Description

Technical Field

[0001] This utility model relates to the field of outdoor sports equipment such as rock climbing and rescue, and specifically to a rope adjuster and an adjustable sling that can adjust the rope length under stress. Background Technology

[0002] In outdoor rock climbing or rope ascent and descent, a rope adjuster is usually placed near the climber's rope to control its overall length. Currently, most rope adjusters are pre-adjusted before climbing or outdoor activities, and users use this pre-adjusted length. They lack the ability to adjust the rope under load during use. If a climber gets tired or wants to rest for other reasons, there's no way to adjust and tighten the rope to allow for rest, making it very inconvenient. Therefore, a rope adjuster that allows for length adjustment under load is essential. Utility Model Content

[0003] To address the problems in the prior art, this utility model provides a rope adjuster capable of adjusting the rope length under stress, and also provides an adjustable sling including the rope adjuster capable of adjusting the rope length under stress.

[0004] This utility model relates to a rope adjuster capable of adjusting rope length under stress. It includes an adjuster body, a guide hole on the adjuster body for a safety hook to pass through and guide the movement of the safety hook, and a first rope hole and a second rope hole located below the adjuster body for the rope to enter and exit. The adjuster body also has a first channel communicating with the first rope hole and a second channel communicating with the second rope hole. The other end of the first channel communicates with the second channel through the guide hole. A rope limiting structure is provided on the inner wall of the guide hole near the second rope hole. The rope limiting structure cooperates with the safety hook in the guide hole to lock the rope. The safety hook moves along the guide hole towards the end away from the rope limiting structure, disengaging the rope from the rope limiting structure and entering an adjustable length state. The rope adjuster also includes an adjustment structure that drives the adjuster body to rotate, thereby driving the safety hook to move.

[0005] Furthermore, the adjustment structure includes a first lever and a second lever, which are disposed at both ends of the guide hole.

[0006] Furthermore, the force-bearing surface of the guide hole and the safety hook includes a first inclined surface and a second inclined surface set at a certain angle, and the first and second levers are equally spaced on both sides of the junction of the first and second inclined surfaces.

[0007] Furthermore, the first and second levers can drive the regulator body to rotate at a certain angle, causing the safety hook to move to the second inclined plane. The rotation torque point of the first and second levers is set at the junction of the first and second inclined planes.

[0008] Furthermore, the first rope hole is located below the junction of the first inclined plane and the second inclined plane, and the second rope hole is located on the side of the first rope hole away from the second inclined plane.

[0009] Furthermore, the first lever is a first protrusion extending from the regulator body, and the second lever is a second protrusion extending from the regulator body.

[0010] Furthermore, the second thumb ring includes several stepped surfaces that engage with the fingers.

[0011] Furthermore, the regulator body consists of two identical adjustment plates spaced at a certain interval. The guide hole is located in the middle of the adjustment plates. The two adjustment plates are fixed by four rivets on the outer periphery of the adjustment plates. A first rope hole is formed between the first and second pins, and a second rope hole is formed between the second and third pins. The third pin is located on the second lever, and the fourth pin is located on the first lever. The rope limiting structure is fixed between the two adjustment plates.

[0012] Furthermore, the second pin is positioned diagonally below the rope limiting structure away from the first ring.

[0013] This utility model also provides an adjustable rope, including the rope adjuster that can adjust the rope length under force, and a safety hook and a rope. The safety hook is inserted into the guide hole. One end of the rope can be inserted through the first rope hole, through the first channel, through the safety hook in the guide hole, then through the second channel, and finally out through the second rope hole. The rope limiting structure can cooperate with the safety hook to lock the rope in a locked state. The adjusting structure is used to drive the adjuster body to rotate and adjust the locked state or the adjustable length state of the rope.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the guide hole, first rope hole and second rope hole structure of this utility model, the rope is connected and cooperated with the safety hook inside the regulator body, and a rope limiting structure is provided on the inner wall of the first rope hole. During operation, it is only necessary to flip the regulator body to make the rope disengage from the rope limiting structure, so as to realize the release of the rope under stress, adjust the length of the rope independently, prevent the climber from falling, and allow the climber to stop in the air, rest for a while, and achieve a comfortable resting state.

