detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

Referring to FIG. 1 to FIG. 4 , a lamp provided by a preferred embodiment of the present invention includes a housing 1 and a rotating mechanism 2 arranged outside the housing 1 . The rotating mechanism 2 includes a fixing member 21 , a bracket 22 , a screw 23 and a nut 24 .

As shown in Figures 1 and 2, the fixing piece 21 is columnar and fixed on the outer wall of the casing 1, and there is no need to provide a connecting hole on the casing 1, and the fixing piece 21 will not affect the sealing and waterproof performance of the casing 1 , to ensure the protection level of lamps. Preferably, as shown in FIG. 3 , the housing 1 has an axisymmetric structure, and the axial direction of the fixing member 21 is located on the symmetrical axis of the housing 1 to ensure the balance of the lamp.

As shown in Figure 2, the bracket 22 includes a first support plate 22a and a second support plate 22b fixedly connected, and the first support plate 22a is used for cooperating and fixedly connecting with an attachment. In this embodiment, the attachment is a vertical rod , Of course, the attachment can also be a wall or the like. Preferably, the first support plate 22a and the second support plate 22b are connected in an L-shape, and the two are integrally formed to facilitate processing and preparation. Further, reinforcing ribs 22c are provided between the first support plate 22a and the second support plate 22b to improve the structural strength of the bracket 22 .

As shown in FIG. 2 , a slot 210 for restricting the rotation of the nut 24 is provided on the peripheral surface of the fixing member 21 . The nut 24 is disposed in the slot 210 . After the nut 24 fails to use, it can be easily replaced with a new nut. In this embodiment, the slot 210 has two opposite side walls, both of which are plane and parallel to each other. The nut 24 is a hexagonal nut 24 , and two opposite planes on its peripheral surface are attached to two side walls respectively, so that the nut 24 is stuck in the locking groove 210 and cannot rotate.

A connection hole 211 leading to the slot 210 is defined on the end surface of the fixing member 21 , and a through hole 220 is formed on the second support plate 22 b. The screw 23 passes through the through hole 220 and the connecting hole 211 to be threadedly connected with the nut 24 in turn.

Since the nut 24 is restricted in the slot 210 and cannot rotate, the screw 23 is rotated to tighten the screw 23 and the nut 24 so as to fix the second support plate 22b to the fixing member 21 and fix the position of the lamp. In order to prevent the screw 23 from loosening after the screw 23 and the nut 24 are tightened, an anti-slip elastic washer 25 is provided between the nut of the screw 23 and the second support plate 22b to prevent the screw 23 from loosening.

Loosen the screw 23, and the casing 1 and the fixing member 21 rotate around the screw 23 to adjust the light emitting angle and realize the rotation function of the lamp. In order to ensure the flexibility of rotation, as shown in Figure 2 and Figure 4, a flat washer 26 is provided between the anti-slip elastic washer 25 and the second support plate 22b, and the flat washer 26 and the second support plate 22b can be connected during use. Dot solid lubricating oil in between.

As shown in FIG. 2 , a limiting protrusion 212 is provided on the peripheral surface of the fixing member 21 , and a limiting member corresponding to the limiting protrusion 212 is provided on the second support plate 22 b. Preferably, the limiting member is a limiting screw 27 threadedly connected to the second support plate 22b, the nut of which cooperates with the limiting protrusion 212 to prevent the housing 1 from rotating by 360 degrees and disconnecting the incoming wire of the lamp. In order to prevent the limit screw 27 from loosening, a limit anti-slip spring washer 28 is provided between the nut of the limit screw 27 and the second support plate 22b. In this embodiment, there are two limiting protrusions 212, which are arranged along the circumferential direction of the fixing member 21, so that the limiting member can rotate between the two limiting protrusions 212. By controlling the two limiting protrusions The positional relationship between 212 can define the rotation angle of the housing 1 .

In order to facilitate the cooperation between the limiting protrusion 212 and the limiting member 27 , the limiting protrusion 212 is arranged at the connection between the peripheral surface and the end surface of the fixing member 21 . In order to facilitate the circumferential movement of the limit screw 27 relative to the fixing member 21 , the fixing member 21 is cylindrical.

The implementation methods described above do not limit the protection scope of the technical solution. Any modifications, equivalent replacements and improvements made within the spirit and principles of the above embodiments shall be included in the protection scope of the technical solution.
