DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] See also Figure 1-5 The utility model provides a technical solution: a telescopic net mechanism for building construction safety protection, including a vertical rod 1 and a telescopic grid 2, two vertical rods 1 are provided, the telescopic grid 2 is arranged between the two vertical rods 1, the bottoms of the two vertical rods 1 are fixedly connected with a support box 3 and a support block 4 respectively from left to right, and a handle 18 is fixedly connected to the top of the left vertical rod 1.

[0020] Furthermore, in order to facilitate the storage and limiting of the device, a closing positioning mechanism 5 is provided between the support box 3 and the support block 4, and the closing positioning mechanism 5 includes a U-shaped frame 52, the U-shaped frame 52 is fixedly arranged on one side of the support block 4, and the front and rear sides of the U-shaped frame 52 are both provided with positioning slots 53, and the front and rear sides of one side of the support box 3 are elastically slidably connected with a positioning plug 51 used in conjunction with the positioning slot 53, one side of the U-shaped frame 52 is fixedly connected to the side of the pressure plate 11, and the front and rear sides of one side of the support box 3 are both connected A limiting sleeve 12 that is slidably adapted to the positioning block 51 is fixedly connected through the bracket, a first return spring 13 is fixedly connected between the adjacent limiting sleeves 12 and the positioning block 51, a limiting groove 14 is opened at the top of the inner cavity of the support box 3, a limiting slider 15 is slidably connected inside the limiting groove 14, a second return spring 16 is fixedly connected between the limiting slider 15 and the limiting groove 14, the bottom of the limiting slider 15 is fixedly connected to the top of the tooth plate 8, and a pull rod 17 is fixedly connected to the top of the positioning block 51.

[0021] Furthermore, in order to facilitate and save effort in moving the device close to the ground, a rotating rod 6 is rotatably connected between the front and rear sides of the inner cavity of the support box 3 through a bearing, a gear 7 is fixedly connected to the surface of the rotating rod 6, and a toothed plate 8 meshing with the gear 7 is slidably connected to the top of the inner cavity of the support box 3. A mounting plate 9 is fixedly connected to the surface of the rotating rod 6 and located at the front and rear sides of the gear 7. A pulley 10 is installed on the top of the mounting plate 9, and the pulley 10 extends to the top of the support box 3, and a pressure plate 11 used in conjunction with the toothed plate 8 is fixedly connected to one side of the closing positioning mechanism 5.

[0022] When the two vertical rods 1 are to be stored and moved, the operator will close the two vertical rods 1, so that the telescopic grid 2 will close and reduce the floor space. When the two vertical rods 1 are closed, the U-shaped frame 52 on the side of the support block 4 moves and squeezes toward the positioning block 51 on the side of the support box 3, so that the positioning slots 53 on the front and rear sides of the U-shaped frame 52 are elastically limited with the positioning block 51. While the U-shaped frame 52 and the positioning block 51 move and limit, the U-shaped frame 52 synchronously drives the pressure plate 11 to squeeze the tooth plate 8. The tooth plate 8 is forced to move and engage with the gear 7, so that the gear 7 drives the rotating rod 6 to rotate 90 degrees to the left, and the rotating rod 6 drives the pulley 10 to rotate 90 degrees. Finally, the operator uses the handle 18 to slightly tilt the two closed vertical rods 1 to the left, so that the pulley 10 contacts the ground, and finally pulls the handle 18 to cause the pulley 10 to drive the vertical rod 1 to slide on the ground.
