[0035] The technical scheme in this embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in this embodiment of the present invention. Obviously, the described embodiment is one embodiment of the present invention, not all embodiments of the present invention. Based on this embodiment of the present invention, all other embodiments of the present invention obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 5 The present embodiment provides a hidden shelf support structure for a metal cabinet, comprising a support 1, a mounting seat 2, a metal cabinet body 30 and a sheet metal shelf 40, wherein the support 1 comprises a clamping portion 10 and a supporting base 13 mounted at the bottom of the clamping portion 10, a mounting hole 11 is provided in the middle of the clamping portion 10 of the support 1, at least one clamping device 21 is installed at one end of the mounting seat 2, a clamping slot 20 is provided in the middle of one end of the mounting seat 2, a square slot 27 is also provided at the top of the mounting seat 2, and a clamping slot 41 is provided at one end inside the sheet metal shelf 40.

[0037] Specifically, the mounting hole 11 of the bracket 1 is mounted on the metal cabinet 30 by means of screws or other connecting parts. The engaging device 21 of the mounting seat 2 is engaged with the engaging groove 41 at one end inside the sheet metal layer 40, so that the mounting seat 2 is mounted on one end surface inside the sheet metal layer 40, and the mounting seat 2 is completely hidden inside the sheet metal layer 40. When assembling the metal cabinet 30 and the sheet metal layer 40, it is only necessary to align the engaging groove 20 of the mounting seat 2 with the engaging portion 10 of the bracket 1 and directly insert and install.

[0038] In this embodiment, the number of the engaging devices 21 on the mounting seat 2 is four. In other embodiments, the number of the engaging devices 21 can be one, two or other numbers. When the number of the engaging devices 21 on the mounting seat 2 is set to four, the four engaging devices 21 are respectively arranged on the four corners of one end of the mounting seat 2. The one engaging device 21 includes an engaging opening 22 and an engaging convex ridge 23 installed inside the engaging opening 22. The engaging convex ridge 23 is a rectangular parallelepiped, and the height of the rectangular parallelepiped of the engaging convex ridge 23 is lower than the top of the engaging opening 22 where the rectangular parallelepiped is located.

[0039] A first flush frame 25 is installed on the end face of the locking slot 20 at one end of the mounting seat 2. At the same time, the sheet metal layer 40 is a sheet metal processed part. The side surface located on the side of the locking slot 41 of the sheet metal layer 40 is the mounting side surface. A reserved hole position for mounting side surface matching with the first flush frame 25 can be opened on the mounting side surface. The reserved hole position for mounting side surface is used to place the first flush frame 25. The first flush frame 25 has two functions. The first function is to limit the movement of the mounting seat 2 in the vertical direction after the mounting seat 2 and the sheet metal layer 40 are installed; the second function is to align with the mounting side surface of the sheet metal layer 40, so that the mounting side surface of the sheet metal layer 40 visually presents a flat effect, meeting the user's needs for beauty and simple design.

[0040] Please refer to Figure 4 , Figure 4This is an embodiment of the mounting base 2 being snap-fitted and connected to the sheet metal layer 40. The mounting base 2 is snap-fitted and connected to the sheet metal layer 40 and is firmly mounted on one end of the sheet metal layer 40. The specific operation principle is as follows: the mounting base 2 is first lifted toward the upper direction of the slot 41 of the sheet metal layer 40, and then, one end face of the mounting base 2 is pushed and attached to one end of the sheet metal layer 40. Then, the mounting base 2 is moved downward so that the rectangular parallelepiped on the snap-fitting ridge 23 is snap-fitted and connected to the slot 41 of the sheet metal layer 40. At this time, one side of the snap-fitting opening 22 is against one end face of the slot 41 of the sheet metal layer 40. When the rectangular parallelepiped is completely snap-fitted with the slot 41, the mounting base 2 is continued to be pushed toward the reserved hole position of the installation side surface of the sheet metal layer 40, so that the first flush frame 25 is inserted into the reserved hole position of the installation side surface of the sheet metal layer 40. At this time, the end face of the first flush frame 25 is aligned with the installation side surface of the outer side of the sheet metal layer 40. The first flush frame 25 prevents the mounting seat 2 from moving relative to the sheet metal layer 40 in the vertical direction. When the bracket 1 is engaged with the mounting seat 2, the bracket 1, the engaging ridge 23 and the engaging opening 22 jointly restrict the mounting seat 2 from moving relative to the sheet metal layer 40 in the horizontal direction. Therefore, the above-mentioned specific actions solve the problem of how to stably mount the mounting seat 2 on the sheet metal layer 40.

