[0039] To address the inconvenience of dust prevention operation in existing training devices, and the problem that grooves on the upper surface of the training platform hinder normal use, this invention provides a training device comprising: a training platform 1, with a recessed storage groove 5 on its upper surface; a training panel 2, mounted on the training platform 1, with the lower end of the operating surface 21 of the training panel 2 near one side of the storage groove 5; and a dustproof plate 4, the lower end of which rotates with the training platform 1. The connection includes a dustproof plate 4 that can block the operating surface 21, or a dustproof plate 4 located in a storage slot 5 with its upper surface flush with the upper surface of the training platform 1; and a filling plate 6, which is vertically and vertically positioned in the storage slot 5 and configured such that: when the dustproof plate 4 is not in the storage slot 5, the filling plate 6 rises so that its upper surface is flush with the upper surface of the training platform 1; when the dustproof plate 4 is in the storage slot 5, the filling plate 6 descends to provide space for the storage slot 5 to accommodate the dustproof plate 4, so that the upper surface of the dustproof plate 4 is flush with the upper surface of the training platform 1.

[0040] like Figure 1 As shown, when the training device is idle, the dustproof plate 4 can be rotated to cover the operating surface 21, blocking the operating buttons and other components on the operating surface 21, thus achieving dust prevention. The rotation operation is simple and convenient. Furthermore, the upper surface of the training platform 1 remains flat both when the training device is idle and when in use. When the training device is not in use, as... Figure 1 As shown, the filling plate 6 in the storage slot 5 rises to be flush with the upper surface of the training platform 1. This allows for easy cleaning of dust accumulated on the upper surface of the training platform 1 due to prolonged disuse, avoiding the problem of dust settling and becoming difficult to clean in recessed areas. When the training device is in use, as... Figure 2 As shown, rotate the dustproof plate 4 so that it is accommodated in the storage slot 5. At this time, the filling plate 6 descends to provide space for the storage slot 5 to accommodate the dustproof plate 4. After the dustproof plate 4 enters the storage slot 5, the upper surface of the dustproof plate 4 is flush with the upper surface of the training platform 1, and can be used as a desktop normally, avoiding the upper surface of the training platform 1 from being concave or convex and affecting normal use.

[0041] In some embodiments, the dustproof plate 4 is configured to conform to the shape of the operating surface 21, such as... Figure 1 The upper end of the operating surface 21 is inclined, and the lower end is perpendicular to the training platform 1. The lower end of the dustproof plate 4 is bent to conform to the shape of the operating surface 21. Figure 2 As shown, when the dustproof plate 4 is rotated into the storage slot 5, the bent part of the dustproof plate 4 protrudes from the upper surface of the training platform 1. The protruding part is very small and does not affect the use of the training platform 1 as a desktop. The rest of the part is stored in the storage slot 5, and the upper surface is flush with the upper surface of the training platform 1.

[0042] In some embodiments, the lower end of the dustproof plate 4 is connected with a rotating shaft 7 on both sides of the length direction, and the rotating shaft sleeve 8 is correspondingly arranged on the practical training platform 1 outside the rotating shaft 7, and the rotating shaft 7 is rotatably connected with the rotating shaft sleeve 8, so as to realize the rotation of the dustproof plate 4. When the rotating shaft 7 rotates in the rotating shaft sleeve 8, the dustproof plate 4 is rotatably connected with the practical training platform 1, and the dustproof plate 4 can be rotated to the operation surface 21 and the storage groove 5. In order to realize the rotation of the dustproof plate 4 when the lower end of the dustproof plate 4 is bent, the rotating shaft sleeve 8 and the rotating shaft 7 are partially arranged above the practical training platform 1 and partially arranged in the practical training platform 1, and the positions of the rotating shaft sleeve 8 and the rotating shaft 7 can be adjusted according to the actual situation, as shown in Figure 1 The structure of the rotating connection is not limited to this, and the rotating shaft can also be arranged to extend to the practical training platform 1 through the lower end of the dustproof plate 4, and the rotating shaft is rotatably connected with the dustproof plate 4 inside, and any structure that can realize the rotating connection between the dustproof plate 4 and the practical training platform 1 can be used.

