Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic polishing, in particular to a portable plastic polishing device. Background Art
[0002] Plastic polishing and grinding is a common plastic processing method. It can greatly improve the texture and aesthetics of plastics, and polished and ground plastics can also increase the service life of plastics. However, when performing this treatment, it is necessary to consider the characteristics of the material and choose appropriate polishing and grinding methods and grinding fluids to obtain the best results.
[0003] In order to meet the polishing and grinding of different plastic products, various types of plastic grinders have emerged. For example, according to the way of use, they are divided into hand-held polishers and desktop polishers. The main advantage of hand-held polishers is that they are easy to carry and suitable for polishing and grinding of small areas. However, hand-held polishers have certain limitations during use, that is, the handle length is relatively short. For example, when polishing a plastic panel, polishing at a high or long distance position cannot be performed, and other auxiliary tools or staff moving positions are required to achieve this, which is very inconvenient to use. Therefore, a portable plastic polishing device is proposed. Utility Model Content

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0022] like Figures 1 to 3As shown, a portable plastic grinding device comprises a grinding head 1, on which a handle 2 is fixedly mounted, a groove 3 is provided on the side wall of the handle 2, a rotating shaft 4 is movably mounted inside the groove 3, a handle 2 5 is fixedly mounted on the side wall of the rotating shaft 4, a threaded hole 6 is provided on the top of the handle 2, a threaded groove 7 is provided on the inner bottom surface of the groove 3, a fixing hole 8 is provided on the top of the handle 2 5, a bolt 9 is threadedly connected inside the threaded hole 6, the threaded groove 7 and the fixing hole 8, a groove 2 10 is provided on the wall of the handle 2 5, a rotating shaft 2 11 is movably mounted inside the groove 2 10, a handle 3 12 is fixedly mounted on the side wall of the rotating shaft 2 11, a threaded hole 2 13 is provided on the top of the handle 2 5, a threaded groove 2 14 is provided on the inner bottom surface of the groove 2 10, a fixing hole 2 15 is provided on the top of the handle 3 12, and a bolt 2 16 is threadedly connected inside the handle 3 12, the threaded hole 2 13 and the fixing hole 2 15. Yes, if the length of handle 12 is short when the staff is grinding the plastic, they can rotate handle 2 5 to align the threaded hole 16, thread groove 17, and fixing hole 18 longitudinally, and then thread the bolt 19 into the threaded hole 16, thread groove 17, and fixing hole 18, and then continue to rotate handle 3 12 to align the threaded hole 2 13, thread groove 2 14, and fixing hole 2 15 longitudinally, and then thread the bolt 2 16 into the threaded hole 2 13, thread groove 2 14, and fixing hole 2 15. The staff can grind at a high place or a long distance by holding handle 2 5 or handle 3 12. When carrying, they only need to turn out the bolt 19 from the threaded hole 16, thread groove 17, and fixing hole 18, and turn out the bolt 2 16 from the threaded hole 13, thread groove 2 14, and fixing hole 2 15, then they can turn handle 3 12 into the inside of groove 2 10, and turn handle 2 5 into the inside of groove 3, so that it is convenient for the staff to carry.
[0023] like Figure 1 , Figure 2 As shown, the top and bottom of the handle 2 5 are inlaid with magnetic blocks 17, and the inner top and bottom of the groove 3 are inlaid with magnetic blocks 2 18. The magnetic blocks 17 and 18 are mutually attracted. It should be noted that when the handle 2 5 is rotated to the inside of the groove 13, each magnetic block 17 is attracted to the adjacent magnetic block 2 18, which can prevent the handle 2 5 from being easily rotated out of the groove 3.
[0024] like Figure 1 , Figure 2As shown, the top and bottom of the handle three 12 are inlaid with magnetic blocks three 19, and the inner top and bottom of the magnetic block four 20 are inlaid with magnetic blocks four 20. The magnetic blocks three 19 and the magnetic blocks four 20 are mutually adsorbed. It should be noted that when the handle three 12 is rotated to the inside of the groove two 10, each magnetic block three 19 is mutually adsorbed with the adjacent magnetic blocks four 20, which can prevent the handle three 12 from being easily rotated out of the groove two 10.
[0025] like Figure 2 As shown, a rectangular plate 1 21 is provided above and below the handle 2 5, and a rectangular plate 22 is provided above and below the handle 3 12. It should be noted that the rectangular plate 1 21 can make up for the horizontal plane difference between the top of the handle 2 5 and the top of the handle 1 2, as well as the horizontal plane difference between the bottom of the handle 2 5 and the bottom of the handle 1 2, and the rectangular plate 22 can make up for the horizontal plane difference between the top of the handle 3 12 and the top of the handle 1 2, as well as the horizontal plane difference between the bottom of the handle 3 12 and the bottom of the handle 1 2.
[0026] like Figures 1 to 3 As shown, the top and bottom of the handle 2 5 are provided with two convex-shaped fixing grooves 23, and a fixing rod 24 is movably installed inside each fixing groove 23. Each rectangular plate 1 21 and rectangular plate 2 22 are fixedly connected to two adjacent fixing rods 24. It should be noted that the rectangular plate 1 21 and the rectangular plate 2 22 can be installed to the top and bottom of the handle 2 5 and the handle 3 12 respectively through the cooperation of the fixing grooves 23 and the fixing rods 24.
[0027] like Figure 1 As shown, a circular groove 25 is provided at one end of the handle three 12 away from the rotating shaft two 11, and a threaded rod 26 is connected to the internal thread of the circular groove 25, and a fixing plate 27 is fixedly connected to one end of the threaded rod 26 away from the rotating shaft two 11. It should be noted that by rotating the threaded rod 26 to be installed inside the circular groove 25, the fixing plate 27 can be used to prevent the rectangular plate two 22 and the rectangular plate one 21 from respectively driving the fixed rods 24 connected to themselves to slide out of the corresponding fixing grooves 23.
[0028] In summary:
[0029] If the length of handle 1 2 is short when the staff is grinding the plastic, they can turn handle 2 5 to align the threaded hole 1 6, thread groove 1 7, and fixing hole 1 8 longitudinally, and then thread the bolt 1 9 to the inside of the threaded hole 1 6, thread groove 1 7, and fixing hole 1 8, and then continue to turn handle 3 12 to align the threaded hole 2 13, thread groove 2 14, and fixing hole 2 15 longitudinally, and then thread the bolt 2 16 to the inside of the threaded hole 2 13, thread groove 2 14, and fixing hole 2 15. The staff can grind at a high place or a long distance by holding handle 2 5 or handle 3 12. When carrying, they only need to turn out the bolt 1 9 from the inside of the threaded hole 1 6, thread groove 1 7, and fixing hole 1 8, and turn out the bolt 2 16 from the inside of the threaded hole 2 13, thread groove 2 14, and fixing hole 2 15, then the handle 3 12 can be rotated to the inside of the groove 2 10, and the handle 2 5 can be rotated to the inside of the groove 3, so that it is convenient for the staff to carry.
