Description

Technical Field

[0001] The present invention relates to the technical field of door bodies, in particular to a high-strength anti-theft door. Background Art

[0002] A door equipped with an anti-theft lock, capable of resisting unauthorized opening under certain conditions for a certain period of time, possesses certain security features and meets the corresponding security level. The full name of the security door is "anti-theft safety door." It combines both anti-theft and security features. According to the "General Technical Requirements for Anti-theft Safety Doors," a qualified security door must be impossible to pry open or create a 615 square millimeter opening in the door leaf within 15 minutes using common hand tools such as chisels, screwdrivers, and crowbars, or portable power tools such as electric drills. Alternatively, a 38 square millimeter opening within a 150 square millimeter semicircle around the locking point must be a special lock with drill resistance that has been tested and approved by relevant authorities. Security doors can be made of various materials, but only those that meet standard testing standards and receive a security product production license can be considered security doors. Based on their structural features, they are mainly classified into sliding gate security doors, swing gate security doors, and plastic embossed security doors. The most widely used security doors are swing gate security doors.

[0003] Although traditional anti-theft doors have a certain anti-theft effect, people can still enter the room by manually prying open the lock and the connection part and removing the lock body from the outside. There is still a lot of room for improvement in its structural strength and anti-theft performance.

[0004] To address the above issues, the invention patent with authorization announcement number CN114737864B discloses a multi-active anti-theft door body. After identification by the fingerprint recognition module, the drive motor is controlled to rotate, and the second gear on the drive motor drives the first gear to rotate, driving the upper and lower racks to move toward the inner panel, and the lock tongues on the upper and lower racks are disengaged from the lock holes on the door frame. This completes the locking between the door panel and the door frame, providing higher security. In the event of a theft, not only the fingerprint recognition module needs to be removed, but also the lock between the upper and lower racks and the door frame. The multiple locking mechanisms further enhance the connection strength between the door panel and the door frame, making removal more inconvenient and improving the anti-theft performance.

[0005] At the same time, the present invention also proposes a new technical solution to solve the above-mentioned problems of insufficient structural strength and anti-theft performance. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the present invention aims to provide a high-strength anti-theft door, aiming to achieve the effect of improving structural strength and anti-theft performance.

[0007] A high-strength anti-theft door comprises an anti-theft door body, the anti-theft door body comprising a door frame and a door panel rotatably disposed within the door frame, the door panel being provided with a mobile power supply, a fingerprint recognition lock, and a fingerprint recognition module, the fingerprint recognition lock being used to lock the door panel relative to the door frame, the fingerprint recognition module being used to control the fingerprint recognition lock, and the mobile power supply being used to provide power to the fingerprint recognition lock and the fingerprint recognition module;

[0008] A driving structure and two locking structures are provided inside the door panel, and the two locking structures are symmetrically arranged on the upper and lower sides of the driving structure;

[0009] The locking structure is used to lock the position of the door panel relative to the door frame, and includes a first inner cavity, a fixed disc and a rotating disc. The first inner cavity is opened inside the door panel, and the fixed disc is fixed to the rear wall of the first inner cavity. The left and right ends of the outer edge of the fixed disc and the end away from the driving structure are provided with a first sliding groove extending toward the position of the center of the fixed disc. The front side surface of the fixed disc is provided with three second sliding grooves, and the three second sliding grooves correspond to the three first sliding grooves one by one. The second sliding grooves are connected to the first sliding grooves and extend in the direction of the first sliding grooves. The cam is fixed on the outer side of the fixed disk and is provided with a central shaft through a bearing. The rotating disk is fixedly sleeved on the outside of the central shaft. The rotating disk is provided with three arcuate through-grooves, and the three arcuate through-grooves correspond to the three second slide grooves respectively. A first plug rod is slidably connected in the first slide groove. One end of the first plug rod passes through the first inner cavity in a sliding connection and passes through the door panel. A sliding rod that slides along the second slide groove is fixed on the outer side wall of the first plug rod. The other end of the sliding rod passes through the arcuate through-groove and moves along the arcuate through-groove.

[0010] The drive structure is used to simultaneously drive the two rotating discs to rotate, and the drive structure includes a cavity, a motor, and a linkage structure. The cavity is opened inside the door panel and is located between the two first inner cavities. The motor is installed in the cavity. The motor is powered by a mobile power supply and controlled by a fingerprint recognition module. The linkage structure is connected between the two rotating discs and is connected to the output shaft of the motor.

[0011] The inner side wall of the door frame is provided with a first insertion hole into which one end of the first insertion rod passing through the door panel can be inserted in a matching connection manner.

[0012] By adopting the above technical solution, after the security door is closed and the door panel is completely positioned within the door frame, each first rod corresponds to each first socket. The fingerprint recognition module activates the motor. The motor's output shaft rotates, driving the linkage mechanism. The linkage mechanism drives the two rotating discs to rotate synchronously. The rotating disc drives the slide rod along the second slide groove through the arc-shaped groove. The slide rod drives the first rod along the first slide groove. The first rod gradually passes through the first slide groove and inserts into the first socket, improving the stability of the connection between the door panel and the door frame, thereby further enhancing the structural strength and anti-theft performance of the security door.

