The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described, shown in Fig. 1~8, a kind of street lamp that the utility model provides includes loam cake 1, lower cover 2, light supply apparatus 3, ballast 4, loam cake 1 fastens mutually with lower cover 2, light supply apparatus 3 and ballast 4 are installed between loam cake 1 and the lower cover 2, wherein, light supply apparatus 3 comprises parts such as fluorescent tube, reflection shield, lamp holder, transparent glass lid, waterproof grommet; The utility model comprises also and is used for fixing the tailstock 5 that connects lamp stand that the afterbody of lower cover 2 offers the disposal area 21 that is used for mounted tailstock 5, makes lower cover 2 can pass through tailstock 5 fixedly connected lamp stands, and then fixing whole street lamp; The top of disposal area 21 is provided with the adjusting tooth bar 22 that is used to regulate lower cover 2 fixed angles, and the top of tailstock 5 is provided with and regulates the first tailstock tooth bar 51 of tooth bar 22 engagements.Because the elevation angle of each tooth of adjusting tooth bar 22 is all inequality, for example: the elevation angle of previous tooth is than little 5 degree in the elevation angle of a back tooth, so, as long as regulate the first tailstock tooth bar 51 and the angle of regulating tooth bar 22 engagements, just can regulate the fixed angle of lower cover 2, promptly regulate the elevation angle of whole street lamp, thereby adjust the polishing scope of street lamp.
The utility model further comprises pressing plate 6, the fixed screw 7 of the tailstock 5 that is used to be locked, pressing plate 6 offers the pressing plate screw 61 with fixed screw 7 couplings, regulate tooth bar 22 and offer the through hole 23 that passes for fixed screw 7, the first tailstock tooth bar 51 of tailstock 5 offers the first tailstock screw 52 with fixed screw 7 couplings, so, fixed screw 7 passes pressing plate screw 61, through hole 23, the first tailstock screw 52 successively, just tailstock 5 can be locked in disposal area 21.
The top that present embodiment is regulated tooth bar 22 forms adjusted tooth 24, the bottom of regulating tooth bar 22 forms down regulating tooth 25, the bottom of pressing plate 6 is provided with the pressing plate tooth bar 62 with 24 engagements of adjusted tooth, the first tailstock tooth bar 51 on tailstock 5 tops and following regulating tooth 25 engagements; Wherein, regulating tooth bar 22 is arc rack, the first tailstock tooth bar 51 is two gear racks, pressing plate tooth bar 62 is three gear racks, the tooth top of the tooth top of adjusted tooth 24 and following regulating tooth 25 is from front to back and uprises gradually, the elevation angle that is previous tooth is littler than the elevation angle of a back tooth, and wherein, the tooth of close lower cover 2 tail ends is the rear end; The structure at this adjusting elevation angle not only can be regulated the elevation angle easily, and intermeshing fixed structure, connects very firm.
The tailstock 5 of present embodiment offers the installing hole 53 that is used to install lamp stand, makes street lamp can be fixed on the lamp stand; The front end of tailstock 5 is provided with the second tailstock tooth bar 54, the second tailstock screw 55, so that be fixed tailstock 5 in the horizontal direction by screw; The both sides of tailstock 5 are provided with clamping axle 56, are provided with in the disposal area 21 and clamping axle 56 corresponding groove positions, so that the rotation of tailstock 5 when regulating the elevation angle.
Be fixed with the dividing plate 8 that is used to isolate light supply apparatus 3 and ballast 4 between the loam cake 1 of present embodiment and the lower cover 2, promptly light supply apparatus 3 and ballast 4 are isolated by dividing plate 8, adopt this structure, the heat transferred ballast 4 that produces in the time of can avoiding or reduce light supply apparatus 3 work, guarantee the operate as normal of ballast 4, prolong the service life of ballast 4.
The top surface of present embodiment ballast 4 is the plane, and the inboard of loam cake 1 forms the mounting plane 11 that the top surface with ballast 4 fits tightly; Be coated with one deck heat-conducting silicone grease on the mounting plane 11, fit tightly by heat-conducting silicone grease between the top surface of ballast 4 and the mounting plane 11, be equivalent to ballast 4 and form integrative-structure with loam cake 1, utilize loam cake 1 directly to derive the heat of ballast 4, thereby reach the purpose of heat radiation, to guarantee the operate as normal of ballast 4, prolong the service life of ballast 4; Simultaneously, the outer surface of loam cake 1 and mounting plane 11 corresponding positions form fin 12, and fin 12 is a plurality of, and this kind structure can further be accelerated the radiating rate of ballast 4.
In the time need being adjusted to the different elevations angle to street lamp, at first to back out other retaining element of fixed screw 7 and tailstock 5, because the first tailstock tooth bar 51 is two gear racks, and have only a teeth groove, so, as long as the first tailstock tooth bar 51 of the tailstock 5 that will unclamp is from the tooth of original and following regulating tooth 25 engagements, snap fit onto down in the another one tooth of regulating tooth 25, just can the regulating tooth position, certainly, the elevation angle of this tooth is exactly the elevation angle that the street lamp shell need be adjusted to; Then, with the pressing plate tooth bar 62 and the 24 coupling engagements of adjusted tooth of pressing plate 6, and other retaining element of screw on again fixed screw 7 and tailstock 5, can be adjusted to the another one elevation angle to the street lamp shell, thereby adjust the polishing scope of street lamp.
Should be noted that at last; above embodiment is only in order to the explanation the technical solution of the utility model; but not to the restriction of the utility model protection domain; although the utility model has been done to explain with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the essence and the scope of technical solutions of the utility model.
