Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of feeder clamp, especially to a clamping structure of hoop type feeder clamp. BACKGROUND

[0002] As a fixing device, the feeder clamp is suitable for communication base station, direct broadcast station, indoor coverage system, wireless paging and microwave communication system, and plays a fixing role in the laying of transmission cable in iron tower, wiring rack, indoor and outdoor, subway and tunnel, and can be used in different high and low temperature ranges. The feeder clamp has the characteristics of economy, practicality, firmness, durability, reliable positioning and the like, and is widely used in many communication engineering.

[0003] In the existing feeder clamp, such as the hoop type feeder clamp disclosed in the authorized announcement CN 219697161 U, the upper hoop and the lower hoop are fixed together through the fixing bolts on the side edges, but under the condition of severe working environment and frequent vibration, the connection point of the traditional bolt fixing is easy to loosen, which in turn easily leads to unstable position of the feeder clamp and affects the transmission quality of communication signals. As a metal component, the bolt is easy to rust when subjected to natural environment erosion, thereby reducing the mechanical strength and connection stability of the fixing point and further affecting the long-term operation reliability of the equipment. SUMMARY

[0004] The utility model aims at solving the shortcomings in the prior art and provides a clamping structure of hoop type feeder clamp.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A clamping structure of hoop type feeder clamp, comprising an upper hoop and a lower hoop, the upper hoop and the lower hoop are connected through a connecting shaft, the outer walls of the upper hoop and the lower hoop are respectively fixedly connected with a first fixed plate and a second fixed plate;

[0007] A U-shaped hook is fixedly connected on the first fixed plate, a connecting seat is fixedly connected on the second fixed plate, a clamping piece is connected with the end of the connecting seat through a center rod, a center hole is formed in the bottom of the clamping piece, a connecting column is arranged in the center hole, installation holes are symmetrically formed on both sides of the connecting column, and a U-shaped bolt is arranged in the installation hole.

[0008] Preferably, a threaded groove is formed in the outer wall of the bottom of the U-shaped bolt, and a nut piece is sleeved on the outer surface of the threaded groove.

[0009] Preferably, a U-shaped groove is formed in one side of the inner wall of the lower hoop, and an elastic connecting ring is arranged in the U-shaped groove.

[0010] Preferably, a C-shaped clip is provided above the upper clamp, a nozzle bolt is provided in the middle of the C-shaped clip, a plastic card pressing piece is fixedly connected to the top outer wall of the upper clamp, and the nozzle bolt passes through the C-shaped clip and is connected to the plastic card pressing piece.

[0011] Preferably, the inner walls of the upper clamp and the lower clamp are provided with rubber rings, and the end of the clamping piece away from the center rod is provided with an anti-slip protective sleeve.

[0012] The beneficial effects of the utility model are:

[0013] The U-shaped hook is then tightened to lock the cable, and the nut is tightened to press the nut against the outer wall of the connecting column. At the same time, the elastic connecting ring is passed through the clamping member and tightened to the outside of the clamping member, which can effectively prevent the clamping member from loosening, thereby achieving the effect of clamping and fixing the upper clamp and the lower clamp, and ensuring the stability and reliability of the feeder clamp device.

[0014] The nozzle bolt is used to squeeze the plastic card pressing piece downward. The plastic card pressing piece is squeezed by the extrusion force and at the same time squeezes the upper clamp and the rubber ring inward, which is beneficial to fit the transmission cable tightly into the rubber ring. Then, the tightening effect of the nozzle bolt can ensure the stability of the position of the transmission cable, prevent it from falling off or loosening, and enhance the impact resistance of the feeder fixture.
