Description

Technical Field

[0001] This utility model relates to the field of staircase installation structure technology, and in particular to a detachable modular staircase installation structure. Background Technology

[0002] Traditional staircase installation methods typically involve on-site concrete pouring or the use of monolithic staircase components. These methods have numerous drawbacks. On-site concrete pouring requires significant time and manpower, generates substantial dust and noise pollution during construction, and necessitates a long curing period, severely impacting construction progress. Monolithic staircase components, due to their large size and weight, are extremely inconvenient to transport and handle, and the installation process is also complex, requiring ample installation space and equipment. Furthermore, when damage occurs and repairs or replacements are needed, traditional staircase structures often require complete dismantling or large-scale destructive demolition, resulting in high repair costs and difficulties. As the construction industry increasingly focuses on construction efficiency, environmental protection requirements, and ease of maintenance, developing a modular, detachable staircase installation structure is of significant practical importance.

[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following drawbacks often exist: the staircase occupies a large space if not used; the staircase is used frequently and is prone to wear and tear and damage; if the staircase is not removable, the maintenance of the hidden parts will become extremely difficult; in addition, the non-removable staircase will occupy a large space, making it difficult to move the staircase; therefore, a modular installation structure for a detachable staircase is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of existing technologies where stairs occupy a large amount of space when not in use, stairs are frequently used and are prone to wear and tear and damage, and if stairs are not detachable, maintenance of hidden parts becomes extremely difficult. In addition, non-detachable stairs occupy a large amount of space and make it difficult to move stairs. Therefore, a modular installation structure for detachable stairs is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a detachable modular staircase installation structure, comprising an L-shaped plate, wherein an installation device is provided on the surface of the L-shaped plate, the installation device comprising two support plates, both of which are fixedly connected to the surface of the L-shaped plate, and six round rods fixedly connected to the side of the two support plates that are close to each other, wherein two connecting frames are rotatably connected to the arc surface of the round rods, and a setting rod is rotatably connected to the inner surface of the two connecting frames, and a standing frame is rotatably connected to the arc surface of the setting rod, a handrail frame is fixedly connected to one side of the support plate, and a flat plate is fixedly connected to the side of the two support plates that are close to each other.

[0006] The effect achieved by the above components is as follows: by setting up the installation device, the installation and disassembly of the detachable staircase are achieved, avoiding the problem of occupying a large space when the staircase is not in use. The staircase is used frequently and is prone to wear and tear and damage. If the staircase is not detachable, the maintenance work of the hidden parts will become extremely difficult. It is difficult for maintenance personnel to directly access the faulty parts, and it may be necessary to damage part of the staircase to carry out the maintenance. In addition, the non-detachable staircase will occupy a large space, making it difficult to move the staircase.

[0007] Preferably, two drive rods are fixedly connected to both sides of the L-shaped plate, and a rotating wheel is rotatably connected to the arc surface of the drive rod.

[0008] The effect achieved by the above components is that when the position of the stairs needs to be moved, the use of wheels reduces friction, making it easier to move the stairs.

[0009] Preferably, an elliptical frame is fixedly connected to the side of the drive rod away from the L-shaped plate, a limiting rod is slidably inserted into the inner surface of the elliptical frame, a round block is fixedly connected to one end of the limiting rod, and a limiting groove is formed on the surface of the rotating wheel.

[0010] The effect achieved by the above components is to limit the rotation of the wheel by setting a limit rod, so as to prevent the wheel from rotating on the surface of the drive rod during the use of the staircase.

[0011] Preferably, the limiting rod is provided to limit the rotation of the wheel, preventing the wheel from rotating on the surface of the drive rod during use of the staircase.

[0012] The effect achieved by the above components is that when it is necessary to insert the limiting rod into the inner surface of the limiting groove, the elastic force of the spring will automatically insert the limiting rod into the inner surface of the limiting groove.

[0013] Preferably, the arc surface of the drive rod is rotatably connected to a sector plate, and a groove is provided on one side of the sector plate.

[0014] The effect achieved by the above components is that when the stairs need to be moved, the groove blocks the limit rod, preventing the spring force from pulling the limit rod into the inner surface of the limit groove.

