[0002] Power fittings are metal accessories that connect and combine various devices in the power system and play a role in transmitting mechanical loads, electrical loads and providing some protection. According to their functions and structures, they can be divided into suspension clamps, tension clamps, UT clamps, connection fittings, splicing fittings, protection fittings, equipment clamps, T-type clamps, busbar fittings, and wire pulling fittings. According to their uses, they can be used as line fittings and transformer fittings, among which suspension clamps are important load-bearing parts for suspending tubular busbars.

[0003] The existing tubular busbar suspension clamp is an important force-bearing member used for tubular busbar suspension. The clamp is fixed on the busbar and suspended by a suspension frame on the top of the clamp. However, it has the following defects:

[0004] (1) When the existing tubular busbar suspension clamp is in use, the clamping inner diameter of the clamp is fixed, while the existing tubular busbar outer diameter specifications are diversified, which leads to the problem of relatively single use of the clamp. For this reason, we propose an adjustable tubular busbar suspension clamp. Utility Model Content

[0005] The utility model aims to provide an adjustable tubular busbar suspension clamp to solve the problem that the tubular busbar suspension clamp proposed in the above background technology is limited by its inner diameter when suspending the tubular busbar and can only be assembled with a matching busbar, resulting in a single scope of use.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable tubular busbar suspension wire clamp, comprising a wire clamp ring, the outer wall of the wire clamp ring is sleeved with a driving bevel gear disk, the side wall of the wire clamp ring is inlaid with four screw barrels in a circular array, one end of the screw barrel is connected to a stud through a thread, one end of the stud is connected to a clamping plate, the other end of the screw barrel is connected to a driven bevel gear, and the driven bevel gear and the driving bevel gear disk are connected by meshing.

[0007] Preferably, a limiting groove with a circular cross-section is provided on the outer wall of the screw barrel, and a side pin is provided on one side of the inner end of the limiting groove, and the side pin is fixed on the wire clamp ring.

[0008] Preferably, positioning plates are provided on both sides of the outer wall of the driving bevel gear disc, and the positioning plates are fixed on the outer wall of the wire clamp ring.

[0009] Preferably, guide rods are fixed on both sides of the clamping plate, and guide cylinders are sleeved on the outer walls of the guide rods, and the guide cylinders are embedded in the wire clamp rings.

[0010] Preferably, the longitudinal section of the clamping plate is an arc-shaped structure, and the longitudinal section of the wire clamp ring is a circular structure.

[0011] Preferably, a rubber pad is fixed on the surface of the clamping plate.

[0012] Preferably, a hanger assembly is fixed to the outer wall of the wire clamp ring, and the hanger assembly consists of a hanger and a locking bolt.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) Through the designed wire clamp ring, driving bevel gear, driven bevel gear, screw barrel, stud and clamping plate, the four clamping plates are distributed in a circular array in the wire clamp ring. The driving bevel gear rotates, and the driving bevel gear engages with the four driven bevel gears at the same time, driving the four screw barrels to rotate at the same time, thereby realizing the simultaneous adjustment of the positions of the four clamping plates. The inner busbar is clamped and fixed by the four clamping plates to ensure that the clamping inner diameter of the utility model is adjustable, which is compatible with busbars of different specifications and has a wider range of uses. Through the designed side pins and limit grooves, the rotation of the screw barrel is limited on the wire clamp ring to avoid separation from the wire clamp ring. Through the designed positioning plate, the driving bevel gear is limited to avoid moving on the wire clamp ring and separating from the driven bevel gear. Through the designed guide barrel and guide rod, the clamping plate is adjusted and guided to avoid displacement and affecting the clamping effect of the busbar. Through the designed rubber pad, the surface of the clamping plate is guaranteed to be soft, thereby avoiding damage to the busbar clamping. BRIEF DESCRIPTION OF THE DRAWINGS
