[0019] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show typical embodiments of the present invention.

[0020] Embodiment 1:

[0021] like Figure 1-4 As shown, a glass fiber reinforced plastic folding ladder of the utility model comprises a ladder body 1, a folding assembly 2 is provided on the top surface of the ladder body 1, and an anti-skid assembly 3 is fixed to the bottom surface of the ladder body 1, the folding assembly 2 comprises a U-shaped block 201 fixed to the surface of the ladder body 1, and a sleeve 202 is fixed to the side surface of the U-shaped block 201, an L-groove 203 is provided on the surface of the sleeve 202, and an arc groove 204 is provided on the inner wall of the L-groove 203, a spring 205 is sleeved inside the sleeve 202, and a boss 206 is movably connected inside the sleeve 202, a sliding column 207 is fixed to the surface of the boss 206, the folding assembly 2 also comprises an annular block 1 208 fixed to the surface of the ladder body 1, and an annular block 209 is installed on the surface of the annular block 1 208 through a rotating shaft, a connecting ladder 210 is fixed to the surface of the annular block 209, and a through hole 211 is provided on the side surface of the connecting ladder 210.

[0022] like Figure 1-4 As shown, four groups of U-shaped blocks 201 are provided, and the U-shaped blocks 201 are symmetrically arranged with each other. The U-shaped blocks 201 and the ladder body 1 form a fixed structure through bolts.

[0023] like Figure 1-4 As shown, the surface of the boss 206 contacts the inner wall of the sleeve 202 , and the side surface of the spring 205 contacts the surface of the boss 206 .

[0024] like Figure 1-4 As shown, the diameter of the side surface of the protruding column 206 is equal to the inner diameter of the through hole 211 , and the surface of the sliding column 207 contacts the inner wall of the L-groove 203 .

[0025] During implementation, when folding is required, the sliding column 207 is used to drive the protruding column 206 to slide, and the protruding column 206 is rotated at the same time. Since the surface of the sleeve 202 is provided with an L-groove 203 and an arc groove 204, the sliding column 207 can be limited, and the connecting ladder 210 is rotated at the same time. When the connecting ladder 210 is rotated to a suitable position, the sliding column 207 is rotated, and the spring 205 pushes the protruding column 206 and the sliding column 207 to slide, so that the protruding column 206 contacts the through hole 211 on the surface of the connecting ladder 210, thereby folding the ladder body 1. At the same time, it is convenient to fold and easy to carry.

[0026] Embodiment 2:

[0027] like Figure 1-4 As shown, based on the first embodiment, the utility model provides a technical solution: the anti-skid component 3 includes a connecting block 301 arranged on the side surface of the ladder body 1, and a connecting plate 302 is fixed to the bottom surface of the connecting block 301, an anti-skid pad 303 is fixed to the bottom surface of the connecting plate 302, an arc block 304 is fixed to the side surface of the connecting plate 302, and an L block 305 is fixed to the top surface of the connecting plate 302.

[0028] like Figure 1-4 As shown, a fixed block 306 is fixed on the surface of the L block 305, and a threaded column 307 is threadedly connected inside the fixed block 306, a round block 308 is fixed to the bottom surface of the threaded column 307, and a limited insert drill 309 is fixed to the bottom surface of the round block 308, and an auxiliary insert drill 310 is fixed to the bottom surface of the round block 308.

[0029] During implementation, since the connecting block 301 and the ladder body 1 are a rotating structure, when the inclination angle of the ladder body 1 is too large or too small, the connecting plate 302 is always in contact with the ground. The connecting plate 302 is provided with an anti-slip pad 303 to improve the anti-slip effect. By rotating the threaded column 307, the threaded column 307 pushes the limiting insert 309 and the auxiliary insert 310 to slide, so that the limiting insert 309 and the auxiliary insert 310 are in contact with the ground, further improving stability.

[0030] The advantages of this technical solution in practical applications include but are not limited to the following:

[0031] 1. The folding assembly 2 is provided with a sleeve 202 and a boss 206 inside. When folding is required, the boss 206 is slid and the connecting ladder 210 is rotated at the same time. The connecting ladder 210 is rotated to a suitable position and the boss 206 is slid at the same time, so that the ladder body 1 can be folded. At the same time, the folding is convenient and easy to carry.

[0032] 2. By arranging the connecting plate 302 and the anti-slip pad 303 inside the anti-slip component 3, and since the connecting block 301 and the ladder body 1 are a rotating structure, the stability of the connecting plate 302 is improved. At the same time, by rotating the threaded column 307, the threaded column 307 pushes the limiting plunger 309 to slide, thereby further improving the stability.

[0033] When folding is required in the present technical solution, the sliding column 207 is slid, and the sliding column 207 drives the protruding column 206 to slide, and the protruding column 206 is rotated at the same time. Since the surface of the sleeve 202 is provided with an L groove 203 and an arc groove 204, the sliding column 207 can be limited, and the connecting ladder 210 is rotated at the same time. When the connecting ladder 210 is rotated to a suitable position, the sliding column 207 is rotated, and the spring 205 pushes the protruding column 206 and the sliding column 207 to slide, so that the protruding column 206 contacts the through hole 211 on the surface of the connecting ladder 210. Therefore, it is convenient to fold the ladder body 1, and it is convenient to fold and easy to carry. Since the connecting block 301 and the ladder body 1 are rotating structures, when the ladder body 1 is tilted too much or too little, the connecting plate 302 is always in contact with the ground. The connecting plate 302 is provided with an anti-skid pad 303 to improve the anti-skid effect. By rotating the threaded column 307, the threaded column 307 pushes the limiting insert 309 and the auxiliary insert 310 to slide, so that the limiting insert 309 and the auxiliary insert 310 are in contact with the ground, further improving stability.

[0034] The above are only exemplary embodiments of the present disclosure and cannot be used to limit the scope of the present disclosure. That is, any equivalent changes and modifications made according to the teachings of the present disclosure are still within the scope of the present disclosure. This application is intended to cover any variation, use or adaptive change of the present disclosure, which follows the general principles of the present disclosure and includes common knowledge or conventional technical means in the technical field not recorded in the present disclosure.
