[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figure 1-Figure 3As shown, this embodiment discloses a latch-type annular lock, including a first buckle body 1, a second buckle body 2 and a lock core 4. One end of the first buckle body 1 is rotatably connected to one end of the second buckle body 2, and the other end of the first buckle body 1 and the other end of the second buckle body 2 can be connected to form an annular buckle body. The lock core 4 is telescopically connected to the other end of the first buckle body 1, and the lock core 4 can be inserted into the other end of the second buckle body 2 to lock the annular buckle body. The first buckle body 1 and the second buckle body 2 rotate relative to each other to complete the opening and closing action. The lock core 4 telescopically moves along the diameter, so that after the lock core 4 is inserted into the first buckle body 1, the first buckle body 1 and the second buckle body 2 can be locked, and the lock is firmly locked. The lock is unlocked by pulling the lock core 4, and the unlocking action is simple and convenient. In addition, the annular lock body is beautiful in appearance when matched with luggage.

[0029] Furthermore, a slide groove 22 is provided in the other end of the second buckle body 2, and a through hole 23 coaxial with the slide groove 22 is provided at the bottom of the slide groove 22. The diameter of the through hole 23 is smaller than the diameter of the slide groove 22 to form a step, so that the lock core 4 cannot fall off from the first buckle body 1. A part of the lock core 4 slides in cooperation with the through hole 23, and another part of the lock core 4 slides in cooperation with the slide groove 22. The lock core 4 is in cooperation along its axial direction, and the movement of the lock core 4 is stable and not easy to deviate, and it can remain smooth after long-term use.

[0030] Preferably, the lock core 4 is configured to be polygonal, and the cross section of the through hole 23 is the same as the cross section of the lock core 4 , and the two cooperate to prevent the lock core 4 from rotating around its axis, which would cause the lock head 41 to be misaligned.

[0031] Furthermore, a lock head 41 is provided at one end of the lock core 4 facing the first buckle body 1, and a front end of the lock head 41 is provided with an inclined surface. The other end of the lock core 4 extends through the through hole 23 to the outside of the second buckle body 2. The diameter of the lock head 41 is larger than the diameter of the lock core 4 to form a step to prevent the lock core 4 from escaping from the slide groove 22. The inclined surface on the lock head 41 contacts the other end surface of the first buckle body 1 when locking, and is used to guide the first buckle body 1 and the second buckle body 2 to dock and lock. When locking, the first buckle body 1 has a sense of sudden lock when it falls into the lock, and the locking feel is good.

[0032] Preferably, a pull ring 7 is further included, which is rotatably connected to the outward end of the lock core 4. The pull ring 7 is used to be pulled when unlocking, and can also be used to connect a strap to facilitate manual pulling of the lock core 4.

[0033] Furthermore, a lock hole 12 is provided on the other end of the first buckle body 1, and the lock core 4 falls into the lock hole 12. The lock hole 12 is a through hole to prevent dust accumulation inside from affecting the locking. It is easy to clean and use. The lock hole 12 and the lock head 41 form a gap fit, so that the first buckle body 1 and the second buckle body 2 cannot be disengaged after being locked.

[0034] Preferably, it also includes a first elastic member 6, which is sleeved on the lock core 4, one end of the first elastic member 6 is in conflict with the end face of the lock head 41, and the other end of the first elastic member 6 is in conflict with the end face of the slide groove 22 close to the through hole 23. The first elastic member 6 is used to extend the lock core 4 for reset. The lock core 4 is automatically locked under the support of the first elastic member 6. When in use, you only need to merge the first buckle body 1 into the second buckle body 2. There is no need to operate the lock core 4. The locking action is simple, and the first elastic member 6 is a compression spring.

[0035] Preferably, it also includes a rotating shaft 3, a protrusion 13 is provided on one end of the first buckle body 1, and a recessed portion 24 is provided on one end of the second buckle body 2. The protrusion 13 is connected to the recessed portion 24 by rotating the rotating shaft 3, and the protrusion 13 falls into the recessed portion 24 and rotates through the rotating shaft 3, so that the overall appearance of the first buckle body 1 and the second buckle body 2 is beautiful after being locked.

[0036] More preferably, it also includes a second elastic member 5, a first groove 11 is provided on one end of the first buckle body 1, and a second groove 21 is provided on one end of the second buckle body 2. The middle part of the second elastic member 5 is sleeved on the rotating shaft 3, one end of the second elastic member 5 is in contact with the first groove 11, and the other end of the second elastic member 5 is in contact with the second groove 21. The second elastic member 5 provides elastic force for locking the first buckle body 1 and the second buckle body 2. The first buckle body 1 and the second buckle body 2 tend to merge in the open state to prevent deformation and damage when the lock is opened, and are easy to lock and use.

[0037] The second elastic member 5 is a torsion spring, which provides a rotational elastic force around an axis.

[0038] The working process of the latch-type ring lock is as follows:

[0039] When unlocking, hold the pull ring 7 and pull the lock core 4 backward, and the lock head 41 on the lock core 4 will come out of the lock hole 12 of the second buckle body 2, and then separate the first buckle body 1 and the second buckle body 2 to complete the unlocking of the lock; when locking, release the first buckle body 1 and the second buckle body 2, and the two will merge under the action of the second elastic member 5. Force the lock hole 12 of the first buckle body 1 to fall onto the inclined surface of the lock head 41, and press down along the axial direction of the lock core 4, so that the other end of the first buckle body 1 presses the lock head 41 downward and slides. After pressing down for a distance, the lock head 41 rebounds under the action of the first elastic member 6, and the lock head 41 falls into the lock hole 12, and the first buckle body 1 and the second buckle body 2 are locked.

[0040] Example 2

[0041] This embodiment also discloses a bag, including a latch-type annular lock buckle, which is installed on the opening or surface of the bag. The bag has a good overall aesthetics and can be locked and unlocked with one hand, making it easy to operate.

[0042] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and any modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience of description only and do not constitute any limitation to the present invention.
