[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0027] like Figures 1 to 8 As shown, a detachable and foldable control exercise device includes a learning machine body 1, a magnetic sheet 3 is fixedly connected to the middle of the back of the learning machine body 1, a mounting plate 2 is connected to one side of the magnetic sheet 3, a circular magnet 4 corresponding to the position of the magnetic sheet 3 is fixedly connected to the middle of the mounting plate 2, a back plate 5 is fixedly connected to the back of the mounting plate 2, both sides of the bottom of the back plate 5 are fixedly connected to fixed blocks 6, a rotating shaft 7 is fixedly connected between the two fixed blocks 6, a connecting block 8 is rotatably connected to the outer wall of the rotating shaft 7, a supporting plate 9 is fixedly connected to the outer wall of the connecting block 8, and a limiting component for providing a limiting function to the supporting plate 9 is connected to one side of the fixed block 6.
[0028] like Figure 1 As shown, the detachable and foldable control practice device in the utility model is similar to the existing learning machine structure, such as an English learning machine disclosed in the patent publication number CN214705010U. The main improvement of the utility model is that the bracket of the learning machine is detachable, such as Figures 1 to 8 As shown, when a detachable and foldable comparison and practice device in the utility model is in use, when it is necessary to use the learning machine body 1 on the desktop, the user places the support plate 9 on the desktop, and then rotates the learning machine body 1, so that the learning machine body 1, the mounting plate 2 and the back plate 5 rotate around the rotating shaft 7 to an angle suitable for the user's learning, and then uses the limiting device to fix the support plate 9 and the fixing block 6, and the learning machine body 1 can be used for foreign language comparison and practice; when the user needs to use the learning machine body 1 by hand, the learning machine body 1 can be bent along the gap between the learning machine body 1 and the mounting plate 2, so that the magnetic suction sheet 3 and the circular magnet 4 are separated, and the user can remove the learning machine body 1, and then hold the learning machine body 1 by hand for comparison and practice; when storing the comparison and practice device as a whole, the support plate 9 and the back plate 5 can be folded, so as to reduce the space occupied by the comparison and practice device as a whole, so that the user can carry the comparison and practice device conveniently.
[0029] By arranging a magnetic sheet 3 on the learning machine body 1, a circular magnet 4 on the mounting plate 2, and a support plate 9 on the connecting block 8, and utilizing the adsorption effect between the magnetic sheet 3 and the circular magnet 4, the user can quickly disassemble the learning machine body 1, and switch the control practice device as a whole from a desktop use state to a handheld use state, thereby facilitating the user to hold the learning machine body 1 for control practice, which brings convenience to the user; at the same time, through the rotatable and foldable design of the support plate 9, the compact storage of the support structure is achieved, which brings convenience to the user to store and carry the control practice device as a whole.
[0030] like Figure 1 As shown, the limit assembly includes a limit block 10, an insertion rod 11, a rotating block 12, a slider 15, a threaded rod 17, a connecting column 18 and a fixed rod 20. One end of the limit block 10 is fixedly connected to both sides of the support plate 9, and the other end of the limit block 10 is fixedly connected to the insertion rod 11. One end of the insertion rod 11 is fixedly connected to the rotating block 12. A rotating groove 13 corresponding to the position of the rotating block 12 is opened in the fixed block 6, and a sliding groove 14 is opened on one side of the rotating groove 13. The slider 15 is slidably connected to the sliding groove 14. A threaded groove 16 is opened on one side of the slider 15. The threaded groove 16 is threadedly connected with a threaded rod 17, one end of the threaded rod 17 is fixedly connected to a connecting column 18, a connecting groove 19 corresponding to the position of the connecting column 18 is opened in the rotating block 12, and one end of the connecting column 18 is fixedly connected to the fixed rod 20. A connecting hole 21 corresponding to the position of the fixed rod 20 is opened at one end of the limit block 10, and one end of the fixed rod 20 is located outside the limit block 10.
[0031] Specifically, the cross-sections of the slider 15 and the slide groove 14 are set in a hexagonal, rectangular or other shape that is not easy to rotate; when the user needs to fix the learning machine body 1 after adjusting the angle, the user can rotate the fixing rod 20, and the fixing rod 20 will drive the threaded rod 17 to rotate through the connecting column 18, and the rotation of the threaded rod 17 will drive the slider 15 to rotate. Since the slider 15 cannot rotate in the slide groove 14, the slider 15 will move in the slide groove 14 along the threaded rod 17, and the fixing rod 20 is continuously rotated so that the slider 15 and the rotating block 12 are against each other, providing fixation for the rotating block 12 and the limit block 10. Since the slider 15 and the fixed block 6 cannot rotate, the fixed block 6 and the limit block 10 cannot rotate, thereby ensuring that the back plate 5, the mounting plate 2 and the learning machine body 1 will not rotate, thereby improving the stability of the learning machine body 1 during use; when the support plate 9 needs to be folded, only the fixing rod 20 needs to be rotated in the opposite direction to separate the slider 15 from the rotating block 12, cancel the fixation of the limit block 10, and the user can then rotate the support plate 9 to fold it.
