[0012] The beneficial effects of this utility model are as follows: 1. The present invention relates to an indoor decoration scaffolding. The folding mechanism utilizes a cross-hinged structure. Through the cooperation of a first hinge seat, a first folding arm, a second hinge seat, a third hinge seat, a second folding arm, and a fourth hinge seat, the upright plates can be moved closer or further apart, flexibly adjusting the scaffolding size. This facilitates storage and transportation and adapts to different indoor construction spaces. The fixing mechanism is based on a fixed base. Guide rails and guide columns ensure stable movement of the sliding handle. A return spring pushes the first limiting post into the limiting hole of the L-shaped fixing plate, quickly locking the folding mechanism in its unfolded state and preventing accidental retraction under force. Pulling the sliding handle unlocks the mechanism, making operation convenient. Both mechanisms work together to enhance flexibility and stability.

[0013] 2. The beneficial effect of the lifting caster mechanism in the indoor decoration scaffolding described in this utility model is that the first upright plate, the second upright plate and the first fixed plate are connected by the first hinge, and the third upright plate, the fourth upright plate and the second fixed plate are connected by the second hinge. The movable wheels at the bottom of the first fixed plate and the second fixed plate provide a foundation for the movement of the scaffolding. When movement is required, the fixed plate is rotated to make the movable wheels land. The second limit post rotates with the fixed plate. The damper drives the limit plate to rotate around the fixed axis and locks into the second limit post. The locking angle ensures that the movable wheels can bear the load stably. When fixing is required, the limit plate is pried open to unlock, and the fixed plate is rotated in the opposite direction to retract the wheels and let the upright plate land.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1 to 5 As shown in the embodiment of this utility model, an interior decoration scaffold includes a footboard 7. Below the footboard 7 are a first upright plate 1, a second upright plate 11, a third upright plate 12, and a fourth upright plate 13. The first and second upright plates 11 are symmetrically arranged with the third and fourth upright plates 12 and 13. Folding mechanisms 2 are respectively provided between the first and second upright plates 11 and the third and fourth upright plates 12 and 13, for retracting or unfolding through hinged folding, thereby adjusting the overall size of the scaffold. A fixing mechanism 3 is provided on the folding mechanism 2 for locking and fixing the unfolded state of the folding mechanism 2. The outer walls of the first column plate 1 and the second column plate 11 are bolted together with a lifting caster mechanism 4. The bottom end of the lifting caster mechanism 4 is provided with a movable wheel 5, and one end of the lifting caster mechanism 4 is bolted to the outer wall of the third column plate 12 and the fourth column plate 13. The top of the first column plate 1, the second column plate 11, the third column plate 12 and the fourth column plate 13 are provided with an auxiliary mechanism 6 to support the pedal 7 to form a stable working plane. The pedal 7 is detachably and movable on the upper surface of the auxiliary mechanism 6. The upper surface of the pedal 7 is provided with anti-slip raised texture to improve the foot friction of the construction personnel during operation. The side of the pedal 7 is provided with a guardrail.

[0018] Specifically, the scaffolding uses platform 7 as its working platform. The first upright plate 1, second upright plate 11, third upright plate 12, and fourth upright plate 13 below it are symmetrically distributed. The scaffolding is retracted or expanded as a whole through the hinged linkage of the folding mechanism 2, thereby adjusting the scaffolding size to adapt to different indoor spaces. After expansion, the fixing mechanism 3 locks the folding mechanism 2 to prevent accidental movement and ensure structural stability. The lifting caster mechanism 4 on the outer wall of the first upright plate 1 and second upright plate 11 connects to the third upright plate 12 and fourth upright plate 13, and the moving wheels 5 at their bottom allow for overall movement of the scaffolding. The auxiliary mechanism 6 at the top supports the platform 7 to form a stable working plane. The platform 7 is detachable, and the anti-slip raised texture on its upper surface increases the friction for workers' feet, ensuring work safety. Side guardrails further protect workers' safety, preventing accidental falls during operation. The overall design balances flexibility and safety.

