Description

Technical Field

[0001] The utility model relates to the technical field of assembled steel ladders, in particular to an assembled adjustable steel ladder. Background Technique

[0002] A ladder is a daily necessity. This tool consists of two long and thick poles as the sides, with crossbars suitable for climbing in the middle, and is used for climbing heights. Ladders are divided into lifting single ladders and lifting A-frame ladders. With the development of the times, ordinary steel ladders with fixed dimensions have gradually been phased out. In order to save storage space, generally, steel ladders with adjustable heights are used for different scenarios.

[0003] For traditional steel ladders with adjustable heights, when adjusting their heights, pulleys and ropes are generally used in combination. However, the overall length of this kind of ladder is also relatively long. When carrying it, due to the relatively high height of the ladder itself, it is not particularly convenient to carry.

[0004] Therefore, we propose an assembled adjustable steel ladder. Content of the Utility Model

[0005] The purpose of the utility model is to provide an assembled adjustable steel ladder to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An assembled adjustable steel ladder, including a storage box and a storage component. The storage component is placed on the ground and is used for facilitating the collection, movement, and use of various components of the steel ladder. There is also an assembly component, which is installed on the upper part of the storage box and is used for quickly assembling each individual steel ladder component.

[0007] Preferably, the storage component includes a storage box. Four self-locking wheels distributed in a rectangle are fixedly connected to the bottom surface of the storage box. Two fixing plates are fixedly connected to the right side of the upper surface of the storage box. A round rod is fixedly connected between the two mutually approaching surfaces of the two fixing plates. A rotating block is rotatably connected to the outer surface of the round rod. An inclined plate is fixedly connected to the right side of the upper surface of the storage box.

[0008] Preferably, the self-locking wheels are universal wheels with a self-locking structure.

[0009] Preferably, the inclined plate is inclined at a certain angle.

[0010] Preferably, a traction handle is fixedly connected to the top end of the inclined plate.

[0011] Preferably, the assembly component includes a steel ladder member. Empty grooves are formed on both the left and right sides of the upper surface of the steel ladder member. A set of guiding grooves are formed on both the left and right sides of the steel ladder member. Connecting plates are fixedly connected to both the left and right sides of the steel ladder member. Second mounting plates are fixedly connected to the ends of the two connecting plates away from each other. First mounting plates are clamped to the outer surfaces of the two connecting plates. Two elastic steel plates are fixedly installed between the surfaces of each first mounting plate close to the second mounting plate. Blocks are fixedly connected to the surfaces of the two first mounting plates close to the steel ladder member. The position of each block is inserted into the position of the corresponding guiding groove. Two inserting plates are fixedly connected to the bottom surface of the steel ladder member. Card slots are formed on the right side surfaces of the two inserting plates.

[0012] Preferably, the size and thickness of the inserting plate are adapted to the size and thickness of the empty groove, and the size of the card slot is adapted to the size and position of the block.

[0013] Preferably, the bottom surface of the lowermost steel ladder member is fixedly installed on the upper part of the outer surface of the rotating block.

[0014] The utility model has at least the following beneficial effects:

[0015] 1. When the whole device needs to be moved and carried, first place each individual steel ladder member inside the storage box, and then pull the traction handle. Through the self-locking wheels provided, the whole device can be moved. When the whole device moves to a suitable position, at this time, through the self-locking function of the self-locking wheels, the whole device will no longer move. At this time, it is necessary to assemble each steel ladder member. After assembling to a suitable height, the whole of multiple steel ladder members can be tilted so that the steel ladder member is tilted onto the surface of the inclined plate for workers to climb.

[0016] By providing the storage component, the whole device can be made to be easily movable, and the whole device can occupy less space when being stored.

