[0026] A detachable luggage lock, comprising a lock body and a handle 1 located on one side of the lock body and detachable from the lock body, the lock body is fixedly connected to the luggage body, the handle 1 is fixedly connected to the front cover of the luggage, the front cover of the luggage is connected to the luggage body through a zipper, the lock body comprises a shell 2, a lock mechanism 3, a handle 1 fixing structure and a zipper head fixing structure 16 are arranged on the shell 2, the handle 1 fixing structure comprises an unlocking block 4 slidable on the surface of the shell 2, a driving block 5 slidably connected to the shell 2, a first locking block 6 located on one side of the driving block 5 and a first hook 7 rotatably connected to the shell 2, the unlocking block 4 can drive the driving block 5 to move, and a spring (located at the attached Figure 1 The handle 1 is provided with a snap ring 8 corresponding to the first hook 7, the driving block 5 is provided with a first hook groove 9, the first locking block 6 is provided with a second hook groove 10, the end of the first hook groove 9 is located in the second hook groove 10, the end of the second hook groove 10 is located in the first hook groove 9, and each has a certain activity space, a spring 1.1 is provided between the first locking block 6 and the housing 2, a torsion spring is provided on the rotating shaft of the first hook 7, a lock groove 11 is provided on the first locking block 6, a card groove 12 is provided on one side of the lock groove 11, and a first stopper 13 is provided on the first hook 7. After the first stopper 13 is located in the lock groove 11, it can prevent the first hook 7 from rotating under the action of the torsion spring.

[0027] Principle of separation of the lock body and the handle 1: When the lock mechanism 3 is unlocked, the unlocking block 4 can be pushed, and the unlocking block 4 drives the driving block 5 to move, and the driving block 5 drives the first locking block 6 to move, so that the first stopper 13 on the first hook 7 is moved out of the lock groove 11 on the first locking block 6. At this time, the first hook 7 rotates under the torsion force of the torsion spring, so that the first hook 7 is separated from the snap ring 8 on the handle 1. At this time, the handle 1 can be pulled to drive the front cover of the bag to open;

[0028] The movement of the first locking block 6 will cause the spring 1.1 between the first locking block 6 and the housing 2 to generate elastic force (reset elastic force), and when the first stopper 13 moves out of the lock slot 11, the first stopper 13 will be located in the card slot 12, so that the first locking block 6 is blocked by the first stopper 13 being located in the card slot 12, so that the first locking block 6 is kept in the unlocked state;

[0029] When locking, first connect the front cover of the bag with the zipper of the bag body, then push the handle 1, the snap ring 8 on the handle 1 drives the first hook 7 to rotate against the torsion force of the torsion spring until the first hook 7 hooks the snap ring 8, and at the same time, the first stopper 13 is disengaged from the slot 12, and the first locking block 6 moves under the resetting elastic force of the spring 1.1, so that the first stopper 13 re-enters the lock slot 11, and again passes through the lock slot 11 to prevent the first hook 7 from rotating, thereby locking the handle 1;

[0030] By providing a lockable handle 1 on the front cover of the bag, even if the zipper head is damaged and the zipper is opened, the front cover of the bag cannot be opened or fully opened because the handle 1 is still in a locked state, thereby improving the safety of the items in the bag.

[0031] like Figure 5 As shown, in the present embodiment, preferably, both sides of the driving block 5 are provided with a first hook groove 9 and a first locking block 6, two first hooks 7 are provided on the shell 2, and two snap rings 8 are provided on the handle 1 to improve the locking effect of the handle 1.

[0032] like Figure 3 As shown, in this embodiment, preferably, when unlocking, the first hook groove 9 on one side of the driving block 5 pushes the first locking block 6 to overcome the elastic force of the spring 1.1 and moves in the corresponding second hook groove 10 through the end, and the first hook groove 9 on the other side of the driving block 5 hooks the corresponding second hook groove 10 through the end to pull the first locking block 6 to overcome the elastic force of the spring 1.1 and move, so that when the first locking block 6 is blocked by the first stopper 13, the driving block 5 is in the spring between the unlocking block 4 and the housing 2 (located in the attachment Figure 1 The machine is reset by moving under the reset spring force at the position marked with X in the middle.

[0033] like Figure 3 As shown, in the present embodiment, preferably, the handle 1 is provided with a protrusion 14, and the shell 2 is slidably connected with a slider 15 corresponding to the protrusion 14, and a spring 1.2 is provided between the slider 15 and the shell 2. When the handle 1 is in an unlocked state, the end face of the slider 15 is flush with or protrudes from the surface of the shell 2. When the handle 1 is connected, the protrusion 14 contacts the end face of the slider 15, thereby pushing the slider 15 in and compressing the spring 1.2 at the same time, reducing the sense of frustration when the first hook 7 clamps the column clamping ring 8, and improving the feel when the handle 1 is pushed in.

[0034] like Figure 6 As shown, in this embodiment, preferably, the locking mechanism 3 is a mechanical combination lock, which includes a telescopic rod, on which a spring 1.3 is provided. When the telescopic rod is fixed, the unlocking block 4 cannot move the unlocking handle 1 and the zipper head. When the telescopic rod is retractable, the unlocking block 4 can move the unlocking handle 1 and the zipper head.

[0035] Preferably, the lock mechanism 3 may also be an electronic password lock or a fingerprint lock to control the fixation and extension of the telescopic rod.

