Description
Technical field
The utility model belongs to the body-building apparatus technical field, the seat of a kind of body-building apparatus of more clearly saying so, back cushion height arm control.
Background technology
Seat cushion or back cushion generally all are installed on the large and medium-sized body-building apparatus, even existing seat cushion also there is back cushion, uses by, pad when in place for the body builder.Because body builder's stature, limbs each several part length, age, angle out of strength and intensity or the like is different, the height of seat, back cushion also just should be different.In order to adapt to different body builders' different needs, the seat of body-building apparatus, the height of back cushion also just need often to adjust.
Existing body-building apparatus, be mostly be present, the seat pipe of back cushion goes up and makes row's pin-and-hole, makes a pin-and-hole on the standpipe of its pedestal, latch inserts in the different holes of standpipe, seat, back cushion just have different height.This method of adjustment is more complicated.Each height of adjusting depends on pitch-row thereby bigger, and adjustable progression is less, only coarse adjustment.In addition, latch is easily lost, thereby convenient inadequately.
The purpose of this utility model is to overcome above-mentioned shortcoming and defect, provides a kind of adjusting more convenient, light and handy; Adjustable progression is more, to adapt to different body builders' different needs better; Do not need latch, thereby can not lose seat, the back cushion height arm control of the body-building apparatus that brings inconvenience yet.
Summary of the invention
In order to achieve the above object, the utility model is made of seat board on the seat pipe in the standpipe that is inserted into the body-building apparatus pedestal, the fixing present pipe and the guiding mechanism that is installed on it.Guiding mechanism by be fixed on vertical tube below the seat board, be fixed on vertical sour jujube bar on the vertical tube, be fixed on the standpipe of pedestal and the front have the guide pin bushing of vertical tube leading arm, be fixed on the standpipe of pedestal and have axis hole ratchet holder, with little axle be installed on the ratchet holder and have alignment pin ratchet, be fixed on the spring(-supported) mount on the standpipe of pedestal and be installed in ratchet and spring(-supported) mount between the compression spring constituted.
Vertically the upper end of sour jujube bar has the ratchet overhead gage, deviates from from vertical sour jujube bar to prevent ratchet, limits its tip position.
During use, seat, back cushion are pulled upwardly gently together with its seat board, seat pipe, vertical tube just can rise from the guide pin bushing of leading arm, drives vertical sour jujube bar and rises.Vertically the elastic force that just overcomes the compression spring of the ratchet on the sour jujube bar jack-up ratchet that makes progress makes ratchet enter next ratchet, until reaching the height that needs.When the body builder sat down, the alignment pin of ratchet was stuck on the ratchet holder, and ratchet blocks ratchet, and it can not be fallen, and it is firm to locate.
Task of the present utility model comes to this and finishes.
The utility model provides a kind of adjusting more convenient, light and handy, and adjustable progression is more, to adapt to different body builders' different needs better, does not need latch, thereby also can not lose seat, the back cushion height arm control of the body-building apparatus that brings inconvenience.It can be widely used in the various body-building apparatus.
