    摘要: An automatic lock mechanism is provided for locking adjustable frame system components together. A locking mechanism includes a locking pin having a shaft, a head and a biasing spring cooperates with a stud and slot locking mechanism. A stud is inserted into a slot, for example, a teardrop shaped slot, and then moved to the direction of insertion. The locking pin then extends into slot, preventing inadvertent upward movement of the horizontal member.

    摘要: A built-up screen coupling structure, comprising at least two screen board frames side matched together by a plurality of fastening devices and at least an adjusting device. The screen board frames have each at least a side end having a slot at the top and a plurality of relatively smaller openings at the outer side. The openings are respectively divided by a plurality of dividing boards. The fastening devices are respectively fastened in the openings and clamped on the dividing boards to connect two screen board frames together. The adjusting device is fastened in the slot to secure the connection.
