[0037] The specific structure of the cabinet framework 100 and the cabinet 1000 provided by the utility model will be described below:

[0038] Please refer to Figures 4 to 9In one embodiment of the cabinet skeleton 100 of the present invention, the cabinet skeleton 100 includes multiple columns 10, multiple beams 20 and a first shielding bracket 30, and the two ends of each beam 20 are fixedly connected to different columns 10, and the multiple columns 10 are all open profile structures, and the columns 10 include a first bending plate 11, a second bending plate 12, a connecting plate 15, a third bending plate 13 and a fourth bending plate 14 connected in sequence, the second bending plate 12 and the third bending plate 13 are respectively bent in opposite directions relative to the connecting plate 15, the bending direction of the first bending plate 11 relative to the second bending plate 12 and the bending direction of the fourth bending plate 14 relative to the third bending plate 13 are opposite, the first shielding bracket 30 is arranged on the third bending plate 13 or the fourth bending plate 14, and the first shielding bracket 30 protrudes from the third bending plate 13.

[0039] It can be understood that in the cabinet skeleton 100 proposed in the present invention, an open profile structure is formed by bending multiple columns 10 multiple times, thereby facilitating the subsequent spraying integrity of the columns 10 and improving the corrosion resistance of the columns 10. At the same time, a first shielding bracket 30 is provided on the third bending plate 13 or the fourth bending plate 14 of the column 10, and the first shielding bracket 30 protrudes from the third bending plate 13, so that when the door panel 200 of the cabinet 1000 is covered on the third bending plate 13, the column 10 can form a conductive connection with the door panel 200 through the first shielding bracket 30 protruding from the third bending plate 13, thereby enabling the cabinet 1000 to achieve high protection electromagnetic compatibility EMC. The first shielding bracket 30 can be set on the inner wall or outer wall of the third bending plate 13, or the first shielding bracket 30 can be set on the inner wall or outer wall of the fourth bending plate 14. In this embodiment, in order to more conveniently install the first shielding bracket 30, the first shielding bracket 30 is set on the outer wall of the third bending plate 13 or the outer wall of the fourth bending plate 14.

[0040] It should be noted that the open profile structure refers to the profile structure with an opening after bending, and the bending of the second bending plate 12 and the third bending plate 13 relative to the connecting plate 15 refers to folding the second bending plate 12 in the counterclockwise direction and folding the third bending plate 13 in the clockwise direction with the connecting plate 15 as the reference, i.e. the bending direction of the second bending plate 12 relative to the connecting plate 15 is counterclockwise, and the bending direction of the third bending plate 13 relative to the connecting plate 15 is clockwise. Similarly, the bending of the first bending plate 11 relative to the second bending plate 12 refers to folding the first bending plate 11 in the counterclockwise direction with the second bending plate 12 as the reference, and the bending of the fourth bending plate 14 relative to the third bending plate 13 refers to folding the fourth bending plate 14 in the clockwise direction with the third bending plate 13 as the reference, i.e. the bending direction of the first bending plate 11 relative to the second bending plate 12 is counterclockwise, and the bending direction of the fourth bending plate 14 relative to the third bending plate 13 is clockwise. Alternatively, the bending direction of the second bending plate 12 relative to the connecting plate 15 can also be clockwise, the bending direction of the third bending plate 13 relative to the connecting plate 15 is counterclockwise, the bending direction of the first bending plate 11 relative to the second bending plate 12 is clockwise, and the bending direction of the fourth bending plate 14 relative to the third bending plate 13 is counterclockwise.

[0041] In addition, the stand 10 of the cabinet skeleton 100 and the door plate 200 of the cabinet 1000 are usually made of metal material, and the first shielding support 30 is also made of metal material, for example, the first shielding support 30 is made of stainless steel material, so that the stand 10 forms a conductive connection between the first shielding support 30 and the door plate 200, and the cabinet 1000 can realize high protection electromagnetic compatibility EMC, reducing electromagnetic interference.

[0042] Further, please refer to Figure 4 and Figure 7 In some embodiments, the first shielding support 30 extends along the length direction Y of the stand 10.

[0043] In this way, the first shielding support 30 is in a strip shape, so as to increase the conductive area between the stand 10 and the door plate 200, thereby greatly improving the electromagnetic compatibility EMC protection level of the cabinet 1000.

[0044] Further, please refer to Figure 5 In an embodiment, the width L1 of the third bending plate 13 of at least one stand 10 is greater than the width L2 of the second bending plate 12.

