Description

Technical Field

[0001] The utility model relates to the technical field of teaching devices, in particular to an inclination angle adjusting device for an experimental board. Background Art

[0002] In teaching and experimental research, the experimental board is often used as the basic platform for experiments, such as slope experiments, etc., to study physical phenomena such as gravity, friction, and energy conversion. Usually, during the experiment, the experimental board needs to be clamped and fixed, and the angle is frequently adjusted to achieve the corresponding experimental purpose.

[0003] In the traditional experiment process, there are two ways to fix the experimental board. One is manual construction. The experimenter may directly hold the experimental board by hand to build the experimental platform, which is troublesome to operate and the angle adjustment is not accurate, resulting in poor experimental results. The other is the experimental board clamping device. Although it is more accurate and convenient to fix the experimental board, it is cumbersome to operate when frequently adjusting the inclination angle. It is necessary to release the fixation and then adjust the angle, with low experimental efficiency. Moreover, it is not convenient for one person to operate, and component damage may occur due to improper operation, affecting the experimental accuracy and safety. Summary of the Utility Model

Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0019] Second, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures, or characteristics that may be included in at least one implementation manner of the present utility model. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an independent or selectively mutually exclusive embodiment with other embodiments.

[0020] Referring to Figures 1-3 , this embodiment provides an experimental board inclination angle adjusting device. By arranging a rotary clamping module 2 on the connecting shaft 13, the device can clamp and fix the experimental board and can adjust the angle, with simple and safe operation.

[0021] An experimental board inclination angle adjusting device includes a pair of oppositely arranged adjusting bases 1 and a rotary clamping module 2 arranged on the adjusting base 1. The adjusting bases 1 are symmetrically arranged in the horizontal direction. This symmetrical design helps to improve the balance and coordination of the overall structure, and by assembling the adjusting bases 1, experimental boards of different sizes and weights can be adapted. The adjusting base 1 includes a base 11, a support plate 12 vertically arranged on the top of the base 11, and a connecting shaft 13 arranged on the support plate 12. The connecting shaft 13 is parallel to the base 11. The rotary clamping module 2 includes a rotary component and a clamping component parallel to the base 11 arranged on the rotary component. The rotary component includes a connecting shaft sleeve 21 and a rotary block 23 for adjusting the angle. The connecting shaft sleeve 21 is sleeved on one end of the connecting shaft 13 away from the support plate 12, and one end of the rotary block 23 is sleeved on the outer wall of the connecting shaft sleeve 21. The clamping component includes a locking clamping plate 24 for fixing the experimental board. By rotating the rotary block 23 to adjust the inclination angle of the locking clamping plate 24, the inclination angle of the experimental board can be adjusted. The rotary block 23 and the locking clamping plate 24 are fixedly connected, so the two are linked. The locking clamping plate 24 only needs to be fixed once, and subsequently, according to the experimental requirements, only the rotary block 23 needs to be adjusted, with simple and convenient operation.

[0022] Specifically, the rotary block 23 includes a rotary plate 231. One end of the rotary plate 231 is rotatably sleeved on the outer wall of the connecting shaft sleeve 21. One side of the rotary plate 231 is fixedly connected to the locking clamping plate 24 parallel to the base 11. A fixing hole is opened in a part of the connecting shaft sleeve 21 extending out of the rotary plate 231. After the connecting shaft sleeve 21 is sleeved on the connecting shaft 13, it is fixed by bolts at the fixing hole.

[0023] Among them, the connecting shaft sleeve 21 has a shell-shaped cylindrical structure.

[0024] Furthermore, the rotating block 23 also includes a hinge block 232 and a pry bar 233. The rotating plate 231 is connected to the hinge block 232 on one side away from the locking clamp 24. A hinge hole is provided on the upper part of the hinge block 232. One end of the pry bar 233 passes through the hinge hole and is inserted into the connecting shaft 13 for limiting. A torsion spring is arranged between the place where the pry bar 233 is inserted into the hinge hole and the hinge hole. When the experimental angle needs to be adjusted, the pry bar 233 is disengaged from the connecting shaft 13 by bends. The rotating plate 231 can be rotated to release the pry bar 233. The torsion spring is applied to restore the pry bar 233 to its original state and insert it into the connecting shaft 13.

[0025] Furthermore, a slewing bearing 22 for rotating the slewing plate 231 is arranged between the connecting shaft sleeve 21 and the slewing plate 231 , the inner wall of the slewing bearing 22 is fixedly connected to the connecting shaft sleeve 21 , the outer wall of the slewing bearing 22 is fixedly connected to the slewing plate 231 , and an annular groove for connecting the slewing bearing 22 is provided on the connecting shaft sleeve 21 .

[0026] Furthermore, an oblique groove 211 is provided from the outer wall of the connecting shaft jacket 21 to the inner wall, forming an angle with the outer wall of the connecting shaft jacket 21. The oblique groove 211 is used to clamp the slewing bearing 22 arranged outside the connecting shaft jacket 21. The connecting shaft jacket 21 is made of elastic material. The oblique groove 211 is provided on the top of the connecting shaft jacket 21 to reserve space so that the connecting shaft jacket 21 can be deformed at the oblique groove 211 when fixed. When it is sleeved on the connecting shaft 13 for fixing, the bolt is against the outer wall of the connecting shaft 13. The tighter the bolt is, the more the oblique groove 211 of the connecting shaft jacket 21 will open outward, so that the annular groove on the connecting shaft jacket 21 fits more closely with the inner ring of the slewing bearing 22.

[0027] Furthermore, at least one limiting groove for limiting the pry rod 233 is formed on the outer wall of the connecting shaft 13 in the circumferential direction around the central axis.

[0028] Each limiting groove corresponds to an angle, and the experimental board can be adjusted to a corresponding angle by inserting the pry bar 233 into different limiting grooves, and the operation is convenient and accurate.

[0029] Furthermore, a locking hole is provided on the locking clamping plate 24. When in use, the test board is inserted into the locking hole and the test board is clamped by inserting bolts.

[0030] In the utility model, the device is easy to assemble and has a wider range of applications. The distance between the two adjustment bases 1 can be adjusted according to the size of the experimental board. The experimental board can be fixed on the device by locking the clamping plate 24. The pry bar 233 is then moved to rotate the rotating plate 231 to the vicinity of the limit groove of the corresponding angle, and then the pry bar 233 is inserted therein for limiting. The operation is convenient and efficient.

[0031] The parts not specifically described in the above specification are all prior arts or can be achieved by prior arts. Moreover, the specific implementation cases described in the present utility model are only the preferred implementation cases of the present utility model, and are not used to limit the implementation scope of the present utility model.
