Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment of the utility model discloses projecting lamp that projection angle is adjustable.

Referring to fig. 1 and 2, a projection angle adjustable projection lamp includes a plurality of rows of parallel lamps and a slat 2 connecting the plurality of rows of lamps, in this embodiment, two rows of parallel projection lamps 1 are taken as an example, two sides of the lamps are rotatably connected to the slat 2 through bolts, a friction plate 3 is clamped between the slat 2 and the lamps, a friction surface of the friction plate 3 contacts with the lamps, a groove 31 is formed on the friction plate 3, a convex plate 21 is formed on the slat 2, and the convex plate 21 is inserted into the groove 31.

When the bolt is tightened, friction disc 3 and the increase of lamps and lanterns frictional force, the people applys external force and rotates, rotates back lamps and lanterns and receive frictional force no longer to rotate to form fixed projection angle, slat 2 rotates and is connected with curb plate 4, and slat 2 and curb plate 4 rotate through the pivot and connect, arc groove 6 has been seted up on the curb plate 4, and arc groove 6 encircles the pivot setting, and arc 6's radian is accomplished to be greater than 180 degrees as far as possible, wear to be equipped with stop screw 5 in the arc groove 6, screw threaded connection is in slat 2, when needs adjustment slat 2 is for the angle of curb plate 4, not hard up stop screw 5 rotates slat 2 to required position, later screws up stop screw 5 again, and stop screw 5 closely compresses tightly curb plate 4 and slat 2 to increase curb plate 4 and slat 2's frictional force.

A bottom plate 7 is rotatably connected between the two side plates 4, a seat plate 8 is rotatably connected below the bottom plate 7, an insert rod 9 is vertically fixed on the seat plate 8, a thrust bearing 11 is sleeved outside the insert rod 9, and the upper surface and the lower surface of the thrust bearing 11 are respectively in contact with the seat plate 8 and the bottom plate 7.

The upper end of inserted bar 9 is provided with the screw thread, inserted bar 9 threaded connection has two nuts 10, bottom plate 7 and thrust bearing 11 are established to nut 10 and bedplate 8 clamp.

When the scene need not horizontal level all the time and rotates two rows of projecting lamps 1, rotate bottom plate 7 and make bedplate 8 be located the top of bottom plate 7, curb plate 4 contact ground, set up bolt hole and bolted connection foreign object on the curb plate 4, can be with the permanent fixed position of projecting lamp 1.

When the frequent horizontal rotation projecting lamp 1 of on-the-spot needs, bedplate 8 contacts and fixes at the scene, two not hard up nuts 10, rotate bottom plate 7, drive two 1 turned angle of projecting lamp, again as required the operation such as 1 relative slat 2 of specific adjustment projecting lamp, treat the debugging back that finishes, screw up two nuts 10, form two nut 10 structures, nut 10 compresses tightly bottom plate 7, make bottom plate 7 not relative nut 10 rotate, and because two nut 10 locking looseness, the nut 10 of hugging closely bottom plate 7 can not relative inserted link 9 and rotate, thereby indirectly play the effect of stabilizing bottom plate 7 and bedplate 8 relatively stable.

The embodiment of the utility model provides an implementation principle of projecting lamp that projection angle is adjustable does: when the two rows of projection lamps are projected onto a wall, the projection angles can be respectively adjusted relative to the strip plates 2, focusing projection, dispersing projection and the like can be achieved, and in addition, the angle can be adjusted relative to the side plates 4 by combining the strip plates 2, so that the rotation angles of the two rows of projection lamps are further expanded;

when lateral rotation is required, the two rows of projector lamps rotate relative to the base plate 8 so as to be able to rotate horizontally and laterally.
