Description

Technical Field

[0001] This utility model relates to the field of alarm lock technology, specifically an alarm lock. Background Technology

[0002] The history of lock development is long. Early locks were mainly simple mechanical locks, such as ancient Chinese wooden locks and spring-loaded locks, as well as later European cam-operated and sliding spool locks. The pin tumbler lock, invented by American John Yale in 1848, became the most widely used lock in the world. With technological advancements, locks have gradually evolved towards electronic and smart locks. Alarm locks emerged in this context, combining the technologies of mechanical and electronic locks, marking a significant stage in lock development.

[0003] Traditional bicycle or electric bike locks typically use chain locks or U-locks. These locks are usually large and heavy, requiring separate carrying or hanging on the frame, which increases the burden of riding. Furthermore, relying solely on physical locking means that even if pried or cut, they cannot trigger an alarm to alert the user or deter thieves. Users often only realize they have been robbed after the fact, which is a significant drawback. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please refer to Figure 1 - Figure 7This utility model provides a technical solution: an alarm lock, including a lock body 1, the lock body 1 including a base 11 and a housing 12, a column 2 is fixedly installed on one side of the upper end of the housing 12, a sliding groove 22 is opened on one side of the middle of the column 2, a limiting groove 21 is opened on the other side of the middle of the column 2, a pressure block 30 is slidably engaged in the middle of the sliding groove 22, a pressure plate 33 is fixedly installed on one side of the pressure block 30, a limiting block 32 is fixedly installed on the other side of the pressure block 30, a fixing ring 23 is fixedly installed in the middle of the column 2, a spring 24 is sleeved on the outer side of the lower end of the fixing ring 23 and the pressure block 30, a plug rod 31 is rotatably installed in the middle of the pressure block 30, an octagonal hole 38 is opened in the middle of the upper end of the plug rod 31, an annular groove 34 is opened in the middle of the lower end of the plug rod 31, and a groove is opened on one side of the lower end of the middle of the plug rod 31. There is a notch 35. A fixed chamber 25 is fixedly installed at the bottom of the column 2. A locking block 26 is slidably engaged in the middle of the fixed chamber 25. Side plates 27 are fixedly installed on both sides of the middle of one end of the locking block 26. A spring 28 is fixedly installed at the other end of the locking block 26. Limiting plates 29 are fixedly installed at both ends of one side of the bottom of the column 2. Spring 24 is sleeved on the outside of the insertion rod 31. The pressure plate 33 is slidably engaged in the middle of the sliding groove 22. The limiting block 32 is slidably engaged in the middle of the limiting groove 21. One end of the locking block 26 abuts against the surface of the insertion rod 31. One end of the locking block 26 is engaged in the annular groove 34. The side plate 27 abuts against the locking block 26. One end of the spring 28 is fixedly connected to the inner wall of the fixed chamber 25. The notch 35 and the annular groove 34 are connected. The notch 35 and the rotating groove 37 are located on the same side.

