[specific embodiment]
Be described in further detail below in conjunction with accompanying drawing and embodiments of the present invention: referring to
Fig. 1-5, the present invention is a kind of Foldable baby stroller frame, includes:
Movable part 1 before one respectively is provided with a preceding slide opening 11 at its both ends;
The one back movable part 2 that can separate or be fitted together with preceding movable part 1, slide opening 21 after its both ends respectively are provided with one, are being provided with the latching device 9 that they are locked together between back movable part 2 and preceding movable part 1;
Support tube 3 before two, its front end is hinged with front vehicle wheel after passing two preceding slide openings 11 respectively, the rear end of support tube 3 is hinged on the bottom of back movable part 2 before two, and two hinge-points are arranged side by side and after two between the slide opening 21, and the front end of support tubes 3 relatively outwards separates at preceding movable part 1 with when afterwards movable part 2 connects before two;
Two rear supporting tubes 4, after passing two respectively, its rear end is hinged with rear wheel behind the slide opening 21, the rear end of movable part 1 before the front end of two rear supporting tubes 4 is hinged on, and two hinge-points are arranged side by side and between two preceding slide openings 11, and relatively outwards separate at preceding movable part 1 with when afterwards movable part 2 connects the rear end of support tubes 4 before two;
One crossbeam 5, wherein subordinate's end is provided with sleeve pipe 51;
Folding stand 6 before one, it is connected between preceding movable part 1 and the crossbeam 5;
One back folding stand 7, it is connected between back movable part 2 and the crossbeam 5;
One push tube 8, this push tube 8 is fixed in the described sleeve pipe 51, and push tube 8 front ends be hinged on before on the movable part 1, on push tube 8, be equipped with and drive the unlock rope that latching device 9 is unblanked.During use, with pulling moving unlock rope, it drives latching device 9 and unblanks, at this moment, preceding, be not fixed together between the back movable part, with the subordinate push tube 8 of pressing, push tube 8 drives crossbeam 5 and moves down together, movable part and back movable part were folding, preceding forward respectively for folding stand 6 and back folding stand 7 before crossbeam 5 pressed, back movable part separates, and is preceding, back movable part respectively forward, move the back, preceding movable part reach, two preceding slide openings 11 on it make that the rear end of two rear supporting tubes 4 is close in opposite directions, move behind the back movable part, and slide opening 21 makes that the front end of two preceding support tubes 3 is close in opposite directions after two on it, thereby realize the folding of whole vehicle frame, after above-mentioned folding, elongate front and back behind the whole vehicle frame folding, and chassis frame height reduces, width diminishes, thereby folding back single-piece volume is little, and it is little to take up room, and is convenient to deposit and transport.
Connection pipe 63 before folded tube 61, the two second preceding folded tube 62 and before folding stand 6 comprises two first before described; Connection pipe 63 is fixedly connected between the two first preceding folded tube 61 before described, the two ends, the left and right sides of movable part 1 before the lower end of folded tube 61 is hinged on respectively before described two first, the upper end of folded tube 61 is hinged on the front end of folded tube 62 before two second respectively before two first, and the rear end of two second preceding folded tube 62 is hinged on the left and right sides of crossbeam 5.
Described back folding stand 7 comprises two back folded tube, 71, one back connection pipes 73; Described back connection pipe 73 is fixedly connected between the two back folded tube 71, and the lower end of two back folded tube 71 is hinged on the two ends, the left and right sides of back movable part 2 respectively, and the upper end of two back folded tube 71 is hinged on the left and right sides of crossbeam 5 respectively.
For the ease of fixing between preceding movable part 1 and the back movable part 2, between two rear supporting tubes 4, be provided with sliding sleeve 12 in preceding movable part 1 rear end, movable part 2 front ends are provided with the inserted link 22 that can be inserted in the sliding sleeve 12 in the back.
Described latching device 9 is arranged on the last lockhole 91 on the sliding sleeve 12, the following lockhole 92 that is arranged on inserted link 22 front ends and can aims at last lockhole 91, and be arranged on retracing spring and the latch 93 that can be inserted into successively in lockhole 91, the following lockhole 92 in the preceding movable part 1; Described latch upper end is connected with unlock rope.During release, the pulling unlock rope drives on the latch 93 and moves and leave down lockhole 92 and last lockhole 91, but slide relative between preceding movable part 1 and the back movable part 2.When locking, preceding movable part 1 and back movable part 2 are close together, are inserted into lockhole 91 next time in the effect of retracing spring, down in the lockhole 92, preceding movable part 1 and back movable part 2 just are fixed together.
Described crossbeam 5 comprises in the crossbeam pipe 52 and can be retracted to its in-to-in crossbeam side pipe 53 from crossbeam outer tube 52 two ends respectively.When folding, the crossbeam side pipe 53 of both sides can be retracted to and manage in the crossbeam in 52, reduce vehicle frame single-piece width; Again the crossbeam side pipe 53 of both sides is managed from crossbeam during use in 52 and extract out.
Described push tube 8 comprise be hinged on before on the movable part 1 outer tube 81 and can collapse into interior pipe 82 in the outer tube 81 downwards.When folding, the interior pipe 82 of upside can be retracted in the horizontal outer tube 81, extract out again during use.
Referring to Fig. 6,7, be application drawing of the present invention, 2 bassinet baskets 10 are housed on crossbeam 5.
