[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1: A language learning children's teaching aid, such as Figure 1 and Figure 2 , including a base 1, which can be placed on a desktop or on the floor, which is convenient for users to place. A driving rod 11 is provided on the base 1, and a fixing plate 12 for fixing the learning machine 2 is provided on the driving rod 11. At this time, there are many ways for the fixing plate 12 to fix the learning machine 2, which are not limited here. An adjusting member for adjusting the angle of the fixing plate 12 is provided on the driving rod 11.

[0030] like Figure 1 and Figure 2 , fix the learning machine 2 on the fixed plate 12, and then adjust the angle between the driving rod 11 and the fixed plate 12 through the adjusting piece, so as to facilitate the adjustment of the angle of the learning machine 2, which is convenient for children to learn. In addition, the setting of the driving rod 11 increases the height of the learning machine 2, which facilitates the rotation of the fixed plate 12.

[0031] like Figure 2 and Figure 3 The adjusting member includes a first turntable 13 fixedly arranged at one end of the driving rod 11 away from the fixed plate 12, a vertical rod 131 is fixedly arranged on the base 1, a second turntable 132 is fixedly arranged on the upper end of the vertical rod 131, the second turntable 132 is arranged opposite to the first turntable 13, and the second turntable 132 is coaxially distributed with the first turntable 13, a cavity 133 is arranged in the second turntable 132, and a compression spring 134 and an annular fixing ring 135 are respectively arranged on the inner cavity wall opposite to the second turntable 132, the center of the fixing ring 135 is located on the central axis of the second turntable 132, and the fixing ring 135 is close to the second turntable 132. The first rotating disk 13 is distributed near the first rotating disk 13, and a disc-shaped moving plate 136 is placed between the compression spring 134 and the fixed ring 135 in the cavity 133 of the second rotating disk 132. One end of the compression spring 134 away from the inner cavity wall of the second rotating disk 132 abuts against one side of the moving plate 136. The moving plate 136 is provided with a penetration rod 137 that penetrates the disk surface of the second rotating disk 132 on the side facing the fixed ring 135. The penetration rod 137 is fixed on the disk surface of the first rotating disk 13 at the penetration end. At this time, the axis of the penetration rod 137 is located on the same axis as the axes of the second rotating disk 132 and the first rotating disk 13. Figure 3 and Figure 4 , the side surfaces facing each other of the movable plate 136 and the fixed ring 135 are provided with a plurality of driving teeth 138 distributed along a ring. At this time, the center of the ring of the driving teeth 138 distributed along the ring is located on the same straight line as the center of the second turntable 132, and the driving teeth 138 on the movable plate 136 are embedded between two adjacent driving teeth 138 on the fixed ring 135. When the compression spring 134 is in a natural state, the driving teeth 138 on the movable plate 136 are embedded between two adjacent driving teeth 138 on the fixed ring 135 and there is a gap between the first turntable 13 and the second turntable 132.

[0032] like Figure 3 and Figure 4When the compression spring 134 is in a natural state, the driving teeth 138 on the movable plate 136 are embedded between two adjacent driving teeth 138 on the fixed ring 135. At this time, the relative rotation between the movable plate 136 and the fixed ring 135 is restricted, and the compression spring 134 squeezes the movable plate 136 on the fixed ring 135, and then the rotation of the first rotating disk 13 is also restricted through the penetration rod 137, so that the position of the driving rod 11 fixed to the first rotating disk 13 is also restricted. When the driving rod 11 needs to be rotated, the first rotating disk 13 is pushed toward the second rotating disk 132. At this time, the penetration rod 137 moves in the second rotating disk 132, so that the penetration rod 137 drives the movable plate 136 to squeeze the compression spring 134 in the direction away from the fixed ring 135, so that the compression spring 134 is squeezed and has an elastic restoring force. , until the first turntable 13 and the second turntable 132 are in contact with each other, at which time the driving teeth 138 on the moving plate 136 and the fixing ring 135 are separated from each other, so that the user can rotate the first turntable 13, thereby changing the angle of the driving rod 11, and thus changing the angle of the learning machine 2; when adjusting the learning machine 2 to a suitable position, the user releases the thrust of the first turntable 13 toward the second turntable 132, so that the moving plate 136 moves toward the fixing ring 135 under the elastic restoring force of the compression spring 134, until the driving teeth 138 on the moving plate 136 are embedded between two adjacent driving teeth 138 on the fixing ring 135, and then once again restricting the position of the moving plate 136, so that the position of the driving rod 11 is also restricted, which is convenient for limiting the position of the learning machine 2 and for children to watch the learning machine 2. The driving rod 11 can be fixed on the fixing plate 12 vertically to the surface of the fixing plate 12.

