Abstract
The utility model belongs to the technical field of eyeglasses, and relates to a connection structure of eyeglasses earpiece and eyeglasses frame. A connection base is provided with an axial blind hole; the opening end of the blind hole, on the connection base, is provided with a reduced section part; two opening sides on the end face of the opening end of the blind hole on the connection base symmetrically extend outwards to form two U-shaped shaft brackets, a lateral opening communicated with the blind hole is formed in the lateral face perpendicular to the axis of the connection base; an elastic locking device is arranged in the blind hole of the connection base, and a telescopic rod of the elastic locking device stretches out of the space between the two shaft brackets. Advantageously, the elastic locking device of the connection structure can limit the tightness of connection between an eyeglasses earpiece and an eyeglasses frame in a constant range under the influence of expansion degree of a spring, so that inconvenience to the users caused by too loose or too tight connection is avoided; the connection structure is simple, convenient to connect and dismount, and suitable for various eyeglasses.
