Description

Technical Field

[0001] The utility model relates to the technical field of cable installation equipment, in particular to a multi-layer U-shaped steel wiring rack. Background Art

[0002] The cable tray, also known as the cable bridge, is a device used for cable routing in the computer room. It is mainly used to support, hang and classify different types of cables, such as power cables, network cables, optical cables, etc. Cables are arranged at different heights according to different cable types, so that the cables are neatly arranged, which is convenient for subsequent maintenance and replacement, and meets the environmental requirements of modern data centers. Most of the existing cable trays are single-layer cables, which mix strong electricity, weak electricity and optical cables in the same cable duct, making it extremely inconvenient to distinguish and repair, and easy to interfere with each other. Secondly, when the cables are placed in the cable duct, they are only distinguished and classified by bundling, which is easy to confuse after multiple maintenance, so it needs to be improved.

[0012] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0013] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0015] like Figures 1-2As shown, a multi-layer U-shaped steel wiring rack includes a skeleton 1, a bottom groove 2, a middle groove 3 and a surface groove 4. The skeleton 1 is U-shaped, and the bottom groove 2, the middle groove 3 and the surface groove 4 are arranged in sequence from low to high in the skeleton 1. One side of the middle groove 3 and the surface groove 4 is hinged to the inner wall of the skeleton 1, specifically through a hinge connection, so that the middle groove 3 and the surface groove 4 can be rotated conveniently to organize the cables in the bottom groove 2. The other side of the middle groove 3 and the surface groove 4 is clamped with the inner wall of the frame 1. A plurality of pressing rollers 41 are arranged in the surface groove 4. The bottom of the bottom groove 2 and the middle groove 3 are both provided with a plurality of parallel and spaced slide grooves 21. The slide grooves 21 are arranged along the extension direction of the bottom groove 2 and the middle groove 3. The slide groove 21 is movably clamped with a limit member 5. The limit member 5 includes a stopper 51, a latch 52 and a spring 53. The stopper 51 is in an inverted T shape. The bottom of the stopper 51 is hollow. Two latches 52 are relatively movably plugged into the bottom of the stopper 51 and connected by a spring 53. Specifically, in the present embodiment, the frame 1 is made of stainless steel, the bottom groove 2, the middle groove 3 and the surface groove 4 are made of aluminum alloy, and the stainless steel frame 1 is fixed or hoisted on the wall with bolts or latches to ensure that the structural strength meets the standards. The bottom groove 2, the middle groove 3 and the surface groove 4 are stacked in three layers. The bottom groove 2 is used for the strong wire harness, the middle groove 3 is used for the weak wire harness, and the surface groove 4 is used for the optical cable. They are classified to prevent confusion between the three harnesses and signal interference between each other. At the same time, we have installed a wire pressing roller 41 in the surface groove 4 to press the optical cable running in the surface groove 4. In order to prevent entanglement, we use a limiter 5 to separate the cables in the bottom groove 2 and the middle groove 3. The limiter 5 is movably connected to the slide groove 21, so that the limiter 5 can move along the slide groove 21 to adjust the position, and then adjust the distance between the two limiters 5 to ensure that the cables can be separated at equal distances. The stopper 5 includes a stopper 51, a latch 52 and a spring 53. The two latches 52 are movably plugged into the bottom of the stopper 51. The ends of the latches 52 protrude from the stopper 51 under the action of the spring 53 and abut against the inner wall of the slide 21. The stopper 5 is positioned in the slide 21 by using the friction force generated at the abutment between the ends of the latches 52 and the slide 21. When the position of the stopper 5 is to be adjusted, the spring 53 is compressed, the latch 52 is retracted into the stopper 51, and the maintenance personnel can continue to slide the stopper 5 along the slide 21 to move it to the designated position. The stopper 5 can be used to separate the wire harnesses in the bottom slot 2 or the middle slot 3 to prevent the wire harnesses from being confused and tangled. The position of the stopper is adjustable, and it can be moved to the designated position, which makes it more convenient to separate the wire harnesses.

[0016] like Figure 2As shown, the bottom of the stopper 51 is provided with a through hole 511, and the adjacent ends of the two latches 52 protrude from the through hole 511. Specifically, the latches 52 are L-shaped, and the adjacent ends thereof protrude from the through hole 511 at the bottom of the stopper 51. The operator can compress the spring 53 through the ends of the two latches 52 that leak out, so that the ends of the latches 52 are separated from the inner wall of the slide groove 21. At this time, the entire limiter 5 can be slid. When the limiter 5 moves to the specified position, the force applied to the latches 52 is released, and the spring 53 recovers from the compressed state, and the ends of the latches 52 that are away from each other can be re-contacted with the inner wall of the slide groove 21, and then clamped, and the limiter 5 can be fixed at this time.

[0017] Specifically, the inner wall of the slide groove 21 is serrated, and cooperates with the latch 52 to fix the position of the positioning stopper 51 .

[0018] Specifically, a rubber pad is adhered to the side of the stopper 51, which is flexible when in contact with the cable to avoid scratching the cable, causing damage to the cable sheath and signal leakage.

[0019] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
