[0026] 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.

[0027] Please see Figures 1 to 6 A modular furniture piece that is easy to assemble and disassemble includes stair treads 100 and footboards 200. Two stair treads 100 are arranged sequentially and mate with the top connecting parts of a children's bed, fixing the two stair treads 100 to the side of the children's bed. Multiple footboards 200 are arranged in a stepped pattern between the two stair treads 100. U-shaped frames 101 are fixedly installed on the inner side of each of the two stair treads 100, and the bottom ends of the footboards 200 are respectively engaged with the grooves of the two U-shaped frames 101. The sides of the footboards 200 respectively contact and engage with the inner sides of the two stair treads 100. After the footboards 200 are placed between the two stair treads 100, the footboards 200 are kept stable by the support of the U-shaped frames 101.

[0028] A fixing structure 300 is installed in the groove 201 on the bottom side of the tread 200. The fixing structure 300 includes a fixing block 301 and a threaded rod 302. The fixing block 301 is fixedly installed in the middle of the groove 201. The middle section of the threaded rod 302 is rotatably connected to the fixing block 301 through a bearing 306, which is installed in a hole on the fixing block 301. The two threaded sections of the threaded rod 302 are respectively threadedly connected to threaded sleeves 303. The two threaded sleeves 303 are respectively fixedly connected to insert blocks 304 at opposite ends. The two insert blocks 304 can slide in the groove 201, and the U-shaped frame 101 does not affect the movement of the insert blocks 304. The outer ends of the two insert blocks 304 are respectively inserted into the insertion holes 102 opened on the inner side of the two stair treads 100. After placing the tread 200 between the two stair treads 100, the installer rotates the threaded rod 302 from below the tread 200. As the threaded rod 302 rotates, the two threaded sleeves 303 move away from each other, pushing the two inserts 304 away from each other until the outer ends of the two inserts 304 are inserted into the corresponding holes 102, thus fixing the tread 200 between the two stair treads 100. For disassembly, the threaded rod 302 is rotated in the opposite direction, causing the two threaded sleeves 303 to move relative to each other, which in turn causes the two inserts 304 to move relative to each other, so that the outer ends of the two inserts 304 leave the holes 102, allowing the installer to remove the tread 200.

[0029] This utility model, by setting up a fixing structure 300, a U-shaped frame 101 and a socket 102, has the advantage of first fixing two stair treads 100, then placing the corresponding treads 200 and fixing the treads 200, so that no workers need to keep the components stable during the installation process. It solves the problem that the operation method of having workers hold and keep one side of the stair tread 100 and the tread 200 stable before installing the other side of the stair tread 100 is more troublesome when installing stairs, and maintaining stability is a relatively laborious process.

[0030] Specifically, a rotating sleeve 305 is fitted onto the threaded screw 302, and the rotating sleeve 305 has a hexagonal structure. When the installer rotates the threaded screw 302, the rotation of the rotating sleeve 305 can drive the rotation of the threaded screw 302, providing the installer with a point of force for rotation.

[0031] Furthermore, guide strips 202 are fixedly provided on the front and rear walls of the groove 201, and the insert block 304 is I-shaped, with the grooves on the front and rear walls of the insert block 304 slidingly engaging with the two guide strips 202 respectively. When the insert block 304 is moved, the insert block 304 slides along the groove 201, and at the same time, the insert block 304 also moves along the guide strips 202, keeping the movement of the insert block 304 stable.

[0032] Working principle: The stair treads 100 are connected to the top connecting parts of the children's bed, and the two stair treads 100 are fixed to the side of the children's bed. The footboard 200 is placed between the two stair treads 100. The installer rotates the rotating sleeve 305 from below the footboard 200. The threaded screw 302 rotates accordingly. As the threaded screw 302 rotates, the two threaded sleeves 303 move away from each other, pushing the two inserts 304 to move away from each other along the groove 201. The inserts 304 also move along the guide strip 202 until the outer ends of the two inserts 304 are inserted into the corresponding holes 102, fixing the footboard 200 between the two stair treads 100, thus completing the installation of the stairs.

[0033] During disassembly, rotate the rotating sleeve 305 in the opposite direction, and the positive and negative threaded screws 302 rotate in the opposite direction. The two threaded sleeves 303 move relative to each other, which drives the two inserts 304 to move relative to each other, so that the outer ends of the two inserts 304 leave the insertion hole 102, and the installer removes the pedal 200.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
