DETAILED DESCRIPTION

[0020] The utility model is further described below with reference to the accompanying drawings.

[0021] like Figure 1-Figure 7 As shown, a stud 6-1 is provided below the screw seat 6, a connection hole 6-2 is provided above the screw seat 6, an annular groove 6-3 is provided in the connection hole 6-2, the top of the screw seat 6 is connected to the hook 3, a plurality of claws 3-1 are provided below the hook 3 on the outside, a boss 3-2 is provided below the claw 3-1, the boss 3-2 is inserted into the groove 6-3, and the hook 3 is connected to the sling 7. First, the screw seat 6 is installed on the threaded hole of the equipment through the stud 6-1, and then the claw 3-1 of the hook 3 is inserted into the installation hole above the screw seat 6, so that the boss 3-2 is inserted into the groove 6-3, and the hook 3 is connected to the sling 7 to achieve the installation of the sling 7.

[0022] A threaded hole is provided in the middle of the hook 3, and a screw 2 is installed in the threaded hole. The diameter of the head of the screw 2 is larger than the diameter of the top of the hook 3, and one end of the sling 7 is annularly sleeved under the head of the screw 2. First, the annular end of the sling 7 is sleeved on the outside of the top of the hook 3, and then the screw 2 is installed on the top of the hook 3. The head diameter of the screw 2 is larger than the outer diameter of the top of the hook 3 and the inner diameter of the annular part of the sling 7, which can prevent the sling 7 from falling out and realize the connection between the sling 7 and the hook 3.

[0023] A through hole is provided in the middle of the screw 2, and a cushion block 5 is provided on the inner side of the claw 3-1. The cushion block 5 can be pressed on the bottom of the connecting hole 6-2. A connecting rod 5-1 is connected above the cushion block 5. A transverse pin hole 5-2 is provided above the connecting rod 5-1. The connecting rod 5-1 passes through the through hole so that the pin hole 5-2 extends above the screw 2, and the plug 1 is inserted into the pin hole 5-2. Before the hook 3 is installed, the cushion block 5 is located above the inner side of the claw 3-1, and the plug hole 5-1 of the connecting rod 5-1 extends above the screw 2, and is fixed by the plug 1 so that the cushion block 5 will not move downward to block the bending of the claw 3-1; after the hook 3 is installed above the screw seat 6, the plug 1 is pulled out so that the cushion block 5 is pressed downward on the bottom of the connecting hole 6-2, limiting the inward bending of the claw 3-1, thereby preventing the hook 3 from loosening from the screw seat 6.

[0024] The top of the cushion block 5 is covered with a spring 4 on the connecting rod 5-1. The cushion block 5 can be pressed on the bottom of the screw seat 6 by the elastic force of the spring 4.

[0025] The cushion block 5 is a magnet, and the screw seat 6 is a ferromagnetic material. The cushion block 5 can be sucked on the bottom of the screw seat 6 by the magnetic force of the magnet.

[0026] There are four claws 3-1 evenly arranged in a ring shape, and gaps 3-4 are provided between adjacent claws 3-1. The gaps 3-4 separate the claws 3-1, making it easier for the claws 3-1 to bend and deform.

[0027] A guide slope 1 3-3 is provided below the boss 3-2, and a guide slope 2 6-4 is provided above the groove 6-3. When the hook 3 moves downward, the guide slope 1 3-3 cooperates with the guide slope 2 6-4 to make the claw 3-1 bend inward, and the claw 3-1 completely enters the boss 3-2 and is stuck in the groove 6-3.

[0028] When the utility model is used, the screw seat 6 is first installed on the threaded hole of the equipment through the stud 6-1. When the equipment is assembled and the sling 7 needs to be installed, the claw 3-1 of the hook 3 that has been assembled with the screw 2 and the sling 7 is inserted into the connecting hole 6-2, and the guide slope 1 3-3 contacts the guide slope 2 6-4. As the hook 3 is pushed in, the claw 3-1 is bent inward, and then the boss 3-2 of the claw 3-1 is stuck in the groove 6-3, and the claw 3-1 is restored to a straight state. During the pushing process, the cushion block 5 is located on the upper inner side of the claw 3-1, and will not affect the bending of the boss 3-2 at the lower end of the claw 3-1.

[0029] After the claw 3-1 is installed in the connecting hole 6-2, the pin 1 in the pin hole 5-2 is pulled out, and the pad 5 is pressed downward on the bottom of the connecting hole 6-2 under the action of the spring 4 or the magnetic force of the magnet, thereby supporting the inner side of the part of the claw 3-1 with the boss 3-2, so that the claw 3-1 cannot be retracted, which can effectively prevent the connection between the hook 3 and the screw seat 6 from loosening and falling off for a long time under various working conditions.
