DETAILED DESCRIPTION
[0056] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.
[0057] Most of the boat locks on the market are currently formed in one piece at the factory and cannot be disassembled. In addition, the existing boat locks do not have an electronic alarm function before leaving the factory. Boat locks without an electronic alarm function are still easy to be pried open or smashed open without being discovered in unattended places, and cannot immediately scare away thieves. Their anti-theft performance is relatively poor; if the user wants to add an electronic alarm device to the lock body, the modification cost is relatively high.
[0058] In order to solve the above problem, this embodiment provides a lock capable of alarming, including:
[0059] a lock body having a cavity;
[0060] The lock core is arranged in the cavity; the lock core is provided with a first lock hole, and the first lock hole is used to insert a key to drive the lock core to move;
[0061] A first sensing component is provided on the lock core;
[0062] A second sensing component is provided on the lock body, and when the first sensing component moves relative to the second sensing component, the first sensing component or the second sensing component generates an electrical signal;
[0063] The alarm component is arranged on the lock body and is connected to the first sensing component or the second sensing component. The alarm component alarms according to the electrical signal.
[0064] The first sensing component is arranged on the lock cylinder and can move synchronously with the lock cylinder; in this embodiment, the key is inserted into the lock cylinder to drive the lock cylinder to rotate. In some embodiments, the space in the cavity can be expanded to provide space for the lock cylinder to move in translation or other ways, and the key is inserted into the lock cylinder to drive the lock cylinder to move in translation or other ways, ensuring that the first sensing component can be relatively displaced with the second sensing component.
[0065] In this embodiment, the first sensing component is used to transmit signals, and the second sensing component is used to receive signals. The second sensing component generates a corresponding electrical signal according to the received transmitted signal, thereby triggering the alarm component to sound an alarm.
[0066] In some embodiments, the first sensing component can be used to receive signals, and the second sensing component can be used to transmit signals. The first sensing component generates a corresponding electrical signal based on the received transmitted signal, thereby triggering the alarm component to sound an alarm.
[0067] Specifically, Figures 1 to 12 As shown, this embodiment provides a lock capable of sounding an alarm, which includes a lock body, a lock core, a first sensing component 4, a second sensing component and an alarm component; wherein the lock body includes a lock head 3 and a base 2.
[0068] like Figure 3-4As shown, the lock 3 includes a lock cover 8, a first lock part 31 and a second lock part 32. The diameter of the first lock part 31 is larger than that of the second lock part 32. The lock cover 8 is clamped on the first bottom surface of the first lock part 31. The lock cover 8 is provided with an opening for inserting a key. The second lock part 32 is fixed on the second bottom surface of the first lock part 31. A cavity 34 is provided in the lock 3. The cavity 34 axially penetrates the first lock part 31 and the second lock part 32 for accommodating a lock core. A first pin hole 33 is provided on the side wall of the second lock part 32. The first pin hole 33 extends radially and passes through the cavity 34 for accommodating a lock core, so that the internal space of the first pin hole 33 partially intersects with the internal space of the cavity 34.
[0069] A hole groove 35 is provided on the bottom surface of the end of the second lock portion 32. The hole groove 35 is located opposite to the cavity 34 for accommodating the lock core and is connected to the cavity 34. The hole groove 35 is set as an incomplete circular structure. The area of the hole groove 35 is smaller than the area of the same circle, which is used to limit the rotation angle of the lock core.
[0070] In this embodiment, the cavity 34 is located on one side of the radial center line of the lock head 3, providing sufficient space for the first pin hole 33, so that the first pin hole 33 crosses the radial center line of the second lock part 32, making full use of the limited space in the lock head 3.
[0071] A lock core is provided in the cavity 34 of the lock head 3, and a first lock hole 71 is provided on a side of the lock core facing the lock cover 8. The position of the first lock hole 71 faces the opening position of the lock cover 8, so that the key can be inserted into the first lock hole 71 to drive the lock core to move. In this embodiment, the rotation of the key can drive the lock core to rotate in the cavity 34 of the lock head 3. The rotation angle is determined by the hole groove 35 on the bottom surface of the end of the second lock part 32. In this embodiment, the hole groove 35 is set to three quarters of the area of a circle, and a limit block 54 is provided on a side of the lock core facing the bottom surface of the end of the second lock part 32. The limit block 54 is inserted into the hole groove 35. When the lock core rotates, when the limit block 54 abuts against any edge of the hole groove 35, the lock core reaches the maximum rotation angle in the rotation direction.
