[0042] As Figures 1 - 5 shown, the present utility model provides a scaffolding support for supporting a scaffolding. The scaffolding support includes a fixed seat 1, a bearing assembly 2, and an anti-falling assembly 3. Among them, the fixed seat 1 is connected to the building wall surface 100, and a guiding groove penetrating in the vertical direction is provided on the fixed seat 1. The guide rail 200 of the scaffolding can penetrate into the guiding groove; the bearing assembly 2 is placed on the fixed seat 1, and a clamping groove is provided on the bearing assembly 2. Any limiting member 201 on the guide rail 200 can be clamped into the clamping groove; the anti-falling assembly 3 includes an anti-falling block 31 and a limiting block 32. The anti-falling block 31 is rotatably arranged in the guiding groove, and the limiting block 32 is fixedly arranged in the guiding groove. When the scaffolding is in the working state, one end of the anti-falling block 31 abuts against the limiting block 32, and the other end supports the limiting member 201. When the scaffolding rises, the limiting member 201 can drive the anti-falling block 31 to flip and avoid.

[0043] The load-bearing component 2 and the anti-falling component 3 are separately arranged. When it is necessary to fix the scaffolding to the scaffolding support, the limiting member 201 on the guide rail 200 is snapped into the card slot of the load-bearing component 2, and the fixing of the scaffolding can be completed. When it is necessary to move the scaffolding, just separate the limiting member 201 from the card slot. When the scaffolding suddenly falls, one end of the anti-falling block 31 supports on the bottom end of the limiting member 201, and the other end supports on the bottom end of the limiting block 32, thereby preventing the scaffolding from falling. When the scaffolding needs to move upward along the guiding groove, the anti-falling block 31 can be flipped and avoided under the drive of the limiting member 201.

[0044] Specifically, the fixing seat 1 includes a positioning plate 11, a cross brace 12, and two fixing members 13. Among them, the positioning plate 11 is fixedly connected to the wall surface 100, the cross brace 12 is connected to the positioning plate 11, the two fixing members 13 are arranged on the cross brace 12 at intervals in the horizontal direction, and the guiding groove is arranged between the two fixing members 13.

[0045] More specifically, the fixing seat 1 further includes a diagonal brace 14, and the diagonal brace 14 is connected between the positioning plate 11 and the cross brace 12. Along the direction away from the positioning plate 11, the diagonal brace 14 gradually extends upward.

[0046] In this embodiment, the fixing seat 1 is connected to the wall surface 100 by bolts. The bolts penetrate through the building wall and are fixed by nuts on the back of the wall. Both the cross brace 12 and the diagonal brace 14 are I-beams or T-beams, and the fixing member 13 is composed of two angle steel structures combined by bolts or welding. While being convenient for assembly, the width of the guiding groove can be adjusted by changing the connection position of the fixing member 13 to adapt to different models of the guide rail 200. In other embodiments, it can also be made by an integral forming process, which is not limited here.

[0047] Specifically, the load-bearing component 2 includes a swing arm 21 and a clamping member 22. Among them, one end of the swing arm 21 is rotatably arranged in the guiding groove, and the other end extends out of the guiding groove. The clamping member 22 is screwed to the end of the swing arm 21 extending out of the guiding groove, and the card slot is arranged on the clamping member 22. With the above arrangement, when it is necessary to fix the scaffolding, the swing arm 21 can be rotated first to point the clamping member 22 at the limiting member 201, and then the clamping member 22 is rotated to adjust the distance between the card slot and the limiting member 201, so that the limiting member 201 is snapped into the card slot to realize the fixing of the scaffolding.

[0048] More specifically, the load-bearing component 2 further includes a support member 23, and the support member 23 is rotatably arranged in the guiding groove. One end of the swing arm 21 is screwed to the support member 23. With the above arrangement of the support member 23, turning the swing arm 21 can make the clamping member 22 approach or move away from the support member 23 along the length direction of the swing arm 21, so that the variable support angle of the swing arm 21 is larger and the practicability is stronger.

[0049] In this embodiment, the bearing assembly 2 further includes a first bearing rod 24, which is connected between two groove walls of the guide groove, and the support member 23 is sleeved on the first bearing rod 24 to achieve a rotational connection. In other embodiments, the first bearing rod 24 may not be provided, and the support member 23 may be hinged to the inner wall of the guide groove to achieve a rotational connection.

