[0034] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0035] like Figures 1 to 13 As shown, a low-voltage withdrawable switch cabinet in one embodiment of the utility model includes a main cabinet 1, and a plurality of cabinet slots 11 are provided on the main cabinet 1, and a sub-cabinet 2 is slidably connected in each cabinet slot 11. The sub-cabinet 2 is installed with power cords and electrical components, and the sub-cabinet 2 and the electrical components, power cords and other components therein constitute a control box that can independently control a certain electrical device, and a plurality of control boxes are installed in the main cabinet 1 for convenient centralized management.
[0036] like Figures 1 to 12As shown, two second slide grooves 13 arranged opposite to each other are provided on the inner side wall of the main cabinet 1, and a first slide bar 21 matching the second slide groove 13 is fixedly connected to the sub-cabinet 2, and the sub-cabinet 2 is slidably connected in the cabinet groove 11 through the cooperation of the first slide bar 21 and the second slide groove 13. A first locking assembly matching the sub-cabinet 2 is also provided on the side wall of the main cabinet 1, and the first locking assembly is used to lock the main cabinet 1 and the sub-cabinet 2 to ensure that the sub-cabinet 2 is not completely pulled out. A third slide groove 14 is provided on the outer side of one of the side walls provided with the second slide groove 13, and a connecting groove 15 is provided between the third slide groove 14 and the second slide groove 13, and the third slide groove 14, the connecting groove 15 and the second slide groove 13 are T-shaped. The first locking assembly includes a second slider 6, which is slidably connected in the third slide slot 14, and a second bolt 7 is threadedly connected to the second slider 6. A second threaded hole 211 matching the second bolt 7 is provided on the first slide bar 21, and the second bolt 7 passes through the second slider 6 and the connecting slot 15, and can be threadedly connected with the second threaded hole 211. Since the third slide slot 14 is opened and closed in the middle of the main cabinet 1, when the second slider 6 is fixed to the first slide bar 21 by the second bolt 7, the sub-cabinet 2 cannot be completely pulled out of the cabinet slot 11. If the sub-cabinet 2 is to be completely pulled out, the second bolt 7 needs to be loosened so that the second bolt 7 and the first slide bar 21 lose connection.
[0037] like Figures 1 to 12 As shown, a slide plate 3 is also provided between the bottom wall of the sub-cabinet 2 and the bottom wall of the cabinet slot 11, and the slide plate 3 and the bottom wall of the cabinet slot 11 are slidably connected. Specifically, the cabinet slot 11 is provided with a first slide slot 12, and a second slide bar 31 matching the first slide slot 12 is fixedly connected to the slide plate 3, and the second slide bar 31 and the first slide slot 12 are slidably connected. A second locking assembly is provided on the side wall of the slide plate 3, and the second locking assembly is used to fix the main cabinet 1 and the slide plate 3. When the second locking assembly is locked, the sub-cabinet 2 is slid in the cabinet slot 11, and the slide plate 3 will not be slid along with it.
[0038] Specifically, Figures 1 to 13 As shown, the second locking assembly includes a handle 34, and the handle 34 is fixedly connected to the second slide bar 31. A fourth slide groove 16 matching the handle 34 is provided on the main cabinet 1, and the fourth slide groove 16 is arranged along the direction in which the first slide groove 12 is opened, and the length is equal to the length of the first slide groove 12. That is, when the handle 34 slides, it can slide the slide plate 3 in the cabinet groove 11. A first threaded hole 17 is provided at one end of the fourth slide groove 16, and a third bolt 8 is threadedly connected to the fourth slide groove 16, and the third bolt 8 passes through the fourth slide groove 16 and is threadedly connected to the first threaded hole 17. When the third bolt 8 passes through the fourth slide groove 16 and is threadedly connected to the first threaded hole 17, the slide plate 3 is locked.
