Figures 1 to 4 are the first embodiment of the present invention. As shown in Figures 1 to 4, the present invention has a tripod 100 for increasing and adjusting the height of the elevated floor, including: a supporting tube 1, which can stand upright on the ground, and the top end of the supporting tube 1 has a top end opening 11; an anti-lift connector 2, which is provided on the top end opening 11 of the supporting tube 1 with at least one fixing structure 21, and the central part of the anti-lift connector 2 has a first screw hole 22; a height-increasing connector 3, which has a first external thread The first outer threaded tube 31 and the first inner threaded seat 32 are arranged above the first outer threaded tube 31, and the first outer threaded tube 31 is screwed on the first screw hole 22 of the anti-lift connector 2; a support seat 4 is composed of a support plate 41 and a screw 42 arranged at the bottom of the support plate 41, and the screw 42 is screwed on the first inner threaded seat 32; by this structure, the purpose of conveniently adjusting the height and conveniently increasing the adjustable height can be achieved. It will be explained in detail below.

The supporting tube body 1 can stand upright on the ground, and the top end of the supporting tube body 1 has a top end opening 11.

The anti-lift connector 2 is provided on the top opening 11 of the supporting tube body 1 with at least one fixing structure 21. The fixing structure 21 includes a fixing bolt 212 and a welding nut 213. The welding nut 213 is welded to the top tube wall of the supporting tube body 1. The central part of the anti-lift connector 2 has a first screw hole 22. More specifically, the anti-lift connector 2 can include a plate body 201 and a positioning tube body 202 provided at the bottom of the plate body 201. The plate body 201 is provided on the top tube wall of the supporting tube body 1, and the positioning tube body 202 is provided in the top opening 11 of the supporting tube body 1.

The height-increasing connector 3 is composed of a first externally threaded tube 31 and a first internally threaded seat 32 disposed above the first externally threaded tube 31. More specifically, the first externally threaded tube 31 has a first externally threaded portion 311, and the first internally threaded seat 32 further includes a second screw hole 33, which can extend downward from the first internally threaded seat 32 and penetrate the first externally threaded tube 31. The first externally threaded tube 31 is screwed into the first screw hole 22 of the anti-lift connector 2, and the screw rod 42 rotates in the second screw hole 33 to facilitate the coarse adjustment of the height of the elevated floor. The thickness T1 of the first internally threaded seat 32 can increase the height of the scaffolding of the elevated floor. For example, by using a first internally threaded seat 32 with a thickness of about 2 cm, the height of the scaffolding of the elevated floor can be increased by about 2 cm. The user can select the first internal threaded seat 32 of corresponding thickness according to the height that the tripod needs to increase.

The support seat 4 is composed of a support plate 41 and a screw 42 disposed at the bottom of the support plate. The screw 42 is screwed on the first internal thread seat 32 so that the floor unit of the elevated floor can be supported by the support plate 41 to form an elevated floor (not shown in the figure). In other words, the height-increasing connector 3 is disposed between the support tube 1 and the support seat 4 to increase the overall adjustable height. In addition, the first internal thread seat 32 can be in the shape of a hexagonal column, so as to facilitate rotation and positioning with tools such as a wrench.

The aperture D1 of the second screw hole 33 of the first internally threaded seat 32 can be smaller than the aperture D2 of the first screw hole 22 of the anti-lift connector 2, so that the bottom end of the screw rod 42 can rotate through the second screw hole 33 of the first internally threaded seat 32, the first externally threaded tube 31 and the first screw hole 22 of the anti-lift connector 2, and extend into the interior of the supporting tube body 1, thereby increasing stability. In addition, when the floor unit has not been installed, the rotating support seat 4 can first roughly adjust the height of the top surface of the support plate 41, and then adjust the height of the floor unit supported by it. Therefore, the aperture D1 of the second screw hole 33 of the first internal threaded seat 32 is smaller than the aperture D2 of the first screw hole 22 of the anti-lift connector 2, so that the design of rotating the screw rod 42 in the second screw hole 33 can ensure that the screw rod 42 can roughly adjust the height adjustment range of the elevated floor. Furthermore, compared with the conventional technology not shown in the figure, the conventional screw rod is directly screwed into the first screw hole of the conventional anti-lift connector, and the present invention adopts the design of the anti-lift connector 2 with a first screw hole 22 having a larger aperture than the outer diameter of the screw rod 42, which can facilitate the installation of the height-increasing connector 3.

