[0004] Some existing instruments for testing lubricating oil in hydraulic lubrication systems require testing the sealing of connections after prolonged use to prevent lubricating oil leakage. However, most existing methods for detecting lubricating oil leakage rely on visual inspection, which has low efficiency and accuracy, affecting the detection efficiency of lubricating oil leakage at the connection points of lubricating oil testing instruments. Summary of the Invention

[0005] The main purpose of this utility model is to provide a hydraulic lubrication system tester, which aims to solve the problem that some existing instruments for testing lubricating oil in hydraulic lubrication systems need to be tested for the sealing condition of the connection after long-term use to prevent lubricating oil leakage. However, most existing methods for detecting lubricating oil leakage are visual inspection methods, which have low efficiency and accuracy in detecting lubricating oil leakage, thus affecting the efficiency of lubricating oil leakage detection at the connection of the lubricating oil testing instrument.

[0006] To achieve the above objectives, the hydraulic lubrication system tester proposed in this utility model includes an oil particle size tester body, two connection ports, a touch screen and a connecting cable. A fixing frame is provided on the surface of the oil particle size tester body, a protective plate is provided on the front side of the oil particle size tester body, and a test mechanism is provided on the top and bottom of the oil particle size tester body.

[0007] The detection mechanism includes a viewing glass, a fluorescent test strip, a fixing ring, and two sliding frames. The viewing glass is embedded inside the fixing ring, the fluorescent test strip is pasted on the inner wall of the fixing ring, and the two sliding frames are fixedly connected to both sides of the fixing ring. The surface of the fluorescent test strip is in contact with the surface of the connection port.

[0008] Preferably, limit rods are fixedly connected to both sides of the top and bottom of the oil particle size analyzer body, and the sliding frame is slidably connected to the surface of the limit rods.

[0009] Preferably, limit buttons are provided on opposite sides of the two slide frames. The side of the limit button closer to the slide frame passes through the slide frame and is in close contact with the surface of the limit rod. The surface of the limit button is threadedly connected to the inner wall of the slide frame.

[0010] Preferably, the front sides of the fixed frame are fixedly connected with support blocks, the protective plate is rotatably connected between one side of the two support blocks, there is damping at the rotatable connection between the protective plate and the support blocks, and a pull block is fixedly connected to the bottom of the protective plate.

[0011] Preferably, soft pads are fixedly connected to both sides of the bottom rear side of the protective plate, and the rear side of the soft pads is in contact with the front side of the oil particle size analyzer body.

[0012] Preferably, connecting blocks are fixedly connected to both sides of the bottom of the fixed frame, and locking frames are fixedly connected to both sides of the oil particle size analyzer body. The surface of the connecting block is in contact with the inner wall of the locking frame. Screws are provided on opposite sides of the two locking frames. The side of the screws closest to the locking frame passes through the locking frame and is connected to the internal thread of the connecting block.

[0013] Preferably, mounting brackets are fixedly connected to both sides of the rear side of the fixing frame.

[0014] Preferably, the protective plate is made of impact-resistant engineering plastic.

[0015] In this utility model's technical solution, the oil particle size analyzer body is connected to the fixed frame by connecting blocks on both sides of the bottom and locking brackets on both sides of the fixed frame, and then fixed with screws. By using external bolts passing through the mounting bracket on the rear side of the fixed frame, the oil particle size analyzer body can be installed in a suitable position. The protective plate is rotatably connected to the front side of the fixed frame via a support block, and there is damping at the rotatable connection. A pull block is fixed to the bottom of the protective plate for easy operation. When the protective plate is closed, the soft pad at the bottom rear contacts the front side of the oil particle size analyzer body, providing cushioning and protection. The protective plate is made of impact-resistant engineering plastic, effectively protecting the touchscreen of the oil particle size analyzer body. The fixing ring can be adjusted by sliding the sliding frame on the limit rod to the position of the connection port. This adjustment prevents the fixing ring from interfering with the connection operation between the connection port and the external lubricating oil pipeline. The limit button ensures tight contact with the limit rod surface, fixing the position of the retaining ring through friction. Simultaneously, it brings the surface of the fluorescent test paper in the detection mechanism into contact with the surface of the connection port. If there is lubricating oil leakage at the connection port, the leaked lubricating oil will adhere to the fluorescent test paper. Under ultraviolet light, the lubricating oil on the test paper will fluoresce. The operator can observe the changes in the fluorescent test paper by illuminating it with ultraviolet light through the viewing glass, thus determining whether there is lubricating oil leakage at the connection port. This method is convenient and quick, improving the efficiency of detecting lubricating oil leakage at the connection port of the oil particle size analyzer. It also solves the problem that existing instruments for detecting lubricating oil in hydraulic lubrication systems require testing the sealing of the connection port after prolonged use to prevent lubricating oil leakage. Currently, most methods for detecting lubricating oil leakage rely on visual inspection, resulting in low efficiency and accuracy, thus affecting the efficiency of detecting lubricating oil leakage at the connection port of the lubricating oil detection instrument.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0028] This utility model provides a hydraulic lubrication system tester, which aims to solve the problem that some existing instruments for testing lubricating oil in hydraulic lubrication systems need to be tested for the sealing of the connection after long-term use to prevent lubricating oil leakage. However, most existing methods for detecting lubricating oil leakage are visual inspection, which has low efficiency and accuracy, affecting the efficiency of lubricating oil leakage detection at the connection of the lubricating oil testing instrument.

