Abstract

The utility model relates to a lamp which comprises a lamp cover 16 which is connected with a base 12 through the relative sliding members 20, 22. The sliding members can keep the physical and the electrical connection through the first and the second fixing device. Each devices is included in the slots 64, 66 which have electric surfaces and are formed on a member; in the pin which is formed on the other member, arranged in the slot, connected with the surface, and makes relative sliding.

Description

Lamp

The utility model relates to a kind of lamp.

According to the utility model, a kind of lamp that has supporter is provided, this supporter comprises the member that first and second can slide relatively, these two members keep the physics contact and are electrically connected by first and second fixture, and wherein each fixture all comprises a groove and a pin, and groove forms on a member, and a conductive surface is arranged, pin then forms on another member, with being placed in the groove, does relative slip in contact with described conductive surface; One by supporter supports and be electrically connected on light source on described two fixtures; And the device that described device is connected with power supply.

The advantage of the lamp that constitutes according to the utility model is, an adjustable supporter can be provided, this supporter is made up of some members that can do to slide relatively, and the fixed mechanism of these members can make between member getting in touch on the connection that keeps physically and the electricity, thereby no longer needs independent physics to be connected with electricity.

Below by the example in the accompanying drawing, preferred embodiment of the present utility model is described.In the drawings:

Fig. 1 is the perspective view of the embodiment of the present invention on primary importance;

Fig. 2 is similar to Fig. 1, is the perspective view of the embodiment of the embodiment of the invention on the second place (expanding location);

Fig. 3 be Fig. 1 with Fig. 2 in two of lamp can relative sliding support member side view;

Fig. 4 is the view along arrow 4 ' direction among Fig. 3;

Fig. 5 is the cutaway view by S ' among Fig. 4-S plane.

With reference to Fig. 1 and 2, numbering 10 has been represented a lamp.This lamp comprises base 12, and it has a cavity (not shown) that is used for packed battery, and switch 14 is connected with base 12, the lampshade 16 that has a bulb 18 by first and second arc slidably member 20,22 be connected under the base.In use, slidably member can be done relative slip, so that lamp extends to position for example shown in Figure 2.Slidably the arch section 40 of member 20,22 and the base 12 that matches with member 20 slidably all has complementary slidingsurface, on the surface protuberance is arranged, the groove that is mated is then arranged on the apparent surface of another member, one protuberance 30 is for example arranged on the member 20, and it is meshed with groove 32 on the member 22; Equally, member 12 has a protuberance 34 be meshed with groove 36 (Fig. 3).By fixed mechanism with these slidably parts combine, Fig. 3-5 illustrates in greater detail fixed mechanism.

For the sake of clarity, Fig. 3-5 shows slidably member 20 and base 12.The arch section 40 of base 12 comprises first and

second pin

50,52, and they are connected an end of protuberance 34.These two pins are arranged in the

respective grooves

54,56, and can slide along them, and wherein

groove

54,56 is in the both sides of the recess 36 of member 20.If wish to strengthen support, can on protuberance 34, increase some grooves again, correspondingly with it respective pins also is set, as " the empty pin " 51 that is shown in dotted line among Fig. 3 at recess 36 1 ends.

50,52 joins by the power supply on

lead

60,62 and the base 12.Further, in each

groove

54,56, all there is not

metal track

64,66, so that match with the suffered pin of receiving 50,52 in the corresponding groove with being close to, and can CONTACT WITH FRICTION when pin moves in

groove.Metal track

64,66 is connected with the

70,72 of member 20 successively by

lead

74,76.

So the positive and negative electrode of battery supply and selling accordingly between 70,72 in base 12 has formed electrical connection.Slidably member 22 has some grooves and the metal track identical with member 20, but the metal track of member 22 is not further to link on the pin, but links on the lamp 18 by the lead (not shown).

Therefore, by the effect of pin and metal track, just can be electrically connected to forming between the bulb 18 of lampshade 16 at the power supply of base 12, member 20,22 no longer needs independent physics to connect with electricity thereby make slidably.

In use, if desired with lamp, for example be stretched over position shown in Figure 2 from position shown in Figure 1, pin is done relative slip with groove guiding elements 20,22, simultaneously, by the CONTACT WITH FRICTION between the metal track in pin and the groove, can make lamp and power supply keep being electrically connected.