[0039] like Figure 5As shown, the upper end surface of the slide plate 3 is provided with a fifth slide groove 32, and the first slider 4 is slidably connected in the fifth slide groove 32. The first slider 4 is threadedly connected with a first bolt 5, and the first bolt 5 can penetrate the first slider 4 and be threadedly connected with the bottom of the sub-cabinet 2. That is, the sub-cabinet 2 can be selectively slidably connected to the slide plate 3. Specifically, the slide plate 3 is provided with a sixth slide groove 33 that matches the first bolt 5. When the first bolt 5 and the sub-cabinet 2 are threadedly connected, the first bolt 5 can be completely received in the sixth slide groove 33, and will not affect the sliding of the sub-cabinet 2 on the slide plate 3.
[0040] like Figures 9 to 12 As shown, the slide plate 3 can be slidably connected in the cabinet slot 11, and can also be slidably connected to the slide plate 3. The slide plate 3 can be pulled out separately. Therefore, when the sub-cabinet 2 is fully pulled out, it can also slide on the slide plate 3. The slide plate 3 can be used as a temporary workbench to provide convenience for the staff to maintain the electrical components in the sub-cabinet 2. When maintaining the high-rise sub-cabinet 2, there is no need to disassemble the sub-cabinet 2, and there is no need to disassemble the related power cord, etc. The slide plate 3 and the sub-cabinet 2 can be directly pulled out to perform maintenance operations.
[0041] Specifically, when it is necessary to maintain the electrical components in the sub-cabinet 2, first, the first locking assembly and the second locking assembly need to be fully opened, and then the handle 34 is pulled to allow the slide plate 3 to slide out of the cabinet slot 11. The slide plate 3 will slide out with the sub-cabinet 2 while sliding out. Since the first locking assembly has been opened, the connection between the main cabinet 1 and the sub-cabinet 2 is lost. When the slide plate 3 slides out completely, the sub-cabinet 2 can slide on the slide plate 3, so that the sub-cabinet 2 slides out completely and is supported by the slide plate 3. The slide plate 3 is used as a temporary support table, and maintenance can be carried out directly in this state. If it is not necessary, the sub-cabinet 2 does not need to be completely removed. This reduces the workload of maintenance staff and provides certain conveniences for maintenance.
[0042] When the sub-cabinet 2 needs to be disassembled, the first bolt 5 can be removed from the bottom of the skateboard 3 when the skateboard 3 and the sub-cabinet 2 are completely pulled out, so that the skateboard 3 and the sub-cabinet 2 lose connection. At this time, the sub-cabinet 2 can be lifted upward to separate the sub-cabinet 2 and the skateboard 3, and the sub-cabinet 2 can be replaced or disassembled for maintenance.
[0043] To facilitate the positioning of the first slider 4 and the sub-cabinet 2 when they are threadedly connected, a positioning block 41 is fixedly connected to the upper end of the first slider 4. The positioning block 41 is located on the upper end surface of the slide plate 3. A positioning groove 22 matching the positioning block 41 is provided on the sub-cabinet 2. After the positioning block 41 and the positioning groove 22 are matched, the first bolt 5 and the sub-cabinet 2 can be threadedly connected by tightening the first bolt 5.
[0044] Generally, the number of the first sliding blocks 4 is at least two, and the two first sliding blocks 4 are fixed to the sub-cabinet 2 , which can improve the stability of the sub-cabinet 2 on the slide plate 3 .
[0045] like Figures 1 to 13 As shown, the length of the third chute 14 does not exceed the width of the side wall, and is located in the middle of the side wall. The length of the fourth chute 16 does not exceed the width of the side wall, and is located in the middle of the side wall.
[0046] The utility model provides a slide plate 3, and the sub-cabinet 2 is slidably connected on the slide plate 3. The slide plate 3 can be used as a temporary maintenance table, and the electrical components in the high-level sub-cabinet 2 can be maintained without completely disassembling the sub-cabinet 2, which greatly reduces the workload of maintenance personnel. The slide plate 3 can also be used as a pull-out extension plate to completely pull out the sub-cabinet 2, so that the power cord at the rear end of the sub-cabinet 2 can be easily removed. When the power cord is removed, the sub-cabinet 2 loses connection with the slide plate 3, and the sub-cabinet 2 can be removed from the slide plate 3 for maintenance.
