[0002] At present, most luggage using snap locks generally only set a password lock on the snap lock to lock the buckle, and the handle on the front cover of the luggage only serves to conveniently open the front cover. Due to structural limitations, the snap lock is easily damaged by prying, resulting in relatively low overall security of the luggage. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a double-lock hook password lock for the front cover of a luggage, which improves the security of the luggage.

[0004] To achieve the above object, the utility model provides the following technical solution: A double-lock hook password lock for a luggage, comprising a lock body and a handle located on one side of the lock body and separable from the lock body. The lock body is fixedly connected to the luggage body, and the handle is fixedly connected to the front cover of the luggage. The lock body includes a housing, on which a lock mechanism and a handle fixing structure are provided. The handle fixing structure includes an unlocking block slidably connected to the housing, a driving block slidably connected to the housing, lock blocks located on both sides of the driving block and slidably connected to the housing, and a hook rotatably connected to the housing. The unlocking block can drive the driving block to move. A catch ring corresponding to the hook is provided on the handle. First hook grooves are provided on both sides of the driving block, and second hook grooves are provided on the lock blocks. The first hook grooves and the second hook grooves are movably hooked to each other. The driving block can drive the two lock blocks to move synchronously and in the same direction. A first spring is provided between the lock block and the housing. A torsion spring is provided on the rotating shaft of the hook. A lock groove is provided on the lock block, a card slot is provided on one side of the lock groove, and a stop block is provided on the hook. After the stop block is located in the lock groove, it can block the rotation of the hook under the action of the torsion spring.

[0005] Further, when unlocking, the end of the first hook groove on one side of the driving block pushes the lock block in the corresponding second hook groove to move against the elastic force of the first spring, and the first hook groove on the other side of the driving block pulls the lock block in the corresponding second hook groove to move against the elastic force of the first spring by hooking the end.

[0006] Further, a convex block is provided on the handle, a slider corresponding to the convex block is slidably connected to the housing, and a second spring is provided between the slider and the housing. The convex block is in contact with the slider under the elastic force of the second spring.

[0007] Further, a driving rod is provided on the unlocking block, and a driving hole for the driving rod to extend into is provided on the driving block.

[0021] A double-lock hook combination lock for a luggage case, comprising a lock body and a handle 1 located on one side of the lock body and separable from the lock body. The lock body is fixedly connected to the luggage case body, and the handle 1 is fixedly connected to the front cover of the luggage case. The lock body includes a housing 2, on which a lock mechanism 3 and a handle 1 fixing structure are provided. The handle 1 fixing structure includes an unlocking block 4 slidably connected to the housing 2, a driving block 5 slidably connected to the housing 2, lock blocks 6 located on both sides of the driving block 5 and slidably connected to the housing 2, and a hook 7 rotatably connected to the housing 2. The unlocking block 4 can drive the driving block 5 to move. A catch ring 8 corresponding to the hook 7 is provided on the handle 1. First hook grooves 9 are provided on both sides of the driving block 5, and second hook grooves 10 are provided on the lock blocks 6. The first hook grooves 9 and the second hook grooves 10 are movably hooked to each other, and the driving block 5 can drive the two lock blocks 6 to move synchronously and in the same direction. A first spring 11 is provided between the lock blocks 6 and the housing 2. A torsion spring 12 is provided on the rotating shaft of the hook 7. A lock groove 13 is provided on the lock block 6, and a card slot 14 is provided on one side of the lock groove 13. A stop block 15 is provided on the hook 7. After the stop block 15 is located in the lock groove 13, it can block the rotation of the hook 7 under the action of the torsion spring 12.

