Description

Technical Field

[0001] This utility model relates to the field of sensor installation technology, and in particular to a dual-excitation dual-sensing sensor and its installation structure that is easy to assemble and disassemble. Background Technology

[0002] The dual-excitation dual-induction sensor is a multi-parameter detection device based on the principle of electromagnetic induction. It uses dual excitation coils to generate a magnetic field and utilizes the signal difference between the two induction coils to achieve high-precision and interference-resistant measurement.

[0003] In the existing technology, conventional dual-excitation dual-sensor sensors are fastened with bolts or fixed with adhesive (such as epoxy resin). Disassembly requires special tools or high-temperature baking, which is time-consuming and easily damages the sensor housing. Furthermore, bolt installation is sensitive to vibration and is prone to signal drift due to loosening. Adhesive bonding is prone to failure in high-temperature and high-humidity environments.

[0004] Based on this, a dual-excitation dual-sensing sensor and its installation structure that are easy to assemble and disassemble are proposed. Utility Model Content

[0005] The purpose of this invention is to provide a dual-excitation dual-sensing sensor and its installation structure that are easy to assemble and disassemble, so as to solve the problems mentioned in the background art.

[0006] The technical solution of this utility model is: a dual-excitation dual-induction sensor that is easy to assemble and disassemble, including a sensor body, an electromagnetic coil box fixedly connected to the surface of the sensor body, a base fixedly connected to the surface of the sensor body, and a sleeve frame fixedly connected to the lower surface of the base.

[0007] An installation structure is provided for a dual-excitation dual-induction sensor that is easy to install and disassemble. The structure includes a magnetic box with multiple fixing bolts on its surface, an electromagnet fixedly mounted on the inner bottom wall of the magnetic box, a conductive connector fixedly mounted on the surface of the magnetic box and electrically connected to the electromagnet, and two stops fixedly connected to the inner wall of the magnetic box. Each of the two stops has a limit slot on its opposing surface. The inner wall of the magnetic box is slidably connected to the surface of a frame.

[0008] In some embodiments, the inner wall of the sleeve frame has two sliding grooves, and the inner walls of the two sliding grooves are slidably connected to sliders. The opposite surfaces of the two sliders are fixedly connected to the same mounting plate. The lower surface of the mounting plate is fixedly mounted with a magnet body, and the upper surface of the mounting plate is fixedly connected with a connecting rod. The top end of the connecting rod is fixedly connected with a protrusion.

[0009] In some embodiments, a fixing block is fixedly connected to the inner wall of the sleeve frame, and two through grooves are formed on the surface of the sleeve frame, with each of the two through grooves corresponding to two limiting grooves.

[0010] In some embodiments, a limiting groove is formed on the upper surface of the fixing block, a limiting rod is fixedly connected to the inner wall of the limiting groove, two limiting blocks are slidably connected to the surface of the limiting rod, a spring is fixedly connected to the opposite surface of the two limiting blocks, the spring is sleeved on the surface of the limiting rod, and a trapezoidal locking block is fixedly connected to the upper surface of each of the two limiting blocks, and the surfaces of the two trapezoidal locking blocks are slidably connected to the inner walls of the corresponding two through grooves.

[0011] Compared with existing technologies, the significant advantages of this invention are:

[0012] Firstly, this utility model uses the electromagnet to de-energize, thus no longer attracting the magnet body. At this time, the two trapezoidal blocks will reset under the action of the spring, thereby squeezing the trapezoidal blocks and causing them to rise. After resetting, the two trapezoidal blocks can retract back into the sleeve frame, thereby releasing the limit between them and the stop block, thus realizing the disassembly of the sensor and achieving convenient disassembly.

[0013] Secondly, this utility model energizes the electromagnet by connecting a conductive connector. The energized electromagnet magnetically attracts the magnet body, thereby pulling the mounting plate down. The descent of the mounting plate causes the connecting rod to drive the protrusion down. The descent of the protrusion can squeeze the two trapezoidal blocks through the through slot and into the limiting slot, thereby limiting the base and the frame, and then installing the sensor body.

[0021] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0022] This utility model provides an improved dual-excitation dual-sensing sensor and its mounting structure that are easy to assemble and disassemble. The technical solution of this utility model is as follows:

[0023] like Figures 1-4 As shown, a dual-excitation dual-induction sensor that is easy to assemble and disassemble includes a sensor body 1, an electromagnetic coil box 2 fixedly connected to the surface of the sensor body 1, a dual induction coil inside the electromagnetic coil box 2, a base 3 fixedly connected to the surface of the sensor body 1, the base 3 being fixedly connected to the sensor body 1, and a sleeve 7 fixedly connected to the lower surface of the base 3, the sleeve 7 serving as an installation medium.