[0029] like Figure 1-5 As shown, the hydraulic lubrication system tester provided in this embodiment of the present invention includes an oil particle size tester body 1, two connection ports 7, a touch screen 8 and a connection line 9. A fixing frame 5 is provided on the surface of the oil particle size tester body 1, a protective plate 11 is provided on the front side of the oil particle size tester body 1, and a test mechanism 2 is provided on the top and bottom of the oil particle size tester body 1.

[0030] The testing mechanism 2 includes a visible glass 201, a fluorescent test paper 202, a fixing ring 203, and two sliding frames 204. The visible glass 201 is embedded inside the fixing ring 203, the fluorescent test paper 202 is pasted on the inner wall of the fixing ring 203, and the two sliding frames 204 are fixedly connected to both sides of the fixing ring 203 respectively. The surface of the fluorescent test paper 202 is in contact with the surface of the connection port 7.

[0031] In this utility model's technical solution, the oil particle size analyzer body 1 is connected to the fixed frame 5 by the connecting blocks 10 on both sides of the bottom of the fixed frame 5, which cooperate with the locking brackets 15 on both sides of the oil particle size analyzer body 1 and are fixed with screws 16. By using external bolts to pass through the mounting bracket 4 on the rear side of the fixed frame 5, the oil particle size analyzer body 1 can be installed in a suitable position. The protective plate 11 is rotatably connected to the front side of the fixed frame 5 by the support block 13, and there is damping at the rotatable connection. A pull block 6 is fixed at the bottom of the protective plate 11 for the convenience of the operator. Pulling the protective plate 11 closes the instrument, causing the soft pad 12 at the bottom rear to contact the front of the oil particle size analyzer body 1, providing cushioning and protection. The protective plate 11 is made of impact-resistant engineering plastic, effectively protecting the touchscreen 8 of the oil particle size analyzer body 1. It is also lightweight and will not deform over extended use. The fixing ring 203 can be adjusted by sliding the sliding frame 204 on the limiting rod 3 to the position of the connection port 7. This adjustment prevents the fixing ring 203 from interfering with the connection port 7. The connection to the external lubricating oil pipeline is achieved by rotating the limit button 14 to ensure tight contact with the surface of the limit rod 3. Friction then fixes the position of the retaining ring 203, simultaneously bringing the surface of the fluorescent test paper 202 in the detection mechanism 2 into contact with the surface of the connection port 7. If there is lubricating oil leakage at the connection port 7, the leaked lubricating oil will adhere to the fluorescent test paper 202. Under ultraviolet light, the lubricating oil on the fluorescent test paper 202 will fluoresce. The operator can then observe the fluorescent test paper 202 by illuminating it with an ultraviolet light through the viewing glass 201. The changes in the flow of fluid particles are used to determine whether there is lubricating oil leakage at connection port 7. This method is convenient and quick, improving the efficiency of detecting lubricating oil leakage at connection port 7 of the oil particle size analyzer body 1. It solves the problem that some existing instruments for detecting lubricating oil in hydraulic lubrication systems need to check the sealing of the connection after long-term use to prevent lubricating oil leakage. However, most existing methods for detecting leaking lubricating oil are visual inspection, which has low efficiency and accuracy, affecting the efficiency of detecting lubricating oil leakage at the connection port of the lubricating oil detection instrument.

