For achieving the above object, the utility model has also proposed the winding roll of the adjustable wind spring the regulated intensity in a kind of outer ring, comprise rotating winding roll outer ring, dish axle, wind spring and winding roll inner ring, one end of described wind spring is fixed on the dish axle, the other end is fixed on the winding roll outer ring, described winding roll outer ring cooperates with the winding roll inner ring and forms inner chamber, and described wind spring places in the inner chamber, and the unidirectional rotation fixed structure of employing is connected between winding roll outer ring and the winding roll inner ring.
The beneficial effect of the utility model patent: the utility model is made as a circle in inner ring or the outer ring turnable, and an end of wind spring is fixed on the rotating circle, in user's use, when finding that wind spring elastic force reduces, but the circle that hand rotation can turn to makes behind its rotation certain distance fixing again, like this, the elastic force of wind spring has obtained enhancing again, and the take-up ability of whole winding roll is increased dramatically, and satisfies user's demand.The utility model is simple in structure, and cost is low, has prolonged the service life of winding roll.
[description of drawings]
Fig. 1 is the structural representation that the utility model can be regulated the winding roll of wind spring intensity;
Fig. 2 is that the winding roll that the utility model can be regulated wind spring intensity is ended the schematic diagram of the mated condition one of device and helical teeth;
Fig. 3 is that the winding roll that the utility model can be regulated wind spring intensity is ended the schematic diagram of the mated condition two of device and helical teeth;
Fig. 4 is that the winding roll that the utility model can be regulated wind spring intensity is ended the schematic diagram of the mated condition two of device and helical teeth.
[specific embodiment]
Embodiment one:
Shown in Fig. 1,2,3,4, can regulate the winding roll of wind spring intensity, comprise winding roll outer ring 1, dish axle 2, wind spring 3 and rotating winding roll inner ring 4, one end of described wind spring 3 is fixed on the dish axle 2, the other end is fixed on the winding roll inner ring 4, described winding roll outer ring 1 cooperates with winding roll inner ring 4 and forms inner chamber, and described wind spring 3 places in the inner chamber, and the unidirectional rotation fixed structure of employing is connected between winding roll outer ring 1 and the winding roll inner ring 4.Described unidirectional rotation fixed structure comprises being located at several helical teeth 5 that the circumferential hoop on the winding roll outer ring 1 establishes and being located at and ends device 6 on the winding roll inner ring 4 that the described device 6 that ends can snap in any one helical teeth 5, ends device 6 and is arranged on the winding roll inner ring 4 by spring 7.This is simple in structure, and it is convenient to realize.As conversion, also helical teeth 5 can be located on the winding roll inner ring 4, be located on the winding roll outer ring 1 and end device 6, can realize similar unidirectional rotation fixed effect.This structure is similar to the flywheel structure of bicycle, can only folk prescription to rotation.Operation for the convenience of the user, can adopt knob 8, described knob 8 is provided with at least two erection columns 81, have the installing hole 41 that cooperates with erection column 81 on the described winding roll inner ring 4, erection column 81 inserts and forms fixed structure in the installing hole 41, user's direct control knob 8 just can be realized rotating, thereby improves the elastic force of wind spring 3.
