[0021] The following will be combined with the accompanying 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 embodiments described 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 technical personnel in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0022] See also Figures 1 to 6 The utility model provides a technical solution: a support structure and an English listening trainer, including a vertical shaft 2 and a fixed sleeve 3, the bottom end of the vertical shaft 2 is fixedly connected to a turntable 4, the top surface of the turntable 4 is rotatably connected to four L-shaped connecting rods 5, the four L-shaped connecting rods 5 are rotatably connected to the first slider 6 and the second slider 7 at one end away from the turntable 4, the top edge of the first slider 6 is fixedly connected to a fixing plate 8, the middle part of the fixing plate 8 is threadedly connected to an adjusting screw 9, one side of the first slider 6 is hinged to a bracket assembly 10, and both sides of the second slider 7 are provided with a stabilizing assembly 1 1, the middle part of the fixing sleeve 3 is movably connected to the middle part of one side of the bracket assembly 10; the adjusting screw 9 is a bidirectional thread, and the two fixing plates 8 are driven to move in opposite directions by rotating the adjusting screw 9. At this time, the fixing plate 8 drives the first slider 6 to slide along the inside of the cross-shaped slide groove 12, and the first slider 6 drives the turntable 4 to rotate around the vertical axis 2 through the L-shaped connecting rod 5. At this time, the turntable 4 also drives the second slider 7 to move synchronously through the L-shaped connecting rod 5, so that the bracket assembly 10 is expanded or stored. This structure can reduce the space occupied by the hearing trainer.

[0023] In this embodiment, Figure 1 and Figure 5 As shown, the bracket assembly 10 includes an inclined link 1001 hinged on one side of the first slider 6, and a horizontal rod 1002 is hinged on the end of the inclined link 1001 away from the first slider 6. The horizontal rod 1002 is fixedly connected to the middle part of the support frame 1003, and a limiting protrusion 1004 is fixedly connected to the outer surface of one side of the support frame 1003. A through hole is opened in the middle part of the fixing sleeve 3, and a limiting groove 301 is opened on the inner wall of the through hole. The limiting protrusion 1004 is movably connected to the inside of the limiting groove 301; the support frame 1003 is a trapezoidal structure, which can enable the support frame 1003 to support the hearing trainer more stably, and the inclined link 1001 is set between the support frame 1003 and the hearing trainer body 1, and can block the support frame 1003 in the storage state to prevent the support frame 1003 from being parallel to the bottom surface of the hearing trainer body 1 and forming a dead point, which makes it impossible to open.

[0024] In this embodiment, Figure 2 and Figure 5 As shown, the stabilizing assembly 11 includes a multi-stage telescopic rod 1101 hinged on both sides of the second slider 7, and the end of the multi-stage telescopic rod 1101 away from the second slider 7 is connected to the middle of the stabilizing sleeve 1102. The outer surface of the stabilizing sleeve 1102 is provided with a plurality of anti-slip rings 1103, and the stabilizing sleeve 1102 is slidably connected to one side of the support frame 1003. The stabilizing sleeve 1102 is provided with two groups, and the anti-slip rings 1103 on the outer surface of the two groups of stabilizing sleeves 1102 are tilted in opposite directions. The two groups of anti-slip rings 1103 are symmetrically distributed about the tilting connecting rod 1001; this structure can be used to control the hearing trainer itself. While supporting the hearing trainer body 1, it can also increase the friction between the hearing trainer body 1 and the ground in the front-to-back direction, thereby preventing the hearing trainer body 1 from being displaced in the front-to-back direction due to external collisions. In the left-to-right direction, the maximum opening angle of the two support frames 1003 is limited due to the mutual cooperation between the limiting protrusion 1004 and the limiting groove 301. When the two support frames 1003 are fully unfolded, the area formed by the two support frames 1003, the hearing trainer body 1 and the ground is an isosceles trapezoid. This structure can effectively resist impact forces from the left and right directions and has high stability.

[0025] An English listening trainer includes a listening trainer body 1. The top end of a vertical axis 2 is rotatably connected to the middle portion of the bottom surface of the listening trainer body 1. A cross-shaped slide groove 12 is formed on the bottom surface of the listening trainer body 1. A first slider 6 and a second slider 7 are slidably connected within the cross-shaped slide groove 12. A fixing sleeve 3 is welded to the bottom surface of the listening trainer body 1. A support structure as described above is installed on the listening trainer body 1.

[0026] The use method and advantages of the utility model: When the support structure and the English listening trainer are in use, the working process is as follows:

[0027] Rotating the adjusting screw 9 drives the two first sliders 6 to move in opposite directions, thereby driving the turntable 4 to rotate. When the turntable 4 rotates, it can simultaneously drive the four sliders to move equidistantly. The first slider 6 drives the bracket assembly 10 to expand or fold, and the stabilizing assembly 11 can increase the stability and impact resistance of the hearing trainer body 1 in the front and back directions. When the hearing trainer body 1 is not needed, the adjusting screw 9 is rotated in the opposite direction to fold the bracket assembly 10 and the stabilizing assembly 11 and fit them to the bottom surface of the hearing trainer body 1, thereby reducing the space occupied by the hearing trainer body 1.
