Abstract

The utility model discloses a table lamp multi-angle swinging device which comprises a lower arm and an upper arm. A universal node is movably connected with the top of the lower arm. A connecting sleeve is connected with the upper end of the universal node. The connecting sleeve is further connected with the upper arm. A notch is formed in the top of the universal node. A screw hole is formed in the side wall of the connecting sleeve. The upper end of the universal node is screwed in the connecting sleeve through threads, a screw is screwed in the screw hole, rotation smaller than 360 degrees can be conducted by threaded connection between the universal node and the connecting sleeve through the coordination of the screw and the notch, and the threaded connection between the universal node and the connecting sleeve can not be loosened. The table lamp multi-angle swinging device is simple in structure, ingenious in design, low in production cost and long in service life.

Description

Desk lamp multi-angle pendulous device
Technical field
The utility model relates to desk lamp, relates in particular to a kind of desk lamp multi-angle pendulous device.
Background technology
Desk lamp is people's daily household electrical appliance, as being placed on desk, workbench or other place instrument as illumination.Traditional desk lamp is made of lampshade, arm and lamp socket mostly, incandescent lamp is installed in lampshade then, yet this its volume of class desk lamp is big, arm scarcely possesses folding, spinfunction, thereby, the occupation space area is big during collection, and the direction of illumination when using, position can not free adjustment, use inconvenient.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provide a kind of simple in structure, design is ingenious, production cost is low, long service life, easy to use, angle can freely regulated desk lamp multi-angle pendulous device.
The technical scheme that its technical problem that solves the utility model adopts is:
Desk lamp multi-angle pendulous device, comprise underarm and upper arm, the top movable of described underarm is connected with universal joint, the upper end of universal joint connects adapter sleeve, adapter sleeve is connected with upper arm again, the top of described universal joint has breach, the sidewall of described adapter sleeve has screw hole, the upper end of universal joint is screwed in the adapter sleeve by screw thread earlier, be screwed into screw in the screw hole again, by cooperating of screw and breach, make being threaded between described universal joint and the adapter sleeve can do rotation, and universal joint can not come off with being threaded of adapter sleeve less than 360 degree.
The lower end of described underarm is fixed on the lamp socket, the lower end of described universal joint can be the center with the central shaft of underarm, work is less than the rotation of 360 degree, the upper end of described universal joint can swing up and down 90 degree, upper arm can be the center with the central shaft of upper arm, work also is equipped with lamp and circuit board less than the rotation of 360 degree on described upper arm.
The beneficial effects of the utility model are: the utility model design is ingenious rationally, the rotation less than 360 degree can be done in the lower end of described universal joint, the upper end of universal joint can swing up and down 90 degree, and upper arm also can be realized rotations less than 360 degree by turning adapter sleeve, but this product structure is simple, design is ingenious, angle free adjustment, low, the long service life, easy to use of production cost.
