[0005] Technical solution: The utility model is a new type of isolation lock device, which is characterized by: including a lock box, a lock box cover, a dial plate on the side of the lock box, and a lock core on the surface of the lock box cover; the lock box cover is provided with a flange 1, a nut, a large gear and a gasket connected in sequence, the large gear is connected to the small gear, the small gear is connected to the flange 2, and the small gear is connected to the shaft and the mounting plate in sequence; the lock box is connected to the dial ring through a torsion spring.

[0006] Wherein, the large gear and the small gear are meshed and connected via corresponding gears.

[0007] Wherein, the shaft sleeve is fitted inside the pinion gear.

[0008] Wherein, the shaft is connected with the dial plate.

[0009] Wherein, one end of the torsion spring is fixed on the lock box, and the other end is fixed on the dial ring.

[0010] Wherein, the lock box is located on the door of the urban rail transit vehicle.

[0011] Beneficial effects: Compared with the prior art, the utility model has the following significant advantages: the utility model adopts a new isolation transmission structure, occupies a small space, solves the problem that the existing device occupies a large space, and overcomes the usage limitations of the existing device.

Specific embodiments

[0020] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] The novel isolation lock device of the present utility model includes a lock box 14. The lock box 14 is provided with a lock box cover 1. A dial plate 3 is provided on the side of the lock box 14. A lock core 2 is provided on the surface of the lock box cover 1. Inside the lock box cover 1, there are flange one 4, nut 5, large gear 6 and washer 7 connected in sequence. The large gear 6 is connected to the small gear 10. The small gear 10 is connected to flange two 9. The small gear 10 is connected to the shaft 13 and the mounting plate 12 in sequence. The lock box 14 is connected to the dial ring 11 through a torsion spring 8. Among them, the large gear 6 and the small gear 10 are connected by corresponding gears in mesh. The shaft 13 is sleeved inside the small gear 10. The shaft 13 is connected to the dial plate 3. One end of the torsion spring 8 is fixed on the lock box 14, and the other end is fixed on the dial ring 11. The lock box 14 is located on the door of an urban rail transit vehicle.

[0022] When in use, rotate the lock core 2 clockwise. The lock core 2 drives the large gear 6 to rotate. The large gear 6 meshes with the small gear 10, and the small gear 10 rotates clockwise. The shaft 13 is sleeved inside the small gear 10, so that the shaft 13 rotates clockwise. The dial 3 is connected to the shaft 13, and the dial 3 rotates, thereby triggering an external switch and outputting an isolation signal. One end of the torsion spring 3 is fixed on the lock box 14, and the other end is fixed on the dial ring 11. Under the action of the self-resetting force of the torsion spring 8, the dial 3 returns to the initial state position.
