Description

Technical Field

[0001] This utility model belongs to the field of suspension rod installation technology, specifically relating to a suspension rod assembly and positioning structure. Background Technology

[0002] In structures such as chandeliers or chandelier fans, there are usually hanging rods and mounting brackets. In conventional structures, the mounting brackets are provided with vertical mounting channels, through which the hanging rod passes and is fixed by screws, as shown in CN202322200978.X, a lighting fixture hoisting structure and chandelier. Although this can meet the general usage needs, its stability is limited. During long-term use, the hanging rod will vibrate, which can easily cause the screws to loosen or fall off. It also fails to install safety structures such as installation ropes, thus affecting the safety of the overall structure. Utility Model Content

[0003] The purpose of this utility model is to provide a rod assembly and positioning structure that has a reasonable structural design and stable operation.

[0004] The technical solution to achieve the purpose of this utility model is a boom assembly and positioning structure, which is connected to the top of the boom and includes an assembly support. The upper part of the assembly support is provided with a circular cavity, and the lower part of the assembly support is provided with an internal threaded installation channel that is connected to and concentric with the circular cavity.

[0005] The side wall of the assembly support is provided with several positioning screw holes that communicate with the internal thread installation channel.

[0006] The side wall of the assembly support is provided with several connecting screw holes that communicate with the circular cavity.

[0007] The bottom surface of the assembly support is integrally formed with a protruding cylinder, and at least three n-shaped clearance grooves are evenly arranged on the bottom surface of the protruding cylinder.

[0008] The top of the boom is provided with an external thread, and the side wall of the boom has a locking screw hole and a safety rope through hole;

[0009] The top end of the boom is threaded into the internal thread mounting channel and positioned by the positioning screw in the positioning screw hole;

[0010] The locking screw in the locking screw hole is located in one of the n-shaped clearance grooves;

[0011] The bottom end of the safety rope passes through the safety rope hole from the top of the boom and is fitted onto the locking screw and locked by the locking screw.

[0012] A further preferred embodiment is that the inner diameter of the convex cylinder matches the inner diameter of the internal thread mounting channel.

[0013] A further preferred embodiment is that the number of positioning screw holes and connecting screw holes are the same, and the connecting screw holes are located directly above the positioning screw holes.

[0014] A further preferred embodiment is that the number of positioning screw holes is two.

[0015] A further preferred embodiment is that the bottom edge of the outer wall of the assembly support is integrally formed with a raised ring, and the raised ring is provided with a plurality of vertical holes.

[0016] A further preferred embodiment is that the assembly support and the convex ring are metal structural components.

[0017] This utility model has positive effects: Its structure is rationally designed, featuring a circular cavity on the mounting support that engages with an internal threaded installation channel. Simultaneously, the bottom surface of the mounting support has a convex cylinder that engages with an n-shaped relief groove. During assembly, the lifting rod is threaded into the internal threaded installation channel and positioned by a positioning screw in the positioning screw hole. Since the positioning screw abuts against the external thread of the lifting rod, it prevents the lifting rod from loosening or falling off due to vibration. Furthermore, the locking screw on the lifting rod, positioned within the n-shaped relief groove, limits the mounting support, preventing it from rotating in the opposite direction and causing loosening or falling off. The safety rope can pass through the lifting rod and connect to the locking screw for positioning, improving the safety and stability of the assembly. Attached Figure Description
