Description

Technical Field

[0001] This invention relates to the field of rock climbing training technology, specifically to a centrifugal self-locking fall braking device for rock climbing training. Background Technology

[0002] As a popular extreme sport, rock climbing relies heavily on professional and reliable fall arrestors for its core safety features. The basic function of these devices is to instantly lock the safety rope in the event of a fall, effectively stopping the descent and protecting the climber's safety. An ideal fall arrestor should operate smoothly and without interference during normal climbing and rope deployment, while providing instantaneous and reliable braking in the event of a fall.

[0003] Most rock climbing braking devices on the market rely on sensing the rope's motion state for their triggering mechanism. However, during climbing, normal rapid rope pulling and releasing actions and the initial stage of a fall sometimes exhibit very similar characteristics in terms of rope speed and acceleration. This places extremely high demands on the braking device's recognition and judgment capabilities. Existing technologies, in order to ensure safety, often require a compromise between a sensitive trigger threshold and a smooth user experience.

[0004] This design compromise has led to a long-standing technical challenge: if the braking trigger mechanism of the device is calibrated to be too sensitive, while it ensures a rapid response to falls, it is prone to false locking, or "false locking," during the climber's large or rapid normal movements. Frequent false locking severely disrupts the climbing rhythm and affects the climbing experience. Conversely, if the trigger sensitivity is reduced to avoid false locking, the device may not respond promptly when a real fall occurs, resulting in an excessively long descent before locking. This not only increases the climber's psychological fear but also amplifies the impact, reducing the effectiveness of the protection. Current technology struggles to simultaneously meet the requirements of high response speed and avoiding false locking, which has become a key bottleneck restricting the improvement of the reliability of climbing protection devices.

[0005] Therefore, this invention proposes a centrifugal self-locking fall braking device for rock climbing training to overcome the shortcomings of the prior art. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a centrifugal self-locking fall protection device for rock climbing training, which solves the problems of existing fall protection devices being prone to accidental locking, large fall braking impact, and easy shaking and jamming during normal rope retrieval and release, resulting in insufficient protection reliability.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a centrifugal self-locking fall braking device for rock climbing training, comprising a support shell for support and protection, an inner groove inside the support shell, a rotating roller rotatably connected to the center of the inner groove, multiple connecting plates fixedly connected to the outer circumference of the rotating roller, a rotating wheel fixedly connected to the outer side of the connecting plates, an arc-shaped groove on the outer side of the rotating wheel, multiple centrifugal ejection components installed inside the rotating roller for fixing the rotating wheel to rotate in the opposite direction at high speed, a connecting frame fixedly connected to the left side of the support shell, an insert ring fixedly connected to the left side of the connecting frame, connecting discs fixedly connected to the upper and lower sides of the rotating roller through the outside of the support shell, one-way damping components installed on the upper and lower sides of the support shell for self-locking stability, a thumb support sleeve fixedly connected to the front end of the support shell, and a handle frame fixedly connected to the right rear end of the support shell.

[0008] Preferably, the unidirectional damping assembly includes mounting circular frames fixed on the upper and lower sides of the supporting housing, the outer side of the connecting plate is located in the middle of the inner side of the mounting circular frame, a torsion spring is fixedly connected to the outer side of the connecting plate, and a mounting ring is fixedly connected to the outer side of the torsion spring.

[0009] Preferably, the unidirectional damping assembly further includes a connecting circular frame fixed inside the mounting circular frame, and a plurality of unidirectional traction blocks are fixedly connected around the outer circumference of the mounting ring. The connecting circular frame has a slot inside that is adapted to the plurality of unidirectional traction blocks.

[0010] Preferably, a rotary damping shaft is fixedly connected to the outer side of the connecting plate, and the other end of the rotary damping shaft is fixedly connected to the inner side of the mounting frame.

[0011] Preferably, the centrifugal ejection assembly includes a plurality of centrifugal sliders that slide around the inside of the rotating roller. A fixing plate is fixedly connected to the outer side of the centrifugal slider, and a positioning rod is fixedly connected to the outer side of the fixing plate. The inner side of the centrifugal slider is connected to the inside of the rotating roller through a plurality of tension springs.

[0012] Preferably, the centrifugal ejection assembly further includes multiple snap-fit ​​seats fixed on the upper and lower sides inside the inner groove. The number of snap-fit ​​seats is equal to that of the positioning rods. The snap-fit ​​seats are located on both sides of the connecting plate and do not contact each other. The outer sides of the positioning rods are adapted to the inner grooves of the snap-fit ​​seats.

[0013] Preferably, both sides of the centrifugal slider are fixedly connected to limit plates, and the outer sides of the limit plates are respectively slidably connected to the inside of the rotating roller.

[0014] Preferably, a safety rope is inserted inside the supporting shell, and the safety rope is nested inside the right side of the arc-shaped groove.

