Abstract

The utility model discloses a baby carriage joint mechanism which is equipped with a single holder, wherein an end thereof is pin joint on the hand pipe and another end extends a pulling position for moving by hand. The holder is equipped with a positioning portion buttoning engaged with the button portion of the front pipe, which keeps buttoning engagement with the end of the front pipe or the lower joint by the elastic component and keeps the baby carriage skeleton to extend for tightening condition. When the skeleton is to be folded, the operator pulls the pulling position to make the buckles place rotate in contrast with the hand pipe axis for releasing and separating the front pipe end or the lower joint, and to make the skeleton in the releasing and foldable state, thereby the safe buttoning result can be achieved with the simple component.

Description

Baby carriage joint structure

Technical field

The utility model relates to a kind of baby carriage joint structure, the main single Button Block that is articulated in handle pipe that utilizes, and the manner of execution that rotates with respect to the handle pipe axis by this Button Block reaches the effect of fastening safely.

Technical background

Perambulator is mainly used in the carrying baby, deposit for when transporting and place, being able to smaller volume, therefore its skeleton is folded into one usually and is folded state, for the expansion of control skeleton is fixed and is folded, the perambulator skeleton usually uses a folding structure to be controlled, therefore multi-form folding structure in response to and give birth to.Traditional folding structure, as shown in Figure 1, including one is installed on the upper joint 2 on the handle pipe 1 and is fixed in front foot pipe 3 ends and end face has the hypozygal 4 of a positioning groove 41, wherein handle pipe 1 is to be articulated in hypozygal 4, and handle pipe 1 is provided with a pull bar 11 can drive mobile radius stay 12, radius stay 12 mainly remains in the positioning groove 41 by elastic parts 10 and with it and forms the clip stationary state, when desiring to fold skeleton, then utilize pull bar 11 pulling radius stays 12 and break away from positioning groove 41 and form the state that folds that discharges.Above-mentioned traditional folding structure only utilizes radius stay to cooperate positioning groove to be fixed, and intensity is comparatively not enough, and the plastic breakage because of hypozygal causes the unexpected folding of skeleton easily.

The structure that No. the 5605409th, US Patent then is to move and engaging front foot pipe end on the main axis by upper joint in handle pipe, though its intensity is strengthened, but it discharges and the snap action mode is a straight-line motion, it is complete that its handle pipe and front foot pipe must just can engage under parallel situation, so this structure causes the incomplete situation of engaging to take place easily.

Summary of the invention

Main purpose of the present utility model is at structure in the past comparatively complexity and the not good shortcoming of intensity in the assembling of spare part, a kind of folding is provided, launches smooth and easyly, and the baby carriage joint structure of preferable intensity is arranged.

Main technical schemes of the present utility model is: this baby carriage joint structure is connected between the handle pipe and front foot pipe on the perambulator skeleton in the mode of bending relatively, both can make the two overlap continuity mutually, can discharge again, this articulation structure comprises the hypozygal that is fixed on the front foot pipe, has the pivot points that can articulate with handle pipe and an end that buckling parts be arranged; One end is articulated on the handle pipe, the other end extends the Button Block that affects the position that can move for hand, has the location division handle pipe of this perambulator and pin pipe can be overlapped mutually by affecting the position to be socketed in the buckling parts of hypozygal with rotation mode on the Button Block; Be installed on the maintenance Button Block between skeleton and the Button Block and the elastic parts of buckling parts socket.

The utility model and utilize single Button Block, the one end is articulated on the handle pipe, the other end extends one can affect the position for what hand was moved, location division with front foot pipe end or hypozygal buckling parts clip is arranged on this Button Block, and this Button Block mainly keeps fastening the location with front foot pipe end or hypozygal by an elastic parts, it is formed launch stationary state, and when desiring the folding skeleton, promotion affects the position and makes Button Block break away from buckling parts in rotary manner, skeleton is formed discharge collapsible state, reached the effect that safety fastens so as to reaching with easy member.And folding, expansion are smooth and easy, and preferable intensity is arranged.

The specific embodiment

As Fig. 2, Fig. 3, shown in Figure 4, baby carriage joint structure of the present utility model, main system is installed on the perambulator skeleton 5, so as to the expansion and the folding of control perambulator skeleton 5.Perambulator skeleton 5 includes front foot pipe 51 connected to one another, rear foot tube 52, seat pipe 53, handle pipe 54 and articulation structure 6.Wherein pin-jointing piece 55 is extended in the appropriate location, lower end of handle pipe 54, so as to articulating articulation structure 6, a long slot bore 541 is set on the handle pipe 54, so as to moving of restriction articulation structure 6.Perambulator skeleton 5 is to form by these articulation structure 6 control perambulator skeletons 5 to launch stationary state and discharge folding state.

Shown in Fig. 5, Fig. 6 A, Fig. 6 B, baby carriage joint structure of the present utility model, articulation structure 6 include Button Block 61, hypozygal 62 and an elastic parts 63.Hypozygal 62 is fixedly connected on the upper end of front foot pipe 51, on a buckling parts 9 is arranged.Buckling parts 9 is extended by the end of front foot pipe 51, also can directly be extended or is one-body moldedly gone out a projection by hypozygal 62, sees Fig. 8.The pivot points 621 that can articulate handle pipe 54 ends is arranged on the hypozygal 62.Button Block 61 is articulated on the pin-jointing piece 55 of handle pipe 54, has the position of affecting 611 to being less than a side, make the operator can utilize this to affect position 611 to drive of the axis rotation of these Button Blocks 61, and make in the scope of Button Block 61 long slot bore 541 on handle pipe 54 and move, see Fig. 6 A with respect to handle pipe 54.In the present embodiment, affect position 611 to be positioned at anterior position, promote for the operator.In addition, affect position 611 also can be arranged at the both sides of Button Block 61.Affect position 611 can be a tongue or groove all can, so as to for operator's pulling; Button Block 61 has a location division 612 with respect to buckling parts 9.In the present embodiment, location division 612 is a groove.Buckling parts 9 is inserted in or be left in this location division 612 can with Button Block 61 rotations, and utilize elastic parts 63 under normality, to keep buckling state, produce overlap joint and launch fixing and discharge perambulator skeleton 5 so as to handle pipe 54 and the front foot pipe 51 that reaches perambulator skeleton 5 and make handle pipe 54 reach the purpose of folding with front foot pipe 51 bendings.For making the utility model be able to singlehanded operate the Button Block of skeleton both sides simultaneously, can utilize a single handed release mechanism and drive the Button Block of both sides simultaneously, to reach the effect of single handed release by moving part.

As shown in Figure 7, baby carriage joint structure of the present utility model, buckling parts 9 is a projection.Can install reinforcing chip 66 in the location division 612 additional to strengthen the intensity of Button Block 61.

As shown in Figure 9, the baby carriage joint structure of another embodiment of the utility model, Button Block 61 is finished the action that perambulator skeleton 5 launches to fasten or discharge folding with respect to handle pipe 54 axis 7 rotation modes, therefore the buckling parts 9 of hypozygal 62 can be a groove, and the location division 612 of Button Block 61 interchangeable be a projection.Can obtain identical effect equally.

Comprehensive above embodiment as can be known, maximum characteristics of the present utility model are that Button Block is fastening with respect to handle pipe axis rotation mode or to discharge, thereby reach the effect of safety fastening with easy member.