[0072] like Fig. 9 , Fig.10As shown, in this embodiment, the lock core includes a lock housing 7, a lock core 5 and a plurality of lock pieces 6; a first lock hole 71 is provided on the lock housing 7, one end of the lock core 5 is inserted into the lock housing 7, and a cavity is formed between the lock core 5 and the lock housing 7, and the cavity is used to accommodate a plurality of lock pieces 6. A second lock hole 62 is provided at the central position of each lock piece 6, and a plurality of lock pieces 6 are stacked together and placed in the cavity together, and the second lock holes 62 of all lock pieces 6 are aligned to form a key channel for inserting a key; some lock pieces 6 have the same locking pieces 61 extending outward in the same direction, and when all the lock pieces 6 are stacked together, the locking pieces 61 in the same direction are used to be stuck between the two pressing pieces of the lock core 5, so that the rotation of the lock piece 6 is synchronized with the rotation of the lock core 5.
[0073] The lock core 5 includes a first lock core part 51 and a second lock core part 53. A first groove 52 is provided on the peripheral side of the first lock core part 51, and the first groove 52 can be a semicircular groove. The second lock core part 53 is composed of two pressing plates surrounding the edges of the first lock core part 51. Each pressing plate can be set to an arc surface structure so that the second lock core part 53 can be fully inserted into the lock shell 7 and fit tightly against the inner wall of the lock shell 7. At this time, the lock plate 6 is inserted into the cavity formed between the pressing plate and the lock shell 7, and the unlocking and locking states can be switched after the key is inserted.
[0074] The unlocking and locking state switching of this embodiment is realized by the cooperation between the lock core and the lock pin 9. The lock pin 9 is formed by high-strength stainless steel. Figure 8 As shown, the diameter of the bottom of the lock pin 9 is less than or equal to the diameter of the first pin hole 33 so that the lock pin 9 can be inserted into the first pin hole 33. Two symmetrical second grooves 91 can be set on the cylindrical circumferential side of the lock pin 9, and the second grooves 91 can be semicircular or annular grooves. A first pin hole 33 is provided on the side wall of the lock head 3, and the lock pin 9 can be inserted into the first pin hole 33 of the lock head 3. When the second groove 91 on the lock pin 9 is engaged with the column body of the first lock core part 51 of the lock core 5, the lock pin 9 can be locked, and the lock pin 9 cannot be taken out at this time, achieving the locking effect; at this time, when the lock core 5 is rotated so that the first groove 52 on the column body of the first lock core part 51 is opposite to the second groove 91 on the lock pin 9, the engaging state between the two is released, and the lock pin 9 can be taken out from the first pin hole 33 of the lock head 3 at this time, achieving the unlocking effect.
[0075] Among them, the first pin hole 33 extends radially in the lock head 3, passes through the cavity 34 axially extending in the lock head 3 for accommodating the lock core, and the internal space of the first pin hole 33 partially intersects with the internal space of the cavity 34; at this time, it is assumed that the first pin hole 33 and the first lock core part 51 are projected along the axial opening direction of the first pin hole 33, and in the axial opening direction of the first pin hole 33, the projection surface of the first pin hole 33 is the first projection surface; the first lock core part 51 is projected along the axial opening direction of the first pin hole 33 to obtain the second projection surface; when the lock pin 9 is not inserted into the first pin hole 33, if the first projection surface corresponding to the first pin hole 33 partially overlaps with the second projection surface corresponding to the first lock core part 51, the space in the first pin hole 33 is blocked by the column body of the first lock core part 51, so that the lock pin 9 cannot be inserted into the first pin hole 33. The first lock core part 51 is continuously rotated. When the first lock core part 51 is rotated to a position where the first groove 52 thereof faces the first pin hole 33, the first projection surface corresponding to the first pin hole 33 and the second projection surface corresponding to the first lock core part 51 do not overlap at all. At this time, the space inside the first pin hole 33 is not blocked, and is sufficient for the lock pin 9 to be inserted into the first pin hole 33. When the lock pin 9 is inserted into the first pin hole 33, the first lock core part 51 is continuously rotated. The second projection surface corresponding to the first lock core part 51 and the first projection surface corresponding to the first pin hole 33 partially overlap. At this time, the column of the first lock core part 51 can be inserted into the second groove 91 of the lock pin 9. At this time, the lock pin 9 cannot be removed from the first pin hole 33, and the locked state is achieved.
