Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. The technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

Referring to fig. 1 and 2, the utility model discloses a coupler shaft 1, coupler body 2 and mousing-hook piece, coupler body 2 fixed connection is on coupler shaft 1, and the inboard of the neck of coupler body 2 is fixed with lug 3, and mousing-hook piece is including the piece of pressing and dead lever 4 that hangs, and dead lever 4 is rotatable passes lug 3, and the both ends of dead lever 4 are all connected on the piece of pressing that hangs to the drive piece of hanging rotates, makes it can form the enclosure space with coupler body 2 and avoids being hung the product unhook.

The casting die that hangs down includes baffle 5 and the arc 6 of connection in baffle 5 both sides, baffle 5 is located the inboard of coupler body 2, arc 6 sets up the both sides at coupler body 2 relatively, dead lever 4 rotationally wears to establish in lug 3 and both ends connect respectively on the arc 6 of both sides, the other end of arc 6 extends to the coupler body 2 outside, arc 6 is exactly for convex 6 material, the width of arc 6 is played by the one end of being connected with baffle 5 and is reduced gradually, simultaneously the height of the one end that arc 6 and baffle 5 are connected is highly unanimous with baffle 5, so, firstly, arc 6 of baffle 5 is connected inseparabler, no matter be long-time wearing and tearing or continuous rotation, the cracked condition of junction can not appear, another is exactly because the width broad of junction, baffle 5 supports when the inboard confined space that forms of coupler body 2, the confined is firmer more closed, the condition of article slippage can not appear. Meanwhile, due to the special structure of the arc-shaped plate 6, a natural sagging phenomenon exists, and an additional structure of a balancing weight is not needed.

One end of the baffle 5 close to the hook body 2 is provided with an arc-shaped opening 7, and the bending direction of the arc-shaped opening 7 is towards the fixing rod 4. The arc-shaped opening 7 is clamped on the inner wall of the hook body 2, and a closed space is formed between the arc-shaped opening and the hook body 2 better, so that a hung product is prevented from being unhooked.

The baffle is also provided with a through hole 8, so that the phenomenon that the baffle 5 is heavy and light is prevented, and the baffle 5 and the lifting hook are difficult to close.

The drop-pressing piece is of an integrally formed structure, the integrally formed structure is relatively more durable, and meanwhile, the assembly is also convenient.

When the lifting hook works specifically, a product to be lifted presses the baffle 5 downwards through the self gravity, so that the fixed rod 4 rotates in the lifting lug 3, the baffle 5 moves towards the inner side of the hook body 2, the lifting hook opening is opened, the product automatically enters the hook body 2, the arc-shaped plate 6 is slightly pushed, so that the baffle 5 returns to the original position to form a closed space with the hook body 2, and the unhooking prevention effect is realized; when unhooking, people arc 6 on the coupler body 2 back, because lever principle, dead lever 4 is at 3 rotations of lug, and the one end that baffle 5 has arc opening 7 leaves the coupler body 2 inner wall, to the inboard removal of hook portion, and the lifting hook mouth is opened, and the product can break away from coupler body 2.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
