The following embodiments are used to illustrate the utility model.

[0028] An assembled steel structure support, such as Figure 1 , Figure 2 and Figure 3 Shown, including

[0029] A vertical pole 10, two vertical poles 10 are provided, the two vertical poles 10 are symmetrically arranged, and the two vertical poles 10 are fixedly placed on the ground; a fastening assembly, the fastening assembly is rotatably arranged inside one side of the vertical pole 10, the fastening assembly includes a rotating cylinder 21 and a clamping block 22, the rotating cylinder 21 is rotatably arranged inside the vertical pole 10, the clamping block 22 is movably arranged inside the rotating cylinder 21, and the clamping block 22 is movably arranged inside the vertical pole 10; a telescopic assembly, the telescopic assembly is movably arranged between the two vertical poles 10, the telescopic assembly includes a pull rod 11, a sleeve rod 12, a telescopic cross bar 13 and a supporting cross bar 16, the pull rod 11 is movably arranged in the supporting cross bar 16, the supporting cross bar 16 is located between the two vertical poles 10, the pull rod 11 is movably arranged on the outside of the vertical pole 10, the sleeve rod 12 is slidably arranged in the telescopic cross bar 13, the sleeve rod 12 is threadedly arranged in one of the vertical poles 10, and the telescopic cross bar 13 is threadedly arranged in the other vertical pole 10.

[0030] Specifically, the distance between the two vertical poles 10 is determined according to the length of the object to be stored, and then the pull rod 11 in the telescopic assembly is fixed by using the fastening assembly. In this way, the entire device can control the rotation of the block 22 in the pull rod 11 by using the rotation between the rotating cylinder 21 and the vertical pole 10 and the connection relationship between the clamping block 22 and the rotating cylinder 21, and clamp the pull rod 11 by using the shape of the clamping block 22 after rotation, so as to fix the pull rod 11. In this way, not only does it not need to prepare additional bolts, but also the inseparable connection relationship between the rotating cylinder 21 and the vertical pole 10 can be used to make the installation between the vertical pole 10 and the pull rod 11 more convenient and quick; by setting the telescopic assembly, pulling the telescopic cross bar 13, the telescopic cross bar 13 slides in the sleeve rod 12, thereby extending the distance between the two vertical poles. The extended distance is combined with the elastic connection between the pull rod 11 and the supporting cross bar 16, which can not only meet the storage needs of various materials, but also enhance the overall practicality of the bracket.

[0031] like Figure 1 and Figure 2 As shown, different threaded holes 14 are respectively opened on the inner sides of the two vertical rods 10, one end of the sleeve rod 12 is fixedly connected to a threaded head 18, and two threaded heads 18 are provided. Another threaded head 18 is fixedly connected to the end of the telescopic cross bar 13 away from the sleeve rod 12, and the two threaded heads 18 are respectively threadedly connected in the corresponding threaded holes 14; Figure 1 , Figure 2 and Figure 4 As shown, the sleeve rod 12 is a square ring, and a plurality of slots 24 are symmetrically provided on the inner wall surface of the sleeve rod 12. A circular groove is provided at one end of the telescopic cross bar 13 away from the threaded head 18, and a small spring 25 is fixedly provided in the circular groove. A blocking block 19 is fixedly connected to the other end of the small spring 25. The blocking block 19 is elastically connected to the circular groove through the small spring 25, and the blocking block 19 is clamped in the circular groove and the slot 24.

