Token name is claimed among the figure:
1: hand push frame, 2: underframe, 3: connect catch, 31: axis hole, 32: chute, 33: blind end; 34: opening, 35: locating hole, 4: pivot, 41: nut, 5: locking device; 51: locking knob, 52: nut, 10: vehicle frame, 11: left side skeleton, 12: the right side skeleton; 13: support closing-folding mechanism, 14: front-wheel, 15: trailing wheel, 20: deployed condition, 30: folding state.
The specific embodiment
Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, this utility model comprises underframe 1 and hand push frame 2, and wherein hand push frame 2 persons of being to use are with the skeleton that handle is installed of trolley, and underframe is the skeleton that is used to install support wheel.Underframe 1 is provided with one and connects catch 3, hand push frame 2 with is connected catch 3 and is articulated through a pivot 4, this connect catch 3 can with hand push frame 2 backstops in the position of underframe approximate vertical, and can pass through a locking device 5 and lock.Because the handbarrow of prior art is under user mode; Position between hand push frame and the underframe is generally the position of vertical or approximate vertical; Therefore; This utility model when user mode, promptly locking device 5 when locking state, connect catch 3 can with hand push frame backstop in the position of underframe approximate vertical.The position of approximate vertical is meant that hand push frame 2 and underframe 1 can be vertical, also can be near the values 90 degree, and only otherwise influence the go-cart effect, and 90 degree have the angle (between spending to 105 at 75 degree) of less difference all should belong to the protection domain of this utility model.When unscrewing locking device 5, can hand push frame 2 be folded in the position with underframe 1 almost parallel again.The position of almost parallel is meant that hand push frame 2 and underframe 1 can be parallel, also can be that a small angle is arranged, and only otherwise influence the effect of folding, certain included angle (as spending to 10 greater than 0 degree) all should belong to the protection domain of this utility model.Wherein locking device can be the current techique in present technique field, preferred locking knob of this utility model and screw.As preferred version, said connection catch is a U-shaped sheet, this U-shaped sheet and underframe approximate vertical; Its opening 34 is towards identical with the length over end sills direction; Hand push frame 2 inserts in the U-shaped sheet, and a pivot 4 passes hand push frame 2 and makes the hand push frame and be connected the catch pivot joint with the U-shaped sheet and with a nut 41 cooperations, and said U-shaped sheet one side has chute 32; One end of chute 32 forms blind end 33 in the U-shaped sheet; The edge that the other end extends to the U-shaped sheet forms an opening 34, and locking knob 51 passes chute 3 and cooperates with nut 52 with hand push frame 2, hand push frame 2 is locked on the U-shaped sheet or from the U-shaped sheet discharge.
To connect catch and design simplyr in order to make, and size is less, the Position Design that makes chute is more scientific and reasonable in the top position that is positioned at pivot.
In order to make the locking device locking effect better, and when locking, be not subjected to displacement, one locating hole 35 arranged at the blind end of chute.The diameter of this locating hole is bigger slightly than the width of chute, after locking knob falls into locating hole, just can not be subjected to displacement.
In order to make locking effect connect the backstop better effects if of catch in succession, said connection catch is processed by metal material.
During use, unclamp locking knob 51, hand push frame 2 is opened, after locking knob 51 falls into locating hole 35, locking locking knob 51.During folding, unclamp locking knob 51, hand push frame 2 is pulled down, locking knob 51 slides into the opening 34 at chute edge along chute 3, even can skid off opening 34, is folded on the underframe 1 until hand push frame 2, with underframe 1 almost parallel.
See Fig. 1, Fig. 5 and Fig. 6; It is the following gliding style folding pushchair that contains above-mentioned folding structure; This handbarrow comprises vehicle frame; This vehicle frame 10 has a deployed condition 20 and a folding state 30, and said vehicle frame 10 comprises a left side skeleton 11, a right side skeleton 12 and the support closing-folding mechanism 13 that the folding of left and right side skeleton is closed up; This left and right side skeleton comprises hand push frame 2 and underframe 1, and the front-end and back-end of underframe 1 are separately installed with front-wheel 14 and trailing wheel 15.
Under the principle and principle of this utility model, the protection domain that understandable any various replacements with same function or effect that the foregoing description is made of the technical staff in present technique field or modification all belong to this utility model.
