Description

Technical Field

[0001] The utility model relates to the technical field of server cabinet protection, in particular to a computing cluster server cabinet wire harness anti-extrusion drag chain device. Background Art

[0002] Server cabinets are used to combine installation panels, plug-ins, plug-in boxes, electronic components, devices and mechanical parts and components to form an integral installation box. Server cabinets are composed of frames and covers. They generally have a rectangular shape and are placed on the ground. They provide an appropriate environment and safety protection for the normal operation of electronic equipment. Drag chains, also known as wire and cable protection drag chains, are devices that restrain cables or wires or air and hydraulic pipes to facilitate their rotation and movement. The wiring harnesses inside the cabinet are usually messy, so drag chains are needed to optimize the placement of the wiring harnesses.

[0003] For example, a Chinese utility model patent with announcement number CN217904872U discloses a server cabinet with a wire harness anti-falling function. Although the above-mentioned prior art reduces the falling off of the external connection wire harness during use, reduces the poor contact phenomenon of the server cabinet, and reduces indirect losses, during the use of the server cabinet, many servers will be placed inside a cabinet, which will result in a large number of wire harnesses inside the cabinet, and most of the wire harnesses will be tangled together. When multiple wire harnesses are tangled together, as long as there is a slight shake, part of the wire harness will squeeze other wire harnesses, and the squeezed wire harness will be forced to pull, which can easily lead to loose interfaces and poor contact of the server. Therefore, it is necessary to design a computing cluster server cabinet wire harness anti-extrusion drag chain device. Utility Model Content

[0004] In order to solve the technical problem that a large number of wire harnesses are entangled together inside the cabinet, and the shaking of some wire harnesses will squeeze other wire harnesses, causing the connections of the squeezed wire harnesses to loosen easily and cause poor contact, the utility model provides a computing cluster server cabinet wire harness anti-extrusion drag chain device.

[0005] The utility model is implemented by the following technical scheme: a computing cluster server cabinet wire harness anti-extrusion drag chain device, including a service cabinet, a computer server is arranged inside the service cabinet, one side of the computer server is electrically connected to the wire harness, the outer sleeve of the wire harness is provided with a drag chain to prevent the wire harness from being squeezed, both ends of the drag chain are provided with fixing components that allow the drag chain to be arbitrarily fixed at any position on the wire harness, and one side of each of the fixing components is provided with an installation component for installing the fixing component on the drag chain.

[0006] Through the above technical solution, the drag chain is put on the wire harness, and the fixing component is fixed at any position of the wire harness using the installation component. This can not only save the internal space of the cabinet, but also straighten the wire harness to prevent it from being squeezed.

[0007] As a further improvement of the above scheme, the fixing assembly includes two clamping blocks arranged on the circumferential surface of the wiring harness, a pushing column fixedly installed on one side of each clamping block, and a mounting plate slidably mounted on each pushing column, a rotating column fixedly installed on one side of each mounting plate, and a base rotatably installed on one side of each rotating column.

[0008] Through the above technical solution, the two clamping blocks can clamp the wire harness, allowing the drag chain to be installed at any position of the wire harness.

[0009] As a further improvement of the above scheme, a first limit block is fixedly installed at one end of each push column, a first push spring is sleeved on each push column, one end of which is fixedly installed with an adjacent clamping block and the other end is fixedly installed with an adjacent mounting plate, and a rubber strip is fixedly installed on one side of each clamping block.

[0010] Through the above technical solution, the first push spring pushes the clamping block to clamp the wire harness.

[0011] As a further improvement of the above scheme, the installation assembly includes clamping blocks arranged on both sides of each base, two limit rods fixedly installed on one side of each clamping block, and a limiting plate arranged on one side of each clamping block, and each of the limiting plates is slidably sleeved with an adjacent limit rod.

[0012] Through the above technical solution, the two clamps can clamp the base so that the base can be removed from the drag chain.

[0013] As a further improvement of the above solution, a fixing groove matched with the base is provided on one side of each clamping block.

