Description

Technical Field

[0001] This utility model relates to the field of oil flow observation technology, and in particular to an oil flow observation mirror. Background Technology

[0002] In the oil circuit system of industrial equipment, the oil flow sight glass is a key component for operators to judge the oil flow status and the degree of contamination. Operators can directly observe the inside from the outside. However, impurities such as colloids and metal particles in the oil will gradually adhere to the surface of the sight glass, forming a dense layer of dirt, which will blur the field of view and affect the judgment of the equipment status. Therefore, it is crucial to clean the surface of the sight glass.

[0003] Currently, there are observation scopes on the market with scrapers. By turning the external handle, the internal scraper is moved to scrape the surface of the observation scope, thereby scraping off the layer of dirt attached to the surface of the observation scope. However, the scraper is generally made of corrosion-resistant flexible material. As the usage time is extended, a dense layer of dirt will also be attached to the surface of the scraper. When using a scraper with a layer of dirt attached, it will not only fail to effectively remove the dirt from the surface of the observation scope, but may also bring the dirt from the scraper surface to the surface of the observation scope, making the field of view of the observation scope even more blurred.

[0004] Therefore, based on the above situation, it is necessary to design an oil flow observation mirror to solve the above problems. Utility Model Content

[0005] This invention provides an oil flow observation mirror to solve the problems in the prior art.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] An oil flow observation mirror includes an observation mirror body and a scraper for cleaning the lens on the observation mirror body. It also includes an extension, an operating component, and an adjusting component. The extension is located in the middle of the lens and extends into the interior of the observation mirror body. The operating component is sealed and movably connected to the interior of the extension. One end of the operating component extending into the observation mirror body is connected to the scraper via a rotating shaft. The adjusting component is located within the operating component to adjust the scraper to a state where its axis coincides with the axis of the operating component. The cleaning component is located on the extension. When the scraper and the operating component's axis coincide, pulling the operating component and the scraper cleans the dirt from the surface of the scraper.

[0008] Preferably, the adjusting component includes a worm gear rotatably connected to one end of the operating component extending into the interior of the observation mirror body, a worm wheel meshing with the worm gear, and an adjusting rod connected to the worm gear. The adjusting rod passes through the operating component and is rotatably and sealed to the operating component. The worm wheel is disposed on a rotating shaft and connected to the scraper component.

[0009] Preferably, the operating component is provided with a handle corresponding to the position of the cleaning section, and the lens is provided with a marking section. When the handle and the marking section are aligned, the scraper component, which is aligned with the axis of the operating component, can smoothly pass through the central channel of the cleaning section.

[0010] Preferably, the cleaning section is provided with a flared section, the inner diameter of which gradually increases along the passing direction of the scraper to form a flared transition section.

[0011] Preferably, the operating element includes an operating lever and an elastic portion wrapped around the operating lever.

[0012] Preferably, the scraper includes a connecting rod and a scraping part detachably mounted on the connecting rod.

[0013] The beneficial effects of this utility model are as follows: by rotating the operating component, the scraper component is driven to rotate, thereby cleaning the dirt on the surface of the lens. When it is necessary to clean the surface of the scraper component, the scraper component and the operating component are aligned by adjusting the adjusting component, and the two are pulled out of the observation lens body and come into contact with the cleaning part to scrape off the dirt on the surface of the scraper component, thereby cleaning the scraper component and solving the problem of secondary pollution of the lens surface by the scraper component.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0023] Reference Figures 1-6 As shown, an oil flow observation mirror includes an observation mirror body 1, which can be connected to an oil circuit system via threads, flanges, or other connection methods. Figure 1 The diagram shown is a cross-sectional view of the prior art. A scraper 2 is installed inside the observation lens body 1 to clean the lens 11. To facilitate cleaning the scraper 2 and reduce secondary contamination of the lens 11, an extension 3 is provided in the middle of the lens 11. One end of the extension 3 extends into the interior of the observation lens body 1. An operating component 4 is sealed and movably connected inside the extension 3. One end of the operating component 4 extending into the interior of the observation lens body 1 is connected to the scraper 2 via a rotating shaft 7. This sealed and movable connection prevents oil leakage during the movement of the operating component 4 within the extension 3, ensuring that the seal between the two is unaffected by the movement. A pre-tightening force keeps the seal in close contact with the moving surface. Even if the components move relative to each other, the seal moves synchronously with the contact surface, continuously blocking the gap. This is prior art and will not be elaborated further here.

