Abstract: An eyeglasses assembly structure is revealed. A pivot member which is pivotally connected to a first assembly portion of a frame is inserted and mounted in a switch member. A first rib and a second rib are opposite to each other and disposed on a second assembly portion at a front side of a temple. The first rib is mounted into a first mounting groove at one end of the pivot member. A positioning flange is formed on the second rib and inserted through an opening of the switch member to be mounted in a second mounting groove on the other end of the pivot member. When the switch member is rotated an angle to be staggered or aligned with respect to the positioning flange of the second rib, the temple is firmly fixed to or separated from the frame. Thereby parts are assembled and replaced easily and conveniently.