[0076] The function of the lock core in the lock is to rotate synchronously with the rotation of the key after the key is inserted. During the rotation process, it cooperates with the lock pin 9 to achieve the unlocking and locking effects of the lock, and can also drive the first sensing component 4 installed at the tail end of the lock core to rotate synchronously.
[0077] In some embodiments, Fig.15 , Fig.16 As shown, the lock core can also be a digital lock or a pin lock or other structures to achieve rotation, and the first groove 52 and the lock pin 9 are not Fig.15 , Fig.16 The bid was Fig.15 as well as Fig.16 They are structural schematic diagrams of a digital lock and a pin lock, which have been disclosed in the prior art. The digital lock and the pin lock structure are not described in detail here. It is only necessary that they can be rotated under the action of a key, and during the rotation process, they can cooperate with the lock pin 9 to realize unlocking and locking, and at the same time, they can drive the first sensing component 4 to rotate synchronously.
[0078] A first sensing component 4 is provided at the end of the lock core. In this embodiment, a first sensing component 4 is also provided at the tail end of the first lock core portion 51 . The first sensing component 4 rotates synchronously with the first lock core portion 51 .
[0079] like Figure 2 As shown, the base 2 is detachably mounted on the lock 3. The base 2 adopts a modular design. When a special situation occurs in the parts of the base 2, the base 2 can be removed from the lock 3 for replacement. Friction lines can also be provided on the outer wall of the base 2. The outer wall of the base 2 contacts the inner wall of the end of the lock 3 through the friction lines. The friction between the base 2 and the lock 3 is increased through the friction lines to prevent the base 2 from falling off the lock 3 easily.
[0080] A second sensing component is provided in the base 2, and the second sensing component corresponds to the first sensing component 4. If the first sensing component 4 is used to transmit signals, the second sensing component is used to receive signals. The second sensing component is built into the base 2, so the second sensing component remains stationary when the base 2 is installed. The first sensing component 4 rotates with the rotation of the key, so that a relative displacement occurs between the first sensing component 4 and the second sensing component. The unlocking / locking state of the lock body is identified according to the relative displacement, and the alarm component is controlled to perform a corresponding operation.
[0081] The first sensing component 4 may be a magnetic field transmitting device, used to transmit a magnetic field within a specified range; in order to ensure that the first sensing component 4 can operate normally for a long time, the first sensing component 4 in this embodiment may be a magnet, which can generate a magnetic field within a certain range for a long time without power supply. The second sensing component is a magnetic field receiving device, used to sense the magnetic field and generate a corresponding electromagnetic signal; when the first sensing component 4 rotates with the lock core, the second sensing component can recognize the change in the strength of the magnetic field, and thus sense the activity of the lock core according to the size of the received electromagnetic signal, thereby determining whether the lock is in an unlocked / locked state.
[0082] In some embodiments, the first sensing component 4 can be a magnetic field receiving device, the second sensing component is a magnetic field transmitting device, the first sensing component 4 rotates with the rotation of the lock core, and the second sensing component is fixed in the base 2; it is only necessary to ensure that the first sensing component 4 and the second sensing component can achieve relative displacement.
[0083] In order to simplify the internal components of the lock, this embodiment adopts an induction method in which the first induction component 4 is a magnetic field transmitter and the second induction component is a magnetic field receiver, so that the second induction component can be electrically connected to other electronic components inside the base 2.
