DETAILED DESCRIPTION

It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

An embodiment of the present invention is shown in conjunction with FIGS. 1 to 5 .

As shown in Figures 1 and 5, for the overall structure, in this embodiment, a low-voltage withdrawable switch cabinet includes: a cabinet body 1 with a hollow front, the cabinet body 1 is formed by splicing a front door panel 2, a main body mounting plate 3 and an internal connecting plate 4, the main body mounting plate 3 is a U-shaped frame structure, which corresponds to the upper and lower sides and the back of the cabinet body 1 and has corresponding positioning holes 5 on each side, the upper and lower ends of the front door panel 2 are exposed to the main body mounting plate 3, and are fixed to the main body mounting plate 3 at the corresponding intersections by a first fixing member 6 and a second fixing member 7, respectively, and the main body mounting plate 3 is equidistantly provided with a plurality of groups of vertical grooves 8 for installing electrical components on a surface corresponding to the back of the cabinet body 1, a main circuit dynamic connector 9 and a secondary dynamic connector 10 are inserted and fixed on the internal connecting plate 4, and a nut lock 11 is fixed to the part of the main body mounting plate 3 exposed at the bottom of the front door panel 2, and the nut lock 11 is used to threadably cooperate with an external screw to realize the outward displacement of the cabinet body 1 as a whole.

In this embodiment, the first fixing member 6 and the second fixing member 7 include at least two each, and are arranged symmetrically along the center of the main body mounting plate 3 .

Through the above structure, the cabinet body 1 with an opening 14 on the front can be pulled out and displaced outward through the nut lock 11 at the bottom and the transmission components such as the external screw. When the actual cabinet body 1 is installed, the switch cabinet includes not only one, but can be assembled and integrated in groups up and down or left and right, which is convenient for the installation needs of multiple devices. When maintenance or equipment adjustment is required, it is only necessary to rely on the wrench to rotate the corresponding nut lock 11. Under the action of the thread, the cabinet body 1 of each switch cabinet can be displaced axially with the external screw, so that it is easy to pull out. After pulling out, the electrical components and related connecting lines are exposed on the front, and the operation and maintenance process is more convenient.

As shown in Figure 3, the first fixing member 6 includes a right-angle L-shaped connecting block 12 and a connecting plate 13 overlapped on the top of the front door panel 2. An opening 14 is opened along the edge of the top of the front door panel 2. One end of the connecting block 12 is positioned in the opening 14 with an axial pin, and the other end is provided with a connecting hole 15 for screwing the positioning hole 5. The connecting plate 13 is also an L-shaped structure, one end of which is correspondingly buckled on both sides of the top of the opening 14, and the other end is fixed to the main mounting plate 3 with screws.

As shown in Figure 4, the second fixing member 7 includes a bottom block 16 and an inverted U-shaped insert 17. A positioning pin 18 is protruded corresponding to the bottom inner wall of the front door panel 2. One end of the second fixing member 7 is fixed by the positioning pin 18, and the other end is embedded in the insert 17. The bottoms of both ends of the insert 17 are fixed to the positioning holes 5 on the main mounting plate 3 by screws.

Through two independent fixing structures, the upper and lower ends of the front door panel 2 can be fixed respectively, so as to ensure that the front door panel 2 will not be easily deformed when pulled out by external force, and the durability is higher. The two fixing structures are also designed to be both hidden and simple, easy to install, and the overall fixing effect is better.

Further, as shown in FIG2 , the front door panel 2 is also provided with an instrument panel area 19. The front door panel 2 is also provided with a double-holding handle 20. The instrument panel area 19 is used for subsequent installation of an operating instrument screen, etc., and sufficient space is reserved. The handle 20 can assist the operator in pulling out the cabinet 1, which is more labor-saving.

The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
