Description

Technical Field

[0001] This invention relates to the field of prefabricated staircase storage technology, and in particular to an adjustable staircase stacking device. Background Technology

[0002] Precast stairs, as a widely used precast material in the construction field, have brought a lot of convenience to the construction industry. At present, in the field of building industrialization, the production and storage of precast stairs mostly adopt the storage method of supporting square timber on the bottom layer and stacking stairs on the top layer.

[0003] A search of existing technology revealed a "stacking rack for prefabricated stairs that is easy to move," with the publication number "CN217515685U." This device is adjustable according to the length of the prefabricated stairs. However, after use, this device occupies a large space, is not convenient to disassemble and assemble, and has an impact on the construction environment.

[0004] Therefore, an adjustable stair stacking device is proposed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable stair stacking device to solve the above-mentioned problems, thereby improving the issues of occupying a large space after use, being inconvenient to disassemble and assemble, and affecting the construction environment.

[0006] The present invention achieves the above-mentioned objective through the following technical solution: an adjustable stair stacking device, comprising: two supporting base frames, wherein a partition rod is fixedly connected to the upper end of the supporting base frames; an assembly mechanism, wherein the assembly mechanism is installed between the two supporting base frames; wherein the assembly mechanism includes a positioning component installed on the upper end of the supporting base frame, and a connecting and stabilizing component is provided on one side of the positioning component, the connecting and stabilizing component being located at the upper end of the supporting base frame.

[0007] Preferably, the positioning component includes a vertical rod fixedly connected to the upper end of the support base. A retaining strip is slidably connected to the inner wall of the vertical rod. A plurality of first hexagonal holes are opened on one side of the vertical rod adjacent to the retaining strip. The plurality of first hexagonal holes are longitudinally distributed along the surface of the vertical rod. A hexagonal post is slidably connected to the inner wall of one of the first hexagonal holes. The hexagonal post is inserted into the adjacent first hexagonal hole to form a limit. The retaining strip can cooperate with the hexagonal post to form a positioning function.

[0008] Preferably, the connecting and stabilizing assembly includes two hinge rods and a guide strip. The upper ends of the two hinge rods are hinged to each other, and the lower ends of the hinge rods are hinged to hinge seats. A side sliding seat is fixedly connected to one side of the hinge seat, and a slide rail is provided on one side of the side sliding seat. The guide strip is fixedly connected to one side of the vertical rod, and the surface of the guide strip is slidably connected to the inner wall of the slide rail. The arrangement of the guide strip, together with the slide rail provided by the side sliding seat, will allow the two hinge rods to hinge together and, together with the positioning assembly, form triangles at different angles. Due to the stability of the triangle, the stability of the device during use can be improved.

[0009] Preferably, a threaded rod is fixedly connected to the end of the hexagonal column away from the vertical rod, and a threaded sleeve is threadedly connected to the surface of the threaded rod. When the threaded sleeve is rotated, the threaded rod will move horizontally, which will then push the hexagonal column into the first hexagonal hole to form an assembly effect.

[0010] Preferably, the surface of the hexagonal prism is provided with a slot, and the inner wall of the slot engages with the surface of the locking strip. The slot allows the locking strip to be inserted into the slot, thus restricting the displacement of the hexagonal prism.

[0011] Preferably, a support rod is fixedly connected to one side of the hinge seat, and a second hexagonal hole is provided on one side of the support rod. The second hexagonal hole provided in the support rod can guide the hexagonal column and prevent the hexagonal column from rotating easily.

[0012] Preferably, the cross-section of the second hexagonal hole matches the cross-section of the hexagonal prism, and both the cross-section of the second hexagonal hole and the hexagonal prism are regular hexagons.

[0013] The beneficial effects of this invention are:

[0014] 1. The above-mentioned adjustable stair stacking device can be quickly assembled when needed. Through the combination of positioning components and connecting and stabilizing components, the distance between the two supporting base frames can be appropriately adjusted for different stair placement conditions, and a relatively stable positioning effect will be formed on the two supporting base frames, achieving convenient disassembly and assembly and reducing the impact on the construction environment.

[0015] 2. By setting up connecting and stabilizing components and positioning components, the support base frame is limited and will form a similar triangle. Due to the stability of the triangle, the positioning stability of the device can be enhanced. The support rod and the second hexagonal hole form a positioning guide for the hexagonal column, which assists the stable positioning function of the positioning component.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] In practical implementation: such as Figure 1-4 As shown, an adjustable stair stacking device includes: two support bases 1, with a partition rod 2 fixedly connected to the upper end of the support bases 1; and an assembly mechanism 3 installed between the two support bases 1. The assembly mechanism 3 includes a positioning component 31 installed on the upper end of the support bases 1, and a connecting and stabilizing component 32 is provided on one side of the positioning component 31. The connecting and stabilizing component 32 is located at the upper end of the support bases 1.