[0014] Through the above technical solution, the clamping block cooperates with the fixing groove to completely fix the base.

[0015] As a further improvement of the above solution, each of the limit rods is sleeved with a second push spring with one end fixedly mounted to the adjacent clamping block and the other end fixedly mounted to the adjacent limiting plate, and one end of each limit rod is fixedly mounted with a second limit block.

[0016] Through the above technical solution, the second push spring pushes the clamping block to prevent the base from loosening.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a drag chain, a fixing component and an installation component, wherein the drag chain is sleeved on the wire harness, the fixing component is fixed by the installation component, and the wire harness is slid to the position where the wire harness needs to be protected and the fixing component is clamped on the wire harness, so that the drag chain can only protect the required position and avoid the drag chain occupying a large amount of space inside the cabinet. This arrangement can not only arrange the wire harness neatly, but also avoid poor contact caused by squeezing between the wire harnesses. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] Please combine Figure 1-Figure 3 A computing cluster server cabinet wire harness anti-extrusion drag chain device of the present embodiment includes a service cabinet 1, a computer server 2 is arranged inside the service cabinet 1, a wire harness 3 is electrically connected to one side of the computer server 2, a drag chain 4 is arranged on the outside of the wire harness 3 to prevent the wire harness 3 from being squeezed, and both ends of the drag chain 4 are provided with fixing components that allow the drag chain 4 to be arbitrarily fixed at any position on the wire harness 3, and one side of each fixing component is provided with an installation component for installing the fixing component on the drag chain 4.

[0026] Combination Figure 2 and Figure 3The fixing component includes two clamping blocks 501 arranged on the circumferential surface of the wiring harness 3, a pushing column 502 fixedly installed on one side of each clamping block 501 and a mounting plate 503 slidably mounted on each pushing column 502, a rotating column 7 is fixedly installed on one side of each mounting plate 503, a base 8 is rotatably installed on one side of each rotating column 7, a first limit block 9 is fixedly installed on one end of each pushing column 502, and a first pushing spring 10 is sleeved on each pushing column 502, one end of which is fixedly installed with the adjacent clamping block 501 and the other end is fixedly installed with the adjacent mounting plate 503, and a rubber strip 11 is fixedly installed on one side of each clamping block 501. The two clamping blocks 501 can clamp the wiring harness 3, so that the drag chain 4 can be mounted at any position of the wiring harness 3.

[0027] Combination Figure 2 and Figure 3 The installation assembly includes clamping blocks 601 arranged on both sides of each base 8, two limit rods 602 fixedly installed on one side of each clamping block 601, and a limiting plate 603 arranged on one side of each clamping block 601. Each limiting plate 603 is slidably sleeved with the adjacent limit rod 602. A fixing groove adapted to the base 8 is opened on one side of each clamping block 601. Each limit rod 602 is sleeved with a second push spring 12 with one end fixedly installed with the adjacent clamping block 601 and the other end fixedly installed with the adjacent limit plate 603. A second limit block is fixedly installed at one end of each limit rod 602. The second push spring 12 pushes the clamping block 601 to prevent the base 8 from loosening.

[0028] The implementation principle of a computing cluster server cabinet wiring harness anti-extrusion drag chain device in the embodiment of the present application is: when the wiring harness 3 inside the service cabinet 1 is large and relatively messy, the drag chain 4 is set on the wiring harness 3, and the base 8 is slid between the two clamping blocks 601. The second push spring 12 will push the clamping block 601 to cooperate with the fixing groove to fix the base 8, so that the pushing column 502 can be pulled to clamp the clamping block 501 in cooperation with the rubber strip 11 to clamp the wiring harness 3. This setting allows the drag chain 4 to be moved to the place where the wiring harness 3 needs to be protected, preventing it from occupying too much internal space of the service cabinet 1, and the wiring harness 3 can be arranged neatly, and the wiring harness 3 can be prevented from being squeezed and causing poor contact.

[0029] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