[0032] like Figure 4 , Figure 5 and Figure 8As shown, one end of the fixing rod 20 located outside the limiting block 10 is fixedly connected to a knob 22 , and the outer wall of the knob 22 is fixedly connected to anti-skid particles.
[0033] Specifically, the knob 22 can bring convenience for the user to rotate the fixed rod 20, increase the contact area between the user's fingers and the fixed rod 20, and facilitate the user to tighten the limit block 10. The design of anti-slip particles further enhances the operating feel and safety of the knob 22. The anti-slip particles increase the friction on the surface of the knob 22, so that when the user rotates the knob 22, the fingers are not easy to slip. Even in wet or sweaty conditions, the rotation force and speed of the fixed rod 20 can be accurately and stably controlled, thereby accurately adjusting the position of the slider 15 to achieve a firm fixation or flexible folding of the support plate 9 and the learning machine body 1.
[0034] like Figure 4 and Figure 5 As shown, the diameters of the rotating block 12, the inserting rod 11, the connecting column 18, the threaded rod 17 and the fixing rod 20 decrease in sequence.
[0035] Specifically, since the diameter of the insertion rod 11 is smaller than that of the rotating block 12, the rotating block 12 cannot be separated from the rotating groove 13, thereby fixing the limit block 10; since the diameter of the connecting column 18 is larger than the fixing rod 20, the connecting column 18 cannot slide, thereby ensuring that the threaded rod 17 will not move.
[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the bottom of the mounting plate 2 is fixedly connected with an arc-shaped card plate 23, and one end of the arc-shaped card plate 23 is in contact with the lower part of the learning machine body 1. The top of the mounting plate 2 is fixedly connected with two symmetrically arranged buckles 24, the buckles 24 correspond to the positions of the learning machine body 1, and the outer wall of the buckles 24 is fixedly connected with a connecting plate 25.
[0037] Specifically, the use of the arc-shaped card plate 23 and the buckle 24 can improve the stability of the learning machine body 1. When installing the learning machine body 1, the user first inserts the lower part of the learning machine body 1 into the arc-shaped card plate 23, and then squeezes the upper part of the learning machine body 1 to deform the buckle 24, and then the upper part of the learning machine body 1 is snapped into the buckle 24, and then the magnetic sheet 3 and the circular magnet 4 are adsorbed to fix the learning machine body 1, forming a double guarantee to ensure the stable installation and safe use of the learning machine body 1 on the bracket; when the user needs to remove the learning machine body 1, the connecting plate 25 can be pried up with the fingers, and the connecting plate 25 will drive the buckle 24 to separate from the learning machine body 1, thereby canceling the fixation of the top of the learning machine body 1, and the user can then remove the learning machine body 1.
[0038] like Figure 2 , Figure 7 and Figure 8 As shown, an elastic layer 26 is fixedly connected to the surface of the mounting plate 2 .
[0039] Specifically, the elastic layer 26 can provide protection for the back of the learning machine body 1 to prevent scratches on the back of the learning machine body 1, and can also play a role in buffering and shock absorption. When the learning machine body 1 is installed or disassembled, it can reduce the wear caused by hard contact and extend the service life of the learning machine body 1. At the same time, when the learning machine body 1 is fixed on the mounting plate 2, the elastic layer 26 can also fill the gap between the mounting plate 2 and the learning machine body 1, enhance the fit and stability between the two, and make the learning machine body 1 more stable on the bracket and not easy to shift or fall due to slight bumps or tilts.
[0040] like Figure 6 As shown, a plurality of foot pads 27 are fixedly connected to one side of the support plate 9 .
[0041] Specifically, the foot pad 27 can increase the friction between the support plate 9 and the table top, improve the stability of the support plate 9, and at the same time improve the supporting ability of the support plate 9 on an uneven table top, thereby improving the applicability and practicality of the support plate 9. The foot pad 27 can also play a buffering role, reducing the noise generated by the direct contact between the support plate 9 and the table top, and reducing possible scratches on the table top material.
[0042] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
