[0011] Furthermore, the seat belt locking device also includes a fixing structure, which is disposed on the rotating shaft and located in the receiving cavity. The fixing structure includes a first connecting plate, a second connecting plate, and a third connecting plate. The second connecting plate is connected between the first connecting plate and the third connecting plate. The first connecting plate is connected to the rotating shaft. The third connecting plate is located outside the rotating shaft, and an insertion port is formed between the third connecting plate and the rotating shaft.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0032] like Figures 1 to 3 as well as Figure 9 As shown, in this embodiment, the seatbelt locking device includes: a main body 10, a rotating shaft 20, a clearance opening 30, a first ratchet structure 40, a first locking structure 50, and a spring structure 60. A receiving cavity 11 is provided on the main body 10. The rotating shaft 20 is rotatably mounted on the main body 10, with a portion of the rotating shaft 20 located within the receiving cavity 11. The clearance opening 30 is provided on the main body 10 and communicates with the receiving cavity 11. The seatbelt 1 passes through the clearance opening 30 into the receiving cavity 11 and connects to the rotating shaft 20. The first ratchet structure 40 is provided on the side wall of the receiving cavity 11 and is spaced apart from the seatbelt along the axial direction of the rotating shaft 20. The first locking structure 50 is disposed within the receiving cavity 11. The first locking structure 50 includes a guide member 51, a first locking member 52, and an elastic member 53. The guide member 51 is connected to the rotating shaft 20, and its extension direction is perpendicular to the axis of the rotating shaft 20. The first locking member 52 is movably disposed on the guide member 51. The elastic member 53 is disposed between the guide member 51 and the first locking member 52. The first locking member 52 has an extended locking state and a retracted unlocking state. The elastic member 53 applies an elastic force to the first locking member 52 to keep it in the retracted unlocking state. When the speed at which the rotating shaft 20 rotates in the first direction is greater than a preset value, the first locking member 52 switches from the retracted unlocking state to the extended locking state and engages with the first ratchet structure 40. The spring structure 60 is disposed within the receiving cavity 11 and connected to the rotating shaft 20. The spring structure 60 drives the rotating shaft 20 to rotate in a second direction and wraps the seat belt 1 around the rotating shaft 20, wherein the second direction is opposite to the first direction.

[0033] Using the technical solution of this embodiment, a receiving cavity 11 is provided on the main body 10, and a rotating shaft 20 is rotatably passed through the main body 10. The seat belt 1 passes through the clearance opening 30 into the receiving cavity 11 and is connected to the rotating shaft 20. A first ratchet structure 40 is provided on the side wall of the receiving cavity 11, and a first locking structure 50 includes a guide member 51, a first locking member 52, and an elastic member 53. The first locking member 52 is movably disposed on the guide member 51, and the elastic member 53 is located between the first locking member 52 and the guide member 51. The first locking member 52 has an extended locking state and a retracted unlocking state. The elastic member 53 applies an elastic force to the first locking member 52 to keep the first locking member 52 in the retracted unlocking state. When the speed of the rotating shaft in the first direction is greater than a preset value, the first locking member 52 switches from the retracted unlocking state to the extended locking state and cooperates with the first ratchet structure 40 to stop. The spring structure 60 drives the rotating shaft 20 to rotate in the second direction and wraps the seat belt 1 around the rotating shaft 20. Specifically, by setting the first ratchet structure 40 and the first locking structure 50, the seat belt 1 can be automatically locked when pulled quickly, preventing the seat belt 1 from over-stretching and ensuring user safety. Simultaneously, the spring structure 60 can automatically retract the seat belt 1 into the receiving cavity 11, improving ease of use. Therefore, the technical solution of this embodiment effectively solves the problem of seat belt locking devices in related technologies being prone to failure and causing safety accidents.

[0034] Specifically, this design allows the safety belt locking device to quickly lock the safety belt 1 in an emergency, preventing the user from being injured due to inertia. Simultaneously, it automatically retracts the safety belt 1 in non-emergency situations, improving both convenience and safety. It is particularly suitable for scenarios requiring frequent movement, such as high-altitude operations, rock climbing, pole climbing, power maintenance, construction, and outdoor exploration.

