Embodiment

The utility model is described in further details with reference to embodiment：

A kind of folding frame of handcart, as shown in Figs. 1-3, it includes car body to structure, and the car body is equipped with the first folding Stack structure, the second foldable structure, the 3rd foldable structure, the 4th foldable structure and the 5th foldable structure.

The up and down connection of first foldable structure and the second foldable structure, first foldable structure include hand handle group Part 1, return the vehicle to the garage and knock off box 2 and the hand handle telescoping tube 3 that is connected with 1 both ends of handle assembly for being arranged on the middle part of handle assembly 1, second folding Stack structure includes hand handle casing 4, and the hand handle telescoping tube 3 is located in hand handle casing 4 and living up and down along the inner wall of hand handle casing 4 It is dynamic, complete folding for vehicle body upper portion point.

Second foldable structure is connected with the 3rd foldable structure by the first bending joint 5, first bending joint 5 Including bending hypozygal 18 and bending upper joint 19, the bending hypozygal 18 be combined with bending upper joint 19 surround it is hollow Enclosure space, spring 23, bending gear 22, rotation gear 21 and sliding block 20 are equipped with the enclosure space, in the bending The recessed edge coordinated with the convex edge on bending gear 22 is equipped with joint 19 and bending hypozygal 18, passes through matching somebody with somebody for convex edge and recessed edge Close, 22 holding of bending gear is between bending upper joint 19 and bending hypozygal 18, the bending gear 22 and rotation gear 21 Center open up coaxial hole, the axis coordinated with the hole is arranged on the middle part of bending hypozygal 18, and the spring 23 is set Between bending hypozygal 18 and bending gear 22, the sliding block 20 and rotation gear 21 are arranged in bending upper joint 19.This Sample, by inner wall slamming down of the hand handle telescoping tube 3 along hand handle casing 4, makes to be arranged on cunning, it is necessary to when folding baby trolley 20 inward turning rotating disk 21 of block rotates, and when rotation gear 21 rotates, 22 holding of bending gear is closed on bending hypozygal 18 and bending It cannot be rotated in section 19.Under the action of sufficiently large impact, rotation gear 21 is rotated to be departed from bending gear 22, promotes bending Gear 22 compresses the spring 23 of inner side, and bending gear 22 departs from bending upper joint 19, and 18 band of instantaneous time bending hypozygal is started Down tube 6 is folded up, drives the 3rd foldable structure being connected with hand handle down tube 6 and the 4th foldable structure to be folded up, at the same time Hand handle casing 4 is folded down, and is easily collapsed vehicle and is folded, smoothly complete the unlock of the first bending joint 5, realizes Return the vehicle to the garage and knock off folding, to facilitate storage and transport.

The 3rd foldable structure hand handle down tube 6, the 4th foldable structure 15 and the 5th foldable structure of front foot connecting rod after two Bank 9 is connected by the second bending joint 8, is equipped with shaft in second bending joint 8, is connected by shaft, the described 3rd Foldable structure includes hand handle down tube 6, the mounting component 14 being connected with hand handle down tube 6, armrest assembly 13 and rear connecting leg 7, the hand Down tube 6, rear connecting leg 7 are connected by the first bending joint 5 with hand handle casing 4.When the first bending joint 5 completes the same of unlock When, hand handle down tube 6 drives the second bending joint 8 to act, and then drives the 3rd foldable structure, the 4th foldable structure to realize and fold receipts Car.4th foldable structure includes sequentially connected front foot connecting rod 15, front foot component 16 and front truckle 17, and the described 3rd folds The hand handle down tube 6 of structure is connected by the second bending joint 8 with the front foot connecting rod 15 of the 4th foldable structure.This step is returned the vehicle to the garage and knock off completion After, obtain shape as shown in Figure 4.At this moment rear truckle 12 supports ground, can promote walking on the ground.

5th foldable structure includes rear foot lever 9 and rear truckle 12, and the rear truckle 12 passes through the 3rd bending joint 11 It is connected with rear foot lever 9, the rear foot lever 9 of the 5th foldable structure passes through the second bending joint 8 and the 3rd foldable structure, four fold Stack structure connects.Foot lever 9 is equipped with Bending Slide Block 10 afterwards, and the Bending Slide Block 10 is connected with the 3rd bending joint 11.If need When wanting folding volume smaller, Bending Slide Block 10 can be promoted to complete the unlock of the 3rd bending joint 11, be folded up rear truckle 12, At this moment shape as shown in Figure 5 is obtained, front truckle 17 supports ground at this time, can also realize the function of freely carrying out on ground, and Volume smaller, convenient storage.

When baby stroller needs to return the vehicle to the garage and knock off folding, the box 2 that will first return the vehicle to the garage and knock off is pressed into, and unlock hand handle telescoping tube 3 makes it in hand Slide downward in casing 4, then hitting the first bending joint 5 makes its unlock, and hand handle down tube 6 drives the 3rd foldable structure the Realization is folded in two bending joints 8 under the action of shaft to return the vehicle to the garage and knock off, rear truckle 12 supports ground at this time, and volume of returning the vehicle to the garage and knock off if desired is more Small, the Bending Slide Block 10 after can promoting on foot lever 9 makes the 3rd bending joint 11 complete unlock, and rear truckle 12 is folded up, at this time Ground is supported by front truckle 17.

Finally it should be noted that：Above-described embodiment is the utility model and the citing done to clearly illustrate, right absolutely not The restriction of embodiment.For those of ordinary skill in the art, other can also be made on the basis of the above description Various forms of changes or variation, can not carry out exhaustion to all embodiments herein, and it is aobvious and easy thus to extend out The change or variation seen are still fallen among the scope of protection of the utility model.
