Description
Technical field
The utility model relates to body-building apparatus technical field, is more particularly a kind of arm extension apparatus.
Background technology
Arm extension apparatus is the common body-building apparatus that frequency of utilization is higher, it is made up of column, crossbeam, rocking arm and tow handle; rocking arm rotates; tow handle realizes up-down alternative motion; thus user's upper limbs and shoulder back are taken exercise; and in order to reach good body-building effect, national regulation requires must carry out spacing by limited location device during swinging up and down of oscillating motion type sports apparatus.At present, existing spacing main employing be outside spacing, namely in two pipe supporting constructions, the gag lever post that restriction rocking arm rotation amplitude is excessive is provided with; play position-limiting action when rocking arm meets this device when rotating; although this structure limit effect is better; the noise produced is comparatively large, and affects attractive in appearance.
Summary of the invention
For solving the problem, the utility model devises a kind of inner spacing, the arm extension apparatus that noise is little, its technical scheme is: described arm extension apparatus comprises the two pipe supporting constructions fixed on the ground, be arranged on the crossbeam on two pipe supporting construction tops, crossbeam two ends are provided with rocking arm, rocking arm two ends are provided with tow handle, the two ends of described crossbeam and the junction of rocking arm are provided with stop, stop offers stopper slot, stop is provided with rotating shaft between two parties, one end of rotating shaft is fixedly connected with on the stopper, other end end face has screwed hole, the middle part of rocking arm is provided with bearing block, bearing sleeve is located at also phase countershaft rotation in rotating shaft, pair of bearings is provided with between bearing block and rotating shaft, outside framework oil seal is had in the arranged outside of bearing, stopper slot position on corresponding stop is fixedly connected with limit stick on bearing block, bearing block uses hex bolts to be fixed in rotating shaft.
Tow handle described in the utility model, it is characterized in that tow handle one end is provided with rubber handle, the other end is provided with mounting circular ring.
Rocking arm described in the utility model, it is characterized in that the two ends of rocking arm are provided with handle base, handle base is bolted mounting circular ring, and tow handle is rotatably mounted on rocking arm.
Limit stick described in the utility model, is characterized in that limit stick adopts polyurethane material to make.
The beneficial effects of the utility model arm extension apparatus are provided with stop and limit stick can play position-limiting action to rocking arm preferably, limit stick adopts polyurethane material to make, noise can be dropped to minimum time spacing, rotation place adopts bearing jointing structure simple, stable performance.
