[0002] This utility model relates to the field of building construction technology, and in particular to a reusable protective device for prefabricated staircases. [Background Technology]

[0004] With the development of the construction industry, prefabricated staircases have been widely used in the construction field due to their high efficiency and environmental friendliness. However, there are some problems with the use of staircase safety panels during the construction process, especially the inconvenience of turnover and the limited installation methods. These problems affect construction efficiency and safety performance to some extent.

[0005] Traditional stair railings are often designed as a single piece, making them difficult to transport and store. On prefabricated building construction sites, the limited space makes the turnover and storage of these railings a challenge. This not only increases transportation and handling costs but also affects construction progress.

[0006] Traditional protective panels are typically installed using bolts or welding, methods that are not only cumbersome but also have limited applicability. Different materials and structures of stairs may require different installation tools and methods, undoubtedly increasing installation difficulty and cost. Furthermore, the limited installation method restricts the flexibility and versatility of the protective panels, failing to meet the needs of various construction scenarios.

[0007] The purpose of this utility model is to solve the problems of inconvenient turnover and limited installation methods of existing stair protection panels. [Utility Model Content]

[0009] The purpose of this utility model is to solve the problems of inconvenient turnover and limited installation methods of existing stair protection panels. This utility model adopts the following technical solution: This utility model is achieved through the following technical solution:

[0012] As described above, in a prefabricated staircase reusable protective device, a plurality of first rubber pads are provided between the rotating shaft and the rotating block, and the first rubber pads are sleeved on the outside of the rod.

[0013] As described above, in a prefabricated staircase reusable protective device, a plurality of second rubber gaskets are provided between the second hexagonal block and the nut, and the second rubber gaskets are sleeved on the outside of the rod.

[0019] In the prefabricated reusable protective device for stairs described above, the diagonal length of the hexagonal groove is consistent with the diameter length of the rotating shaft.

[0020] Implementing the embodiments of this utility model has the following beneficial effects:

[0021] 1. In this utility model, the protective device adopts a flat design, allowing it to be easily folded or stacked when not in use, forming a compact form.

Detailed Implementation Methods

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] like Figures 1 to 9 As shown in the figure, this utility model embodiment proposes a prefabricated reusable protective device for stairs, including a horizontal plate mechanism 1 and a flip plate mechanism 2. The horizontal plate mechanism 1 includes a horizontal plate 101, and the flip plate mechanism 2 includes a flip plate 201. A through groove 106 is provided on one side of the horizontal plate 101, and hexagonal grooves 204 are provided at both ends of one side of the flip plate 201. A damping pivot mechanism 3 is installed in the through groove 106, and one end of the damping pivot mechanism 3 is disposed in the hexagonal groove 204. The horizontal plate 101 is hinged to the flip plate 201 through the damping pivot mechanism 3. Both the horizontal plate 101 and the flip plate 201 are provided with mounting components. The mounting components include magnet blocks 202 disposed at the bottom of the horizontal plate 101 and the flip plate 201, and / or through holes 104 opened on the horizontal plate 101 and the flip plate 201.

[0038] The horizontal plate 101 of the horizontal plate mechanism 1 is placed on the tread of the stairs. The long and wide sides of the horizontal plate 101 are designed to match the long and wide sides of the stair tread. The flip plate 201 of the flip plate mechanism 2 is installed on the stair riser, thereby protecting the stairs. The horizontal plate mechanism 1 and the flip plate mechanism 2 can be installed on the upper floor through the installation components.

[0039] The damping function in the damping shaft mechanism 3 helps the flap 201 maintain a stable posture. During the flipping process, the damping mechanism provides appropriate resistance to the flap 201, preventing the flap 201 from easily shaking or changing position due to external forces. When used in conjunction with the magnet block 202, the flap 201 can maintain its stability even if it is simply magnetically connected to the stairs by the magnet block 202, preventing the flap 201 from flipping randomly and enhancing the overall stability of the protective device.

[0040] Optionally, in some embodiments, the mounting components include magnet blocks 202 disposed at the bottom of the horizontal plate 101 and the flip plate 201, and through holes 104 formed on the horizontal plate 101 and the flip plate 201. The magnet blocks 202 installed at the bottom of the horizontal plate 101 and the flip plate 201 enable the horizontal plate 101 and the flip plate 201 to be firmly attached to the iron prefabricated stair treads and risers, making them less prone to slippage. For other non-iron prefabricated staircases, magnetic connectors or iron connectors can be pre-embedded in the treads and risers of the steps, thereby realizing the installation of the protective device on non-iron staircases. The through holes 104 formed on the horizontal plate 101 and the flip plate 201 provide an additional fixing method for the protective device. Users can use bolts adapted to the through holes 104 to fix the protective device on the staircase as needed.