[0043] In some embodiments, the side surface of the practical training panel 2 adjacent to the operation surface 21 is provided with a first fixing device, and the first fixing device can fix the dustproof plate 4 on the operation surface 21, so that the dustproof plate 4 covers the operation surface 21 to prevent dust when the practical training device is idle.

[0044] In some embodiments, the first fixing device includes a connecting shaft 9 arranged on the side surface of the practical training panel 2 adjacent to the operation surface 21 and a blocking strip 10 rotatably connected with the connecting shaft 9, and the blocking strip 10 can stop the dustproof plate 4 on the operation surface 21 or release the dustproof plate 4 from the operation surface 21 by rotating. As shown in Figure 1 The connecting shaft 9 is arranged on the top surface of the practical training panel 2, the connecting shaft 9 is bent towards the operation surface 21, and the connecting shaft 9 extends out of the operation surface 21, the blocking strip 10 is arranged in the shape of a long rectangle, the connecting shaft 9 is arranged at the end of the blocking strip 10, and the diameter of the part of the connecting shaft 9 protruding outside the blocking strip 10 is greater than the diameter of the other part of the connecting shaft 9. The distance between the connecting shaft 9 and the long side of the blocking strip 10 on the blocking strip 10 is less than the distance between the connecting shaft 9 and the upper edge of the dustproof plate 4, and the distance between the connecting shaft 9 and the short side of the blocking strip 10 on the blocking strip 10 is greater than the distance between the connecting shaft 9 and the upper edge of the dustproof plate 4. When the dustproof plate 4 covers the surface of the operation surface 21, the short side of the blocking strip 10 is rotated to the upper edge of the dustproof plate 4, and the dustproof plate 4 is stopped on the operation surface 21; when the short side of the blocking strip 10 is not on the upper edge of the dustproof plate 4, the dustproof plate 4 is released from the operation surface 21. The structure of the first fixing device is not limited to this, and any structure that can realize the stopping of the dustproof plate 4 on the operation surface 21 or the release of the dustproof plate 4 from the operation surface 21 can be used.

[0045] In some embodiments, Figure 1The upper edge of the dustproof plate 4 is also provided with a protruding limiting strip handle 41. When the short edge of the blocking strip 10 is rotated onto the limiting strip handle 41, the dustproof plate 4 is stopped on the operation surface 21. Meanwhile, a strip handle embedding groove 51 for accommodating the limiting strip handle 41 is also provided in the accommodating groove 5. The limiting strip handle 41 facilitates the blocking strip 10 and the connecting shaft 9 to stop the dustproof plate 4 on the operation surface 21. Alternatively, the limiting strip handle 41 can be omitted, and the dustproof plate 4 can be directly stopped on the upper edge of the dustproof plate 4 to be fixed on the operation surface 21.

[0046] In some embodiments, a finger groove 52 is provided on any side edge of the accommodating groove 5 that is not close to the practical training panel 2. As shown in Figure 1 the finger groove 52 is formed by outwardly recessing the side edge of the accommodating groove 5 away from the practical training panel. The finger groove 52 can more conveniently rotate the dustproof plate 4 out of the accommodating groove 5. The finger groove 52 can also be provided on the other two side edges of the accommodating groove 5.

[0047] In some embodiments, a telescopic device is provided below the filling plate 6. When the dustproof plate 4 is located in the accommodating groove 5, the telescopic device drives the filling plate 6 to descend so that the upper surface of the dustproof plate 4 is flush with the upper surface of the practical training platform 1. When the dustproof plate 4 is not in the accommodating groove 5, the telescopic device drives the filling plate 6 to ascend so that the upper surface of the filling plate 6 is flush with the upper surface of the practical training platform 1.

