Description

Technical Field

[0001] The utility model relates to the field of safe operation, in particular to a high-hanging, low-use five-point safety belt capable of accurately identifying a hook state. Background Art

[0002] Chinese utility model patent No. 202323136874.3 discloses a high-hanging, low-use five-point safety belt with a safety reminder function. During high-altitude operations, if the operator does not correctly hang the safety belt hook at a high place, an alarm will be issued in time to remind the operator to correctly hang the safety belt hook at a high place, thereby reducing the safety hazards existing during high-altitude operations. However, even if the hook of the above patent is hung low, due to the gravity of the hook and the length of the rope, the hook will naturally move downward, that is, the bend of the hook will still press against the corresponding component, and its moving contact and fixed contact will also be closed. The MCU of the reminder device detects that the hook is correctly hung high through the closed state of the moving contact and the fixed contact, but the hook is actually not hung correctly, which causes a recognition error, that is, the alarm will not be issued even if the hook is hung low.

[0003] In summary, in order to overcome the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a high-hanging, low-use five-point safety belt that can accurately identify the hook state.

[0029] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0030] like Figure 1 and 2 As shown, a high-hanging, low-use five-point safety belt that accurately identifies the hook status comprises a wearable body 1, a safety rope 2, and a hook 3. The wearable body 1 is fixedly strapped to the wearer's body, and the hook 3 is connected to the wearable body 1 via the safety rope 2. The utility model also includes a trigger mechanism and a tension spring 4. The trigger mechanism is mounted on the wearable body 1, and the ends of the tension spring 4 are connected to the hook and the trigger mechanism, respectively. When the hook is not hung high relative to the wearer, the hook, through the tension spring 4, causes the trigger mechanism to sound an alarm.

[0031] The trigger mechanism includes a fixed plate 5, a turntable 6, a fixed block 7 and a reminder device. The fixed plate 5 is made of non-metallic material and is fixed to the wearable body and corresponds to a position on the back of the operator near the shoulder. The turntable 6 and the fixed block 7 are both made of metal. The turntable 6 is rotatably mounted on the fixed plate 5. A metal conductive portion 8 protruding outward and having an arc structure is provided at the bottom of the turntable 6. The top of the turntable 6 is connected to the tension spring 4. The fixed block 7 is fixed to the fixed plate 5 and corresponds to a position directly below the conductive portion 8. The fixed block 7 is in contact with the conductive portion 8. The fixed block 7 is a structure that matches the conductive portion 8. After the turntable 6 rotates a preset angle, the conductive portion 8 is disengaged from the fixed block 7. A leaf spring is installed on the side of the fixed block 7 close to the turntable 6. The fixed block 7 is in contact with the conductive portion 8 through the leaf spring. The reminder device is fixed on the wearable body and corresponds to the position of the operator's chest, and the reminder device is electrically connected to the turntable 6 and the fixed block 7 through a wire 9. When the hook is not hung at a high position relative to the operator, the hook drives the turntable 6 to rotate a preset angle through the tension spring 4 to disengage the conductive part 8 from the fixed block 7 and trigger the reminder device to sound an alarm. The reminder device includes a housing 10, an MCU, a battery, and a buzzer 11. The MCU and the battery are both located in the housing 10, and the battery is connected to the power supply end of the MCU through a power supply circuit. The buzzer 11 is installed on the side of the housing 10. The signal input end of the MCU is electrically connected to the turntable 6 and the fixed block 7 through the wire 9, and the command output end of the MCU is electrically connected to the buzzer 11.

[0032] A lug 12 is provided on the top of the rotating disk 6, connected to the tension spring 4 and disposed opposite the conductive portion 8. A stopper is provided on the fixed plate 5 to prevent the lug 12 from contacting the fixed block 7 after the rotating disk 6 rotates. Preferably, the stopper includes two limiting rods 13, each of which is fixed to the fixed plate 5 and corresponds to a position on both sides of the fixed block 7.

[0033] like Figure 3-5 As shown, due to the configuration of the conductive portion 8, under the action of gravity of the conductive portion 8, the conductive portion 8 is naturally at the lowest point of the turntable 6. When the hook 3 is hung directly above the operator, the lug 12 is at the top of the turntable 6 under the action of the tension spring 4. At this time, the conductive portion 8 is in contact with the fixed block 7 through the leaf spring and conducts. The MCU detects the conduction signal of the wire 9 and recognizes that the hook 3 is in the "high hanging" state. It does not issue a start command to the buzzer 11, that is, no alarm is sounded. In addition, the center of the circle of the conductive portion 8 is concentric with the rotation center of the turntable 6, and the central angle of the conductive portion 8 is 60°. Therefore, after the turntable 6 rotates 60°, the conductive portion 8 is separated from the fixed block 7. Therefore, when the hook 3 is hung directly above the operator and swings to both sides within a 60° angle range, the conductive portion 8 can be in contact with the fixed block 7 through the leaf spring and conduct. Because when the hook 3 is hung directly above the operator and swings to both sides within a 60° angle range, it is still in a "high hanging" state relative to the operator. Similarly, when the hook 3 swings within the above range, the MCU can still recognize that the hook 3 is in a "high hanging" state and will not issue an alarm.

[0034] like Figure 6 and 7 As shown, when the hook 3 is hung directly above the operator and swings to both sides beyond the 60° angle, the turntable 6 rotates synchronously at an angle greater than 60°. Since the central angle of the conductive portion 8 is 60°, after the turntable 6 rotates at an angle greater than 60°, the fixed block 7 is separated from the conductive portion 8, the MCU cannot detect the conductive signal of the wire 9 and recognizes that the hook 3 is in the "low hanging" state, and it sends a start command to the buzzer 11, that is, it issues an alarm to remind the operator to hang the hook 3 in the correct position. When the rotating disk 6 continues to rotate to a large enough angle, the lug 12 on it will contact the fixed block 7. Therefore, a limit rod 13 is designed. When the lug 12 is about to contact the fixed block 7, the limit rod 13 limits the turntable 6 from continuing to rotate, to prevent the turntable 6 from rotating at an angle exceeding 60° and the lug 12 from contacting the fixed block 7, causing the MCU to mistakenly recognize that the hook 3 is in the "high hanging" state.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
