[0045] Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings. These drawings show representative embodiments of the present invention and are not intended to limit the present invention.

[0046] The utility model provides a latch lock.

[0047] See also Figure 1 and Figure 2 , the latch lock 1 may include a lock body 11 and a lock core 12. Specifically, the lock body 11 has an accommodating cavity 11a inside, and the lock core 12 is movably disposed in the accommodating cavity 11a between an extended position and a retracted position along a first direction D1. The end of the lock core 12 away from the lock body 11 has a contact surface 122a inclined relative to the first direction D1, and the contact surface 122a of the lock core 12 in the extended position is at least partially located outside the accommodating cavity 11a. It should be noted that the contact surface 122a is used to receive force to move the lock core 12 toward the retracted position, and the lock core 12 is configured to be rotatable around the first direction D1 to change the orientation of the contact surface 122a.

[0048] According to the latch lock 1 of the present invention, the direction of the inclined contact surface 122a of the lock core 12 can be changed by rotating the lock core 12, so that it is easy to collide with the locked part and retract. There is no need to always lift the latch lock 1, which is convenient for locking and unlocking.

[0049] It should be noted that the first direction D1 may be a horizontal direction or a vertical direction. Figure 1 and Figure 2 In the embodiment, the first direction D1 is configured as a vertical direction.

[0050] For further information, see Figures 1 to 3 The locked member is configured as a trailer 2, which includes a vehicle body 21 and a loading member 22. The latch lock 1 is connected to the vehicle body 21 so that the loading member 22 is locked or separated from the vehicle body 21. It can be understood that the loading member 22 is used to carry goods, and the loading member 22 is detachably connected to the vehicle body 21. Specifically, the latch lock 1 also includes a mounting member 14, which is connected to the lock body 11, for example Figure 3 In the embodiment, the mounting member 14 is detachably connected to the vehicle body 21 via the fastener 3 .

[0051] See also Figure 4 and Figure 5 , the accommodating cavity 11a has a first limiting surface 11c perpendicular to the first direction D1, and the lock core 12 has a second limiting surface 122b perpendicular to the first direction D1, and the first limiting surface 11c and the second limiting surface 122b are spaced apart along the first direction D1. The lock core 12 also includes an elastic member 15, which is sleeved to the outer periphery of the lock core 12 and is located between the first limiting surface 11c and the second limiting surface 122b, so as to drive the lock core 12 to move to the extended position along the first direction D1. Specifically, the lock core 12 includes a lock core body 121 and a lock tongue 122, the lock core body 121 extends along the first direction D1, and the elastic member 15 can be constructed as a spring and is located at the outer periphery of the lock core body 121. The lock tongue 122 is connected to the lock core body 121, and the contact surface 122a is located at the lock tongue 122. It should be noted that, along the second direction D2 perpendicular to the first direction D1 , the lock tongue 122 protrudes outward from the lock core body 121 to form a second limiting surface 122 b.

[0052] Please continue reading Figure 4 and Figure 5 The lock core body 121 and the lock tongue 122 are integrally formed. In an embodiment not shown, the lock core body 121 is configured to be rotatable around the first direction D1, and the lock tongue 122 is movably connected to the lock core body 121 between an extended position and a retracted position along the first direction D1. It is easy to imagine that in order to facilitate the overall pulling and adjustment of the lock core 12, the lock core body 121 can be configured to be movable and adjustable along the first direction D1 on the basis of being rotatable around the first direction D1.

[0053] See also Figures 4 to 6, the latch lock 1 also includes a handle 13, which extends along the second direction D2. The handle 13 is detachably connected to the lock core 12, and the handle 13 protrudes outward from the lock body 11 along the second direction D2. Specifically, the handle 13 and the lock core 12 can be connected by a mutually matching threaded structure to facilitate the disassembly and assembly of the handle 13. Further, the lock body 11 also includes a limiting notch 11b suitable for the handle 13, and the handle 13 protrudes outward from the limiting notch 11b. In addition, the limiting notches 11b are arranged in pairs, and the extension directions of adjacent limiting notches 11b are consistent and spaced from each other. It should be noted that, Figure 4 and Figure 6 In the embodiment, the first direction D1 is configured as a vertical direction, and correspondingly, the second direction D2 is configured as a horizontal direction. In some embodiments not shown, the first direction D1 can be configured as a horizontal direction, and the second direction D2 can be configured as a horizontal direction or a vertical direction. In addition, the handle 13 can be configured as a round bar, and correspondingly, in order to clamp and limit the handle 13, the cross section of the limiting notch 11b is configured as an arc shape.

[0054] Return to Reference Figure 2 The loading member 22 also has a protrusion 22a, which is used to collide with the lock tongue 122. For example, in actual use, the lock body 11, the lock core 12 and the elastic member 15 are first assembled, and then the handle 13 is installed to limit the lock core 12 to prevent the lock core 12 from falling off relative to the lock body 11. Then the mounting member 14 is connected to the vehicle body 21 using the fastener 3. Please continue to refer to Figure 2 When locking the loading member 22, the loading member 22 is pulled to hit the contact surface 122a, so that the lock tongue 122 is retracted, and the protrusion 22a passes through the latch lock 1. The loading member 22 can be provided with a limiting groove suitable for the lock tongue 122. The lock tongue 122 is restored from the retracted position to the extended position under the action of the elastic member 15, so that the lock tongue 122 is inserted into the limiting groove. When unlocking is required, the handle 13 is pulled to rotate the lock core 12, thereby driving the lock tongue 122 to rotate 180°. At this time, the contact surface 122a faces the protrusion 22a, and the loading member 22 is pulled again to hit the contact surface 122a, so that the lock tongue 122 is retracted, and the protrusion 22a passes through the latch lock 1, thereby taking out the loading member 22 and completing the unlocking.

[0055] The latch lock 1 of the utility model has a reasonable and compact structure and is easy to operate. When locking and unlocking the trailer 2, the lock cylinder 12 only needs to be rotated so that the contact surface 122a faces the raised portion 22a of the loading member 22, and the raised portion 22a can be used to hit the lock tongue 12 to complete the unlocking and locking.
