Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to a lock with anti-prying and anti-smashing functions. Background Art

[0002] A lock is a device that seals a door. In addition to being opened with a key, a lock can also be opened with light, electricity, magnetism, sound, fingerprints, and other commands. It is fixed to the door during installation and needs to be removed from the room when it is removed. When some criminals steal or commit crimes indoors, they will open the lock or damage the lock by prying or smashing the lock, and then steal or commit crimes indoors after opening the door.

[0003] However, existing locks have some defects, such as:

[0004] The existing locks cannot promptly remind the owner when the locks are pried or smashed, resulting in the owner being unable to react quickly to warn the criminals to stop prying or smashing the locks. Therefore, the existing locks have the defect of not being able to automatically remind the owner when the locks are pried or smashed.

[0005] Therefore, the utility model provides a lock with anti-pry and anti-smash functions to solve the above problems. Utility Model Content

[0006] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a lock with anti-pry and anti-smash functions to solve the problem that the lock cannot be pried or smashed and cannot automatically remind the owner.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A lock with anti-pry and anti-smashing functions, comprising a shell, a shielding component and a base; the shell: a key sensor is fixed at the lower end of the shell, a voltage sensor, a single-chip microcomputer, a wireless signal transmitter and a lithium battery are fixed in the shell, the output end of the lithium battery is electrically connected to the input end of the single-chip microcomputer, the output end of the single-chip microcomputer is electrically connected to the input end of the wireless signal transmitter, and the output end of the voltage sensor is electrically connected to the input end of the single-chip microcomputer;

[0009] Base: The base is movably inserted into the lower end of the shell, a central support column is movably inserted into the upper side of the base, a second spring is clamped between the central support column and the shell and between the central support column and the base, a support plate is integrally formed at the middle end of the central support column, a first on-off switch is arranged between the support plate and the lower end of the base, the first on-off switch is turned on when the support plate moves up and down, and the positive and negative poles of the first on-off switch are electrically connected to the positive and negative poles of the voltage sensor;

[0010] Shielding assembly: the front half of the shielding assembly shields the front of the key sensor, the rear half of the shielding assembly movably penetrates into the base, and the rear half of the shielding assembly is fixed to the side of the support plate;

[0011] Through the above technical solution, the key sensor is firstly shielded by the shielding component. The key sensor can only be pried open by pulling away the shielding component. When the shielding component is pulled away, the support plate is driven to move up and down, thereby turning on the first on-off switch. The voltage sensor detects that the voltage of the first on-off switch becomes smaller and transmits the signal to the single-chip microcomputer. The single-chip microcomputer transmits the signal to the wireless signal transmitter. The wireless signal transmitter remotely sends the signal to the owner's receiver, so that the owner can know whether someone has pried the lock or opened the lock normally.

[0012] Secondly, when the lock is smashed, the outer shell will be smashed up and down, and the outer shell will drive the central support column to move up and down through the second spring, and the central support column will drive the support plate to move up and down. According to the above, the owner can know that someone has smashed the lock.

[0013] Preferably, the first on-off switch comprises two first contact rings and two second contact rings, the two first contact rings are respectively fixed to the upper and lower sides of the lower end of the housing, the two second contact rings are respectively fixed to the upper and lower sides of the support plate, the support plate and the two second contact rings are located between the two first contact rings, and the first contact ring and the second contact ring are respectively electrically connected to the positive and negative electrodes of the voltage sensor;

[0014] Through the above technical solution, when the shell moves up and down relative to the base, the upper first contact circle contacts the upper second contact circle downward, or the lower first contact circle contacts the lower second contact circle upward, so that the circuit is energized and the circuit voltage decreases instantaneously. When the first contact circle and the second contact circle are separated, the circuit voltage increases instantaneously, thereby realizing the power on and off of the circuit.

[0015] Preferably, the edges of the first and second contact loops on the side close to each other are both provided with notches;

[0016] Through the above technical solution, when the central support column, the support plate, the first electric ring and the second electric ring rotate, the edges of the first electric ring and the second electric ring are in contact, and the notch can be provided to make the notches of the first electric ring and the second electric ring in contact, so as to make the contact area larger, the current smaller, and the voltage value change easier to be detected by the voltage sensor.

[0017] Preferably, the shielding assembly includes a lifting frame, a keyhole shielding bar, a first spring and a connecting plate, the keyhole shielding bar is located directly in front of the key sensor, the two ends of the keyhole shielding bar are movably sleeved with the lifting frame, the first spring is fixed between the lower end of the keyhole shielding bar and the inner lower side of the lifting frame, the side of the lifting frame is fixed with a connecting plate, the connecting plate is movably inserted into the shell, and the end of the connecting plate is fixed to the side of the support plate;

[0018] Through the above technical solution, when the key sensor needs to be triggered by the key, the keyhole shielding bar needs to be pulled up and down. When the keyhole shielding bar moves up and down, the lifting frame will be driven up and down by the first spring, and the first spring itself will be compressed or stretched, and the lifting frame will drive the connecting plate to move up and down, and the connecting plate will drive the supporting plate to move up and down, so that the first contact circle and the second contact circle are in contact, so that the pressure sensor detects that the circuit voltage becomes instantaneous smaller, so that the shielding component is used to let the owner know in time when the lock is pried or unlocked normally.

