[0025] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this application proposes an adjustable raised floor, including a stage frame 1, with a floor 2 laid on the stage frame 1, and further including: first insert rods 9, with multiple first insert rods 9 spaced apart on the floor 2; insert cylinders 4, with multiple insert cylinders 4 spaced apart on the stage frame 1; double-ended connecting cylinders 5, with one or more double-ended connecting cylinders 5 between corresponding first insert rods 9 and insert cylinders 4 to change the relative height of the floor 2; second insert rods 51, with a second insert rod 51 at one end of the double-ended connecting cylinder 5, and the other end of the double-ended connecting cylinder 5 adapted to the second insert rod 51 or the first insert rod 9; first spring nut 42, with the first spring nut 42 screwed into the insert cylinder 4, and the first spring nut 42 adapted to the first insert rod 9 or the second insert rod 51; and second spring nut 52, with the second spring nut 52 screwed into the other end of the double-ended connecting cylinder 5, and the second spring nut 52 adapted to the first insert rod 9 or the second insert rod 51.

[0026] The stage frame 1 includes several connecting beams, and a floor 2 spans across two adjacent connecting beams. The connecting beams and the floor 2 are mature existing technologies and are not the core inventive points of this application. Therefore, no specific restrictions are placed on the specific structure of the connecting beams and the floor 2.

[0027] The first insert 9 and the second insert 51 each include an integrally formed connecting part, a rod part, and a plug 8. The connection between the rod part and the plug 8 forms a first abutment surface. The first spring nut 42 and the second spring nut 52 each include a nut part and a plurality of spring pieces. The spring pieces are circumferentially spaced at the ends of the nut part. The nut part and the spring pieces are integrally formed. The end of the spring piece away from the nut part is provided with a second abutment surface. The insert 4 is provided with an internal thread that matches the external thread of the nut part of the first spring nut 42 to form a connection between the insert 4 and the first spring nut 42. The other end of the double-ended connecting cylinder 5 is provided with an internal thread that matches the external thread of the nut part of the second spring nut 52 to form a connection between the double-ended connecting cylinder 5 and the second spring nut 52. During the process of connecting the first insert 9 to the first spring nut 42 or the second spring nut 52, or connecting the second insert 51 to the first spring nut 42 or the second spring nut 52, the plug 8 is inserted downwards to expand the spring, and the spring undergoes elastic deformation. When the widest part of the plug 8 passes the spring, the spring returns to its original shape under its own elastic force, so that the first abutting surface abuts against the second abutting surface.

[0028] In this embodiment, four first insert rods 9 are provided on a floor 2. The stage frame 1 also has four inserts 4 adapted to the first insert rods 9 at preset positions where the floor 2 is installed. When the height requirement of the floor 2 is at its lowest, the first insert rod 9 of the floor 2 is directly inserted into the corresponding insert 4, and when the first abutment surface abuts with the second abutment surface, the end face of the floor 2 abuts with the end face of the insert 4. When the height requirement of the floor 2 is relatively low, the insert rod of the floor 2 is inserted into a double-ended connecting tube 5, and when the first abutment surface abuts with the second abutment surface, the end face of the floor 2 abuts with the end face of the double-ended connecting tube 5. The second insert rod 51 of the double-ended connecting tube 5 is inserted into the insert 4, and when the first abutment surface abuts with the second abutment surface, the end face of the double-ended connecting tube 5 abuts with the end face of the insert 4. When the height requirement of the floor 2 is relatively high, two or more double-ended connecting tubes 5 need to be installed between the corresponding first insert rod 9 and insert 4. It is important to note that the second insert rod 51 of the double-ended connecting cylinder 5 is inserted into the second spring nut 52, and when the first abutting surface abuts against the second abutting surface, the two adjacent double-ended connecting cylinders 5 abut against each other. The pressure is borne by the cylinder body of the double-ended connecting cylinder 5 and the insert 4, and the pull-out force is borne by the first insert rod 9, the second insert rod 51, the first spring nut 42, and the second spring nut 52, thus achieving a temperature connection between the floor 2 and the stage frame 1.

[0029] Specifically, during the installation of floor 2, according to the stage design requirements, one, zero, one, or more double-ended connecting tubes 5 are installed between the first insert rod 9 of floor 2 and the corresponding insert 4 of the stage frame 1 to change the height of floor 2 to meet the stage design requirements. Furthermore, the connections between the first insert rod 9 and the insert 4, the first insert rod 9 and the double-ended connecting tube 5, the double-ended connecting tube 5 and the double-ended connecting tube 4 are all achieved through plug-in connections, making the connection operation simple and requiring minimal manpower.

[0030] See Figure 4 and Figure 5 As shown, in some embodiments, a limiting part 41 is also included, with both the insert 4 and the double-ended connecting cylinder 5 having a limiting part 41. The limiting part 41 is used to limit the insertion depth of the first spring nut 42 or the second spring nut 52.

[0031] In this embodiment, the connecting part of the second insert rod 51 is provided with an external thread, the double-ended connecting cylinder 5 is provided with a matching internal thread, the second insert rod 51 is screwed into the double-ended connecting cylinder 5, and a limiting platform is provided inside the double-ended connecting cylinder 5 to limit the screwing depth of the second insert rod 51.

[0032] See Figure 4 and Figure 5 As shown, in some embodiments, a guide portion 7 is also included, with guide portions 7 provided at the ends of both the first insertion rod 9 and the second insertion rod 51. Guide portions 7 are provided on the plugs 8 of both the first insertion rod 9 and the second insertion rod 51, and the provision of guide portions 7 facilitates better expansion of the spring contacts by the plugs 8.

[0033] See Figure 4 and Figure 5 As shown, in some embodiments, it further includes: a first connecting hole 11, wherein the floor 2 is provided with a first connecting hole 11 for connecting the first insert rod 9; the connecting part of the first insert rod 9 is provided with an external thread, and the first connecting hole 11 is provided with an internal thread, wherein the first insert rod 9 is connected to the first connecting hole 11 by screwing. A second connecting hole, wherein the stage frame 1 is provided with a second connecting cylinder 4. The cylinder 4 can be connected to the second connecting hole by screwing or welding.

[0034] See Figure 1 and Figure 3 As shown, in some embodiments, it further includes a reinforcing member 3, which is provided on the stage frame 1. The reinforcing member 3 is provided between two adjacent connecting beams of the stage frame 1, thereby increasing the strength of the stage frame 1.

[0035] See Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, it further includes: a plurality of disassembly holes 6, which are circumferentially spaced on the insert 4 and the double-ended connecting tube 5. When disassembly is required, a pulling force is applied, and the springs on the first spring nut 42 or the second spring nut 52 are pulled through the disassembly holes 6 to disconnect them from the plug 8.
