Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and in particular to a lockable flip-top cable tray. Background Technology

[0002] In data center server rooms, cable trays are typically installed on the ceiling to ensure the standardized laying and safe protection of multiple sets of cables. Among these, trough-type cable trays are widely used due to their good sealing and strong protection. Existing trough-type cable trays mainly consist of two parts: a U-shaped trough and a cover plate. During installation, the U-shaped trough is first fixed to the ceiling using brackets, and then the cover plate is slid in along the slide rail at the top of the U-shaped trough to achieve enclosed protection for the cables.

[0003] However, in actual operation and maintenance, it was found that this structure has obvious inconveniences in cable inspection and maintenance scenarios: when it is necessary to troubleshoot, adjust the line or perform routine maintenance on the cables inside the cable tray, the staff needs to pull the cover plate completely out from one end (or side) of the trough-type cable tray. At this time, if the cable tray is long, pulling out the cover plate not only requires a large operating space, but may also require multiple people to work together; after the maintenance is completed, the cover plate needs to be realigned with the slide rail of the U-shaped channel and gradually pushed back to its original position from one end. If there is dust or slight deformation in the slide rail, the sliding posture of the cover plate needs to be repeatedly adjusted. This "pull-out" cover plate design increases the overall maintenance time and reduces maintenance efficiency. Especially when the computer room urgently needs to deal with cable faults, the troubleshooting progress may be delayed due to the cumbersome disassembly and assembly of the cover plate. Utility Model Content

[0004] This utility model provides a lockable flip-top cable tray to solve the defects of existing pull-out cable tray covers that are inconvenient to operate due to factors such as obstructed slide rails and cable tray length.

[0015] The lockable flip-top cable tray provided by this utility model achieves flip-top rotation around the top edge of the first longitudinal side plate through a flip-top connection between the flip-top and the first longitudinal side plate. When workers need to troubleshoot, adjust lines, or perform routine maintenance, they can open the flip-top to access the cables inside the cable tray.

Therefore, they should not be construed as limitations on the embodiments of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection, wherein a fixed connection can include an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this utility model based on the specific circumstances.

[0027] In this embodiment of the utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0028] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0029] The following is combined Figures 1 to 6 This invention describes a lockable flip-top cable tray (hereinafter referred to as "cable tray").

[0030] Cable trays are devices used to house and protect cables. They need to extend along with the cables. Therefore, the direction in which cable trays follow the cable routing / extension can be called the longitudinal direction of the cable tray.

[0031] Figure 1 This is a perspective view of the lockable flip-top cable tray provided by this utility model, as shown below. Figure 1 As shown, the cable tray includes a U-shaped trough 1, a flip cover 4, and a locking mechanism 5.

[0032] From a perspective perpendicular to the longitudinal direction, the U-shaped trough 1 has a base plate and a first longitudinal side plate 2 and a second longitudinal side plate 3 arranged opposite to each other. The flip cover 4 is foldably connected to the first longitudinal side plate 2. Thus, the side edge of the flip cover 4 connected to the first longitudinal side plate 2 can be called the flip side edge, and the side edge of the flip cover 4 opposite to the flip side edge can be called the free side edge.

[0033] It is conceivable that the cables requiring cabling in data center server rooms are quite long. If the cable trays used for this purpose were a single piece, it would pose certain obstacles to the cabling design, manufacturing, transportation, and assembly of the cable trays. Therefore, cable trays are designed with a segmented structure, with each segment having a U-shaped trough 1 and a flip cover 4 of a similar length. This structure facilitates the routing and installation of cables and even the cable trays themselves within the server room.

[0034] The locking mechanism 5 includes a locking male component and a locking female component that cooperate with each other. One of them, for example, the locking female component, is located at the top of the second longitudinal side plate 3, while the other of them, for example, the locking male component, is located at the free side edge of the flip cover 4; or vice versa. Thus, when the flip cover 4 is flipped to its closed position, the locking male component and the locking female component cooperate with each other to lock the cable tray in a closed state.

[0035] By connecting the flip cover 4 to the first longitudinal side plate 2 in a flip-up manner, the flip cover 4 can be flipped around the top edge of the first longitudinal side plate 2. When the staff needs to troubleshoot, adjust the line or perform routine maintenance, they can open the flip cover 4 in a flip-up manner to access the cables inside the cable tray. Similarly, after the staff has completed the relevant work, the flip cover 4 can be closed in a flip-up manner. Compared with the operation of the pull-out cover in the prior art, this configuration significantly saves the staff's work time and improves the ease of operation of the flip cover 4.