The side wall of the first internal threaded seat 32 of the height-increasing connector 3 may have an opening 321, and a fixing nut 322 and a bolt 323 are provided on the outer side of the side wall of the first internal threaded seat 32. The screw hole of the fixing nut 322 is aligned with the opening 321 of the first internal threaded seat 32, and the bolt 323 is screwed on the fixing nut 322. The end of the bolt 323 passes through the fixing nut 322 and the opening 321 of the first internal threaded seat 32 and is abutted against the thread of the screw rod 42, so that after the height of the height-increasing connector 3 is finely adjusted, the height-increasing connector 3 is securely locked and fixed. When the floor is set on the support seat 4, the bolt 323 can be loosened. By rotating the anti-lift connector 2, the screw 42 can be driven to fine-tune the height of the top surface of the support plate 41, and then the height of the floor unit supported by it can be fine-tuned. With this structure, when a plurality of tripods 100 with height-adjusting functions are used to form an elevated floor (not shown in the figure), the floor units supported by each tripod 100 can be conveniently adjusted to the same horizontal plane.

FIG5 shows a second embodiment of the present invention. As shown in FIG5, at least one connecting member 5 may be provided between the anti-lifting connector 2 and the height-increasing connector 3, and the connecting member 5 is composed of a second externally threaded tube 51 and a second internally threaded seat 52 disposed above the second externally threaded tube 51. More specifically, the second externally threaded tube 51 has a second externally threaded portion 511, and the second internally threaded seat 52 further includes a third screw hole 53, and the third screw hole 53 may extend downward from the second internally threaded seat 52 and penetrate the second externally threaded tube 51. The second externally threaded tube 51 is screwed on the first screw hole 22 of the anti-lifting connector 2, and the first externally threaded tube 31 is screwed on the third screw hole 53 of the second internally threaded seat 52, so as to further increase the overall adjustable height. In addition, the second internal threaded seat 52 can be a hexagonal column shape like the first internal threaded seat 32, so as to facilitate rotation and positioning. Among them, the thickness T2 of the second internal threaded seat 52 can further increase the height of the scaffolding at the height of the elevated floor. For example, using a second internal threaded seat 52 with a thickness of about 3 cm, the height of the scaffolding at the height of the elevated floor can be increased by about 3 cm. The user can select the second internal threaded seat 52 with the corresponding thickness according to the height that the scaffolding needs to increase.

FIG6 shows the third embodiment of the present invention. As shown in FIG6, more than two connecting connectors 5 and connecting connectors 5 are provided between the anti-lifting connector 2 and the height-increasing connector 3. Each connecting connector 5 is connected in series up and down, and the second external threaded tube 51 of the upper connecting connector 5 is screwed on the third screw hole 53 of the second internal threaded seat 52 of the lower connecting connector 5; the second external threaded tube 51 at the bottom of each connecting connector 5 is screwed on the first screw hole 22 of the anti-lifting connector 2; the first external threaded tube 31 is screwed on the third screw hole 53 of the second internal threaded seat 52 at the top of each connecting connector 5, so as to further increase the overall height of the scaffolding that can be adjusted to increase the height of the elevated floor by about 6 cm.

The above are examples of the present invention, which are only for the purpose of explanation and should not be used to limit the meaning of the present invention. In other words, all kinds of changes and designs made according to the scope of the listed patent application should be included in the patent scope of the present invention.