[0035] In practical applications, this design can significantly reduce safety accidents caused by excessively long safety belts or failure to lock them in time, providing immediate protection for workers. At the same time, the automatic retraction function of the spring structure 60 reduces the difficulty of using the safety belt 1, allowing it to automatically retract when not in use, avoiding dragging and tangling, and improving work efficiency.

[0036] like Figures 1 to 4 As shown, in this embodiment, the seatbelt locking device further includes a second ratchet structure 71 and a second locking member 72. The second ratchet structure 71 is disposed outside the main body 10 and connected to the rotating shaft 20. The second locking member 72 is rotatably disposed on the main body 10 and can cooperate with the second ratchet structure 71 to prevent the rotating shaft 20 from rotating in the second direction. The above-described configuration enables active locking. When the second locking member 72 locks the second ratchet structure 71, the spring structure 60 cannot drive the rotating shaft 20 to rotate, meaning the seatbelt 1 cannot retract at this time.

[0037] Specifically, by adding a second ratchet structure 71 and a second locking element 72, the locking performance of the safety belt locking device is further improved, ensuring that the safety belt 1 can be reliably fixed under any circumstances, providing users with more comprehensive safety protection. This design is particularly important in operations such as power line maintenance and tree trimming, where the safety belt 1 needs to be fixed in a certain position.

[0038] In actual operation, the second ratchet structure 71 and the second locking member 72 can effectively prevent the safety belt 1 from loosening unexpectedly when subjected to unexpected tension, ensuring the stability of the operator in a fixed position, reducing the difficulty of operation, and improving the safety and efficiency of operation.

[0039] like Figure 5 , Figure 6 as well as Figure 8 As shown, in this embodiment, the first locking member 52 is provided with a limiting groove 521, and the first ratchet structure 40 can be inserted into the limiting groove 521. The aforementioned provision of the limiting groove 521 can achieve better locking stability.

[0040] It should be noted that the design of the limiting groove 521 makes the cooperation between the first locking member 52 and the first ratchet structure 40 more stable, resulting in a better locking effect and effectively preventing the safety belt 1 from over-extending in an emergency, thus protecting the user from injury. In scenarios such as climbing and working at heights, this design can significantly improve the reaction speed and locking efficiency of the safety belt 1.

[0041] In actual operation, the cooperation between the limiting groove 521 and the first ratchet structure 40 makes the locking process of the safety belt 1 faster and smoother. Even in extreme cases, it can ensure that the safety belt 1 is locked in time, preventing the operator from being in danger due to the excessive extension of the safety belt 1, and improving the safety and reliability of high-altitude operations.

[0042] like Figure 5 , Figure 6 as well as Figure 8 As shown, in this embodiment, there are multiple first locking structures 50, which are spaced apart and arranged around the outer periphery of the rotating shaft 20. This arrangement improves the stability of the locking.

[0043] Specifically, the multiple first locking structures 50 not only increase the reliability of the seat belt locking device but also improve its impact resistance, ensuring the locking function of the seat belt 1 even under extreme conditions. In industrial operations, training, and other scenarios requiring high-intensity safety protection, this design provides a higher level of safety assurance.

[0044] In practical applications, the design of multiple first locking structures 50 enables the seat belt locking device to effectively disperse the impact force when subjected to an impact through the combined action of multiple locking points, reducing the force on a single component and improving the overall stability and durability. Especially in environments such as training and industrial high-altitude operations, this design can significantly improve safety standards, reduce potential risks, and protect the lives of workers.

[0045] like Figures 1 to 8 As shown, in this embodiment, the seatbelt locking device further includes a connecting block 73 connected to the rotating shaft 20. The first locking structure 50 is connected to the connecting block 73. The receiving cavity 11 includes a first mounting space 111 and a second mounting space 112, as well as a first partition 113 separating the first mounting space 111 and the second mounting space 112. The first mounting space 111 is used to accommodate the seatbelt 1, and the first locking structure 50 is located within the second mounting space 112. The connecting block 73 can stably connect multiple first locking structures 50 together.

[0046] Specifically, the design of the first partition 113 makes the internal structure layout of the seat belt locking device more rational, improves space utilization, and ensures the independence and stability of each component, facilitating maintenance and repair. In fields requiring compact design, such as personal protective equipment and emergency rescue equipment, this design can meet the needs of high-density integration.

