[0035] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1

[0037] See also Figures 1-8 As shown, the purpose of this embodiment is to provide a modular cantilever external frame with a self-locking function, including a cantilever main beam 1, a plurality of cantilever main beams 1 are fixedly connected to the surface of a building wall, a vertical pole 11 is movably connected to the top of the cantilever main beam 1 near both ends, a plurality of self-locking components 12 are movably connected to the outer wall of the vertical pole 11, and a folding component 13 is movably connected inside the self-locking component 12;

[0038] A cross bar 14 is movably connected between the parallel self-locking components 12 on the plurality of vertical poles 11, a diagonal rod 17 is movably connected between the self-locking components 12 between the diagonals on the plurality of vertical poles 11, the plurality of self-locking components 12 are movably connected to the scaffolding board 15, and a buckle component 16 is movably connected between the scaffolding board 15 and the outer wall of the vertical pole 11;

[0039] The folding assembly 13 can drive the self-locking assembly 12 to stretch, flip, and rotate, and the crossbar 14 and the diagonal rod 17 are inserted between the multiple self-locking assemblies 12. Then the self-locking assembly 12 rotates to fix the positions of the crossbar 14 and the diagonal rod 17. The self-locking assembly 12 also facilitates workers to climb on the outer wall of the vertical pole 11, and is also used to support the scaffolding board 15;

[0040] In summary, the improvements are:

[0041] By adjusting the self-locking component 12, the folding component 13 is driven to fold, rotate, and stretch inside the self-locking component 12, so as to facilitate the adjustment of the locking direction of the self-locking component 12. After the cross bar 14 and the diagonal bar 17 are placed inside the hole of the self-locking component 12, the positions of the cross bar 14 and the diagonal bar 17 are automatically locked by the rotation of the self-locking component 12. In addition, the protective net can also be tied inside the hole of the self-locking component 12 to improve the winding strength of the protective net. Through the multiple self-locking components 12 on the vertical pole 11, it is convenient for workers to step on the self-locking components 12 and climb up along the outer wall of the vertical pole 11. At the same time, the scaffolding board 15 can also be supported between the multiple self-locking components 12, so as to improve the installation efficiency of the scaffolding board 15.

[0042] After laying a plurality of scaffolding boards 15 on top of a plurality of self-locking components 12, the scaffolding boards 15 are flipped on the outer wall of the vertical pole 11 through the buckle component 16 to limit the position between the scaffolding boards 15 and the vertical pole 11, thereby improving the stability of the scaffolding boards 15 when stepped on.

[0043] First, the specific structure of the self-locking component 12 is disclosed. The self-locking component 12 includes a support plate 120, which is movably connected to the outer wall of the vertical rod 11. The inner wall of the support plate 120 is fixedly connected with a clamping ring 122, and the clamping ring 122 is movably connected to the inner ring groove of the outer wall of the vertical rod 11. Both ends of the support plate 120 are movably connected with a clamping plate 121, and an elastic member 123 and a folding component 13 are fixedly connected between the end of the clamping plate 121 and the inside of the support plate 120. The elastic member 123 is wrapped around the outer wall of the folding component 13. The clamping plates 121 on multiple support plates 120 are respectively movably connected with a cross bar 14 and an inclined rod 17. By twisting the clamping plate 121, the elastic member 123 is driven to rotate and twist inside the support plate 120, so as to adjust the clamping plate 1 The direction of 21 is adjusted by placing the cross bar 14 between the holes of the two card plates 121. At this time, the elastic member 123 rotates by its own elastic force, thereby driving the card plate 121 to rotate in the opposite direction, and the cross bar 14 is stuck between the holes of the two card plates 121. When the inclined rod 17 is fixed, the card plate 121 is also twisted. In order to avoid the two inclined rods 17 from blocking each other when crossing, the elastic member 123 is pulled by pulling the card plate 121 to stretch one of the inclined rods 17, so that one of the inclined rods 17 is stuck between the holes of the two pulled card plates 121. The elastic member 123 rebounds, thereby clamping the inclined rod 17 and tightening the outer wall of the other inclined rod 17, thereby improving the fixing stability of the inclined rod 17.

