[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Reference Figure 1-4A steel structure support frame that is easy to assemble includes a support frame, the support frame includes a main frame 1 and two sub-frames 2, the two sub-frames 2 are slidably connected to the two ends of the main frame 1, and a plurality of main legs 3 are fixedly installed at the bottom end of the main frame 1. The bottom sides of the sub-frame 2 away from the main frame 1 are fixedly connected with mounting sleeves 5 on both sides, and sub-legs 4 are detachably installed in the mounting sleeves 5. A top plate 6 is detachably installed on the top of the support frame.

[0020] In this embodiment, the main frame 1 is a rectangular frame, and the two sides of the main frame 1 are respectively fixedly connected with guide rails 7, and the sub-frame 2 is a U-shaped frame, including a longitudinal connecting rod 21 and transverse support rods 22 fixedly connected to the two ends of the longitudinal connecting rod 21, the two transverse support rods 22 are parallel to each other, and the sides of the two transverse support rods 22 close to each other are respectively provided with slide grooves, and the sub-frame 2 is slidably installed on the guide rails 7 on both sides of the main frame 1 through the slide grooves on both sides. By sliding the two sub-frames 2, the effective support area of ​​the entire support frame can be adjusted to meet different support requirements.

[0021] In this embodiment, a plurality of first limiting holes 8 are provided at intervals on the outer side wall of the guide rail 7 along the length direction of the guide rail 7, and a plurality of first threaded holes 9 corresponding to the first limiting holes 8 are provided on the outer side surfaces of the two transverse support rods 22 of the sub-frame 2, and the transverse support rods 22 are fixed to the corresponding guide rails 7 by first bolts 11. When the sub-frame 2 is slid to an appropriate position, the first threaded holes 9 are aligned with the corresponding first limiting holes 8, and the first bolts 11 are screwed into the aligned first threaded holes 9 and the first limiting holes 8, so as to limit and fix the sub-frame 2 and the guide rail 7 to prevent them from sliding relative to each other during use.

[0022] In this embodiment, a plurality of reinforcing rods 10 are fixedly connected to the inner side of the main frame 1 . The plurality of reinforcing rods 10 are arranged in parallel, and both ends of each reinforcing rod 10 are fixedly connected to the inner sides of two opposite frames of the main frame 1 .

[0023] In this embodiment, the top of the auxiliary leg 4 is inserted into the installation sleeve 5, a second limiting hole is provided at the top of the side wall of the auxiliary leg 4, a second threaded hole matching the second limiting hole is provided on the side wall of the installation sleeve 5, and the auxiliary leg 4 is fixed to the installation sleeve 5 by a second bolt. When the auxiliary frame 2 is slid out to both sides of the main frame 1, in order to improve the overall stability of the support frame, the auxiliary leg 4 can be installed in the installation sleeve 5 at the bottom end of the auxiliary frame 2. After the installation is completed, the second limiting hole and the second threaded hole are exactly aligned. At this time, the second bolt is screwed into the second threaded hole and the second limiting hole, so that the auxiliary leg 4 and the installation sleeve 5 can be effectively fixed.

[0024] In this embodiment, the auxiliary support leg 4 can be installed selectively. When the auxiliary frame 2 slides outward less, the auxiliary support leg 4 does not need to be installed. When the auxiliary frame 2 slides outward more, the auxiliary support leg 4 can be installed to increase the overall stability of the support frame.
