[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 - Figure 5This utility model provides an embodiment of an integrated pull strap adjuster for a child safety seat alarm function, comprising an upper shell 1. The front end of the upper shell 1 has a first slot 2 for the pull strap to pass through, and a second slot 3 located below the first slot 2. The rear end of the upper shell 1 has a third slot 4. A support main board 5 is housed within the upper shell 1. A hook-shaped extension plate 6 is integrally formed at the lower end of the support main board 5. A through hole is provided at the connection between the support main board 5 and the extension plate 6. A spring plate 8 is elastically provided on the extension plate 6, which can dynamically close the hook area under elastic force. A visible indicator 9 is provided on the front end face of the support main board 5 and located within the second slot 3. The indicator 9 is configured to display green (representing a safe state) and red (representing a dangerous state). The system allows for switching between different states. The rear end of the main board 5 is equipped with an alarm component corresponding to the third slot 4. The alarm component activates when the indicator 9 turns red and deactivates when the indicator 9 remains green. The main board 5 also has an operation button 10 for releasing the pull strap lock. The upper shell 1 serves as an external protection and support structure. The first slot 2 allows the pull strap to pass through, enabling it to smoothly enter the regulator. The second slot 3, located below the first slot 2, provides a position for the installation and display of the indicator 9, allowing operators to easily view its status. The third slot 4 corresponds to the alarm component and is used for its installation. The main board 5 provides a mounting base for other components, and its lower end is integrally formed in a hook shape. The extended plate 6, shaped like a hook, together with the supporting main plate 5, forms a structure for fixing and adjusting the pull strap. The hook-shaped design allows it to easily hook onto the car's mounting bracket. The spring plate 8 dynamically closes the hook area under elastic force. When fixed, the spring plate 8 automatically closes the hook area under elastic force to prevent the pull strap from accidentally coming off, providing safety protection. When unlocked, pressing the spring plate 8 separates it from the mounting bracket. The indicator 9 is visible and can switch between green (representing a safe state) and red (representing a dangerous state). The indicator 9 is connected to the alarm component via sensors and detection circuits. When the pull strap is abnormally tensile, the indicator 9 displays red, indicating that the child safety seat is in a dangerous state. The alarm component and... The indicator 9 is connected and can respond to changes in its state. When indicator 9 turns red, it indicates that the child safety seat is in a dangerous state, and the alarm component will immediately activate the alarm function. The alarm component uses an audible alarm to attract the operator's attention by emitting a loud alarm sound, reminding them to take timely measures to eliminate the safety hazard. When indicator 9 remains green, it indicates that the child safety seat is in a safe state, and the alarm component will deactivate the alarm and stop emitting alarm signals to avoid unnecessary interference. The operation button 10 is used to release the pull strap lock. When it is necessary to adjust or remove the pull strap, the operator presses the operation button 10, which triggers the unlocking mechanism inside the adjuster, allowing the pull strap to move and enabling the pull strap to be unlocked.

[0022] Please see Figure 5 In this embodiment, the alarm component includes a main body 11 connected to the supporting motherboard 5. A housing 12 is detachably connected to the main body 11. A sliding groove 13 is provided on the housing 12. A switch 14 adapted to the sliding groove 13 is installed on the main body 11. By controlling the movement of the switch 14, the alarm component can be turned on or off. The main body 11 is the core component of the alarm function. It is connected to the supporting motherboard 5 and provides an installation platform for the electronic components inside the alarm component (such as alarm circuit, sound module, signal processing module, etc.). It is responsible for receiving signals from the indicator 9. The housing 12 protects the internal components of the alarm component. The sliding groove 13 on the housing 12 is adapted to the switch 14 installed on the main body 11, providing a track for the movement of the switch 14. By controlling the movement of the switch 14 in the sliding groove 13, the connection state between the switch 14 and the internal circuit of the alarm component can be changed. When the switch 14 moves to a specific position, the alarm circuit is turned on, and the alarm function of the alarm component is activated. When the switch 14 moves to another position, the alarm circuit is turned off, and the alarm function is deactivated.

