Dial gauge capable of lighting

Abstract

The invention discloses a dial gauge capable of lighting, which comprises a dial plate that is internally provided with a pointer. A measuring rod is arranged below the dial plate. The measuring rod is provided with a measuring head. The dial plate is provided with a lighting device which comprises the components of: a switch, a battery and a lamp. The switch is arranged at the side surface of the dial plate. The battery is arranged in the dial plate. The lamp is arranged in the dial plate. The measuring head is provided with a fluorescent layer. The lighting device can make the dial gauge operate normally at night or at a dark plate with weak light. The fluorescent layer emits light at night, and therefore the measuring head can accurately position an object to be measured, thereby realizing convenient measurement at night and improving measurement accuracy.

Description

technical field [0001] The invention relates to the field of industrial machinery, in particular to an illuminated dial indicator. Background technique [0002] With the development of social production and the rapid development of the machinery industry, a large number of industrial tools are produced and used. With the extensive development of measurement operations, the role of dial indicators in operations cannot be ignored. The application number is CN201310004403.9. A reverse dial indicator, including a bezel, a rack needle and a dial are installed in the bezel, a cap is installed on the rack needle, a small scale pointer and a large scale pointer are arranged on the outer wall of the dial, and a small scale gear is installed on the inner wall of the dial 1. The large scale gear and the transmission gear, the small scale gear drives the small scale pointer, the large scale gear drives the large scale pointer, the upper part of the small scale gear meshes with the large...

[0002] With the development of social production and the rapid development of the machinery industry, a large number of industrial tools are produced and used. With the extensive development of measurement operations, the role of dial indicators in operations cannot be ignored. The application number is CN201310004403.9. A reverse dial indicator, including a bezel, a rack needle and a dial are installed in the bezel, a cap is installed on the rack needle, a small scale pointer and a large scale pointer are arranged on the outer wall of the dial, and a small scale gear is installed on the inner wall of the dial 1. The large scale gear and the transmission gear, the small scale gear drives the small scale pointer, the large scale gear drives the large scale pointer, the upper part of the small scale gear meshes with the large scale gear, the lower part of the small scale gear meshes with the transmission gear, and the transmission gear and the outer wall of the rack needle The teeth of the rack pin are connected to the tension spring, and the other end of the tension spring is fixed to the inner wall of the upper part of the dial. A calibration hook is installed at the lower end of the rack pin. The calibration hook includes a vertical hook body, and the hook body is lowered There is a vertical detection rod, and the detection rod is in contact with the back of the workpiece. The advantage is that the calibration hooks of different lengths can be replaced according to the thickness of the workpiece, which can meet the measurement of most workpieces. It has good versatility, but the dial indicator cannot be used at night. Or work as usual in a dark place, the side measuring head cannot accurately locate the position of the object to be measured, it is inconvenient to measure at night, and the measurement accuracy is difficult to grasp
