Description

A kind of desk lamp

Technical field

This utility model relates to a kind of desk lamp.

Background technology

Lamp has become as requisite component in the daily household of people, and wherein desk lamp also plays a very important role.The illumination zone of desk lamp is little so that illumination is smaller on the impact of environment, is particularly well suited for use in desk and the head of a bed so that while user obtains illumination, and the people's impact on periphery also is able to effectively be controlled.But tradition desk lamp still has its limitation, the lampshade of tradition desk lamp is to immobilize, the bulb area that namely lampshade is covered is certain, so exiting surface of bulb i.e. certain, user cannot change the lighting area of bulb according to actual needs, in some cases, the people of surrounding still can be brought impact and puzzlement by bigger lighting area.

Utility model content

Technical problem underlying to be solved in the utility model is to provide a kind of desk lamp, it is possible to the size of unrestricted choice desk lamp exiting surface, thus does not interferes with the people of surrounding.

In order to solve above-mentioned technical problem, this utility model provides a kind of desk lamp, including a lamp socket, bulb and the first lampshade；Described bulb and the first lampshade are fixing with described lamp socket respectively to be connected, and bulb and the first lampshade are coaxially disposed；Described first lampshade has a hemispheric containing cavity, and described containing cavity is coated on the rear quarter surface of described bulb；

The second lampshade and the 3rd lampshade it is additionally provided with in the containing cavity of described first lampshade, two ends with the first lampshade respectively, its two ends are rotationally connected, when rotating described second lampshade or three lampshades in the horizontal direction, the front hemisphere surface portion of described bulb is blocked by described second lampshade or the 3rd lampshade.

In a preferred embodiment: described second lampshade and the 3rd lampshade are also hemispherical, and the second lampshade and the 3rd lampshade and the first lampshade are coaxially disposed.

In a preferred embodiment: there is on described lamp socket a connection post vertical with lamp socket.

In a preferred embodiment: the outer surface of described connection post is arranged at intervals with 4 ring ribs；3 limiting sections are formed between described raised line and raised line.

In a preferred embodiment: described first lampshade, the second lampshade, same one end of the 3rd lampshade are respectively equipped with the first installing hole, and described first installing hole completes to be co-axially mounted in being plugged to described 3 limiting sections respectively.

In a preferred embodiment: described connection post also has the jack of a hollow, the interface that is electrically connected of described bulb electrically connects with the drive circuit in described base after described jack.

In a preferred embodiment: described base is circular, and its upper surface is additionally provided with a switch.

Compared to prior art, the technical solution of the utility model possesses following beneficial effect:

A kind of desk lamp that this utility model provides, user manually rotates the second lampshade and the 3rd lampshade, the front hemisphere face of bulb can be covered from the left and right sides, it is achieved thereby that change the purpose of bulb exiting surface size, avoid in some cases, owing to the exiting surface of bulb is excessive and have impact on the people of surrounding.

Accompanying drawing explanation

Fig. 1 is the structural blast figure of this utility model preferred embodiment；

Fig. 2 is the assembling schematic diagram of this utility model preferred embodiment.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, this utility model is described further.

With reference to Fig. 1-2, a kind of desk lamp, including a lamp socket 1, bulb 2 and the first lampshade 3；Described bulb 2 and the first lampshade 3 are fixing with described lamp socket 1 respectively to be connected, and bulb 2 and the first lampshade 3 are coaxially disposed；Described first lampshade 3 has a hemispheric containing cavity, and described containing cavity is coated on the rear quarter surface of described bulb 2；

The second lampshade 4 and the 3rd lampshade 5 it is additionally provided with in the containing cavity of described first lampshade 3, two ends with the first lampshade 3 respectively, its two ends are rotationally connected, when rotating described second lampshade 4 or three lampshades 5 in the horizontal direction, the front hemisphere surface portion of described bulb 2 is blocked by described second lampshade 4 or the 3rd lampshade 5.

User manually rotates the second lampshade 4 and the 3rd lampshade 5, the front hemisphere face of bulb 2 can be covered from the left and right sides, it is achieved thereby that change the purpose of bulb 2 exiting surface size, it is to avoid in some cases, owing to the exiting surface of bulb 2 is excessive and have impact on the people of surrounding.

Concrete structure is as follows:

Described second lampshade 4 and the 3rd lampshade 5 are also hemispherical, and the second lampshade 4 and the 3rd lampshade 5 are coaxially disposed with the first lampshade 3.

In order to realize structure as above, described lamp socket 1 has a connection post 11 vertical with lamp socket 1.The outer surface of described connection post 11 is arranged at intervals with 4 ring ribs 12；3 limiting sections 13 are formed between described raised line 12 and raised line 12.

Same one end of described first lampshade the 3, second lampshade the 4, the 3rd lampshade 5 is respectively equipped with the first installing hole, and described first installing hole completes to be co-axially mounted in being plugged to described 3 limiting sections 13 respectively.Simultaneously as the position-limiting action of ring rib 12.First lampshade the 3, second lampshade the 4, the 3rd lampshade 5 is just limited and in 3 limiting sections, respectively from without influencing each other.

Described connection post 11 also has the jack of a hollow, and the interface that is electrically connected of described bulb 2 electrically connects with the drive circuit in described base 1 after described jack 11.

In the present embodiment, described base 1 is circular, and its upper surface is additionally provided with a switch.

The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with scope of the claims.