[0015] Preferably, a plurality of extrusion plates are fixedly connected around the inside of the arc-shaped groove, and the plurality of extrusion plates are attached to the inner side of the safety rope.

[0016] Preferably, a protective sleeve is fixedly connected to the right side of the supporting shell to limit the upper safety rope from jumping around.

[0017] This invention provides a centrifugal self-locking fall braking device for rock climbing training. It has the following beneficial effects:

[0018] 1. This invention utilizes the centrifugal force generated during a fall to drive a positioning rod to achieve mechanical locking, which, in conjunction with the inner pressing arc plate of the rotating wheel, tightens the safety rope to achieve braking and locking. Simultaneously, the rotational speed of the rotating roller is constrained under normal conditions by the torsion spring and the rotational damping shaft. The rotational speed is limited during normal climbing rope retrieval and release, preventing the centrifugal slider from accidentally popping out. Only under the high-speed rotation caused by a fall can sufficient centrifugal force be generated to trigger self-locking, solving the problems of accidental locking and untimely response that are common in traditional rock climbing braking devices, thus improving the reliability of fall protection.

[0019] 2. By setting up a unidirectional damping component, the components work together to provide unidirectional damping buffer at the moment of fall locking, effectively reducing the instantaneous impact force of the fall on the device and the human body, avoiding the situation of rope overload and violent impact on personnel caused by rigid locking; it can also suppress sudden speed changes during normal climbing and rope retrieval, making the safety rope retrieval process smoother and reducing shaking and instantaneous jamming.

[0020] 3. In this invention, the centrifugal ejection self-locking mechanism and the one-way damping buffer mechanism are integrated into the support shell. The interlocking structure facilitates rope threading, the gripping parts are convenient for manual operation, and the protective sleeve can restrain the safety rope to prevent rope jumping or derailment. The whole device has a compact structure, is easy to carry and use, and takes into account both fall braking protection and the convenience of daily training operation, making it suitable for various working conditions in rock climbing training.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0029] Example:

[0030] Reference Figures 1-6A centrifugal self-locking fall braking device for rock climbing training includes a support shell 1 for support and protection. An inner groove 13 is formed inside the support shell 1. A rotating roller 9 is rotatably connected to the center of the inner groove 13. Multiple connecting plates 12 are fixedly connected to the outer circumference of the rotating roller 9. A rotating wheel 8 is fixedly connected to the outer side of the connecting plates 12. An arc-shaped groove 17 is formed on the outer side of the rotating wheel 8. Multiple centrifugal ejection components are installed inside the rotating roller 9 to achieve high-speed reverse rotation of the rotating wheel 8. A connecting frame 2 is fixedly connected to the left side of the support shell 1. A through-ring 3 is fixedly connected to the left side of the connecting frame 2. Connecting discs 10 are fixedly connected to the upper and lower sides of the rotating roller 9, penetrating the outside of the support shell 1. One-way damping components are installed on the upper and lower sides of the support shell 1 to achieve self-locking stability. A thumb support sleeve 4 is fixedly connected to the front end of the support shell 1. A handle frame 5 is fixedly connected to the right rear end of the support shell 1. The centrifugal ejection components include... The centrifugal ejection assembly includes multiple centrifugal sliders 15 that slide around the inside of the rotating roller 9. A fixing plate 18 is fixedly connected to the outside of the centrifugal slider 15, and a positioning rod 19 is fixedly connected to the outside of the fixing plate 18. The inside of the centrifugal slider 15 is connected to the inside of the rotating roller 9 through multiple tension springs 20. The centrifugal ejection assembly also includes multiple buckle seats 11 fixed on the upper and lower sides inside the inner groove 13. The number of buckle seats 11 is equal to the number of positioning rods 19. The buckle seats 11 are located on both sides of the connecting plate 12 and do not contact each other. The outer sides of the positioning rods 19 are adapted to the inner grooves of the buckle seats 11. Limiting plates 14 are fixedly connected to both sides of the centrifugal slider 15. The outer sides of the limiting plates 14 are respectively slidably connected to the inside of the rotating roller 9. A safety rope is inserted inside the support shell 1. The safety rope is nested inside the right side of the arc groove 17. Multiple extrusion arc plates 16 are fixedly connected around the inside of the arc groove 17. The multiple extrusion arc plates 16 are attached to the inside of the safety rope.

