The specific embodiment
Below in conjunction with accompanying drawing the present invention is elaborated.
Shown in Fig. 1-6, handle pipe 1 roughly is the U type, and its top is handle portion, and the middle part of handle is provided with folding control device 101, and folding control device 101 can adopt prior art.The seat of honour, joint 1701 of the lower end of handle pipe 1 and folding mechanism 17 is fixedly linked, and the seat of honour, joint 1701 articulates with following 1702 in the joint of folding mechanism 17.
The concrete structure of folding mechanism 17 is referring to Fig. 4.Handle pipe 1 built-in trailing cable 1709, the upper end of trailing cable 1709 links to each other with the control setup 101 that returns the vehicle to the garage and knock off, and is upwards spurred trailing cable 1709 and is removed locking to folding mechanism 17 by the control setup 101 that returns the vehicle to the garage and knock off.
The lower end tube wall of handle pipe 1 is offered corresponding a pair of oblique elongated slot 1703, and the seat of honour, joint 1701 is installed in the lower end external stability of handle pipe 1.
The upper end external stability of handle pipe 8 is installed the joint following 1702, and the top that the joint is following 1702 and the bottom at the seat of honour, joint 1701 articulate.Following 1702 in joint forms spigot surface 302, has engagement groove 301 on the spigot surface 302; The sliding lock pin 1707 of joining on the spigot surface 302, lock pin 1707 can along spigot surface 302 slide and stopper in engagement groove 301.
The inside, lower end of handle pipe 1 sets firmly a drive seat 1705, and drive seat 1705 forms the oblique elongated slot 1703 corresponding through holes with handle pipe 1, and this through hole can be for lock pin movement.Form a spatial accommodation in the drive seat 1705, insert L type drive block 1706 in the spatial accommodation, the turning point of L type drive block 1706 is rotatedly connected by rotating shaft and drive seat 1705.The end, one side of L type drive block 1706 and the lower end of trailing cable 1709 are affixed, offer the hole 602 that an elongated slot 601 reaches on the another side of L type drive block 1706, and hole 602 is communicated with an end of elongated slot 601.L type drive block 1,706 one ends connect an end of extension spring 1708, and the other end of extension spring 1708 is hung on the drive seat 1705.
The middle part of lock pin 1707 forms an annular groove 701, and lock pin 1707 can pass hole 602, is convenient to assembling.After lock pin 1707 passes hole 602, annular groove 701 is fastened in the elongated slot 601 of L type drive block 1706, the both ends of lock pin 1707 place the oblique elongated slot 1703 of handle pipe 1 bottom, and lock pin 1707 can slide along elongated slot 601 and oblique elongated slot 1703.
Folding mechanism is in the lock state, and at this moment, under the effect of extension spring 1708, lock pin 1707 is inserted in the engagement groove 301, and 1702 at the seat of honour, joint 1701 and the seat of honour, joint can't be rotated.
When unlocking, operate the control setup 101 that returns the vehicle to the garage and knock off, upwards spur trailing cable 1709, drive seat 1705 is rotated along axle, the rotation of drive seat 1705 makes the lock pin 1707 of clamping in the elongated slot 601 shift out engagement groove 301, and at this moment, following 1702 in the seat of honour, joint 1701 and joint can be rotated, fold in the folding process, the spigot surface 302 that lock pin 1707 is following 1702 along the joint slides until disengaging.Then, lock pin 1707 returns back to elongated slot 601 bottom under the effect of extension spring 1708.
During 17 operations of locking folding mechanism, backward rotation handle pipe 1 and handle pipe 8, when going to certain, the spigot surface 302 that lock pin 1707 sliding upper joints are following 1702, and be rotated further, insert in the engagement groove 301 until lock pin 1707, the seat of honour, joint 1701 and following 1702 in joint can not be rotated, thereby locked folding mechanism 17.
The lower end of handle pipe 8 is articulated in the front portion of frame-type underframe 10, and the front upper of underframe 10 is installation foot pedal 102 also, wheels 9 and back wheels 11 before install the below of underframe 10.
Handle pipe 1 also is connected a mounting pipe 4 with 8 of handle pipes, and mounting pipe 4 roughly is the U type, and the upper end of mounting pipe 4 and handle pipe 9 are hinged, the lower end of mounting pipe 4 is articulated on the sliding sleeve 6, be coated at the outer wall of handle pipe 8, sliding sleeve 6 endoporus are tapered, are inner cone sliding sleeve 6 sliding types; Lining 801 outer cylinders are tapered, are outer cone, and this outer cone matches with the inner cone of sliding sleeve 6.
The upper end of also hinged arc strut bar 7 on the sliding sleeve 6, the lower end of strut bar 7 is articulated in the rear portion of underframe 10.
Attaching parts 5 is the U type, and it is coated at strut bar 7, Yi Bian be fixed on the mounting pipe 4, an end of another side and connecting rod 15 is hinged, and an end of the other end of connecting rod 15 and mounting connecting rod 14 is hinged, and the other end of mounting connecting rod 14 and strut bar 7 are hinged.
The both sides of service plate 3 respectively fixedly install a service plate connecting rod 31, the other end of service plate connecting rod 31 is articulated in the approximate mid-section position of mounting pipe 4, the stage casing of service plate connecting rod 31 also is connected on the handle pipe 1 by brace 2, and brace 2 is hinged with the connection mode of service plate connecting rod 31, handle pipe 1.
Backing tube 1 is the U type, and the termination of backing tube 16 and connecting rod 15 are hinged.The below an upper section of backing tube 16 is provided with regulating control 18, and two belts 1801 of the front end of regulating control 18 pass backing tube 16 backs and are fixedly linked with handle pipe 1.Regulating control 18 tops are provided with a draw ring 1802, and the bottom of regulating control 18 is provided with button 1803, upwards spur draw ring 1802, and belt 1801 is pulled out from regulating control 18 can be to adjusted backing tube 16; Compress into button 1803, and press down backing tube 16 and can turn down backing tube 16, make it take advantage of personnel's sitting posture in adapting to, the adjusting of backing tube 16 only needs one-handed performance to finish.
The children trolley open mode when returning the vehicle to the garage and knock off, is pushed folding control device 101 as shown in Figure 2, and folding control device 101 pulling trailing cables make the locking of its releasing to folding mechanism 17, thereby following 1702 in the seat of honour, joint 1701 and joint can relatively rotate just.At this moment, the handle pipe 1 of overturning forward, because the normal-running fit of each point of connection relation, each parts just can correspondingly rotate and draw close to underframe 10, referring to Fig. 5, in folding process, sliding sleeve 6 along handle pipe 8 to lower slider, the lower end that makes the upper end of strut bar 7 and mounting pipe 4 is also to lower slider, and draws close to underframe 10; And basket connecting rod 13 also rotates forward, pulling basket pipe 12 is to reach, contracted forward until folding when putting in place in the rear end of basket pipe 12, after the retraction within the wheels 11, thereby the car load width of folding back children trolley is the width between front and back wheel, referring to Fig. 6, after children trolley is folding, backing tube, basket pipe and service plate all close in the car body, thereby have dwindled the volume of folding back children trolley, are convenient to collection, transportation and mobile like this.