[0050] More specifically, the clamping member 22 is provided with two clamping arms, each of which is provided with a clamping slot. With the above-mentioned arrangement of the clamping arms, the two clamping arms jointly support the limiting member 201, and the force is more stable.

[0051] Specifically, the anti-falling block 31 is provided with a pressing surface 311 on the side facing the limit block 32, and the pressing surface 311 can press the limit block 32 and support the limit member 201. The anti-falling block 31 is provided with an avoidance surface 312 on the side facing away from the limit block 32, and along the opening direction of the guide groove, the avoidance surface 312 gradually approaches the pressing surface 311. With the above arrangement, the avoidance surface 312 gradually approaches the pressing surface 311, so that the locking member 201 is smoother in the process of driving the anti-falling block 31 to flip, and the friction between the two is smaller, and no interference or jamming occurs.

[0052] More specifically, the anti-falling assembly 3 further includes a second bearing rod 33, the second bearing rod 33 is arranged in the guide groove, the anti-falling block 31 is rotatably connected to the second bearing rod 33, the anti-falling block 31 is sleeved on the second bearing rod 33, and can rotate relative to the second bearing rod 33, when one end of the pressing surface 311 is raised relative to the second bearing rod 33, the other end is lowered relative to the second bearing rod 33. The arrangement of the second bearing rod 33 enables the anti-falling block 31 to flip around the second bearing rod 33.

[0053] In this embodiment, there is only one pressing surface 311 and it is a planar structure. In other embodiments, there may be two pressing surfaces 311 , one of which can press against the limiting member 201 and the other can support the limiting block 32 .

[0054] In this embodiment, the avoidance surface 312 is a planar structure. In other embodiments, the avoidance surface 312 may also be a curved structure.

[0055] Specifically, the anti-falling assembly 3 further includes an elastic member 34, one end of the elastic member 34 is connected to the anti-falling block 31, and the other end is connected to the fixing seat 1, and the elastic member 34 is configured to drive the pressing surface 311 to abut against the limit block 32. The arrangement of the elastic member 34 enables the anti-falling block 31 to automatically reset after turning over to avoid the limit member 201.

[0056] In this embodiment, the anti-falling assembly 3 further includes a third bearing rod 35. The third bearing rod 35 is connected between the two groove walls of the guide groove. One end of the elastic member 34 is hooked on the third bearing rod 35, and the other end is connected to the anti-falling block 31. In other embodiments, the third bearing rod 35 may not be provided, and the elastic member 34 is connected between the inner wall of the guide groove and the anti-falling block 31.

[0057] In this embodiment, the elastic member 34 is a mechanical spring structure.

[0058] Specifically, the scaffolding support further includes a guide wheel 4. The guide wheel 4 is rotatably arranged in the guide groove. The guide rail 200 is provided with a guide groove. The guide wheel 4 extends into the guide groove, and the axial direction of the guide wheel 4 is parallel to the depth direction of the guide groove. With the above arrangement of the guide wheel 4, the guide wheel 4 can convert sliding friction into rolling friction, making the movement of the scaffolding relative to the scaffolding support smoother and more fluent.

[0059] More specifically, the guide rail 200 is provided with a sliding groove. The guide wheel 4 extends into the sliding groove, and the inner wall of the sliding groove can abut against the guide wheel 4. With the above arrangement of the sliding groove, the contact area between the guide rail 200 and the guide wheel 4 can be increased.

[0060] More specifically, along the horizontal direction, two sliding grooves are oppositely arranged, and each sliding groove is provided with a guide wheel 4, so that the guide rail 200 is evenly stressed.

[0061] In this embodiment, two guide wheels 4 are arranged at intervals along the vertical direction on a fixing member 13, which can play a certain role in preventing overturning. In other embodiments, the number of guide wheels 4 can also be set according to actual needs, which is not limited here.

[0062] In this embodiment, a rubber sleeve is arranged on the outer periphery of the guide wheel 4, so as to increase the friction between the guide wheel 4 and the guide rail.

[0063] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description.