[0019] like Figures 2 to 4 As shown, the folding mechanism 2 includes a first hinge seat 21 and a third hinge seat 24, which are respectively fixedly installed on the inner outer walls of the first column plate 1 and the third column plate 12. A first folding arm 23 is installed in the first hinge seat 21 through a bearing. A second hinge seat 22 is installed at one end of the first folding arm 23 through a bearing. The second hinge seat 22 is fixedly installed on the inner outer walls of the second column plate 11 and the fourth column plate 13. A second folding arm 26 is installed in the third hinge seat 24 through a bearing. A fourth hinge seat 25 is installed at one end of the second folding arm 26 through a bearing. The fourth hinge seat 25 is fixedly installed on the inner outer walls of the second column plate 11 and the fourth column plate 13. A fixing mechanism 3 is fixedly installed on the surface of the third hinge seat 24. The fixing mechanism 3 includes a fixing seat 31 fixedly installed on the surface of the third hinge seat 24. A guide rail 32 is symmetrically fixedly installed on the outer wall of the fixing seat 31. A sliding handle 35 is slidably installed inside the guide rail 32. A first limiting post 36 is fixedly installed at the front end of the sliding handle 35. A guide post 33 is fixedly installed on the inner wall of the fixing seat 31. A return spring 34 is sleeved on the surface of the guide post 33. One end of the return spring 34 is fixedly installed on the inner wall of the fixing seat 31, and the other end of the return spring 34 is fixedly installed on the rear end of the sliding handle 35. An L-shaped fixing plate 37 is fixedly installed on the surface of the second folding arm 26. A limiting hole 38 is opened in the L-shaped fixing plate 37. The first limiting post 36 is adapted to the limiting hole 38.

[0020] Specifically, the folding mechanism 2 is a cross-hinged structure. A first hinge seat 21 is fixed to the inner outer wall of the first column plate 1. The first hinge seat 21 is movably connected to one end of the first folding arm 23 through a bearing. The other end of the first folding arm 23 is connected to the second hinge seat 22 through a bearing. The second hinge seat 22 is fixed to the inner outer wall of the second column plate 11, forming a one-sided connection between the first column plate 1 and the first folding arm 23 and the second column plate 11. At the same time, a third hinge seat 24 is fixed to the inner outer wall of the third column plate 12. The third hinge seat 24 is movably connected to one end of the second folding arm 26 through a bearing. The other end of the second folding arm 26 is connected to the fourth hinge seat 25 through a bearing. The fourth hinge seat 25 is fixed to the inner outer wall of the fourth column plate 13, forming a one-sided connection between the third column plate 12 and the second folding arm 26 and the fourth column plate 13. When the scaffold dimensions need to be adjusted, pushing or pulling the first upright plate 1 and the third upright plate 12 or the second upright plate 11 and the fourth upright plate 13 will cause the first folding arm 23 to rotate around the first hinge seat 21 and the second hinge seat 22, and the second folding arm 26 to rotate around the third hinge seat 24 and the fourth hinge seat 25. This will cause the first upright plate 1, the second upright plate 11, the third upright plate 12 and the fourth upright plate 13 to move closer to each other or further away from each other, thus unfolding and forming a support frame. The fixed base 31 serves as the basic carrier, with symmetrically fixed guide rails 32 on its outer wall providing sliding guidance for the sliding handle 35. Guide posts 33 on the inner wall of the fixed base 31 further restrict the movement direction of the sliding handle 35 to prevent deviation. A return spring 34, fitted onto the surface of the guide post 33, is fixed at one end to the inner wall of the fixed base 31 and at the rear end of the sliding handle 35. In its natural state, it exerts a forward thrust on the sliding handle 35, pushing it forward along the guide rail 32, thereby causing the first limiting post 36 at its front end to extend. When the folding mechanism 2 unfolds to the preset working position, the L-shaped fixing plate 37 fixed to the surface of the second folding arm 26 rotates with the folding arm to a specific angle. Its limiting hole 38 aligns precisely with the first limiting post 36. The thrust of the return spring 34 directly pushes the first limiting post 36 into the limiting hole 38, locking the second folding arm 26 and preventing it from rotating around the third hinge seat 24, thus locking the unfolded state of the folding mechanism 2 and preventing accidental retraction of the scaffold under stress. If the folding mechanism 2 needs to be retracted, simply pull the sliding handle 35 backward. The sliding handle 35 will compress the return spring 34 and drive the first limiting post 36 to disengage from the limiting hole 38, thereby releasing the restriction on the second folding arm 26. At this time, the column plate can be pushed to retract.

[0021] like Figure 5As shown, the lifting caster mechanism 4 includes a first hinge 41 bolted to the outer walls of the first column plate 1 and the second column plate 11. One end of each first hinge 41 is bolted to a first fixing plate 43. A second limiting post 49 is fixedly installed on one side of the first fixing plate 43. The outer walls of the third column plate 12 and the fourth column plate 13 are bolted to second hinges 42. One end of each second hinge 42 is bolted to a second fixing plate 44. A third fixing block 46 and a fixing shaft 45 are fixedly installed on one side of the second fixing plate 44. A damper 47 is fixedly installed on one side of the third fixing block 46. One end of the damper 47 is fixedly connected to a limiting plate 48, and the limiting plate 48 is rotatably mounted on the surface of the fixing shaft 45. The limiting plate 48 is adapted to the second limiting post 49. The movable wheels 5 are fixedly installed at the bottom ends of the first fixing plate 43 and the second fixing plate 44.

