DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] For example, Figures 1-4The utility model provides a technical scheme: a kind of inertial barbell piece, including barbell piece 1, it is characterized by: annular boss 101 is provided at the outer side of the front end and rear end of barbell piece 1, the outer side of annular boss 101 is provided with grab groove 103, grab hole 102 is provided in the outer side close to the front end of barbell piece 1, mounting hole one 104 is provided in the front end of barbell piece 1, inertia device 2 is installed in mounting hole one 104, spring 201 is arranged in inertia device 2, one end of spring 201 away from the inner wall of mounting hole one 104 is fixedly connected with counterweight one 202, counterweight two 203 is screw-connected in the middle of counterweight one 202, counterweight three 204 is screw-connected in the middle of counterweight two 203, mounting hole two 106 is provided in the middle of barbell piece 1, sleeve 3 is installed in mounting hole two 106, platform 301 is provided at the front end of sleeve 3, mounting pin 302 is provided at the rear end of platform 301, mounting groove 105 is provided in the middle of barbell piece 1.

[0023] Further, grab hole 102 and grab groove 103 are circumferentially distributed on barbell piece 1, and the positions of grab hole 102 and grab groove 103 are corresponding.

[0024] Through the above technical scheme, it is more convenient to pick up barbell piece 1 on the ground or take barbell piece 1 off the barbell rod.

[0025] Further, the edges of annular boss 101, grab hole 102 and grab groove 103 are all set as rounded structures.

[0026] Through the above technical scheme, when picking up barbell piece 1, the palm will not be squeezed due to the edges, so as to feel uncomfortable.

[0027] Further, the mounting groove 105 and the mounting pin 302 are circumferentially distributed on the platform 301 and in the middle of the barbell piece 1, and the mounting groove 105 and the mounting pin 302 are insertedly mounted.

[0028] Through the above technical scheme, it is ensured that the mounting groove 105 and the mounting pin 302 can be completely mounted together, so as to ensure that the sleeve 3 will not fall off during use.

[0029] Further, the springs 201 are circumferentially distributed in the inertia device 2, and the distribution of the springs 201 in the four inertia devices 2 is consistent.

[0030] Through the above technical scheme, it is ensured that the counterweight one 202 can generate inertia in all directions, so as to avoid that inertia cannot be generated due to misalignment.

[0031] Working principle: first adjust the inertia device 2, the counterweight is adjusted to the counterweight that can adapt to oneself, then the barbell piece 1 is installed on the barbell rod in turn, and the barbell piece 1 is fixed, ensure that the barbell piece 1 does not fall off, then when exercising, with the movement of the barbell piece 1, the counterweight one 202 will stay in place due to the inertia effect, then the spring 201 drives the counterweight one 202 to move, when the barbell piece 1 moves in the opposite direction, the counterweight one 202 still moves in the original direction, so the moving direction of the counterweight one 202 is always opposite to the moving direction of the barbell piece 1, so that the exerciser not only needs to bear the weight of the barbell piece 1 itself when exercising, but also needs to bear the inertia force of the counterweight one 202, the elasticity stimulation of the barbell piece 1 to muscle is enhanced, the technical effect that muscle fiber structure is reshaped and muscle explosive force is enhanced is achieved, and there is high practical value.

[0032] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