[0036] Furthermore, by setting the locking mechanism 5, when the cable tray is in a routine operating state that does not require inspection, adjustment or maintenance, the locking mechanism 5 will lock the flip cover 4 and the U-shaped trough frame 1 in a closed state, providing comprehensive and reliable protection for the cables in the cable tray, so as to prevent dust or other impurities in the environment from accumulating on the cables, and at the same time prevent the cables from being damaged by external intrusive substances.

[0037] Figure 2 yes Figure 1 The image shown is a perspective view of the lockable flip-top cable tray in its open position. Figure 3 yes Figure 2 The enlarged view of detail A of the lockable flip-top cable tray shown. Figure 4 yes Figure 2 An enlarged view of detail B of the lockable flip-top cable tray is shown, as... Figures 2 to 4 As shown, the locking male component is a pin 6 that is linearly movable along the longitudinal direction, and the locking female component is a positioning plate 7 orthogonal to the longitudinal direction. The positioning plate 7 has a pin hole 8 that allows the pin 6 to pass through. When the pin 6 passes through the pin hole 8, the locking mechanism 5 is in the activated state, and the relative positional relationship between the flip cover 4 and the second longitudinal side plate 3 is locked. In this state, the flip cover 4 cannot be opened. Preferably, the pin 6 is designed as a latch with a bevel. With the cooperation of the bevel and the pin hole 8 and the guide hole 13, it is easier to pass through the pin hole 8 and the guide hole 13. The description of the guide hole 13 will be presented below.

[0038] Furthermore, the locking mechanism 5 may include more than one set of locking male components and locking female components. As mentioned above, the cable tray, i.e., the U-shaped trough 1 and the flip cover 4, both have a certain length. The locking mechanism 5 may include one, two or more sets. For example, in the case of two sets of locking male components and locking female components, the two sets of locking male components and locking female components are arranged back to back on each other in the longitudinal central section of the cable tray, or other similar arrangements.

[0039] Furthermore, each locking component also includes a first reference plate 9, a second reference plate 10, a guide rod 11, and a slider 12. On the U-shaped cable tray 1 or the flip cover 4, the first reference plate 9 and the second reference plate 10 are arranged parallel to each other along the longitudinal direction of the cable tray, and are spaced a certain distance apart. The guide rod 11 extends longitudinally along the cable tray, with its two ends connected to the first reference plate 9 and the second reference plate 10, respectively. In this embodiment, there are two guide rods 11; however, other configurations are also possible. The slider 12 is fitted onto the guide rod 11 and is slidable along the guide rod 11; in other words, the sliding stroke of the slider 12 is between the first reference plate 9 and the second reference plate 10. A pin 6 is fixedly connected to the slider 12, thereby allowing the pin 6 to slide along the guide rod 11 together with the slider 12. The second reference plate 10 has a guide hole 13 that allows the pin 6 to pass through, so that when the slider 12 slides to contact the second reference plate 10, the pin 6 extends outward through the guide hole 13 and finally inserts into / passes through the pin hole 8 of the positioning plate 7.

[0040] Furthermore, the locking component also includes an elastic element 14, such as a spring, which is sleeved on the guide rod 11 and connected between the first reference plate 9 and the slider 12. Thus, when the slider 12 moves to a position close to the first reference plate 9, the elastic element 14 is compressed, thereby applying a repulsive force to the first reference plate 9 and the slider 12 respectively; when the slider 12 is released by the operator, since the first reference plate 9 is fixed, the slider 12 is pushed towards the second reference plate 10 under the repulsive force applied by the elastic element 14, ultimately causing the pin 6 to pass through the guide hole 13 and the pin hole 8.

[0041] The advantage of this configuration is that all actions of locking the male component do not necessarily rely on manual operation. Moving the slider 12 to a position close to the first reference plate 9 requires manual or other methods; however, once the slider 12 is released, its return to contact with the second reference plate 10 is performed automatically by the elastic element 14 without manual intervention. This simplifies the operational steps required by the operator to a certain extent.