[0033] like Figure 1 and Figure 2 , the second rotating disk 132 is provided with a plurality of scale lines 15 on the disk surface facing the first rotating disk 13, and each scale line 15 is evenly distributed around the outer wall of the first rotating disk 13, and an indication line 151 aligned with one of the scale lines 15 is provided on the side wall of the first rotating disk 13, and when the indication line 151 is aligned with the scale line 15, the driving teeth 138 on the movable plate 136 are directly opposite to the space between two adjacent driving teeth 138 on the fixed ring 135. The purpose of this design is to facilitate the user to adjust the angular position of the learning machine 2 according to the alignment position of the indication line 151 and the scale line 15 when rotating the first rotating disk 13, so that the user can loosen the first rotating disk 13, so that when the first rotating disk 13 is separated from the second rotating disk 132, the driving teeth 138 on the movable plate 136 can mesh with the driving teeth 138 on the fixed ring 135, thereby limiting the rotation of the movable plate 136, limiting the rotation of the driving rod 11, and limiting the angular rotation of the learning machine 2.

[0034] like Figure 3In order to make the penetration rod 137 and the first turntable 13 detachably connected, an entry hole 14 is provided on the surface of the first turntable 13 for one end of the penetration rod 137 to enter, and a prism 141 is coaxially provided at one end of the penetration rod 137 located in the entry hole 14. A first hole 142 is provided on the first turntable 13 for the prism 141 to pass through, and the first hole 142 is connected to the entry hole 14. A second hole 143 connected to the first hole 142 is provided on the end of the first turntable 13 away from the entry hole 14, and the second hole 143 extends from a side of the first turntable 13 away from the second turntable 132, and the second hole 143 is a circular hole and is penetrated by a fixing block 144, and a threaded rod 145 is provided on the side of the fixing block 144 facing the prism 141 for entering the end face of the prism 141, and the threaded rod 145 is threadedly connected to the end face of the prism 141.

[0035] like Figure 3 When the first turntable 13 needs to be installed on the penetration rod 137, the first turntable 13 is sleeved on the penetration rod 137 and the outer wall of the prism 141 through the entry hole 14 and the first hole 142. The setting of the prism 141 facilitates the penetration rod 137 to rotate along with the rotation of the first turntable 13. Then, the fixing block 144 is placed in the second hole 143 and the second rod is rotated so that the threaded rod 145 on the second rod is screwed into the prism 141. At this time, one side of the second rod is in conflict with one side of the prism 141.

[0036] like Figure 3 The end surface of the fixing block 144 away from the threaded rod 145 is provided with a cross-shaped driving groove for the screwdriver to rotate, so that the user can rotate the fixing block 144 by the screwdriver.

[0037] Embodiment 2: A language learning children's teaching aid, which is different from Embodiment 1 in that Figure 5 and Figure 6 The base 1 is provided with an inwardly recessed fixing groove 16, and a rotating rod 161 is rotatably connected to the bottom of the fixing groove 16. A threaded hole 162 is provided at the lower end of the driving rod 11 for the upper end of the rotating rod 161 to be screwed in. The adjusting member includes a guide plate 163 sleeved on the outer wall of the driving rod 11, and the end of the guide plate 163 away from the driving rod 11 is fixedly connected to the groove wall of the fixing groove 16. The driving rod 11 is a rectangular rod, and the fixing plate 12 is rectangular. At this time, the guide plate 163 limits the driving rod 11 from rotating together with the rotating rod 161, and any one of the four sides of the fixing plate 12 is hinged to the upper end surface of the base 1 through a hinge, and the upper end of the driving rod 11 is in conflict with the lower end surface of the fixing plate 12. A power member for driving the rotating rod 161 to rotate is provided on the base 1.

