DETAILED DESCRIPTION

[0027] The technical solution in this embodiment will be clearly and completely described below in conjunction with the drawings in this embodiment. Obviously, the described embodiment is only a part of the embodiments of this embodiment, rather than all the embodiments.

[0028] Reference Figure 1-6 A steel structure support for construction, comprising a connecting frame 1, wherein the upper and lower ends of the connecting frame 1 are fixedly sleeved with support rods 3, the four sides of the connecting frame 1 are integrally formed with limiting sleeves 2, a moving rod 6 is slidably sleeved in the limiting sleeve 2, the moving rod 6 is fixedly connected to the limiting sleeve 2 by bolts, one end of the two moving rods 6 is provided with a rotating device, a connecting rod 7 is connected between the two rotating devices, one side of the connecting rod 7 is fixedly connected with the connecting device, one side of the connecting device is connected with a symmetrically arranged reinforcing rod 4, and the other end of the reinforcing rod 4 is fixedly connected with a fixing block fixedly connected to the support rod 3 5. During installation, use bolts to connect the connecting frame 1 and the support rod 3, then connect the moving rod 6 and the connecting rod 7, and finally install the moving rod 6 into the limiting sleeve 2 and fix it with bolts to form a basic frame. At this time, connect the reinforcing rod 4 and the connecting rod 7, and finally install the fixing block 5 on the support rod 3 with bolts to form protection. When the installation is completed, when in use, the connecting device and the rotating device absorb a certain torque or internal force to reduce some stress on the moving rod 6, the connecting rod 7 and the support rod 3, thereby ensuring the safety of the device.

[0029] The rotating device includes a limiting block 10 fixedly connected to the moving rod 6, one side of the limiting block 10 is fixedly connected to a first spring 14, and the other end of the first spring 14 is fixedly connected to a clamping block 11, a receiving block 12 is connected between the two clamping blocks 11, and one side of the receiving block 12 is integrally formed with an extension block 15 fixedly connected to the moving rod 6, the extension block 15 is fixedly connected to the connecting rod 7, and the outer wall of the extension block 15 is provided with a buffer device 9 fixedly connected to the connecting rod 7. When installing, the extension block 15 is inserted into the moving rod 6, so that the receiving block 12 enters between the two clamping blocks 11 for limitation, and at the same time, part of the buffer device 9 enters into the moving rod 6, and the two are mutually squeezed. After the moving rod 6 is connected to the limiting sleeve 2, the connecting rod 7 is limited. When the device generates a certain torque, the first spring 14 resists and causes the connecting rod 7 to rotate slightly to buffer the stress. At the same time, when the two connecting frames 1 are close to each other, they can be moved and buffered to a certain extent through the buffer device 9, so as to further avoid the generation of extrusion stress.

[0030] The buffer device 9 includes a limiting circle 91 fixedly connected to the connecting rod 7, and a buffer rod 92 is slidably sleeved on the inner wall of the limiting circle 91. A second spring 93 located in the limiting circle 91 is fixedly connected to one side of the buffer rod 92, and the other end of the second spring 93 is fixedly connected to the limiting circle 91. A limiting cavity 94 is provided in the limiting circle 91, and the second spring 93 and the buffer rod 92 are located in the limiting cavity 94. The buffer rod 92 is slidably connected to the cavity wall of the limiting cavity 94, wherein a buffer is provided in the limiting circle 91. When buffering is performed, external force acts on the buffer rod 92, squeezing the buffer and the second spring 93 to absorb stress, thereby reducing the stress on the connecting rod 7 and the moving rod 6, causing the connecting rod 7 to break.

[0031] A splicing groove 13 is provided in the moving rod 6, and the extension block 15, the clamping block 11, the receiving block 12 and the first spring 14 are all located in the splicing groove 13. A buffer groove 16 is provided at one end of the moving rod 6, and the buffer device 9 is located in the buffer groove 16. The splicing groove 13 and the buffer groove 16 both facilitate the operation of different devices and ensure a certain limiting effect.