[0041] Optionally, in some embodiments, the mounting components include magnet blocks 202 disposed at the bottom of the horizontal plate 101 and the flip plate 201.

[0042] Optionally, in some embodiments, the mounting components include through holes 104 formed in the cross plate 101 and the flap 201.

[0043] like Figures 1 to 9 As shown, a slot 107 is provided on one side of the through groove 106. The damping rotating shaft mechanism 3 includes a first hexagonal block 302 and a rotating shaft 301. The first hexagonal block 302 is fixedly connected to one end of the rotating shaft 301. A locking block 303 is fixedly connected to one side of the first hexagonal block 302. The shape of the locking block 303 matches the shape of the slot 107. A rod 309 is fixedly connected to one end of the rotating shaft 301. A rotating block 305 and a second hexagonal block 306 are sleeved on the rod 309. The rotating block 305 and the second hexagonal block 306 are... Block 306 is fixedly connected. Both the rotating block 305 and the second hexagonal block 306 are rotatably connected to the rod body 309. The rod body 309 is fitted with a nut 308, which is threadedly connected to the rod body 309. A plurality of first rubber gaskets 304 are provided between the rotating shaft 301 and the rotating block 305, and the first rubber gaskets 304 are fitted outside the rod body 309. A plurality of second rubber gaskets 307 are provided between the second hexagonal block 306 and the nut 308, and the second rubber gaskets 307 are fitted outside the rod body 309.

[0044] The locking block 303 engages within the locking groove 107, thereby maintaining the stability of the rotating shaft 301 and preventing its rotation. When the angle of the flap 201 needs adjustment, the flap drives the second hexagonal block 306 to rotate. Even though the locking block 303 is fixed within the locking groove 107, restricting the overall rotation of the rotating shaft 301, the rotating block 305 and the second hexagonal block 306 can still rotate freely relative to the rod 309. When the nut 308 rotates along the thread direction of the rod 309, it compresses the second rubber gasket 307 and the second hexagonal block 306, thereby generating pressure on the first rubber gasket 304 and the rotating shaft 301 through the rotating block 305. The elastic deformation of the rubber gasket provides a certain degree of damping effect for the rotating shaft 301. The stronger the pressure of the nut 308 on the second rubber gasket 307 and the second hexagonal block 306, the greater the resistance to the rotation of the second hexagonal block 306.

[0045] When installing the damping shaft mechanism 3, simply insert the damping shaft mechanism 3 into the through groove 106 and the hexagonal groove 204, and insert the locking block 303 into the locking groove 107 to complete the installation. It is easy to install and remove.

[0046] like Figures 1 to 9 As shown, the top surfaces of the horizontal plate 101 and the flip plate 201 are provided with a plurality of protrusions 102 by stamping, and the bottom surfaces of the horizontal plate 101 and the flip plate 201 are provided with a plurality of grooves formed by the stamping protrusions 102, and the magnet block 202 is disposed in the groove.

[0047] The stamped protrusions 102 not only enhance the structural strength of the horizontal plate 101 and the flip plate 201, enabling them to withstand greater pressure and impact, thus improving the stability and durability of the entire device, but also provide additional anti-slip functionality. The grooves formed by the stamped protrusions 102, whose shape and position correspond to the protrusions on the top surface, are spaces created by the compression of the sheet material during the stamping process. The presence of these grooves facilitates the installation of other components. The magnet 202, installed within the grooves, does not occupy additional space, ensuring that the bottoms of the horizontal plate 101 and the flip plate 201 remain flat, preventing any protrusions or unevenness caused by the installation of the magnet 202. This design is not only aesthetically pleasing but also makes the entire device easier and more convenient to install.

[0048] like Figures 1 to 9 As shown, the top surface of the horizontal plate 101 is provided with a plurality of grooves 103.

