[0002] Children's balance beam is a training equipment used to help children develop balance ability. Children's balance beam can be used for a variety of training purposes, including improving body coordination, strengthening core muscles, improving spatial perception, etc. By performing different movements, such as walking, running, jumping, turning, etc., children can challenge their balance limits on the balance beam and gradually increase the difficulty.

[0003] However, the existing children's balance beam has a simple structure and is usually not adjustable. It cannot be adaptively adjusted according to the needs of use. There are also certain safety risks. Children may lose balance on the balance beam, resulting in falls or injuries. Secondly, the balance beam is inconvenient to move. Based on the above problems, this application document proposes a children's physical training exercise device. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, a children's physical training and exercise device includes a base plate 10, a plurality of fixing frames 11 are fixed to the upper end of the base plate 10, the four end corners of the tops of the plurality of fixing frames 11 are rotatably connected to a first connecting rod 12, a first connecting block 13 is rotatably connected between two first connecting rods 12 located at the same end, a second connecting rod 14 is rotatably connected to the upper ends of the two first connecting blocks 13, a second connecting block 15 is rotatably connected between the plurality of second connecting rods 14, a balance board 18 is fixed to the top of the second connecting block 15, a threaded rod 16 is rotatably connected to the inside of the two first connecting blocks 13, and a hand wheel 17 is fixed to one end of the threaded rod 16.

[0027] Furthermore, the outer side of the handwheel 17 is sleeved with an anti-slip rubber sleeve, and a number of anti-slip grooves are evenly arranged on the outer side of the anti-slip rubber sleeve. The anti-slip grooves can increase the roughness of the surface of the handwheel 17, thereby increasing the friction between the hand and the handwheel 17. Secondly, the design of the anti-slip grooves can provide a better grip, so that the handwheel 17 can be held more comfortably during operation. It can also increase the wear resistance of the surface of the handwheel 17, thereby extending the service life of the handwheel 17.

[0028] Furthermore, the balance board 18 is made of a flexible material, and an outer side of the balance board 18 is provided with anti-slip grooves.

[0029] like Figure 3 and Figure 4As shown, a groove is provided at one end of the base plate 10, in which a plurality of evenly arranged first shock-absorbing springs 21 are fixed, a shock-absorbing plate 22 is fixed at the upper end of the first shock-absorbing spring 21, and the shock-absorbing plate 22 is adapted to the groove. The application of the shock-absorbing plate 22 reduces the vibration and noise generated by the device, and reduces the interference and impact on the surrounding environment. Secondly, the shock-absorbing plate 22 can protect children from jumping and getting injured.

[0030] like Figure 5 , Figure 6 and Figure 7 As shown, the four end corners of the bottom end of the base plate 10 are each provided with a receiving hole 25, the interior of the receiving hole 25 is slidably connected with a roller 23, a second shock-absorbing spring 24 is fixed inside the base plate 10 and at the upper end of the roller 23, a positioning hole 26 is provided on one side of the base plate 10, and a first through hole adapted to the positioning hole 26 is provided at the top end of the roller 23.

[0031] like Figure 3 As shown, a support plate 19 is fixed to the upper end of the bottom plate 10 and located at the bottom end of the balance plate 18 , a second through hole is opened on one side of the support plate 19 , and the threaded rod 16 passes through the second through hole.

[0032] The working principle of the utility model is:

[0033] The bottom plate 10 is fixed on the ground. When a child passes through the training and exercise device easily, the threaded rod 16 can be driven to rotate by rotating the hand wheel 17. When the threaded rod 16 rotates, the two first connecting blocks 13 will approach each other. Because a plurality of fixing frames 11 are fixed on the upper end of the bottom plate 10, and the four end corners of the top of the fixing frame 11 are rotatably connected to the first connecting rod 12, when the threaded rod 16 rotates, the first connecting rod 12 and the second connecting rod 14 start to rotate. When the first connecting rod 12 and the second connecting rod 14 rotate, the height of the second connecting block 15 will be increased, and the second connecting block 15 will be moved closer to each other. Because the balance board 18 is fixed on the upper end of the second connecting block 15, when the second connecting block 15 rises, the balance board 18 also rises. A support plate 19 is fixed on the upper end of the bottom plate 10 and located at the bottom end of the balance board 18. A second through hole is opened on one side of the support plate 19, and the threaded rod 16 passes through the second through hole. Therefore, when the balance board 18 rises, the threaded rod 16 also rises, and the support plate 19 will not hinder the rise of the threaded rod 16, so that the height of the balance board 18 can be increased, thereby adjusting the height of the balance board 18, and gradually increasing the difficulty of the balance beam. A groove is provided at one end of the plate 10, and a plurality of evenly arranged first shock absorbing springs 21 are fixed in the groove. A shock absorbing plate 22 is fixed at the upper end of the first shock absorbing spring 21. When a child passes through the balance board 18, the shock absorbing plate 22 can prevent the child from falling down. The four end corners of the bottom end of the bottom plate 10 are provided with storage holes 25. The inside of the storage holes 25 is slidably connected with rollers 23. When the rollers 23 are not needed, the rollers 23 can be stored in the storage holes 25. Because the inside of the bottom plate 10 and the upper end of the rollers 23 are fixed with second shock absorbing springs 24, the bottom plate 10 A positioning hole 26 is provided on one side of the plate 10, and a first through hole matched with the positioning hole 26 is provided on the top of the roller 23. Therefore, when the children's physical training and exercise device needs to be moved, one end corner of the children's physical training and exercise device can be lifted. At this time, the roller 23 moves downward under the action of gravity and the second shock-absorbing spring 24. The roller 23 can be fixed by inserting a pin through the positioning hole 26. At this time, the children's physical training and exercise device can be moved. When it is moved to a suitable position, the pin is pulled out, and the roller 23 is stored in the storage hole 25 under the action of the bottom plate 10.

[0034] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
