Referring to fig. 1 to 4, fig. 1 is a front view of an automatically unlockable hook of a first embodiment, fig. 2 is a right side view of fig. 1, fig. 3 is a sectional view taken along a-a section of fig. 2, and fig. 4 is an exploded view of the automatically unlockable hook of fig. 1. The automatic unlocking hook of the present embodiment includes a movable arm 100, a fixed arm 200, a rotation shaft 300, an elastic element 400, and an end cap 500, wherein the lower end of the movable arm 100 is a first end thereof (refer to fig. 1), the upper end of the fixed arm 200 is a second end thereof (refer to fig. 1), similarly, the lower end of the fixed arm 200 is a first end thereof (refer to fig. 1), the upper end of the fixed arm 200 is a second end thereof (refer to fig. 1), the second end of the movable arm 100 is rotatably connected to the second end of the fixed arm 200, the movable arm 100 is capable of rotating around a front-rear axis with respect to the fixed arm 200, the movable arm 100 is capable of moving up and down with respect to the fixed arm 200, the movable arm 100 is overall in a "V" shape, the fixed arm 200 is in a long strip shape, after the first end of the movable arm 100 is locked to the first end of the fixed arm 200, the movable arm 100 and the fixed arm 200 form a closed loop, after the movable arm 100 rotates clockwise (referring to fig. 1, that is, the second direction is clockwise) relative to the fixed arm 200, the hook is opened, and the article can be put down.

In order to lock the first end of the movable arm 100 and the first end of the fixed arm 200, the first end of the fixed arm 200 is provided with a locking hole 240, a lower end surface of the locking hole 240 is an inclined surface (see fig. 3), a clamping groove is formed on the inclined surface, a surface of the clamping groove, which tends to be horizontal, is a first abutting surface 241, correspondingly, a boss 110 (see fig. 3) is arranged on the lower side of the first end of the movable arm 100, and a second abutting surface 111 is arranged on the lower left side of the boss 110.

After the first end of the movable arm 100 extends into the lock hole 240, the boss 110 can be clamped into the clamp groove, when the first abutting surface 241 abuts against the second abutting surface 111, the movable arm 100 cannot rotate relative to the fixed arm 200, and when the movable arm 100 needs to rotate relative to the fixed arm 200 in the clockwise direction, the movable arm 100 needs to move upwards, after the first abutting surface 241 and the second abutting surface 111 are disengaged from the abutting, the first end of the movable arm 100 is disengaged from the lock hole 240, the movable arm 100 rotates relative to the fixed arm 200 in the clockwise direction, and the hook is opened.

Therefore, by hanging the article on the movable arm 100, due to the gravity of the article, the first abutting surface 241 and the second abutting surface 111 can be kept abutting, that is, the movable arm 100 moves along the first direction relative to the fixed arm 200, that is, the movable arm 100 moves along the downward direction relative to the fixed arm 200, and when the hook needs to be unlocked, the movable arm 100 moves along the direction opposite to the first direction relative to the fixed arm 200, that is, the movable arm 100 moves along the upward direction relative to the fixed arm 200.

In order to realize the rotational connection between the second end of the movable arm 100 and the second end of the fixed arm 200 and to enable the movable arm 100 to move in the vertical direction with respect to the fixed arm 200, a waist-shaped hole 220 is formed at the first end of the fixed arm 200, the length direction of the waist-shaped hole 220 is arranged in the vertical direction, and correspondingly, a rotating shaft 300 is fixed to the movable arm 100, and after the rotating shaft 300 passes through the waist-shaped hole 220, the movable arm 100 can rotate around the shaft in the front-back direction (refer to fig. 1) and can also move in the vertical direction (refer to fig. 1) with respect to the fixed arm 200.