[0019] Preferably, the end of the connecting plate is fixed to the side of the front half of the supporting plate;

[0020] A central shaft is fixed at both ends of the middle of the connecting plate, the central shaft rotates in the lifting block, and the lifting block moves up and down and is inserted in the lower end of the shell;

[0021] Through the above technical solution, the shielding component moves up and down while moving forward and backward, that is, the shielding component can drive the support plate to rotate, so that not only can it be detected that someone pulls the keyhole shielding bar up and down, but also it can be detected that someone pulls the keyhole shielding bar back and forth, and the safety detection range is wider. The central axis rotates in the lifting block and the lifting block moves up and down in the outer shell, which will not hinder the up and down movement of the support plate.

[0022] Preferably, a torsion spring is fixed between one of the central shafts and the lifting block, one end of the torsion spring is inserted into the central shaft, the other end of the torsion spring is inserted into the lifting block, and the central shaft is located in the torsion spring;

[0023] Through the above technical solution, the torsion spring can drive the central shaft to rotate in the opposite direction and return to its original position after the central shaft rotates.

[0024] The beneficial effects of the utility model are:

[0025] 1. The shielding component blocks the key sensor. The key sensor can only be pried open by pulling the shielding component open. When the shielding component is pulled open, the support plate will be driven to move up and down, thereby turning on the first on-off switch. The voltage sensor detects that the voltage of the first on-off switch becomes smaller and transmits the signal to the single-chip microcomputer. The single-chip microcomputer transmits the signal to the wireless signal transmitter. The wireless signal transmitter remotely sends the signal to the owner's receiver, so that the owner can know whether someone has pried the lock or opened the lock normally.

[0026] Secondly, when the lock is smashed, the shell will be smashed up and down, and the shell will drive the central support column to move up and down through the second spring, and the central support column will drive the support plate to move up and down, so that the first power-on and power-off switch can be opened. The voltage sensor detects that the voltage of the first power-on and power-off switch becomes smaller, and transmits the signal to the single-chip microcomputer. The single-chip microcomputer transmits the signal to the wireless signal transmitter, and the wireless signal transmitter remotely sends it to the owner's receiver, so that the owner can know that someone has smashed the lock.

[0027] 2. In summary, the device can use the up and down movement of the shielding component to know that the key sensor has been pried, and can use the up and down movement of the shell relative to the base to know that the shell has been smashed. In this way, the owner can know that the lock has been pried or smashed, and can promptly notify the property or other personnel to stop it. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following will refer to the attached Figures 1 to 7The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0037] A lock with anti-pry and anti-smash functions, as shown in the attached Figure 1 and attached Figure 2 As shown, it includes a housing 1, a shielding component and a base 5;

[0038] Shell 1: Shell 1 is fixed on the door. A key sensor 4 is fixed at the lower end of shell 1. Key sensor 4 is electrically connected to the electronic lock inside the external door. Figure 4 A voltage sensor 6, a single-chip microcomputer 7, a wireless signal transmitter 8 and a lithium battery 9 are fixed in the housing 1. The output end of the lithium battery 9 is electrically connected to the input end of the single-chip microcomputer 7, and the output end of the single-chip microcomputer 7 is electrically connected to the input end of the wireless signal transmitter 8, that is, the single-chip microcomputer 7 can send a signal through the wireless signal transmitter 8, and the output end of the voltage sensor 6 is electrically connected to the input end of the single-chip microcomputer 7. In addition, the voltage sensor 6 can be replaced by a current sensor or a multimeter;

[0039] Base 5: See attached Figure 4 and attached Figure 5 The base 5 is movably inserted in the lower end of the shell 1, and the base 5 is fixed on the door, and the base 5 is wrapped by the shell 1. If the base 5 is to be damaged, the shell 1 must be damaged first. A central support column 18 is movably inserted in the upper side of the base 5. A second spring 12 is fixedly clamped between the central support column 18 and the shell 1 and between the central support column 18 and the base 5. A support plate 15 is integrally formed at the middle end of the central support column 18. A first on-off switch is provided between the support plate 15 and the lower end of the base 5. When the support plate 15 moves up and down, the first on-off switch is turned on, and the positive and negative poles of the first on-off switch are electrically connected to the positive and negative poles of the voltage sensor 6. The voltage sensor 6 detects whether the first on-off switch is powered on or off.

[0040] Blocking components: See attached Figure 1 , Attachment Figure 4 and attached Figure 5 The front half of the shielding component shields the front of the key sensor 4 , the rear half of the shielding component movably penetrates into the base 5 , and the rear half of the shielding component is fixed to the side of the support plate 15 .

