Describe embodiments of the invention in detail below in conjunction with accompanying drawing.
The structure-improved of locking mechanism between standpipe and adjustment pipe for a kind of fitness equipments provided by the present invention, standpipe 1 is freely inserted in to be adjusted in pipe 2, and by locking mechanism, standpipe 1 is fixed adjustment pipe 2 positions relatively, described locking mechanism comprises slide blocks 3, on adjustment pipe, offer the slip pipe moving freely for described slide blocks 3, described slide blocks 3 can be in described slip pipe axially moving freely along described slip pipe, another described slip pipe is opened on standpipe 1, and described slide blocks 3 be able to depart from and press on standpipe 1; Described slide blocks 3 comprises dead bolt 30 and briquetting 31, and described dead bolt 30 elastic telescopics are positioned the side of described briquetting 31 towards standpipe 1; Separately on the outer side wall of described dead bolt 30, axially form a ratchet face 10 along it at standpipe 1, described ratchet face 10 has some same oblique teeth notches, and described dead bolt 30 be able to depart from towards one end of standpipe 1 and only peak in the arbitrary teeth notch on ratchet face 10.
In the present embodiment, described slide blocks 3 can the structure axially moving freely along described slip pipe be in described slip pipe: described locking mechanism also comprises set lever 4, on described set lever and near the position of set lever one end, be articulated with on described slip pipe sidewall, described set lever offers curve bath 40 on one end, on described briquetting 31, be equipped with a straight pin 5, and 5 activities simultaneously of described straight pin wore described curve bath 40.The described briquetting 31 of the corresponding drive of rotation of described set lever 4 moves axially in described slip pipe, and described dead bolt 30 also moves axially in described slip pipe with described briquetting 31.
In the present embodiment, the structure being articulated with on described slip pipe sidewall on described set lever and near the position of set lever one end is: be also provided with a rotating shaft 6, on position on described set lever and near set lever one end, offer through hole 41, described rotating shaft 6 is positioned on described slip pipe and activity wore described through hole 41.
Also be provided with a countershaft pad 7, this countershaft pad 7 is positioned respectively the both sides of through hole 41 on described set lever, and described rotating shaft 6 is positioned on described slip pipe and fixedly wore this countershaft pad 7, and described rotating shaft 6 activities simultaneously wore described through hole 41.
In the present embodiment, on described briquetting 31, be equipped with a straight pin 5, and the described straight pin 5 simultaneously movable structure that wore described curve bath 40 is: described briquetting 31 offers opening-like locating slot 310 on the opposite side of described set lever 4 one end, and on the two opposite sides of described briquetting 31, all offering positioning through hole 311, described locating slot 310 is between this two positioning through hole 311; The curve bath 40 of described set lever 4 one end is movably placed in described locating slot 310, and described curve bath 40 also communicates with this two positioning through hole 311 respectively, and described straight pin 5 is located in this two positioning through hole 311 and activity wore described curve bath 40.
In the present embodiment, described dead bolt 30 elastic telescopics are positioned described briquetting 31: described briquetting 31 offers a positioning hole in a side of standpipe 1, described positioning hole communicates with described locating slot 310, also be provided with a spring 8, described spring 8 activities wore described positioning hole, and one end of described spring is relative with described position of positioning hole fixing, the other end of described spring and described dead bolt 30 are connected;
Described dead bolt 30 be able to depart from towards one end of standpipe 1 and the structure that only peaks in the arbitrary teeth notch on ratchet face 10 is: described dead bolt 30 forms a ramp structure towards one end of standpipe 1, teeth notch on this inclined-plane and described ratchet face matches, and this inclined-plane can depart from and locate in the arbitrary teeth notch being inserted on described ratchet face 10.
In the present embodiment, described slide blocks 3 also includes a pair of long strip limiting stopper 32, this is vertical and is fixed positioned in described briquetting 31 in a side of standpipe 1 long strip limiting stopper 32, described dead bolt 30 is movably placed in this between long strip limiting stopper 32, this can depart from and press on standpipe 1 long strip limiting stopper 32 under the effect of described briquetting 31, and this can locate adjusting to the distance between long strip limiting stopper 32 and described briquetting 31.
This structure that can locate adjusting to the distance between long strip limiting stopper 32 and described briquetting 31 is: on described briquetting 31, offer multiple the first tapped through holes, this is to offering respectively the second tapped through hole on long strip limiting stopper 32 and with described multiple the first tapped through hole opposite position places, also be provided with multiple screws 9, each screw 9 wore the first corresponding tapped through hole and the second tapped through hole successively, and each screw 9 can drive limiting stopper 32 relative risers corresponding thereto to do a little to move.
Mode of operation of the present invention is: rotation lock handle 4 the other ends, the set lever 4 corresponding rotations in one end, due to slide blocks 3 can be in slip pipe axially moving freely along slip pipe, therefore drive the rotation of curve bath 40 along with set lever 4 one end, curve bath 40 can pull or promote the corresponding court of straight pin 5 away from moving with close standpipe 1 direction, straight pin 5 drives briquetting 31 to do corresponding movement simultaneously, and therefore dead bolt 30 can corresponding loosen the active force to standpipe 1 or press on standpipe 1;
When set lever 4 the other ends are during in extreme higher position, this loosens the active force to standpipe 1 to long strip limiting stopper 32, and dead bolt 30 departs from the arbitrary teeth notch on ratchet face 10, and this serviceability lower standing tube 1 is adjusted the upper and lower free adjustment of pipe 2 positions relatively; And then, rotate set lever 4 the other ends, curve bath 40 promotes straight pin 5 towards moving near standpipe 1 direction, straight pin 5 drives briquetting 31 towards moving near standpipe 1 direction simultaneously, and set lever 4 one end also can drive dead bolt 30 towards moving near standpipe 1 direction by compressing spring 7, dead bolt 30 is inserted in the arbitrary teeth notch on ratchet face 10, but now this also keeps the relaxation state to standpipe 1 to long strip limiting stopper 32, due to the unidirectional motion effect of ratchet face, standpipe 1 can move up, but can not move down; And then continue to rotate set lever 4 the other ends, dead bolt 30 continues towards moving near standpipe 1 direction, until dead bolt 30 completely only peaks on ratchet face 10 in arbitrary teeth notch, and this presses on standpipe 1 long strip limiting stopper 32, now standpipe 1 is just upper and lower all can not move, and standpipe 1 is relatively adjusted pipe 2 positions and fixed.Therefore, this locking mechanism has three kinds of work gears, and it is easy to operate, and locking fastness is high.
In the present invention, between this is to limiting stopper 32 and described briquetting 31 and on described briquetting 31, the outer rim of positioning hole is all detachably installed with pad.Separately, in the time that this uses limiting stopper 32 is long-term, thereby this there will be fixing to standpipe position of wearing and tearing impact on limiting stopper 32 towards an end face of standpipe, now, only screw need be screwed into towards standpipe direction, promotes this limiting stopper 32 is advanced towards standpipe direction; When this is during to limiting stopper 32 serious wear, only need to change this to limiting stopper 32.
