Abstract
The invention provides a lamp with the adjustable illuminating direction. The lamp comprises a lamp holder and a lamp socket. The lamp socket is provided with a rotating adjustment block capable of rotating along with rotation of the lamp holder. The lamp holder, the lamp socket and the rotating adjustment block are connected in a rotating mode through a fastening piece. The rotating adjustment block comprises an arc-shaped part connected with the lamp socket in a rotating mode. A protrusion is arranged on the arc-shaped part. The lamp socket is provided with an arc-shaped groove matched with the arc-shaped part. A plurality of limiting strips which are sequentially arranged in parallel and at a certain distance intervals are arranged in the arc-shaped groove. Gaps for the protrusion to be clamped into are formed among the limiting strips. By means of the fact that the rotating adjustment block rotates relative to the lamp socket, the purpose of fast adjusting the illuminating direction of the lamp holder can be achieved, and therefore illuminating requirements of on-sites and emergencies are met. When the protrusion on the rotating adjustment block rotates into the gap between the two limiting strips, resistance effect of the limiting strips on the protrusion enables the rotating adjustment block to stop, and an angle of the illuminating direction of the lamp holder at the moment maintains constant. The illuminating direction of the lamp holder is convenient to adjust and high in adjustment precision.

The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
As shown in Figure 1, 2, 3, a kind of light fixture of regulating direction of illumination that the embodiment of the present invention provides, comprise lamp holder 1 and lamp socket 2, described lamp holder 1 is provided with one can be with the rotation regulating block 3 of lamp holder 1 rotation, be rotationally connected by a securing member 4 between lamp holder 1, lamp socket 2 and rotation regulating block 3, securing member 4 is the connectors commonly used such as rivet or pin.When light fixture uses, lamp socket 2 can be fixed on working equipment or the helmet of carrying, belt.When needs are regulated the direction of illumination of lamp holder 1, only need with hand rotary lamp holder 1, lamp holder 1 can rotate with respect to lamp socket 2 by rotating regulating block 3, thereby realizes the purpose of the direction of illumination of quick adjustment lamp holder 1, to satisfy the lighting requirement of scene or emergency case.
As one embodiment of the invention, described rotation regulating block 3 can be one-body molded with lamp holder 1, makes rotation regulating block 3 to rotate with lamp holder 1.
As another embodiment of the present invention, described rotation regulating block 3 and lamp holder 1 also can be made respectively, be specially: as shown in Fig. 4,5, described rotation regulating block 3 comprises a horizontal part 31 and a curved portions 32, horizontal part 31 is fitted with the bottom surface 11 of lamp holder 1, rotating regulating block 3 when making lamp holder 1 rotate can rotate together along with lamp holder 1, and the upper end of curved portions 32 or lower end position are provided with a projection 321, and projection 321 is taper, semicircle is spherical, cylindrical or the shape such as square column type.Offer an arc groove 21 that coordinates with curved portions 32 on described lamp socket 2, be provided with some positive stop strips that are arranged in parallel successively and keep at a certain distance away 22 in arc groove 21, these some positive stop strips 22 are combined into laciniation, wavy structure or step structure, form between this each positive stop strip 22 to hold protruding 321 gaps that snap in 23.
As shown in Fig. 3,4,5, the bottom surface 11 of described lamp holder 1 convexes with two the first parallel and keep at a certain distance away gussets 12, offer respectively one first connecting hole 121 on two first gussets 12, the upper surface 24 of described lamp socket 2 convexes with two the second parallel and keep at a certain distance away gussets 25, offer respectively one second connecting hole 251 on two second gussets 25, offer one the 3rd connecting hole 33 on described rotation regulating block 3.During installation, securing member 4 is arranged in two first connecting holes 121, two second connecting holes 251 and the 3rd connecting hole 33, thereby realizes lamp holder 1, lamp socket 2 and rotate being rotationally connected between regulating block 3.
See also Fig. 1 ~ shown in Figure 5, the assembling process of regulating the light fixture of direction of illumination of the present invention is: at first, between two the first gussets 12 that rotate regulating block 3 and be placed on the bottom surface 11 of lamp holder 1, the first connecting hole 121 of two the first gussets 12 on the bottom surface 11 of the 3rd connecting hole 33 that rotates on regulating block 3 and lamp holder 1 is alignd; Then, two the first gussets 12 on lamp holder 1 bottom surface 11 are inserted between two the second gussets 25 on the upper surface 24 of lamp sockets 2, the second connecting hole 251 on the first connecting hole 121 on two the first gussets 12, two the second gussets 25 and the 3rd connecting hole 33 that rotates on regulating block 3 are all alignd, at last securing member 4 is inserted in two the first connecting holes 121, two the second connecting holes 251 and the 3rd connecting hole 33, and fixed, thereby lamp holder 1, lamp socket 2 and rotation regulating block 3 are rotatably connected, have completed the assembling of light fixture.
When need are regulated the direction of illumination of lamp holder 1, at first use hand rotary lamp holder 1, owing to fitting in the horizontal part 31 that rotates regulating block 3 and the bottom surface 11 of lamp holder 1, therefore rotate regulating block 3 and can rotate around securing member 4 together along with lamp holder 1; Projection 321 on rotating regulating block 3 turns to gap 23 between two positive stop strips 22 when interior, the staff lamp holder 1 that stops operating, to rotate regulating block 3 slack because the drag effect of 22 pairs of projections 321 of positive stop strip makes, and makes the direction of illumination of lamp holder 1 keep the angle of this moment constant; Then check the direction of illumination of lamp holder 1, if do not meet the demands, be rotated further lamp holder 1 until suitable position.The angle (rotation precision) that lamp holder 1 often turns is once determined by the angle between adjacent two positive stop strips 22, the rotational angle range of lamp holder 1 is determined by the quantity of positive stop strip 22, therefore, rotation precision that can be actual required according to lamp holder 1 and slewing area arrange corner dimension between every adjacent two positive stop strips 22 and the quantity of positive stop strip 22.
As shown in Figure 1, as the present invention's one specific embodiment, every adjacent two positive stop strips 22 are 12 ° with respect to securing member 4 for the angle in the center of circle, positive stop strip 22 always has six, therefore lamp holder is 1 each rotatable 12 °, and lamp holder 1 rotatable scope altogether is 5 * 12 °+9 °=69 ° (wherein, six positive stop strips 22 form the angle of five 12 °, and when 9 ° to be projection 321 contact with the positive stop strip 22 at edge, protruding 321 and the positive stop strip 22 at this edge be the corner dimension in the center of circle with respect to securing member 4).
The above is the preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also are considered as protection scope of the present invention.
