[0002] A gun lock is a special lock for locking the use function of a firearm. For example, the utility model patent with publication number "CN206477692U" and the name "A gun lock that can be started quickly" discloses a gun lock that can be started quickly, including a base plate and a lock cover, a locking plate shaft is vertically arranged in the middle of the upper surface of the base plate, a locking plate is rotatably installed on the upper end of the locking plate shaft, a cylindrical table is used in the middle of the locking plate, a reset coil spring is installed between the cylindrical table and the locking plate, an unlocking bracket is vertically installed on one side of the locking plate shaft, an unlocking plate with one end buckled with the locking plate is horizontally slidably installed on the upper end of the unlocking bracket, a locking opening is arranged on the other side of the locking plate shaft, an arc-shaped locking hook is arranged on the upper part of the locking plate near the locking opening, and the arc-shaped locking hook is arranged on the upper part of the locking plate near the locking opening. The locking hook passes through the side wall of the locking mouth to form a locking structure, an electromagnet is installed horizontally at the rear of the upper end surface of the bottom plate, a restorative telescopic shaft is installed horizontally on one end of the electromagnet close to the unlocking bracket, an electronic lock cylinder is installed vertically on the rear side of the unlocking bracket, an unlocking card is rotatably installed on the electronic lock cylinder, one end of the unlocking card is connected to the restorative telescopic shaft, and the other end is buckled with the unlocking piece, a starting plug that moves left and right is installed on the upper end surface of the locking piece, a protruding buckle is arranged at the front of the lower end of the starting plug, a positioning notch matching the protruding buckle is arranged on the locking piece, and a lock cover covering all parts is installed on the bottom plate. It uses a single arc-shaped locking hook to pass through the trigger hole of the trigger to achieve the purpose of locking the firearm. Due to the use of a single structure of the arc-shaped locking hook and the limitation of the overall external dimensions, the width of the locking mouth cannot be too wide, and precise alignment is required when placing the firearm to put it into the locking mouth, which affects the locking speed. At the same time, it also limits the scope of use of applicable firearms. For example, it can only be used for firearms in a small size range, and the scope of application is narrow.

[0003] To this end, the applicant has developed a double-bolt gun lock and applied for a Chinese utility model patent on June 18, 2023, with the publication number "CN220103875U" and the name "double-bolt gun lock". The patent discloses a double-bolt gun lock, which includes a lock body, a control circuit board, a drive device, a pull gear, a locking gear ring, a movable plate and two arc-shaped lock tongues and other components. Although it can open or close synchronously relative to each other through the use of a double-arc-shaped lock tongue structure design, so as to achieve the problem of widening the width of the locking mouth, after locking, due to the problem of part matching tolerance, the two arc-shaped lock tongues are not very tightly matched, and there is a gap easily, thereby increasing the risk of being pried open and affecting the safety and reliability of the lock. At the same time, when the two arc-shaped lock tongues are opened or closed to the extreme position, if the motor in the drive device fails to stop in time, it is easy to cause damage to components such as gears or may cause damage to the motor due to excessive load, affecting the service life.

[0029] For example, see Figures 1 to 9 The present embodiment provides a self-locking anti-pry smart gun lock, which includes a lock body 1 and a control circuit board 2, a drive device 3, a drive plate 4, a floating frame 5, two lock arms 6 and two maintaining springs arranged in the lock body 1. In the present embodiment, for the convenience of description, the two maintaining springs are respectively referred to as an upper maintaining spring 7 and a lower maintaining spring 8.

[0030] The lock body 1 is provided with a locking opening, and two locking arms 6 are symmetrically arranged at the two sides of the locking opening through a hinge axis. The locking arm 6 includes a locking hook portion 61 and a linkage portion 62 connected in sequence. The locking arm 6 is provided with a hinge hole 63 at the connection between the locking hook portion 61 and the linkage portion 62. The lock body 1 is provided with a hinge shaft matched with the hinge hole 63. The hinge hole 63 of the locking arm 6 cooperates with the hinge shaft on the lock body 1 to realize the flexible rotation of the locking arm 6. Preferably, a locking protrusion is provided at the end of the locking hook portion 61 of one of the locking arms 6, and a locking groove matched with the locking protrusion is provided at the end of the locking hook portion 61 of the other locking arm 6. When the two locking arms 6 are closed, the locking protrusion can be inserted into the locking groove, which has a good bite effect, can further improve the locking effect, and has a good anti-pry effect.

[0031] The lower end of the linkage part 62 extends obliquely toward the lower center line 11 of the locking opening, and the inclination angle at the end position is reduced to form a tensioning part 64. Specifically, the angle a between the linkage part 62 and the center line 11 of the locking opening is 34 to 40 degrees, preferably 37 degrees, and the angle b between the tensioning part 64 and the center line 11 of the locking opening is 2 to 5 degrees, preferably 5 degrees. By setting a specific angle, the linkage part 62 facilitates the two locking arms 6 to open or close synchronously and relatively quickly, and the tensioning part 64 allows the two locking arms 6 to fit more closely when locked, thereby improving the anti-prying ability.

[0032] The linkage part 62 and the tensioning part 64 are respectively provided with a linkage long hole 621 and a tensioning long hole 641 along their extension direction, the linkage long hole 621 and the tensioning long hole 641 are connected, the tensioning parts 64 of the two locking arms 6 are overlapped, the floating frame 5 and the driving plate 4 are overlapped, and are located on the lower center line 11 of the locking mouth, the driving device 3 is located on one side of the driving plate 4, and can drive the driving plate 4 to reciprocate along the center line 11 of the locking mouth. Specifically, the driving device 3 includes a motor 31, a driving gear 32, a transmission gear set and a rack 33. The rack 33 is located on the side wall of the driving plate 4. The driving gear 32 is arranged on the lock body 1 at a position corresponding to the rack 33 and meshes with the rack 33. The motor 31 drives the driving gear 32 to rotate through the transmission gear set. The transmission gear set includes a worm gear 34, a first transmission gear 35, a second transmission gear 36 and a third transmission gear 37. The worm gear 34 is arranged on the rotating shaft of the motor 31. The worm gear 34, the first transmission gear 35, the second transmission gear 36 and the third transmission gear 37 are meshed in sequence. The third transmission gear 37 and the driving gear 32 are coaxially fixedly connected, and the transmission is efficient and stable.

