the moment arm increasing member 40 is used for increasing the moment arm of the pulling member 30, wherein the moment arm increasing member 40 is connected to the mounting member 10, the fixing member 21, or the mounting member 10 and the fixing member 21, and the moment arm increasing member 40 is provided with a guide hole 44 at a position far from the mounting member 10 in the extending direction of the locking member 23, and the second end of the pulling member 30 passes through the guide hole 44.

In this embodiment, initially, the direction in which the user pulls the pulling member 30 is generally vertically downward or substantially vertically downward, and the first direction a is generally horizontal or nearly horizontal, that is, the direction in which the user pulls the pulling member 30 is perpendicular or nearly perpendicular to the extending direction of the locking member 23, by means of the moment arm increasing member 40, the moment arm corresponding to the force in which the user pulls the pulling member 30 to rotate the mounting member 10 is increased, and according to the mechanical principle, the moment arm is larger, and the required pulling force is smaller, that is, the user only needs to consume a smaller force to rotate the mounting member 10, and when the mounting member 10 rotates to a certain posture, the locking member 23 is pulled to disengage from the movable member 22, so that the shackle 100 is quickly removed.

Meanwhile, when the ring-shaped part of the high-altitude balloon is fastened to the first connecting ring 25 surrounded by the fixed member 21, the movable member 22 and the locking member 23, wherein the ring-shaped part is the Ω -shaped shackle 200, and the position where the Ω -shaped shackle 200 is mainly fastened to the movable member 22, when the user pulls the second end of the pulling member 30 by hand or other external force, the locking member 23 is pulled while pulling the first end of the pulling member 30 and separated from the movable member 22. At this time, under the combined action of the pulling force of the nylon wire 50 and the pressing action of the other end 222 of the movable member 22 by the Ω -shaped shackle 200, the movable member 22 pivots relative to the fixed member 21 to tilt upward, and simultaneously, the Ω -shaped shackle 200 also slides relative to the movable member 22 under the action of the high air ball buoyancy, and finally, is separated from the shackle 100 from the other end 222 of the movable member 22, so that the shackle 100 is quickly removed.

Referring to fig. 1 to 3, specifically, the moment arm enlarging member 40 in the present embodiment extends along the extending direction of the locking member 23 and away from the mounting member 10, and the guiding hole 44 is formed at the end of the moment arm enlarging member 40.

In other embodiments, the first rope 31 may be fixed to the end of the locking member 23 by other means, such as the first rope 31 having one end passing through the through hole 231 and fastened to the end of the locking member 23 and the other end passing through the guide hole 44 and then connected to the second rope 32.

To better pull the locking member 23, the diameter of the first cord 31 is smaller than the diameter of the second cord 32. Material loss is avoided while ensuring the function of the first rope 31 and the second rope 32. In this embodiment, the diameter of the first rope 31 is in the range of 2-3mm, preferably 2mm; while the second cord 32 has a diameter of 5-7mm, preferably 6mm.

In other embodiments, the pulling member 30 may be a single rope, one end of which is fastened to the end of the locking member 23, and the other end of which passes through the guiding hole 44, which is not limited to this example. In addition, the pulling member 30 may be selected from other materials such as wire rope, etc. according to the tensile strength; of course, the pulling member 30 may also be a flexible pulling member, that is, a flexible material is used to make the flexible pulling member.

Referring to fig. 1, the movable member 22 in the embodiment is preferably an arc-shaped structure, so that the movable member 22 has a larger bearing capacity than other structures, such as a linear structure.

In order to facilitate the installation and setting of the moving direction and range of the moving member 22, one end 221 of the moving member 22 is hinged to the fixed member 21 by a pin.

Referring to fig. 1 to 3, as another preferred embodiment of the present embodiment, the mounting member 10 and the fixing member 21 are integrally formed for easy manufacturing.

The working principle of the shackle 20 of the present embodiment is further described below with reference to the drawings:

when the omega-shaped shackle 200 of the high-altitude balloon is buckled on the first connecting ring 25 surrounded by the fixed part 21, the movable part 22 and the locking part 23, if the shackle 100 is to be disassembled, only the pulling part 30 is pulled downwards, wherein the moment arm corresponding to the force pulling the pulling part 30 to rotate the mounting part 10 is increased due to the arrangement of the moment arm increasing part 40, and under the condition of a certain moment, the larger the moment arm, the smaller the required pulling force is, so that the mounting part 10 can be rotated relatively easily, and the locking part 23 is pulled to be moved away from the locking position locked on the movable part 22; when the locking member 23 is pulled to be removed, under the combined action of the self gravity of the shackle 100, the upward pulling force of the omega-shaped shackle 200 under the action of the high air ball buoyancy and the downward pulling force of the nylon wire 50, the movable member 22 pivots relative to the fixed member 21 to tilt upwards, and simultaneously, the omega-shaped shackle 200 also slides relative to the movable member 22 under the action of the high air ball buoyancy, and finally is separated from the shackle 100 relatively from the other end 222 of the movable member 22, so that the shackle 100 is rapidly removed.

The above-mentioned embodiments of the present invention are not limited to the above-mentioned embodiments, but can be modified, equivalent, and improved within the spirit and principle of the present invention, and are included in the scope of the present invention.