[0024] like Figure 2 and Figure 3 As shown, an installation structure is used in a dual-excitation dual-induction sensor that is easy to install and disassemble. It includes a magnetic box 4, and multiple fixing bolts 5 are provided on the surface of the magnetic box 4. There are four fixing bolts 5, which can be used to install the magnetic box 4 on the object to be measured. An electromagnet 11 is fixedly installed on the inner bottom wall of the magnetic box 4. The electromagnet 11 is a high-temperature resistant electromagnet to prevent it from losing its magnetism at high temperatures. A conductive connector 6 is fixedly installed on the surface of the magnetic box 4. The conductive connector 6 can realize the switching on and off of the electromagnet 11 and is electrically connected to the electromagnet 11. Two stops 14 are fixedly connected to the inner wall of the magnetic box 4. Each of the two stops 14 has a limit slot 15 on its opposite surface. The inner wall of the magnetic box 4 is adapted to slide and connect with the surface of the sleeve 7.

[0025] like Figure 2 and Figure 4As shown, in one embodiment, the inner wall of the sleeve 7 has two sliding grooves 8, and the inner walls of the two sliding grooves 8 are slidably connected to sliders 23. The opposite surfaces of the two sliders 23 are fixedly connected to the same mounting plate 9. The sliding grooves 8 and sliders 23 can limit the mounting plate 9. The lower surface of the mounting plate 9 is fixedly mounted with a magnet body 10, which is also a high-temperature resistant magnet. The upper surface of the mounting plate 9 is fixedly connected with a connecting rod 13, and the top end of the connecting rod 13 is fixedly connected with a protrusion 18.

[0026] The inner wall of the sleeve frame 7 is fixedly connected to a fixing block 12. The surface of the sleeve frame 7 has two through grooves 16, which correspond to two corresponding limiting grooves 19 respectively. The inner wall of the through groove 16 is adapted to slide and connect with the surface of the trapezoidal card block 17.

[0027] like Figure 4 As shown, in one embodiment, a limiting groove 19 is formed on the upper surface of the fixing block 12, and a limiting rod 20 is fixedly connected to the inner wall of the limiting groove 19. The limiting rod 20 can improve the limiting effect on the limiting block 21. Two limiting blocks 21 are slidably connected to the surface of the limiting rod 20. Springs 22 are fixedly connected to the opposite surfaces of the two limiting blocks 21. The springs 22 are sleeved on the surface of the limiting rod 20. Trapezoidal locking blocks 17 are fixedly connected to the upper surfaces of the two limiting blocks 21. The surfaces of the two trapezoidal locking blocks 17 are slidably connected to the inner walls of the corresponding two through grooves 16. The springs 22 can realize the elastic expansion and reset of the two limiting blocks 21, thereby realizing the automatic reset of the protrusion 18 and achieving the effect of convenient disassembly.

[0028] The specific working method is as follows: When in use, first fix the magnetic box 4 to the object to be measured with fixing bolts 5. Then, insert the sensor body 1, the base 3 and the sleeve 7 on the lower surface of the base 3 into the magnetic box 4 at the same time. After the base 3 and the sleeve 7 on the lower surface of the base 3 are inserted into the magnetic box 4, the stop block 14 inside the magnetic box 4 can limit the base 3. At the same time, connect the conductive connector 6 to energize the electromagnet 11. The energized electromagnet 11 can magnetically attract the magnet body 10, thereby pulling the mounting plate 9 down. The descent of the mounting plate 9 can cause the connecting rod 13 to drive the protrusion 18 down. The descent of the protrusion 18 can squeeze the two trapezoidal blocks 17 through the through groove 16 and into the limiting slot 15, thereby limiting the base 3 and the sleeve 7, and then installing the sensor body 1.

[0029] During disassembly, the electromagnet 11 is de-energized and no longer attracts the magnet body 10. At this time, the two trapezoidal blocks 17 will be reset under the action of the spring 22, thereby squeezing the trapezoidal blocks 17 and causing them to rise. After resetting, the two trapezoidal blocks 17 can retract back into the sleeve 7, thereby releasing the limit between them and the stop block 14, thus realizing the disassembly of the sensor and achieving convenient disassembly.

Matters not covered in this utility model are common knowledge to those skilled in the art.