[0042] Furthermore, the guide rod 11 is threadedly connected to the first reference plate 9, and the guide rod 11 passes through the second reference plate 10, with a manual knob 16 provided at its end where it passes through the second reference plate 10. Specifically, the first end of the guide rod 11 connected to the first reference plate 9 has an external thread, and a threaded hole 15 is provided at the corresponding position on the first reference plate 9, thereby achieving a threaded connection between the guide rod 11 and the first reference plate 9. On the other hand, the second reference plate 10 has a through hole (not shown in the figure) corresponding to the guide rod 11, through which the second end of the guide rod 11 passes and extends outward. A manual knob 16 is provided at the second end of the guide rod 11, allowing the operator to adjust the degree of threaded connection between the guide rod 11 and the first reference plate 9 by rotating the guide rod 11 manually.

[0043] Furthermore, the slider 12 is provided with an operating part 17 that protrudes outward relative to the U-shaped slot frame 1 or the flip cover 4. The advantage of this configuration is that when the slider 12 needs to be moved to a position close to the first reference plate 9, the operator can grasp the operating part 17 to move the slider 12, rather than grasping the slider 12 body, which is relatively more difficult to access.

[0044] Figure 5 This is a perspective view of the lockable flip-top cable tray provided by this utility model from a rear viewpoint, as shown below. Figure 5 As shown, the flip-up side edge of the flip cover 4 is connected to the top of the first longitudinal side plate 2 via a damping pivot 18.

[0045] The advantage of this configuration is that when the operator opens the flip cover 4, the flip cover 4 can be suspended at any angle relative to the first longitudinal side plate 2 with the help of the damping pivot 18, instead of the usual pivot, where the operator has to rotate the flip cover 4 more than 90° so that it can rest against the suspension bracket or hang down by its own weight.

[0046] Figure 6 This is a perspective view of the lockable flip-top cable tray provided by this utility model from a bottom angle, as shown below. Figure 6 As shown, the base plate has a plurality of first connecting holes 19, which are arranged along the longitudinal and width directions. Specifically, the first connecting holes 19 are arranged at equal intervals along the longitudinal and width directions, thereby forming a first connecting hole array.

[0047] The cable tray also includes a U-shaped hanger 20, which includes a crossbeam 21. The length of the crossbeam 21 is designed to be greater than the width of the U-shaped trough. The crossbeam 21 is provided with a plurality of second connecting holes 22, which are aligned one by one with the first connecting holes 19 arranged in a row in the width direction. Thus, external connectors can be used to simultaneously pass through the corresponding second connecting holes 22 and first connecting holes 19 to connect the U-shaped hanger 20 to the U-shaped trough 1.

[0048] With the above configuration, the U-shaped cable tray 1, especially its base plate, can be connected to the U-shaped hanger 20 at any section in its longitudinal direction, which is conducive to the rational layout of the connection position of the U-shaped hanger 20 relative to the U-shaped cable tray 1, thereby rationally distributing the load distribution of the cable and the U-shaped cable tray 1.

[0049] Furthermore, the U-shaped hanger 20 also includes a pair of vertical rods 23, the top of each vertical rod 23 being configured to be fixedly connected to the wall of the data center. For example, each vertical rod 23 has a mounting hole at its top, and expansion bolts are applied to the wall of the data center, such as the ceiling, and then the mounting holes are connected to the expansion bolts, thereby fixing the cable tray to the wall of the data center.

[0050] Furthermore, the U-shaped hanger 20 can be either integrally formed or manufactured separately as crossbeams 21 and vertical rods 23 and then assembled on-site. In the case where the U-shaped hanger 20 is manufactured separately and then assembled, the crossbeams 21 and vertical rods 23 can be connected using suitable methods, such as bolting, welding, or other similar methods.

[0051] Reference Figure 2 The U-shaped cable tray 1 has a plurality of rollers 24 arranged longitudinally, each roller 24 extending in the width direction. Specifically, these rollers 24 are arranged longitudinally at equal intervals. Preferably, these rollers 24 are not directly connected to the first longitudinal side plate 2 and the second longitudinal side plate 3; instead, a support plate 25 is provided at a certain height above the bottom plate within the U-shaped cable tray 1, and this support plate 25 is hollow, with the rollers 24 arranged in the hollow portion of the support plate 25. During cable laying or adjustment work, when workers pull the cable, the friction between the cable and the rollers 24 causes the rollers 24 to rotate, thereby preventing cable damage. Furthermore, the rollers 24 can suspend the laid cable within the U-shaped cable tray 1, and the gaps between adjacent rollers 24 facilitate heat dissipation from the cable.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
