[0002] A circuit breaker (usually more widely referred to as an "electronic component" or specifically such as a "relay", "circuit breaker", etc.) is an electronic device used to control, protect or isolate current in a circuit. A life detector is a specially designed device used to simulate actual working conditions and evaluate the performance and durability of a circuit breaker under long-term use through a series of tests, so as to predict its service life or detect potential early failures and ensure the safety and reliability of the circuit breaker. In short, a circuit breaker is a key component in a circuit, and a life detector is an important tool for evaluating the long-term performance and life of these components.

[0003] Most of them adopt a single detection method at a fixed position, and the contact stability between the probe and the connection point of the circuit breaker is insufficient, which easily leads to deviation of detection data. At the same time, the detection angle and range of the detection sensor are limited, and it is impossible to comprehensively collect the parameters of different positions of the circuit breaker, making it difficult to comprehensively evaluate the condition of the circuit breaker, greatly reducing the accuracy and comprehensiveness of the detection result, and being unable to effectively guarantee the safety detection requirements of the circuit breaker. Therefore, it is necessary to improve this situation. For this reason, a life detector structure for safety detection of circuit breakers is proposed. Summary of the Utility Model

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: A life detector structure for safety detection of circuit breakers includes an installation box. A ring is slidably arranged at the bottom of the installation box. Electric push rods are evenly arranged in the installation box, and the end parts of the output shafts of the electric push rods are fixedly installed with the ring. A cross bar is fixedly installed at the bottom of the ring. A sleeve rod is arranged on the cross bar. A spring is arranged in the sleeve rod. A probe is slidably arranged on the sleeve rod. The spring is pressed between the sleeve rod and the probe. A composite detection sensor is clamped on the side of the sleeve rod. A driving member for driving the composite detection sensor to rotate 360 degrees around the circuit breaker for detection is arranged in the installation box.

[0006] Preferably, the driving member includes a disc and a gear rotatably arranged at the top inside the installation box, and a motor fixedly installed inside the installation box.

[0007] Preferably, the end of the output shaft of the motor is fixedly installed with the middle part of the gear. The gear is meshed and drivingly connected with the disc. The electric push rods are fixedly installed with the disc. The sleeve rod is slidably arranged on the cross bar.

[0008] Preferably, there is a damping between the sleeve rod and the cross bar, and there is a damping between the probe and the sleeve rod.

[0009] Preferably, the composite detection sensor includes a temperature sensor, a current sensor, and a voltage sensor.

[0010] Preferably, symmetric handles are fixedly installed on the top surface of the installation box.

[0011] Preferably, a display controller is arranged on the top surface of the installation box. The display controller is electrically connected to the electric push rod, the probe, the composite detection sensor, and the motor respectively.
