Description

A measurement auxiliary device for multimeters Technical Field

[0001] This utility model relates to the field of material performance measurement instrument technology, specifically a measurement auxiliary device applied to a multimeter. Background Technology

[0002] Currently, when using a multimeter to test material properties, it is necessary to manually fix the probes in contact with the test point and simultaneously observe the data on the display screen. Because manual operation makes it difficult to maintain stable contact between the probes and the test point for extended periods, uneven contact pressure can easily lead to data fluctuations or errors. At the same time, the operator must simultaneously focus on probe positioning and data reading; distraction can easily result in misjudgments or missed measurements. Furthermore, the traditional handheld probe method cannot maintain multi-angle testing and is difficult to flexibly adapt to the properties of materials with special structures.

[0003] According to published patent CN114002463A, a multimeter handheld voltage measurement auxiliary tool comprises a movable component and a handheld component. The movable component includes a swing arm, a transmission component, and multimeter probes. The transmission component is disposed on one side of the swing arm, and the multimeter probes are disposed at one end of the swing arm. The handheld component includes a grip and a size adjustment rod. The grip is connected to the side of the swing arm, and the end of the size adjustment rod is fixedly connected to the swing arm. During use, the handheld component is supported by one hand, and prolonged observation leads to hand fatigue, resulting in inaccurate measurements and making prolonged observation impossible. Therefore, those skilled in the art have provided a measurement auxiliary device for multimeters to solve the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this invention is to provide a measurement auxiliary device for multimeters to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A measurement auxiliary device for a multimeter includes a support control device, two supports, a fixed frame, and a measuring stabilizing leg. The support control device is located at the top of the supports and consists of a rotating shaft and a rotating clamp. A gear is installed inside the rotating clamp, and the gear is connected to a movable gear. The movable gear is fixed at the top of the supports. By turning the rotating shaft, the gear and the movable gear are driven to rotate, controlling the opening and closing angle of the supports. The distance between the two measuring probes is limited by the opening and closing angle of the supports.

[0007] As a further embodiment of this utility model: the fixed frame is fixedly installed at the bottom of the bracket. The size of the binding circumference of the fixed frame can be changed by rotating the knob on the side of the fixed frame. First, rotate the knob in the opposite direction to increase the binding circumference of the fixed frame. Then, put the two measuring pens into the fixed frame. The position of the fixed frame binding the measuring pens can be changed according to the measurement requirements. When fixing the measuring pens, rotate the knob on the side of the fixed frame in the forward direction to fix the measuring pens, so that the measuring pens are in a state where they cannot be pulled up or down.

[0008] As a further improvement of this utility model: the measuring stabilizing leg is fixedly connected to the telescopic cylinder via a movable support leg and a support leg. The movable support leg is movably connected to the fixed frame via an angle adjustment hub, allowing the angle between the movable support leg and the fixed frame to be changed according to measurement needs. The support leg and the fixed frame are fixedly connected at an acute angle. The lower end of the movable support leg and the support leg is nested and fixedly connected to the telescopic cylinder. The telescopic cylinder consists of two layers of slender tubes that are hollow and nested segment by segment, thicker at the top and thinner at the bottom. The length of the telescopic cylinder is fixed by friction. When fixing the measuring auxiliary device, the angle of the movable support leg can be adjusted to keep the measuring auxiliary device stable. Then, the length of the movable support leg and the telescopic cylinder of the support leg can be adjusted to keep the measuring auxiliary device stable when it is not supported by both hands. The base is located at the bottom of the telescopic cylinder and is fixedly connected to the telescopic cylinder. The base is made of high-hardness plastic material, which is not easily deformed, making the measuring auxiliary device more stable when it is not supported by both hands.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] When measuring material properties, this device can limit the distance between the two measuring pens by adjusting the support control device, change the angle of the movable support leg by changing the angle adjustment hub, and adjust the telescopic length of the telescopic cylinder. It can conveniently measure materials with irregular surfaces, improve measurement stability, free up hands during measurement, and accurately measure material properties for a long time, reducing labor costs and improving measurement accuracy.
