Description

Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to a chain lock with a double steel cable. Background Technology

[0002] Chain locks can be used to secure two-wheeled vehicles, especially bicycles. Due to the flexibility of the chain and the adaptability of the shape of the formed ring, chain locks can secure two-wheeled vehicles to fixed objects in various situations to prevent theft or unauthorized riding.

[0003] Most chain locks use a purely mechanical key mechanism for locking and unlocking, which is structurally insecure. Furthermore, few of these chain locks have electronic alarm functions, making them vulnerable to forced entry by criminals in unattended environments. They neither alert the user nor deter criminals, resulting in relatively poor anti-theft performance. With technological advancements, chain locks with electronic alarms have emerged, providing better security by emitting an audible alarm. However, these electronic alarms are typically controlled by a remote control, requiring frequent battery replacements and leading to higher maintenance costs and a poorer user experience. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a double-locking chain lock with steel cable, which, by setting a lock cylinder, a dial, a lock gate, an alarm button and a push sleeve to cooperate with each other to control the alarm switch by pressing the alarm inclined block, thereby controlling the opening or closing of the electronic alarm. It can activate the electronic alarm function according to the user's needs, and the user experience is good.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A double-locking chain lock with a steel cable includes a lock body with a steel cable attached. An electronic alarm and an inner frame are housed within the lock body. The electronic alarm has an alarm switch. The inner frame includes a lock cylinder, a dial, a lock gate, an alarm button, a push sleeve, and an alarm ramp. The dial engages with one end of the lock cylinder and the lock gate, respectively. A first return spring is mounted on the dial. The push sleeve is fitted over the outside of the alarm button, and the inside of the alarm button engages with the other end of the lock gate. A second return spring is mounted on the alarm button. The alarm ramp abuts against the push sleeve and the alarm switch, respectively.

[0007] Preferably, the first reset spring abuts against the dial and the inner frame respectively, the second reset spring abuts against the alarm button and the inner frame respectively, and a lock gate spring is provided on the lock gate, the lock gate spring abuts against the lock gate and the inner frame respectively.

[0008] Preferably, the electronic alarm includes a battery and an alarm circuit board electrically connected to the battery, and the alarm switch is mounted on the alarm circuit board.

[0009] Preferably, one end of the locking gate is provided with a first snap-fit ​​groove, and the outer side of the dial is provided with a first snap-fit ​​buckle that matches the first snap-fit ​​groove.

[0010] Preferably, a second snap-fit ​​groove is provided at the other end of the lock gate, and a second snap-fit ​​buckle that matches the second snap-fit ​​groove is provided on the inner side of the alarm button.

[0011] Preferably, the outer side of the alarm ramp is provided with a first ramp, and the outer side of the push sleeve is provided with a second ramp that matches the first ramp.

[0012] The present invention provides a double-locking chain lock with steel cable, which has the following advantages: The lock body of the double-locking chain lock with steel cable contains an electronic alarm and an inner frame. The electronic alarm has an alarm switch. The inner frame contains a lock cylinder, a dial, a lock gate, an alarm button, a push sleeve, and an alarm ramp. The dial is engaged with one end of the lock cylinder and the lock gate, and a first return spring is provided on the dial. The push sleeve is fitted onto the outside of the alarm button, and the inside of the alarm button is engaged with the other end of the lock gate. A second return spring is provided on the alarm button. The alarm ramp abuts against the push sleeve and the alarm switch. When the electronic alarm needs to be activated, pressing the alarm button activates the alarm. The key drives the push sleeve to move, which presses against the alarm ramp to activate the alarm switch. Simultaneously, the inner side of the alarm button engages with the lock gate. When the electronic alarm needs to be deactivated, the key rotates the lock cylinder, which in turn rotates the dial indicator, disengaging the lock gate from the alarm button. The alarm button then rebounds and resets under the action of the second reset spring, further resetting the push sleeve and disengaging the alarm ramp from the alarm switch. By coordinating the lock cylinder, dial indicator, lock gate, alarm button, and push sleeve to control the alarm ramp pressing the alarm switch, the electronic alarm can be activated or deactivated according to user needs. This eliminates the need for a remote control, resulting in lower maintenance costs and a better user experience. Attached Figure Description

[0021] like Figure 1-4As shown, the double-lock chain lock with steel cable includes a lock body 1, a steel cable 2 mounted on the lock body 1, an electronic alarm 3 and an inner frame 4 inside the lock body, an alarm switch 5 mounted on the electronic alarm 3, and a lock cylinder 6, a dial 7, a lock gate 8, an alarm button 9, a push sleeve 10, and an alarm ramp 11 mounted on the inner frame 4. The dial 7 engages with one end of the lock cylinder 6 and the lock gate 8, and has a first return spring 12 mounted on it. The push sleeve 10 is fitted onto the outside of the alarm button 9, and the inside of the alarm button 9 engages with the other end of the lock gate 8. The alarm button 9 has a second return spring 13 mounted on it. The alarm ramp 11 abuts against the push sleeve 10 and the alarm switch 5. It is understood that the electronic alarm 3 can be a general magnetic induction alarm, etc., which will trigger an alarm and emit an alarm sound when the lock body 1 is lightly tapped or shaken.

[0022] Specifically, the first reset spring 12 abuts against the dial 7 and the inner frame 4 respectively, for resetting the dial 7; the second reset spring 13 abuts against the alarm button 9 and the inner frame 4 respectively, for resetting the alarm button 9; a lock gate spring 14 is provided on the lock gate 8, which abuts against the lock gate 8 and the inner frame 4 respectively, for resetting the lock gate 8; the electronic alarm 3 contains a battery 15 and an alarm circuit board 16 electrically connected to the battery 15; the alarm switch 5 is installed on...
