DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0022] Please refer to Figure 1The present invention proposes an intelligent safety belt hook, comprising a main body 1, a first movable part 2, a second movable part 3, a first detection device 4 for detecting whether the hook is hung on a human body and detecting a direction of the hook, a second detection device 5 for detecting whether the hook is closed, and a monitoring device 6; the monitoring device 6 is arranged at one side of the main body 1; the first movable part 2 is movably connected to the main body 1 and the second movable part 3 respectively; the movable end of the first movable part 2 abuts against or moves away from the end of the main body 1, and drives the second movable part 3 to move; the first detection device 4 is arranged in the main body 1; the second detection device 5 is arranged on the monitoring device 6; the first movable part 2 is provided with a slide groove 201, and the second movable part is provided with a cylinder 301, and the cylinder 301 is movably arranged in the slide groove 201; the first movable part 2 drives the second movable part 3 to move along the slide groove 201, and abuts against or moves away from the second detection device 5.

[0023] In this embodiment, a main body 1, a first movable member 2, a second movable member 3, a first detection device 4 and a second detection device 5 are provided. The first movable member 2 is rotatably connected to the main body 1, and the closing and opening of the hook are achieved by rotating the first movable member 2. The first movable member 2 is movably connected to the second movable member 3, and the second movable member 3 can be driven to move by rotating the first movable member 2, so as to contact or move away from the second detection device 5, and whether the hook is closed can be detected.

[0024] When the hook is open, the second movable member 3 moves away from the second detection device 5, and then the hook switches from the open state to the closed state, and the second movable member 3 contacts the second detection device 5. At this time, the second detection device 5 can detect that the hook is closed. When the hook is hung on the human body, it will contact the first detection device 4. At this time, the first detection device 4 will generate an electrical signal, thereby knowing whether the hook is hung on the human body.

[0025] The monitoring device 6 can receive and transmit data from the first detection device 4 and the second detection device 5, so as to know whether the hook is hung on the human body and whether the hook is closed; thereby enabling the control background to monitor the operator's hook usage status.

[0026] Specifically, the first movable member 2 is provided with a slide groove 201, and the second movable member 3 is provided with a cylinder 301, and the cylinder 301 is slidably connected with the slide groove 201. The movement of the first movable member 2 drives the cylinder 301 to move along the slide groove 201, and makes the second movable member 3 contact or move away from the second detection device 5, so as to detect whether the hook is closed.

[0027] More specifically, the main body is made by forging technology and can meet industrial-grade tensile requirements.

[0028] In one embodiment, the first detection device 4 is provided with a plurality of first contact switches 401 , the main body 1 is provided with a stepped groove 101 , and the first contact switches 401 are respectively located in the stepped groove 101 .

[0029] Specifically, Figure 2 As shown, the main body 1 is provided with a stepped groove 101, and the first contact switches 401 are respectively located in the stepped groove 101. In a specific embodiment, three first contact switches 401 are provided, and are respectively horizontally arranged in the stepped groove 101 to form a three-stage induction. The direction of the hook can be detected, and the phenomenon of hanging upside down can be avoided. In a specific embodiment, after the rope is hung on the hook, the rope contacts the first contact switch 401 located on the leftmost side of the hook, and the hanging direction of the hook is leftward at this time.

[0030] Please refer to Figure 2 Each first contact switch 401 includes a contact member 402 and a first switch member. The contact member 402 is movably disposed in the step groove 101 to squeeze or move away from the first switch member; the first switch member is disposed toward the contact member 402.

[0031] In specific implementation: the first switch element and the second switch element 502 are connected, and both are touch switches. The first switch element is mounted on a PCB (Printed Circuit Board). After touching the contact element 402, the contact element 402 will be displaced and expand and contract in the step groove 101. At this time, the touch switch will be touched, and the touch switch will return an electrical signal of 0 or 1. Whether the hook is hung on the human body is determined based on whether the signal is recognized.

[0032] Specifically, when the contact piece is touched, the first switch piece is squeezed, and at this time, the first switch piece generates an electrical signal, and at this time, it can be known that the hook has been hung on the human body. Then it is determined which contact switch sends the signal, so as to determine the direction of the hook. If the contact piece is not touched, no electrical signal change will be generated, and at this time, the hook is not hung on the human body, and the data is transmitted to the monitoring device.

[0033] Please refer to Figure 2 and Figure 5 The stepped groove 101 includes a first plane 102, a second plane 103 and a fixing member 104. The contact members 402 are respectively located on the second plane 103 and are movably connected to the fixing members 104. The fixing members 104 are located on the first plane 102 and are fixedly connected to the main body 1. The first switch member is arranged on the fixing member 104 and is arranged corresponding to the contact member 402.

[0034] In specific implementation: the step groove 101 includes a first plane 102, that is, a plane with a higher horizontal position in the step groove 101, and a second plane 103 is a plane with a lower horizontal position. The contact members 402 are respectively arranged horizontally on the second plane 103, and the fixing member 104 is arranged horizontally on the first plane 102 and fixedly connected to the main body 1. In a specific embodiment, the fixing member 104 is provided with a through hole, and the main body 1 is provided with a threaded hole corresponding to the through hole, and the fixing member 104 is installed and removed by rotating the screw. After installation, the fixing member 104 has an activity space with the main body 1, and the contact members 402 are respectively located in the activity space and move to achieve contact or distance between the contact members 402 and the first switch member.

[0035] Specifically, the fixing member 104 is provided with slots for placing the PCB and the first switch member, and the PCB is placed thereon, and the first switch member is respectively arranged on the PCB. Moreover, the first contact switch 401 is made of a casting process, which is more precise, so as to improve the accuracy of the detection result.

