[0033] like Figures 1 to 5As shown, this embodiment provides a lateral adjustment device for an aluminum alloy movable step, comprising: two fixed slide rails 1; a pedal assembly 2, comprising a slider 21, a support shaft 23, a fixed housing 24, and a support plate 25, wherein the slider 21 is slidably connected to the fixed slide rail 1, the support shaft 23 is rotatably connected between the two sliders 21, the fixed housing 24 is fixedly connected to the support shaft 23, the support plate 25 is fixedly connected to the support shaft 23, and the support plate 25 is bolted to the fixed housing 24; and a support assembly 3, comprising a connecting plate 31 and a support rod 32, wherein the connecting plate 31 is fixedly connected to the lower side of the support plate 25, and the support rod 32 is rotatably connected to the connecting plate 31.

[0034] The support plate 25 is provided with anti-slip texture.

[0035] Specifically, the fixed slide rail 1 is provided with multiple connection holes 11.

[0036] In this embodiment, the fixed slide rail 1, the pedal assembly 2, and the support assembly 3 constitute a lateral adjustment device for an aluminum alloy movable step according to this application.

[0037] It should also be noted that this application can be connected and used with equipment such as automobiles and mechanical work platforms.

[0038] In this embodiment, we provide supplementary information, a description of the working principle, and a description of the effects.

[0039] Example 2:

[0040] Specifically, an electric push rod 22 is bolted inside the fixed slide rail 1, and one end of the electric push rod 22 is bolted to the slider 21.

[0041] Specifically, one end of the support shaft 23 extends into the slider 21, and an adjustment plate 26 is fixedly connected to the support shaft 23 located inside the slider 21. Multiple positioning holes are evenly distributed on the adjustment plate 26.

[0042] Specifically, a positioning pin 27 is slidably connected to the side wall of the slider 21. One end of the positioning pin 27 passes through the fixed slide rail 1. A slide groove is provided on the side wall of the fixed slide rail 1. The slide groove is slidably connected to the positioning pin 27. The other end of the positioning pin 27 is slidably connected to the positioning hole.

[0043] Specifically, a spring 28 is provided inside the slider 21, and the two ends of the spring 28 are fixedly connected to the slider 21 and the positioning pin 27, respectively.

[0044] In this embodiment, the electric push rod 22 extends and retracts to drive the slider 21 to slide along the fixed slide rail 1, automatically controlling the extension and retraction of the support plate 25, saving manpower and improving ease of use. The adjustment plate 26 rotates with the support shaft 23, and the positioning hole provides multiple angle positioning points, providing multiple fixed positions for the angle adjustment of the support plate 25 to meet different usage needs. The positioning pin 27 slides along the slide groove and inserts into the positioning hole to fix the adjustment plate 26, quickly locking the rotation angle of the support shaft 23 and ensuring the stability of the angle of the support plate 25. The spring 28 extends and retracts to generate elastic force, driving the positioning pin 27 to automatically reset and insert into the positioning hole, realizing the automatic locking of the positioning pin 27, simplifying the operation steps and improving the adjustment efficiency.

[0045] Example 3:

[0046] Specifically, one end of the support rod 32 is threadedly connected to an adjusting sleeve 33, and the bottom of the support plate 25 is also fixedly connected to a locking seat 34. The bottom of the locking seat 34 is made of elastic material, and the bottom of the locking seat 34 is slidably connected to the adjusting sleeve 33.

[0047] In addition, the other end of the adjusting sleeve is threaded with a support foot, which is a trapezoidal block.

[0048] In this embodiment, the adjusting sleeve 33 rotates along the thread of the support rod 32 to adjust its length, and the locking seat 34 elastically clamps and fixes the adjusting sleeve 33. The bottom of the adjusting sleeve 33 contacts the ground to provide support, enhances the load-bearing stability of the support plate 25, adapts to different ground heights, and improves the load-bearing capacity of the device.

[0049] In actual use, the user first inserts the bolt into the connecting hole 11, and then connects the fixed slide rail 1 to the external equipment with the bolt. Then the electric push rod 22 can be activated. The electric push rod 22 pushes the slider 21 to push out the support plate 25, making it convenient for the user to step on it. When it is necessary to adjust the angle of the support plate 25, such as when moving heavy goods, the positioning pin 27 can be pulled, and then the support plate 25 can be rotated to adjust the angle of the support plate 25. Then the positioning pin 27 is released, and the positioning pin 27 automatically enters the positioning hole under the action of the spring 28, which can lock the angle of the support plate 25. The adjusting sleeve 33 at the bottom of the support plate 25 can be moved, and then the adjusting sleeve 33 can be rotated so that the bottom of the adjusting sleeve 33 contacts the ground to provide auxiliary support for the support plate 25.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
