Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, the technical scheme in this utility model embodiment is carried out clear, complete
Description, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.
Referring to Fig. 1～Fig. 2, a kind of chest expander, including two rectangular grip frames 2 with intermediate throughholes, difference
Two pulling force frames 3 being located at outside grip frame 2, one end connect the bullet that many spring drawstrings 5 of pulling force frame 3 are consistent with drawstring quantity
Spring 6 and every spring 6 of cladding prevent from crushing multiple protection sets 8 of skin.
The two ends symmetry of spring 6 connects spring drawstring 5.
Grip frame 2 includes for the first holding rod 21 of finger grip with for connecting the grip spring 22 of pulling force frame 3 and setting
The lead 23 being used for the first holding rod 21 is guided in both sides.
Pulling force frame 3 includes the second holding rod 31 for palm grip, is located at the strip corresponding with lead 23 of both sides
Pilot hole 32 (the most referring also to Fig. 1 and Fig. 2) and be located at the second holding rod 31 opposite side for installing spring drawstring 5
Multiple grooves 33.
Protection set 8 is the sleeve-like structure of the spring 6 for being coated with naturalness or elongation state.
Further, one end of arbitrary spring 6 is provided with and can detect spring 6 and extend the pulling force sensor 9 of deformation, pulling force frame
3 sides are provided with the processor electrically connected with pulling force sensor 9 for pulling force sensor 9 signal of telecommunication is converted into pulling force data
10, pulling force sensor 9 is other is provided with the report device 11 electrically connected with processor 10 that pulling force data carries out voice broadcast.
Further, spring 6 include cylinder spring body 61 and be located at two ends all with making the mild mistake of pulling force
The tapered portion 62 crossed.The two ends of spring 6 are equipped with tapered portion 62, and tapered portion 62 can be by the gently transition of the pulling force of spring body 61
To the spring drawstring 5 being connected with tapered portion 62, thus avoiding spring 6 end is the problem of stress concentration that cylindrical shape is brought, and increases
Add the protection to spring 6, and add safety coefficient.
Further, also include being located at two levers 1 for hands grasping at the second holding rod 31 two ends, connecting the other end
The second holding rod 31 two ends for coordinating lever 1 to carry out two pedals 7 of pedal action.Lever 1 is provided with projection, can keep away
