DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0026] The present invention provides: a lock core and a lock with high anti-theft performance, such as Figure 1-Figure 6 As shown, it includes a lock core housing 1, a rotating pin block 16 is rotatably installed in the middle of the lock core housing 1, and a group of inner cores 22 are respectively installed at both ends of the rotating pin block 16 inside the lock core housing 1. The lock core housing 1 and the rotating pin block 16 are used to limit the two groups of inner cores 22 so that the two groups of inner cores 22 can be used synchronously;

[0027] A group of protective tubes 28 are sleeved on the outside of each group of inner cores 22, and a group of through holes 29 are opened in the middle of each group of protective tubes 28. The inner core 22 is provided with a reinforced lock hole 24 at the position corresponding to the through holes 29, and the lock core shell 1 is provided with a group of reinforced holes 4 at the position corresponding to each group of through holes 29. The protective tubes 28 sleeved on the outside of the inner core 22 protect the outer end of the inner core 22 to prevent the inner core 22 from being damaged when it is subjected to external impact, and the reinforced lock hole 24 and the through hole 29 can limit and store the cylindrical plug rod 14, so that the cylindrical plug rod 14 can rotate as a whole with the inner core 22, thereby better improving the stability of the use of the inner core 22;

[0028] A set of limiting tubes 8 are installed in each set of reinforcement holes 4, and a set of telescopic rods 10 are elastically arranged at the bottom of each set of limiting tubes 8. A set of cylindrical plug rods 14 are magnetically attracted at the lower part of each set of telescopic rods 10. The cylindrical plug rods 14 are movably inserted into the reinforcement lock holes 24. The limiting tubes 8 installed in the reinforcement holes 4 limit the telescopic rods 10. The telescopic rods 10 are pushed by the force springs 13 to move the connecting blocks 12 downward, so that the strong magnets 15 embedded in the top of the cylindrical plug rods 14 are adsorbed on the connecting blocks 12, thereby ensuring that the telescopic rods 10 are locked. The use position of the fixed cylindrical plug rod 14 is made so that the cylindrical plug rod 14 is pressed downward against the key hole. The non-corresponding key cannot lift the cylindrical plug rod 14 and retract it into the reinforced lock hole 24, so that the inner core 22 cannot rotate as a whole, thereby improving the overall anti-theft performance of the lock body. When the corresponding key is used, a protrusion is provided at the corresponding position of the cylindrical plug rod 14, which can completely push the cylindrical plug rod 14 into the reinforced lock hole 24. When the inner core 22 is rotated, the cylindrical plug rod 14 can be driven to rotate, thereby completing the rotation of the inner core 22 to realize the unlocking work.

[0029] Preferably, a middle groove 2 is opened in the middle of the lock core shell 1, and a rotating pin block 16 is rotatably installed inside the middle groove 2. A plurality of groups of limiting holes 3 are opened on the upper part of the lock core shell 1 corresponding to the installation positions of each group of inner cores 22. Each group of reinforcement holes 4 is opened on the outside of the two groups of limiting holes 3 respectively. A group of limiting grooves 5 are opened inwardly at each end of the lock core shell 1. The middle groove 2 opened in the middle of the lock core shell 1 limits the rotating pin block 16, and the set rotating pin block 16 can ensure that the middle grooves 2 on both sides of the lock core shell 1 can be used stably to drive the rotating pin block 16 to rotate as a whole. In addition, the limiting holes 3 opened on the outside of the lock core shell 1 limit the elastic component 6 and the pin 7, and the limiting grooves 5 opened inwardly at both ends of the lock core shell 1 can ensure the stable insertion of the protective tube 28, thereby improving the safety of the overall use of the inner core 22.

[0030] It is worth mentioning that an elastic component 6 is filled in the limiting hole 3, and a group of pins 7 is elastically installed at the bottom of each group of elastic components 6. Each group of pins 7 is elastically inserted into the corresponding inner core 22. A connecting lock cap 9 is threadedly installed on the top of the limiting tube 8, and the connecting lock cap 9 is threadedly installed with the telescopic top end of the telescopic rod 10. A group of limiting plates 11 are bolted and installed at the bottom of each group of telescopic rods 10. A group of connecting blocks 12 are fixedly installed at the bottom of each group of limiting plates 11. A group of force springs 13 are fixedly installed on the upper part of each group of limiting plates 11, and the top of the force spring 13 elastically contacts the inner wall of the limiting tube 8. The set elastic component 6 ensures the elasticity of the pins 7 so that the pins 7 can retract after the key is inserted to ensure the sensitivity of the key when unlocking the lock. The set limiting tube 8 limits the connecting lock cap 9, and the connecting lock cap 9 is bolted to the telescopic top end of the telescopic rod 10, which can better ensure that the telescopic rod 10 moves downward under the thrust of the force spring 13, thereby cooperating with the strong magnet 15 to adsorb the cylindrical plug 14.

