TECHNICAL FIELD
[0001] The present utility model relates to the technical field of anti-theft locks, in particular to an alarmable handcuff lock. STATE OF THE ART
[0002] An anti-theft lock is a lock with an anti-theft function and comes in various types, including a handcuff lock. A handcuff lock is a handcuff-like anti-theft lock used to prevent the theft of mobility devices such as bicycles. Its structure consists of a lock cylinder, a limiting element, and a fixed handcuff ring and a movable handcuff ring. The movable handcuff ring is provided with a handcuff slot for interacting with the limiting element, and the lock cylinder serves to control the movement of the limiting element. When the limiting element interacts with the handcuff slot and the movement of the limiting element is limited by the lock cylinder, the handcuff lock is locked; otherwise, the movement of the limiting element is not limited by the lock cylinder.At this point, the movable handcuff ring can be moved.
[0003] At the same time, the existing handcuff lock itself can only be used for anti-theft protection by locking it, and there is no alarm device. Therefore, anti-theft protection can only be achieved through mechanical structures. However, if someone picks up the lock, the handcuff lock itself will not sound an alarm. Therefore, if the lock is successfully picked up, the means of transport will be stolen, so a handcuff lock with an alarm is necessary. CONTENT OF THE PRESENT UTILITY MODEL

[0018] Therefore, during actual use, when the lock cylinder 4 is rotated by the key, the protrusion 42 rotates with the rotation of the lock cylinder 4 until it contacts the button 6. At this time, the circuit board receives the information transmitted via the button 6 to drive the activation of the alarm. The orientation of the plane 42 of the lock cap 41 changes in turn to limit the movement of the limiting element 5. Since the alarm is activated, an alarm will be triggered when someone touches the handcuff lock, which can play a better role in anti-theft protection.
[0019] At the same time, it is driven by the rotation of the lock cylinder 4, that is, the locking and turning on the alarm are synchronized, and the unlocking and turning off the alarm are synchronized, so that it can be realized in one step, which is more convenient.

[0023] Therefore, during actual use, components such as circuit boards and alarms are isolated and protected by the arrangement of the cover plate 13. Furthermore, the cover plate 13 is removable, which facilitates later replacement of the internal structure and maintenance.
[0024] The detachable structure consists in that a snap fastener 131 is first arranged on the peripheral side of the cover plate 13, and the inner wall of the installation slot 12 is provided with a snap slot 121 corresponding to the snap fastener 131.
[0025] Therefore, during actual use, the cover plate 13 can be installed at the opening of the installation slot 12 through the cooperation of the snap lock 131 and the snap slot 121. The cover plate 13 is removed by applying a larger force.
[0026] For better tightness, seals are arranged at the openings of the cover plate 13 and the installation slot 12.
[0027] At the same time, it is provided that the alarm arrangement further comprises an installation element I 7 and an installation element II 8, wherein the alarm is arranged between the installation element I 7 and the cover plate 13, wherein a power supply is arranged between the installation slot 12 and the installation element II 8, wherein the installation slot 12 is further provided with a partition plate 122 between the installation element I 7 and the installation element II 8 in order to perform isolation and avoid mutual interference.
[0028] Furthermore, it is provided that the handle 1 is provided on one side of the alarm with a through hole III 14 for connection with at least two directions, wherein the handle 1 is provided with a through hole IV 15 and a through hole V 16 on the front and back of the through hole III 14, respectively, wherein the through hole IV 15 and the through hole V 16 are each connected to the through hole III 14, wherein the through hole IV 15 is connected to the inside of the handle 1 to be used for the sound outlet of the alarm, as in Fig. 1 to Fig. 3 shown.
[0029] Therefore, during actual use, multiple sounds can be realized through the arrangement of the through hole V 16 and the through hole III 14, which can expand the volume and propagation range of the alarm sound.
[0030] Furthermore, it is provided that an installation block 9 is arranged within the handle 1, wherein the installation block 9 is provided with a slotted rail 91, wherein one end of the limiting element 5 is arranged in the handcuff slot 31, wherein the other end of the limiting element 5 is located in the slotted rail 91 and an elastic element is arranged between the limiting element 5 and the slotted rail 91, as in Fig. 1 to Fig. 5 shown.
[0031] Therefore, the limiting element 5 moves in the slotted rail 91 during actual use and can be reset by the elastic element.
[0032] Furthermore, it is provided that a limiting block 92 is arranged on the inner wall of the slotted rail 91, wherein a contact surface 52 is arranged on the side of the limiting element 5 remote from the lock cylinder 4 such that, during actual use, the release of the limiting element 5 from the interior of the slotted rail 91 is limited by contact of the limiting block 92 with the contact surface 52.
[0033] The fixed handcuff ring 2 is formed in that the fixed handcuff ring 2 comprises a front plate 21 and a rear plate 22, wherein the front plate 21 and the rear plate 22 each comprise a handcuff ring 23 and a connecting plate 24, respectively, wherein the handcuff rings 23 of the front plate 21 and the rear plate 22 are each exposed by the handle 1, wherein a lock cylinder 4 and a limiting element 5 are arranged between the connecting plates 24 of the front plate 21 and the rear plate 22, wherein a connecting block 25 is arranged between the handcuff rings 23 of the front plate 21 and the rear plate 22, wherein a protective sleeve 26 is encased on the location where the fixed handcuff ring 2 is located outside the handle 1, as shown in Fig. 1 to Fig. 5 shown.
[0034] At the same time, it is provided that the handle 1 has a front shell 17 and a rear shell 18, wherein connecting plates 24 of the front plate 21 and the rear plate 22 are arranged between the front shell 17 and the rear shell 18, wherein a button 6 is arranged on the inner wall of the rear shell 18.
[0035] Therefore, the arrangement of the connecting plate 24 facilitates the installation of the fixed handcuff ring 2 during actual use. The arrangement of the front plate 21 and the rear plate 22, as well as the front shell 17 and the rear shell 18, thus achieves double protection and thus better protection of the internal structure.
[0036] Second, the connecting block 25 primarily serves a support and filling function. Second, a connecting structure consisting of connecting columns and holes is used between the connecting block 25 and the handcuff ring 23. The arrangement of the protective sleeve I 26 prevents scratches from the user while simultaneously protecting the handcuff ring 23.
[0037] The movable handcuff ring 3 is formed in that the movable handcuff ring 3 comprises an arcuate plate 32 and a protective sleeve II 33 which is sheathed on the outside of the arcuate plate 32, as shown in Fig. 1 to Fig. 5 shown.
[0038] The lock cylinder 4 is formed in that a connecting element 10 is encased on the outside of the lock cylinder 4, wherein the connecting element 10 is arranged between the front plate 21 and the rear plate 22 and is connected to the front plate 21 and the rear plate 22.
[0039] The connections between many components in the present utility model are mainly used as screw connections, for example, between the front shell 17 and the front plate 21 and between the rear shell 18 and the rear plate 22. Second, an axial connection is also used. For example, there may be two arcuate plates 32 of the movable handcuff ring 3, and the axial connection is used between the two. At the same time, a snap connection is also used, for example, the adaptation of convex ridges and slots between the front shell 17 and the rear shell 18.
