Detailed description of the invention
In order to allow those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figures 1 to 4, a kind of desk lamp, comprises base 1, support member 2, lampshade 3 and bulb 4.The lower end of support bar is connected with base and is positioned at the center of base.The lower end of support member 2 is arranged on base 1, and is positioned at the center position of disciple, makes base uniform force.This support member 2 comprises the cylindrical support frame 21, telescopic support bar 22 and the fixture 23 for fixing between bracing frame 21 and support bar 22 that are vertically fixed on base 1 upper surface.Described bracing frame 21 is smooth cylindrical metal tube.Described support bar is the smooth metal tube of the more piece that can stretch in support bar, when stretching out, is pulled out by more piece metal tube, extends the length of support bar, during shortening, pushed inside metal tube by more piece metal tube.The vertical core 231 for fixing fixture 23 and the cross-drilled hole 232 for fixed support bar 22 is provided with in described fixture 23; Vertical core 231 and cross-drilled hole 232 are positioned at fixture, and in 90 degree between vertical core 231 and cross-drilled hole 232.The outside of described vertical core 231 is provided with one for the hold-down nut up and down 233 of the part that is locked.The vertical core 231 of fixture penetrates in bracing frame 21, and fixture 23 is by the vertical core 231 in fixture and the hold-down nut up and down 233 synergy fixing support rack 21 that is arranged on outside vertical core.The outside of described cross-drilled hole 232 is provided with one for the hold-down nut 234 of the support bar 22 that is locked.Support bar 22 penetrates in the cross-drilled hole 232 of fixture, and support bar 22 is by the cross-drilled hole 232 in fixture and the hold-down nut 234 synergy fixed support bar 22 that is arranged on outside cross-drilled hole 232.During adjustment support bar 22 height, the upper and lower hold-down nut 233 of manual rotation, moves to required height by fixture 23, then tightens upper and lower hold-down nut 233, fixture 23 is fixed on required height.Because bracing frame 21 is vertical with support bar 22, and support bar 22 stretches out, and can prevent fixture 23 landing, and support bar can also rotate in workbench with axle centered by the vertical core 231 of fixture simultaneously, and the anglec of rotation is 180.
Preventing fixture from landing bracing frame to better fix fixture 33, improving stability, the surface of bracing frame 21 is evenly provided with aduncate circular groove 211.Time fixing, upper and lower hold-down nut 233 be screwed in circular groove 211, effectively can prevent fixture 23 landing.
Lampshade 3 is fixed on the end of support bar, and bulb 4 is arranged in lampshade 3.
State embodiment and be only wherein specific implementation of the present utility model, it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these apparent replacement forms all belong to protection domain of the present utility model.