[0041] In this embodiment, the geometric shape of the engaging portion 10 of the bracket 1 is a wedge-shaped structure, and the geometric shape of the engaging notch 20 of the mounting seat 2 is a wedge-shaped notch structure, and the wedge-shaped structure matches the wedge-shaped notch structure. Figure 3 , in the cross section of the wedge-shaped structure, the shape of the wedge-shaped structure is a trapezoid that is narrow at the top and wide at the bottom; in the cross section of the wedge-shaped notch structure, the shape of the wedge-shaped notch structure is a trapezoid that is narrow at the top and wide at the bottom. The trapezoidal area on one side of the wedge-shaped structure is smaller than the trapezoidal area on the other side, and the trapezoidal area of ​​the notch on one side of the wedge-shaped notch structure is smaller than the trapezoidal area of ​​the notch on the other side. In other embodiments, the geometric shape of the clamping portion 10 of the bracket 1 can be a triangular wedge-shaped structure, a parallelogram wedge-shaped structure, a snap block or other special-shaped wedge-shaped structures. Similarly, the geometric shape of the clamping notch 20 of the mounting seat 2 can be a triangular wedge-shaped notch structure, a parallelogram wedge-shaped notch structure, a snap notch or other special-shaped wedge-shaped notch structure that matches the clamping portion 10 of the bracket 1.

[0042] See also Figure 1 and Figure 2The specific engagement principle of the support 1 and the mounting seat 2 is as follows: the mounting seat 2 is located vertically above the support 1, and the mounting seat 2 is pushed downward, and the engagement notch 20 is inserted into the engagement portion 10 to achieve engagement connection. After engagement connection, the engagement portion 10 and the engagement notch 20 are interference fit, so that the support 1 and the mounting seat 2 are locked after engagement, wherein the trapezoidal structure of the wedge-shaped structure of the engagement portion 10 and the trapezoidal structure of the wedge-shaped notch structure of the engagement notch 20 are matched, and the locking design of the trapezoidal inclined surface makes its engagement structure more secure, and furthermore, through the size change of the side trapezoidal shape of the wedge-shaped structure, and the size change of the side trapezoidal shape inside the wedge-shaped notch structure, the support 1 and the mounting seat 2 are completely locked in the horizontal direction after engagement, and cannot be separated in the horizontal direction.

[0043] After the bracket 1 is engaged with the mounting seat 2 , the bracket 1 and the mounting seat 2 are completely hidden between the metal cabinet 30 and the sheet metal layer 40 .

[0044] Please refer to Figure 1 and Figure 5 In this embodiment, a second flush frame 26 is installed at the bottom of the mounting seat 2, and the support base 13 of the bracket 1 is placed inside the second flush frame 26. The shape of the support base 13 is arc-shaped, and the contour shape of the support base 13 is consistent with the internal contour shape of the second flush frame 26, and the internal contour shape of the second flush frame 26 is arc-shaped. Since the sheet metal layer 40 is a sheet metal processing part, the bottom of the sheet metal layer 40 is the installation bottom surface, and a reserved installation bottom surface hole matching the second flush frame 26 can be opened on the installation bottom surface. The reserved installation bottom surface hole is used to place the second flush frame 26. The function of the second flush frame 26 is to align with the installation bottom surface of the sheet metal layer 40, so that the installation bottom surface of the sheet metal layer 40 visually presents a flat effect, meeting the user's needs for beauty and simple design.

[0045] A square notch 27 is formed on the top of the mounting seat 2. The square notch 27 is designed to reduce the weight of the mounting seat 2 and reduce the production cost.

[0046] In summary, the structural design of the clamping device 21 of the mounting seat 2 solves the problem of the mounting seat 2 being stably mounted on the sheet metal layer 40, and the structural matching design of the clamping portion 10 of the bracket 1 and the clamping notch 20 of the mounting seat 2 solves the problem of the sheet metal layer 40 being stably mounted on the metal cabinet 30. The mounting seat 2 and the bracket 1 form a hidden layer support of the present embodiment, which is easy to assemble and disassemble, has a firm structure, has sufficient supporting force to hold up the sheet metal layer 40, and makes the connection between the metal cabinet 30 and the sheet metal layer 40 aesthetically pleasing as a whole. This simple design brings a comfortable visual experience to the user.
