Description

Technical Field

[0001] The invention relates to a rope length adjusting mechanism, in particular to a rope length adjusting mechanism which is easy to operate. Background Art

[0002] The rope length adjustment mechanism is a device widely used in outdoor products to adjust the length of the rope, and it needs to have a certain force bearing capacity and self-locking function. The existing rope length adjustment mechanism is a rope length adjustment ring, and the specific structure is a circular ring, on which a vertical wire inlet, a wire passing port on the left, and a fixed port on the right are provided. After the rope enters the circular ring from the wire inlet, it passes through the wire passing port through the rope buckle, and then passes through the circular ring from the fixed port and is fixed by a rope knot. The self-locking function of the rope length adjustment ring is achieved by relying on the turning angle of the rope at the wire inlet and the wire passing port to generate a certain friction between the rope and the circular ring; when adjusting the length of the rope, it is necessary to push the circular ring upward or downward by external force to move the rope in the wire inlet and the wire passing port, thereby tightening or loosening the rope. When tightening the rope, it is necessary to ensure that the direction of the external force applied is correct, otherwise the turning angle of the rope at the wire inlet and the wire passing port will be increased, which will cause great resistance during the tightening of the rope, making the operation very inconvenient, and sometimes even requiring the cooperation of both hands to tighten. In addition, the existing rope length adjustment ring cannot be applied to ropes that require an additional protective cover. Summary of the invention

[0003] The present invention aims to solve the above technical problems existing in the prior art and provides a rope length adjustment mechanism which is easy to operate.

[0004] The technical solution of the present invention is: a rope length adjustment mechanism that is easy to operate, with a circular ring with a horizontal axis, a first wire inlet located on the top, a wire passing port located on the left and a first fixed port located on the right, the circular ring is outerly provided with a rope length adjuster with a vertical axis, the rope length adjuster is provided with a second wire inlet located above the first wire inlet and vertical, an upper limit block located between the first wire inlet and the second wire inlet is fixed on the inner wall of the rope length adjuster, the side wall of the rope length adjuster is provided with a notch, the wire passing port is located on the outside of the notch, and the rope length adjuster is also provided with a second fixed port located below the first fixed port.

[0005] The rope length adjuster is provided with a lower limit block located below the ring, and the second fixing port is located on the lower limit block.

[0006] The upper limit block is in the shape of an arc concentric with the circular ring.

[0007] The left end of the upper limit block is located above the wire passing opening.

[0008] A rope protective sleeve is fixed outside the rope length adjuster.

[0009] When tightening the rope, the present invention only needs to pull the rope length adjuster upwards to automatically rotate the inner ring, reduce the turning angle of the rope between the wire inlet and the wire passing port, overcome the friction between the rope and the ring, and easily tighten the rope; and when loosening the rope, the rope length adjuster only needs to be pushed downwards, and the upper limit block set against the ring can be moved downwards, which is simple to operate. At the same time, the present invention can also set a protective cover outside the rope length adjuster, which is suitable for ropes that need an external protective cover. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic structural diagram of an embodiment of the present invention.

[0011] Figure 2 It is a usage status diagram of an embodiment of the present invention. DETAILED DESCRIPTION

[0012] The easy-to-operate rope length adjustment mechanism of the present invention is as follows Figure 1 As shown, there is a circular ring 1 with a horizontal axis, which is the same as the prior art. The circular ring 1 has a first wire inlet 1-1 located on the top, a wire passing port 1-2 located on the left, and a first fixed port 1-3 located on the right. What is different from the prior art is that the circular ring 1 is outer-mounted with a rope length adjuster 2 with a vertical axis, and the rope length adjuster 2 is provided with a second wire inlet 3 located above the first wire inlet 1-1 and vertically, and an upper limit block 4 located between the first wire inlet 1-1 and the second wire inlet 3 is fixed on the inner wall of the rope length adjuster 2. The upper limit block 4 should be able to resist the circular ring 1 and move down with the rope length adjuster 2. It can be in any shape, preferably an arc shape concentric with the circular ring 1 and with the left end located above the wire passing port 1-2 to avoid affecting the movement of the rope. The side wall of the rope length adjuster 2 has a notch 5, and the wire opening 1-2 is located outside (on the left side) of the notch 5. The rope length adjuster 2 is also provided with a second fixed opening 6 located below the first fixed opening 1-3. The second fixed opening 6 can be set on the side wall of the rope length adjuster 2. It is best to set a lower limit block 7 located below the ring 1 on the rope length adjuster 2, and the second fixed opening 6 is located on the lower limit block 7. A rope protective cover 8 can be fixed outside the rope length adjuster 2 to be suitable for ropes that require an external protective cover. The rope lock protective cover 8 can be made of elastic material (such as retractable fabric, etc.) and fixed to the outside of the rope length adjuster 2 by a webbing or other device. When adjusting the rope, just hold the rope length adjuster 2 through the rope lock protective cover 8 to operate.

[0013] The usage status of the embodiment of the present invention is as follows Figure 2 As shown: the rope 9 is passed through the second wire inlet 3, the first wire inlet 1-1 in sequence, and then enters the ring 1 from the first wire inlet 1-1, then passes through the wire pass through the rope buckle 10, and then passes through the second fixing hole 6 and the first fixing hole 1-3 in sequence, and is fixed by a rope knot after entering the ring 1. A rope knot can also be set at the outside of the second fixing hole 6.

[0014] Rope tightening: When the rope length adjuster 2 is initially pulled upward, the ring 1 rotates counterclockwise under the action of the rope 9, reducing the turning angle of the rope between the first wire entry port 1-1 and the wire passing port 1-2, or even making the turning angle zero. Then, the rope length adjuster 2 is pulled upward, and the knot of the rope 9 moves upward with the rope length adjuster 2, and the rope moves between the first wire entry port 1-1 and the wire passing port 1-2, and the length of the entire rope system becomes shorter.

[0015] Rope loosening: push the rope length adjuster 2 downward, the upper limit block 4 moves downward against the ring 1, and the rope 9 also moves downward and moves in the first wire inlet 1-1 and the wire passing port 1-2 under the action of external force, and the length of the entire rope system becomes longer.