[0044] The elastic member 123 is a constant force spring structure. The constant force spring adopts high-quality materials and advanced manufacturing technology, and can provide a long service life and excellent durability. At the same time, the constant force spring has the characteristic of self-stability, that is, after being acted upon by external force, it can automatically adjust and return to the initial constant force state, so that the product can quickly adapt to temporary load changes and maintain a stable working state.

[0045] Secondly, the specific structure of the folding assembly 13 is disclosed. The folding assembly 13 includes a slide bar 131, which is movably connected to the inside of the support plate 120. The slide bar 131 is movably connected to the support bar 130. The end of the support bar 130 passing through the support plate 120 is fixedly connected to the end of the card plate 121. The outer wall of the other end of the support bar 130 is fixedly connected to a rotating shaft 132. The rotating shaft 132 is movably connected to the inside of the slide bar 131. By pulling the card plate 121 to drive the elastic member 123 to stretch, the support bar 130 and the slide bar 131 are driven to telescope and move inside the support plate 120. By pulling the support rod 130 out from the support plate 120, the tensile stability of the elastic member 123 is improved, and by pressing the card plate 121, the support rod 130 is driven to flip downward inside the slide rod 131, and the rotating shaft 132 is driven to rotate inside the slide rod 131, so that the support rod 130 drives the card plate 121 to fold at the end of the support plate 120, which is convenient for fixing the cross bar 14 between the card plates 121 on the outer wall of the vertical pole 11 on the same cantilever main beam 1, thereby improving the stability between multiple vertical poles 11, and the support rod 130 can also support the tensile rotation position of the elastic member 123.

[0046] Finally, the specific structure of the snap assembly 16 is disclosed. The snap assembly 16 includes a slider 160 movably connected to the inside of the slide groove at both ends of the scaffolding board 15, and a fork frame 161 is movably connected to the outer wall of one side of the slider 160 near the top. A hinge 162 is fixedly connected between the fork frame 161 and the top of the slider 160, and the inner wall of the fork frame 161 is movably connected to the outer wall of the vertical pole 11. After the scaffolding board 15 is placed between the clamping plates 121 of the two vertical poles 11, the slider 160 is slid inside the scaffolding board 15 to align the fork frame 161 with the outer wall of the vertical pole 11, and the fork frame 161 is driven to flip over by the hinge 162, so that the inner wall of the fork frame 161 is clamped to the outer wall of the vertical pole 11, and the fork frame 161 is limited by the vertical pole 11, thereby improving the stability of the scaffolding board 15.

[0047] Considering that most of the connections between the vertical poles 11 and the cantilever main beam 1 are mostly welding methods, this connection method is rather cumbersome when disassembling the scaffolding subsequently. Therefore, a screw rod 110 is movably connected near the bottom inside the vertical pole 11, and the screw rod 110 is fixedly connected to the top of the cantilever main beam 1. A fixed rod 111 is movably connected inside the self-locking assembly 12 near the bottom of the vertical pole 11, and the fixed rod 111 is fixedly connected to the top of the cantilever main beam 1. A support rod 112 is fixedly connected between multiple self-locking assemblies 12. By aligning the hole of one of the clamping plates 121 near the bottom of the vertical pole 11 with the fixed rod 111, and rotating the vertical pole 11 by screwing it to rotate on the outer wall of the screw rod 110, the vertical pole 11 is connected to the screw rod 110, thereby fixing the vertical pole 11 on the top of the cantilever main beam 1. At the same time, when rotating the vertical pole 11, since the fixed rod 111 limits the position of the clamping plate 121, and the support rod 112 connects all the support plates 120 on the vertical pole 11, the snap ring 122 rotates on the outer wall of the vertical pole 11, avoiding the rotation of the vertical pole 11 from affecting the direction of the support plates 120.

