Description

Technical Field

[0001] The utility model relates to the field of isolating switches, in particular to a novel isolating switch component. Background Art

[0002] Traditional isolating switches used in rail transit vehicle doors consist of a switch box, cam, torsion spring, mounting plate, switch box cover, and microswitch. Existing isolating lock switch assemblies occupy a large amount of mounting space on the vertical cover plate along the length of the vehicle and are relatively expensive. Reed-type isolating lock switches are prone to accidental triggering of the lock tongue, resulting in low reliability.

[0003] Therefore, it is necessary to develop new types of isolating switch components in a targeted manner to reduce installation space and reduce costs. Utility Model Content

[0004] Purpose of the utility model: In view of the shortcomings and defects of the existing technology, the utility model provides a new type of isolating switch assembly, which occupies a small space in the vehicle width direction and requires little space for the side cover plate of the vehicle body; it has a simple structure and low cost.

[0005] Technical solution: The utility model is a new type of isolating switch assembly, which is characterized by comprising a lock box, a switch provided in the lock box, the switch, the trigger block and the push rod being connected in sequence; and a compression spring being wound around the outside of the push rod.

[0006] Wherein, the switch comprises two upper and lower switch parts.

[0007] Wherein, the lock box is provided with a lock core and a lock tongue, and the lock tongue is connected to the push rod.

[0008] Wherein, the lock box is provided with a mounting seat, and the lock box is connected to the external mechanism via the mounting seat.

[0009] Wherein, a limiting fixing point for limiting the push rod is provided in the middle of the lock box.

[0010] Beneficial Effects: Compared with existing technologies, this utility model has the following significant advantages: The isolating switch assembly occupies less space across the vehicle width, requiring less space for the vehicle's side vertical cover panels. The isolating switch assembly utilizes a novel triggering method, with the inclined surfaces on both sides of the trigger block triggering the two switches, improving device reliability and reducing operational failure rates. The isolating switch assembly is simple in structure and low in cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0017] The novel isolating switch assembly of the present utility model comprises a lock box 1, which houses a switch 2. The switch 2, a trigger block 3, and a push rod 5 are sequentially connected. A compression spring 4 is wrapped around the outside of the push rod 5. The switch 2 comprises upper and lower switch sections. The lock box 1 is equipped with a lock cylinder and a lock tongue, which are connected to the push rod 5. The lock box 1 is provided with a mounting base, which connects the lock box 1 to an external mechanism. A limit fixing point is provided in the center of the lock box 1 for limiting the position of the push rod 5.

[0018] During use, the external isolation lock cylinder is rotated with a specific square key. The lock tongue of the isolation lock extends, pushing the push rod, which moves rightward, pushing the trigger block to the right. The trigger block triggers the upper and lower switches, causing the isolation switch assembly to send a signal to unlock. When the lock tongue retracts, the isolation switch assembly resets itself via the compression spring. At the same time, the intermediate fixing point between the mounting base and the lock box prevents excessive movement of the push rod, acting as a limiter.
