wheel 4 is connected with a
driving wheel 5 in a meshed manner, the right side of the
driving wheel 5 is fixedly provided with a
wheel shaft 6, the right end of the
wheel shaft 6 sequentially penetrates through the right side surface of the
lamp post 1 and the
fixed block 7 and extends to the outside of the right side of the
fixed block 7, the outer surface of the
wheel shaft 6 is movably sleeved with a fixed
square frame 9 positioned on the right side of the
fixed block 7, a
sliding square groove 12 is formed in the
fixed square frame 9, the right end of the
wheel shaft 6 is fixedly provided with a
sliding square block 10 positioned in the
sliding square groove 12, the
sliding square block 10 can move left and right in the
sliding square groove 12 and cannot rotate, the fixed
square frame 9 is rotated, the fixed
square frame 9 drives the
wheel shaft 6 to rotate so as to rotate the threaded
rod 3, the threaded
rod 3 can be rotated so that the threaded
slider 14 can move up and down on the outer, so that the
fixed frame 9 is always in close contact with the inside of the
limit square groove 8 under the action of non-external force to limit the rotation of the
fixed frame 9, the outer surface of the
wheel shaft 6 is movably sleeved with an
elastic spring 11 positioned inside the
sliding square groove 12 and on the left side of the
sliding square block 10, the left end and the right end of the
elastic spring 11 are respectively fixedly connected with the left end of the
sliding square groove 12 and the left end of the
sliding square block 10, the right end of the
fixed frame 9 is fixedly provided with a
rotating shaft 13, the outer surface of the rotating
shaft 13 is fixedly sleeved with a rocker, the bottom of the right side of the rocker is fixedly provided with a handle, the outer surface thread of the threaded
rod 3 is sleeved with a threaded
slider 14 positioned above the
fixed pile 2, the upper end and the lower end of the right side of the threaded
slider 14 are fixedly provided with
lamp holders 15, the right side of the
lamp holder 1 is provided, the right-hand member fixed mounting of
lighting fixture 15 has
lamp stand 16, the top fixed mounting of
lamp stand 16 has the heat dissipation muscle, the bottom fixed mounting of
lamp stand 16 has
lamp shade 22, the equal fixed mounting in both ends has
dead lever 17 about
lamp stand 16 top, the top fixed mounting of two
dead levers 17 has
filter screen 19,
filter screen 19 central authorities highly be greater than the height at both ends, filter notch has been seted up to filter
screen 19's inside, the outer fixed surface of two
dead levers 17 has cup jointed water-
collecting plate 18, the fixed intercommunication in middle part of water-collecting
plate 18 has
aqueduct 20, the inside fixed mounting of
lamp stand 16 has water-
cooling tube 21, the water inlet of water-
cooling tube 21 and the fixed.
When the LED garden street lamp is used, the fixing
square frame 9 is pulled rightwards to enable the fixing
square frame 9 to be separated from the limiting effect of the limiting
square groove 8, then the
fixing square frame 9 is rotated, the
wheel shaft 6 is driven by the fixing
square frame 9 to rotate, so that the threaded
rod 3 is rotated, the threaded
slide block 14 cannot rotate under the limiting effect of the
lamp holder 15 and the sliding rod groove due to the fact that the
lamp holder 15 penetrates through the sliding rod groove, therefore, the threaded
rod 3 can be rotated to enable the threaded
slide block 14 to move up and down on the outer surface of the threaded
rod 3, the
lamp holder 15 is lowered to a proper position by rotating the fixing
square frame 9, then the LED garden street lamp is replaced or maintained, then the
lamp holder 15 is lifted to the top of the
lamp pole 1 by rotating the fixing
square frame 9 again, the fixing
square frame 9 is placed inside the limiting
square groove 8 to fixedly limit the rotation of the fixing
square frame 9, the, avoid the inside high temperature of this LED garden street lamp, in the midsummer period, the staff can drop
lighting fixture 15 and pour into appropriate amount of water into to the inside
water catch sheet 18 and further improve this LED garden street lamp's heat dissipation function.
