[0046] In addition, the shapes of the first connecting socket 34 and the second connecting socket 35 are not limited to the flat shape, and can also be other shapes, such as serrated, wavy, etc. The shapes of the first limiting concave surface 342 and the second limiting concave surface 352 are not limited to the smooth arc shape, and can also be other shapes, such as serrated, wavy, etc.
[0047] The assembly method of the connecting part 1 will be described below.
[0048] As Figure 4 shown, first, the adjusting head 6 is inserted into the rotating cavity 32 of the corner connector 3. Then, the first plug connector 4 is docked with the corner connector 3, so that the first plugging convex block 412 of the first plug connector 4 abuts against the adjusting head 6. According to the same scheme, the second plug connector 5 is installed. Finally, the main cross bar 2 is plugged on the first plug connector 4.
[0049] The frameless painting assembly with the tension adjusting structure can be used to construct a frameless painting combination system, which also includes several elastic clamping strips 7, and the clamping strips 7 cooperate with the cross bar groove 22, the corner groove 33, the first groove 421 and the second groove 521.
[0050] It should be noted that the clamping strip 7 has a certain elasticity and is made of plastic or nylon or resin.
[0051] The usage method of the frameless painting combination system will be described below.
[0052] As Figure 14 shown, the four connecting parts 1 are plugged and combined in a head-to-tail connection manner, and the canvas 8 is placed above the frameless painting combination system.
[0053] Then, the four side edges of the canvas 8 are turned over and tightly wrapped around the corresponding main cross bar 2 of the connecting part 1 as much as possible, and the clamping strip 7 is snapped into the corresponding cross bar groove 22, corner groove 33, first groove 421 and second groove 521, so that the canvas 8 is preliminarily tensioned on the corresponding connecting part 1, as Figure 15 shown.
[0054] As Figure 16 and Figure 17 shown, at this time, the first positioning plane 611 of the adjusting head 6 abuts against the end face of the first plugging convex block 412, and the second positioning plane 612 abuts against the end face of the second plugging convex block 512.
[0055] As Figure 18 and Figure 19As shown, the user inserts a screwdriver or other suitable tool into the adjustment socket 621 and rotates the adjustment head 6 counterclockwise, so that the first positioning plane 611 abuts against the end surface of the second plug-in protrusion 512, and the outer circular wall of the adjustment disk 61 of the adjustment head 6 abuts against the end surface of the first plug-in protrusion 412. As a result, the distance between the main horizontal bar 2 and the corner connector 3 increases, and the canvas 8 is tightened in the X direction.
[0056] like Figure 20 and Figure 21 As shown, continue to rotate the adjusting head 6 counterclockwise, so that the outer circular wall of the adjusting disk 61 of the adjusting head 6 abuts against the end face of the second plug-in protrusion 512. At this time, the outer circular wall of the adjusting disk 61 of the adjusting head 6 still keeps abutting against the end face of the first plug-in protrusion 412, so that the canvas 8 is tightened in the Y direction.
[0057] The other three adjustment heads 6 are operated in the same manner, so that the entire canvas 8 is completely tightened in the XY plane.
[0058] The frameless painting assembly with a tension adjustment structure can be adjusted to extend as needed, has good adaptability, and is particularly suitable for the field of frameless painting DIY. At the same time, since the canvas is fixed by a card strip, no physical damage will be caused to the canvas, and the frameless painting assembly and the canvas can be used repeatedly.
[0059] Without limitation to this, any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope defined in the claims.
