[0037] like Figure 1-3 As shown, this utility model provides a lifting test device for a study desk, including a motor 100 and a drive shaft 200 that is connected to the power output shaft of the motor 100.

[0038] The drive shaft 200 has a transmission part 210 at its power output end. This transmission part 210 can cooperate with the power input element of the height-adjustable study desk to drive the power input element to rotate. The power input element can be the power input gear of the gearbox of the height-adjustable study desk, the power input shaft of the power input gear, or the power input shaft of the height-adjustable study desk itself.

[0039] Specifically, in use, the motor 100 drives the drive shaft 200 to rotate, and the drive shaft 200 drives the power input element to rotate, thereby achieving the purpose of driving the height-adjustable study desk to rise and fall, and thus achieving the purpose of detecting the height-adjustable study desk.

[0040] The lifting test device for the study desk provided by this utility model has a simple structure and reasonable design. The motor 100 drives the drive shaft 200 to rotate, and the drive shaft 200 drives the power input element of the lifting study desk to rotate, thereby achieving the purpose of lifting test of the lifting study desk. No manual cranking is required, which improves the testing efficiency.

[0041] like Figure 3As shown, it also includes a mounting plate 300, a drive wheel 410, a driven wheel 420, and a transmission element 430.

[0042] The motor 100 and the drive shaft 200 are mounted on the mounting plate 300, and the drive shaft 200 is rotatably connected to the mounting plate 300.

[0043] The drive wheel 410 is rotatably mounted on the mounting plate 300 and is drive-connected to the power output shaft of the motor 100. The drive wheel 410 can be coaxially mounted on the power output shaft of the motor 100, or it can be mounted on one side of the power output shaft of the motor 100 and drive-connected via a gear structure, synchronous belt structure, or other transmission structure. In this embodiment, the drive wheel 410 is coaxially mounted on the power output shaft of the motor 100 to simplify the structure.

[0044] The driven wheel 420 is rotatably mounted on the mounting plate 300 and is connected to the drive shaft 200 via a transmission mechanism. The driven wheel 420 can be coaxially mounted on the drive shaft 200, or it can be mounted on one side of the drive shaft 200 and connected via a transmission structure such as a gear structure or a synchronous belt structure. In this embodiment, the driven wheel 420 is coaxially mounted on the drive shaft 200 to simplify the structure.

[0045] The transmission element 430 is annular and is sleeved on the driving wheel 410 and the driven wheel 420, and can rotate as the driving wheel 410 and / or the driven wheel 420 rotate. Specifically, the transmission element 430 can be a transmission belt, a synchronous belt, a transmission chain, etc. In this embodiment, the transmission element 430 is a transmission belt.

[0046] like Figure 1 As shown, it also includes a sliding seat 500 and a first locking bolt 600.

[0047] The sliding seat 500 is movably mounted on the mounting plate 300. Both the driven wheel 420 and the drive shaft 200 are rotatably mounted on the sliding seat 500, and both can move synchronously with the sliding seat 500. Preferably, the mounting plate 300 is provided with a support plate 900 for supporting the motor 100.

[0048] The first locking bolt 600 is used to lock the position of the sliding seat 500, and the mounting plate 300 is provided with a first strip hole 310 for the first locking bolt 600 to pass through.

[0049] Specifically, the first locking bolt 600 can either pass through the first slotted hole 310 and the sliding seat 500 in sequence and then be threadedly connected to the nut, or it can pass through the first slotted hole 310 and then be threadedly connected to the threaded hole in the sliding seat 500. In this embodiment, the first locking bolt 600 passes through the first slotted hole 310 and then is threadedly connected to the sliding seat 500.

[0050] Preferably, there are multiple first locking bolts 600 to improve the stability of locking the position of the sliding seat 500. In this embodiment, there are four first locking bolts 600.

[0051] In use, loosen the first locking bolt 600 as needed to move the sliding seat 500, thereby changing the position of the drive shaft 200. This allows for adaptive adjustment of the drive shaft 200 position based on the power input element of the target height-adjustable learning table, improving the versatility of the entire testing device. Tightening the first locking bolt 600 locks the position of the sliding seat 500.

[0052] like Figure 3 As shown, the motor 100 and the driving wheel 410, the drive shaft 200 and the driven wheel 420 are respectively arranged on both sides of the mounting plate 300. The mounting plate 300 is provided with a second strip hole 320 that is adapted to the drive shaft 200 so that the drive shaft 200 can move together with the sliding seat 500.

[0053] Optionally, both the first strip hole 310 and the second strip hole 320 are arc-shaped holes. Preferably, the centers of the first strip hole 310 and the second strip hole 320 are both on the axis of the drive wheel 410, so that when the drive shaft 200 is moved, the tension of the transmission element 430 can be guaranteed without the need to add an additional tensioning mechanism to guarantee the tension of the transmission element 430.

[0054] like Figure 1 As shown, it also includes a second locking bolt 700, which is used to lock the position of the motor 100. The mounting plate 300 is provided with a third strip hole 330 through which the second locking bolt 700 passes.

[0055] Specifically, the second locking bolt 700 can either pass through the third strip hole 330 and the motor 100 in sequence and then be threadedly connected to the nut to lock the position of the motor 100, or it can pass through the third strip hole 330 and then be threadedly connected to the motor 100 to lock the position of the motor 100.

[0056] In use, loosening the second locking bolt 700 allows the position of the motor 100 to be moved, thereby adaptively adjusting the tension of the rotating element. Tightening the second locking bolt 700 locks the position of the motor 100.

[0057] Preferably, multiple second locking bolts 700 are provided to improve the stability of locking the motor 100. In this embodiment, four second locking bolts 700 are provided.

[0058] like Figure 1 , 2 As shown, it also includes a protective cover 800, which covers the driving wheel 410, driven wheel 420, and transmission element 430, thereby concealing the driving wheel 410, driven wheel 420, and transmission element 430 to prevent personnel from being pinched during inspection. The protective cover 800 is fixedly connected to the mounting plate 300. In this embodiment, the protective cover 800 and the mounting plate 300 are detachably connected, for example, by bolts or by a snap-fit ​​structure.

[0059] like Figure 1 As shown, the protective cover 800 is provided with a fourth strip hole 810, which corresponds to the first strip hole 310, so that the first locking bolt 600 can be rotated without removing the protective cover 800, thereby facilitating the adjustment of the position of the drive shaft 200.

[0060] Specifically, in use, the entire device is fixed to the target study table using a clamp. At the same time, the transmission part 210 of the drive shaft 200 is inserted into the power input element of the study table, and the motor 100 is started. By controlling the forward and reverse rotation of the motor 100, the purpose of driving the study table to rise and fall is achieved. It is easy to operate and has high detection efficiency.
