Description

Technical Field

[0001] This utility model relates to the technical field of household aluminum ladders, and more particularly to household aluminum ladders that are easy to store. Background Technology

[0002] An aluminum ladder is a type of ladder made primarily of aluminum alloy. Household aluminum ladders are mainly used as climbing tools in the home environment. Household aluminum ladders are easy to store and meet the needs of families for climbing while also being easy to store and saving space.

[0003] Household aluminum ladders are mainly composed of aluminum frames, steps, and other structures. The aluminum frame is the main support structure of the A-frame ladder. When the user unfolds the A-frame ladder and places it on a flat, hard ground, with the angle between the legs at 30°-45°, when climbing, hold the frame with both hands, step on the rungs with both feet, and keep the center of gravity stable. Do not stand on the top rung and avoid overstretching your body when operating. If you need to reach something, you can move the ladder.

[0004] In existing technologies, A-frame ladders not only take up a lot of space and are inconvenient to store after use, but also lack protective measures when climbing, which can easily cause falls and injuries. Therefore, a household aluminum ladder that is easy to store is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a household aluminum ladder that is easy to store, aiming to improve the problems of inconvenient storage and lack of protective measures in the prior art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a conveniently stored household aluminum ladder, including a ladder frame, a folding mechanism inside the ladder frame, and a support mechanism on the outside of the ladder frame. The folding mechanism includes a first fixed column, with the two ends of the four first fixed columns rotatably connected to the inside of the ladder frame. Limit blocks are fixedly connected to the outer sides of the two ends of the first fixed columns near the two sides of the ladder frame. A footboard is fixedly connected to the middle of the outer side of the first fixed column, and an anti-slip groove is provided on the top of the footboard. Fixed plates are fixedly connected to the two sides of the footboard near the limit blocks. Fixed rings are fixedly connected to the far side of the fixed plates. Two fixed columns are fixedly connected inside the two fixed rings. A linkage component is provided on the far side of the two fixed columns.

[0007] As a further description of the above technical solution: the linkage component includes a connecting rod 1, the adjacent sides of the connecting rod 1 are rotatably connected to the far end of the fixed column 2, the middle of the two connecting rods 1 is fixedly connected to a fixed column 3, the far end of the two fixed columns 3 is fixedly connected to a small support rod 1, and the end of the two small support rods 1 away from the fixed column 3 is fixedly connected to a sliding column.

[0008] As a further description of the above technical solution: the support mechanism includes four fixed columns, the outer ends of two fixed columns four that are close to each other are fixedly connected to both ends of the ladder frame, the outer ends of the fixed columns four that are farther from each other are rotatably connected to support frames, and the outer ends of the two support frames that are close to the fixed columns four are fixedly connected to large support rods.

[0009] As a further description of the above technical solution: a medium-sized support rod is fixedly connected to the outer side of one end of the two support frames away from the large support rod, a small support rod is fixedly connected to the outer side of the middle of the two support frames, and a fixed rotating shaft is fixedly connected to the outer side of both ends of the ladder frame, and a protective component is provided on the top of each fixed rotating shaft.

[0010] As a further description of the above technical solution: the protective component includes a shaft, one end of each of the two shafts is rotatably connected to the top of the first fixed rotating shaft, a support armrest is fixedly connected to the outside of the shaft, the top of each shaft is rotatably connected to the second fixed rotating shaft, a button is slidably connected inside the second fixed rotating shaft, and a buckle is fixedly connected to the bottom of each button.

[0011] As a further description of the above technical solution: the buckle is internally slidably connected to a spring, the end of the spring away from the buckle is slidably connected to the top inner side of the axis, the middle of the ladder frame is fixedly connected to an anti-slip handrail, both ends of the ladder frame are fixedly connected to an anti-slip foot one, and the ends of the two support frames away from the fixed column four are fixedly connected to an anti-slip foot two.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, the ladder frame structure and the support frame structure are fixed by the four fixed columns. The opening and closing of the support frame structure and the ladder frame structure allows the medium-sized support rod structure in the support frame structure to be driven by the small support rod structure connected by the sliding column structure. This causes the connecting rod structure at the other end of the small support rod structure to move up and down in a tracked manner. One end of the pedal structure is connected to the connecting rod structure by the two fixed columns. When the connecting rod structure is pushed by the small support rod structure, the other end is fixed to the ladder frame structure, causing the pedal structure to follow the movement and fold on the ladder frame structure. This allows the pedal structure to be folded inside the ladder frame structure, reducing the space occupied and facilitating movement and storage.

