1. Field of the Invention
This invention relates to a decorative lamp, and particularly to a figurative structure for clamping a decorative lamp string.
2. Description of the Prior Art
In the conventional decorative lamp string for Christmas season, a plurality of sockets are mounted therein by using two or more than two power wires twisted together to connect such sockets in series; such a lamp string is subject to swinging or hanging in the air because of the sockets thereof not being fastened in place.
In the conventional decorative lamp string for a given festival, the figurative lamp-mounting frame is usually made of a metal, on which a plurality of socket assemblies connected in series with twisted power wires are mounted thereon. The power wires and the figurative lamp-mounting frame are usually not fastened together; as a result, the lamp string and the lamp-mounting frame are subject to separating from each other. Some of such lamp strings may be fastened in place with fastening cord; however, the sockets and the power wires are also subject to swinging and hanging in the air.
In the conventional decorative lamp string for Christmas season, please reference the U.S. Pat. No. 4,802,072, it is a direction fixture for decorative lamp series comprising a socket for a bulb, wires connected to said socket and a retaining ring attached to said socket, said retaining ring being provided with a notch extending longitudinally of the socket with the wires that are connected to said socket being positioned and retained in said socket so as to fixed said socket in a desired orientation and wherein said retaining ring has an outer face which is in registry with an end rim of said socket. In the aforesaid invention, the socket assemblies and the power wires are fastened in place with fastening slips, but the socket assemblies and the power wires appear to be out of order; therefore, the lamp string has to be fastened to a lamp-mounting frame with fastening cords.
In another conventional lamp string for Christmas season, please reference the U.S. Pat. No. 5,526,246, the front part of the figurative structure is provided with a fastening base, which is furnished with a plurality of hooks for clamping sockets respectively; then, the sockets are fastened to the figurative structure. When the bulbs wink, the figurative structure will be shown vividly. The back of the figurative structure is provided with a connection plate; as a result, such figurative structure can only be used for one-side decoration.
In still another conventional lamp string for Christmas season, such as U.S. Pat. No. 5,727,872, the bulb-plugging end of the socket assembly has two curved surfaces on both sides thereof, and one side thereof has two symmetrical arm plates extended out; the tail ends of such arm plates have two curved hooks respectively; the inner surface of the hooks each have a curved surface to fit to the figurative lamp-mounting frame. The outer ends of the two hooks form into an opening; each socket assembly has two arm plates to form into an opening so as to click to the metal rod of the figurative lamp-mounting frame, i.e., to have the socket assembly clamped to the metal rod of the figurative lamp-mounting frame.
