DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-5 The utility model provides a technical solution: in this embodiment, it includes a hook body 1 and a load-bearing block 3, the load-bearing block 3 is fixed to the upper end of the hook body 1, a pull block 6 is provided at the upper right end of the hook body 1, at least two return springs 8 are connected between the pull block 6 and the hook body 1, a pull rod 7 is fixed to the left side of the pull block 6, the pull rod 7 slides through the hook body 1, and the end of the pull rod 7 is rotatably connected to a return shaft 9, an anti-drop rod 2 is fixed to the outside of the return shaft 9, and the end of the anti-drop rod 2 is against the inner wall of the hook body 1;
[0026] When the hook structure is used to hook the rope on an object, and the hook body 1 is in the process of hooking the rope, the anti-drop rod 2 is rotated counterclockwise, and the anti-drop rod 2 drives the return shaft 9 to rotate together until the hook body 1 is hooked to the rope on the object, and the anti-drop rod 2 is released, and the rotational force of the return shaft 9 drives the anti-drop rod 2 to reset, and the end of the anti-drop rod 2 will press against the inner wall of the hook mouth of the hook body 1, and the rope can be protected from dropping off.
[0027] like Figure 1 , 2 As shown in FIG. 5 , in this embodiment, an anti-slip groove 14 is provided at the inner bottom end of the hook body 1 , a support block 13 is provided in the anti-slip groove 14 , and a plurality of strong springs 15 are connected between the lower end of the support block 13 and the inner bottom end of the anti-slip groove 14 .
[0028] When the hook body 1 hooks the rope, the hook body 1 moves up and the rope is pressed down on the support block 13 due to gravity. The support block 13 presses down the strong spring 15, thereby opening the notch of the anti-slip groove 14. The strong spring 15 contracts to apply an oblique force to the pressure generated by the rope, thereby ensuring the bearing strength of the hook body 1. At this time, the rope is located in the notch of the anti-slip groove 14, and then the anti-slip groove 14 is used to limit the rope, which is beneficial to prevent the rope from sliding back and forth along the hook body 1, thereby effectively ensuring the stability of the hook structure when lifting objects, thereby better preventing the hook from coming off.
[0029] like Figure 5 As shown, in this embodiment, an anti-dropping block 10 is fixed at the hook mouth of the hook body 1.
[0030] The anti-slip block 10 is used to limit the position of the lifting rope. Even if the lifting rope is accidentally moved out of the anti-slip groove 14, the anti-slip block 10 is helpful to block and reduce the lateral sliding force generated by the lifting rope. The anti-slip rod 2 is then used to prevent the lifting rope from being damaged due to the excessive lateral sliding force generated by the lifting rope, thereby making the anti-slip effect of the hook structure better.
[0031] like Figure 1-3 As shown, in this embodiment, at least two return springs 8 are connected between the pull block 6 and the hook body 1, a pull rod 7 is fixed on the left side of the pull block 6, the pull rod 7 slides through the hook body 1, and the end of the pull rod 7 is rotatably connected to a return shaft 9, an anti-slip rod 2 is fixed to the outside of the return shaft 9, the end of the anti-slip rod 2 abuts against the inner wall of the hook body 1, the outer diameter of the anti-slip rod 2 is smaller than the outer diameter of the pull rod 7, and a pull ring 5 is fixed on the right side of the pull block 6.
[0032] When the lifting rope needs to be taken out of the hook body 1, the pull ring 5 is used to pull the pull block 6, the pull rod 7, the return shaft 9 and the anti-drop rod 2 outward, so that the hook mouth of the hook body 1 can be conveniently opened, so that the lifting rope on the object can be conveniently taken out of the hook body 1. After the pull ring 5 is loosened, the rebound force of the return spring 8 will drive the pull block 6, the pull rod 7, the return shaft 9 and the anti-drop rod 2 to reset, so that the anti-drop rod 2 can continue to perform anti-drop protection, and the return shaft 9 is rotated counterclockwise to drive the anti-drop rod 2 to rotate, so that the hook mouth of the hook body 1 can be conveniently opened, so that the lifting rope on the object can be conveniently taken out of the hook body 1.
[0033] like Figure 1 , 3 As shown, in this embodiment, a plurality of lamp beads 11 are connected to the surface of the hook body 1 , and a battery 16 is installed in the load-bearing block 3 , and the battery 16 is connected in series with the lamp beads 11 .
[0034] By arranging multiple lamp beads 11 on the surface of the hook body 1 and powering the lamp beads 11 with batteries, the multiple lamp beads 11 form a light shape similar to the hook body 1 after lighting up. The staff can identify the position of the hook body 1 by the shape of the light display, which is conducive to the use of the hook structure in dimly lit places. The staff can hook objects through the hook structure in a timely and accurate manner.
[0035] like Figure 1 As shown, in this embodiment, a lifting ring 4 is fixed to the upper end of the load-bearing block 3 .
[0036] By providing the lifting ring 4, the hook structure can be conveniently installed on the steel wire rope of the crane for use.
[0037] like Figure 1 As shown, in this embodiment, an arc-shaped reinforcement block 12 located below the anti-slip groove 14 is fixed to the lower end of the hook body 1 .
[0038] The arc-shaped reinforcing block 12 is provided to help share the bearing force of the anti-slip groove 14 , so as to prevent the anti-slip groove 14 of the hook body 1 from being damaged due to insufficient bearing force.
[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
