[0020] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0021] Example 1 Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6A fall arrester with an alarm function comprises an outer cavity 1, a middle plate 4 is installed in the middle of the outer cavity 1, a circular groove 2 and a barrel groove 3 are provided at the top of the outer cavity 1, a slide groove 5 is provided in the middle of the middle plate 4, a moving component 6 is provided on one side of the slide groove 5, the moving component 6 comprises an outer cylinder 61, an inner rod 62 is provided inside the outer cylinder 61, a spring 63 is connected between the outer cylinder 61 and the inner rod 62, a main shaft 64 is connected to the top of the inner rod 62, a connecting rod 65 is connected to one side of the main shaft 64, one end of the connecting rod 65 is connected to a connecting plate 66, one side of the outer cylinder 61 is fixedly connected to a side wall of the middle plate 4, the connecting rod 65 is slidably connected to the inner wall of the slide groove 5, and an anti-fall assembly 7 is provided on the other side of the slide groove 5, The anti-fall assembly 7 includes a long plate 71, a plurality of slots 72 are evenly provided on both sides of the top of the long plate 71, a gear 1 73 is provided on both sides of the long plate 71, a gear 2 74 is provided on one side of the two gears 1 73, an eccentric wheel 75 is provided on the front of the gear 2 74, an eccentric groove 76 is provided in the middle of the eccentric wheel 75, and a plurality of snap teeth 77 are connected to the outer wall of the eccentric wheel 75, the bottom of the long plate 71 is fixedly connected to the front of the connecting plate 66, the backs of the two gears 1 73 and the gear 2 74 are connected to the middle plate 4, the gear 1 73 is meshed and connected to one side of the long plate 71, the gear 1 73 is meshed and connected to the corresponding gear 2 74, and the inner wall of the eccentric groove 76 is fixedly connected to the outer wall of the short rod 78. During indoor rock climbing, the rock climber needs to wear the device on the back of the upper limb of the body, and the top and bottom of the outer cavity 1 are provided with circular grooves 2, and these two channels allow the safety rope to pass through them smoothly. During normal rock climbing, the safety rope slides slowly between the two rolling rods inside the device, ensuring the climber's freedom of movement while also providing the necessary safety protection. Once the climber accidentally loses control and faces an emergency situation of falling rapidly, the main shaft 64 in the device will trigger the protection mechanism due to weightlessness. The inner rod 62, which is closely connected to the main shaft 64, then rises rapidly inside the outer cylinder 61, and this action drives the eccentric wheel 75 and the long board 71 to move upward synchronously. The slots 72 on both sides of the specially designed long board 71 are tightly meshed with gear 1 73. As the slots 72 rise, they push gear 1 73 to rotate, and then drive gear 2 74 meshed with it to rotate synchronously. Due to the ingenious connection between the inner wall of the eccentric slot 76 and the outer wall of the short rod 78, the synchronous rotation of the eccentric wheel 75 and gear 2 74 is ensured. The two eccentric wheels 75 are moved closer to each other and turned upwards, tightly clamping the safety rope, thereby achieving instant locking between the fall arrester and the safety rope, effectively preventing the climber from falling further and avoiding possible serious accidents.

[0022] It is worth mentioning that after the climber regains stability, if he needs to continue climbing, he needs to move the fall arrester upward relative to the safety rope through a specific operation. During this process, the latching teeth 77 connected to the side wall of the eccentric wheel 75 will flip downward to release the grip on the safety rope, and the long board 71 will return to its original position, reopening a safe climbing channel for the climber.

[0023] Preferably, an alarm assembly 8 is provided at the top of the anti-fall assembly 7, and the alarm assembly 8 includes an electrode sheet 1 81 and a prevention groove 82, a battery 83 is provided at the bottom of the electrode sheet 1 81, a cover plate 84 is provided between the electrode sheet 1 81 and the battery 83, a square groove 85 is provided in the middle of the cover plate 84, and an electrode sheet 2 86 is connected to the inner wall of the square groove 85, a spotlight 87 and an alarm bell 88 are provided at the top of the electrode sheet 1 81, one side of the electrode sheet 1 81 is fixedly connected to the front of the cover plate 84, the prevention groove 82 is provided in the middle of the top of the long plate 71, the battery 83 is installed inside the prevention groove 82, and the cover plate 84 is connected to the top of the long plate 71 by snapping. The bottom end of the spotlight 87 is connected to the top of the middle plate 4, and the bottom end of the alarm assembly 8 is connected to the bottom end of the outer cavity 1. When the climber accidentally falls, the anti-fall device quickly activates the protection mechanism, which not only makes the anti-fall device and the safety rope relatively still instantly, but also triggers a series of emergency warning measures. During this process, as the long board 71 moves upward, the electrode sheet 2 86 on its top precisely fits with the electrode sheet 1 81. This fitting action activates the power stored in the battery 83, and quickly transmits the power to the two emergency devices, the spotlight 87 and the alarm bell 88. After receiving the power, the spotlight 87 immediately projects a dazzling light upward, forming a strong visual warning to ensure that the surrounding people can quickly detect the abnormality. At the same time, the alarm bell 88 uses the absorbed power to emit a high-decibel alarm sound, which penetrates the noisy environment, attracts the immediate attention of the staff, and prompts them to respond quickly and implement rescue operations.

[0024] In addition, if the climber is still able to continue climbing in an emergency and separates the electrode sheet 1 81 from the electrode sheet 2 86, the strong light of the spotlight 87 and the alarm sound of the alarm bell 88 will automatically stop to avoid unnecessary interference. However, if the climber is unable to continue and needs outside assistance, the staff will rush to the scene in time according to the continuous alarm signal and carry out effective rescue work to ensure the safety of the climber.

[0025] Preferably, a fixing assembly 9 is provided on the front of the outer cavity 1, and the fixing assembly 9 includes a cushion 91. Two long straps 92 are provided on the front of the cushion 91. The back of the long strap 92 is connected to the cushion 91 through a positioning strap 93. A reinforcing strap 94 is connected between the two positioning straps 93. The front of one of the long straps 92 is connected to a fixing strap 1 95, and the front of the other long strap 92 is connected to a fixing strap 2 96. The front and back of the outer cavity 1 are both rotatably connected to a rotating cover 10, and the back of the cushion 91 is connected to the front of one of the rotating covers 10. The two ends of the long strap 92 are respectively connected to the top and bottom of the outer cavity 1, and the back of the fixing strap 1 95 is connected to a Velcro sub-surface, and the front of the fixing strap 2 96 is connected to a Velcro mother surface. When the climbers wear the fall arrester, a highly humanized design scheme is adopted. They first naturally extend their hands and legs into the spacious space of the long straps 92 on both sides to ensure that the middle of the body fits tightly to the fall arrester body, and at the same time, the limbs flexibly pass through the two long straps 92 to achieve preliminary fixation. The specially designed reinforcement belt 94 partially fits the waist and back of the climber, providing a stable support point. The fixing belt 1 95 and the fixing belt 2 96 are waist-encircling belts. They cleverly go around the waist of the climber and fit each other to form a closed-loop system that is both stable and comfortable. This wearing method not only achieves a close connection between the climber and the fall arrester, effectively improving the safety performance, but also significantly reduces the sense of physical restraint that may be caused by traditional equipment. It allows climbers to enjoy safety while maintaining a high degree of flexibility and freedom of operation, making it easier for them to perform difficult climbing actions or deal with emergencies.