[0018] In this embodiment, during use, the pressure block 30 can be pressed down by hand to drive the insertion rod 31 down along the middle of the fixing ring 23, so that it passes through the top of one end of the base 11 and is inserted into the middle of the bottom insertion hole 14. During the process, the pressure plate 33 will move down along the sliding groove 22, while the limiting block 32 will move down along the limiting groove 21, which can effectively ensure that the pressure block 30 is vertical. As the pressure block 30 is pressed down, the insertion rod 31 will also move down synchronously. At this time, the spring 24 is in a contracted state, and the locking block 26 is also abutting against the surface of the insertion rod 31. Since the annular groove 34 is concave, the annular groove 34 is concave. The diameter of the groove 34 is smaller than the diameter of the insertion rod 31. At this time, the second spring 28 is also in a compressed state. As the insertion rod 31 moves downward, when the annular groove 34 of the insertion rod 31 moves to the same height as the locking block 26, the second spring 28 will reset and drive the locking block 26 to engage in the middle of the annular groove 34, thereby limiting the insertion rod 31. At this time, the bottom of the insertion rod 31 will be exactly engaged in the middle of the bottom insertion hole 14, and the pressure plate 33 will also press on the top of the push switch 19, putting it in the open state. At this time, the entire device enters the locked state. When unlocking is required, the user can use the... The unlocking plate 40, which is matched with the column 2, is first aligned with the convex plate 41 on one side of the unlocking plate 40 and the centering groove 39 above the pressure block 30. Then, the entire plate is moved down so that the convex plate 41 enters the center of the centering groove 39. At this time, the octagonal screw 42 at the lower end of the unlocking plate 40 will be inserted into the octagonal hole 38 at the upper end of the insertion rod 31. Then, the unlocking plate 40 is rotated so that the convex plate 41 at its end moves along the rotating groove 37 until it touches the bottom. When the unlocking plate 40 rotates, it will drive the insertion rod 31 to rotate synchronously. When the notch 35 of the insertion rod 31 rotates to the locking block 26, the locking block 26 will no longer be stuck in the annular groove 34. Therefore, the limit on the insertion rod 31 will be canceled, and the spring 24 will reset synchronously, thereby driving the pressure block 30 and the insertion rod 31 to move upward. The lower end of the notch 35 is a slope. When the locking block 26 contacts the slope at the lower end of the notch 35, it will gradually move backward along it. At this time, the spring 28 will be gradually compressed until it returns to the ready-to-use state. When the pressure block 30 rebounds, the pressure plate 33 will cancel the triggering of the push switch 19, and the limit block 32 can prevent the pressure block 30 from coming out of the middle of the column 2. Then, the unlocking plate 40 can be flipped so that its protrusion 41 is aligned with the centering groove 39 to remove it.

[0019] Example 2: As Figure 1 - Figure 6As shown, an alarm mechanism 15 is fixedly installed on the other side of the upper middle part of the base 11. A push switch 19 is provided above one end of the alarm mechanism 15, and the push switch 19 abuts against the lower end of the pressure plate 33. A battery compartment 16 is provided on one side of the middle part of the alarm mechanism 15, and a buzzer 18 is provided below the middle part of the middle part of the alarm mechanism 15. A cover plate 17 is snapped onto the upper end of the battery compartment 16. A bayonet 13 is provided on one side of the middle part of the base 11, and a bottom insertion hole 14 is provided in the middle of one end of the bayonet 13. One end of the insertion rod 31 passes through the upper part of one end of the base 11 and is inserted into the middle of the bottom insertion hole 14. A housing 12 is threadedly connected to the upper end of the base 11. The alarm mechanism 15 and the column 2 are both located in the middle of the housing 12. One end of the pressure block 30 is slidably engaged with one end of the middle of the housing 12. A rotating groove 37 is provided in the middle of the upper end of the pressure block 30. A central groove 39 is provided on one side of the upper end of the pressure block 30. The central groove 39 and the rotating groove 37 are connected. The rotating groove 37 is at a 90-degree angle. An unlocking plate 40 is provided at the upper end of the pressure block 30. A protruding plate 41 is fixedly installed at one end of the unlocking plate 40. An octagonal screw 42 is fixedly installed at the lower end of the pressure block 30. The octagonal screw 42 is engaged in the middle of the octagonal hole 38. The protruding plate 41 is slidably engaged in the middle of the central groove 39. The protruding plate 41 is rotatably engaged in the middle of the rotating groove 37.

