[0020] As Figures 1 to 4As shown, the gate locking mechanism provided by the embodiment comprises a rack 1 and a motor 2 fixedly installed on the rack 1, the motor 2 is connected with a reduction box 3, an output shaft of the reduction box 3 is connected with a gate lever of a gate machine, the output shaft of the reduction box 3 is also fixedly connected with a locking disc 4, edges of the locking disc 4 are provided with protruding teeth 5, the protruding teeth 5 and the protruding teeth 5 form tooth grooves 6 therebetween, one side of the rack 1 close to the locking disc 4 is provided with an electromagnet 7 and a first locking rod 8 and a second locking rod 9 rotatable through a shaft rod, the electromagnet 7 is a bidirectional electromagnet, an armature 10 at one end of the electromagnet 7 is in through connection with the first locking rod 8, an armature 10 at the other end of the electromagnet 7 is in through connection with the second locking rod 9, the armature 10 of the electromagnet 7 is all sleeved with corresponding springs 11, the springs 11 on different armatures are respectively in abutment with the first locking rod 8 and the second locking rod 9, the armature 10 of the electromagnet 7 is provided with a convex ring 17 at the other end face relative to the first locking rod 8, the end of the armature 10 of the electromagnet 7 is provided with a nut head 18 at the connection position of the second locking rod 9, under the action of the spring 11, one end of the first locking rod 8 abuts on the convex ring 17, one end of the second locking rod 9 abuts on the nut head 18, the other end of the first locking rod 8 and the second locking rod 9 is provided with a locking column 12 which can be embedded into the tooth groove 6.

[0021] Wherein, when the locking disc 4 moves, whenever the tooth groove 6 on the locking disc 4 is opposite to the locking column 12 on the first locking rod 8, the locking column 12 on the second locking rod 9 is opposite to the protruding tooth 5 on the locking disc 4, whenever the protruding tooth 5 on the locking disc 4 is opposite to the locking column 12 on the first locking rod 8, the locking column 12 on the second locking rod 9 is opposite to the tooth groove 6 on the locking disc 4.

[0022] The embodiment mainly adopts a single electromagnet 7 with bidirectional movement to connect the first locking rod 8 and the second locking rod 9, so as to realize that the locking columns 12 of the first locking rod 8 and the second locking rod 9 are synchronously close to the locking disc 4, meanwhile, the first locking rod 8 and the second locking rod 9 are staggered arranged relative to the protruding tooth 5 and the tooth groove 6, so that when locking, one of the locking columns 12 can be quickly inserted into the tooth groove 6 to complete the quick locking of the gate.

[0023] In specific application, when the gate system sends a locking instruction, the electromagnet 7 works, for example, Figure 1As shown, the armature 10 is moved to the right, and both ends are moved to the right, so that after moving, the first locking rod 8 and the second locking rod 9 are simultaneously rotated, so that the locking column 12 at the other end of the first locking rod 8 and the second locking rod 9 is moved towards the locking disc 4, wherein when the locking column of the first locking rod 8 is inserted into the tooth groove 6, the locking disc 4 is clamped and moved, thereby achieving the purpose of locking, and the locking column 12 of the second locking rod 9 is in contact with the convex tooth 5, and even if it cannot be inserted into the tooth groove 6, it will rely on the spring 11 to play a buffering role, wherein the hole of the first locking rod 8 and the second locking rod 9 and the armature 10 is oval or has a diameter larger than that of the armature 10, so that it can be adapted to rotate. At the same time, when the locking column 12 of the second locking rod 9 is inserted into the tooth groove 6, the principle is the same as described above, so it is not repeated. When the locking state needs to be released, the armature 10 of the electromagnet 7 is controlled to move to the left, and under the driving of the convex ring 17 and the nut head 18, the first locking rod 8 and the second locking rod 9 move to the left, and the other end of the first locking rod 8 and the second locking rod 9 is naturally away from the locking disc 4, so that the locking state is released.

[0024] Further, in order to ensure that the spring 11 can stably abut against the first locking rod 8 and the second locking rod 9, a gasket 13 is arranged at the abutting position of the first locking rod 8 and the second locking rod 9 of the embodiment, and under the action of the spring 11, the gasket 13 abuts against the first locking rod 8 and the second locking rod 9, respectively.

[0025] Further, in order to better feed back the rotation angle of the locking disc 4, that is, the rotation direction of the brake rod to the gate system, at least one photoelectric switch 14 is arranged below the locking disc 4 of the rack 1 of the embodiment, and at least one trigger block 15 is arranged on the lower end surface of the locking disc 4 and can cooperate with the photoelectric switch 14.

[0026] Further, in order to avoid foreign matters from falling into the tooth groove 6 of the locking disc 4, an outer cover 16 is arranged on the locking disc 4 of the rack 1 of the embodiment, and the outer cover 16 is provided with a avoiding hole at the first locking rod 8 and the second locking rod 9, so that the outer cover 16 can cut off the locking disc 4 from the outside and prevent foreign matters from entering the inside.
