Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of building construction, and in particular relates to a movable scaffold. Background Art
[0002] Scaffolding refers to various supports set up at construction sites for workers to operate and solve vertical and horizontal transportation. It is a common term in the construction industry and refers to the use of scaffolding on construction sites for exterior walls, interior decoration or places with high floor heights that cannot be directly constructed. It is mainly used for construction workers to work up and down or for the maintenance of external safety nets and the installation of components at high altitudes. To put it bluntly, it is a frame. Scaffolding is usually made of bamboo, wood, steel pipes or synthetic materials. Some projects also use scaffolding as a template. In addition, it is also widely used in the advertising industry, municipal administration, transportation roads and bridges, mining and other departments.
[0003] At present, most of the existing scaffolds used in construction are inconvenient to move. When in use, it is often necessary to manually adjust the grounding of the moving wheels, and then fix the moving wheels by adjusting pins or fixings. The operation is cumbersome and complicated, and the adjustment speed is slow, which affects the work efficiency of construction workers. Summary of the invention
[0004] In view of the above problems, the object of the present invention is to provide a movable scaffold with retractable wheels for easy movement.
[0005] The present invention is achieved through the following technical solutions:
[0006] A movable scaffolding comprises a first crossbar and a second crossbar which constitute the upper and lower parts of a rectangular frame, support columns which constitute the four edges of the rectangular frame, and the corners of the rectangular frame are fixed by connecting pieces, a load-bearing plate with buckle joints at both ends is arranged on the top of the rectangular frame, and a ladder is arranged on the side of the rectangular frame (the above are all prior arts); a movable scaffolding also comprises a connecting plate and a buckle mechanism; the connecting plates are in two pieces and are arranged at the bottom of the rectangular frame; wheels are arranged at the bottom of both ends of the connecting plates; the buckle mechanism is arranged on the connecting plates and connected to the wheels; the buckle mechanism comprises a connecting rod, a second clamping groove, and a telescopic rod; the connecting rod passes through the connecting plate, and the bottom end is connected to the wheel; a pressing plate is arranged on the connecting rod; a spring is arranged on the connecting rod between the pressing plate and the connecting plate; the second clamping groove is triangular and arranged on both sides of the middle section of the connecting rod; the telescopic rod is arranged in a groove arranged in the middle of the connecting plates on both sides of the connecting rod; a slow rebound material is arranged at one end of the telescopic rod facing the groove of the connecting plate.
[0007] Furthermore, in order to prevent the slow-rebound material from losing its resilience, when the wheel is retracted, the telescopic rod can enter the first slot to ensure that the slow-rebound material is in its original state. A slot one identical to the first slot is provided on the connecting rod below the second slot.
[0008] Furthermore, the slow-rebound material is memory foam.
[0009] Furthermore, in order to make the telescopic rod slide more easily in the first slot or the second slot, rotating wheels are arranged at two corners of the telescopic rod facing one end of the connecting rod.
[0010] Beneficial effects of the present invention:
[0011] The present invention can quickly extend and retract the wheels to make the scaffold movable, and one person can implement it alone. When stability is required, the wheels can be retracted to place the scaffold on the ground, which is more stable, faster and more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figure 1-Figure 3 A movable scaffolding is shown, comprising a crossbar 1 2 and a crossbar 2 5 constituting the upper and lower parts of a rectangular frame, supporting columns 1 constituting the four edges of the rectangular frame, and the corners of the rectangular frame are fixed by connecting pieces 3, a bearing plate 9 with buckle joints 10 at both ends is arranged on the top of the rectangular frame, and a ladder 8 is arranged on the side of the rectangular frame (the above are all prior arts); a movable scaffolding also includes a connecting plate 6 and a buckle mechanism 7; the connecting plates 6 are in two pieces and are arranged at the bottom of the rectangular frame; wheels 4 are arranged at the bottom of both ends of the connecting plates 6; the buckle mechanism 7 is arranged on the connecting plate 6 and is connected to the wheels 4; the buckle The mechanism 7 includes a connecting rod 73, a second card slot 75, and a telescopic rod 77; the connecting rod 73 passes through the connecting plate 6, and the bottom end is connected to the wheel 4; a pressing plate 71 is provided on the connecting rod 73; a spring 72 is provided on the connecting rod 73 between the pressing plate 71 and the connecting plate 6; the second card slot 75 is triangular and is provided on both sides of the middle section of the connecting rod 73, and is used to cooperate with the telescopic rod 77 to clamp the connecting rod 73 to prevent the spring 72 from rebounding; the telescopic rod 77 is provided in the grooves provided in the middle of the connecting plates 6 on both sides of the connecting rod 73; a slow rebound material 78 is provided at one end of the telescopic rod 77 facing the groove of the connecting plate 6.
[0021] Furthermore, in order to prevent the slow-rebound material from losing its resilience, when the wheel is retracted, the telescopic rod can enter the first slot to ensure that the slow-rebound material is in its original state. A first slot 74 identical to the first slot 75 is provided on the connecting rod 73 below the second slot 75.
[0022] Furthermore, the slow-rebound material 78 is memory foam.
[0023] Furthermore, in order to make the telescopic rod slide more easily in the first slot or the second slot, the two corners of the telescopic rod 77 facing one end of the connecting rod 73 are provided with rotating wheels 76 .
[0024] The operating steps of the present invention are:
[0025] When it is necessary to move the scaffold, the pressing plate 71 is stepped on slowly, so that the pressing plate 71 drives the spring 72 and the connecting rod 73 to move downward. At this time, the telescopic rod 77 located in the first slot 74 is pressed by the triangular inclined surface, so that the telescopic rod 77 moves into the groove of the connecting plate 6 and compresses the slow-resilient material 78. The connecting rod 73 continues to move downward until the telescopic rod 77 reaches the second slot 75. The telescopic rod 77 is slowly inserted into the second slot 75 under the elastic force of the slow-resilient material 78, and the telescopic rod 77 is stuck in the triangle of the second slot 75. At this time, the connecting rod 73 and the wheel 4 at its lower end are lowered to the ground, and the scaffold can be moved stably. When the scaffold needs to be used, the pressing plate 71 is stepped on again with the foot, so that the pressing plate 71 drives the spring 72 and the connecting rod 73 to move downward. The movable spring 72 and the connecting rod 73 continue to move downward. At this time, the triangular inclined surface on the second slot 75 compresses the telescopic rod 77, causing the telescopic rod 77 to move into the groove of the connecting plate 6 and compress the slow-rebound material 78. Then the foot is quickly lifted. At this time, the connecting rod 73 rises rapidly under the elastic force of the spring 72. Since the slow-rebound material 78 drives the telescopic rod 77 to rebound slowly, the telescopic rod 77 passes the second slot 75 and is stuck in the first slot 74. If the connecting rod 73 rises too fast and the telescopic rod 77 is not stuck in the first slot 74, the pressing plate 71 can be slowly stepped on to make the telescopic rod 77 stuck in the first slot 74, so that the wheel 4 can be lifted up and leave the ground. The four edges of the scaffolding are on the ground, and the scaffolding can be used stably.
[0026] The protection scope of the present invention is not limited to the technical solutions disclosed in the specific implementation methods. Any modifications, equivalent replacements, improvements, etc. made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
