Description

A connector that can be used to connect fitness equipment Technical Field

[0001] The utility model belongs to the technical field of fitness equipment and relates to a connector that can be used to connect fitness equipment. Background Art

[0002] With the improvement of living standards, exercise has become an important way for people to maintain physical and mental health. People usually use dumbbells, kettlebells, and barbells as the main fitness equipment. However, most dumbbells, kettlebells, and barbells on the market are not interchangeable. Users need to purchase dumbbells, kettlebells, and barbells separately to achieve a comprehensive fitness effect, which greatly increases fitness costs.

[0003] Patent Publication No. US20220355153A1 discloses a connector that connects a dumbbell to a handle to form a kettlebell structure; and two dumbbells and a long bar are connected via two connectors to form a barbell structure. This connector generally includes a first connector and a second connector that are hinged to each other, secured by a nut, making the connection time-consuming and labor-intensive.

[0004] To increase the difficulty of training, people tie the ends of an elastic cord to a barbell, step on the cord with both feet, and pull the barbell up as fast as possible to increase strength through this training method. However, the elastic cord is fixed to the barbell by tying it. Under the high-intensity pulling force, the connection between the elastic cord and the barbell will loosen. This fixing method is not only time-consuming and labor-intensive, but also poses a safety hazard. Technical issues

[0005] The purpose of the present invention is to solve the above problems existing in the existing fitness equipment connectors, and to propose a connector that can be quickly locked and connected to the fitness equipment, and the connection between the connector and the elastic rope is more convenient and firm.

Best Mode for Carrying Out the Invention

[0032] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0033] As shown in Figure 1, the present invention describes a connector that can be used to connect fitness equipment, including a first connector 1 and a second connector 2 that are hinged to each other. The first connector 1 and the second connector 2 enclose a clamping cavity for connecting the fitness equipment, and the clamping cavity includes a first clamping hole 4 and a second clamping hole 5 that are perpendicular to each other. The first clamping hole 4 is a through hole that penetrates front and back along its axial direction.

[0034] As shown in Figures 2 and 3, a buckle structure is provided between the first connecting member 1 and the second connecting member 2, which is used to lock or unlock the first connecting member 1 and the second connecting member 2. The buckle structure includes a fastener 6 rotatably arranged on the second connecting member 2 and a bayonet 7 opened on the second connecting member 2. A buckle plate 8 is fixed to the outer end of the fastener 6. After the fastener 6 is rotated and passed around the first connecting member 1, the fastener 6 is pressed so that the buckle plate 8 is elastically deformed and inserted into the bayonet 7 to form a lock.

[0035] The second connecting member 2 is fixedly provided with a rotating portion 9 integrally formed therewith, and the fastener 6 is rotatably mounted on this rotating portion 9. The outer end of the fastener 6 is tilted outward to form a pressing portion 10, and the aforementioned pinch plate 8 is fixedly mounted on the inner side of the pressing portion 10. The fastener 6, pressing portion 10, and pinch plate 8 are integrally formed.

[0036] As shown in Figure 4, a buckle 11 is provided on the outer wall of the first connecting member 1. A locking through-hole 3 is defined in the first connecting member 1 and communicates with the clamping cavity. A locking screw hole corresponding to the locking through-hole is defined on the fitness equipment mounted in the clamping cavity. A threaded rod is fixed to the end of the buckle 11, which passes through the locking through-hole 3 and is screwed into the locking screw hole on the fitness equipment.

[0037] The first connector 1 is also provided with an abutment piece 15, which is used to cover the gap between the first connector 1 and the second connector 2 when the first connector 1 is rotated to be locked with the second connector 2. The abutment piece 15 makes the overall structure of the assembled connector more stable.

[0038] A first groove 16 is provided on the first connecting member 1, and a second groove 17 is provided on the second connecting member 2. When the first connecting member 1 is rotated to be engaged and locked with the second connecting member 2, the first groove 16 and the second groove 17 are combined up and down to form the above-mentioned first clamping hole 4; a third groove 18 is provided on the first connecting member 1, and a fourth groove 19 is provided on the second connecting member 2. When the first connecting member 1 is rotated to be engaged and locked with the second connecting member 2, the third groove 18 and the fourth groove 19 are combined up and down to form the above-mentioned second clamping hole 5.

[0039] A first anti-slip pad is embedded in the first groove 16, and a second anti-slip pad is embedded in the second groove 17. The first and second anti-slip pads both have semicircular cross-sections. When the first connector 1 is rotated to engage and lock with the second connector 2, the first and second anti-slip pads combine to form an anti-slip hole. When the dumbbell is inserted into the first clamping hole 4, the dumbbell is restrained by the anti-slip hole and is less likely to slip.

[0040] A fixing rod 20 is fixed to the fitness equipment installed in the second clamping hole 5. The fitness equipment is inserted into the first clamping hole 4 through the fixing rod 20. The locking screw hole is provided on the fixing rod 20. A plurality of protrusions 12 are fixed to the inner wall of the second clamping hole 5, and a plurality of slots corresponding to the protrusions 12 are provided on the outer wall of the fixing rod 20.

[0041] The fitness equipment mounted in the second clamping hole 5 can be a handle 21 or a long pole 22. A fixing rod 20 is fixed to the handle 21. As shown in FIG4 , the handle 21 is mounted in the second clamping hole 5 via the fixing rod 20, and the dumbbell is mounted in the first clamping hole 4 to form a kettlebell structure. Because the protrusions 12 are evenly spaced around the circumference of the second clamping hole 5, the handle 21 can be rotated 90 degrees relative to the second clamping hole 5 to adjust to different training postures.

[0042] As shown in FIG5 , a fixing rod 20 is provided at each end of the long rod 22 , and the two ends of the long rod 22 are respectively installed in the second clamping holes 5 through the fixing rods 20 , and the two dumbbells are respectively installed in the first clamping holes 4 of the two connecting parts to form a barbell structure.

[0043] As shown in Figure 6, a connector is mounted on each end of a long pole 22. A spring lock is secured to each end of an elastic cord 23, and the two spring locks are respectively connected to the buckles 11 of the two connectors. During use, the long pole 22 is pulled by stepping on the elastic cord 23 to increase the tensile resistance. A single long pole 22 can be used with one or more elastic cords 23, and elastic cords of different weights can be used as needed, allowing for a variety of usage options. The elastic cord 23 and the connector are quick and easy to install, and the connection is more secure.

[0044] During installation, open the fastener 6, flip the first connecting member 1 upward, place the dumbbell into the first clamping hole 4, place the handle or long rod into the second clamping hole 5, flip the first connecting member 1 downward and fasten the fastener 6, and pass the buckle 11 through the locking through hole 3 and fix it to the locking screw hole on the fitness equipment.
