[0019] The following detailed description provides various embodiments or examples for implementing the present invention. These are, of course, merely examples and are not intended to be limiting. Furthermore, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. This repetition is for simplicity and clarity in describing the present invention and does not imply a specific relationship between the various embodiments and / or configurations discussed.

[0020] like Figures 1-4A retractable cable tray shown includes a first cable tray 1 and a second cable tray 2 which are telescopically arranged at one end. The left and right sides of the first cable tray 1 are provided with slide grooves 3 extending forward and backward, and the left and right sides of the second cable tray 2 are provided with protrusions 4 sliding in the slide grooves 3. The relative sliding arrangement of the slide grooves 3 and the protrusions 4 facilitates the telescopic sliding of the first cable tray 1 and the second cable tray 2, thereby facilitating the adjustment operation.

[0021] Furthermore, a plurality of first through holes 5 are evenly spaced along the front-to-back direction on the slide groove 3, a plurality of second through holes 6 are evenly spaced and arranged equidistantly corresponding to the first through holes 5 on the raised portion 4, a spring piece 7 is also provided on the raised portion 4, a positioning flange 8 that can be ejected into the first through hole 5 is provided on the spring piece 7, and a self-tapping screw 9 is threadedly connected to the corresponding first through hole 5 and the second through hole 6.

[0022] During the installation operation, the positioning flange 8 on the spring piece 7 is ejected into the first through hole 5, so that the first bridge 1 and the second bridge 2 can be positioned to improve the stability during installation. In addition, when the appropriate position is adjusted, the self-tapping screws can be directly screwed into the corresponding first through hole 5 and the second through hole 6 to lock the first bridge 1 and the second bridge 2, so that the installation operation is simple, fast and efficient.

[0023] In addition, the first through hole 5 and the second through hole 6 can not only play the role of positioning and fixing, but also play the role of heat dissipation.

[0024] The spring piece 7 and the positioning flange 8 can be integrally formed by stamping the second bridge 2 .

[0025] Furthermore, the corners of the positioning flange 8 are arc-shaped structures, so that the positioning flange 8 can be easily inserted into or removed from the first through hole 5 .

[0026] See also Figure 1 、 Figure 2 、 Figure 4 As shown, fixing components for fixing cables are provided at the ends of the first bridge 1 and the second bridge 2 .

[0027] Furthermore, the fixing assembly includes columns 41 spaced apart on the left and right sides on the bottom wall of the first bridge 1 or the second bridge 2, and one or more fixing seats 42 for fixing cables are connected between the two columns 41. The fixing seats 42 are penetrated by wire holes 43 for allowing cables to pass through, so that the cables are fixed through the wire holes 43 to prevent the cables from being placed randomly in the bridge and affecting subsequent maintenance work.

[0028] Furthermore, the fixed seat 42 includes a lower seat 51 and an upper seat 52 which are inserted between the two columns 41. A plurality of first semi-circular grooves 53 are spaced apart on the upper end surface of the lower seat 51 along the left-right direction, and a plurality of second semi-circular grooves 54 corresponding to the first semi-circular grooves 53 are spaced apart on the lower end surface of the upper seat 52 along the left-right direction. The first semi-circular grooves 53 and the second semi-circular grooves 54 cooperate to form the threading hole 43.

[0029] When laying and installing the cable, first place a lower seat 51 on the column 41 for positioning, then place the cable in the first semi-circular arc groove 53 of the lower seat 51, and then place the upper seat 52 on the column 41, so that the cable is fixed by the cooperation of the second semi-circular arc groove 54 and the first semi-circular arc groove 53.

[0030] The outer wall of the column 41 is provided with an external thread, and a nut 61 is threadedly connected to the external thread.

[0031] The number of fixing seats 42 to be installed can be selected according to the number of cables, and finally, the fixing seats 42 can be fixed by screwing in the nuts 61 .

[0032] A screw 71 is provided at the lower end of the column 41 , and screw holes 72 threadably matched with the screw 71 are provided on the bottom walls of the first bridge 1 and the second bridge 2 . The structure is simple and the installation is convenient and quick.
