Fig. 1 to Fig. 8 is please referred to, the plate cylinder 10 provided in an embodiment of the utility model includes barrel 20, print Version 30, the tight block 40 of branch, pressure spring 50 and fixing bolt 60.

Wherein, barrel 20 is substantially cylindrical, and the both ends of barrel 20, which are respectively equipped with, stretches out in the convex of its outer wall Platform 21, wherein offer a crack 22 for extending to two boss 21 on barrel 20, and be located at crack 22 on its barrel 20 Side be respectively equipped with symmetrically arranged two containers 23, wherein each container 23 is respectively arranged on close to corresponding convex The position of platform 21, wherein the inner wall that each container 23 is located at 22 side of crack is respectively equipped with one for accommodating the accommodating of pressure spring 50 Notch 24, and its container 23 and accommodating notch 24 are located at the left and right sides of crack 22.Wherein each container 23 is separate The inner wall of 22 side of crack is equipped with the fixed hole 25 through its barrel 20, is equipped in fixed hole 25 and fixing bolt 60 screw threads to match, wherein the accommodating notch 24 and fixed hole 25 are provided close to the bottom of the container 23, wherein should Barrel 20 be fixed through-hole 25 perforative side be equipped with one accommodate the fixed hole 25 evacuation notch 26.

Wherein, printing plate 30 includes a main part 31 and bends two extensions 32 of extension set on 31 both ends of main part, In, which is substantially bent into cylindrical shape, and there are certain gap between main part 31, two of them extension 32 is mutual Extend in parallel and along the internal bend of main part 31, and shape has angle two extensions 32 mutually between main part 31, In, it is preferred that in the present embodiment, 120 ° of angles, another extension 32 and master are formed between one extension 32 and main part 31 60 ° of angles are formed between body portion 31.Wherein the diameter of printing plate 30 is slightly larger than the diameter of barrel 20, so that when printing plate 30 is installed Its main part 31 is pasted on barrel 20；Thickness between two extensions 32 of the printing plate 30 is less than the thickness of crack 22, It should also be noted that there is also an angles between the crack 22 and barrel 20, so that it extends when printing plate 30 is installed Portion 32 is parallel with crack 22, and is placed in crack 22；Two evacuation that the length of the printing plate 30 is less than barrel 20 simultaneously lack The distance between mouth 26 avoids when so that the printing plate 30 installation being pasted on barrel 20 due to covering to evacuation notch 26 The problem of lid causes user that can not adjust fixing bolt 60.By being in the crack 22 of angle with it in the setting of barrel 20, and prolong Between extending portion 32 and main part 31 be in an angle so that when its printing plate 30 is attached on barrel 20 stable connection be not easy to fall it is de- From.

Wherein, it props up tight block 40 to be placed in the container 23 of the barrel 20, the section for propping up tight block 40 is substantially rectangular Trapezoidal, right-angle side is placed in the inner wall of container 23, and bevel edge is set to the top of container 23, and wherein the tight block 40 of the branch holds When being placed in the container 23, the thickness for propping up tight block 40 is less than the thickness of container 23, so that it, which props up tight block 40, to accommodate It is moved freely in slot 23, and the gap between the tight block 40 of the branch and container 23 is greater than the thickness of two extensions 32, so that When the printing plate 30 and the tight block 40 of branch are placed in the container 23, propping up tight block 40 can also move freely in container 23.

Wherein, pressure spring 50 is placed in the accommodating notch 24, and the length of pressure spring 50 is greater than the length of the accommodating notch 24, The accommodating notch 24 is located at the bottom end of the container 23 simultaneously, and top of the top of the accommodating notch 24 away from container 23 away from From the length for being greater than the extension 32, when so that the printing plate 30 being placed in container 23, extension 32 and container 23 Top also has a certain distance, avoids leading to its pressure since extension 32 is too long or accommodating notch 24 is set to too high position Spring 50 and extension 32 it is inconsistent and can not be inconsistent with tight block 40 is propped up problem.

Wherein, the fixing bolt 60 is by spinning in and out, so that can be placed in the fixed hole 25, and the fixing bolt 60 length is greater than the length of fixed hole 25, so that its end can be placed in container when the fixing bolt 60 is fully screwed into In 23.Wherein, which can be used for realizing evacuation when user carries out turn-knob to fixing bolt 60.

In use, its by pressure spring 50, the tight block 40 of branch and fixing bolt 60 be respectively charged into accommodating notch 24, container 23 and In solid through-hole, further, printing plate 30 is inserted in the outer wall of barrel 20, and the extension 32 of its printing plate 30 and crack 22 In parallel, it while being placed in the crack 22, and two extensions 32 are clipped between 23 inner wall of container and the tight block 40 of branch, are used at this time Family is by slowly screwing the fixing bolt 60, so that its fixing bolt 60 is inconsistent with the tight block 40 of branch and pushes the tight block 40 of branch forward It is mobile, extension 32 is compressed slowly with the tight block 40 of realization branch and inconsistent wait a moment of extension 32 of printing plate 30, at this time the extension 32 Be clamped between the inner wall and the tight block 40 of branch of container 23 respectively so that realize the fixation of printing plate 30, while pressure spring 50 due to By the mobile conflict for propping up tight block 40, so that generating elastic deformation；When user needs to change the printing plate 30, user is by unscrewing The fixing bolt 60, so that fixing bolt 60 is separated with tight 40 phase of block is propped up, pressure spring 50 is not due to by fixing bolt 60 Extruding force, so that pressure spring 50 restores elastic deformation, and pushes the tight block 40 of branch mobile, so that it props up tight block 40 and 32 phase of extension point From taking out the printing plate 30 convenient for user and replace.

The utility model embodiment also provides a kind of flexible printing press, which includes the plate cylinder in above-described embodiment.

Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed, But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to In the protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
