TECHNICAL FIELD

[0001] The utility model relates to children's toys more specifically, it relates to balance training device. BACKGROUND

[0002] The utility model discloses a patent application number CN200820110008.3's utility model patent, discloses a kind of river-crossing stone infant fitness equipment, the scheme disclosed has base and convex platform, this scheme although can be convenient for infant use, can exercise infant lower limb muscle strength, develop its body coordination, balance sense and distance judgment ability, but also have certain safety problem simultaneously, infant once does not accurately step on the platform position of convex platform, if located inclined side, convex platform will produce sliding, infant falls and causes knock, therefore a kind of balance training device is needed, the device can combine each module, avoid mutual disengagement between module, to improve security.

[0003] In combination with above reason, how to combine each module is the problem considered in the present application. UTILITY MODEL CONTENT

[0004] In view of the deficiencies in the prior art, a balance training device is provided, which can combine each module to avoid mutual disengagement between modules, thereby improving security.

[0013] The utility model will be further described in detail below in combination with the drawings and examples. Identical parts are denoted by identical reference signs. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a particular part.

[0014] Reference Figures 1-4 As shown in the drawings, the balance training device comprises a first module 1 and a second module 2, the first module 1 is provided with a first connecting piece 3, the second module 2 is provided with a first surrounding piece 4, and when the first connecting piece 3 is surrounded by the first surrounding piece 4, the second module 2 limits the first module 1 from separating in the horizontal direction;

[0015] In the device, the first module 1 and the second module 2 can be of any shape, only the first connecting piece 3 and the first surrounding piece 4 have specific structures, the first connecting piece 3 and the first surrounding piece 4 are connected in the form of splicing, the splicing direction can be any non-horizontal direction, preferably vertical direction, so that when the first connecting piece 3 is surrounded by the first surrounding piece 4, the first module 1 and the second module 2 are respectively stressed to produce a mutual moving tendency, but since the device is used on a flat ground, the moving tendency is mainly in the horizontal direction, so that the non-horizontal splicing can form a resistance, thereby limiting the first module 1 from separating in the horizontal direction by the second module 2, and the resistance is the strongest in the case of vertical splicing;

[0016] The utility model discloses a first surrounding piece 4 surrounds the first connecting piece 3 and maintains the connection between the first module 1 and the second module 2, and through the abutting action between the side walls in the surrounding state, the various modules are combined, and meanwhile, the modules are prevented from being separated from each other, thereby improving the safety.

[0017] Further, the side surface of the first connecting piece 3 is provided with a step 7, and the first surrounding piece 4 is provided with a limiting surface 8 corresponding to the position of the step 7; when the first surrounding piece 4 is combined with the first connecting piece 3, the limiting surface 8 cooperates with the step 7 to limit the first connecting piece 3 from being separated from the first surrounding piece 4 in the longitudinal direction.

[0018] The first connecting piece 3 is outwardly convex at the position corresponding to the lower side to form a step shape;

[0019] After the plug-in installation is completed, the side surface of the step 7 abuts against the side surface of the limiting surface 8, thereby forming an abutting surface for resisting the horizontal force; in actual use, the stress direction is not only the horizontal direction, and usually, the stress direction can be decomposed into the horizontal direction and the vertical direction; the stress in the vertical direction is directly borne by the first connecting piece 3 or the first surrounding piece 4 alone; because the side surface of the first connecting piece 3 is provided with the step 7, the actual contact area with the ground is large, and the first connecting piece 3 has strong anti-damage performance; the first surrounding piece 4 is just the opposite, and therefore, the first connecting piece 3 is outwardly convex at the position corresponding to the lower side to form a step shape, and the limiting surface 8 cooperates with the step 7; in this way, the stress of the limiting surface 8 can be dispersed to the step 7, the anti-damage performance of the first surrounding piece 4 is increased, and meanwhile, the limiting surface 8 and the step 7 abut against each other in the up-down direction, thereby limiting the separation in the up-down direction and further reducing the possibility of separation, thereby improving the safety.

[0021] The cross section of the step 7 is circular arc-shaped, the shape of the limiting surface of the first surrounding piece is adapted to the step, and is fan-shaped and has a central angle greater than 180°

[0025] Further, the position where the connecting grids 5 are connected with the limiting surfaces 8 is flush with the limiting surfaces 8, so that the stress can be stably kept in the same horizontal direction, that is, the main stress direction of the connecting grids 5, thereby improving the damage resistance.
