Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

As shown in Figures 1 to 4, a distribution frame in this embodiment includes a wiring cabinet 1 and a trunking box 2. A vertical support plate 3, a twisting coil 4 is arranged between adjacent two supporting plates 3, and the two ends of the twisting coil 4 are provided with a rotating shaft 5, and the supporting plate 3 is installed with a connecting shaft 6 through the first bearing, and the connecting shaft 6. It is detachably connected with the rotating shaft 5 through the snap-in pin. A rocker 7 is arranged outside the trunking box 2. The cross bar of the cranking handle 7 extends into the trunking box 2 through the second bearing and is connected to the outermost support plate 3. The shaft 6 is fixed, and the feature is that the top of the trunking box 2 is provided with multiple threading openings 8, and the wiring cabinet 1 is provided with a plurality of partitions 9 and vertical wiring troughs 10, and the wiring troughs 10 are provided for connecting cables. The fixing mechanism 11 is provided. The fixing mechanism 11 includes a first orifice plate 111 and a second orifice plate 112. The first orifice plate 111 and the second orifice plate 112 are respectively provided with a plurality of upper and lower corresponding first threading holes and second orifice holes. Threading hole, outside the second threading hole, a compression tube 113 stretching out from the first threading hole is set, and one end of the compression tube 113 is fixed with the second orifice 112, and the other end passes through the first threading hole and then a bowl-shaped closing tube is set. Tight head 114.

Specifically, in the distribution frame provided by this embodiment, a wiring trough 10 for easy threading is provided in the wiring cabinet 1. A fixing mechanism 11 is provided in the wiring trough 10, and the fixing mechanism 11 can be used to facilitate threading. The provided electric wires are fixed, that is, when the second orifice plate 112 leans against the first orifice plate 111 side, the electric wires can pass through the first threading hole and the second threading hole conveniently; The plate 112 moves downward, and the second orifice plate 112 drives the compression tube 113 to move, thereby contacting the bowl-shaped tightening head 114 at the end of the compression tube 113 with the outer periphery of the wire, and using the first threading hole to tighten the bowl-shaped tightening head. The extrusion of 114 completes the fixing of the corresponding electric wires. Wherein the bowl-shaped tightening head is made of shrinkable and deformable material, such as rubber or plastic, as shown in Figures 5 and 6, the bowl-shaped tightening head has an outward protrusion, which can be used in the first When the orifice plate squeezes it, use the raised part to pack inwards and stick to the outer periphery of the wire. In Figure 6, the second type of tightening head is also provided with a raised part facing the inside. Therefore, it is different from the first orifice plate. When the first threading hole on the top is matched, it has better clamping force on the wire.

In addition, since the electric wires can be laid according to the position and order of the first orifice plate 111, it will be very intuitive and convenient to determine the line to be inspected during use and maintenance; at the same time, different lines are set apart, so there is no need to replace the electric wires. It affects other wires, so it is very convenient to manage and adjust the lines.
