Detailed description of the invention
Embodiments of the invention are described in detail below in conjunction with accompanying drawing.
The structure-improved of retaining mechanism between a kind of body-building apparatus standpipe provided by the present invention and adjustment pipe, standpipe 1 is certainly
By being inserted in adjustment pipe 2, and making standpipe 1 relatively adjust pipe 2 position by retaining mechanism to fix, described retaining mechanism includes cunning
Motion block 3, adjusts and offers the slip pipe moved freely for described sliding shoe 3 on pipe, described sliding shoe 3 can in described slip pipe edge
Being free to move axially of described slip pipe, another described slip pipe is opened on standpipe 1, and described sliding shoe 3 be able to depart from and press on vertical
Pipe 1；Described sliding shoe 3 includes that dead bolt 30 and briquetting 31, described dead bolt 30 elastic telescopic are positioned described briquetting 31 towards standpipe 1
Side；Separately being axially formed a ratchet face 10 along it at standpipe 1 on the lateral wall of described dead bolt 30, described ratchet face 10 has
Having some same oblique teeth notches, described dead bolt 30 be able to depart from towards one end of standpipe 1 and only peak at ratchet face 10
On arbitrary teeth notch in.
In the present embodiment, described sliding shoe 3 can be along the knot being free to move axially of described slip pipe in described slip pipe
Structure is: described retaining mechanism also includes set lever 4, is articulated with on described set lever and near the position of set lever one end
On described slip pipe sidewall, described set lever one end offers arcuate groove 40, described briquetting 31 is equipped with a straight pin 5,
And activity is fed through described arcuate groove 40 while of described straight pin 5.The rotation correspondence of described set lever 4 drives described briquetting 31
Described slip pipe moves axially, and described dead bolt 30 also moves axially with described briquetting 31 in described slip pipe.
In the present embodiment, the position of on described set lever and close set lever one end is articulated with described slip pipe sidewall
On structure be: be additionally provided with a rotating shaft 6, on described set lever and near set lever one end position on offer through hole
41, described rotating shaft 6 is positioned on described slip pipe and activity is fed through described through hole 41.
Being additionally provided with a countershaft pad 7, this countershaft pad 7 is respectively positioned in the both sides of through hole 41 on described set lever, institute
State rotating shaft 6 to be positioned on described slip pipe and fixing this countershaft pad 7 that is fed through, and described rotating shaft 6 activity simultaneously is fed through described
Through hole 41.
In the present embodiment, described briquetting 31 is equipped with a straight pin 5, and described straight pin 5 activity simultaneously is fed through
The structure of described arcuate groove 40 is: described briquetting 31 is opening-like towards offering on the side of described set lever 4 one end
Locating slot 310, and on the two opposite sides of described briquetting 31, all offer positioning through hole 311, it is fixed that described locating slot 310 is positioned at two
Between the through hole 311 of position；The arcuate groove 40 of described set lever 4 one end is movably placed in described locating slot 310, described arcuate groove
40 communicate with two positioning through hole 311 the most respectively, and described straight pin 5 is located in two positioning through hole 311 and activity is fed through described
Arcuate groove 40.
In the present embodiment, described dead bolt 30 elastic telescopic is positioned the described briquetting 31 structure towards the side of standpipe 1
For: described briquetting 31 offers a hole, location on the side of standpipe 1, and hole, described location communicates with described locating slot 310, also
Being provided with a spring 8, the activity of described spring 8 is fed through hole, described location, and one end of described spring and described position of positioning hole phase
To fixing, the other end of described spring is connected with described dead bolt 30；
Described dead bolt 30 be able to depart from towards one end of standpipe 1 and only peak on ratchet face 10 arbitrary teeth notch in
Structure be: described dead bolt 30 forms a ramp structure towards one end of standpipe 1, the teeth groove on this inclined-plane and described ratchet face
Mouth matches, and this inclined-plane can depart from and position in the arbitrary teeth notch being inserted on described ratchet face 10.
In the present embodiment, described sliding shoe 3 also includes a pair strip limited block 32, and this is to strip limited block 32
In vertical and be fixed positioned in described briquetting 31 towards on the side of standpipe 1, described dead bolt 30 is movably placed in this and limits strip
Between the block 32 of position, this can depart from and press on standpipe 1 to strip limited block 32 under the effect of described briquetting 31, and this is right
Distance between strip limited block 32 and described briquetting 31 can position regulation.
This structure that distance between strip limited block 32 and described briquetting 31 can position regulation is: described briquetting
Offering multiple first tapped through hole on 31, this is on strip limited block 32 and corresponding with the plurality of first tapped through hole
Position offers the second tapped through hole respectively, is additionally provided with multiple screw 9, and each screw 9 is fed through the first corresponding spiral shell successively
Stricture of vagina through hole and the second tapped through hole, and each screw 9 can drive strip limited block 32 relative riser corresponding thereto to do micro-
Amplitude shift is moved.
The mode of operation of the present invention is: rotation lock handle 4 other end, and set lever 4 one end rotates accordingly, owing to sliding
Block 3 can in slip pipe being free to move axially along slip pipe, therefore along with set lever 4 one end drive arcuate groove 40 rotation,
Arcuate groove 40 can pull or promote the corresponding court of straight pin 5 to move away from near standpipe 1 direction, and straight pin 5 drives simultaneously
Briquetting 31 does corresponding mobile, and therefore dead bolt 30 corresponding can loosen the active force to standpipe 1 or press on standpipe 1；
When set lever 4 other end is in extreme higher position, strip limited block 32 is loosened the effect to standpipe 1 by this
Power, dead bolt 30 departs from the arbitrary teeth notch on ratchet face 10, this mode of operation lower standing tube 1 relatively adjust pipe 2 position upper,
Lower freely regulate；And then, rotating down set lever 4 other end, arcuate groove 40 promotes straight pin 5 towards near standpipe 1 direction
Mobile, straight pin 5 drives briquetting 31 to move towards near standpipe 1 direction simultaneously, and set lever 4 one end also can be by compressing bullet
Spring 7 drives dead bolt 30 to move towards near standpipe 1 direction, in arbitrary teeth notch that dead bolt 30 is inserted on ratchet face 10, but this
Time strip limited block 32 is also continued to be in the relaxation state to standpipe 1 by this, due to the unidirectional motion effect of ratchet face, vertical
Pipe 1 can move up, but can not move down；Then being further continued for rotating down set lever 4 other end, dead bolt 30 continues
Moving towards near standpipe 1 direction, until dead bolt 30 the most only peaks on ratchet face 10 in arbitrary teeth notch, and this is to strip
Limited block 32 presses on standpipe 1, and now standpipe 1 is the most upper and lower all can not move, and standpipe 1 relatively adjusts pipe 2 position and fixes.
Therefore, this retaining mechanism has three kinds of operation range, and it is easy to operate, and locking firmness is high.
In the present invention, position between strip limited block 32 and described briquetting 31 and on described briquetting 31 at this
The outer rim in hole is the most detachably installed with pad.Separately, when this is to strip limited block 32 life-time service, this is to strip limited block
32 there will be abrasion towards the end face of standpipe thus standpipe position fix by impact, now, and need to be by screw towards standpipe side
To being screwed into, promote this that strip limited block 32 is advanced towards standpipe direction；When this is to strip limited block 32 serious wear
Time, only need to change this to strip limited block 32.