[0036] Please refer to Figure 2-Figure 6 The fixing member 104 is provided with a plurality of mounting posts 105 , and the first plane 102 is provided with mounting holes 106 corresponding to the mounting posts 105 , and the mounting posts 105 pass through the mounting holes 106 respectively.

[0037] In specific implementation, when the fixing member 104 is installed, the mounting posts 105 need to be respectively installed in the mounting holes 106. The height of the mounting posts 105 is higher than the height of the mounting holes 106.

[0038] Please refer to Figure 2-Figure 6 The contact members 402 are respectively provided with at least two notches 404 , and the mounting posts 105 are disposed in the notches 404 .

[0039] In specific implementation, the mounting post 105 is respectively passed through the notch 404 of the contact 402 and the first plane 102 to obtain the mounting hole 106. In a specific embodiment, one contact 402 is provided with two notches 404, and the notches 404 are distributed on the left and right sides of the contact 402. Since the contact 402 is provided with the notches 404, after touching the contact 402, the contact 402 can move along the mounting post 105 and touch the first switch, generating a change in the electrical signal to know whether the hook is hung on the human body.

[0040] Please refer to Figure 2 The contact members 402 are respectively provided with first inclined surfaces 405. When the contact members 402 are displaced, the first inclined surfaces 405 press or move away from the first switch member.

[0041] In specific implementation: the contact member 402 is provided with a first inclined surface 405, which can be displaced after being touched, and gradually touch the first switch member, thereby avoiding collision and squeezing the first switch member, which can not only improve the service life, but also make the detection result more accurate, and avoid the situation where the contact member 402 cannot squeeze the first switch member after being located.

[0042] Please refer to Figure 8 The second detection device 5 includes a contact block 501 and a second switch member 502 , and the contact block 501 is in contact with or away from the second switch member 502 .

[0043] In specific implementation: the second switch 502 is arranged toward the abutment block 501, and whether the abutment block 501 is in contact with the second switch 502 is judged to detect whether the hook is closed. When the abutment block 501 is in contact with the second switch 502, the electrical signal will change from the original "0" to "1", and then the signal change data will be transmitted to the monitoring device 6, at which time, the hook closed data is obtained.

[0044] Specifically, after the hook is opened, the movement of the first movable member 2 will drive the movement of the second movable member 3, and the second movable member 3 will first move away from the abutment block 501. Then the hook is closed, the second movable member 3 will contact the abutment block 501 again, and the abutment block 501 will contact the second switch member 502. At this time, the electrical signal will change. After the electrical signal change data is sent to the monitoring device 6, it is determined that the hook is closed.

[0045] Please refer to Figure 8 The abutment block 501 is provided with a second inclined surface 503 and a contact surface 504. When the second movable member 3 abuts against the second inclined surface 503, the contact surface 504 contacts the second switch member 502; when the second movable member 3 is away from the second inclined surface 503, the contact surface 504 is away from the second switch member 502.

[0046] In specific implementation: when the second movable member 3 abuts against the abutment block 501 provided with the second inclined surface 503, it will gradually squeeze the abutment block 501 and push the abutment block 501 toward the second switch member 502, thereby lightly touching the second switch member 502, causing the second switch member 502 to generate an electrical signal change; when the second movable member 3 moves away from the second inclined surface 503, the abutment block 501 loses its force and moves away from the second switch member 502. At this time, the state of the second switch member 502 will switch from "1" to "0".

[0047] In one embodiment, a key device is included, and the key device is electrically connected to the monitoring device 6 .

[0048] In specific implementation: the key device includes a key module with a type matching key and a data cable, where type is an interface, and the type matching key can be TypeScript or other keys. Insert the data cable into an external laser detector or host to know the hook number currently in use. If the seat belt is equipped with two hooks, numbered 01 and 02, insert the data cable of hook 01 into the Type-C interface of the host of the seat belt. At this time, the host recognizes the type matching key and knows that the hook currently in use is hook 01.

[0049] Please refer to Figure 1 , Figure 5 and Fig. 9 The monitoring device 6 includes a shell 601, a working indicator light, a data transmission device, a start button 602, a height measuring component, a power supply device and a charging interface 603. The working indicator light, the start button 602 and the charging interface 603 are respectively arranged on the shell 601, and the data transmission device, the height measuring component and the power supply device are respectively arranged in the shell 601.

[0050] In specific implementation: the housing 601 can be made of plastic, and the working indicator light, the start button 602 and the charging interface 603 can be respectively arranged on the housing 601. After pressing the start button 602, the working indicator light will light up to indicate that the hook can be used normally. At the same time, the start button 602 can start the data transmission device, the height measuring device and the power supply device to operate. When the hook is not closed, the server can transmit instructions to the data transmission device to control the flashing of the working indicator light to remind the operator that the hook is not yet hung, so as to avoid the occurrence of safety accidents. The data transmission device can receive the detection data of the first detection device 4 and the second detection device 5, and transmit it to an external communication device or server via 2.4ghz wireless. The height measuring device is an altitude altimeter, which can measure the working height of the operator. The power supply device is a power supply battery, which can power the data transmission device, the working indicator light, the first detection device 4 and the second detection device 5. The charging interface 603 is arranged on one side of the housing 601, and an external data line can be connected to charge the power supply battery.

[0051] Please refer to Figure 7 , including a hanging member 8, which is arranged on one side of the monitoring device 6; the hanging member 8 is provided with a through groove 801 for wearing a safety belt.
