Detailed Description
Referring to fig. 1, a power distribution cabinet with a cable locking and adjusting function is provided, and an extension fixing device is respectively installed at each threading hole A of the power distribution cabinet. The extension fixture includes: an expanding part 1, a fixing part 2 and an opening and closing part.
The fixing part 2 is a straight tube body structure and is fixedly arranged in the threading hole A. The opening and closing part consists of a first swinging plate 3 and a second swinging plate 4, and the first swinging plate 3 and the second swinging plate 4 are arc-shaped plates. The first swinging plate 3 and the second swinging plate 4 are both rotatably installed on the fixed part 2, and the concave surfaces of the first swinging plate and the second swinging plate are opposite to each other so as to clamp the cable. The first swing plate 3 and the second swing plate 4 each extend from the fixed portion 2 in a direction away from the fixed portion 2, and the distance between the first swing plate 3 and the second swing plate 4 relative to each other gradually decreases in a direction away from the fixed portion 2.
The expansion part 1 is a straight tube structure and is slidably mounted on the inner periphery of the fixing part 2. One end of the expansion part 1 is inserted between the first swinging plate 3 and the second swinging plate 4, and the other end extends out of the cabinet body B from the threading hole A. The distance between the opposing first swing plate 3 and the second swing plate 4 is proportional to the depth of insertion of the expansion portion 1 between the first swing plate 3 and the second swing plate 4.
In this way, in this embodiment, the cable passes between the first swinging plate 3 and the second swinging plate 4 after being introduced through the expansion part 1 and then enters the switch cabinet again, and the cable is clamped and fixed by the first swinging plate 3 and the second swinging plate 4, so that the cable is prevented from twisting in the threading hole, and the controllable and orderly wiring of the cable in the switch cabinet is ensured.
In the present embodiment, the opening degree between the first swing plate 3 and the second swing plate 4 can be adjusted by the feeding depth of the expansion portion, and the opening degree between the first swing plate 3 and the second swing plate 4 determines the thickness of the cable to which the extension fixture can be mated. In this way, in this embodiment, to the cable of this extension fixing device insertion cubical switchboard's different thickness, the feed degree of depth that all accessible adjusts expansion portion 1 makes extension fixing device can match with the cable, has improved the flexibility ratio of cubical switchboard fixed cable.
In this embodiment, the outer diameter of the expansion part 1 is equal to the inner diameter of the fixing part 2, so as to ensure the tightness of the threading hole after the expansion part 1 is matched with the fixing part 2. Specifically, the expansion part 1 is in threaded connection with the fixing part 2, so that the relative position of the expansion part 1 and the fixing part 2 can be conveniently adjusted through threaded rotation.
In a further embodiment of the present invention, the inner circumference of the expansion part 1 is coaxially provided with the seal ring 5, so that the abrasion of the expansion part 1 to the cable can be reduced.
In the present embodiment, the first swing plate 3 and the second swing plate 4 are configured symmetrically with respect to the center plane of the fixed portion 2. Therefore, the opening and closing part can be ensured to clamp the cable from two sides to exert force uniformly, so that the cable is clamped stably, and the cable is prevented from being bent at the junction of the fixed part 2 and the opening and closing part.
In the present embodiment, the first swing plate 3 and the second swing plate 4 are respectively attached to the fixed portion 2 by torsion springs 6. In this way, the pulling force of the first swing plate 3 and the second swing plate 4 so far is provided by the torsion spring 6, i.e., the resistance force against the expanding portion 1 to spread the first swing plate 3 and the second swing plate 4 is provided by the torsion spring 6. In a specific implementation, the first swinging plate 3 and the second swinging plate 4 can also be hinged with the fixed part 2 respectively, and the first swinging plate 3 and the second swinging plate 4 are connected through springs 7 positioned on two opposite sides of the fixed part 2, so that the first swinging plate 3 and the second swinging plate 4 are pulled to move in opposite directions through the springs 7.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to apply equivalents and modifications to the technical solution and the inventive concept thereof within the scope of the present invention.
