The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0023] The present application will be further described below in connection with the drawings and specific embodiments.

[0024] Please refer to Figs. 1-3 It is shown that the embodiments of the present application provide a rotatable temperature measuring probe for train axle box, which comprises a rotating part 2, the rotating part 2 comprises a containing cylinder 22, a mounting bolt 4, a position spring 8 and a hexagonal nut 3, the bottom center of the containing cylinder 22 is provided with a positioning cylinder 24, the top center of the mounting bolt 4 is provided with a central hole 42, the positioning cylinder 24 is movably connected to the inside of the central hole 42, the bottom of the containing cylinder 22 around is provided with a limiting skirt 23, the top of the hexagonal nut 3 is provided with a stop 31, the hexagonal nut 3 is sleeved with the outside of the containing cylinder 22, the limiting skirt 23 hinders the stop 31 from descending, the mounting bolt 4 is fixedly installed at the bottom of the hexagonal nut 3, a ring groove I 25 is formed around the bottom of the containing cylinder 22, a ring groove II 41 is formed at the top of the mounting bolt 4 corresponding to the ring groove I 25, the position spring 8 is in the hexagonal nut 3, and the two ends of the position spring 8 are respectively inserted into the inside of the ring groove I 25 and the ring groove II 41, a connecting screw hole 21 is formed at one side of the containing cylinder 22 and close to the top, the connecting screw hole 21 is threadedly connected with one end of a wire outlet connector 5, a sensor 6 is installed in the containing cylinder 22, the sensor 6 is provided with a communication wire 61, the end of the communication wire 61 is led out from the wire outlet connector 5, a sealing ring 7 is sleeved outside the wire outlet connector 5, the sealing ring 7 is inserted into the wire outlet connector 5 to seal it, and the mounting bolt 4 is threadedly connected on a train bogie axle box.

[0025] In a preferred embodiment of the present application, the mounting bolt 4 is in an umbrella-shaped structure, and the umbrella head of the mounting bolt 4 is inserted into the bottom of the hexagonal nut 3 and is welded and fixed.

[0026] In a preferred embodiment of this utility model, the umbrella head of the mounting bolt 4 is threadedly connected to the bottom of the hexagonal nut 3.

[0027] Specifically, as shown in the figure, by inserting the positioning cylinder 24 of the rotating part 2 into the central hole 42 at the top center of the mounting bolt 4, the rotating part 2 rotates on the top of the mounting bolt 4. At the same time, by sleeved on the outside of the rotating part 2 with a hexagonal nut 3, and by setting a stop 31 around the top of the hexagonal nut 3, and by setting a limiting skirt 23 around the bottom of the receiving cylinder 22, the interference fit between the limiting skirt 23 and the stop 31 prevents the hexagonal nut 3 from sliding out from the bottom of the receiving cylinder 22. Meanwhile, by threading or welding the top of the mounting bolt 4 to the bottom of the hexagonal nut 3, the lower part of the receiving cylinder 22 is restricted inside the hexagonal nut 3, while still being able to rotate. This structure allows for the adjustment of the routing of the communication cable 61 during the installation of the probe, facilitating wiring, and preventing the communication cable 61 from rubbing against the probe components during equipment vibration, thus preventing damage to the communication cable 61 and reducing the service life of the equipment.

[0028] Furthermore, by setting a relief spring 8 between the bottom of the receiving cylinder 22 and the top of the mounting bolt 4, and by respectively locking the two ends of the relief spring 8 into the annular groove 25 and the annular groove 41, the relief spring 8 presses the rotating part 2 against the hexagonal nut 3. When the probe vibrates with the axle box of the train bogie, the relief spring 8 buffers the vibration, thereby effectively preventing damage to the components caused by collision between the rotating part 2 and the mounting bolt 4, which would reduce the waterproof performance of the probe and lead to water leakage and damage to its internal sensor 6, thus effectively extending the service life of the equipment.

[0029] With the above structural design, the rotatable temperature probe for the axle box of this train is connected to the top of the mounting bolt 4 by rotating the rotating part 2, and the two are connected by a hexagonal nut 3 to prevent them from separating. Then, a relief spring 8 is set between the two to absorb the vibration transmitted from the axle box of the train, thereby effectively preventing the rotating part 2 from colliding with the bottom mounting bolt 4 due to vibration, thus effectively protecting the components of this probe, thereby effectively improving the service life and waterproof performance of this probe.

[0030] Secondly, by setting the rotating part 2, and cooperating with the setting of the hexagonal nut 3 and the mounting bolt 4, the rotating part 2 can rotate freely 360 degrees without detaching from the overall structure of the probe, thus facilitating the wiring of the probe.

[0031] Furthermore, by installing the sensor 6 inside the rotating part 2 and encapsulating it with potting compound, the waterproof performance of this probe is effectively improved.

[0032] In a preferred embodiment of the utility model, further, a cover plate 1 is welded at the top opening of the containing cylinder 22.

[0033] In a preferred embodiment of the utility model, the containing cylinder 22 is communicated with the positioning cylinder 24, and the rotating part 2 is filled with potting glue.

[0034] Specifically, to further increase the waterproof performance of the probe, the rotating part 2 is set as a hollow structure with an opening at the top, the sensor 6 is placed inside, the communication wire 61 is connected with the corresponding equipment through the outlet joint 5 from the connecting screw hole 21, then the rotating part 2 is sealed by potting glue, and the top of the rotating part 2 is welded and sealed by welding means, so that the sensor 6 has super high waterproof sealing performance, and the service life of the probe is further improved.

[0035] In a preferred embodiment of the utility model, the outlet joint 5 is provided with an assembly nut 52 near the middle part.

[0036] In a preferred embodiment of the utility model, a mounting plane 26 is formed on one side of the containing cylinder 22, and the connecting screw hole 21 is formed on the mounting plane 26.

[0037] Specifically, after the mounting plane 26 is milled on one side of the containing cylinder 22, the outlet joint 5 is threadedly connected with the connecting screw hole 21, the contact surface between the plane and the assembly nut 52 is larger, the friction is increased, the outlet joint 5 is effectively prevented from loosening due to vibration, the structure of the probe is more firm and reliable, and the use safety performance of the probe is effectively improved.

[0038] In a preferred embodiment of the utility model, the outlet end of the outlet joint 5 is formed into a tapered tightening part 51 by buckling and tightening, and the sealing ring 7 is tightly pressed in the tightening part 51.

[0039] Specifically, after the sealing ring 7 is sleeved on the communication wire 61 and inserted into the outlet joint 5, the sealing ring 7 is further extruded and locked in the outlet joint by the tightening part 51 formed by buckling and tightening, the waterproof performance of the contact part between the outlet joint 5 and the communication wire 61 is enhanced, and the waterproof performance of the probe is further improved.
