[0029] See also Figures 1 to 5 In the above embodiment, the anti-fall device further comprises: a mounting plate 3. The mounting plate 3 is arranged on the outer wall of the building. Specifically, the mounting plate 3 is attached to the outer wall of the building, and the mounting plate 3 is connected to the outer wall of the building.

[0030] The mounting frame 1 is connected to the mounting plate 3 in an angle-adjustable manner, that is, the angle between the mounting frame 1 and the mounting plate 3 is adjustable.

[0031] The anti-fall device also includes: two positioning mechanisms 14 and two adjustment plates 4. The two adjustment plates 4 are arranged in parallel, that is, the two adjustment plates 4 are parallel. Each adjustment plate 4 is vertically arranged on the mounting plate 3, and each adjustment plate 4 is rotatably connected to the mounting frame 1, so that the mounting frame 1 and the mounting plate 3 can rotate freely. Preferably, the mounting frame 1 and the adjustment plate 4 are hingedly connected.

[0032] Specifically, a first hinge shaft 5 is disposed on a plate surface on one side of each adjustment plate 4 , and the first hinge shaft 5 is perpendicular to the adjustment plate 4 and parallel to the mounting plate 3 .

[0033] The mounting frame 1 is provided with a connecting plate 6 at a position corresponding to each first hinge shaft 5. Specifically, there are two connecting plates 6. The two connecting plates 6 are both provided on the side of the mounting frame 1 facing the mounting plate 3, and the two connecting plates 6 correspond to the two first hinge shafts 5 one by one. Each connecting plate 6 is provided with a first hinge hole 61. The two first hinge shafts 5 correspond to the first hinge holes 61 on the two connecting plates 6 one by one. Each first hinge shaft 5 can be rotatably inserted into the corresponding first hinge hole 61. The first hinge shaft 5 can rotate in the first hinge hole 61, so that the mounting frame 1 can rotate freely with the two adjustment plates 4, that is, the rotation between the mounting frame 1 and the mounting plate 3 is realized.

[0034] Preferably, two mounting posts 7 are arranged side by side on the mounting plate 3, each mounting post 7 is perpendicular to the mounting plate 3, the two mounting posts 7 are parallel, and the two mounting posts 7 are placed between the two adjustment plates 4. A second hinge shaft 8 is arranged horizontally between the two mounting posts 7, and the second hinge shaft 8 is parallel to the mounting plate 3. The first hinge shaft 5 on each adjustment plate 4 is arranged on a side of the adjustment plate 4 away from the corresponding mounting post 7. Specifically, the two mounting posts 7 and the second hinge shaft 8 are placed in the middle of the mounting plate 3, and the two first hinge shafts 5 extend outward.

[0035] The mounting frame 1 is provided with a hinge plate 9 at a position corresponding to the second hinge shaft 8 . Specifically, the hinge plate 9 is placed between the two connecting plates 6 . The hinge plate 9 is provided with a second hinge hole 91 . The second hinge shaft 8 is rotatably passed through the second hinge hole 91 .

[0036] The two positioning mechanisms 14 correspond to the two adjustment plates 4 one by one. Each positioning mechanism 14 is disposed on the corresponding adjustment plate 4 . Each positioning mechanism 14 is used to position the installation frame 1 when the installation frame 1 rotates to a desired angle.

[0037] Specifically, each adjustment plate 4 is provided with a plurality of insertion holes 41 at intervals, and each insertion hole 41 is distributed in an arc shape. Each insertion hole 41 runs through the thickness direction of the adjustment plate 4, and each insertion hole 41 is evenly distributed in an arc shape with the first hinge shaft 5 as the center. The number of insertion holes 41 on the two adjustment plates 4 is the same, and the arrangement positions of each insertion hole 41 on the two adjustment plates 4 correspond to each other.

[0038] Each connecting plate 6 is further provided with an adjusting screw hole 62 , the central axis of the adjusting screw hole 62 is parallel to the central axis of the first hinge hole 61 , and the adjusting screw hole 62 is closer to the center of the installation frame 1 than the first hinge hole 61 .

[0040] During specific use, the mounting frame 1 is rotated, and the hinged plate 9 on the mounting frame 1 is freely rotated along the second hinge axis 8 and the two connecting plates 6 are freely rotated along the corresponding first hinge axis 5, so that the mounting frame 1 is rotated relative to the mounting plate 3.

The two positioning bolts position the two connecting plates 6, that is, the position of the mounting frame 1 is positioned, so that the mounting frame 1 remains fixed in this position.

[0041] It can be seen that in this embodiment, the structure in which the angle between the mounting frame 1 and the mounting plate 3 can be adjusted is simple and easy to implement.

