Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a weighted ball that prevents it from falling off. Background Technology

[0002] A weighted jump rope is a fitness device that uses weights for resistance training, typically equipped with a weighted ball. Using a weighted jump rope can enhance fat burning and body shaping effects. The weight can be adjusted to suit individual needs.

[0003] Currently, the connection between the weighted ball and the rope is a simple buckle, which makes it easy for the rope to detach from the weighted ball during exercise. If the weighted ball detaches and flies out, it may cause injury. Therefore, the stability of the installation between the weighted ball and the rope needs to be improved. Utility Model Content

[0004] The present invention aims to provide a non-detachable weighted ball to solve the problem mentioned in the background art, which is that the connection between the weighted ball and the rope is a simple buckle, making it easy for the rope to detach from the weighted ball during exercise and swinging. The detached weighted ball may fly out and cause injury, thus the stability of the installation between the weighted ball and the rope needs to be improved.

[0005] The technical solution adopted by this utility model to solve the technical problem is as follows: a weighted ball for preventing slippage, comprising a ball, a counterweight, and a rope. The ball has an internal cavity for receiving the counterweight, which is interference-fitted. The counterweight has a limiting groove and a through hole inside. The top of the limiting groove communicates with the through hole. A horizontal block is provided at the end of the rope. The rope passes through the through hole, causing the horizontal block to be confined in the limiting groove. The horizontal block abuts against the peripheral wall of the limiting groove.

[0006] Preferably, the diameter of the limiting groove is larger than the through hole, and the diameter of the transverse block is larger than the through hole.

[0007] Preferably, the counterweight includes at least one boss provided on the sidewall of the counterweight.

[0008] Preferably, the boss is larger at the top and smaller at the bottom, resembling an inverted "eight" shaped trumpet.

[0009] Preferably, the sphere is made of an elastic material.

[0010] Preferably, the counterweight is made of metal.

[0011] Preferably, the counterweight and the boss are integrally formed.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, the internal cavity of the sphere is interference-fitted with the counterweight, allowing the counterweight to be securely installed within the cavity. The top of the limiting groove communicates with the through hole, allowing the rope to pass through and confine the horizontal block within the limiting groove. The horizontal block abuts against the periphery of the limiting groove, achieving a tight fit. Thus, the rope is securely connected to the counterweight via the horizontal block. This invention securely installs the counterweight inside the sphere, and the limiting groove of the counterweight limits the horizontal block of the rope, with the horizontal block tightly fitted to the limiting groove. This ensures good fixation between the rope and the sphere during use, preventing it from falling off. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0026] Example 1, please refer to Figures 1 to 5 As shown, this utility model provides the following technical solution: a weighted ball 100 for preventing slippage, comprising a ball 10, a counterweight 20, and a rope 30. The ball 10 has an internal cavity 101 for accommodating the counterweight 20 and for interference fit. The counterweight 20 has a limiting groove 202 and a through hole 2021 inside. The top of the limiting groove 202 communicates with the through hole 2021. The end of the rope 30 is provided with a horizontal block 301. The rope 30 passes through the through hole 2021 so that the horizontal block 301 is confined in the limiting groove 202. The horizontal block 301 abuts against the peripheral wall of the limiting groove 202.

[0027] In the anti-fall-off weighted ball 100 provided in this embodiment, the receiving cavity 101 inside the ball 10 is interference-fitted with the counterweight 20, so that the counterweight 20 can be stably installed in the receiving cavity 101 inside the ball 10. The top of the limiting groove 202 communicates with the through hole 2021, so that the rope 30 passes through the through hole 2021 and the horizontal block 301 is limited in the limiting groove 202. The horizontal block 301 and the peripheral wall of the limiting groove 202 are pressed together to achieve a tight fit. Thus, the rope 30 is stably connected to the counterweight 20 through the horizontal block 301. This utility model, by stably installing the counterweight 20 inside the ball 10, and then limiting the horizontal block 301 of the rope 30 with the limiting groove 202 of the counterweight 20, and with the horizontal block 301 and the limiting groove 202 tightly fitted, ensures good fixation between the rope 30 and the ball 10 during use, preventing it from falling off.

[0028] The rope 30 and the horizontal block 301 can be integrally formed or they can be connected separately.

[0029] Preferably, the diameter of the limiting groove 202 is larger than that of the through hole 2021, and the diameter of the horizontal block 301 is larger than that of the through hole 2021. This arrangement allows the horizontal block 301 to be confined within the limiting groove 202.

[0030] Preferably, the counterweight 20 includes at least one boss 201 provided on the side wall of the counterweight 20. When the receiving cavity 101 inside the sphere 10 is interference-fitted with the counterweight 20, since the sphere 10 is made of elastic material, the boss 201 provided on the side wall of the counterweight 20 inserts into the side wall of the receiving cavity 101 for engagement, thereby the counterweight 20 is securely installed in the receiving cavity 101 inside the sphere 10.

[0031] Preferably, the boss 201 is larger at the top and smaller at the bottom, resembling an inverted "eight" shaped trumpet. This design of the boss 201 makes it easy for the counterweight 20 to be inserted into the receiving cavity 101 inside the sphere 10, and the boss 201 is inserted into the side wall of the receiving cavity 101 of the sphere 10, forming an inverted shape, which makes it difficult for the counterweight 20 to be pulled out of the sphere 10 or thrown out during movement.

[0032] Preferably, the sphere 10 is made of an elastic material. The elastic material can be, for example, a sponge.

[0033] Preferably, the counterweight 20 is made of metal. The metal material can be, for example, lead or iron.

[0034] Preferably, the counterweight 20 and the boss 201 are integrally formed. Integrating the counterweight 20 and the boss 201 together enhances the stability.

[0035] Example 2, please refer to Figure 6 and Figure 7 As shown, unlike Embodiment 1, the counterweight 20 is composed of an outer shell 203 and an inner core 204. The inner core 204 is housed inside the outer shell 203. At least one boss 201 is provided on the side wall of the outer shell 203. A limiting groove 202 is formed inside the inner core 204. A through hole 2021 is connected to the top of the limiting groove 202. The rope 30 passes through the through hole 2021 to limit the horizontal block 301 in the limiting groove 202.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
