. None of the above are limited.

[0077] For the structure of the top plate 300, see [reference]. Figure 3 In some embodiments, the top plate 300 includes a top plate body 310 and a plurality of top plate enclosures 320. The top plate enclosures 320 bend upward from the edge of the top plate body 310 in a direction away from the first storage space 101. At least a portion of the top plate enclosures 320 are attached to the outer side plate body 121. All the top plate enclosures 320 and the top plate body 310 enclose a first open space 301.

[0078] In this way, the welding gun can be used to weld the top plate 300 and the outer side plate body 121 together from outside the first storage space 101, avoiding the welding gun from being inserted into the first storage space 101 and causing welding inconvenience. In addition, the storage cabinet 10 can also be used to place items or store documents in the first open space 301, which is convenient for users.

[0079] In the embodiment shown in the figure, the storage cabinet 10 is quadrilateral when viewed from above, therefore the top panel 300 is also quadrilateral. The top panel enclosure 320 in this embodiment has three pieces: two pieces are welded to an outer panel body 121, and the remaining piece is welded to the back panel 200. Alternatively, there could be two pieces of top panel enclosure 320, each attached to an outer panel body 121, with the back panel 200 abutting against the edge of the top panel body 310; or there could be four pieces of top panel enclosure 320. This is not a limitation.

[0080] Optionally, to better secure the top plate 300, in one embodiment, a seventh bend 330 is connected to one edge of the top plate body 310, combined with... Figure 3 and Figure 4 As shown, three edges of the top panel body 310 are connected to the top panel enclosure 320, and the remaining edge is connected to the seventh bend 330. The seventh bend 330 extends from this edge of the top panel body 310 toward the first storage space 101. The first bends 1211 of the two outer panel bodies 121 are attached to the seventh bend 330, and the top edges of the third bends 1221 of the two cabinet panels 122 abut against the edge of the seventh bend 330. Thus, it can be seen that the third bends 1221 of the two cabinet panels 122 support the seventh bend 330, and the seventh bend 330 is attached to the first bend 1211, thereby providing good support for the top panel 300 as a whole. Even when the first storage space 101 needs to bear heavy items, the top panel 300 can still support it.

[0081] See Figures 12 to 14 In another embodiment of the locker 10, the locker 10 further includes a flip cover 500, which is movable relative to the top panel 300. For example, the flip cover 500 is rotatably connected to the back panel 200 so that the top panel 300 can be exposed or closed. Specifically, in Figure 12 , Figure 13 and Figure 14In one embodiment, the flip cover 500 includes a flip cover body 510, two first flip cover barriers 520, and two second flip cover barriers 530. The two first flip cover barriers 520 are bent from opposite edges of the flip cover body 510 and spaced apart relative to each other along a second horizontal direction. The two second flip cover barriers 530 are bent from the other opposite edges of the flip cover body 510 and spaced apart relative to each other along a first horizontal direction. The flip cover body 510, all the first flip cover barriers 520, and all the second flip cover barriers 530 are... The top plate 300 forms a second open space 501; a second flap 530 is rotatably connected to the back plate 200 via hinges or other parts, so that the flap 500 can rotate about an axis extending in a first horizontal direction. When the flap 500 is closed on the top plate 300, the flap 500 closes the opening of the first open space 301, and the opening of the second open space 501 faces the opening of the first open space 301, and together with the first open space 301, forms a second storage space.

[0082] It is easy to see that by setting the flip cover 500, the items or documents stored in the first open space 301 can be protected, and by forming a second open space 501 in the flip cover 500, the second storage space has a large volume, which can store more items while also protecting them.

