Description

Technical Field

[0001] This utility model belongs to the field of locomotive electrical technology, specifically relating to a quick-action switch pressing structure. Background Technology

[0002] Quick-action switches are important and commonly used components in electrical products such as driver controllers and brake controllers in trains and subway vehicles. Their main function is to achieve the opening and closing of the quick-action switch by pressing it, thereby achieving the purpose of connecting and disconnecting electrical signals. The traditional pressing method is to design a cam or ratchet structure, which is complex, has high manufacturing cost, occupies a lot of space, and has poor overall efficiency.

[0010] (III) Technical Effects

[0011] When the quick-action switch pressing structure provided by this utility model is working, the lock cylinder of the rotating lock body drives the rotating disk connected to it. When the rotating disk rotates, it presses the spring of the quick-action switch through a specific fork structure, thereby realizing the closing and opening of the quick-action switch, and thus meeting the needs of connecting and cutting off electrical signals. The anti-loosening structure of ratchet nut and positioning pin has good anti-loosening effect and high reliability. The quick-action switch pressing structure has a simple structure, high efficiency and reliability, low manufacturing cost, and can realize the synchronous adjustment of multiple quick-action switches at the same time.

Figure 2 The side view of the quick-action switch pressing structure that synchronously adjusts three quick-action switches provided in this embodiment is shown in the figure. The quick-action switch pressing structure includes a lock body 1 and a rotating disk 3. A positioning pin 2 and a ratchet nut fix the rotating disk 3 and the lock body 1 together. A fork structure is provided on the rotating disk 3. When the lock cylinder of the lock body 1 is rotated, the rotating disk 3, which is connected to the lock body 1, is driven to rotate. When the rotating disk 3 rotates, it drives the fork structure to press the spring on the quick-action switch 4, thereby realizing the closing and opening of the quick-action switch 4 and meeting the needs of connecting and cutting off electrical signals.

[0020] The thickness of the shift fork structure can be adjusted and designed as needed, so that the shift fork structure can press the springs on multiple quick-action switches at the same time, and realize the synchronous adjustment of multiple quick-action switches. At this time, the number of quick-action switches is ≥1, and the thickness of the shift fork structure is not less than the sum of the widths of the springs of multiple quick-action switches.

[0021] When the quick-action switch pressing structure provided by this utility model is working, the lock cylinder of the rotating lock body drives the rotating disk connected to it. When the rotating disk rotates, it presses the spring of the quick-action switch through a specific fork structure, thereby realizing the closing and opening of the quick-action switch, and thus meeting the needs of connecting and cutting off electrical signals.
