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

[0002] In engineering construction, ladders are often used to assist in completing tasks at heights, such as indoor ceiling construction and construction of the ceiling in corridors. For example, the utility model patent with authorization announcement number CN201943558U, entitled "Anti-slip Folding Ladder", includes two ladders placed opposite each other. Each ladder has two ladder columns connected by rungs. The tops of the two ladders are connected by foldable steps, and the middle of the two ladders are connected by a foldable connecting plate. Suction cups are provided at the bottom of each ladder column. The suction cups at the bottom of this anti-slip folding ladder not only solve the problem of folding ladders easily sliding on the bottom surface and causing danger, but also enhance the insulation performance of the folding ladder.

[0003] However, when workers use the aforementioned folding ladder, the area available for work on the ceiling is too small. When workers need to work on other areas of the ceiling, they need to get off the folding ladder and move it. This frequent climbing and moving of the ladder results in low construction efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a folding ladder to solve the technical problem that when the construction area at a high place is large, workers need to frequently climb up and down the ladder and move the ladder, resulting in low construction efficiency.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a folding ladder, including a ladder, a flat plate, support rods, and a bamboo frame. The ladders are arranged in pairs, and the bottom surface of the flat plate is hinged to one end of the two ladders, with the two ladders arranged opposite each other. Several support rods are provided, and the support rods are hinged to the ladders. The support rods are used to support the two ladders and make the other end of the two ladders suspended in the air. The bamboo frame is used to be placed horizontally at the end of the two ladders away from the flat plate.

[0007] In some embodiments, the ladder includes a pair of vertical bars and a plurality of horizontal bars, the two vertical bars being arranged opposite each other, and the horizontal bars being arranged at equal intervals and fixedly connected between the two vertical bars.

[0008] In some embodiments, a first hinge frame is fixedly connected to one end of the vertical rod, and a second hinge frame is fixedly connected to the bottom surface of the plate, wherein the first hinge frame and the second hinge frame are hinged together.

[0009] In some embodiments, one end of the vertical rod is provided with a first plane, and the first plane is adjacent to the first hinge frame.

[0010] In some embodiments, the other end of the vertical rod is provided with a second plane, and the first plane and the second plane are parallel to each other.

[0011] In some embodiments, the second plane is fitted with an anti-slip pad.

[0012] In some embodiments, one end of the support rod is hinged to the side wall of the vertical rod, and the other end of the support rod is provided with a third plane.

[0013] In some embodiments, the third plane is fitted with an anti-slip pad.

[0014] In some embodiments, a limiting protrusion is fixedly connected to the side wall of the vertical rod, and the limiting protrusion is disposed adjacent to the support rod.

[0015] In some embodiments, the top surface of the flat plate is provided with anti-slip texture.

[0016] Compared with the prior art, the folding ladder provided by this utility model has a structure that does not tip over when the ladder is upside down by setting up support rods.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0022] To address the technical problem of low construction efficiency caused by workers frequently climbing and moving ladders when working at heights over large areas, this invention provides a folding ladder that reduces the frequency of workers climbing and moving ladders, thereby improving construction efficiency.

[0023] It should be noted that the folding ladder described in this utility model is used in, but not limited to, construction engineering, etc. For ease of explanation, this utility model only uses the application of a folding ladder in construction engineering as an example for explanation. The principle of applying a folding ladder to other types of equipment is essentially the same as the principle of applying it to construction engineering, and will not be described in detail here.

[0024] Please see Figure 1 - Figure 3 ,in Figure 1 This is a schematic diagram of the structure of a folding ladder in one embodiment of the present invention. The folding ladder includes a ladder 1, a flat plate 2, support rods 3 and a bamboo frame board 4. The ladders 1 are arranged in pairs. The bottom surface of the flat plate 2 is hinged to one end of the two ladders 1 and the two ladders 1 are arranged opposite each other. There are several support rods 3. The support rods 3 are hinged to the ladders 1 and are used to support the two ladders 1 and make the other end of the two ladders 1 suspended. The bamboo frame board 4 is used to be placed horizontally at the end of the two ladders 1 away from the flat plate 2.

[0025] In this embodiment, the support rod 3 forms a structure that prevents the ladder 1 from tipping over when it is upside down. The bamboo frame 4 is placed horizontally on top of the upside-down ladder 1, allowing workers to move on the bamboo frame 4. This increases the workers' working area, reduces the frequency of workers climbing up and down the ladder 1 and moving the ladder 1, and effectively improves construction efficiency.

[0026] It should be noted that the device has two states: a conventional use mode and an inverted use mode. When construction is required on a small area at a height, the flat plate 2 is at the top, which is the conventional use mode. When construction is required on a large area at a height, the bamboo frame board 4 is at the top, which is the inverted use mode.

