Next, describe this mechanical adjustable Down lamp in detail by some specific embodiments, as Figure 1-4:
Embodiment 1
Mechanical adjustable Down lamp, it comprises LED lamp holder 1, this lamp holder can adopt the various LED lamp holder in this area, and the structure of LED lamp holder 1 is in the present embodiment: the vertex of a cone that back taper reflector is buckled in light cover, light source is placed in reflector, lamp housing cover on light source and reflector is outside; The adjustment of this LED lamp holder 1 irradiating angle is relevant with each assembly below:
First face shield, its top is the first circular groove 5, bottom is the first disk, first circular groove 5 and the first disk are coaxial and be fixedly connected with, being equivalent to the first face shield is in the present embodiment axially symmetric structure, LED lamp holder 1 is in the first circular groove 5, and can connect by relative radial rotating with the housing of this first face shield, namely, first face shield provides a placement space for LED lamp holder 1, and circular motion can be carried out with LED lamp holder 1, but radial motion is not done with LED lamp holder 1, in order to realize this motion mode, pin is adopted to connect between LED lamp holder 1 and the first face shield, such as bearing pin passes the first face shield two through holes relative with LED lamp holder 1 housing.
The edge of the first circular groove extends upward two braces, 6, two braces 6 and crosses same diameter, and the axle of turbine is fixedly connected with LED lamp holder through one of them brace, and another brace is connected with LED lamp holder pin.
It should be noted that, first circular groove 5 and the first disk can be structure as a whole in other examples, this the first circular groove 5 main purpose is to hold LED lamp holder 1, so, if the shape of the light cover of LED lamp holder 1 changes, such as square, rhombus, so can there is respective change in the first circular groove 5 thereupon.In addition, the first face shield also can not adopt axially symmetric structure in other embodiments, and completely can need to be designed to corresponding shape according to attractive in appearance or other design, as long as meet the most basic function needs, other any change is all fine.
Second face shield, its top is the second circular groove 3, and to be the second chassis 4, second circular groove 3 coaxial with the second chassis 4 in bottom and be fixedly connected with, and the bottom surface inward flange along the second circular groove 3 is provided with circular rail groove.In actual installation, the second chassis 4 can be fixed with stationary plane and be connected, and the second face shield, in Down lamp irradiating angle regulates, any shift in position does not occur.First disk of the first face shield snaps in circular rail groove, and by this connected mode, the first face shield and the second face shield carry out relatively turnable connected mode, and the first face shield can move in a circle in circular rail groove.
First screw 11, its driving force moved in a circle for sending driving LED lamp holder 1, concrete operations are, operator can turn the first screw 11 by instruments such as screwdrivers; First screw 11 is through the bottom surface of the second face shield, it is coaxial that its screw portion penetrates both the first worm screw 2, first screw 11 and the first worm screw 2, and be threaded, first worm screw 2 through the bottom surface of the first face shield, and is welded with the bottom surface of the first face shield (single screw or clamping are replaced); First worm screw 2 is provided with vertical tooth bar, and this vertical tooth bar engages with the vertical tooth bar be arranged on the second circular groove 3 inner surface.
Namely the circular motion of LED lamp holder 1 can be carried out by said structure, be specially: screwdriver rotates the first screw 11, first screw 11 drives the first worm screw 2 to rotate, vertical tooth bar motion on the rack drives second circular groove inner surface of the first worm screw 2, but, second face shield does not move in whole adjustment process, therefore, the vertical tooth bar of the second circular groove inner surface can produce reaction force to the first scroll bar tooth bar, first worm screw 2 drives the first face shield to move in a circle along circular rail groove, first face shield drives LED lamp holder 1 to be synchronized with the movement, and then the LED lamp holder irradiating angle in regulating circumferential direction.
Second screw 10, it is for sending the driving force of driving LED lamp holder 1 radial motion, and operator by the tool into rotation such as screwdriver second screw 10, can produce driving force.Second screw 10 is through the bottom surface of the second face shield, its screw portion penetrates the second worm screw 8, both second screw 10 and the second worm screw 8 are coaxial, and be threaded (available solder or clamping or other fixed forms are replaced in other embodiments), second worm screw 8, through the bottom surface of the first face shield, can not drive the first face shield to rotate when it rotates; Second worm screw 8 is provided with horizontal tooth bar, be meshed with turbine 7, the axle of turbine 7 passes the housing of the first face shield, then be threaded with LED lamp holder 1 (available solder or clamping or other fixed forms are replaced), when the axle of turbine 7 rotates, the first face shield does not move, and turbine 7 Direct driver LED lamp holder 1 does radial motion.
LED lamp holder 1 radial motion is carried out: screwdriver rotates the second screw 10 by said structure, second screw 10 drives the second worm screw 8 to rotate, second worm screw 8 drives turbine 7 to rotate, and turbine 7 drives LED lamp holder 1 to carry out radial motion, and then regulates radial upper LED lamp holder irradiating angle.
Embodiment 2:
The present embodiment does simple modification based on embodiment 1, consider that the second worm screw 8 easily shakes in driving turbine 7 to move, therefore, support 9 is adopted to fix the second worm screw 8 position of having carried out in radial direction in the present embodiment, be specially, one end of support 9 is fixedly connected with the inner bottom surface of the first face shield, and the other end has through hole, passes for the second scroll bar.After support 9 is fixed, the second worm screw 8 then can not shake through through hole again, improves the stability of adjustment.
It should be noted that, between the first screw 11 and the first worm screw 2, adopt fixing connected mode, therefore, the mode of welding or clamping can be adopted in other embodiments.In addition, the first worm screw 2 and the first face shield are synchronized with the movement, and are fixedly connected with so adopt between the first worm screw 2 and the first face shield, in other embodiments, the two can adopt be threaded clamping or other can realize the connected mode of its function.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
