[0009] In the technical solution, the structure of the reboundable dumbbell is reasonably set up. It can be used as a dumbbell for push-up training; it can also be used as an abdominal wheel. When the body is stretched forward, the first counterweight wheel is locked and the second counterweight wheel rotates, and the coil spring deforms to store energy; when it is stretched to the right position and retracted, the first counterweight wheel and the second counterweight wheel rotate at the same time, the coil spring relaxes and releases energy to provide rebound force, which is suitable for different people to exercise.

[0010] In some embodiments of the present application, the coil spring seat includes a circular first chassis, and a mounting ring arranged around the edge of the circular first chassis, the mounting ring is perpendicular to the first chassis, and a slot is formed at one end of the mounting ring close to the coil spring;

[0011] The outer end of the coil spring is provided with a bending portion, and the bending portion is placed outside the clamping slot. The coil spring is fixed on the coil spring seat. The rotation of the coil spring seat drives the bending portion to make a circular motion, so that the coil spring deforms and stores energy.

[0012] In some embodiments of the present application, the second counterweight wheel includes a second chassis close to the first counterweight wheel, an annular housing perpendicular to the second chassis, and a sealing plate arranged close to the coil spring, and a plurality of limit plates are evenly arranged on the second chassis along its radial direction;

The coil spring seat rotates synchronously with the second counterweight wheel, and the coil spring is deformed to store energy or rotates to reset accordingly.

[0014] In some embodiments of the present application, the locking mechanism passes through the rebound mechanism and is connected to the second counterweight wheel and the first counterweight wheel. The locking mechanism can tighten or loosen the coil spring according to the direction of movement and lock or unlock the first counterweight wheel for rotation.

[0015] In some embodiments of the present application, the locking mechanism includes a one-way bearing, a connecting end seat, and a connecting bolt. The one-way bearing is fixed on the connecting end seat. After the connecting bolt passes through the connecting end seat, the one-way bearing, the coil spring, the coil spring seat, and the second counterweight wheel in sequence, the other end of the connecting bolt is fixed to the axial position of the first counterweight wheel; when the one-way bearing moves rotatably, the first counterweight wheel rotates accordingly, and when it moves in the opposite direction, the one-way bearing is locked and the first counterweight wheel does not move.

[0016] In some embodiments of the present application, the locking mechanism is located on the outside of the sealing plate, the one-way bearing is arranged close to the sealing plate, and the one-way bearing and the second counterweight wheel move independently of each other.

[0017] In some embodiments of the present application, the first counterweight wheel and the handle are an integrated structure.

[0018] In some embodiments of the present application, when one of the second counterweight wheels is provided with the rebound mechanism, another second counterweight wheel is internally provided with a counterweight block having the same counterweight as that of the rebound mechanism to improve the balance of movement.

[0019] In some embodiments of the present application, an anti-slip ring is provided on the outer side of the annular shell of the second counterweight wheel to increase the friction with the ground. When rubbing against the ground, it is silent and has a strong grip, thereby improving the user experience.

[0020] Based on the above technical solution, the reboundable dumbbell of the embodiment of the utility model has a reasonable structure and can be used as a dumbbell for push-up training;

[0021] It can also be used as an abdominal wheel. The locking mechanism is set so that when the dumbbell moves away from the human body, the first counterweight wheel is locked and the second counterweight wheel rotates, and the coil spring deforms and stores energy. When the dumbbell moves toward the human body, the first counterweight wheel and the second counterweight wheel rotate at the same time, and the coil spring relaxes and releases energy. When the coil spring is reset, the dumbbell continues to move toward the human body. The coil spring provides rebound force, which increases the resistance when the dumbbell moves. It is suitable for different people to exercise.

[0022] The setting of the anti-skid ring increases the friction between the second counterweight wheel and the ground. It is silent and has a strong grip when rubbing against the ground, thereby improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] As attached Figure 1-Figure 2 As shown, the reboundable dumbbell of this embodiment includes:

[0033] The grip bar 10 is used as a dumbbell by holding the grip bar 10;

[0034] There are two dumbbell bodies 20, which are respectively arranged at the ends of the grip 10. The dumbbell body 20 includes a first counterweight wheel 21 connected to the end of the grip 10, and a second counterweight wheel 22 connected to the outer end of the first counterweight wheel 21 and parallel to each other. The first counterweight wheel 21 and the second counterweight wheel 22 are rotatably connected, and the rotation plane of the first counterweight wheel 21 is parallel to the rotation plane of the second counterweight wheel 22.

[0035] At least one second counterweight wheel 22 is provided with a rebound mechanism 50, which includes a coil spring seat 51 located inside the second counterweight wheel 22 and a coil spring 52 fixed on the coil spring seat 51. The coil spring seat 51 rotates with the second counterweight wheel 422, driving the coil spring 52 to deform and store energy or rebound and reset;

[0036] A locking mechanism 60 is provided at one end of the outer side of the second counterweight wheel 22. The locking mechanism 60 passes through the rebound mechanism 50 and the second counterweight wheel 22 in sequence, and then is connected to the first counterweight wheel 21. The locking mechanism 60 tightens or loosens the coil spring of the rebound mechanism according to the direction of movement, and locks or unlocks the first counterweight wheel 21 for rotation.

[0037] The resilient dumbbell of the present embodiment has a reasonable structure and can be used as a dumbbell for push-up training; it can also be used as an abdominal wheel. When the dumbbell moves away from the human body, the first counterweight wheel 21 is locked and immobilized, the second counterweight wheel 22 rotates, and the coil spring 52 deforms and stores energy. When the dumbbell moves toward the human body, the first counterweight wheel 21 and the second counterweight wheel 22 rotate at the same time, and the coil spring 52 relaxes and releases energy. When the coil spring 52 is reset, the dumbbell continues to move toward the human body. The coil spring 52 provides a rebound force, which increases the resistance when the dumbbell moves. It is suitable for different people to exercise.

