Description

Baby carriage frame

[ technical field ] A method for producing a semiconductor device

The invention relates to a baby carriage framework.

[ background of the invention ]

At present, the baby carriage becomes an indispensable article for the growth process of children. The baby carriage in the market can be folded or unfolded generally, but the skeleton structure of the existing baby carriage is very complex, so that the baby carriage is heavy, and people have great labor and inconvenient operation when folding.

Therefore, the present invention has been made in view of the above disadvantages.

[ summary of the invention ]

The invention aims to overcome the defects of the prior art and provides the baby carrier framework which is simple in structure and convenient to operate.

The invention is realized by the following technical scheme:

The locking device of the baby carriage framework comprises a hook 81 arranged on a hinge body 4, and a locking pin which is matched with the hook 81 to keep the baby carriage framework in an unfolded state is arranged on the push rod 3.

The hinge body 4 is provided with a rotating sleeve 9 which can rotate relative to the hinge body, and the push rod 3 passes through the rotating sleeve 9 and can slide in the rotating sleeve 9.

When the stroller frame is unfolded, the upper end of the longitudinal rod 7 is inserted into the hinge body 4.

Compared with the prior art, the invention has the following advantages:

1. the front leg and the rear leg are rotatably connected through the hinge body, so that the lower ends of the front leg and the rear leg can be separated or closed, the push rod is approximately collinear with the longitudinal rod after rotating relative to the hinge body, the push rod can push the longitudinal rod to move downwards, the push rod slides downwards relative to the hinge body, the longitudinal rod pushes the front linkage rod and the rear linkage rod to rotate, and the front linkage rod and the rear linkage rod pull the lower ends of the front leg and the rear leg to be closed and folded. The whole structure is very simple and convenient.

2. The hinge body is provided with the rotating sleeve, the push rod penetrates through the rotating sleeve, the push rod drives the rotating sleeve to rotate together when the push rod rotates, and the push rod can slide downwards in the rotating sleeve when the push rod and the longitudinal rod are approximately collinear, and the arrangement of the rotating sleeve can enable the push rod to slide downwards more stably.

3. The invention has simple structure and convenient operation, and is suitable for popularization and application.

[ detailed description ] embodiments

The invention is further described below with reference to the accompanying drawings:

the baby carriage framework comprises a front leg 1, a rear leg 2 and a push rod 3, wherein wheels 20 are connected to the front leg 1 and the rear leg 2, a hinge body 4 for enabling the front leg 1 and the rear leg 2 to be connected in a rotating mode is arranged between the front leg 1 and the rear leg 2, the lower end of the push rod 3 is inserted into the hinge body 4 and can rotate relative to the hinge body 4 and slide up and down in the hinge body 4, a front linkage rod 5 is hinged to the middle of the front leg 1, a rear linkage rod 6 is hinged to the middle of the rear leg 2, the front linkage rod 5 is hinged to the rear linkage rod 6, a longitudinal rod 7 which is inclined to the push rod 3 when the baby carriage framework is in an unfolded state is further arranged between the front leg 1 and the rear leg 2, the lower end of the longitudinal rod 7 is hinged to the front linkage rod 5 and the rear linkage rod 6, and the upper end of the longitudinal rod 7 is hinged to the lower end of the push. The front leg 1 and the rear leg 2 are rotatably connected through the hinge body 4, so that the lower ends of the front leg 1 and the rear leg 2 can be separated or closed, the push rod 3 is approximately collinear with the longitudinal rod 7 after rotating relative to the hinge body 4, so that the push rod 3 can push the longitudinal rod 7 to move downwards, the push rod 3 slides downwards relative to the hinge body 4, the longitudinal rod 7 pushes the front linkage rod 5 and the rear linkage rod 6 to rotate, and the front linkage rod 5 and the rear linkage rod 6 pull the lower ends of the front leg 1 and the rear leg 2 to be closed and folded. The whole structure is very simple and convenient.

The locking device of the baby carriage framework comprises a hook 81 arranged on a hinge body 4, and a locking pin (not shown in the figure) which is matched with the hook 81 to keep the baby carriage framework in an unfolded state is arranged on the push rod 3. When the hook 81 engages with the locking pin on the push rod 3, the push rod 3 cannot rotate and therefore the push rod 3 cannot be substantially co-linear with the longitudinal rod, i.e. the push rod 3 cannot push the longitudinal rod 7 downwards, so that the stroller frame remains in the unfolded state. Of course the hook 81 and locking pin could be provided between other two components in a pivotal connection.

The hinge body 4 is provided with a rotating sleeve 9 which can rotate relative to the hinge body, and the push rod 3 passes through the rotating sleeve 9 and can slide in the rotating sleeve 9. When the push rod 3 rotates, the push rod 3 drives the rotating sleeve 9 to rotate together, and when the push rod 3 is approximately collinear with the longitudinal rod 7, the push rod 3 can slide downwards in the rotating sleeve 9, and the arrangement of the rotating sleeve 9 can enable the push rod 3 to slide downwards more stably.

When the baby carriage framework is unfolded, the upper end of the longitudinal rod 7 is inserted into the hinge body 4, so that the baby carriage framework can be kept stable in the unfolded state, and the structure is more compact.

The action principle is as follows:

the hook 81 is first disengaged from the locking pin on the push rod 3, and the push rod 3 can be rotated. The push rod 3 is rotated, when the push rod 3 and the rotating sleeve 9 are vertical, the push rod 3 and the longitudinal rod 7 are approximately collinear, the push rod 3 is pushed downwards at the moment, the push rod 3 and the longitudinal rod 7 can slide downwards relative to the hinge body 4, the longitudinal rod 7 pushes the hinge positions of the hinge positions and the front linkage rod 5 and the rear linkage rod 6, and the front linkage rod 5 and the rear linkage rod 6 pull the lower ends of the front leg 1 and the rear leg 2 to be close and folded. The whole process is very simple to operate and the motion is stable.
