The specific embodiment
below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further elaborated.
backrest regulating mechanism referring to the children trolley shown in Fig. 1～5, comprise the backrest that the vehicle frame with children trolley is rotatably connected, this backrest comprise be positioned at the back support bar 1 of both sides with for being connected the cross assembly 4 of both sides back support bar 1, this cross assembly 4 comprises two struts 41 and two connecting rods 42 that intersect, two strut 41 places of intersecting are rotationally connected by bearing pin 43, one end of strut 41 is hinged in the back support bar 1 of a side, its other end is hinged on the other end of connecting rod 42 of opposite side, by cross assembly 4 backrests, can realize horizontal folding, after backrest folding as shown in Figure 5.
shown in Fig. 1, Fig. 2, in the back support bar 1 of both sides, be equipped with for back support bar 1 being locked to the locked component 2 on vehicle frame, locked component 2 comprises along the pole length direction of back support bar 1 to be located at slidably dead bolt 21 in back support bar 1 bar chamber, to be set in slidably the sliding sleeve 22 of back support bar 1 outside, dead bolt 21 is fixing by sliding pin 23 with sliding sleeve 22, in back support bar 1, offer the chute (not shown) of extending along back support bar 1 length direction, sliding pin 23 is located in above-mentioned chute slidably.In the bar chamber of back support bar 1, be also provided with one for the spring 24 of locked component 2 along its direction of slip elastic-restoring force is provided, in the bar chamber of back support bar 1, be provided with a locating part 25, turning cylinder when this filamentary member 25 that is strut 41 are hinged with back support bar 1, conflicts respectively on locating part 25 and dead bolt 21 in the two ends of spring 24.Under the resilient force of spring 24, dead bolt 21 is outwards ejected its bottom and is stretched out outside the bar chamber of back support bar 1 and stably kept the lock-out state with vehicle frame.
shown in Fig. 1～4, this backrest regulating mechanism also comprises for the unlock component 3 to locked component 2 releases, this unlock component 3 comprises catch base 31, by rotating shaft 33, is connected to rotationally the handle 32 on catch base 31, handle 32 33 upsets along the vertical direction around the shaft.Between handle 32 and the sliding sleeve 22 of both sides, be also connected with trailing cable 34, by pulling trailing cable 34 can drive sliding sleeve 22 along sliding in back support bar 1, the sliding elastic force upward sliding that drives dead bolt 21 to overcome spring 24 on sliding sleeve 22, finally makes the locking of dead bolt 21 disengagings and vehicle frame.Here, catch base 31 is arranged on regularly two struts 41 and intersects on the bearing pin 43 connecting, the lower end of the trailing cable 34 of both sides is separately fixed on the sliding sleeve 22 of both sides, and its upper end fixes and forms with one trailing cable and be connected to the same position place of handle 32, as a point place in Fig. 4.Setting can make operator shake hands in operation at 32 o'clock like this, and the pulling force that the sliding sleeve 22 of both sides is subject to is consistent, thereby makes the dead bolt 21 of both sides realize synchronizing unlocking.Handle 32 is roughly L-type, and trailing cable 34 is fixed therein in a limit portion, and another side portion can be used for the operation handle operating portion of 32 o'clock, 32 the both sides portion of simultaneously shaking hands form to shake hands 32 spin upside down spacing.
below specifically set forth the specific works process of the present embodiment:
shown in each accompanying drawing, under normal conditions, backrest is in deployed condition, under the resilient force of spring 24, dead bolt 21 goes out along the length direction of back support bar 1 is pushed outwards, and the bottom of dead bolt 21 has at least part to expose in the outside of back support bar 1 to make backrest and vehicle frame keep stable lock-out state.When needs regulate backrest, operator only need to pull the handle 32 32 upwards upsets that make to shake hands, handle 32 upsets pull trailing cable 34 and drive sliding sleeve 22 along sliding on the length direction of back support bar 1, the elastic force that dead bolt 21 overcomes spring 24 is simultaneously upper is slidingly separated and release the bottom of dead bolt 21 and vehicle frame, the just angle of adjustable backrest after release.After backrest is adjusted, unclamp handle 32, under the resilient force of spring 24, dead bolt 21, sliding sleeve 22 glide along the length direction of back support bar 1, until dead bolt 21 locks again with vehicle frame.This backrest regulating mechanism is simple in structure, takes up room little, by one-handed performance, can realize the adjusting to children trolley backrest, regulates more convenient.
above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
