[0002] At present, with the reform and development of new building models, the research and development of steel structure buildings are becoming more and more important. Steel structure buildings are welcomed by many companies because of their good connection strength and earthquake resistance. At present, most of the load-bearing supports used in some construction sites are assembled steel structure supports.

[0003] The existing patent (publication number: CN219711099U) discloses an assembled steel structure bracket, including a bottom plate, a bracket plate movably connected to the top of the bottom plate, an adjustment mechanism provided on the top of the bottom plate, and a limit assembly provided on the top of the bottom plate. The adjustment mechanism includes a fixed block fixedly connected to the top of the bottom plate, a fixed frame fixedly connected to the top of the bottom plate, a screw connected to the inside of the fixed frame, a worm wheel fixedly connected to the outside of the screw, and a worm connected to the inside of the fixed frame. The assembled steel structure bracket is provided with an adjustment mechanism, and the worm drives the worm wheel to rotate by rotating the worm, and the worm wheel drives the screw to rotate, and the screw drives the movable block and the connecting rod to move, so that the bracket plate is raised, and the height of the bracket plate is conveniently adjusted. Through the limit assembly, when the bracket plate rises to a certain height, the movable rod is limited by docking the pull rod with the movable rod.

[0004] However, during the use of the above-mentioned bracket, the worm is rotated, the worm drives the worm wheel to rotate, the worm wheel drives the screw to rotate, and the screw drives the movable block and the connecting rod to move, so as to lift the bracket plate. However, one side of the bracket plate is subjected to force, and the force is not uniform, which can easily cause serious wear of the movable rod on one side, affecting its service life. At the same time, during the lifting process, workers are required to continuously pull up the pull rod, which makes the operation more cumbersome. Utility Model Content

Two moving blocks 3 are threadedly connected at both ends of the outer surface of the bidirectional threaded rod 2. Two limit rods 13 are fixedly connected between the left and right inner walls of the base plate 1, and each limit rod 13 is slidably connected to the moving block 3. Through the setting of the limit rod 13, the movement of the moving block 3 can be limited to avoid shaking during the movement. The upper surfaces of the two moving blocks 3 are hinged with two support rods 4, and the tops of the four support rods 4 are hinged with the same support plate 5.

[0033] See also Figure 1 , Figure 2 and Figure 3 In addition, two locking plates 14 are fixedly connected to the right side of the base plate 1, and a worm 15 is rotatably connected between the two locking plates 14 through a bearing. A worm wheel 16 is fixedly connected to the right end of the bidirectional threaded rod 2, and the worm wheel 16 is meshingly connected with the worm 15. The self-locking property of the worm wheel 16 and the worm 15 can improve the stability of the support plate 5 when it is lifted or lowered.

[0034] See also Figure 1 , Figure 2 and Figure 4Four limit sleeves 6 arranged in a matrix are fixedly connected to the upper surface of the base plate 1, and a limit block 7 is inserted into the interior of each limit sleeve 6 tube. A plurality of equidistantly arranged ratchet grooves 8 are provided on one side of each limit sleeve 6, and two limit plates 9 are fixedly connected to one side of each limit sleeve 6. A limit shaft 10 is rotatably connected between every two adjacent limit plates 9 through a bearing, and a pawl 11 is fixedly connected to the outer surface of each limit shaft 10, and the top of each pawl 11 is clamped with the ratchet groove 8 adjacent to it, and a torsion spring 12 is fixedly installed on the front and back of each pawl 11, and the other end of each torsion spring 12 is fixedly connected to the limit plate 9 adjacent to it. By setting the torsion spring 12, the purpose of close contact between the top of the pawl 11 and the ratchet groove 8 can be achieved.

[0035] See also Figure 1 , Figure 2 and Figure 4 At the same time, one side of each pawl 11 is fixedly connected to a release rod 17. By setting the release rod 17, the limit of the pawl 11 can be released. One side of each limit sleeve 6 is fixedly connected to an F-shaped frame 18. A release shaft 19 is rotatably connected between each limit sleeve 6 and the F-shaped frame 18 adjacent to it. The outer surface of each release shaft 19 is fixedly connected to a release plate 20. By setting the release plate 20, it can be achieved that when rotating, it contacts the release rod 17 and drives the pawl 11 to flip. The inner side wall of each F-shaped frame 18 is fixedly connected to a motor 21. The output end of each motor 21 is fixedly connected to the release shaft 19 adjacent to it. By setting the motor 21, power can be provided for the rotation of the release shaft 19.

[0036] See also Figure 1 , Figure 2 and Figure 3 In addition, two brackets 22 are fixedly connected to the left side of the base plate 1, and a controller body 23 is installed on the left side of the two brackets 22. The front end of the worm 15 is fixedly connected to the output end of the external motor. Each motor 21 and the external motor are electrically connected to the controller body 23. Through the setting of the controller body 23, the control purpose of the motor 21 and the external motor can be achieved.

[0037] An assembled steel structure bracket 22 in the present embodiment can make the bottom of the support plate 5 bear the force evenly by means of the bidirectional threaded rod 2, thereby improving its stability during lifting and lowering. At the same time, the stability during lifting and lowering can be further improved by means of the setting of the limit block 7 and the limit cylinder. The set pawl 11 and ratchet can continuously limit the limit block 7 during and after the lifting and lowering of the support plate 5, thereby preventing the support plate 5 from sliding downward and improving the overall safety.

[0038] It should be noted that the controller body 23 can be disassembled.

[0039] The working principle of the above embodiment is as follows: when in use, the worm 15 is driven to rotate by the controller, and the worm 15 drives the worm wheel 16 to rotate, and the worm wheel 16 drives the bidirectional threaded rod 2 to rotate, driving the two moving blocks 3 to approach each other under the limit of the limit rod 13, so that the support rod 4 evenly pushes the support plate 5 to move upward. During the upward movement of the support plate 5, the limit block 7 can limit it to ensure its stable upward movement. During the movement of the limit block 7, the ratchet 11 can be squeezed to flip outward. When the support plate 5 falls, the ratchet 11 can limit the limit block 7 to improve its support stability. When the support plate 5 needs to be lowered, the motor 21 is controlled to rotate to drive the release shaft 19 and the release plate 20 to rotate, and the release plate 20 flips and contacts with the release rod 17, and squeezes the ratchet 11 to flip outward, thereby releasing the limit on the limit block 7, and driving the two moving blocks 3 to move away from each other, so that the support plate 5 is reset.
