Description

Technical Field

[0001] This utility model relates to the field of descender technology, specifically a safe anti-panic descender. Background Technology

[0002] A descender is a safety device used in outdoor sports such as adventure training, mountaineering, extreme sports, and rescue to protect operators from being trapped. It is also called a "descending protector". A self-locking descender is a type of descender.

[0003] According to a self-locking descender disclosed in the above application (publication number: CN221981415U), when the user moves up and down on the rope through the descender body, the user rubs against the rope located on the lower side of the descender body through the rubber pad in the friction structure. The friction between the rubber pad and the rope can reduce the descent speed of the descender body on the rope.

[0004] However, in actual use, when the user needs to descend on the rope using the self-locking descender, they should use their left hand to operate the handle while simultaneously holding the rope with their right hand. The user's descent speed depends primarily on the rope's release speed. During rope release, the rope will directly contact the user's hands, generating friction. Improper operation may lead to hand injury; therefore, we propose a safe, anti-panic descender. Utility Model Content

[0005] The purpose of this invention is to provide a safe anti-panic descender to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a safe anti-panic descender, comprising a body, a latch fixedly mounted on the surface of the body, a friction mechanism provided on the surface of the body, and a promoting mechanism provided on the surface of the body, the friction mechanism comprising:

[0007] Buckle plate two, buckle plate two is fixedly installed on the surface of the body, buckle plate two is movably connected to buckle plate one, an arc-shaped friction piece is fixedly installed on the arc surface of buckle plate two, and threaded holes are opened on the surface of buckle plate two;

[0008] A bolt is threaded onto the arc surface of a threaded hole. A guide wheel is movably mounted on the surface of the device body, and an arc block is fixedly mounted on the arc surface of the guide wheel.

[0009] Preferably, the promoting mechanism includes a round rod, which is fixedly installed on the surface of the device body. The arc surface of the round rod is movably connected to a handle. A straight rod is fixedly installed on the surface of the device body. The arc surface of the straight rod is fixedly connected to one end of a torsion spring. The end of the torsion spring away from the arc surface of the straight rod is fixedly connected to the inner wall of the extrusion block.

[0010] Preferably, the surface of the extrusion block is provided with a rotating hole, the diameter of which is adapted to the diameter of the straight rod, and the extrusion block is sleeved on the surface of the straight rod.

[0011] Preferably, the compression block is arc-shaped, and a friction protrusion is provided at one end of the compression block near the guide wheel, thereby restricting the surface of the rope at the end of the compression block.

[0012] Preferably, the surface of the buckle plate one is provided with a through hole, the diameter of the through hole is adapted to the diameter of the bolt, the bolt passes through the buckle plate one, and thus the bolt can fix the buckle plate one and the buckle plate two.

[0013] Preferably, the number of arc blocks is set to several, and the several arc blocks are fixedly installed on the arc surface of the guide wheel in a circumferential array to limit the surface of the rope, thereby ensuring the stable movement of the rope.

[0014] Preferably, both buckle plate one and buckle plate two have arc-shaped friction pads fixedly installed on their arc surfaces to facilitate full contact with the surface of the rope.

[0015] Compared with the prior art, this utility model provides a safe anti-panic descender with the following advantages:

[0016] 1. This safe anti-panic descender features a friction mechanism. As the user moves up and down the rope, the rubber pads in the friction mechanism rub against the rope located on the underside of the descender. This friction reduces the descending speed of the descender body on the rope, thus preventing the rope from directly rubbing against the user's right hand and effectively reducing the possibility of rope abrasion. Additionally, a guide wheel guides the rope's movement, and an arc block limits the rope's surface movement, ensuring stable rope movement.

