[0031] Reference Figure 1 to Figure 2The utility model proposes a floor support device, comprising: a base 1, a support assembly 2 is arranged at the top of the base 1, and one side of the support assembly 2 is rotatably connected to the base 1 through a hinge 3; a lifting assembly 4 is arranged on the side of the support assembly 2 away from the hinge 3, and the lifting assembly 4 includes a lifting seat 41, and the lifting seat 41 is rotatably connected to the support assembly 2, and the lifting seat 41 is provided with two symmetrical oblique holes 42, and the oblique holes 42 are slidably connected with an adjusting block 43, and the adjusting block 43 is penetrated by a bidirectional screw rod 44, and the two ends of the bidirectional screw rod 44 are rotatably connected to the base 1, and the adjusting block 43 is driven to slide in the oblique hole 42 by rotating the bidirectional screw rod 44, so as to adjust the height of the lifting seat 41 to change the inclination of the support assembly 2.

[0032] In the above embodiment, the base 1 supports the support component 2 and the lifting component 4. The bottom side of the support component 2 is rotatably connected to the base 1 through a hinge 3. The hinge 3 can be in the form of a hinge. Two symmetrical oblique holes 42 are opened on the lifting seat 41. The oblique holes 42 have a certain vertical height. Each oblique hole 42 is slidably connected with an adjustment block 43. The adjustment blocks 43 are also symmetrically arranged. The bidirectional screw rod 44 passed through the adjustment block 43 has different thread directions on different adjustment blocks 43. Therefore, the bidirectional screw rod 44 can be rotated to drive the adjustment block 43 to slide in the oblique hole 42 relative to the lifting seat 41, so that the lifting seat 41 can be lifted and lowered to achieve a change in height, thereby changing the inclination of the support component 2.

[0033] To summarize, the two adjustment blocks 43 are driven simultaneously by the bidirectional screw rod 44 to slide toward or away from each other in the inclined hole 42, thereby driving the lifting seat 41 to rise and fall. Combined with one side of the support component 2 being hinged to the base 1 through the hinge 3, the lifting of the lifting seat 41 can flexibly adjust the inclination of the support component 2 to adapt to the needs of inclined surfaces of various angles. Only through the built-in adjustment mechanism, the support of the inclined floor can be achieved without adding additional structural parts, thereby greatly enhancing the stability of the support device.

[0034] In one embodiment, the lifting assembly 4 also includes two symmetrically arranged guide rails 45, which are arranged at the top of the base 1, and the top of the guide rails 45 is slidably connected with a sliding seat 46, both ends of the bidirectional screw rod 44 are passed through the sliding seat 46, and the bidirectional screw rod 44 is rotatably connected to the sliding seat 46.

[0035] In the above embodiment, the two symmetrically arranged guide rails 45 in the lifting assembly 4 are firmly mounted on the top of the base 1 to ensure stable passive sliding during the adjustment process. The top of the guide rail 45 is slidably connected to a sliding seat 46, and the sliding seat 46 can slide along the guide rail 45. Both ends of the bidirectional screw rod 44 are passed through and rotatably connected to the sliding seat 46. When the bidirectional screw rod 44 is rotated, the position of the lifting seat 41 will change, causing the support assembly 2 to be lifted. The change in angle drives the lifting seat 41 to move horizontally, and then move precisely along the guide rail 45 through the sliding seat 46. In addition, the use of the sliding seat 46 and the guide rail 45 not only enhances the stability of the structure, but also further improves the accuracy and efficiency of the adjustment.

[0036] In one embodiment, two opposite sides of the sliding seat 46 are fixedly connected with guide rods 47 , the guide rods 47 are parallel to the bidirectional screw rod 44 , and the guide rods 47 are disposed through the adjustment block 43 .

[0037] In the above embodiment, the guide rods 47 fixedly connected to the two opposite sides of the sliding seat 46 are parallel to the bidirectional screw rod 44. The guide rods 47 are arranged through the adjustment block 43, and provide additional guidance and support when the adjustment block 43 slides along the oblique hole 42, ensuring that the adjustment block 43 can slide smoothly in the oblique hole 42, avoiding the deviation or shaking that may be caused by the rotation of the bidirectional screw rod 44. In addition, the coordinated use of the guide rods 47 and the adjustment block 43 further enhances the stability of the support device and the accuracy of adjustment, making the entire support assembly 2 more stable and reliable during the adjustment process, and suitable for various complex inclined floor support requirements.

[0038] refer to Figure 3 In one embodiment, the support assembly 2 includes a support seat 21 and a telescopic arm 22, the hinge 3 is provided on one side of the support seat 21, the support seat 21 is rotatably connected to the base 1 through the hinge 3, the side of the support seat 21 away from the hinge 3 is rotatably connected to the lifting seat 41, the first end of the telescopic arm 22 is rotatably connected to the support seat 21, and the second end of the telescopic arm 22 is slidably connected to the support seat 21.

