Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Referring to Figures 1-5, this utility model embodiment discloses an A-frame ladder placed on an inclined ground, comprising:

[0027] The front ladder 1 includes two front support rods 11, with multiple steps 2 between the two front support rods 11. A level 3 is installed on the front ladder 1. The rear ladder 4 includes two rear support rods 41, with multiple steps 2 between the two rear support rods 41. The top of the rear ladder 4 is hinged to the top of the front ladder 1. In this embodiment, the front ladder 1 and the rear ladder 4 form an A-frame ladder, which can be placed directly on the ground without relying on a building. When necessary, the A-frame ladder can be unfolded to obtain a longer ladder, which can increase the height when used. By setting a level 3, the user can observe whether the A-frame ladder is in a vertical state. Level 3 is set on the steps 2 at the bottom of both the front ladder 1 and the rear ladder 4, so that while adjusting the telescopic rod 5, the user can observe whether the steps 2 of the A-frame ladder are in a horizontal state until the steps 2 are adjusted to a horizontal state for the user to use.

[0028] Both the front support rod 11 and the rear support rod 41 are equipped with telescopic rods 5 at their bottoms. The telescopic rod 5 includes a threaded tube 51, a threaded rod 52, and a rotating ring 53. Multiple threaded tubes 51, threaded rods 52, and rotating rings 53 are provided and connected to the front support rod 11 and the rear support rod 41 respectively. The threaded rod 52 is threadedly connected to the threaded tube 51, and the rotating ring 53 is connected to the bottom end of the threaded rod 52. In this embodiment, the axes of the threaded tube 51, threaded rod 52, and rotating ring 53 of the front support rod 11 or the rear support rod 41 are on the same axis. By rotating the rotating ring 53, the rotating ring 53 and the threaded rod 52 are fixedly connected. The threaded rod 52 rotates, thereby enabling the threaded rod 52 to be screwed out or screwed into the threaded tube 51, which can realize the raising and lowering of the rotating ring 53. This allows the height of a single front support rod 11 or rear support rod 41 to be adjusted, thus adjusting the step 2 to a level state for user use on uneven ground.

[0029] A fixing rod 6 is provided at the bottom of the rotating ring 53. The top of the fixing rod 6 is rotatably connected to the rotating ring 53, and the axis of the fixing rod 6 is the same as the axis of the rotating ring 53. In this embodiment, a friction ball is provided at the bottom of the fixing rod 6. The friction ball is made of rubber. When in use, the friction ball rubs against the ground. The friction ball and the fixing rod 6 are fixed in place. Since the fixing rod 6 and the rotating ring 53 are rotatably connected, the length of the telescopic rod 5 can be adjusted by rotating the rotating ring 53.

[0030] Telescopic plates 7 are provided between the fixed rods 6 of the two front support rods 11 and between the fixed rods 6 of the two rear support rods 41.

A spring 705 is provided between the front slider 701 and the rear slider 703. In this embodiment, when the length of the telescopic rod 5 on one side is adjusted, the length of the telescopic plate 7 between the two fixed rods 6 changes and tilts, which can fix the bottom of the front support rod 11 or the two rear support rods 41. At the same time, by setting the spring 705, the length of the telescopic plate 7 can be quickly adjusted, so that the A-frame ladder can be quickly leveled for use by the user.

[0031] Anti-slip pads 706 are provided under both the front panel 71 and the rear panel 72, and the bottom of the anti-slip pads 706 are in frictional contact with the ground. In this embodiment, by providing anti-slip pads 706, the friction between the stepladder and the ground can be increased to protect the user's safety.

[0032] A binding roller 8 is installed on the step 2 of the front ladder 1 and the step 2 of the rear ladder 4. The two binding rollers 8 are connected by a binding strap 9. In this embodiment, by setting the binding strap 9 to connect the two binding rollers 8, it can prevent the front ladder 1 and the rear ladder 4 from opening at a large angle during use, and prevent the angle between the front ladder 1 and the rear ladder 4 from expanding during use, which can effectively ensure the safety of the user.
