Description

Technical Field

[0002] Currently, as a key transmission component in mechanical equipment, the operating status of gearboxes directly affects the reliability and lifespan of the overall equipment, and temperature monitoring is one of the important indicators for evaluating the working status of gearboxes.

[0003] Traditional gearbox temperature detection mainly uses contact thermometers or fixed infrared thermometers, which suffer from poor detection flexibility and difficulty in adapting to complex internal structures. Especially in situations with limited space or requiring multi-angle detection, the temperature probes of existing equipment often cannot be effectively aligned with the target area, resulting in incomplete detection data or inconvenient operation.

[0004] To address the aforementioned issues, this patent proposes a gearbox-specific temperature tester that enables high-precision multi-directional adjustment, features automatic reset, and is easy to operate. This solves problems such as numerous blind spots in detection, inaccurate directional control, and poor mechanism stability in existing technologies, thereby meeting the industrial demand for efficient and accurate gearbox temperature detection. Utility Model Content

[0005] The main purpose of this invention is to propose a temperature tester for gearbox testing, which aims to solve the problems of traditional gearbox temperature testing using fixed-installation infrared temperature measuring devices, which have poor testing flexibility and are difficult to test complex internal structures.

[0006] To address the aforementioned problems, this utility model proposes a temperature tester for gearbox testing, comprising a testing main unit, a switch button located on the lower rear side of the testing main unit, a hand handle connected to the front lower end of the testing main unit, a display screen located at the intersection of the upper end and the front end of the testing main unit, with the switch button located below the display screen, a testing button located on the upper rear side of the hand handle, a connecting tube connected to the center of the rear end of the testing main unit, a temperature measuring head rotatably connected to the rear end of the connecting tube, an infrared detector located inside the rear end of the temperature measuring head, and the infrared detector connected to the testing main unit via a wiring harness.

[0007] Preferably, a steering ball sleeve is connected to the outer rear end of the connecting pipe, and a steering ball head is rotatably connected to the inner rear end of the steering ball sleeve, with the steering ball head connected to the outer front end of the temperature measuring head.

[0008] Preferably, a steering pull plate is connected to the front side of the outer wall of the temperature measuring head, and the steering pull plate is located at the rear end of the steering ball head. A rope-limiting ring is connected to the outside of the steering ball head, and multiple rope-limiting holes are passed through the inside of the rope-limiting ring.

[0009] Preferably, a deflection ball head is connected to the front side of the connecting pipe, a deflection ball sleeve is sleeved on the outside of the deflection ball head, a deflection pull plate is connected to the outside of the deflection ball sleeve, and multiple deflection handles are connected to the outside of the deflection pull plate.

[0010] Preferably, a plurality of deflection ropes are connected between the steering pull plate and the deflection pull plate, and the plurality of deflection ropes pass through the interior of a plurality of rope limiting holes and are slidably connected to the plurality of rope limiting holes.

[0011] Preferably, a plurality of arc-shaped limiting slide tubes and limiting slide rods are provided on the front side between the connecting tube and the deflection pull plate, and the plurality of limiting slide rods are respectively inserted into the plurality of limiting slide tubes and slidably connected with the plurality of limiting slide tubes.

[0012] Preferably, the ends of the limiting slide tube and the limiting slide rod are each connected to an adjusting ball head and an adjusting ball sleeve, and the adjusting ball sleeve is fitted over the adjusting ball head and rotatably connected to the adjusting ball head.

[0013] Preferably, the adjusting ball sleeve connected to the limiting slide tube is fixedly connected to the front side of the outer wall of the connecting tube, and the adjusting ball sleeve connected to the limiting slide rod is fixedly connected to the inner side of the front end of the deflection pull plate.

[0014] Beneficial effects:

[0015] 1.

[0016] 2. This utility model adopts a linkage structure of deflection pull plate, deflection pull rope and rope limiting ring.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To achieve the above-mentioned utility model objectives, such as Figures 1-5As shown, this utility model provides a temperature tester for gearbox testing, including a main unit 1. A switch button is located on the lower rear side of the main unit 1. A hand handle 2 is connected to the front lower end of the main unit 1. A display screen 3 is located at the intersection of the upper end and the front end of the main unit 1, with the switch button located below the display screen 3. A test button 4 is located on the upper rear side of the hand handle 2. A connecting tube 6 is connected to the center of the rear end of the main unit 1. A temperature measuring head 5 is rotatably connected to the rear end of the connecting tube 6. An infrared detector is located inside the rear end of the temperature measuring head 5, and the infrared detector is connected to the main unit 1 via a wiring harness. During the temperature testing of the gearbox, the temperature tester is operated by hand... The handle 2 is held in the hand, and the power is turned on and off using the power button. The infrared detector inside the rear end of the temperature measuring head 5 detects the temperature of the gearbox. The infrared detector can be turned on by pressing the detection button 4, and the temperature at the detection point can be displayed on the display screen 3. Since the temperature measuring head 5 is rotatably connected to the rear end of the connecting tube 6, and the infrared detector is installed inside the rear end of the temperature measuring head 5, the detection direction of the infrared detector can be controlled by rotating the rear end of the connecting tube 6. This allows the infrared detector to rotate at multiple angles, making it easier for the infrared detector to reach hard-to-detect positions in the gearbox, thus improving the ease of use of the temperature detector.

