Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0022] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 As shown in FIG-4 , an embodiment of the present invention provides an upward-flipping protective railing, comprising a main body mechanism 1 and an upward-flipping mechanism 2;

[0024] The flipping mechanism 2 is installed on the main body mechanism 1, and the main body mechanism 1 also includes a fixed frame 11. The inner top wall of the fixed frame 11 is hinged with a first protective steel plate net 21, the bottom of the first protective steel plate net 21 is hinged with a second protective steel plate net 22, and the bottom of the second protective steel plate net 22 is hinged with a baffle 23. The inner side wall of the fixed frame 11 is symmetrically provided with two slide grooves 24, and three pulleys 25 are symmetrically installed on both sides of the baffle 23. The pulleys 25 are slidably connected to the inner side wall of the slide groove 24.

[0025] In one embodiment, the front and rear surfaces of the fixing frame 11 are fixedly connected to a first fixing plate 12, and a fixing bolt 13 is installed on one side of the first fixing plate 12. One end of the fixing bolt 13 passes through the first fixing plate 12, and the outer side wall of the fixing bolt 13 is threadedly connected to the first fixing plate 12; through the setting of the fixing bolt 13, a mounting hole corresponding to the fixing bolt 13 is opened on the wall to be installed, the fixing bolt 13 is inserted into the first fixing plate 12, and then inserted into the mounting hole opened on the wall to fix the position of the fixing frame 11.

[0026] In one embodiment, two second fixing plates 26 are symmetrically fixedly connected to the lower surface of the baffle 23, and threaded through holes 27 are provided on the front and rear surfaces of the fixing frame 11 and one side of the second fixing plate 26. The inner side walls of the threaded through holes 27 are threadedly connected with threaded rods 28. Through the setting of the threaded rods 28, after the first protective steel plate mesh 21 and the second protective steel plate mesh 22 are turned up, the threaded through holes 27 provided on the second fixing plate 26 correspond to the positions of the threaded through holes 27 provided on the fixing frame 11, and then the threaded rods 28 are rotated to insert the threaded through holes 27 located in the threaded through holes 27 on the second fixing plate 26 into the threaded through holes 27 on the fixing frame 11, thereby fixing the position of the baffle 23 and fixing the positions of the first protective steel plate mesh 21 and the second protective steel plate mesh 22.

[0027] In one embodiment, two grooves 29 are symmetrically provided on the inner bottom wall of the fixed frame 11; through the setting of the grooves 29, when the first protective steel plate mesh 21 and the second protective steel plate mesh 22 are not flipped up, the baffle 23 is fitted with the bottom of the fixed frame 11, and the second fixing plate 26 and the threaded rod 28 on the baffle 23 are placed in the grooves 29 for storage.

[0028] In one embodiment, one end of the threaded rod 28 is fixedly connected to a knob 3, and two handles 4 are fixedly connected to both sides of the baffle 23; the setting of the knob 3 makes it convenient to rotate the threaded rod 28, and the setting of the handle 4 makes it convenient to pull the baffle 23 to move.

[0029] In one embodiment, a U-shaped plate 14 is fixedly connected to one side of the fixed frame 11; through the setting of the U-shaped plate 14, the U-shaped plate 14 is made of a transparent acrylic plate material, and the warning sign is inserted between the U-shaped plate 14 and the fixed frame 11 to fix the position of the warning sign, making it convenient to display the warning sign.

[0030] When the utility model is in operation: first, a mounting hole corresponding to the fixing bolt 13 is opened on the wall to be installed, and the fixing bolt 13 is inserted into the first fixing plate 12, and then inserted into the mounting hole opened on the wall to fix the position of the fixing frame 11. When the first protective steel plate mesh 21 and the second protective steel plate mesh 22 need to be flipped up, one hand holds the handle 4 and pulls it upward, and the other hand pushes the first protective steel plate mesh 21 and the second protective steel plate mesh 22 to assist the first protective steel plate mesh 21 and the second protective steel plate mesh 22 to fold and flip up. The baffle 23 cooperates with the pulley 25 to slide in the slide groove 24, limiting the movement trajectory of the baffle 23 so that the baffle 23 can only move up and down in the fixing frame 11, and the first protective steel plate mesh 21 and the second protective steel plate mesh 22 are flipped up. After the steel plate mesh 21 and the second protective steel plate mesh 22 are flipped up, the threaded through hole 27 opened on the second fixing plate 26 corresponds to the position of the threaded through hole 27 opened on the fixing frame 11, and then the threaded rod 28 is rotated, and the threaded rod 28 located in the threaded through hole 27 on the second fixing plate 26 is inserted into the threaded through hole 27 on the fixing frame 11, thereby fixing the position of the baffle 23, and fixing the position of the first protective steel plate mesh 21 and the second protective steel plate mesh 22. When the first protective steel plate mesh 21 and the second protective steel plate mesh 22 need to be lowered, the threaded rod 28 is turned out from the threaded through hole 27 on the fixing frame 11, the fixation of the baffle 23 is released, and the first protective steel plate mesh 21 and the second protective steel plate mesh 22 are lowered.

[0031] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
