Abstract:
A do-it-yourself ceiling fan with a ceiling lamp having a ceiling frame in a switch box of a ceiling fan, and a guide head at a top of a ceiling lamp; the guide head being exactly inserted into the ceiling frame; whereina center of the ceiling frame has a through hole; a top thereof is vertically extended with a receptacle with an electric wire passing through the receptacle; the receptacle is exactly coupled to the through hole at a center of the ceiling frame; two sides of the ceiling frame have lateral holes; the through hole communicates the two lateral holes; a lower end of the ceiling frame is horizontally extended with a supporting plate and a confining structure is installed above the supporting plate; the confining structure is formed by a hollow cylinder seat above the supporting plate, a control rod passing through the cylinder seat; a spring installed to the control rod; a confining inserting rod locked to a front of the control rod; a buckling block is protruded from a middle section of the control rod; a front end of the control rod has a threaded section; the control rod passes through the cylinder seat and the spring; then the control rod is locked to a distal end of the confining inserting rod so as to confine the spring to an interior of the cylinder seat and the confining inserting rod is pulled at the same time; a distal end of the cylinder seat is installed with a notch for being inserted by the buckling block of the control rod; a front section of the confining inserting rod is a forked rod which are extended to two lateral holes at two sides of the ceiling frame and meanwhile resists against the lateral wings of the guide head for preventing the guide head from falling down; the confining inserting rod has a resisting ring coupled to a distal end of the control rod; the resisting ring exactly resists against the lateral side of the spring; thereby, when the confining inserting rod pulls backwards with the control rod, the resisting ring exactly compresses the spring so that the confining inserting rod is separated from the guide head; a lower end of the guide head passes through the ceiling lamp in advance; a lateral side of the guide head has lateral wings with respect to the lateral holes and capable of inserting into the lateral holes; the confining inserting rod is installed between the two lateral holes; the confining inserting rod is inserted into the inserting space; after the guide head is inserted into the ceiling frame; a plug at a top thereof exactly inserts into the receptacle; and thereby, a user can assemble the ceiling fan with the ceiling lamp by himself or herself for reducing a storage volume.
