Detailed ways

As shown in Figure 1, Figure 2 and Figure 3, a hook head of a hook-type personal security line includes a hook head body 1, and a hook body 1 is provided inside the hook head body 1 to lock the wire in the hook head body 1. Locking mechanism 2, said locking mechanism 2 comprises the first locking piece 21 that is rotatably connected in the hook head body 1, the second locking piece 22 that is rotatably connected in the hook head body 1, the top end of the first locking piece 21 and the second locking piece At least one clamping hole 20 that is convenient for wire clamping is formed between the top ends of the two locking pieces 22. The inner sidewall of the clamping hole 20 is provided with a protective layer 23 to avoid damage to the wires. The first locking piece 21 and the second locking piece 21 Two locking pieces 22 are provided with a reset device 3, the reset device 3 is a spring or shrapnel. High, the hook head body 1 is provided with a limit block 4 that limits the rotation of the first lock piece 21 and the second lock piece 22, and the limit block 4 includes a block 41 fixedly connected to the hook head body 1, The movable block 42 that is movably connected on the block 41 is provided with a return spring 43 that controls the reset of the movable block 42, and the block 41 is provided with an installation groove 44 that facilitates the installation of the return spring 43. Movable block 42 is provided with the mounting platform 45 that is convenient to back-moving spring 43 installations, and the front end of described movable block 42 is provided with anti-skid pad 41, and the setting of stopper, guarantees that the first locking piece and the second locking piece are not locked, can The movement can be reset freely, and the setting of the anti-skid pad effectively reduces the deformation of the first locking piece and the second locking piece, and the effect is good. The movement of the moving block in the installation groove of the locking block is controlled by the return spring, which can be well controlled. For the clamping of the wires, the first locking piece 21 and the second locking piece 22 are provided with at least one groove 24 that facilitates the formation of the clamping hole 20. When the number of grooves 24 is greater than 2, from top to bottom The radius of the groove 24 gradually decreases in an arithmetic sequence, which can clamp different types of wires, and the clamping effect is good. The radius of the groove gradually decreases in an arithmetic sequence from top to bottom, and the distribution effect Well, to avoid the falling off of the wire, the first locking piece 21 and the second locking piece 22 are arranged symmetrically with respect to the vertical center line of the hook head body 1, and the first locking piece 21 and the second locking piece 22 are arranged between There is a gap 25, and the symmetrical setting ensures the stability and locking effect.
