Install the left iron sliding door 17 and the right glass sliding door 18 on the front side of the top face 5 and the bottom face 6 respectively through the slide rail structure, so that the left iron sliding door 17 and the right glass sliding door 18 can slide relative to each other in the horizontal direction. The processing technology for the left side panel 1, left back panel 2, right back panel 3, right side panel 4, top panel 7, bottom panel 8, large partition 9, half-middle side panel 10, left partition 11, right partition 12, inner lower panel 13, left sliding door 17, and right sliding door 18 can be completed in one go by laser cutting or shearing and punching.

[0032] Specifically, the installation method for this steel sheet metal wardrobe is based on the aforementioned wardrobe structural design and includes the following six steps. This installation method is simple to operate, requires no professional tools, and can be completed by ordinary users, while ensuring the stability of the assembled cabinet structure. Step 1: First, connect the left side panel 1, left back panel 2, right back panel 3, and right side panel 4 using bolts. After completing the connection of the above components, use bolts to connect the top panel 5 and bottom panel 6 to the top and bottom of the left side panel 1 and right side panel 4 respectively. The connection positions of the top panel 5 and bottom panel 6 need to be positioned to ensure a firm connection with the left side panel 1 and right side panel 4. Then, install the top panel 7 and bottom panel 8 on the inside of the top panel 5 and bottom panel 6 respectively. The top panel 7 fits snugly against the top panel 5, and the bottom panel 8 fits snugly against the bottom panel 6, and are fixed using threaded connections. This completes the assembly of the main frame of the wardrobe. The main frame is the foundation of the entire wardrobe; ensuring its firm connection improves the overall structural strength of the wardrobe. The second step is to place the large partition 9 horizontally at the predetermined height inside the cabinet. Both sides of the large partition 9 have snap-fit ​​structures, which are used to connect it to the left side panel 1 and the right side panel 4 respectively. When connecting the snap-fits, ensure that the snap-fit ​​hooks 21 are inserted into the limiting holes of the snap-fit ​​plate 20 and bent to lock, thus securing the large partition 9 firmly. The large partition 9 divides the cabinet interior into two independent storage spaces, facilitating the categorization of items. The third step is to vertically install the semi-middle side panel 10 inside the cabinet. The bottom of the semi-middle side panel 10 has a snap-fit ​​structure, which is used to connect it to the bottom panel 8 or the bottom surface 6, ensuring the semi-middle side panel 10 is vertically fixed. The semi-middle side panel 10 divides the cabinet interior space along the width direction, further refining the storage area and providing support for the subsequent installation of other components. Fourth, install the left partition 11 and right partition 12 onto the left and right sides of the cabinet interior using left and right snap-fit ​​connections. The left partition 11 is snap-fitted to the left side panel 1 and the half-middle side panel 10, and the right partition 12 is snap-fitted to the right side panel 4 and the half-middle side panel 10, forming a vertical divider to further divide the storage space and improve the wardrobe's storage practicality. Fifth, install the inner safe lower panel 13 horizontally at the bottom of the cabinet using left and right snap-fit ​​connections. The inner safe lower panel 13 works in conjunction with the left partition 11 and right partition 12 to form an independent safe space at the bottom of the cabinet for storing valuables. Sixth, install the left iron sliding door 17 and right glass sliding door 18 onto the front of the top panel 5 and bottom panel 6 using a sliding rail structure. The sliding rail structure is located on the inside of the top panel 5 and bottom panel 6, and the sliding doors are compatible with the sliding rails, allowing the left iron sliding door 17 and right glass sliding door 18 to slide relative to each other horizontally, thus opening and closing the wardrobe.In addition, the processing technology of the left side panel 1, left back panel 2, right back panel 3, right side panel 4, top panel 7, bottom panel 8, large partition 9, half middle side panel 10, left partition 11, right partition 12, inner lower panel 13, left sliding door 17 and right sliding door 18 are all laser cutting or shearing punching. Both processing technologies can be completed in one go without secondary processing, which can greatly improve processing efficiency, reduce processing costs, and at the same time ensure the dimensional accuracy and surface flatness of the sheet metal parts, and ensure the compatibility between the parts.

[0033] Between S5 and S6, the following steps are also included: passing the clothes rail 16 through the half-middle side plate 10 and threading it to the left side plate 1; fixing the pivot and the inner retaining vertical face 14 to the inner retaining lower plate 13 and the large partition 9.

