[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1 to 3 In an embodiment of the present invention, a cable tray for fixing cables includes a cable tray 1, the cable tray 1 includes a tray body 101, a through groove 102, and a fixed folding edge 103. The through groove 102 is opened at the top of the tray body 101 and penetrates to the top of the tray body 101. The fixed folding edges 103 are symmetrically fixed to the bottom of the tray body 101 and are distributed on both sides of the through groove 102.

[0029] A fixing component 2 is provided inside the bridge body 101 and the through slot 102, and the fixing component 2 is used to achieve fixed positioning of the cable;

[0030] The fixing assembly 2 includes a guide unit and a fixing unit;

[0031] The guide unit is used to provide pulling support and guidance for the installation of the cables inside the bridge body 101;

[0032] The fixing unit is used to limit and fix the laid cables;

[0033] The guide unit includes a fixed shaft 201 and a guide wheel 202;

[0034] The fixed shaft 201 is distributed between the two fixed folds 103 and is mutually engaged with the two fixed folds 103. The guide wheel 202 is rotatably connected to the inner side of the fixed shaft 201 and protrudes from the inner side of the bridge body 101 through the through slot 102.

[0035] The guide wheel 202 is used to form a support for the bottom of the cable, provide guidance for the movement of the cable and reduce the movement friction during the cable pulling and laying process;

[0036] The fixing unit includes a U-shaped seat 203, an arc-shaped pressing groove 204, a shrinkage notch 205, and a snap-on spring 206;

[0037] An arc-shaped pressing groove 204 is formed at the bottom of the vertical portion of the U-shaped seat 203, and contraction notches 205 are symmetrically formed on both sides of the horizontal portion of the U-shaped seat 203. One side of a snap-on spring 206 is fixed to the inner edge of the arc-shaped pressing groove 204, and the other side of the snap-on spring 206 is inclined and protrudes outward from the contraction notch 205.

[0038] Positioning slots 104 are provided on both sides of the outer wall of the bridge body 101 at positions aligned with the through slots 102;

[0039] The U-shaped seat 203 is clamped to the inner side of the bridge body 101 through the through groove 102 and is sleeved on the outer side of the guide wheel 202. The U-shaped seat 203 is clamped to the cable through the arc-shaped pressure groove 204, and is clamped to the inner side of the positioning groove 104 through the clamping spring 206 to realize the vertical limit locking of the U-shaped seat 203;

[0040] There are multiple guide wheels 202 evenly arranged along the straight direction of the fixed axis 201, and multiple arc-shaped pressing grooves 204 evenly arranged along the long side direction of the U-shaped seat 203, and the number and position of the arc-shaped pressing grooves 204 correspond to the number and position of the guide wheels 202 one by one.

[0041] In this embodiment, when the cable tray 1 is in use and the cable is laid, the bottom of the cable contacts the guide wheel 202. When the cable is pulled, the depression in the middle of the guide wheel 202 can guide the movement of the cable. At the same time, the guide wheel 202 can rotate along with the movement of the cable. This not only reduces the resistance to the movement of the cable, but also avoids friction between the cable and the tray body 101, making the installation of the cable easier.

[0042] After the cable is laid, the U-shaped seat 203 can be taken out and its opening facing downwards, and inserted into the top opening of the through slot 102. The U-shaped seat 203 is clamped to the outside of the cable through the arc-shaped pressing groove 204. The cable can be fixed by the friction resistance between the U-shaped seat 203 and the cable.

[0043] In addition, during this process, as the U-shaped seat 203 moves downward, the snap-on spring piece 206 contacts the inner wall of the bridge body 101 and is then forced to retract into the inside of the retracted notch 205. When the snap-on spring piece 206 is aligned with the positioning slot 104, the snap-on spring piece 206 is reset and snapped into the inside of the positioning slot 104 under the action of its own elastic force, thereby achieving the upper limit of the U-shaped seat 203 and then achieving the fixation of the U-shaped seat 203.

[0044] It should also be noted that the structural arrangement of the multiple guide wheels 202 allows the multiple cables to be pulled without interfering with each other, while achieving initial separation and limiting between the multiple cables. Subsequently, the multiple arc-shaped pressing grooves 204 are combined to separate and secure the multiple cables.

[0045] By using the above parts, multiple cables can be independently fixed inside the bridge body 101, which is convenient for later inspection and maintenance.

[0046] Please refer to Figures 1 to 3 There are multiple positioning slots 104 evenly arranged along the vertical direction, and two snap-on springs 206 are symmetrically arranged on the inner side of the shrinkage slot 205. An unlocking pressing piece 207 is fixed vertically upward and protruding from the top of the U-shaped seat 203 in the middle of the two snap-on springs 206.

[0047] In this embodiment, the plurality of positioning slots 104 can be provided to adapt to the positioning operation of cables with different diameters.

[0048] In addition, when the U-shaped seat 203 needs to be disassembled, it is only necessary to squeeze the U-shaped seat 203 downward to squeeze the cable into deformation, so that the U-shaped seat 203 and the card spring 206 move down slightly for a distance. At this time, there is a gap between the top of the card spring 206 and the positioning card slot 104. This gap provides space for the card spring 206 to rotate. At this time, the unlocking pressing piece 207 can be manually toggled to make the card spring 206 bend and deform and shrink to the inside of the shrinkage slot 205. In this way, the card spring 206 and the positioning card slot 104 are unlocked, and then the U-shaped seat 203 can be moved up and disassembled as a whole. The overall operation is simple and convenient.

[0049] Please refer to Figures 1 to 3 The bridge body 101, the through slot 102, the fixed folding edge 103, and the positioning slot 104 are integrally formed by punching and stamping processes;

[0050] The U-shaped seat 203 , the arc-shaped pressing groove 204 , the shrinkage notch 205 , the engaging spring 206 , and the unlocking pressing piece 207 are integrally formed by an injection molding process.

[0051] In this embodiment, the device can be conveniently produced and processed by the above process. It should also be noted that the entire material of the U-shaped seat 203 is an insulating material to ensure the safety of cable laying.

[0052] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
