Embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
Shown in Fig. 1 to 6; A kind of collapsible hand-pushing support of the utility model; Comprise the supporting frame 1 and passive supporting leg that are used to place object; Supporting frame 1 comprises right cross bar 11 and left cross bar 12, and supporting leg comprises right supporting leg 2 and left branch leg 3, and right supporting leg 2 is installed on right cross bar 11 and the left cross bar 12 and with locking device through whirligig 4 respectively with left branch leg 3 and locatees; Right supporting leg 11 bottoms are equipped with handle 5, and left cross bar 12 two ends are equipped with roller 6.
In the present embodiment, whirligig comprises sleeve base 41, and sleeve base 41 is provided with a pair of boss separated by a distance 7; Locking device comprises locking spanner 8 and locating stud 9, and locating stud 9 passes the center hole of two boss 7, and the length of locating stud 9 is greater than the distance between two boss 7; Be welded with fixed plate 10 on the supporting frame 1 at right cross bar 11 and left cross bar 12 two ends, be provided with preformed hole 20 with locating stud 9 corresponding positions on the fixed plate 10; Thereby can drive locating stud 9 through rotational lock spanner 8 moves along boss 7 axial directions and locating stud 9 is inserted or breaks away from preformed hole 10.
Specifically, be fixed with catch 13 on the locating stud 9, thereby locking spanner 8 is provided with the projection 14 that can promote 8 motions of catch 13 drive locating studs; Right supporting leg 11 is connected with sleeve base 41 through the fixed base 15 that has cylindrical hole.
A kind of collapsible hand-pushing support of the utility model has multiple practical state in use.
As shown in Figure 1, be the holding state of the utility model.Before this state of description, need introduce the structure of fixed plate 10 earlier.As shown in Figure 2, fixed plate 10 is provided with preformed hole 20 along the circular arc direction for to be similar to fan-shaped structure on fixed plate 10, is respectively first preformed hole 21 and second preformed hole 22 that is positioned at the top that are positioned at the below.Under holding state, locating stud 9 inserts first preformed hole 21 of fixed plate 10, and supporting leg plays firm supporting effect to supporting frame 1.