[0049] The grooves 103 are used for drainage. These grooves 103 form low-lying areas on the surface of the horizontal plate 101. When water droplets, rainwater, or other liquids fall on the horizontal plate 101, they will naturally flow into these grooves 103 and accumulate. Subsequently, the accumulated water can be smoothly drained from the surface of the horizontal plate 101 through the guiding effect of the grooves 103, preventing water from stagnating on the horizontal plate 101, thus ensuring the cleanliness and dryness of the horizontal plate 101, and also preventing corrosion, mildew, or other adverse effects caused by water accumulation on the surface of the board.

[0050] like Figures 1 to 9 As shown, a first plug 105 is fitted inside the through hole 104, and the through hole 104 is a countersunk hole.

[0051] The first plug 105 is fitted inside the countersunk hole, further ensuring the sealing and stability of the through hole. The tight fit between the plug and the countersunk hole effectively prevents dust, moisture, or other impurities from entering the through hole, thus extending the lifespan of the board. The countersunk hole design prevents the plug from protruding from the board surface, ensuring overall aesthetics and preventing potential collisions and scratches. The countersunk hole design also facilitates screw installation. During installation, using countersunk screws ensures the screw head is fully recessed into the plug, avoiding the problem of protruding screw heads. This not only makes the overall appearance cleaner but also reduces the risk of loosening or snagging shoes due to protruding screw heads.

[0052] like Figures 1 to 9 As shown, a second plug 108 is fitted inside one end of the through groove 106.

[0053] The second plug 108 can prevent dust and water from entering the through groove 106, further protecting the damping shaft mechanism 3, extending the service life of the damping shaft mechanism 3, and also avoiding the risk of the damping shaft mechanism 3 sliding out of the through groove 106.

[0054] like Figures 1 to 9 As shown, an inclined section 203 is provided on the side where the flap 201 is hinged to the horizontal plate 101. The inclined section 203 is an inclined surface that gradually narrows from the bottom of the flap 201 to the top side of the flap 201.

[0055] Setting the tilt section 203 can increase the flipping range of the flap 201, making it easier for the flap 201 to exceed the 90-degree limit when flipping, thus adapting to steps at different angles.

[0056] like Figures 1 to 9 As shown, the diagonal length of the hexagonal groove 204 is the same as the diameter length of the rotating shaft 301.

[0057] The diagonal length of the hexagonal groove 204 is consistent with the diameter length of the shaft 301, which maximizes the side surface area of ​​the second hexagonal block 306, thereby allowing the installation of a larger second rubber pad 307. The larger second rubber pad 307 can further increase the damping effect of the damping shaft mechanism 3.

[0058] Specifically, the working principle of this utility model is as follows:

[0059] In use, the horizontal plate 101 is placed on the stair tread, and its bottom magnet 202 is tightly attracted to the iron staircase or pre-embedded magnetic connectors, achieving a preliminary fixing effect. The flip plate 201 is installed on the stair riser, similarly using its bottom magnet 202 to attract and fix it to the stair riser or pre-embedded connectors. The inclined section 203 makes it easier for the flip plate to exceed the 90-degree limit when flipping, thus adapting to different angles of the steps. For non-iron staircases, the protective device can also be securely installed through pre-embedded iron connectors. This magnetic attraction method greatly simplifies the installation process. The through hole 104 provides an additional fixing method for the protective device; users can use bolts compatible with the through hole 104 to fix the protective device to the staircase as needed. Users can even use glue to attach the device to the staircase, offering a variety of installation options. The flip plate 201 and the horizontal plate 101 are hinged together by a damping pivot mechanism 3, which allows the flip plate 201 to flip freely. The various components in the damping shaft mechanism 3 work together to provide appropriate damping for the rotation of the flap 201. When the flap 201 is subjected to external force, the damping mechanism can reduce its swaying amplitude, so that the flap 201 can remain stable even if it is simply magnetically connected to the staircase by the magnet block 202, preventing the flap 201 from flipping over randomly and enhancing the overall stability of the protective device.

[0060] Thanks to the hinged design of the horizontal plate 101 and the flip plate 201, the device can be easily folded or stacked together when not in use, forming a compact, flat shape. This shape not only reduces the space occupied by the device during transportation but also lowers transportation costs and improves transportation efficiency. At the same time, the flat design also makes the device more space-saving when stored, facilitating inventory management and turnover for users.

[0061] In summary, this utility model solves the problems of inconvenient turnover and limited installation methods of existing stair protection panels.

[0062] It should be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information. In addition, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0063] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