[0023] like Figures 1-4 As shown, the positioning component 31 includes a vertical rod 311 fixedly connected to the upper end of the support base 1. A retaining strip 312 is slidably connected to the inner wall of the vertical rod 311. A plurality of first hexagonal holes 313 are opened on one side of the vertical rod 311 adjacent to the retaining strip 312. The plurality of first hexagonal holes 313 are longitudinally distributed along the surface of the vertical rod 311. A hexagonal column 314 is slidably connected to the inner wall of one of the first hexagonal holes 313. A threaded rod 315 is fixedly connected to the end of the hexagonal column 314 away from the vertical rod 311. A threaded sleeve 316 is threadedly connected to the surface of the threaded rod 315. A slot 317 is opened on the surface of the hexagonal column 314. The inner wall of the slot 317 engages with the surface of the retaining strip 312.

[0024] This device allows manual rotation of the threaded sleeve 316 to cause two threaded rods 315 to rotate accordingly. Since the ends of the threaded rods 315 are fixedly connected to hexagonal posts 314, these rods rotate synchronously. The second hexagonal hole 327 on the side of the support rod 326 matches and restricts the rotation of the hexagonal post 314. This causes the threaded sleeve 316 to rotate, cooperating with the threaded rods 315 to move horizontally, thereby driving the hexagonal post 314 to rotate in the second hexagonal hole 327 on the side of the support rod 326. The inner wall of the corner hole 327 slides, and then when the end of the hexagonal post 314 enters the interior of the first hexagonal hole 313, the retaining strip 312 can be manually inserted into the inner wall of the vertical rod 311, and the retaining strip 312 will pass through the retaining groove 317, thereby limiting the hexagonal post 314 through the retaining strip 312, ensuring the stability of the distance between the two support bases 1; when it is necessary to store, the two hexagonal posts 314 can be separated from the first hexagonal hole 313 by manually rotating the threaded sleeve 316, thereby achieving the effect of quick assembly;

[0025] like Figures 1-4 As shown, the connecting and stabilizing assembly 32 includes two hinge rods 321 and a guide bar 325. The upper ends of the two hinge rods 321 are hinged to each other, and the lower ends of the hinge rods 321 are hinged to a hinge seat 322. A side sliding seat 323 is fixedly connected to one side of the hinge seat 322. A slide rail 324 is provided on one side of the side sliding seat 323. The guide bar 325 is fixedly connected to one side of the vertical rod 311. The surface of the guide bar 325 is slidably connected to the inner wall of the slide rail 324. A support rod 326 is fixedly connected to one side of the hinge seat 322. A second hexagonal hole 327 is provided on one side of the support rod 326. The cross-section of the second hexagonal hole 327 matches the cross-section of the hexagonal prism 314. The device forms a triangular shape by combining two hinged rods 321, a lower hinged seat 322, and a positioning component 31. Due to the stability of the triangle, the device's stable positioning effect can be improved. The device slides on the surface of the guide bar 325 through the slide rail 324 opened by the side sliding seat 323, which enhances the stability of the distance between the two support bases 1. Furthermore, the device provides positioning guidance for the hexagonal column 314 through the support rod 326 and the second hexagonal hole 327, which assists in the stable positioning effect of the positioning component 31.

[0026] In use, the present invention is assembled by manually rotating the threaded sleeve 316, which drives the two threaded rods 315 to rotate accordingly. Since the threaded rods 315 match the second hexagonal hole 327 opened inside the support rod 326 through the surface of the hexagonal column 314, the rotation of the hexagonal column 314 is restricted. This achieves the effect that the rotation of the threaded sleeve 316 drives the threaded rods 315 to move horizontally. The hexagonal column 314 slides on the inner wall of the second hexagonal hole 327, and the end of the hexagonal column 314 enters the first hexagonal hole 313. The retaining strip 312 is manually inserted into the inner wall of the vertical rod 311. The retaining strip 312 will pass through the retaining groove 317 to form a limit. The two hinged rods 321, the lower hinge seat 322, and the positioning component 31 are combined to form a triangular state. Due to the stability of the triangle, the stable positioning effect of the device is improved.

[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
