[0032] like Figures 1 to 3 as well as Fig. 9 As shown, in this embodiment, the seat belt locking device includes: a main body 10, a rotating shaft 20, an escape opening 30, a first ratchet structure 40, a first locking structure 50 and a spring structure 60. A receiving chamber 11 is provided on the main body 10. The rotating shaft 20 is rotatably arranged on the main body 10, and a part of the rotating shaft 20 is located in the receiving chamber 11. The escape opening 30 is arranged on the main body 10 and communicates with the receiving chamber 11, and the seat belt 1 passes through the escape opening 30 into the receiving chamber 11 and is connected to the rotating shaft 20. The first ratchet structure 40 is arranged on the side wall of the receiving chamber 11 and is spaced apart from the seat belt in the axial direction of the rotating shaft 20. The first locking structure 50 is arranged in the accommodating 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. The extending direction of the guide member 51 is perpendicular to the axis of the rotating shaft 20. The first locking member 52 is movably arranged on the guide member 51. The elastic member 53 is arranged 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 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 20 rotating 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 clockwork structure 60 is arranged in the accommodating cavity 11 and connected to the rotating shaft 20. The clockwork structure 60 drives the rotating shaft 20 to rotate in the second direction and winds the safety belt 1 around the rotating shaft 20. The second direction is opposite to the first direction.

[0033] The technical solution of this embodiment is applied, the main body 10 is provided with a receiving chamber 11, the rotating shaft 20 is rotatably arranged on the main body 10, and the safety belt 1 is inserted into the receiving chamber 11 from the avoidance opening 30 and connected to the rotating shaft 20. The first ratchet structure 40 is arranged on the side wall of the receiving chamber 11, and the 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 arranged 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 rotating 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 stopper; the clockwork structure 60 drives the rotating shaft 20 to rotate in the second direction and winds the safety belt 1 around the rotating shaft 20. Specifically, by providing the first ratchet structure 40 and the first locking structure 50, the safety belt 1 can be automatically locked when it is pulled quickly, preventing the safety belt 1 from being overstretched, and ensuring the safety of the user. At the same time, the setting of the clockwork structure 60 can automatically retract the safety belt 1 into the accommodating cavity 11, thereby improving the convenience of use. Therefore, the technical solution of this embodiment effectively solves the problem that the safety belt locking device in the related art is prone to failure and safety accidents occur.

[0034] Specifically, this design enables the safety belt locking device to quickly lock the safety belt 1 in an emergency to prevent the user from being in danger due to inertia, and can automatically retract the safety belt 1 in a non-emergency state, thereby improving the convenience and safety of use. It is particularly suitable for scenes that require frequent movement, such as aerial work, rock climbing, pole climbing, etc., such as power maintenance, construction, outdoor adventures, etc.

[0035] In practical applications, this design can significantly reduce safety accidents caused by the safety belt being too long or not locked in time, and provide immediate protection for the operators. At the same time, the automatic recovery function of the clockwork structure 60 reduces the difficulty of using the safety belt 1, so that it can automatically retract when not in use, avoiding drag and entanglement, and improving work efficiency.

[0036] like Figures 1 to 4 As shown, in this embodiment, the safety belt 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. The second locking member 72 can cooperate with the second ratchet structure 71 to prevent the rotating shaft 20 from rotating in the second direction. The above arrangement can achieve active locking. When the second locking member 72 locks the second ratchet structure 71, the clockwork structure 60 cannot drive the rotating shaft 20 to rotate, that is, the safety belt 1 cannot be retracted at this time.

[0037] Specifically, by adding the second ratchet structure 71 and the second locking member 72, the locking performance of the safety belt locking device is further improved, ensuring that the safety belt 1 can be reliably fixed in any case, providing more comprehensive safety protection for the user. This design is particularly important in operations such as power line maintenance and tree pruning that require the safety belt 1 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 accidentally loosening when subjected to unexpected tension, thereby ensuring the stability of the operator in a fixed position, reducing the difficulty of operation, and improving operation safety and efficiency.

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

[0040] It should be noted that the design of the limit groove 521 makes the cooperation between the first locking member 52 and the first ratchet structure 40 more stable, and the locking effect is better, which effectively prevents the safety belt 1 from overstretching in an emergency and protects the user from injury. In scenes such as climbing and high-altitude operations, this design can significantly improve the reaction speed and locking efficiency of the safety belt 1.

