Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-4 This utility model provides a seat belt fastening detection device, including a buckle structure, an infrared transmitter 1, and a detection component;

[0027] Infrared transmitter 1 is installed at the interlocking point of the seat belt and is used to emit infrared signals and detect the fastening status of the seat belt hook;

[0028] The detection component, installed at the seat belt buckle, includes: an infrared receiver 2, which is connected to an infrared transmitter 1 and is used to receive infrared signals emitted from the infrared transmitter 1;

[0029] Infrared sensor 3, which is connected to infrared transmitter 1, is used to sense changes in infrared signals.

[0030] Buzzer 4, which is connected to infrared transmitter 1, is used to issue an alarm when the seat belt hook is not fastened;

[0031] A power supply 5 is connected with the infrared emitter 1 to provide power for the detection assembly;

[0032] When the seat belt hook is not buckled, the infrared receiver 2 receives the infrared signal, the infrared sensor 3 senses the signal and makes the buzzer 4 alarm; when the seat belt hook is buckled correctly, the infrared is blocked, the infrared sensor 3 blocks the buzzer 4 circuit, and the buzzer 4 stops sounding.

[0033] The buckle structure comprises a clamping part 10 and a buckling part 11, which are detachably connected, and a first connecting part 12 and a second connecting part 13 are respectively arranged on the clamping part 10 and the buckling part 11, and the first connecting part 12 and the second connecting part 13 are used to connect the safety belt;

[0034] A first inner cavity and a second inner cavity are further arranged in the clamping part 10, two clamping holes 14 are arranged at both ends of the first inner cavity, and two communication grooves are further arranged between the first inner cavity and the second inner cavity;

[0035] A clamping piece 6 is fixedly arranged on the buckling part 11, and when the clamping part 10 and the buckling part 11 are in a combined state, the clamping piece 6 is located in the clamping hole 14 of the clamping part 10;

[0036] A positioning block 7 is fixedly arranged in the middle of the clamping piece 6;

[0037] Further, the infrared emitter 1 and the detection assembly are connected by wireless communication or wired connection for signal transmission.

[0038] Further, the infrared sensor 3 is an active infrared sensor;

[0039] It should be noted that the active infrared sensor itself emits infrared rays, just like the document mentioned, the infrared emitter at the interlocking position continuously emits infrared signals. When the seat belt hook is not buckled, the infrared is not blocked and normally propagates, and the infrared receiver at the lock catch receives it, thereby triggering the subsequent alarm action; once the hook is buckled on an object such as a steel pipe, the infrared is blocked, and the receiver cannot receive the signal, and the alarm will stop. The active infrared sensor is less affected by environmental light interference, has high detection accuracy, can actively control the detection range and intensity, and can work stably and accurately detect the state of the seat belt hook in a complex light construction site.

[0040] Further, the buzzer 4 is an adjustable volume and tone buzzer to adapt to different working environments;

[0043] The safety belt fastening detection device is provided with a modular detection unit; the infrared emitter 1 and the detection assembly are designed separately and connected through wireless communication (such as Bluetooth 5.0) to reduce wiring. The shell of the detection assembly is made of PC material, and the infrared sensor 3, the buzzer 4 and the rechargeable battery 5 are integrated inside and fixed to the lock catch through the clamping structure; the modular design facilitates maintenance and replacement of parts.

[0044] Further, the top and bottom of the positioning block 7 are uniformly distributed with a plurality of sawtooth blocks 8, and the top and bottom of the middle part of the clamping piece 6 are respectively provided with a plurality of sawtooth grooves 9 matched with the sawtooth blocks 8, for increasing the friction between the clamping part 10 and the buckling part 11 and further stabilizing the positioning connection of the two safety belts located at the first connecting part 12 and the second connecting part 13.

[0045] Further, the clamping piece 6 comprises a connecting frame 61 fixedly arranged on the outer wall of the buckling part 11.

[0046] A connecting rod 62 is connected to the two ends of the connecting frame 61, and a clamping block is further arranged on the end of the connecting rod 62 away from the second connecting part 13, which cooperates with the clamping hole 14 to connect the clamping part 10 and the buckling part 11.

[0047] Further, each connecting rod 62 is inclined, wherein the end of the connecting rod 62 close to the second connecting part 13 is inclined inward to provide a space for the overall buckling part 11 to move in the clamping part 10, and a resilient metal sheet is further arranged on the inner wall of the clamping part 10 in each space. When the clamping part 10 and the buckling part 11 are combined, the resilient metal sheet can provide a certain supporting effect with the clamping block, thereby ensuring the stable connection of the clamping part 10 and the buckling part 11. Therefore, the inclined connecting rod 62 and the resilient metal sheet together improve the safety performance and convenience of use of the safety belt buckle in normal use and abnormal conditions, and provide a better user experience for high-altitude workers.

[0048] The specific implementation process of the device is as follows: equipment installation: install the infrared emitter at the interlocking position of the conventional safety belt to ensure firm installation and not affect the normal wearing and use of the safety belt. During installation, pay attention to the emission direction of the infrared emitter to ensure that it can accurately emit infrared signals to the safety belt hook direction.

[0049] Install the detection assembly at the safety belt buckle, and ensure firm installation. Connect the lines between the infrared receiver, infrared sensor, buzzer and power supply to ensure normal signal transmission and power supply.

[0050] Device usage: When the operator wears the safety belt, the infrared emitter automatically starts the detection assembly.

[0051] During the operation, if the safety belt hook is not hung on a reliable object, the buzzer will issue a warning to remind the operator to correctly hang the safety belt. The operator should immediately stop the operation and hang the hook on a secure place, at which time the buzzer stops sounding.

[0052] Periodically check the working state of the device, including the power supply, infrared emission and reception, etc., to ensure that the device is always in normal working state.

[0053] Device maintenance: Keep the device clean to avoid dust, debris, etc. affecting the emission and reception of infrared rays.

At this time, the infrared sensor senses the signals, making the buzzer circuit connected, and the buzzer issues a warning. When the safety belt hook is correctly hung on a secure object such as a steel pipe, the infrared rays are blocked, the infrared receiver cannot receive the signals, the infrared sensor senses the signal change, and the buzzer circuit is blocked, so the buzzer stops sounding.

[0059] It is worth mentioning that the safety belt fastening detection device is used for emitting infrared signals and detecting the fastening state of the safety belt hook through the external induction controller 1 installed at the interlock of the safety belt; the detection assembly installed at the safety belt buckle, when the safety belt hook is not fastened, the infrared receiver 2 receives the infrared signals, the infrared sensor 3 senses the signals and makes the buzzer 4 alarm; when the safety belt hook is correctly fastened, the infrared is blocked, the infrared sensor 3 blocks the buzzer 4 circuit, and the buzzer 4 stops sounding, the detection device can detect the fastening state of the safety belt hook in real time, timely alarm when the hook is not fastened, reminding the operator to correctly fasten the safety belt, thereby reducing the risk of high-altitude falling accidents and protecting the life safety of the operator;

[0060] Real-time detection: the fastening state of the safety belt hook can be monitored in real time, and the situation of not being fastened or the hook falling off can be found in time, thereby providing timely safety reminders for the operator.

[0061] Automatic alarm: when the safety belt is not correctly fastened, the buzzer is automatically triggered to alarm without manual intervention, thereby improving the timeliness and reliability of safety protection.
