[0002] In the operation monitoring and equipment maintenance of power systems, power meters, as key metering and testing tools, directly affect the safe and stable operation of the power system and the rational allocation of power resources through their measurement accuracy and efficiency. Among them, the measuring probe, as the core component of power meters for acquiring electrical parameters (such as voltage, current, power, harmonics, etc.), plays a decisive role in the overall measurement effect.

[0004] In the prior art, during the use of a probe calibrator for proximity measuring instruments, the calibrator structure is relatively fixed, the slide body can only move in a single direction, and the positions of the probe holder and probe through hole lack angle adjustment function, making it difficult to adapt to scenarios requiring multi-angle calibration. It cannot meet the calibration requirements in non-linear directions, and its flexibility is significantly limited. Therefore, we have made improvements to this and proposed a multi-angle measuring probe for power instruments. Utility Model Content

[0008] The application is as follows:

[0009] A multi-angle measuring probe for an electrical instrument includes an electrical instrument body. A probe body and a probe head are disposed on one side of the electrical instrument body.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0031] Example 1: Please refer to the appendix of the instruction manual. Figure 1 -3, a multi-angle measuring probe for an electrical instrument, comprising an electrical instrument body 1, a probe body 3 and a probe head 4 disposed on one side of the electrical instrument body 1, a cable 2 fixedly connected to the side of the probe head 4 near the probe body 3, and the probe head 4 and the cable 2 electrically connected, a wiring port is provided on the electrical instrument body 1, and the cable 2 is inserted into the wiring port of the electrical instrument body 1 and electrically connected thereto, an annular connecting seat 5 is fixedly installed on one side of the probe head 4, a limiting ring 6 is fixedly installed on the outer side of the annular connecting seat 5 near the probe body 3, both the annular connecting seat 5 and the limiting ring 6 are inserted into the probe body 3 and rotatably connected thereto, annular magnets 7 are embedded on the sides of the probe body 3 and the limiting ring 6 that are close to each other, and the two annular magnets 7 are magnetically connected, two hemispherical steel balls 8 are disposed inside the probe body 3, and the two hemispherical steel balls 8 pass through one side of the probe body 3 and are slidably connected thereto, and the annular connecting seat 5 is provided with a plurality of grooves 24 grooves that cooperate with the hemispherical steel balls 8.

[0032] In this embodiment of the present invention, when it is necessary to adjust the angle of the probe head 4, since the annular connecting seat 5 and the limiting ring 6 are inserted into the probe body 3 and can rotate, and the two annular magnets 7 are magnetically connected, they provide a certain rotational resistance and positioning function. When the probe head 4 is rotated, the annular connecting seat 5 rotates accordingly, and the groove on its outer side interacts with the hemispherical steel ball 8. The hemispherical steel ball 8 rolls in the groove. When it is rotated to a suitable angle, the hemispherical steel ball 8 is stuck into the groove under the action of the compression spring 10, thereby fixing the angle.

[0033] In this embodiment of the utility model, the structural design allows the probe head 4 to be fixed at multiple angles, making it convenient to adjust to the optimal measurement angle in different measurement scenarios. For example, when measuring some electrical parameters located in corners or parts blocked by other devices, the angle of the probe head 4 can be flexibly adjusted to make the measurement more accurate and convenient. At the same time, the magnetic connection of the ring magnet 7 not only assists the feel when adjusting the angle, but also prevents the probe head 4 from rotating accidentally to a certain extent.

[0034] Example 2: Please refer to the appendix of the instruction manual. Figure 1 -5. As a preferred embodiment of this utility model, T-shaped rods 9 are fixedly installed on the side of each of the two hemispherical steel balls 8 away from the probe head 4. The T-shaped rods 9 are square in structure. Compression springs 10 are fixedly installed on the side of each of the two T-shaped rods 9 away from the hemispherical steel balls 8. The ends of the two compression springs 10 away from the T-shaped rods 9 are fixedly connected to the probe body 3. Magnetic isolation rings are embedded on the side of the probe body 3 close to the probe head 4 and on the corresponding sides of the annular magnet 7.

