[0038] Embodiment 1

[0039] This embodiment provides an equipment cabinet. As Figure 1As shown, the equipment cabinet includes a cabinet body 20, a cabinet door 30, and a support structure 10. An opening 221 is provided on the cabinet body 20. The cabinet door 30 is movably connected to the cabinet body 20 through a connecting component so as to be able to open or close the opening 221. The support structure 10 is connected between the cabinet body 20 and the cabinet door 30 and is used to support the cabinet door 30 when the cabinet door 30 is closed, thereby avoiding the problem that the cabinet door 30 sags due to its own gravity, the excessive weight of the components on it, and other factors.

[0040] In some embodiments, the connecting component can be a hinge, so that the cabinet door 30 is pivotally connected to the cabinet body 20. In some embodiments, the connecting component can be a guide rail and a slider, so that the cabinet door 30 is slidably matched with the cabinet body 20.

[0041] In some embodiments, the equipment cabinet is a switch cabinet. The switch cabinet includes a plurality of working chambers, and at least one working chamber is provided with the above-mentioned cabinet body 20, cabinet door 30, and support structure 10. Among them, the working chamber can be an instrument chamber. In some embodiments, the equipment cabinet can also be other electrical cabinets, the cabinet body 20 of automation equipment, etc., which are not specifically limited herein.

[0042] Hereinafter, taking the equipment cabinet as a switch cabinet, and the instrument chamber of the switch cabinet includes the above-mentioned cabinet body 20, cabinet door 30, and support structure 10 as an example for detailed description.

[0043] As Figure 1 shown, the cabinet body 20 is a box structure, and an opening 221 is provided on its front side wall 22. The cabinet door 30 is pivotally connected to the cabinet body 20 through a hinge. A first flanging 23 extends forward from the edge of the opening 221. The cabinet door 30 includes a door body 31 and a second flanging 32. The second flanging 32 extends backward from the door body 31 (i.e., toward the side of the cabinet body 20). When the cabinet door 30 is in the closed state, the second flanging 32 is disposed around the outer periphery of the first flanging 23. Through the cooperation of the first flanging 23 and the second flanging 32, the sealing effect of the cabinet door 30 on the opening 221 can be improved, and thus the protection level of the equipment cabinet can be improved.

[0044] As Figures 1-3 shown, the support structure 10 includes a first support frame 11, a supporting component 120, and a second support frame 14. The first end of the first support frame 11 is installed inside the cabinet body 20. An installation hole 1121 is provided at the second end of the first support frame 11. The supporting component 120 passes through the installation hole 1121 and is connected to the first support frame 11. The second support frame 14 is connected to the cabinet door 30. The second support frame 14 is in rolling cooperation with the supporting component 120 under the drive of the cabinet door 30. When the cabinet door 30 is in the closed state, the supporting component 120 supports the second support frame 14.

[0045] For the support structure 10 of this embodiment, during the opening or closing process of the cabinet door 30, the second support frame 14 is in rolling cooperation with the supporting component 120 driven by the cabinet door 30. The rolling cooperation setting can not only reduce the wear of the second support frame 14 and improve the service life of the support structure 10, but also ensure that the opening and closing of the cabinet door 30 have relatively small resistance, ensuring smooth opening and closing of the cabinet door 30. When the cabinet door 30 is in the closed state, the supporting component 120 supports the second support frame 14, thereby playing a supporting role for the entire cabinet door 30, and further being able to avoid the problem of the cabinet door 30 sagging. In addition, compared with the solution of setting the support structure 10 on the cabinet door 30, most components of the support structure 10 of this embodiment are set on the cabinet body 20. Therefore, it will not cause a significant increase in the total weight at the cabinet door 30, and further be able to avoid the problem that the sagging tendency of the cabinet door 30 is significantly increased when it is in the open state. By adopting the above support structure 10 for the equipment cabinet, the cabinet door 30 has smooth opening and closing and a long service life.

[0046] As Figure 1 shown, in this embodiment, the first end of the first support frame 11 is installed on the bottom plate 21 of the cabinet body 20, and the supporting component 120 is located above the first end. Compared with installing the first support frame 11 on the first flanging 23, on the one hand, the structural strength of the bottom plate 21 is higher, so it can support the cabinet door 30 more reliably; on the other hand, it can avoid the width of the first flanging 23 increasing due to the installation of the support structure 10, and further avoid affecting the structural compactness of the equipment cabinet.

[0047] In some embodiments, the equipment cabinet includes a support structure 10, and this support structure 10 is installed at one end of the cabinet door 30 away from the hinge. Such a setting enables the two ends of the cabinet door 30 in the closed state to be supported by the hinge and the support structure 10 respectively, so as to better prevent the cabinet door 30 from sagging. In some embodiments, the equipment cabinet includes two or more support structures 10, and the second support frames 14 of the two or more support structures 10 can be arranged at intervals in the lower end area of the cabinet door 30.