[0048] In some embodiments, as shown in Figure 3 the telescopic device includes a pushing column 61, the upper end of the pushing column 61 being connected with the bottom surface of the filling plate 6; a wedge block 11, the wedge block 11 being provided with an inclined surface, the lower end of the pushing column 61 being in sliding cooperation with the inclined surface; and a driving mechanism, the driving mechanism being configured to drive the wedge block 11 to move in the horizontal direction, so that the pushing column 61 slides along the inclined surface of the wedge block 11 to lift and lower the filling plate 6. When the practical training device is idle, as shown in Figure 3 the driving mechanism drives the wedge block 11 to move towards the pushing column 61, and the pushing column 61 slides along the inclined surface of the wedge block 11 to ascend, thereby lifting the filling plate 6 at the upper end of the pushing column 61, so that the filling plate 6 is lifted to be flush with the practical training platform 1. When the practical training device is in use, as shown in Figure 4As shown, the driving mechanism drives the wedge 11 to move in the direction away from the push column 61, the push column 61 slides down along the inclined surface of the wedge 11 due to its own gravity and the pressure of the filling plate 6, and drives the filling plate 6 at the upper end to descend, thereby providing space for the dustproof plate 4 to be accommodated in the receiving groove 5, rotating the dustproof plate 4 into the receiving groove 5, and lowering the filling plate 6 to the upper surface of the dustproof plate 4 to be flush with the upper surface of the practical training platform 1. The structure of the telescopic device is not limited to this, and any structure that can realize the telescopic movement of the filling plate 6 can be used. A spring and a moving block can also be sequentially arranged below the filling plate 6, the moving block is further connected to the lower surface of the practical training platform 1, and the filling plate 6 is raised and lowered through the telescopic movement of the spring, so that the upper surface of the filling plate 6 is flush with the upper surface of the practical training platform 1 or the upper surface of the dustproof plate 4 is parallel to the upper surface of the practical training platform 1. A cylinder can also be arranged on the bottom surface of the practical training platform 1, and the output end of the cylinder is connected to the bottom of the filling plate 6 to drive the filling plate 6 to rise or descend.

[0049] In some embodiments, limit components are arranged at both ends of the inclined surface respectively to prevent the push column 61 from sliding out of the inclined surface when the push column 61 slides along the inclined surface of the wedge 11. As shown, Figure 3 As shown, protrusions 17 are arranged at both ends of the inclined surface to block the further sliding of the push column 61, and the sliding range of the push column 61 is limited on the inclined surface. Other structures of limit components can also be used, which are not limited to this.

[0050] In some embodiments, as shown, Figure 3 The driving mechanism includes a spring 13 arranged in the horizontal direction, one end of the spring 13 is connected to the wedge 11, and the other end is connected to the practical training platform 1. The spring 13 provides elastic force for the horizontal reciprocating movement of the wedge 11. If the spring 13 is installed in a compressed state, the spring 13 drives the wedge 11 to translate in the direction close to the push column 61; if the spring 13 is installed in a stretched state, the spring 13 drives the wedge 11 to translate in the direction away from the push column 61. The distance of the translation of the wedge 11 driven by the spring 13 can be controlled to make the filling plate 6 rise and descend, so that the height of the filling plate 6 reaches the height at which the upper surface of the filling plate 6 is flush with the upper surface of the practical training platform 1; or the filling plate 6 descends to provide space for the dustproof plate 4 to be accommodated in the receiving groove 5, and the upper surface of the dustproof plate 4 is flush with the upper surface of the practical training platform 1. The driving mechanism can also be a cylinder, the output end of the cylinder is connected to the wedge 11, and the wedge 11 reciprocates in the horizontal direction, and the distance of the reciprocating movement of the wedge 11 in the horizontal direction is controlled to realize the rising and descending of the filling plate 6.

