DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in combination with the drawings in the embodiments of the utility model, and the following embodiments are used to illustrate the utility model, but are not used to limit the scope of the utility model.

[0025] Embodiment 1:

[0026] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 5A carbon fiber folding ladder that is easy to fix includes a folding ladder body 1, which is composed of two sets of step units. Each set of step units has multiple units. Each step unit includes a middle plate 2, an outer side plate 201, an inner side plate 202, and a step 203. Two adjacent middle plates 2 are rotatably connected, two adjacent outer side plates 201 are rotatably connected, and two adjacent inner side plates 202 are rotatably connected. The outer side plate 201 is rotatably connected to the outer side wall of the middle plate 2, and the inner side plate 202 is rotatably connected to the inner side wall of the middle plate 2. The step 203 is fixedly connected to the side wall of the inner side plate 202. A telescopic sleeve 204 is sleeved on the step 203. The step 203 can slide and extend within the telescopic sleeve 204. The telescopic sleeve 204 is provided with a locking component for locking the step 203.

[0027] The middle plate 2, outer plate 201, inner plate 202, and tread 203 of each step unit are all made of carbon fiber plate.

[0028] The outer side plate 201 and inner side plate 202 at the upper end of the folding ladder body 1 are both provided with T-shaped limiting grooves 4; it also includes a reinforcing rib 401, and each end of the reinforcing rib 401 is fixedly connected with a limiting block 402 corresponding to the limiting groove 4, and the limiting block 402 is inserted into the limiting groove 4.

[0029] When using a folding ladder, first choose a stable surface and place the folded ladder on it. A stable surface ensures safety during subsequent operations and prevents the ladder from tipping over and causing danger. Since the adjacent middle plate 2, outer plate 201, and inner plate 202 in each set of steps of the folding ladder body 1 are connected by a flexible and smooth rotation, the user can hold two sets of steps and slowly pull them to the sides to unfold. This rotating connection design makes the unfolding process easy and effortless, reducing the user's physical exertion, and even people with less strength can operate it easily.

[0030] When expanded to (e.g.) Figure 2 After the state shown, first flip the middle plate 2 inward by 90°, and then flip the outer plate 201 inward by 90°. Since the middle plate 2 and outer plate 201 made of carbon fiber are lightweight, the flipping operation is effortless, which greatly improves the convenience of unfolding operation.

[0031] Once the assembly is complete, insert the limiting block 402 on the reinforcing rib 401 into the limiting groove 4 to complete the assembly of the main body 1 of the folding ladder (e.g., Figure 1 As shown in the figure, the cooperation between the limiting block 402 and the limiting groove 4 enhances the stability of the overall ladder structure and ensures the safety of users when working at heights.

[0032] When the folding ladder is not used, first hold the reinforcing rib 401, pull out the limiting block 402 at both ends from the limiting groove 4 on the outer side plate 201 and the inner side plate 202, the plug-in design of the limiting block 402 and the limiting groove 4 makes the disconnection operation easy and simple, and at the same time can reliably enhance the stability of the ladder during use, ensuring safety;

[0033] Then, first turn the outer side plate 201 outward by 90°, and then turn the middle plate 2 outward by 90°. Due to the lightweight characteristics of carbon fiber material, the two turning actions are easily completed, reducing the operation difficulty of the user and improving the folding efficiency. At this time, the middle plate 2, the outer side plate 201 and the inner side plate 202 between adjacent ladder units are in a further foldable state. The user holds the two ladder units respectively, and turns the adjacent middle plate 2, outer side plate 201 and inner side plate 202 towards the middle around the rotating connection part, and finally folds the folding ladder body into a compact form, which is convenient for storage in the corner of the house, the trunk of the car and other small spaces, and is also convenient for carrying and moving to different work sites, solving the problems of difficult storage and inconvenient carrying of traditional ladders.

[0034] When the user faces different working spaces, such as narrow space or needs larger stepping area, the extension length of the stepping plate 203 can be adjusted according to the actual situation. If the space is limited, the stepping plate 203 can be appropriately shortened. If a more stable standing space is needed, the stepping plate 203 can be lengthened. This adjustable stepping plate 203 design further enhances the applicability of the folding ladder in different environments.

[0035] Embodiment 2:

[0036] Referring to Figure 1 、 Figure 2 、 Figure 3 A carbon fiber folding ladder convenient to fix, which is basically the same as embodiment 1, and further includes a fixing bolt 206 threadedly connected to the side wall of the telescopic sleeve 204. One end of the fixing bolt 206 penetrating into the telescopic sleeve 204 abuts against the stepping plate 203.

[0037] When the stepping plate 203 is telescoped to the appropriate position, rotate the fixing bolt 206 so that it penetrates the telescopic sleeve 204 and abuts against the stepping plate 203, thereby limiting the sliding of the stepping plate 203 and achieving the locking of the position of the stepping plate 203. This locking method is convenient to operate and can reliably fix the stepping plate 203, ensuring the safety of the user on the ladder and avoiding the danger caused by accidental sliding of the stepping plate 203.

[0038] A plurality of locking holes 205 are equidistantly formed on the stepping plate 203, and one end of the fixing bolt 206 penetrating into the telescopic sleeve 204 is plugged into the locking hole 205;

[0039] After adjusting the telescopic length of the pedal 203, the fixed bolt 206 is rotated to insert its end into the corresponding locking hole 205, which further enhances the stability of the position locking of the pedal 203 compared with simple abutting, can better bear the weight of the user, prevents the pedal 203 from loosening during use, and improves the reliability and safety of the folding ladder as a whole.

[0040] Embodiment 3:

[0041] With reference to Figure 1 , Figure 2 , Figure 4 A carbon fiber folding ladder convenient to fix, which is basically the same as Embodiment 1, and further, the middle plate 2 at the lower end of the folding ladder body 1 is provided with an anti-skid base 3.

[0042] When the folding ladder is used, the anti-skid base 3 is in contact with the ground, and the anti-skid design increases the friction with the ground, prevents the ladder from sliding during use, and ensures the safety of the user.

[0043] A plurality of adjusting holes 301 are equidistantly formed on the middle plate 2, and the anti-skid base 3 is inserted with a limiting bolt 302 which is threadedly connected with the adjusting hole 301.

[0044] When it is necessary to adjust the position or height of the anti-skid base 3, the limiting bolt 302 is loosened, the anti-skid base 3 is adjusted according to the actual situation, and then the limiting bolt 302 is tightened for fixing, and this adjustable connecting mode can adapt to different ground conditions, further enhances the stability of the ladder placement, and ensures safe use in various complex ground environments.

[0045] The above only describes preferred embodiments of the present application and does not limit the present application in any form, although the present application has been disclosed as above with preferred embodiments, however, it is not intended to limit the present application.
