DETAILED DESCRIPTION

[0013] 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 of 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.

[0014] Depend on Figures 1 to 3 The utility model comprises a suspension rod 1, a suspension hook body 2, two rotatable and adjustable rotation bars 3, two telescopic and adjustable L-shaped rods 4, a limiting rod 5 and a limiting slot 6. The suspension hook body 2 is fixedly connected to the bottom of the suspension rod 1, and the suspension hook body 2 and the suspension rod 1 are integrally cast and formed. The two rotation bars 3 are connected to both sides of the suspension hook body 2, and the two L-shaped rods 4 are respectively connected to the bottom of the two rotation bars 3. The limiting rod 5 is fixedly connected between the bottoms of the two L-shaped rods 4. The limiting slot 6 is arranged inside the hook tip of the suspension hook body 2, and the limiting rod 5 is located inside the limiting slot 6. The upper parts of both sides of the suspension hook body 2 are rotatably connected with a rotation axis 7, and the two rotation bars 3 are respectively fixedly connected to the ends of the two rotation axes 7. Both sides of the suspension rod 1 are fixedly connected with a fixed block 8, and one side of the two fixed blocks 8 is fixedly connected with a first spring 9. One end of the two first springs 9 is respectively fixedly connected to the surface of the two rotation bars 3, so that the two rotation bars 3 can effectively perform rotation adjustment and automatic reset adjustment.

[0015] When in use, the lifting rope is placed on the hook tip of the hook body 2, and then the two L-shaped rods 4 are squeezed by the weight of the lifting rope. After the two L-shaped rods 4 are squeezed, the two rotating bars 3 will rotate through the rotating shaft 7. The rotation of the two rotating bars 3 will compress the two first springs 9. At the same time, the rotation of the two rotating bars 3 will drive the two L-shaped rods 4 and the limiting rod 5 to rotate, so that the limiting rod 5 moves to the inside of the hook body 2, and then the lifting rope will fall into the inside of the hook body 2, and then the elastic restoring force of the first spring 9 will make the rotating bar 3, the L-shaped rod 4 and the limiting rod 5 rotate and reset, so that the limiting rod 5 is stuck in the inside of the limiting slot 6 to prevent the lifting rope from falling off.

[0016] A slot 10 is provided in the middle of the two rotating bars 3. The middle of the slot 10 is large and the two ends are small. The tops of the two L-shaped rods 4 are movably inserted into the inside of the two slots 10, and a slider 11 is slidably installed in the middle of the two slots 10. The top of the L-shaped rod 4 is fixedly connected to the slider 11. A second spring 12 is fixedly connected between one side of the slider 11 and the inside of the slot 10, so that the L-shaped rod 4 can be effectively telescopically adjusted. One side of the two sliders 11 is fixedly connected with an insertion rod 13, and the insertion rod 13 is located in the middle of the second spring 12. , and the tops of the two plug rods 13 pass through the slot 10 and extend to the outside of one end of the rotating bar 3, a fixed plate 14 is fixedly connected between the tops of the two plug rods 13, and one end of the two rotating bars 3 is fixedly installed with a fixed block 2 15, and a rotating shaft 2 16 is rotatably connected between the two fixed blocks 2 15, and the rotating shaft 2 16 is located below the fixed plate 14, and the middle of the rotating shaft 2 16 is fixedly connected with an eccentric extrusion wheel 17 in contact with the fixed plate 14, and one end of the rotating shaft 2 16 is fixedly connected with an adjusting wheel 18, so that it can be effectively adjusted;

[0017] When it is necessary to remove the lifting rope from the hook body 2, the adjusting wheel 18 is rotated to make the rotating shaft 16 drive the eccentric extrusion wheel 17 to rotate. The rotation of the eccentric extrusion wheel 17 will push the fixing plate 14, so that the fixing plate 14 drives the two insertion rods 13 to move out from the inside of the two slots 10. The movement of the two insertion rods 13 will pull the two sliders 11 to move. The movement of the two sliders 11 will compress the second spring 12 and drive the two L-shaped rods 4 and the limiting rod 5 to move, so that the limiting rod 5 moves out from the inside of the limiting slot 6 and moves away from the opening of the hook body 2, thereby facilitating the removal of the lifting rope from the hook body 2.

[0018] In order to prevent the lifting rope from falling off the lifting hook, the novel lifting hook structure is provided with a one-way movable anti-falling structure, the one-way movable anti-falling structure can conveniently install the lifting rope, and the one-way movable anti-falling structure can effectively perform telescopic adjustment, and the telescopic adjustment can be operated by one person, so that the lifting rope can be conveniently removed from the lifting hook, thereby making the use of the lifting hook more convenient and helping to improve the practicality of the lifting hook.

[0019] The novel hook structure is simple in design, easy and convenient to operate, stable and reliable to use, and its performance can meet people's use needs.