[0034] Specifically, between steps five and six of the above installation method, an additional installation step is added. This step is mainly used to install the clothes rod 16 and related internal components, ensuring smooth cooperation between the components and improving the functionality of the wardrobe. The specific steps are as follows: First, pass the clothes rod 16 through the sliding installation structure inside the half-side panel 10. After one end of the clothes rod 16 is inserted into the sliding structure of the half-side panel 10, its extension length can be adjusted according to the actual hanging needs. After adjustment, fix the other end of the clothes rod 16 to the outer wall of the left side panel 1 using a threaded connection. When threading, ensure that it is tightened properly to prevent the clothes rod 16 from shaking. After the clothes rod 16 is installed, the rotating shaft and the inner protective vertical face 14 are fixedly installed between the inner protective lower plate 13 and the large partition 9. The two ends of the rotating shaft are inserted into the connecting holes of the inner protective lower plate 13 and the large partition 9 respectively to ensure that the rotating shaft is firmly installed and can rotate flexibly. The inner protective vertical face 14 is placed vertically between the inner protective lower plate 13 and the large partition 9 and fixed by bolts or buckles to ensure the verticality and stability of the inner protective vertical face 14.

[0035] The snap-fit ​​connection method includes: snap-fit ​​hook 21 and snap-fit ​​plate 20 are fixedly connected to the two parts to be connected respectively, the hook part of snap-fit ​​hook 21 is inserted into the limiting hole inside snap-fit ​​plate 20, and then the hook part of snap-fit ​​hook 21 is bent.

[0036] Specifically, the snap-fit ​​connection method used in this steel sheet metal wardrobe mainly consists of two parts: a snap-fit ​​hook 21 and a snap-fit ​​plate 20. The snap-fit ​​hook 21 and snap-fit ​​plate 20 are fixedly connected to the two parts to be connected by welding or stamping. During fixing, ensure that their positions correspond so that the snap-fit ​​hook 21 can smoothly insert into the limiting hole of the snap-fit ​​plate 20. During installation, first align the two parts to be connected, aligning the hook portion of the snap-fit ​​hook 21 with the limiting hole inside the snap-fit ​​plate 20. Then, insert the hook portion into the limiting hole. After insertion, utilize the bendable and deformable characteristic of the hook portion of the snap-fit ​​hook 21 to bend it to one side, making the hook portion fit tightly against the inner wall of the snap-fit ​​plate 20, achieving locking and fixing, thus firmly connecting the two parts together. This snap-fit ​​connection method is not only simple to operate, requiring no professional tools, but also ensures a strong connection, reduces the use of parts, lowers production costs, and improves the assembly and disassembly efficiency of the wardrobe. It is suitable for large-scale mass production and user self-assembly.

[0037] The rotating shaft and the inner vertical face 14 are equipped with spring pins. The push rod of the spring pin can be inserted into the connecting hole inside the inner lower plate 13 and the large partition 9.

[0038] Specifically, the rotating shaft and the inner retaining wall vertical face 14 are internally equipped with spring pins. These spring pins are made of metal and possess good elasticity and toughness, enabling automatic reset. Their main function is to fix the rotating shaft and the inner retaining wall vertical face 14, ensuring stability after installation and preventing loosening. The spring pin's push rod can freely extend and retract under the action of the spring. The inner retaining wall lower plate 13 and the large partition 9 have connecting holes adapted to the spring pin's push rod. The size of the connecting holes is just large enough to accommodate the insertion of the spring pin's push rod. When installing the rotating shaft and the inner retaining wall vertical face 14, first press the spring pin's push rod to the retracted state. Then, align the rotating shaft and the inner retaining wall vertical face 14 with the connecting holes of the inner retaining wall lower plate 13 and the large partition 9. Release the pressed push rod; the spring pin resets under the action of the spring, and the push rod automatically inserts into the connecting holes of the inner retaining wall lower plate 13 and the large partition 9, achieving rapid fixing of the rotating shaft and the inner retaining wall vertical face 14. This spring pin fixing method is convenient to operate and secure, effectively preventing the pivot and inner door 14 from loosening during use, ensuring that the inner door 15 can rotate flexibly around the pivot, and facilitating subsequent disassembly and maintenance, thus improving the convenience and service life of the wardrobe.