[0047] In practice, the design of the connecting block and the first partition not only optimizes the internal space of the seat belt locking device, but also makes the installation and maintenance of each component more convenient, reduces maintenance costs, and increases the service life of the equipment.

[0048] In fields such as personal protective equipment and emergency rescue equipment, this compact and rational design can meet the needs of high-density integration. Especially for equipment that needs to be carried around, this design can significantly reduce the size and weight of the equipment and improve portability and flexibility.

[0049] like Figure 4 and Figure 6As shown, in this embodiment, the seat belt locking device further includes a cover 81 and a locking friction member 82. The top wall of the cover 81 is connected to the rotating shaft 20. A second ratchet structure 71 is disposed on the outer surface of the side wall of the cover 81, and a third ratchet structure 83 is disposed on the inner surface of the side wall of the cover 81. The locking friction member 82 is swayably disposed on the main body 10 and located inside the cover 81. When the cover 81 rotates, the third ratchet structure 83 can push the locking friction member 82 to swing so that the locking friction member 82 abuts against the rotating shaft 20. The above arrangement enables the rotating shaft 20 to rotate and drive the cover 81 to rotate when the seat belt 1 is pulled out. When the cover 81 rotates, it can push the locking friction member 82 through the third ratchet structure 83, so that the locking friction member 82 can abut against the rotating shaft 20, thereby reducing the rotation speed of the rotating shaft 20.

[0050] Specifically, the design of the cover 81 and the locking friction element 82 increases the locking layers of the seatbelt locking device, making the locking process smoother and more reliable. Meanwhile, the swing design of the locking friction element 82 can adapt to pulling at different speeds and forces, improving the locking sensitivity and response speed. In scenarios requiring high-sensitivity locking functions, such as sports training and high-altitude amusement facilities, this design provides a better user experience.

[0051] In practical applications, the combination of the cover 81 and the locking friction element 82 can ensure that the pulling of the safety belt 1 at different speeds and forces can be locked in a timely and effective manner, thus improving the adaptability and flexibility of the device.

[0052] In sports training, such as rock climbing and high jump, this design provides a highly customized locking experience, ensuring athletes receive appropriate safety protection at different training stages, improving training effectiveness and safety. In high-altitude amusement facilities, such as zip lines and roller coasters in large amusement parks, this design significantly enhances passenger safety, ensuring safety during the ride and increasing the attractiveness of the amusement facility and the visitor experience.

[0053] like Figure 6 and Figure 7 As shown, in this embodiment, the seat belt locking device further includes a fixing structure 84, which is disposed on the rotating shaft 20 and located within the receiving cavity 11. The fixing structure 84 includes a first connecting plate 841, a second connecting plate 842, and a third connecting plate 843. The second connecting plate 842 is connected between the first connecting plate 841 and the third connecting plate 843. The first connecting plate 841 is connected to the rotating shaft 20, and the third connecting plate 843 is located outside the rotating shaft 20, forming an insertion port between the third connecting plate 843 and the rotating shaft 20. The fixing structure 84 can effectively fix the end of the seat belt 1, thereby improving the connection stability between the seat belt 1 and the rotating shaft 20.

[0054] Specifically, the design of the fixing structure 84 not only enhances the connection stability between the rotating shaft 20 and the main body 10, but also provides additional locking points, making the safety belt 1 more secure in the locked state and less prone to accidental loosening. In scenarios where the locked state needs to be maintained for a long time, such as high-altitude work and rock climbing, this design can significantly improve the user's sense of security.

[0055] In practical use, the setting of the fixed structure 84 can ensure that the safety belt remains stable in the locked state for a long time, and can also effectively prevent loosening caused by vibration or external impact, providing continuous safety protection for workers, reducing the safety risks of long-term high-altitude work, and improving work efficiency and safety.

[0056] like Figure 6 and Figure 7 As shown, in this embodiment, a protrusion 21 is provided on the rotating shaft 20. The protrusion 21 is located inside the receiving cavity 11 and protrudes toward the third connecting plate 843. The protrusion 21 can form a tighter fit with the fixing structure 84, further enhancing the locking effect of the rotating shaft 20. Especially when subjected to a large impact force, it can effectively prevent the rotating shaft 20 from rotating accidentally, protecting the user's safety.

