[0002] As children's motor skills gradually develop, balance training has become an important part of promoting their motor coordination, enhancing physical fitness, and preventing sports injuries. Balance ability is not only the basis of basic motor skills, but also an important manifestation of brain development, body stability, posture control, and motor skills.

[0027] Reference Figure 1-Figure 7 A device for detecting balance exercises of young children comprises a base 1, two support plates 2 are symmetrically fixedly installed on the upper surface of the base 1, a rotating shaft 12 is rotatably installed between the two support plates 2, an arc seesaw 3 is fixedly installed on the outer surface of the rotating shaft 12, two supports 14 are symmetrically fixedly installed on the arc outer surface of the arc seesaw 3, a connecting rod 15 is rotatably installed between the inner walls of the two supports 14, two support blocks 28 are symmetrically fixedly installed on the upper surface of the base 1, a sliding column 19 is fixedly installed between the two support blocks 28, two sliding sleeves 16 are symmetrically slidably installed on the outer surface of the sliding column 19, the upper surfaces of the two sliding sleeves 16 are rotatably installed with the bottom ends of the two connecting rods 15 respectively, and a limited sliding rod 20 is fixedly installed between the two support blocks 28, The limiting slide bar 20 is arranged directly below the slide column 19. Two retaining rings 17 are symmetrically and slidably installed on the outer surface of the limiting slide bar 20. The slide column 19 passes through the two retaining rings 17 and is slidably installed therewith. The two retaining rings 17 are respectively arranged at one end of the two sliding sleeves 16 away from each other. The outer surface of the slide column 19 is symmetrically sleeved with two springs 18. The spring 18 is arranged between the retaining ring 17 and the sliding sleeve 16. The two ends of the retaining ring 17 are respectively fixedly connected to the outer surfaces of the retaining ring 17 and the sliding sleeve 16. The center line of the rotating shaft 12 and the center line of the slide column 19 are arranged perpendicular to each other. One end of the rotating shaft 12 passes through the outer surface of one of the support plates 2 and an indicating arrow 13 is fixedly installed thereon. A dial 22 is fixedly installed on the outer surface of the support plate 2 close to the indicating arrow 13.

[0028] When in use, the staff guides the child to put both feet on the pedals 6 and stand up straight, and then according to the child's own adjustment, the child stands firmly on the arc seesaw 3. When the arc seesaw 3 stops shaking left and right, at this time, the staff observes the position of the indicator arrow 13 on the dial 22, and uses the device to detect the child's balance before balance training and the balance after balance training. The two detection results are compared to facilitate the staff to modify the child's balance training process in time according to the comparison of the two results. If the right side of the arc seesaw 3 is higher than the left side, it means that the child's center of gravity is biased to the left. At this time, the angle between the left connecting rod 15 and the sliding column 19 is smaller than the angle between the left connecting rod 15 and the sliding column 19. The child controls the arc seesaw 3 to swing left and right by alternately pressing the left and right feet. Because the angle between the right connecting rod 15 and the sliding column 19 is large, when the child presses the right side of the arc seesaw 3, it needs more weight to press it, thereby making its center of gravity tilt more to the right. Through this device, targeted training and correction can be carried out according to the deviation of the left and right center of gravity of the child.

[0029] In this embodiment, the interior of the arc seesaw 3 is hollow, and two T-shaped grooves 5 are symmetrically provided on the upper surface of the arc seesaw 3. T-shaped sliders 7 are slidably installed on the inner walls of the two T-shaped grooves 5, and a pedal 6 is fixedly installed on the upper surface of the T-shaped slider 7. Two first mounting blocks are symmetrically fixedly installed on the top wall of the arc seesaw 3, and a bidirectional screw rod 8 is rotatably installed between the two first mounting blocks. The bidirectional screw rod 8 passes through the outer surfaces of the two T-shaped sliders 7 and is threadedly connected thereto. A worm gear 9 is fixedly installed on the outer surface of the bidirectional screw rod 8 near the middle position, and two second mounting blocks are symmetrically fixedly installed on the top wall of the arc seesaw 3. A worm 10 is rotatably installed between the two second mounting blocks, and the worm 10 is meshed with the worm gear 9. The end of the worm 10 near the indicator arrow 13 passes through the outer surface of one of the second mounting blocks and a knob 11 is fixedly installed thereon.

