DETAILED DESCRIPTION

[0036] In order for those skilled in the art to better understand the present application, the present application will be further described in detail below in conjunction with specific embodiments and the accompanying drawings.

[0037] The terms used in the present application are those general terms currently widely used in the art in consideration of the functions about the present application, but these terms can be changed according to the intention of those skilled in the art, precedents, or new technology in the art. In addition, specific terms can be selected by the applicant, and in this case, the detailed meaning thereof will be described in the detailed description of the present application. Therefore, the terms used in the specification should not be understood as simple names, but based on the meaning of the terms and the overall description of the present application.

[0038] REFERENCE Figure 1The embodiment provides a closed type anti-falling safety belt, which comprises a left hook 1 and a right hook 3 connected with the left hook 1 through a safety rope 2; the left hook 1 and the right hook 3 are of the same structure and are mirror image arranged. The left / right hook 3 can be sequentially divided into a shell 11, an opening part connected with one side end of the shell 11 and a connecting part 18 connecting the opening part end with the other side end of the shell 11 from top to bottom. The shell 11 is of an arc structure, and a battery 13 is further arranged in the shell 11; a switch 14, a battery 13 charging hole and an electric quantity display screen 16 are arranged on the outer wall of the shell 11, and the switch 14 is electrically connected with the battery 13; the shell 11 can be made of insulating materials such as nylon, plastic and the like, preferably nylon material. The connecting part 18 is provided with a safety belt hanging hole 17 away from the bottom end of the shell 11, which is used for being connected with a safety belt and limiting the moving position of the safety belt.

[0039] With reference to Figure 2 The shell 11 of the right hook 3 is provided with a first wireless module 4, the lower side of the shell 11 of the right hook 3 is provided with a second contact piece 5, and the opening of the right hook 3 is provided with a second limiting piece 6.

[0040] With reference to Figure 3 The shell 11 of the left hook 1 is provided with a second wireless module 7, the lower side of the shell 11 of the left hook 1 is provided with a first contact piece 8, and the opening of the left hook 1 is provided with a first limiting piece 9.

[0041] It should be noted that the first / second limiting piece 6 is equivalent to the opening part described above; when the first / second contact piece 5 is in contact with the second / first wireless module 4, the opening part is pressed by an external force, so that the whole device has an opening, so that the hook can be separated from the safety hanging point; when the opening part loses the pressing of the external force and the first / second contact piece 5 is not in contact with the second / first wireless module 4, the opening part makes the whole device in a closed state, so that the hook cannot be separated from the safety hanging point.

[0042] The contact state of the second contact piece 5 and the first wireless module 4 can control the closing of the first limiting piece 9, and the contact state of the first contact piece 8 and the second wireless module 7 can control the closing of the second limiting piece 6.

[0043] In the prior art, one of the reasons for the frequent dangerous accidents of the staff in high-altitude displacement operation is the negligence of the staff; when one safety buckle is buckled on the safety hanging point, the other safety buckle is separated from the safety hanging point.

[0044] With reference to Figure 4 and Figure 5And the present application sets wireless module control and the abutment on the left and right hooks 3, so that when the left and right hooks 3 are not hung on the safe hanging point, they cannot be opened at the same time. The left and right hooks 3 cannot be opened at the same time, which means that when the left and right hooks 3 are used for high-altitude displacement operation, one of them must be hung on the safe hanging point and cannot be separated from the safe hanging point. This setting solves the problem that the existing safety belt cannot remind the worker whether the safety belt hook is securely connected during displacement operation, and the hooks of the two backup protection ropes can be opened at the same time, so that the worker loses the protection of the safety belt during high-altitude operation.

[0045] Specifically, during displacement operation, the left hook 1 and the right hook 3 are alternately hung on the safe hanging point; the first abutment 8 is pressed by the safe hanging point and triggers the second wireless module 7 to send a signal to control the second limiting part 6 to be in an open state; the second abutment 5 is pressed by the safe hanging point and triggers the first wireless module 4 to send a signal to control the first limiting part 9 to be in an open state.

[0046] In some embodiments, referring to Figure 2 and Figure 3 , the first limiting part 9 includes a first hook tongue piece 91 arranged at the end of the opening of the left hook 1 and a first tongue piece limiting block 92 rotatably connected to the other end of the opening of the left hook 1; the end of the first hook tongue piece 91 away from the first tongue piece limiting block 92 is connected to the end of the connecting part 18 through an elastic connecting part, which can be a connecting shaft with a torsional spring, a hinge with a spring, a spring, etc. This setting allows the first hook tongue piece 91 to rotate around the end point connected to the connecting part 18 when an external force presses the first hook tongue piece 91, and when the first hook tongue piece 91 rotates, the hook as a whole will open, allowing the hook to be separated from the safe hanging point through the opening. When there is no external force pressing the first hook tongue piece 91, the first hook tongue piece 91 will return to the initial state under the action of the elastic force of the elastic connecting part, at which time the hook as a whole is in a closed state, and the working principle of the second hook tongue piece 61 is the same as that of the first hook tongue piece 91.

[0047] The end of the first tongue piece limiting block 92 away from the first hook tongue piece 91 is electrically connected to the electromagnetic switch 1412, and the length of the end of the first tongue piece limiting block 92 extending out of the opening can control the opening and closing state of the first hook tongue piece 91.