[0022] Specifically, the first hinge 41 is fixed to the outer wall of the first column plate 1 and the second column plate 11 respectively by bolts, and its other end is connected to the first fixing plate 43 by bolts; the second hinge 42 is fixed to the outer wall of the third column plate 12 and the fourth column plate 13 respectively by bolts, and its other end is connected to the second fixing plate 44 by bolts. The bottom ends of the first fixing plate 43 and the second fixing plate 44 are both equipped with moving wheels 5 to provide a foundation for the movement of the scaffold. When the scaffold needs to be moved, the first fixing plate 43 and the second fixing plate 44 are manually rotated, and the moving wheels 5 are brought into contact with the ground by means of the rotation characteristics of the first hinge 41 and the second hinge 42. At this time, the second limiting post 49 on the side of the first fixed plate 43 rotates to the corresponding position with the fixed plate. The damper 47 on the second fixed plate 44 will drive the limiting plate 48 to rotate around the fixed axis 45, so that the limiting plate 48 is locked into the second limiting post 49, locking the angle between the first fixed plate 43 and the second fixed plate 44, ensuring that the moving wheel 5 can stably bear the load, and facilitating the adjustment of the working position of the scaffold. When the scaffold needs to be fixed for work, the external force will pry the limiting plate 48 to disengage it from the second limiting post 49. After the lock is released, the first fixed plate 43 and the second fixed plate 44 will be rotated in the opposite direction, and the moving wheel 5 will be retracted, so that the first column plate 1, the second column plate 11, the third column plate 12, and the fourth column plate 13 can directly bear the load on the ground. During the process, the damper 47 can buffer the rotation speed of the fixed plate to avoid structural impact due to excessive rotation, taking into account both the ease of operation and structural stability.

[0023] like Figure 2 As shown, the auxiliary mechanism 6 includes a first hinge handle 61 and a second hinge handle 62 hinged to the top ends of the first column plate 1 and the second column plate 11. The end of the first hinge handle 61 away from the first column plate 1 is hinged to the top end of the fourth column plate 13, and the end of the second hinge handle 62 away from the second column plate 11 is hinged to the top end of the third column plate 12. A connecting shaft 63 is mounted at the center of the first hinge handle 61 and the second hinge handle 62 via a bearing.

[0024] Specifically, the first hinge handle 61 and the second hinge handle 62 are cross-hinged through a connecting shaft 63 at the center. One end of the first hinge handle 61 is connected to the top of the first upright plate 1, and the other end is connected to the top of the fourth upright plate 13; one end of the second hinge handle 62 is connected to the top of the second upright plate 11, and the other end is connected to the top of the third upright plate 12, thus connecting the tops of the first upright plate 1, the second upright plate 11, the third upright plate 12, and the fourth upright plate 13. When the scaffolding is unfolded, the first upright plate 1, the second upright plate 11, the third upright plate 12, and the fourth upright plate 13 move away from each other, causing the two hinge handles to rotate around the connecting shaft 63. The scissor structure unfolds to form a support frame. When the scaffolding is retracted, the upright plates move closer together, and the first hinge handle 61 and the second hinge handle 62 rotate in opposite directions to retract the structure, adapting to changes in overall size and balancing support stability and folding coordination.

[0025] Working principle: The scaffolding uses platform 7 as its working platform. The first upright plate 1, second upright plate 11, third upright plate 12, and fourth upright plate 13 below it are symmetrically distributed. The scaffolding is retracted or expanded as a whole through the hinged linkage of folding mechanism 2, thereby adjusting the scaffolding size to adapt to different indoor spaces. When expanded, fixing mechanism 3 locks folding mechanism 2 to prevent accidental movement and ensure structural stability. The lifting caster mechanism 4 on the outer wall of the first upright plate 1 and second upright plate 11 connects to the third upright plate 12 and fourth upright plate 13, and the moving wheels 5 at their bottom allow for overall scaffolding movement. The auxiliary mechanism 6 at the top supports platform 7 to form a stable working plane. Platform 7 is detachable, and the anti-slip raised texture on its upper surface increases the friction for workers' feet, ensuring work safety. Side guardrails further protect workers' safety, preventing accidental falls during operation. The overall design balances flexibility and safety.
