Beneficial effect
1, take over a business to be fixed on roof, positioning disk is fixed on below by adjustable column from bottom to top, regulating tank is provided with in the lower end of adjustable column, adjustment means is inserted regulating tank, just can change positioning disk and distance between taking over a business, when positioning disk is moved down, positioning disk can only move to the nut propping up the locating dowel being fixed on, thus maintenance personal is keeped in repair from the space of taking over a business between positioning disk electric component, after maintenance, pass through rotating regulating tools again, adjustable column is rotated, make positioning disk along the outer wall of adjustable column to rising, until top is to taking over a business.
Detailed description of the invention
As shown in Fig. 1 to Fig. 3, the pendent lamp that a kind of positioning disk can be elevated, primarily of taking over a business 1, open-topped cylindrical positioning disk 2, adjustable column 3, locating dowel 4, crystal and electric component composition, take over a business from bottom to top and be fixed on roof, the edge of positioning disk by opening on upper mode is pressed in from bottom to top, the outstanding fixed leg 11 of hollow is provided with downwards at the wall center of taking over a business down, the top of adjustable column is provided with nut, lower end is provided with the regulating tank matched with adjustment means, opening is provided with in the side of fixed leg, the diapire of fixed leg is provided with aperture and is greater than adjustable column mid diameter but the through hole being less than the nut regulated on capital, the nut of adjustable column enters fixed leg endoporus from the lateral opening of fixed leg, the main body of adjustable column is suspended on below adjustable column, the outer wall of adjustable column is provided with external screw thread, adjustment hole is provided with at positioning disk center, adjustment hole inwall is provided with the internal thread matched with the external screw thread on adjustable column, on positioning disk wall, be provided with the plural locating hole of symmetric arrays around locating hole, the corresponding locating dowel 4 of each locating hole, described locating dowel is with nut, and the diameter of nut is greater than the aperture of locating hole.
As shown in Fig. 4 to Fig. 5, during installation, positioning disk is shifted onto adjustable column end down from bottom to top, the lower end of adjustable column is made to aim at adjustment hole, by locating dowel by nut under mode insert the locating hole of positioning disk from bottom to top, by the end top of locating dowel to taking over a business to go up and being fixed on wall down, electric component is placed on positioning disk diapire upward, make the lamp hole on the lamp ball aligning positioning disk diapire of lamp sheet, throw inserted the regulating tank on adjustable column and rotate, adjustable column is rotated and positioning disk is moved until the top edge of positioning disk is pressed in from bottom to top, positioning disk wall is down provided with multiple hook, crystal is suspended on corresponding hook.
Described regulating tank is generally cross or in-line or hexagon, insert regulating tank with cross driver or a word bottle opener or hex tool to rotate, because adjustable column can rotate forward or backwards with adjustment means, external screw thread on adjustable column coincideing by the internal thread with adjustment hole inwall, the position of adjustment hole on adjustable column will be changed, positioning disk just can be made to move up or down.When positioning disk moves up, the upper limit of movement is that positioning disk withstands, when positioning disk moves down, because locating dowel is fixed on, the lower limit of positioning disk movement is the nut that positioning disk compresses locating dowel, at this moment, the lower end of adjustable column is positioned at below adjustment hole or adjustment hole, positioning disk and leave sufficient distance between taking over a business, electric component on positioning disk exposes, maintenance personal climbs up the ladder, just can the electric component above positioning disk be keeped in repair, after maintenance, reversely rotate with the adjustment hole of adjustment means insertion adjustable column again, positioning disk will constantly to rising, until positioning disk top is on taking over a business, keep in repair complete.
Adopt pendent lamp of the present invention, do not need crystal and positioning disk to remove during maintenance just to keep in repair the electric component on positioning disk, significantly can shorten the time of maintenance.
The length of described locating dowel is greater than more than the 10cm of the height of positioning disk.
The length of described adjustable column is greater than the length of locating dowel.
Be provided with below positioning disk and regulate trim 12, described trim open top, screw is provided with at adjustment trim bottom wall central, when positioning disk cover from bottom to top upper after, adjustment trim is pressed to the adjustable column end be positioned at below positioning disk from bottom to top, rotate and regulate trim, make adjustable column end enter the screw regulated on trim diapire.
Positioning disk center is provided with outstanding cylindrical projections downwards, and the adjustment hole of positioning disk runs through projection.In order to make adjustable column more firm with being threaded of adjustment hole, lengthening the length of adjustment hole, also just increasing the internal thread length of adjustment hole, prevent the screw thread long sliding tooth that later may cause too short service time.
Be positioned at the location trim 13 locating dowel below positioning disk being provided with and covering on positioning disk diapire from bottom to top, accordingly, positioning disk diapire be provided with locating slot, location trim and locating slot snap together.Location trim 13 has two kinds of set-up modes, and one is set as a ring cover, can all locating dowels be covered simultaneously, can also be set as a locating dowel one location trim.
Between the diapire and the nut of adjustable column of fixed leg, be provided with bearing 5, when adjustable column rotates, adjustable column is also with dynamic bearing to rotate, and reduces the motor power between adjustable column and fixed leg.Adjustable column is through the central through hole of bearing, and nut is positioned at above bearing, puts in fixed leg by adjustable column together with bearing from the side-wall hole of fixed leg, makes bearing between the nut and the diapire of fixed leg of adjustable column, and the cylinder of adjustable column is through bearing.
Described electric component mainly comprises transformer and lamp sheet, and lamp sheet is placed in after above positioning disk, and the lamp pearl on lamp sheet is corresponding with the light hole on positioning disk diapire.Lamp sheet selects LED sheet usually.Positioning disk diapire is also provided with downward lamp socket, and bulb is inserted on lamp socket from bottom to top, when needing repairing, first below positioning disk, takes off bulb, then is spun down by positioning disk, keep in repair above positioning disk.
Above-described embodiment is only used to interpretation purposes of the present invention, and is not limitation of the present invention, those skilled in the art, in essential scope of the present invention, makes a variety of changes or substitutes, also should belong to protection category of the present invention.
