CN200920133549.2 has announced " a kind of light fixture rotation positioning device ", its purpose provides a kind of by the annular inside casing that connects with lamp body is rotated relative to housing, and on the annular inside casing, snap device is set, can make light fixture in the space, make things convenient for rotational positioning, and the adjusting of light fixture irradiating angle is easy and simple to handle, quick, accurately and reliably the light fixture rotation positioning device.The main points of this technical scheme are: described light fixture rotation positioning device comprises fixing annular housing, is nested in the housing and this housing is coaxial relatively horizontally rotates the annular inside casing of connection and be arranged on the annular inside casing also relatively this annular inside casing snap device in axial sliding; Wherein, evenly be provided with a plurality of teeth groove on the described housing top circumference, the annular inside casing can be connected with teeth groove buckle on the housing by described snap device.Yet its weak point is: fail to solve the adjusting rotational problems of lamp body at vertical direction.
Summary of the invention
The purpose of this utility model is, provide a kind of by regulating worm screw self axial rotation, make the engagement of worm screw and support gear, make the lamp body that connects with support relative to the annular inside casing along the support pivot to rotating, make light fixture rotate easily in the space, locate, and owing to exist frictional force to make gear drive be in self-locking state in transmission process, the adjusting of light fixture irradiating angle is easy and simple to handle, accurately and reliably, and after adjusting was finished, rotation direction had the light fixture rotation positioning device of auto-lock function.
Technical solution of the present utility model is described light fixture rotation positioning device, comprising: the annular housing that is connected with ceiling or wall mounted, be nested in the annular housing and be connected annular inside casing on the lamp body, be arranged on the rotation positioning device on the annular inside casing by support; Its special character is: described rotation positioning device is covered a pair of axle bed, is slotted, slots down along going up of axle bed one end bending forming by the corresponding lamp body support of inner ring of annular inside casing; Between last fluting, following fluting, be arranged with for the nested cavity of worm screw; And the face that the covers middle section of the axle bed other end be arranged with a plurality of gear teeth, the upper/lower terminal that are provided with on the termination of the pivot hole that articulates for support, support be equipped with the backstop cap and be set on fluting on the axle bed, down in the fluting and only at the worm screw composition of axial rotation.
As preferably:
The gear teeth on wrom tooth on the described worm screw and the support termination form the turbine and worm engaged transmission, and then drive the lamp body that support connects and rotate along the support pivot relative to the annular inside casing, make light fixture rotational positioning in the space.
The lower endcaps of described worm screw can be regulated with instrument.
Compared with prior art, advantage of the present utility model:
That the light fixture irradiating angle is regulated is easy and simple to handle, accurately and reliably, and regulate finish after, rotation direction has auto-lock function.Can make light fixture in the space, make things convenient for rotational positioning, need not extra locking.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
See also shown in the accompanying drawing, in the present embodiment, described light fixture rotation positioning device comprises: annular housing 1 is fixed on ceiling or the wall by brace disposed thereon 11, annular inside casing 2 is connected with the ceiling relative fixed by being nested in annular housing 1.Being fixed on by rivet can be along the support 31 of rivet direction axial rotation on the annular inside casing 2; Be nested in the annular housing 1 and be connected annular inside casing 2 on the lamp body 3, be arranged on the rotation positioning device 4 on the annular inside casing 2 by support 31; Described rotation positioning device 4 covers a pair of axle bed 41, going up fluting 411, slot 412 down along axle bed 41 1 end bending formings by the corresponding lamp body support 31 of the inner ring of annular inside casing 2; At last fluting 411, slot 412 and be arranged with down for worm screw nested cavity 413; Be equipped with backstop cap 51 and be set on and slot 411 on the axle bed, slot in 412 down and only form the worm screw 5 of axial rotation and be arranged with a plurality of gear teeth 311, the upper/lower terminal that are provided with on the termination of the pivot hole 414 that articulates for support 31, support at the face that the covers middle section of axle bed 41 other ends, the backstop cap 51 of worm screw 5 by two ends is from last fluting 411, slot and 412 slip into to be fixed on and slot 411, slot down in 412 down.The gear teeth 311 of support 31 block worm screw 5 prevent from annular inside casing 2 fluting 411, slot and skid off 412 down.
Wrom tooth 52 on the described worm screw 5 forms the turbine and worm engaged transmission with the gear teeth 311 on the support termination, and then drives the lamp body 3 that support 31 connects and rotate along support pivot 32 relative to annular inside casing 2, makes light fixture rotational positioning in the space.
The lower endcaps of described worm screw 5 can be regulated with the Phillips screwdriver (not shown).
In other embodiments, annular inside casing 2 also can be fixedlyed connected by alternate manners such as rivet, screws with support 31.Annular housing 1 also can directly pass through screw or alternate manner and ceiling or wall mounted.Axial restraint between annular housing 1 and the annular inside casing 2 also can be fixed by alternate manner, and instruments such as also available straight screwdriver of the adjusting of worm screw 5 or spanner are realized self rotating.
The action principle of the rotation positioning device that present embodiment provides is:
Regulate worm screw 5 with Phillips screwdriver, make that worm screw 5 slots 411 on annular inside casing 2, the axial rotation in 412 of slotting down, when annular inside casing 2 axial rotation, the spiral helicine wrom tooth 52 of worm screw 5 self is that the gear on worm engagement is rotated with the gear teeth 311 on the support, make support 31 with respect to perforation direction axial rotation, and then drive lamp body 3 vertically rotate with respect to annular inside casing 2.
In whole transmission process, because the gear on worm transmission, but self-locking so lamp body 3 can be realized self-locking after adjusting is finished, is promptly regulated and is finished the location of lamp body 3 in the space.
