The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

As shown in fig. 1 to 2, the luggage lock of the present invention includes a lock body 10, a zipper strip 20, a lock cover 30, and a lock cover control assembly. Wherein, the end of the lock body 10 has a slot 11 for inserting the zipper strip 20; the lock cover 30 is rotatably connected with the lock body 10, the lock cover 30 can rotate between a first position and a second position in a reciprocating manner, when the lock cover 30 is located at the first position, the zipper strip 20 can be inserted into and separated from the slot 11, and when the lock cover 30 is located at the second position, the zipper strip 20 is limited in the slot 11; the locking cover control assembly is connected to the lock body 10, and the locking cover control assembly can lock and unlock the locking cover 30 when the locking cover 30 is located at the first position and the second position. The zipper plate 20 is locked on the lock body 10 in an inserting mode, so that the operation is convenient; in addition, the zipper piece 20 can be limited to the lock body 10 or the limitation to the zipper piece 20 can be released by rotating the lock cover 30, so that the zipper piece 20 can be conveniently inserted into the lock body 10 and locked with the lock body 10; the rotation control of the lock cover 30 is realized by the lock cover control component, so that the locking and unlocking operations of the luggage lock are realized.

Specifically, as shown in fig. 2 and 4, the locking cover control assembly includes a button 41 and an elastic member, the button 41 is inserted into the lock body 10, and the button 41 has a locking tongue 42, the locking tongue 42 is configured to be locked and unlocked with the locking cover 30; one end of the elastic member is connected to the inside of the lock body 10 and the other end is connected to a portion of the button 41 extending into the lock body 10. Preferably, the button 41 is inserted through the side wall of the lock body 10, and the latch tongue 42 extends out of the top of the lock body 10; the locking cap 30 is located on top of the lock body 10. That is, the latch 42 is locked and unlocked with the lock cover 30 by the elastic member by pressing the button 41.

In order to facilitate the locking and unlocking of the locking tongue 42 on the locking cover 30, the corresponding locking cover structure is shown in fig. 5, the locking cover 30 is provided with a rotating shaft 31 rotatably connected with the lock body 10 and a guide groove 32 coaxial with the rotating shaft 31, and the guide groove 32 is in sliding fit with the locking tongue 42 and is provided with two notches 33 at intervals; when the lock cover 30 is located at the second position, the locking tongue 42 can enter and exit a corresponding one of the notches 33; when the locking cap 30 is in the first position, the locking tongue 42 can enter and exit the other notch 33. When the locking cover 30 is located at the first position, the locking cover 30 is deviated from the slot 11 of the lock body 10, and the locking tongue 42 is clamped in the corresponding notch 33; when the zipper piece 20 is inserted into the slot 11 from the top of the slot 11, the button 41 is pressed, the latch 42 is separated from the notch 33, the locking cover 30 is rotated, the latch 42 is tightly attached to the side wall of the guide groove 32, the guide groove 32 is in sliding contact with the latch 42 in the rotation process of the locking cover 30 until the locking cover 30 rotates to the second position, at the moment, the latch 42 is aligned with the other notch 33, and the latch 42 is automatically clamped into the notch 33 under the action of the elastic element; in the second position, the locking cover 30 completely covers the top of the slot 11, the zipper strip 20 cannot be separated from the top of the slot 11, and the locking cover 30 cannot rotate due to the locking tongue 42 being blocked in the corresponding notch 33, so as to lock the zipper strip 20 with the lock body 10. When unlocking, the button 41 is pressed to disengage the button 41 from the notch 33, and the locking cover 30 is rotated.

In order to easily rotate the locking cap 30, the side wall of at least one of the notches 33 in the present invention is provided with a guide slope 34 extending to the wall of the guide groove 32. The inclined surface 34 of the wire can make the lock tongue 42 slide out of the notch 33, and only slight force is needed when the lock cover 30 is rotated.

As for the structure of the lock body 10, as shown in fig. 3, the lock body 10 is provided with a shaft hole 12 corresponding to the position of the rotating shaft 31, and the shaft hole 12 is connected with a connecting pin which is sleeved with the rotating shaft 31. In this way, the lock cover 30 can stably rotate relative to the lock body 10 and will not be separated from the lock body 10 under the action of the connecting pin.

In order to precisely rotate the lock cover 30 to the first position and the second position, the lock body 10 of the present invention is further provided with a limiting groove 13 coaxial with the shaft hole 12, and the lock cover 30 is provided with a limiting post 35 slidably engaged with the limiting groove 13. The rotation angle of the lock cover 30 is limited by the limiting groove 13, and two ends of the limiting groove 13 respectively correspond to the first position and the second position.

Preferably, the radian range of the limiting groove 13 in the invention is pi/3-2 pi/3. The arc range is set to completely expose or completely cover the slot 11 when the locking cover 30 is rotated to the first position or the second position.

In the structure of the fastener element 20, as shown in fig. 6, the free end of the fastener element 20 of the present invention is provided with the columnar engaging head 21, and correspondingly, as shown in fig. 3, the insertion groove 11 has a narrow part 111 and an open part 112 communicating with each other, the width of the narrow part 111 is smaller than the diameter of the columnar engaging head 21, and the inner diameter of the open part 112 is equal to or larger than the diameter of the columnar engaging head 21. In this way, the fastener element 20 can be inserted into or removed from only the tip of the slot 11, and cannot enter or exit from the side of the slot 11.

In order to match two zippers of a case, the lock body 10 of the case lock is provided with two slots 1 so as to lock two zipper pieces 20.

In conclusion, the luggage lock is very convenient to open and buckle the zipper head, and has a good locking effect on the zipper.

The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
