[0006] The bracket has a mounting plate connected to the surface of the bracket and a hook is connected to the center of the bottom of the mounting plate through a rotating shaft. A movable groove is provided in the bottom of the hook, and an arc block is slidably connected in the movable groove. A closing component is provided on the surface of the hook to prevent the rope from slipping out of the hook. The sliding rod of the closing component is inserted into the slot provided on the surface of the hook so that the sliding rod closes the opening of the hook.
[0007] Preferably, the closing assembly includes a sleeve and a first spring, a short block is connected to the surface of the hook and one end of the sleeve is rotatably connected to the surface of the short block, and the sliding rod is slidably connected in the sleeve.
[0008] Preferably, the first spring is arranged in the sleeve and the two ends of the first spring are respectively connected to the sleeve and the sliding rod. A sliding block is connected to the surface of the sliding rod and one end of the sliding block moves through the sliding groove on the surface of the sleeve.
[0009] Preferably, both ends of the arc block are connected to guide blocks, two groups of guide grooves are provided in the hook, and the arc block is slidably connected to the two groups of guide grooves through the guide blocks on both sides.
[0010] Preferably, a plurality of guide rods are connected to the bottom of the arc block and the other end of the guide rod slides through a fixed groove provided in the hook, a second spring is sleeved on the surface of the guide rod and the two ends of the second spring are respectively connected to the arc block and the hook.
[0011] Preferably, a protective pad is provided on the top surface of the arc-shaped block.
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] (1) By sliding the slider on the surface of the slide rod, the slider slides in the slide groove and drives the slide rod to move into the sleeve and compress the first spring, so that the slide rod is disengaged from the slot, and the opening of the hook is opened, and then the rope for binding the object can be hooked through the hook, and then the slider is released. The first spring rebounds and drives the slide rod to move to one end close to the slot and inserts it into the slot, so that the opening of the hook is closed by the slide rod to prevent the rope from falling off from the hook due to shaking and other factors during the lifting process, thereby greatly increasing the safety of the hook during lifting operation.
[0014] (2) When the hook hooks up the rope and makes the rope contact with the arc block, the rope will squeeze the arc block to move into the movable groove and compress the second spring, so that when the hook hooks the object, it can buffer the impact force it bears and absorb the vibration energy during hooking, prevent the hook from resonating, and increase the stability during lifting. When the hook hooks up the rope, the rope contacts the rubber protective pad on the surface of the arc block when it is tightened in the hook. The soft surface of the rubber protective pad can make the rope slide on it more smoothly, reducing the noise caused by friction. BRIEF DESCRIPTION OF THE DRAWINGS
