[0006] As a preferred embodiment of this utility model, the locking mechanism includes a latch piece slidably connected to the outer wall of the lock housing. A latch piece is installed on the outer wall of the latch piece and inside the lock housing. A reversing plate is provided on the outer wall of the latch piece and above the latch piece. A reversing torsion spring is fixedly connected to the outer wall of the lock housing near the reversing plate. A solenoid valve is installed on the outer wall of the lock housing below the latch piece. An actuating gear plate is rotatably connected to the outer wall of the lock housing above the solenoid valve. A lower deflector shaft is installed on the outer wall of the lock housing below the actuating gear plate. A slider is rotatably connected to the outer wall of the lock housing near the slider. A latch plate is rotatably connected to the outer wall of the latch plate. A toggle gear plate is rotatably connected to the outer wall of the latch plate and on the front of the latch plate. A three-latch deflector plate is installed on the outer wall of the latch plate and on the back of the toggle gear plate. An upper deflector shaft is installed on the outer wall of the latch piece near the actuating gear plate.

[0007] As a preferred embodiment of this utility model, the deadbolt extends through and to the outside of the lock housing, and the outer wall of the guide plate has three sets of rectangular through slots on the left side of the locking mechanism.

[0008] As a preferred embodiment of this utility model, the small dial has a T-shaped structure design, and the lock cover is fixedly connected to the lock cover by screws.

[0009] As a preferred embodiment of this utility model, the oblique tongue is composed of an oblique tongue and an oblique tongue rod. The oblique tongue extends through and beyond the guide plate. The outer wall of the guide plate has a square groove at the corresponding position of the oblique tongue, and the square groove is connected to the oblique tongue by a sliding connection.

[0010] As a preferred embodiment of this utility model, the three-bolt lever plate has an arc-shaped structure design and is equipped with rivets. The outer wall of the lever plate has a groove at the corresponding position of the rivet. The actuating gear plate and the starting gear plate are both fan-shaped structures, and the connection between the starting gear plate and the actuating gear plate is an meshing connection.

[0011] Through the above technical solution, the arc-shaped three-bolt pull plate can withstand greater stress and has higher structural strength.

[0012] As a preferred embodiment of this utility model, the oblique tongue extends through and beyond the commutator segment, the commutator segment has an L-shaped structure design, and the outer wall of the lock housing and lock cover has a pivot hole at the corresponding position of the starter gear plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, a single-stage cam slide rail transmission electromagnetic clutch is used to facilitate the locking mechanism in the device to control the opening and closing of the lock body. When locking, the upper shift shaft drives the starting gear plate to rotate. The starting gear plate transmits force to the shift gear plate through the gear teeth on the outer wall. The shift gear plate drives the three bolt shift plates to move together. The rivets on the three bolt shift plates move along the slide rails of the bolt plates, ejecting the main bolt and completing the locking command. When unlocking, the solenoid valve is energized and pushes the slider to rotate along the slots on the outer wall of the lock shell and lock cover. The rotating slider applies force to the clutch plate on the latch lever. The clutch plate closes and drives the upper shift shaft to rotate clockwise. The rotating upper shift shaft drives the latch lever and the starting gear plate to rotate along the slots on the outer wall of the lock shell and lock cover. The drive shaft holes on the lock case and lock cover transmit power and apply force to the drive gear plate and the three-bolt drive plate. During the sliding process of the three-bolt drive plate, the bolt plate rebounds along the bolt plate guide rivets assembled on the lock case and lock cover, completing the unlocking and opening command. This avoids the phenomenon of jamming and jumping when the lock body is engaged or retracted. It is also suitable for scenarios where the door is locked from the outside and the door is opened after the solenoid valve is activated. At the same time, the various moving parts in this structure are generally low-pair structures, with less wear, longer service life and higher reliability. They are also easy to process and can achieve high geometric precision. This solves the problem that existing lock bodies will jam and jump when engaged or retracted, resulting in the lock body not being able to retract or engage properly, greater wear, and shorter service life.

