[0002] During the centralized renovation of newly delivered residential areas, a large amount of decoration materials need to be delivered from the public areas of the buildings to the indoor areas. Most of the walls in the public areas of the residential buildings have been tiled according to the delivery standards. During the transportation of decoration materials, it is very easy to bump against the tiles at the corners of the walls, causing the tiles to collapse. The tiles at the corners of the walls are like saw teeth before the homeowners move in. The traditional protection of the corners of the walls is to use ordinary "L"-shaped protection strips with tape or glass glue to stick on the tiles. When the protection strips are removed, it will leave glue marks on the tile surface that are difficult to remove. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 Shown: A tile surface protection strip at the outside corner of a wall, comprising a first protection plate, a second protection plate and a pull rod 3; a first connecting tube 1 is fixed on one edge of the first protection plate; a second connecting tube 2 is fixed on one edge of the second protection plate; the first protection plate and the second protection plate are two equal-sized rectangular strips.

[0029] The pull rod 3 passes through the first connecting tube 1 and the second connecting tube 2 to connect the first protective plate and the second protective plate together in the form of a variable angle, and the first protective plate and the second protective plate can rotate relative to each other; the pull rod 3 is axially free and circumferentially fixed relative to the first connecting tube 1, and the pull rod 3 cannot rotate in the first connecting tube 1, but can slide; the pull rod 3 is axially free and circumferentially free relative to the second connecting tube 2, and the pull rod 3 can both rotate and slide in the second connecting tube 2.

[0030] The boss 4 at the first end of the pull rod 3 stops at the outer pipe opening of the first connecting pipe 1, and the boss 4 limits the axial movement of the pull rod 3. The second end of the pull rod 3 extends from the outer pipe opening of the second connecting pipe 2. The extended part is engraved with threads and connected to the nut 5. The nut 5 stops at the outer pipe opening of the second connecting pipe 2; the nut 5 is a butterfly nut.

[0031] The inner tube mouth of the first connecting tube 1 is in sliding contact with the second connecting tube 2, and the end face of the inner tube mouth of the first connecting tube 1 is a spiral inclined surface along the axial direction; a support plate 6 extends axially from the upper edge of the inner tube mouth of the second connecting tube 2, and the thickness of the support plate 6 is equal to the wall thickness of the second connecting tube 2. The end face of the support plate 6 is in sliding contact with the inner tube mouth of the second connecting tube 2, and the end face of the support plate 6 is an inclined surface matching the spiral inclined surface; when the nut 5 is tightened, it cooperates with the boss 4 to clamp the first connecting tube 1 and the second connecting tube 2. After the first connecting tube 1 and the second connecting tube 2 are compressed, the support plate 6 slides down along the spiral inclined surface. While sliding down, the second connecting tube 2 rotates, forcing the support plate 6 to slide along the spiral inclined surface of the second connecting tube 2, and the angle between the first protective plate and the second protective plate decreases while moving toward each other.

[0032] Since the first protection plate and the second protection plate are attached to the wall, the tie rod 3 is axially free and circumferentially fixed relative to the first connecting pipe 1 . Therefore, when the nut 5 is rotated, the tie rod 3 is fixed and the nut 5 moves on the tie rod 3 .

[0033] A suction cup 7 is arranged on the inner side surface of the angle between the first protective plate and the second protective plate. When the angle between the first protective plate and the second protective plate is reduced, the suction cup 7 is pressed tightly so that the suction cup 7 is more firmly adsorbed on the tile.

[0034] like Figure 6 , Figure 7 As shown: the first protection plate includes a first frame 8 and a first soft plate 9, the first connecting pipe 1 is fixedly connected to the first frame 8, and the first soft plate 9 is covered on the outside of the angle of the first frame 8.

[0035] The second protection plate includes a second frame 10 and a second soft plate 11 . The second connecting pipe 2 is fixedly connected to the second frame 10 . The second soft plate 11 is wrapped around the outside of the angle of the second frame 10 . The suction cup 7 is installed on the first frame 8 and the second frame 10 .

[0036] The first frame 8 and the second frame 10 constitute the supporting structure of the protection strip, and the first soft board 9 and the second soft board 11 serve as a soft anti-collision structure.

[0037] Arc-shaped protection plates 12 are distributed on the adjacent edges of the first soft plate 9 and the second soft plate 11. The arc-shaped protection plates on the first soft plate and the second soft plate are cross-distributed and close to each other. The curvature of the arc-shaped protection plates on the first soft plate and the second soft plate is less than 90° and greater than 45°. The arc-shaped protection plates 12 on the first soft plate 9 and the second soft plate 11 are staggered with each other, forming protection on the outside of the first connecting tube 1 and the second connecting tube 2 without affecting the angle change of the first protection plate and the second protection plate.

[0038] The suction cup 7 is installed in the long hole on the first frame 8 and the second frame 10. The long hole is parallel to the pull rod 3. The suction cup 7 can move in the long hole. The angle change of the first protective plate and the second protective plate is accompanied by the translation of the first protective plate and the second protective plate. The long hole eliminates the rubbing of the suction cup 7 when the first protective plate and the second protective plate translate.

[0039] The pull rod 3 includes a polygonal column section 3.1 and a cylindrical section 3.2. The inner hole of the first connecting tube 1 is a polygonal hole that matches the polygonal column section 3.1. The inner hole of the second connecting tube 2 is a circular hole that matches the cylindrical section 3.2. The part of the cylindrical section 3.2 that extends from the outer pipe opening of the second connecting tube 2 is engraved with threads.

[0040] The first frame 8 and the second frame 10 are made of hard plastic, the first soft board 9 and the second soft board 11 are made of rubber soft boards, and the outer edges of the first soft board 9 and the second soft board 11 parallel to the pull rod 3 are rounded.

[0041] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
