Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0019] The present application discloses an adjustable cable tray installation device, referring to Figure 1-3When the cable tray is installed, the two mounting plates 1 are fixedly connected to the building top of the installation area, and the bottom sides of the two mounting plates 1 are fixedly connected to a connecting sleeve 2, and the inner walls of the two connecting sleeves 2 are slidably connected to a connecting rod 3, and the bottom ends of the two connecting rods 3 are slidably connected to the same support rod 4. The internal rotation of the support rod 4 is connected with a two-way screw rod 5, and the two connecting rods 3 are spirally sleeved with the two-way screw rod 5, and the top side of the support rod 4 is placed in contact with the cable tray body 6; by setting the two-way screw rod 5, the size of the cable tray to be installed is measured, the two-way screw rod 5 is screwed, and the two-way screw rod 5 rotates, driving the two connecting rods 3 to move closer to each other until the spacing between the two connecting rods 3 is adapted to the size of the cable tray to be installed, and then the two mounting plates 1 are connected to the building top of the installation area with expansion bolts. After the connection is completed, the cable tray is placed on the support rod 4, thereby completing the installation of the cable tray. Compared with the installation method of tightening with bolts, it can meet the installation needs of cable trays of different sizes, reduce the limitations of use, and is conducive to popularization and use.

[0020] In the present application, two support plates 7 are hingedly connected to the front and rear sides of the support rod 4, and the top sides of the four support plates 7 are flush with the top side of the support rod 4; by setting the support plates 7, when the support plates 7 are flipped open, the four support plates 7 cooperate with each other to increase the contact area with the bottom side of the placed cable tray, thereby improving the stability of the cable tray when it is placed.

[0021] In this application, the outer sides of the two connecting sleeves 2 are threadedly connected with extrusion bolts 8, and the two extrusion bolts 8 are symmetrically distributed; by setting the extrusion bolts 8, when the position between the connecting sleeve 2 and the connecting rod 3 is adjusted, the extrusion bolts 8 can be used to limit the position between the adjusted connecting sleeve 2 and the connecting rod 3, so that the installation height position of the cable tray can be adjusted and fixed, thereby improving the scope of application.

[0022] In this application, the outer sides of the four support plates 7 are all threadedly connected with screw rods 9; by setting the screw rods 9, when the support plates 7 are flipped to the maximum flipping angle, the screw rods 9 are twisted inward to retract them, and the retracted screw rods 9 contact the side surfaces of the support rods 4, thereby limiting and fixing the flipped support plates 7.

[0023] In the present application, the top inner walls of the two connecting sleeves 2 are fixedly connected with springs 10, and the two springs 10 are respectively fixedly connected to the top sides of the two connecting rods 3; by setting the springs 10, the resilience of the springs 10 can be utilized to make the connecting rods 3 retract into the interior of the connecting sleeves 2 during carrying, thereby reducing the overall volume and achieving the purpose of convenient carrying.

The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0025] The implementation principle of the adjustable cable tray installation device of the embodiment of the present application is as follows: when in use, measure the size of the cable tray to be installed, screw the bidirectional screw rod 5, and when the bidirectional screw rod 5 rotates, it drives the two connecting rods 3 to move closer to each other until the distance between the two connecting rods 3 matches the size of the cable tray to be installed, and then connect the two mounting plates 1 to the building roof of the installation area with expansion bolts. After the connection is completed, the cable tray is placed on the support rod 4, thereby completing the installation of the cable tray. Compared with the installation method of tightening with bolts, it can meet the installation needs of cable trays of different sizes, reduce the limitations of use, and is conducive to popularization and use. When the support plate 7 is flipped open, the four support plates 7 cooperate with each other The contact area with the bottom side of the placed cable tray can be increased, thereby improving the stability of the cable tray when it is placed. After the position between the connecting sleeve 2 and the connecting rod 3 is adjusted, the extrusion bolt 8 can be used to limit the position between the adjusted connecting sleeve 2 and the connecting rod 3, so that the installation height position of the cable tray can be adjusted and fixed, thereby improving the scope of application. When the support plate 7 is flipped to the maximum flipping angle, the screw rod 9 is twisted inward to retract it. The retracted screw rod 9 contacts the side of the support rod 4, so that the flipped support plate 7 can be limited and fixed.
