Description

Technical Field

[0001] This utility model relates to the field of home decoration and renovation, and in particular to steel pipe ladders with handrails for home use. Background Technology

[0002] In modern residential architecture, with increasingly scarce land resources and diverse apartment layouts, staircases have become an essential component for safe and convenient movement between floors. Steel pipe staircases, with their high structural strength and ability to withstand weight and impact, are suitable for frequently used home environments and have become an ideal choice for connecting upper and lower floors. In smaller homes, efficient space utilization is crucial. The relatively compact structure of steel pipe staircases allows for flexible design based on interior space layout.

[0003] A household steel pipe ladder is a facility used indoors or outdoors to connect different floors or areas at different heights. It mainly consists of two parts: a steel pipe frame and handrails. The steel pipe frame is the supporting structure of the entire ladder, including the ladder beams (usually two main steel pipes) and the treads (generally metal or wooden plates connected to the ladder beams by welding, bolts, etc.). The handrails are installed on both sides of the ladder beams for people to hold onto when going up and down the stairs, providing additional safety. The handrails are also usually made of steel pipes.

[0004] During use, noise can be generated when a person's hand or body comes into contact with or rubs against the steel pipe handrail, especially at night or in environments where quiet is required. This noise can affect the rest of family members.

[0005] The shape and hardness of steel pipes determine that their handrails are not as comfortable as those made of some soft materials. Relying on or gripping them for a long time can cause fatigue and discomfort. For example, this discomfort will be more obvious when you need to hold the handrail for a long time when going up or down stairs. Therefore, a steel pipe ladder for home use is proposed to solve the above problems. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a steel pipe ladder with handrails for home use, aiming to improve the problem of handrail storage in the prior art.

[0033] Reference Figure 1 , Figure 2 This utility model provides an embodiment of a household handrail steel pipe ladder, including a folding mechanism 1 for folding and storage to save space. A storage handrail 2 is fixedly connected to the outside of the folding mechanism 1 for storing the handrail, which can be stored as needed. A limiting mechanism 3 is fixedly connected to the outside of the storage handrail 2 to fix its position. The storage handrail 2 includes a second fixed column 201 for supporting the mechanism and providing support force. A second fixed block 202 is fixedly connected to the outside of the second fixed column 201 to provide support force and fix its position. A connecting rod 206 is rotatably connected to the outside of the second fixed column 201, allowing it to rotate and regulating its movement position. Two fixing blocks 202 are fixedly connected to the outer end of the connecting rod 206 near the fixed column 201 to fix the position of the column 201 and to fix it to the support frame 101. Fixing its position ensures the normal operation of the equipment. Two rotating rods 203 are fixedly connected to the outer end of the connecting rod 206 away from the fixed column 201 to fix the connecting rod 206 to the movable handrail 205 to fix its position. The outer end of the connecting rod 206 away from the fixed column 201 is rotatably connected to the outside of the fixed column 3 204 and moves outside of it to provide a support shaft for its movement. The outside of the rotating rods 203 is connected to the movable handrail 205 and fixed to the movable handrail 205 to move together with it.

[0034] ReferenceFigure 1 , Figure 3 The folding mechanism 1 includes a support frame 101. A fixing ring 102 is fixedly connected to the outside of the support frame 101 for connecting other mechanisms to provide support. A support frame 2 103 is fixedly connected inside the fixing ring 102 to provide support for the support frame 101. A fixing column 104 is fixedly connected to the outside of the support frame 2 103 to provide support for the ladder 106. A linkage column 105 is fixedly connected inside the fixing column 104 to connect the fixing columns 104 connected to the three ladder 106 and drive them to move together. A connecting column 108 is fixedly connected to the outside of the linkage column 105 to connect the linkage column 105 and the support frame 2 103. When the support frame 2 103 is folded inward, it drives the linkage column 105 to move upward, thereby achieving the effect of moving together. The connecting column 108 is fixedly connected to the outside of the support frame 2 103 and connects it to the linkage column 105.

