Detailed Description

In order to make the technical problems solved, technical solutions adopted and technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, unless expressly stated or limited otherwise, the terms "connected," "connected," and "fixed" are to be construed broadly, e.g., as meaning permanently connected, removably connected, or integral to one another; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. 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 6, the luggage lock of the present invention includes a lock body 10, a zipper strip 20, and an upper unlocking mechanism 30 provided in the lock body 10. Wherein, the lock body 10 is provided with a slot 11 for inserting the zipper sheet 20; the upper unlocking mechanism 30 comprises a bolt 31 and a bolt control assembly 32, the bolt 31 is movably connected with the lock body 10, one end of the bolt 31 is close to the slot 11, and the bolt 31 is configured to be in inserted fit with the zipper strip 20 when the zipper strip 20 is inserted into the slot 11; the latch bolt control assembly 32 is configured to brake the latch bolt 31 and to be able to release the brake of the latch bolt 31. That is, when the latch 31 is in the active state, the fastener stringer 20 can be inserted into the slot 11 or withdrawn from the slot 11; when the latch 31 is in the braking state, the fastener element 20 is restricted in the slot 11 or inserted into the slot 11.

As the case lock, both the lock body 10 and the fastener piece 20 of the present invention can be connected to the slider 40. In order to make the zipper plate 20 capable of being in plug-in fit with the locking tongue 31, the zipper plate 20 is provided with an arc-shaped groove 21 in plug-in fit with the locking tongue 31. Because the path of the zipper plate 20 is arc-shaped in the process of inserting and pulling the zipper plate 20, the arrangement of the arc-shaped slot 21 is convenient for the zipper plate 20 to form a guiding relation with the bolt 31 when the zipper plate 20 is inserted into or withdrawn from the slot 11.

This case and bag lock utilizes spring bolt 31 and the cooperation of pegging graft of zip fastener piece 20, and the spring bolt 31 of setting up through last release mechanism 30 to the activity is braked, can realize locking, and the brake to spring bolt 31 is relieved to last release mechanism 30, can realize unblanking convenient operation.

Regarding the structure of the lock body 10, the lock body 10 of the present invention includes a first housing 12 and a second housing 13 detachably connected, the second housing 13 is connected with a bent stopper 14, and a slot 11 is formed between the stopper 14 and the second housing 13. The lock body 10 is configured to be detachable, so that the unlocking mechanism 30 can be conveniently installed. And the stop member 14 is used to form the slot 11 at the outside of the lock body 10, so as to facilitate the insertion of the zipper strip 20.

In order to enable the bolt 31 to be matched with the zipper piece 20 in an inserted manner, the bolt 31 is rotatably connected with the first shell 12, the second shell 13 is provided with a hole 15 which is opposite to the abutting piece 14, the end part of the bolt 31 close to the slot 11 can enter and exit the hole 15, and a first spring 33 is connected between the end part of the bolt 31 close to the slot 11 and the first shell 12. That is, when the latch tongue 31 is in the active state, in the process of inserting the slide fastener piece 20 into the slot 11, the slide fastener piece 20 presses the latch tongue 31 until the arc-shaped groove 21 faces the latch tongue 31, the end of the latch tongue 31 is inserted into the arc-shaped groove 21 under the action of the first spring 33, and at this time, the latch tongue 31 is braked by the latch tongue control assembly 32, so that the slide fastener piece 20 can be limited in the slot 11.

Specifically, the lock tongue control assembly 32 includes a movable block 321 and a wheel disc 322, the movable block 321 can move relative to the lock body 10, the wheel disc 322 is rotatably connected to the lock body 10, the wheel disc 322 is configured to drive the movable block 321 to move between a first position and a second position, when the movable block 321 is at the first position, the movable block 321 clamps the lock tongue 31, and the lock tongue 31 is in a braking state; when the movable block 321 is at the second position, the movable block 321 is separated from the latch bolt 31, and the latch bolt 31 is in an active state. That is, by controlling the position of the movable block 321, whether the movable block 31 is in a holding relationship with the tongue 31 or not is used to control whether the tongue 31 is braked or not.

In order to enable the movable block 321 to move between the first position and the second position, a second spring 323 is connected between one end of the movable block 321 and the lock body 10, and the other end of the movable block is abutted against the wheel disc 322; the wheel disc 322 is a cam structure, or the wheel disc 322 is provided with a clamping groove 3221 matched with the end part of the movable block 321. In this embodiment, a slot 3221 adapted to the end of the movable block 321 is provided in the wheel disc 322. When the rotary wheel disc 322 rotates to the end of the slot 3221 aligned with the movable block 321, the end of the movable block 321 is clamped into the slot 3221 under the action of the second spring 323, at this time, the movable block 321 does not contact the lock tongue 31, and the lock tongue 31 is in a movable state; the wheel disc 322 is continuously rotated to enable the clamping groove 3221 to pass over the movable block 321, the side wall of the wheel disc 322 presses against the movable block 321, the movable block 321 retreats and presses the second spring 323, and when the movable block 321 retreats to the limit position, the lock tongue 31 is tightly clamped, so that the lock tongue cannot move and bounce.

In order to accurately clamp the clamping groove 3221 with the movable block 321 when the wheel disc 322 is rotated, the wheel disc 322 of the present invention is a password wheel. Through the mode of setting up the password, grasp the joint position accurately, be convenient for lock and unblock.

It can be seen that the upper release mechanism 30 of the present invention is simple in construction and easy to operate, while also reducing overall manufacturing costs.

In conclusion, the suitcase lock can be used for conveniently opening and buckling 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.
