Description

Technical Field

[0001] This utility model relates to the field of luggage technology, specifically a novel luggage lock. Background Technology

[0002] Bag latches are used to fasten the top and bottom flaps of bags. They generally consist of a movable part and a fixed part, and the opening and closing of the bag is achieved by the engagement and disengagement of the movable and fixed parts. Due to their superior functionality, bag latches are widely used in bags, making it crucial to ensure that bag latches can quickly open and close bags.

[0003] However, existing locks are prone to deformation during long-term use, resulting in unstable fixing function. When the bag is dropped or impacted, the internal structure of the lock is deformed by the impact, which can cause the bag to release its locking state and open on its own, causing the contents to fall out. The locking is not stable enough. There is an urgent need for a new type of bag lock to solve the above problems. Summary of the Invention

[0004] The technical problem solved by this utility model is to overcome the defects of the prior art and provide a new type of bag lock.

[0026] A sleeve 11 is fixedly connected to the front side of the movable plate 9 near the bottom. A second vertical groove 12 and an arc-shaped groove 13 are provided on the front side of the second protective shell 4. The second vertical groove 12 and the arc-shaped groove 13 are interconnected. The sleeve 11 is matched with both the second vertical groove 12 and the arc-shaped groove 13. The front end of the sleeve 11 movably passes through the second vertical groove 12. A spring 14 is provided inside the sleeve 11 and is fixedly connected to the front side of the movable plate 9.

[0027] Working Principle: This utility model discloses a novel bag lock. Firstly, it is installed on the bag's lid and body via a first mounting plate 1 and a second mounting plate 2, respectively. When it is necessary to unlock the bag, pull the knob 19 forward. The knob 19, through the connecting rod 17, moves the limiting rod 15 forward, while the spring 14 stretches. The connecting rod 17 moves within the cavity of the through hole 18, and the limiting rod 15 moves within the cavity of the slot 16. The limiting rod 15 moves with the knob 19 away from the first limiting slot 20, thereby releasing the fixation of the sleeve 11 and the movable plate 9. Then, maintaining the forward pull of the knob 19, the knob 19 is moved upward. The knob 19 moves the sleeve 11 upward, causing the sleeve 11 to move within the cavity of the second vertical sliding groove 12. The sleeve 11 then moves the movable plate 9 within the second vertical sliding groove 12. The outer side of the second fixed shaft 6 moves, the movable plate 9 drives the snap fastener 7 to move upward. When the snap fastener 7 drives the snap groove 8 to move away from the first fixed shaft 5, the sleeve 11 moves to the top of the second vertical slide groove 12. Then, the sleeve 11 rotates the movable plate 9 and the snap fastener 7 clockwise. The movable plate 9 and the snap fastener 7 rotate around the second fixed shaft 6. The sleeve 11 moves in the inner cavity of the arc-shaped slide groove 13. When the movable plate 9 and the snap fastener 7 rotate to the horizontal state, the sleeve 11 drives the limiting rod 15 to rotate to correspond with the second limiting groove 21. Then, the pull force of the knob 19 to the forward side is released. The limiting rod 15 moves to the rear side under the elastic action of the spring 14. The limiting rod 15 moves to the inner cavity of the second limiting groove 21, thereby fixing the angle of the movable plate 9 and the snap fastener 7. At this time, the lock of the bag is also released.

[0028] When locking the bag is required, pull the knob 19 forward. The knob 19, through the connecting rod 17, moves the limiting rod 15 forward, while the spring 14 stretches. The connecting rod 17 moves within the cavity of the through hole 18, and the limiting rod 15 moves within the cavity of the slot 16. The limiting rod 15 moves with the knob 19 away from the second limiting slot 21, thereby releasing the fixation of the sleeve 11 and the movable plate 9. Then, maintaining the forward pull of the knob 19, the movable plate 9 and the locking piece 7 are rotated counterclockwise through the sleeve 11. The movable plate 9 and the locking piece 7 rotate around the second fixed axis 6, and the sleeve 11 moves within the cavity of the arc-shaped slide groove 13. When the movable plate 9 and the locking piece 7 rotate to a vertical position, the knob is then moved downward. Button 19, the knob 19 drives the sleeve 11 to move downward, the sleeve 11 moves in the inner cavity of the second vertical slide groove 12, the sleeve 11 drives the movable plate 9 to move outside the second fixed shaft 6, the movable plate 9 drives the snap fastener 7 to move downward, when the snap fastener 7 drives the snap groove 8 to move and wrap around the outside of the first fixed shaft 5, the sleeve 11 moves to the bottom of the second vertical slide groove 12, at this time the sleeve 11 drives the limiting rod 15 to move to correspond with the first limiting groove 20, then the knob 19 is released to pull forward, the limiting rod 15 moves backward under the elastic action of the spring 14, the limiting rod 15 moves to insert into the inner cavity of the first limiting groove 20, thereby fixing the angle of the movable plate 9 and the snap fastener 7, at this time the locking of the bag is also completed;

[0029] By setting the limiting rod 15 and the first limiting groove 20, the locking component 7 can be limited, and the movement trajectory of the sleeve 11 is limited by the arc-shaped sliding groove 13 and the second vertical sliding groove 12, which effectively prevents the locking component 7 from moving and rotating on its own, causing the bag to lose its locking state. This solves the problem that the original buckle is prone to deformation during long-term use, resulting in unstable fixing function. It also avoids the bag from being released due to deformation caused by impact, thereby preventing the bag from opening on its own and causing its internal items to fall out, thus improving the locking stability of this utility model.
