[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments 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.

[0021] Example

[0022] See also Figure 1-Figure 8 As shown, the purpose of this embodiment is to provide a bottom reinforced anti-dumping scaffold, including a scaffold body 10, a bottom plate 11 is arranged below the scaffold body 10, and four moving wheels 12 are arranged on the lower surface of the bottom plate 11, and the four moving wheels 12 are directly facing the bottom of the four sides of the scaffold body 10, and the two sides of the scaffold body 10 are provided with a horizontal axis 13, wherein: the outer walls of the two horizontal axes 13 are provided with an anti-dumping component 20, and the bottom of the anti-dumping component 20 is slidably connected to the upper surface of the bottom plate 11 through a sliding component 14, and the anti-dumping component 20 is connected to the bottom of the bottom plate 11 through a sliding component 14. Both sides of the part 20 are meshed and connected with adjustment components 30, and the four adjustment components 30 are respectively located outside the four feet of the scaffolding body 10; the four adjustment components 30 can lift the scaffolding body 10 and wrap the moving wheels 12 to keep the moving wheels 12 away from the ground, and can also drive the anti-dumping component 20 to unfold; the four adjustment components 30 can lower the height of the scaffolding body 10 and open the moving wheels 12 to keep the moving wheels 12 close to the ground, and can also drive the anti-dumping component 20 to fold.

[0023] First, the specific structure of the adjustment component 30 is disclosed. The adjustment component 30 at least includes a mounting frame 31 and a lifting plate 34. A screw rod 32 and a limit shaft 33 are respectively arranged on both sides below the inner wall of the mounting frame 31. The upper part of the screw rod 32 extends to the upper part of the mounting frame 31 and is coaxially connected with a gear 37. A fixing frame 36 is arranged on one side of the upper surface of the mounting frame 31. The upper end of the gear 37 is rotatably connected to the lower surface of the inner wall of the fixing frame 36. The lifting plate 34 is threadedly connected to the screw rod 32, and the lifting plate 34 is slidably connected to the limit shaft 33. A lifting box 35 is arranged on the lower surface of the lifting plate 34, and the lower part of the lifting box 35 extends to the lower surface of the bottom plate 11.

[0024] The improvement is that: the motor is powered on to make it work, and the motor output shaft rotates clockwise, driving the screw rod 32 and the gear 37 to rotate clockwise. At the same time, the lifting plate 34 moves downward, and the moving wheel 12 is wrapped, so that the moving wheel 12 is away from the ground, the scaffold body 10 can be lifted, and the anti-dumping assembly 20 is also unfolded, which increases the height of the anti-dumping scaffolding and the stability of the anti-dumping scaffolding. Similarly, the motor output shaft rotates counterclockwise to drive the screw rod 32 and the gear 37 to rotate clockwise. The wheel 37 rotates counterclockwise, and at the same time, the lifting plate 34 moves upward, and the moving wheel 12 is opened, so that the moving wheel 12 is close to the ground, and the anti-dumping assembly 20 is also folded up. At this time, the anti-dumping scaffold can be moved, and when the scaffolding body 10 is at the lowest height, the stability of the position movement of the scaffolding body 10 is effectively increased, the risk of using the anti-dumping scaffold is reduced, the safety of using the anti-dumping scaffold is improved, and the flexibility of using the anti-dumping scaffold is increased, thereby improving the practicality of the anti-dumping scaffold.

[0025] Secondly, the specific structure of the anti-dumping component 20 is disclosed. The anti-dumping component 20 includes at least two support components 24, and connecting blocks 23 are provided at both ends of the two support components 24, wherein the side of one of the connecting blocks 23 away from the support component 24 is connected to the first connecting frame 22 by bolts, and the side of the first connecting frame 22 away from the connecting block 23 is provided with a connecting ring 21, and the inner wall of the connecting ring 21 is fixedly connected to the outer wall of the transverse axis 13, wherein the side of the other connecting block 23 away from the support component 24 is connected to the second connecting frame 25 by bolts; the outer walls of the two support components 24 are provided with support plates 29, and connecting rods 27 are provided at both ends of the support plates 29, and a support frame 26 is provided on the side of the upper surface of the base plate 11 close to the mounting frame 31, and the lower surface of the connecting rod 27 is slidably connected to the upper surface of the support frame 26 through a limiting component 210, and a tooth plate 28 for meshing connection with the gear 37 is provided on the side of the connecting rod 27 away from the support plate 29.

[0026] The improvement lies in that: by rotating the gear 37 clockwise, the toothed plate 28 is driven to move toward the outside of the scaffolding body 10, while the limit assembly 210 and the sliding assembly 14 are driven to be slidably connected, and the support plate 29 is driven to move away from the scaffolding body 10, so that the support assembly 24 is inclined, which is beneficial to increase the stability of both sides of the scaffolding body 10, reduce the risk of tipping, and improve the safety of the anti-tip scaffolding. Similarly, by rotating the gear 37 counterclockwise, the toothed plate 28 is driven to move closer to the scaffolding body 10, while the limit assembly 210 and the sliding assembly 14 are driven to be slidably connected, and the support plate 29 is driven to move closer to the scaffolding body 10, so that the support assembly 24 is retracted. This not only improves the flexibility of the anti-tip scaffolding, but also facilitates adjustment according to the height of the anti-tip scaffolding, and has targeted reinforcement, thereby improving the practicality of the anti-tip scaffolding.

[0027] The specific structure of the sliding assembly 14 is disclosed again. The sliding assembly 14 at least includes a slider 141. The upper surface of the slider 141 is fixedly connected to the lower surface of the second connecting frame 25. The upper surface of the base plate 11 is provided with a sliding groove 142 for sliding connection with the slider 141.

