Fig. 2 corresponds to a cross-sectional view taken along a dashed line A1-A2 shown in fig. 1, and fig. 3 and 4 are exploded perspective views from different angles. As shown in the embodiment of fig. 2, the latch hook device 200 includes a housing 210, a latch hook 220, and a latch hook spring 217. The housing 210 is disposed on the base 110, an arc-shaped groove 216 is disposed in the housing 210, and the latch hook 220 is movably disposed in the arc-shaped groove 216. As shown in fig. 3 and 4, one end of the latch hook 220 is provided with a hook portion 221, and a latch hook elastic member 217 is disposed in the arc-shaped groove 216 (see fig. 2), so as to provide an elastic force to move the latch hook 220 along the arc-shaped groove 216 until the hook portion 221 protrudes out of the housing 210. The first lock core 400 is disposed on the base 110. Wherein, when the first lock core 400 is in the locked state, the movement of the lock hook 220 is restricted; when the first lock core 400 is in the unlocked state, the lock hook 220 can move along the arc-shaped slot 216.

More specifically, as shown in the embodiment of fig. 3 and 4, the lock device 900 further includes a first moving member 300 disposed at one side of the latch hook device 200. The housing 210 includes a housing side 212 and a housing top 213, the housing side 212 is provided with a driving hole 214, and the housing top 213 is provided with a locking hole 215. A latch hook driving portion 222 is disposed at a side of the latch hook 220, and the latch hook driving portion 222 extends out of the housing side 212 through the driving hole 214. The latch hook elastic member 217 provides an elastic force to move the latch hook 220 along the arc-shaped groove 216 until the hook portion 221 protrudes out of the housing 210 and enters the latch hook hole 215.

In one embodiment, the housing side surface 212 and the housing top surface 213 are preferably vertical, in other words, the housing side surface 212 and the housing top surface 213 face to the second direction 702 and the third direction 703 respectively, and the first direction 701, the second direction 702 and the third direction 703 are orthogonal.

One end of the arc-shaped groove 216 is closed, the other end is an opening communicated with the locking hook hole 215, and the locking hook elastic member 217 is located between the closed end of the arc-shaped groove 216 and the locking hook. The first moving member 300 is disposed at one side of the latch hook device 200.

Wherein, when the first lock core 400 is in a locked state, the movement of the first moving member 300 is restricted; when the first lock core 400 is in the unlocked state, the first moving member 300 can be forced to move toward the first direction 701, so as to drive the lock hook driving portion 222 to drive the lock hook 220 to move along the arc-shaped groove 216, so that the hook portion 221 leaves the lock hook hole 215 and enters the housing 210.

More specifically, in the embodiment shown in fig. 3 to 4, the first lock cylinder 400 is a combination lock cylinder including a lock shaft rod 310 connected to the first moving member 300. When the character wheel of the first lock core 400 rotates to the non-unlocking position, the first lock core 400 is in a locking state, and the movement of the lock shaft rod 310 is limited, so that the movement of the first moving part 300 is limited; when the print wheel of the first lock core 400 rotates to the unlock position, the first lock core 400 is in the unlock state, and the lock shaft rod 310 can move along the first direction 701. However, in various embodiments, the first lock core 400 is not limited to a combination lock core, and is not limited to restricting the movement of the first moving member 300 by restricting the movement of the lock shaft 310.

As shown in the embodiments of fig. 3 to 4, the lock 900 further includes a first elastic member 710, and the first elastic member 710 is disposed between the base 110 and the first moving member 300. Further, the character wheel of the first lock core 400 is disposed on the base 110, one end of the lock shaft rod 310 of the first moving member 300 adjacent to the lock hook device 200 is disposed with a protrusion 304, and the first elastic member 710 is disposed between the protrusion 304 and the adjacent character wheel. When the first moving member 300 and the locking shaft rod 310 move toward the first direction 701, the first elastic member 710 provides a return elastic force to the first moving member 300 opposite to the first direction 701. On the other hand, the base 110 further includes a limiting portion 104 disposed on the other side of the protrusion 304 opposite to the first elastic member 710 for limiting the movement of the locking shaft 310 toward the locking hook device 200.

As shown in the embodiment of fig. 3 to 4, the lock device 900 further includes a second moving member 600, the second moving member 600 is disposed on the other side of the latch hook device 200 on the base 110 opposite to the first moving member 300, the first moving member 300 and the second moving member 600 respectively have a first driving portion 330 and a second driving portion 610 which can abut against each other, and the second moving member 600 includes a third driving portion 620. The third driving portion 620 is preferably a slope. The lock 900 further includes a second elastic member 720, the second elastic member 720 is disposed between the latch hook device 200 and the second moving member 600, and when the second moving member 600 moves toward the first direction 701, the second elastic member 720 provides a restoring elastic force to the second moving member 600 opposite to the first direction 701.

The operation of the lock of the present invention is further described below.

