Abstract
The utility model discloses a connecting device for tent frames. The connecting device can be connected between two foldable supporting rods, and the inner end parts of the two struts are in rotary connection relation. The connecting device comprises a first connecting part, a second connecting part and a locking bolt. The first connecting part is arranged on a first strut, wherein a first locking hole with the axis coinciding with the first strut is arranged on the first connecting part. The second connecting part is arranged on a second strut, wherein a second locking hole with the axis coinciding with the second supporting rod is arranged on the second connecting part. The locking bolt is detachable inserted in the first locking hole and the second locking hole. As the locking bolt is detachable inserted in the first locking hole and the second locking hole, after the two supporting rods are unfolded, the insert connection between the locking bolt and the two locking holes can limit the relative rotation of the two supporting rods, and is reliable, stable and firm in rotation limit; and the two supporting rods can freely rotate after the locking bolt is pulled out so as to separate from either locking hole.