[0035] The bottom of the probe head 4 is inlaid with a first connecting half ring 14. The bottom of the probe head 4 and the bottom of the first connecting half ring 14 is provided with a second connecting half ring 15. A fixing rod 12 is provided between the first connecting half ring 14 and the second connecting half ring 15. Support plates 13 are fixedly installed on the corresponding sides of the fixing rod 12. Several insert plates are fixedly installed on the side of the first connecting half ring 14 and the second connecting half ring 15 that are close to each other. The insert plates are inserted into the interior of the fixing rod 12 and slidably connected to it.

[0036] The second connecting half-ring 15 is fixedly installed with two plugs 16 on the side close to the probe head 4 and on the corresponding sides of the first connecting half-ring 14. Both plugs 16 are inserted into the probe head 4 and slidably connected thereto. The bottom of both plugs 16 is provided with fixing bolts 17, which pass through the plugs 16 and are threadedly connected thereto. Both fixing bolts 17 are inserted into the probe head 4 and threadedly connected thereto.

[0037] The probe body 3 has a hollow cavity, and the cable 2 passes through the hollow cavity and is slidably connected to it. A cross-shaped rotating ring 11 is rotatably connected to the inner side of the probe body 3 away from the probe head 4, and the cable 2 passes through the cross-shaped rotating ring 11 and is fixedly connected to it.

[0038] A fixing strap 18 is fixedly installed on the outside of the probe body 3. A hook-and-loop fastener 19 is embedded in the fixing strap 18 away from the probe body 3. A hook-and-loop fastener 20 and an elastic pad 21 are fixedly installed on the side of the fixing strap 18 close to the probe body 3.

[0039] In this embodiment of the invention, the T-shaped rod 9 and the compression spring 10 form an elastic positioning structure; when the hemispherical steel ball 8 is squeezed by the groove of the annular connecting seat 5, the T-shaped rod 9 will compress the compression spring 10, so that the hemispherical steel ball 8 can move smoothly from one groove to another.

[0040] The design of the fixed rod 12 being slidably connected to the first connecting half-ring 14 and the second connecting half-ring 15 via a sliding insert provides flexible space for adjusting the angle of the fixed rod 12. When it is necessary to adjust the support angle of the support plate 13, this can be achieved by changing the position of the fixed rod 12 between the two half-rings: the sliding of the insert inside the fixed rod 12 can drive the fixed rod 12 to rotate around the connection point, thereby changing its relative angle with the probe head 4, and ultimately achieving precise adjustment of the support angle of the support plate 13.

[0041] The insert 16 is inserted into the probe head 4 and fixed by the fixing bolt 17, thus achieving a stable connection between the second connecting half ring 15 and the probe head 4.

[0042] Cable 2 passes through the hollow cavity of probe body 3 and is fixedly connected to cross-shaped rotating ring 11. When probe body 3 rotates, cross-shaped rotating ring 11 rotates accordingly, causing cable 2 to rotate as well, thus preventing cable 2 from getting tangled or twisted during the rotation of probe body 3.

[0043] The securing strap 18, with its hook and loop fasteners 19 and 20, allows for easy bundling and organization of the cables 2, resulting in a more orderly and organized cable layout. The elastic padding layer 21 provides cushioning and protection, preventing the cables 2 from directly contacting the securing surface and causing wear.

[0044] In this embodiment of the utility model, the square structure of the T-shaped rod 9 ensures its stability during movement and prevents rotation; the elastic force provided by the compression spring 10 allows the hemispherical steel ball 8 to reliably fit into the groove, ensuring the stability of the fixed angle; the magnetic shielding ring effectively avoids magnetic field interference, improves the reliability and stability of the entire structure, and further ensures the stable operation of the probe in different environments.

[0045] When dealing with electrical equipment with different tilt angles or irregular surfaces, the support angle of the support plate 13 can be adjusted to ensure that it fits tightly against the surface of the equipment, thus ensuring that the probe head 4 maintains a stable posture during the measurement process and avoiding measurement deviations caused by unstable support.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
