CROSS REFERENCE TO RELATED APPLICATION

This application claims priority benefit of Chinese Patent Application No. 202321081614.8, filed on May 8, 2023, and the entire content of which is incorporated herein by reference.

TECHNICAL FIELD

The disclosure relates to the technical field of tent frames, and in particular to a tent frame.

BACKGROUND

The tent frame, a type of canopy supported on the ground to shelter from wind, rain, and sunlight for temporary living, is typically made of canvas. It can be detached and transferred freely together with supporting parts. The tent frame is carried in parts and assembled on site. Accordingly, a variety of parts and tools are required, and knowledge about the name and use method of each part, and the configuration of the tent frame is required in order to rapidly and conveniently set up the tent frame.

In the prior art, a tent frame is disclosed in Chinese Patent No. 202210422003.9. The tent frame includes upright posts and a canopy mechanism, where a first limiting mechanism matches a middle connection seat and a lower connection seat and limits a minimum distance between the middle connection seat and the lower connection seat; and a second limiting mechanism limits a maximum upward rotation angle of a connection rod, a tail end of the connection rod at a maximum rotation angle is arranged obliquely upwards, so that downward included angle A between connection rods of two opposite tent rod groups is greater than 180 degrees. In this case, the tent frame is self-locked at an angle greater than 180 degrees, and then kept in an unfolded state. After the middle connection seat is lifted upwards, a downward included angle between connection rods of every two opposite tent rod groups is smaller than 180 degrees, and then the tent frame is self-unlocked. However, the tent frame is stressed intensely and unevenly when being unfolded, and will become unstable after being unfolded. Moreover, without a guide structure, the tent frame is likely to deviate when being pushed upwards and unfolded and less stable accordingly.
