Detailed description of the invention:
For clearly demonstrating the technical characterstic of this programme, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in Figure 1-2, a kind of dumbbell, comprise the first dumbbell bar 1 and the second dumbbell bar 2, one end at the first dumbbell bar 1 is provided with a thread groove along the length direction of the first dumbbell bar 1, the threaded one end of the second dumbbell bar 2 is arranged in thread groove, on the first dumbbell bar 1 and the second dumbbell bar 2, all movable sleeve is provided with 3, several dumbbells, be equipped with a fixture block 4 in the outer end of the first dumbbell bar 1 and the second dumbbell bar 2, on fixture block 4, be equipped with a fixture, described fixture comprises that one is located at the mounting box 5 on fixture block 4, in the inside of mounting box 5, a side is vertically provided with a take-up reel 6, take-up reel 6 is movably arranged on mounting box 5 one side inwalls by a horizontally disposed fixed axis 7, in mounting box 5, on the opposite side inwall relative with take-up reel 6, level is provided with a fixed bar 8, a spring mounting seat 9 relative with take-up reel 6 positions is connected on fixed bar 8, be provided with a mounting groove 10 at spring mounting seat 9 near a side of take-up reel 6, one is movably arranged in mounting groove 10 with one end of the rotating shaft 11 of the coaxial setting of fixed axis 7, the other end of rotating shaft 11 is connected mutually with the center of circle portion of take-up reel 6, one the inner that is arranged on the scroll spring 12 in mounting groove 10 is connected with rotating shaft 11, outer end is connected with the inwall of mounting groove 10, one one end and the take-up reel 6 that is wrapped in the fixed band 13 on take-up reel 6 is connected, the other end passes the outside of mounting box 5, be provided with a retainer ring 14 in the outer end of fixed band 13, two retainer rings 14 are set in respectively on the first dumbbell bar 1 and the second dumbbell bar 2, and two fixed bands 13 are tied up dumbbell plate 3 respectively solid on the first dumbbell bar 1 and the second dumbbell bar 2.
When use, in the time that people need to increase and decrease dumbbell plate 3, the second dumbbell bar 2 is backed out from the first dumbbell bar 1, the solid fixed band 13 in dumbbell plate 3 outsides is tied up in stretching, fixed band 13 drives take-up reel 6 to rotate, take-up reel 6 driven rotary axles 11 rotate, rotating shaft 11 drives coupled scroll spring 12 to tighten, in the time that fixed band is stretched to appropriate length, the retainer ring 14 being set on the first dumbbell bar 1 and the second dumbbell bar 2 is taken off, dumbbell plate 3 is set on the first dumbbell bar 1 or the second dumbbell bar 2 by the link of the first dumbbell bar 1 or the second dumbbell bar 2; Adjust after dumbbell plate 3, two fixed bands 13 stretch, two retainer rings 14 are set in respectively on the first dumbbell bar 1 and the second dumbbell bar 2, due to the effect that tightens of scroll spring 12, fixed band can the firm outside that must be bundled in dumbbell plate 3, avoid dumbbell plate 3 to rock in the process using, can use after the second dumbbell bar 2 again screw thread is arranged on the first dumbbell bar 1.
Adopt dumbbell of the present utility model, reasonable in design, in the time of increase and decrease dumbbell plate 3, dumbbell bar is split from middle part, increase and decrease from the middle part of dumbbell bar, operating process is simple, by fixed band, dumbbell plate is fixed, has avoided hold-down nut to fix and tightly do not occurred the situation that dumbbell plate 3 comes off, eliminated potential safety hazard.
The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
