Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electric wire wiring, especially to a single pipe one-out multi-branch box for electric wire wiring. BACKGROUND

[0002] The main reasons for using branch boxes in electric wire layout include protecting the end of the electric wire, facilitating maintenance and beautifying the line. The branch box can protect the electric wire joint, prevent the electric wire from being damaged at the joint, and facilitate future maintenance and modification. For example, the patent authorized publication No. CN207638290U discloses a branch device convenient for wiring in load-bearing walls, which is usually used for wiring in load-bearing walls, shear walls, over-beams and suspended ceilings. The caliber of the one end of the main wire pipe is large, forming a thick thickness, while the caliber of the one end of the branch wire pipe is small, forming a thin thickness. The box body of the branch box is in isosceles trapezoidal structure, so that the depth of the slotting in the wall can be reduced to minimize the impact on the function of the wall. The branch device in the prior art is integrally injection molded. For the multiple electric wires coming in from the end of the main wire pipe, each branch wire pipe end needs to be passed through. Since the caliber of the branch wire pipe end is usually 8-8.2mm, it is not easy to align and insert, which causes trouble for operation and construction. On the other hand, for the existing branch device, the end of the main wire pipe and the end of the branch wire pipe are both hollow cylindrical connection ends connected with PVC straight pipes. However, the corrugated pipe cannot be directly connected because there are 90-degree perpendicular connecting surfaces between the wall and the wall, the ground and the ceiling during wiring. It is not so convenient and fast to select the bending degree and adjust the direction of connection through the PVC elbow pipe. Therefore, it is necessary to optimize and improve the existing branch device. SUMMARY

[0003] Therefore, the utility model provides a single pipe one-out multi-branch box, which solves the problem that the existing integrated branch box is difficult to align with the branch wire pipe end and cannot connect the corrugated pipe.

[0004] The technical scheme disclosed by the utility model relates to a single pipe one-out multi-branch box. The branch box comprises a branch box main body and a cover body. The branch box main body comprises a wire passing cavity with an open upper end. A main wire pipe connection end is arranged on the left side of the wire passing cavity and connected to the inside of the wire passing cavity. A plurality of branch wire pipe connection ends are arranged on the right side of the wire passing cavity and connected to the inside of the wire passing cavity. The branch wire pipe connection ends are arranged side by side. Hollow cylindrical connection ends are arranged on both sides of the main wire pipe connection end and both sides of the branch wire pipe connection end in the wire passing cavity. The bottom of the cover body is provided with plug-in feet which are tightly fitted and plugged into the hollow cylindrical connection ends.

[0005] Further, three branch wire pipe connection ends are arranged side by side on the right side of the wire passing cavity. The main wire pipe connection end and the branch wire pipe connection end are both hollow cylindrical connection ends, and the hollow cylindrical connection ends and the wire passing cavity are integrally injection molded by flame-retardant plastic material.

[0006] Further, the wire passing cavity is left high and right low, and the cross section of the wire passing cavity is isosceles trapezoidal.

[0007] Further, the opposite position of the side wall of the main line pipe connecting end is provided with a spring buckle part.

[0008] Further, the opposite position of the side wall of any one or any two or three of the branch line pipe connecting ends is provided with a spring buckle part.

[0009] Further, the spring buckle part comprises a notch position, a spring is arranged on the side of the notch position away from the wire passing cavity, and a hook part is arranged on the front end bottom of the spring, and the cross section of the hook part is triangular.

[0010] The beneficial effects of the utility model are that: the branch line box designed according to the technical scheme is connected with a large-diameter main line pipe at the main line pipe connecting end, and is connected with a small-diameter single line pipe at each branch line pipe connecting end; a plurality of electric wires are arranged in the main line pipe; the plurality of electric wires are manually branched in the wire passing cavity; and the electric wires are manually inserted through the through hole of the branch line pipe connecting end; after the insertion, the cover body is covered with the box body, and the operation is convenient and fast. On the other hand, the spring buckle part is arranged at the main line pipe connecting end and / or the branch line pipe connecting end; the spring buckle part can quickly connect the corrugated pipe; the pipe wall groove of the corrugated pipe is clamped with the spring buckle part, and is not easy to loosen and fall off; and the corrugated pipe can be flexibly bent in each direction, so that the branch line box provided with the spring buckle part can meet the installation requirement of the curved pipeline during line wiring, and brings convenience to engineering construction.