[0032] The connecting device includes a mounting sleeve 23 fixedly connected to the connecting rod 7, a third spring 22 is fixedly connected in the mounting sleeve 23, and the other end of the third spring 22 is fixedly connected to a mounting block 21 slidably sleeved with the mounting sleeve 23, a spacing block 19 is integrally formed on one side of the mounting block 21, one end of the reinforcing rod 4 is located in the spacing block 19, the reinforcing rod 4 is connected to a threaded sleeve 18 fixedly connected to the spacing block 19, a spacing groove 20 is provided in the spacing block 19, the reinforcing rod 4 is located in the spacing groove 20, and the groove wall of the spacing groove 20 is slidably connected to the rod wall of the reinforcing rod 4, an adaptation groove 17 is provided in the reinforcing rod 4, and the middle of the threaded sleeve 18 is located in the adaptation groove 1 7, the diameter of the adaptation groove 17 is larger than the diameter of the threaded sleeve 18. During installation, first use the upper mounting block 21 to squeeze the upper third spring 22 to facilitate the lower mounting block 21 to enter the mounting sleeve 23 for connection. After the mounting blocks 21 on both sides enter the mounting sleeve 23, fix the fixing block 5 to complete the installation of the reinforcing rod 4, and then use the threaded sleeve 18 to install the reinforcing rod 4 into the spacing block 19 to achieve the connection between different reinforcing rods 4 and the connecting rod 7. At the same time, the adaptation groove 17 can adapt to the inclination of the support rods 3 on both sides, has a certain adaptability, and is limited within a certain range to ensure that the device is relatively fixed.

[0033] The cross-sections of the mounting sleeve 23 and the mounting block 21 are both rectangular structures. The cross-section area of ​​the mounting sleeve 23 is larger than that of the mounting block 21. The mounting sleeve 23 can adapt to the position of the mounting block 21 at a specified distance in a certain direction, adapt to slight deformation, and reduce the excessive stress generated by the rigid connection.

[0034] A reinforcing rib 8 is fixedly connected between the two reinforcing rods 4, and a plurality of reinforcing blocks are fixedly connected to the reinforcing rods 4. The reinforcing rib 8 performs a certain reinforcement function, and the reinforcing blocks ensure the strength of the corners.

[0035] Working principle: During installation, the connecting frame 1 is connected to the supporting rod 3 by bolts, and then the extension block 15 is inserted into the moving rod 6, so that the receiving block 12 enters between the two clamping blocks 11 for limitation, and at the same time, the buffer rod 92 enters into the moving rod 6, and cooperates with the limiting ring 91 so that the two are squeezed against each other. After the moving rod 6 is connected to the limiting sleeve 2, the connecting rod 7 is limited. At the same time, a plurality of threaded holes are provided on the limiting sleeve 2, so that the bolts can be installed in different positions to ensure the fixation of the moving rod 6 and adapt to certain errors. When the device generates a certain torque, the first spring 14 resists and causes the connecting rod 7 to rotate slightly to buffer the stress. At the same time, when the two connecting frames 1 are close to each other, the second spring 93 can make a certain Movement and buffering can further avoid the generation of extrusion stress. At this time, the entire device forms a basic framework. The upper mounting block 21 is used to squeeze the upper third spring 22 to facilitate the lower mounting block 21 to enter the mounting sleeve 23 for connection. After the mounting blocks 21 on both sides enter the mounting sleeve 23, the fixing block 5 is fixed to complete the installation of the reinforcing rod 4. Then, the reinforcing rod 4 is installed in the spacing block 19 using the threaded sleeve 18 to achieve the connection between different reinforcing rods 4 and the connecting rod 7. At the same time, the adaptation groove 17 can adapt to the inclination of the support rods 3 on both sides, and has a certain adaptability. At the same time, it is limited within a certain range to ensure that the device is relatively fixed and the installation is completed. Multiple devices can reduce some stress on the moving rod 6, the connecting rod 7 and the support rod 3 to ensure the safe use of the device.
