Description

Technical Field

[0001] The utility model relates to the technical field of corner protection strips, in particular to an impact-resistant and fall-proof corner protection strip. Background Art

[0002] In the process of building manufacturing in my country, the traditional way of building corners is to use manual or simple tools to trim the corners to make the wall beautiful. In addition, during the construction process, construction workers may bump into the corners, causing damage to the corners and repairing them again, so the use of corner guards is very necessary.

[0003] Chinese patent publication number CN209874382U discloses an impact-resistant and anti-falling corner guard strip, comprising a first guard strip and a second guard strip, wherein one end of the first guard strip is connected to the second guard strip to form a corner connection portion, the other ends of the first guard strip and the second guard strip are open ends, the main body thickness of the corner connection portion is greater than the thickness of the first guard strip and the second guard strip, and the first guard strip and the second guard strip are both provided with a plurality of fixing holes.

[0004] The above patent uses fixing holes to install corner guards. Since the corner guards are in direct contact with the wall, they will be deformed when hit. After the corner guards are deformed, the size of the fixing holes will easily expand, and the rivet heads will not be able to contact the aperture of the fixing holes. The rivets may even be directly ejected due to the elastic force of the corner guards themselves. At this time, it is difficult for the rivets to effectively fix the corner guards, and when the corner guards are hit again, they are prone to fall off. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an impact-resistant and anti-falling corner guard strip so as to solve the technical problems mentioned in the above background technology.

[0008] Furthermore, the corner fitting belt is arranged in an arc shape, and a triangular groove is provided in the middle of the inner arc surface of the corner fitting belt.

[0009] Furthermore, the anti-collision plate includes two metal straight plates and an arc-shaped metal plate, the two metal straight plates are fixedly connected to one end of the two arc-shaped elastic members respectively, and the adjacent ends of the two metal straight plates are commonly connected to the arc-shaped metal plate.

DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Example:

[0024] Reference Figure 1-Figure 4 The utility model discloses an impact-resistant and anti-falling corner guard strip, comprising a corner fitting strip 1, two ends of the corner fitting strip 1 are fixedly connected with positioning plates 2, an end of the positioning plate 2 away from the corner fitting strip 1 is provided with an arc-shaped elastic member 3, the ends of the two arc-shaped elastic members 3 away from the positioning plate 2 are commonly connected with an anti-collision plate 4, and the inner side of the anti-collision plate 4 is provided with a guide mechanism 5 connected with the positioning plate 2.

[0025] In this embodiment, when installing the corner guard strip, the inner middle part of the corner fitting strip 1 is aligned with the top edge of the corner, and the two positioning plates 2 are respectively pressed against the wall surfaces on both sides of the corner, and the positioning plates 2 are fixed to the wall surfaces by rivets, and the anti-collision plate 4 is connected to the positioning plate 2 by two arc-shaped elastic members 3, and the arc-shaped elastic members 3 are made of elastic rubber and have a U-shaped cross-section. The two sides of the anti-collision plate 4 are slidably connected to the positioning plate 2 by the setting of the guide mechanism 5 to avoid the problem of the anti-collision plate 4 sinking due to gravity.

[0026] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the corner fitting belt 1 is arranged in an arc shape, and a triangular groove 11 is provided in the middle of the inner arc surface of the corner fitting belt 1 .

[0027] In this embodiment, when the corner fitting tape 1 is installed at the corner, the top edge of the corner is embedded into the inside of the triangular groove 11, so as to achieve the effect of quickly positioning the position of the corner fitting tape 1.

[0028] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the anti-collision plate 4 includes two metal straight plates 41 and an arc-shaped metal plate 42. The two metal straight plates 41 are fixedly connected to one end of the two arc-shaped elastic members 3 respectively, and the adjacent ends of the two metal straight plates 41 are commonly connected to the arc-shaped metal plate 42.

[0029] In this embodiment, the metal straight plate 41 is used to install the arc-shaped metal plate 42, so that the arc-shaped metal plate 42 is installed at the vertex position of the corner of the wall. When hit, the impact force generated by the impact is relieved through the deformation of the arc-shaped metal plate 42, thereby achieving the effect of protecting the corner of the wall. After the arc-shaped metal plate 42 is deformed, the energy generated extends to the inside of the arc-shaped elastic member 3. Since the arc-shaped elastic member 3 is made of elastic rubber, it will absorb a large amount of energy, avoiding the impact force from being transmitted to the positioning plate 2, thereby preventing the positioning plate 2 from deforming and causing the rivet to pop out.

[0030] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the guide mechanism 5 includes a fixed slide plate 51, and the fixed slide plate 51 is fixedly connected to the side of the metal straight plate 41 close to the positioning plate 2. A guide rail 52 fixedly connected to the positioning plate 2 is installed on one side of the fixed slide plate 51, and an end of the fixed slide plate 51 inserted into the guide rail 52 is fixedly connected with an arc spring sheet 53.

[0031] In the present embodiment, the cross-section of the fixed slide plate 51 is in the shape of an "I", and the track groove of the guide rail 52 is in the shape of a "convex" character. Both side edges of the fixed slide plate 51 are in contact with the two inner side surfaces of the guide rail 52, thereby achieving the purpose of fixing the anti-collision plate 4. The arc-shaped spring sheet 53 is arranged so that a gap is provided between the end surface of the fixed slide plate 51 and the inner groove surface of the guide rail 52. When the anti-collision plate 4 is hit, the arc-shaped spring sheet is arranged to prevent the impact force generated by the impact from being transmitted to the positioning plate 2, thereby further protecting the positioning plate 2.

[0032] In a further preferred embodiment of the present invention, Figure 1-4 As shown, two positioning slots 43 are formed inside the metal straight plate 41 , and rivet holes 44 are formed at positions of the positioning plate 2 corresponding to the two ends of the positioning slots 43 .

[0033] In this embodiment, the positioning groove 43 is provided to facilitate the insertion of the rivet, and the rivet is inserted into the rivet hole 44, and the rivet head contacts the positioning plate 2, so as to achieve the purpose of fixing the positioning plate 2 on the wall surface.

[0034] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the inner arc surface of the arc-shaped metal plate 42 is fixedly connected with a metal elastic plate 45, the middle part of the metal elastic plate 45 has an arc-shaped bending part 46, and the outer arc surface of the arc-shaped bending part 46 is fixedly connected with the middle part of the inner arc surface of the arc-shaped metal plate 42, and the two ends of the metal elastic plate 45 are respectively in contact with the two positioning plates 2.

[0035] In this embodiment, by providing the metal elastic plate 45 and supporting the arc-shaped metal plate 42 through two positioning plates 2, the upper limit of the impact absorption of the arc-shaped metal plate 42 is increased, thereby achieving the effect of improving the strength of the corner guard strip.

[0036] 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.
