DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] A solid insulated closed switch cabinet comprises a cabinet body 1 and a back sealed door 2. The cabinet body 1 is provided with wires 3 for connecting electrical appliances inside the cabinet body and external equipment. Guide grooves 4 are provided on both sides of the inner wall of the cabinet body 1. Guide protrusions 5 are fixedly connected to both sides of the back sealed door 2. The guide grooves 4 and the guide protrusions 5 are slidably connected.

[0028] A positioning plug-in is provided on one side of the back sealing door 2, and the positioning plug-in includes a limiting portion 601 and a plug-in portion 602. An opening for the plug-in portion 602 to pass through is provided on the back sealing door 2. A first positioning sleeve 7 is fixedly connected to the top of the cabinet 1, and a second positioning sleeve 8 is fixedly connected inside the cabinet 1. The first positioning sleeve 7 and the second positioning sleeve 8 are both adapted to the plug-in portion 602.

[0029] like Figure 1 and Figure 2The cabinet 1 is a solid insulated closed switch cabinet in the prior art. The back sealed door 2 and the wires 3 are both on the back side of the cabinet 1. A partition is provided inside the cabinet 1 to separate the space so as to facilitate wiring on the back side of the cabinet 1. The plug-in portion 602 passes through the back sealed door 2 and the first positioning socket 7. The plug-in portion 602 abuts against the top of the cabinet 1 to prevent the cabinet door 2 from falling. The cabinet door 2 can only move up and down through the sliding connection of the guide slide 4 and the guide protrusion 5.

[0030] A rubber gasket 9 is fixedly connected to the cabinet body 1 , a handle 10 is fixedly connected to the back sealing door 2 , and anti-slip grooves are provided on both sides of the limiting portion 601 .

[0031] like Figure 1 The rubber gasket 9 can reduce the impact force when the back sealing door 2 falls, and the anti-slip grooves on both sides of the limiting part 601 can facilitate manual pulling of the limiting part 601.

[0032] A top cover sleeve 11 is fixedly connected to the top of the back sealing door 2 , and a covering groove 12 for use with the first positioning sleeve 7 is provided at the bottom of the top cover sleeve 11 .

[0033] like Figure 1 , Figure 2 and Figure 3 After the back sealing door 2 falls, the top cover sleeve 11 covers the outside of the first positioning sleeve 7 through the covering groove 12, which plays an auxiliary positioning role for the back sealing door 2.

[0034] A mounting block 13 is fixedly connected to one side of the back sealing door 2, a mounting spring 14 is fixedly connected inside the mounting block 13, a mounting plug plate 15 is fixedly connected to the bottom of the mounting spring 14, and a mounting slot 16 used in conjunction with the mounting plug plate 15 is provided on the top of the limiting portion 601.

[0035] like Figure 1 , Figure 5 and Figure 7 The installation plug plate 15 passes through the installation slot 16 to position the limiting portion 601 to prevent the limiting portion 601 and the plug-in portion 602 from being separated from the back sealing door.

[0036] An adjusting notch 17 is provided on one side of the mounting sleeve 13 , and an operating link 18 is fixedly connected to one side of the mounting plug plate 15 . The operating link 18 and the adjusting notch 17 are slidably connected.

[0037] like Figure 7 By pulling the operating connecting rod 18 outside the installation sleeve 13, the installation plug plate 15 inside the installation sleeve 13 can be driven to move together.

[0038] A partition 19 is fixedly connected inside the cabinet 1, and a plurality of mounting slots 20 are provided on the partition 19. A cable arrangement board 21 for positioning cables is provided inside the cabinet 1, and a mounting protrusion 22 for use with the mounting slots 20 is fixedly connected to one side of the cable arrangement board 21, and elastic clamping members 23 are fixedly connected to both ends of the cable arrangement board 21.

[0039] like Figure 1 and Figure 6 By clamping the mounting protrusions 22 into different mounting slots 20, the cable board 21 can be clamped to different heights inside the cabinet 1. There are arc-shaped recesses on the inside of the cable board 21 for positioning the cables. The two ends of the cable board 21 can be pressed against the inside of the cabinet 1 to enhance the stability of the cable board 21.

[0040] The working principle of a solid insulation enclosed switch cabinet provided by the utility model is as follows:

[0041] When the back sealed door 2 needs to be closed, the operating link 18 is first pulled upward to drive the installation plug plate 15 to move upward, so that the installation plug plate 15 is separated from the limiting portion 601. At this time, the limiting portion 601 and the plug-in portion 602 can be pulled out from the back sealed door 2 to one side, and then the back sealed door 2 can be moved downward to close the cabinet 1. Then, the plug-in portion 602 passes through the back sealed door 2 and is plugged into the second positioning sleeve 8 to position the back sealed door 2.

[0042] Then, the operating link 18 is released, and the installation spring 14 presses down the installation plug plate 15, so that the installation plug plate 15 passes through the installation slot 16, and the limiting portion 601 and the plug-in portion 602 are fixed, so that the plug-in portion 602 will not be loosened;

[0043] Similarly, when the back sealing door 2 needs to be opened, the operating link 18 can be pulled upward, and then the limiting portion 601 and the plug-in portion 602 can be pulled out. At this time, the handle 10 can be pulled upward to drive the back sealing door 2 to slide up and down, and the back sealing door 2 can be opened. Then, the plug-in portion 602 can be passed through the back sealing door 2 and plugged into the first positioning sleeve 7 to position the back sealing door 2.

[0044] Compared with the related art, the solid insulation enclosed switch cabinet provided by the utility model has the following advantages:

[0045] Beneficial effects:

[0046] By providing a back sealing door 2 that can move up and down, the cabinet 1 can be quickly opened and closed by moving the back sealing door 2 up and down. When the back sealing door 2 is opened, it will not occupy the space outside the cabinet 1, which is convenient for wiring and maintenance of the cabinet 1 in a limited space. At the same time, by plugging the plug-in part 602 into the first positioning socket 7 or the second positioning socket 8, the back sealing door 2 can be quickly positioned after opening or closing.

[0047] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
