Specific embodiments

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: a scaffolding base, including a base body 1, the base body 1 is a hollow rectangular frame structure, a jack 101 is opened on the upper surface of the base body 1, and adjustable legs 2 are provided at the four corners of the inner wall of the bottom of the base body 1. Each adjustable leg 2 includes a leg body 201, the leg body 201 is slidably connected in the corresponding installation sliding hole 202, and the four installation sliding holes 202 are respectively opened at the four corners of the inner wall of the bottom of the base body 1. A thread groove 203 is opened inwards on the top surface of the leg body 201, an adjusting screw 204 is threadedly connected in the thread groove 203, the adjusting screw 204 is rotatably connected in a through hole opened on the surface of the corresponding extended installation part 205, one end of the adjusting screw 204 is fixedly connected with a first adjusting knob 209, and the four extended installation parts 205 are integrally provided on both sides at both ends of the upper surface of the base body 1.

[0022] Please refer to Figure 2 and Figure 4 , a limit socket 102 is integrally provided at the center of the inner wall of the bottom of the base body 1 below the jack 101.

[0023] By providing the limit socket 102 on the inner wall of the bottom of the base body 1, the scaffolding can be further limited after being inserted into the jack 101, avoiding independent angular deflection of the whole scaffolding in the jack 101 and causing bending, and improving the stability during use.

[0024] Please refer to Figure 2 and Figure 3 On the outer wall of each leg body 201, a number of limiting convex strips 206 are integrally arranged in a uniformly distributed annular shape. On the inner wall of each mounting slide hole 202, a number of limiting grooves 207 corresponding one-to-one to the limiting convex strips 206 are provided. Each limiting convex strip 206 is slidably connected in the corresponding limiting groove 207.

[0025] The cooperation of the limiting convex strips 206 and the limiting grooves 207 can limit the leg body 201, so that the leg body 201 can only slide up and down in the mounting slide hole 202 and cannot rotate itself. Therefore, when the adjusting screw 204 is rotated by the first adjusting knob 209, the leg body 201 can only adjust the length extending out of the mounting slide hole 202, so as to adjust the overall height and levelness of the base body 1 to adapt to the complex ground conditions at the construction site.

[0026] Furthermore, on the bottom surface of each leg body 201, an anti-slip pad 208 is provided, and a number of anti-slip convex points are provided on the surface of the anti-slip pad 208.

[0027] By providing the anti-slip pad 208 at the bottom of the leg body 201, the friction between it and the ground can be increased, and the stability can be improved during support. At the same time, by providing a convex point structure on the surface of the anti-slip pad 208, the roughness can be further increased to enhance the friction.

[0028] Please refer to Figure 4 On the upper surface of the base body 1, a limiting and stabilizing mechanism 3 is further provided. The limiting and stabilizing mechanism 3 includes two chutes 301 opened at both ends of the upper surface of the base body 1. One end of a connecting rod 302 is slidably installed in each chute 301. The other ends of the two connecting rods 302 are respectively fixedly connected with clamping blocks 303, and both clamping blocks 303 are connected with an opening and closing mechanism.

[0029] Through the opening and closing mechanism, the two connecting rods 302 can be driven to perform synchronous reverse sliding displacements in the corresponding chutes 301, so as to adjust the distance between the two clamping blocks 303. After the scaffolding rod body is connected to the base body 1, the two clamping blocks 303 can clamp and fix the scaffolding to prevent it from separating from the base body 1, further improving the stability. At the same time, it can also cooperate with the limiting socket 102 to further limit the scaffolding.

[0030] Furthermore, the two clamping blocks 303 are arranged oppositely, and a rubber cushion is provided on the inner wall of each clamping block 303.

[0031] By providing a rubber cushion on the inner wall of the clamping block 303, it can not only increase the friction between it and the scaffolding to ensure the limiting stability, but also play a certain degree of protection for the scaffolding.

[0032] Furthermore, the opening and closing mechanism includes two connecting ear plates 304. Each connecting ear plate 304 is fixedly connected to one side surface of the pair of connecting rods 302. Threaded holes are formed in one side surface of each of the two connecting ear plates 304, and the two connecting ear plates 304 are threadedly connected to both ends of the bidirectional threaded rod 305 through the threaded holes. The bidirectional threaded rod 305 is rotatably installed at one end of the bracket 306, and the other end of the bracket 306 is fixedly connected to the upper surface of the base body 1.

[0033] Since the thread directions at both ends of the bidirectional threaded rod 305 are opposite and the two connecting ear plates 304 are respectively threadedly connected to both ends of the bidirectional threaded rod 305, when the bidirectional threaded rod 305 is rotated, the two connecting ear plates 304 will perform synchronous reverse displacement guided by the sliding groove 301, thereby realizing the adjustment of the distance between the two clamping blocks 303.

[0034] Working principle: Insert the socket 101 at the bottom end of the scaffolding into the overall base body 1, and make its bottom end insert into the limit socket 102. Rotate the bidirectional threaded rod 305 to drive the two clamping blocks 303 to move towards each other to clamp and limit the outer wall of the scaffolding. Then, according to the condition of the ground where the base body 1 is placed, rotate the adjusting screw 204 one by one to drive the corresponding leg body 201 to slide and adjust the extended length in the installation sliding hole 202, so that the overall base body 1 can be at an appropriate height and remain horizontal when supported by the four installation leg bodies 201, so as to improve the stability of the support for the scaffolding and reduce potential safety hazards.

[0035] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
