[0002] A support frame is a shelf or bracket used to support, fix or build other objects. A support frame is usually made of strong materials such as metal, wood or plastic to provide support and stability. The design of the support frame can vary according to specific uses and needs. It can be a simple structure or a complex multi-functional design. Support frames are widely used in various fields, such as construction engineering, stage construction, photography, furniture manufacturing, etc., to support and fix objects. The design and material selection of the support frame usually depend on factors such as the weight, shape and use environment of the object to be supported.

The inner wall of the shell 1 is slidably connected with a fixing frame 3. The inner side wall of the fixing frame 3 is rotatably connected with a rotating shaft 4. One side of the outer surface of the rotating shaft 4 is fixedly connected with a supporting plate 5. One side of the outer surface of the rotating shaft 4 is provided with a first limiting groove.

[0024] In this embodiment, a limiting frame 6 is provided on the upper surface of the fixing frame 3, one end of the limiting frame 6 passes through the upper surface of the fixing frame 3 and extends to one side of the inner wall of the fixing frame 3, one end of the limiting frame 6 is fixedly connected to the limiting block 7, and the upper surface of the fixing frame 3 is rotatably connected with a screw rod 8, which is threadedly connected to the limiting frame 6.

[0025] When in use, the fixing frame 3 can drive the support plate 5 to slide out of the shell 1 when the inner wall of the shell 1 slides upward. The support plate 5 can rotate the rotating shaft 4 so that the support plate 5 and the shell 1 are in a vertical state. The screw 8 is screwed to make it and the limiting frame 6 move in a threaded manner and make the limiting frame 6 move downward to drive the limiting block 7 to be inserted into the first limiting groove, thereby limiting the rotating shaft 4 and the support plate 5. Electrical appliances and other equipment can be placed on the support plate 5. When the support plate 5 is not used, the reverse operation can be performed and the fixing frame 3 can be slid into the shell 1 to store the support plate 5, thereby reducing the overall space occupied by the support frame.

[0026] In this embodiment, connecting blocks are fixedly connected to both sides of the fixing frame 3 , the connecting blocks are slidably connected to the through slots 2 , and an engaging plate 9 is fixedly connected to one end of the connecting block.

[0027] When in use, the engaging plate 9 can drive the fixing frame 3 to move up and down when sliding up and down through the connecting block and the through slot 2 .

[0028] In this embodiment, side frames 10 are fixedly connected to both sides of the housing 1, a fixed shaft 11 is rotatably connected to the inner wall of the side frame 10, a worm gear 12 is fixedly connected to one side of the outer surface of the fixed shaft 11, and the worm gear 12 is meshed with the meshing plate 9.

[0029] During specific use, the worm wheel 12 can mesh with the meshing plate 9 when rotating to drive the meshing plate 9 to move.

[0030] In this embodiment, a baffle plate 13 is fixedly connected to the inner wall of the side frame 10, and a worm 14 is rotatably connected to one side of the baffle plate 13. The worm 14 is meshingly connected to the worm wheel 12. One end of the worm 14 passes through the inner wall of the side frame 10 and extends to one side of the side frame 10. One end of the worm 14 is fixedly connected to a turntable 15.

[0031] During specific use, the rotating disk 15 can be rotated to drive the worm 14 to rotate and make the worm 14 mesh with the worm wheel 12 , so that the worm wheel 12 can mesh with the meshing plate 9 .

[0032] In this embodiment, a sleeve frame 16 is fixedly connected to the back of the housing 1 , a connecting plate 17 is slidably connected to the inner wall of the sleeve frame 16 , and a second limiting groove is formed on the inner surface of the connecting plate 17 .

[0033] During specific use, the connecting plate 17 can slide on the sleeve frame 16 through the sliding connection with the sleeve frame 16 .

[0034] In this embodiment, a slide groove 18 is provided on the back of the housing 1 , and a movable plate 19 is slidably connected to the inner wall of the slide groove 18 .

[0035] During specific use, the movable plate 19 can be inserted into the second limiting groove when sliding along the sliding groove 18 to both sides and limit the connecting plate 17 .

[0036] In this embodiment, both ends of the rotating drum 101 are threadedly connected with threaded rods 20 , and one end of the threaded rod 20 is fixedly connected to the movable plate 19 .

[0037] During specific use, rotating the rotating drum 101 can make it perform threaded motion with the threaded rods 20 at both ends. Since the threaded rod 20 is fixedly connected to the movable plate 19, the threaded rod 20 can be limited, so that the threaded rod 20 drives the movable plate 19 to slide along the slide groove 18 under the threaded motion of the threaded rod 20 and the rotating drum 101.

[0038] Working principle: During use, when the turntable 15 is rotated, the worm 14 can be driven to rotate and the worm 14 can be meshed with the worm wheel 12, so that the worm wheel 12 can mesh with the meshing plate 9. When the meshing plate 9 slides up and down through the connecting block and the through-slot 2, the fixing frame 3 can be driven to move up and down. When the fixing frame 3 slides upward on the inner wall of the shell 1, the support plate 5 can be driven to slide out of the shell 1. The rotating shaft 4 is rotated through the support plate 5 so that the support plate 5 and the shell 1 are in a vertical state. The screw 8 is screwed to make it threaded with the limit frame 6 and the limit frame 6 moves downward to drive the limit block 7 to be inserted into the first limit groove, thereby limiting the rotating shaft 4 and the support plate 5. Electrical appliances and other equipment can be placed on the support plate 5. When the support plate 5 is not applicable, the reverse operation is performed. The fixing frame 3 can be slid into the shell 1 to store the support plate 5, reducing the space occupied by the entire support frame and making it convenient to adjust the height of the support plate 5. The connecting plate 17 can be connected to the wall. The connecting plate 17 can slide on the sleeve 16 through the sliding connection with the sleeve 16. Rotating the rotating drum 101 can make it perform threaded movement with the threaded rods 20 at both ends. Since the threaded rod 20 is fixedly connected to the movable plate 19, the threaded rod 20 can be limited, so that under the threaded movement of the threaded rod 20 and the rotating drum 101, the threaded rod 20 drives the movable plate 19 to slide along the slide groove 18. When the movable plate 19 slides along the slide groove 18 to both sides, it can be inserted into the second limiting groove and limit the connecting plate 17, which is convenient for adjusting the distance between the entire support frame and the wall.