In this embodiment, the rotating shaft 300 is a screw, the second end of the movable arm 100 is provided with a connecting groove 130, after the second end of the fixed arm 200 is placed in the connecting groove 130, the screw passes through the through hole 120 and the kidney-shaped hole 220 in sequence, and then is screwed and fixed with the movable arm 100.

In another embodiment, the waist-shaped hole 220 may be replaced by an arc-shaped hole, and the arc-shaped hole may also realize the rotational connection between the second end of the movable arm 100 and the second end of the fixed arm 200, and simultaneously enable the movable arm 100 to move in the up-and-down direction relative to the fixed arm 200.

In order to allow the movable arm 100 to automatically rotate clockwise (refer to fig. 1) with respect to the fixed arm 200 when the article is separated from the working surface 160 of the movable arm 100 after the article is landed, an elastic member 400 is provided, in the embodiment, the elastic element 400 is a torsion spring, the torsion spring is sleeved on the rotating shaft 300, a first end of the torsion spring abuts against the fixed arm 200, a second end of the torsion spring abuts against the movable arm 100, when the first end of the movable arm 100 extends into the lock hole 240, the torsion spring is in a deformed state, and when the article is disengaged from the working surface 160 of the movable arm 100, the torsion spring drives the movable arm 100 to rotate clockwise relative to the fixed arm 200, meanwhile, the boss 110 slides out of the clamping groove, the movable arm 100 slides upwards relative to the fixed arm 200, the second abutting surface 111 is separated from the first abutting surface 241, unlocking of the movable arm 100 and the fixed arm 200 is finally achieved, and a closed ring formed by the movable arm 100 and the fixed arm 200 is opened.

In order to facilitate the installation of the torsion spring, the second end of the fixed arm 200 is provided with the accommodating groove 230, after the torsion spring is placed in the accommodating groove 230, the first end of the torsion spring is firstly abutted against the fixed arm 200 (the first end of the torsion spring is inserted into the blind hole through the blind hole formed in the fixed arm 200, so that the first end of the torsion spring is abutted against the fixed arm 200), meanwhile, the second end of the movable arm 100 is provided with the positioning hole 140, the orthographic projection of the inner surface 141 at the front side of the positioning hole 140 is a regular hexagon, correspondingly, the orthographic projection of the outer contour surface of the end cover 500 is also a regular hexagon, after the end cover 500 is embedded into the positioning hole 140, the second end of the torsion spring is abutted against the end cover 500 (the second end of the torsion spring is abutted against the end cover 500 through the blind hole formed in the end cover 500.

Because the end cap 500 and the positioning hole 140 are regular hexagons matched with each other, the angle of the end cap 500 embedded into the positioning hole 140 can be conveniently adjusted, and the blind hole in the end cap 500 and the second end of the torsion spring can be conveniently inserted in an aligned manner. The end cap 500 is detachably fixed to the movable arm 100, so that the torsion spring can be conveniently installed and fixed.

In other embodiments, the orthographic projection of the interior surface 141 of the front side of the locating aperture 140 and the orthographic projection of the outer contoured surface of the end cap 500 can be other regular polygons, such as an equilateral triangle and a positive direction.

In another embodiment, the end cap 500 may be locked to the movable arm 100 by screws, so as to detachably fix the end cap 500.

In another embodiment, the elastic element 400 may also be a compression spring, that is, an arc-shaped blind hole is formed on the second end of the movable arm 100, and the compression spring is placed in the arc-shaped blind hole, and when the first end of the movable arm 100 extends into the lock hole 240, the compression spring is in a compressed state, so that the movable arm 100 automatically rotates in a clockwise direction relative to the fixed arm 200.

Referring to fig. 2 and 3, in order to prevent the first end of the movable arm 100 from excessively protruding from the locking hole 240, a first clamping point 150 is disposed at the second end of the movable arm 100, a second clamping point 250 is disposed at the second end of the fixed arm 200, and when the protrusion 110 is disposed in the clamping groove, the first clamping point 150 and the second clamping point 250 abut against each other.