[0041] In actual operation, the cooperation between the limit 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 to prevent workers from being in danger due to excessive stretching of the safety belt 1, thereby improving the safety and reliability of aerial operations.

[0042] like Figure 5 , Figure 6 as well as Figure 8 As shown, in this embodiment, there are a plurality of first locking structures 50, and the plurality of first locking structures 50 are disposed at intervals around the outer circumference of the rotating shaft 20. The above arrangement can improve the stability of locking.

[0043] Specifically, the provision of multiple first locking structures 50 not only increases the reliability of the safety belt locking device, but also improves its ability to withstand impact, and can ensure the locking function of the safety belt 1 even under extreme conditions. In industrial operations, training and other scenarios that require high-intensity safety protection, this design can provide a higher level of safety protection.

[0044] In actual applications, the design of multiple first locking structures 50 can enable the seat belt locking device to effectively disperse the impact force through the joint action of multiple locking points when it is impacted, reduce the stress on a single component, and improve the overall stability and durability. Especially in training, industrial high-altitude operations and other environments, this design can significantly improve safety standards, reduce potential risks, and protect the lives of operators.

[0045] like Figures 1 to 8 As shown, in this embodiment, the safety belt locking device further includes a connecting block 73, the connecting block 73 is connected to the rotating shaft 20, the first locking structure 50 is connected to the connecting block 73, the accommodating chamber 11 includes a first installation space 111 and a second installation space 112 and a first partition 113 separating the first installation space 111 and the second installation space 112, the first installation space 111 is used to accommodate the safety belt 1, and the first locking structure 50 is located in the second installation 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 reasonable, improves space utilization, and ensures the independence and stability of each component, making maintenance and repair easier. In the fields of personal protective equipment and emergency rescue equipment that require compact design, this design can meet the needs of high-density integration.

[0047] In actual operation, 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 various components more convenient, reduces maintenance costs, and increases the service life of the equipment.

[0048] In the fields of personal protective equipment, emergency rescue equipment, etc., this compact and reasonable 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 also includes a cover body 81 and a locking friction member 82, the top wall of the cover body 81 is connected to the rotating shaft 20, the second ratchet structure 71 is arranged on the outer surface of the side wall of the cover body 81, and the third ratchet structure 83 is arranged on the inner surface of the side wall of the cover body 81. The locking friction member 82 is swingably arranged on the main body 10 and located inside the cover body 81. When the cover body 81 rotates, the third ratchet structure 83 can push the locking friction member 82 to swing so that the locking friction member 82 abuts and cooperates with the rotating shaft 20. The above arrangement can make the rotating shaft 20 rotate and drive the cover body 81 to rotate when the seat belt 1 is pulled out. When the cover body 81 rotates, the locking friction member 82 can be pushed by the third ratchet structure 83, and the locking friction member 82 can abut and cooperate with the rotating shaft 20, thereby realizing the reduction of the rotation speed of the rotating shaft 20.

[0050] Specifically, the arrangement of the cover 81 and the locking friction member 82 increases the locking level of the seat belt locking device, making the locking process smoother and more reliable. At the same time, the swinging design of the locking friction member 82 can adapt to pulling at different speeds and strengths, thereby improving the sensitivity and response speed of the locking. In scenarios such as sports training and high-altitude entertainment facilities that require a highly sensitive locking function, this design can provide a better user experience.

[0051] In practical applications, the combination of the cover 81 and the locking friction member 82 can ensure that the safety belt 1 can be promptly and effectively locked when pulled at different speeds and forces, thereby improving the adaptability and flexibility of the device.

[0052] In sports training, such as rock climbing and high-altitude jumping, this design can provide a highly customized locking experience, ensuring that athletes can get proper safety protection at different training stages, improving training effectiveness and safety. In high-altitude entertainment facilities, such as zip lines and roller coasters in large amusement parks, this design can significantly enhance passengers' sense of security, ensure safety during the ride, and improve the attractiveness of entertainment facilities and the experience of tourists.

