Abstract

The invention relates to a desk lamp with a rotatable lamp shade, which comprises a base frame, a lamp shade holder, the lamp shade and a light source component. The lamp shade can be rotatablely installed on the lamp shade holder; the light source component is fixed in the lamp shade; at least two position clips are arranged at the front end inside of lamp shade, and the lamp shade holder is provided with an elastic buckle relative to the position clips; an outer surface of the rear of the lamp shade is provided with pre and post ring bosses which are contacted with the inner surface of the front end of the lamp shade; the elastic buckle is used for reversely buckling the position clips so that the lamp shade only rotates around the axes of the lamp shade while not falls off. When the lamp rotates, the top of the pre and post ring bosses are contacted with a forming surface of the inner surface of the front end of the lamp shade. The design structure is simple; when the light angle is needed to be adjusted, only the lamp shade is required to be rotated, and then the light source can rotate along with the lamp shade, therefore, the user can conveniently adjust the light to a required angle.

Description

The rotating desk lamp of a kind of lampshade

Technical field

The present invention relates to a kind of desk lamp, be meant the rotating desk lamp of a kind of lampshade especially.

Background technology

The structure of desk lamp mainly comprises base, support, lamp holder and lampshade, support generally adopts dual mode, a kind of is rigid support, but another kind of support is to adopt the metal bellows of free bend to make, adopt the desk lamp variation in moulding of rigid support more, as rack making being become elongated shape, or utilize the cooperation of base, support, lamp holder to form whole structure moulding more attractive in appearance, but the shortcoming of the desk lamp of this employing rigid support is a light regulates dumb, particularly the position of lamp holder generally is fixedly connected, can't regulate; Though and it is flexible to adopt the made desk lamp of wavy metal pipe holder to regulate, in moulding, there is limitation, kind is single, and product does not have new meaning.

Summary of the invention

In order to overcome the deficiencies in the prior art, the invention provides a kind of simple in structure, easy to use, rotating desk lamp of lampshade.

The technical solution adopted in the present invention is:

The rotating desk lamp of a kind of lampshade comprises base support, shade holder, lampshade and light source assembly, and described lampshade is rotating to be installed on the shade holder, and light source assembly is fixed in the lampshade; The inboard of lampshade front end is provided with at least two screens, and described shade holder is being provided with the Elastic buckle that can prevent that lampshade from coming off corresponding to screens place; The outer surface at described shade holder rear portion is provided with the forward and backward annular boss that contacts with lampshade front end inner surface; Elastic buckle is lived the screens left-hand thread, and lampshade can only can not be come off around the rotation of the axle center of shade holder; During rotation, forward and backward annular boss top contacts with lampshade front end inner surface formation face.

The invention has the beneficial effects as follows: lampshade is rotating to be installed on the shade holder, light source assembly is fixed in the lampshade, the design is simple in structure, when needs are adjusted the angle of light, only need to rotate lampshade, light source can rotate with lampshade, and the user can adjust to light required angle easily.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the decomposing schematic representation of desk lamp top accessory;

Fig. 3 is the cutaway view of desk lamp top accessory;

Fig. 4 is the another kind of embodiment of desk lamp light source assembly.

The specific embodiment

Referring to figs. 1 through shown in Figure 3, the rotating desk lamp of a kind of lampshade comprises base 1 support 2, shade holder 3, lampshade 4 and light source assembly, lampshade 4 rotating being installed on the shade holder 3, and light source assembly is fixed in the lampshade 4.The inboard of lampshade 4 front ends is provided with two screens 41, shade holder 3 is provided with Elastic buckle 31 in the position corresponding to screens 41, when assembling, the front end that lampshade has screens is inserted in outside the shade holder, Elastic buckle 31 is lived screens 41 left-hand threads, and lampshade can only can not come off around the rotation of the axle center of shade holder.

The outer surface at shade holder 3 rear portions is provided with the annular boss 32 that contacts with lampshade 4 front end inner surfaces, annular boss 32 is forward and backward respectively to be provided with one, make the contact-making surface of rotatable parts stressed more reasonable, the design of annular boss has simultaneously also improved the intensity of shade holder force part.

According to the difference of the light source that is disposed, the design's light source assembly can be a various ways:

When using the LED lamp, light source assembly comprises that the circuit board of LED lamp 51, installation LED lamp 51 also is pcb board 52 and reflector 53, and pcb board 52 is installed on reflector 53 back sides, and reflector 53 is provided with some through holes 54, LED lamp 51 stretches out from through hole 54, and reflector 53 is fixed in the lampshade 4.

When using power saving fluorescent lamps, as shown in Figure 4, light source assembly comprises power saving fluorescent lamps 61, and the lamp holder 62 and the reflector 63 of power saving fluorescent lamps 61 is installed, and lamp holder 62 is installed in the reflector 63, and reflector 63 is fixed in the lampshade 4.Power saving fluorescent lamps can use socket type, also can adopt the screw energy-saving lamp pipe.

For the structure that makes product more reasonable, the present invention is provided with positioning convex 33 at the top of shade holder 3, two inboards of lampshade 4 front ends are respectively equipped with draw-in groove 42, the user is in the rotary lampshade process, when reaching certain angle, the lampshade front end wherein draw-in groove of a side is subjected to the constraint of positioning convex 33, and lampshade can not impacted power line or mains connection because of angular turn is excessive, thereby the raising security of products, this concrete limited angular can design as required.

The above is the preferred embodiment of the present invention, and it does not constitute limiting the scope of the invention, so long as realize that with essentially identical means purpose of the present invention all should belong to protection scope of the present invention.
