Further, a joint is arranged on the swing arm, and the main lock rod is connected with the swing arms of the locking machine and the unlocking machine through the joint on the swing arm.
Further, a connecting groove is arranged on the main lock rod, and the inner unlocking rod of the inner unlocking handle is slidably connected in the connecting groove of the main lock rod.
Further, a restraint sleeve is sleeved on the main lock rod and is fixed in the emergency door through a connecting bracket.
Further, the inner opening handle is provided with a sliding cover, and the sliding cover is provided with an alarm switch for opening induction.
Further, the locking machine and the unlocking machine are provided with micro switches for unlocking and alarming.
The invention has the advantages that the clamping plate type locking machine with the two-gear locking function is adopted, the unexpected opening of the door lock in the running process of the vehicle can be prevented, and the safety is high. Simultaneously, the door lock is provided with the inner opening handle and the outer opening handle, and the door lock can be opened outside the vehicle, so that the use is convenient. The inner unlocking rod of the inner unlocking handle is slidably connected to the main locking rod, the outer unlocking rod of the outer clamping handle is slidably connected to the swing arm of the lower locking machine, and the inner unlocking and the outer unlocking do not interfere with each other. The swing arm is provided with two arc-shaped grooves at different positions, so that the swing arm can be suitable for outward opening handles of different shapes and forms, and a locking machine is not required to be replaced when the outward clamping handle structure is replaced.

Detailed Description
The invention is described in detail below with reference to the attached drawings and detailed description:
as shown in fig. 1 to 3, the embodiment of the invention comprises a locking machine 2 and a locking machine 3, wherein the locking machine 2 and the locking machine 3 are both clamping plate type locking machines, the locking machine comprises a fan-shaped swing arm 8, an arc-shaped groove 8-1 is arranged on the swing arm 8, and an outer unlocking rod 4-1 of an outer unlocking handle 4 is slidably connected in the arc-shaped groove 8-1. The swing arm 8 is provided with a joint 8-2, and the main lock rod 5 is connected with the swing arms 8 of the locking machine 2 and the locking machine 3 through the joint 8-2 on the swing arm 8. The joint 8-2 can rotate relative to the swing arm 8, the main lock rod 5 moves up and down, and the swing arm 8 can be pulled, so that the internal driving piece is driven to rotate, the clamping plate 10 is driven to be opened, and unlocking is completed.
The main lock rod 5 is provided with a connecting groove 5-1, and the inner unlocking rod 1-1 of the inner unlocking handle 1 is slidably connected in the connecting groove 5-1 of the main lock rod 5. The inner unlocking rod 1-1 and the outer unlocking rod 4-1 are respectively connected with the main locking rod 5 and the lower locking machine 3 in a sliding way, so that the main locking rod 5 does not drive the inner unlocking rod 1-1 or the outer unlocking rod 4-1 to generate unnecessary movement when moving up and down.
The main lock rod 5 is sleeved with a restraint sleeve 7, and the restraint sleeve 7 is fixed on the emergency door through a connecting bracket 6. The restraining sleeve 7 can prevent abnormal sound caused by large shaking amount of the main lock rod 5 during up-and-down movement.
The two arc-shaped grooves 8-1 on the swing arm 8 are respectively arranged at the two ends of the swing arm 8, so that the swing arm 8 can be suitable for the outward opening handles 4 with different shapes, and the locking machine is not required to be replaced when the structure of the outward clamping handle 4 is replaced.
The inner opening handle 1 is provided with a sliding cover, and the sliding cover 1 is provided with an alarm switch for opening induction. The locking machine 2 and the unlocking machine 3 are provided with a micro switch 9 for unlocking and alarming. When the door lock is opened due to bumping of the vehicle, an alarm can be sent out timely, and the safety can be improved by the aid of the two-layer alarm mechanism. The locking machine 2 and the locking machine 3 are both clamping plate type locking machines, have two-gear locking functions, and improve safety.
Fig. 4 is a schematic diagram of a connection structure between a locking mechanism 3 and an external door lock 4 in the second embodiment of the present invention, wherein the shape of the external handle lock 4 is different from that of the first embodiment, and the arc-shaped slot 8-1 connected with the external locking lever 4-1 is also different from that of the first embodiment, so that the two arc-shaped slots 8-1 can be applied to external handles 4 with different shapes, and the locking mechanism is not required to be replaced when the structure of the external handle lock 4 is replaced.
