The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the invention, and cannot be understood as limiting the invention.

That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, an invented magnetic tile temperature monitor installation structure includes a motor housing 1 and a plurality of magnetic tiles 8 installed inside the motor housing 1, the outer surfaces of the magnetic tiles 8 are provided with connecting grooves 18, the outer wall surface of the motor housing 1 is provided with through holes 15 opposite to the connecting grooves 18, the outer wall surface of the motor housing 1 is provided with tube bodies 2 opposite to the through holes 15, the interior of the tube bodies 2 is provided with temperature sensors 3, one end of the temperature sensors 3 is inserted into the connecting grooves 18 through the through holes 15, and a connecting plate 19 is installed, and the outer sleeve of the motor housing 1 is provided with a middle shell 6 for tightening the magnetic tiles 8 outward and positioning the temperature sensors 3.

[0027] In this embodiment, the outer ring surface of the connecting groove 18 is expanded outward to form a positioning groove of an annular structure, and the first channels 20 connected to the outside are provided on both sides of the positioning groove. A plurality of positioning parts 21 are protruded on the outer ring surface of the connecting plate 19, and the positioning parts 21 are inserted into the positioning groove. The inner ring surface of the through hole 15 is provided with a second channel at a position opposite to the first channel 20, and the inner wall surface of the tube body 2 is provided with a third channel 17 at a position opposite to the second channel. The end of the temperature sensor 3 away from the motor is reduced inward, and a limiting mechanism plugged into the third channel 17 is installed on the reduced end of the temperature sensor 3.

[0028] In this embodiment, a ring body 14 is installed on a section of the temperature sensor 3 located inside the tube body 2, and a pressure groove 16 is provided on the outer ring surface of the ring body 14. A through groove 12 is provided on the outer ring surface of the tube body 2 opposite to the pressure groove 16. The side of the pressure groove 16 away from the motor housing 1 is inclined to provide a first guide portion, and the outer ring of the middle shell 6 passes through the through groove 12 and is inserted into the pressure groove 16. The end face of the middle shell 6 is inclined to form a second guide portion of an annular structure, and the second guide portion is arranged in conflict with the first guide portion.

[0029] In this embodiment, the limiting mechanism includes a ring 4 and a compression spring 13. The ring 4 and the compression spring 13 are both mounted on the reduced end of the temperature sensor 3. One end of the compression spring 13 is installed on the ring 4, and the other end is installed on the temperature sensor 3. The outer ring surface of the ring 4 protrudes opposite to the third channel 17 to form a limiting portion 5, and the limiting portion 5 is inserted into the third channel 17.

[0030] In this embodiment, a plurality of slide grooves 11 are axially provided on the reduced end of the temperature sensor 3, and the inner ring surface of the collar 4 protrudes opposite the slide groove 11 to form a slider, and the slider is slidably set in the slide groove 11. The collar can be positioned circumferentially through the slider and the slide groove, and the temperature sensor can also be positioned to ensure its stability after assembly.

[0031] In this embodiment, an outer shell 7 is installed on the outside of the middle shell 6, and the outer ring of the outer shell 7 extends to the outer end surface of the limiting mechanism. A connecting sleeve 9 is installed inside the middle shell 6. An internal thread is provided on the inner ring surface of the connecting sleeve 9, and an external thread is provided on the outer ring surface of the motor housing 1. The connecting sleeve 9 is meshed with the external thread on the motor housing 1 through the internal thread, and multiple gripping rods 10 are installed on the outer ring surface of the connecting sleeve 9.

[0032] In this embodiment, the length and width of the first channel 20, the second channel and the third channel 17 are all greater than the length and width of the positioning portion 21, so that the positioning portion can smoothly enter the first channel along the third channel and the second channel.

[0033] In this embodiment, the temperature measuring end surface of the temperature sensor 3 is arranged in contact with the outer side surface of the magnetic tile 8, so that the temperature sensor can directly contact the magnetic tile, so that each temperature sensor can accurately monitor each corresponding magnetic tile.

[0034] During installation, the positioning part on the temperature sensor is aligned with the third channel, the second channel and the first channel, so that after the stable sensor enters the tube body, the positioning part on the connecting plate can enter the third channel until the connecting plate smoothly enters the connecting groove, and the positioning part enters the first channels on both sides of the connecting groove;

[0035] When in the above state, the collar can be pulled outward, and the movement of the collar drives the limiting part, so that the limiting part can move outward along the reduced end of the stable sensor, so as to be arranged away from the tube body. At this time, the temperature sensor can be mixed, and the rotation of the temperature sensor drives the connecting plate and the positioning part, so that the positioning part can rotate into the positioning groove. After rotating to a certain angle, the limiting part can be arranged relative to the third channel. After releasing the collar, the limiting part can be inserted into the limiting groove by itself through the rebound of the compression spring. The temperature sensor can be positioned by the inserted limiting part, avoiding the occurrence of circumferential rotation and increasing stability.

[0036] In order to fix the temperature sensor and the magnetic tile synchronously, the connecting sleeve can be rotated by the grip rod to move the connecting sleeve along the thread until the middle shell is inserted into the pressure groove of the ring body along the through groove, and the extrusion between the second guide part on the hollow and the first guide part on the ring body can make the temperature sensor generate an outward thrust. The movement of the temperature sensor drives the connecting plate and the positioning part. The outward thrust of the positioning part on the magnetic tile can make the magnetic tile firmly fit on the inner wall surface of the motor shell, thereby ensuring that the fixing operation of multiple magnetic tiles and multiple temperature sensors can be completed at one time, which greatly increases the convenience;

[0037] Among them, during the rotation of the connecting sleeve, the outer shell is also driven. During the hollow extrusion of the ring body, the outer shell can move to the outside of the ring, thereby limiting the movement of the ring and avoiding the rotation of the temperature sensor caused by the limit part popping out from the third channel.

[0038] The above is only a specific implementation of the invention, but the protection scope of the invention is not limited to it. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the invention. Therefore, the protection scope of the invention should be based on the protection scope defined in the claims.
