Description

Technical Field

[0001] This utility model relates to the field of ladder technology, specifically to a ladder with high stability. Background Technology

[0002] Ladders are frequently used in construction projects. Currently, there are simple ladders and modular scaffolding ladders.

[0003] Publication (Announcement) No.: CN220849550U discloses a construction ladder with high stability, including a base plate, a positioning frame on the top of the base plate, a ladder assembly on the base plate and located inside the positioning frame, and a fixing component on the ladder assembly; the ladder assembly includes a base plate located inside the positioning frame, and a movable ladder is movably installed on the base plate; the fixing component includes a suction cylinder fixedly installed on the top of the base plate and located on one side of the movable ladder, a traction column movably installed on the top of the suction cylinder, a T-shaped handle at the top of the traction column, and an elastic piston plate fixedly installed at the bottom of the traction column.

[0004] In existing technologies, the anti-slip measures used during construction have insufficient safety in their technical structure, making them prone to slipping; and the adjustment of the anti-slip structure requires a long adjustment time, affecting the efficiency of the ladder.

[0005] Therefore, a ladder with high stability is needed. Utility Model Content

[0006] In view of the problems existing in the prior art, the present invention provides a ladder with high stability, thereby solving the technical problems mentioned above.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a highly stable climbing ladder, comprising a climbing ladder and an anti-slip base assembly. The climbing ladder and the anti-slip base assembly are fixedly installed via a hinged base. The anti-slip base assembly includes a base plate with a limiting through hole in the center. Shaft grooves are respectively provided at both ends of the limiting through hole. A limiting plate is installed inside the limiting through hole. Both ends of the limiting plate are rotatably installed in the shaft grooves via rotating shafts. Four fixing plates are symmetrically arranged on both sides of the center of the limiting plate. The base plate is located in the fixing... A receiving groove is provided at the bottom of the plate. The bottom of the fixed plate is connected to the receiving groove by a spring. Positioning pins are evenly distributed at the bottom of the limiting plate. The positioning pins lift the fixed plate by the extension and contraction of the spring, causing the limiting plate to rise. When the ladder is in the initial state, the positioning pins retract into the limiting through hole. A pin groove is provided at the top edge of the limiting plate. A guide rail base is provided at the pin groove on the bottom plate. A pin plate is slidably installed inside the guide rail base. The pin plate is slidably inserted into the pin groove to press down the limiting plate and make the positioning pins insert into the ground.

[0008] Preferably, the limiting through hole is set in a "U" shape.

[0009] Preferably, an anti-slip plate is provided on the bottom of the base plate on the side opposite to the limiting through hole.

[0010] Preferably, the ladder has handrails symmetrically arranged on both sides and hooks at the top.

[0011] In summary, this utility model provides a highly stable ladder. During use, pressing the limiting plate with your foot causes the positioning pin to extend from the limiting through-hole and contact the ground. Moving the pin plate mounted on the guide rail base causes the pin plate to slide into the pin groove of the limiting plate, allowing the positioning pin to engage with the ground. The base plate features a wide U-shaped distribution of positioning pins on the side of the ladder in use, effectively positioning the ladder relative to the ground. This ensures stable use of the ladder, prevents slippage, enables rapid positioning of the ladder's adjustment structure, and improves the efficiency of ladder use. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figures 1 to 5 As shown:

[0020] This utility model is a highly stable climbing ladder, including a climbing ladder 1 and an anti-slip base plate assembly 2. The climbing ladder 1 and the anti-slip base plate assembly 2 are fixedly installed by a hinged base 3. The anti-slip base plate assembly 2 includes a base plate 4, a limiting through hole 5 in the middle of the base plate 4, and shaft grooves 6 at both ends of the limiting through hole 5. A limiting plate 7 is installed inside the limiting through hole 5. Both ends of the limiting plate 7 are rotatably installed in the shaft grooves 6 by a rotating shaft 11. Four fixing plates 12 are symmetrically arranged on both sides of the middle of the limiting plate 7. A receiving groove 13 is opened at the bottom of the fixing plate 12 on the base plate 4. The bottom of 12 is connected to the receiving groove 13 by spring 15. Positioning pins 14 are evenly distributed at the bottom of the limiting plate 7. The positioning pins 14 lift the fixing plate 12 by the extension and retraction of spring 15, so that the limiting plate 7 is raised. When the ladder 1 is in the initial state, the positioning pins 14 are retracted into the limiting through hole 5. A pin groove 16 is opened at the top edge of the limiting plate 7. A guide rail base 17 is set at the pin groove 16 on the bottom plate 4. A pin plate 21 is slidably installed inside the guide rail base 17. The pin plate 21 is slidably inserted into the pin groove 16 to press down the limiting plate 7 and make the positioning pins 14 insert into the ground.

[0021] To address the technical problem of insufficient safety in existing anti-slip positioning structures, this patent employs the following structure: A ladder 1 and an anti-slip base plate assembly 2 are fixedly installed via a hinged base 3. The anti-slip base plate assembly 2 includes a base plate 4. A limiting through hole 5 is formed on one side of the ladder 1 in the inclined direction. Shaft grooves 6 are located at both ends of the limiting through hole 5. A limiting plate 7 is installed inside the limiting through hole 5. Both ends of the limiting plate 7 are rotatably installed in the shaft grooves 6 via rotating shafts 11, allowing the limiting plate 7 to rotate within the limiting through hole 5. Fixing plates 12 are symmetrically arranged on both sides of the middle of the limiting plate 7. A receiving groove 13 is formed at the bottom of the fixing plate 12 on the base plate 4. The fixing plate 12 is connected to the receiving groove 13 via a spring 15, thus achieving the limiting plate... 7. In the initial state, the spring 15 elastically lifts the limiting plate 7, allowing the evenly distributed positioning pins 14 at the bottom to retract into the limiting through hole 5, ensuring safe storage. During use, pressing the limiting plate 7 with your foot causes the positioning pins 14 to extend out of the limiting through hole 5 and contact the ground. Moving the pin plate 21 mounted on the guide rail base 17 causes the pin plate 21 to slide into the pin groove 16 of the limiting plate 7, allowing the positioning pins 14 to engage with the ground. When using the ladder 1, the base plate 4 has a U-shaped distribution of positioning pins 14 on the side where the ladder 1 is used, positioning the ladder 1 relative to the ground. This ensures stable use of the ladder 1, prevents slippage, enables quick positioning of the ladder 1's adjustment structure, and improves the efficiency of the ladder 1.

[0022] In at least one embodiment, the positioning pins 14 are distributed over a large U-shaped range by setting the limiting through hole 5 in a "U" shape, which increases the positioning stability of the ladder 1.

[0023] In at least one embodiment, in order to increase the stability of the ladder 1, an anti-slip plate 22 is provided on the bottom of the base plate 4 on the side opposite to the limiting through hole 5.

[0024] In at least one embodiment, to increase the safety of using the ladder 1, handrails 23 are symmetrically arranged on both sides of the ladder 1 and hooks 24 are arranged on the top. The arrangement of hooks 24 increases the stability of the ladder 1 and increases the safety of use.

[0025] The embodiments described in this utility model are for illustrative purposes only and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutions that can be conceived by those skilled in the art are all within the protection scope of this utility model.