[0027] In one embodiment, the ladder 1 includes a pair of vertical bars 11 and a plurality of horizontal bars 12. The two vertical bars 11 are arranged opposite each other, and the horizontal bars 12 are arranged at equal intervals and fixedly connected between the two vertical bars 11.

[0028] In this embodiment, both the vertical rod 11 and the horizontal rod 12 are made of stainless steel tubing and have a hollow structure, which effectively reduces the weight of the entire device and makes it easy to transport.

[0029] In one embodiment, a first hinge frame 111 is fixedly connected to one end of the vertical rod 11, and a second hinge frame 21 is fixedly connected to the bottom surface of the plate 2. The first hinge frame 111 and the second hinge frame 21 are hinged together.

[0030] In this embodiment, the first hinge frame 111 is hinged to the second hinge frame 21, so that the device has a folding and storage function, reducing the space occupied and making it easy to carry.

[0031] In one embodiment, one end of the vertical rod 11 is provided with a first plane 112, and the first plane 112 is adjacent to the first hinge frame 111.

[0032] In this embodiment, when the first plane 112 overlaps and abuts with the bottom surface of the plate 2, the ladder 1 can no longer rotate through the first hinge frame 111 and the second hinge frame 21, thereby fixing the ladder 1 and making the ladder 1 stable, which is convenient for workers to climb.

[0033] In one embodiment, the other end of the vertical rod 11 is provided with a second plane 113, and the first plane 112 and the second plane 113 are parallel to each other.

[0034] In this embodiment, the second plane 113 overlaps and abuts with the ground, and together with the first plane 112 and the flat plate 2 overlap and abut, they are used to restrict the ladder 1, so that the ladder 1 cannot rotate through the first hinge frame 111 and the second hinge frame 21, so that the ladder 1 is in a stable state and it is convenient for workers to climb.

[0035] In one embodiment, the second plane 113 is fitted with an anti-slip pad 13.

[0036] In this embodiment, the anti-slip pad 13 is used to increase the friction between the second plane 113 and the ground, so as to prevent the ladder 1 from slipping during normal use.

[0037] In one embodiment, one end of the support rod 3 is hinged to the side wall of the vertical rod 11, and the other end of the support rod 3 is provided with a third plane 31.

[0038] In this embodiment, the function of the third plane 31 is to facilitate the end of the support rod 3 to abut against the ground, thereby forming effective support and maintaining the stability of the ladder 1 when used upside down.

[0039] In one embodiment, the third plane 31 is fitted with an anti-slip pad 32.

[0040] In this embodiment, the anti-slip pad 32 is used to increase the friction between the third plane 31 and the ground, so as to prevent the ladder 1 from slipping when used upside down.

[0041] In one embodiment, a limiting protrusion 114 is fixedly connected to the side wall of the vertical rod 11, and the limiting protrusion 114 is arranged adjacent to the support rod 3.

[0042] In this embodiment, the function of the limiting protrusion 114 is to prevent the support rod 3 from continuing to rotate. After the support rod 3 supports the inverted ladder 1, the support rod 3 cannot continue to rotate under the action of the limiting protrusion 114, thus maintaining the stability of the ladder 1 when it is used inverted, and making it easier for workers to climb.

[0043] In one embodiment, the top surface of the flat plate 2 is provided with anti-slip texture 22.

[0044] In this embodiment, during normal use, it prevents workers from slipping on the flat plate 2. When used upside down, it increases the friction between the flat plate 2 and the ground, improves the stability of the ladder 1 in the upside-down state, and makes it easier for workers to climb.

[0045] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail below:

[0046] When constructing in a small area at a height, this device is used in a conventional manner. The plate 2 is located at the top. Using the first hinge frame 111 and the second hinge frame 21, the two ladders 1 are flipped so that the first plane 112 is parallel to and abuts against the plate 2, and the second plane 113 is parallel to and abuts against the ground. Workers can use the horizontal bar 12 to climb to the height for construction, up to the height of the plate 2.

[0047] When constructing on a large area at a height, the device is used upside down, with the flat plate 2 at the bottom and abutting against the ground. Using the first hinge frame 111 and the second hinge frame 21, the two ladders 1 are flipped so that the first plane 112 is parallel to and abuts against the flat plate 2. The support rods 3 are flipped so that the third plane 31 is parallel to and abuts against the ground. The bamboo frame board 4 is placed on the highest horizontal bar 12. Workers can climb the horizontal bar 12 to the height of the bamboo frame board 4 to carry out construction. By setting up the bamboo frame board 4, the range of work that workers can carry out is increased, the frequency of workers climbing up and down the ladders 1 and moving the ladders 1 is reduced, and thus the construction efficiency is improved.

[0048] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
