Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a push-button switch with a protective structure. Background Technology

[0002] A locking switch is a safety device used to prevent misoperation or accidents. Its applications include controlling the operating sequence of equipment, preventing dangerous operations, and protecting personnel safety. It is widely used in high-risk environments such as underground coal mines, high-voltage switchgear, chemical plants, and nuclear power plants to ensure the safe and stable operation of systems.

[0003] Conventional normally closed switches remain energized and conductive during initial installation, assembly, and removal from equipment, requiring manual pressing to disconnect. This design presents a significant safety flaw: when the switch is removed from the equipment, it remains energized, posing a high risk of electric shock to operators should energize the equipment during maintenance if power is accidentally restored. Furthermore, industrial sites often require non-shutdown maintenance of live equipment. With traditional switches, disconnecting the power requires another person to press the switch for an extended period, which is impractical in confined spaces, forcing technicians to work in a continuously energized, high-risk environment. This risk of misoperation is further amplified in multi-person collaboration or complex operating conditions, making it difficult for existing switch structures to meet inherent safety requirements. Addressing this industry pain point, a new switch structure is urgently needed that automatically disconnects the circuit during disassembly and forcibly isolates the power supply during maintenance, fundamentally eliminating electrical safety hazards during equipment maintenance. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the traditional switch design and provide a product that ensures safe maintenance.

[0005] A push-button switch with a protective structure includes: a moving contact; a moving spring disposed at the upper and lower ends of the moving contact; a stationary spring disposed on one side of the moving contact, the stationary spring being disposed on the moving trajectory of the moving spring; a flexible connecting wire provided between the two moving springs; a first elastic element provided between the two moving springs, causing the moving spring and the stationary spring to abut against each other, for putting the circuit in a conductive state; and a second elastic element, which applies an upward force to the moving contact, causing one of the moving springs to move away from one of the stationary springs, for cutting off the conductive state in the initial state.

[0006] Preferably, it also includes a base, the base having a slide groove for raising and lowering the movable contact frame, the upper and lower ends of one side of the slide groove having limiting portions for restricting the range of motion of the movable spring, and the second elastic element being disposed at the bottom of the slide groove.

[0007] Preferably, the movable spring is provided with a movable contact, and the back of the movable spring is provided with an anti-detachment plate, the anti-detachment plate being provided with a groove for accommodating the first elastic element.

[0008] Preferably, the movable spring has a bent conductive part, which is arranged in an up-down opposite manner, and the flexible connecting wire is electrically connected to the conductive part by welding.

[0009] Preferably, the stationary spring has a stationary contact corresponding to the moving contact, and the stationary spring is fixed to the base.

[0010] Preferably, the movable contact frame is provided with a guide groove for the movable spring to rise and fall, and the movable contact frame is provided with a pressing part that protrudes from the base.

[0011] Preferably, the first elastic element and the second elastic element are configured as springs. Beneficial effects

Through the structural design of the second elastic element 6 and the first elastic element 5, the interlocking switch is ensured to remain stably disconnected throughout the entire process of initialization, assembly and disengagement from the equipment. This feature not only provides a solid safety barrier for equipment maintenance operations and effectively protects the personal safety of personnel, but also enables flexible operation in small and complex maintenance spaces. This design significantly improves the convenience and efficiency of maintenance operations. At the same time, its inherent safety protection mechanism further strengthens the safety of the entire maintenance process. It is worth mentioning that it also includes a base 7, which is provided with a slide groove 71 for the moving contact frame 1 to rise and fall. The upper and lower ends of one side of the slide groove 71 are provided with limiting parts 72 for limiting the range of motion of the moving spring 2. The second elastic member 6 is provided at the bottom of the slide groove 71. It is worth mentioning that the moving spring 2 is provided with a moving contact 21, and the back of the moving spring 2 is provided with an anti-detachment plate 22. The anti-detachment plate 22 is provided with a groove 23 for accommodating the first elastic member 5.

Applying downward pressure to the pressing part 12 causes the movable contact frame 1 to fall down and counteract the force of the second elastic member 6. The first elastic member 5 releases elastic force to the movable spring 2, so that the movable contact 21 abuts against the stationary contact 31 to achieve the conducting state. When no force is applied to the pressing part 12, it is in the non-conducting state. It is worth mentioning that the first elastic element 5 and the second elastic element 6 are set as springs.
