[0029] Example

[0030] See also Figure 1-7 As shown, the technical solution provided by the utility model includes: a bracket 1, a fixing mechanism 4 is fixedly installed on the opposite sides of the bracket 1, a support rod 2 is clamped on the inner side of the fixing mechanism 4, a standing board 5 is movably installed on the upper end of the bracket 1, a baffle 7 is symmetrically rotatably connected to the upper end of the standing board 5, a positioning mechanism 8 is provided on the outer side of the baffle 7, and a baffle door 12 is symmetrically provided on the outer side of the standing board 5 in the front half of the standing board 5. The fixing mechanism 4 includes a fixing seat 401, which is symmetrically fixedly connected to the opposite side of the bracket 1. A slot 402 is provided at the upper end of the fixing seat 401, and the end of the support rod 2 is inserted into the inner side of the slot 402. An assembly cavity 407 is provided on the inner side of the fixing seat 401. The inner side of the assembly cavity 407 is slidably connected to a limiting plate 404. A clamping block 403 is fixedly installed on one side of the limiting plate 404. The clamping end of the clamping block 403 movably penetrates the cavity wall of the assembly cavity 407 and is clamped with the end of the support rod 2. A spring 405 is provided on the opposite side of the limiting plate 404 and the assembly cavity 407. A pull rod 406 is fixedly installed on the side of the limiting plate 404 close to the spring 405. The end of the pull rod 406 away from the limiting plate 404 slides through the assembly cavity 40 7. When assembling the scaffolding, you only need to stand up the two brackets 1, and then insert the end of the support rod 2 into the slot 402 of the corresponding external fixing seat 401 of the bracket 1. During the insertion process, the support rod 2 squeezes the inclined surface of the block 403 extending from the slot 402, and at the same time, the limit plate 404 connected to the block 403 slides inside the assembly cavity 407 and compresses the spring 405. When the end of the support rod 2 is inserted and the external position of the support rod 2 moves to the block 403, the spring 405 resets and pushes the block 403 connected to the limit plate 404 to clamp and fix it. In the same way, the support rods 2 on the front and rear sides of the bracket 1 can be installed to form a scaffolding, which is convenient for the staff to quickly assemble and use it on site.

[0031] Furthermore, a locking wheel 3 is symmetrically fixedly installed at the lower end of the bracket 1, and a connecting groove 13 is opened at the lower end of the standing plate 5. The standing plate 5 is plugged into the upper end of the bracket 1 through the connecting groove 13. The outer side of the standing plate 5 is threadedly connected with a first hand-tightened bolt 6, and the bolt end of the first hand-tightened bolt 6 is plugged into the outer wall of the upper end of the bracket 1. By installing the locking wheel 3 at the lower end of the bracket 1, the scaffolding can be conveniently moved and fixed for use; when installing the standing plate 5, after inserting the standing plate 5 into the bracket 1, the first hand-tightened bolt 6 is rotated and inserted into the bracket 1 through telescopic insertion.

[0032] Furthermore, a first slide groove 14 is symmetrically opened on the inner side of the assembly cavity 407, and the limiting plate 404 is slidably connected to the inner side of the assembly cavity 407 through the first slide groove 14. By symmetrically opening the first slide groove 14 on the inner side of the assembly cavity 407, the sliding of the limiting plate 404 can be facilitated.

[0033] Furthermore, the upper end surface of the snap-in end of the block 403 is inclined, and one end of the pull rod 406 close to the limit plate 404 movably passes through the middle of the spring 405. By designing the upper end surface of the snap-in end of the block 403 to be inclined, the support rod 2 can be quickly installed, and one end of the pull rod 406 passes through the middle of the spring 405, which can improve the stability of the spring 405.

[0034] Furthermore, a card slot 15 is provided on the outer side of the support rod 2, and the card-in end of the card block 403 is carded with the card slot 15. By providing the card slot 15 on the outer side of the support rod 2, the card block 403 can be conveniently carded with it.

[0035] Furthermore, the positioning mechanism 8 includes an inclined support rod 801, a shift block 803 and a shift groove 804. The shift groove 804 is symmetrically arranged on the left and right sides of the station board 5. The shift block 803 is slidably connected to the inner side of the shift groove 804. The inclined support rod 801 is rotatably connected between the baffle plate 7 and the shift block 803. The inner side of the shift block 803 is threadedly connected with a second hand-tightened bolt 802. The inner side of the shift groove 804 is symmetrically provided with a socket 805. The threaded end of the second hand-tightened bolt 802 is plugged into the socket 805. When installing the protective structure on the station board 5, only After the two baffle plates 7 on the standing board 5 are turned over, the baffle plates 7 are rotated and dragged to slide the shift block 803 inside the shift groove 804 by connecting the diagonal support rod 801. When the shift block 803 slides to one side of the shift groove 804, the second hand-tightened bolt 802 is used to extend and retract the shift block 803 so that it can be inserted into the socket 805 at the corresponding position, thereby facilitating the limited fixing of the baffle plates 7. The fixed baffle plates 7 are perpendicular to the standing board 5. After installation, the baffle door 12 can be directly inserted into the baffle plate 7 on the front side of the standing board 5 for use, which is easy to install.

[0036] Furthermore, a second slide groove 9 is symmetrically opened on the inner side of the shift groove 804, and the shift block 803 and the second slide groove 9 are slidably connected. By opening the second slide groove 9 on the inner side of the shift groove 804, the shift block 803 can slide in a limited position on the inner side of the shift groove 804.

[0037] Furthermore, one side of the blocking door 12 is rotatably connected to the baffle 7 at the front half of the standing board 5, and a recessed frame 10 is fixedly installed on the outer side of the baffle 7 at the rear half of the upper end of the standing board 5, and a flap 11 is rotatably connected to the outer side of the blocking door 12, and one end of the flap 11 is movably connected to the recessed frame 10. By rotating the blocking door 12 on the baffle 7 at the front half of the standing board 5, and flipping the blocking door 12, the flap 11 on the blocking door 12 is rotated to be inserted into the recessed frame 10 at the baffle 7 at the rear half of the standing board 5, the blocking door 12 can be conveniently fixed, thereby providing effective protection during the construction process.

[0038] The working principle of the utility model is as follows:

[0039] When the steel scaffolding for construction engineering of this embodiment is in use, when assembling the scaffolding, it is only necessary to stand up the two brackets 1, and then insert the end of the support rod 2 into the slot 402 of the corresponding external fixing seat 401 of the bracket 1. During the insertion process, the support rod 2 squeezes the inclined surface of the block 403 extending out of the slot 402, and at the same time, the limit plate 404 connected to the block 403 slides inside the assembly cavity 407 and compresses the spring 405. When the end of the support rod 2 is inserted and the external position of the support rod 2 moves to the block 403, the spring 405 resets and pushes the block 403 connected to the limit plate 404 to clamp it and fix it. The support rods 2 on the front and rear sides of the bracket 1 are installed to form a scaffolding, and then the standing board 5 is inserted into the bracket 1 and then the first hand-tightening bolts 6 are used to extend and extend the board into the bracket 1 for fixing. Finally, when installing the protective structure on the standing board 5, it is only necessary to flip the two baffles 7 on the standing board 5, and at the same time, the baffles 7 are rotated by connecting the diagonal support rods 801 to drag the moving block 803 to slide inside the moving groove 804. When the moving block 803 slides to one side of the moving groove 804, the second hand-tightening bolts 802 are used to extend and retract the moving block 803 to insert it into the socket 805 at the corresponding position. After the baffles 7 are fixed, the baffle door 12 can be inserted for use.