[0022] Such as Figures 1 to 5As shown in the figure, the separation principle of the lock body and the handle 1: When the lock mechanism 3 is unlocked, the unlocking block 4 can be pushed. The unlocking block 4 drives the driving block 5 to move, and the driving block 5 then drives the lock blocks 6 on both sides to move. When the stopper 15 on the hook 7 moves out of the locking groove 13 of the lock block 6, the hook 7 rotates under the torsional force of the torsion spring 12, causing the hook 7 to separate from the snap ring 8 on the handle 1. At this time, pulling the handle 1 can drive the front cover of the luggage to open;

[0023] The movement of the lock block 6 will compress the first spring 11 between the lock block 6 and the housing 2 to generate elastic force. After the stopper 15 moves out of the locking groove 13, the rotation of the hook 7 causes the stopper 15 to enter the card slot 14. At this time, the lock block 6 is blocked by the stopper 15 located in the card slot 14 to keep it in the unlocked state;

[0024] When locking the handle 1, push the handle 1. The snap ring 8 on the handle 1 contacts the hook 7 and drives the hook 7 to rotate against the torsional force of the torsion spring 12 until the hook 7 hooks the snap ring 8. At the same time, the stopper 15 turns from the card slot 14 to the locking groove 13, and the lock block 6 will move under the elastic force of the first spring 11, and the stopper 15 will re-enter the locking groove 13 to prevent the hook 7 from rotating through the locking groove 13, thus locking the handle 1.

[0025] A lock body is provided on the luggage body to lock the handle 1 on the front cover of the luggage through the lock body, and it is not easily damaged, further improving the safety of the luggage.

[0026] As Figures 1 to 1 As shown in the figure, the lock mechanism 3 is a mechanical password lock 16, which includes a telescopic rod 17. A return spring 18 is provided on the telescopic rod 17, and the end of the telescopic rod 17 is always in contact with the unlocking block 4. When the telescopic rod 17 is fixed, the unlocking block 4 cannot move. In the unlocked state, the telescopic rod 17 can be telescoped, and at this time, the unlocking block 4 can push the telescopic rod 17 to move and unlock the handle 1.

[0027] Preferably, the lock mechanism 3 can also be an electronic password lock or a fingerprint lock, etc. to control the fixing and telescoping of the telescopic rod 17

[0028] As Figure 1 As shown in the figure, in this embodiment, preferably, when unlocking, the end of the first hook groove 9 on one side of the driving block 5 pushes the lock block 6 in the corresponding second hook groove 10 to move against the elastic force of the first spring 11, and the first hook groove 9 on the other side of the driving block 5 pulls the lock block 6 in the corresponding second hook groove 10 to move against the elastic force of the first spring 11 by hooking the end.

[0029] As Figure 2As shown, in this embodiment, preferably, a convex block 19 is provided on the handle 1, a slider 20 corresponding to the convex block 19 is slidably connected to the housing 2, and a second spring 21 is provided between the slider 20 and the housing 2. The convex block 19 is in contact with the slider 20 by the elastic force of the second spring 21. When the handle 1 is in the unlocked state, the end face of the slider 20 is flush with or protrudes from the surface of the housing 2. When the handle 1 needs to be locked, the convex block 19 contacts the end face of the slider 20, thereby pushing the slider 20 in and compressing the second spring 21 at the same time, reducing the sense of jerk when the first hook 7 catches the clamping ring 8, improving the feel when the handle 1 is pushed in. At the same time, when the clamping ring 8 of the handle 1 is connected to the hook 7, the slider 20 will apply a force to the convex block 19 under the second spring 21, thereby preventing the handle 1 from shaking after being locked.

[0030] As Figure 2 and Figure 4 shown, in this embodiment, preferably, a driving rod 22 is provided on the unlocking block 4, and a driving hole 23 for the driving rod 22 to extend into is provided on the driving block 5.

[0031] As Figure 2 shown, in this embodiment, preferably, a weight-reducing hole 24 is provided on the driving block 5 to reduce the weight of the driving block 5.

[0032] As Figure 1 shown, in this embodiment, preferably, a USB interface 25 is provided on the outer shell, which is convenient for connecting electronic products such as mobile phones to the surface of the luggage.

[0033] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