[0084] A central control circuit board is provided in the base 2, and an alarm component is also provided on the base 2, and the alarm component includes a speaker 21 and a vibration sensor. The speaker 21 has a sound port exposed outside the base 2, and is used to play an alarm message to the outside; the central control circuit board is electrically connected to the second sensing component and the alarm component. After receiving the electromagnetic signal collected by the second sensing component, the central control circuit board analyzes whether the lock is currently in an unlocked or locked state according to the strength of the electromagnetic signal, and then controls the switch state of the alarm component according to the unlocked / locked state.
[0085] The vibration sensor is electrically connected to the central control circuit board. When the alarm component is in the on state, the vibration sensor is used to determine whether the lock is currently in a damaged state, thereby determining whether the alarm component needs to send out an alarm sound through the speaker 21.
[0086] For example, when the first sensing component 4 rotates away from the second sensing component, the magnetic field emitted by the first sensing component 4 collected by the second sensing component is relatively weak, and the lock is in the unlocked state. At this time, the central control circuit board controls the alarm component to be in the closed state, and the anti-theft alarm is released. At this time, even if the vibration sensor detects external force vibration or collision, the alarm component will not sound an alarm. When the first sensing component 4 rotates close to the second sensing component, the magnetic field emitted by the first sensing component 4 collected by the second sensing component is relatively strong, and the central control circuit board controls the alarm component to be turned on. If the vibration sensor does not detect external force vibration or collision at this time, the alarm component is controlled to be in a no-alarm state; if the vibration sensor detects external force vibration or collision at this time, the central control circuit board controls the alarm component to sound a continuous alarm through the speaker 21.
[0087] A battery is also built into the base 2, and the battery provides power to the central control circuit board to ensure that the second sensing component, the alarm component and the vibration sensor can operate normally. When the battery needs to be replaced or the electronic components in the base 2 fail, the entire base 2 with a modular design can be removed for replacement, which improves convenience.
[0088] In the lock of this embodiment, the lock core is moved by the key, and the first sensing component 4 is driven to move synchronously when the lock core moves, while the second sensing component is fixed at the end of the lock head 3, and the second sensing component is fixed. When the first sensing component 4 moves, a relative displacement occurs between the first sensing component 4 and the second sensing component. The second sensing component determines the switch and alarm state of the alarm component by identifying the relative displacement, so that the lock itself has an alarm function, thereby improving the safety of the lock.
[0089] In another embodiment, a ship lock is also provided. Fig.13 , 14 As shown, the ship lock includes the above-mentioned alarm lock and a lock tube 1, and the lock tube 1 has a lock cavity.
[0090] A second pin hole 11 is provided on the side wall of the lock tube 1, and a long slot 12 is provided on the axial side wall of the lock tube 1. The interior of the lock tube 1 is a lock cavity, and one end of the lock tube 1 is set as a closed port, and the other end is set as an open port. In the actual assembly process, the lock handle on the ship lock engine is first inserted into the lock cavity from the open port of the lock tube 1 and clamped into the long slot 12, so that the lock handle on the ship lock engine is limited in the lock cavity of the lock tube 1, and then the lock tube 1 is sleeved on the end of the lock head 3 from the open port of the lock tube 1. At this time, the second pin hole 11 on the lock tube 1 is opposite to the first pin hole 33 on the lock head 3. The lock pin 9 is inserted into the second pin hole 11 and the first pin hole 33 and the key is turned to clamp the lock core and the lock pin 9, so as to achieve the locking effect.
[0091] The combined structure of the lock head 3, lock pin 9 and lock tube 1 in this embodiment has the characteristics of simple structure, simple and reasonable use and convenient disassembly, which is different from the traditional integrated boat lock; the base 2 is included in the lock, and various electronic components are built into the base 2, which can give the boat lock an alarm function; the base 2 adopts a modular design, which is more convenient and quick to repair, replace or charge, so that the boat lock has the effect of being safe and not easy to be damaged.
[0092] The connection relationship and functions of the various components in the boat lock of the embodiment of the utility model can be found in the corresponding description of the above-mentioned lock, which will not be repeated here.