[0028] The improvement lies in that when the angle of the anti-dumping component 20 is adjusted, the slider 141 also slides inside the slide groove 142, effectively limiting the tilt angle of the support component 24, increasing the stability of the angle adjustment of the anti-dumping component 20, preventing deviation, and reinforcing the bottom of the anti-dumping scaffolding, increasing the safety of the use of the anti-dumping scaffolding, thereby improving the practicality of the anti-dumping scaffolding.

[0029] Then, the specific structure of the limit assembly 210 is disclosed. The limit assembly 210 at least includes a limit block 2101. The upper surface of the limit block 2101 is fixedly connected to one side of the lower surface of the connecting rod 27, and the upper surface of the support frame 26 is provided with a limit groove 2102 for sliding connection with the limit block 2101.

[0030] The improvement lies in that: when the gear 37 drives the tooth plate 28 to move, the limit block 2101 also slides inside the limit groove 2102, limiting the movement direction of the tooth plate 28 to prevent movement deviation, increase the stability of the position adjustment of the connecting rod 27, and thus improve the safety of the anti-dumping scaffolding.

[0031] Finally, the specific structure of the support assembly 24 is disclosed. The support assembly 24 at least includes a support column 241. Elastic members 242 are provided inside both ends of the support column 241. An extension column 243 is provided at the other end of the elastic member 242. The ends of the two extension columns 243 away from the elastic member 242 are fixedly connected to one side of the connecting block 23.

[0032] The improvement lies in that when the support plate 29 is away from the scaffolding body 10, the elastic member 242 will also be deformed and elongated. At the same time, the extension column 243 partially moves out of the interior of the support column 241, and the stability between the extension column 243 and the support column 241 is increased through the resilience of the elastic member 242. Similarly, when the support plate 29 approaches the scaffolding body 10, the elastic member 242 is also reset. At the same time, the extension column 243 enters the interior of the support column 241, which is not only simple to operate, but also convenient for storing or unfolding the anti-dumping assembly 20, thereby improving the flexibility of the anti-dumping assembly 20 and the stability of the anti-dumping assembly 20, thereby improving the practicality of the anti-dumping scaffolding.

[0033] Since dust or debris will inevitably exist on the upper surface of the base plate 11 during the use of the scaffold body 10, in order to prevent dust or debris from entering the interior of the slide groove 142 and affecting the normal use of the anti-dumping assembly 20, elastic sealing plates 15 are provided in the cavities on both sides of the opening above the slide groove 142.

[0034] The improvement lies in that: the opening above the slide groove 142 is sealed by two elastic sealing plates 15. When the slider 141 passes through, the two elastic sealing plates 15 will deform and shrink, allowing the slider 141 to slide inside the slide groove 142. It can also reduce dust or debris from entering the slide groove 142, reduce the frequency of failures, and thus increase the service life.

[0035] In order to limit the movement of the support assembly 24 and reduce damage to the support assembly 24 , rubber rings 291 are provided on the inner walls of the two openings of the support plate 29 .

[0036] The improvement lies in that: through the provision of the rubber ring 291, during the process of the support assembly 24 tilting, the rubber ring 291 also deforms accordingly, which not only limits the support assembly 24 and increases the stability of the tilting of the support assembly 24, but also reduces the scratches on the support assembly 24 caused by the support plate 29, reduces the frequency of failure of the anti-dumping scaffolding, and thus avoids economic damage.

[0037] Considering that the support column 241 rubs against the rubber ring 291 for a long time, the inner wall of the rubber ring 291 will be worn over a long period of time, which may affect the reinforcement effect of the support component 24, reduce the stability of the support component 24, and also reduce the practicality of the anti-dumping scaffolding. Therefore, the outer wall of the support column 241 is made of smooth and wear-resistant material.

[0038] The improvement lies in that: through the smooth material, the adjustment efficiency of the anti-dumping component 20 can be improved, and through the wear-resistant material, the wear on the rubber ring 291 can be reduced, the service life can be increased, the practicality of the anti-dumping scaffolding is improved, and economic losses are avoided.

[0039] In summary, the working principle of this scheme is as follows: first, the motor is powered on to make it work, and the motor output shaft rotates counterclockwise, driving the screw rod 32 and the gear 37 to rotate counterclockwise, so that the lifting plate 34 moves upward, and the moving wheel 12 is opened, so that the moving wheel 12 is close to the ground. At the same time, the gear 37 rotates counterclockwise to drive the toothed plate 28 to approach the scaffold body 10, and also drives the limit assembly 210 and the sliding assembly 14 to be slidably connected, and also drives the support plate 29 to approach the scaffold body 10, and the elastic member 242 is also reset accordingly, and the extension column 243 also enters the interior of the support column 241. At this time, the scaffold body 10 can be pushed to move the scaffold body 10 to the specified position; Afterwards, the motor is connected to a power source to make it work, and the motor output shaft rotates clockwise, driving the screw rod 32 and the gear 37 to rotate clockwise, so that the lifting plate 34 moves downward, and the moving wheel 12 is wrapped, so that the moving wheel 12 is away from the ground, and the scaffolding body 10 can be lifted. At the same time, the gear 37 rotates clockwise to drive the toothed plate 28 to move toward the outside of the scaffolding body 10, and also drives the limit assembly 210 and the sliding assembly 14 to be slidably connected, and also drives the support plate 29 away from the scaffolding body 10, so that the elastic member 242 will also be deformed and elongated, and the extension column 243 is also partially moved out of the support column 241, so that the support assembly 24 is inclined, and the use of the anti-dumping scaffolding can be completed.