[0013] Preferably, the locking structure also includes three second inner cavities, which are all opened inside the door panel and correspond to three first insertion rods respectively. One end of the first insertion rod that passes through the first inner cavity passes through the second inner cavity, and a slide fixedly sleeved on the outside of the first insertion rod is slidably connected in the second inner cavity. Several second insertion rods are fixed on the slide, and the other end of the second insertion rod passes through the second inner cavity in a sliding connection manner and passes through the door panel. A second socket is opened on the inner side wall of the door frame for the second insertion rod to be inserted in a matching connection manner.

[0014] By adopting this technical solution, when the first rod slides into the first socket, it drives the slide along the second inner cavity. The slide then drives the second rod to slide, allowing it to be inserted into the second socket. The provision of the second socket and the second rod further enhances the stability of the connection between the door panel and the door frame, thereby further improving the structural strength and anti-theft performance of the security door.

[0015] Preferably, sound insulation pads are fixed on the walls of the cavity and the first inner cavity.

[0016] By adopting the above technical solution, the provision of the sound insulation pad can reduce the noise generated by the operation of the motor and the linkage structure.

[0017] Preferably, the linkage structure includes a driven gear, a rotating rod and two worm gears, the two worm gears are respectively fixed to the front sides of the two rotating disks, the rotating rod is rotatably connected between the upper and lower side walls of the cavity through bearings, the upper and lower ends of the rotating rod respectively penetrate into the two first inner cavities, and are both fixed with worms connected to the worm gears, the driven gear is located inside the cavity and is fixedly sleeved on the outside of the rotating rod, and a driving gear meshing with the driven gear is fixed on the output of the motor.

[0018] By adopting the above technical solution, when the linkage structure is required to drive the two rotating discs to rotate simultaneously, the motor is started. The motor's output shaft rotates, driving the driving gear. The driving gear then rotates the meshing driven gear. The driven gear then rotates the rotating rod fixedly connected to it. The rotating rod then rotates the two worms simultaneously. The two worms then rotate the two worm wheels. The two worm wheels then rotate the two rotating discs, respectively. This achieves synchronous rotation of the two rotating discs.

[0019] Preferably, the linkage structure includes a transmission belt and two driven wheels, two through holes are connected between the cavity and the two first inner cavities, the two driven wheels are respectively fixed to the front sides of the two rotating disks, a driving wheel is installed on the output shaft of the motor, the transmission belt is passed through the through hole between the cavity and the two first inner cavities, and is connected to the driving wheel and the two driven wheels.

[0020] By adopting this technical solution, when the linkage structure is required to drive the two rotating discs to rotate simultaneously, the motor is started. The motor's output shaft rotates, driving the driving wheel, which in turn drives the two driven wheels via a transmission belt to rotate simultaneously. The two driven wheels then drive the two rotating discs, respectively, achieving synchronous rotation of the two rotating discs.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention drives two locking structures to operate simultaneously through a driving structure. The locking structure is used to lock the position of the door panel relative to the door frame, thereby improving the connection stability between the door panel and the door frame, thereby further improving the structural strength and anti-theft performance of the anti-theft door body.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1:

[0034] A high-strength anti-theft door, such as Figures 1-6 As shown, the security door comprises a main body. The main body comprises a door frame 1 and a door panel 2 rotatably mounted within the door frame 1. The door panel 2 is provided with a mobile power supply, a fingerprint recognition lock 3, and a fingerprint recognition module. The fingerprint recognition lock 3 is used to lock the door panel 2 relative to the door frame 1. The fingerprint recognition module is used to control the fingerprint recognition lock 3. The mobile power supply is used to provide power to the fingerprint recognition lock 3 and the fingerprint recognition module. The mobile power supply, fingerprint recognition lock 3, and fingerprint recognition module are all mature existing technologies and will not be described in detail here.

[0035] A driving structure and two locking structures are provided inside the door panel 2. The two locking structures are symmetrically arranged on the upper and lower sides of the driving structure.

[0036] The locking structure, used to lock the door panel 2 relative to the door frame 1, includes a first inner cavity 4, a fixed disc 5, and a rotating disc 6. The first inner cavity 4 is defined within the door panel 2. The fixed disc 5 is fixed to the rear wall of the first inner cavity 4. First chute grooves 7 extending toward the center of the fixed disc 5 are defined on both the left and right ends of the outer edge of the fixed disc 5, as well as on the end facing away from the drive structure. Three second chute grooves 8 are defined on the front side of the fixed disc 5. These three second chute grooves 8 correspond one-to-one with the three first chute grooves 7. The second chute grooves 8 are connected to the first chute grooves 7 and extend in the same direction as the first chute grooves 7. Their width is smaller than that of the first chute grooves 7. A central shaft 9 is rotatably connected to the center of the front side of the fixed disc 5 via a bearing. The rotating disc 6 is fixedly mounted on the exterior of the central shaft 9. Three arcuate through-grooves 10 are defined on the rotating disc 6. These three arcuate through-grooves 10 correspond to the three second chute grooves 8, respectively. A first insertion rod 11 is slidably connected within the first chute groove 7. One end of the first insertion rod 11 slides through the first inner cavity 4 and passes through the door panel 2. A sliding rod 12 is fixed to the outer wall of the first insertion rod 11 and slides along the second sliding groove 8. The other end of the sliding rod 12 penetrates the arcuate through groove 10 and moves along the arcuate through groove 10.