[0032] Specifically, the length to which the telescopic cross bar 13 and the sleeve rod 12 should be stretched is determined according to the length of the stored material, and the telescopic cross bar 13 is pulled to make the telescopic cross bar 13 slide inside the sleeve rod 12. At the same time, the blocking block 19 at one end of the telescopic cross bar 13 will be squeezed by the inner wall of the sleeve rod 12, and then the blocking block 19 will enter the circular groove of the telescopic cross bar 13 through the contraction of the small spring 25, and pop out when it reaches the slot 24. When the telescopic cross bar 13 and the sleeve rod 12 reach the appropriate length, the blocking block 19 is stuck in the slot 24 at the appropriate position. At this time, the threaded head 18 connected to the sleeve rod 12 is twisted into the threaded hole of one of the vertical rods 10, and then the threaded hole of the other vertical rod 10 is aligned with the threaded head 18 connected to the telescopic cross bar 13. Tighten it to fix the positions of the two vertical rods 10 with the help of the telescopic cross bar 13 and the sleeve rod 12.

[0033] like Figure 2 and Figure 3 As shown, the pull rod 11 is a U-shaped structure, and the supporting cross bar 16 is a square box structure. Square through holes are respectively provided on the side surfaces of both ends of the supporting cross bar 16. The pull rod 11 moves through the square through holes. A telescopic spring 20 is fixedly provided on the inner wall of the side surface of the supporting cross bar 16 with the square through holes. The other end of the telescopic spring 20 is connected to the inner wall surface of the pull rod 11. The telescopic spring 20 is located between the pull rod 11 and the supporting cross bar 16. The pull rod 11 is elastically connected to the supporting cross bar 16 through the telescopic spring 20.

[0034] Specifically, since a pull rod 11 is slidably provided at both ends of the support cross bar 16, and one end of the pull rod 11 is located inside the support cross bar 16, when in use, one end of the pull rod 11 is pulled to make the other end of the pull rod 11 squeeze the tension spring 20, thereby extending the distance between the two pull rods 11 to adapt to the length of the telescopic cross bar 13 and the sleeve rod 12 after stretching.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, a plurality of shrink holes 15 are opened on one side of the vertical rod 10. The shrink holes 15 are located on the opposite side of the threaded hole 14. The shrink holes 15 are composed of a cylindrical rotating hole and a cross clamping hole. The cylindrical rotating hole is rotatably connected to the rotating cylinder 21, and the cross clamping hole is clamped to the clamping block 22. Figure 4 and Figure 5 As shown, the interior of the drum 21 is a nail-shaped groove, and the clamping block 22 is composed of a nail-shaped cylinder and a cross block. A clamping spring 23 is fixedly arranged between the nail-shaped cylinder and the inner wall surface of the nail-shaped groove. The clamping block 22 is elastically connected to the drum 21 through the clamping spring 23, and the cross block is clamped in the cross clamping hole of the shrinkage hole 15; Figure 2 and Figure 3As shown, a locking hole 17 is provided on the outer wall surface of the pull rod 11 away from the telescopic spring 20. The locking hole 17 consists of a cylindrical groove and a cross through hole. The nail-shaped cylinder of the locking block 22 slides and rotates in the cross through hole, and the cross block of the locking block 22 rotates in the cylindrical groove, and the cylindrical groove limits the cross block.

[0036] Specifically, when in use, first align the positioning hole 17 of the pull rod 11 with the cross block of the clamping block 22, and then pull the clamping block 22 to make the clamping block 22 squeeze the clamping spring 23 and then mobilize the nail-shaped cylinder to slide out in the nail-shaped groove of the rotating drum 21. The depth of the private clamping here is less than the thickness of the clamping block 22. The protruding part of the clamping block 22 can be used as a force application point for pulling. When the clamping block 22 slides out, it will pass through the cross perforation of the positioning hole 17. At this time, the clamping block 22 is rotated. Since the clamping block 22 and the rotating drum 21 are connected by the clamping spring 23, the rotation of the clamping block 22 can drive the rotating drum 21 to rotate at the same time. When the cross block of the clamping block 22 is no longer facing the cross perforation, the clamping block 22 can be released. At this time, the cross block of the clamping block 22 is located in the cylindrical groove of the positioning hole 17. At this time, the pull rods 11 located at both ends of the supporting cross bar 16 can be clamped by the clamping blocks 22 respectively, thereby being fixed.
