Abstract: An eyeglasses assembly structure is provided, in which assembly slots for joint members are mainly formed on both sides of the eyeglasses frame, and the joint members are pivotally connected therein. Locating members are respectively interposed between upper and lower elastic elements for holding the pivotal connection status of the joint members and the assembly slots. When the joint members are to be detached from the assembly slots, the locating members are pushed into sliding grooves of the joint members, and the upper and the lower elastic elements are pressed to be deflected inward so as to allow the upper and the lower pivots detached from the pivotal connection with the assembly slots. Therefore, temples or strap can be assembled on the rear ends of the joint members and then the eyeglasses patterns can be conveniently transformed according to users' needs.
