Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a new technical solution: a dumbbell for training biceps comprises a holding rod 1, wherein two limiting discs 5 are rotatably connected to the holding rod 1, a balancing weight 3 is movably connected to the holding rod 1, a through hole 301 matched with the holding rod 1 is formed in the balancing weight 3, the balancing weight 3 is positioned on one side of the two limiting discs 5, the holding rod 1 is in threaded connection with a nut 4, a cross-shaped rotating handle 401 is fixedly adjusted on the nut 4, and a hand training mechanism is arranged on the limiting discs 5;

furthermore, the holding rod 1 is provided with anti-skid grains 103, the lower surface of the holding rod 1 is fixedly connected with a protective belt 2, and the anti-skid grains 103 and the protective belt 2 are both positioned between the two limiting discs 5;

through the rotating handle 401 arranged on the nut 4, when the weight block 3 needs to be increased and decreased, the rotating handle 401 is rotated to separate the nut 4 from the holding rod 1, so that the weight block 3 can be increased and decreased conveniently, the whole weight of the dumbbell is changed, and the dumbbell can be adjusted according to the capacity of a user;

through the arranged anti-slip lines 103, the friction force between a user and the holding rod 1 is increased, the holding rod 1 is more stable when the holding rod is held by the user, and the phenomenon of slipping is avoided;

further, the hand exercising mechanism comprises a sliding plate 6 arranged on the holding rod 1, an internal groove 101 is formed in the holding rod 1, the sliding plate 6 is connected inside the internal groove 101 in a sliding mode, one end, not in contact with the internal groove 101, of the sliding plate 6 is fixedly connected with a pressure rod 601, and two ends of the pressure rod 601 are respectively attached to the arc-shaped surfaces of the two limiting discs 5;

furthermore, accommodating grooves 501 are formed in the opposite sides of the two limiting discs 5, springs 502 are fixedly connected inside the accommodating grooves 501, the accommodating grooves 501 are multiple, the elasticity of the springs 502 inside the accommodating grooves 501 is different, and the pressure rod 601 is matched with the accommodating grooves 501;

through the pressure rod 601, when the dumbbell needs to be used for exercise, the two limiting discs 5 are rotated to enable the accommodating groove 501 on the limiting discs 5 to be vertical to the pressure rod 601, so that the pressure rod 601 and the holding rod 1 are held by hands, the pressure rod 601 is forced to slide into the accommodating groove 501 to be in contact with the spring 502, at the moment, along with the continuous force generation of the hands, the slide plate 6 is contracted into the accommodating groove 101 due to the stress of the pressure rod 601, the pressure rod 601 is attached to the holding rod 1, at the moment, the spring 502 is squeezed by the pressure rod 601 to be contracted, therefore, due to the intervention of the spring 502, when an exerciser uses the dumbbell to exercise, the continuous force generation of the hands is needed to control the attachment between the pressure rod 601 and the holding rod 1, and then the hand strength and the biceps of the user are exercised simultaneously, so that the function of the dumbbell is not single, and further, the hand strength and the arm strength can be trained simultaneously, thus improving the diversity of the dumbbell;

the elasticity of the spring 502 in the accommodating groove 501 is different, so that the elasticity of the spring 502 can be controlled by the automatic ability of a user, the hand strength can be gradually exercised, the muscle injury phenomenon caused by the mismatch of the hand strength and the user ability is avoided, and the safety in the exercising process is improved;

furthermore, the clamping groove 102 is formed in the holding rod 1, the inner walls of the two limiting discs 5 are both provided with auxiliary grooves 7, tension springs 701 are fixedly connected inside the auxiliary grooves 7, one ends, not in contact with the auxiliary grooves 7, of the tension springs 701 are fixedly connected with clamping rods 702, one ends, not in contact with the tension springs 701, of the clamping rods 702 are arc-shaped, and one ends, not in contact with the tension springs 701, of the clamping rods 702 are movably clamped inside the clamping groove 102;

further, the clamping groove 102 and the auxiliary groove 7 are arranged annularly and have the same internal structure;

the clamping rod 702 is movably clamped in the clamping groove 102, so that when the limiting disc 5 rotates, the clamping rod 702 is stressed to retract into the auxiliary groove 7, when the limiting disc 5 rotates to a specified position, the tension spring 701 releases thrust to clamp the clamping rod 702 into the clamping groove 102 again, and the fixing of the limiting disc 5 is completed, so that the phenomenon that the limiting disc 5 rotates randomly in the using process of the dumbbell is avoided, and the pressure rod 601 can accurately slide into the accommodating groove 501, and therefore the hand strength and the arm strength can be trained simultaneously;

the working principle is as follows: through the pressure rod 601, when the dumbbell needs to be used for exercise, the two limiting discs 5 are rotated to enable the accommodating groove 501 on the limiting discs 5 to be vertical to the pressure rod 601, so that the pressure rod 601 and the holding rod 1 are held by hands, the pressure rod 601 is forced to slide into the accommodating groove 501 to be in contact with the spring 502, at the moment, along with the continuous force generation of the hands, the slide plate 6 is contracted into the accommodating groove 101 due to the stress of the pressure rod 601, the pressure rod 601 is attached to the holding rod 1, at the moment, the spring 502 is squeezed by the pressure rod 601 to be contracted, therefore, due to the intervention of the spring 502, when an exerciser uses the dumbbell to exercise, the continuous force generation of the hands is needed to control the attachment between the pressure rod 601 and the holding rod 1, and then the hand strength and the biceps of the user are exercised simultaneously, so that the function of the dumbbell is not single, and further, the hand strength and the arm strength can be trained simultaneously, thus improving the diversity of the dumbbell;

through the inside of the card pole 702 activity joint at draw-in groove 102 that sets up, consequently when rotating spacing dish 5, inside of card pole 702 atress retraction auxiliary groove 7, consequently when spacing dish 5 rotates the assigned position, extension spring 701 release thrust is gone into card pole 702 inside into draw-in groove 102 once more, accomplish fixed to spacing dish 5, consequently avoid the dumbbell to appear random pivoted phenomenon in spacing dish 5 in the use, and then confirm the inside that slips into holding tank 501 that pressure pole 601 can be accurate, consequently, the realization trains simultaneously hand strength and arm strength.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
