Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in figures 1-8, child's tricycle steering lock mechanism of the present utility model, comprise locking seat 3, be positioned at only lock slide 4 and the locking cover 5 that lock on seat 3, only lock slide 4 comprises annular body and the outward extending boss 41 of annular body arranged on left and right sides, the forward and backward lateral surface of annular body is respectively arranged with " m " type gear groove, the medial surface of annular body is provided with lock pin 44, locking seat 3 offers for the protruding opening that passes and with gear groove suitable convex stupefied 31.Child's tricycle steering lock mechanism structure of the present utility model is simple, firmly stable and can free locking and unlock front-wheel steering as required, uses flexibly and convenient.
The erection procedure of child's tricycle steering lock mechanism of the present utility model is as follows:
One, only lock slide 4 be contained on locking seat 3 with in the groove of only lock slide 4 mating shapes, and " m " type gear groove and convex stupefied 31 matches, only the boss 41 of lock slide 4 be placed on the opening part locking seat 3, then locking cover 5 is covered, finally use countersunk head screw 6x2 to be connected firmly by whole lockout mechanism;
Two, lock the base 32 that to be provided with bottom seat 3 and to connect head tube 1 and base 32 be provided with hook, head tube 1 offering the perforate suitable with hook, is contained in the upper surface of head tube 1 by lockout mechanism, note hook in direction, press until hook hooks head tube 1;
Three, then following bowl 13 is inserted the lower surface of head tube 1;
Four, the standpipe of front fork 2 passed the centre hole of following bowl 13 and be upwards inserted on the lockout mechanism of head tube 1 upper surface, standpipe offers for lock pin insert perforate and this perforate is corresponding with lock pin, then be enclosed within the standpipe of front fork 2 by handlebar 7 supervisor, handlebar 7 offers the fluting passed for lock pin on being responsible for;
Five, nut 11 is placed in the hole of headstock bonnet 9, headstock protecgulum 8 and headstock bonnet 9 are enclosed within handlebar 7 respectively, lock with self-tapping screw 12x6, finally with bolt 10, headstock front and rear covers, handlebar 7, front fork 2 are worn together and lock.
Child's tricycle steering lock mechanism of the present utility model principle of work as follows:
Respectively there are 2 " m " type gear grooves the two sides, front and back of only lock slide 4 of the present utility model, " m " type gear groove is made up of the first detent 42 and the second latch recess 43, thus forming two gears, these two gears all can match to realize unlocking and locking with the column type convex stupefied 31 of locking seat 3;
Lock pin of the present utility model is column type lock pin and is positioned at the right part of only lock slide 4, when pressing the right boss of only lock slide 4, column type convex stupefied 31 and the second latch recess 43 fasten, and only the round pin position of lock slide 4 is in the perforate of front fork 2, whole front component is in the lock state, and namely handlebar 7 is responsible for and relative motion can not be occurred with front fork 2 standpipe, and such front-wheel can only seesaw, can not turn to, be convenient to the head of a family under this state and carry out; When pressing the configured left boss of only lock slide 4, column type convex stupefied 31 and the first latch recess 42 fasten, and only the round pin of lock slide 4 departs from the perforate of front fork 2, makes whole front component be in released state, front-wheel can seesaw and left and right turn, and this state is used for children and rides.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
