DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides Figure 1-8The multifunctional scaffold shown comprises a working platform 300, a telescopic ladder 100 with adjustable length and a mobile base 200. The working platform 300 is used to provide a load-bearing interval. Two hook parts 301 are symmetrically arranged on both sides of the working platform 300. The working platform 300 is movably connected with the pedals on the telescopic ladder body of the telescopic ladder 100 through the hook parts 301. This not only ensures that the working platform 300 is firmly installed on the telescopic ladder 100, but also facilitates the disassembly and assembly of the working platform 300 on the telescopic ladder 100, making it more flexible and convenient to use. The telescopic ladder 100 is arranged on the side of the working platform 300. The telescopic ladder 100 is used for supporting and adjusting the height of the working platform 300. The height of the telescopic ladder 100 is adjustable, and the length change of the telescopic ladder 100 itself can be used to adjust the load-bearing height of the working platform 300, so as to meet the use requirements of various heights. Moreover, the adjustment process is more convenient and quicker than the existing scaffolding that adjusts the height by disassembly and assembly. After the scaffold is disassembled, the telescopic ladder 100 can be used alone, which has higher functionality. The mobile base 200 is arranged under the working platform 300. The mobile base 200 is used to support the bottom of the telescopic ladder 100. Universal wheels 201 are installed at the bottom corners of the mobile base 200, and the top corners of the mobile base 200 are fixedly connected with positioning supports 202. On the mobile base 200, the bottom of the telescopic ladder 100 is positioned by bolts and nuts through the deep grooves inside the positioning supports 202, making it more convenient and quick to disassemble and assemble the telescopic ladder 100 on the mobile base 200. At the same time, a latch can be added and installed between the positioning support 202 and the bottom of the telescopic ladder 100 to increase the installation firmness. In addition, the universal wheels 201 are equipped with wheel brakes, which not only meet the support of the mobile base 200 to the telescopic ladder 100 and the working platform 300, but also enable the entire scaffold to be moved and transported, which not only saves time and effort, but also can be transported without disassembly, and better meets the needs of flexible and convenient use.

[0028] In a preferred embodiment, the telescopic ladder 100 includes a stationary ladder 101 and a moving ladder 102 that can move along the extension direction of the telescopic ladder 100. The inner side of the hook portion 301 is movably connected to the pedal on the moving ladder 102, and the inner side of the positioning support 202 is movably connected to the bottom of the stationary ladder 101. A fixed pulley 103 is fixedly connected to the pedal at the top position of the stationary ladder 101, and a traction rope 104 is wound around the top of the outer wall of the fixed pulley 103. One end of the traction rope 104 is fixedly connected to the pedal at the bottom position of the moving ladder 102, and the other end of the traction rope 104 is fixedly connected to the pedal at the corresponding position on the stationary ladder 101. Figure 2As shown, the top of the static ladder 101 is provided with a guide kit to ensure that the moving ladder 102 can move along the outer wall of the static ladder 101, so as to achieve the purpose of the telescopic ladder 100 being retractable. At the same time, by manually pulling the traction rope 104 downwards and cooperating with the reversing transmission action of the fixed pulley 103, the other end of the traction rope 104 can pull the moving ladder 102 upward along the outer wall of the static ladder 101. When the lifting work platform 300 of the moving ladder 102 rises to the specified height position, one end of the traction rope 104 can be tied and fixed to the pedal at the bottom of the static ladder 101, and the staff can climb up to the work platform 300 or climb down from the work platform 300 through the pedal on the telescopic ladder 100, which further improves the convenience and functionality of the scaffolding.

[0029] Furthermore, both sides of the static ladder 101 are rotatably connected with auxiliary support rods with adjustable lengths, and a rotatable hinged frame 108 is provided between the auxiliary support rod and the static ladder 101. By rotating and opening the auxiliary support rod and cooperating with the limiting effect of the hinged frame 108, the auxiliary support rod can play an auxiliary fixing role for the telescopic ladder 100, thereby enhancing the stability of the telescopic ladder 100 supporting the working platform 300; the auxiliary support rod includes a connecting rod 106 and a support rod 105 movably sleeved on the outer wall of the connecting rod 106, the top of the connecting rod 106 is rotatably connected to the side wall of the static ladder 101, the end of the hinged frame 108 is hinged to the top of the outer wall of the support rod 105, and the top of the support rod 105 is movably inserted A latch 107 is connected, and a reset spring 109 is fixedly connected between the latch 107 and the support rod 105. A plurality of limit holes matching the latch 107 are spaced from top to bottom on the outer wall of the support rod 105. The latch 107 can be driven by the elastic reaction force of the reset spring 109 to automatically move back and reset, so that the latch 107 can be automatically inserted into the limit hole at the corresponding position on the connecting rod 106 after the external force is removed. In this way, the position between the support rod 105 and the connecting rod 106 can be locked. The operation is simple and convenient, and the auxiliary support rod can also satisfy the function of auxiliary support for the telescopic ladder 100, so as to achieve the purpose of enhancing the overall firmness of the scaffolding.

[0030] Next, a pull rod 400 is fixedly connected to both sides between the two telescopic ladders 100, and a positioning block 401 fixed to the side wall of the telescopic ladder 100 is movably inserted at the end of the pull rod 400, and the positioning block 401 is movably connected to a limit frame 402 at the end away from the telescopic ladder 100. The pull rod 400 configured between the two telescopic ladders 100 and located below the working platform 300 can reinforce the static ladder 101 of the two telescopic ladders 100, thereby enhancing stability, wherein the positioning block 401 and the limit frame 402 are arranged on the outer side of the static ladder 101 and the top of the inner side of the moving ladder 102, so that the pull rod 400 can be installed above the working platform 300 to act as a fence, and the limit frame 402 at the end of the positioning block 401 can be rotated so that the limit frame 402 and the positioning block 401 are arranged in the same straight line, so that the end of the pull rod 400 can be removed from the positioning block 401, which makes the use of the pull rod 400 more convenient.
