[0002] With the improvement of living standards, exercise has become an important way for people to maintain physical and mental health. People typically use dumbbells, kettlebells, and barbells as their main fitness equipment. However, most dumbbells, kettlebells, and barbells on the market are not interchangeable, requiring users to purchase them separately to achieve comprehensive fitness results, thus significantly increasing fitness costs.

[0003] Chinese utility model patent CN215609069U discloses an adapter for fitness equipment. The patent includes an appendix... Figure 5 In this design, two connectors are mounted at both ends of a handle, each connecting to one dumbbell, allowing it to be used as a barbell. The connectors are secured by creating positioning grooves in the handle and corresponding protrusions on the inner walls of the connector's clamping holes. These protrusions mate with the positioning grooves. This method of connector installation requires the purchase of a specific handle.

[0004] Currently available barbell bars have threaded sections at both ends, with barbell plates fitted onto these sections and secured to the barbell bar with nuts. However, existing barbell bars cannot be installed and fixed with the connector described in the aforementioned patent when the user already owns a barbell bar and dumbbells. Therefore, a universal connector for installing and fixing existing barbell bars is currently lacking. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems with existing fitness equipment connectors by proposing a connector that can be universally installed with existing barbell bars.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A connector for mounting a barbell bar includes a first connector and a second connector that are hinged to each other. Both ends of the barbell bar have a threaded section. The first connector and the second connector enclose a clamping cavity for mounting the threaded section of the barbell bar. A fixing member is also provided in the clamping cavity for locking the connector onto the threaded section of the barbell bar.

[0008] In the aforementioned connector for mounting a barbell bar, the fixing member is sleeved on the outer periphery of the threaded section, and the clamping cavity of the connector has an installation slot that matches the shape of the fixing member. The fixing member is embedded in the installation slot, and the fixing member is fixedly connected to the barbell bar through a detachable connection structure to limit the displacement of the barbell bar relative to the connector.

[0009] In the aforementioned connector for mounting a barbell bar, the detachable connection structure includes a fastening screw. A threaded hole is provided on the fastening component. The fastening screw is screwed into the threaded hole, and the inner end of the fastening screw presses against the threaded section of the barbell bar to fix the fastening component to the barbell bar.

[0010] In the above-mentioned connector for installing a barbell bar, the first connector has a recessed hole. After the fastening screw is tightened, the first connector is flipped over to cover the second connector. At this time, the position of the recessed hole corresponds vertically to the position of the threaded hole. The outer end of the fastening screw is embedded in the recessed hole to restrict the rotation of the fixing member relative to the connector.

[0011] In the aforementioned connector for mounting a barbell bar, the connector further includes a sleeve. The outer wall of the fixing member has an external threaded section that extends out of the connector. The sleeve is screwed and fixed onto the external threaded section. The threaded section of the barbell bar is divided into an installation section and an exposed section along its length. The installation section is located inside the clamping cavity of the connector, and the exposed section is located outside the connector.

[0015] In the aforementioned connector for mounting a barbell bar, the first connector has a first recess, and the second connector has a second recess. When the first connector rotates to engage and lock with the second connector, the first and second recesses fit together to form the first clamping hole. The first connector also has a third recess, and the second connector has a fourth recess. When the first connector rotates to engage and lock with the second connector, the third and fourth recesses fit together to form the second clamping hole.

[0016] In the aforementioned connector for mounting a barbell, a first anti-slip pad is embedded in the first recess, and a second anti-slip pad is embedded in the second recess. When the first connector rotates to engage and lock with the second connector, the first and second anti-slip pads combine to form an anti-slip hole. When the dumbbell is inserted into the first clamping hole, the dumbbell is restricted by the anti-slip hole, thus preventing it from slipping.

[0017] Compared with the prior art, the connector described in this utility model can be installed on the threaded section of an existing barbell bar. The connector is universally compatible with existing barbell bars, and the installation method is simple, convenient and quick. Attached Figure Description
