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 holders in this area, and the structure of LED lamp holder 1 is in the present embodiment: back taper reflector is buckled in the vertex of a cone, the lamp housing that light cover, light source be placed in reflector and covers on light source and reflector outside; The adjusting of this LED lamp holder 1 irradiating angle is relevant with each assembly below:
The first face shield, its top is the first circular groove 5, bottom is the first disk, the 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, , the first face shield provides a placement space for LED lamp holder 1, and can carry out circular motion with LED lamp holder 1, but do not do radial motion with LED lamp holder 1, in order to realize this motion mode, between LED lamp holder 1 and the first face shield, adopt pin to connect, such as bearing pin is through the first face shield two through holes relative with LED lamp holder 1 housing.
The edge of the first circular groove extends upward 6, two braces of 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 socket pin.
It should be noted that, in other embodiment, the first circular groove 5 and the first disk can be structure as a whole, these the first circular groove 5 main purposes are in order to hold LED lamp holder 1, so, if the shape of the light cover of LED lamp holder 1 changes, such as square, rhombus, can there is respective change in the first circular groove 5 so thereupon.In addition, the first face shield also can not adopt axially symmetric structure in other embodiments, can need to be designed to corresponding shape according to attractive in appearance or other design completely, as long as meet the most basic function needs, other any change is all fine.
The second face shield, its top is the second circular groove 3, to be the second chassis 4, the second circular grooves 3 coaxial with the second chassis 4 in bottom and be fixedly connected with, and is provided with circular rail groove along the bottom surface inward flange of the second circular groove 3.In actual installation, the second chassis 4 can be fixed and be connected with stationary plane, and the second face shield, in Down lamp irradiating angle regulates, any shift in position does not occur.The 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.
The first screw 11, the driving force that it moves in a circle for sending driving LED lamp holder 1, concrete operations are that operator can turn the first screw 11 by instruments such as screwdrivers; The first screw 11 is through the bottom surface of the second face shield, its screw portion penetrates the first worm screw 2, the first screws 11 and the first worm screw 2, and the two is coaxial, and is threaded, the first worm screw 2 passes the bottom surface of the first face shield, and welds (available screw thread or clamping are replaced) with the bottom surface of the first face shield; The first worm screw 2 is provided with vertical tooth bar, and this vertical tooth bar engages with the vertical tooth bar being arranged on the second circular groove 3 inner surfaces.
Can carry out the circular motion of LED lamp holder 1 by said structure, be specially: screwdriver rotates the first screw 11, the first screw 11 drives the first worm screw 2 to rotate, vertical tooth bar motion on rack drives the second circular groove inner surface of the first worm screw 2, but, the 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, the first worm screw 2 drives the first face shield to move in a circle along circular rail groove, the first face shield drives LED lamp holder 1 to be synchronized with the movement, and then the LED lamp holder irradiating angle of regulating circumferential direction.
The second screw 10, it is for sending the driving force of driving LED lamp holder 1 radial motion, and operator can rotate the second screw 10 by instruments such as screwdrivers, produces driving force.The second screw 10 is through the bottom surface of the second face shield, its screw portion penetrates the second worm screw 8, the two is coaxial for the second screw 10 and the second worm screw 8, and (can use in other embodiments welding or clamping or other fixed forms to replace) is threaded, the second worm screw 8 is through the bottom surface of the first face shield, and it can not drive the first face shield to rotate while rotation; The second worm screw 8 is provided with horizontal tooth bar, be meshed with turbine 7, the axle of turbine 7 is through the housing of the first face shield, then (available welding or clamping or other fixed forms are replaced) is threaded with LED lamp holder 1, when the axle of turbine 7 rotates, the first face shield does not move, and the direct driving LED lamp holder 1 of turbine 7 does radial motion.
Carry out 1 radial motion of LED lamp holder by said structure: screwdriver rotates the second screw 10, the second screw 10 drives the second worm screw 8 to rotate, the second worm screw 8 drives turbine 7 to rotate, the motion that turbine 7 drives LED lamp holder 1 to carry out radially, and then regulate upwards LED lamp holder irradiating angle of footpath.
Embodiment 2:
The present embodiment does simple modification based on embodiment 1, considering that the second worm screw 8 drives in turbine 7 motion easily shakes, therefore, adopting in the present embodiment support 9 to carry out position upwards, footpath to the second worm screw 8 fixes, 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 can not shake through through hole again, has improved the stability regulating.
It should be noted that, between the first screw 11 and the first worm screw 2, adopt fixing connected mode, therefore, can adopt in other embodiments the mode of welding or clamping.In addition, the first worm screw 2 and the first face shield are synchronized with the movement, so adopt and be fixedly connected with between the first worm screw 2 and the first face shield, in other embodiments, the two can adopt and be threaded or clamping or other can be realized the connected mode of its function.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