[0037] The locking structure also includes three second inner cavities 13. The three second inner cavities 13 are all opened inside the door panel 2 and correspond to the three first insertion rods 11 respectively. The end of the first insertion rod 11 that passes through the first inner cavity 4 passes through the second inner cavity 13. A slide plate 14 fixedly mounted on the outside of the first insertion rod 11 is slidably connected in the second inner cavity 13. A plurality of second insertion rods 15 are fixed on the slide plate 14. The other end of the second insertion rod 15 passes through the second inner cavity 13 in a sliding connection manner and passes through the door panel 2. A first socket 18 is provided on the inner side wall of the door frame 1 for inserting the end of the first insertion rod 11 that passes through the door panel 2 in a mating connection manner, and a second socket 16 is provided for inserting the second insertion rod 15 in a mating connection manner.

[0038] The drive structure is used to simultaneously drive the two rotating discs 6 to rotate. The drive structure includes a cavity 17, a motor, and a linkage structure. Cavity 17 is located within the door panel 2 and between the two first inner cavities 4. The motor is installed in cavity 17. The motor is powered by a mobile power supply and controlled by the fingerprint recognition module. The linkage structure is connected between the two rotating discs 6 and to the output shaft of the motor. The connection between the fingerprint recognition module and the motor is a mature prior art and is not described in detail in this embodiment. Please also refer to the relevant description in the invention patent with authorization announcement number CN114737864B, a multi-active anti-theft door body.

[0039] The linkage structure includes a driven gear 19, a rotating rod 20, and two worm gears 21. The two worm gears 21 are respectively fixed to the front side surfaces of the two rotating disks 6. The rotating rod 20 is rotatably connected between the upper and lower walls of the cavity 17 via bearings. The upper and lower ends of the rotating rod 20 respectively penetrate the two first inner cavities 4 and are fixed with worms 22 that cooperate with the worm gears 21. The driven gear 19 is located inside the cavity 17 and is fixedly mounted on the outside of the rotating rod 20. A driving gear 23 that meshes with the driven gear 19 is fixed to the output of the motor.

[0040] Working principle:

[0041] After closing the security door body and positioning the door panel 2 completely within the door frame 1, each first insertion rod 11 corresponds to each first insertion hole 18. The motor is activated through the fingerprint recognition module. The motor's output shaft rotates, driving the driving gear 23. The driving gear 23 drives the driven gear 19 meshing with it to rotate. The driven gear 19 drives the rotating rod 20 fixedly connected to it to rotate. The rotating rod 20 drives the two worms 22 to rotate simultaneously. The two worms 22 respectively drive the two worm wheels 21 to rotate. The two worm wheels 21 respectively drive the two rotating discs 6 to rotate, thereby achieving synchronous rotation of the two rotating discs 6. The rotating disc 6 drives the sliding rod 12 to move along the second sliding groove 8 through the arc-shaped through groove 10. The sliding rod 12 drives the first insertion rod 11 to move along the first sliding groove 7. The first insertion rod 11 gradually passes through the first sliding groove 7 and is inserted into the first insertion hole 18. When the first insertion rod 11 slides into the first insertion hole 18, it drives the slide plate 14 to slide along the second inner cavity 13. The slide plate 14 drives the second insertion rod 15 to slide, thereby inserting it into the second insertion hole 16. The connection stability between the door panel 2 and the door frame 1 is improved, thereby further improving the structural strength and anti-theft performance of the anti-theft door body.

[0042] Example 2:

[0043] The difference from the first embodiment is that the linkage structure no longer includes the driving gear 23, the driven gear 19, the rotating rod 20, the two worms 22 and the two worm wheels 21. Figure 7 and Figure 8 As shown, it includes a transmission belt 24 and two driven pulleys 25. Two through-holes 26 connect the cavity 17 to the two first inner cavities 4. The two driven pulleys 25 are fixed to the front sides of the two rotating disks 6. A driving pulley 27 is mounted on the output shaft of the motor. The transmission belt 24 passes through the through-holes 26 and is arranged between the cavity 17 and the two first inner cavities 4. It is in transmission connection between the driving pulley 27 and the two driven pulleys 25.

[0044] When the linkage mechanism is required to drive the two rotating discs 6 to rotate simultaneously, the motor is started. The motor's output shaft rotates, driving the driving pulley 27. The driving pulley 27, via the transmission belt 24, drives the two driven pulleys 25 to rotate simultaneously. The two driven pulleys drive the two rotating discs 6, respectively, achieving synchronous rotation of the two rotating discs 6.
