However, on steps or uneven places, its use is limited or it cannot be used normally. The existing patent application number is 202220644409.7, which discloses a ladder adjusting support foot. Aiming at the problem that in the prior art, an extension device is generally used for movement in an A-frame ladder, and the extension device needs to be directly extended to the end to be locked and cannot be adjusted to any length according to requirements, the following solution is proposed. It includes a telescopic rod and an A-frame ladder. A fitting frame is slidably sleeved on the outer wall of the telescopic rod.

[0035] In the present utility model, the stepless adjustment component 3 includes a mounting base 31, a telescopic rod 32, a spring 35, and a plurality of locking plates 34. The mounting base 31 is fixed to the outside of the fixed frame 21. The telescopic rod 32 vertically penetrates through the mounting base 31. The plurality of locking plates 34 are arranged around the telescopic rod 32 and are in contact with the outer wall of the telescopic rod 32.

When the plurality of sliding locking plates 34 are toggled downward through the opening 311, the limiting plate 33 abuts against the locking plate 34 to make the locking plate 34 in a horizontal state for convenient adjustment. When the locking plate 34 is released, the spring 35 pushes the locking plate 34 to move along the limiting plate 33 into an inclined state, and the locking plate 34 is in contact with the outer wall of the telescopic rod 32 to fix the telescopic rod 32 and prevent the telescopic rod 32 from moving.

[0036] In the present utility model, the fixed frame 21 is provided with a plug-in groove 211, and the mounting base 31 is provided with an L-shaped plug-in plate 312. The plug-in plate 312 is slidably inserted into the plug-in groove 211. The fixed frame 21 is symmetrically provided with through holes, and the through holes are connected with a plug pin 24. The plug pin 24 penetrates through the symmetrical through holes and is in contact with the bottom wall of the plug-in plate 312. The plug pin 24 is connected with a U-shaped limiting member 25. One end of the U-shaped limiting member 25 is rotatably connected to one end of the plug pin 24, and the other end is clamped with the other end of the plug pin 24. After the fixed frame 21 is installed, the mounting base 31 can slide upward from the bottom of the fixed frame 21, so that the plug-in plate 312 is slidably inserted into the plug-in groove 211. After sliding in place, the plug pin 24 is inserted. The plug pin 24 passes through the two through holes and is in contact with the bottom of the plug-in plate 312. The U-shaped limiting member 25 is rotated to be clamped with the other end of the plug pin 24 to limit the plug pin 24, and the installation can be quickly and conveniently fixed. When the leveling device or storage is not required in the usage environment of the ladder 1, as long as the clamped U-shaped limiting member 25 is removed and then the plug pin 24 is pulled out, the mounting base 31 can be quickly and conveniently taken out by sliding downward. After the fixed frame 21 is installed, it occupies a small space and can be permanently installed on the ladder 1 without being removed. With this fixed frame 21, the mounting base 31 and the support component 4 can be quickly and conveniently installed, providing convenience.

[0037] In the present utility model, the support member 4 includes a connecting column 41, a rotating head 42 and a fixing plate 43. The connecting column 41 is detachably connected to the telescopic rod 32.

The connecting column 41 is provided with internal threads, and the lower end of the telescopic rod 32 is provided with external threads that fit the internal threads. The connecting column 41 is connected to the telescopic rod 32 through the threads. The shape of the rotating head 42 is spherical, and the opening 311 of the groove of the fixing plate 43 gradually decreases, which limits the spherical rotating head 42. The fixing plate 43 is a rubber plate, and the bottom of the fixing plate 43 is provided with annular anti-slip lines. Through the cooperation of the connecting column 41, the spherical rotating head 42 and the fixing plate 43 with a groove, the position of the rotating head 42 on the fixing plate 43 can be adjusted according to the placement angle of the ladder 1, so that the bottom of the fixing plate 43 contacts the ground, and the contact area remains unchanged, improving the stability of use.

[0038] The implementation principle of a stepless adjustable leveler installed on the side of the ladder foot in the present utility model is as follows:

[0039] Place the backing plate 22 inside the ladder 1, then align the mounting seat 31 with the backing plate 22, and insert the fixing bolt 23 to connect the fixing frame 21, the ladder 1 and the backing plate 22, and then tighten the nut. When the adjustment is not required in the usage scenario of the ladder 1, only install the fixing frame 21.

[0040] When the leveling is required in the usage scenario of the ladder 1, the mounting seat 31 is slidably installed on the fixing frame 21, the plug-in plate 312 slides in the plug-in slot 211, and then insert the pin 24 through the bottom of the plug-in plate 312. The pin 24 fixes the plug-in plate 312 in the plug-in slot 211, and then rotate the U-shaped limiting member 25 to engage with the pin 24 to prevent the pin 24 from loosening during use.

[0041] During use, first place the ladder 1 at the position to be used. The fixing plate 43 contacts the ground. The fixing plate 43 rotates through the spherical rotating head 42 to make the fixing plate 43 flush with the ground. The adjustment process is fast and convenient. The freely rotatable rotating head 42 ensures the use environment of the ladder 1 at different angles and uneven supporting surfaces. Further, the bottom of the fixing plate 43 is provided with annular anti-slip lines.

[0042] Then, pass the finger through the opening 311 and push the plurality of locking plates 34 downward to move, and push the spring 35 to compress. When the locking plates 34 are in a horizontal state, move the telescopic rod 32 up and down to a suitable position. The telescopic rod 32 drives the fixed disk 43 to move. After moving in place, release the plurality of locking plates 34. The spring 35 resets and pushes the locking plates 34 to contact the limiting plate 33 and is arranged obliquely along the limiting plate 33, so that the inner sides of the plurality of locking plates 34 contact the outer side of the telescopic rod 32, realizing the function of locking and fixing the telescopic rod 32. Adjust according to the scenario of the ladder 1 and the ground to ensure the stability of the ladder 1 and improve the high-authority coefficient.

[0043] The above has made an exemplary description of the present invention in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