[0083] Furthermore, in order for the flip cover 500 to effectively close the first open space 301, such as... Figure 14 and Figure 15 As shown in the embodiment, the upper edges of the two outer panel bodies 121 and the top panel enclosure 320 parallel to the back panel 200 are integrally connected with flanges 1214 by bending. The flanges 1214 connected to the outer panel bodies 121 are parallel to the outer panel bodies 121 and located on the side of the outer panel bodies 121 facing the inside of the storage cabinet 10 (i.e., the side of the outer panel bodies 121 facing the first storage space 101). The flanges 1214 connected to the top panel enclosure 320 are parallel to the top panel enclosure 320 and located on the side of the top panel 300 facing the inside of the storage cabinet 10 (i.e., the side of the top panel enclosure 320 facing the first storage space 101). With this arrangement, when the flip cover 500 is closed on the top plate 300, the flip cover 500 can cover the flange 1214 inside the flip cover 500; preferably, the first flip cover barrier 520 and the second flip cover barrier 530 of the flip cover 500 can respectively fit onto one of the flanges 1214, thus achieving the purpose of better sealing the first open space 301.

[0084] It is understood that all the top panel enclosures 320 of the top panel 300 may be connected with flanges 1214, rather than only the outer panel body 121 being connected with flanges 1214; and in the embodiment where the storage cabinet 10 has a flip cover 500, the top panel 300 may be just a flat plate and may not include the top panel enclosures 320, and there is no particular limitation here.

[0085] Alternatively, the first flap guard 520 is integrally connected with the flap body 510, and preferably, the connection point between the first flap guard 520 and the flap body 510 may also have rounded corners to prevent the user's hand from being cut.

[0086] Of course, it is understandable that the second flap enclosure 530 and the flap body 510 can also be connected as one piece, and the connection position between the second flap 500 and the flap body 510 can also have a rounded corner.

[0087] In addition, as a preferred embodiment, such as Figure 2 As shown, the locker 10 also includes several feet 600 connected to the base plate 110. The feet 600 are telescopic relative to the base plate 110, so that the vertical dimensions of the locker 10 are variable. For example, the feet 600 can be threaded to the base plate 110, and the size of the feet 600 protruding from the base plate 110 can be adjusted by adjusting the depth of the threads screwed into the base plate 110. Alternatively, the feet 600 themselves can be telescopic, so that the overall vertical height of the locker 10 can be adjusted by adjusting the feet 600, thereby meeting the needs of users of different heights.

[0088] It should be noted that in some other embodiments, combined with Figure 16 As shown, the storage cabinet 10 is not limited to having only drawers 400 for storing items; it can also be a structure that includes both drawers 400 and cabinet doors 700. The cabinet doors 700 are arranged opposite to the back panel 200 and are movably connected to at least one of the bottom panel 110, the outer side panel 120, or the top panel 300, so that the cabinet doors 700 can open or close the opening on the side of the first storage space 101 away from the back panel 200. Alternatively, the storage cabinet 10 provided in this application is not limited to having a top panel 300 and a back panel 200; none of the above is limited.

[0089] Therefore, the storage cabinet 10 provided in this application has the following advantages: Firstly, since the outer side panel 121 and the bottom panel 110 are connected as a whole, the main frame 100 is U-shaped. During assembly, the back panel 200 and the cabinet panel 122 are simply placed into the main frame 100, and finally the top panel 300 is placed in for overall welding. Then, the drawer 400 is installed to complete the assembly. Therefore, the structure is simple and easy to assemble. Moreover, it is not easy to cut hands during transportation, which effectively solves the safety problem of metal storage cabinet 10 during transportation.

[0090] On the other hand, by using bending to form a first guide rail 131 and a second guide rail 132 integrally connected to the cabinet panel 122, it is not necessary to manufacture or purchase the guide rail 130 separately for welding or screwing to the cabinet panel 122. This allows the problem of making the drawer 400 slide easily to be solved with fewer parts, fewer processing steps, and less cost. This can improve the production efficiency of the storage cabinet 10, shorten the delivery time of the storage cabinet 10, and help improve the economic benefits of furniture manufacturers.

[0091] 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.

[0092] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
