[0007] One end of the rear support rod (3) is hinged to the lower push rod, and the other end is hinged to the rear bracket;

[0008] The front end of the push handle is hinged to the rear end of the push rod.

[0009] Furthermore, the front bracket and the downward push rod are located on the same plane, and the rear bracket is located outside the front bracket.

[0010] Furthermore, the hinge point between the downward push rod and the front bracket is located behind the hinge point between the rear bracket and the front bracket.

[0011] Furthermore, a fixing block (6) is provided below the front section of the pressing rod, and one end of the rear support rod (3) is hinged to the fixing block.

[0012] Furthermore, a positioning seat (7) is provided at the rear of the rear section of the rear support, and the other end of the rear support rod (3) is hinged to the positioning seat.

[0013] Furthermore, a hinge (8) is installed at the front end of the push handle, and the front and rear ends of the hinge are respectively connected to the push rod and the push handle.

[0014] Furthermore, the front end of the push rod is provided with a positioning block (9) for mounting the baby carrier frame (10).

[0015] Furthermore, a locking element (40) is installed in the middle of the push handle.

[0016] Furthermore, the rear end of the rear support is connected to the rear wheel (14) of the stroller, and the lower front end of the front support is connected to the front wheel (13) of the stroller via the front fork (17).

[0017] With the above solution, the present invention has at least the following advantages: the stroller frame can hold a child basket for the child to lie down and sit in. When the stroller is not needed, the child basket can be removed directly, and then the stroller frame can be folded. After folding, the stroller frame is small in size, can stand up, has a simple structure, is flexible in folding, is convenient and practical, occupies little space, is easy to carry, and can be placed in the trunk of a car or on the overhead luggage rack above an airplane seat.

[0018] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings. Attached Figure Description

[0019] Figure 1 This is a schematic diagram showing the open state of the stroller frame of this utility model;

[0020] Figure 2 This is a schematic diagram of the folded state of the stroller frame of this utility model;

[0021] Figure 3 This is a schematic diagram of the structure of the stroller frame of this utility model in use. Detailed Implementation

[0022] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0023] Example: A stroller frame, with the forward direction of the stroller as the reference, includes a front support 1, a rear support 4, a rear support rod 3, a downward push rod 2, and a push handle 5 arranged symmetrically from left to right;

[0024] The front end of the rear bracket is hinged to the rear end of the front bracket.

[0025] The front end of the downward push rod is hinged to the rear end of the front bracket;

[0026] One end of the rear support rod is hinged to the downward push rod, and the other end is hinged to the rear bracket;

[0027] The front end of the push handle is hinged to the rear end of the push rod.

[0028] Furthermore, the front bracket and the downward push rod are located on the same plane, and the rear bracket is located outside the front bracket.

[0029] Furthermore, the hinge point between the downward push rod and the front bracket is located behind the hinge point between the rear bracket and the front bracket.

[0030] Furthermore, a fixing block 6 is provided below the front section of the downward push rod, and one end of the rear support rod 3 is hinged to the fixing block.

[0031] Furthermore, a positioning seat 7 is provided at the rear of the rear section of the rear bracket, and the other end of the rear support rod 3 is hinged to the positioning seat.

[0032] Furthermore, a hinge 8 is installed at the front end of the push handle, and the front and rear ends of the hinge are respectively connected to the push rod and the push handle.

[0033] Furthermore, the front end of the push rod is provided with a positioning block 9 for mounting the baby carrier frame 10.

[0034] Furthermore, a locking element 40 is installed in the middle of the push handle.

[0035] Furthermore, the rear end of the rear support is connected to the rear wheel 14 of the stroller, and the lower front end of the front support is connected to the front wheel 13 of the stroller via the front fork 17.

[0036] The stroller frame folds as follows: Manually operate the locking mechanism to unlock it, then push the handle downwards. The handle drives the downward-pressing lever to rotate downwards, causing the front support to move backwards and align with the rear support. Simultaneously, the downward-pressing lever moves the rear support rod towards the rear support, pulling the rear support towards the rear support rod, thus completing the folding process. This stroller frame is compact when folded, can stand upright, has a simple structure, folds flexibly, is convenient and practical, takes up little space, and is easy to carry. It can be placed in the trunk of a car or on the overhead luggage rack of an airplane seat.