[0029] Preferably, a steering ball sleeve 7 is connected to the outer rear end of the connecting pipe 6, and a steering ball head 8 is rotatably connected to the inner rear end of the steering ball sleeve 7. The steering ball head 8 is connected to the outer front end of the temperature measuring head 5. The temperature measuring head 5 can be connected to the connecting pipe 6 through the steering ball sleeve 7 and the steering ball head 8, and the detection direction of the infrared detector head can be controlled by the rotation of the steering ball head 8 inside the steering ball sleeve 7, so that the temperature measuring head 5 can rotate at multiple angles.

[0030] Preferably, a steering pull plate 9 is connected to the front side of the outer wall of the temperature measuring head 5, and the steering pull plate 9 is located at the rear end of the steering ball head 8. A rope limiting ring 10 is connected to the outside of the steering ball head 8. Multiple rope limiting holes 11 pass through the inside of the rope limiting ring 10. A deflection ball head 12 is connected to the front side of the outside of the connecting pipe 6. A deflection ball sleeve 13 is sleeved on the outside of the deflection ball head 12. A deflection pull plate 14 is connected to the outside of the deflection ball sleeve 13. Multiple deflection handles 15 are connected to the outside of the deflection pull plate 14. Multiple deflection pull ropes 16 are connected between the steering pull plate 9 and the deflection pull plate 14. The multiple deflection pull ropes 16 pass through the multiple rope limiting holes 11 and are slidably connected to the multiple rope limiting holes 11. In the process of controlling the detection direction of the temperature measuring head 5, pulling the deflection handle 15 in the corresponding direction forward deflects the head. Handle 15 drives the deflection ball sleeve 13 and deflection pull plate 14 to deflect in the corresponding direction. The deflection ball sleeve 13 slides outside the deflection ball head 12, causing the deflection pull plate 14 to deflect forward around the center of the deflection ball head 12. At the same time, the deflection ball head 12 and deflection ball sleeve 13 restrict the position between the deflection pull plate 14 and the connecting pipe 6. At this time, the deflection pull plate 14 pulls the deflection pull rope 16 in the corresponding direction forward. The deflection pull rope 16 slides forward inside the corresponding rope limiting hole 11 and pulls the steering pull plate 9 forward. The steering pull plate 9 drives the steering ball head 8 to deflect in the corresponding direction inside the steering ball sleeve 7 through the temperature measuring head 5, so that the temperature measuring head 5 will deflect in the corresponding direction around the center of the steering ball sleeve 7 and the steering ball head 8, thereby controlling the detection direction of the temperature measuring head 5.

[0031] Preferably, a plurality of arc-shaped limiting slide tubes 17 and limiting slide rods 18 are provided on the front side between the connecting pipe 6 and the deflection pull plate 14. The plurality of limiting slide rods 18 are respectively inserted into the plurality of limiting slide tubes 17 and are slidably connected to the plurality of limiting slide tubes 17. The far ends of the limiting slide tubes 17 and the limiting slide rods 18 are each connected to an adjusting ball head 19 and an adjusting ball sleeve 20. The adjusting ball sleeve 20 is sleeved on the outside of the adjusting ball head 19 and is rotatably connected to the adjusting ball head 19. The adjusting ball sleeve 20 connected to the limiting slide tube 17 is fixedly connected to the front side of the outer wall of the connecting pipe 6. The adjusting ball sleeve 20 connected to the limiting slide rod 18 is fixedly connected to the inner side of the front end of the deflection pull plate 14. A return spring 21 is provided at the front end of the limiting slide rod 18. Located inside the limiting slide tube 17, when the deflection pull plate 14 deflects in the corresponding direction, the deflection pull plate 14 can drive the limiting slide rod 18 to slide inside the limiting slide tube 17 through the adjusting ball head 19 and adjusting ball sleeve 20, and compress the return spring 21. The limiting slide tube 17 and the limiting slide rod 18 can both adjust their positions relative to the connecting tube 6 and the deflection pull plate 14 by rotating the adjusting ball head 19 inside the adjusting ball sleeve 20, ensuring that the deflection pull plate 14 can deflect smoothly. At the same time, the limiting slide tube 17 and the limiting slide rod 18 restrict the deflection pull plate 14 from rotating around the central axis of the connecting tube 6, so that the deflection pull plate 14 can only deflect forward and backward, and cannot rotate left and right, preventing multiple deflection pull ropes 16 from getting tangled together.

[0032] Furthermore, when the temperature detection is completed, the deflection handle 15 is released, and the deflection pull plate 14 loses the pull of the deflection handle 15. At this time, the limit slide rod 18 in the corresponding direction slides backward inside the limit slide tube 17 under the elastic force of the return spring 21, and drives the deflection pull plate 14 back to the position perpendicular to the connecting tube 6, so that the temperature measuring head 5 returns to its original position. When the deflection pull plate 14 returns to its original position, the deflection pull plate 14 is stably in a state perpendicular to the connecting tube 6 under the combined action of multiple limit slide rods 18 and multiple return springs 21, ensuring that the temperature measuring head 5 is stably in its original position for the next detection.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
