[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1

[0037] Reference Figure 1-6 , which is the first embodiment of the present utility model, and provides an anti-falling mechanism, including a hook body 100, a swinging groove 101 is opened on the surface of the hook body 100; a closing plate 200, one end of which is equipped with a first rotating rod 201, and the closing plate 200 is rotatably connected to the inside of the swinging groove 101 through the first rotating rod 201; when in use, by pressing the closing plate 200, the closing plate 200 is rotated by the first rotating rod 201, thereby exposing the opening of the hook body 100 for placing objects. In addition, a spring is provided between the closing plate 200 and the hook body 100 for resetting the closing plate 200. Because this technology is relatively mature, it will not be described in detail in this solution.

[0038] The limiting component 300 includes a card slot 301 provided on the inner wall of the hook body 100, an insertion slot 302 provided on one side of the hook body 100, and a limiting rod 303 slidably connected to the inner cavity of the insertion slot 302. A limiting slot 304 is provided on one side of the closing plate 200. When the closing plate 200 contacts the inner wall of the hook body 100, the card slot 301 is provided to enable the closing plate 200 to be clamped in the card slot 301 for limitation. By inserting the limiting rod 303 into the limiting slot 304 through the insertion slot 302, the closing plate 200 and the hook body 100 can be limited to avoid loosening of the connection between the hook body 100 and the closing plate 200.

[0039] Among them, in specific use, the number of limit rods 303 is two, and the two limit rods 303 are symmetrically arranged on both sides of the insertion groove 302. The length value of the limit rod 303 is greater than half the depth value of the limit groove 304. The surface of the limit rod 303 is connected to the limit block, and the inner wall of the insertion groove 302 is provided with a limit slot. When the limit rod 303 slides in the insertion groove 302, the limit block slides synchronously in the limit slot, which can play a guiding and limiting role. When the limit block slides to the bottom end of the limit slot, the opposite ends of the two limit rods 303 contact each other.

[0040] Furthermore, it also includes a rotating component 400, which includes a rotating disk 401 installed on one side of the hook body 100, a first magnet 402 and a second magnet 403 installed on one side of the rotating disk 401, and a third magnet 404 installed on one end of the limiting rod 303. The opposite magnetic poles of the second magnet 403 and the third magnet 404 are magnetically identical, and the opposite magnetic poles of the first magnet 402 and the third magnet 404 are magnetically opposite. When in use, the second magnet 403 is aligned with the third magnet 404 at one end of the limiting rod 303, and the arrangement between the two The repulsive force can push the limiting rod 303 inserted into the insertion slot 302 into the limiting slot 304, completing the limiting between the hook body 100 and the closing plate 200. When the limiting needs to be released, the rotating disk 401 is rotated forward so that the second magnet 403 is away from the third magnet 404 and the first magnet 402 is close to the third magnet 404. The attraction between the first magnet 402 and the third magnet 404 can make the limiting rod 303 detach from the inside of the third magnet 404, thereby releasing the limiting between the hook body 100 and the closing plate 200.

[0041] Among them, a rotating shaft 401a is installed on one side of the rotating disk 401, and the rotating disk 401 is rotatably connected to the hook body 100 through the rotating shaft 401a. By setting the rotating shaft 401a, the rotating disk 401 can be rotated along the rotating shaft 401a; an arc-shaped groove 401b is opened on one side of the rotating disk 401, and the inner cavity of the arc-shaped groove 401b is slidably connected with a positioning block 401c, and the positioning block 401c is connected to the hook body 100. By setting the arc-shaped groove 401b and the positioning block 401c, the rotation angle of the rotating disk 401 can be limited, so that after the rotating disk 401 rotates a certain angle, the first magnet 402 is set opposite to the third magnet 404; the first magnet 402, the second magnet 403, the third magnet 404, the arc-shaped groove 401b and the positioning block 401c are all located on a circle with the axis of the rotating shaft 401a as the center.

[0042] Furthermore, it also includes a connecting component 600, which includes a connecting ring 601, a rotating pin 603 installed on the connecting ring 601, and a rotating groove 602 opened at the top of the hook body 100. The connecting ring 601 is rotatably connected to the inner wall of the rotating groove 602 through the rotating pin 603. By setting the connecting ring 601, it is convenient to hang or connect the hook body 100. By setting the rotating groove 602 and the rotating pin 603, the angle between the connecting ring 601 and the hook body 100 can be adjusted.

