Specifically, the electromagnetic lock with the electric frequency conversion realizes the locking function of the door through the triangular bolt part 2. The triangular plug head 22 is extended out of the communication hole 121 when the triangular plug is normally at rest, and the sliding rod 23 is pushed by the torsion spring 231 against the transverse part of the L-shaped baffle plate 14 to keep the triangular plug body 21 and the triangular plug head 22 in the state. When the door needs to be locked, the electromagnet 32 is powered on, the adsorption end 312 of the rotating support rod 31 is adsorbed on the electromagnet 32, the rotating support rod 31 rotates around the bearing column, the clamping end 311 tilts up, the clamping end 311 blocks the sliding opening 16, when the door is opened, the door frame extrudes the triangular bolt head 22 to push the triangular bolt head into the lock shell 11, the triangular bolt body 21 slides in the sliding groove 15, one end of the sliding rod 23 slides towards the sliding opening 16 on the transverse part of the L-shaped baffle plate 14 through the first rolling shaft 232, but the sliding rod 23 cannot slide towards the sliding opening 16 due to the blocking of the sliding rod 23 by the clamping end 311, so that the sliding rod 23 abuts against the triangular bolt body 21 and the triangular bolt head 22, the triangular bolt head 22 cannot retract into the lock shell 11 and is continuously matched with the door frame, and the purpose of locking the door is achieved. When the door needs to be opened, the electromagnet 32 is powered off and the adsorption end 312 is loosened, the clamping end 311 falls down and does not block the sliding opening 16 any more, when the door frame extrudes the triangular bolt head 22, the sliding rod 23 can smoothly slide to the sliding opening 16 to the side edge, and the triangular bolt head 22 retracts into the lock shell 11, so that the door is opened. When the circuit is powered off accidentally, the electromagnet 32 loses magnetic force and cannot adsorb the adsorption end 312, so that the electric variable frequency electromagnetic lock can keep a smooth unlocking state under the condition of power failure. After the door is opened or closed, the sliding rod 23 is reset by the elastic potential energy stored in the torsion spring 231, and the triangular bolt body 21 drives the triangular bolt head 22 to extend out of the communication hole 121.
As a further preferred embodiment, the triangular bolt head 22 includes a first bolt head 22a and a second bolt head 22b which have the same shape but are oppositely arranged, the triangular bolt head 22 has a straight surface 221 and an inclined surface 222, and the first bolt head 22a and the second bolt head 22b are both arranged with the straight surface 221 facing outwards and the inclined surface 222 facing inwards.
Specifically, the bolt head I22 a and the bolt head II 22b which are identical in shape but are oppositely arranged can enable the electric frequency conversion electromagnetic lock of the machine to be used in both directions without distinguishing the door opening direction and the door closing direction, when one triangular bolt head 22 contacts a door frame, the door frame firstly extrudes a straight surface 221 of the door frame and enables the door frame to rotate inwards, the door frame then contacts an inclined surface 222 of the other triangular bolt head 22, and because the straight surface 221 of the second triangular bolt head 22 is matched with the panel 12 to enable the door frame not to rotate outwards, the door frame is matched with the inclined surface 222 of the second triangular bolt head 22, so that the whole triangular bolt part 2 retracts into the lock shell 11, and the door opening or closing operation is realized.
As a further preferred embodiment, the rotational connection of the triangular bolt head 22 is provided with a semicircular projection 223.
Specifically, when the cam bolt head 22 contacts and rotates with the door frame, the side edge of the semicircular projection 223 contacts with the inner side of the outer connection surface 111, and the cam bolt head 22 retracts into the lock case through the lever principle, thereby facilitating the door opening and closing operation.
As a further preferred embodiment, a reset hole 313 is arranged in the middle of the rotating support rod 31 near the clamping end 311, a rivet column 314 is arranged on the inner wall of the lock housing 11 corresponding to the reset hole 313, a reset spring 315 is arranged on the rivet column 314, the rivet column 314 extends into the reset hole 313, and the reset spring 315 is connected with the reset hole 313.
Specifically, when the electromagnet 32 loses the magnetic force, the suction end 312 needs to be lifted, and the engaging end 311 needs to fall, so that the engaging end 311 does not block the sliding opening 16. When the electromagnet 32 adsorbs the adsorption end 312, the reset spring 315 is stretched to store elastic potential energy, when the electromagnet 32 loosens the adsorption end, the elastic potential energy of the reset spring 315 is released to pull down the clamping end 311, so that the reset of the rotating support rod 31 is completed, and after the reset, the reset spring 315 is located in the reset hole 313, so that excessive space cannot be occupied, the riveting column 314 can ensure that the stretched shape of the reset spring 315 keeps a straight line, and the reset spring 315 can be smoothly contracted into the reset hole 313.
As a further preferred embodiment, a third roller 316 is provided on the locking end 312.
Specifically, when the local electrical variable frequency electromagnetic lock is in an unlocked state, the sliding rod 23 can slide out of the sliding port 16, but the torsion spring 231 exerts pressure on the sliding rod 23, so that the sliding rod 23 and the first rolling shaft 232 are tightly pressed on the transverse part of the L-shaped baffle 14, when the sliding rod 23 slides out of the sliding port 16, the first rolling shaft 232 may be clamped between the transverse part of the L-shaped baffle 14 and the clamping end 311, which causes a failure in smooth unlocking and a mechanical failure, and the third rolling shaft 316 can roll when the first rolling shaft 232 is in contact, so that the sliding rod 23 slides smoothly, thereby ensuring the smooth operation of the local electrical variable frequency electromagnetic lock; when the sliding rod 23 is reset, the third roller 316 can also be reset smoothly, so as to ensure that the cam bolt head 22 is not blocked in the lock case 11, which results in the door being unable to be closed.
What has been described herein is merely a preferred embodiment of the invention, and the scope of the invention is not limited thereto. Modifications, additions, or substitutions by those skilled in the art to the specific embodiments described herein are intended to be within the scope of the invention.