[0015] This utility model, through ergonomic design, sets a first and a second lever at both ends of the regulator body. The thumb operates the first lever, while other fingers can be placed on the second lever for better grip and to change the angle of the regulator body. Without the aid of tools, the operation is transformed from pressing down with one finger to operating with the entire palm and several fingers, making it easier for the operator to operate and improving the convenience of operation.

[0016] By setting the first and second levers, the two lever arms are appropriately lengthened, and the direction conversion point of the regulator body, which is the intersection of the first and second inclined planes, is set at the center of the torque point of the rotation of the first and second levers. This minimizes the force on the connector body, allowing it to flip. Then, the safety hook drives the rope to slide automatically along the first or second inclined plane under the action of gravity, achieving the locking or releasing of the rope, further improving the convenience of adjustment.

[0020] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, and accompanying drawings are used to distinguish different objects, not to describe a particular order.

[0021] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] like Figures 1-5 As shown, the adjustable cable of this utility model can adjust its length under stress. Specifically, the adjustable cable in this example includes a rope adjuster 100, a safety hook 200, and a rope 300. The rope adjuster 100 and the safety hook 200 work together to lock or release the rope 300.

[0024] Specifically, the rope adjuster 100 in this example includes an adjuster body 1, a guide hole 4 on the adjuster body 1 for the safety hook 200 to pass through and guide the movement of the safety hook 200, and a first rope hole 2 and a second rope hole 3 located below the adjuster body 1 for the rope to enter and exit respectively. The adjuster body also has a first channel communicating with the first rope hole 2 and a second channel communicating with the second rope hole 3. The other end of the first channel communicates with the second channel through the guide hole 5. The inner wall of the guide hole 4 near the second rope hole 3 is provided with a rope limiting structure 6. The rope limiting structure 6 cooperates with the safety hook 200 in the guide hole 4 to lock the rope. When the safety hook 200 moves along the guide hole 4 away from the rope limiting structure 6, the rope 300 disengages from the rope limiting structure 6 and is in an adjustable length state. Conversely, when it is necessary to lock the rope, the safety hook 200 moves along the guide hole 4 towards the rope limiting structure 6 and cooperates with the rope limiting structure 6 to lock the rope 300. In this example, the rope adjuster 100 also includes an adjustment structure 5 that drives the adjuster body 1 to rotate, thereby driving the safety hook to move. Preferably, in this example, the interiors of the first channel, the second channel, and the guide hole are interconnected cavities.

[0025] The adjustment structure 5 in this example includes a first lever 51 and a second lever 52 extending from the regulator body 1, with the first lever 51 and the second lever 52 positioned at both ends of the guide hole 4. By ensuring that the first lever 51 and the second lever 52 are subjected to forces in the same direction, the regulator body 1 can be rapidly rotated.

[0026] Preferably, the regulator body 1 in this example is fan-shaped. The force-bearing surfaces of the guide hole 4 and the safety hook include a first inclined plane 401 and a second inclined plane 402 set at a certain angle. The first lever 51 and the second lever 52 are equidistantly arranged on both sides of the junction of the first inclined plane 401 and the second inclined plane 402. By setting the first lever 51 and the second lever 52, the two lever arms are appropriately lengthened, and the direction conversion point of the regulator body 1, that is, the junction a of the first inclined plane 401 and the second inclined plane 402, is set at the center of the torque point of the rotation of the first lever 51 and the second lever 52. This minimizes the force on the connector body, allowing it to flip. Then, the safety hook drives the rope to automatically slide along the first inclined plane 401 or the second inclined plane 402 under the action of gravity, realizing the locking or releasing of the rope, further improving the convenience of adjustment.

[0027] Preferably, in this example, the first rope hole 2 is located below the junction a of the first inclined surface 401 and the second inclined surface 402, and the second rope hole 3 is located on the side of the first rope hole 2 away from the second inclined surface 402. Thus, when the regulator body 1 is under tension on the rope, the tensioned end of the rope can be vertically downward, and the first lever 51 and the second lever 52 are positioned at equal intervals on both sides of the junction a.

