[0031] See also Figure 1-Figure 3 In the embodiment of the present application, the support 100 for supporting the steel mesh includes an angle connector 20 and a frame 10 for supporting the steel mesh in the embodiment of the present application. The frame 10 and the angle connector 20 are alternately connected to form a rectangular support 100. The steel mesh can be tightened and fixed on the support 100 through the frame 10 around the periphery to form a movable steel mesh that can be freely replaced, thereby facilitating the replacement of the steel mesh during the steel mesh printing process, saving printing costs, and improving printing efficiency.
[0032] Specifically, the corner connector 20 may be in a right-angle shape, and the two ends thereof may be respectively formed with a plug-in portion 21, which can be plugged and matched with the frame 10. Furthermore, after the four corner connectors 20 and the four frames 10 are alternately connected and assembled, a rectangular bracket 100 for tensioning and fixing the steel mesh can be formed, and the steel mesh is pressed on the bracket 100 through the surrounding frames 10 to form a movable steel mesh.
[0033] See also Figure 1-Figure 5In the embodiment of the present application, the frame 10 for supporting the steel mesh includes a main body 11 and a pressure plate 12. The main body 11 is provided with a pressure groove 111 and an installation groove 112. The installation groove 112 is used to cooperate with the connection of the corner connector 20 and the fixation of the tensioning structure; the pressure plate 12 is connected to the main body 11 along the length direction of the main body 11, and the pressure plate 12 can be opened and closed relative to the main body 11. The side of the pressure plate 12 facing the main body 11 is provided with a pressing protrusion 13, and the pressing protrusion 13 can extend into the pressing groove 111 to press the steel mesh. The side of the pressure plate 12 opposite to the main body 11 is provided with a convex rib 14.
[0034] In the frame 10 for supporting the steel mesh in the embodiment of the present application, by providing convex ridges 14 on the pressing surface 122 of the pressing plate 12, it is easier to press the pressing plate 12, so that the steel mesh can be better pressed on the frame 10, thereby avoiding affecting the tension of the steel mesh during assembly and improving the printing effect of the steel mesh.
[0035] Specifically, Figure 2 and Figure 4 As shown, the main body 11 may be a strip-shaped structure, and the pressing groove 111 and the mounting groove 112 are formed opposite to each other above and below the main body 11. Along the length direction of the main body 11, the pressing plate 12 may be connected to the edge of the pressing groove 111, and the pressing plate 12 may be opened or closed relative to the main body 11. The pressing plate 12 has a pressing surface 121 and a pressing surface 122 opposite to each other, and the pressing surface 121 faces the direction of the pressing groove 111.
[0036] Furthermore, a pressing protrusion 13 protruding toward the pressing groove 111 is formed on the pressing surface 121, and the shape of the pressing protrusion 13 can be adapted to the shape of the pressing groove 111. When the edge of the steel mesh extends above the pressing groove 111, the steel mesh can be squeezed between the pressing protrusion 13 and the inner wall of the pressing groove 111 by pressing the pressing plate 12, so that the steel mesh can be firmly assembled on the bracket 100.
[0037] The pressing surface 122 is formed with convex ribs 14 protruding in the direction opposite to the pressing groove 111, and the convex ribs 14 can be extended along the length direction of the pressing plate 12. In some embodiments, the convex ribs 14 can be set as a continuous strip structure or a spaced strip structure, and the present application does not impose any specific restrictions on this. Furthermore, the convex ribs 14 can be set at the relative position of the gap when the pressing protrusion 13 abuts against the pressing groove 111, so that the pressing position of the pressing protrusion 13 against the steel mesh is better during pressing, the pressing effect on the steel mesh is better, and the tension of the steel mesh on the bracket 100 is more moderate.
[0038] The mounting groove 112 may include a hook groove 1121 and a connection groove 1122. The shape of the hook groove 1121 may be adapted to the hook portion of the tensioning structure. The hook groove 1121 is mainly used to cooperate with the tensioning of the hook portion of the tensioning structure to limit the installation position of the movable steel mesh. The connection groove 1122 may be connected to the hook groove 1121 and extend to a side opposite to the hook groove 1121. The connection groove 1122 is mainly used to be plugged with the plug-in portion 21 of the corner connector 20 to make the connection between the corner connector 20 and the frame 10 more stable. The plug-in portion 21 of the corner connector 20 is adapted to the shape of the mounting groove 112, thereby making the connection between the corner connector 20 and the frame 10 more secure.
