[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] By setting up a pressing component, when the movable frame is pressed, pressure is applied to both swing rods simultaneously. This allows the force to be transmitted synchronously to the two semi-circular protrusions, causing them to rotate. This causes the two sliding seats to slide in a direction away from each other, increasing the distance between the two slots. This allows the circuit breaker's trip lever to be operated by the crank handle, and one hand can press the movable frame while the other hand operates the crank handle, thus achieving single-person operation.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1-4 As shown, an electric chassis vehicle door locking structure includes a mounting plate 4, a pressing member 2, a left locking member, and a right locking member. The left and right locking members have the same structure. The left locking member includes a fixed base 11, a sliding base 13, and a first spring 12. The fixed base 11 is fixed to the mounting plate 4 by bolts, and a groove 17 is provided at the bottom of the fixed base 11. The sliding base 13 is slidably disposed on the mounting plate 4. The first spring 12 is located in the groove 17, and both ends of the first spring 12 abut against the fixed base 11 and the sliding base 13, respectively. The fixed base 11 rotates upwards... A semi-circular protrusion 15 is provided on the sliding seat 13, and a pressing groove 16 is provided on the sliding seat 13. The vertical surface of the lower half of the semi-circular protrusion 15 abuts against the side of the pressing groove 16. A limiting member 14 for controlling the sliding distance of the sliding seat 13 is provided on the mounting plate 4. A swing rod 10 is rotatably provided on the fixed seat 11. The middle part of the swing rod 10 abuts against the upper end of the semi-circular protrusion 15. The two sliding seats 13 are provided with semi-circular opening grooves 18 at their close ends. A pressing member 2 is provided on the mounting plate 4, and one end of the two swing rods 10 abuts against the pressing member 2.

[0017] The pressing component 2 includes a movable frame 7, a limiting bolt 6, and a second spring 5. There are two of each of the limiting bolt 6 and the second spring 5. One end of the limiting bolt 6 passes through the movable frame 7 and is fixedly connected to the mounting plate 4. The second spring 5 is sleeved on the outside of the limiting bolt 6 and applies a force to the movable frame 7 away from the mounting plate 4. The center of the movable frame 7 is provided with a clearance hole 8 for the crank handle 3 to pass through. One end of the swing rod 10 is rotatably provided with a roller 9, which abuts against the movable frame 7.

[0018] The limiting component 14 includes a movable column 22 and a third spring 21. The movable column 22 is slidably mounted on the mounting plate 4, and the sliding direction of the movable column 22 is perpendicular to the sliding direction of the sliding seat 13. The bottom of the sliding seat 13 is provided with a limiting groove 19. One end of the movable column 22 is provided with a protrusion 20. The third spring 21 is sleeved on the movable column 22, and the third spring 21 applies a force to the movable column 22 to resist the sliding seat 13, and allows a part of the protrusion 20 to be embedded in the limiting groove 19.

[0019] Working principle: When the crank handle 3 is needed to operate the circuit breaker's trip lever 1, pressing the movable frame 7 compresses the second spring 5, causing the movable frame 7 to push the swing rod 10 downwards to rotate. This causes the swing rod 10 to rotate the semi-circular protrusion 15, which in turn generates a pushing force on the sliding seat 13 towards the fixed seat 11. This increases the distance between the slots 18 on the two sliding seats 13, allowing the crank handle 3 to be smoothly inserted between the two sliding seats 13 onto the circuit breaker's trip lever 1, thus achieving the tripping operation.
