[0018] Here, it should be noted that the functions and methods involved in the present invention are merely conventional adaptive applications of the prior art. Therefore, the improvement of the present invention on the prior art is essentially the connection relationship between the hardware, rather than the functions and methods themselves. That is, although the present invention involves some functions and methods, it does not include improvements to the functions and methods themselves. The description of the functions and methods in the present invention is to better illustrate the present invention so as to better understand the present invention.

[0019] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0020] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0021] See also Figure 1 to Figure 4The present application discloses a ladder with good stability, comprising a main ladder 1 and side support movable arms, which are arranged on both sides of the main ladder 1 and include a base 3 and a support arm 2. The lower end of the base 3 is rotatably connected to the bottom of the main ladder 1, and the upper end of the base 3 is rotatably connected to the lower end of the support arm 2. The upper end of the support arm 2 is rotatably connected to the main ladder 1 and can slide vertically along the main ladder 1.

[0022] Under normal circumstances, the side support movable arms are vertically arranged on both sides of the main ladder 1 and are in a folded state; when in use, the upper end of the support arm 2 is slid downward, and the connection point between the lower end of the support arm 2 and the upper end of the base 3 is rotated away from the main ladder 1 until the base 3 is rotated to a horizontal state. The support arm 2 is in an inclined state, and the support arms 2 on both sides play a supporting role, thereby improving the stability and safety of the ladder.

[0023] In order to facilitate the sliding of the support arm 2 , sliding grooves 12 are provided along both sides of the main ladder 1 , and the upper end of the support arm 2 is slidably fitted in the sliding grooves 12 .

[0024] Specifically, it also includes a slider assembly 4, which includes a slider body 41 and a connecting portion 42 connected to the slider body 41, the slider body 41 is slidably fitted in the slide groove 12, the connecting portion 42 extends out of the slide groove 12, and is rotatably connected to the upper end of the support arm 2 through a first rotating shaft 5 installed on the connecting portion 42, the lower end of the support arm 2 is rotatably connected to the upper end of the base 3 through a second rotating shaft, and the lower end of the base 3 is rotatably connected to the side of the main ladder 1 through a third rotating shaft.

[0025] By sliding the slider body 41 downward, the support arm 2 is driven to slide downward. Since the upper end of the support arm 2 and the lower end of the base 3 are both rotatably connected to the main ladder 1, the lower end of the support arm 2 and the upper end of the base 3 are driven to move in a direction away from the main ladder 1. The base 3 rotates to a horizontal state, and the support arm 2 rotates to an inclined state to provide auxiliary support for the main ladder 1.

[0026] In order to lock the slider assembly 4, a locking assembly is also included. A positioning slot 11 is horizontally provided on the slide groove 12 for limiting the sliding of the slider body 41. The locking assembly is installed corresponding to the positioning slot 11, and includes a spring sheet 61 and a spring 62. The upper and lower ends of the spring sheet 61 are both installed in the slide groove 12 and arched toward the direction of the positioning slot 11; the spring 62 is installed between the spring sheet 61 and the slide groove 12, one end of which abuts against the slide groove 12, and the other end abuts against the spring sheet 61.

[0027] When the slider assembly 4 slides to the locking assembly, it is gradually pushed toward the outside of the slide groove 12 under the action of the spring sheet 61 and is locked.
