Abstract

A do-it-yourself ceiling fan with a ceiling lamp has a ceiling frame and a guide head. A control rod can pull a confining inserting rod backwards so as to compress a spring. Thereby, the confining inserting rod is separated from a ceiling frame. The guide head inserts into an inserting seat of the ceiling frame, thereby, the ceiling fan being conductive to the ceiling lamp. By the resilient force of the spring, the resisting ring of the confining inserting rod restores to the original position to prevent the guide head from falling down. When it is desired to package, transfer or store the ceiling fan, the guide head with the ceiling lamp is pulled out from the ceiling fan. In assembly, it is only necessary to insert the guide head of the ceiling lamp into the ceiling frame of the ceiling fan without needing studs, and other tools.

Claims

1. 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;

wherein

a 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.

2. The do-it-yourself ceiling fan with a ceiling lamp as claimed in claim 1, wherein a buckling block is protruded from a middle section of the control rod;

a distal end of the cylinder seat has a notch for being passed through by the buckling block so that the control rod can rotate and is positioned therein.

3. The do-it-yourself ceiling fan with a ceiling lamp as claimed in claim 1, wherein a lower end of the guide head has a threaded portion;

the threaded portion passes through the ceiling lamp;

a nut serves to lock the top end of the ceiling lamp.

4. The do-it-yourself ceiling fan with a ceiling lamp as claimed in claim 1, wherein a lateral side of the ceiling frame has an inserting hole;

a lower side of the inserting hole is locked with a confining piece having a protruding portion which exactly inserts into the through hole so that the guide head is buckled therein;

a side of the guide head coupled to the confining piece has an embedding groove;

after the guide head inserts into a lower end of the ceiling frame, the embedding groove of the guide head exactly resists against the confining piece of the ceiling frame.
