Abstract
The invention discloses an improved connection structure for a pedal crank and a driving disc of body building equipment. The connection structure comprises a spindle and a flange based on a using direction, wherein one end of a right crank is detachably connected with the right end of the spindle in a rotation stopping mode, and the other end of the right crank is fixedly connected with a right pedal; and the flange is movably sleeved on one end of the right crank detachably connected to the spindle right end in a rotation stopping mode, and detachably and fixedly connected with the driving disc. Thus, welding spots do not exist between the flange and the spindle, so accidental rupture between the flange and the spindle does not exist; in addition, the flange is movably sleeved on one end of the right crank detachably connected to the spindle right end in a rotation stopping mode, the fixed connection mode is firmer than that for fixedly sleeving the flange on the spindle due to enlargement of a junction point, and the flange and one end of the right crank do not rupture; therefore, larger load can be borne by the flange, the phenomenon of rupture can be avoided, and the connection structure is safe and effective.
Description
Technical field
The present invention relates to a kind of body-building apparatus pedal crank and drive plate syndeton.
Background technology
At present, body-building apparatus is installed in the end, axle center with the detachable spline of pedal crank, ring flange is fixed sheathed being welded on the axle center, ring flange is removably fixed with on drive plate by screw again, the fixing position load of axle center and ring flange is larger like this, so that described fixing position ruptures easily, thus the security incident of causing.
Summary of the invention
In order to overcome defects, the invention provides the structure-improved that a kind of body-building apparatus is connected with drive plate with pedal crank, the structure-improved that this body-building apparatus is connected with drive plate with pedal crank can make and bear larger load between axle center and the ring flange, the phenomenon of fracture can not occur, and is safe and effective.
The present invention for the technical scheme that solves its technical problem and adopt is: the structure-improved that a kind of body-building apparatus is connected with drive plate with pedal crank, to use direction as benchmark, comprise axle center and ring flange, right crank one end is connected with the detachable spline of axle center right-hand member, the right crank other end and right step are affixed, ring flange is movably set on the axle center, and ring flange and the detachable spline of right crank are connected in an end affixed (this example is welding) of axle center right-hand member, and ring flange is removably fixed with in drive plate.
Further technical scheme of the present invention is:
Ring flange is removably fixed with in the structure of drive plate: evenly be provided with several perforation on the ring flange, be provided with some screws, described screw correspondence is passed perforation and is fixed on the drive plate.
Right crank one end with the structure that right-hand member detachable spline in axle center is connected is: axle center right-hand member radial section is regular hexagon; right crank one end is provided with the regular hexagon hole; described regular hexagon hole just can be sheathed on radial section and be orthohexagonal axle center right-hand member; certainly also have other various appearance; being the continuous formation of some arcs etc. such as axle center right-hand member radial section, all is this routine claimed scope.
Drive plate is a kind of in belt pulley and the toothed disc.
The invention has the beneficial effects as follows: because ring flange is movably set on the axle center, ring flange and the detachable spline of right crank are connected in an end affixed (this example is welding) of axle center right-hand member, ring flange is removably fixed with in drive plate, there is not like this solder joint between ring flange and the axle center, so there is not accident fracture between the two, ring flange is fixed in the end that the detachable spline of right crank is connected in the axle center right-hand member again, increase because of the abutment, so that this affixed mode is more firm than the affixed mode that ring flange is placed in the axle center admittedly, ring flange can not rupture with right crank one end, therefore this example can make ring flange bear larger load, the phenomenon of fracture can not appear, and safe and effective.
Description of drawings
Fig. 1 is exploded view of the present invention.
Among Fig. 1, the 1-crank cap; 2-crank screw; The left crank of 3-; 4-frame five-through pipe; The 5-axis; The 6-drive plate; The right crank of 7-.
The specific embodiment
Embodiment: the structure-improved that a kind of body-building apparatus is connected with drive plate with pedal crank, to use direction as benchmark, comprise axle center 9 and ring flange, right crank 7 one ends are connected with the detachable spline of axle center right-hand member, the right crank other end and right step are affixed, ring flange 8 is movably set on the axle center, and ring flange and the detachable spline of right crank are connected in an end affixed (this example is welding) of axle center right-hand member, and ring flange is removably fixed with in drive plate 6.
Ring flange is removably fixed with in the structure of drive plate: evenly be provided with several perforation on the ring flange, be provided with some screws, described screw correspondence is passed perforation and is fixed on the drive plate.
Right crank one end with the structure that right-hand member detachable spline in axle center is connected is: axle center right-hand member radial section is regular hexagon; right crank one end is provided with the regular hexagon hole; described regular hexagon hole just can be sheathed on radial section and be orthohexagonal axle center right-hand member; certainly also have other various appearance; being the continuous formation of some arcs etc. such as axle center right-hand member radial section, all is this routine claimed scope.
Drive plate 6 is a kind of in belt pulley and the toothed disc.
The same spline of this routine left crank is connected in the axle center left end, is prior art, and this example no longer describes in detail, and and for example ring flange, drive plate are arranged on the body-building apparatus left side, then can adopt equally this routine structure, is all this routine claimed scope.
