Abstract
The utility model discloses a locking mechanism improvement for a stand pipe and an adjusting pipe used for bicycles and fitness equipment. The stand pipe is freely inserted in the adjusting pipe; the positions of the stand pipe and the adjusting pipe are relatively fixed through the locking mechanism; a sliding block and a quick-release handle are arranged; a sliding pipe for the sliding block to move freely is arranged on the adjusting pipe; the sliding block in the sliding pipe can move axially and freely along the sliding pipe; the sliding pipe has an opening at the stand pipe; the sliding block can properly butt or release the stand pipe; an arc groove is formed at one end of the quick-release handle; a positioning pin is arranged on the sliding block and movably passes through the arc groove; the part between the other end of the quick-release handle and the arc groove is pivoted with a lateral wall of the sliding pipe; and the distance from the part to the arc groove is smaller than the distance from the part to the other end of the quick-release handle, therefore, the pivoting part is taken as a pivot point, the lever principle is formed, a worker can pull the other end of the quick-release handle with less effort, and the stand pipe locking operation is facilitated. The utility model is convenient to operate, the locking firmness is high, and the locking state can be kept for a long time.
Description
Technical field
The utility model relates to a kind of bicycle, body-building apparatus standpipe and the catch gear of adjusting pipe.
Background technology
At present, bicycle, the standpipe that body-building apparatus is used relates generally to handlebar and seat cushion place with the adjustment pipe, height as handlebar is regulated, it is exactly by on the standpipe that the height of seat cushion is regulated, following adjustment realizes, known standpipe and the fixing and locking mechanism of adjusting between the pipe are the bolts of band lever, rotation by bolt presses closer standpipe and realizes and adjust stationkeeping between the pipe, right this locking mode uses the back bolt to take place loosening easily for a long time and causes standpipe loosening, thereby the safety misadventure of causing, locking face less (only being the bolt end) again, Suo Jin firmness is not high like this, locks or loosen standpipe time operation trouble again.
The utility model content
In order to overcome above-mentioned defective, the utility model provides a kind of bicycle, body-building apparatus with standpipe and the improved locking mechanism of adjusting pipe, and this improved locking mechanism is easy to operate, the firmness of locking is high and can maintain the lock status for a long time.
The utility model for the technical scheme that solves its technical matters and adopt is:
A kind of bicycle, body-building apparatus standpipe and the improved locking mechanism of adjusting pipe, standpipe freely is inserted in to be adjusted in the pipe, make standpipe and the position relative fixed of adjusting pipe by catch gear, be provided with sliding shoe and quick detach handle, adjust pipe and be provided with the slip pipe that moves freely for sliding shoe, sliding shoe can be along axially the moving freely of slip pipe (being that sliding shoe can not detach slip pipe) in slip pipe, slip pipe is opened on standpipe, sliding shoe just can push against and unclamp standpipe, one end of quick detach handle is provided with deep-slotted chip breaker, sliding shoe is provided with (fixed or movable can) locating dowel pin, locating dowel pin activity simultaneously wore described deep-slotted chip breaker, position between the quick detach handle other end and the deep-slotted chip breaker is articulated on the slip pipe sidewall, described position less than the distance from the quick detach handle other end, is a fulcrum to articulate the position from the distance of deep-slotted chip breaker like this, forms lever principle, more laborsaving when personnel pull the quick detach handle other end, be beneficial to the locking standpipe.
The centre of described sliding shoe is provided with the positioning groove that is opening towards quick detach handle one end, the both sides of described sliding shoe are provided with positioning through hole, described positioning groove is between the positioning through hole of both sides, the deep-slotted chip breaker of quick detach handle one end is movably placed in the described positioning groove, described deep-slotted chip breaker communicates with described positioning through hole, described locating dowel pin wear (can be fixed or movable) in two positioning through hole and activity wore deep-slotted chip breaker.
The structure that position between the described quick detach handle other end and the deep-slotted chip breaker is articulated on the slip pipe sidewall is: be provided with the lock bolt, described position is provided with through hole, describedly is positioned on the slip pipe and activity wore described through hole to the lock bolt.
The beneficial effects of the utility model are: this routine course of action is: when upwards rotating when the contrary direction of arrow shown in Figure 1 of the quick detach handle other end, quick detach handle one end rotates, because sliding shoe axially moves in slip pipe only, drive the rotation of deep-slotted chip breaker along with quick detach handle one end, deep-slotted chip breaker pulling locating dowel pin is towards moving away from the standpipe direction, thereby make sliding shoe towards moving away from the standpipe direction, sliding shoe loosens the application force to standpipe, gets final product the position that upper and lower adjusting standpipe is adjusted pipe relatively like this; After the standpipe position adjustments is appropriate, the quick detach handle other end is rotated along the direction of arrow shown in Figure 1, quick detach handle one end upwards rotates, deep-slotted chip breaker promotes locating dowel pin towards moving near the standpipe direction, thereby make sliding shoe press standpipe towards moving near the standpipe direction, the standpipe position of adjusting pipe has relatively just been fixed like this.Can find out that therefrom this example is to press and unclamp standpipe by sliding shoe, locking face is bigger like this, the firmness height of locking, and the operation that moves through the quick detach handle of sliding shoe realizes, and is easy to operate like this and can maintain the lock status for a long time.
