Abstract
The utility model discloses an upper-lower illumination-angle regulating mechanism for a lamp, characterized in that the utility model is composed of an arc rack which can be mounted on the tail of the lamp assembly casing and a long handle worm screw engaged with the arc rack. The arc rack of the upper-lower illumination-angle regulating mechanism for a lamp can be mounted on the tail of the lamp assembly casing, and the long handle worm screw can be mounted on the site of a bracket which can be engaged with the arc rack; the projected handle of the long handle worm screw is convenient for people to screw the worm screw to rotate. For use, operators only need to screw the worm screw to rotate; since the long handle worm screw is engaged with the arc rack mounted on the tail of the lamp assembly casing, the lamp assembly can rotate around a rotation shaft on the bracket through screwing the worm screw, to arbitrarily regulate the upper-lower illumination-angle of the lamp assembly. The utility model overcomes the defect existing in the prior art of inconvenient and inaccurate upper-lower illumination-angle regulation of the lamp, suitable for various structures of lamps.
Description
Technical field
The utility model relates to lamp fittings, especially a kind of light fixture illumination is angle adjusting mechanism up and down.
Technical background
At present, various billboards, buildings and large-scale sculpture etc. have all set illuminating lamp in the city, this class is made up of support of being convenient to install and fix on object and hinged thereon illuminating lamp assembly usually, the illuminating lamp assembly that is hinged on the support can rotate around jointed shaft, and the lighting angle up and down of illuminating lamp can be regulated by linkwork.Yet in actual use, it is found that light fixture unlatching back heat can make the lamp casing temperature raise fast.Therefore, directly touch light fixture and regulate its light angle, very difficulty with hand.Can burn operator's hand of the lamp outer casing of temperature overheating.
Summary of the invention
The purpose of this utility model is the deficiency that exists at above-mentioned light fixture, and a kind of easy to operate, angular adjustment light fixture illumination accurately angle adjusting mechanism up and down is provided.
The illumination of the utility model light fixture is angle adjusting mechanism up and down, it is characterized in that: can be made up of with the long handle worm screw of arc-shaped rack engagement an arc-shaped rack and that can be installed in the housing afterbody of lamp assembly.
Described arc-shaped rack is an arc-shaped rack.
The utility model light fixture illumination design principle of angle adjusting mechanism up and down is: utilize the engaged transmission of worm screw and arc-shaped rack, impel lamp assembly to rotate around the axis on support.
The illumination of the utility model light fixture is angle adjusting mechanism design science up and down, and is simple in structure, uses easy to operate, flexible.The light fixture illumination up and down arc-shaped rack of angle adjusting mechanism can be fixedly mounted on the housing afterbody of lamp assembly, the long handle worm screw by axle sleeve be installed in can with the support portions of arc-shaped rack engagement, the handle of the long handle worm screw that stretches out conveniently turns worm screw for people and rotates.During use, operator's only with hand turns the long handle worm screw and rotates, rely on long handle worm screw and the arc-shaped rack engagement that is installed in the lamp casing afterbody, can impel lamp assembly on support, to rotate around the axis, any adjusting of lower angle in the illumination of realization lamp assembly by turning the long handle worm screw.Overcome and existed in up and down angular adjustment inconvenience of light fixture illumination in the prior art, and inaccurate defective, the utility model design is applicable to various structure light fixtures.
The utility model light fixture illumination concrete structure of angle adjusting mechanism is up and down provided in detail by the following drawings and embodiment.
Description of drawings
Fig. 1 is the light fixture illumination structural representation of angle adjusting mechanism up and down;
Fig. 2 is light fixture illumination shown in Figure 1 angle adjusting mechanism mounting structure schematic diagram on light fixture up and down.
The specific embodiment
Embodiment: from Fig. 1 can be clear that light fixture illumination up and down angle adjusting mechanism form by arc-shaped rack 1 and long handle worm screw 2, described arc-shaped rack 1 both sides are provided with as its deck of installing on light fixture 11, and deck 11 is provided with the open slot 12 that places for screw; Described long handle worm screw 2 is by constituting with arc-shaped rack engaged worm 21 and the handle 22 that is connected worm screw 21 1 ends, and an end of handle 22 is a flat.
Fig. 2 is the structural representation that angle adjusting mechanism is installed on light fixture about the light fixture illumination, from illustrating as seen, this is a kind of light fixture of being made up of lamp assembly 3 and support 4, lamp assembly 3 is installed on the support 4 by rotating shaft 5, lamp assembly 3 can 5 rotate on support 4 around the shaft, the arc-shaped rack 1 of angle adjusting mechanism is fixedly mounted on the afterbody of shell 31 outside the lamp assembly 3 about the illumination of this light fixture by screw, long handle worm screw 2 is installed in the axis hole 41 of support 4 reservations, and the handle 22 that is arranged on worm screw 21 ends is derived the manipulation for the people from axis hole 41.
