[0002] The magnetic flux sensor is a non-contact device for measuring cable force. It adopts a sleeve structure. The cable to be measured passes through the sensor. During measurement, the sensor is fixed on the cable to be measured and cannot swing up and down or move at will.

[0003] The magnetic flux sensor is usually fixed by wrapping tape or metal clamps. However, there is a gap between the magnetic flux sensor and the cable, which makes it easy to swing left and right, affecting the accurate measurement of the magnetic flux sensor. Utility Model Content

[0004] In view of the above situation, it is necessary to provide a magnetic flux sensor limiting device to address the problem in the prior art that a gap exists after the magnetic flux sensor is fixed, which affects the measurement result.

When the snap-on protrusion and the snap-on recess are snapped into each other, the gap between the magnetic flux sensor and the cable is filled, forming a limit for the magnetic flux sensor and a relative fixation in the center, and no left and right swinging occurs.

[0008] Furthermore, the first limiting block further includes a first platform portion, which is connected to the bottom of the first tapered portion; the second limiting block further includes a second platform portion, which is connected to the bottom of the second tapered portion.

[0020] A magnetic flux sensor limiting device, the magnetic flux sensor 4 is sleeved on the cable 3, such as Figure 1 and Figure 2 As shown, the magnetic flux sensor limiting device includes a limiting component 1 and a pressing block component 2.

[0021] Specifically, the limiter assembly 1 includes a first limiter block 11 and a second limiter block 12, which are located at opposite ends of the magnetic flux sensor 4. The first limiter block 11 includes a first tapered portion 111, a plurality of engaging protrusions 112, and a first platform portion 113. A first through hole (not shown) is provided at the top of the first tapered portion 111, and a plurality of engaging protrusions 112 are provided along the periphery of the first through hole. The first platform portion 113 is connected to the bottom of the first tapered portion 111, and the first through hole extends through the first platform portion 113. The second limiter block 12 includes a second tapered portion 121, an extension portion 122, and a second platform portion 123. The top of the second conical portion 121 is connected to the extension portion 122. The extension portion 122 is provided with a second through-hole (not shown). The circumference of the extension portion 122 is provided with multiple engaging recesses 1221. The second platform portion 123 is connected to the bottom of the second conical portion 121. The second through-hole extends through the second conical portion 121 and the second platform portion 123. The first through-hole and the second through-hole have the same aperture. The engaging protrusion 112 and the engaging recess 1221 are adapted to fit together. The length of the engaging protrusion 112 and the engaging recess 1221 are both the same as the length of the magnetic flux sensor 4. The engaging protrusion 112 and the engaging recess 1221 engage to limit the magnetic flux sensor 4. Holding the first platform part 113 and the second platform part 123, the first limit block 11 and the second limit block 12 are placed on the cable 3 through the first through hole and the second through hole, and approach the magnetic flux sensor 4 from the upper and lower ends, and continue to move the first limit block 11 and the second limit block 12 so that the snap-on protrusion 112 and the snap-on recess 1221 respectively extend into the gap between the magnetic flux sensor 4 and the cable 3. When the snap-on protrusion 112 and the snap-on recess 1221 are snapped into each other, the gap between the magnetic flux sensor 4 and the cable 3 is filled. Because the apertures of the first through hole and the second through hole are the same, the first limit block 11 and the second limit block 12 are concentric, and the length of the snap-on protrusion 112 and the length of the snap-on recess 1221 are the same as the length of the magnetic flux sensor 4. That is to say, the snap-on protrusion 112 and the snap-on recess 1221 are snapped into each other to form a limit and relative fixation of the magnetic flux sensor 4 to prevent it from swinging left and right.

[0022] Specifically, the pressure block assembly 2 is sleeved with the limit assembly 1. The pressure block assembly 2 includes two pressure blocks 21. Each pressure block 21 is provided with multiple fixing holes 211 and a third through hole 212. One pressure block 21 is detachably connected to the first limit block 11, that is, one pressure block 21 is sleeved on the outer periphery of the clamping protrusion 112 through the third through hole 212, and the other pressure block 21 is detachably connected to the second limit block 12, that is, the other pressure block 21 is sleeved on the outer periphery of the clamping recess 1221 through the third through hole 212. The two pressure blocks 21 are respectively sleeved on the outer periphery of the clamping protrusion 112 and the outer periphery of the clamping recess 1221, and then the two pressure blocks 21 are fixed with screws through the fixing holes 211. The two pressure blocks 21 further fix the magnetic flux sensor 4 from opposite sides of the magnetic flux sensor 4.

[0023] 3. The utility model discloses that the two pressing blocks 21 are respectively sleeved on the bottom of the clamping protrusion 112 and the bottom of the extension part 122, and the first platform part 113 and the second platform part 123 are held by hand. The first limit block 11 and the second limit block 12 are sleeved on the cable 3 through the first through hole and the second through hole, and approach the magnetic flux sensor 4 from the upper and lower ends, and continue to move the first limit block 11 and the second limit block 12 so that the clamping protrusion 112 and the clamping recess 1221 are respectively extended into the gap between the magnetic flux sensor 4 and the cable 3. When the clamping protrusion 112 and the clamping recess 1221 are clamped with each other, the gap between the magnetic flux sensor 4 and the cable 3 is filled, forming a relative fixation of the magnetic flux sensor 4 and the centering, and then the two pressing blocks 21 are fixed with screws through the fixing holes 211. The two pressing blocks 21 further fix the magnetic flux sensor 4 from the opposite sides of the magnetic flux sensor 4, thereby preventing the magnetic flux sensor 4 from swinging left and right on the cable 3.
