Description
Technical field
The present invention relates to a kind of scooters, and in particular to a kind of scooter standpipe telescopic device.
Background technique
The telescopic sleeve of current luggage standpipe stretching structure is positioned essentially by single hoodle location structure, single at present
Not only structure is complicated for hoodle location structure, at high cost, but also there is a problem of that position stability and safety are bad, and then influence
The safety in utilization of scooter.
Summary of the invention
It is simple, at low cost that the purpose of the present invention is to overcome the shortcomings in the prior art and to provide a kind of structures, and
And positioning stablity, safe and reliable scooter standpipe telescopic device.
The technical scheme is that
A kind of scooter standpipe telescopic device further includes double including main casing and the standpipe being slidably arranged in main casing
Ball bead type standpipe positioning mechanism, double ball bead type standpipe positioning mechanisms include the pin shaft being arranged in standpipe lower part, hang on pin shaft
Inverted V-shaped elastic slice, be slidably arranged in standpipe and be located above inverted V-shaped elastic slice elastic slice briquetting, be arranged under the side of standpipe

The section in face is that involute circular arc (refers to section perpendicular with articulated shaft towards the section of the lateral surface of the lock handle of clamping sleeve
Face).
The scooter standpipe telescopic device of the present embodiment it is specifically used as follows:
It is realized by rotation lock handle and compresses standpipe or unclamp standpipe, up rotate lock handle, clamping sleeve unclamps
Standpipe；When rotation lock handle compresses down, since the section of the lateral surface of the lock handle towards clamping sleeve is involute circle
Arc, thus lock handle can tightly suppress standpipe by clamping sleeve, standpipe is in the lock state with main casing at this time.
When standpipe needs to elongate or shorten:
Lock handle is up rotated, clamping sleeve is made to unclamp standpipe；
Then, elastic press is pressed down, makes the positioning pin of inverted V-shaped elastic slice toward inside contracting by elastic press, to make to determine
Position pin is separated with the casing location hole of main casing, and standpipe can the smooth sliding in main casing at this time；
Followed by, standpipe is up pulled or moved down, until positioning pin is ejected into the casing positioning hole of main casing,
To realize elongating or shortening for standpipe；Double ball bead type standpipe positioning mechanisms of the present embodiment fall V by two detent fits
Shape elastic slice is positioned, and can effectively improve the position stability and security reliability of standpipe telescopic device, and structure is simple；
Finally, rotation lock handle compresses down, standpipe is tightly suppressed by lock handle, standpipe and main casing is made to be in lock
Determine state.
Pass through above-mentioned action process: making telescopic sleeve and main riser specific elongation or shorten to reach slide board handle height
Conversion between position, so that achieving the effect that scooter is convenient to use facilitates collection again.
