It should be noted that the supports 4 are disposed at two ends of the handle 3, that is, two supports 4 are disposed at two ends of the handle 3 respectively; when the dumbbell is in horizontal position, the focus of above-mentioned fixing base 2, locate on fixing base 2 all balancing weights 1 as an organic whole the focus and the focus of support 4 all with the focus of handle 3 on same vertical line, guarantee also that the dumbbell can not incline the upset when being horizontal state.

The outline shape of the handle 3 is preferably designed into a cylindrical shape or a radish shape and other linear shapes according to actual requirements; of course, the handle 3 may be designed to be bent, that is, the grip portion of the handle 3 protrudes, so that the grip portion of the handle 3 and the two ends of the handle 3 are not in the same line, so as to use the dumbbell as a pot-shaped dumbbell or a push-up support.

In order to avoid the design of edges and corners, as shown in fig. 2 and 3, the surface shape of the above-mentioned fixed seat 2 is preferably circular, and for the requirement of beauty, the surface shape of the fixed seat 2 is further preferably in a shape of a perfect circle, wherein, the handle 3 is arranged between the inner rings of the fixed seat 2, taking the cylindrical handle 3 as an example (and taking the cylindrical as an example hereinafter), that is, the support 4 is arranged between the inner rings of the fixed seat 2, so that the center of gravity of the whole dumbbell coincides with the center of gravity of the handle 3; each support 4 comprises two connecting surfaces for connecting with the surface of the fixed seat 2 and a supporting surface arranged between the two connecting surfaces and used for connecting the end part of the handle 3. Of course, the surface shape of the fixing seat can also be an elliptical ring shape.

In a first embodiment, as shown in fig. 2 and 3, the fixing base 2 includes two fixing plates 21 arranged in parallel, and a supporting bolt 22 is arranged between the two fixing plates 21 to maintain the position of the two fixing plates 21 unchanged, so as to arrange the counterweight 1 between the two fixing plates 21; the two connecting surfaces of the support 4 are arranged in parallel, the supporting surface is perpendicular to the connecting surfaces, and the end part of the handle 3 is arranged at the central position of the supporting surface and fixed by a screw. Preferably, the fixed disk 21 is in a shape of a right circular ring; eight supporting bolts 22 are evenly and symmetrically arranged near the inner ring of the fixed plate 21 in four groups, namely, two adjacent groups of supporting bolts 22 form an angle of 90 degrees with the center of the handle 3, wherein the connecting surface of the support 4 is connected with the inner surface of the fixed plate 21, and the support 4 also plays a role of supporting the fixed plate 21 together with the supporting screw rods.

It should be noted that the above two, eight, four and so on numbers are only examples, and the specific values thereof should be determined according to actual situations; the shape of the fixed disk 21 is not limited to a perfect circular ring, and may be other shapes such as an elliptical ring or a square ring; if the fixing base 2 has three or more fixing plates 21, in order to ensure that the center of gravity of the whole dumbbell is located on the handle 3, the two connecting surfaces of the support 4 should be fixedly connected with the inner surfaces of the two fixing plates 21 at the outermost sides through the supporting bolts 22.

In order to fully utilize the surface space of the fixing plate 21 and meet the requirement of aesthetic appearance, as shown in fig. 2 and 3, the ring shape of the counterweight 1 surrounding the handle 3 is preferably consistent with the surface shape of the fixing seat 2, that is, when the fixing plate 21 is in the shape of a perfect circular ring, the counterweight 1 is distributed around the handle 3 in a perfect circle, that is, the center of gravity of all the counterweights 1 is located on the contour of the perfect circle, and the handle is located inside the contour of the perfect circle.

Of course, the weight member 1 may be disposed around the handle 3 in an elliptical or rectangular shape.

In order to ensure that the palm can grip the handle 3 tightly, the surface of the handle 3 is further provided with an anti-slip part for avoiding palm slip, preferably, the anti-slip part is of a knurled structure, namely, the surface of the handle 3 is knurled, and of course, the anti-slip part can also be other anti-slip sleeves capable of inhibiting palm slip; the particular shape configuration of the knurls and of the anti-slip sleeve can be referred to in the prior art and is not expanded herein.

In order to maximize the balance of the dumbbell, all the weights 1 provided on the fixing base 2 are uniformly and symmetrically distributed around the handle 3.

In the second embodiment, all the balancing weights 1 are in a column shape, and taking the multiple balancing weights 1 distributed in a perfect circle as an example, as shown in fig. 3, twelve balancing weights 1 are uniformly and symmetrically distributed around the handle 3, that is, an angle of 36 degrees is formed between any two adjacent balancing weights 1 and the center of the handle. No matter which direction the dumbbell inclines to overturn by the same angle, the torques generated by all the balancing weights 1 are all close, namely the pressures borne by the wrists are all close, so that the balance of the dumbbell is ensured to the maximum extent. Of course, if the balance weights 1 are uniformly distributed in other shapes, the torques generated by all the balance weights 1 are close to each other to the greatest extent no matter which direction the dumbbell is inclined and turned over at the same angle, so that the pressure applied to the wrist is close to the greatest extent, and the dumbbell can achieve the maximum balance according to the distribution shape of the current balance weights 1.

It should be noted that, the counterweight block 1 is preferably fixed to the fixing base 2 by screws, so as to be convenient to detach and mount; the shape of the counterweight block 1 is preferably a right cylinder; the twelve and 36 ° values are only examples, and the specific number of the weight blocks 1 should be determined according to actual conditions; if the number of the weight blocks 1 is larger, that is, the weight blocks 1 are denser, the balance of the dumbbell is better.

It can be understood that the dumbbell should be able to increase or decrease the number of the counter weight blocks 1 according to the needs of the trainee, if the counter weight blocks 1 are directly assembled and disassembled according to the alignment, the balance of the dumbbell may be reduced, and for this reason, the fixing seat 2 is provided with at least one positioning group with fixing positions which are uniformly and symmetrically distributed along the radial direction; wherein, the fixing position is used for arranging a screw to fix the position of the balancing weight 1.

When the dumbbell is inclined and turned over at the same angle in any direction, the torque generated by the balancing weight 1 is the same, namely the pressure on the wrist is the same, so that the balance of the dumbbell is ensured to the maximum extent.

In the fifth embodiment, for convenience of assembly and disassembly, each of the annular columnar counterweights 1 is preferably divided into two semicircular counterweights with the same size, and the positions of the two semicircular counterweights are fixed by fixing bolts. When needs dismouting balancing weight 1, take off the current outer lane (apart from handle 3 farthest promptly) balancing weight 1's fixing bolt, it is fixed with outer lane's balancing weight 1 through fixing bolt behind the dismouting balancing weight 1, wherein, in order to avoid the balancing weight 1 of inner circle to take place to rock, arbitrary two adjacent ring column balancing weights 1 can laminate, that is, the outer loop surface of inner circle balancing weight 1 laminates with the inner ring surface of outer lane balancing weight 1, and then can be through the position of only fixed outer lane balancing weight 1 with the position of fixed whole balancing weight 1.

It should be noted that, the conventional setting such as the mass and the volume of the weight block 1 in this document is not specifically limited, and should be determined according to the actual situation.
