[0002] During the overhaul of refining and chemical equipment, it is often necessary to scrape the sliding bearings of the equipment. However, traditional scrapers are not convenient to carry, especially triangular scrapers, which are contraband. In addition, the blade shapes of other scrapers are not convenient for use with small bearings such as sliding bearings. Therefore, it is necessary to design a scraper that is convenient to carry and use. Content of the Utility Model

[0003] The purpose of the utility model is to design a portable foldable sliding bearing scraper to make it convenient to carry and use.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A portable foldable sliding bearing scraper includes a base plate and a mating plate fixedly connected by a connecting nail. Fixed shafts are also provided on the base plate and the mating plate. A blade is rotatably connected to the fixed shafts. The blade is located between the base plate and the mating plate. A positioning block is provided between the base plate and the mating plate. When the blade abuts against the positioning block, the outer edge formed by the combination of the blade and the base plate is a circle.

[0006] Further, for the above portable foldable sliding bearing scraper, the lower ends of the base plate and the mating plate have arc-shaped notches.

[0007] Further, for the above portable foldable sliding bearing scraper, the base plate and the mating plate are provided with slot holes.

[0008] Further, for the above portable foldable sliding bearing scraper, the upper end of the base plate is provided with a semi-circular through hole, and the shape of the mating plate matches the shape of the lower end of the base plate.

[0009] Further, for the above portable foldable sliding bearing scraper, the upper end of the base plate is provided with a hanging ring.

[0010] Further, for the above portable foldable sliding bearing scraper, the diameter of the circle formed by the outer edge of the combination of the blade and the base plate is 45 mm, and the thickness of the blade is 2 mm.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: A portable foldable sliding bearing scraper provided by the present utility model forms a circle at the outer edge of the combination of the blade and the substrate when the scraper is in the retracted state, which is more convenient to carry compared to triangular scrapers. When using the scraper, the blade can be rotated away along the fixed shaft. The circular outer edge of the blade facilitates scraping on the arc-shaped inner wall of the sliding bearing, and it is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following will, in conjunction with the drawings and preferred embodiments, describe in detail the specific embodiments, structures, features, and effects of the present utility model as follows.

[0020] Embodiment: Please refer to Figures 1-4 , A portable foldable sliding bearing scraper, including a substrate 1 and a matching plate 2. The substrate 1 is a circular plate-shaped with an arc-shaped notch at the lower end and a semi-circular through hole at the upper end. The shape of the matching plate 2 matches the shape of the lower end of the substrate 1, that is, the projection overlaps and the shapes are the same. Therefore, the lower end of the matching plate 2 also has an arc-shaped notch.

[0021] There is a certain distance between the substrate 1 and the mating plate 2, which is 4 mm in this embodiment. The upper ends of the substrate 1 and the mating plate 2 are fixedly connected by connecting pins 3, and the lower ends of the substrate 1 and the mating plate 2 are fixedly connected by a fixed shaft 6. A positioning block 4 is provided between the upper ends of the substrate 1 and the mating plate 2. The positioning block 4 is fixedly connected to the substrate 1 and the mating plate 2 respectively. The positioning block 4 is used to position the blade 7 in the retracted state.

[0022] A blade 7 is rotatably connected to the fixed shaft 6. The blade 7 is located between the substrate 1 and the mating plate 2. The thickness of the blade 7 is 2 mm, and the blade 7 is cut from high-speed steel.

[0023] When the scraper is in the retracted state, the blade 7 is completely retracted between the substrate 1 and the mating plate 2 and abuts against the positioning block 4. At this time, the outer edge of the combination of the blade 7 and the substrate 1 forms a circle, and the diameter of this circle is 45 mm.

[0024] When the scraper is in the working state, the blade 7 can rotate at most to abut against the connecting pin 3, and the overall length is 65 mm. At this time, the state of the blade 7 is as Figure 3 shown. At this time, the scraper can be reversed, and the side surfaces of the substrate 1 and the mating plate 2 are held by hand to scrape the sliding bearing from bottom to top.

[0025] Furthermore, slot holes 5 are provided on the substrate 1 and the mating plate 2 to reduce the weight of the scraper.

[0026] Furthermore, a hanging ring 11 is provided at the upper end of the substrate 1, so that the scraper can be hung on a keychain and carried around.

[0027] The working principle of this embodiment: A portable foldable sliding bearing scraper provided in this embodiment. When the scraper is in the retracted state, the outer edge of the combination of the blade 7 and the substrate 1 forms a circle, which is more convenient to carry compared to a triangular scraper. When the scraper is in use, the blade 7 can be rotated away along the fixed shaft 6. The circular arc outer edge of the blade 7 is convenient for scraping on the inner arc wall of the sliding bearing, and it is easy to use.

[0028] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "upper", "lower", "left", "right", "front", "rear" and similar expressions used in this article are only for the purpose of illustration.

[0029] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to equivalent embodiments with equivalent changes within the scope of the technical solution of the present utility model by using the disclosed technical content above. However, as long as it does not depart from the content of the technical solution of the present utility model, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
