As exemplarily shown in fig. 2, the locking device 100 may further include a sealing gasket 129, the sealing gasket 129 being adapted to be disposed between the bottom surface of the upper portion 114 of the base 102 and the surface of the second member to seal a gap between the locking device 100 and the second member.

Referring to fig. 1B, 6-8, in the illustrated embodiment, the latch 104 is received in the receiving cavity 118 of the base 102 and is adapted to move between a locked position and an unlocked position along the second direction D2. In the illustrated embodiment, the first direction D1 is perpendicular to the second direction D2, and the latch 104 traverses the first channel 108 of the base 102.

The shackle 104 has a first end 132 and a second end 134 in the second direction D2. In the illustrated embodiment, a portion of the shackle 104 between the first end 132 and the second end 134 defines the second channel 110 along the first direction D1. In the illustrated embodiment, the second channel 110 has a generally "concave" cross-section. The body portion 131 of the second channel 110 is adjacent to the latch bolt 112 in the second direction D2. The second channel 110 allows the first member to be inserted from the body portion 131 of the second channel 110 (i.e., the portion adjacent to the latch bolt 112 in the second direction D2). It is understood that the second channel 110 may be designed in other shapes to accommodate differently shaped first members; the second passage 110 may be a circumferentially closed passage as shown, or may be an unclosed passage.

In fig. 1B and 6, the locking device 100 is in an initial state, in which the shackle 104 is in a locked position with the locking tongue 112 extending into the first channel 108. In the illustrated embodiment, the locking tab 112 extends through the first channel 108 in the second direction D2. The shackle 104 may be moved in the second direction D2 until the first channel 108 communicates with the body portion 131 of the second channel 110 in the first direction D1 to allow the first member to be inserted into the body portion 131 of the second channel 110 of the shackle 104 via the first channel 108, i.e., to an unlocked position where the locking bolt 112 is withdrawn from the first channel 108. By positioning the second channel 110 at least partially adjacent to the locking tongue 112 in the second direction D2, it may be achieved that: the switching of the latch 104 between the locked and unlocked positions described above is accomplished by simply moving the latch 104 in the second direction D2.

Referring to fig. 2, the latch bolt 112 may be provided with a guide surface 136, and the guide surface 136 is configured to guide the locker 104 to move toward the unlock position in the second direction D2 when receiving a pressing force in the first direction D1. In the illustrated embodiment, the guide surface 136 is an inclined surface. Alternatively, the guide surface 136 may be a surface having another shape such as a curved surface.

Referring to fig. 2 and 8, the resilient member 106 may be in the form of a coil spring and is positioned between the catch 104 and the upper portion 114 of the base 102 in the second direction D2. The first end 120 of the upper portion 114 of the base 102 may be provided with a first detent 138, the latch 104 may be provided with a second detent 140 aligned with the first detent 138 in the second direction D2, and both ends of the coil spring 106 may be respectively engaged with the first detent 138 and the second detent 140 to position the resilient member 106 between the latch 104 and the upper portion 114 of the base 102 in the second direction D2. In the illustrated embodiment, the first positioning portion 138 is in the form of a concave hole, the second positioning portion 140 is in the form of a convex pillar, and both the concave hole 138 and the convex pillar 140 extend along the second direction D2. Alternatively, as exemplarily shown, the locking device 100 comprises two coil springs 106, the base 102 is symmetrically provided with two concave holes 138 in a direction perpendicular to both the first direction D1 and the second direction D2, and the lock catch 104 is symmetrically provided with two convex posts 140, respectively. It is understood that a boss may be disposed on the base 102 and a corresponding recess may be disposed on the latch 104; alternatively, both the base 102 and the latch 104 may be provided with posts or recesses.

In the illustrated embodiment, the second end 122 of the upper portion 114 of the base 102 can be provided with a first retaining portion 142 and the second end 134 of the catch 104 can be provided with a second retaining portion 144. The second retaining portion 144 of the latch 104 is adapted to abut the first retaining portion 142 of the base 102 under the biasing action of the coil spring 106 on the latch 104 to retain the latch 104 in the locked position. In the illustrated embodiment, the first retaining portion 142 may be in the form of a channel, the channel 142 extending along the second direction D2, and the second retaining portion 144 is in the form of a tab, the tab 144 adapted to mate with the channel 142.

Optionally, as schematically shown in fig. 8, the first end 132 of the shackle 104 may be provided with a pressing portion 146 to apply a biasing force in the second direction D2 to the shackle 104 to move the shackle 104 from the locked position to the unlocked position in the second direction D2.

The use of the locking device 100 according to an exemplary embodiment of the present invention is explained below with reference to fig. 1A to 8, taking as an example a first member for locking in the form of a U-shaped locking ring.

Referring to fig. 1B and 6, in the initial state of the locking device 100, the shackle 104 is in the locked position and the locking tongue 112 of the shackle 104 extends into the first channel 108. At this point, the U-shaped locking ring may be inserted into the locking device 100 via the first channel 108 in a first direction D1. During insertion, the U-shaped locking ring applies a biasing force to the guide surface 136 of the locking bolt 112, thereby guiding the shackle 104 to move in the second direction D2 to an unlocked position where the first channel 108 is in communication with the body portion 131 of the second channel 110. At this point, the shackle may be inserted into the body portion 131 of the second passage 110, and as the shackle is further inserted until the U-shaped opening of the shackle is aligned with the locking tab 112 in the second direction D2 such that the shackle no longer pushes against the locking tab 112, the shackle 104 may be moved toward the locked position under the bias of the coil spring 106 until the locking tab 112 re-extends into the first passage 108 (i.e., the locking tab 112 is inserted into the U-shaped opening of the shackle) to stop the shackle, preventing the shackle from moving away from the lock assembly 100 via the first passage 108, thereby locking the shackle. It should be appreciated that in the above process, instead of inserting the shackle to move the shackle 104 to the unlocked position, the pressing portion 146 of the shackle 104 is directly pressed to move the shackle 104 to the unlocked position before inserting the shackle.

When it is desired to unlock the U-shaped lock ring, the pressing portion 146 of the shackle 104 may be pressed to move the shackle 104 in the second direction D2 to an unlocked position where the first channel 108 communicates with the main body portion 131 of the second channel 110 (at which time the locking tongue 112 is also withdrawn from the U-shaped hole of the U-shaped lock ring following the movement of the shackle 104 to no longer stop the U-shaped lock ring), and then the U-shaped lock ring may be pulled out through the first channel 108 to unlock the U-shaped lock ring.

The application of the locking device according to the present invention has been described above only by way of example of the use of the locking device 100 according to an exemplary embodiment for locking a U-shaped locking ring. It will be appreciated that the locking device according to the invention may be used to lock other shaped members, such as L-shaped members, in which case the locking tongue 112 stops against the horizontal portion of the L-shaped member in the locked position.

It should be understood that the embodiments shown in fig. 1A to 8 only show the shape, size and arrangement of the various optional components of the locking device according to the present invention, however, they are merely illustrative and not restrictive, and that other shapes, sizes and arrangements may be adopted without departing from the spirit and scope of the present invention.

The technical content and technical features of the present invention have been disclosed above, but it should be understood that various changes and modifications of the concept disclosed above can be made by those skilled in the art under the inventive concept of the present invention, and all fall within the scope of the present invention. The above description of embodiments is intended to be illustrative, and not restrictive, and the scope of the invention is defined by the appended claims.
