Supporting frame assembly having inclination adjustment mechanism

摘要

A supporting frame assembly includes a first module and a second module pivotally connected to the first module. The first and second modules each include a main body, a pair of aligned knuckles formed on one long side of the main body, a pair of aligned pivot pins formed on an opposite long side of the main body, a lock portion formed between the pivot pins, and a sliding block slidably connected to the top of the main body. The sliding block of the first module is movable along the top of the main body between a first position and a second position with respect to the lock portion of the second module. When the sliding block of the first module is located at the second position, the sliding block is fixedly engaged with the lock portion of the second module to limit rotation between the first and second modules.

1. A supporting frame assembly comprising:
a first module; and a second module pivotally connected to the first module; wherein each of the first and second modules comprises an elongated main body, a pair of aligned knuckles formed on one long side of the main body, a pair of aligned pivot pins formed on an opposite long side of the main body, a lock portion formed between the pivot pins, and a sliding block slidably connected to the top of the main body; wherein the pivot pins of the second module are rotatably supported by the knuckles of the first module, and the sliding block of the first module is movable along the top of the main body of the first module between a first position and a second position with respect to the lock portion of the second module; and wherein when the sliding block of the first module moves from the first position to the second position, the sliding block of the first module moves towards the lock portion of the second module; and when the sliding block of the first module is located at the second position, the sliding block of the first module is fixedly engaged with the lock portion of the second module to limit rotation between the first and second modules.
