Principle of work of the present utility model is as described below:
Telescopic tube assembly locking: when telescopic pipe was opened fully, elementary ripple pearl was stuck in the corresponding perforate with the first intermediate ripple pearl, the locking that is opened of the flexible trombone slide of elementary flexible trombone slide and middle rank; When needing to shrink telescopic tube assembly, press the button switch, button switch drives drive spindle by depression bar and moves down, the collision block of drive spindle lower end clashes into the elementary lock pin of elementary tube wave pearl lockout mechanism thereupon, elementary lock pin compresses elementary spring and moves down, because evagination down on the cascaded surface of elementary lock pin is served as reasons, therefore in elementary lock pin folding process, elementary ripple pearl has just had the gap that retreats, thereby withdraw from corresponding perforate, elementary flexible trombone slide loses the locking action of elementary tube wave pearl lockout mechanism, can smooth and easyly move down; In like manner, the shrinkage operation of the flexible trombone slide of middle rank is also as elementary flexible trombone slide; When the flexible trombone slide of elementary flexible trombone slide and middle rank is displaced downwardly to the fixed sleeving bottom, the intermediate lock contact of middle rank tube wave pearl lockout mechanism stops to move down to the interior connecting element of fixed sleeving, at this moment, because second cascaded surface of intermediate lock pin is indent from top to bottom, therefore, can expose intermediate lock with the second intermediate ripple pearl of second cascaded surface contact blocks with corresponding perforate, thereby with fixed sleeving and the flexible trombone slide locking of middle rank, in like manner the flexible trombone slide of middle rank and elementary flexible trombone slide can be locked, thereby the trombone slide assembly that will stretch shrinks locking.
Telescopic tube assembly release: when needing release to stretch the trombone slide assembly, press the button switch, button switch drives drive spindle by depression bar and moves down, the collision block of drive spindle lower end drives elementary lock pin and moves down, because evagination down on the cascaded surface of elementary lock pin is served as reasons, therefore in elementary lock pin folding process, elementary ripple pearl has just had the gap that retreats, thereby withdraw from the perforate of the flexible trombone slide lower end of corresponding middle rank, elementary flexible trombone slide can stretch out, afterwards, because intermediate lock pin loses the contact effect of elementary lock, under the effect of intermediate spring restoring force, intermediate lock pin can on move, the second intermediate ripple pearl withdraws from corresponding perforate thereupon, the flexible trombone slide of middle rank also can stretch out, because the upper edge hole place of the flexible trombone slide of middle rank and fixed sleeving is provided with fixed cover respectively, the bottom outer wall of elementary flexible trombone slide and the flexible trombone slide of middle rank is respectively arranged with the locating bush with the fixed cover close-fitting, therefore flexible trombone slide assembly can not produce the situation of rocking when launching or shrink, solid and reliable.
The synchronization action of castor and loading plate: revolve mechanism because the contact position of loading plate and castor is provided with pendulum, therefore, loading plate fold or expansion process in, can drive castor synchronously and draw in or open, convenient and swift.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or modification are not broken away from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and modification.
