[0003] The wheels in ordinary ink fountain structures are not equipped with bearings when they rotate, resulting in a slower rotation speed, which reduces the user experience. Utility Model Content

[0004] The utility model aims to provide a hand-driven bearing ink fountain wheel to solve the above-mentioned background technical problems.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hand-driven bearing ink fountain wheel, comprising: a screw, one end of which is fixedly connected to a nut;

[0006] Bearings, the bearings are slidably mounted on the left and right sides of the outer side of the screw;

[0007] A bearing spacer sleeve, wherein the bearing spacer sleeve is slidably mounted at the middle of the outer side of the screw;

[0008] The ink fountain wheel is rotatably mounted on the outer sides of two bearings.

[0009] Preferably, baffles are fixedly connected to the front and rear sides of the ink fountain wheel, and the maximum outer diameter of the baffles is greater than the outer diameter of the middle section of the ink fountain wheel.

[0010] Preferably, positioning grooves are provided on the front and rear sides of the ink fountain wheel, and the inner diameter of the positioning grooves is matched with the outer diameter of the bearing.

[0011] Preferably, a through groove is provided between adjacent surfaces of the positioning groove, and the bearing spacer is located on the inner side of the through groove.

[0012] Preferably, a nut is threadedly connected to the outer side of one end of the screw rod, and one side of the nut is in conflict with one side of the bearing.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] By setting the bearings, the ink fountain wheel can be installed on the outside of the two bearings to increase its maximum speed during use, thereby improving the use experience;

[0015] By providing the bearing spacer, the problem that the bearing is difficult to rotate when the nut is tightened on its structure can be avoided, thereby improving the working efficiency of the bearing. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings required for use in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments recorded in the present utility model. For ordinary technicians in this field, other drawings can also be obtained based on these drawings.

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model provides Figure 1-Figure 3 The hand-driven bearing ink fountain wheel shown in the figure comprises: a screw 1, one end of which is fixedly connected to a nut; bearings 2, which are slidably mounted on the left and right sides of the outer side of the screw 1; bearing spacers 3, which are slidably mounted at the middle of the outer side of the screw 1; an ink fountain wheel 4, which is rotatably mounted on the outer sides of two bearings 2, wherein the bearings 2 are used to reduce the friction when the ink fountain wheel 4 rotates to increase its maximum rotation speed, and the bearing spacers 3 are used to position the two bearings 2 and avoid the problem that the bearings 2 are difficult to rotate after the nut 5 is tightened on one side of the screw 1. During installation, the screw 1 passes through the bearing 2, the bearing spacer 3 and the bearing 2, and then is tightened with the nut 5. The ink fountain wheel 4 is manually driven to quickly reel in the ink, and is suitable for installation on various ink fountains.

[0024] Furthermore, baffles are fixedly connected to the front and rear sides of the ink fountain wheel 4, and the maximum outer diameter of the baffles is larger than the outer diameter of the middle section of the ink fountain wheel 4. The baffles can limit the rope installed on the ink fountain wheel 4 to prevent dislocation.

[0025] Furthermore, positioning grooves are provided on the front and rear sides of the ink fountain wheel 4 , and the inner diameter of the positioning groove is matched with the outer diameter of the bearing 2 . The positioning groove is used to accommodate and position the bearing 2 for easy installation.

[0026] Furthermore, a through groove is provided between adjacent surfaces of the positioning groove, and the bearing spacer sleeve 3 is located on the inner side of the through groove. The through groove is used to allow the bearing spacer sleeve 3 to pass through to avoid interference.

[0027] Furthermore, a nut 5 is threadedly connected to the outer side of one end of the screw rod 1, and one side of the nut 5 is in conflict with one side of the bearing 2. The nut 5 is used to fasten this part of the structure to ensure the structural stability after installation.

[0028] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
