Description

Technical Field

[0001] This utility model relates to the field of electrical switch locking technology, and in particular to an electrical switch locking device to prevent misoperation. Background Technology

[0002] Electrical switches are electrical components or equipment that are prone to wear and tear and malfunction. Electrical switch locking devices are devices that prevent electrical switches from being operated accidentally or without authorization by means of mechanical, electromagnetic or electronic codes. They are composed of different components such as lock body, lock cylinder, electromagnetic coil, and electronic control unit, and are widely used in many fields such as industry, power, construction, and transportation to ensure the safe and stable operation of electrical equipment and the safety of personnel.

[0003] However, existing electrical switch locking devices usually have a fixed structure. Since there are many types of electrical switches, their locking positions also vary, making it difficult for the locking devices to be adapted to various types of electrical switches, which is inconvenient to use. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose an electrical switch locking device to prevent misoperation, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides an electrical switch locking device to prevent misoperation, comprising an electrical switch as the protective body, a switch operating component for opening and closing control at one end of the electrical switch, a locking hole for locking the switch operating component inside the switch operating component, a locking fixing seat for mounting and fixing the electrical switch on one side of the locking hole, a movable seat for position adjustment inside the locking fixing seat, a locking block for reciprocating movement fixedly installed inside the movable seat, a locking rod for locking with the locking hole fixedly installed at one end of the locking block, and an adjustment component for driving and controlling the locking rod fixedly installed at one end of the locking rod.

[0006] Preferably, in any of the above embodiments, the electrical switch has an internal control circuit for electrical connection, the switch operating component is connected to the control circuit, the locking hole is located on one side of the switch operating component, and one end of the electrical switch has a fixing groove located on one side of the locking hole for fixing the locking fixing seat.

[0007] The above technical solution is adopted as follows: the control circuit inside the electrical switch is responsible for the electrical connection, and the switch operating component is connected to it to realize the opening and closing control of the electrical switch. The locking hole is opened on one side of the switch operating component to provide a locking position for the locking rod. The fixing groove at one end of the electrical switch is used to install the locking fixing seat, so that the locking device is tightly connected with the electrical switch to ensure the reliability of the locking function.

[0008] Preferably, in any of the above embodiments, the locking fixing base includes a locking housing for support and limiting and a locking end cap for disassembly and assembly protection. The locking housing is fixedly installed inside the electrical switch, and the locking end cap is snapped onto one end of the locking housing.

[0009] The above technical solution is adopted: the locking housing of the locking fixing seat is fixed inside the electrical switch, providing stable support and limiting space for components such as the movable seat and locking block. The locking end cover is snapped onto one end of the locking housing, which is convenient for disassembly and assembly. During installation and maintenance, the locking end cover can be opened to inspect and replace the internal components. After installation, it can also protect the internal components and prevent dust and debris from entering and affecting the normal operation of the locking device.

[0010] Preferably, the movable seat includes an adjusting seat that moves inside the locking housing, a high-strength spring that provides power, and a positioning tooth plate for positioning and engagement. The adjusting seat is located inside the locking housing, and high-strength springs are fixedly installed at both ends of the adjusting seat. A positioning tooth plate that moves inside the adjusting seat is fixedly installed at one end of the high-strength spring.

[0011] The above technical solution is adopted: the adjusting seat of the movable seat can move flexibly inside the locking housing, and the high-strength springs at both ends provide elastic force for the adjusting seat, allowing it to move within a certain range. The positioning tooth plate moves inside the adjusting seat and cooperates with the tooth groove on the locking housing. When the adjusting seat moves to the appropriate position, the positioning tooth plate is engaged with the tooth groove to fix the adjusting seat, ensuring that the locking rod can be accurately positioned to the locking hole position of different electrical switches, thus improving adaptability.

[0012] Preferably, in any of the above embodiments, the locking block includes a locking support whose moving direction is perpendicular to the moving direction of the adjusting seat, a locking spring that provides power, and a locking block that engages. The locking support is movably connected to the interior of the adjusting seat, a locking spring is fixedly installed at one end of the locking support, and a locking block that moves inside the locking support is fixedly installed at one end of the locking spring.

[0013] The above technical solution is adopted: the locking support of the locking block moves inside the adjusting seat and the direction of movement is perpendicular to the adjusting seat, which expands the adjustment dimension of the locking rod. The locking spring provides power to the locking block. When the locking support moves, the locking spring pushes the locking block to engage or disengage with the slot on the adjusting seat, thereby fixing or unlocking the position of the locking support in the adjusting seat and ensuring the stability of the locking rod in different positions.

[0014] Preferably, in any of the above embodiments, the locking rod includes a locking spring that provides power and a locking guide rod that is inserted into the locking hole. The locking spring is fixedly installed inside the locking support, and one end of the locking spring is fixedly installed with a locking guide rod that moves inside the locking support.

[0015] The above technical solution is adopted: the locking spring of the locking rod is installed inside the locking support to provide elastic force for the locking guide rod. When it is necessary to lock the electrical switch, the locking spring pushes the locking guide rod into the locking hole to realize the locking function. When unlocking, the external force overcomes the elastic force of the locking spring, causing the locking guide rod to retract. The operation is flexible and stable.

[0016] Preferably, in any of the above embodiments, the adjusting assembly includes a steel wire rope made of metal and an operating pull block. One end of the steel wire rope is fixedly installed with the locking guide rod, and the other end of the steel wire rope passes through the locking support, the adjusting seat, and the locking housing and is fixedly installed with the pull block.

[0017] The above technical solution is adopted: one end of the steel wire rope of the adjustment component is connected to the locking guide rod, and the other end passes through multiple components and is connected to the pulling block. When the pulling block is pulled, the steel wire rope drives the locking guide rod to extend and retract, thereby realizing the opening and closing operation of the locking device. The steel wire rope moves inside the device, avoiding interference from external factors and ensuring that the adjustment process is stable and reliable.