An actuating gear plate 206 is rotatably connected to the outer wall of the lock housing 1 above the solenoid valve 205. A lower derailleur 207 is installed. A slider 208 is rotatably connected to the outer wall of the lock housing 1 below the starter gear plate 206. A bolt plate 209 is provided on the outer wall of the lock housing 1 near the slider 208. A slanted tongue starter plate 210 is rotatably connected to the outer wall of the bolt plate 209. A toggle gear plate 211 is rotatably connected to the outer wall of the bolt plate 209 and the front of the slanted tongue starter plate 210. A three-bolt derailleur 212 is installed on the outer wall of the bolt plate 209 and the back of the toggle gear plate 211. An upper derailleur 213 is installed on the outer wall of the slanted tongue derailleur 202 near the starter gear plate 206.

[0022] The oblique tongue 201 consists of an oblique tongue and an oblique tongue rod. The oblique tongue 201 penetrates and extends to the outside of the guide plate 3. The outer wall of the guide plate 3 has a square groove at the corresponding position of the oblique tongue 201, and the square groove is connected to the oblique tongue 201 by sliding connection.

[0023] The three-bolt lever plate 212 has an arc-shaped structure and is equipped with rivets. The outer wall of the lever plate 209 has a groove at the corresponding position of the rivet. The arc-shaped three-bolt lever plate 212 can withstand greater stress and has high structural strength. The actuating gear plate 211 and the starting gear plate 206 are both fan-shaped structures.

[0025] The working process of this utility model is as follows: When the first-gear cam slide groove transmission electromagnetic clutch lock body designed in this scheme is in use, when locked, the upper push shaft 213 drives the start gear plate 206 to rotate. The start gear plate 206 transmits force to the push gear plate 211 through the gear teeth on the outer wall. The push gear plate 211 drives the three bolt push plate 212 to move together. The rivets on the three bolt push plate 212 move along the slide groove in the bolt plate 209 to pop out the main bolt and complete the door closing and locking command. When unlocking, the solenoid valve 205 is energized and pushes the slider 208 to rotate along the slots opened on the outer walls of the lock housing 1 and the lock cover 4. The rotating slider 208 applies force to the clutch plate on the tongue 202. The clutch plate closes and drives the upper lever shaft 213 to rotate clockwise. The rotating upper lever shaft 213 drives the tongue 202 and the starting gear plate 206 to rotate along the lever holes opened on the lock housing 1 and the lock cover 4, and applies force to the lever plate 211 and the three-bolt lever plate 212. During the sliding process of the three-bolt lever plate 212, the bolt plate 209 rebounds along the bolt plate guide rivets combined on the lock housing 1 and the lock cover 4, thus completing the unlocking and opening command. When the handle retracts to open the door, the lower lever shaft 207 or the upper lever shaft 213 rotates clockwise and drives the latch lever 202 to perform lever arm transmission. The latch lever 202 rotates clockwise around the middle lever shaft. After rotation, the latch lever 202 drives the latch piece 201 to move in a straight line along the lock housing 1 and the lock cover 4, so that the latch piece 201 retracts and completes the door opening transmission process. When the lock cylinder key closes and locks the door, the lock cylinder key rotates along the lock cylinder gourd hole on the lock housing 1 and the lock cover 4, and moves to the lever point with the three-bolt lever plate 212. The lock cylinder key moves the three-bolt lever plate 212, and the three-bolt lever plate 212 pushes the three-bolt plate slide groove for transmission. The bolt plate 209 pops out along the bolt plate guide rivet combined on the lock housing 1 and the lock cover 4, completing the transmission process of closing and locking the door. When the lock cylinder key is used to open and unlock the door, the lock cylinder key rotates in the opposite direction along the lock cylinder gourd hole on the lock shell 1 and the lock cover 4, and moves in the opposite direction to the lever point of the latch start plate 210 and the three bolt lever plate 212, which drives the bolt plate 209 and the latch piece 201 to retract. The three bolt lever plate 212 moves in the opposite direction along the three bolt plate slide groove. The latch start plate 210 uses the lever arm to move the latch lever 202 and the latch piece 201, completing the transmission process of opening and unlocking the door.
