Description

Technical Field

[0001] The present invention relates to the technical field of cable brackets, and in particular to a cable fixing bracket and a method thereof which are easy to install. Background Art

[0002] Cable fixing racks are an indispensable part of the power system. Cable lines are supported by cable fixing racks to prevent cables from sagging and keep them stable. Cable lines are protected from damage by external factors such as impact, friction and corrosion, thus improving safety.

[0003] For example, Chinese patent CN112217161B discloses a fixing device for cable installation, which includes a U-shaped frame, a first spring, an insertion rod and a threaded rod for fastening. The distance between the U-shaped frames is changed by the threaded rod, so that cables of different types can be fixed.

[0004] However, when tightening the cable, sufficient contact area needs to be left between the tightening frame and the cable to avoid damage caused by local pressure on the cable; the cable is usually composed of multiple strands of wire covered with an insulating layer, and its cross-section is not a very regular and uniform arc; when the cable is supported by a U-shaped frame, it is difficult to make the inner side of the U-shaped frame contact with the cable completely and evenly, so it is difficult to make the cable evenly stressed.

Two mounting slots are symmetrically provided on the mounting plate, and the two mounting slots are respectively plugged into the two side plates of the fastening frame. The locking assembly is arranged on the rotating plate and the mounting frame.

[0010] Furthermore, the locking assembly includes an arc groove, a sliding rod, a locking screw and a locking nut. The sliding rod is fixedly installed on the bottom edge of the rotating plate, and an arc groove is opened on the upper side of the mounting frame; the arc groove is limitedly slidably connected to the sliding rod, and the arc center of the arc groove coincides with the rotation center of the rotating plate; a locking screw is fixedly installed on the bottom of the sliding rod, and a locking nut is threadedly connected to the locking screw.

[0016] In order to better achieve the purpose of the present invention, the present invention also provides a method for using a cable fixing bracket that is easy to install, comprising the following steps: Step 1: Install the fixing plate on the fixing frame. In the initial state, the slide bar can slide freely in the arc groove, so that the rotating plate and the mounting plate can rotate in the horizontal direction. Place the cable on the upper side of the support plate. The force on the middle part of the upper side of the support plate drives the rotating arms on both sides to rotate. The support plate holds the bottom of the cable tightly through the cooperation of the rotating arms. Step 2: After aligning the bottom plate and the limit block with the lower side of the mounting plate, align the lower sides of the two side plates of the fastening frame with the mounting grooves and insert the fastening frame into the mounting grooves until the limit block is aligned with the limit grooves, lift the fastening frame upwards to insert the limit block into the limit grooves, thereby increasing the stability of the fastening frame; rotate the rotary block, and the rotary block drives the screw to rotate; the screw rotates, and the length of the screw located at the lower side of the top horizontal plate of the fastening frame increases through the threaded sleeve between the screw and the fastening frame; the screw moves downward relative to the fastening frame, and at the same time, under the limiting action of the guide rod, drives the pressure plate to move vertically downward until the arc surface contacts the cable; the cable is pressed against the support plate through the pressure plate and the arc surface; Step 3: The bending stress in the cable drives the mounting plate and the rotating plate to rotate through the support plate and the arc surface, thereby releasing the bending stress in the cable; then tighten the locking nut on the locking screw so that the locking nut fits with the bottom of the mounting frame, thereby fixing the sliding rod through the locking screw and the locking nut, and then fixing the rotating plate and the mounting plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The lower side of the cable is supported by the support assembly, and during this process the support assembly can be adjusted according to the specific diameter and profile of the cable, thereby increasing the scope of application; the two side panels on the lower side of the fastening frame are plugged into the adjustable mounting table, the lower side of the fastening frame is limited by the adjustable mounting table and the mounting assembly, and the cable is pressed against the support assembly by the fastening assembly; thereby, the fastening frame is easy to install and the cable is easy to fix; and the support surface of the support assembly is in full contact with the cable, and the actual support area of ​​the cable can be increased by the setting of the support assembly compared to placing the cable directly on the adjustable mounting table or in the circular groove; thereby, when the cable is pressed against the support assembly by the fastening assembly, on the premise of ensuring the stability of the support, the actual support surface is avoided to be small, so that the pressure is concentrated on the cable, thereby causing damage to the cable; 2. After the cable is fastened between the fastening assembly and the supporting assembly, the cable and the fastening assembly and the supporting assembly on the adjustable mounting platform can be rotated slightly in the horizontal direction. At this time, the stress on the cable drives the adjustable mounting platform to rotate, thereby releasing the bending stress on the cable, and then the adjustable mounting platform is fixed; thereby releasing the bending stress inside the cable, avoiding the stress between the cable and the supporting assembly and the fastening assembly, which increases the pressure on the cable in the horizontal direction.