[0039] In the above embodiment, one side of the support seat 21 is rotatably connected to the base 1 through the hinge 3, ensuring that the support assembly 2 can smoothly adjust the tilt angle when needed. The side of the support seat 21 away from the hinge 3 is rotatably connected to the lifting seat 41, so that the lifting action of the lifting seat 41 can directly act on the support seat 21, thereby achieving effective adjustment of the inclination of the support assembly 2. The telescopic arm 22 further increases the adjustable range of the support assembly 2. The telescopic arm 22 is specifically a scissor-type lifting structure, which actually has four connection ends, one end is relatively fixed, and the other end is relatively sliding. Specifically, the first end of the telescopic arm 22 is a relatively fixed end, which is rotatably connected to the support seat 21, and the second end is slidably connected to the support seat 21, so that the height of the telescopic arm 22 can be flexibly adjusted as needed, further improving the practicality and stability of the support assembly 2.

[0040] In one embodiment, the support assembly 2 also includes a support plate 23, which is arranged directly above the support seat 21, and the third end of the telescopic arm 22 is rotatably connected to the support plate 23, and the fourth end of the telescopic arm 22 is slidably connected to the support plate 23.

[0041] In the above embodiment, anti-skid lines or anti-skid pads can be provided on the support plate 23 to enhance the friction between the floor and the support plate 23, and prevent the floor from sliding or shifting during the support process. The support plate 23 not only increases the load-bearing area of ​​the support assembly 2, making the support more uniform and stable, but also provides a flatter support surface for the floor, avoiding the inclination of the floor caused by the uneven support point. The third end of the telescopic arm 22 is a relatively fixed end, which is rotatably connected to the support plate 23, and the fourth end is slidably connected to the support plate 23, so that the telescopic arm 22 can flexibly adjust the height according to different floors, adapt to different support requirements, and further improve the adaptability and stability of the support assembly 2. In summary, by adding the support plate 23 and adjusting the connection method of the telescopic arm 22, the floor support device of this embodiment further enhances the load-bearing capacity and the protection effect on the floor on the basis of adjusting flexibility and stability, and is suitable for a wider range of inclined floor support requirements.

[0043] In the above embodiment, the adjustment assembly 5 at the top of the support seat 21 provides a more direct and flexible way to adjust the telescopic arm 22. By rotating the screw 51, the pusher 52 sleeved on the screw 51 can move along the axial direction of the screw 51, thereby driving the second end of the telescopic arm 22 rotatably connected to the pusher 52 to slide on the support seat 21, so as to adjust the length of the telescopic arm 22, thereby changing the overall support height of the support assembly 2.

[0044] In one embodiment, symmetrical extension plates 6 are provided on opposite sides of the support plate 23, and the extension plates 6 are rotatably connected to the support plate 23. Force-bearing rods 7 are rotatably connected to the opposite sides of the extension plates 6, and the bottom ends of the force-bearing rods 7 are detachably connected to the support plate 23.

[0045] In the above embodiment, the symmetrical extension plates 6 on both sides of the support plate 23 can increase the support area of ​​the support plate 23 when needed, improve the stability of the support assembly 2, and the rotation connection between the extension plates 6 and the support plate 23 allows the extension plates 6 to be flexibly adjusted in angle or disassembled to adapt to floors of different shapes and sizes. The force rods 7 can enhance the load-bearing capacity of the extension plates 6. Through the detachable connection between the force rods 7 and the support plate 23, the extension of the support area can be conveniently achieved, or the extension plates 6 can be folded by disassembling the force rods 7.

[0046] In one embodiment, a clamping member 8 is provided on the side of the lifting seat 41 facing away from the supporting seat 21, a guide protrusion is provided at the bottom end of the clamping member 8, and a guide groove corresponding to the guide protrusion is provided at the base 1, and the clamping member 8 is slidably connected to the base 1, wherein when the lifting seat 41 is lifted, the clamping member 8 can slide to the bottom end of the lifting seat 41 and press against the lifting seat 41.

[0047] In the above embodiment, the clamping member 8 is arranged on the side of the lifting seat 41 away from the support seat 21, and the guide protrusion arranged at the bottom thereof is used to provide a guiding function when sliding is required, and forms a tight guiding mechanism with the corresponding guide groove on the base 1. When the lifting seat 41 is lifted due to the rotation of the bidirectional screw 44, the clamping member 8 can be further operated to slide along the guide groove, so that it slides to the bottom end of the lifting seat 41 and tightly presses against the lifting seat 41, effectively preventing the lifting seat 41 from accidentally falling when subjected to external pressure or vibration, thereby ensuring the stability and safety of the support assembly 2.

[0049] In the above embodiment, the setting of the counterweight 9 effectively balances the torque that may be generated when the lifting seat 41 tilts after lifting, making the support assembly 2 more stable during the adjustment process. The matching design of the positioning protrusion and the guide groove ensures the stable installation of the counterweight 9 on the base 1, avoiding the influence of the stability of the support assembly 2 on the movement of the counterweight 9. In addition, the detachable connection between the counterweight 9 and the base 1 not only facilitates the handling during transportation and installation, but also allows the counterweight 9 to be quickly disassembled when not needed, so as to meet the support requirements in different occasions.
