Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

The hanging ring lock for angle steel galvanization hanging shown in the reference figures 1 to 7 mainly comprises a U-shaped lock body 1 and lock pins 2, wherein the U-shaped lock body 1 is of a U-shaped structure as a whole and comprises a circular tube section 10 in a U shape and flat parts 11 positioned at two ends of the circular tube section 10, the flat parts 11 are in a strip-shaped flat plate shape, through holes 13 for the lock pins 2 to pass through are formed in positions, close to the lower ends, of the flat parts 11, in general, in order to reduce processing cost, the U-shaped lock body 1 is formed by welding the circular tube section 10 and the flat parts 11, the flat parts 11 are made of steel plates, and are relatively easy to obtain in an iron tower production workshop.

In this application, the middle part inboard of the pipe section 10 of U-shaped has hoist spacing groove 12, and hoist spacing groove 12 is arc structure, and when the crane hook was lived U-shaped lock body 1 like this, fall into hoist spacing groove 12 more easily, avoid sliding, the position that corresponds hoist spacing groove 12 on the lockpin 2 has angle steel spacing groove 20, angle steel spacing groove 20 is waist shape annular structure, no matter what position is rotated to lockpin 2 like this, angle steel also falls into angle steel spacing inslot 20 easily to avoid rocking about the angle steel.

In particular, in order to facilitate the quick insertion and extraction of the lock pin 2, one end of the lock pin 2 is tapered, and the other end has a pull-out buckle 21. Meanwhile, the eccentric part 22 is arranged at one end of the lock pin 2 far away from the pull-out buckle 21, the eccentric part 22 is positioned at the outer side of the circumference of the lock pin 2, the abdication part 130 which is matched with the eccentric part 22 is arranged at the upper side of the through hole 13, the abdication part 130 is communicated with the through hole 13 and is positioned right above the through hole 13 in implementation, so that when the lock pin 2 passes through the through hole 13, the lock pin 2 is misplaced relative to the abdication part 130 by slightly rotating, and is difficult to automatically withdraw from the through hole 13, and the lock pin 2 can be rotated more easily by the existence of the eccentric part 22 and is misplaced with the abdication part 130, thereby ensuring the reliability of the lock pin 2.

In this embodiment, the pull-out buckle 21 has a substantially polygonal structure and is in a uniform plane with the eccentric portion 22, which is advantageous in ensuring the reliability of the eccentric rotation.

As shown in the figure, the eccentric portion 22 extends along the length direction of the lock pin 2, one end of the eccentric portion, which is far away from the pull-out buckle 21, is arc-shaped, and the other end of the eccentric portion is a flat surface which is arranged along the radial direction of the lock pin 2, so that the lock pin 2 is relatively easier to insert, the retraction difficulty is increased, the eccentric portion can be retracted only when the rear end of the lock pin 2 is aligned with the abdicating portion 130, and the lifting safety is greatly improved.

In order to improve the overall safety and reduce the abrasion of the diagonal steel surface, the edges of the inner side of the flat part 11 are provided with arc-shaped fillets, and the lower end of the flat part 11 is also arc-shaped.

Referring to the ring lock for galvanized lifting of angle steel shown in fig. 1 to 7, when in use, the U-shaped lock body 1 is clamped to two sides of the angle steel, the through holes 13 are opposite to the connecting holes on the angle steel, then the lock pins 2 are utilized to rotate after the through holes 13 are inserted, the eccentric parts 22 are downward, at the moment, the lifting hooks hook the U-shaped lock body 1, the lifting hooks can easily enter the lifting tool limiting grooves 12, and the angle steel corresponding connecting holes can slide into the angle steel limiting grooves 20, so that relative sliding between every two angle steel limiting grooves is avoided in the subsequent moving process.

Finally, it should be noted that the above description is only a preferred embodiment of the present utility model, and that many similar changes can be made by those skilled in the art without departing from the spirit and scope of the utility model as defined in the appended claims.