[0043] Operation process: When in use, by pressing the closing plate 200, the closing plate 200 rotates with the first rotating rod 201, thereby exposing the opening of the hook body 100 for placing an object. After the object is placed, the closing plate 200 is released. Under the action of the spring return force, the closing plate 200 can move in the opposite direction until it is engaged in the card slot 301. At this time, the rotating disk 401 is rotated so that the second magnet 403 is opposite to the position of the third magnet 404. The repulsive force between the second magnet 403 and the third magnet 404 The limiting rod 303 in the insertion slot 302 can be pushed and inserted into the limiting slot 304 to complete the limiting between the hook body 100 and the closing plate 200. When the limiting needs to be released, the rotating disk 401 is rotated again so that the second magnet 403 is away from the third magnet 404 and the first magnet 402 is close to the third magnet 404. Through the attraction between the first magnet 402 and the third magnet 404, the limiting rod 303 can be separated from the inside of the third magnet 404, and the limiting between the hook body 100 and the closing plate 200 is released.

[0044] Example 2

[0045] Reference Figures 1 to 8, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an anti-falling mechanism; it also includes a linkage component 500, which includes a gear 501 meshing with the rotating disk 401, a rotating plate 502 installed on one side of the gear 501, and a second rotating rod 503 installed on the other side of the gear 501. The second rotating rod 503 is arranged inside the hook body 100, wherein the number of gears 501 is two, and the two gears 501 are respectively installed on both sides of the second rotating rod 503. When in use, by rotating any one of the rotating plates 502, it drives the gear 501 connected thereto to rotate synchronously. Under the connection of the second rotating rod 503, the other gear 501 can be driven to rotate, so that the two rotating disks 401 can be driven to rotate at the same time, and then the two limit rods 303 can be driven at the same time.

[0046] Furthermore, a sleeve 504 is installed inside the hook body 100, and the second rotating rod 503 is rotatably connected to the inside of the sleeve 504. A torsion spring 505 is provided on the inner side of the second rotating rod 503 and the sleeve 504, and the two ends of the torsion spring 505 are respectively connected to the surface of the second rotating rod 503 and the inner wall of the sleeve 504, wherein the torsion spring 505 corresponds to the second magnet 403 and the third magnet 404 under normal conditions. The deformation force of the torsion spring 505 can prevent the gear 501 from rotating, and then prevent the rotating disk 401 from rotating, thereby ensuring the stability of the limiting rod 303 in limiting the position between the hook body 100 and the closing plate 200.

[0047] The rest of the structure is the same as that of Example 1.

[0048] When the gear 501 is in the reverse direction, the second magnet 403 and the third magnet 404 are engaged, and the limiting rod 303 is sucked out from the inner part of the limiting groove 304. When the closing plate 200 is engaged in the slot 301, the rotating plate 502 is released, and the torsion spring 505 is reset, so that the second rotating rod 503 can be rotated forward. Under the connection of the gear 501, the rotating plate 501 can be rotated in the reverse direction. At this time, the second magnet 403 corresponds to the third magnet 404. The repulsive force between the second magnet 403 and the third magnet 404 can make the limiting rod 303 inserted into the limiting groove 304, completing the limitation between the hook body 100 and the closing plate 200.

[0049] Example 3

[0050] Reference Figure 9, which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a protective device for climbing operations, including an anti-falling mechanism and a protective component 700. The protective component 700 includes a connecting ring 701 connected to the connecting ring 601, a connecting piece 702 rotatably connected to the connecting ring 701, a slider 703 connected to the connecting piece 702, and a slide rail 704 used in conjunction with the slider 703. The slide rail 704 is made of stainless steel. When in use, the slide rail 704 is installed on the outdoor ladder to be used in conjunction with the slider 703 for climbing operations. During the climbing process, the person wears a five-point safety belt and the slider 703 is hung on the chest safety belt. When the person climbs and moves, the slider 703 moves in conjunction with the slide rail 704. When an emergency event of falling from a height occurs, the slider 703 self-locks to prevent the person from falling.

[0051] Furthermore, a positioning plate 704a is welded on the slide rail 704, and a positioning groove 704b is provided on one side of the positioning plate 704a. By setting the positioning plate 704a and the positioning groove 704b, when the slide rail 704 is installed on the outdoor ladder, the slide rail 704 can be fixed to the outdoor ladder by bolts, iron wire or steel wire, and then the outdoor ladder and the slide rail 704 can be welded. By pre-fixing, measurement can be facilitated to avoid tilting during installation.

[0052] The rest of the structure is the same as that of Example 1 or 2.

[0053] Operation process: Install the slide rail 704 on the outdoor ladder and use it with the slider 703 to perform climbing operations. During the climbing process, the person wears a five-point safety belt and the slider 703 is hung on the chest safety belt. When the person climbs and moves, the slider 703 and the slide rail 704 move together. When an emergency event of falling from a height occurs, the slider 703 self-locks to prevent the person from falling.