[0041] As attached Figure 5 and attached Figure 7As shown, the first on-off switch includes two first contact loops 13 and two second contact loops 14, the two first contact loops 13 are respectively fixed to the upper and lower sides of the lower end of the housing 1, and the two second contact loops 14 are respectively fixed to the upper and lower sides of the support plate 15, the support plate 15 and the two second contact loops 14 are located between the two first contact loops 13, and the first contact loop 13 and the second contact loop 14 are respectively electrically connected to the positive and negative electrodes of the voltage sensor 6;

[0042] The working steps of the first on-off switch are as follows: when the housing 1 moves up and down relative to the base 5, the upper first contact circle 13 contacts the upper second contact circle 14 downward, or the lower first contact circle 13 contacts the lower second contact circle 14 upward, so that the circuit is energized, so that the circuit voltage decreases instantaneously, and the pressure sensor 6 detects that the voltage decreases; when the first contact circle 13 and the second contact circle 14 are separated, the circuit voltage increases instantaneously, and the pressure sensor 6 detects that the voltage increases.

[0043] As attached Figure 6 and attached Figure 7 As shown, the edges of the first and second switching rings 13 and 14 on the side close to each other are both provided with notches.

[0044] As attached Figure 1 , Attachment Figure 5 , Attachment Figure 6 and attached Figure 7 As shown, the shielding assembly includes a lifting frame 2, a keyhole shielding bar 3, a first spring 10 and a connecting plate 19. The keyhole shielding bar 3 is located directly in front of the key sensor 4. The two ends of the keyhole shielding bar 3 are movably sleeved with the lifting frame 2. The first spring 10 is fixed between the lower end of the keyhole shielding bar 3 and the inner lower side of the lifting frame 2. The side of the lifting frame 2 is fixed with a connecting plate 19, which is movably inserted into the housing 1, and the end of the connecting plate 19 is fixed to the side of the support plate 15.

[0045] The working steps of the shielding component are as follows: when the key sensor 4 needs to be triggered by the key, the keyhole shielding bar 3 needs to be pulled up and down. When the keyhole shielding bar 3 moves up and down, the lifting frame 2 will be driven up and down by the first spring 10, and the first spring 10 itself is compressed, and the lifting frame 2 drives the connecting plate 19 to move up and down, and the connecting plate 19 drives the supporting plate 15 to move up and down, so that the first contact circle 13 and the second contact circle 14 are in contact, and according to the working steps of the first on-off switch, the pressure sensor 6 detects that the circuit voltage is instantaneously reduced, and when the keyhole shielding bar 3 is released, the second spring 12 pushes back the supporting plate 15 to separate the first contact circle 13 and the second contact circle 14, and according to the working steps of the first on-off switch, the pressure sensor 6 detects that the circuit voltage is instantaneously increased, and the supporting plate 15 pushes back the connecting plate 19, and the connecting plate 19 pushes back the lifting frame 2, and the lifting frame 2 pushes the keyhole shielding bar 3 through the first spring 10, and the first spring 10 itself stretches and deforms to push back the keyhole shielding bar 3.

[0046] As attached Figure 5 and attached Figure 7 As shown, the end of the connecting plate 19 is fixed to the front half side of the supporting plate 15;

[0047] The center shaft 16 is fixed to both ends of the middle of the connecting plate 19 . The center shaft 16 rotates in the lifting block 17 . The lifting block 17 is inserted into the lower end of the housing 1 and moves up and down.

[0048] As attached Figure 5 and attached Figure 7 As shown, a torsion spring 11 is fixed between one of the center shafts 16 and the lifting block 17, one end of the torsion spring 11 is inserted into the center shaft 16, and the other end of the torsion spring 11 is inserted into the lifting block 17. The center shaft 16 is located in the torsion spring 11. After the connecting plate 19 drives the support plate 15, the center support column 18 and the center shaft 16 to rotate, the restoring deformation ability of the torsion spring 11 and the second spring 12 will drive the support plate 15, the center support column 18 and the center shaft 16 to rotate in the opposite direction.

[0049] When using this device:

[0050] The shielding component shields the key sensor 4. The owner or the criminal pulls the shielding component up and down or forward and backward to pry open the key sensor 4. When the shielding component is pulled open, the support plate 15 is driven to move up and down or rotate, thereby turning on the first on-off switch. At this time, the voltage sensor 6 detects that the voltage of the first on-off switch becomes smaller, and transmits the signal to the single-chip microcomputer 7. The single-chip microcomputer 7 transmits the signal to the wireless signal transmitter 8. The wireless signal transmitter 8 remotely sends the signal to the owner's receiver, and the owner can know that someone has pried the lock or opened the lock normally.

[0051] When the criminals forcibly smash the shell 1 up and down, the shell 1 moves up and down. At this time, the shell 1 drives the central support column 18 to move up and down through the second spring 12, and the central support column 18 drives the support plate 15 to move up and down, so that the first on-off switch can be turned on. At this time, the voltage sensor 6 detects that the voltage of the first on-off switch becomes smaller, and transmits the signal to the single-chip microcomputer 7. The single-chip microcomputer 7 transmits the signal to the wireless signal transmitter 8, and the wireless signal transmitter 8 remotely sends it to the owner's receiver, so that the owner can know that someone has smashed the lock;

[0052] This allows the owner to know that someone has opened, pried or broken the lock normally.
