Description

Technical Field

[0001] This utility model relates to locks, and more particularly to a push-button double-hook luggage lock and a suitcase having the push-button double-hook luggage lock. Background Technology

[0002] With the development of society and the economy, people have more opportunities to go out. When going out, they will inevitably carry some items for work or personal needs. In order to ensure the proper preservation and management of the items they carry, they generally use bags to preserve and manage the items they carry. Bags need to use combination locks. Combination locks are widely used in travel bags because they do not require keys and are very convenient to use.

[0003] In existing technology, most combination locks for bags and luggage include a push-operated mechanism, and most individual push-operated mechanisms can only control the locking or unlocking of a single lock hook and latch. Furthermore, most combination locks with push-operated mechanisms integrate the push-operated mechanism with the lock cylinder, requiring both combination lock and key unlocking to be performed by pushing or rotating both the push-operated mechanism and the lock cylinder. This results in a complex lock cylinder design, and because the lock cylinder can move, it requires higher precision during installation. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a button-type double-hook luggage lock.

[0005] The purpose of this utility model is achieved through the following technical solution: a button-type double-hook luggage lock, including a lock shell, a combination wheel assembly, a lock cylinder assembly, a button, a limiting plate that can be lowered or raised to allow for adjustment, a left locking rod, and a right locking rod. The left locking rod is connected to the adjustment plate, and the other end of the adjustment plate is connected to the right locking rod through a rotating component. One end of the right locking rod is provided with a button adjustment hole, and the bottom of the button extends into the button adjustment hole. Both sides of the button adjustment hole are provided with blocks, and the bottom of the button is provided with a pressing notch. The side wall of the pressing notch is provided with a pressing slope, and the pressing slope contacts the blocks.

[0006] When locked, the limiting plate restricts the movement of the relief plate; the button cannot be pressed down.

[0007] In the unlocked state, the limiting plate releases its restriction on the movement of the yielding plate by sinking or tilting upwards. Pressing the button moves the right locking lever, which in turn moves the left locking lever via a rotating component and the yielding plate. The inclined surface on the button pushes the right locking lever, which in turn moves the yielding plate and the left locking lever via a rotating component. The left and right locking levers move in opposite directions.

[0008] As an improvement of the button-type double-hook luggage lock of this utility model, the middle part of the relief plate is provided with a through hole, and a top protrusion is provided on one side wall of the through hole. An upper relief notch is formed between the top protrusion and the upper edge of the through hole, and a lower relief notch is formed between the top protrusion and the lower edge of the through hole.

[0009] As an improvement of the button-type double-lock hook luggage lock of this utility model, the limiting plate is provided with a plurality of abutting and yielding rods at intervals, each of the abutting and yielding rods is provided with a V-shaped protrusion, one end of the limiting plate is provided with a spring, and one side of the limiting plate is provided with a limiting block, the limiting block extending into the through hole;

[0010] When the password is unlocked, the limiting block tilts upward to the position corresponding to the upper clearance notch; the limiting plate removes the restriction on the movement of the clearance plate, and the clearance plate can then move.

[0011] When the key is unlocked, the limiting block sinks to the position corresponding to the lower clearance notch, the limiting plate removes the restriction on the movement of the clearance plate, and the clearance plate can then move.

[0012] As an improvement of the button-type double-lock hook luggage lock of this utility model, the combination wheel assembly includes a combination wheel, the lock cylinder assembly includes a lock cylinder and a lock cylinder sleeve, the lock cylinder is installed in the lock cylinder sleeve, and a rotating block is provided at the bottom of the lock cylinder;

[0013] When unlocking with a password, the correct password is entered on the password wheel. One end of the limiting plate tilts upward and removes the restriction on the movement of the yielding plate. Pressing the button can simultaneously move the left locking rod and the right locking rod. The left locking rod and the right locking rod remove the restriction on the rotation of the lock hook, and the lock hook removes the restriction on the removal of the lock buckle.

[0014] When unlocking with the key, the lock cylinder is turned by the key, which drives the rotating block to rotate. As the rotating block rotates, it pushes one end of the limiting plate downward, thus removing the restriction on the movement of the yielding plate. Pressing the button simultaneously moves the left and right locking rods, which remove the restriction on the rotation of the lock hook. The lock hook also removes the restriction on the removal of the latch.

[0015] As an improvement of the button-type double-lock hook bag lock of this utility model, the lock buckle is provided as two, and the lock shell is provided with lock buckle through holes at the positions of the two lock buckles;
