The adjustment of the lighting angle of the lamp is simple, accurate and reliable, and after the adjustment is completed, the rotation direction of the lamp has a self-locking function. .

The technical solution of the utility model is that the rotating positioning device of the lamp includes: a ring-shaped outer frame fixedly connected to the ceiling or the wall, a ring nested in the ring-shaped outer frame and connected to the lamp body through a bracket Shaped inner frame, a rotary positioning mechanism arranged on the annular inner frame; its special feature is that the rotary positioning mechanism is covered by a pair of shaft seats corresponding to the lamp body bracket on the inner circle of the annular inner frame, along the axis The upper slot and the lower slot are bent and formed at one end of the seat; the cavity for the worm nesting is recessed between the upper slot and the lower slot; and the bracket is recessed in the central area of the covering surface at the other end of the shaft seat Pivot pivot hole, a plurality of gear teeth on the end of the bracket, stop caps are provided at the upper and lower ends, and they are inserted into the slots on the shaft seat and the bottom slots, and only rotate in the axial direction composed of worms.

As preferred:

The worm teeth on the worm and the gear teeth on the end of the bracket form a worm gear meshing transmission, and then drive the lamp body connected to the bracket to rotate relative to the ring-shaped inner frame along the pivot of the bracket, so that the lamp is rotated and positioned in the space.

The lower end cap of the worm can be adjusted with tools.

Compared with the prior art, the utility model has the following advantages:

The adjustment of the illumination angle of the lamp is simple, accurate and reliable, and after the adjustment is completed, the rotation direction has a self-locking function. The lamp can be rotated and positioned conveniently in the space without additional locking.

Detailed ways

The utility model will be described in further detail below in conjunction with the accompanying drawings:

Please refer to the accompanying drawings, in this embodiment, the rotating positioning device of the lamp includes: the circular outer frame 1 is fixed on the ceiling or the wall through the connecting piece 11 arranged thereon, and the circular inner frame 2 By being nested in the ring-shaped outer frame 1, it is relatively fixedly connected with the ceiling. The bracket 31 fixed on the circular inner frame 2 by rivets and can rotate axially along the rivet perforation direction; the circular inner frame 2 nested in the circular outer frame 1 and connected to the lamp body 3 through the bracket 31 1. The rotation positioning mechanism 4 arranged on the ring-shaped inner frame 2; the rotation positioning mechanism 4 is covered with a pair of shaft seats 41 corresponding to the lamp body bracket 31 on the inner ring of the ring-shaped inner frame 2, and one end of the shaft seat 41 The upper slot 411 and the lower slot 412 are formed by bending; the cavity 413 for the nesting of the worm is recessed between the upper slot 411 and the lower slot 412; A pivot hole 414 for the pivot connection of the support 31, a plurality of gear teeth 311 provided on the end of the support, stop caps 51 are provided at both ends of the upper and lower ends, and the slots 411 and the lower openings are set on the shaft seat. The worm screw 5 in the groove 412 and only rotates in the axial direction is formed, and the worm screw 5 slides into and is fixed in the upper groove 411 and the lower groove 412 from the upper groove 411 and the lower groove 412 through the stop caps 51 at both ends. The gear teeth 311 of the bracket 31 block the worm 5 to prevent from sliding out from the upper slot 411 and the lower slot 412 of the annular inner frame 2 .

The worm gear 52 on the worm 5 and the gear teeth 311 on the end of the bracket form a worm gear meshing transmission, and then drive the lamp body 3 connected to the bracket 31 to rotate relative to the ring-shaped inner frame 2 along the bracket pivot 32, so that the lamp is in the Rotational positioning in space.

The lower cap of the worm 5 can be adjusted with a Phillips screwdriver (not shown).