[0048] In order to facilitate improving the supporting force between multiple crossbars 14, therefore, a convex rod 140 is fixedly connected to one end of the crossbar 14, and a card slot 141 is provided at the other end of the crossbar 14. The convex rod 140 of one crossbar 14 is movably connected inside the card slot 141 of another crossbar 14. After connecting the crossbars 14 between two clamping plates 121, by aligning the convex rod 140 of one crossbar 14 with the card slot 141 of another crossbar 14, the two crossbars 14 are clamped to each other, thereby enabling the two crossbars 14 to support each other and improving the supporting force of the crossbars 14.

[0049] As shown above, the working principle of this solution is as follows:

[0050] By aligning the hole of one of the clamping plates 121 near the bottom of the vertical pole 11 with the fixed rod 111, and rotating the vertical pole 11 by screwing it to rotate on the outer wall of the screw rod 110, the vertical pole 11 is connected to the screw rod 110, thereby fixing the vertical pole 11 on the top of the cantilever main beam 1. At the same time, when rotating the vertical pole 11, since the fixed rod 111 limits the position of the clamping plate 121, and the support rod 112 connects all the support plates 120 on the vertical pole 11, the snap ring 122 rotates on the outer wall of the vertical pole 11, avoiding the rotation of the vertical pole 11 from affecting the direction of the support plates 120;

[0051] By twisting the card plate 121, the elastic member 123 is driven to rotate and twist inside the support plate 120, and the direction of the card plate 121 is adjusted, while driving the support rod 130 and the slide rod 131 to telescopically move inside the support plate 120. By pulling the support rod 130 out of the support plate 120, the tensile stability of the elastic member 123 is improved. By placing the cross bar 14 between the holes of the two card plates 121, the elastic member 123 rotates by its own elastic force, thereby driving the card plate 121 to rotate in the opposite direction, and the cross bar 14 is stuck between the holes of the two card plates 121.

[0052] After the crossbar 14 is connected between the two clamping plates 121, the protruding rod 140 of one crossbar 14 is aligned with the clamping groove 141 of the other crossbar 14, so that the two crossbars 14 are clamped with each other, so that the two crossbars 14 support each other, thereby improving the supporting force of the crossbar 14;

[0053] When the inclined rod 17 is fixed, the clamping plate 121 is also twisted, and the support rod 130 is turned downward inside the sliding rod 131 by pressing the clamping plate 121, and the rotating shaft 132 is driven to rotate inside the sliding rod 131, so that the support rod 130 drives the clamping plate 121 to fold at the end of the support plate 120, which is convenient for the cross bar 14 to be fixed between the clamping plates 121 on the outer wall of the vertical rod 11 on the same cantilever main beam 1, thereby improving the stability between the multiple vertical rods 11, and the support rod 130 can also support the stretched rotation position of the elastic member 123. In order to avoid mutual obstruction between the two inclined rods 17 when crossing, the elastic member 123 is stretched by pulling the clamping plate 121, so that one of the inclined rods 17 is stuck between the holes of the two pulled clamping plates 121, and the elastic member 123 rebounds, so that the inclined rod 17 is clamped and tightened on the outer wall of the other inclined rod 17, thereby improving the fixing stability of the inclined rod 17;

[0054] By pulling the card plate 121 to drive the elastic member 123 to stretch, the protective net can also be tied inside the hole of the card plate 121 to improve the wrapping strength of the protective net, and the multiple support plates 120 on the vertical pole 11 make it convenient for workers to step on the self-locking component 12 and climb up along the outer wall of the vertical pole 11. At the same time, the multiple card plates 121 can also support the scaffolding board 15 to improve the installation efficiency of the scaffolding board 15. After the scaffolding board 15 is placed between the card plates 121 of the two vertical poles 11, the slider 160 is used to slide inside the scaffolding board 15, and the fork frame 161 is aligned with the outer wall of the vertical pole 11. The hinge 162 drives the fork frame 161 to flip, so that the inner wall of the fork frame 161 is clamped on the outer wall of the vertical pole 11, and the fork frame 161 is limited by the vertical pole 11, thereby improving the stability of the scaffolding board 15.

Those skilled in the art should understand that the present invention is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
