[0038] The present invention provides a multi-functional cable tray.

[0039] Before the detailed introduction, it should be understood that there are many application scenarios for the present utility model. As a kind of trough-type cable tray, it is a trough-type component made by bending a whole steel plate or formed integrally by pouring. The trough-type cable tray has a certain depth and is closed. Therefore, it can be used for fully enclosed cable laying. It is most suitable for laying computer cables, communication cables, thermocouple cables and control cables of other highly sensitive systems. It has good effects on shielding interference of control cables and protecting cables in highly corrosive environments.

[0040] The following further details the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0041] As Figure 1-3 shown, it is a schematic diagram of the first embodiment of the present utility model. As Figure 4-7 shown, it is a schematic diagram of the second embodiment of the present utility model.

[0042] The open box body 3 has an enclosing structure. The enclosing structure can be square as Figure 1 shown, or pentagonal as Figure 4 shown, or can be set into other shapes according to needs. A cavity 15 is formed inside the enclosing structure. The cavity 15 is used to accommodate cables. The open box body 3 extends along a first direction; the first direction here can be any direction, just for distinction from other directions. The limit card slots 4 are oppositely arranged at the opening of the open box body 3 and extend along the first direction to form strip-shaped chutes; the panel 1 has a width adapted to the opening of the open box body 3 and a length extending along the first direction, and is detachably covered with the open box body 3; the upper clamping parts 2 are arranged at both ends of the panel 1, and the length of the upper clamping parts 2 extends along the first direction to form sliding strips. The panel 1 and the open box body 3 are slidably connected through the sliding strips and the strip-shaped chutes; the positioning holes 14 are arranged at the bottom or side of the open box body 3 and are used to fix the open box body to a building or structure through fixing parts such as screws or nuts.

[0043] Generally speaking, the shape design of the open box body 3 is different according to different usage scenarios. If it is used in a large space, such as outdoors or on an indoor wall, a square shape is generally selected. However, if it is set at the corner of a wall or at the connection of a wall and a top wall or a ground, or in a place where space needs to be saved, a square shape will have a corner protruding outside the wall, with low safety and being more prone to damage. At this time, a special-shaped one needs to be set, such as the design with a pentagonal cross-section proposed in the second embodiment. This shape has a first right angle, a second right angle and a third right angle. The second right angle is adjacent to the first right angle, and the second right angle is opposite to the third right angle. During installation, the first right angle is close to the internal corner of the wall. It not only saves space, improves safety, but also increases the visible range of the socket panel 9 arranged on the panel 3, and can improve the convenience of use.

[0044] Furthermore, the size of the opening of the open box body 3 should match the width of the socket panel 9; the size of the cavity 15 of the open box body 3 should not only be able to accommodate the passing cable, but also be able to accommodate the internal components of the socket panel 9. The setting of the socket panel 9 expands the use of the cable tray, increasing the function of the power output end from a cable line maintenance structure. Of course, a valve for controlling the on / off of this section of the cable can also be set on the socket panel 9 to facilitate later maintenance, replacement and other work.

[0045] It should be noted that the panel 1 is detachably covered on the open box body 3, specifically through the cooperation of the upper clamping portion 2 and the limit card slot 4. The upper clamping portion 2 of the panel 1 can be directly pressed into the limit card slot 4 of the open box body 3, or can be inserted into the limit card slot 4 from the end through the strip-shaped sliding groove extended from the limit card slot 4, and adjusted to the required position by pulling.

[0046] Generally speaking, multiple positioning holes 14 are provided. And in the case of the second embodiment, they need to be provided on both adjacent sides against the wall to improve stability. In the installation of the cable tray, small-sized cable trays are generally horizontally hoisted, that is, the cable tray is lifted by a hanging frame. At this time, the positioning holes 14 are provided on the opposite side walls of the open box body 3; if it is a larger-sized cable tray, it is often horizontally hoisted, that is, the cable tray is lifted by a cross arm, and then fixed by screw rods on both sides of the cross arm. At this time, the positioning holes 14 can be provided or not; if it is a horizontal situation against the wall, it is generally suitable for horizontal hoisting, that is, using a bracket, and at this time the positioning holes 14 are adapted to the through holes of the bracket.

[0047] Furthermore, a T-shaped chuck 6 is provided on the inner side wall of the open box body 3, and the socket panel 9 is fixed at the opening of the open box body 3 through the chuck 10 and the connecting column 11. If multiple T-shaped chucks 6 are provided, a positioning groove 5 can be formed between every two T-shaped chucks 6 for positioning cable lines and cable line groups. It should be noted that the lines in the cable tray are generally multi-channel, such as communication cables, power cables, lighting cables, etc., and they need to be grouped in the cable tray. At this time, multiple positioning grooves 5 can achieve this function.

[0048] Even further, in order to separate scattered or particularly important lines, a number of fixing rings 7 are provided on the inner side wall of the open box body 3, and the fixing rings 7 have notches. The electric wires can be clamped into the fixing rings 7 through the notches. The extending direction of the fixing rings 7 is parallel to the first direction, and its extension can be continuous or intermittent, as long as it can fix the electric wires.

[0049] It should be noted that if the fixed ring 7 is arranged at multiple vertices of the inner side wall of the open box body 3, the distance between the electric wires is maximized. Different cable lines generate different magnetic fields and heat during operation. If they are too close, they will have mutual influence and it is not conducive to heat dissipation. Positioning them at the maximum distance can reduce the mutual influence and is also conducive to heat dissipation.

[0050] Furthermore, the connection between the panel 1 and the open box body 3 is a snap connection, that is, the end of the upper snap portion 2 is provided with an upper snap hook 16, and the lower snap hook 12 is provided at the opening of the open box body 3. The upper snap hook 16 and the lower snap hook 12 are snapped together to prevent the slide bar from detaching from the strip-shaped chute.

[0051] It should be pointed out that in order to facilitate the upper snap hook 16 to enter the chute, the hook head portion of the lower snap hook 12 bends towards the cavity 15. The lower snap hook 12 has an inner arc surface and an outer arc surface. The outer arc surface can reduce the friction between the upper snap hook 16 and the lower snap hook 12 when pressed, and the inner arc surface is conducive to forming a snap connection with the lower snap hook 12.

[0052] Even further, in order to limit the upper snap portion 2, the positive section of the limit card slot 4 is U-shaped, one end is connected to the open box body 3, and the other end is provided with an abutting portion 13 to abut against the upper snap portion 2. Further limiting the upper snap hook 16 through the abutting portion 13 is conducive to improving the stability of the snap connection.

[0053] It should be noted that another embodiment of the limit card slot 4 is also proposed in the present utility model, that is, the limit card slot 4 is a strip-shaped chute with an inner arc in the positive section. Correspondingly, the upper snap portion 2 is provided with a cylinder adapted thereto. The cylindrical cavity with a notch is a thin shell with certain plasticity and resilience, so that when snap-connected, the cylinder of the upper snap portion 2 is pressed into the limit card slot 4 through the notch. Preferably, the distance between the connection lines of the two end points of the inner arc is between the radius r and the diameter D of the cylinder. Applying pressure to the cylinder can stretch the arc surface so that the cylinder can be snapped into the limit card slot 4; when the cylinder is snapped into the limit card slot 4, the notch returns to its initial size to lock the cylinder.

[0054] It should be noted that in practical applications, end caps 8 need to be provided at both ends of the cylinder formed by the covering of the open box body 3 and the panel 1 to turn the cable tray into a closed mechanism, thereby improving its protection performance. Through holes (not shown in the figure) can be provided on the end cap 8 or the open box body 3 to allow the cable to pass through.

[0055] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
