Description

Technical Field

[0001] This utility model relates to the field of building auxiliary tools technology, specifically a folding multifunctional ladder. Background Technology

[0002] In construction, interior decoration, and other scenarios, ladders are essential auxiliary tools, and their functionality and safety directly affect work efficiency. Traditional ladders have obvious limitations: on the one hand, they are single-function, and tools such as A-frame ladders, straight ladders, and trestles need to be equipped separately, which is inconvenient to carry and store. Especially when working in multiple scenarios, frequent tool changes increase labor intensity. On the other hand, they lack stability. Traditional ladders lack effective support and protection structures, and are prone to tipping over due to swaying when working at heights. In addition, the limited width of the steps makes it easy for workers to slip, posing a safety hazard. Furthermore, the connection structure of existing folding ladders is mostly snap-on or hinged, which is prone to loosening after long-term use, affecting load-bearing capacity. Moreover, the folded size is still large, making it difficult to meet the transportation needs of narrow spaces. Therefore, we propose a folding multi-functional ladder. Utility Model Content

[0003] The purpose of this utility model is to provide a folding multifunctional ladder.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a folding multifunctional ladder, comprising connecting columns, a connecting component snapped onto the top of the connecting column, and a connecting column snapped onto the inside of the connecting component, and so on. A folding component is snapped onto the top of the connecting column, and a hinge shaft and a hinge column are movably installed inside the folding component. The hinge column is hinged by the hinge shaft inside the folding component. A connecting component is provided at one end of the hinge column, and a connecting column is snapped onto the inside of the connecting component, and so on. A protective net is provided at the top of the connecting column connected to the hinge column, and a footboard is fixedly installed between the two sets of connecting columns.

[0005] As a further embodiment of this utility model: a fixing plate two is fixedly installed on the side of the vertically distributed connecting column, and a side plate two is fixedly installed on the side of the fixing plate two. A second bolt is provided on the surface of the side plate two, and the second bolt extends into the interior of the connecting column.

[0009] As a further embodiment of this utility model: the connecting column and the connecting component are both made of stainless steel, and the outer diameter of the connecting column is equal to the inner diameter of the connecting component.

[0010] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0011] 1. This utility model, through the combined design of connecting components and folding parts, enables flexible assembly and form switching of the ladder: multiple sets of connecting columns are spliced ​​together by connecting components to form a straight ladder; by using the hinge axis of the folding parts to link with the hinge columns, it can be folded into a trestle or an A-frame ladder to meet the needs of different scenarios such as high-altitude climbing and low-altitude work, realizing multi-form conversion and adapting to diverse scenarios.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0020] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] Please see the appendix Figure 1 - Appendix Figure 4 This utility model provides a folding multifunctional ladder, including a connecting column 1, a connecting component 2 snapped onto the top of the connecting column 1, and a connecting column 1 snapped onto the inside of the connecting component 2, and so on. A folding component 3 is snapped onto the top of the connecting column 1. A hinge shaft 6 is provided inside the folding component 3 and a hinge column 5 is movably installed. The hinge column 5 is hinged inside the folding component 3 by the hinge shaft 6. A connecting component 2 is provided at one end of the hinge column 5, and a connecting column 1 is snapped onto the inside of the connecting component 2, and so on. A protective net 17 is provided on the top of the connecting column 1 connected to the hinge column 5. A footboard 4 is fixedly installed between the two sets of connecting columns 1.

[0022] The above solution allows for flexible assembly and form switching of the ladder through the combined design of connecting component 2 and folding component 3: multiple connecting columns 1 are spliced ​​together by connecting component 2 to form a straight ladder; by using the hinge shaft 6 of folding component 3 to link with the hinge column 5, it can be folded into a treadmill or A-frame ladder to meet the needs of different scenarios such as high-altitude climbing and low-altitude work, achieving multi-form conversion and adapting to diverse scenarios. At the same time, the snap-fit ​​structure between connecting column 1 and connecting component 2 facilitates quick disassembly, easy folding and storage, and saves space and transportation costs.

[0023] like Figure 3 As shown, a fixing plate 2 10 is fixedly installed on the side of the vertically distributed connecting column 1, and a side plate 2 11 is fixedly installed on the side of the fixing plate 2 10. A second bolt 12 is provided on the surface of the side plate 2 11 and extends into the interior of the connecting column 1. A fixing plate 1 7 is fixedly installed at the bottom of the horizontally distributed connecting column 1. A side plate 1 8 is fixedly installed on the side of the fixing plate 1 7 and a first bolt 9 is provided on the surface of the side plate 1 8 and extends into the interior of the connecting column 1. A connecting plate 13 is fixedly installed between the fixing plate 1 7 and the fixing plate 2 10.

[0024] The above solution is adopted: a stable triangular support system is formed by fixing plate 7, fixing plate 10 and connecting plate 13. The geometric stability of the triangle is used to distribute the force on the ladder, thereby improving the overall anti-tilting ability. The structure can still remain stable on uneven ground or when subjected to lateral force, which solves the problem of traditional ladders swaying when working at heights.

