Abstract
Description
Technical Field
[0001] The utility model relates to fitness equipment, in particular to fitness equipment which can prevent a bell piece from rotating arbitrarily. Background Art
[0002] At present, the existing dumbbell bars, barbell bars, and kettlebell bars generally adopt a cylindrical structure, and accordingly, the center hole of the bell plate is a round hole. When a polygonal bell plate is used, if the locking nut is slightly loose during use, the bell plate will rotate arbitrarily, resulting in the bell plates being very uneven, inconvenient to place, and not very beautiful. Therefore, developing a fitness equipment that prevents the bell plates from rotating arbitrarily has become a problem that needs to be solved by those skilled in the art. Utility Model Content
[0003] The utility model aims to solve the above-mentioned drawbacks and provides a fitness equipment which can prevent bell plates from rotating arbitrarily.
[0004] The above-mentioned purpose of the utility model is achieved through the following technical scheme: a fitness equipment for preventing bell plates from rotating arbitrarily, comprising a bell bar and bell plates, wherein the bell bar is provided with a bell plate mounting portion, the bell plate mounting portion is a column with a non-circular cross section, and the shape of the central hole of the bell plate matches the cross-sectional shape of the bell bar.
[0005] Furthermore, the bell piece is polygonal, or any other non-circular shape.
[0006] Furthermore, the bell piece mounting portion is provided with a thread or a slot.
[0007] Furthermore, the bell piece mounting portion is a cylinder with an elliptical cross section, and correspondingly, the center hole of the bell piece is an elliptical hole.
[0008] Furthermore, the bell piece mounting portion is a column with a waist-shaped cross section, and correspondingly, the center hole of the bell piece is an elliptical hole.
[0009] Furthermore, the bell piece mounting portion is a column with a D-shaped cross section, and correspondingly, the center hole of the bell piece is a D-shaped hole.
[0010] Furthermore, the bell piece mounting portion is a column with a polygonal cross section, and accordingly, the central hole of the bell piece is a polygonal hole. The specific shape can be a triangle, quadrilateral, pentagon, hexagon, heptagon, octagon, enneagon, etc.
[0011] Compared with the prior art, the utility model has the advantages that when the bell piece adopts a polygonal or other arbitrary non-circular shape, the bell piece will not rotate arbitrarily on the bell rod to cause unevenness, and the bell piece is convenient to place and is neat and beautiful.
