The specific embodiment
Below in conjunction with specific embodiment, the utility model is specifically described.
Embodiment: as shown in Figures 1 to 9, children's vehicle frame of Quick folding, comprises forward foot in a step group 8, rear foot group 10, handgrip group 9, two foldable structures; Each foldable structure comprises hypozygal 1, upper joint 2, joint support seat 3; In each foldable structure, hypozygal 1 is connected with forward foot in a step group 8; Upper joint 2 is connected with handgrip group 9; Joint support seat 3 is connected with rear foot group 10; Hypozygal 1 is rotatably connected with joint support seat 3, and upper joint 2 is rotatably connected with joint support seat 3; Interlock connecting rod 4 its one end and the upper joint 2 that can make hypozygal 1, upper joint 2 produce each other the rotation of opposite sense interlock are rotatably connected, and described interlock connecting rod 4 its other ends and hypozygal 1 are rotatably connected; Also comprise and can limit the control mechanism that hypozygal 1, upper joint 2 rotate relative to joint support seat 3.Realize interlock with interlock connecting rod 4, compared with prior art simple in structure.
Upper joint is being provided with the first teat 101 with the joint support seat end that is rotatably connected; Described hypozygal is being provided with the second teat 102 with the joint support seat end that is rotatably connected; The face vertical with the second pivot center is A face, when forward foot in a step group 8, rear foot group 10, handgrip group 9 are deployed into normal position, control mechanism puts between the first teat 101, the second teat 102 and contacts with the first teat, the second teat, the projection that the first teat, the second teat produce on A face 103 has space each other, and control mechanism is arranged in this space.
Can certainly adopt such improvement structure, upper joint and hypozygal are not just limited to teat, can be draw-in groove or hole yet, need only all passable that control mechanism can insert.Being upper joint is being provided with the joint support seat end that is rotatably connected the draw-in groove or the hole that allow control mechanism insert.Hypozygal with joint support seat be rotatably connected end be provided with allow control mechanism insert draw-in groove or hole.These structures are all the rotations of to control or limiting upper joint or hypozygal in order to realize.
Control mechanism consists of the piece 5 that returns the vehicle to the garage and knock off, spring 6, stay cord 7, and stay cord 7 is connected with the piece 5 that returns the vehicle to the garage and knock off, and spring 6 provides the reset force piece 5 that makes to return the vehicle to the garage and knock off to reach gap.
During application, whole fold mechanism is provided with shell outward.Appearance looks elegant, safety.
Principle of work: as shown in Fig. 4, Fig. 5, Fig. 6, when needs return the vehicle to the garage and knock off, pull the stay cord 7(steel cable that returns the vehicle to the garage and knock off), the piece 5 that returns the vehicle to the garage and knock off moves downward and leaves upper joint 2 and hypozygal 1, handgrip group 9 under Action of Gravity Field to the 10 directions motions of rear foot group, the group of the forward foot in a step simultaneously 8 under the connecting rod 4 that returns the vehicle to the garage and knock off drives to the action of returning the vehicle to the garage and knock off that has been synchronized with the movement of rear foot group 10 directions.
In like manner, when car will be launched, both hands are held two handgrips and are upwards carried, now interlock link work also drives the synchronous upward movement of forward foot in a step group, when forward foot in a step group and handgrip group move to parallel position, a piece that returns the vehicle to the garage and knock off resets and blocks upper joint and hypozygal completes the action of exhibition car under the promotion of the spring that returns the vehicle to the garage and knock off.Forward foot in a step group or handgrip group are upwards launched, and due to the existence of connecting rod, they produce interlink function.Forward foot in a step group or handgrip group are launched in rational position simultaneously, and a piece that then returns the vehicle to the garage and knock off enters between the first teat, the second teat, upper joint, and hypozygal rotates difference, has realized the fixing of expanded position.
The above is only the specific embodiment of the present utility model.But the fixed protection domain of the utility model is not limited to this.Any be familiar with those skilled in the art the utility model disclose after; the variation that can expect easily or alternative; within all should being encompassed in protection domain of the present utility model, therefore protection domain of the present utility model should be as the criterion according to the requirement of claims.
