DETAILED DESCRIPTION

[0022] like Figure 1-Figure 5As shown, the utility model provides a technical solution: a high-strength projector thin-walled shell, including a body 1, a cover plate 2 is arranged on the body 1, and the cover plate 2 is installed by pushing it downward, and a fastening bolt 3 is arranged inside the cover plate 2. By tightening the fastening bolt 3, the position of the extrusion rod 52 and the arc plate 63 can be fixed to complete the installation, a fixing frame 4 is fixedly installed on the bottom wall of the cover plate 2, a stabilizing mechanism 5 is arranged on the body 1 and the cover plate 2, and an installation mechanism 6 is arranged on the body 1 and the cover plate 2.

[0023] In this embodiment, a stabilizing mechanism 5 is provided on the body 1 and the cover plate 2. By squeezing the end of the support rod 54 through the hinged plate 55 in the stabilizing mechanism 5, the slider 51 can drive the squeezing rod 52 on the outer wall to move toward the outside of the fixed frame 4 to squeeze the inner wall of the body 1, which can make the installation more stable. At the same time, during disassembly, the elastic force of the supporting spring 56 can drive the push block 57 to move upward to push out the guide rod 58, so as to facilitate the disassembly of the cover plate 2 for inspection.

[0024] In this embodiment, a mounting mechanism 6 is provided on the body 1 and the cover plate 2. By squeezing the top end of the arc plate 63 in the mounting mechanism 6, the arc plate 63 can be rotated and engaged into the interior of the card slot 64 to complete the installation. When disassembling, the elastic force of the torsion spring 62 can make the arc plate 63 rotate and reset to release the engagement.

[0025] The above-mentioned stabilizing mechanism 5 includes a slider 51, which is slidably connected to the inner wall of the fixed frame 4. An extrusion rod 52 is fixedly installed on the side wall of the slider 51. The inner wall of the body 1 can be squeezed by the two extrusion rods 52 to make the installation more stable. A return spring 53 is sleeved on the outer wall of the extrusion rod 52. One end of the return spring 53 is fixedly connected to the outer wall of the slider 51, and the other end of the return spring 53 is fixedly connected to the outer wall of the extrusion rod 52. The slider 51 is hinged to one end of the support rod 54, and the other end of the support rod 54 is hinged to the hinge plate 55. The end of the support rod 54 is squeezed by the hinge plate 55, so that the slider 51 drives the extrusion rod 52 on the outer wall to move to the outside of the fixed frame 4, the inner wall of the body 1 is fixedly connected to one end of the load-bearing spring 56, and a push block 57 is fixedly installed on the other end of the load-bearing spring 56. The elastic force of the load-bearing spring 56 can drive the push block 57 to move upward to push out the guide rod 58, so as to facilitate the disassembly of the cover plate 2 for inspection and maintenance. The push block 57 is slidably connected to the inner wall of the body 1, and a guide rod 58 is fixedly installed on the bottom wall of the cover plate 2. The guide rod 58 is located above the push block 57, and the push block 57 is squeezed and moved to the inside of the body 1 by the guide rod 58 to guide it to prevent deviation during installation.

[0026] The above-mentioned installation mechanism 6 includes a rotating rod 61, which is rotatably connected to the inner wall of the body 1. A torsion spring 62 is sleeved on the outer wall of the rotating rod 61. One end of the torsion spring 62 is fixedly connected to the inner wall of the body 1, and the other end of the torsion spring 62 is fixedly connected to the outer wall of the rotating rod 61. The elastic force of the torsion spring 62 can make the arc plate 63 rotate and reset to release the clamping. The outer wall of the rotating rod 61 is fixedly installed with the arc plate 63, and a clamping groove 64 is opened on the bottom wall of the cover plate 2. The clamping groove 64 is located above the arc plate 63. The top of the arc plate 63 is squeezed by the cover plate 2, so that the arc plate 63 can be rotated and clamped into the inside of the clamping groove 64 to complete the installation.

[0027] In this embodiment, the installation is performed by pushing the cover plate 2 downward, and then the outer wall of the hinge plate 55 is squeezed by the inner wall of the body 1, so that the hinge plate 55 squeezes the end of the support rod 54, and the slider 51 is hinged between the support rod 54 and the slider 51, so that the slider 51 drives the squeezing rod 52 on the outer wall to move to the outside of the fixed frame 4, and then the inner wall of the body 1 is squeezed by the two squeezing rods 52, so that the installation is more stable, and at the same time, the push block 57 is squeezed and moved to the inside of the body 1 by the guide rod 58 to guide it to prevent the installation from being offset. The cover plate 2 squeezes the top of the arc plate 63, causing the arc plate 63 to rotate, and then the arc plate 63 is snapped into the inside of the slot 64 to complete the installation. Finally, the fastening bolts 3 are tightened to fix the position of the extrusion rod 52 and the arc plate 63 to complete the installation. When dismantling is required, the fastening bolts 3 are loosened, and then the elastic force of the torsion spring 62 causes the arc plate 63 to rotate and reset to release the snapping. At the same time, the load-bearing spring 56 is in a compressed state, so that the load-bearing spring 56 drives the push block 57 to move upward to push out the guide rod 58, thereby facilitating the disassembly of the cover plate 2 for inspection.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
