The bottoms of the plurality of floor plates are all installed with a stair mechanism. The stair mechanism includes a U-shaped frame. The U-shaped frame is slidably installed in the installation groove opened on the floor plate. A lead screw is rotatably installed in the middle of the installation groove. One end of the lead screw is fixedly installed with a handle, and a threaded through hole threadedly connected with the lead screw is opened on the cross beam of the U-shaped frame. A ladder member is rotatably installed at one end of the U-shaped frame away from the handle. A plurality of limiting grooves inserted and matched with the ladder member are uniformly opened at the upper ends of the two vertical plates of the U-shaped frame.

DETAILED DESCRIPTION OF THE INVENTION

[0021] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0022] The following describes in detail the specific implementation of the present utility model in conjunction with specific embodiments.

[0023] Please refer to Figures 1 to 5 , a convenient tool - type staircase scaffold provided by an embodiment of the present utility model, the convenient tool - type staircase scaffold includes:

[0024] Floor boards 1, several are provided, and X - type telescopic frames 2 are symmetrically installed between two adjacent floor boards 1, and hydraulic rods 3 for driving the X - type telescopic frames 2 to extend. The bottoms of several floor boards 1 are all installed with staircase mechanisms 4. The staircase mechanism 4 includes a U - shaped frame 42. The U - shaped frame 42 is slidably installed in the installation groove 102 opened in the floor board 1. A lead screw 43 is rotatably installed in the middle of the installation groove 102. One end of the lead screw 43 is fixedly installed with a handle 44. A threaded through - hole threadedly connected to the lead screw 43 is opened on the cross - beam of the U - shaped frame 42. A ladder member 45 is rotatably installed at the end of the U - shaped frame 42 away from the handle 44. A plurality of limiting grooves 401 inserted and matched with the ladder member 45 are evenly opened at the upper ends of the two vertical plates of the U - shaped frame 42;

[0025] The ladder member 45 includes a rectangular frame 451. One end of the rectangular frame 451 is rotatably connected to the U - shaped frame 42. A plurality of ladder boards 452 are evenly installed in the rectangular frame 451. Threaded sleeves 453 are symmetrically installed at the other end of the rectangular frame 451. The two threaded sleeves 453 are rotatably connected to the rectangular frame 451. Lead screws 454 are threadedly connected in both threaded sleeves 453. One ends of the two lead screws 454 away from the threaded sleeves 453 are commonly connected with a limiting rod 455. The limiting rod 455 is inserted and matched with the limiting groove 401.

[0026] It should be noted that when it is needed to be used, move the scaffolding to the construction site, and then control the hydraulic rods 3 between the respective laminates 1 to start, driving the corresponding X-shaped telescopic frames 2 to expand, so as to adjust the distance between two adjacent laminates 1, thereby adjusting the scaffolding to an appropriate height. After adjustment, rotate the handle 44 of the stair mechanism 4 on each laminate 1 to drive the lead screw 43 to rotate, thereby driving the U-shaped frame 42 to slide outwards along the installation groove 102, so as to slide out from one side of the laminate 1. After sliding out, flip the rectangular frame 451, and then turn the threaded sleeve 453 to drive the two screw rods 454 to drive the limiting rods 455 to extend in. After being inserted and matched with the limiting grooves 401 opened on the vertical plates of the corresponding lower U-shaped frames 42, the construction of the stair mechanism 4 is completed, so as to facilitate climbing through the tread board 452 when going up and down the scaffolding. The whole scaffolding is convenient to stretch and fold, and the climbing is safe and easy.

[0027] In an embodiment of the present invention, please refer to Figure 1 and Figure 2 , for the X-shaped telescopic frame 2, two corner ends on one side are hinged between two adjacent laminates 1, and two corner ends on the other side are respectively in sliding fit with the sliding grooves 101 opened on the corresponding laminates 1;

[0028] One end of the hydraulic rod 3 is hinged to the laminate 1, and the other end of the hydraulic rod 3 is fixedly connected to the middle hinge rod of the X-shaped telescopic frame 2.

[0029] It should be noted that: when the hydraulic rod 3 drives the X-shaped telescopic frame 2 to expand, it drives the middle hinge rod of the X-shaped telescopic frame 2 to move obliquely upwards. Two corner ends on one side of the X-shaped telescopic frame 2 are hinged between two adjacent laminates 1, and two corner ends on the other side slide in the sliding grooves 101 opened on the corresponding laminates 1 respectively, so that the X-shaped telescopic frame 2 expands, and further adjusts the distance between two adjacent laminates 1.

[0030] In an embodiment of the present invention, please refer to Figure 1 and Figure 2 , a number of limiting blocks 41 are evenly installed on both sides of the installation groove 102 of the laminate 1, and the number of limiting blocks 41 is in sliding fit with the vertical plates of the U-shaped frame 42.

[0031] It should be noted that: when the U-shaped frame 42 slides in the installation groove 102, the limiting blocks 41 are used for auxiliary support to improve the support strength of the U-shaped frame 42 and facilitate climbing.

[0032] In an embodiment of the present invention, please refer to Figure 1 and Figure 2 , among a number of the laminates 1, support feet 5 are fixedly installed at the four corners of the bottom of the lowermost laminate 1, and safety guardrails 6 are symmetrically installed on the upper surface of the uppermost laminate 1.

[0033] It should be noted that: in this way, the bottom layer board 1 is supported by the supporting feet 5. Further, a locking universal wheel (not shown in the figure) can be installed at the bottom of the supporting feet 5 to facilitate later pushing and transferring. A protective railing 6 is arranged on the top layer board 1 to provide safety protection during elevated construction.

[0034] The working principle of the hanger with a locking function provided by the present utility model is as follows:

[0035] When it is needed to be used, move the scaffolding to the construction site, and then control the hydraulic rods 3 between the respective layer boards 1 to start, driving the corresponding X-shaped telescopic frames 2 to expand, so as to adjust the distance between two adjacent layer boards 1, thereby adjusting the scaffolding to an appropriate height. After adjustment, rotate the handle 44 of the stair mechanism 4 on each layer board 1 to drive the lead screw 43 to rotate, thereby driving the U-shaped frame 42 to slide outwards along the installation groove 102, so as to slide out from one side of the layer board 1. After sliding out, flip the rectangular frame 451, and then turn the threaded sleeve 453 to drive the two screw rods 454 to drive the limiting rods 455 to extend in. After being inserted and matched with the limiting grooves 401 opened on the vertical plates of the corresponding lower U-shaped frames 42, the construction of the stair mechanism 4 is completed, so as to facilitate climbing through the tread board 452 when going up and down the scaffolding. The whole scaffolding is convenient to stretch and fold, and the climbing is safe and easy.

[0036] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the description and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
