This embodiment provides a reduce frictional force's flexible lamp, including

screw lamp holder

1, 1 lower extreme of screw lamp holder be connected with the upper end of last lamp body 2 for being connected of lamp body and lamp stand. Go up lamp body 2 and contact through the clearance that sets up between two adjacent arris 31 of the outside bellied arris of last lamp body 2 outer surface and well lamp body 3, a position for fixing last lamp body 2, in order to realize keeping lamp body 2 and well lamp body 3 relative parallel translation to keeping among the flexible process, the availability factor of the flexible lamp of reinforcing, simultaneously at flexible in-process, the bottom side of going up the lamp body can with the surface contact of the inside arris of well lamp body, thereby avoid the problem that the bottom side of current last lamp body can with the direct surface contact of well lamp body internal surface, the large tracts of land contact leads to the too big problem of frictional force when avoiding surface contact like this, thereby avoid flexible card pause. The bottom end of the outer surface of the upper lamp shell 2 is also provided with a fixing component for fixing the elastic ring 5, and the fixing component is used for fixing the elastic ring 5 at the lower end of the middle lamp shell 3 so as to damage the lamp body due to misoperation during stretching. The upper surface of the lower end of the outer shell of the middle lamp shell 3 is provided with a buckling position 32 for fixing the lower lamp shell 4 connected with the middle lamp shell, the lower lamp shell 4 is fixed at the lower end of the middle lamp shell 3 through the buckling positions through the four buckling positions arranged on the upper surface of the lower end of the middle lamp shell 3, and the light is diffusely reflected on the inner surface of the lower lamp shell 4 to increase the illumination intensity.

The utility model discloses at the during operation, need link to each other screw cap 1 lamp stand that the user predetermines to tensile length between lamp body 2 and the well lamp body 3 is gone up in the concrete condition adjustment according to service environment, and because the arris of lamp body 2 links to each other with the clearance between two adjacent arris in the well lamp body 3 among the tensile process, makes lamp body 2 can not appear the skew of position because the uneven condition of atress among the tensile process. And set up in the inward necking down of well lamp body 3 upper end and can meet with the fixed subassembly of the lower extreme of upper lamp shell 2 when the flexible lamp is stretched completely among the tensile process to the flexible length of restriction continuation tensile upper lamp body 2 avoids the upper lamp shell 2 that leads to because overstretching to drop. The bottom of going up lamp body 2 is provided with fixed subassembly, is provided with elastic ring 5 in this subassembly, and elastic ring 5 is located fixed subassembly in with the internal surface lug connection of well lamp body 3, because its elastic deformation produces the surface of going up

lamp body

2 and 3 internal surfaces of well lamp body and produces the effort, has realized lamp body 2 relative position for well lamp body 3 in the fixed optional position, finally realizes the illumination effect of fixed position. The snap 32 prevents the middle housing from coming off the upper housing surface. Through the design of arris can avoid when flexible face friction to lead to the card to pause the condition, reduce frictional force and be convenient for flexible.

In some embodiments, the upper end of the middle lamp housing 3 is inwardly contracted along the upper side of the middle lamp housing 3, the housing opening formed by inward contraction can just pass through the upper lamp housing 2, when the retractable lamp is fully extended, the upper end of the bottom end fixing device of the upper lamp housing 2 is connected with the contracted end of the middle lamp housing 3, so that the lamp housing is prevented from being directly drawn out due to overlong extension when the lamp body is retracted, and the damage to the lamp body caused by errors in operation is reduced.

In some embodiments, the outer surface of the elastic ring 5 is connected with the inner wall of the middle lamp housing 3, the elastic ring 5 is elastically deformed by being squeezed, and the upper lamp housing 2 and the middle lamp housing 3 are fixed by the action force on the outer housing of the upper lamp housing 2 and the inner housing of the middle lamp housing 3, which is generated by the elastic deformation, so that the structural complexity of the retractable lamp is reduced.

In some embodiments, the inside of the middle lamp housing 3 is provided with six mutually independent edges 31, and since a gap exists between two adjacent edges 31 for placing the edges of the upper lamp housing 2, the six gaps generated by the six mutually independent edges 31 are balanced in stability and economy, and the economic benefit of the retractable lamp is ensured.

In some embodiments, a lamp cap 6 is disposed at the bottom of the lower lamp housing, and the outer diameter of the lamp cap 6 is larger than that of the lower lamp housing. The lamp cap can be used for covering the lamp hole on the suspended ceiling and increasing the illumination area.

Preferably, a lighting assembly is disposed inside the lamp cap. Thus, illumination can be realized at a larger lamp cap, and the illumination area is increased. The lighting assembly may be a variety of light emitting devices that emit light by the electricity of a screw cap. Preferably, the lighting assembly is an LED lamp, which is more energy efficient. In a preferred embodiment, the lamp cap is cylindrical and can be adapted to different lamp hole shapes.
