Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1-9, an electronic lock with prevent function of external strong magnetic interference, including a lock shell 1, set up mechanical lock subassembly and electronic lock subassembly in lock shell 1, mechanical lock subassembly include lock core 2 and be connected with lock core 2 and stretch out to lock shell 1 outer operating parts 3 (preferred knob), electronic lock subassembly include electronic lock control assembly and electromagnetic switch 4 of being connected with electronic lock control assembly electricity, lock core 2 on seted up locked groove 5, switch lever 6 on the electromagnetic switch 4 can stretch into locked groove 5 in and with lock core 2 form the locking cooperation, lock shell 1 in still be equipped with the theftproof locking part 7 that has the function of preventing external strong magnetic interference, theftproof locking part 7 that has the function of preventing external strong magnetic interference including elasticity spacing end 8 and activity locking end 9, elasticity spacing end 8 can receive the drive of outside magnetic path and drive activity locking end 9 stretch into lock end 9 the lock end of preventing to The lock cylinder 2 is locked in the lock groove 5.
The elastic limit end 8 is connected with the lock shell 1 or the switch shell of the electromagnetic switch 4 through an elastic piece. Preferably, the elastic member is a spring 10. Through the setting of spring 10 for the amount of exercise of elasticity spacing end 8 mainly comes from the variable of spring 10, with the deformation of minimize has the theftproof locking piece 7 self of preventing the strong magnetic interference function in outside, thereby can use the back for a long time, still keep good operating mode.
In order to facilitate the installation and use of the spring 10, a support member 11 is arranged on one side of the switch shell of the electromagnetic switch 4, which is far away from the lock slot 5, one end of the spring 10 is connected with the support member 11, and the other end is connected with the elastic limit end 8.
In this embodiment, a guide 12 is further disposed in the lock case 1, and the anti-theft locking member 7 having the function of preventing external strong magnetic interference and the guide 12 form a contact connection. When the external magnetic part acts, the anti-theft locking part 7 with the function of preventing the external strong magnetic interference regularly warps and deforms through the arrangement of the guide part 12, so that the normal working state can be ensured, and the situation that the deformation is excessive and cannot be restored is prevented or reduced.
Because the utility model discloses an in the structure, spacing end 8 of elasticity and activity locking end 9 all do not all belong to fixed connection, consequently all have certain amount of exercise, in order to make the function that has the theftproof locking piece 7 of preventing outside strong magnetic interference function more stable, need carry out special injecing to its movement track. A preferred structure is provided herein: namely, the guide member 12 is disposed near the movable locking end 9, and the end face of the guide member 12 near the end of the anti-theft locking member 7 having the function of preventing the external strong magnetic interference is a guide end face 13, and the guide end face 13 is gradually inclined and downwardly disposed from the elastic limit end 8 to the movable locking end 9. The specific application of this preferred structure is as follows: when the external magnetic block is not close to the lockset, the anti-theft locking piece 7 with the function of preventing external strong magnetic interference is in an initial state, the stress of each end is kept balanced, and the movable locking end 9 is positioned outside the locking groove 5, so that the anti-theft locking piece 7 with the function of preventing external strong magnetic interference cannot interfere with the lock cylinder 2, and the lock cylinder 2 can only be limited by the switch rod 6 of the electromagnetic switch 4; when outside magnetic path is close to the tool to lock, electromagnetic switch 4's switch lever 6 receives the magnetic force influence and withdraws from locked groove 5, has the theftproof locking piece 7 of preventing outside strong magnetic interference function simultaneously and also takes place the displacement, through the effect of the direction terminal surface 13 of special slope setting for the spacing end 8 of elasticity sticks up, and movable locking end 9 pushes down simultaneously and gets into to realize the locking function in locked groove 5, resumes to the locking state of conventional electronic lock tool to lock this moment, the user will electronic lock subassembly unblock back, but lock core 2 free run.
Preferably, the guide 12 and the lock case 1 are integrally formed, so that the time and labor are saved, and the strength is high. Of course, the guide 12 may be formed separately from the lock housing 1 and then assembled together by the connection relationship, and the process difficulty in the design and production process of the separate forming method is reduced, but the assembly difficulty is also increased.
In this embodiment, two sides of the locking groove 5 are provided with a limiting step 14, and the movable locking end 9 of the anti-theft locking member 7 with the function of preventing external strong magnetic interference can contact and be connected with the limiting step 14 and can form interference fit. Adopt the setting of this embodiment, when the position of activity locking end 9 and spacing step 14 suited mutually, can play the locking effect to lock core 2 promptly, when the position of activity locking end 9 staggers with spacing step 14, have the function of preventing the theftproof locking piece 7 of the strong magnetism interference function in outside promptly and suspend.
Because the utility model relates to an electronic lock tool to lock that has electromagnetic switch 4, consequently electronic lock control assembly include circuit board 15, show operation assembly 16 and power supply unit. The display operation assembly 16 may adopt one or more of a plurality of forms such as a touch digital combination lock, a fingerprint lock, a card lock, etc.
Preferably, the power supply device comprises a battery box device 17 and a USB power supply interface 18, and the battery box device 17 and the USB power supply interface 18 are electrically connected to the circuit board 15 respectively. Typically, the circuit board 15 is powered from a battery in the battery pack assembly 17; in an emergency situation where the battery is out of power, emergency power supply can be performed through the USB power supply interface 18.
In the research and development process, the locking function of the anti-theft locking piece 7 with the function of preventing the external strong magnetic interference can be realized only by additionally installing the simple electronic lock stop piece with the function of preventing the external strong magnetic interference on the basis of the original lock in the initial scheme, but the electronic lock stop piece with the function of preventing the external strong magnetic interference is continuously deformed and reset by the elastic quantity of the material of the electronic lock stop piece in the using process, the condition of incapability of restoring can be generated after multiple times of use, and the anti-theft function is caused to fail. Therefore the utility model provides an improve structure, theftproof locking piece 7 that has promptly and prevent outside strong magnetic interference function is including spacing end 8 of elasticity and activity locking end 9, both ends are all not totally fixed, and all have certain movement allowance, spacing end 8 of elasticity can receive outside magnetic path drive and drive activity locking end 9 and stretch into to keyway 5 in will 2 locks of lock core. More preferably, the elastic limiting end 8 is connected with the lock shell 1 or the switch shell of the electromagnetic switch 4 through an elastic piece. Through the setting of spring 10 for the amount of exercise of elasticity spacing end 8 mainly comes from the variable of spring 10, with the deformation of minimize to have the theftproof locking piece 7 self of preventing the strong magnetic interference function in outside, thereby can be after using for a long time, still have good reliable result of use.
