DETAILED DESCRIPTION
[0023] like Figure 1-Figure 5As shown, the utility model provides a technical solution: a safety protection structure, including a protection plate 1, the interior of the protection plate 1 passes through a telescopic plate 2, the interior of the protection plate 1 is rotatably connected with an adjusting rod 3, a gear 4 is fixedly sleeved on the outer wall of the adjusting rod 3, a rack 5 is fixedly installed on the side wall of the telescopic plate 2, the rack 5 is meshed with the gear 4, and the gear 4 is driven by the adjusting rod 3 to rotate counterclockwise, so that the rack 5 can drive the telescopic plate 2 to move toward the outside of the protection plate 1 to extend, an adjusting mechanism 6 is arranged inside the protection plate 1, and a reset mechanism 7 is arranged inside the protection plate 1.
[0024] In this embodiment, an adjusting mechanism 6 is provided inside the protective plate 1. By squeezing the arc-shaped outer wall of the block 65 in the adjusting mechanism 6 by the gear 4, the block 65 can drive the sleeve plate 64 to move upward and flip so that the limit is released, thereby facilitating the adjustment of the position of the telescopic plate 2. At the same time, by re-engaging the block 65 in the slot 67, the sleeve 66 can drive the gear 4 on the outer wall of the adjusting rod 3 to be fixed, thereby fixing the position of the telescopic plate 2 for easy use.
[0025] In this embodiment, a reset mechanism 7 is provided inside the protective plate 1. By pressing the reset rod 72 in the reset mechanism 7, the reset rod 72 can squeeze the bottom wall of the sleeve plate 64, and the sleeve plate 64 drives the block 65 to rotate so that the limit is released, so that the adjustment rod 3 drives the gear 4 to rotate clockwise to move the telescopic plate 2 back to the inside of the protective plate 1, so as to facilitate re-adjustment and use.
[0026] The above-mentioned adjustment mechanism 6 includes a fixed block 61, and the fixed block 61 is fixedly installed with the protective plate 1. A rotating rod 62 is rotatably connected to the inner wall of the fixed block 61, and a torsion spring 63 is sleeved on the outer wall of the rotating rod 62. One end of the torsion spring 63 is fixedly connected to the inner wall of the fixed block 61, and the other end of the torsion spring 63 is fixedly connected to the outer wall of the rotating rod 62. The elastic force of the torsion spring 63 can make the rotating rod 62 drive the clamping block 65 on the bottom wall of the sleeve plate 64 to reset. The sleeve plate 64 is fixedly sleeved on the outer wall of the rotating rod 62, and the clamping block 65 is fixedly installed on the bottom wall of the sleeve plate 64. The side wall of the block 65 is arranged in an arc shape. By rotating the gear 4 counterclockwise to squeeze the arc-shaped outer wall of the block 65, the block 65 can drive the sleeve 64 to move upward and flip so that the limit is released, which is convenient for adjusting the position of the telescopic plate 2. A sleeve 66 is fixed on the outer wall of the adjusting rod 3. A slot 67 is provided on the outer wall of the sleeve 66. The slot 67 is provided in a circular array on the outer wall of the sleeve 66. By re-engaging the block 65 in the inside of the slot 67, the sleeve 66 can drive the gear 4 on the outer wall of the adjusting rod 3 to be fixed.
[0027] The above-mentioned reset mechanism 7 includes a round rod 71, which is rotatably connected to the inner wall of the protective plate 1. A reset rod 72 is fixedly passed through the inside of the round rod 71. The reset rod 72 is configured to be bent. The reset rod 72 is located at the bottom of the sleeve plate 64. The outer wall of the reset rod 72 is fixedly connected to one end of a reset spring 73. By pressing the reset rod 72 downward to rotate, the reset rod 72 can squeeze the bottom wall of the sleeve plate 64, so that the sleeve plate 64 drives the block 65 to rotate so that the limit is released. The other end of the reset spring 73 is fixedly connected to the inner wall of the protective plate 1.
[0028] In this embodiment, when the elevator door is large and the guard plate 1 needs to be widened, the adjusting rod 3 drives the gear 4 to rotate counterclockwise, and then the gear 4 is meshed with the rack 5, so that the rack 5 drives the telescopic plate 2 to move toward the outside of the guard plate 1 to extend. During the adjustment, the gear 4 rotates counterclockwise to squeeze the arc-shaped outer wall of the block 65, so that the block 65 drives the sleeve plate 64 to move upward and flip so that the limit is released, thereby facilitating the adjustment of the position of the telescopic plate 2. After the adjustment is completed, the elastic force of the torsion spring 63 drives the rotating rod 62 to drive the bottom wall of the sleeve plate 64 upward. The block 65 is reset, and then the block 65 is re-engaged in the slot 67 through the block 65, so that the sleeve 66 drives the gear 4 on the outer wall of the adjusting rod 3 to be fixed, and then the position of the telescopic plate 2 is fixed for easy use. When use is completed, the reset rod 72 is pressed downward to rotate, and the reset rod 72 squeezes the bottom wall of the sleeve plate 64, so that the sleeve plate 64 drives the block 65 to rotate so that the limit is released, and then the adjusting rod 3 drives the gear 4 to rotate clockwise to move the telescopic plate 2 back to the inside of the protective plate 1, which is convenient for adjustment and use again.