[0017] 2. When assembling the steel ladder components, only need to insert the two plug plates on the bottom surface of the upper steel ladder component into the two empty slots opened on the upper surface of the lower steel ladder component. When the plug plates are inserted into the inside of the empty slots, the bottom ends of the plug plates will first contact the inclined surfaces of the clamping blocks. At this time, the clamping blocks can be moved in the direction away from each other. When the plug plates continue to be inserted, the card slots will be aligned with the clamping blocks. At this time, under the action of the elastic force of the elastic steel plates, the clamping blocks can be snapped into the inside of the card slots. By bravely setting the connecting plate to guide the first mounting plate, the clamping blocks can move more stably when moving. After the clamping blocks are inserted into the inside of the card slots, at this time, the bottom surface of the upper steel ladder component will contact the upper surface of the lower steel ladder component, making the plug plates unable to continue to descend. When the length of the steel ladder needs to be changed, only need to repeat the above operations. When the steel ladder needs to be disassembled, only need to pull the second mounting plate to extract the clamping blocks from the inside of the card slots, and then the steel ladder components can be disassembled.

[0018] By setting the assembling component, it can achieve the effect of facilitating the splicing or disassembly of each steel ladder component. Further, the overall device can save more space after disassembly, and make the overall device easier to move and carry. BRIEF DESCRIPTION OF THE DRAWINGS

An inclined plate 5 is fixedly connected to the right side of the upper surface of the storage box 3.

[0028] The self-locking wheel 4 is a universal wheel with a self-locking structure.

[0029] The inclined plate 5 is inclined at a certain angle, so that the steel ladder parts 10 can be inclined on the surface of the inclined plate 5 after being assembled, which can make it easier to climb the steel ladder.

[0030] A traction handle 6 is fixedly connected to the top end of the inclined plate 5, which can facilitate the overall traction and pulling of the device.

[0031] When the whole device needs to be moved and transported, first place each individual steel ladder part 10 inside the storage box 3, and then pull the traction handle 6. Through the set self-locking wheels 4, the whole device can be moved. When the whole device moves to a suitable position, at this time, through the self-locking function of the self-locking wheels 4, the whole device will no longer move. At this time, it is necessary to assemble each steel ladder part 10. After assembling to a suitable height, the whole of multiple steel ladder parts 10 can be inclined, so that the steel ladder parts 10 are inclined onto the surface of the inclined plate 5 for workers to climb easily.

[0032] By setting the storage component 1, the whole device can be made to be easily movable, and the whole device can occupy less space when being stored.

[0033] Embodiment 2. The root assembly component 2 includes a steel ladder member 10. Empty slots 11 are provided on both the left and right sides of the upper surface of the steel ladder member 10. A set of guiding slots 14 are provided on both the left and right sides of the steel ladder member 10. Connecting plates 17 are fixedly connected to both the left and right sides of the steel ladder member 10. Second mounting plates 18 are fixedly connected to the ends of the two connecting plates 17 away from each other. First mounting plates 16 are clamped on the outer surfaces of the two connecting plates 17. Two elastic steel plates 19 are fixedly installed between the surfaces of each first mounting plate 16 close to the second mounting plate 18. Clamping blocks 15 are fixedly connected to the surfaces of the two first mounting plates 16 close to the steel ladder member 10. The position of each clamping block 15 is inserted into the position of the corresponding guiding slot 14. Two inserting plates 12 are fixedly connected to the bottom surface of the steel ladder member 10. Card slots 13 are provided on the right side surfaces of the two inserting plates 12.

[0034] The size and thickness of the inserting plate 12 are adapted to the size and thickness of the empty slot 11.

When the inserting plate 12 is continuously inserted, the card slot 13 will be aligned with the clamping block 15. At this time, under the action of the elastic force of the elastic steel plate 19, the clamping block 15 can be clamped into the interior of the card slot 13. By setting the guiding function of the connecting plate 17 on the first mounting plate 16, the clamping block 15 can move more stably. After the clamping block 15 is inserted into the interior of the card slot 13, at this time, the bottom surface of the upper steel ladder member 10 will contact the upper surface of the lower steel ladder member 10, making the inserting plate 12 unable to continue to descend. When the length of the steel ladder needs to be changed, only need to repeat the above operation. When the steel ladder needs to be disassembled, only need to pull the second mounting plate 18 to extract the clamping block 15 from the interior of the card slot 13, and then each steel ladder member 10 can be disassembled.

[0037] By setting the assembly component 2, the effect of facilitating the splicing or disassembly of each steel ladder member 10 can be achieved. Further, the whole device can save more space after disassembly, and it is easier to move and carry the whole device.
