Description

Technical Field

[0001] The utility model relates to the technical field of ammeters, in particular to a DC ammeter with a fall-proof structure. Background Technique

[0002] A DC ammeter is specifically used to measure the current intensity in a DC circuit and is an indispensable measuring tool in the electronic field. During the circuit design and maintenance process, it is very important to understand the current requirements of the load. The ammeter can help engineers evaluate the current consumption of each load in the circuit, so as to ensure that the power supply can meet the requirements. At the same time, the ammeter can be used to ensure that the current in the circuit does not exceed the safety limit, which is crucial for avoiding circuit overload and preventing damage to circuit components. For this reason, a DC ammeter with a fall-proof structure is proposed.

[0003] The existing Chinese utility model patent with the reference publication number of CN213517286U discloses a DC ammeter with a fall-proof structure, belonging to the technical field of ammeters. In this technical solution, it includes a DC ammeter main body, and the DC ammeter main body includes a DC ammeter, a housing, and a terminal. And a fall-proof mechanism is arranged outside the DC ammeter. A rubber sleeve is sleeved outside the DC ammeter, and first sliding rails are fixedly connected to the side of the rubber sleeve away from the DC ammeter. First sliders slide on the side of the first sliding rails away from the rubber sleeve, and a first connecting rod is connected to the side of the first slider away from the first sliding rail in a rotating manner. A second slider is connected to the side of the first connecting rod away from the first slider in a rotating manner, and the end of the second slider away from the first connecting rod slides on a second sliding rail. The utility model reduces the damage caused to the DC ammeter by impact when the DC ammeter is impacted, reduces the later monitoring and maintenance of the DC ammeter, improves the service life of the DC ammeter, and reduces the later material cost expenditure.

[0004] Based on the retrieval of the above patent and the combination with the equipment in the existing technology, it is found that during the installation or maintenance of the ammeter, it will be collided or accidentally dropped. After the ammeter is impacted, it will damage the internal parts, resulting in a shortened service life of the ammeter. The existence of these problems affects the use of the device.
