Detailed Description

To facilitate an understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings and specific examples. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Example 1

Fig. 1 is an exploded view of the projector according to the present embodiment, fig. 2 is an assembled finished view of the projector according to the present embodiment, fig. 3 is a partial sectional view of the projector according to the present embodiment, and fig. 1 to fig. 3 are combined to provide a projector for high-brightness illumination in outdoor places, which is a flat structure as a whole, and includes a lamp body 1, a second bracket 2, and a second bracket 3. The lamp body is the main part of projecting lamp, and its shell is the casing 11 of sheet metal component, and inside forms a cavity, installs light source spare 12 and optical part 13 in the cavity, and optical part 13 covers in the top of light source spare 12, optimizes the light that light source spare 12 sent, makes its focus shine.

The shell 11 can adopt the sheet metal component that the aluminium alloy punching press formed, has stamped in advance at the bottom of shell 11 and has formed boss 111, and boss 111 is hemisphere or cuboid structure, refers to fig. 3, and its cross-section is semicircle or rectangle, mainly used and first support 2 carry out the riveting.

Fig. 4 shows a schematic diagram before assembly of the first bracket and the housing in the present embodiment, fig. 5 shows a schematic diagram of a structure of the first bracket in the present embodiment, as shown in fig. 4 and 5, the first bracket 2 has an L-shaped structure, and includes a first connecting portion 21 fixedly connected to the housing 11 and a second connecting portion 22 rotatably connected to the second bracket 3, in the present embodiment, the first connecting portion 21 is perpendicular to the second connecting portion 22, and in order to enhance the rigidity of the bending portion, a reinforcing rib 23 is further added. A groove 211 matching the boss 111 is provided on the first connection portion 21. When in connection, the boss 111 is pressed into the groove 211 and is pressed and expanded by external force to be deformed, and then the boss and the groove are riveted and fixed together.

Specifically, the groove 211 of the first bracket is aligned with the boss 111 of the shell, the height of opening and closing the die is adjusted, and the boss and the groove are riveted together by a punch.
