Folding and releasing joint and children cart

Abstract

The invention relates to a folding and releasing joint and a children cart. The folding and releasing joint comprises a shell, a base plate fixed in the shell, a first driving sheet and a second driving sheet which are arranged on the base plate and a locking mechanism installed on the base plate; the first driving sheet is provided with a first shaft hole and a first waist-shaped hole, the second driving sheet is provided with a second shaft hole and a second waist-shaped hole, a first rotating shaft penetrating through the first shaft hole and a second rotating shaft penetrating through the second shaft hole are arranged on the base plate, a long hole is vertically and obliquely formed in the base plate, a limiting shaft which can move up and down in the long hole is arranged in the long hole, the limiting shaft is arranged in the first waist-shaped hole and the second waist-shaped hole in a penetrating mode, a first locking groove and a second locking groove which can be overlapped are correspondingly formed in the first driving sheet and the second driving sheet, and the locking mechanism can be inserted into the first locking groove and the second locking groove simultaneously, so that locking of the folding and releasing joint is achieved.

Description

technical field [0001] The invention relates to a folding release joint and a stroller for children. Background technique [0002] In the prior art, a children's stroller includes a stroller frame, a front wheel assembly, and a rear wheel assembly. The stroller frame includes a front wheel bracket, a rear wheel bracket, and a push handle. The rear wheel assembly is arranged on the rear and lower part of the wheel frame. Usually, a connecting rod must be arranged between the front wheel bracket and the rear wheel bracket. When the cart frame is unfolded and folded, the connecting rod drives the front wheel bracket or the rear wheel bracket to enter the folded state. However, due to the large number of rods in this kind of frame, the installation time of the rods is longer and the production cost is relatively high. In addition, when folding or opening, sometimes it will be stuck, and the force required for folding or unfolding is relatively large. [0003] In view of the ab...

[0002] In the prior art, the children's stroller includes a stroller frame, a front wheel assembly, and a rear wheel assembly. The stroller frame includes a front wheel bracket, a rear wheel bracket, and a push handle. The rear wheel assembly is arranged at the rear and lower part of the wheel frame. Usually, a connecting rod must be arranged between the front wheel bracket and the rear wheel bracket. The front end of the connecting rod is rotatably connected with the front wheel bracket. When the cart frame is unfolded and folded, the connecting rod drives the front wheel bracket or the rear wheel bracket to enter the folded state. However, due to the large number of rods in this type of frame, the installation time of the rods is longer and the production cost is relatively high. In addition, when folding or opening, sometimes it will be stuck, and the force required for folding or unfolding is relatively large
