Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a rotary bracket for a distribution box. Background Technique

[0002] Distribution boxes are mainly used for the distribution and transmission of lighting power and power power, protecting the safety of electrical equipment, electrical circuits and operators. Small terminal distribution boxes can be divided into three parts: an internal box core, a box body and an external mask. The internal box core is fixed on the box body, and the external mask is fixed on the box core. The box core is the key to power distribution of the distribution box electrically. At the same time, the box core is connected to the box body and the mask structurally, combining them together.

[0003] There are various fixing methods for the box core and the box body in the market: The first fixing method is that the box core is fixed by welding screws at the bottom of the distribution box, and the mask is fixed on the mask fixing support provided on the bracket. When the installation is not standardized or the box body is buried deep in the wall, it is very difficult to adjust the height of the box core, and often the heights of the switches are inconsistent left and right and up and down. Moreover, the depth of the box with the box core fixed at the bottom can only be about 90 - 100 mm. If it is deepened to 120 mm, the stability of the screw fixing bracket is relatively poor. Another fixing method is side fixing of the bracket. This has no requirement for the depth of the distribution box and can deepen the depth of the distribution box according to user needs to meet the required requirements. Such brackets are all single-row fixed types. Each row of switches and brackets are independently fixed. The side support and the grooved plate form a single bracket. Its disadvantage is that for a distribution box with two rows of switches, its brackets are all independent and need to be installed or disassembled individually. After wiring, the installation is difficult. The distance between the two rows needs to be adjusted before the face frame can be installed. The box core is not a whole and needs to be disassembled individually. When the wiring space is small, it needs to be individually removed, the feeder is connected well and then installed on the box body. During the installation process, the connecting wires are easily damaged, resulting in an unattractive appearance. In some cases, the wire connections are also prone to looseness or breakage, affecting the power distribution reliability of the distribution box. For this reason, the utility model proposes a rotary bracket for a distribution box to solve the above problems. Content of the Utility Model