[0031] Specifically, a group of strong magnets 15 are embedded and installed on the top of each group of cylindrical plug rods 14. The cylindrical plug rods 14 are movably installed in the reinforced lock hole 24. The cylindrical plug rods 14 are movably adsorbed and installed with the connecting block 12 through the strong magnets 15. The strong magnets 15 embedded and installed on the top of the cylindrical plug rods 14 can ensure the flexible connection between the cylindrical plug rods 14 and the connecting block 12. When the inner core 22 rotates, the adsorption state can be twisted off to ensure normal unlocking. After the key is pulled out and the door is locked, it can be ensured that the telescopic rod 10 is pushed out by the force spring 13 to press down the connecting block 12 to complete the adsorption with the cylindrical plug rod 14, fix the position of the cylindrical plug rod 14, prevent other keys from unlocking, increase the difficulty of unlocking the lock core, and improve the anti-theft performance.

[0032] It is worth noting that a group of side grooves 17 are respectively opened at the two ends of the rotating pin block 16 corresponding to the positions of each group of inner cores 22, and a keyhole 18 is opened through the middle of the side grooves 17 on both sides. Two groups of arc plates 19 are symmetrically installed around the keyhole 18 inside each side groove 17. The side grooves 17 opened at both ends of the rotating pin block 16 can connect the two groups of inner cores 22, so that the inner core 22 on each side can control the rotation of the rotating pin block 16, and the keyhole 18 opened in the middle of the side groove 17 can ensure the accurate insertion of the key, thereby better controlling the rotation of the rotating pin block 16.

[0033] In addition, a group of annular plates 20 are installed in the middle of each group of arc plates 19, and a group of one-way positioning plates 21 are embedded in each group of annular plates 20. The one-way positioning plates 21 extend upward to block the internal path of the arc plates 19. The annular plates 20 installed in the middle of the arc plates 19 limit the one-way positioning plates 21. Each group of one-way positioning plates 21 has a group of extended positions to block the movement of the plug rod 26, thereby ensuring that the plug rod 26 is inserted into the annular plate 20 to complete the control of the rotating pin block 16.

[0034] In addition, an insertion hole 23 is provided on the outer arc surface of the inner core 22 at a position corresponding to the limit hole 3, and a group of key slots 25 are embedded and installed inside each group of inner cores 22, and each group of insertion holes 23 penetrates into the inside of the key slots 25. Two groups of insertion rods 26 are respectively installed on one side of the rotating pin block 16 of the two groups of inner cores 22. The end surface of the key slot 25 is located outside each group of insertion rods 26 and a group of contact springs 27 are fixedly installed. The insertion hole 23 provided on the outer arc surface of the inner core 22 can ensure the insertion and use of the pin 7. The installed insertion rod 26 can be used in conjunction with the arc plate 19 installed inside the rotating pin block 16. After inserting the key, it is necessary to apply force inward to make the insertion rod 26 insert the arc plate 19 and rotate it to ensure that the insertion rod 26 moves with the arc plate 19 to contact the one-way positioning plate 21, so that the one-way positioning plate 21 is subjected to force to complete the control of the rotating pin block 16. When the key is inserted alone and not pushed in, the end of the key cannot be fully inserted into the keyhole 18. At this time, the door lock cannot be opened by rotating the lock core, thereby better improving the anti-theft performance of the door lock.

[0035] Preferably, the end of the insertion rod 26 is elastically inserted into the arc plate 19, and the outer end of each group of contact springs 27 elastically contacts the outer surface of the arc plate 19. Each group of insertion rods 26 rotates to fit the surface of the one-way positioning plate 21, which can ensure that the inner core 22 can move inside the lock core shell 1 to ensure the safety of the inner core 22 during use.

[0036] Specifically, an outer protective rubber pad 30 is installed at the outer end of each group of perforations 29, the protective tube 28 is inserted into the inner wall of the limiting groove 5, the outer protective rubber pad 30 is installed in line with the inner wall of the limiting groove 5, and the perforations 29 are arranged corresponding to the reinforcement holes 4. The outer protective rubber pad 30 can serve the purpose of dust prevention and protection, and avoid directly extending into the interior of the lock core housing 1 from the outside to block the adsorption state of the cylindrical plug rod 14 and the connecting block 12.

[0037] A lock with high anti-theft performance comprises the lock core with high anti-theft performance.
