Description

Technical Field

[0001] The utility model relates to the technical field of wire troughs, in particular to a metal wire trough connection mechanism. Background Art

[0002] Metal cable trunking is a pipe system used for laying and protecting wires and cables, and its manufacturing materials are usually metals such as steel or aluminum. They play an important role in electrical engineering, protecting wires and cables from mechanical damage, environmental corrosion, and providing physical support to ensure the safe and reliable operation of electrical systems.

[0003] At present, the metal wire trough elbows on the market are generally welded by 4 or more metal sheets due to the convenience of metal processing. Since the metal sheets used to make the wire trough are relatively thin, a square connecting block needs to be added to the welding point for welding to enhance the connection strength. However, the connecting block after welding is raised inside the elbow. During use, when the wires and cables pass through the elbow, the raised connecting block will scratch the insulation sheath, resulting in short circuit leakage, which is easy to cause fire and other safety accidents. To this end, the utility model provides a metal wire trough connection mechanism with high connection strength and safety. Summary of the invention

[0004] The purpose of the utility model is to provide a metal wire trough connection mechanism to solve the problems raised in the above background technology. To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A metal wire trough connection mechanism comprises a bottom plate, a side plate and a top plate; the upper end of the side plate is bent inwardly to form a first corner, and the lower end of the side plate is bent inwardly to form a second corner; the top plate is bent downwardly to form a third corner, and the first corner and the third corner are fixed by welding; the bottom plate is arranged on the inner side of the side plate, and the two sides of the bottom plate are fixed to the second corner by welding.

[0006] Furthermore, the first corner, the second corner and the third corner are all right angles.

[0007] Furthermore, the bottom plate is provided with a recessed portion, and the bottom side of the recessed portion is flush with the bottom side of the side plate.

[0008] Furthermore, the bottom plate, side plates and top plate are formed by laser cutting.

[0009] Furthermore, the side plate is also provided with a first connection hole, and the metal wire trough connected to the metal wire trough connection mechanism is provided with a second connection hole, and the first connection hole and the second connection hole are connected and fixed by screws.

[0010] Furthermore, the metal wire trough connection mechanism also includes a connection piece, and the connection piece is provided with a third connection hole corresponding to the position of the first connection hole, and a fourth connection hole corresponding to the position of the second connection hole.

[0011] The beneficial effect of the utility model is that the utility model can cleverly increase the thickness of the welding point by bending the side edges of the side panels and the top panel to form a corner, thereby improving the connection strength after welding without using additional connecting blocks at the welding point, avoiding the formation of bulges inside the metal wire trough connection mechanism, thereby preventing damage to the insulation skin of the wires and causing leakage accidents, and ensuring line safety.
