[0021] A triangular plate 3 is fixedly connected to the outside of the connection part between the workbench 1 and the support frame 2. A triangular plate 3 is also fixedly connected to the right angle inside the top end of the support frame 2. The setting of the triangular plate 3 makes the connection part between the workbench 1 and the support frame 2 and the structure of the support frame 2 more stable, and extends the service life of the middle axis folding device.

[0022] An installation hole is provided at the middle part of the top end of the support frame 2. A hydraulic press 4 is movably connected to the middle part of the top end of the support frame 2 through a first bolt 5, and the first bolt 5 is inserted into the installation hole. A control panel 17 is movably connected to one side of the support frame 2. The hydraulic press 4 is movably connected to the top end of the support frame 2 through the first bolt 5, so that it can be replaced when the hydraulic press 4 fails, ensuring the working efficiency of the middle axis folding device. The control panel 17 makes the operation of the middle axis folding device more convenient.

[0023] One end of the hydraulic press 4 is fixedly connected with a connecting plate 6. A fixing block 7 is fixedly connected to the bottom end of the connecting plate 6. A pressing block 8 is fixedly connected to the bottom end of the fixing block 7. The pressing block 8 is set in a triangular shape. The folding angle at the top of the pressing block 8 is the same as the angle to be folded of the middle axis. Middle axis grooves 9 are provided on both sides of the middle part of the pressing block 8. By setting the middle axis grooves 9, it can, to a certain extent, avoid excessive changes at the bending part and affect the strength of the middle axis bending part. Connecting cylinders 12 are fixedly connected to both sides of the fixing block 7 at both ends of the connecting plate 6. The connecting cylinders 12 are slidably connected to the outer wall of the guiding rods 11. The connecting cylinders 12 are fixed on the connecting plate 6, enabling the connecting plate 6 to move along the track specified by the guiding rods 11. And a through groove is provided at the top end of the connecting cylinder 12 and located inside the connecting plate 6. The diameter of the provided through groove is a little larger than the diameter of the guiding rods 11, and the guiding rods 11 can pass through the through groove.

[0024] An induction device is provided at the top of the limit rod 10. The top of the limit rod 10 is fixedly connected to a guide rod 11. The top of the guide rod 11 is inserted and connected into a connecting cylinder 12. The top of the mounting seat 13 is fixedly connected to a cushion block 15.

The sum of the heights of the limit rod 10 and the connecting cylinder 12 is equal to the sum of the heights of the mounting seat 13, the cushion block 15, the fixed block 7, and the pressing block 8 when the pressing block 8 and the cushion block 15 are in mutual contact. Such a setting can prevent the pressing block 8 from moving downward too much and causing damage to the central axis to be bent and the cushion block 15.

[0026] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a central axis bending device for a baby carriage of the present invention is specifically a device for bending the central axis of a baby carriage by setting a workbench 1, a support frame 2, a triangular plate 3, a hydraulic press 4, a first bolt 5, a connecting plate 6, a fixed block 7, a pressing block 8, a central axis groove 9, a limit rod 10, a guide rod 11, a connecting cylinder 12, a mounting seat 13, a second bolt 14, a cushion block 15, a groove 16, and a control panel 17. To a certain extent, it replaces manual labor, realizes semi-mechanization, reduces the physical consumption of workers, and improves the working efficiency of workers.

[0027] Working principle of the present invention:

[0028] When it is necessary to bend the central axis of the baby carriage, first control the hydraulic press 4 on the control panel 17 to raise the connecting plate 6, and then drive the pressing block 8 to rise. Place the central axis to be bent on the cushion block 15, adjust the length of the central axis to a suitable position, and then start the hydraulic press 4 on the control panel 17 to bend the central axis of the baby carriage. When the pressing block 8 on the hydraulic press 4 is in mutual contact with the groove 16 on the cushion block 15, the connecting cylinder 12 just touches the top of the limit rod 10. Then, the induction device at the top of the limit rod 10 will control the hydraulic press 4 to raise the pressing block 8, and the worker then replaces the central axis of the baby carriage and repeats the above steps to process the other end.
