Detailed description of the invention
as shown in Figure 1 to 9, according to the children trolley of the present embodiment, it comprises the vehicle frame 1 with deployed condition and folded state, front component 2 and wheel assembly 3, vehicle frame 1 comprises the front-wheel support 10 that leading section is provided with front component 2, bottom is provided with the rear wheel support 11 of wheel assembly 3, push rod 12, this children trolley also comprises for the upper end by front-wheel support 10, the locking bindiny mechanism 4 that the upper end of rear wheel support 11 and the bottom of push rod 12 lock relatively, front-wheel support 10 can be realized fast by the setting of locking bindiny mechanism 4, rear wheel support 11, the interlock of push rod 12 draws in.
concrete locking bindiny mechanism 4 comprise be respectively used to connection three parts and by same pivot 13 rotate connect the first Connection Block 41, second Connection Block 42 and the 3rd Connection Block 43, and for by the first Connection Block 41, the blocking device 44 of the second Connection Block 42 and the relative locking of the 3rd Connection Block 43, 3rd Connection Block 43 is between the first Connection Block 41 and the second Connection Block 42, and the 3rd Connection Block 43 offers the elongated hole 430 passing for pivot and slide, first chute 431 and the second chute 432, wherein, first chute 431, the bearing of trend of the second chute 432 is consistent, and intersect with the bearing of trend of elongated hole 430.
in this example, the first Connection Block 41 is fixedly connected with front-wheel support 10, and the second Connection Block 42 is fixedly connected with push rod 12, and the 3rd Connection Block 43 is fixedly connected with rear wheel support 11.
in this example, the first above-mentioned chute 431, second chute 432 extends on same bearing of trend, and the first chute 431 and the second chute 432 to be connected setting by elongated hole 430.
further, the bearing of trend of the first above-mentioned chute 431, second chute 432 is vertical with the bearing of trend of elongated hole 430.Make the first chute 431, second chute 432, elongated hole 430 forms a criss cross through slot.
when go-cart is in deployed condition, along being 0 ~ 30 ° of angle with horizontal direction, direction extends elongated hole 430; First chute 431 and the second chute 432 extend on same bearing of trend, and along being 0 ~ 30 ° of angle with vertical direction, direction extends, in this example, as shown in Figure 4, when go-cart is in deployed condition, elongated hole 430 extends along close to horizontal direction, and the first chute 431 and the second chute 432 extend along the direction perpendicular to elongated hole 430.
in this example, above-mentioned blocking device 44 comprises for by the locking piece 440 of the first Connection Block 41 with the relative locking of the second Connection Block 42, be arranged on the first card column 441 the first Connection Block 41 coordinating with the first chute 431 and locks, be arranged on the second card column 442 the second Connection Block 42 coordinating with the second chute 432 and locks, when locking piece 440 is in the lock state, first card column 441, second card column 442, pivot 13 respectively with the first chute 431, second chute 432, elongated hole 430 matches and to lock relative with the second Connection Block 42 with the first Connection Block 41 for the 3rd Connection Block 43, when locking piece 440 is in released state, pivot 13, first card column 441, second card column 442 can be slided along elongated hole 430, first chute 431 and the second chute 432 respectively.
further, the axial line of the first card column 441, second card column 442 and pivot 13 parallels setting.
further, above-mentioned locking piece 440, specifically comprise the locked groove 440a be opened on the first Connection Block 41, be arranged on the dead bolt 440b being provided with in the second Connection Block 42 and matching with locked groove 440a, further, blocking device 44 also comprises the unlock piece that can make to depart from dead bolt 440b self-locking grooves 440a, further, unlock piece comprises the hauling rope that is connected on dead bolt 440b and is connected to the sliding sleeve 440c be arranged on push rod 12 that the hauling rope other end can slide, after pulling sliding sleeve 440c, depart from dead bolt 440b self-locking grooves 440a, blocking device 44 unlocks.
in sum, the children trolley folding process of the present embodiment is as follows:
pull sliding sleeve 440c, dead bolt 440b and locked groove 440a is departed from, first Connection Block 41 is relative with the second Connection Block 42 to be unlocked, move the second Connection Block 42(push rod 12 downwards), second Connection Block 42 pivotally 13 is rotated, moved down along the second chute 432 by the second card column 442, and the second card column 442 rotates clockwise promotion second chute 432, thus drive the 3rd Connection Block 43(rear wheel support 11) clockwise direction rotation, simultaneously by the rotation of the 3rd Connection Block 43, first card column 441 is moved up along the first chute 431, thus drive the first Connection Block 41(front-wheel support 10) conter clockwise rotates in vehicle frame, and then realize that the first Connection Block 41 is relative with the interlock of the 3rd Connection Block 43 to be drawn in.
and in the present embodiment, children trolley folding process also has two kinds of extraordinary circumstances:
1), when front-wheel support 10 (the first Connection Block 41) is for stationary state, after locking piece 440 unlocks, move push rod 12(second Connection Block 42 downwards), by the second card column 442 pivotally 13 clickwises, and move down along the second chute 432, pivot 13 is moved to the left along elongated hole 430, thus drives rear wheel support 11(the 3rd Connection Block 43) draw close to front-wheel support 10, thus realize folding;
2), when rear wheel support 11(the 3rd Connection Block 43) for stationary state time, after locking piece 440 unlocks, move push rod 12 downwards, by the second card column 442 pivotally 13 clickwises, and move down along the second chute 432, pivot 13 is moved to the left along elongated hole 430, thus makes frame 10(first Connection Block 41 rotarily driving front-wheel of the first card column 441 pivotally 13 conter clockwises) to rear wheel support 11(the 3rd Connection Block 43) draw close, thus realize folding.
above the utility model is described in detail; its object is to allow the personage being familiar with this art can understand content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to Spirit Essence of the present utility model change or modify, and all should be encompassed in protection domain of the present utility model.