[0033] A linkage protrusion 51 is provided on one surface of the floating frame 5 facing the driving plate 4, and a sliding column 52 passing through two tensioning long holes 641 is provided on the other surface. Since the two tensioning long holes 641 have a certain inclination angle, the further the sliding column 52 moves downward, the tighter the two locking arms 6 will be clamped, and the anti-prying effect will be better.

[0034] A buffer cavity 41 is provided on the driving plate 4 at a position corresponding to the linkage protrusion 51 , and an upper retaining spring 7 and a lower retaining spring 8 are symmetrically arranged at the upper and lower ends of the buffer cavity 41 and relatively press against the linkage protrusion 51 .

[0035] Preferably, a floating magnet is provided on the floating frame 5, and a highest Hall sensor and a lowest Hall sensor are provided on the control circuit board 2 corresponding to the highest rising position and the lowest falling position of the floating magnet. The floating magnet moves up and down with the floating frame 5, and the position of the floating frame 5 is detected by the highest Hall sensor and the lowest Hall sensor to ensure that the lock is correctly locked or unlocked, and the control circuit board 2 controls the motor 31 to stop working in time.

[0036] See also Figure 6 and Figure 7When the two locking arms 6 are closed, if the motor 31 does not stop in time, the driving plate 4 will continue to move downward to compress the upper maintaining spring 7 through the meshing of the driving gear 32 and the rack 33, so as to provide sufficient reaction time for the motor 31. Moreover, even if the motor 31 continues to rotate, due to the limited length of the rack 33, it will automatically separate from the driving gear 32 to disconnect the driving force to avoid damage to the gear or the motor 31 and other components. After the motor 31 stops, under the elastic force of the upper maintaining spring 7, the driving force provided to the floating frame 5 to continue to descend, that is, the floating frame 5 drives the slide column 52 downward, and through the cooperation of the two tensioning long holes 641, the two locking arms 6 can continue to maintain the closing and locking action, and become tighter and tighter, further improving the tightness of the cooperation, improving the anti-pry ability, and ensuring safety.

[0037] See also Figure 8 and Fig. 9 Similarly, when the two locking arms 6 are opened, if the motor 31 does not stop in time, the driving plate 4 will continue to move upward and compress the lower maintaining spring 8 through the engagement of the driving gear 32 and the rack 33, so as to provide sufficient reaction time for the motor 31 and avoid damage to components such as the gear or the motor 31.

[0038] Better, see Figure 1 , Figure 2 , Figure 4 and Fig.10 The self-locking, pry-proof smart gun lock of the utility model is also provided with a mechanical lock core 9. When the electronic system fails, the lock can be unlocked by the mechanical lock core 9 to improve the emergency response capability. Specifically, a mechanical lock core 9 is provided at the position of the lock body 1 corresponding to the slide column 52, and the mechanical lock core 9 is provided with a pull arm 91 that can lift the slide column 52 when rotating. The mechanical lock core 9 cooperates with the slide column 52 through the pull arm 91 to achieve the purpose of mechanical unlocking. Adding a mechanical lock core 9 on the basis of the electronic lock provides double security. Preferably, a bayonet 92 that can clamp the slide column 52 when the slide column 52 is lifted to the highest position is provided at the end position of the pull arm 91. When the slide column 52 slides into the bayonet 92 position, the slide column 52 can be jammed to prevent the slide column 52 from moving downward, which has a stop effect, allowing the two lock arms 6 to remain in an open state, making it convenient to take and put firearms.

[0039] Better, see Figure 1 , Figure 2 and Fig.11The utility model self-locking anti-pry intelligent gun lock is also provided with a feedback device 10, which includes a feedback bullet rack 101, a reset spring 102, a feedback magnet and a feedback Hall sensor. The feedback bullet rack 101 is located at the center line 11 of the locking port. The lower part of the feedback bullet rack 101 is movably extended into the lock body 1 to form an insertion portion. The middle position of the insertion portion is provided with a column avoidance groove 103 to avoid the sliding column 52. The side position of the insertion portion is provided with a presser foot 104. The reset spring 102 is arranged in the lock body 1 and presses on the presser foot 104 to make the upper part of the feedback bullet rack 101 extend into the locking port. The feedback Hall sensor is arranged on the control circuit board 2 corresponding to the position of the feedback magnet. Preferably, an indicator light can also be provided on the control circuit board 2. When there is no firearm, the control circuit board 2 controls the indicator light to emit red light. A lamp hole opposite to the indicator light 22 is provided on the lock body 1. In this way, when no firearm is locked, the indicator light emits red light, indicating an empty state. When a firearm is placed, the feedback magazine 101 is pushed back into the lock body 1, and the feedback magnet moves with the feedback magazine 101. The position of the feedback magnet is detected by the feedback Hall sensor and fed back to the control circuit board 2. The control circuit board 2 connects the locking working circuit of the drive device 3, and the two locking arms 6 are relatively closed to achieve the purpose of automatic locking. At the same time, the control circuit board 2 controls the indicator light to emit green light, indicating that a firearm has been placed, with good indication effect, simple and convenient operation.
