Abstract
The utility model discloses a pull rod returns device that contracts for rowing boat machine, a pull rod returns device that contracts for rowing boat machine contain a rotation portion and a supporting part, the supporting part with rotation portion between be equipped with the wind spring that resets. The utility model discloses a pull rod returns device that contracts for rowing boat machine's advantage is: during the use, the pull rod afterbody of the machine of rowing the boat is connected with a carousel, and this carousel snap -on is in the pivot of rotation portion. When the carousel rotated, rotation portion can drive the wind spring that resets for deformation takes place for the wind spring that resets, after the user releases the pull rod, and under the effect of the wind spring that resets, the rotation that resets of rotation portion, the person of facilitating the use continues to stimulate the pull rod, thereby rows the boat the exercise repeatedly. Since adopt the built -in wind spring that resets, the drive reinforce, the restoring force is big, and difficult emergence is tired, has prolonged the life of the machine of rowing the boat greatly, and the practicality is strong.
Description
Technical field
The utility model relates to a kind of sports equipment, or rather, is a kind of pull bar restoring device for rowing machine.
Background technology
Rowing machine is a kind of common physical fitness equipment, and user performs physical exercise by simulating the action of rowing the boat.The pull bar afterbody of existing rowing machine is resetted by linear springs, easily tired, affects the result of use of rowing machine.
Utility model content
The utility model mainly solves the technical problem existing for prior art, thus provides a kind of pull bar restoring device for rowing machine.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of pull bar restoring device for rowing machine, the described pull bar restoring device for rowing machine comprises a rotation section and a support portion, a reset wind spring is provided with between described support portion and described rotation section, described rotation section comprises a discoid rolling disc, the center of described rolling disc is provided with a columned rotating shaft, the sidewall of described rotating shaft is provided with a positioning screw hole, the top of described rotating shaft is provided with the card seam of a yi word pattern, the head of described rotating shaft is provided with a coupling nut, described rotating shaft runs through described reset wind spring, the center of described reset wind spring is embedded in described card seam, described support portion comprises the support cylindrical shell of a discoid support disk body and a cylindrical shape, the sidewall of described support disk body is provided with a positioning round orifice, described support cylindrical shell is provided with a spring bearing, one lock bolt runs through described positioning round orifice and positioning screw hole respectively.
As the utility model preferred embodiment, described rotation section and support portion are steel casting.
The advantage of the pull bar restoring device for rowing machine of the present utility model is: during use, and the pull bar afterbody of rowing machine is connected with a rotating disk, and this rotating disk is directly fixed in the rotating shaft of rotation section.When dial rotation, rotation section can drive reset wind spring, makes reset wind spring generation deformation, and after user discharges pull bar, under the effect of reset wind spring, rotation section resets and rotates, and person easy to use continues to pull pull bar, thus repeatedly carries out outing.Owing to adopting built-in reset wind spring, driving force is strong, and restoring force is large, not easily fatigue occurs, substantially prolongs the service life of rowing machine, practical.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
As shown in Figures 1 to 5, this pull bar restoring device 1 being used for rowing machine comprises rotation section 2 and a support portion 3, a reset wind spring 6 is provided with between this support portion 3 and this rotation section 2, this rotation section 2 comprises a discoid rolling disc 21, the center of this rolling disc 21 is provided with a columned rotating shaft 23, the sidewall of this rotating shaft 23 is provided with a positioning screw hole 24, the top of this rotating shaft 23 is provided with the card seam 25 of a yi word pattern, the head of this rotating shaft 23 is provided with a coupling nut 22, this rotating shaft 23 runs through this reset wind spring 6, the center of this reset wind spring 6 is embedded in this card seam 25, this support portion 3 comprises the support cylindrical shell 32 of a discoid support disk body 31 and a cylindrical shape, the sidewall of this support disk body 31 is provided with a positioning round orifice 33, this support cylindrical shell 32 is provided with a spring bearing 4, one lock bolt 5 runs through this positioning round orifice 33 and positioning screw hole 24 respectively.
This rotation section 2 and support portion 3 are steel casting.
During use, as depicted in figs. 1 and 2, the pull bar afterbody of rowing machine is connected with a rotating disk, and this rotating disk is directly fixed in the rotating shaft 23 of rotation section 2.When dial rotation, rotation section 2 can drive reset wind spring 6, makes reset wind spring 6 that deformation occur, and after user discharges pull bar, under the effect of reset wind spring 6, rotation section 2 resets and rotates, and person easy to use continues to pull pull bar, thus repeatedly carries out outing.Owing to adopting built-in reset wind spring 6, driving force is strong, and restoring force is large, not easily fatigue occurs, substantially prolongs the service life of rowing machine, practical.
Be not limited to this, any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