[0017] 2. This safe anti-panic descender is equipped with a facilitating mechanism. The handle can be manually rotated to squeeze the end of the squeezing block against the surface of the guide wheel, increasing friction and reducing the speed of the rope movement, thereby reducing the possibility of the user's right hand being scratched by the rope.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a safe anti-panic descender, including a body 1, a buckle 2 fixedly installed on the surface of the body 1, a friction mechanism 3 provided on the surface of the body 1, and a promoting mechanism 4 provided on the surface of the body 1. The friction mechanism 3 includes a buckle plate 301, a buckle plate 302, an arc-shaped friction plate 303, a threaded hole 304, a bolt 305, a guide wheel 306, and an arc block 307.

[0024] In one embodiment of this utility model, a second buckle plate 302 is fixedly installed on the surface of the body 1, and a first buckle plate 301 is movably connected to the surface of the second buckle plate 302. An arc-shaped friction plate 303 is fixedly installed on the arc surface of the second buckle plate 302. A threaded hole 304 is opened on the surface of the second buckle plate 302, and a bolt 305 is threadedly connected to the arc surface of the threaded hole 304. A guide wheel 306 is movably installed on the surface of the body 1, and an arc block 307 is fixedly installed on the arc surface of the guide wheel 306.

[0025] Additionally, the promoting mechanism 4 includes a round rod 401, which is fixedly installed on the surface of the device body 1. The arc surface of the round rod 401 is movably connected to the handle 402. A straight rod 403 is fixedly installed on the surface of the device body 1. The arc surface of the straight rod 403 is fixedly connected to one end of a torsion spring 404. The end of the torsion spring 404 away from the arc surface of the straight rod 403 is fixedly connected to the inner wall of the compression block 405. A rotating hole is provided on the surface of the compression block 405. The diameter of the rotating hole is adapted to the diameter of the straight rod 403. The compression block 405 is sleeved on the surface of the straight rod 403. The compression block 405 is arc-shaped. A friction protrusion is provided at the end of the compression block 405 near the guide wheel 306, thereby restricting the surface of the rope at the end of the compression block 405.

[0026] In this embodiment of the utility model, a through hole is provided on the surface of buckle plate 301. The diameter of the through hole is adapted to the diameter of bolt 305. Bolt 305 passes through buckle plate 301, thereby fixing buckle plate 301 and buckle plate 302. Buckle plate 301 and buckle plate 302 are rotatably connected by a hinge seat. A number of arc blocks 307 are provided. The arc blocks 307 are fixedly installed in a circumferential array on the arc surface of guide wheel 306 to limit the surface of the rope, thereby ensuring the stable movement of the rope. Arc-shaped friction plates 303 are fixedly installed on the arc surfaces of buckle plate 301 and buckle plate 302 to facilitate full contact with the surface of the rope.

[0027] In this invention, during use, the rope located on the lower side of the device 1 is placed between buckle plate 1 301 and buckle plate 2 302. Then, the bolt 305 is tightened to fix buckle plate 1 301 and buckle plate 2 302. At this time, the arc-shaped friction plate 303 on the inner side of buckle plate 1 301 and buckle plate 2 302 is in close contact with the rope. Then, the user holds the handle 402 with their left hand and pulls the rope located on the lower side of the device 1 with their right hand. As the user's right hand releases the rope, the rope will first rub against the arc-shaped friction plate 303. The friction between the arc-shaped friction plate 303 and the rope can reduce the downward speed of the device 1 on the rope, thereby reducing the friction between the rope and the user's right hand and effectively reducing the possibility of the user's hand being scratched by the rope. At the same time, a guide wheel 306 is provided to guide the movement of the rope, and the arc block 307 is provided to limit the surface of the rope to ensure stable movement of the rope.

[0028] Furthermore, the handle 402 can be manually rotated, causing the end of the compression block 405 to rotate. The torsion spring 404 deforms, compressing the rope movement on the surface of the guide wheel 306, increasing friction, reducing the rope's movement speed, and thus reducing the possibility of the user's right hand being scratched by the rope. The hand touches the handle 402, and then the torsion spring 404 resets, causing the compression block 405 and the handle 402 to reset.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
