DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-7 The utility model provides a technical solution: an ink scraper assembly of a printing press, comprising a mounting plate 1, a mounting shaft 2, a mounting groove 3, an ink scraper body 4, a positioning plate 5, a fixing pin 6, a fixing groove 7, a connecting groove 8, a fixed mounting column 9, a spring 10, a locking mechanism 11, a movable plate 12, a protrusion 13, an auxiliary rod 14 and a fixing sleeve 15.

[0032] When using the ink scraper assembly of the printing press, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the mounting plate 1 is connected to the mounting shaft 2, and a mounting groove 3 is opened at the lower end of the mounting plate 1, and a positioning plate 5 is fixedly connected to the upper end of the ink scraper body 4, and a fixing pin 6 is fixedly connected to the upper end of the positioning plate 5. During installation, the positioning plate 5 is first inserted into the mounting groove 3, and at the same time, the positioning plate 5 drives the fixing pin 6 to be inserted into the fixing groove 7, so that the ink scraper body 4 and the mounting groove 3 can be installed and positioned very quickly and conveniently. At the same time, the left and right sides of the lower end of the mounting plate 1 are slidably connected with fixed mounting columns 9, and the outer surface of the fixed mounting column 9 is sleeved with a spring 10, and the side of the positioning plate 5 fits with the side of the fixed mounting column 9.

[0033] Combination Figure 5 , Figure 6 and Figure 7 As shown, a locking mechanism 11 is provided on the outer side of the fixed installation column 9, and the locking mechanism 11 includes a movable plate 12 for connection, a protrusion 13 for support and connection, an auxiliary rod 14 fixedly connected to the outer side of the installation plate 1 and a fixed sleeve 15 with a limiting function. When the positioning plate 5 is inserted into the installation groove 3, the positioning plate 5 squeezes the fixed installation column 9, so that the fixed installation column 9 slides with the installation plate 1, and the fixed installation column 9 drives the movable plate 12 to slide with the protrusion 13, and the movable plate 12 slides with the auxiliary rod 14, so as to improve the stability of the fixed installation column 9 during the extension and retraction process, and the fixed installation column 9 squeezes the spring 10, so that the spring 10 undergoes elastic deformation;

[0034] When the positioning plate 5 is fully inserted into the mounting groove 3, the spring 10 restores its elastic deformation, driving the fixed mounting post 9 to slide with the mounting plate 1, so that the fixed mounting post 9 is automatically inserted into the connecting groove 8, thereby automatically installing and positioning the ink scraper body 4 and the mounting plate 1. The structural design is relatively simple, and the installation operation is very convenient, and there is no need to use bolts to achieve disassembly and assembly. In addition, after the installation and positioning between the ink scraper body 4 and the mounting plate 1 is completed, the fixing sleeve 15 is aligned with the auxiliary rod 14, and the fixing sleeve 15 is rotated by hand or by an external wrench. The fixing sleeve 15 and the auxiliary rod 14 are threadedly connected, so that the fixing sleeve 15 fits the outer side surface of the upper end of the movable plate 12, thereby facilitating locking between the movable plate 12 and the auxiliary rod 14, realizing the limitation between the fixed mounting post 9 and the mounting plate 1, thereby preventing the fixed mounting post 9 from loosening from the connecting groove 8, and improving the tightness of the installation between the ink scraper body 4 and the mounting plate 1.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
