[0002] The bearing temperature probe is used to monitor the working temperature of the bearing in real time. The bearing plays an important role in supporting and rotating in mechanical equipment. During operation, due to factors such as friction and load, the bearing may generate heat. If the temperature is too high, it may cause damage to the bearing, thereby affecting the normal operation of the entire equipment. The bearing is usually installed using a connecting frame.
[0003] In the prior art, the temperature probe is aligned with the bearing detection position, and the temperature probe is fixedly installed on the connecting frame by screws to keep the position of the temperature probe stable.
[0004] However, when this temperature probe connecting frame is used, due to the vibration generated by the equipment operation and the continuous rotation of the bearing, the screws may become loose, resulting in the position of the temperature probe deviating from the bearing detection position. Summary of the Utility Model
[0005] The purpose of the utility model is to address the problem in the background art that the position of the temperature probe deviates from the bearing detection position due to vibration, and to propose a connecting structure for a bearing detection temperature probe.

[0007] A fixed cylinder, a support cylinder is fixedly installed at the top of the fixed cylinder, and a detection probe is passed through the center of the fixed cylinder;
[0008] A positioning assembly, including a clamp, a guide rod, a docking assembly, an internal thread ring and a positioning plate. The side of the clamp is fixedly installed with the guide rod. The rod body of the guide rod is slidably connected to the support cylinder. The outer wall of the support cylinder is slidably connected to the internal thread ring. The inner wall of the internal thread ring is provided with a docking assembly. The side of the internal thread ring is fixedly installed with the positioning plate, and the end of the positioning plate contacts the guide rod;
[0009] The side of the clamp away from the guide rod contacts the detection probe, and a bearing is provided at the end of the docking assembly.

[0011] Optionally, the docking component includes a docking ring and an external thread ring. Both the docking ring and the external thread ring are circular in structure. The docking ring and the external thread ring are fixedly connected by an arc plate. The external thread ring rotates at the end of the support cylinder. The end of the docking ring contacts the rotating part of the bearing. The outer wall of the external thread ring is threadedly connected to the internal thread ring.
[0012] Optionally, a chute is provided on the outer wall of the support cylinder. The chute is parallel to the axis of the support cylinder. The internal thread ring slides in the chute.
[0013] Optionally, the fixture includes a bent plate and a spring piece. The bent plate is U-shaped in structure. The spring piece is fixedly installed at the opening of the bent plate. The side of the spring piece contacts the detection probe. The side of the bent plate away from the spring piece is fixedly connected to a guide rod.

[0030] Embodiment 1
[0031] This embodiment provides a connecting structure for a bearing detection temperature probe, as Figure 1 shown, which includes a fixing cylinder 1. A support cylinder 2 is fixedly installed at the top of the fixing cylinder 1. A detection probe 3 is passed through the center of the fixing cylinder 1. The axis lines of the fixing cylinder 1 and the support cylinder 2 are on the same straight line, and the detection probe 3 is located on the axis line of the support cylinder 2.
[0032] As Figure 2 and 3 shown, a positioning assembly 4 is provided at the end of the support cylinder 2. The positioning assembly 4 includes a clamp 41, a guide rod 42, a docking assembly, an internal thread ring 46 and a positioning plate 47. A guide rod 42 is fixedly installed on the side of the clamp 41, and the rod body of the guide rod 42 is slidably connected to the support cylinder 2. The side of the clamp 41 away from the guide rod 42 contacts the detection probe 3, and the detection probe 3 is clamped and fixed by the clamp 41 to fix the position of the detection probe 3 so that the detection probe 3 is aligned with the detection position.
[0033] The outer wall of the support cylinder 2 is slidably connected to the internal thread ring 46. A chute is provided on the outer wall of the support cylinder 2, and the chute is parallel to the axis line of the support cylinder 2. The internal thread ring 46 slides in the chute. The chute guides the internal thread ring 46 to prevent it from rotating.
[0034] As Figure 3 and 4 shown, a docking assembly is provided on the inner wall of the internal thread ring 46. The docking assembly includes a docking ring 44 and an external thread ring 45. Both the docking ring 44 and the external thread ring 45 adopt a circular ring structure. The docking ring 44 and the external thread ring 45 are fixedly connected by an arc plate. The external thread ring 45 rotates at the end of the support cylinder 2. The end of the docking ring 44 contacts the rotating part of the bearing, and the outer wall of the external thread ring 45 is threadedly connected to the internal thread ring 46. When the bearing is running, the bearing drives the external thread ring 45 to rotate by using the docking ring 44, and the external thread ring 45 makes the internal thread ring 46 slide along the support cylinder 2.
[0035] As Figure 3 shown, a positioning plate 47 is fixedly installed on the side of the internal thread ring 46. The end of the positioning plate 47 contacts the guide rod 42. The positioning plate 47 slides up and down on the outer arc surface of the support cylinder 2. A plurality of card slots 43 are provided at the top of the guide rod 42. The bottom of the positioning plate 47 is clamped with the card slots 43. The card slots 43 are clamped with the positioning plate 47 to fix the position of the guide rod 42, so as to fix the position of the clamp 41 and thus fix the position of the detection probe 3. When the positioning plate 47 contacts the guide rod 42, the external thread ring 45 disengages from the internal thread inside the internal thread ring 46, and the end of the external thread ring 45 abuts against the thread to support the position of the internal thread ring 46.
[0036] In this embodiment, when the bearing is running, the rotation of the bearing causes the docking ring 44 to rotate, and the external threaded ring 45 and the internal threaded ring 46 cooperate to convert the rotational force into pressure of the positioning plate 47 on the guide rod 42 to fix the position of the clamp 41. That is, when the bearing rotates, pressure is applied to the clamp 41 to position it, thereby avoiding vibration that may cause looseness between the clamp 41 and the detection probe 3, resulting in a displacement of the detection position of the detection probe 3.
[0037] Example 2
[0038] Based on Example 1, this example proposes a bearing temperature detection probe connection structure, such as Figure 2 As shown, the clamp 41 includes a bending plate 411 and a spring sheet 413. The bending plate 411 adopts a U-shaped structure, and the spring sheet 413 is fixedly installed at the opening of the bending plate 411. The side of the spring sheet 413 is in contact with the detection probe 3. The side of the bending plate 411 away from the spring sheet 413 is fixedly connected to the guide rod 42. The spring sheet 413 and the bending plate 411 form a U-shaped structure, and the spring sheet 413 is initially in a straight state.
[0039] The spring sheet 413 contacts the detection probe 3 to generate deformation, and the spring sheet 413 adapts to the outer curvature of the detection probe 3 to improve the fixing effect of the clamp 41 on the detection probe 3 as a whole, so as to adapt to detection probes 3 of different sizes.
[0040] A yielding spring 412 is elastically connected between the bending plate 411 and the support tube 2, and the yielding spring 412 is sleeved on the rod body of the guide rod 42. The yielding spring 412 uses elastic force to make the bending plate 411 and the spring sheet 413 yield to the detection probe 3.
[0041] In this embodiment, the spring sheet 413 contacts the detection probe 3 to generate deformation, and the spring sheet 413 adapts to the external curvature of the detection probe 3 to increase the contact area between the spring sheet 413 and the detection probe 3 and improve stability. At the same time, the yield spring 412 uses elastic force to make the bending plate 411 and the spring sheet 413 give way to the detection probe 3 to adapt to the size of the detection probe 3.
[0042] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