[0038] like Figure 5 and Figure 6The hinged member includes an adjustment block 164 arranged on the upper end surface of the base 1 and located on one side of the four sides of the fixed plate 12. Each adjustment block 164 is threadedly connected with an adjustment rod 165. Both ends of the adjustment rod 165 pass through the two side surfaces of the adjustment block 164. A horizontal plate 166 and a placement plate 167 are fixedly arranged in sequence between the adjustment block 164 and the fixed plate 12 on the upper end surface of the base 1. The horizontal plate 166 is distributed close to the adjustment block 164. The four sides of the fixed plate 12 are provided with a cylindrical rod 168 embedded in the upper end surface of the placement plate 167. Both ends of the cylindrical rod 168 are provided with a horizontal rod connected to the side of the fixed plate 12, so that the cylindrical rod 168 There is a gap between the side of the fixed plate 12, the length direction of the cylindrical rod 168 is parallel to the side of the fixed plate 12, and the upper end surface of the placing plate 167 is provided with an arc groove 169 for the cylindrical rod 168 to be embedded. When the cylindrical rod 168 is embedded in the arc groove 169, the upper end side wall of the cylindrical rod 168 extends out of the notch of the arc groove 169, that is, most of the cylindrical surface of the cylindrical rod 168 enters the arc groove 169, and one end of the adjusting rod 165 is rotatably provided with a pressure plate 17 that moves back and forth in the horizontal plate 166. The adjusting rod 165 is rotated so that one end of the pressure plate 17 is located above the cylindrical rod 168 and contacts the cylindrical surface of the cylindrical rod 168.

[0039] like Figure 5 and Figure 6 The cylindrical surface of the cylindrical rod 168 is provided with an annular rotation groove 171 on the outer wall in contact with the pressure plate 17. The rotation groove 171 is coaxially distributed with the cylindrical rod 168 and a slider is provided on the pressure plate 17 to slide in the rotation groove 171.

[0040] like Figure 5 and Figure 6 At this time, the power member drives the rotating rod 161 to rotate, so that the rotating rod 161 drives the driving rod 11 to move up and down. When the driving rod 11 moves up and down, the upper end of the driving rod 11 provides a supporting force and an upward extrusion force to the fixed plate 12. At the same time, the user rotates any one of the four adjusting rods 165, so that the adjusting rod 165 drives the pressing plate 17 to gradually move toward the arc groove 169 until it moves above the cylindrical rod 168, so that the slider slides into the rotating groove 171. At this time, the pressing plate 17 restricts the cylindrical rod 168 from moving out of the arc groove 169. As the driving rod 11 gradually moves the fixed plate 12 is pushed upward, and the other three pressure plates 17 do not interfere with the corresponding cylindrical rods 168, so that the pressure plate 17 on the only rotating adjusting rod 165 interferes with the cylindrical rod 168, and then the fixed plate 12 rotates around the cylindrical rod 168, so that the fixed plate 12 flips upward, changes the angle of the learning machine 2 on the fixed plate 12, stops the rotation of the rotating rod 161 by the driving part, and limits the rotation position of the fixed plate 12, thereby fixing the position of the learning machine 2; the user can rotate the adjusting rod 165 close to him as needed, so that the fixed plate 12 rotates around this direction, which is convenient for children to use.

[0041] like Figure 5 and Figure 6 The power member includes a first bevel gear 172 coaxially fixed on the rotating rod 161, and a driving shaft 173 is rotatably connected to the base 1. One end of the driving shaft 173 is provided with a second bevel gear 174 meshing with the first bevel gear 172, and the other end extends out of the outer wall of the base 1 and is provided with a hand wheel 175 at the extended end. At this time, the user can drive the rotating rod 161 to rotate through the hand wheel 175, so that the rotating rod 161 is driven to rotate through the meshing of the second bevel gear 174 and the first bevel gear 172, thereby driving the driving rod 11 to move up and down.

[0042] like Figure 5 and Figure 6 In addition, the base 1 is rotatably connected with a first rod 18, one end of which is provided with a third bevel gear 181 meshing with the first bevel gear 172, and the other end of which extends out of the outer wall of the base 1 and is coaxially driven by a motor 182 fixed to the outer wall of the base 1, and the third bevel gear 181 and the second bevel gear 174 are distributed above the first bevel gear 172 at 180 degrees. The user can also rotate the rotating rod 161 without using the hand wheel 175, so that the motor 182 drives the rotating rod 161 to rotate. When the motor 182 is out of power, it can be driven to rotate by the hand wheel 175, which is convenient to use.

[0043] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