[0048] As Figure 1 and Figure 2As shown, the first end of the first support frame 11 includes a first plate member 111, and the second end of the first support frame 11 includes a second plate member 112. The first plate member 111 and the second plate member 112 are arranged at an angle. The first plate member 111 is connected to the bottom plate 21 of the cabinet body 20, and a mounting hole 1121 is provided on the second plate member 112. By providing the first plate member 111, the contact area between the first support frame 11 and the bottom plate 21 can be increased, thereby ensuring the reliability of the connection between the first support frame 11 and the bottom plate 21, and further improving the reliability of supporting the cabinet door 30. In this embodiment, the first plate member 111 and the second plate member 112 are perpendicularly arranged. In some embodiments, through holes 1111 are provided on the first plate member 111, and the first plate member 111 is fixed to the bottom plate 21 after passing through the through holes 1111 by structures such as bolts and rivets. In some embodiments, the first plate member 111 can also be connected to the bottom plate 21 by welding. Optionally, the first plate member 111 and the second plate member 112 can be formed by bending a piece of sheet metal. In other embodiments, the first plate member 111 and the second plate member 112 can be connected by two independent plate members.

[0049] As Figure 1 and Figure 2 shown, the second support frame 14 includes a connecting plate 141 and a lapping plate 142. The connecting plate 141 and the lapping plate 142 are arranged at an angle. The connecting plate 141 is welded to the cabinet door 30. Driven by the cabinet door 30, the lapping plate 142 moves under the support of the supporting component 120. When the cabinet door 30 is in the closed state, the supporting component 120 supports under the lapping plate 142. By providing the connecting plate 141, the matching area between the second support frame 14 and the cabinet door 30 is increased; by welding the connecting plate 141 to the cabinet door 30, not only can the reliability of the connection between the second support frame 14 and the cabinet door 30 be ensured to ensure the reliability of supporting the cabinet door 30, but also the processing of holes on the cabinet door 30 can be avoided, ensuring the structural strength and protection level of the cabinet door 30.

[0050] As Figure 1 shown, a guiding arc surface 144 is provided at one end of the lapping plate 142 away from the connecting plate 141. The guiding arc surface 144 is used to guide the lapping plate 142 to lap on the supporting component 120, so as to ensure a smoother cooperation between the lapping plate 142 and the supporting component 120 and avoid wear at the end of the lapping plate 142. Specifically, the guiding arc surface 144 is provided at the lower surface of one end of the lapping plate 142 away from the connecting plate 141.

[0051] As Figure 1As shown, at one end of the guiding arc surface 144 extending away from the connecting plate 141, a reinforcing plate 143 is provided, and the reinforcing plate 143 is arranged at an angle with the overlapping plate 142. By providing the reinforcing plate 143, the structural strength of the entire second support frame 14 can be improved, ensuring the reliability of the support structure 10 for supporting the cabinet door 30. In this embodiment, the entire second support frame 14 is formed by bending a piece of sheet metal. After the reinforcing plate 143 is bent and formed, the guiding arc surface 144 is naturally formed between the reinforcing plate 143 and the overlapping plate 142, thereby reducing the processing difficulty and manufacturing cost of the support structure 10. Of course, in some embodiments, the second support frame 14 may not be provided with the reinforcing plate 143, or the reinforcing plate 143 may be provided at other positions of the overlapping plate 142. In this embodiment, the guiding arc surface 144 can be directly machined at the end of the overlapping plate 142.

[0052] As Figure 2 and Figure 3 shown, the supporting assembly 120 includes a fastener 12 and a roller 13. The fastener 12 passes through the roller 13 and the mounting hole 1121 and is connected to the first support frame 11. The roller 13 is used for rolling cooperation with the second support frame 14 and supporting the second support frame 14. By providing the fastener 12 and the roller 13, it is ensured that the second support frame 14 can be in rolling cooperation with the supporting assembly 120, and it is convenient to install the supporting assembly 120 on the first support frame 11.

[0053] As Figure 2 and Figure 3 shown, the support structure 10 further includes a nut 15. The fastener 12 includes an abutting portion 121, a penetrating portion 122, and a threaded portion 123 that are connected in sequence. The abutting portion 121 is disposed opposite to the end face of the roller 13. The penetrating portion 122 passes through the roller 13, and the threaded portion 123 passes through the mounting hole 1121 and is threadedly connected to the nut 15. Through the cooperation of the threaded portion 123, the abutting portion 121, and the nut 15, the roller 13 is reliably installed on the first support frame 11. In this embodiment, the penetrating portion 122 is a smooth shaft, so as to ensure that the roller 13 can rotate smoothly around the penetrating portion 122.