[0045] In the embodiment, the width L1 of the third bent plate 13 is set to be greater than the width L2 of the second bent plate 12, so that the column 10 has higher structural strength compared with the existing C-shaped column, and the cabinet skeleton 100 using the column 10 can be more stable and can withstand high-intensity impact. Meanwhile, the door plate 200 is installed on the outer side wall of the third bent plate 13, and by setting the third bent plate 13 to be wider, the dust and sewage entering the cabinet 1000 from the gap between the door plate 200 and the cabinet skeleton 100 can be blocked to some extent, so that the cabinet 1000 has a higher protection level. Moreover, by setting the third bent plate 13 to be wider, the hinge and other components for cooperating with the door plate 200 can be arranged on the third bent plate 13, so that the opening and closing of the door plate 200 is more convenient.

[0046] It should be noted that in the embodiment, the width L1 of the third bent plate 13 of one column 10 or two columns 10 connected with the door plate 200 can be set to be greater than the width L2 of the second bent plate 12, and in other embodiments, in order to make the cabinet skeleton 100 more stable, more capable of withstanding high-intensity impact, and also having a higher protection level, the width L1 of the third bent plate 13 of the four columns 10 can be set to be greater than the width L2 of the second bent plate 12.

[0047] Please refer to Figure 6 In an embodiment, the cabinet skeleton 100 further comprises a second shielding support 40, the plurality of beams 20 are open profiles, and the beam 20 comprises a first bent surface 21, a second bent surface 22, a connecting surface 25, a third bent surface 23 and a fourth bent surface 24 connected in sequence, the second bent surface 22 and the third bent surface 23 are opposite to each other with respect to the bending direction of the connecting surface 25, the first bent surface 21 is the same as the fourth bent surface 24 with respect to the bending direction of the second bent surface 22 and the third bent surface 23, the second shielding support 40 is fixedly arranged on the third bent surface 23 or the fourth bent surface 24, and the second shielding support 40 protrudes from the third bent surface 23.

[0048] In the embodiment, the cross beam 20 for connecting two uprights 10 also adopts an open profile structure formed by multiple bending, on the one hand, to facilitate subsequent spraying integrity of the cross beam 20 and improve corrosion resistance of the cross beam 20, and on the other hand, to set the second shielding bracket 40 on the outer side wall of the third bending surface 23 or the outer side wall of the fourth bending surface 24, and the second shielding bracket 40 protrudes from the third bending surface 23, so that when the door plate 200 of the cabinet 1000 is covered on the third bending surface 23, the cross beam 20 can form a conductive connection with the door plate 200 through the second shielding bracket 40 protruding from the third bending surface 23, and then through the simultaneous use of the first shielding bracket 30 and the second shielding bracket 40, the conductive area between the cabinet framework 100 and the door plate 200 is greatly increased, so that the high protection electromagnetic compatibility EMC of the cabinet 1000 is further enhanced. The second shielding bracket 40 can be arranged on the inner side wall or the outer side wall of the third bending surface 23, or the second shielding bracket 40 can be arranged on the inner side wall or the outer side wall of the fourth bending surface 24. In the embodiment, in order to facilitate the installation of the second shielding bracket 40, the second shielding bracket 40 is arranged on the outer side wall of the third bending surface 23 or the outer side wall of the fourth bending surface 24.

[0049] It should be noted that the open profile structure refers to a profile structure having an opening after bending, and the second bending surface 22 and the third bending surface 23 are bent relative to the connecting surface 25, which means that the second bending surface 22 is folded in the clockwise direction and the third bending surface 23 is folded in the counterclockwise direction with the connecting surface 25 as the reference, i.e. the bending direction of the second bending surface 22 relative to the connecting surface 25 is clockwise, and the bending direction of the third bending surface 23 relative to the connecting surface 25 is counterclockwise. Similarly, the first bending surface 21 is folded in the counterclockwise direction with the second bending surface 22 as the reference, and the fourth bending surface 24 is folded in the counterclockwise direction with the third bending surface 23 as the reference, i.e. the bending direction of the first bending surface 21 relative to the second bending surface 22 is counterclockwise, and the bending direction of the fourth bending surface 24 relative to the third bending surface 23 is also counterclockwise. Alternatively, the bending direction of the second bending surface 22 relative to the connecting surface 25 can also be counterclockwise, the bending direction of the third bending surface 23 relative to the connecting surface 25 is clockwise, the bending direction of the first bending surface 21 relative to the second bending surface 22 is clockwise, and the bending direction of the fourth bending surface 24 relative to the third bending surface 23 is also clockwise. At the same time, the bending direction of the first bending surface 21 relative to the second bending surface 22 and the bending direction of the fourth bending surface 24 relative to the third bending surface 23 are set in the same direction, so that the first bending surface 21 can support or connect the bottom cover plate or the top cover plate or the reinforcing beam of the cabinet 1000.