[0048] Specifically, the second limiting part 6 includes a second hook tongue piece 61 arranged at the end of the opening of the right hook 3 and a second tongue piece limiting block 62 rotatably connected to the other end of the opening of the right hook 3;

[0049] The second tongue limiting block 62 is electrically connected with the electromagnetic switch 1412 at the end away from the second hook tongue 61, and the length of the end of the second tongue limiting block 62 extending out of the opening can control the opening and closing state of the second hook tongue 61.

[0050] It should be noted that, referring to Figure 4 and Figure 5 , the first / second tongue limiting block 62 is provided with a protruding part 63 at one end, and the first / second hook tongue 61 is provided with a plug-in slot at the end, the protruding part 63 can be inserted into the inner wall of the plug-in slot, and the other end of the first / second tongue limiting block 62 extends into the inner wall of the shell 11 and is connected with the electromagnetic switch 1412, the electromagnetic switch 1412 receives the first / second wireless module 7 to drive the first / second tongue limiting block 62 to displace upward or downward, when the first / second tongue limiting block 62 displaces upward, the plug-in slot at the end of the hook tongue is separated from the protruding part 63, at this time the hook tongue can rotate under the pressing force of the outside, when the first / second tongue limiting block 62 displaces downward, the protruding part 63 is inserted into the inner wall of the plug-in slot at the end of the hook tongue, at this time the hook is in a closed state.

[0051] Further, referring to Figure 2 , the first wireless module 4 includes a first transmitting module 41 and a second receiving module 42, and the second wireless module 7 includes a second transmitting module 71 and a first receiving module 72;

[0052] Referring to Figure 3 , the second receiving module 42 can receive the signal emitted by the first transmitting module 41 and control the length of the end of the second tongue limiting block 62 extending out of the opening through the electromagnetic switch 1412 according to the signal;

[0053] The first receiving module 72 can receive the signal emitted by the second transmitting module 71 and control the length of the end of the first tongue limiting block 92 extending out of the opening through the electromagnetic switch 1412 according to the signal.

[0054] When the electromagnetic switch 1412 receives the signal to control the first / second tongue limiting block 62 to displace upward or downward, the plug-in state of the tongue limiting block and the hook tongue can be controlled.

[0055] Further, the first / second abutting member 5 includes a sliding block 81 and a conductive element 82 arranged on the sliding block 81; that is, the first abutting member 8 and the second abutting member 5 are the same in structure.

[0056] When the sliding block 81 moves in the direction of the shell 11 under the extrusion force, the conductive element can be connected with the lithium battery 13 and the first wireless module 4 / second wireless module 7 at the same time.

[0057] Furthermore, the conductive element 82 includes a first conductive post 821 and a second conductive post 822 disposed on both sides of the end face of the slider 81, and a conductive block disposed on the inner wall of the slider 81. The first conductive post 821 and the second conductive post 822 pass through the side wall of the slider 81 and are connected to the conductive block. The slider 81 is made of insulating material.

[0058] Furthermore, the first transmitting module 41 is disposed between the first conductive post 821 and the second conductive post 822. One end of the first transmitting module 41 is connected to the housing 11, and the other end of the first transmitting module 41 is connected to the end face of the slider 81.

[0059] When slider 81 moves toward housing 11, it can simultaneously drive the first transmitting module 41 to move. When the first transmitting module 41 moves, it can send a signal to the first receiving module 72.

[0060] Furthermore, the second transmitting module 71 is disposed between the first conductive post 821 and the second conductive post 822. One end of the second transmitting module 71 is connected to the housing 11, and the other end of the second transmitting module 71 is connected to the end face of the slider 81.

[0061] When slider 81 moves toward housing 11, it can simultaneously drive the second transmitting module 71 to move. When the second transmitting module 71 moves, it can send a signal to the second receiving module 42.

[0062] Working principle: When performing high-altitude relocation operations, such as Figure 4 As shown, when the left hook 1 is suspended at the safety point, the slider 81 on the left hook 1 is in contact with the housing 11 under the action of gravity and tension, which triggers the second transmitting module 71 to transmit a signal to the second receiving module 42. When the second receiving module 42 inside the right hook 3 receives the signal, it controls the electromagnetic switch 1412 to lift the second tongue limit block 62. At this time, the second hook tongue 61 is in an openable state. At the same time, when the right hook 3 is not suspended at the point, the first hook tongue 91 of the left hook 1 is in a closed state and cannot be opened.

[0063] like Figure 5 As shown, when the right hook 3 is suspended at the safety point, the slider 81 on the right hook 3 is in contact with the housing 11 under the action of gravity and tension, thereby triggering the first transmitting module 41 to transmit a signal to the first receiving module 72. When the first receiving module 72 on the housing 11 of the left hook 1 receives the signal, it controls the electromagnetic switch 1412 to lift the first tongue limit block 92. At this time, the first hook tongue 91 is in an openable state. At the same time, when the left hook 1 is not suspended at the point, the second hook tongue 61 of the right hook 3 is in a closed state and cannot be opened.

[0064] It should finally be pointed out that the methods and devices described in detail above are only embodiments, which the person skilled in the art can modify in different ways, without departing from the scope of the present invention.
