[0036] The present invention will be further described below with reference to the accompanying drawings:

[0037] like Figure 1 As shown, the balance board 1 includes a balance board and an auxiliary structure 3. The auxiliary structure 3 is arranged on both sides of the balance board 1. When in use, the auxiliary structure 3 is unfolded to form a horizontal railing. When a child passes through the balance board 1, the railing needs to be climbed over, which increases the difficulty of the child's balance training. The auxiliary structure 3 is folded to retract the railing.

[0038] like Figure 1 、 Figure 3 and Figure 4 As shown, a protective pad is provided on the top of the balance board 1. The anti-slip pad 2 increases the friction between the child's feet and the balance board 1 to prevent the child from slipping off the balance board 1. Sliding grooves 101 are provided on both sides of the balance board 1, and multiple key grooves 102 are provided on the outer sides of the sliding grooves 101. The sliding grooves 101 are used to connect to the support assembly 301, and the key grooves 102 are used to limit the support assembly 301.

[0039] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the auxiliary structure 3 includes a support assembly 301, a connecting member 302, a first connecting rod 303, a spring 304 and a second connecting rod 305;

[0040] The support assembly 301 includes a support rod 3011, a support block 3012, a guide block 3013 and a circular block 3014. One end of the circular block 3014 is rotatably connected to the support rod 3011. The diameter of the circular block 3014 is the same as the inner diameter of the sliding groove 101. The circular block 3014 can slide along the sliding groove 101. The cross-sectional diameter of the support rod 3011 is the same as the outer diameter of the sliding groove 101. The support rod 3011 can slide along the sliding groove 101. The support rod 3011 will not fall out of the sliding groove 101 due to the restriction of the circular block 3014. One side of the outer wall of the support rod 3011 is fixedly connected to the support block 3012. The size of the support block 3012 is the same as the size of the key groove 102. The support block 3012 can slide inside the key groove 102. When the support block 3012 matches the horizontal key groove 102, the support rod 3011 is perpendicular to the balance board 1. When the longitudinal key slot 102 matches, the support rod 3011 and the balance board 1 are parallel to each other, a guide slot 3015 is provided in the middle of the support rod 3011, and a rectangular hole 3016 is processed at the end of the support rod 3011, the center of the rectangular hole 3016 is in the same straight line as the axis of the guide slot 3015, one side of the guide block 3013 matches the guide slot 3015, and the other side of the guide block 3013 matches the rectangular hole 3016. When the guide block 3013 slides inside the guide slot 3015, it is restricted by the rectangular hole 3016 to prevent the guide block 3013 from disengaging from the guide slot 3015. The two ends of the spring 304 are fixedly connected to the spring 304 and the sliding slot 101 respectively, and the elastic force of the spring 304 is used to prevent the circular block 3014 from moving. The distance between the support block 3012 and the circular block 3014 can ensure that the support rod 3011 can move along the circular block 3014 when the support block 3012 disengages from the key slot 102;

[0041] Specifically, a person moves the support rod 3011 outward, and the support rod 3011 drives the circular block 3014 and the support block 3012 to move. The circular block 3014 drives the spring 304 to stretch. When the support block 3012 is disengaged from the key slot 102 at the corresponding position, the support rod 3011 is rotated. When the support rod 3011 rotates along the circular block 3014 to be parallel or perpendicular to the balance board 1, the support rod 3011 is released, so that the support rod 3011 is driven by the elastic force of the spring 304 to drive the support block 3012 to cooperate with the key slot 102 at another position. The elastic force of the spring 304 ensures that the support block 3012 is always cooperated with the key slot 102, thereby limiting the rotation of the support rod 3011.

[0042] The front guide block 3013 is hinged to the second connecting rod 305, and the rear guide block 3013 is hinged to the first connecting rod 303. The second connecting rod 305 and the first connecting rod 303 can rotate along the corresponding guide block 3013 to ensure that the first connecting rod 303 and the second connecting rod 305 can be perpendicular to the support rod 3011. The end of the first connecting rod 303 is processed with a first connecting hole 3031, and the end of the second connecting rod 305 is processed with a second connecting hole 3051. The second connecting hole 3051 is a stepped hole, wherein the smaller hole of the stepped hole is the same size as the first connecting hole 3031, and the smaller hole of the second connecting hole 3051 is processed with the inner wall of the first connecting hole 3031. It has threads, the second connecting hole 3051 matches one side of the connecting piece 302, the first connecting hole 3031 matches the other side of the connecting piece 302, the connecting piece 302 is threadedly connected to the first connecting rod 303 and the second connecting rod 305, and a connecting groove 3021 is provided at the end of the connecting piece 302. The connecting groove 3021 is hexagonal, which is convenient for personnel to use a hexagonal wrench of corresponding size to rotate the connecting piece 302. The length of the connecting piece 302 is smaller than the size of the rectangular hole 3016, and the sizes of the first connecting rod 303 and the second connecting rod 305 are the same as the sizes of the rectangular hole 3016, ensuring that the first connecting rod 303 and the second connecting rod 305 can slide into the corresponding guide groove 3015 for easy recovery.

[0043] Working principle:

[0044] In front of the single-plank bridge teaching aid, the coach moves the support rod 3011 outward, and the support rod 3011 drives the circular block 3014 and the support block 3012 to move, and the circular block 3014 drives the spring 304 to stretch. When the support block 3012 is disengaged from the key slot 102 at the corresponding position, the support rod 3011 is rotated, and the support rod 3011 rotates along the circular block 3014 to be perpendicular to the balance board 1, and the support rod 3011 is loosened, so that the support rod 3011 is driven by the elastic force of the spring 304 to drive the support block 3012 to cooperate with the key slot 102 at other positions, and the spring 30 The elastic force of 4 makes the support block 3012 always cooperate with the key slot 102, thereby limiting the rotation of the support rod 3011. Then, the first connecting rod 303 and the second connecting rod 305 are pulled out from the inside of the support rod 3011. Then, the first connecting rod 303 and the second connecting rod 305 are rotated simultaneously to be perpendicular to the support rod 3011. Then, the first connecting rod and the second connecting rod are fixed by the connecting member 302, thereby forming a horizontal railing as an obstacle. When training children's balance on the balance board 1, the children need to climb over the obstacle, which increases the difficulty of the children's balance training.

[0045] When the railing obstacle is not applicable, the coach connector 302 is disassembled to separate the first link 303 and the second link 305, and then the first link 303 and the second link 305 are recovered into the corresponding guide groove 3015. Then, the support rod 3011 is pulled in the same way to separate the support block 3012 from the key groove 102, and then the support rod 3011 is rotated to be parallel to the balance board 1 and then the support rod 3011 is released to achieve the recovery of the railing obstacle.

[0046] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