[0025] like Figure 3 As shown, a bracket 14 is provided on the side of the vertically distributed pedal 4. Anti-tipping columns 15 are movably installed at both ends of the bracket 14. A third bolt 16 is provided on the side of the bracket 14, and the third bolt 16 extends into the interior of the pedal 4.

[0026] The above solution involves fixing the bracket 14 to the pedal 4 with the third bolt 16, and adjusting the height of the anti-tipping column 15 from the ground to support the device and improve safety.

[0027] like Figure 1 As shown, a widened step board can be added to the surface of pedal 4;

[0028] The above solution involves adding a widened step plate to the surface of pedal 4, thereby increasing the contact area between the worker and the device and thus improving the worker's safety.

[0029] like Figure 1 As shown, a double column can be added to the surface of the connecting column 1, and a U-shaped foot 18 is provided at the bottom of the connecting column 1;

[0030] The above solution is adopted: by adding double columns to the surface of the connecting column 1, the stability of the A-frame ladder is improved when it is transformed into an A-frame ladder. A U-shaped foot 18 is provided at the bottom of the connecting column 1, so that the height of the U-shaped foot 18 can be adjusted to keep the ladder level when the device is uneven or has pits.

[0031] like Figure 1 As shown, both the connecting column 1 and the connecting component 2 are made of stainless steel, and the outer diameter of the connecting column 1 is equal to the inner diameter of the connecting component 2.

[0032] The above solution is adopted: by making both the connecting column 1 and the connecting component 2 from stainless steel, which has high strength and good rust resistance, the outer diameter of the connecting column 1 and the inner diameter of the connecting component 2 are set to be equal, thereby improving the connection between the connecting column 1 and the connecting component 2.

[0033] This device can be assembled into A-frame ladders, straight ladders, trestles, tree ladders, and stair treads in different ways, making it highly practical.

[0034] Working principle:

[0035] Workers select the number of connecting columns 1 according to the work requirements, and then splice them layer by layer through connecting components 2: the top of the lower connecting column 1 is inserted into the bottom groove of the connecting component 2, and then the bottom of the upper connecting column 1 is inserted into the top groove of the connecting component 2. By using the precise matching of the outer diameter of the connecting column 1 and the inner diameter of the connecting component 2, it is ensured that there is no looseness after splicing. The two sets of parallel connecting columns 1 are fixed to the steps 4 with bolts to form the basic frame of the ladder. The surface of the steps 4 can be widened and the stepping area can be increased as needed.

[0036] Straight Ladder Form: Multiple sets of connecting columns 1 are longitudinally spliced ​​together via connecting components 2. No folding parts 3 need to be installed at the top, directly forming a straight ladder for high-altitude climbing, suitable for wall decoration, lighting installation, and other scenarios; Stool Form: Folding parts 3 are snapped onto the top of two sets of parallel connecting columns 1. The hinged column 5 is unfolded to a horizontal state via the hinge shaft 6. The end of the hinged column 5 is connected to the short connecting column 1 via the connecting components 2, forming an "I"-shaped stool structure, suitable for low-altitude work such as indoor ceiling installation and painting; A-frame Ladder Form: Two sets of connecting columns 1 are folded inward via the hinge shaft 6 of the folding parts 3, so that the hinged column 5 and the main connecting column 1 form an angle of 30 to 60 degrees. It stands upright on the ground using the principle of triangular stability. At this time, double columns can be added to the surface of the connecting column 1 to enhance lateral load-bearing capacity, suitable for outdoor high-altitude work;

[0037] Triangular support reinforcement: For A-frame ladders or trestles, the second fixing plate 10 is fixed to the side of the vertical connecting column 1 by the second bolt 12, and the first fixing plate 7 is fixed to the bottom of the horizontal connecting column 1 by the first bolt 9. The connecting plate 13 between the first fixing plate 7 and the second fixing plate 10 forms a triangular structure, which distributes the force on the ladder and increases the anti-tilting ability by 80%. Anti-tipping auxiliary support: On the side of the vertically distributed steps 4, the bracket 14 is fixed by the third bolt 16. The height of the anti-tipping columns 15 at both ends of the bracket 14 is adjusted so that the bottom of the column is in close contact with the ground, further suppressing the swaying of the ladder. This is especially suitable for uneven outdoor ground.

[0038] After the form is assembled, the staff can step on the step plate 4 to work: the top protective net 17 surrounds the work area to prevent tools from falling or people from slipping; the widened step plate increases the friction with the sole of the shoe to reduce the risk of slipping. After the work is completed, the folding part 3 is reversed, the connecting component 2 is disassembled, and the connecting column 1, step plate 4 and other parts are disassembled and stored. After folding, the volume is reduced to one-third of the unfolded state, which is convenient for transportation and storage.
