Abstract
The utility model relates to a retractable ceiling lamp in which a lampshade can be connected to a lamp holder by a retractable bolt, so that lamp bulbs are convenient to replace and the lampshade also can be prevented from dropping. According to the retractable ceiling lamp, screw holes are formed at upper and lower ends of an inner hole of a screwed pipe, and the diameter of each screw hole is smaller than that of the inner hole; the diameter of a thread head of a screw is greater than that of a rod part of the screw; the screwed pipe and the screw form the retractable bolt commonly; the lamp holder is connected to a roof, and the lamp bulbs are connected to the lamp holder; the screwed pipe is connected with the lamp holder by a connecting disc; and the thread head of the screw penetrates through a central hole of the lampshade, the screw hole at the lower end of the screwed pipe and the inner hole of the screwed pipe sequentially, and is connected with the screw hole at the upper end of the screwed pipe. During use, the thread head of the screw is separated from the screw hole at the upper end of the screwed pipe by rotating the screw, the screw and the lampshade move downwards along the inner hole of the screwed pipe, and when the screw hole at the lower end of the screwed pipe stops the thread head of the screw from moving downwards, the lamb bulbs connected to the lamp holder can be replaced conveniently; and when the lampshade is needed to be disassembled, the thread head of the screw is screwed out of the screw hole at the lower end of the screwed pipe.
Description
Technical field
The utility model relates to a kind of lamp affixed to the ceiling, especially can lampshade be connected on the lamp socket through retract bolt, thereby either be convenient to or change the bulb but also can prevent the telescopic lamp affixed to the ceiling that lampshade comes off.
Background technology
At present, known lamp affixed to the ceiling is with plain bolt lampshade to be connected on the lamp socket, and need take off lampshade when more changing the bulb, therefore not only inconvenience but also dangerous.
Summary of the invention
Not only be not easy to change bulb but also can not prevent the deficiency that lampshade comes off in order to overcome existing lamp affixed to the ceiling; The utility model provides a kind of telescopic lamp affixed to the ceiling; This telescopic lamp affixed to the ceiling can be connected lampshade on the lamp socket through retract bolt, thereby either be convenient to or change the bulb but also can prevent that lampshade from coming off.
The utility model solves the technical scheme that its technical problem adopted: the utility model comprises lamp socket, bulb, lampshade, screwed pipe, screw rod and tie-plate.Screwed pipe is a tube-shaped structure, and the two ends up and down of screwed pipe endoporus all are set to screw, and the diameter of screw is provided with tie-plate less than the diameter of endoporus in the upper end of screwed pipe, and screw flight head diameter is greater than the diameter of its bar portion, and screwed pipe and screw rod constitute retract bolt jointly.Lamp socket is connected on the roof, and bulb is connected on the lamp socket, and screwed pipe is connected with lamp socket through tie-plate, and the screw flight head passes the centre bore of lampshade, the screw of screwed pipe lower end and the endoporus of screwed pipe in proper order and is connected with the screw of screwed pipe upper end.In the use; Through rotary screw its thread head is separated with the screw of screwed pipe upper end; And let screw rod and lampshade move down along the endoporus of screwed pipe, when the screw of screwed pipe lower end stops the screw flight head to continue to move down, can change the bulb that is connected on the lamp socket easily.When needs take off lampshade, the screw flight head screwed out from the screw of screwed pipe lower end get final product.
The beneficial effect of the utility model is, can lampshade be connected on the lamp socket through retract bolt, thereby either be convenient to or change the bulb but also can prevent that lampshade from coming off.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the complete section figure of the utility model.
Fig. 2 is the enforcement illustration of Fig. 1.
Fig. 3 is the complete section enlarged drawing of the utility model retract bolt.
Among the figure: 1. lamp socket.2. bulb.3. lampshade.4. screwed pipe.5. screw rod.6. tie-plate.
The specific embodiment
In Fig. 1, Fig. 2, Fig. 3; Screwed pipe 4 is a tube-shaped structure; The two ends up and down of screwed pipe 4 endoporus all are set to screw, and the diameter of screw is provided with tie-plate 6 less than the diameter of endoporus in the upper end of screwed pipe 4; The thread head diameter of screw rod 5 is greater than the diameter of its bar portion, and screwed pipe 4 constitutes retract bolts jointly with screw rod 5.Lamp socket 1 is connected on the roof, and bulb 2 is connected on the lamp socket 1, and screwed pipe 4 is connected with lamp socket 1 through tie-plate 6, and the thread head of screw rod 5 passes the centre bore of lampshade 3, the screw of screwed pipe 4 lower ends and the endoporus of screwed pipe 4 in proper order and is connected with the screw of screwed pipe 4 upper ends.In the use; Through rotary screw 5 its thread head is separated with the screw of screwed pipe 4 upper ends; And let screw rod 5 and the endoporus of lampshade 3 move down along screwed pipe 4, when the screw of screwed pipe 4 lower ends stops the thread head of screw rod 5 to continue to move down, can change the bulb 2 that is connected on the lamp socket 1 easily.When needs take off lampshade 3, the thread head of screw rod 5 screwed out from the screw of screwed pipe 4 lower ends get final product.