[0014] 2. In this utility model, a first fixed pivot structure and a second fixed pivot structure are connected to the outside of the ladder frame structure. With the cooperation of the first fixed pivot structure and the second fixed pivot structure, the shaft structure can rotate between the first fixed pivot structure and the second fixed pivot structure. The shaft structure is connected to the support handrail structure. The locking structure formed by the button structure and the buckle structure inside the second fixed pivot structure is locked between the shaft structure and the second fixed pivot structure by the spring structure. By pressing the button structure, the spring structure is compressed, which makes the buckle structure leave the inside of the second fixed pivot structure, allowing the shaft structure to rotate. This solves the problem of no protection measures. It can not only be used for protection, but also can be folded to reduce the space occupied when stored. Attached Figure Description

[0025] Reference Figure 1 , Figure 2 , Figure 4The support mechanism includes two fixed columns 13, which are used for fixing and supporting. The fixed columns 13 are cylindrical and made of aluminum alloy. The outer ends of the two fixed columns 13 are fixedly connected to both ends of the ladder frame 1. The outer ends of the two fixed columns 13 are rotatably connected to support frames 14, which are used for fixing and supporting. The support frames 14 are square-shaped and made of aluminum alloy. Large support rods 15 are fixedly connected to the outer ends of the two support frames 14 closest to the fixed columns 13. The large support rods 15 are also square-shaped and made of aluminum alloy. A medium-sized support rod 16 is fixedly connected to the outer side of the end of the support frame 14 away from the large support rod 15.

[0026] Reference Figure 2 , Figure 4 , Figure 5 The protective assembly includes a shaft 19 for fixing and rotating. The shaft 19 is cylindrical and made of aluminum alloy. One end of each of the two shafts 19 is rotatably connected to the top of a fixed rotating shaft 18. A support armrest 20 is fixedly connected to the outside of the shaft 19 for support. A fixed rotating shaft 21 is rotatably connected to the top of each shaft 19 for fixing and supporting. The fixed rotating shaft 21 is square-shaped and made of aluminum alloy.

The bottom of each of the two support frames 1 is fixedly connected with a buckle 23 for fixing. The buckle 23 is cylindrical in shape and made of aluminum alloy. A spring 24 is slidably connected inside the buckle 23 to generate elastic force. The end of the spring 24 away from the buckle 23 is slidably connected to the top inner side of the shaft 19. An anti-slip handrail 25 is fixedly connected in the middle of the ladder frame 1 for anti-slip. Anti-slip feet 26 are fixedly connected at both ends of the ladder frame 1 for anti-slip. Anti-slip feet 27 are fixedly connected at the ends of the two support frames 14 away from the fixed column 13 for anti-slip.

[0027] Working principle: When the aluminum ladder is needed, the support frame 14 and the ladder frame 1 are opened and closed through the fixed column 13. When the support frame 14 is pulled outward, it drives the sliding column 12. The sliding column 12 drives the fixed column 10 through the small support rod 11, which in turn causes the connecting rod 9 to rotate around the fixed column 8, thereby unfolding the step 5 and locking it in the appropriate position to form a stable support structure. Users can step on the step 5 to work. The anti-slip groove 4 on the step 5 can prevent the feet from slipping. When storing, the above process is reversed. Pushing the support frame 14 drives the sliding column 12, causing the components to move in the opposite direction, so that the step 5 is folded up and close together towards the ladder frame 1, reducing the space occupied and making it easy to store.

[0028] When in use, the support frame 14 is rotated outward around the fixed column 13. The large support rod 15, medium support rod 16, and small support rod 17 work together to enhance the stability of the support frame 14 and provide support for the ladder frame 1. The support handrails 20 in the fixed pivot 18 and fixed pivot 21 on the ladder frame 1 allow the user to maintain balance. Pressing the button 22 compresses the spring 24 and causes the buckle 23 to disengage from the fixed pivot 21, allowing the angle of the support handrail 20 to be adjusted. After releasing the button 22, the button 22 resets under the action of the spring 24, and the buckle 23 locks again. The anti-slip handrail 25 on the ladder frame 1 is easy to grip. The anti-slip feet 1 and 27 on the ladder frame 1 and the support frame 14 increase the friction with the ground to prevent the ladder frame 1 and the support frame 14 from sliding.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