[0038] Specifically, the coil spring seat 51 includes a circular first chassis 511 and a mounting ring 512 arranged around the outer edge of the circular first chassis 511, the mounting ring 512 is perpendicular to the first chassis 511, and the mounting ring 512 is provided with a slot 5121 extending horizontally along its width direction; a bending portion 521 is provided at the outer end of the coil spring 52, and the bending portion 521 is clamped on the outer side of the slot 5121 to fix the coil spring 52 on the coil spring seat 51, and the rotation of the coil spring seat 51 drives the bending portion 521 to make a circular motion, so that the coil spring 52 is deformed and stores energy.

[0039] like Figure 2 As shown, the second counterweight wheel 22 includes a second chassis 221 close to the first counterweight wheel 21, an annular shell 222 perpendicular to the second chassis 221, and a sealing plate 223 arranged opposite to the second chassis 221 and blocking the annular shell 222. A plurality of limit plates 224 are evenly arranged on the second chassis 221 along its radial direction.

[0040] A plurality of fixing grooves 5122 are formed on one side of the mounting ring 512 of the coil spring seat 51 close to the second chassis 4221. The limiting plate 224 on the second chassis 221 cooperates with the fixing grooves 5122 on the mounting ring 512, so that the coil spring seat 51 is fixed in the second counterweight wheel 22. The coil spring seat 51 rotates synchronously with the second counterweight wheel 22, driving the bent portion 521 of the coil spring 52 to rotate, and the coil spring 52 is deformed to store energy or rotate to reset.

[0041] Continue to see Figure 2The locking mechanism 60 includes a one-way bearing 61, a connecting end seat 62, and a connecting bolt 63. In this embodiment, the connecting end seat 62 is a hollow cylindrical structure, and the one-way bearing 61 is fixed on the connecting end seat 62. After the connecting bolt 63 passes through the connecting end seat 62, the one-way bearing 61, the center of the coil spring 52, the coil spring seat 51, and the second counterweight wheel 22 in sequence, the other end of the connecting bolt 63 is threadedly fixed to the axial position of the first counterweight wheel 21, and a linear groove (not shown in the figure) is opened along the length direction of the connecting bolt 63. The center position of the coil spring 52 is stuck in the linear groove, so that the connecting bolt 63 can pass through the center position of the coil spring 52 to fix the inside of the coil spring, so that the center position of the coil spring 52 remains fixed during the deformation and tightening process.

[0042] In this embodiment, the rotatable direction of the one-way bearing 61 is counterclockwise, and the one-way bearing 61 is locked and motionless when it rotates clockwise; when the dumbbell body 20 moves in a direction away from the human body, the second counterweight wheel 22 rotates clockwise, at this time the one-way bearing 61 is locked and motionless, and the first counterweight wheel 21 is fixed and motionless, because the coil spring 52 will rotate clockwise with the second counterweight wheel 22, and the coil spring 52 will deform and store energy in this process; when the movement is in place and the dumbbell body 20 returns in the opposite direction, the second counterweight wheel 22 rotates counterclockwise, and at this time the one-way bearing 61 also starts to rotate clockwise, driving the first counterweight wheel 21 to rotate counterclockwise accordingly; when moving in the rotatable direction of the one-way bearing 61, the one-way bearing 61 rotates to drive the connecting bolt 63 to rotate, and the connecting bolt 63 drives the first counterweight wheel 21 to rotate accordingly, and when moving in the opposite direction, the one-way bearing 61 is stationary, the first counterweight wheel 21 is locked and motionless, and the second counterweight wheel 22 always rotates during the forward and backward processes.

[0043] Among them, the locking mechanism 60 is located on the outside of the sealing plate 223, and the one-way bearing 61 is arranged close to the sealing plate 223. The one-way bearing 61 and the second counterweight wheel 22 move independently of each other. When moving clockwise, the one-way bearing 61 does not move, and the second counterweight wheel 22 rotates. When moving counterclockwise, both the one-way bearing 61 and the second counterweight wheel 22 rotate.

[0044] The first counterweight wheel 21 and the grip 10 are an integrated structure; an anti-skid ring 23 is provided on the outer side of the annular shell 222 of the second counterweight wheel 22 to increase the friction with the ground, and is silent and has a strong grip when rubbing against the ground, thereby improving the user experience.

[0045] In another embodiment, when only one second counterweight wheel 22 is provided with a rebound mechanism 50, a counterweight block (not shown in the figure) having the same counterweight as the rebound mechanism 50 is provided inside the other second counterweight wheel 22 to improve the balance of the movement.

[0046] The resilient dumbbell of the utility model has a reasonable structure and can be used as a dumbbell for push-up training; it can also be used as an abdominal wheel. The locking mechanism is set so that when the dumbbell moves in a direction away from the human body, the first counterweight wheel is locked and immovable, the second counterweight wheel rotates, and the coil spring deforms to store energy. When the dumbbell moves in a direction close to the human body, the first counterweight wheel and the second counterweight wheel rotate at the same time, the coil spring relaxes and releases energy. When the coil spring is reset, the dumbbell continues to move in a direction close to the human body, and the coil spring provides a rebound force, so that the resistance of the dumbbell increases when it moves, which is suitable for different groups of people to exercise.

[0047] The setting of the anti-skid ring increases the friction between the second counterweight wheel and the ground. It is silent and has a strong grip when rubbing against the ground, thereby improving the user experience.

[0048] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0049] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
