The present disclosure relates to the technical field of dumbbell racks, in particular to a rotary dumbbell rack.
A dumbbell rack is an instrument for placing dumbbells. After the dumbbells are placed on the traditional dumbbell rack, the positions are fixed, the dumbbells cannot be rotated, and it is inconvenient for an exerciser to take and place the dumbbells, which brings great inconvenience to a usage process.
The present disclosure aims to provide a rotary dumbbell rack to overcome the defects and deficiencies in the prior art.
In order to achieve the above purpose, the technical solution adopted in the present disclosure is as follows: the rotary dumbbell rack comprises a base, wherein a plurality of expansion bolts are arranged on the base; a rotating shaft and a plurality of triangular supporting plates are arranged at the center of the base; the triangular supporting plates are distributed around the rotating shaft to clamp and fix the rotating shaft; bearings are arranged at upper and lower ends of the rotating shaft; a rotating sleeve is sleeved outside each of the bearings; square connecting tubes are arranged on left and right sides of each of the rotating sleeves; an outer cylinder is arranged on the square connecting tubes by means of connecting plates and bolts; the outer cylinder and the rotating shaft are arranged in a concentric circle form; a plurality of dumbbell placement plates are arranged on an outer side of the outer cylinder, every two of the dumbbell placement plates form a group, and the groups are arranged at equal intervals; and a plurality of placement grooves are longitudinally formed in each of the dumbbell placement plates at equal intervals.
Further, a decorative cover plate is arranged at the top of the outer cylinder.
Further, reinforcing plates are further arranged at upper and lower ends between each of the groups of the dumbbell placement plates.
Further, a rubber pad of an arc-shaped structure is sleeved on each of the placement grooves.
Further, the base is of a flower-shaped structure.
Further, the square connecting tubes at the upper and lower ends of the rotating shaft are distributed in a cross shape in space.
Further, the bearings are fixed by means of outer hoops, and the bearings are fixedly connected to the rotating sleeves by means of inner hoops.
With the adoption of the above structure, the present disclosure has the beneficial effects as follows:
1. base, 2. expansion bolt, 3. rotating shaft, 4. triangular supporting plate, 5. bearing, 6. rotating sleeve, 7. square connecting tube, 8. connecting plate, 9. bolt, 10. outer cylinder, 11. dumbbell placement plate, 12. placement groove, 13. decorative cover plate, 14. reinforcing plate, 15. rubber pad, 16. outer hoop, and 17. inner hoop.
The present disclosure is further described below in combination with the accompanying drawings.
In order to make the purposes, technical solutions and advantages of the present disclosure more clear, the present disclosure is further described in detail in combination with the accompanying drawings and specific embodiments below. It should be understood that the specific embodiments described herein are only used to explain the present disclosure, not to define the present disclosure.
Reference is made to
In this embodiment, a decorative cover plate 13 is arranged at the top of the outer cylinder 10. The top of the outer cylinder 10 is sealed by means of the decorative cover plate 13, and thus the attractiveness is improved.
In this embodiment, reinforcing plates 14 are further arranged at upper and lower ends between each of the groups of the dumbbell placement plates 11, which is conducive to the stability between each group of the dumbbell placement plates 11.
In this embodiment, a rubber pad 15 of an arc-shaped structure is sleeved on each of the placement grooves 12; therefore, on one hand, damage to the dumbbells is avoided, and on the other hand, noises produced when the dumbbells are placed are reduced.
In this embodiment, the base 1 is of a flower-shaped structure, which improves the attractiveness. The shape of the base 1 is not limited to the flower-shaped structure, and may be other shapes.
In this embodiment, the square connecting tubes 7 at the upper and lower ends of the rotating shaft 3 are distributed in a cross shape in space, which is conducive to the connection stability of the outer cylinder 10.
In this embodiment, the bearings 5 are fixed by means of outer hoops 16, and the bearings 5 are fixedly connected to the rotating sleeves 6 by means of inner hoops 17. Therefore, later maintenance and replacement of parts are facilitated.
The above description is only used to illustrate the technical solutions of the present disclosure, not to limit the present disclosure; and other modifications or equivalent replacements made by those of ordinary skill in the art on the technical solutions of the present disclosure should fall within the scope of claims of the present disclosure as long as such modifications or equivalent replacements do not deviate from the spirit and scope of the technical solutions of the present disclosure.
