Description

Technical Field

[0001] The utility model relates to the technical field of circuit breaker detection, in particular to a circuit breaker detection tool. Background Art

[0002] A circuit breaker is a switching device that can close, carry and interrupt current under normal circuit conditions and can close, carry and interrupt current under abnormal circuit conditions within a specified time.

[0003] After production, circuit breakers need to be tested for closing and opening to determine whether they are qualified. The traditional testing method is for the operator to insert the terminal block into the wiring port of the circuit breaker, and then manually open and close the knife to determine the quality of the circuit breaker. However, this testing method has the following defects: when the operator plugs in and out the terminal block, it is easy to cause electric shock, and it is too time-consuming for the operator to manually open and close the knife one by one to test the circuit breaker, which cannot improve the efficiency of the test. To this end, we propose a circuit breaker testing tool. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a technical solution: a circuit breaker detection tool, including a mounting seat 1, a positioning block 2 is fixedly installed on the upper surface of the mounting seat 1, and a plurality of grooves 3 that are compatible with the circuit breaker 17 are equidistantly opened on the upper surface of the positioning block 2. The circuit breaker 17 can be fixed by placing the circuit breaker 17 into the groove 3. Two groups of sliding grooves are symmetrically opened on the upper surface of the mounting seat 1, and the inner walls of the two groups of sliding grooves are slidably connected with sliders 4. Mounting plates 5 are fixedly installed on the upper surfaces of the two sliders 4, and contact terminals 6 are arranged on the opposite surfaces of the two mounting plates 5. Through grooves 7 for the contact terminals 6 to pass through are opened on the two inner side walls of the groove 3.

[0025] The lower surface of the mounting base 1 is provided with a driving structure that can drive the two mounting plates 5 to move, and the driving structure includes a mounting frame 8 fixedly mounted on the lower surface of the mounting base 1, and the inner wall of the mounting frame 8 is rotatably connected with a threaded column 9, and the surface of the threaded column 9 is respectively threadedly connected with two nut seats 10, and the upper surfaces of the two nut seats 10 are respectively fixedly connected to the lower surfaces of the two sliders 4, and the surface of the threaded column 9 is provided with two sections of threads, and the thread rotation directions of the two sections of threads are opposite, and the two nut seats 10 are respectively spirally driven with the two sections of threads on the surface of the threaded column 9, and a motor 15 is fixedly mounted on the left side surface of the mounting base 1, and the output end of the motor 15 is fixedly connected to the left end of the threaded column 9.

[0026] The forward rotation of the driving motor 15 can drive the threaded column 9 to rotate, and the spiral transmission between the threaded column 9 and the nut seat 10 can drive the two sliders 4 and the mounting plates 5 on the upper surfaces of the two sliders 4 to move synchronously. When the mounting plates 5 are close to each other, the contact terminals 6 will be driven to pass through the through slots 7 and inserted into the wiring ports on the circuit breaker 17. Conversely, when the motor 15 is reversed, the contact terminals 6 on the two mounting plates 5 can be driven to detach from the wiring ports on the circuit breaker 17.

[0027] The upper surface of the mounting base 1 is provided with a power-on detection structure, which includes a connecting frame 13 fixedly mounted on the upper surface of the mounting base 1, and a display light 14 fixedly mounted on the upper surface of the connecting frame 13.

Driving the electric telescopic rod 11 can drive the push plate 12 to push the knife 18 on the circuit breaker 17 to perform opening and closing tests. When opening and closing the gate, the opening and closing of the display light 14 is observed to determine whether the opening and closing of the knife 18 are normal. At this time, the track block 16 will slide along the inner wall of the track groove, thereby guiding the movement trajectory of the push plate 12.

[0029] Compared with the prior art, the device places a plurality of circuit breakers 17 into the groove 3, and then utilizes the driving structure to drive the contact terminals 6 on the two mounting plates 5 to be respectively inserted into the wiring ports on the circuit breaker 17, so that the power supply can be turned on and whether the circuit breaker 17 is qualified can be determined according to the opening and closing of the display light 14. At the same time, the two push plates 12 on the two mounting plates 5 can be used to push the knife switch 18 on the circuit breaker 17 to open and close the switch, so that the knife switch 18 on the circuit breaker 17 can be tested for opening and closing, which greatly improves the efficiency of detection.
