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 sports equipment, more precisely, a pull rod retraction device for rowing machine.
Background
A rowing machine is a common physical fitness apparatus, and a user exercises by simulating a rowing motion. The pull rod afterbody of current rowing machine resets through linear spring, and is tired easily, influences rowing machine's result of use.
SUMMERY OF THE UTILITY MODEL
The utility model discloses solve the technical problem that prior art exists to a pull rod that is used for rowing machine returns and contracts device is provided.
The above technical problem of the present invention can be solved by the following technical solutions:
a pull rod retraction device for a rowing machine comprises a rotating part and a supporting part, a reset coil spring is arranged between the supporting part and the rotating part, the rotating part comprises a disk-shaped rotating disk, a cylindrical rotating shaft is arranged at the center of the rotating disc, a positioning screw hole is arranged on the side wall of the rotating shaft, the top of the rotating shaft is provided with a straight-line-shaped clamping seam, the head of the rotating shaft is provided with a connecting screw cap, the rotating shaft penetrates through the reset coil spring, the center of the reset coil spring is embedded in the clamping slot, the supporting part comprises a disc-shaped supporting disc body and a cylindrical supporting cylinder body, a positioning round hole is arranged on the side wall of the supporting disc body, the supporting cylinder is provided with a supporting bearing, and a locking screw penetrates through the positioning round hole and the positioning screw hole respectively.
As the preferred embodiment of the utility model, the rotating part and the supporting part are steel castings.
The utility model discloses a pull rod that is used for rowing machine contracts device's advantage is: when in use, the tail part of the pull rod of the rowing machine is connected with a rotary disk, and the rotary disk is directly fixed on a rotary shaft of the rotary part. When the carousel rotated, the rotation portion can drive the spring that restores to the throne for the spring that restores to the throne takes place deformation, and after the user released the pull rod, under the effect of the spring that restores to the throne, the rotation portion resets and rotates, and convenience of customers continues to stimulate the pull rod, thereby carries out the exercise of rowing boat repeatedly. Because the built-in reset coil spring is adopted, the driving force is strong, the restoring force is large, the fatigue is not easy to occur, the service life of the rowing machine is greatly prolonged, and the practicability is strong.

Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.
As shown in fig. 1 to 5, the drawbar retracting device 1 for a rowing machine includes a rotating part 2 and a supporting part 3, a return coil spring 6 is provided between the support portion 3 and the rotation portion 2, the rotation portion 2 includes a disk-shaped rotation disk 21, a cylindrical rotating shaft 23 is arranged at the center of the rotating disc 21, a positioning screw hole 24 is arranged on the side wall of the rotating shaft 23, the top of the rotating shaft 23 is provided with a linear clamping slot 25, the head of the rotating shaft 23 is provided with a connecting nut 22, the rotation shaft 23 penetrates the return coil spring 6, the center of the return coil spring 6 is inserted into the catching slit 25, the support portion 3 includes a disc-shaped support plate 31 and a cylindrical support cylinder 32, a positioning round hole 33 is formed on the side wall of the supporting disk body 31, a supporting bearing 4 is arranged on the supporting cylinder body 32, and a locking screw 5 respectively penetrates through the positioning round hole 33 and the positioning screw hole 24.
The rotating part 2 and the supporting part 3 are both steel castings.
In use, as shown in figures 1 and 2, the tail of the lever of the rowing machine is connected to a turntable which is directly fixed to the shaft 23 of the rotating part 2. When the carousel rotated, rotation portion 2 can drive reset coil spring 6 for reset coil spring 6 takes place deformation, after the user releases the pull rod, under reset coil spring 6's effect, rotation portion 2 resets and rotates, and the person of facilitating the use continues the pulling pull rod, thereby carries out the exercise of rowing boat repeatedly. Because the built-in reset coil spring 6 is adopted, the driving force is strong, the restoring force is large, the fatigue is not easy to occur, the service life of the rowing machine is greatly prolonged, and the practicability is strong.