[0036] like Figure 6 As shown, in this embodiment, the zipper head fixing structure 16 and the lock mechanism 3 are respectively located on both sides of the handle 1 fixing structure, and the zipper head fixing structure 16 includes a push plate 17, a second lock block 18 connected to the push plate 17 in a wedge-shaped sliding manner, and a second hook 19 rotatably connected to the housing 2, and a spring (located at the attachment) is arranged between the second lock block 18 and the housing 2. Figure 1 The rotating shaft of the second hook 19 is provided with a torsion spring (located at the Figure 1 The second locking block 18 is provided with an unlocking groove 20, and the second hook 19 is provided with a second stopper 21. After the second stopper 21 contacts the second locking block 18, the second hook 19 can be blocked from rotating under the action of the torsion spring. The push plate 17 abuts against the unlocking fast 4 through the spring between the unlocking fast 4 and the shell 2. A linkage structure is provided between the unlocking fast 4 and the lock mechanism 3. When the lock mechanism 3 is locked, the handle 1 and the zipper head cannot be unlocked through the linkage structure. When the lock mechanism 3 is unlocked, the handle 1 and the zipper head can be unlocked by moving the unlocking fast 4 to both sides respectively.

[0037] Unlocking principle of the zipper head: When the lock structure is unlocked, the unlocking block 4 can move toward the zipper head fixing structure 16, and at the same time drive the push plate 17 to move. The push plate 17 overcomes the spring elastic force (reset elastic force) and causes the second lock block 18 to move by overcoming the spring elastic force at the same time through the wedge surface structure. When the unlocking groove 20 corresponds to the second stopper 21 on the second hook 19, the second hook 19 rotates under the torsion force of the torsion spring, so that the second stopper 21 enters the unlocking groove 20, and the originally locked zipper head can be released.

[0038] When the second stopper 21 enters the unlocking groove 20, the second locking block 18 is fixed due to the obstruction of the second stopper 21, and the push plate 17 wedge-shaped slidingly connected to the second locking block 18 is also fixed. When the zipper head is inserted again, the zipper head presses down and rotates the second hook 19, so that the second stopper 21 rotates out of the unlocking groove 20. At this time, the spring connected to the second locking block 18 and the spring connected to the push plate 17 release the elastic force, so that the push plate 17 and the second locking block 18 are reset, and the push plate 17 is again in contact with the unlocking fastener 4.

[0039] Preferably, in this embodiment, a concave hole is provided on the push plate 17, and a wedge-shaped block extending into the concave hole is provided on the second locking block 18, and the wedge-shaped block and the side wall of the concave hole abut against each other through a wedge-shaped surface.

[0040] like Figure 2As shown, in this embodiment, preferably, the unlocking fastener 4 is provided with a driving rod 22, and the driving block 5 is provided with a driving hole 23 for the driving rod 22 to extend into. The unlocking fastener 4 moves to make the driving rod 22 move in the driving hole 23. When the driving rod 22 contacts the inner wall of the driving hole 23, the driving block 5 or the push plate 17 can be driven to move, so that when the unlocking fastener 4 moves to one side, it will not affect the unlocking of the mechanism on the other side, that is, the handle 1 and the zipper head can be unlocked separately through the unlocking fastener 4.

[0041] like Figure 7 As shown, in the present embodiment, preferably, the linkage structure includes a linkage baffle 26 rotatably connected to the shell 2, a first limit block 27 is provided on the shell 2, and the first limit block 27 is located on the upper end of the linkage baffle 26, close to the zipper head fixing structure 16, and a second limit block 28 is provided on the unlocking fastener 4, and the second limit block 28 is located on the lower end of the linkage baffle 26, away from the zipper head fixing structure 16, and the upper end of the linkage baffle 26 abuts against the lock mechanism 3.

[0042] When the lock mechanism 3 is in a locked state, since the upper end of the linkage baffle 26 abuts against the lock mechanism 3, and the second limit block 28 on the unlocking block 4 contacts the linkage baffle 26, the unlocking block 4 cannot move toward the zipper head fixing structure 16, so that the handle 1 and the zipper head cannot be unlocked when the lock structure is locked;

[0043] When the lock mechanism 3 is in unlocked state, the linkage baffle 26 is driven by the unlocking block 4 to rotate with its upper end abutting against the lock structure, so that the handle 1 and the zipper head can be unlocked separately by moving to both sides.

[0044] like Figure 1 As shown, in this embodiment, preferably, another driving hole 23 symmetrical to the driving hole 23 is provided on the driving block 5, and the two driving holes 23 simplify the assembly of the driving block 5, and when one of the driving holes 23 is matched with the driving rod 22, the other driving hole 23 can be used as a weight-reducing groove to reduce the weight of the driving block 5, and a weight-reducing hole 24 is also provided between the two driving holes 23 to further reduce the weight of the driving block 5.

[0045] like Figure 6 As shown, in this embodiment, preferably, two second locking blocks 18 are provided, which move simultaneously and in opposite directions after receiving the wedge-shaped thrust of the push plate 17, and can cooperate to lock the zipper with two zipper heads.

[0046] like Figure 1 As shown, in this embodiment, preferably, a USB interface 25 is provided on the housing 2 to facilitate connecting electronic products such as mobile phones on the surface of the bag.

[0047] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