[0039] See also Figure 4 and Figure 5 In some embodiments, the pressing groove 111 includes a first abutting wall 1111 that is opposite to the pressing protrusion 13, and also includes a second abutting wall 1112 that is opposite to the pressing plate 12. The pressing protrusion 13 includes a third abutting wall 131 facing the first abutting wall 1111, and the pressing plate 12 includes a fourth abutting wall 123 facing the second abutting wall 1112.
[0040] Among them, the first abutment wall 1111 is used to cooperate with the third abutment wall 131 to press the steel mesh to prevent the steel mesh from loosening. The second abutment wall 1112 and the fourth abutment wall 123 are mainly used to limit the extended position of the steel mesh relative to the main body 11 when pressing, and can also improve the firmness of the steel mesh compression.
[0041] See also Figure 4 and Figure 5 In some embodiments, the angle between the first abutting wall 1111 and the second abutting wall 1112 is not greater than 90°. For example, the angle between the first abutting wall 1111 and the second abutting wall 1112 can be 90°, 85°, 80° or 70°, so that the steel mesh can be more firmly and stably pressed by the first abutting wall 1111 and the second abutting wall 1112, thereby preventing the steel mesh from loosening from the frame 10.
[0042] The first abutting wall 1111 and the second abutting wall 1112 are smoothly transitioned to avoid damaging the steel mesh when the pressing protrusion 13 presses the steel mesh downward.
[0043] In some embodiments, when the pressure plate 12 is buckled, the distance between the third abutting wall 131 and the first abutting wall 1111 is not less than the thickness of the steel mesh. In this way, the steel mesh can be better squeezed between the first abutting wall 1111 and the third abutting wall 131, avoiding the situation where the steel mesh cannot be pressed between the two. Of course, the distance between the third abutting wall 131 and the first abutting wall 1111 is approximately close to the thickness of the steel mesh, and the connection effect between the steel mesh and the frame 10 is better, and the connection is more firm and stable.
[0044] In some embodiments, the first abutting wall 1111 and the third abutting wall 131 are respectively provided with convex strips (not shown in the figure), and the convex strips on the first abutting wall 1111 and the convex strips on the third abutting wall 131 are staggered.
[0045] In this way, the convex strips can increase the friction between the steel mesh and the first abutting wall 1111 and the third abutting wall 131, so that the handheld game console effect of the steel mesh is better and the loosening of the steel mesh is avoided.
[0046] Specifically, the convex strips can be extended along the length direction of the main body 11, the convex strips on the first abutting wall 1111 protrude toward the third abutting wall 131, and the convex strips on the third abutting wall 131 protrude toward the first abutting wall 1111. The convex strips on the first abutting wall 1111 and the convex strips on the third abutting wall 131 are staggered to avoid the relative convex strips from squeezing and reducing the contact area between the steel mesh and the two abutting walls, thereby affecting the tensioning effect. It should be noted that the surface of the convex strips can be smooth to avoid damaging the steel mesh during clamping.
[0047] See also Figure 4 and Figure 5 In some embodiments, a connecting strip 15 is provided at the connection between the pressing plate 12 and the main body 11 . When the pressing plate 12 is buckled, the connecting strip 15 exerts an elastic force on the pressing plate 12 in a direction opposite to the connecting strip 15 .
[0048] Thus, when the pressing plate 12 is buckled, the third abutting wall 131 of the pressing protrusion 13 exerts a greater pressure toward the first abutting wall 1111 of the pressing groove 111 under the elastic force of the connecting strip 15, thereby effectively increasing the pressing force on the steel mesh and preventing the steel mesh from loosening.
[0049] Specifically, the connecting strip 15 can be in a semicircular structure to avoid affecting the opening and closing of the pressing plate 12 relative to the main body 11, and can also effectively provide a certain elastic force to the pressing plate 12, so that the squeezing effect on the steel mesh is better. Of course, the connecting strip 15 can also be in an angular or bent structure, as long as it can provide a certain elastic force to the pressing plate 12. The present application does not limit the specific shape of the connecting strip 15.
[0050] In some embodiments, the main body 11 is provided with a convex edge 16, and the convex edge 16 extends in a direction opposite to the opening of the pressure plate 12. The convex edge 16 can be specifically extended from the main body 11 in a direction opposite to the center of the bracket 100, so that the bracket 100 can be better assembled under the action of the convex edge 16, and the assembly will be more stable, so that the bracket 100 can be more accurately matched and fixed with the tensioning structure.
