Description

Liftable LED street lamp

Technical Field

The utility model belongs to the street lamp field, concretely relates to liftable LED street lamp.

Background

The LED street lamps on roads, streets and public squares are widely applied, have important functions on urban traffic, public security and beautification, and are turned on at night and turned off at dawn.

The lamp holder of LED street lamp all fixes on the support arm, and the support arm is fixed on the lamp pole, and the unable lift adjustment of lamp holder is unfavorable for maintainer to change the maintenance to the lamp holder, and simultaneously, LED street lamp can't be when the installation according to required height-adjusting, lacks the nature of going up and down, has the restriction of height to the region of difference, and the LED street lamp that does not have raising and lowering functions just can't be applicable to various occasions and installs, and the limitation is great.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model provides a liftable LED street lamp.

The utility model discloses a realize through following technical scheme: the utility model provides a liftable LED street lamp, includes the stand, the vertical rigid coupling in stand top has the slide bar, the fixed supporting seat that is equipped with in stand upper end, the threaded rod is installed in the vertical rotation of both sides difference of supporting seat, and the middle part is provided with the motor, the threaded rod with the slide bar sets up for the mutual symmetry of axis, two driven gear has been cup jointed respectively to the lower extreme of threaded rod, the cover is equipped with the driving gear on the output shaft of motor, driving gear and two driven gear meshes, the xarm that the illumination lamp body was installed to one end is established to the upper end cover of slide bar is located the slide bar both sides be equipped with the nut cover in the xarm respectively, in the xarm nut cover is established correspondingly on the threaded rod.

And a limiting cap is arranged at the top end of the sliding rod.

The top of threaded rod is equipped with the stopper.

The motor is an asynchronous motor.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses set up threaded rod and slide bar, the motor drives the driving gear rotatory, and the driving gear drives driven gear rotatory, and then makes the threaded rod rotatory make the xarm reciprocate take the adjustment of LED lamp holder oscilaltion, does benefit to maintainer and changes the maintenance to the lamp holder, and it is less to have the restriction of height in the region of difference, is applicable to various occasion installations, and the limitation is less.

Detailed Description

The liftable LED street lamp shown in figures 1 to 3 in the attached drawings of the specification comprises a stand column 1, a slide rod 2 is vertically and fixedly connected to the top end of the stand column 1, a supporting seat 3 is fixedly arranged at the upper end of the stand column 1, threaded rods 4 are vertically and rotatably arranged on two sides of the supporting seat 3 respectively, a motor 5 is arranged in the middle of the supporting seat, the threaded rods 4 are symmetrically arranged with the slide rod 2 as an axis, driven gears 6 are sleeved at the lower ends of the two threaded rods 4 respectively, a driving gear 7 is sleeved on an output shaft of the motor 5, the driving gear 7 is meshed with the two driven gears 6, a cross arm 8 with a lighting lamp body mounted at one end is sleeved at the upper end of the slide rod 2, nut sleeves 12 are arranged in the cross arms 8 on two sides of the slide rod 2 respectively, the nut sleeves.

The top end of the sliding rod 2 is provided with a limit cap 10.

The top end of the threaded rod 4 is provided with a limiting block 11.

The motor 5 is an asynchronous motor, can realize instant starting and rapid stopping, and changes the rotation direction of the motor by changing pulse signals.

Controller 9 electric connection motor 5, controller 9 control motor 5 start-up rotation, and motor 5 drives the driving gear 7 rotatory, and then drives two driven gear 6 rotations, and then drives threaded rod 4 rotatory to make xarm 8 reciprocate and take the adjustment of LED lamp holder oscilaltion.

In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications of the shapes, structures, features and spirit described in the claims of the present invention should be included in the scope of the present invention.
