[0002] Because the plaster corners are most vulnerable to damage during construction and after use, the use of corner guards strengthens the wall surface and saves a lot of time due to its easy construction. Corner guards are quick to operate and easy to construct, strengthen the corner strength, and have a wide range of practical applications.

[0003] In the prior art, corner guards are divided into: external corner guards (external corners are installed at protruding corners, and most of them are large-hole profiles with a cross-sectional angle greater than 90 degrees) and internal corner guards (internal corners are installed at recessed corners, and most of them are small round holes, and the cross-sectional angle of the profile is mostly less than 90 degrees). Among them, external corner guards have a wide range of uses, so it is necessary to customize corner guards with different angles according to the usage scenarios, which will result in the need to specially configure a variety of molds during the production of corner guards, which will increase the production cost of corner guards. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a bendable and adjustable external corner protection strip so as to solve the technical problems mentioned in the above background technology.

[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0026] Example:

[0027] Reference Figure 1-Figure 4 The utility model discloses a bending adjustable external corner bead, comprising a rotating shaft 1, the outer side walls of both ends of which are convex to form a limiting member 4;

[0028] Two wing plates 2 are provided and are respectively connected to both sides of the rotating shaft 1;

[0029] The protective pad 3 has adhesive layers 5 on both sides of its inner wall and is connected to the two wing plates 2 respectively;

[0030] The top of one of the wing plates 2 contacts the stopper 4 at the top of the rotating shaft 1 , and the bottom contacts the other wing plate 2 , while the bottom of the other wing plate 2 contacts the stopper 4 at the bottom of the rotating shaft 1 .

[0031] In this embodiment, the hook member 22 of the wing plate 2 is hooked on the top of the shaft 1, and then the hook member 22 of the other wing plate 2 is hooked on the bottom of the shaft 1, so that the installation of the corner guard strip can be completed, and then the corner guard strip can be fixed at the corresponding positive corner.

[0032] When the external corner where the corner guard is installed changes, the angle of the corner guard can be adjusted by pushing one of the wing plates 2 to rotate it around the axis of the rotating shaft 1, so that the corner guard can fit perfectly at the external corner, thereby expanding the application scenarios of the corner guard.

[0033] The wing plate 2 and the rotating shaft 1 can move, so a gap for movement must be set between the wing plate 2 and the rotating shaft 1. Therefore, in order to prevent the wing plate 2 from falling off the rotating shaft 1, limiting parts 4 are set at both ends of the rotating shaft 1, and the top of one of the wing plates 2 contacts the limiting part 4 at the top of the rotating shaft 1, and the bottom contacts the other wing plate 2, while the bottom of the other wing plate 2 contacts the limiting part 4 at the bottom of the rotating shaft 1. By limiting each other, the wing plate 2 is prevented from falling off the rotating shaft 1, and the stability of the corner guard after the angle is adjusted is improved.

[0034] Although the stability of the corner guard can be improved by the limit between the wing plate 2 and the limiter 4, the gap that can be used for movement will not disappear, which will cause dust to enter the gap and affect the rotation of the wing plate 2. Therefore, a protective pad 3 is connected to the outer wall of the wing plate 2. The protective pad 3 can block the gap to reduce the entry of dust and the like, thereby increasing the service life of the corner guard. At the same time, the provision of the protective pad 3 can also reduce the impact caused by the collision of the corner guard, improve the safety of the corner guard, and reduce the damage caused by the collision of personnel.

[0035] In a further preferred embodiment of the present invention, Figure 3 As shown, the two adhesive layers 5 are symmetrically arranged on both sides of the protective pad 3 with the rotating shaft 1 as a reference, and a gap is left between the two adhesive layers 5 .

[0036] In this embodiment, because the protective pad 3 needs to protect the connection gap between the two wing plates 2 and the rotating shaft 1, the protective pad 3 needs to be covered on the outer side wall of the corner bead. Since the protective pad 3 and the wing plates 2 are connected through the adhesive layer 5, the adhesive layer 5 will interfere with the rotation of the wing plates 2 when it is attached to the rotating shaft 1, affecting the angle adjustment of the corner bead. Therefore, the adhesive layer 5 of the protective pad 3 is symmetrically arranged on both sides with the rotating shaft 1 as the reference, and a gap is left between the two adhesive layers 5 to avoid the rotating shaft 1.

