Detailed Description
As shown in fig. 1, 2, 3 and 4, the foldable stand of the present invention comprises a front leg 1, a rear leg 2, a first connecting rod 3 and a second connecting rod 4, wherein the first connecting rod 3 and the rear leg 2 are cross-pivoted by a first pivot 21, the upper end of the second connecting rod 4 is pivoted to the rear end of the front leg 1 by a second pivot 41, and the lower end is pivoted to the lower end of the first connecting rod 3; the front leg 1 is further pivoted to the rear leg 2 by a third pivot 22, and the first pivot 21, the second pivot 41 and the third pivot 22 are pivots at different positions.
Preferably, the third pivot 22 is located above the first pivot 21 and the second pivot 41.
The lower end of the front foot 1 is connected with a front wheel 5, and the lower end of the rear foot 2 is connected with a rear wheel 6.
When the support is folded, the first connecting rod 3 is rotated backwards and downwards, so that the front end of the first connecting rod 3 rotates upwards relatively, the rear end of the front foot 1 is driven to rotate upwards, the front lower end of the front foot 1 rotates backwards to lean against the rear foot 2, and the support is folded until the front foot 1, the rear foot 2, the first connecting rod 3 and the second connecting rod 4 rotate relatively to approach. So, each subassembly of folding in-process support links each other very smoothly for folding operation is very light easy not hard, and folding back volume of material is little moreover.
The utility model discloses baby carriage frame can be changed between expanded state and fold condition, and it includes the support, still includes push handle pole 7, third connecting rod 8, the upper end of first connecting rod 3 and the upper end of third connecting rod 8 are pin-jointed in the different positions of push handle pole 7 respectively, and the lower extreme of third connecting rod 8 is pin-jointed in rear foot 2, thus push handle pole 7, third connecting rod 8, first connecting rod 3 and rear foot 2 form a four-bar linkage; the front foot 1 is pivoted with the third connecting rod 8 through the third pivot 22; alternatively, the front leg 1 is pivotally connected to the lower end of the third link 8 and the rear leg 2 via the third pivot 22. That is, when the lower end of the third link 8 is pivoted to the rear leg 2, the front leg 1 may be pivoted to only the rear leg 2 or only the third link 8 by the third pivot 22, or may be pivoted to both the lower end of the third link 8 and the rear leg 2 by the third pivot 22. In this embodiment, preferably, the front leg 1 is pivotally connected to the lower end of the third link 8 and the front end of the rear leg 2 via the third pivot 22, so that the assembly is more convenient, the structure of the stroller frame is more compact, and the stroller frame is more stable when in the unfolded state.
The upper end of the first link 3 is pivotally connected to the lower end of the push handle rod 7 through a fourth pivot 31, the upper end of the third link 8 is pivotally connected to the push handle rod 7 through a fifth pivot 81, and the fifth pivot 81 is located on the upper side of the fourth pivot 31, so that the push handle rod 7, the first link 3, the third link 8 and the rear leg 2 form a four-link structure.
Preferably, the front leg 1 includes a first section 11 extending from bottom to top and a second section 12 extending from the upper end of the first section 11 to back, and the upper end of the second link 4 is pivotally connected to the rear end of the second section 12. In this embodiment, the second segment 12 is pivotally connected to the front end of the rear leg 2 and the lower end of the third link 8 through the third pivot 22. So set up for the frame is whole more compact, and the volume of timber is littleer after folding moreover. In other embodiments, the first segment 11 may be pivotally connected to the rear leg 2 or/and the third link 8.
It is folding the utility model discloses during the perambulator frame, it is rotatory to go forward push away barre 7 and make push away barre 7 down to move and lean on back foot 2 to drive first connecting rod 3, the 8 upper ends of third connecting rod all down swivelling movement and lean on back foot 2, when the 3 upper ends of first connecting rod down swivelling movement, its lower extreme can be up-rotated relatively, thereby can drive 1 rear end of preceding foot is up-rotated, thereby the preceding lower extreme of preceding foot 1 can be back-rotated and lean on back foot 2 (as shown in figure 3), until push away barre 7, first connecting rod 3, second connecting rod 4, third connecting rod 8, preceding foot 1, back foot 2 and be close to each other, the utility model discloses the perambulator frame is folding completely (as shown in figure 4). Because push away barre 7, first connecting rod 3, third connecting rod 8, back foot 2 form into a four-bar linkage, because four-bar linkage's characteristic, so push away barre 7 and third connecting rod 8's setting, can not influence the smooth and easy of each subassembly linkage of support, thereby the utility model discloses a folding operation is light not hard, and whole receipts are closed in addition and are expected to be long-pending also very little.
In this embodiment, it is preferable that the second section 12 is provided as a seat for sitting. Therefore, when the bicycle frame is folded, the seat part is folded together, so that the folding operation is simpler and more convenient.
In the above description of the orientation, the front wheel 5 is located at the front, the rear wheel 6 is located at the rear, the driver is located at the upper position, and the front wheel 5 and the rear wheel 6 are located at the lower position.