[0030] Before use, the staff manually turns the knob 11 according to the height and shoulder width of the child to drive the worm 10 to rotate, the worm 10 drives the worm wheel 9 to rotate, the worm wheel 9 drives the bidirectional screw 8 to rotate, and the bidirectional screw 8 drives the two pedals 6 to move closer or farther through the T-shaped slider 7. Through this device, the appropriate distance between the pedals 6 can be adjusted according to the size of the child, thereby improving the applicability of the device.

[0031] In this embodiment, a connecting rod 21 is fixedly installed between the outer surfaces of the adjacent sides of the two retaining rings 17, and a rack 23 is fixedly installed on the upper surface of the connecting rod 21 near the middle position. A transmission shaft 27 is rotatably installed on the outer surface of one of the support plates 2 near the rack 23, and a gear 26 is fixedly installed at one end of the transmission shaft 27. The gear 26 is meshed with the rack 23. The end of the transmission shaft 27 near the indicator arrow 13 passes through the outer surface of the support plate 2 and is fixedly installed with a rotating wheel 24. A clamping bolt 25 is inserted into the outer surface of the rotating wheel 24, and one end of the clamping bolt 25 passes through the outer surface of the rotating wheel 24 and is threadedly connected to it. The clamping bolt 25 is set at an eccentric position of the rotating wheel 24.

[0032] When the child is adjusting the balance by himself, the arc seesaw 3 will swing left and right. When the arc seesaw 3 swings, the sleeve 16 is driven to slide left and right along the outer surface of the slide column 19 through the support 14 and the connecting rod 15, and the retaining ring 17 is driven to move left and right under the action of the spring 18 and the connecting rod 21. When the arc seesaw 3 is stationary, the clamping bolt 25 is manually rotated to make its end abut against the outer surface of the support plate 2, and the position of the rotating wheel 24 is fixed by this device. At the same time, the rotating wheel 24 limits the position of the connecting rod 21 through the transmission shaft 27, the gear 26 and the rack 23, so that the retaining ring 17 stops at the fixed position of the limiting slide bar 20. It should be noted that at this time, the child on the arc seesaw 3 is in a self-adjusted balance state.

[0033] In this embodiment, the outer surface of the base 1 on the side of the indicating arrow 13 is symmetrically provided with two transparent cylinders 4, the outer surfaces of the two sliding sleeves 16 on the side close to the transparent cylinder 4 are fixedly installed with connecting blocks, the outer surfaces of the adjacent sides of the two connecting blocks are fixedly installed with push rods 32, and the adjacent ends of the two push rods 32 are fixedly installed with piston plates 31, and the upper surface of the base 1 is symmetrically fixedly installed with two piston cylinders 34, and the two piston plates 31 are respectively slidably installed with the inner walls of the two piston cylinders 34, and the outer surfaces of the piston cylinders 34 are provided with The water inlet pipe joint and the water outlet pipe joint are both provided with a one-way valve 33 at the end of the water inlet pipe joint and the water outlet pipe joint, one end of one of the one-way valves 33 is fixedly connected to the water inlet pipe 30, and one end of the other one-way valve 33 is fixedly connected to the water outlet pipe, the water inlet pipe 30 and the water outlet pipe both pass through the inner wall of the transparent cylinder 4, the water outlet pipe is L-shaped, the top of the water outlet pipe is fixedly connected to the nozzle 29, the nozzle 29 is connected to the inside of the piston cylinder 34 through the water outlet pipe, and the water inlet pipe 30 is connected to the inside of the piston cylinder 34 through the one-way valve 33.

[0034] The circular arc seesaw 3 is swung left and right to drive the sliding sleeve 16 to slide left and right. The sliding sleeve 16 drives the push rod 32 to move left and right through the connecting block. The push rod 32 drives the piston plate 31 to slide left and right along the inner wall of the piston cylinder 34. When the piston plate 31 slides outward, the water in the transparent cylinder 4 is pumped out by the water inlet pipe 30 through the one-way valve 33. When the piston plate 31 slides inward, the water is sprayed out from the nozzle 29 through the water outlet pipe through the one-way valve 33. The water in the transparent cylinder 4 can be sprayed out from the nozzle 29 through the device, which increases the fun of the balance training for young children. At the same time, the staff can observe in real time whether the pressure of the left and right sliding sleeves 16 on the piston plate 31 is the same according to the height of the water sprayed by the left and right nozzles 29, thereby guiding the children to adjust the left and right downward pressure in real time.