[0054] As Figure 3As shown, the cross-sectional area of the penetrating portion 122 is larger than that of the threaded portion 123. The end of the penetrating portion 122 close to the threaded portion 123 abuts against the first support frame 11, so that the installation position of the entire fastener 12 relative to the first support frame 11 can be positioned, ensuring an appropriate spacing between the second plate member 112 and the abutting portion 121. This spacing can be slightly larger than the axial dimension of the roller 13, which can not only ensure the smooth rotation of the roller 13, but also prevent excessive wear of the roller 13 and the first support frame 11 and the abutting portion 121 during rotation, thereby improving the service life of the support structure 10. Optionally, the roller 13 can be made of nylon material, which not only has high strength but also good wear resistance, and can reliably support the cabinet door 30 after long-term use.

[0055] As Figure 3 shown, the support structure 10 further includes a flat gasket 16 and an elastic gasket 17. Among them, the flat gasket 16 is sleeved on the threaded portion 123 and is disposed between the nut 15 and the first support frame 11. The elastic gasket 17 is sleeved on the threaded portion 123 and is disposed between the nut 15 and the flat gasket 16. The flat gasket 16 can increase the contact area between the nut 15 and the first support frame 11, avoid damaging the first support frame 11, and ensure the stability and reliability of the connection. The elastic gasket 17 can prevent the connection between the nut 15 and the threaded portion 123 from loosening, further ensuring the reliability of the connection. It can be understood that in some embodiments, only the elastic gasket 17 or the flat gasket 16 can be provided between the nut 15 and the first support frame 11.

[0056] Embodiment 2

[0057] This embodiment provides an equipment cabinet, whose general structure is the same as that of the equipment cabinet in Embodiment 1, except for the installation position of the support structure 10 on the equipment cabinet, which is roughly as follows:

[0058] As Figure 4 shown, in the support structure 10 of this embodiment: The first end of the first support frame 11 (i.e., the first plate member 111) is installed on the top plate 24 of the cabinet body 20. At this time, the supporting component 120 is located below the first end of the first plate member 111, and there is a spaced arrangement between the supporting component 120 and the first end of the first support frame 11. The second support frame 14 is inserted into the space between the first end of the first support frame 11 and the supporting component 120 under the drive of the cabinet door 30. At this time, the cabinet door 30 is supported on the supporting component 120 through the second support frame 14, so that the anti-drooping effect can be achieved. It should be noted that in this embodiment, in order to reduce the spacing distance between the first plate member 111 and the supporting component 120, the reinforcing plate 143 can not be provided on the second support frame 14.

[0059] In some embodiments, the equipment cabinet includes a support structure 10, which is installed at one end of the cabinet door 30 away from the hinge. Such an arrangement enables the two ends of the cabinet door 30 in the closed state to be supported by the hinge and the support structure 10 respectively, thereby better preventing the cabinet door 30 from sagging. In some embodiments, the equipment cabinet includes two or more support structures 10, and the second support frames 14 of the two or more support structures 10 can be spaced apart and arranged in the upper end area of the cabinet door 30.

[0060] Embodiment 3

[0061] This embodiment provides an equipment cabinet, whose general structure is the same as that of the equipment cabinet in Embodiment 1. The difference lies in the installation position of the support structure 10 on the equipment cabinet, which is roughly as follows:

[0062] In this embodiment, as Figure 5 shown, the equipment cabinet includes at least two support structures 10. Among them: in at least one support structure 10, the first end (i.e., the first plate member 111) of the first support frame 11 is installed on the bottom plate 21 of the cabinet body 20, and the supporting component 120 is located on the upper side of the first end of the first support frame 11. In at least one support structure 10, the first end (i.e., the first plate member 111) of the first support frame 11 is installed on the top plate 24 of the cabinet body 20, the supporting component 120 is located on the lower side of the first end of the first support frame 11 and is spaced apart from the first plate member 111, and the second support frame 14 is inserted into the space between the first plate member 111 and the supporting component 120 under the drive of the cabinet door 30. In this embodiment, both the upper and lower ends of the cabinet door 30 are supported by the support structure 10, so the effect of preventing sagging can be more significant.

[0063] In some embodiments, the equipment cabinet includes two support structures 10, one of which supports the upper end of the cabinet door 30 and the other supports the lower end of the cabinet door 30. Optionally, both of the two support structures 10 are installed at one end of the cabinet door 30 away from the hinge. Such an arrangement enables the two ends of the cabinet door 30 in the closed state to be supported by the hinge and the support structure 10 respectively, thereby better preventing the cabinet door 30 from sagging. In some embodiments, the equipment cabinet includes a plurality of support structures 10, and the plurality of support structures 10 can be flexibly distributed in the upper end area or the lower end area of the cabinet door 30.
