Technical Field

[0001] This utility model relates to the field of wallpaper seam treatment technology, specifically a wallpaper seam treatment device for coating with waterproof adhesive. Background Technology

[0002] Wallpaper installation is a common wall decoration method in interior design. To ensure the aesthetics and durability of the wallpaper, the treatment of the seams is particularly important.

[0003] In the prior art, a wallpaper application auxiliary device with authorization announcement number CN218367218U includes a connecting rod, a telescopic rod rotatably connected to the top of the connecting rod, and an adjustment knob provided at the bottom of the connecting rod and the telescopic rod. A connecting block is fixedly connected to the top of the telescopic rod, and three through holes are opened on the top surface of the connecting block. A first branch and two second branches are movably connected in the through holes. An installation frame is fixedly connected between the two second branches. The top of the installation frame is hollow and rotatably connected to a roller. Two sets of rollers are provided.

[0004] In the above scheme, the roller on the second branch and the applicator on the first branch can treat the wallpaper seams coated with waterproof adhesive on the wall surface and at high corners. However, the device has some shortcomings in actual use: when installing the second and first branches, bolts are used to connect them to the connecting block. This installation method is cumbersome, requires tools for disassembly and installation, is inconvenient to operate, and the bolts are prone to loosening during frequent use, affecting the stability of the device.
