Description

Technical Field

[0001] The utility model relates to the technical field of coils, in particular to a high-precision power coil. Background Art

[0002] At present, power coils are often used for signal measurement. However, since the circumference of the end face of the object to be measured is not well matched with the power coil, and since the end face of the object to be measured is an irregular object, it is difficult to match it with the power coil, resulting in the power coil being difficult to fix and easy to slide after installation, thereby affecting the test accuracy of the coil; and when the object to be measured is installed in an environment with a small operating space, the existing power coil cannot be effectively installed or is difficult to install due to size reasons.

[0003] For this purpose, a high-precision power coil is specially proposed. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Embodiment 1: A mounting groove 6 is installed at one end of the outer side of the coil body 1, a first fixing clip 7 is installed at the bottom end inside the mounting groove 6, a second fixing clip 13 is installed above the inner side of the mounting groove 6, a fixing rod 10 is installed on the top of the second fixing clip 13, elastic limiting columns 9 are installed on both sides of the fixing rod 10, a pressing plate 5 is installed on the top of the fixing rod 10, a spring 11 is sleeved on the outer side of the fixing rod 10, a damping rod 3 is installed on the inner side of the coil body 1, and a rubber fixing plate 2 is installed on the top of the damping rod 3, the bottom ends of both sides of the rubber fixing plate 2 are connected to the top of a damping rod 3, and a plurality of first anti-slip particles 4 are installed at equal distances on one side of the rubber fixing plate 2, the interior of the coil body 1 is filled with elastic material, and one end of the coil body 1 is movably installed inside the mounting groove 6, and the coil body 1 is in a ring shape.

[0018] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, since the interior of the coil body 1 is filled with elastic material, the entire coil body 1 can be bent under force, and under the action of the canceller, the coil body 1 can return to its original state. Since the inner wall of the coil body 1 is installed with a damping rod 3, and the top end of the damping rod 3 is installed at both ends of the rubber fixing plate 2, the two rubber fixing plates 2 installed on the inner wall of the coil body 1 can be made to contact with the surface of the object to be measured by bending the coil body 1. When the surface of the object to be measured is an irregular surface, the rubber fixing plate 2 itself can still effectively contact the surface of the object to be measured through the characteristics of the rubber fixing plate 2. Since a plurality of first anti-slip particles 4 are equidistantly installed on one side of the rubber fixing plate 2, the first anti-slip particles 4 can increase the friction with the surface of the object to be measured, and prevent the coil body 1 from falling off after being installed with the object to be measured. Therefore, the coil can be installed on objects to be measured with different end faces, thereby expanding the scope of use of the coil.

[0019] Embodiment 2: Limiting holes 12 are provided on both sides of the mounting groove 6, and the limiting holes 12 are installed in cooperation with the elastic limiting columns 9. The top of the coil body 1 extends out of the interior of the mounting groove 6. The spring 11 is located between the bottom of the pressing plate 5 and the top of the mounting groove 6. The first fixing clip 7 and the second fixing clip 13 are both semicircular, and a plurality of second anti-slip particles 8 are installed at equal distances on the inner walls of the first fixing clip 7 and the second fixing clip 13.

[0020] Specifically, Figure 1 , Figure 2 and Figure 3As shown, since the interior of the coil body 1 is filled with elastic material, during the installation process with the object to be measured, one end of the coil body 1 can be inserted into the interior of the installation groove 6, and the outer side of one end of the coil body 1 can be placed between the first fixing clip 7 and the second fixing clip 13. The fixing rod 10 is moved downward by pressing the pressing plate 5. At the same time, the elastic limiting columns 9 installed on both sides of the fixing rod 10 will pop out into the limiting holes 12 opened on both sides of the installation groove 6. At this time, the second fixing clip 13 installed at the bottom end of the fixing rod 10 will tightly press the outer side of one end of the coil body 1. Since a plurality of second anti-slip particles 8 are evenly installed on the inner walls of the first fixing clip 7 and the second fixing clip 13, the second anti-slip particles 8 can prevent the coil body 1 from slipping out of the interior of the installation groove 6, and avoid the entire coil body 1 from being separated from the object to be measured during the measurement process. At the same time, by bending the coil body 1 and fixing the coil body 1 into a ring shape, the coil body 1 can avoid the limitation of the installation environment when being installed with the object to be measured, thereby improving the flexibility of the coil body 1 during installation and use.

[0021] Working principle: When in use, the inner side of the coil body 1 is wound around the end face of the object to be measured. By bending the coil body 1, the two rubber fixing plates 2 installed on the inner wall of the coil body 1 can contact the surface of the object to be measured. When the surface of the object to be measured is an irregular surface, the rubber fixing plate 2 can still effectively contact the surface of the object to be measured through its own characteristics. Since a plurality of first anti-skid particles 4 are installed at equal distances on one side of the rubber fixing plate 2, the first anti-skid particles 4 can increase the friction with the surface of the object to be measured, thereby preventing the coil body 1 from slipping against the object to be measured. In case the measured object falls off after installation, one end of the coil body 1 is inserted into the installation groove 6, so that the outer side of one end of the coil body 1 is placed between the first fixing clamp 7 and the second fixing clamp 13, and the fixing rod 10 is moved downward by pressing the pressing plate 5. At the same time, the elastic limiting columns 9 installed on both sides of the fixing rod 10 will pop out into the limiting holes 12 opened on both sides of the installation groove 6. At this time, the second fixing clamp 13 installed at the bottom end of the fixing rod 10 will tightly press the outer side of one end of the coil body 1 to prevent the entire coil body 1 from being separated from the measured object during the measurement process.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