[0031] When a climber falls, the safety rope, subjected to the weight of the fall, rapidly pulls the rotating wheel 8, causing the rotating roller 9 to rotate at high speed in the opposite direction. Inside the rotating roller 9, the centrifugal slider 15, under centrifugal force, overcomes the spring tension of the tension spring 20 and slides outward. Simultaneously, the centrifugal slider 15 causes the fixing plate 18 and the positioning rod 19 to pop outward, allowing the positioning rod 19 to engage with the groove of the buckle seat 11, thus circumferentially limiting the rotating roller 9 and preventing it from continuing to rotate. At the same time, the compression plate 16 on the inner arc groove 17 of the rotating wheel 8 presses the safety rope as the wheel rotates. The mechanical locking mechanism, combined with the frictional force generated by the compression, clamps the safety rope, thus completing centrifugal self-locking braking at the moment of fall, effectively preventing the climber from falling further. The torsion spring 24 and the rotational damping shaft 25 can limit the rotation speed of the rotating roller 9 under normal conditions. During normal climbing and rope retrieval, the rotation speed of the rotating roller 9 is constrained, and the centrifugal slider 15 cannot obtain sufficient centrifugal force to pop out. Only the high-speed rotation generated by a fall can produce enough centrifugal force to trigger the locking action.

[0032] Reference Figures 1-6 The one-way damping assembly includes mounting round frames 6 fixed on the upper and lower sides of the support shell 1. The outer side of the connecting plate 10 is located in the middle of the inner side of the mounting round frame 6. A torsion spring 24 is fixedly connected to the outer side of the connecting plate 10. A mounting ring 22 is fixedly connected to the outer side of the torsion spring 24. The one-way damping assembly also includes a connecting round frame 21 fixed inside the mounting round frame 6. Multiple one-way traction blocks 23 are fixedly connected around the outer side of the mounting ring 22. The interior of the connecting round frame 21 has slots that are adapted to the multiple one-way traction blocks 23. A rotation damping shaft 25 is fixedly connected to the outer side of the connecting plate 10. The other end of the rotation damping shaft 25 is fixedly connected to the inner side of the mounting round frame 6. A protective sleeve 7 is fixedly connected to the right side of the support shell 1 to limit the upper safety rope from jumping around.

[0033] Under normal operating conditions, the torsion spring 24 and the rotary damping shaft 25 limit the rotation speed of the rotating roller 9. During normal climbing and rope retrieval operations, the rotation speed of the rotating roller 9 is constrained, and the centrifugal slider 15 cannot obtain sufficient centrifugal force to eject outward. Only when a fall causes high-speed rotation can sufficient centrifugal force be generated to trigger the locking action. During the high-speed rotation of the rotating roller 9 driven by the fall, the connecting discs 10 at both ends of the rotating roller 9 rotate synchronously, driving the mounting ring 22 and the one-way traction block 23 to rotate together. The one-way traction block 23 cooperates with the internal slot of the connecting frame 21 and generates one-way damping resistance under the synergistic action of the torsion spring 24 and the rotary damping shaft 25, buffering the rotation process of the rotating roller 9, thereby weakening the impact vibration brought by the fall. Once the fall danger is eliminated and the overall rotation speed decreases, the tension spring 20 pulls the centrifugal slider 15 to reset, the positioning rod 19 exits the slot of the buckle seat 11, the device is unlocked, and the safety rope can be released and retrieved normally. During the rope release and retrieval process, the one-way damping component continues to function to ensure the rope moves smoothly and prevent abnormal situations such as shaking or momentary jamming of the device.

[0034] Working principle section:

[0035] The working principle of this embodiment is as follows: When a climber falls, the safety rope quickly pulls the rotating wheel, causing the rotating roller to rotate in the opposite direction at high speed. The centrifugal slider inside the rotating roller slides outward due to centrifugal force overcoming the tension of the spring. The centrifugal slider drives the fixing plate and positioning rod to pop outward, causing the positioning rod to engage in the groove of the buckle seat, restricting the rotating roller from continuing to rotate. At the same time, the extrusion plate on the arc groove on the inner side of the rotating wheel presses the safety rope, using mechanical locking combined with extrusion friction to lock the safety rope, realizing centrifugal self-locking braking at the moment of fall and preventing the person from continuing to fall. The torsion spring and the rotational damping shaft can limit the rotation speed of the rotating roller under normal conditions. During normal climbing and rope winding, the rotation speed of the rotating roller is constrained, and the centrifugal slider cannot obtain enough centrifugal force to pop out. Only the high-speed rotation generated by the fall can generate enough centrifugal force to trigger the locking action.

[0036] During the high-speed rotation of the rotating roller as it falls, the connecting discs at both ends of the rotating roller rotate synchronously, causing the mounting ring and the one-way traction block to rotate together. Under the combined action of the groove inside the connecting frame and the torsion spring and the rotational damping shaft, the one-way traction block generates one-way damping resistance, which buffers the rotation of the rotating roller and weakens the impact vibration at the moment of fall. When the fall is stopped and the speed decreases, the tension spring pulls the centrifugal slider to reset, the positioning rod disengages from the buckle seat, the device unlocks, and the safety rope can be released and retrieved normally. The one-way damping component still plays the role of smoothly releasing and retrieving the rope and preventing the device from shaking or momentarily jamming.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
