The specific embodiment

Below in conjunction with accompanying drawing the utility model is elaborated.

As shown in Figure 1, 2, the singlehanded Collaping device of children trolley comprises vehicle frame, wheels, handle pipe 4, control setup 10 and folding mechanism 9.The top of handle pipe 4 is handle transverse tube 41, and the lower end of handle pipe 4 links to each other by folding mechanism 9 with vehicle frame, and folding mechanism 9 links to each other with the straight pin 2 of control setup 10 by the trailing cable 3 in the pipe.Control setup 10 is fixedly connected on the middle part of handle transverse tube 41.

Control setup 10 comprises upper shell 1, lower house 2, button 6, and upper shell 1 is interlocked with lower house 6 and forms a housing, and this enclosure interior forms accommodation space, and its two ends are fixedly connected on the handle transverse tube 41 of both sides.This lower housing portion forms downward opening V-arrangement spigot surface 501, lower housing portion stretches into button 6, and button 6 can slide up and down along housing, and the end 61 that presses of button 6 is knob-shaped, the top of button 6 forms opening V-arrangement up and pushes away the face of pulling 601, and V-arrangement pushes away the upper end 13 curved shapes that collude of the face of pulling 601.

V-arrangement pushes away the corresponding setting up and down mutually of the face of pulling 601 and V-arrangement spigot surface 501, and two straight pins 2 push away V-arrangement spigot surface 501 common supports in face of pulling 601 and the housing wall by the V-arrangement of button.Produce under the effect of pulling force at 9 pairs of trailing cables of folding mechanism 3, straight pin 2 is on two V-arrangement faces all the time.

The upper end of button 6 outwards forms projection 11, and children trolley is in the normal state down, and this projection is pushed up mutually with housing, breaks away from housing toward gliding to prevent button 6.

Stretch into safety locking pin 7 one sideslip dynamic formula of button 6, top spring 8 in the safety locking pin 7, the other end of spring 8 pushes up mutually with button 6 internal protrusion things 12.Children trolley is under the normal condition, and the elastic force of spring 8 is exposed to outside the button 6 compression part 701 and the stop part 702 on the safety locking pin 7, and wherein, stop part 702 pushes up mutually with housing, thus prevent random pressing keys 6 and the mistake return the vehicle to the garage and knock off.

Children trolley is under the normal condition, as shown in Figure 3, the V-arrangement that the tension of trailing cable 3 makes straight pin 2 withstand button 6 pushes away the face of pulling 601, safety locking pin 7 is under the elastic force effect of spring 8, compression part 701 and stop part 702 are exposed to outside the button 6, stop part 702 pushes up mutually with housing, and button 6 can't up slide.When returning the vehicle to the garage and knock off, push safety locking pin 7, safety locking pin 7 inwardly slides and compression springs 8, breaks away from fully and the contacting of housing until stop part 702, and at this moment, button 6 loses and stops and can up slide.Pressing keys 6 upwards, straight pin 2 pushes away at V-arrangement under the pressure effect of the face of pulling 601, along V-arrangement spigot surface 501 upward movements, as shown in Figure 4, straight pin 2 drives trailing cable 3 simultaneously and does the tractive motion, makes folding mechanism 9 work, folding mechanism 9 unlocks, and reaches the purpose of returning the vehicle to the garage and knock off.Then, under the restoring force effect of folding mechanism 9, trailing cable 3 drives straight pin 2 and replys in original position, and straight pin 2 compacting V-arrangements push away the face of pulling 601, make button 6 return back to original position downwards, and subsequently, safety locking pin 7 also resets under the effect of spring 8.
