[0017] The present invention will be further explained below with reference to the accompanying drawings and embodiments. However, this explanation should not be construed as limiting the scope of protection of the present invention. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0018] Combined with appendix Figure 1-2 The magnetic retaining locker shown is a type of intelligent electronic lock locking mechanism, comprising a housing 1, a shielded iron pipe 2, a rear plug iron pad 3, a washer 4, an electromagnetic coil 5, a copper pipe 6, a strong magnet 7, a demagnetizing element 7, a spring 9, an iron moving pin 10, and a copper baffle 11.

[0019] The shell 1 is an integral cylindrical structure with an open front end, formed by die casting of zinc alloy. Threaded connection holes are provided on the outer circumference of the front end of the shell 1. The shielding iron pipe 2 is installed inside the shell 1. The shielding iron pipe 2 and the rear end of the shell 1 are respectively provided with cable outlets 13. The rear plug iron pad 3 and the washer 4 are arranged in sequence from back to front inside the rear end of the shielding iron pipe 2. The washer 4 is made of 45# steel.

[0020] The electromagnetic coil 5 is set inside the shielded iron tube 2 through the frame 51, and the rear end face of the frame 51 is attached to the end face of the washer 4; the copper tube 6 is set inside the frame 51 of the electromagnetic coil 5, and the rear end of the copper tube 6 is located in the center hole of the washer 4; the strong magnet 7, the demagnetizing element 7 and the spring 9 are arranged in the rear section of the copper tube 6 from back to front.

[0021] The iron pin 10 has a stepped shaft structure. The iron pin 10 is set in the front section of the copper tube 6. The stepped part at the rear end of the iron pin 10 is matched with the front end of the spring 9. A retaining ring 101 is set on the stepped part at the front end of the iron pin 10. A copper baffle 11 is set on the open front end of the housing 1. A U-shaped opening groove is set on the copper baffle 11. The front end of the iron pin 10 passes through the U-shaped opening groove and matches the U-shaped opening groove of the copper baffle 11 through the stepped part at the front end of the iron pin 10.

[0022] Preferably, the strong magnet 7 is a neodymium iron boron magnet, and the demagnetizing element is a device for the neodymium iron boron permanent magnet when it is not magnetized after sintering. The thickness of the demagnetizing element 7 is set to be greater than the thickness of the strong magnet 7. The demagnetizing element 7 weakens the attraction force of the neodymium iron boron magnet 75%, ensuring that the iron moving pin 10 pops out smoothly after being energized.

[0023] This utility model discloses an intelligent electronic lock locking mechanism using a magnetic retaining lock. During use, when the main bolt is in the locked state, the lock body is in normal working condition. At this time, the electromagnetic coil is not energized, and the iron moving pin 10 is attracted by the strong magnet 7. Furthermore, the iron moving pin 10 is pushed back by the iron moving pin 10 reset mechanism within the lock body against the retaining ring 101. The iron moving pin 10 is in the retracted position, and the retaining ring 101 on the iron moving pin 10 contacts the copper stop plate 11, compressing the spring 9. During lock body use, if the lock is illegally or technically unlocked, the main board detects the key as... When an unverified illegal key is used, the electromagnetic coil is energized when it receives a 200-millisecond high-level signal from the main control circuit of the lock body. This generates a magnetic field, which cancels out the magnetic force of the permanent magnet. Under the action of spring 9, the iron moving pin 10 extends instantaneously to block the large sliding plate from moving downward, thereby preventing the main bolt from continuing to move horizontally to unlock. The main bolt is stopped in position 1, causing the two main bolts to be stuck halfway outside the lock body. This makes illegal or technical unlocking fail and the door cannot be opened, thus achieving the true security function of the electromechanical integrated security mechanism.

[0024] The parts of this utility model not described in detail are existing technologies.

[0025] The embodiments selected herein for the purpose of disclosing the inventive objectives of this utility model are currently considered appropriate; however, it should be understood that this utility model is intended to include all variations and modifications of the embodiments that fall within the scope of this concept and utility model.