[0032] Please refer to the following: Figure 2 and Figure 4 Limiting rods 3 are fixedly connected to both sides of the top and bottom of the oil particle size analyzer body 1, and a sliding frame 204 is slidably connected to the surface of the limiting rods 3. In this embodiment, the position of the fixing ring 203 can be easily adjusted by sliding the sliding frame 204 on the surface of the limiting rods 3.

[0033] For further information, please continue to refer to [link / reference]. Figure 1 and Figure 4Each of the two sliding frames 204 has a limit button 14 on an opposite side. The side of the limit button 14 closest to the sliding frame 204 passes through the sliding frame 204 and is in close contact with the surface of the limit rod 3. The surface of the limit button 14 is threadedly connected to the inner wall of the sliding frame 204. In this embodiment, by locking the limit button 14, the limit button 14 is moved when rotated through the threaded connection inside the sliding frame 204. This moves the limit button 14 to a position where it is in close contact with the surface of the limit rod 3, increasing the friction between the limit button 14 and the limit rod 3. This limits the sliding frame 204, the fixing ring 203, and the fluorescent test paper 202 at the connection between the connection port 7 and the external lubricating oil pipe.

[0034] Please continue to refer to this. Figure 3 The front sides of the fixed frame 5 are fixedly connected to support blocks 13. The protective plate 11 is rotatably connected between the two support blocks 13 on opposite sides. There is damping at the rotatable connection between the protective plate 11 and the support blocks 13. A pull block 6 is fixedly connected to the bottom of the protective plate 11. In this embodiment, the protective plate 11 is rotatably connected between the two support blocks 13 on opposite sides, allowing the protective plate 11 to rotate. The damping at the rotatable connection between the protective plate 11 and the support blocks 13 allows the protective plate 11 to be limited to any position, facilitating the operation of the touch screen 8 after opening the protective plate 11. The protective plate 11 can be easily pulled by holding the pull block 6.

[0035] Please refer to Figure 1 and Figure 3 Both sides of the bottom rear side of the protective plate 11 are fixedly connected to soft pads 12, and the rear side of the soft pads 12 contacts the front side of the oil particle size analyzer body 1. In this embodiment, by rotating the protective plate 11 downwards until the soft pads 12 contact the front side of the oil particle size analyzer body 1, the protective plate 11 can protect the touch screen 8, and the soft pads 12 can prevent the protective plate 11 from causing wear to the oil particle size analyzer body 1.

[0036] Additionally, please refer to Figure 3 and Figure 5 The bottom of the fixed frame 5 is fixedly connected to both sides of the connecting blocks 10, and the oil particle size analyzer body 1 is fixedly connected to both sides of the locking frame 1. The surface of the connecting blocks 10 contacts the inner wall of the locking frame 15. Screws 16 are provided on opposite sides of the two locking frames 15. The side of the screws 16 closest to the locking frame 15 passes through the locking frame 15 and is connected to the internal thread of the connecting blocks 10. In this embodiment, the oil particle size analyzer body 1 is connected to the fixed frame 5 by inserting it from the bottom of the fixed frame 5 upwards until the inner wall of the locking frame 15 contacts the surface of the connecting blocks 10, and then the screws 16 pass through the locking frames 15 and are connected to the internal thread of the connecting blocks 10.

[0037] Please refer to Figure 1 and Figure 3 Mounting brackets 4 are fixedly connected to both sides of the rear side of the fixing frame 5. In this embodiment, after connecting the oil particle size analyzer body 1 to the fixing frame 5, the oil particle size analyzer body 1 can be easily and stably fixed in the required position by passing external bolts through the mounting brackets 4.

[0038] Additionally, please refer to Figure 3 The protective plate 11 is made of impact-resistant engineering plastic. In this embodiment, by using impact-resistant engineering plastic for the protective plate 11, the touch screen 8 of the oil particle size analyzer body 1 can be effectively protected, and it is also lightweight and will not deform after long-term use.

[0039] It should be noted that the main body of the oil particle size analyzer 1 is a mature technology that has already been published, and will not be described in detail here.
