[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0024] This utility model discloses a convenient building staircase quick assembly structure.
[0025] This utility model provides, for example Figure 1-5 The diagram illustrates a convenient, quick-assembly structure for building stairs, comprising a fixed plate 1, a support plate 2, and treads 3. Two fixed plates 1 are provided, each with a mounting groove 4. Mounting plates 5 are located at both ends of the support plate 2. The support plate 2 and mounting plates 5 are integrated, with the support plate 2 connected to the mounting groove 4 via the mounting plates 5. A slot 10 is provided on the support plate 2, into which the treads 3 are inserted. Vertical plates 11 are provided on the support plate 2, with symmetrical openings on the vertical plates 11. There are two strip grooves 12. Two strip blocks 18 are symmetrically arranged on the bottom outer wall of the step plate 3. The two strip blocks 18 are respectively fitted and connected to the two strip grooves 12. A guide groove 13 is opened on the inner wall of the strip groove 12. A limiting block 14 is fitted and connected in the guide groove 13. A connecting rod 15 is provided on the outer wall of the limiting block 14. The other end of the connecting rod 15 extends through to the outside of the vertical plate 11. A limiting hole 19 is opened on the strip block 18. The size and position of the limiting block 14 and the limiting hole 19 are consistent.
[0026] This utility model discloses a convenient building staircase quick assembly structure. The mounting plate 5 has a first groove 6, and a connecting hole is provided through the bottom inner wall of the first groove 6. The bottom inner wall of the mounting groove 4 has a screw hole 7. The positions of the connecting hole and the screw hole 7 are consistent, which can facilitate the fixing of the support plate 2 and the mounting plate 5 onto the fixing plate 1.
[0027] This utility model discloses a convenient building staircase quick assembly structure. The bottom inner wall of the mounting groove 4 is provided with a second groove 8, and the bottom inner wall of the second groove 8 is provided with a through mounting hole 9, which can facilitate the installation of the fixing plate 1 in the designated position.
[0028] This utility model discloses a convenient building staircase quick-assembly structure. A spring 16 is nested on the connecting rod 15. The spring 16 is pressed between the outer wall of the limiting block 14 and the inner wall of the guide groove 13. Through the elastic force of the spring 16, the limiting block 14 can always be kept in a fitted state with the limiting hole 19, so as to avoid the limiting block 14 from separating from the limiting hole 19 during use and affecting the stability of use.
[0029] This utility model discloses a convenient building staircase quick-assembly structure. One end of the connecting rod 15 extending through to the outside of the vertical plate 11 is fixedly connected to a pull ring 17. A rubber sleeve is nested on the pull ring 17, which can facilitate the movement of the limiting block 14 and improve the overall ease of operation.
[0030] This utility model provides a convenient building staircase quick assembly structure, in which both the limiting block 14 and the strip block 18 are provided with inclined surfaces, and the inclination positions of the two inclined surfaces are consistent, which makes it easy for the strip block 18 to be inserted into the interior of the strip groove 12.
[0031] In use, first install the two fixing plates 1 in the designated positions, then place the mounting plate 5 on the support plate 2 into the mounting groove 4, and then fix the mounting plate 5 to the fixing plate 1 with bolts. Then, align the step plate 3 with the slot 10 and insert it. During the insertion process, the strip block 18 will also enter the interior of the strip groove 12, and the limiting block 14 will enter the interior of the guide groove 13 under the pushing force of the strip block 18. After the step plate 3 is fully inserted, the limiting hole 19 will move to the position of the limiting block 14. At this time, the limiting block 14 has no external force, so it will automatically enter the interior of the limiting hole 19 under the elastic action of the spring 16, thereby providing a limiting effect for the step plate 3. At this point, the overall construction of the staircase is completed.
[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
