Abstract

A shackle, comprising a mounting piece (10), a connecting ring assembly (20), a pulling piece (30) and a lever arm increasing piece (40). The connecting ring assembly (20) comprises a fixed piece (21), a moving piece (22) and a locking piece (23), the fixed piece (21), the moving piece (22) and the locking piece (23) being arranged in a circle to form a first connecting ring (25). A first end of the pulling piece (30) is connected to the locking piece (23), the lever arm increasing piece (40) is connected to the mounting piece (10) and/or the fixed piece (21) and provided with a guide hole (44) at a position on the extension direction of the locking piece (23) and away from the mounting piece (10), and a second end of the pulling piece (30) passes through the guide hole (44). The arrangement of the lever arm increasing piece (40) increases the lever arm corresponding to a force by which a user affects the pulling piece (30) in order to rotate the mounting piece (10). According to the principles of mechanics, under a constant torque, a required pulling force is smaller when a lever arm is larger. Therefore, the user need only expend a smaller force to rotate the mounting piece (10), and when the mounting piece (10) rotates to a certain posture, the locking piece (23) is pulled away from the moving piece (22), thereby enabling the shackle to be rapidly removed.

With the force 吋 which can be separated from the movable member 22, after the force is removed, the locking member 23 can also be moved and inserted onto the movable member 22 to ensure that the movable member 22 is locked by the locking member 23 and cannot be locked. Activity

[0039] In order to allow the locking member 23 to be reciprocally disposed on the mounting member 10, so that the locking member 23 is mated with the movable member 22, the abutting member 26 includes an elastic member 261. Specifically, the mounting member 10 is provided. The insertion hole of the locking member 23 is inserted, and the elastic member 261 is sleeved on the locking member 23 and disposed in the insertion hole. Moreover, one end of the elastic member 261 is abutted or fixed to the locking member 23 near the movable member. The other end 222 of the 22 is positioned, and the other end of the elastic member 261 is abutted or fixed to a position where the inner wall of the insertion hole is away from the other end 222 of the movable member 22. Specifically, a flange (not shown) may be disposed on the side of the locking member 23 and the inner side of the insertion hole to the elastic member 2 61 to the top. Thus, the initial cymbal, the locking member 23 is located at the locking position of the locking movable member 22, specifically, it passes through the insertion hole and is inserted into the movable member 22, and is inserted tightly by the elastic force of the elastic member 261. Close to the movable member 22; and when the locking member 23 is pulled by the pulling member 30, the locking member 23 is moved to the unlocking position for releasing the movable member 22 to be separated from the movable member 22, and the lock is locked. The pressing member 23 compresses the elastic member 261 to cause the elastic member 261 to be in a compressed state; and after the pulling member 30 withdraws the force, the force acting on the locking member 23 is also removed, and the elastic member 261 is thereby The elastic restoring force moves the locking member 23 to the initial locking position

[0040] Preferably, the elastic member 261 is a spring for ease of taking materials and mounting settings.

[0041] Referring again to FIG. 1 to FIG. 3, in the preferred embodiment of the locking member 23, the locking member 23 is a pin for facilitating the material and installation; and the movable member 22 is provided with a pin. The hole, the pin and the pin hole are mated to form a latch structure for locking the movable member 26. In addition, one end of the locking member 23 away from the movable member 22 is provided with a through hole 231 for the pulling member 30 to be worn to facilitate the positioning of the pulling member 30.

[0042] In the present embodiment, the pulling member 30 includes a first rope 31 and a second rope 32, wherein the first rope 31 and the second rope 32 are both nylon strings to ensure their toughness and strength; One end of the first rope 31 passes through the through hole 231 and is connected to the other end of the first rope 31, and forms an annular structure to facilitate the connection of the second rope 32; and the first rope 31 passes through the guide hole 44. In connection with the second rope 32, in particular, the second rope 32 is attached to the first rope 31 passing through the guide hole 44. In other embodiments, the first rope 31 can also be fixed to the end of the locking member 23 by other means, such as the first rope 31 end passing through the through hole 231 and fastened to the end of the locking member 23, The other end is connected to the second rope 32 after passing through the guide hole 44.

[0043] In order to better pull the locking member 23, the diameter of the first rope 31 is smaller than the diameter of the second rope 32. Under the premise of ensuring the function of the first rope 31 and the second rope 32, the loss of material is avoided. In the present embodiment, the diameter of the first rope 31 is in the range of 2-3 mm, preferably 2 mm; and the diameter of the second rope 32 is 5-7 mm, preferably 6 mm.

[0044] In other embodiments, the pulling member 30 may also be only a rope, one end is fastened to the end of the locking member 23, and the other end is passed out of the guiding hole 44, which is not in this embodiment. Limited. In addition, depending on the tensile strength, the pulling member 30 may also be selected from other materials, such as steel wire ropes; etc.; of course, the pulling member 30 may also be a flexible pulling member, that is, a flexible material is used to make the flexible pull. Pull the pieces.

[0045] Referring to FIG. 1, a preferred embodiment of the movable member 22 in this embodiment is that the movable member 22 has an arc structure. In order to make the movable member 22 have a larger bearing capacity than other shape structures, such as a linear structure.

[0046] In order to facilitate the installation setting and to set the moving direction and range of the movable member 22, one end 221 of the movable member 22 is hingedly connected to the fixing member 21 by a pin.
