Detailed Description
As shown in fig. 1, the rotating structure of the lamp provided by the invention is positioned at the end part of the lamp, and mainly comprises an end cover 1, a fixed seat 2 and a sealing cover 3 which are sequentially arranged at the outer side of the end cover 1, wherein the fixed seat 2 is in rotating connection with the end cover 1, the sealing cover 3 is fixedly connected with the end cover 1 and is embedded between the fixed seat 2, a first rotating piece is arranged on the end cover 1, the sealing cover 3 or a connecting part thereof, a second rotating piece is arranged on the fixed seat 2, at least one of the first rotating piece and the second rotating piece has elasticity, and the first rotating piece and the second rotating piece are elastically clamped; one of the first rotating member and the second rotating member is provided with an elastic sheet 4, the elastic sheet 4 relatively rotates along the periphery of the other rotating member, and a limiting clamping groove 21 for elastic deformation movement of the elastic sheet 4 is formed in an inner cavity formed by enclosing the sealing cover 3, the fixing seat 2 and the end cover 1.
In the embodiment shown in fig. 2, the first rotating member is a gear wheel 5 fixedly attached to the outside of the end cap 1, preferably the gear wheel 5 is integrally formed with the end cap 1. The second rotating piece is a spring piece 4 arranged on the fixed seat 2. In addition, the gear 5 may be disposed on a side of the cover 3 facing the cover 1, and the gear 5 acts on the fixing base 2 after the cover 1 and the cover 3 are fixedly connected. The structure of the fixing seat 2 is shown in fig. 3, a limit hole 22 and a limit clamping groove 21 which are communicated are formed on the fixing seat 2, after the fixing seat 2 is connected with the end cover 1, the gear 5 is sleeved in the limit hole 22, the elastic sheet 4 is arranged in the limit clamping groove 21, and the elastic sheet 4 can be matched and clamped with the gear 5. The gear 5 is arranged in a circular shape and rotates in the limiting hole 22, and a rotating shaft L of the end cover 1 rotating relative to the fixed seat 2 penetrates through the rotating center of the gear 5. In one embodiment of the present invention, the limiting hole 22 is a circular hole, and the limiting slot 21 is an arc slot connected to the limiting hole 22.
As shown in fig. 2 and 3, the elastic piece 4 includes a protruding portion 41 and a supporting portion 42, and the supporting portion 42 elastically abuts against the inner wall of the limit catch groove 21, so that the protruding portion 41 protrudes inward to abut against the gear 5. In one embodiment of the present invention, the supporting portions 42 are formed at both sides of the elastic sheet 4, the supporting portions 42 are bent to protrude outward, and the protruding portions 41 are formed at the intersections of the two supporting portions 42.
Preferably, the spring plate 4 is made of an elastic metal. Because the elastic sheet 4 has elasticity, the supporting parts 42 on two sides are abutted against the inner wall of the limit clamping groove 21 along the direction facing the outer side of the lamp, and are subjected to reaction force, so that the protruding part 41 is propped against the gear 5, the top end of the protruding part 41 is clamped between two gear teeth of the gear 5 in a tip mode, and therefore under the condition that no external force is applied, the elastic sheet 4 can clamp the gear 5 to limit rotation.
When an external force is applied to adjust and rotate the lamp, the end cover 1 rotates relative to the fixed seat 2 to enable the gear teeth of the gear 5 to press the protruding portion 41 of the elastic piece 4, the elastic piece 4 is stressed and deformed, the protruding portion 41 is bent towards the inner wall of the limiting clamping groove 21, the supporting portion 42 of the elastic piece 4 is in a bent state, the elastic piece 4 is unfolded towards two ends, and therefore the top ends of the protruding portions 41 are separated from the gear teeth, and rotation limitation is relieved. When the gear 5 rotates a certain angle and reaches a required adjustment angle, the external force is removed, the elastic sheet 4 is reset without being stressed, the elastic sheet 4 is contracted inwards to restore the original shape, and the protruding part 41 is clamped between the gear teeth again.
In an alternative of the invention, the end cap 1 or the cover 3 limits the rotation of the holder 2. In the embodiment shown in fig. 2, the end cover 1 and the cover 3 are fixedly connected through the fastening screw 6, and the end cover 1 and the cover 3 are matched to form the rotating groove 7, so that the fixed seat 2 is interfered by the opening edge of the rotating groove 7 after rotating a certain angle, and the fixed seat 2 is limited to move within the opening range of the rotating groove 7. In addition, the rotation of the fixing base 2 can be interfered by other limiting structures.
Compared with the prior art, the elastic sheet 4 is not fixed on a certain part, but moves in an area, and is changed between a deformed state and a reset state along with the stress condition, and the elastic sheet 4 elastically deforms in the limit clamping groove 21 to cope with the extrusion force given by the gear 5, so that the interference degree is reduced, and the wear is not easy, and the long-term use is suitable. During adjustment, the gears 5 rotate tooth by tooth and finally the teeth and the spring plates 4 are clamped and positioned, so that the rotation adjustment precision is high.
Further, in order to provide a spreading space for the elastic sheet 4 to deform after being stressed, the inner wall of the limiting clamping groove 21 is spaced from the two end parts of the elastic sheet 4.
In addition to the above-mentioned rotating structure, it will be understood that the positions of the gear 5, the spring plate 4 and the limiting slot 21 may be other, for example, the limiting slot 21 and the spring plate 4 may be disposed on the end cover 1, and the gear 5 may be disposed on the fixing base 2 opposite to the end cover 1.

Wire grooves 8 are formed in the end cover 1 and the sealing cover 3, and the wires 500 pass through the end cover 1 and the sealing cover 3 through the wire grooves 8 and synchronously rotate along with the lamp body 100, so that wire winding can be prevented.
With the rotation of the lamp, the protruding part 41 on the elastic sheet 4 is clamped between the gear teeth of the gear 5, and the angle adjusted according to the requirement is rotated by a certain number of teeth. Preferably, the fixed seat 2 is marked with an arrow, the sealing cover 3 is marked with an angle, and the angle can be adjusted in place by reading the angle.
In one embodiment of the lamp, the fixing base 2 comprises a mounting plate 23, the mounting plate 23 extends away from the rotation axis L, and the mounting plate 23 forms an included angle with the rotation plane of the fixing base 2, as shown in fig. 4, the mounting plate 23 is perpendicular to the rotation plane of the fixing base 2. In the case of a container application, for example, the lamp of the present invention is a strip-shaped lamp, the two end fixing bases 2 of which are fixed to the bottom surface of the container laminate from bottom to top through the mounting plate 23, and the lamp housing 400 irradiates the lower layer of the article downward. The lamp body 100 may be rotated to change the irradiation angle as needed. Further, the free end of the end cap 1 remote from the axis of rotation L is offset by a distance greater than the distance of the mounting plate 23, such that when the lamp is rotated, the mounting plate 23 interferes with the end cap 1 to limit the range of rotation.
