Abstract
The present invention relates to a kind of lamp cap adjustable desk lamps, the present invention allows two lamp caps to rotate freely in horizontal circumference by the way that two lamp caps are arranged on lamp stand, rotates two lamp caps to lamp stand and stops side position, in horizontal circumference two lamp caps are the largest illumination range at 180 degree.It is minimum illumination range when rotating two lamp caps to overlapping positions.User can according to need freely to be adjusted in maximum and minimum illumination range section.The present invention solves user's difference using demand of the scene to light, brings advantage to the user.
Description
Technical field
The present invention relates to photoelectric lighting field more particularly to a kind of lamp cap adjustable desk lamps.
Background technique
At present at home, in office lighting use process, the different required light areas of usage scenario are different, lamp
The range of size how much illumination of head is also different.Study and work eyes can just relax under illumination is big and uniform light environment
It is suitable.Desk lamp holder on the market has plenty of fixed, and what is had can only adjust illumination range by longitudinal.It is i.e. enabled to be adjusted to need
The illumination requirement wanted, and people is needed to deacclimatize and cooperate the position of lamp, cause using inconvenience.
Summary of the invention
The present invention is to overcome above-mentioned shortcoming, and it is an object of the present invention to provide a kind of lamp cap adjustable desk lamp, the present invention are logical
Lamp cap there are two setting on lamp stand is crossed, and lamp cap is freely adjustable, when needing larger light environment, rotary lamp holder to lamp stand
Only side position, can reach maximum illumination range, and rotary lamp holder can reach minimum illumination range to when being overlapped.Maximum illumination range
And it can freely be adjusted according to demand between minimum illumination range.
The present invention is to reach above-mentioned purpose by the following technical programs: a kind of lamp cap adjustable desk lamp, comprising: lamp stand bottom
Seat, lamp stand upper cover, lamp cap, nut；There are two the lamp caps, and there are two the nuts；On lamp stand pan frontward end horizontal line
If the shaft that two lamp caps itself have penetrates through the rotary shaft through hole of lamp stand pedestal, and passes through two spiral shells there are two rotary shaft through hole
Mother is tightened, and realizes the connection of two lamp caps and lamp stand pedestal；Lamp stand pedestal and lamp stand upper cover are connected with each other.
Preferably, the lamp cap includes lamp holder base, lamp cap upper cover, shaft, T-type gasket；Lid is equipped on lamp cap
Rotary shaft through hole, shaft penetrate through the through-hole on lamp cap on lid, and lamp cap upper cover is connected with lamp holder base, fix shaft, T-type gasket
The convex edge insertion having is connected in the rotary shaft through hole of lamp cap upper cover.
Preferably, step is equipped on the inside of the junction of the lamp stand pedestal and lamp cap, for limiting two lamp caps
Stroke guarantees maximum gauge and maximum light area of two lamp caps in horizontal circumference.
Preferably, described shaft one is equipped with flange, one is equipped with external screw thread.
Preferably, the flange is in long kidney ellipsoid.
Preferably, the lamp cap upper cover is equipped with the through-hole passed through for shaft, wherein the both sides of through-hole are equipped with and turn
Two chimbs that the flange of axis matches, prevent shaft rotation by the mutual cooperation of flange and chimb.
The beneficial effects of the present invention are: the present invention can be adjusted arbitrarily by two lamp caps of setting, increase lamps and lanterns
Light area while can freely adjust suitable illumination range according to actual needs, allow lamp go cooperation human needs, no
It increases only the convenience used and gives comfortable study and work environment.

Specific embodiment
The present invention is described further combined with specific embodiments below, but protection scope of the present invention is not limited in
This:
Embodiment: as shown in Figure 1, Figure 2, Figure 3 shows, a kind of lamp cap adjustable desk lamp is by lamp stand pedestal 1, lamp stand upper cover 2, lamp
First 3, nut 4 forms.Wherein lamp cap 3 includes 2 lamp caps, and nut 4 has 2.
Lamp cap 3 includes lamp holder base 3-1, lamp cap upper cover 3-2, shaft 3-3, T-type gasket 3-4.Lamp cap upper cover 3-2 is equipped with
Rotary shaft through hole, through-hole both sides are equipped with chimb, and shaft 3-3 mono- is equipped with long kidney ellipsoid flange, and one is equipped with external screw thread.Shaft 3-3
Through-hole on lamp cap upper cover 3-2, lamp cap upper cover 3-2 are connected with lamp holder base 3-1 again, fix shaft 3-3, shaft 3-3
Long oval flange and lamp cap upper cover 3-2 shaft both sides chimb cooperation, prevent shaft rotation.The convex edge of T-type gasket 3-4 is embedding
In the shaft hole for entering to be installed to lamp cap upper cover 3-2, to form lamp cap 3 together.
It is set on 1 front end horizontal line of lamp stand pedestal there are two rotary shaft through hole, the shaft of two lamp caps 3 passes through lamp stand pedestal 1
Rotary shaft through hole screws on two nuts 4 respectively, realizes the connection of two lamp caps 3 and pedestal 1, and lamp stand pedestal 1 and lamp stand upper cover 2 connect
It connects.It is equipped with step on the inside of the junction of lamp stand pedestal 1 and lamp cap 3, limits the stroke of two lamp caps 3, guarantees two lamp caps 3 in circle
Horizontal maximum gauge and maximum light area in week.
As shown in Figure 4, Figure 5, as needed when use, two lamp caps go to lamp stand pedestal and stop side as maximum light area, and two
Lamp cap goes to coincidence as minimum light area, can freely adjust in minimum and maximum light area.
It is specific embodiments of the present invention and the technical principle used described in above, if conception under this invention institute
The change of work when the spirit that generated function is still covered without departing from specification and attached drawing, should belong to of the invention
Protection scope.