[0015] Preferably, a protective device is provided on one side of the standing frame. The protective device includes three fixing plates, all of which are fixedly connected to one side of the standing frame. Two turning plates are fixedly connected to the side of the fixing plates away from the standing frame. T-shaped plates are slidably connected to the inner surfaces of the two turning plates. A rubber block is fixedly connected to the side of the T-shaped plate away from the fixing plates. Two mounting holes are opened on the surface of the rubber block, and positioning rods are slidably connected to the inner surfaces of the mounting holes.

[0016] The effects achieved by the above-mentioned components are as follows: by setting up protective devices, the user is prevented from falling and getting injured, avoiding accidental falls that could lead to fractures, friction between the user's body and the surface of the stairs that could cause skin damage, or even soft tissue impact that could cause swelling, pain, bruising, and other symptoms. If the user falls and lands on their buttocks, the head may be hit and cause a concussion. The patient may develop a fear of stairs, which could affect their daily life.

[0017] Preferably, a plurality of anti-slip blocks are fixedly connected to one side of the rubber block, and the anti-slip blocks are made of rubber.

[0018] The effect achieved by the above components is that when the user stands on the rubber block, the anti-slip block increases the friction between the sole of the shoe and the rubber block, preventing falls and injuries.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] 1. In this utility model, by setting an installation device, the effect of installing and disassembling a detachable staircase is achieved, avoiding the problem of occupying a large space when the staircase is not in use. Staircases are used frequently and are prone to wear and tear and damage. If the staircase is not detachable, the maintenance work of the hidden parts will become extremely difficult. It is difficult for maintenance personnel to directly access the faulty parts, and it may be necessary to damage part of the staircase to carry out the maintenance. In addition, the non-detachable staircase will occupy a large space, making it difficult to move the staircase.

[0021] 2. In this utility model, by setting up a protective device, the effect of preventing users from falling and getting injured is achieved, avoiding accidental falls that could lead to fractures, friction between the user's body and the surface of the stairs that could cause skin damage, or even soft tissue impact that could cause swelling, pain, bruising, and other symptoms. If the user falls and lands on their buttocks, the head may be hit, causing a concussion. The patient may develop a fear of stairs, which could affect their daily life. Attached Figure Description

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a modular installation structure for a detachable staircase, including an L-shaped plate 1. An installation device 2 is provided on the surface of the L-shaped plate 1. By setting the installation device 2, the detachable staircase can be installed and disassembled, avoiding the problem of large space occupation when the staircase is not in use. Staircases are frequently used and prone to wear and damage. If the staircase is not detachable, maintenance of hidden parts becomes extremely difficult, as maintenance personnel cannot directly access the faulty parts and may need to damage part of the staircase for repair. Furthermore, a non-detachable staircase occupies a large amount of space, making it difficult to move. A protective device 3 is provided on one side of the standing frame 205. By setting the protective device 3, the user is prevented from falling and sustaining injuries, such as fractures, skin abrasions, or soft tissue impacts caused by friction between the user's body and the staircase surface, resulting in swelling, pain, and bruising. If the fall results in a head injury after landing on the buttocks, it can cause a concussion, potentially leading to a fear of stairs and affecting daily life.

[0029] The specific setup and function of the installation device 2 and the protective device 3 will be described in detail below.