[0023] Please see Figure 2 - Figure 5In this embodiment, the inner wall of the upper shell 1 is symmetrically provided with vertical grooves 15 that are adapted to the side wall of the supporting main board 5. The contact surface of the operation button 10 is an arc-shaped structure, and the side end face of the arc-shaped structure is arrayed with through grooves 18. The upper shell 1 and the outer shell 12 are both provided with the same screw holes. The alarm component is fixedly installed to the upper shell 1 by fastening bolts. The lower end of the third slot 4 is symmetrically provided with a support plate 16 for supporting the alarm component. The support plate 16 is provided with a vertical plate 17 for limiting. The upper end of the third slot 4 is provided with a slot 20. The upper end of the outer shell 12 is provided with a wedge-shaped block 19 that is adapted to the slot 20. The wedge-shaped block 19 is connected to the slot 20. The vertical groove 15 provides precise guidance and positioning for the installation of the supporting main board 5. When installing the support motherboard 5, the vertical slot 15 guides the support motherboard 5 to be accurately inserted into the upper shell 1 along a specific direction, ensuring the accurate installation position of the support motherboard 5. The contact surface of the operation button 10 is designed with an arc-shaped structure. This design conforms to ergonomic principles and can better fit the shape of the operator's fingers, making it more comfortable and effortless for the operator to press the operation button 10. The through slots 18 arrayed on the side end face of the arc-shaped structure can reduce the weight of the operation button 10 and reduce material costs. The screw holes provide a connection structure for the alarm component to be fixedly installed to the upper shell 1 by fastening bolts. When installing the alarm component, place the alarm component in a suitable position, align the screw holes on the upper shell 1 and the outer shell 12, and then screw in the fastening bolts. Through the threaded connection between the bolts and the screw holes, the alarm component is firmly fixed to the upper shell 1. The receiving plate 16 provides bottom support for the alarm component, allowing the alarm component to be stably placed in the third slot 4. Inside, the vertical plate 17 can restrict the horizontal movement of the alarm component, preventing the alarm component from being horizontally displaced due to vibration or external force during the operation of the regulator, ensuring that the relative position between the alarm component and the third slot 4 is fixed, and ensuring that the alarm component can work normally. When installing the alarm component, the wedge-shaped block 19 is aligned with the slot 20, and a certain pressure is applied to insert the wedge-shaped block 19 into the slot 20. The special shape of the wedge-shaped block 19 allows it to gradually squeeze the inner wall of the slot 20 during insertion, producing a certain elastic deformation, thereby achieving a tight connection with the slot 20. This connection method between the slot 20 and the wedge-shaped block 19 can, on the one hand, quickly and conveniently fix the alarm component on the upper shell 1, improving installation efficiency; on the other hand, the tight fit between the wedge-shaped block 19 and the slot 20 can enhance the connection stability between the alarm component and the upper shell 1, preventing the alarm component from loosening in the vertical direction.

[0024] Working principle: First, the pull strap is passed through the first slot 2 of the upper shell 1, and the hook-shaped extension plate 6 at the lower end of the supporting main board 5 is installed in the fixed seat on the car. The spring plate 8 dynamically closes the hook area under the action of elastic force to ensure that the pull strap is stable and does not come out.

[0025] When the safety harness is abnormally tensioned, indicator 9 changes from green to red, indicating that the safety seat is in a dangerous state. At this time, the alarm component responds to the change in the state of indicator 9 and immediately activates the alarm function, emitting a loud alarm sound through the sound module to attract the operator's attention. After hearing the alarm sound, the operator should promptly check the state of indicator 9 and take measures to adjust the tension of the safety harness or check other parts of the safety seat to eliminate the safety hazard. When the safety hazard is eliminated and the safety harness returns to normal tension, indicator 9 changes from red back to green, and the alarm component then deactivates the alarm and stops emitting alarm signals.

[0026] If the pull belt needs to be adjusted, the operator presses the operation button 10. The operation button 10 triggers the unlocking mechanism inside the regulator, allowing the pull belt to move and complete the unlocking operation.

[0027] Through the above steps, by integrating the visual indicator 9 with the intelligent alarm component, the status of the child safety seat can be monitored and warned, thereby improving safety performance and enhancing protection. This enables operators to quickly identify dangers and take measures to eliminate hidden dangers in a timely manner, solving the problem that existing strap adjusters lack strap tension monitoring and warning mechanisms, which seriously threatens the safety of children riding in cars.
