Description

Technical Field

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

[0002] Vehicle-mounted ladders have been widely used in special-purpose vehicles. They are usually either mobile or fixed. Mobile ladders are mostly fixed inside the vehicle or on the rear panel of the vehicle body. They need to be removed and placed in a designated location when working. They need to be moved and installed every time, which is cumbersome and inconvenient to use. Fixed ladders are mainly installed at the rear or side of the vehicle body. Although this structure is simple, it takes up a lot of space, and the ladder is perpendicular to the ground, making it dangerous to climb up and down.

[0003] Therefore, a flip-up ladder device is needed to solve the above-mentioned technical problems. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a flipping ladder device.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A flip-up ladder device includes a ladder body, a first rotating folding part, and a second rotating folding part. The first rotating folding part and the second rotating folding part are respectively installed on the upper and lower parts of the ladder body, and a locking buckle is installed between the second rotating folding part and the ladder body.

[0006] The first rotating folding part includes a first fixed plate, a first rotating rod, and a first bracket. The first bracket is fixed on the first fixed plate, one end of the first rotating rod is rotatably connected to the first bracket, and the other end of the first rotating rod is rotatably connected to the ladder body.

[0007] The second rotating folding part includes a second fixed plate, a second rotating rod, and a second bracket. The second bracket is fixed on the second fixed plate. One end of the second rotating rod is rotatably connected to the second bracket, and the other end of the second rotating rod is rotatably connected to the ladder body. The length of the second rotating rod is greater than the length of the first rotating rod.

[0008] Preferably, in the above-described flipping ladder device, a bottom connecting frame is fixed on the second fixed plate, a top connecting frame is fixed on the second rotating rod, and an elastic support rod is installed between the bottom connecting frame and the top connecting frame.

[0009] Preferably, in the above-described flip ladder device, the bottom of both the first support and the second support are equipped with limiting components.

[0010] Preferably, in the above-mentioned flipping ladder device, the limiting member is a limiting baffle, and the bottom of the first bracket and the second bracket are both provided with through grooves, and the limiting baffle is inserted into the through groove.

[0011] Preferably, in the above-mentioned flipping ladder device, two sets of connecting members are fixed on the ladder body, and the first rotating rod and the second rotating rod are rotatably connected to the connecting members respectively.

[0012] Preferably, in the above-described flipping ladder device, a plurality of pads are fixed on the ladder body, and the pads are located between the first rotating rod and the ladder body and between the second rotating rod and the ladder body.

[0013] Preferably, in the above-mentioned flipping ladder device, both the first fixing plate and the second fixing plate are provided with threaded holes.

[0014] The beneficial effects of this utility model are: the extension depth of the ladder in the retracted and folded state is shortened, occupying less space and making it convenient to install on vehicles; in the unfolded working state, the steps are horizontally and longitudinally distributed, which meets ergonomic requirements and increases safety; this device can help operators save effort during the unfolding and folding process through elastic support rods; the bottom of the ladder maintains a certain distance from the ground, and the rigidity and strength of the ladder frame itself meet the load-bearing capacity, which is not affected by uneven terrain, and has higher reliability and safety.

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] like Figures 1-4 As shown, a flip-up ladder device includes a ladder body 1, a first rotating folding part 2, and a second rotating folding part 3, which are respectively installed at the upper and lower parts of the ladder body 1. Two sets of connecting parts 6 are fixed on the ladder body 1, and the first rotating folding part 2 and the second rotating folding part 3 are respectively connected to the connecting parts 6.

[0023] The first rotating folding part 2 includes a first fixed plate 21, a first rotating rod 22, and a first bracket 23. The first bracket 23 is fixed on the first fixed plate 21. One end of the first rotating rod 22 is rotatably connected to the first bracket 23 via a first rotating shaft 24, and the other end of the first rotating rod 22 is rotatably connected to a set of connecting parts 6 on the upper part of the ladder body 1.

[0024] The second rotating folding part 3 includes a second fixed plate 31, a second rotating rod 32, and a second bracket 33. The second bracket 33 is fixed to the second fixed plate 31. One end of the second rotating rod 32 is rotatably connected to the second bracket 33 via a second rotating shaft 34, and the other end of the second rotating rod 32 is rotatably connected to a set of connecting parts 6 at the lower part of the ladder body 1. A latch 5 is installed between the second rotating folding part 3 and the ladder body 1. Specifically, the latch 5 is installed between the second bracket 33 and the ladder body 1.

[0025] Both the first fixing plate 21 and the second fixing plate 31 are fixed to the rear of the vehicle. Both the first fixing plate 21 and the second fixing plate 31 are provided with threaded holes to facilitate fixed connection with the rear of the vehicle.

[0026] The length of the second rotating rod 32 is greater than the length of the first rotating rod 22. For example... Figure 4 As shown, the dashed line represents the position of the ladder after it is extended, and the solid line represents the position of the ladder after it is folded. In the folded state, the ladder body 1 is parallel to the rear of the vehicle, and the first rotating rod 22 and the second rotating rod 32 are nearly parallel to the two sides of the ladder body 1, with an included angle of less than 10°; after the ladder is extended, the ladder body 1 is tilted.

[0027] A bottom connecting frame 35 is fixed to the second fixed plate 31, and a top connecting frame 36 is fixed to the second rotating rod 32. An elastic support rod 37, which is a gas spring support rod, is installed between the bottom connecting frame 35 and the top connecting frame 36. When the ladder is extended, the elastic support rod 37 provides assistance, making it easier and less strenuous for people to unfold the ladder. In the extended state, the bottom of the ladder body 1 still maintains a certain distance from the ground, unaffected by the terrain.

[0028] Both the first support 23 and the second support 33 have limiting components installed at their bottoms. These limiting components are limiting baffles 26, and both the first support 23 and the second support 33 have through grooves 25 at their bottoms, with the limiting baffles 26 fitting into the through grooves 25. Multiple pads 4 are fixed to the ladder body 1, located between the first rotating rod 22 and the ladder body 1, and between the second rotating rod 32 and the ladder body 1. When the ladder is extended, the limiting baffles 26 limit the movement of the first rotating rod 22 and the second rotating rod 32; when the ladder is folded up, the pads 4 buffer and limit the movement of the first rotating rod 22 and the second rotating rod 32.

[0029] In use, unlock latch 5 to release the restriction of the ladder body 1 on the second support 33, pull the ladder body 1, the first rotating rod 22 and the second rotating rod 32 will rotate, the ladder will unfold and maintain a certain angle, the upper and lower steps are roughly horizontally and longitudinally distributed, which meets the ergonomic requirements when climbing. After use, push the ladder body 1 in the opposite direction, the first rotating rod 22 and the second rotating rod 32 will rotate in the opposite direction, fold it and lock latch 5, so that the ladder is in a stable folded state.
