Description

A waterproof hook assembly

Technical Field

The utility model relates to the technical field of waterproof hook groups, in particular to a waterproof hook group.

Background Art

The hook pulley block is a simple machine assembled from movable pulleys, which can save effort and change the direction of force.

When the existing hook pulley block works on rainy days, since the hook pulley block has no shielding, rain will directly fall on the bearing of the hook pulley block. After the rain stops, the ball and inner wall of the bearing will rust after oxidation in the air, thereby affecting the normal use of the hook pulley block.

A hook pulley block with a waterproof function disclosed in the Chinese utility model patent application disclosure CN210736073U, although the hook pulley block with a waterproof function has the advantages of shielding rainwater and increasing the stability of use, the hook pulley block with a waterproof function still has disadvantages: first, the hook pulley block with a waterproof function requires manual hanging of the rope on the hook before it can be used, but in actual use, the position of the entire hook block is fixed, so if it is encountered that the length of some ropes is not enough and the objects to be hoisted are too heavy, it may be inconvenient to manually hang the rope on the hook; second, the hook and the connecting rod on the hook pulley block with a waterproof function are integrated, so in actual use, if it is necessary to replace hooks of different sizes, the entire block needs to be replaced, so the efficiency during use may not be very high, and since the hooks are often located at high places, it is not very convenient to replace them.
