[utility model content]
The utility model has overcome the deficiency of above-mentioned technology, provide a kind of be applicable on the Foldable baby stroller collapsible or the elongation push tube on folding tripper.
For achieving the above object, the utility model has adopted following technical proposal:
A kind of folding tripper of Foldable baby stroller, the movable internal pipe that includes motionless outer tube and can in motionless outer tube, move up and down, the stay cord that in motionless outer tube, is provided with crooked resilient sleeve and passes in the resilient sleeve, the lower end of described resilient sleeve is connected the lower end of motionless outer tube, and the upper end of described resilient sleeve is connected the lower end of movable internal pipe; Spanner on described stay cord upper end is stretched out the back and is arranged on movable internal pipe from the resilient sleeve upper end is connected, described stay cord lower end is connected with movable latch after stretching out from the resilient sleeve lower end, is provided with movable latch to be resetted and make its lower end stretch out the retracing spring of motionless outer tube in motionless outer tube.
Be provided with locating piece down above motionless outer tube internal activity latch, described resilient sleeve lower end withstands on this time locating piece, and described stay cord lower end is passed the back from this time locating piece and is connected with movable latch, and described retracing spring is arranged on down between locating piece and the movable latch; The movable internal pipe interior lower end be provided with can along with movable internal pipe together lifting on locating piece, described resilient sleeve upper end withstands on this on the locating piece, on the described stay cord on this locating piece pass.
Described spanner includes and is arranged on the movable block in the movable internal pipe and is enclosed within the exterior movable sleeve of movable internal pipe, end, described stay cord upper end is fixed on the movable block, on movable internal pipe, be provided with the bar shaped slide opening, connect by the sliding pin that can in the bar shaped slide opening, slide up and down between this movable block and the movable sleeve.
Described down locating piece by dowel fixes in motionless outer tube, described go up locating piece by dowel fixes in movable internal pipe.
The beneficial effects of the utility model are: 1, the utility model comprises motionless outer tube and the movable internal pipe that can move up and down in motionless outer tube; Crooked resilient sleeve and the stay cord that passes in the resilient sleeve in motionless outer tube, all stay cord all is in the state of tightening when push tube extends or do not extend, like this, stay cord can play the release effect when push tube extends or do not extend, and satisfies people's demand like this;
2, the utility model is simple in structure, easy to operate.
[description of drawings]
Fig. 1 is that the utility model is arranged on the block diagram on the extending hand push frame;
Fig. 2 is an exploded view of the present utility model;
Fig. 3 is a planar view of the present utility model;
Fig. 4 is the A-A section-drawing of Fig. 3.
Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:
[specific embodiment]
Referring to Fig. 1-4, the utility model is a kind of folding tripper of Foldable baby stroller, the movable internal pipe 2 that includes motionless outer tube 1 and can in motionless outer tube 1, move up and down, the stay cord 4 that in motionless outer tube 1, is provided with crooked resilient sleeve 3 and passes in the resilient sleeve 3, the lower end of described resilient sleeve 3 is connected the lower end of motionless outer tube 1, and the upper end of described resilient sleeve 3 is connected the lower end of movable internal pipe 2; Spanner 7 on described stay cord 4 upper ends are stretched out the back and are arranged on movable internal pipe 2 from resilient sleeve 3 upper ends is connected, described stay cord 4 lower ends are connected with movable latch 5 after stretching out from resilient sleeve 3 lower ends, are provided with movable latch 5 to be resetted and make its lower end stretch out the retracing spring 6 of motionless outer tube 1 in motionless outer tube 3.Described spanner 7 can drive stay cord 4 relative resilient cover 3 and move up and make movable latch 5 ends regain in the motionless outer tube 1.
Above motionless outer tube 1 internal activity latch 5, be provided with locating piece 8 down, described resilient sleeve 3 lower ends withstand on this time locating piece 8, described stay cord 4 lower ends are passed the back from this time locating piece 8 and are connected with movable latch 5, and described retracing spring 6 is arranged on down between locating piece 8 and the movable latch 5; Movable internal pipe 2 interior lower end be provided with can along with movable internal pipe 2 together lifting on locating piece 9, described resilient sleeve 3 upper ends withstand on this on locating piece 9, described stay cord 4 upper ends locating piece 9 on this passes.
Described spanner 7 includes the movable block 71 that is arranged in the movable internal pipe 2 and is enclosed within movable internal pipe 2 exterior movable sleeves 72, end, described stay cord 4 upper end is fixed on the movable block 71, on movable internal pipe 2, be provided with bar shaped slide opening 10, connect by the sliding pin that can in bar shaped slide opening 10, slide up and down between this movable block 71 and the movable sleeve 72.
Described down locating piece 8 by dowel fixes in motionless outer tube 1, described go up locating piece 9 by dowel fixes in movable internal pipe 2.
Principle of work of the present utility model is as follows: when the hand push frame is in not elongated condition, be that movable internal pipe 2 is not when motionless relatively outer tube 1 is upwards pulled out, at this moment, want folding release, upwards spur movable sleeve 72 with hand, movable sleeve 72 drives movable block 71 by sliding pin and moves up along bar shaped slide opening 10, move up thereby drive the stay cord of tightening 4, because movable internal pipe 2 is not moving, the last locating piece 9 that is fixed on the movable internal pipe 2 is just not moving, resilient sleeve 3 also is in motionless state like this, therefore, it can move up by relative resilient cover 3, and the lower end of stay cord 4 drives on the movable latch 5 and moves, in motionless outer tube 1 is withdrawn in movable latch 5 ends, just realize folding release, loose one's grip under the effect of retracing spring 6 that movable latch 5 ends are stretched out outside the motionless outer tube 1, and drive stay cord 4 relative resilient cover 3 and move down, realize locking.
When the hand push frame is elongated, movable internal pipe 2 can move up by motionless relatively outer tube 1, movable internal pipe 2 can drive upward, and locating piece 9 moves up, thereby resilient sleeve 3 can be extended automatically owing to the elasticity of self, the stay cord 4 that sets within it also moves on together, in this process, the stay cord 4 that is in movable internal pipe 2 parts is tightened all the time, and stay cord 4 is to move simultaneously with resilient sleeve 3, therefore the relative position between them does not become, so being in the stay cord 4 of resilient sleeve 3 is blocked by resilient sleeve 3 again, so also tighten, whole like this stay cord 4 is elongated in the process at the hand push frame and tightens all the time, wants folding release when putting in place when the hand push frame is elongated, operation is no longer described with last identical.
