[0025] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] Please refer to Figure 1-5 This application provides a straightener (hereinafter referred to as "the straightener") that can prevent the countertop from sinking. The straightener 2 is fixedly connected to the wall 3 on one hand, and fixedly connected to the suspended countertop 1 on the other hand. If the suspended countertop 1 sinks, the straightener 2 can lift it to a preset height.

[0027] The straightener 2 includes:

[0028] A lead screw 21 and a nut 22 are threadedly connected to the lead screw 21. When the lead screw 21 rotates, it drives the nut 22 to move on the lead screw 21.

[0029] The drive motor 24, the first pulley 23, the second pulley 25, and the transmission belt (not shown in the figure) are connected by the transmission belt, and the first pulley 23 is fixedly mounted on the lead screw 21. The second pulley 25 is fixedly mounted on the drive motor 24. The first pulley 23 and the second pulley 25 are connected by the transmission belt, so that the drive motor 24 drives the lead screw 21 to rotate.

[0030] The system includes a first connecting plate 26, a second connecting plate 27, and a third connecting plate 28. The lead screw 21 is fixedly mounted on the first connecting plate 26 and is also rotatable relative to it. The first connecting plate 26 and the second connecting plate 27 are fixedly connected together. The third connecting plate 28 is connected to the nut 22. The first connecting plate 26 is fixedly connected to the wall. In this application, the first connecting plate 26 is fixedly connected to the wall by expansion screws or bolts. The second connecting plate 27 is at a certain angle to the ground, and this angle is usually acute. That is, the angle between the lead screw 21 and the ground is acute, meaning the lead screw 21 is inclined to the ground. Thus, when the nut 22 moves on the lead screw 21, it causes the suspended tabletop 1 to rise. Furthermore, the third connecting plate 28 is fixedly connected to the suspended tabletop 1, so that when the nut 22 moves, it causes the third connecting plate 28 to move, thereby raising the suspended tabletop 1 to a preset height.

[0031] Please refer to some embodiments of this application. Figure 1-5 The straightener 2 also includes a first fixed connecting block 210, a second fixed connecting block 211, a first bearing 212, and a second bearing 213. The first fixed connecting block 210 is fixedly connected to a preset position of the second connecting plate 27, and the second fixed connecting block 211 is fixedly connected to a preset position of the first connecting plate 26. The first bearing 212 is fixedly embedded in the first fixed connecting block 210, and the second bearing 213 is fixedly embedded in the second fixed connecting block 211. The lead screw 21 is fixedly installed with the first bearing 212 on one hand and with the second bearing 213 on the other hand, so that the lead screw 21 is fixedly installed on the first connecting plate 26 on one hand, and can rotate relative to the first connecting plate 26 on the other hand.

[0032] Please refer to some embodiments of this application. Figure 1-5 The straightener 2 also includes a fourth connecting plate 29 and a fifth connecting plate 214. The fifth connecting plate 214 and the third connecting plate 28 are fixedly connected together. The fourth connecting plate 29 and the nut 22 are fixedly connected together. The fourth connecting plate 29 and the fifth connecting plate 214 are fixedly connected together, so that when the nut 22 moves on the lead screw 21, it drives the third connecting plate 28 to move. Therefore, when the third connecting plate 28 moves, it drives the suspended platform to rise. The fixed connection methods between the fourth connecting plate 29 and the fifth connecting plate 214, and between the fifth connecting plate 214 and the third connecting plate 28, include one or more combinations of welding, snap-fit, screw connection, bolt connection, or riveting. In this application, as... Figure 1-5The fourth connecting plate 29 is fixedly sleeved on the nut 22, thereby fixing the fourth connecting plate 29 and the nut 22 together. Of course, the fourth connecting plate 29 and the nut 22 can also be fixedly connected together by welding, screws or bolts.

[0033] Please refer to some embodiments of this application. Figure 1-5 The second connecting plate 27 is provided with an elongated sliding through hole 270, which extends through the second connecting plate 27 and has a preset length. The fourth connecting plate 29 is placed in the sliding through hole 270 and is movable within the sliding through hole 270, so that when the nut 22 moves on the lead screw 21, it drives the fourth connecting plate 29 to move within the sliding through hole 270. In this application, the sliding through hole 270 has a preset length, which is related to the distance the nut 22 moves on the lead screw 21; that is, the length of the sliding through hole 270 is related to the height to which the suspended platform 1 rises.

[0034] Please refer to some embodiments of this application. Figure 1-5 The straightener 2 also includes a sliding rail 215 and a sliding block 216. The sliding rail 215 is fixedly mounted on the second connecting plate 27, and the sliding block 216 is fixedly mounted on the fifth connecting plate 214. The sliding block 216 is slidably connected to the sliding rail 215, allowing it to slide on the sliding rail 215. Thus, when the nut 22 moves on the lead screw 21, it drives the fourth connecting plate 29 to move, which in turn drives the fifth connecting plate 214 to move. The fifth connecting plate 214 then drives the sliding block 216 to move on the sliding rail 215. The purpose of providing the sliding block 216 and the sliding rail 215 in this application is to make the movement of the nut 22 on the lead screw 21 more stable, and also to make the movement of the third connecting plate 28 more stable, thereby making the lifting of the suspended platform 1 more stable.

[0035] Please refer to some embodiments of this application. Figure 1-5The sliding through hole 270 on the second connecting plate 27 has a first limiting inner wall 271 and a second limiting inner wall 272, which are disposed opposite to each other and constitute a part of the sliding through hole 270. When the fourth connecting plate 29 moves in the sliding through hole 270, the first limiting inner wall 271 and the second limiting inner wall 272 prevent the fourth connecting plate 29 from continuing to move in the sliding through hole 270. In this application, the distance between the first limiting inner wall 271 and the second limiting inner wall 272 is the distance that the fourth connecting plate 29 can move in the sliding through hole 270.

[0036] Please refer to some embodiments of this application. Figure 1-5 The drive motor 24 is fixedly mounted on the first connecting plate 26, and the lead screw 21 is located outside the sliding through hole 270 of the second connecting plate 27.

[0037] like Figure 6 As shown, the suspended platform 1 connected to the straightener 2 includes a platform 11, a first protective plate 12, a second protective plate 13, and a connecting plate 14. The first protective plate 12 is perpendicular to and fixedly connected to the platform 11, and the second protective plate 12 is also perpendicular to and fixedly connected to the platform 11. The connecting plate 14 is fixedly connected to both the platform 11 and the second protective plate 13. The connecting plate 14 can be fixedly connected to the platform 11 and the second protective plate 13 by screws, bolts, or riveting. The third connecting plate 28 of the straightener 2 provided in this application is fixedly connected to the connecting plate 14 of the suspended platform 1, so that when the third connecting plate 28 moves, it drives the entire suspended platform 1 to move. The third connecting plate 28 of the straightener 2 and the connecting plate 14 of the suspended platform 1 in this application are fixedly connected by screws or bolts.

[0038] The straightener provided in this application, which prevents the platform from sagging, has the advantages of simple structure and easy assembly and disassembly. Secondly, the inclusion of a drive motor, lead screw, and nut eliminates the need for manual lifting of the suspended platform, saving time and effort and achieving a high degree of automation. Thirdly, the lead screw and nut work together to ensure stable and smooth lifting of the platform. Finally, a sliding through-hole with a limiting inner wall restricts the maximum movement distance of the fourth connecting plate, preventing the platform from rising indefinitely. This straightener allows for arbitrary adjustment of the platform height, is concealed and secure, and offers advantages such as easy installation and significantly reduced platform replacement costs.

[0039] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly.
