Description

Technical Field

[0001] This utility model relates to the field of articulated ladder technology, and in particular to a multifunctional articulated ladder. Background Technology

[0002] Traditional ladders, as common climbing tools, play an important role in daily life and work. They are usually composed of long strips or rungs and are used to help people reach a certain height. The design of traditional ladders is relatively simple, mainly meeting basic climbing needs. In various scenarios such as logistics transportation, construction work, and home repair, ladders are indispensable tools.

[0003] However, traditional ladders have a single function, serving only as climbing tools. This brings many inconveniences in practical applications. In logistics and transportation, workers often need to move items and climb to heights simultaneously. Traditional ladders cannot meet this need, causing workers to frequently change tools. This not only reduces work efficiency but also increases operational difficulty and safety risks. In addition, in decoration work, workers need to work on a stable platform, but traditional ladders cannot provide such a platform, forcing workers to work suspended in mid-air, which poses safety hazards.

The second connecting ladder is hinged to the second connecting ladder and located at one end of the second connecting ladder. The second connecting ladder is hinged to the second support ladder 4 and located at the other end of the second support ladder 4.

[0029] In this embodiment, the casters 5 enable the ladder to move flexibly and adapt to different working environments. Meanwhile, the support plate 6 and support assembly 7 are installed inside the first support leg ladder 1, the first connecting ladder 2, and the second connecting ladder 3, which can be unfolded as needed to form a stable support structure, providing a safe working platform for the user. Furthermore, the anti-slip sleeve 8 design increases the stability and safety of the ladder, effectively preventing the risk of slipping during use. This multi-functional articulated ladder design not only retains the climbing function of a traditional ladder but also expands its application scenarios, achieving a multi-purpose effect and greatly improving work efficiency and ease of use.

[0030] Furthermore, the other end of the first support ladder 1, the other end of the second support ladder 4, both ends of the first connecting ladder 2, and both ends of the second connecting ladder all have folding insertion holes 9 and unfolding insertion holes 10. The other end of the second support ladder 4 also has a handrail insertion hole 11. A first pin 12 is provided between the first support ladder 1 and the first connecting ladder 2, and the first pin 12 is inserted into the folding insertion hole 9 between the first support ladder 1 and the first connecting ladder 2. A second pin 13 is provided between the first connecting ladder 2 and the second connecting ladder, and the second pin 13 is inserted into the folding insertion hole 9 between the first connecting ladder 2 and the second connecting ladder. A third pin 14 is provided between the second connecting ladder and the second support ladder 4, and the third pin 14 is inserted into the folding insertion hole 9 between the second connecting ladder and the second support ladder 4.

[0031] In this embodiment, by using the folding socket 9 and the unfolding socket 10, and configuring corresponding pins, the ladder can be quickly folded or laid flat as needed, facilitating storage and transportation. At the same time, the handrail socket 11 can provide a fixing point for the second leg ladder 4 when the ladder is on a flatbed, thereby allowing the second leg ladder 4 to be used as a handrail. This design enables the ladder to quickly change its form in different usage scenarios, improving work efficiency and flexibility.

[0032] Furthermore, a first magnetic absorbing piece 15 is provided at both the folding socket 9 and the unfolding socket 10, and a second magnetic absorbing piece 16 is provided on the first pin 12, the second pin 13 and the third pin 14, and the first magnetic absorbing piece 15 and the second magnetic absorbing piece 16 are magnetically connected.

[0033] In this embodiment, the magnetic connection between the pin and the socket is achieved through the first magnetic absorbing piece 15 and the second magnetic absorbing piece 16. This design not only makes it easier to insert and remove the pin, but also improves the stability and safety of the connection. During use, even if it is affected by external force, the pin is not easy to fall off, thereby ensuring the overall stability of the ladder and the safety of the user.

[0034] Furthermore, the support assembly 7 includes a support pad 17, a support screw 18, and a support threaded sleeve 19.

[0035] In this embodiment, the design allows the support component 7 to be height-adjusted as needed to adapt to different working heights and ground conditions. At the same time, the design of the support pad 17 increases the support area, improving the stability and load-bearing capacity of the ladder. The flexibility and adjustability of the support component 7 make the multi-functional articulated ladder more stable and safer when used as a work platform, effectively reducing the safety risks to users.

[0036] Furthermore, limit blocks 20 are provided at the other end of the first support ladder 1, one end of the second connecting ladder, and the other end of the second support ladder 4.

[0037] In this embodiment, the limiting block 20 effectively prevents the ladder from over-expanding during use.

[0038] In this utility model, the multifunctional articulated ladder can be divided into various models according to the number of steps, specifically two-step, three-step, four-step, five-step and six-step. At the same time, the supporting ends of the first leg ladder 1 and the second leg ladder 4 can be either outward V-shaped or H-shaped.

[0039] In this invention, when used as a handcart, the ladder can be unfolded. At this time, the first pin 12 and the second pin 13 are inserted into the corresponding unfolding holes 10. After one end of the second leg ladder 4 deforms, the third pin 14 passes through the folding hole 9 and is inserted into the handrail hole 11, serving as a handrail. Simultaneously, the inner casters 5 facilitate easy movement and pulling of goods. When converted into a support platform, the support screw 18 can be rotated to extend it and adjust to a suitable height, forming a stable working platform for personnel to stand and work on. Furthermore, the ladder components are connected via the folding holes 9, the unfolding holes 10, and the pins, allowing the overall structure to be quickly folded or laid flat as a traditional ladder for easy climbing. This design enables the multi-functional articulated ladder to adapt to different working environments and usage needs, greatly improving its practicality and flexibility.
