In addition, when the self-locking hook is used, the spring elasticity needs to be overcome when the lock tongue is pushed open, so that the lock tongue needs to be pushed open by a worker with force, and fatigue can be caused if the self-locking hook is operated frequently for a long time. The utility model provides a self-locking hook which can be used for quickly hoisting and taking out objects, effectively saving labor force and improving assembly efficiency.

Next, referring to fig. 1, the self-locking hook provided by the present invention will be described in detail.

The self-locking hook disclosed by the embodiment of the utility model comprises a hook body 100 and a lock tongue 200; the hook body 100 comprises a first part 101 and a second part 102 which are sequentially connected along the length direction of the hook body 100, wherein the first part 101 is used for being installed on an external member, and the second part 102 is used for hoisting an object to be hung.

Specifically, the external member is a mechanism for installing a self-locking hook, and can be a suspension bracket on a transportation mechanism and the like.

The length direction of the hook body 100 is a vertical direction of the hook body 100 shown in fig. 1, i.e., a direction indicated by H.

Further, the first portion 101 and the second portion 102 of the hook body 100 may be integrally formed, welded or screwed, which is not particularly limited in this embodiment.

According to another specific embodiment of the present invention, as shown in fig. 1, in the self-locking hook disclosed in the embodiment of the present invention, the hook body 100 is in an L-shaped structure, a vertical section of the L-shaped structure, i.e. the H direction shown in fig. 1, is used as a first portion 101 of the hook body 100, a horizontal section of the L-shaped structure is used as a second portion 102 of the hook body 100, and a limiting portion 103 for limiting an object to be hung to be separated from the second portion 102 is disposed at an end of the second portion 102 away from the first portion 101.

Specifically, the extending direction of the vertical section of the L-shaped structure is parallel to the length direction of the hook body 100.

Further, the hook body 100 is used for hoisting objects, and besides the L-shaped structure disclosed by the utility model, the place where the first part 101 is connected with the second part 102 can be set into a circular arc shape, so that transition is facilitated; it is also possible that the first part 101 is vertical and the second part 102 is a hook with a curvature to facilitate lifting of the object.

According to another embodiment of the present invention, as shown in fig. 1, in the self-locking hook disclosed in the embodiment of the present invention, the limiting portion 103 extends vertically upward from the end of the second portion 102 toward a direction away from the second portion 102, and the limiting portion 103 is perpendicular to the second portion 102.

Specifically, the direction away from the second portion 102 is the upward direction of the second portion 102 as shown in fig. 1.

In order to prevent the object lifted on the hook 100 from falling off due to shaking during transportation, the second portion 102 of the hook 100 is provided with the limiting portion 103, and the limiting portion 103 may be set to be perpendicular to the second portion 102 as shown in fig. 1, may also be set to have a certain angle with the second portion 102, or may also be set to be circular arc with the second portion 102, which is not limited in this embodiment.

One end 201 of the latch tongue 200 is slidably connected with the first part 101 of the hook body 100, so that the latch tongue 200 can slide relative to the hook body 100 along the length direction of the first part 101 and can be switched between a first position and a second position; and the number of the first and second electrodes,

when the bolt 200 slides to a first position relative to the hook body 100, the other end 202 of the bolt 200 abuts against the second part 102 of the hook body 100, and an accommodating space for an object to be hung is formed by the bolt 200 and the hook body 100;

when the locking tongue 200 slides to a second position relative to the hook body 100, a gap is formed between the other end 202 of the locking tongue 200 and the second part 102 of the hook body 100, and the gap is used for an object to be hung to pass through and enter the accommodating space so as to be hung on the second part 102 of the hook body 100;

when the latch tongue 200 receives an external force, the latch tongue 200 can slide from the first position to the second position relative to the hook 100, and when the external force is removed, the latch tongue 200 can slide from the second position to the first position relative to the hook 100 under the action of gravity.

Specifically, when the lock tongue 200 is at the first position, the self-locking hook is in a locking state, and at the moment, a hoisting object is hoisted in the accommodating space and can move along with the movement of the self-locking hook. As shown in fig. 1, the accommodating space is an area within a rectangular frame. When the locking tongue 200 is in the second position, the hoisted object can pass through the gap formed between the other end 202 of the locking tongue 200 and the second portion 102 of the hook 100, and be hoisted on the hook 100. When the hoisted object needs to be removed, a gap needs to be formed between the other end 202 of the lock tongue 200 and the second part 102 of the hook body 100 so that the hoisted object can be removed. It should be noted that the second position is not a fixed position, but is a position where the latch 200 is lifted by an external force and slides upwards in the length direction of the hook 100 shown in fig. 1 relative to the first part 101 of the hook 100, as long as the latch slides to a gap formed with the hook 100 for an object to be hoisted to pass through. The object to be lifted differs, and the second position also differs with respect to the position in the longitudinal direction of the hook 100, and this embodiment does not specifically limit this.

By adopting the scheme, one end of the self-locking hook lock tongue 200 is in sliding connection with the first part 101 of the hook body 100, when an object needs to be lifted, a gap for the object to be hung to pass through can be formed between the lock tongue 200 and the hook body 100 only by applying an external acting force to the lock tongue 200, so that the object to be hung is hung on the hook body 100; then, the latch tongue 200 can contact with the hook body 100 under the action of gravity only by canceling the external acting force; when the object to be hung needs to be taken down from the hook body 100, the object can be taken down only by applying an external force to the latch bolt 200 to lift the latch bolt 200. Therefore, in the process of frequently moving objects in vehicle assembly, the spring structure of the self-locking hook cannot be damaged due to overlong service time, when the objects hung on the hook body are taken down, a worker does not need to push the spring bolt open forcibly, the bolt 200 can be lifted by only one hand, the objects are taken out quickly, the labor force is effectively saved, and the assembly efficiency is improved.
