Abstract

The utility model belongs to a lighting class. The road lamp pillar capable of bending is provided for overcoming the problem road lamps at garden green areas and near tortuous paths inconveniently use servicing automobiles with a lifting platform. The utility model is composed of a base, a lamp pillar and a lighting lamp, wherein, a rotatable hinge shaft is arranged the lamp pillar and the base. The bend rotation of the rotatable hinge shaft is controlled by a set of controllable deceleration mechanism which comprises a deceleration worm wheel and deceleration gear. A rocking handle is arranged on an exposed shaft head of the gear, the rocking handle is rocked, and the lamp pillar can be slowly bent and lowered. A worker can take time to operate. After the worker works, the lamp pillar is erected to be in a vertical state, and is locked by bolts through alignment through holes. The utility model has the characteristics of simple structure, convenient operation and novel shape.

Description

But the light pole of bending

The utility model belongs to the lighting apparatus class, and it is specifically related to a kind of structure of light pole that can bending.

Generally on the highway or the road side in city street lamp is housed all, it also has certain cosmetic decoration effect except that the function with illumination, and especially the street lamp of multiple modern design continues to bring out in the greenery patches of park or sheet.Street lamp is wanted frequent maintenance when long-term the use, generally all use the automobile that has elevating stage to carry out work high above the ground.But to be arranged in the greenery patches or path take up street lamp on the greenery patches, flower garden, the automobile of then aforementioned maintenance usefulness just can't be worked, the mode of the maintenance and repair of crawling in the personnel selection directly says it is extremely worthless at present, and the lamp stand of special construction also difficulty swash.

But the purpose of this utility model is to provide a kind of light pole of bending for solving aforesaid problem, lamp stand can be stooped when maintaining, and a very important person just can well work before arriving lamp, and can not damage the greenery patches in roadside and other facility.

By as above design, but the light pole of the bending that this programme provided is made up of pedestal, lamp stand and illuminating lamp, it is characterized in that it lamp stand and pedestal between link with hinge, one through hole that aligns mutually and fastening with a bolt, nut is arranged on lamp stand and the pedestal when lamp stand is vertical state, and the bending action of lamp stand is to be controlled by the controlled reducing gear transmission of a cover.

In this programme, its controlled speed reduction gearing is paid with one-level gear pair deceleration institute by first-stage worm gear and is constituted, its worm gear is contained on the hinge of lamp stand, be connected into the relation of synchronous rotation between lamp stand, hinge and the worm gear with binding, worm screw is coaxial and be fixedly connected with gear wheel, and pinion shaft is equipped with dismountable crank on the spindle nose that pedestal exposes.The hinge of worm gear, worm shaft and pinion shaft all support and are installed on the inwall of pedestal with bearing support in this lamp stand.

Adopt this programme can embody following superiority: but 1. the light pole of this bending is particularly suitable for being contained among the meadow or the maintenance of tortuous path bypass lamp, it is the bad occasion that enters work of automobile of maintaining, all need good-looking street lamp to go to decorate as the greenery patches in a lot of greenery patchess of development and the flower garden in the present city, all there is problem difficult in maintenance, but there has been this problem of light pole of bending then to be readily solved: at first to pull down set bolt when 2. working, load onto crank, when shaking it, then lamp stand bending rotation lentamente under the effect of worm and gear of lamp stand, when partly reducing, just can operate easily by illuminating lamp: the operating condition of 3. having improved the workman, avoided the climbing danger of bar, also saved the discomfort when elevating stage is lifted on the high-altitude, it is good to stand on the ground job security; 4. its simple in structure, modern design, function superior, be convenient to operation, be that beautifying of modern city created good condition.

But Fig. 1 is the front view of the light pole of this programme bending, and the outward appearance situation of this street lamp is described.

Fig. 2 is the part enlarged drawing of the lateral view of Fig. 1, and the structure of controlled deceleration transmission part is described.

The embodiment of existing accompanying drawings this programme.But the light pole that is somebody's turn to do bending is made of pedestal 1, lamp stand 2 and illuminating lamp 3, the top that is fixedly mounted on ground pedestal is a square cylindricality, its lamp stand is to be welded into by two flat wide long tubes, the crossbeam and the crooked lamp holder mount pads on top, between lamp stand and pedestal is to connect with hinge 4, when lamp stand is vertical state, a through hole that aligns is just in time arranged on lamp stand and pedestal, and the bolt 10 and the nut of the available one logical heart are connected and fixed.Control the bending rotation of lamp stand between lamp stand and pedestal with a controlled reduction gearing mechanism, the transmission mechanism of this deceleration is made up of first-stage worm gear worm speed-down and primary gear speed reducing, be connected into the relation of synchronous rotation between worm gear 5, worm gear hinge 4 and the lamp stand 2 with binding, the axle of pinion 7 also is equipped with dismountable crank 8 on the spindle nose that pedestal exposes outside, worm screw and gear wheel 6 are coaxial and be fixedly connected, and dumpling axle, worm shaft and the pinion shaft of worm gear all uses bearing support 9 to be contained on the inwall of pedestal.By hand crank, through gear reduction, pass to worm gear through worm screw and slow down once more, lamp stand can bending and slowly fall, and the workman can operate calmly, and work finishes and lamp stand shaken again, and installs the bolton of leading to the heart when aligning through hole.The characteristics that the lamp stand of this pattern has novel form, is convenient to operate, improve workman's condition of work, do not damage greenery patches or other facility especially have the universal significance of promoting the use of in the now of beautifying the environment energetically.

Claims

1. but the light pole of a bending, it is made up of pedestal (1), lamp stand (2) and illuminating lamp (3), it is characterized in that it lamp stand and pedestal between link with hinge (4), one through hole that aligns mutually and fastening with a bolt (10), nut is arranged on lamp stand and the pedestal when lamp stand is vertical state, and the bending action of lamp stand is to be controlled by the controlled reducing gear transmission of a cover.

2. but according to the light pole of the described bending of claim 1, the controlled speed reduction gearing that it is characterized in that it is paid with the one-level gear pair institute of slowing down by first-stage worm gear and is constituted, its worm gear (5) is contained on the hinge of lamp stand, be connected into the relation of synchronous rotation between lamp stand, hinge and the worm gear with binding, worm screw is coaxial and be fixedly connected with gear wheel (6), and pinion (7) axle is equipped with dismountable crank (8) on the spindle nose that pedestal exposes.
