Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, and in particular to a double-sphere bouncy ball. Background Technology

[0002] A bouncy ball, also known as a slimming ball or fitness ball, is used by standing on a platform and then using the movement of their feet to propel the ball upwards with their body. Upon landing, the elasticity of the rubber ball propels the body up and down, achieving a slimming and fitness effect. Because the upper part of the rubber ball is convex, most bouncy balls currently have a hollow casing in the middle for assembly. This limits the number of rubber balls that can be used, but the rebound force provided by a single ball is limited, especially affecting the user experience for heavier users. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a double-sphere bouncy ball.

[0004] The technical solution adopted by this utility model is: a double-sphere bouncy ball, including a pedal, an elastic rope and a handle connected above the pedal, and two sets of bouncy ball assemblies fixed at intervals below the pedal. Each bouncy ball assembly includes a connecting seat, a bearing ring and a hemispherical rubber ball. The connecting seat is fixed to the lower surface of the pedal, and the bearing ring is sealed and fixed to the connecting seat. The bearing ring is provided with a sealing groove, and the open end of the rubber ball is inserted into the sealing groove to maintain a sealed and fixed position.

[0005] Furthermore, the lower surface of the pedal is provided with a plurality of positioning grooves corresponding to the connecting seat, and the connecting seat is provided with positioning bosses, which are embedded in the positioning grooves.

[0006] Furthermore, the bottom of the positioning boss is provided with an annular connecting edge, and the annular connecting edge is provided with a plurality of screw holes. The lower surface of the pedal is provided with a plurality of fixing holes, and fixing screws connected to the fixing holes are inserted into the screw holes.

[0007] Furthermore, the positioning boss has a hollow cavity with an open bottom end, the hollow cavity is connected to the rubber ball, and the open end of the hollow cavity has a locking groove, in which the bearing ring is sealed and fixed.

[0008] Furthermore, the rubber ball is provided with a vertical connecting section, which is inserted into the sealing groove, and the bottom of the rubber ball is provided with an air plug.

[0009] Compared with the prior art, this utility model has the following beneficial effects:

[0010] In this invention, a hemispherical rubber ball, together with a bearing ring and a connecting seat, forms a sealed bouncing ball assembly. The bouncing ball assembly is connected to the pedal via the connecting seat to avoid having an upwardly bulging hollow shell on the pedal. The use of multiple rubber balls enhances the rebound force of this product, thereby covering the usage needs of a wider range of people. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] See Figure 1This utility model provides a double-sphere bouncy ball, including a pedal 1. An elastic rope 2 and a handle 3 are connected to the upper part of the pedal 1. Two sets of bouncy ball assemblies 4 are fixed at intervals below the pedal 1. Preferably, the two bouncy ball assemblies 4 are symmetrically arranged at both ends of the pedal 1. (See reference...) Figure 2 The bouncing ball assembly 4 includes a connecting seat 41, a support ring 42, and a hemispherical rubber ball 43. The connecting seat 41 is fixed to the lower surface of the pedal 1, and the support ring 42 is sealed and fixed to the connecting seat 41. The support ring 42 is provided with a sealing groove 421. The open end of the rubber ball 43 is inserted into the sealing groove 421 to maintain a sealed fixation. The connecting seat 41, the support ring 42, and the rubber ball 43 together form a complete sealed cavity. When the sealed cavity is inflated, the rubber ball 43 can generate elasticity. By setting the connecting seat 41, the pedal 1 avoids the need for an upwardly bulging hollow clearance cavity, thus meeting the setting requirements of multiple sets of bouncing ball assemblies 4 and improving the rebound performance of this product.

[0020] See Figure 2 , 3 The lower surface of the pedal 1 is provided with a plurality of positioning grooves 11 corresponding to the connecting seat 41. The connecting seat 41 is provided with positioning bosses 411. By engaging the positioning bosses 411 with the positioning grooves 11, it is ensured that the bouncing ball assembly 4 will not move laterally relative to the pedal 1 during use after the product is assembled, thus ensuring the user's safety.

[0021] See Figure 2 The bottom of the positioning boss 411 is provided with an annular connecting edge 412, and the annular connecting edge 412 is provided with a plurality of screw holes 413. The lower surface of the pedal 1 is provided with a plurality of fixing holes 12, and fixing screws are inserted into the screw holes 413. The connecting seat 41 is fixedly connected to the pedal 1 by the cooperation of the fixing screws and the fixing holes 12.

[0022] See Figure 3 The positioning boss 411 has a hollow cavity 414 with an open bottom. The hollow cavity 414 reduces the material used in the production of the connecting seat 41. The hollow cavity 414 is connected to the rubber ball 43. The open end of the hollow cavity 414 has a locking groove 415. During assembly, the bearing ring 42 is first locked into the locking groove 415, and then the two are sealed and fixed to ensure the installation position and sealing effect of the bearing ring 42.

[0023] See Figure 2 , 3The rubber ball 43 is provided with a vertical connecting section 431, which is inserted into the sealing groove 421. The vertically arranged connecting section 431 fits more completely with the sealing groove 421, thereby improving the sealing effect between the rubber ball 43 and the bearing ring 42. The bottom of the rubber ball 43 is provided with an air plug 432 for inflation.

[0024] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