[0051] In some embodiments, as shown, Figure 3As shown, the driving mechanism comprises a guide slide shaft 12, which is arranged inside the spring 13 to provide guidance for the extension direction of the spring 13. The guide slide shaft 12 is movably sleeved inside the wedge block 11 at the end connected with the spring 13. The wedge block 11 is provided with an opening in the horizontal direction at the end connected with the spring 13, and the end of the guide slide shaft 12 is arranged in the opening and can slide in the horizontal direction in the opening. When the spring 13 drives the wedge block 11 to reciprocate, the wedge block 11 reciprocates along the guide slide shaft 12. As shown Figure 3 As shown, the other end of the guide slide shaft 12 is bent upward and connected with the bottom surface of the practical training platform 1, thereby providing support for the spring 13 and the wedge block 11. Figure 3 In some embodiments, a support plate 16 is further arranged between the end of the spring 13 away from the wedge block 11 and the bent part of the guide slide shaft 12, thereby further providing stable support for the extension of the spring 13.

[0052] In some embodiments, a second fixing device 53 is arranged on the practical training platform 1, which is used to fix the position of the dustproof plate 4 when the upper surface of the dustproof plate 4 is flush with the upper surface of the practical training platform 1, and is used to fix the position of the filler plate 6 when the upper surface of the filler plate 6 is flush with the upper surface of the practical training platform 1. As shown Figure 1As shown, when the spring 13 is installed in a compressed state, the second fixing device 53 is arranged as an oblong strip, arranged at one end of the receiving groove 5 away from the operation surface 21 and rotationally connected with the practical training platform 1. The strip can be fixed on the practical training platform 1 by using a nail of the prior art to pass through the strip and the upper surface of the practical training platform 1, the part of the nail in the strip is arranged as a smooth rod, and the part of the nail in the practical training platform 1 is provided with a thread, so as to realize the rotation of the strip on the practical training platform 1 around the smooth rod of the nail. The distance from the nail to the short side of the strip is greater than the distance from the nail to the edge of the receiving groove 5, and the distance from the nail to the long side of the strip is less than the distance from the nail to the edge of the receiving groove 5. Rotating the strip to cover the short side of the strip on the dustproof plate 4 or the filler plate 6 can fix the position of the dustproof plate 4 or the filler plate 6; rotating the strip to make the short side of the strip not on the dustproof plate 4 or the filler plate 6 can release the dustproof plate 4 or the filler plate 6. When the spring 13 is installed in a stretched state, the edge of the receiving groove 5 away from the operation surface 21 is outwardly recessed to form a recess, and the second fixing device 53 is arranged in the recess. The second fixing device 53 can be arranged as an L-shaped structure, including a vertical rotating shaft and a blocking piece integrally formed at the bottom. The rotating shaft is fixed in the recess by the same nail as described above and can rotate around the nail. Rotating the rotating shaft can rotate the blocking piece to below the filler plate 6 or the dustproof plate 4 to fix the position of the dustproof plate 4 or the filler plate 6; rotating the rotating shaft to make the blocking piece away from below the dustproof plate 4 or the filler plate 6 can make the dustproof plate 4 and the filler plate 6 normally lift and fall. If the dustproof plate 4 and the filler plate 6 have the same thickness, one second fixing device 53 can be arranged to fix the positions of the dustproof plate 4 and the filler plate 6 at the same time. If the dustproof plate 4 and the filler plate 6 have different thicknesses, two second fixing devices 53 with different heights can be arranged for the dustproof plate 4 and the filler plate 6. The arrangement of the second fixing device 53 is not limited to this, and any structure that can realize the function thereof can be used. The second fixing device can also be arranged in the finger groove 52 to reduce the area of the protruding and recessed parts on the upper surface of the practical training platform 1.

When the wedge block 11 moves, the function switching plate 14 can be synchronously moved to control the opening and closing of the heat dissipation holes on the control box 3. Figure 3 and Figure 4 As shown, the control box 3 is provided with a sliding rod, the sliding rod passes through the function switching plate 14 to fix the function switching plate 14 on the control box 3. The function switching plate 14 is provided with a plurality of ventilation holes, and the control box 3 is also provided with heat dissipation holes on the contact surface of the function switching plate 14. The function switching plate 14 slides along the sliding rod to control the opening and closing of the heat dissipation holes.