[0053] like Figure 6 and Figure 7 As shown, in this embodiment, the seat belt locking device also includes a fixing structure 84, which is arranged on the rotating shaft 20 and located in the accommodating cavity 11, and 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, the third connecting plate 843 is located outside the rotating shaft 20, and an insertion port is formed 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 making the connection stability between the seat belt 1 and the rotating shaft 20 better.

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

[0055] In actual use, the setting of the fixed structure 84 can ensure that the safety belt not only remains stable in a locked state for a long time, but also effectively prevents loosening caused by vibration or external force impact, providing continuous safety protection for operators, reducing the safety risks of long-term high-altitude operations, 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, and the protrusion 21 is located in the accommodating cavity 11 and protrudes toward the third connecting plate 843. The arrangement of 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, thereby protecting the safety of the user.

[0057] In actual rescue operations, the close cooperation between the protrusion 21 and the fixing structure 84 can ensure that when the rescuer is subjected to a large impact or tension, the safety belt 1 can be locked immediately to prevent the rescuer from accidentally unhooking or falling out of the hand, thereby improving the rescue efficiency and protecting the safety of the rescuer. Especially in emergency situations such as firefighting, this design can provide immediate protection for the rescuers, reduce the risk and difficulty of the rescue operation, and improve the success rate and safety of the rescue operation.

[0058] like Figures 1 to 3 As shown, in this embodiment, the seat belt locking device further includes a second locking structure 91, the accommodating chamber 11 further includes a third installation space 114 and a second partition 115, the second partition 115 is located between the first installation space 111 and the third installation space 114, the second locking structure 91 and the spring structure 60 are both arranged in the third installation space 114 and connected to the rotating shaft 20, and the second locking structure 91 is located above the spring structure 60. The above-mentioned second locking structure 91 provides an additional locking mechanism for the seat belt locking device, which, combined with the automatic recovery function of the spring structure 60, can provide double protection in an emergency, ensuring that the locking and recovery process of the seat belt 1 is more stable and reliable.

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

[0060] In practical applications, the combination of the second locking structure 91 and the clockwork structure 60 can ensure that the safety belt 1 is not only quickly locked in an emergency, but also automatically retracted, thereby providing comprehensive safety protection for the operator.

[0061] In the field of industrial safety, such as high-altitude operations in chemical plants and lifting and transportation in mines, this design can significantly improve the safety standards of operators, reduce operational risks, and improve operational efficiency. In the field of personal protective equipment, such as outdoor activities such as mountaineering and exploration, this design can provide more stable and reliable protection, ensure safety in emergency situations, and improve the entertainment and safety of outdoor activities.

[0062] According to another aspect of the present application, a climbing pole safety belt device is provided, such as Fig.10 As shown, the pole climbing safety belt device of this embodiment includes a safety belt locking device, and the safety belt locking device is the safety belt locking device mentioned above.

[0063] The climbing pole safety belt device integrates all the advantages of the above-mentioned safety belt locking devices. It can not only quickly lock the safety belt in an emergency to prevent the user from being injured due to accidental falls, but also automatically retract the safety belt in non-emergency situations, thereby 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, outdoor exploration, etc., such as power workers working on high-voltage towers, construction workers on scaffolding, and protecting outdoor explorers during rock climbing.

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

[0066] In actual operation, the application of pole climbing safety belt devices will provide comprehensive safety protection for power workers, construction workers and outdoor explorers. Not only can the safety belt be quickly locked in an emergency to prevent accidental falls, but it can also automatically retract the safety belt in non-emergency situations, reducing the difficulty of operation and improving work efficiency. Especially in power maintenance, this device can effectively prevent safety 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 can provide stable safety protection for construction workers on scaffolding, reduce the safety risks of high-altitude operations, and improve construction quality and efficiency. In outdoor adventures, this device can provide immediate safety protection for explorers during rock climbing, improving the safety and fun of adventures. The widespread use of climbing pole safety belt devices will bring revolutionary changes to high-altitude operations and outdoor adventure activities, significantly improve the safety standards of operators, reduce operational risks, improve operational efficiency, and bring more comprehensive and stable safety protection to industrial safety, personal protective equipment and other fields.

[0068] Through the above design, the safety belt locking device and climbing pole 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] Moreover, in the fields of industrial safety and personal protective equipment, this device can provide stable and efficient safety protection, and has broad application prospects and market potential.

[0070] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0071] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below".
