The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, in order to address the above problem, the influence that the utility model provides the pulling force of body-building forearm flexor exerciser not increased and reduce simultaneously, can keep the spacing between the handgrip identical.
Body-building forearm flexor exerciser 1 overall appearance is as the hand vice shape, comprise medium frame plate 2, fixed cover 3, a left side, right holding rod 5,6, slide bar 8, spring 9, wherein, both sides, described fixed cover 3 upper end are connected and fixed by screw and described medium frame plate 2, also be provided with a regulating sleeve 4, has nut 10 in the described regulating sleeve 4, described regulating sleeve 4 is positioned at 3 sides under the described fixed cover, described spring 9 is sleeved on the body of rod 8-3 of described slide bar 8, the body of rod 8-3 lower end of described slide bar 8 has screw rod 8-1, described slide bar 8 upper ends are hinged end 8-2, the body of rod 8-3 part and the described spring 9 of described slide bar 8 are contained in described fixed cover 3 and the described regulating sleeve 4 formed cavitys, the screw rod 8-1 of described slide bar 8 is connected with the nut 10 of described regulating sleeve 4, the described hinged end 8-2 of described slide bar 8 is in the top of described fixed cover 3 top through holes, a described left side, right holding rod 5,6 lower ends are holding end, a described left side, right holding rod 5,6 upper ends are hinged end 5-1,6-1, described hinged end 5-1,6-1 has two pin joints, be side pin joint 5-2,6-2 and middle pin joint 5-3,6-3, a described left side, right holding rod passes through side pin joint 5-2 separately, 6-2 and described medium frame plate 2 are hinged, a described left side, right holding rod 5,6 middle pin joint 5-3, the described hinged end 8-2 of 6-3 and described slide bar 8 is hinged.
Described medium frame plate 2 is made of fronk rack plate 2-1 and back frame plate 2-2, and described forward and backward frame plate 2-1,2-2 connect by side swivel pin 2-5, the 2-6 of side pin joint, referring to Fig. 1.
In the cavity of the described hinged end 8-2 of described slide bar 8 between described forward and backward frame plate 2-1,2-2.
The described hinged end of described left and right holding rod 5,6 is made of forward and backward articulated slab, and promptly the front and back two boards constitutes, as the U-shaped shape.
Middle pin joint 5-3, the 6-3 of described left and right holding rod 5,6 are the strip hole, and bearing pin has certain activity like this, and the middle hinged end 8-2 that is beneficial to slide bar 8 moves up and down.
Described regulating sleeve and described nut are integral type, and intensity improves like this, are convenient to make.
For easy to adjust, the screw thread of described screw rod 8-1 is a steep-pitch thread.
For the ease of guiding person taking exercise's amplitude of exerting oneself, described fixed cover 3 is provided with the value of thrust scale, and is not shown.
Both sides, described medium frame plate 2 top inner face is confined planes 2-3,2-4, and described confined planes is the inclined-plane, the gradient on described inclined-plane for when left and right holding rod 5,6 against 2-3,2-4 when the described confined planes, left and right holding rod 5,6 is kept and the matched spacings of shoulder.
Spacing in the middle of the utility model handgrip is not subjected to the influence of the dynamics power of forearm flexor exerciser, remains equal spacing, and both hands firmly outwards draw back during exercise, overcome spring tension, and are reciprocal back and forth, thereby reaches the purpose of tempering arm and chest muscle.
During exercise, both hands firmly close up inwards, make left and right holding rod 5,6 middle pin joint 5-3,6-3 upwards draw the hinged end 8-2 of slide bar 8, slide bar 8 is when making progress, driving regulating sleeve 4 moves up, upwards compress spring 9 by regulating sleeve 4, spring 9 power are along with regulating sleeve 4 increase that moves up, thereby reach the purpose that exercises one's muscles.
Referring to Fig. 2, when rotary regulating sleeve 4, regulating sleeve 4 moves up, when not compressing spring 9, left and right holding rod 5,6 is in relaxed state, can transfer to amplitude peak, even the body of rod of left and right holding rod 5,6 is resisted against on confined planes 2-3, the 2-4 of medium frame plate 2, this amplitude and person taking exercise's shoulder width are about the same.
Referring to Fig. 3, when rotary regulating sleeve 4, regulating sleeve 4 moves up, when beginning to compress spring 9, impel slide bar 8 to move down, because the decrement of spring 9 is less relatively, thereby the amplitude that slide bar 8 moves down is little, the ultimate range that moves is that the body of rod of left and right holding rod 5,6 is resisted against on confined planes 2-3, the 2-4 of medium frame plate 2, at this moment, continue to rotate up regulating sleeve 4, can only increase the power width of cloth, can not enlarge the distance between the left and right holding rod 5,6, still keep constant with the matched spacing of shoulder.
This shows that the body-building forearm flexor exerciser that the utility model provides can keep an amount of spacing between the handgrip, the influence that is not subjected to pulling force to increase and reduce,
Above disclose only for a kind of preferred embodiment of the utility model, can not limit the interest field of the utility model certainly with this, therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