[0024] By rotating the operating component 4, the scraper component 2 rotates along the center of the lens 11 to scrape away dirt from the surface of the lens 11. When it is necessary to scrape away dirt from the surface of the scraper component 2, the adjusting component 5 located inside the operating component 4 is operated to adjust the scraper component 2 to a state where it coincides with the axis of the operating component 4. At this time, the scraper component 2 and the operating component 4 form a straight line. By pulling the operating component 4, the scraper component 2 is moved to the outside of the observation lens body 1. In order to scrape away dirt from the surface of the scraper component 2, a cleaning part 6 is provided on the extension part 3. As the scraper component 2 is pulled outward, various parts of the scraper component 2 continuously come into contact with the cleaning part 6, thereby cleaning the dirt from the surface of the scraper component 2. In the above operation, dirt from the surface of the lens 11 can be scraped away at the same time as dirt from the surface of the scraper component 2, reducing the problem of secondary contamination of the lens 11 caused by dirt accumulation on the scraper component 2.

[0025] Reference Figure 4 As shown, the adjusting member 5 further includes a worm gear 52 rotatably connected to one end of the operating member 4 extending into the observation mirror body 1, a worm wheel 51 meshing with the worm gear 52, and an adjusting rod 53 connected to the worm gear 52. When it is necessary to clean the surface of the scraper member 2, the scraper member 2 on the surface of the lens 11 needs to be aligned with the axis of the operating member 4. At this time, by rotating the adjusting rod 53 which passes through the operating member 4 and is rotatably connected to the operating member 4, the adjusting rod 53 drives the worm gear 52 to rotate. At the same time, the worm gear 52 rotates and drives the worm wheel 51 to rotate. The worm wheel 51, being located on the rotating shaft 7 and connected to the scraper member 2, drives the scraper member 2 to rotate, thereby making the scraper member 2 and the operating member 4 align.

[0026] Reference Figure 4 As shown, the operating component 4 further includes an operating rod 41 and an elastic part 42 wrapped around the operating rod 41. The elastic part 42 can be made of materials such as rubber or silicone. At this time, the operating component 4 is similar to the piston structure in a syringe. By pulling the operating rod 41 and the elastic part 42, the scraper component 2 is moved to the outside of the observation mirror body 1, which further enhances the sealing effect on the oil.

[0027] Reference Figures 5-6As shown, further, as the scraper 2 is continuously pulled outward, the scraper 2 will come into contact with the cleaning part 6. The cleaning part 6 can be two plates or a "U"-shaped structure set on the extension part 3, and relatively thin blades are set on the two opposite surfaces. In order to ensure that the scraper 2 can accurately enter the interior of the cleaning part 6, a handle 8 corresponding to the position of the cleaning part 6 is provided on the operating part 4. The convenience of operation can be improved when rotating the operating part 4 and pulling the operating part 4. At the same time, an marking part 9 is provided on the lens 11. The marking part can be marked with arrows, colors, etc. When the positions of the handle 8 and the marking part 9 coincide, the scraper 2 can smoothly pass through the central channel of the cleaning part 6, and the thinner blades on the cleaning part 6 effectively scrape the surface of the scraper 2.

[0028] The cleaning section 6 is provided with a flared section 10. The inner diameter of the flared section 10 gradually increases along the through-path of the scraper 2, forming a flared transition section. With the setting of the flared section 10, even if the operator makes a deviation in the position judgment based on the handle 8 and the marking section 9, the scraper 2 can still move smoothly downward along the inner wall of the flared section 10 when it comes into contact with the inner wall, so as to achieve the scraping of the surface of the scraper 2 by the cleaning section 6.

[0029] Reference Figure 3 , Figure 4 As shown, the scraper component 2 further includes a connecting rod 21 and a scraping part 22 detachably mounted on the connecting rod 21. The scraping part 22 can be made of anti-corrosion rubber or other materials and can be detachably connected to the connecting rod 21 by means of screw fixing, snap-fit, etc., which facilitates the inspection and replacement of the scraping part 22.
