The terminal beam assembly includes two support frames symmetrically arranged on the bottom plate of the instrument room, and a terminal beam rotatably arranged on the two support frames. Two adjusting bolts are arranged at both ends of the terminal beam and are matched with the two support frames. Arc - shaped adjusting holes are respectively arranged on the two support frames and are matched with the two adjusting bolts. The two adjusting bolts pass through the arc - shaped holes and are connected to the threaded holes at both ends of the terminal beam.

[0005] The beneficial effects of the above - mentioned structure are as follows: The terminal beam is rotatably connected to the two support frames. When installing the terminal block, the terminal beam can be rotated arbitrarily. By tightening the adjusting bolts, the terminal beam can be fixed at the required angle, which is convenient for the assembly of the terminal block and the terminal beam and also convenient for the wiring of the terminal block, making the wiring more convenient. Moreover, the terminal beam assembly adopts a modular structure design, which is convenient for the assembly of the terminal beam and the bottom plate, and the assembly efficiency is higher. Therefore, the switch cabinet with a flip - type terminal beam has the advantages of simple structure, stable and reliable performance, convenient assembly and convenient wiring.

[0006] Specifically, the instrument support assembly includes a support member disposed on the rear sealing plate of the instrument chamber, a fixing member disposed on the rear sealing plate at one side corresponding to the support member, and an instrument mesh plate. Two hinges are respectively disposed between one side of the instrument mesh plate and the support member. A bolt connected to the fixing member is disposed on the other side of the instrument mesh plate. Fixing holes for fixing the instrument are respectively disposed on the instrument mesh plate. The instrument support assembly adopts a modular structure design, so as to facilitate the modular assembly of the instrument support assembly and the rear sealing plate, and the assembly efficiency is higher.

[0007] Specifically, a support plate abutting against the lower end of the other side of the instrument mesh plate is disposed on the fixing member. The support plate plays a supporting role for the instrument mesh plate, and can ensure that the connection between the instrument mesh plate and the fixing member is more compact.

[0008] Specifically, a positioning shaft is respectively disposed at both ends of the terminal beam. Positioning holes matching the positioning shafts are respectively disposed on the two support frames. The positioning shafts are inserted into the positioning holes, and a rotational connection and cooperation between the positioning shafts and the two support frames are formed. The terminal beam is connected to the two support frames through the positioning shafts, so as to facilitate the assembly of the terminal beam and the two support frames, and can ensure that the terminal beam can act reliably on the two support frames.

[0009] Specifically, the shape of the support frame is L-shaped. Fixing holes connected to the bottom plate are disposed on the fixing portion at one end of the support frame. The arc-shaped adjustment hole is disposed on the support portion at the other end of the support frame. The support frame adopts an L-shaped structure design, so as to facilitate the assembly of the support frame and the bottom plate, and the assembly is more convenient. Description of the Drawings
