Description

Technical Field

[0001] This utility model relates to the field of electrical measuring instrument technology, specifically to a multifunctional electrical measuring instrument. Background Technology

[0002] A multi-functional electrical measuring instrument is a portable or stationary device that integrates multiple electrical measurement functions. It is primarily used to detect and analyze various parameters in circuits or electronic equipment. By combining multiple sensors and intelligent processing technology, it simplifies the workflow for electricians, engineers, and electronics enthusiasts, avoiding the hassle of frequently replacing single-function instruments.

[0003] Existing multi-functional electrical measuring instruments lack protection for the display screen when not in use, making the glass surface prone to scratches. Scratches can increase glare, affecting readings in bright light (such as outdoors), especially when the scratches are dense or deep, potentially causing blurred display or glare interference. Severe scratches may obscure critical data (such as voltage and current values), leading to misreading or operational errors and affecting the accuracy of equipment testing.

[0004] Therefore, the applicant has made beneficial designs and found a way to solve the above problems. The technical solution to be introduced below is generated in this context. Utility Model Content

[0005] The present invention provides a multifunctional electrical measuring instrument to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multifunctional electrical measuring instrument includes an instrument body, a front cover with a display screen glass on its surface, sliding rods on both sides of the cover, a sliding plate on each sliding rod, a first connecting strip on the top of the cover, a second connecting strip on the top of the sliding plate, a foldable fabric between the first and second connecting strips, a first magnet on the top of each side of the cover, a second magnet on each side of the sliding plate, and a third magnet on the bottom of each side of the cover.

[0008] Preferably, the push-pull plate has ball bearings movably mounted on both sides of its rear portion, and the ball bearings are in contact with the surface of the cover.

[0009] Preferably, the push-pull plate has a push block at the front.

[0010] Preferably, the magnetic pole faces of the first magnet, the second magnet, and the third magnet are all arranged in the same direction.

[0011] Beneficial effects

[0012] The above-mentioned technical solutions of one or more of the multifunctional electrical measuring instruments provided in this utility model embodiment have at least one of the following technical effects:

[0013] Through the above-mentioned technical solution, this utility model allows the sliding plate to be pushed down when the instrument is not in use, causing the folded cloth to unfold and cover the display screen glass. This effectively protects the display screen glass, preventing scratches from easily appearing when the instrument is not in use. This avoids misreading and operational errors caused by scratches, ensures detection accuracy, and also improves the service life of the display screen glass. Attached Figure Description

[0023] like Figure 1-3 The diagram shown is a structural schematic of a multifunctional electrical measuring instrument according to a preferred embodiment of the present invention.

[0024] In this embodiment, the instrument body 1 is included. The basic functions of the instrument body 1 are the same as those of conventional models on the market, and this structure will not interfere with or affect its basic functions. The instrument body 1 has a front cover 2, and the surface of the front cover 2 has a display screen glass 3. There are two sliding rods 4 on both sides of the front cover 2. The two sliding rods 4 are vertical and parallel to each other. A push-pull plate 5 is slidably mounted on the sliding rod 4. The push-pull plate 5 slides along the sliding rod 4. The top of the front cover 2 has a first connecting strip 6, and the top of the push-pull plate 5 has a second connecting strip 7. A foldable fabric 8 is provided between the first connecting strip 6 and the second connecting strip 7. The two ends of the foldable fabric 8 are connected to the first connecting strip 6 and the second connecting strip 7, respectively. There are first magnets 9 on the top of both sides of the front cover 2. The push-pull plate The cover 5 has a second magnet 10 on both sides and a third magnet 11 on both sides of the bottom. When the push-pull plate 5 moves upward to fold the folded cloth 8, the first magnet 9 and the second magnet 10 attract each other to fix the push-pull plate 5. When the push-pull plate 5 moves downward to unfold the folded cloth 8, the second magnet 10 and the third magnet 11 attract each other to fix the push-pull plate 5. When the instrument is not in use, the push-pull plate 5 is pushed downward to unfold the folded cloth 8 to cover the display screen glass 3. This can effectively protect the display screen glass 3 and prevent scratches from easily appearing on the display screen glass 3 when the instrument is not in use. This avoids misreading and operational errors caused by scratches, ensures detection accuracy, and also improves the service life of the display screen glass 3.

[0025] In this embodiment, ball bearings 12 are movably provided on both sides of the rear part of the push-pull plate 5, and the ball bearings 12 are in contact with the surface of the cover 2.
