DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a steel cage support frame comprises three bases 1, a telescopic mechanism 2 is installed between the three bases 1, an adjusting mechanism 3 is installed on the top of the base 1, the telescopic mechanism 2 comprises four connecting rods 4, the four connecting rods 4 are movably installed on the inner sides of the two bases 1 located at the front and rear ends respectively, a hinge 5 is installed between one end of each connecting rod 4 and the base 1, and a clamping column 6 is installed on the other end of the connecting rod 4, two guide rails 7 are installed on the front and rear parts of the middle base 1, and sliding grooves 8 are provided on the inner sides of the two guide rails 7, buckles 9 are movably installed on both sides of the top of the middle base 1, and a positioning column 10 is installed on the outer end of the bottom of the buckle 9, positioning holes 11 are opened on both sides of the top of the two bases 1 located at the front and rear ends, fixing blocks 12 are fixedly installed on both sides of the bottom of the two bases 1 located at the front and rear ends, and rollers 13 are movably installed on both sides of the bottom of the middle base 1.

[0023] In this embodiment, the three bases 1 are arranged in the same horizontal line, and the connecting rod 4 is movably connected to the base 1 through the hinge 5. Each base 1 is connected to each other through the connecting rod 4, which is convenient for unfolding and folding.

[0024] In this embodiment, the upper and lower ends of the clamping column 6 are respectively located in two slide grooves 8 and are slidably arranged. The connecting rod 4 is located between the two guide rails 7 and is matched with each other. One end of the connecting rod 4 is connected to the two bases 1 located at the front and rear ends. The clamping column 6 slides in the slide groove 8, so that the two bases 1 located at the front and rear ends are connected to the base 1 located in the middle.

[0025] In this embodiment, the buckle 9 is located at the top of the middle base 1 and is movably rotatable. The positioning column 10 is snap-connected with the positioning hole 11. The positioning column 10 is snapped into the positioning hole 11, so that the three bases 1 can be fixed to each other after storage.

[0026] In this embodiment, the adjustment mechanism 3 includes three groups of support seats 14, which are movably installed on the tops of the three bases 1 respectively. Screws 15 are movably installed on both sides of the support seats 14 near the bottom and located inside the base 1. A turntable 16 is fixedly installed at one end of the screw 15. Positioning rods 17 are movably installed on both sides of the support seats 14 near the top. A knob 18 is fixedly installed on the outer end of the positioning rod 17. The support seats 14 are slid by the screws 15 to facilitate adjustment and support of steel cages with different diameters.

[0027] In this embodiment, the support seat 14 and the screw rod 15 are threadedly connected, and the threads at both ends of the outer periphery of the screw rod 15 are in opposite directions. The support seat 14 slides through the threads of the screw rod 15 to facilitate adjustment of different diameters.

[0028] In this embodiment, there are two support seats 14 in each group, and the two support seats 14 in each group are symmetrically arranged. The positioning rod 17 passes through both sides of the support seat 14 and is threadedly connected. By adjusting the positioning rod 17, the steel cage is positioned on the support seat 14, which is convenient for fixing and taking and placing.

[0029] It should be noted that the utility model is a steel cage support frame. When in use, the three bases 1 are first unfolded. By pulling one of the bases 1, the clamping column 6 of the connecting rod 4 is located in the slide groove 8 and slides outward, and is rotated and unfolded by the hinge 5. At the same time, the base 1 in the middle slides on the ground through the roller 13. When the three bases 1 are stretched to a certain distance, the positioning column 10 of the connecting rod 4 slides to the two ends of the slide groove 8, and is fixed by the friction between the fixing blocks 12 at the bottom of the two bases 1 at the front and rear ends and the ground, so that the three bases 1 are unfolded, and the steel cage is supported by the support seat 14. When supporting steel cages of different diameters, the screw 15 drives the corresponding two support seats 14 to slide inward or outward by rotating the turntable 16, so that the distance between the two support seats 14 matches the diameter of the steel cage, and the positioning rod 17 is made to slide inward by rotating the knob 18, and the steel cage is locked on the support seat 14 for fixing.
