[0017] The technical scheme of the hook is further described below in combination with the drawings and specific embodiments.

[0018] EMBODIMENT

[0019] As Figures 1-3 shown, the hook provided by the utility model is an outer opening type hook with a rotating check wheel, which comprises an assembly weight 1, a connection turntable 2 is arranged below the assembly weight 1, a mounting end of the connection turntable 2 is mounted in correspondence with one end of the assembly weight 1,

[0020] The mounting end of the adapter turntable 2 is fixedly connected with the assembly plummet 1. The side of the adapter turntable 2 away from the assembly plummet 1 is provided with a lifting hook 3. The mounting end of the lifting hook 3 is correspondingly mounted with the lower end of the adapter turntable 2. The mounting end of the lifting hook 3 is fixedly connected with the adapter turntable 2. The setting of the adapter turntable 2 can make the lifting hook 3 rotate, so that the lifting hook 3 is more convenient in hoisting operation. The lifting hook 3 is provided with a protruding block 4 on one side. The mounting end of the protruding block 4 is correspondingly mounted with one side of the lifting hook 3. The mounting end of the protruding block 4 is fixedly connected with one side of the lifting hook 3. The protruding block 4 is provided with two mounting shafts 5 on both sides. The mounting end of the mounting shaft 5 is correspondingly mounted with both sides of the protruding block 4. The mounting end of the mounting shaft 5 is fixedly connected with the protruding block 4. The mounting shaft 5 is provided with a clasp buckle 6. The clasp buckle 6 comprises a connecting sleeve 61. The connecting sleeve 61 is provided with a shaft hole. The mounting shaft 5 is correspondingly mounted with the shaft hole. The connecting sleeve 61 is sleeved on the outside of the mounting shaft 5. The connecting sleeve 61 is rotatably connected with the mounting shaft 5. The outer circle of the connecting sleeve 61 is respectively provided with a clasp 62 and an adjusting buckle 63. The clasp 62 and the adjusting buckle 63 are both provided in a "U" shape. The mounting end of the clasp 62 and the adjusting buckle 63 is correspondingly mounted with the outer circle of the connecting sleeve 61. The mounting end of the clasp 62 and the adjusting buckle 63 is fixedly connected with the connecting sleeve 61. The adjusting buckle 63 is sleeved on the outside of the lifting hook 3. The setting of the clasp buckle 6 can block the hook-shaped end of the lifting hook 3, so that the lifting hook 3 can be better taken and installed with the lifting rope.

[0021] The end of the lifting hook 3 away from the protruding block 4 is provided with a check wheel 7. The check wheel 7 comprises a wheel shaft 71. The lifting hook 3 is provided with a mounting hole. The wheel shaft 71 is correspondingly mounted with the mounting hole. The mounting end of the wheel shaft 71 is fixedly connected with the mounting hole. The outer circle of the wheel shaft 71 is sleeved with a wheel cylinder 72. The mounting end of the wheel cylinder 72 is correspondingly mounted with one end of the wheel shaft 71. The wheel cylinder 72 is provided with an assembly hole. The wheel cylinder 72 is rotatably connected with the wheel shaft 71 through the assembly hole. The wheel shaft 71 is provided with a pressing switch. When the pressing switch is in an initial state, the wheel cylinder 72 cannot rotate clockwise, so that the wheel cylinder 72 can be limited and blocked. When the pressing switch is pressed, the wheel cylinder 72 can rotate counterclockwise. The outer circle of the wheel cylinder 72 is provided with a plurality of wheel plates 73. The mounting end of the wheel plate 73 is correspondingly mounted with the outer circle of the wheel cylinder 72. The wheel plate 73 is fixedly connected with the wheel cylinder 72. When the clasp 62 is in a closed state, the wheel plate 73 blocks the clasp 62. When the wheel plate 73 blocks the clasp 62, the pressing switch on the wheel shaft 71 is in an initial state. The setting of the check wheel 7 can limit the clasp buckle 6, so that the clasp 62 cannot be randomly rotated when the lifting hook 3 hoists goods, thereby improving the safety of hoisting operation. The clasp buckle 6 is provided in an outward opening shape, so that the lifting rope is more convenient to unhook and take down.

[0022] In the embodiment, when the operator needs to use the device to hoist goods, the operator first presses the press switch on the wheel shaft 71, so that the wheel cylinder 72 can drive the wheel plate 73 to rotate counterclockwise. Then the operator assembles the lifting rope with the lifting hook 3. Finally, the operator releases the press switch on the wheel shaft 71, and then adjusts the adjusting buckle 63. The adjusting buckle 63 drives the clasp ring 62 to rotate through the connecting sleeve 61, so that the clasp ring 62 rotates to the inside of the lifting hook 3. At this time, the wheel plate 73 resists the clasp ring 62, thereby completing the assembly of the lifting rope.

[0023] When the operator needs to remove the lifting rope, the operator only needs to press the press switch on the wheel shaft 71, and then rotate the adjusting buckle 63 to open the clasp ring 62 outward to remove the lifting rope.

[0024] The above specific embodiments are only preferred embodiments of the present application. Based on the technical scheme of the present application and the related inspiration of the above embodiments, those skilled in the art can make various alternative improvements and combinations on the above specific embodiments.
