Technical Field

[0001] The present invention relates to the technical field of locking and releasing ropes and belts, and in particular to a mechanical rope and belt quick release buckle. Background Art

[0002] Most of the existing rope or belt tensioners on the market use the elastic force or tensile force generated by a spring or an elastic body as the clamping force. The clamping force generated is small, easy to loosen, and difficult to adjust.

[0003] Taking shoelaces commonly used in daily life as an example, when people are walking or running, the shoelaces will often become loose due to the continuous tension caused by vibration and impact. It is necessary to stop the work at hand or interrupt the exercise to re-tighten the shoelaces, which brings many inconveniences to daily life; it will affect the performance in the competition. If the shoelaces are loosened during driving or exercise, it may even endanger the safety of oneself and others. These inconveniences are experienced by everyone in daily life. In addition, if the rope or belt is tied too tight, it can effectively prevent automatic loosening, but it is difficult to loosen when it is needed, resulting in a great waste of time. In short, the rope or belt in the prior art cannot be continuously locked when it should be tight, and cannot be efficiently loosened when it is needed. Summary of the invention

[0026] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0027] like Figure 1-8As shown, a mechanical rope quick elastic buckle includes a base 1, a rotating shaft 2 and a flip mechanism 3. The base 1 includes a longitudinal cylinder 11, and the longitudinal cylinder 11 is provided with a first through hole 101 that coincides with the center line of the longitudinal cylinder 11, and a second through hole 102 that is perpendicular to the first through hole 101 and has a center line at the same horizontal height.

[0028] The rotating shaft 2 is located in the second through hole 102 of the base 1 ; a radial hole is provided in the middle of the rotating shaft 2 , which is the fourth through hole 22 ; and a positioning boss 23 is provided on the outer side wall of the rotating shaft 2 .

[0029] The flip mechanism 3 is rotatably connected to the base 1 through the rotating shaft 2; the flip mechanism 3 includes a handle 31 and an elastic "Ω"-shaped buckle 32, and a hole is provided on each of the two side walls of the flip mechanism 3, one of which is a round hole located on the outside of the second through hole 102 of the base 1, and the hole on the other side wall is provided with a groove at the edge of the hole, which is used to cooperate with the positioning boss 23 on the outer wall of the rotating shaft 2, and drive the rotation of the rotating shaft 2 when the flip mechanism 3 flips; the end of the hole wall of the second through hole 102 with one end of the positioning boss 23 is provided with a notch of a quarter arc length, which is used to facilitate the rotation. The positioning boss 23 on the shaft 2 rotates; the two side walls of the flip mechanism 3 are located on the inner side of the two side walls of the base 1; an elastic "Ω"-shaped buckle 32 is provided on the inner side of the flip mechanism 3, and when the handle 31 is pulled, the flip mechanism 3 is buckled with the base 1, and the elastic "Ω"-shaped buckle 32 is clamped together with the longitudinal cylinder 11 to achieve locking; when the handle 31 is pulled in the opposite direction, when the flip mechanism 3 is 90 degrees with the longitudinal cylinder 11, the elastic "Ω"-shaped buckle 32 is separated from the longitudinal cylinder 11, and at this time, the first through hole 101 is connected with the fourth through hole 22, and the rope can pass freely.

[0030] In one embodiment, the fourth through hole 22 realizes radial rotation when the rotating shaft 2 rotates, and the first through hole 101 and the fourth through hole 22 can be adjusted to form a through hole for the rope to pass through.

[0031] As mentioned above, the first through hole 101 and the fourth through hole 22 are mainly used for threading a rope, and the cross section of the rope is generally flat. Therefore, at least one of the first through hole 101 and the fourth through hole 22 is an elliptical hole; of course, it can also be a hole of other shapes.

[0032] In order to better ensure the consistency of the shapes of the first through hole 101 and the fourth through hole 22 so that no obstacles will be caused by the change of the hole shapes during the passage of the rope, it is preferred that the first through hole 101 and the fourth through hole 22 are both elliptical holes and equal in size.

[0033] In one embodiment, the fourth through hole 22 is a tapered hole, and the cross-sectional area of ​​the hole at the rope entrance of the fourth through hole 22 is larger than the cross-sectional area of ​​the hole at the rope exit. Furthermore, the fourth through hole 22 is a tapered elliptical hole, and the cross-section at any position is elliptical, and the ellipse at the rope entrance of the fourth through hole 22 is larger than the ellipse at the rope exit.

[0034] As described above, the fourth through hole 22 is set as a tapered elliptical hole, which gradually decreases from the rope entrance to the rope exit, which is beneficial to the passing efficiency of the rope.

[0035] In one of the embodiments, an operating hole is opened on the side wall of the second through hole 102, which is used to facilitate viewing the crossing status of the rope 4 from the direction of the handle 31 during the crossing process of the rope, and to implement manual intervention as appropriate, and wave the rope 4 with fingers to further improve the crossing efficiency of the rope 4.

[0036] Working principle:

[0037] When the handle 31 and the shaft 2 are rotated to a position of 90 degrees with the base 1, it is in the initial state. The first through hole 101 of the shaft 2 and the fourth through hole 22 of the base 1 are connected to form a through hole, and the rope can freely pass through. At this time, the rope 4 is in a free and loose state, and the length can be adjusted at will.

[0038] When the handle 31 is rotated to a position parallel to the longitudinal cylinder 11 of the base 1 , it is in a locked state.

[0039] The rotating shaft 2 rotates together with the handle 31 driven by the positioning boss 23, and the fourth through hole 22 of the rotating shaft 2 drives the rope in the hole to rotate and wrap the rope part around the rotating shaft 2. The rope is forcibly folded and stuck in the gap between the outer surface of the rotating shaft 2 and the outer side of the second through hole 102 of the base 1, and is clamped and fixed by the clamping force formed by the gap on the rope.

[0040] When the elastic "Ω"-shaped buckle 32 of the handle 31 is inserted into the longitudinal cylinder 11 of the base 1 and is completely fixed, the rotating shaft 2 is locked, and the purpose of fixing the rope is achieved. When the handle 31 is turned over 90 degrees again, it returns to the initial state of loosening.

[0041] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