[0050] In addition, the cross beam 20 of the cabinet framework 100 is usually made of metal material, and the second shielding bracket 40 is also made of metal material, for example, the second shielding bracket 40 is made of stainless steel material, so that the stand column 10 and the cross beam 20 can be electrically connected with the door plate 200 through the first shielding bracket 30 and the second shielding bracket 40 respectively. Through the cooperation of the first shielding bracket 30 and the second shielding bracket 40, the electrically conductive area between the cabinet framework 100 and the door plate 200 is greatly increased, and the electromagnetic compatibility EMC protection level of the cabinet 1000 is further improved, and the electromagnetic interference is greatly reduced.

[0051] Further, please refer to Figure 4 and Figure 7 In some embodiments, the second shielding bracket 40 extends along the length direction X of the cross beam 20.

[0052] In this way, the second shielding bracket 40 is also in the form of a long strip, which can increase the electrically conductive area between the cross beam 20 and the door plate 200, thereby greatly improving the electromagnetic compatibility EMC protection level of the cabinet 1000. As shown in Figure 7 In other embodiments, the first shielding bracket 30 also extends along the length direction Y of the stand column 10, so that the first shielding bracket 30 and the second shielding bracket 40 can be connected end to end after the cabinet framework 100 is assembled, so that a continuous and closed shielding ring is formed around the cabinet framework 100, which is electrically connected with the door plate 200. Through the shielding ring, all-around electromagnetic interference protection can be formed around the cabinet framework 100, thereby greatly improving the electromagnetic compatibility EMC protection level of the cabinet 1000.

[0053] Further, please refer to Figure 6 In some embodiments, the width L3 of the third bending surface 23 of at least one cross beam 20 is greater than the width L4 of the second bending surface 22.

[0054] In this embodiment, the width L3 of the third bending surface 23 is set to be greater than the width L4 of the second bending surface 22. On the one hand, the structural strength of the cross beam 20 can be enhanced, so that the cabinet framework 100 using the cross beam 20 can be more stable and can withstand high-strength impact. On the other hand, the first bending surface 21 and the fourth bending surface 24 can be offset in the height direction, so that a certain avoiding space is formed between the first bending surface 21 and the fourth bending surface 24, and the installation of other cabinet components on the first bending surface 21 is not affected by the fourth bending surface 24.

[0055] It should be noted that in the embodiment, the width L3 of the third bending surface 23 of one of the beams 20 of the cabinet framework 100 is greater than the width L4 of the second bending surface 22, and in other embodiments, in order to make the cabinet framework 100 more stable, more capable of bearing high-intensity impact, and also have a higher protection level, the width L3 of the third bending surface 23 of the four beams 20 at the bottom of the cabinet framework 100 or all the beams 20 of the cabinet 1000 can be set to be greater than the width L4 of the second bending surface 22.

[0056] Please refer to Figures 4 to 9 In some embodiments, mounting holes are provided on the third bending plate 13 and / or the fourth bending plate 14.

[0057] In the embodiment, the mounting holes provided on the third bending plate 13 and / or the fourth bending plate 14 can be used to mount other beams 20 of the cabinet 1000, or to mount other structural components inside the cabinet 1000, or to mount other shielding supports or other mounting supports, greatly expanding the application scenarios of the cabinet 1000. For example, the mounting holes provided on the third bending plate 13 can be used to mount the door panel 200 hinge, facilitating the opening and closing of the door panel 200; or the mounting holes provided on the fourth bending plate 14 can be used to mount the fixing support of the door panel 200, which is provided with threaded holes for fixing the door panel 200, and after the fixing support is mounted on the mounting holes of the fourth bending plate 14, the door panel 200 can be threadedly connected with the threaded holes on the fixing support through screws, so that the door panel 200 can be mounted and fixed on the cabinet framework 100; or the first shielding support 30 is pre-fixed through screws and the mounting holes, facilitating subsequent rapid welding of the first shielding support 30 on the outer side wall of the third bending plate 13 or the outer side wall of the fourth bending plate 14.

[0058] Please refer to Figure 8 and Figure 9 In an embodiment, the cabinet framework 100 further includes a reinforcing plate 50, which is arranged at the connection between the two adjacent beams 20 and the same upright column 10, and the reinforcing plate 50 is fixedly connected with the two adjacent beams 20 respectively.