[0035] It should be noted that before the present invention is used, the staff manually rotates the knob 11 according to the height and shoulder width of the child to drive the worm 10 to rotate, the worm 10 drives the worm wheel 9 to rotate, the worm wheel 9 drives the bidirectional screw 8 to rotate, and the bidirectional screw 8 drives the two pedals 6 to move closer or farther through the T-shaped slider 7. Through this device, the appropriate distance between the pedals 6 can be adjusted according to the size of the child, thereby improving the applicability of the device; when in use, the staff guides the child to put the two feet on the upper part of the pedal 6 and stand up straight, and then according to the child's own adjustment, the child stands firmly on the arc seesaw 3. When the arc seesaw 3 stops shaking left and right, at this time, the staff observes the position of the indicator arrow 13 on the dial 22, and the device can detect whether the child's center of gravity is biased to the right or left; when the child adjusts the balance by himself, the arc seesaw 3 will swing left and right. When the arc seesaw 3 swings, the sliding sleeve 16 is driven by the support 14 and the connecting rod 15 to slide left and right along the outer surface of the sliding column 19, and the retaining ring 17 is driven to follow the left and right under the action of the spring 18 and the connecting rod 21. When the circular arc seesaw 3 is stationary, the clamping bolt 25 is manually rotated to make its end abut against the outer surface of the support plate 2, and the position of the rotating wheel 24 is fixed by this device. At the same time, the rotating wheel 24 limits the position of the connecting rod 21 through the transmission shaft 27, the gear 26 and the rack 23, so that the retaining ring 17 stops at the position fixed by the limiting slide bar 20. It should be noted that at this time, the child on the circular arc seesaw 3 is in a self-adjusted balance state; when the position of the retaining ring 17 is determined, if the right side of the circular arc seesaw 3 is higher than the left side ... the child on the circular arc seesaw 3 is in a self-adjusted balance state; when the position of the retaining ring 17 is determined, if the right side of the circular arc seesaw 3 is higher than the left side, the child on the circular arc seesaw The lower side indicates that the child's center of gravity is biased to the left. At this time, the angle between the connecting rod 15 and the sliding column 19 on the left side is smaller than the angle between the connecting rod 15 and the sliding column 19 on the oil side. The child controls the circular arc seesaw 3 to swing left and right by alternately pressing the left and right feet. Because the angle between the connecting rod 15 and the sliding column 19 on the right side is large, when the child presses the right side of the circular arc seesaw 3, a larger weight is required to press it, thereby making the child's center of gravity tilt more to the right. Through this device, targeted training and correction can be carried out according to the deviation of the child's left and right center of gravity.The circular arc seesaw 3 swings left and right to drive the sliding sleeve 16 to slide left and right. The sliding sleeve 16 drives the push rod 32 to move left and right through the connecting block. The push rod 32 drives the piston plate 31 to slide left and right along the inner wall of the piston cylinder 34. When the piston plate 31 slides outward, the water in the transparent cylinder 4 is pumped out by the water inlet pipe 30 through the action of the one-way valve 33. When the piston plate 31 slides inward, the water is sprayed out from the nozzle 29 through the water outlet pipe through the one-way valve 33. The water in the transparent cylinder 4 can be sprayed out from the nozzle 29 through the device, which increases the fun of the balance training of the children. At the same time, according to the height of the water sprayed by the left and right nozzles 29, the staff can observe in real time whether the pressure of the left and right sliding sleeves 16 on the piston plate 31 is the same, so as to guide the children to adjust the left and right downward pressure in real time. The balance of the children before the balance training and the balance of the children after the balance training are detected by the device. The two detection results are compared, which is convenient for the staff to modify the process of the children's balance training in time according to the comparison of the two results. ;

[0036] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
