Description

Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to a double-locking motorcycle lock that is anti-sawing and anti-drilling. Background Technology

[0002] Locks are a perfect combination of human security needs and technological progress. The purpose of using locks is to protect one's belongings and personal space, prevent the theft or misappropriation of personal or public property, restrict others from freely entering private areas, and, in office and public settings, clearly define who can access specific resources to maintain order and security.

[0003] Insert the matching key. The key shape must correspond perfectly to the internal structure of the lock cylinder. The key teeth push the upper and lower pins in the lock cylinder to the same shear line, freeing the lock cylinder from the lock body's constraints and allowing it to rotate freely. Turning the key causes the bolt connected to the lock cylinder to retract, disengaging from the door frame latch and thus unlocking the lock.

[0004] However, because the internal core of the lock is simple and the key tooth shape combination is few, it is easy to be accurately matched. Furthermore, the key production threshold is low, and ordinary key duplication stalls can easily copy it. It can even be imitated with simple molds without the original key. Common tools such as pliers, crowbars, and screwdrivers can be used to directly pry open the lock body or smash the lock cylinder. The simple structure of the lock shell is thin and has poor strength, so it can be pried open directly. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a double-locking motorcycle lock that is anti-sawing and anti-drilling, aiming to improve the problem that the lock is easy to pry open due to its simple structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A saw-proof and drill-proof dual-locking motorcycle lock includes a housing, a lock body installed on the outer wall of the housing, key slots at both ends of the housing, a key inside the key slot, an idler housing installed inside the housing, a protective shell at one end of the idler housing, a rotor fixedly connected to the outer wall of the protective shell, a clutch mechanism installed at both ends of the protective shell, and an unlocking component inside the housing.

[0007] The above technical solution employs a double-latch structure to increase the difficulty of unlocking. Both ends of the outer shell are fixed with key slots, making it more difficult to pry open than a single key slot. Furthermore, the lock cylinder is equipped with a clutch mechanism. When there is no key or the wrong key is inserted, the clutch mechanism is not activated, allowing the free-spinning outer shell to rotate freely. Tools such as drill bits and screwdrivers can only drive the free-spinning outer shell to rotate, but cannot transmit torque to the internal rotor, thus achieving drill-proof protection. The entire lock body is made of high-strength alloy steel, which has high hardness and is resistant to shearing and sawing. The combination of the double lock cylinder and the free-spinning mechanism achieves the anti-theft effect.

[0008] Preferably, the unlocking component includes a lower pin, which is installed inside the housing. One end of the lower pin is provided with an upper pin, and the other end of the lower pin is provided with a return spring. A dust cover is installed on the outer wall of the housing.

[0009] Preferably, the key is disposed inside the housing, the protective shell is installed inside the housing, and the rotor is disposed inside the housing.

[0010] Preferably, the key is located inside the idling jacket, and the rotor is fixedly connected to the outer wall of the clutch mechanism.

[0011] Preferably, the housing has two sets of lock cylinders inside, which are located at opposite ends of the housing.

[0012] Preferably, the lower ball is located on one side of the idling jacket, and the upper ball is located on the other side of the idling jacket.

[0013] Preferably, the upper ball is installed inside the housing, and the return spring is installed inside the housing.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the device adopts a double-latch structure, with key slots fixed at both ends of the outer shell, making it more difficult to pry open than a single key slot. Furthermore, the lock cylinder is equipped with a clutch mechanism. When there is no key or the wrong key is inserted, the clutch mechanism is not activated, and the free-spinning outer shell can rotate freely. Tools such as drill bits and screwdrivers can only drive the free-spinning outer shell to rotate, and cannot transmit torque to the internal rotor to achieve drill-proof. The lock body is made of high-strength alloy steel, which has high hardness and is resistant to shearing and sawing.

[0015] 2. In this utility model, a dust cover is used to protect the inside of the lock cylinder, and the upper and lower pins are separated by the teeth on the key to unlock the lock. A return spring pushes the pins to return to their original position, ensuring that the lock cylinder remains in an idle state when it is not unlocked. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figures 1-4 One embodiment provided by this utility model: A saw-proof and drill-proof double-locking motorcycle lock includes a housing 1, a lock body 2 installed on the outer wall of the housing 1, key slots 3 at both ends of the housing 1, a key 4 inside the key slots 3, an idler housing 5 installed inside the housing 1, a protective shell 6 at one end of the idler housing 5, a rotor 7 fixedly connected to the outer wall of the protective shell 6, a clutch mechanism 8 installed at both ends of the protective shell 6, and an unlocking component inside the housing 1.

