DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] When implementing: Figure 1-4 As shown, an assembly adjustable stair stacking device comprises: two support frames 1, the upper ends of the support frames 1 are fixedly connected with a partition rod 2; an assembly mechanism 3, the assembly mechanism 3 is installed between the two support frames 1; wherein the assembly mechanism 3 comprises a positioning assembly 31 installed at the upper ends of the support frames 1, a connection and stabilization assembly 32 is provided on one side of the positioning assembly 31, and the connection and stabilization assembly 32 is located at the upper ends of the support frames 1;

[0023] like Figure 1-Figure 4 As shown, the positioning assembly 31 includes a vertical rod 311 fixedly connected to the upper end of the supporting base frame 1, the inner wall of the vertical rod 311 is slidably connected with a clamping strip 312, a side of the vertical rod 311 adjacent to the clamping strip 312 is provided with a plurality of first hexagonal holes 313, and the plurality of first hexagonal holes 313 are longitudinally distributed along the surface of the vertical rod 311, and 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 one 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 clamping groove 317 is provided on the surface of the hexagonal column 314, and the inner wall of the clamping groove 317 is clamped with the surface of the clamping strip 312;

[0024] The device can manually rotate the threaded sleeve 316 so that when the threaded sleeve 316 rotates, the two threaded rods 315 are driven to rotate accordingly. At this time, since the ends of the threaded rods 315 are fixedly connected to the hexagonal columns 314, the following threaded rods 315 rotate synchronously. Since the second hexagonal holes 327 on the side of the support rod 326 match the hexagonal columns 314 to limit the rotation of the hexagonal columns 314, when the threaded sleeve 316 rotates, it cooperates with the threaded rods 315 to form a horizontal movement, thereby driving the hexagonal columns 314 in the second hexagonal holes 327. The inner wall of the corner hole 327 slides, and then when the end of the hexagonal column 314 enters the interior of the first hexagonal hole 313, the clamping strip 312 can be manually inserted into the inner wall of the vertical rod 311, and the clamping strip 312 can pass through the clamping groove 317, so that the clamping strip 312 forms a limiting effect on the hexagonal column 314, ensuring the distance between the two supporting base frames 1 is stable; when it is necessary to store, the threaded sleeve 316 can be manually rotated to separate the two hexagonal columns 314 from the first hexagonal hole 313, thereby achieving a quick assembly effect;

[0025] like Figure 1-Figure 4 As shown, the connection and stabilization component 32 includes two hinged rods 321 and a guide bar 325. The upper ends of the two hinged rods 321 are hinged to each other, and the lower end of the hinged rod 321 is hinged with a hinge seat 322. One side of the hinge seat 322 is fixedly connected to a side sliding seat 323, and one side of the side sliding seat 323 is provided with a slideway 324. The guide bar 325 is fixedly connected to one side of the vertical rod 311, and the surface of the guide bar 325 is slidably connected to the inner wall of the slideway 324. One side of the hinge seat 322 is fixedly connected to a support rod 326, and one side of the support rod 326 is provided with a second hexagonal hole 327, and the cross-section of the second hexagonal hole 327 matches the cross-section of the hexagonal column 314. The device is formed into a triangle-like state by combining two mutually hinged hinged rods 321, a hinged seat 322 at the lower end and a positioning component 31. Due to the stability of the triangle, the stable positioning effect of the device can be improved. The device slides on the surface of the guide bar 325 through the slide 324 opened by the side sliding seat 323, thereby enhancing the stability of the distance between the two supporting base frames 1. The device also forms a positioning guide for the hexagonal column 314 through the support rod 326 and the second hexagonal hole 327, thereby assisting the stable positioning effect of the positioning component 31.

[0026] When the present invention is in use, the threaded sleeve 316 is manually rotated during assembly to drive the two threaded rods 315 to rotate accordingly. Since the threaded rod 315 matches 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 limited, so that the threaded sleeve 316 rotates to drive the threaded rod 315 to move in the horizontal direction. 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 clamping strip 312 is manually inserted into the inner wall of the vertical rod 311, and the clamping strip 312 will pass through the clamping groove 317 to form a limit. The two mutually hinged hinged rods 321 and the hinged seat 322 at the lower end and the positioning assembly 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] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
