本发明所述可回收的抓钩在不使用时，抓钩可以单独存放，也可以使卡栓4与绳索9连接后一起存放，卡栓4与卡锁3处于解锁状态，钩爪2未被固定，可绕固定筒1上下自由旋转， 存储体积小，携带方便，而且不易伤人，安全性高；需要使用抓钩时，使卡栓 4 和卡锁 3 之间旋转卡合，此时卡栓 4 卡住钩爪 2 使钩爪 2 保持固定，钩爪 2 的具体固定角度可根据实际需要设计，此时可以把抓钩投掷到高处使用；当需要回收抓钩时，旋转绳索 9 ，使绳索 9 旋转数圈后带动卡栓 4 旋转，由于所述卡锁 3 和卡栓 4 之间旋转解锁机构的存在，卡栓 4 旋转至一定角度时卡锁 3 与卡栓 4 之间解锁，卡栓 4 释放钩爪 2 ，由于钩爪 2 是可绕固定筒 1 上下自由旋转的，所以钩爪 2 可以脱离树木、岩石等物体，从而实现回收重复利用的目的，实用性非常高。 When the retrievable grapple of the present invention is not in use, the grapple can be stored separately, or the card plug 4 can be stored together with the rope 9 and the latch 4 and the latch 3 are in an unlocked state, and the hook 2 is not Fixed, can rotate freely up and down around the fixed cylinder 1, The storage volume is small, the carrying is convenient, and it is not easy to injure and the safety is high; when the grapple is needed, the card plug 4 and the latch 3 are rotated and engaged, and the latch 4 catches the hook 2 to make the claw 2 Keep fixed, hook 2 The specific fixed angle can be designed according to actual needs. At this time, the grab hook can be thrown to a high place for use; when the grab hook needs to be recovered, the rope 9 is rotated, and the rope 9 is rotated a few times to drive the card bolt 4 to rotate, because the card Lock 3 The rotation of the unlocking mechanism between the latch 4 and the latch 4 is unlocked between the latch 3 and the latch 4 when the latch 4 is rotated to a certain angle, and the latch 4 releases the hook 2, since the hook 2 can be wound around the fixed cartridge 1 The upper and lower sides are free to rotate, so the claws 2 can be separated from objects such as trees and rocks, thereby achieving the purpose of recycling and recycling, and the utility is very high.
在本实施例中，所述固定筒 1 上设有固定销 11 ，所述钩爪 2 上设有通孔 22 ，所述钩爪 2 通过所述通孔 22 套设在固定销 11 上，从而实现上下自由旋转。In the embodiment, the fixing cylinder 1 is provided with a fixing pin 11 , and the hook 2 is provided with a through hole 22 , and the hook 2 The through hole 22 is sleeved on the fixing pin 11 to achieve free rotation up and down.
在本实施例中，所述卡栓 4 上设有卡舌 42 ，所述卡锁 3 为固定卡垫 31 ，所述固定卡垫 31 上设有与所述卡舌 42 形状相对应的缺口 32 ，所述卡舌 42 和固定卡垫 31 形成所述旋转解锁机构，所述卡栓 4 上的卡舌 42 旋转至所述缺口 32 处使卡锁 3 和卡栓 4 之间解锁，所述卡舌 42 的面积远远小于固定卡垫 31 的面积，所以卡舌 42 受到不可测外力旋转至缺口 32 处并脱出的机率非常小，即抓钩的安全性高。In this embodiment, the latch 4 is provided with a tab 42 , and the latch 3 is a fixed card pad 31 , and the fixed card pad 31 A notch 32 corresponding to the shape of the tab 42 is provided, and the tab 42 and the fixed card pad 31 form the rotation unlocking mechanism, and the tab 42 on the latch 4 rotates to the notch 32 The unlocking between the latch 3 and the latch 4 is performed, and the area of the tab 42 is much smaller than the area of the fixed card pad 31, so the tab 42 is rotated by the undetectable external force to the notch 32. The probability of getting out and getting out is very small, that is, the safety of the hook is high.
在本实施例中，所述卡栓 4 上设有卡帽 41 ，所述钩爪 2 上设有卡持台阶 21 ，所述卡帽 41 与所述卡持台阶 21 卡合以使所述钩爪 2 保持固定，可以承受攀登时的力，所述卡栓 4 弹出后使钩爪 2 获得释放并可自由上下转动，有利用存放或者用于回收抓钩。In the embodiment, the latch 4 is provided with a cap 41, and the hook 2 is provided with a holding step 21, and the cap 41 Engaged with the holding step 21 to keep the hook 2 fixed, can bear the force at the time of climbing, and the hook 4 is ejected to make the claw 2 It is released and can be freely rotated up and down, used for storage or used to recover the grapple.