[0057] In actual rescue operations, the tight cooperation between the protrusion 21 and the fixing structure 84 ensures that the safety belt 1 can lock immediately when rescuers are subjected to significant impact or tension, preventing accidental disengagement or slippage, thus improving rescue efficiency and protecting the safety of rescuers. Especially in emergency situations such as firefighting, this design provides immediate protection for rescuers, reducing the risks and difficulties of rescue operations and increasing the success rate and safety of rescue operations.

[0058] like Figures 1 to 3 As shown, in this embodiment, the seatbelt locking device further includes a second locking structure 91, and the receiving cavity 11 further includes a third mounting space 114 and a second partition 115. The second partition 115 is located between the first mounting space 111 and the third mounting space 114. The second locking structure 91 and the spring structure 60 are both disposed within the third mounting space 114 and connected to the rotating shaft 20. The second locking structure 91 is located above the spring structure 60. The aforementioned second locking structure 91 provides an additional locking mechanism for the seatbelt locking device. Combined with the automatic retraction function of the spring structure 60, it can provide dual protection in emergency situations, ensuring that the locking and retraction process of the seatbelt 1 is more stable and reliable.

[0059] In fields requiring high safety standards, such as industrial safety and personal protective equipment, this design can meet more stringent safety requirements.

[0060] In practical applications, the combination of the second locking structure 91 and the spring structure 60 ensures that the safety belt 1 not only locks quickly in an emergency, but also retracts automatically, providing comprehensive safety protection for workers.

[0061] In industrial safety fields, such as high-altitude operations in chemical plants and lifting and transporting equipment in mines, this design can significantly improve the safety standards of workers, reduce operational risks, and increase work efficiency. In the field of personal protective equipment, such as outdoor activities like mountaineering and exploration, this design can provide more stable and reliable protection, ensuring safety in emergency situations and enhancing the recreational and safe aspects of outdoor activities.

[0062] According to another aspect of this application, a pole climbing safety harness device is provided, such as... Figure 10 As shown, the pole climbing safety belt device in this embodiment includes a safety belt locking device, which is the safety belt locking device described above.

[0063] The pole climbing safety belt device integrates all the advantages of the aforementioned safety belt locking devices. It can not only quickly lock the safety belt in an emergency to prevent users from being injured due to accidental falls, but also automatically retract the safety belt in non-emergency situations, improving the convenience and safety of use.

[0064] Specifically, this device is particularly suitable for scenarios that require frequent climbing, such as power maintenance, construction, and outdoor exploration. Examples include power workers working on high-voltage power towers, construction workers working on scaffolding, and outdoor adventurers being protected during rock climbing.

[0065] The widespread application of pole climbing safety belt devices will significantly improve the safety and efficiency of high-altitude operations, reduce operational risks, and protect the lives of workers.

[0066] In practice, the application of pole-climbing safety harnesses provides comprehensive safety protection for power workers, construction workers, and outdoor adventurers. It not only quickly locks the safety harness in emergencies to prevent accidental falls, but also automatically retracts the harness in non-emergency situations, reducing operational difficulty and improving work efficiency. Especially in power maintenance, this device effectively prevents accidents caused by improper operation or external factors when power workers are working on high-voltage towers, improving the safety and efficiency of power maintenance.

[0067] In construction, this device provides stable safety for workers on scaffolding, reducing the safety risks of working at heights and improving construction quality and efficiency. In outdoor adventure, it provides immediate safety protection for climbers, enhancing both safety and enjoyment. The widespread application of pole climbing safety harnesses will revolutionize high-altitude work and outdoor adventure activities, significantly raising safety standards for workers, reducing operational risks, increasing work efficiency, and providing more comprehensive and stable safety guarantees for industrial safety, personal protective equipment, and other fields.

[0068] Through the above design, the safety belt locking device and pole climbing safety belt device provided in this embodiment are not only more compact in structure and easier to operate, but also more comprehensive in function and more reliable in performance, effectively improving the safety and efficiency of users in various high-altitude operations and outdoor adventure activities.

[0069] Furthermore, this device can provide stable and efficient safety guarantees in fields such as industrial safety and personal protective equipment, and has broad application prospects and market potential.