[0020] Specifically, this device adopts a double-latch structure, with key slots 3 fixed at both ends of the outer shell 1, making it more difficult to pry open than a single key slot 3. Furthermore, the lock cylinder is equipped with a clutch mechanism 8. When there is no key 4 or the wrong key 4 is inserted, the clutch mechanism 8 is not activated, and the free-spinning outer shell 5 can rotate freely. Tools such as drill bits and screwdrivers can only drive the free-spinning outer shell 5 to rotate, and cannot transmit torque to the internal rotor 7, thereby achieving drill-proof protection.

[0021] Reference Figure 3 The unlocking component includes a lower pin 9, which is installed inside the housing 1. One end of the lower pin 9 is provided with an upper pin 10, and the other end of the lower pin 9 is provided with a return spring 11. A dust cover 12 is installed on the outer wall of the housing 1.

[0022] Specifically, unlocking requires using the key 4 through the key slots 3 on both sides of the outer casing 1 to engage the internal clutch mechanism 8. Then, the key 4 is rotated again to unlock the lock body 2. The protective casing 6 prevents the drill bit from damaging the clutch mechanism 8, and the dust cover 12 protects the inside of the lock cylinder. The teeth on the key 4 push the upper pin 10 and the lower pin 9 apart to unlock the lock. The return spring 11 pushes the pins back to their original position, ensuring that the lock cylinder remains in an idle state when not unlocked, thus preventing theft.

[0023] Reference Figure 2The key 4 is located inside the outer casing 1, the protective casing 6 is installed inside the outer casing 1, and the rotor 7 is located inside the outer casing 1.

[0024] Specifically, to unlock, the key 4 is used through the key slots 3 on both sides of the outer casing 1 to engage the internal clutch mechanism 8. Then, the key 4 is rotated again to unlock the lock body 2. The protective casing 6 prevents the drill bit from damaging the clutch mechanism 8.

[0025] Reference Figure 3 The key 4 is located inside the idling jacket 5, and the rotor 7 is fixedly connected to the outer wall of the clutch mechanism 8.

[0026] Specifically, when there is no key 4 or the wrong key 4 is inserted, the clutch mechanism 8 is not activated, the idle outer sleeve 5 can rotate freely, and tools such as drill bits and screwdrivers can only drive the idle outer sleeve 5 to rotate, and cannot transmit torque to the internal rotor 7 to achieve drill prevention.

[0027] Reference Figure 1 The outer casing 1 has two sets of lock cylinders inside, which are located at both ends of the outer casing 1.

[0028] Specifically, this device adopts a double-latch structure, with key slots 3 fixed at both ends of the outer shell 1, which is more difficult to pry open than a single key slot 3. When unlocking, the key 4 is used through the key slots 3 on both sides of the outer shell 1 to unlock the internal clutch mechanism 8, and then the key 4 is rotated again to unlock the lock body 2.

[0029] Reference Figure 4 The lower ball 9 is located on one side of the idling jacket 5, and the upper ball 10 is located on the other side of the idling jacket 5.

[0030] Reference Figure 3 The upper ball 10 is installed inside the outer casing 1, and the return spring 11 is installed inside the outer casing 1.

[0031] Specifically, the upper pin 10 and lower pin 9 are popped apart by the teeth on the key 4 to unlock the lock. The pins are then pushed back to their original positions by the return spring 11, ensuring that the lock cylinder remains in an open-loop state when not unlocked, thus achieving the anti-theft effect.

[0032] Working Principle: This device adopts a double-latch structure. Both ends of the outer shell 1 are equipped with key slots 3 for fixation, which is more difficult to pry open than a single key slot 3. The lock cylinder is equipped with a clutch mechanism 8. When there is no key 4 or the wrong key 4 is inserted, the clutch mechanism 8 is not activated, and the free-spinning outer sleeve 5 can rotate freely. At this time, tools such as drill bits and screwdrivers can only drive the free-spinning outer sleeve 5 to rotate, and cannot transmit torque to the internal rotor 7 to achieve the anti-drilling function. The lock body 2 is made of high-strength alloy steel with extremely high hardness and excellent anti-shear and anti-sawing performance. To unlock, the key 4 must be inserted through the key slots 3 on both sides of the outer shell 1 to activate the internal clutch mechanism 8. Then, the key 4 is rotated again to unlock the lock body 2. In addition, the device is equipped with a protective shell 6 to prevent the drill bit from damaging the clutch mechanism 8. The dust cover 12 is used to protect the inside of the lock cylinder. The tooth design on the key 4 can push the upper pin 10 and the lower pin 9 apart to achieve unlocking. The return spring 11 ensures that the pins automatically return to the unlocked state, maintaining the free-spinning state of the lock cylinder.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