在本实施例中，为了使卡栓 4 能够顺利地解锁，在所述固定筒 1 内还设有在卡栓 4 被解锁后使卡栓 4 弹出的弹簧 5 ，所述弹簧 5 一端抵接在固定卡垫 31 上，另一端抵接在卡栓 4 的卡帽 41 上。In this embodiment, in order to enable the latch 4 to be smoothly unlocked, the fixed cartridge 1 is further provided with a latch 4 after the latch 4 is unlocked. The spring 5 is ejected, and one end of the spring 5 abuts on the fixed pad 31, and the other end abuts on the cap 41 of the latch 4.
在本实施例中，所述卡栓 4 上连接有承重块 6 ，所述固定筒 1 还包括底部，所述承重块 6 与固定筒 1 的底部内壁接触，所述承重块 6 与绳索 9 连接，在使用时，承重块 6 承受大部分或全部拉力，而卡舌 42 和固定卡垫 31 之间并不承受太多的轴向拉力，可以大大降低卡舌 42 和固定卡垫 31 的设计强度。In this embodiment, a load bearing block 6 is connected to the latch 4, and the fixed cylinder 1 further includes a bottom portion, the load bearing block 6 and the fixed cylinder The bottom inner wall of 1 is in contact, and the load-bearing block 6 is connected to the rope 9, and in use, the load-bearing block 6 is subjected to most or all of the pulling force, and the tab 42 and the fixed card pad 31 There is not much axial tension between them, which greatly reduces the design strength of the tab 42 and the fixed pad 31.
在本实施例中，所述承重块 6 和卡栓 4 之间还设有用于延迟扭力传递的分力连接环 7 ，所述分力连接环 7 具体由多个环串接而成，在抓钩的实际使用中，由于绳索 9 为柔性的，在被拉紧时有可能会产生较大的扭矩，如果该扭矩直接传递给承重块 6 和卡栓 4 ，卡栓 4 和卡锁 3 之间存在解锁的风险，形成不安全因素，In this embodiment, a load-carrying connection ring 7 for delaying the transmission of the torsion is further disposed between the bearing block 6 and the latch 4, and the force-joining connection ring 7 Specifically, a plurality of rings are connected in series. In the actual use of the grapple, since the rope 9 is flexible, a large torque may be generated when being tightened, if the torque is directly transmitted to the bearing block 6 and Card plug 4, card plug 4 There is a risk of unlocking between the lock and the lock 3, which creates an insecure factor.
本发明设置的分力连接环 7 可以延迟扭力传递，即在绳索 9 旋转数圈后才能把扭矩传递给承重块 6 ，承重块 6 旋转数圈后才能通过分力连接环 7 把扭矩传递给卡栓 4 ，从而延迟了扭力传递，进一步提高了抓钩的安全性。更具体的，所述固定筒 1 的底部为锥形，所述承重块 6 为承重锥，所述承重锥与固定筒 1 的锥形底部内壁之间还设有锥形弹簧 8 ，所述承重锥和固定筒 1 的锥形底部受力后具有对中性，可避免承重锥对卡栓 4 产生具有不良影响的径向力；在一些特殊的环境下或极端使用过程中，比如在雪山上或者高温火灾现场，承重锥和固定筒 1 的锥形底部有可能因结冰或高温粘结，导致承重锥无法与固定筒 1 的锥形底部分离和旋转，设置锥形弹簧 8 就可以有效解决这个问题，锥形弹簧 8 与承重锥和固定筒 1 的锥形底部接触面积大幅减小，从而减小粘结的可能性。The force component connection ring 7 provided by the invention can delay the transmission of the torque, that is, the torque can be transmitted to the bearing block after the rope 9 is rotated a few times. After the bearing block 6 is rotated a few times, the torque can be transmitted to the card plug 4 through the force component connecting ring 7 , thereby delaying the torque transmission and further improving the safety of the grapple hook. More specifically, the fixed cylinder 1 The bottom of the load bearing block 6 is a load-bearing cone, and a tapered spring 8 is further disposed between the load-bearing cone and the inner wall of the tapered bottom of the fixed cylinder 1, the load-bearing cone and the fixed cylinder 1 The tapered bottom is neutral after being stressed, which avoids the radial force that the load-bearing cone has a bad influence on the plug 4; in some special circumstances or during extreme use, such as on a snowy mountain or a high-temperature fire scene, Bearing cone and fixed cylinder The conical bottom of 1 may be icy or high temperature bonded, so that the bearing cone cannot be separated and rotated from the conical bottom of the fixed cylinder 1, and the conical spring 8 can effectively solve this problem. The contact area with the tapered bottom of the load-bearing cone and the fixed cylinder 1 is greatly reduced, thereby reducing the possibility of sticking.
本实施例中，所述分力连接环也可以为分力连接绳，能获得基本相同的有益效果。In this embodiment, the component force connecting ring can also be a component force connecting rope, and substantially the same beneficial effects can be obtained.