[0030] Reference Figure 2 and Figure 3As shown in this embodiment: the installation device 2 includes two support plates 201, both of which are fixedly connected to the surface of the L-shaped plate 1. Six round rods 202 are fixedly connected to the side of the two support plates 201 that are close to each other. Two connecting frames 203 are rotatably connected to the arc surface of the round rods 202. A setting rod 204 is rotatably connected to the inner surface of the two connecting frames 203. A standing frame 205 is rotatably connected to the arc surface of the setting rod 204. A handrail frame 206 is fixedly connected to one side of the support plate 201, and a flat plate 207 is fixedly connected to the side of the two support plates 201 that are close to each other. Two drive rods 208 are fixedly connected to both sides of the L-shaped plate 1. A wheel 209 is rotatably connected to the arc surface of the drive rod 208. When it is necessary to move the position of the stairs, the wheel 209 is used to reduce friction and make it easier to move the stairs. An elliptical frame 210 is fixedly connected to the side of the drive rod 208 away from the L-shaped plate 1. A limiting rod 212 is slidably inserted into the inner surface of the elliptical frame 210. A round block 213 is fixedly connected to one end of the limiting rod 212. A limiting groove 211 is formed on the surface of the rotating wheel 209. The limiting rod 212 limits the rotating wheel 209 to prevent it from rotating on the surface of the drive rod 208 during use. A spring 214 is fitted onto the arc surface of the limiting rod 212. The two ends of the spring 214 are fixedly connected to one side of the elliptical frame 210 and one side of the round block 213, respectively. When the limiting rod 212 needs to be inserted into the inner surface of the limiting groove 211, the elastic force of the spring 214 automatically inserts the limiting rod 212 into the inner surface of the limiting groove 211. A sector plate 215 is rotatably connected to the arc surface of the drive rod 208. A groove 216 is formed on one side of the sector plate 215. When the stairs need to be moved, the groove 216 blocks the limit rod 212, preventing the spring force of the spring 214 from pulling the limit rod 212 into the inner surface of the limit groove 211.

[0031] Reference Figure 4 and Figure 5 As shown, specifically, the protective device 3 includes three fixed plates 31, each fixedly connected to one side of the standing frame 205. Two turning plates 32 are fixedly connected to the side of the fixed plates 31 away from the standing frame 205. T-shaped plates 33 are slidably connected to the inner surfaces of the two turning plates 32. A rubber block 34 is fixedly connected to the side of the T-shaped plate 33 away from the fixed plates 31. Two mounting holes 35 are formed on the surface of the rubber block 34, and positioning rods 36 are slidably connected to the inner surfaces of the mounting holes 35. Several anti-slip blocks 37, made of rubber, are fixedly connected to one side of the rubber block 34. When a user stands on the rubber block 34, the anti-slip blocks 37 increase the friction between the sole of the shoe and the rubber block 34, preventing falls and injuries.

[0032] Working principle: When staff need to use the stairs, first place the L-shaped plate 1 on the ground. Then, place the connecting frame 203 on the arc surface of the round rod 202, rotate the connecting frame 203 on the surface of the round rod 202 until it reaches the appropriate position, and slide the setting rod 204 on the inner surface of the connecting frame 203, causing the standing frame 205 to rotate on the surface of the setting rod 204. With the support of the support plate 201, multiple round rods 202, connecting frames 203, setting rods 204, and standing frames 205 are connected. Users can then stand on the surface of the standing frame 205 one by one, holding onto the surface of the handrail frame 206, and gradually reach the surface of the highest plate 207. When users need to move the stairs, they pull the round block. 213 drives the limiting rod 212 to slide on the inner surface of the elliptical frame 210, and the spring 214 is stretched until the limiting rod 212 disengages from the inner surface of the limiting groove 211. The rotating sector plate 215 rotates on the arc surface of the drive rod 208. When the limiting rod 212 is aligned with the inner surface of the groove 216, the limiting rod 212 is limited, and the staircase can be moved. When it is moved to the appropriate position, the rotating sector plate 215 rotates on the arc surface of the drive rod 208. When the limiting rod 212 moves away from the surface of the sector plate 215, the round block 213 is released, the spring 214 rebounds, and the limiting rod 212 slides on the inner surface of the elliptical frame 210 until the limiting rod 212 enters the inner surface of the limiting groove 211, and the rotating wheel 209 is limited.

[0033] When the staff needs to use the protective device 3, firstly, one side of the T-shaped plate 33 abuts against the fixed plate 31. The T-shaped plate 33 slides between the two turning plates 32 and the fixed plate 31 until it slides from one side of the fixed plate 31 to the other side, thereby causing the rubber block 34 and the anti-slip block 37 on one side of the rubber block 34 to slide. When it slides to the appropriate position, the positioning rod 36 slides along the inner surface of the setting hole 35. When the positioning rod 36 slides to the bottom of the setting hole 35, it limits the rubber block 34 and protects the user. When it is necessary to remove the rubber block 34, the positioning rod 36 slides out along the inner surface of the setting hole 35, and the T-shaped plate 33 slides between the two turning plates 32 and the fixed plate 31 until it slides out from one side of the fixed plate 31, thereby removing the rubber block 34.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