[0020] In this embodiment, when the pressure plate 33 triggers the push switch 19, if someone illegally touches the lock body 1, the buzzer 18 of the alarm mechanism 15 will emit a high-decibel alarm to promptly alert surrounding personnel and deter thieves. The battery compartment 16 can be fitted with button batteries or small dry batteries to provide continuous power to the alarm mechanism, ensuring the alarm function remains effective for a long time. The snap-fit ​​design of the cover plate 17 facilitates battery replacement and maintenance. The alarm mechanism and the column 2 are both integrated inside the housing 12, preventing dust and moisture intrusion and preventing human-caused damage to the alarm components, thus improving structural durability and anti-theft reliability. The convex plate 41 of the unlocking plate 40 slides and snaps into the central groove 39, and rotates and snaps into the rotating groove 37. The rotating groove 37 is designed at ninety degrees to ensure that only when the unlocking plate is rotated at the correct angle can the octagonal screw 42 rotate the insertion rod 31, avoiding accidental unlocking or false alarm triggering caused by accidental contact. The latch 13 of the base 11... It can be locked into the hole of the brake disc of the vehicle to be locked, and the bottom insertion hole 14 is aligned with the hole, so that when locking, the insertion rod 31 can pass through the hole of the brake disc and the bottom insertion hole 14, thereby fixing the entire device.

[0021] Working principle: like Figure 1 - Figure 7As shown, during use, first align the latch 13 and bottom insertion hole 14 of the base 11 with the external carrier, such as the brake disc hole. Then press the pressure block 30, causing the insertion rod 31 to move vertically downward along the fixing ring 23. During this process, the limiting block 32 slides along the limiting groove 21, and the pressure plate 33 slides along the sliding groove 22, ensuring that the vertical movement is without deviation. After the insertion rod 31 passes through the base 11, it is inserted into the bottom insertion hole 14, and at the same time, the first spring 24 is compressed and stored. During the downward movement, the locking block 26 is squeezed by the surface of the insertion rod 31, compressing the second spring 28 and maintaining a resisting state. When the annular groove 34 of the insertion rod 31 is flush with the locking block 26, the second spring 28 returns to its original position, which will push the locking block 26 into the annular groove 34, realizing the mechanical limitation of the insertion rod 31 and completing the locking. At this time, the bottom of the insertion rod 31 is located in the middle of the bottom insertion hole 14. In the locked state, the pressure plate 33 moves down and continuously presses the push switch 19 of the alarm mechanism 15, putting the alarm module in a ready-to-trigger state. At this time, the buzzer 18 does not sound an alarm, but is only in preparation for warning. Once someone illegally touches the lock body 1, such as prying or violently pressing the pressure block 30, the pressure of the pressure plate 33 on the push switch 19 changes abnormally, triggering the buzzer 18 of the alarm mechanism 15, causing it to emit a high-decibel alarm. The battery in the battery compartment 16 continuously powers the alarm module, and the cover 17 ensures stable battery installation and easy replacement. The housing 12 encloses and protects the alarm mechanism 15 and the column 2, preventing external interference or human damage and ensuring reliable alarm functionality.

[0022] During unlocking, the user aligns the protruding plate 41 of the matching unlocking plate 40 with the central groove 39 of the pressure block 30 and moves it downwards, allowing the octagonal screw 42 to insert into the octagonal hole 38 of the insertion rod 31. The protruding plate 41 then engages with the rotating groove 37, where the angle of the rotating groove 37 is a 90-degree limit to ensure a unique angle. The unlocking plate 40 is then rotated, causing the insertion rod 31 to rotate synchronously via the octagonal screw 42, rotating the notch 35 of the insertion rod 31 to the locking block 26. The inclined surface at the lower end of the notch 35 presses against the locking block 26, compressing the second spring 28 and disengaging it from the annular groove 34, thus releasing the restriction on the insertion rod 31. The first spring 24 then returns to its original position, pushing the pressure block 30 and the insertion rod 31 upwards. The insertion rod 31 is then pulled out of the bottom insertion hole 14, and the lock body 1 is released. When the pressure block 30 moves upwards, the pressure plate 33 disengages from the push switch 19, the alarm module stops its waiting-to-trigger state, and the limit block 32 prevents the pressure block 30 from dislodging from the column 2. Finally, rotate the unlocking plate 40 in the opposite direction so that the convex plate 41 is aligned with the centering groove 39, and then remove the unlocking plate 40. The device will then be restored to the locked state for easy use next time.
