Embodiment Construction
[0009] Below with reference to accompanying drawing, the present invention is further described
[0010] The present invention is a dual-brake structure for a stroller, which mainly includes a brake wire casing 3, which is different from the prior art in that: the two ends of the brake wire casing 1 are respectively connected to the left brake assembly box 1 and the right brake assembly box 1. Assembly box 4, the left brake assembly box 1 is provided with a locking compression spring 2, and the locking compression spring 2 is connected with the auxiliary compression spring 5 in the right brake assembly box 4 through the steel wire in the brake wire sleeve 3 . One end of the locking compression spring 2 is connected to one end of the steel wire, and the other end of the locking compression spring 2 is connected to the friction head 6 . The surface of the friction head 6 is covered with friction glue, which can play a good stop effect on the wheel hub.

The invention discloses a double-brake structure of a kid bicycle. The double-brake structure is characterized in that the two ends of a brake steel wire line sleeve pipe are respectively connected with a left brake assembly box and a right brake assembly box; and a locking pressure spring arranged in the left brake assembly box is connected with an auxiliary pressure spring in the right brake assembly box through a steel wire line in the brake steel wire line sleeve pipe. The invention adopts a balanced double-brake structure; after the balanced double brake structure is mounted on a back bicycle frame, an instantaneous stopping effect can be achieved even if a vehicle runs downhill at a high speed, thereby effectively improving the safety performance of a product and increasing the market competitiveness of the product; and compared with the prior art, the product has outstanding substantive characteristics and remarkable progresses.
Description
Technical field: [0001] The invention relates to the technical field of baby carriages, in particular to a double-brake structure of a baby carriage, and in particular to its mechanical connection structure. Background technique: [0002] Comparative document 1, patent number: 200820088086.8, patentee: Zhejiang Chenhui Baby Products Co., Ltd., announcement number: CN201235848, this case discloses "a baby carriage brake mechanism", including two support rods, axles and wheels, two The bottom end of the root support rod is fixedly connected to the axle, and the two ends of the axle are pivotally connected to the wheel. The inner surface of the wheel is fixed with a brake gear centered on the axle hole. A brake control block is arranged between the support rod and the wheel. On the brake control block There is an L-shaped through hole, and the axle passes through the L-shaped through hole. There is a U-shaped pedal tube above the axle. The two arm tubes of the U-shaped pedal ar...
