Detailed Implementation
[0027] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.
[0028] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.
[0030] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0031] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.
[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0033] like Figures 1-7 The diagram illustrates an insulated ladder for power construction according to an embodiment of this disclosure. It includes four first insulating legs 1, arranged in two groups. Each of the four first insulating legs 1 has an adjusting assembly at its top, with six adjusting assemblies arranged in three groups. Each of the two groups of adjusting assemblies has a support assembly at its top. Each support assembly includes a first connecting leg 2 slidably connected to the outside of the adjusting assembly. Seven first foot pedals 3 are fixedly connected between two first connecting legs 2, arranged in two groups. The second group of first foot pedals... Step 3 is fixedly connected between two first insulating legs 1. A rotating rod 7 is fixedly connected between two first connecting legs 2. Two second connecting legs 4 are rotatably connected to the outside of one rotating rod 7. Two second insulating legs 5 are rotatably connected to the outside of the second rotating rod 7. A second foot pedal 6 is fixedly connected between two second insulating legs 5. There are seven second foot pedals 6. The seven second foot pedals 6 are divided into two groups. The second group of second foot pedals 6 is fixedly connected between two second connecting legs 4. The ends of the two second insulating legs 5 are fixedly connected to the ends of two groups of adjustment components. The outside of the two groups of adjustment components is slidably connected to the inside of the second foot pedal 6.
[0034] The device utilizes four first insulating legs 1 and an adjusting assembly to support the position of the first connecting leg 2, which in turn supports the second insulating leg 5 and the second connecting leg 4, and consequently the first footrest 3 and the second footrest 6. This allows construction workers to stand on top of the second insulating leg 5, the second connecting leg 4, and the second footrest 6, enabling multiple workers to perform the work and improving efficiency. Furthermore, one of the first connecting legs 2 can be rotated using a rotating rod 7, transforming the device into an A-frame ladder. The second connecting leg 4 can be rotated in conjunction with the second rotating rod 7, transforming the device into a single ladder, thus enhancing the overall adaptability and practicality of the device.
[0035] like Figure 3 As shown, the adjustment assembly includes a first connecting plate 8 fixedly connected to the top of the first insulating leg 1. A first screw 9 is fixedly connected to the top of the first connecting plate 8. Two sets of first screws 9 are slidably connected inside the first connecting leg 2, and another set of first screws 9 is slidably connected to the inside of the second foot pedal 6. A nut 10 is threadedly connected to the outside of the first screw 9.
[0036] By rotating the nut 10, the nut 10 is rotated outside the first screw 9, thereby abutting against the first connecting leg 2. This limits the length of the first screw 9, controls the distance between the first insulating leg 1 and the first connecting leg 2, and thus controls the height of the device.
[0037] like Figure 4 As shown, both the first insulating leg 1 and the second insulating leg 5 are provided with limiting components at their ends. The limiting component at the end of the first insulating leg 1 is larger than the limiting component at the end of the second insulating leg 5. The limiting component includes a rotating seat 13 rotatably connected to the outside of the first insulating leg 1. An anti-slip seat 11 is fixedly connected to the end of the rotating seat 13, and a first limiting plate 12 is fixedly connected to the end of the anti-slip seat 11.
[0038] The rotating seat 13 ensures that the anti-slip seat 11 always faces the ground after the first insulating leg 1 changes angle, thereby reducing the possibility of side slippage during use.
[0039] like Figure 5 As shown, a support assembly is provided on the outer side of the first connecting leg 2. There are four support assemblies. The support assembly includes a first connecting ring 14 fixedly connected to the outer side of the first connecting leg 2. A second screw 15 is movably connected inside the first connecting ring 14. A screw cylinder 16 is threadedly connected to the outer side of the second screw 15.
[0040] By rotating the screw barrel 16, the second screw 15 can be extended further.
[0041] like Figure 5As shown, the support assembly also includes a connecting rod 17 rotatably connected to the bottom of the screw barrel 16. A hook 18 is fixedly connected to the end of the connecting rod 17. A second connecting ring 31 is movably connected inside the hook 18. There are four second connecting rings 31, which are divided into two groups. One group of second connecting rings 31 is fixedly connected to the bottom of the second connecting leg 4, and the other group of second connecting rings 31 is fixedly connected to the bottom of the second insulating leg 5.
[0042] Specifically, by attaching the hook 18 to the second connecting ring 31 and then rotating the screw 16 to tighten the second screw 15, the first connecting leg 2 and the second insulating leg 5 can be supported.
[0043] like Figure 7 As shown, a first connecting component is provided on the outer side of the second connecting leg 4. The first connecting component includes a limiting block 26 fixedly connected to the outer side of the second connecting leg 4. The inside of the limiting block 26 is slidably connected to the outer side of two of the first screws 9. Two second rotating shafts 27 are rotatably connected to the outer side of the limiting block 26. A second rotating plate 28 is fixedly connected to the outer side of the second rotating shaft 27.
[0044] Specifically, the first screw 9 is placed inside the limiting block 26, and then the second rotating plate 28 is rotated.
[0045] like Figure 7 As shown, the first connecting assembly also includes a second retaining ring 29 fixedly connected to the outside of the second rotating plate 28, a second pressing plate 30 fixedly connected to the outside of the second retaining ring 29, and the second pressing plate 30 slidably connected to the outside of the limiting block 26.
[0046] The rotation of the second rotating plate 28 drives the rotation of the second retaining ring 29, which in turn drives the movement of the second pressing plate 30, thereby clamping the first screw 9. Then, rotating the nut 10 presses the second pressing plate 30, thereby restricting the position of the second retaining ring 29 and the first screw 9, allowing the device to be folded up and converted into an A-frame ladder.
[0047] like Figure 6 As shown, auxiliary components are provided on the outer sides of the two first screws 9. The auxiliary components include a second limiting plate 19 that is slidably connected to the outer side of the first screw 9. A second connecting plate 20 is fixedly connected to the bottom of the second limiting plate 19. A third limiting plate 21 is fixedly connected to the bottom of the second connecting plate 20. The interior of the third limiting plate 21 is slidably connected to the outer side of the other two first screws 9.
[0048] The sliding of the second limiting plate 19 can drive the second connecting plate 20 to move, which in turn can drive the third limiting plate 21 to move, so that the third limiting plate 21 can wrap around the first screw 9.
[0049] like Figure 6 As shown, a second connecting assembly is provided on the outer side of the third limiting plate 21. The second connecting assembly includes two first rotating shafts 22 that are rotatably connected to the outer side of the third limiting plate 21. A first rotating plate 23 is fixedly connected to the outer side of the first rotating shafts 22.
[0050] The first screw 9 is wrapped around the outside by the third limiting plate 21, and then the first rotating plate 23 is rotated.
[0051] like Figure 6 As shown, the second connecting assembly also includes a first retaining ring 24 fixedly connected to the end of the first rotating plate 23, a first pressing plate 25 fixedly connected to the outside of the first retaining ring 24, and the first pressing plate 25 slidably connected to the outside of the third limiting plate 21.
[0052] The rotation of the first rotating plate 23 causes the first retaining ring 24 to clamp the first screw 9 and move the first pressing plate 25. Then, the nut 10 is rotated to press the first pressing plate 25, thereby restricting the position of the first retaining ring 24 and the first screw 9. This allows the device to be converted into a single ladder, making it easier to use and transport.
[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