Fig. 5A is a perspective view of an embodiment of the present invention, fig. 5B corresponds to a plan view of fig. 5A, fig. 5C corresponds to a sectional view taken along a broken line B1-B2 shown in fig. 5B, and fig. 5D corresponds to a sectional view taken along a broken line C1-C2 shown in fig. 5B. As shown in fig. 5A to 5D, the latch hook elastic member 217 disposed in the arc-shaped groove 216 (see fig. 2) provides an elastic force to make the hook portion 221 enter the latch hook hole 215, and an object to be locked (not shown), such as a zipper head, is restricted from leaving by the hook portion 221 when inserted into the latch hook hole 215. When the first lock core 400 is in the locked state, the movement of the lock shaft rod 310 is restricted, and the movement of the first moving member 300 is restricted, so that the user cannot move the first moving member 300 even if applying a force thereto, and the release hook 221 cannot restrict the object to be locked from leaving the lock hook hole 215.

Fig. 6A is a perspective view of an embodiment of the present invention, fig. 6B corresponds to a plan view of fig. 6A, fig. 6C corresponds to a cross-sectional view taken along a broken line D1-D2 shown in fig. 6B, and fig. 6D corresponds to a cross-sectional view taken along a broken line E1-E2 shown in fig. 6B. As shown in fig. 6A to 6D, when the first lock core 400 is in the unlocked state, a user can apply a force to the force-receiving portion 320 of the first moving member 300, for example, to move the first moving member 300 toward the first direction 701. At this time, the first driving portion 330 abuts against the second driving portion 610 (see fig. 3) and drives the second moving member 600 to move in the first direction 701, so that the third driving portion 620 abuts against the locking hook driving portion 222 and drives the locking hook 220 to move along the arc-shaped groove 216, the hook portion 221 leaves the locking hook hole 215 and enters the housing 210, and the restriction of the locked object leaving the locking hook hole 215 by the hook portion 221 is released.

On the other hand, when the user stops applying the force to the first moving part 300, the locking hook elastic element 217, the first elastic element 710 and the second elastic element 720 respectively provide elastic force to allow the first moving part 300, the second moving part 600 and the locking hook 220 to return to the positions shown in fig. 5A to 5D. However, in different embodiments, even if the first elastic element 710 and the second elastic element 720 are not disposed, the latch hook elastic element 217 can still drive the latch hook driving portion 222 to move, and further push the third driving portion 620 to drive the second moving element 600, and then the second moving element 600 drives the first moving element 300. In addition, in different embodiments, the first moving member 300 can directly drive the locking hook driving portion 222 to drive the locking hook 220 to move along the arc-shaped groove 216 through other mechanism designs such as an inclined surface similar to the third driving portion 620, which omits the second moving member 600 and simplifies the structure of the lock device 900.

Compared with the conventional lock hook which moves linearly, in the lock 900 of the present invention, the lock hook 220 moves in a curve in the arc-shaped groove 216, the moving stroke is long, and the lock hook substantially contacts the arc-shaped groove 216 in multiple directions, so that accidental opening due to collision and other factors is less likely to occur.

As shown in fig. 3 and 4, the lock 900 further includes a second lock cylinder 500, and the second lock cylinder 500 is disposed on the other side of the second moving member 600 on the base 110 opposite to the latch hook device 200. In the embodiment shown in fig. 7A to 7B, the bottom end of the second lock cylinder 500 is provided with a rotary driving member 520. Fig. 7A and 7B are schematic diagrams of the embodiment shown in fig. 5A from different viewing angles, that is, when the rotary driving element 520 is located at the position shown in fig. 7A and 7B, the hook portion 221 enters the locking hole 215. As shown in fig. 8A and 8B, when the second lock cylinder 500 is in the unlocked state, the rotary driving element 520 can rotate to make the end 521 abut against the second moving element 600, so as to drive the second moving element 600 to move in the first direction 701, so that the third driving element 620 abuts against the latch hook driving element 222 and drives the latch hook 220 (see fig. 2) to move along the arc-shaped slot 216, so that the hook portion 221 leaves the latch hook hole 215 and enters the housing 210. Wherein, one side 630 of the second moving member 600 opposite to the second lock core 500 is arc-shaped, so that the rotation of the rotary driving member 520 is more easily abutted to the second moving member 600.

Further, with the above arrangement, the lock device 900 of the present invention can unlock the second lock cylinder 500 and separate the hook portion 221 from the hook hole 215 when the first lock cylinder 400 is in the locked state, that is, the lock device can be unlocked by using the second lock cylinder 500 without unlocking the first lock cylinder 400. The second lock core 500 is preferably a lock core approved by the U.S. transportation security agency, customs, or other law enforcement agencies that can use a dedicated key to unlock the second lock core 500, thereby facilitating and improving inspection efficiency.

It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Numerous obvious variations, adaptations and substitutions will occur to those skilled in the art without departing from the scope of the invention. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