[0037] When the inclination angle of the corner guard is adjusted, the distance between the two wing plates 2 will increase or decrease, which will stretch or compress the protective pad 3. Therefore, the protective pad 3 is made of high-toughness rubber, silicone and other materials, which can improve the service life of the protective pad 3 while ensuring its protective performance.

[0038] In a further preferred embodiment of the present invention, Figure 2 As shown, the wing plate 2 is composed of a guard plate 21 and a hook member 22, and the side wall of the guard plate 21 extends in a curvature to form the hook member 22 for hooking the rotating shaft 1, wherein the hook member 22 of one guard plate 21 is arranged at the top of the side wall, and the hook member 22 of the other guard plate 21 is arranged at the bottom of the side wall.

[0039] In this embodiment, because the two wing plates 2 are connected to the rotating shaft 1, and the two wing plates 2 need to be able to rotate to adjust the angle of the corner guard strip, a hook member 22 that can hook the rotating shaft 1 is set on the side wall of the guard plate 21, and the two wing plates 2 are symmetrically arranged on both sides of the rotating shaft 1. Therefore, the hook members 22 of the two guard plates 21 need to be staggered, so the hook member 22 of one of the guard plates 21 is located at the top of the side wall, and the hook member 22 of the other guard plate 21 is located at the bottom of the side wall.

[0040] In a further preferred embodiment of the present invention, Figure 2 As shown, the hook member 22 is three-fifths circular.

[0041] In this embodiment, because the angle of the external corner is sharp, a corner guard strip needs to be installed for protection. The wing plate 2 rotates with the shaft 1 through the hook member 22, and the hook member 22 is arranged on the outer wall of the shaft 1, so that the angle between the two wing plates 2 cannot accommodate the sharp end of the external corner due to the arrangement of the hook member 22, so the hook member 22 is an incomplete circle, so that the opening of the hook member 22 can avoid the sharp part of the external corner, so that the corner guard strip has the function of adjusting the angle and will not conflict with the sharp part of the external corner, making the corner guard strip more practical.

[0042] Since the hook member 22 is provided with an opening, the hook member 22 cannot be completely sleeved on the outer wall of the shaft 1. Therefore, in order to allow the hook member 22 to be stably sleeved on the outer wall of the shaft 1, the size of the opening needs to be smaller than half a circle. Therefore, under the condition of ensuring the connection stability between the hook member 22 and the shaft 1, the hook member 22 is set to be three-fifths of a circle and the size of the opening is two-fifths of a circle, so that the hook member 22 can maintain a stable connection while maximizing the usable range of the corner guard.

[0043] In a further preferred embodiment of the present invention, Figure 2 As shown, the outer diameter of the hook member 22 is the same as the outer diameter of the limiting member 4 , and a side of the hook member 22 close to the limiting member 4 is provided with an avoidance groove 6 for avoiding the limiting member 4 .

[0044] In this embodiment, by making the outer diameter of the hook member 22 the same as the outer diameter of the limiting member 4, the protective pad 3 can be more flat when it is attached to the outside of the corner guard, so that the protective pad 3 is more evenly stressed when being pulled, thereby improving the service life of the protective pad.

[0045] By providing the avoidance groove 6 for avoiding the limiting member 4 on the hook member 22, the hook member 22 can be more stably connected to the rotating shaft 1.

[0046] In a further preferred embodiment of the present invention, Figure 4 As shown, a through groove is opened downward on one side of the top of the rotating shaft 1 to form a notch 7 , and the notch 7 is arranged on a side of the rotating shaft 1 away from the protective pad 3 .

[0047] In this embodiment, by providing a notch on the side wall of the rotating shaft 1, the ability of the corner guard strip to accommodate the sharp corner can be further improved, thereby increasing the practicality of the corner guard strip.

[0048] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