[0028] In a preferred embodiment of this utility model, the connector body 1 consists of two identical adjusting plates 11 and 12 spaced at a certain interval. The guide hole 4 is located in the middle of the adjusting plates 11 and 12. The two adjusting plates are fixed together by four rivets around their outer periphery. A first rope hole 2 is formed between the first pin 7 and the second pin 8, and a second rope hole 3 is formed between the second pin 8 and the third pin 521. The third pin 521 is located on the second finger 52, and the fourth pin 511 is located on the first finger 51. The rope limiting structure is fixed between the two adjusting plates and faces inward toward the guide hole 4. This results in a simpler structure, easier processing, and facilitates the connection and coordination between the rope 300, the safety hook 200, and the rope adjuster 100. It also eliminates the need to consider interference between the rope 300 and the interior of the connector body 1.

[0029] Preferably, in this example, the first lever 51 is a first protrusion extending from the regulator body 1, and the fourth pin 511 is located in the middle of the first protrusion. In this example, the second lever 52 is a second protrusion extending from the regulator body 1, and the third pin 521 is located in the middle of the second protrusion. Several stepped surfaces 522 are provided on the side of the third pin 521 away from the second rope hole 3. In this example, there are two stepped surfaces, which, in conjunction with two of the four fingers (excluding the thumb), better facilitate the gripping of the connector body 1. The operator pushes the fourth pin 511 of the first lever 51 upwards with their thumb and presses down on the stepped surfaces with their other fingers, thereby making it easier to flip the regulator body 1.

[0030] Of course, the regulator body 1 in this example can also be integrally formed by die casting or injection molding without the need for connecting pins. Instead, it can be flipped by acting on the sidewalls of the first and second protrusions. Specifically, in this example, a first sidewall 512 and a second sidewall 513 are provided on both sides of the first protrusion. The operator uses his thumb to push the first sidewall 512 of the first lever 51 to drive the regulator body 1 to flip. Similarly, a third sidewall 522 is provided on the side of the second protrusion away from the second rope hole 3. The third sidewall 522 is provided with several stepped surfaces for cooperation with the fingers.

[0031] The working principle of this example is as follows:

[0032] like Figure 4 As shown, in this example, when locked, the safety hook 200 is located at the junction a of the first inclined plane 401 and the second inclined plane 402. The non-load-bearing end of the rope 300 is pressed against the rope limiting structure 6, and the non-load-bearing free end extends out from the second rope hole 3. Figure 5 As shown, when the length of the rope 300 needs to be adjusted, the hand holds the connector body 1, the thumb pushes the first side wall 512 or the fourth pin 511 of the first lever 51 upwards, and the other fingers are placed on the second lever 52 to press down, thereby driving the adjuster body 1 to rotate at a certain angle. Under the action of gravity, the safety hook 200 moves to the second inclined plane 402, and the rope 300 is released from the rope limiting structure 6, and the length of the rope can be freely adjusted.

[0033] Furthermore, the structural design of this invention also enables the automatic restoration of the rope's locked state. When it is necessary to adjust the rope from the adjustable state to the locked state, simply move your hand away from the rope adjuster. Since the first rope hole 2 is located below the first inclined plane 401, in the adjustable state, the safety hook is located to the upper right of the fourth pin 511. Under the action of the fourth pin 7, the rope at the force-bearing end pulls the safety hook to the left, eventually moving to the junction of the first inclined plane 401 and the second inclined plane 402, thereby tightening the rope.

[0034] This utility model, through ergonomic design and the addition of a release function, allows climbers of different heights and weights to adjust the rope length according to their own needs. Of course, if climbers get tired or want to rest for other reasons during the climb, the adjustable carabiner can temporarily lock the rope to prevent slippage and a fall, allowing them to pause in mid-air for a short rest. Alternatively, the adjustable carabiner can be attached to an anchor point, and climbers can release the rope adjuster to independently adjust the length of the carabiner and rope to achieve a comfortable resting position.

[0035] The specific embodiments described above are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