[0035] The second support frame 103 is internally fixedly connected to a second connecting column 110, which provides greater support and increases its stability. The bottom of the second support frame 103 is threadedly connected to a caster wheel 111, which can be disassembled and installed as needed. When it needs to be moved, it can be installed to facilitate movement. The first support frame 101 is internally connected to three third connecting columns 112, which fix the three ladder plates 106 in position. The bottom of the third connecting column 112 of the first support frame 101 is threadedly connected to an anti-slip pad 109. The caster wheel 111 can be disassembled during operation, and the anti-slip pad 109 can be installed to achieve an anti-slip effect. The third connecting column 112 is externally fixedly connected to a ladder plate 106 to fix its position. The ladder plate 106 is externally fixedly connected to an anti-slip block 107 for anti-slip purposes and to increase its friction. The first support frame 101 is externally fixedly connected to a second fixing block 202 to fix its position. The first support frame 101 is externally fixedly connected to a third fixing block 301 to fix its position and ensure the normal operation of the mechanism.

[0036] Reference Figure 1 , Figure 4The limiting mechanism 3 includes a fixing block 301, which is used to fix the mechanism and provide support. A fixing column 4 303 is fixedly connected inside the fixing block 301, providing support for it and the mechanism to which it is connected. A rotating rod 2 302 is rotatably connected to the outside of the fixing column 4 303, allowing it to rotate. A fixing block 5 308 is fixedly connected to the outside of the rotating rod 2 302 for fixing. A fixing block 4 307 is fixedly connected to the outside of the fixing block 5 308, working together to fix it. The fixed block 301 has a spring 304 internally slidingly connected for support. The spring 304 is externally fixedly connected to a fixed post 306, which moves together with the spring to achieve the effect of moving together. The fixed post 306 is externally slidingly connected to the inside of the limiting block 305 to regulate its position. The end of the rotating rod 2 302 away from the fixed post 4 303 is rotatably connected to the outside of the fixed post 6 310 to provide support. The two ends of the fixed post 6 310 are fixedly connected to fixed blocks 6 309 to fix its position and provide support.

[0037] Working principle: When climbing stairs, the movable handrail 205 in the limiting mechanism 3 can be pulled upwards, thereby driving the movement of the connecting rod 206 fixed on the support frame 101 and the fixed block 202 in the storage handrail 2. At the same time, the fixed block 202 fixes the fixed column 201 in position. Since the connecting rod 206 moves on the fixed column 201, the movement of the connecting rod 206 is achieved. The end of the connecting rod 206 away from the support frame 101 is fixed to the rotating rod 2 by the fixed column 3 204. 03 and the rotating rod 203 is fixed on the movable handrail 205. Then the end of the connecting rod 206 away from the support frame 101 moves on the fixed column 3 204. Thus, the movable handrail 205 drives the connecting rod 206 to move on the fixed column 201 and the end of the connecting rod 206 away from the support frame 101 is on the fixed column 3 204. Together, they achieve the storage effect, fixing the movable handrail 205 to the support frame 101, reducing its volume, making it easy to store and change according to needs.

[0038] When storage is required, the connecting column 110 on the support frame 2 103 in the folding mechanism 1, the support frame 2 103 and the support frame 1 101 can be moved inward, thereby driving the linkage column 105 to move upward, which in turn drives the fixed column 104 to move upward, thus achieving the storage function. The connecting column 108 connects the linkage column 105 and the support frame 2 103, while the fixing ring 102 on the support frame 101 connects the support frame 2 103 and the support frame 101, achieving a coordinated movement. The fixed column 104 and the connecting column 108... A ladder plate 106 is connected to the connecting column 3 112. When they move together, the ladder plate 106 moves upward, thus achieving the effect of folding the ladder plate 106. The ladder plate 106 has anti-slip blocks 107 to increase friction, reduce accidents, and ensure personal safety. The bottom of the support frame 1 101 and support frame 2 103 are threadedly connected to casters 111 and anti-slip pads 109, which can be disassembled as needed. Casters 111 can be installed for easy movement, and anti-slip pads 109 can be replaced to increase stability and friction. A fixing block 301 is fixed to the support frame 1 101.

[0039] Fixed block 301 fixes fixed post 4 303 in position. Fixed post 4 303 has rotating rod 2 302 that can move outside of it. Fixed block 301 has spring 304 that can move inside it. At the same time, fixed post 5 306 is located at the bottom of spring 304. Limiting block 305 provides a limiting function for fixed post 5 306 and spring 304. When fixed post 5 306 is inside fixed block 4 307, spring 304 is fixed in position inside fixed block 301 and does not move, thus achieving the limiting effect. When fixed post 5 306 is outside fixed block 4 307, spring 304 drives fixed post 5 306 to move downward, thus not limiting it. Fixed block 4 307 and fixed block 5 308 are fixed together and fixed in position. Fixed post 6 310 connects the end of rotating rod 2 302 away from fixed post 4 303 to fixed block 6 309.
