Description

Technical Field

[0001] The utility model relates to the field of electrical measuring instruments, in particular to a digital multimeter. Background Art

[0002] Digital multimeters are widely used in the field of electrical measurement, and they are also common instruments for electricians. Digital multimeters, sometimes also called multimeters or three-meters, are multifunctional, multi-range electronic measuring instruments that can be used to measure physical quantities such as DC current, voltage, AC current, voltage, and resistance.

[0003] When using a digital multimeter, a multimeter and a matching probe are usually used. The multimeter and the probe are usually placed separately, which is inconvenient to carry. The probe is easy to be lost, and the probe lacks a protective device. The insulating layer on the surface is easy to fall off, which affects the service life. In addition, a flashlight is required in a dim environment, which is inconvenient to use. In addition, the multimeter is closely protected by the outer casing and is easily broken when dropped. Summary of the invention

[0004] The utility model aims to solve the deficiencies of the prior art and provides a digital multimeter.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a digital multimeter, including a multimeter body, a reinforcement shell is arranged on the outer side and the back side of the multimeter body, a light strip is arranged on the front side of the reinforcement shell and it surrounds the multimeter body, a wavy rubber buffer pad is arranged on the four sides of the reinforcement shell, a card slot is arranged on the back side of the reinforcement shell, a support plate is connected to the top of the back side of the reinforcement shell for damping rotation, and the support plate is stuck in the card slot after being reset, the support plate is hollow inside, a cover plate is hinged on one side of the support plate, and a probe matching the multimeter body is placed inside the support plate for storage.

[0006] In particular, a groove matching the light strip is provided on the front of the reinforcement shell, the light strip is laid in the groove, and a transparent cover is provided on the top of the groove.

[0007] In particular, a protruding battery box is provided at the bottom of the back side of the reinforcement shell, a battery is installed in the battery box, and the light strip is powered by the battery.

[0008] In particular, the back of the battery box is flush with the back of the support plate after reset.

[0009] Specially, rubber bumpers on the front and back bulges reinforce the shell.

[0010] The beneficial effects of the utility model are as follows: the utility model is convenient for use in dim environments by providing a fixed shell, a light strip, a rubber buffer pad, and a support plate, and does not require an additional flashlight. The utility model can protect the digital multimeter and act as a buffer when it falls. At the same time, the support plate can protect the probe and extend its service life. The probe can be easily stored together with the digital multimeter to avoid being lost. BRIEF DESCRIPTION OF THE DRAWINGS