[0042] See also Figures 1 to 4 In each of the above embodiments, the buffer mechanism includes: at least one pair of magnets 10. Among them, each magnet 10 is arranged in sequence along the length direction of the housing body 2 (the length direction of the housing body 2 is the direction from the opening end to the bottom end opposite to the opening end), and the two magnets 10 in each pair are respectively arranged on the outer walls of the housing body 2 on the opposite sides, and the two magnets 10 in each pair are magnetically attracted to each other, and the two magnets 10 in each pair sandwich the housing body 2 in the middle after the magnetic attraction, so that the housing body 2 is in a flattened state. Specifically, each magnet 10 can be a strip-shaped soft magnet. In this way, after the falling person or object falls from the open end of the bag-shaped body 2 into the bag-shaped body 2, since the bag-shaped body 2 is in the shape of a bag, the bag-shaped body 2 itself has a certain buffering performance, and the arrangement of the magnet 10 makes the magnets 10 adsorbed together gradually expand in the process of the falling person or object falling to the bottom of the bag-shaped body 2. This expansion process is also a buffering process, that is, after the falling person or object falls into the bag-shaped body 2, it will not fall to the bottom of the bag-shaped body 2 instantly, but will first overcome the magnetic force of the magnet 10, so that the bag-shaped body 2 is gradually expanded. This process is a process with resistance, which can play a buffering role, thereby achieving buffering for the falling person or object.

[0043] The buffer mechanism also includes: at least one buffer component 11. Each buffer component 11 is connected to the bottom end of the housing body 2 opposite to the open end, and each buffer component 11 is detachably connected to the mounting frame 1. Each buffer component 11 is used to disconnect from the mounting frame 1 after a falling person or object falls into the housing body 2. Specifically, each buffer component 11 is arranged at intervals at the bottom end of the housing body 2. More specifically, each buffer component 11 is arranged between the bottom end of the housing body 2 and the two connecting plates 6.

[0044] In specific implementation, the number of buffer components 11 can be determined according to actual conditions, and this embodiment does not impose any restrictions on this. In this embodiment, there are two buffer components 11. The two buffer components 11 correspond to the two connecting plates 6 one by one, and each buffer component 11 is detachably connected to the corresponding connecting plate 6.

[0045] See also Figures 2 to 4 Each buffer assembly 11 includes a buffer rope 111 and a sphere 112. The bottom surface of the connecting plate 6 ( Figure 4A spherical groove is provided on the bottom of the housing 2, and the ball 112 is embedded in the groove, and the radial distance at the opening of the groove is smaller than the outer diameter of the ball 112. Specifically, the radial distance at the opening of the groove is smaller than the radial distance at the center of the groove, and the radial distance at the opening of the groove is smaller than the outer diameter of the ball 112, so that the opening of the groove can block the ball 112. The first end of the buffer rope 111 is connected to the bottom end of the housing 2, and the second end of the buffer rope 111 is connected to the ball 112.

[0046] In specific implementation, the radial distance at the opening of the groove and the outer diameter of the sphere 112 can be determined according to actual conditions to ensure that under normal circumstances, the sphere 112 is stably placed in the groove, and when a falling person or object falls into the pocket body 2, the sphere 112 can escape from the opening of the groove.

[0047] If the radial distance at the opening of the groove is smaller than the outer diameter of the sphere 112, the opening of the groove blocks the sphere 112. Although the sphere 112 is blocked from escaping from the opening of the groove, so that the sphere 112 is stably placed in the groove, when the weight of the falling person or object is heavy, the sphere 112 can be guaranteed to escape from the groove, so that the bottom end of the pocket body 2 is in a vertical state under the action of gravity, thereby cushioning and receiving the falling person or object; even if the weight of the falling person or object is light and the sphere 112 does not escape from the groove, the pocket body 2 can still receive, block and cushion the falling person or object.

[0048] In a specific implementation, a mounting body 13 is provided on the bottom surface of each connecting plate 6 , and a spherical groove is provided on the mounting body 13 .

[0049] In a normal state, the sphere 112 is placed in the groove, and the bottom of the bag body 2 is relatively fixed with the connecting plate 6 together with the sphere 112, so that the bag body 2 can be reliably arranged to prevent the bag body 2 from drifting randomly due to the wind. When a person or an object falls into the bag body 2, the person or the object suddenly pulls the buffer rope 111 as an external force, and the buffer rope 111 pulls the sphere 112 out of the groove, which plays a buffering role, so that the bottom end of the bag body 2 is in a vertical state under the action of gravity. In the process of falling people or objects falling to the bottom of the bag body 2, the magnets 10 adsorbed together gradually open up, which also plays a buffering role, achieving buffering of the falling people or objects.

[0050] Preferably, the pocket body 2 is a mesh bag or a cloth bag; and / or, the mounting plate 3 is connected to the building exterior wall via expansion bolts 12.

[0051] In summary, in the present embodiment, the open end of the bag body 2 is connected with the middle hollow part of the installation frame 1, and a falling person or object can fall into the bag body 2, and the bag body 2 receives and cushions the falling person or object. Compared with the anti-fall net in the prior art, the bag body 2 has a better cushioning effect, and the installation frame 1 is connected to the outer wall of the building at an adjustable angle, so that the angle of the installation frame 1 can be adjusted, that is, the inclination of the installation frame 1 can be adjusted, thereby effectively receiving the falling person or object, and the buffer mechanism is arranged on the bag body 2 to cushion the person or object falling into the bag body 2, further improving the cushioning effect, ensuring the safety of the falling person or object, and preventing the injury of the falling person or the damage of the falling object. The structure of the device is simple and easy to implement.
