Description

Technical Field

[0001] The utility model relates to the technical field of corner guards, in particular to an anti-cracking corner guard with multiple support components. Background Art

[0002] In the process of building manufacturing in our country, traditional construction of wall corners is to use manual labor or some simple tools to trim the wall corners to make the walls beautiful. Moreover, during the construction process, construction workers may touch the wall corners, causing damage to the wall corners and requiring repair work again. Therefore, the use of corner guards is very necessary.

[0003] In the prior art, corner guards are generally made by bending a whole piece of elastic material or a metal plate. When in use, the corner guards are adhered to the wall corners to achieve the effect of protecting the walls. However, in the event of an impact accident on the wall corners, there are not only cases of direct impact with the wall corners, but also cases of impact with the positions adjacent to the wall corners on the walls. In this case, the wall corners will still be damaged, and different impact angles will also cause different degrees of damage.

[0004] And these above-mentioned problems are difficult to be protected by a whole piece of corner guard, and it is also easy to cause tearing damage to the corner guard when the impact angles are different. Summary of the Utility Model

[0005] In view of the deficiencies of the prior art, the purpose of the utility model is to provide an anti-cracking corner guard with multiple support components to solve the technical problems mentioned in the above background art.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0007] An anti-cracking corner guard with multiple support components includes a corner guard net, which is jointly connected by two grid plates and a connecting rotating shaft. A number of first support components are arranged on one side of each of the two grid plates. One end of each of the two grid plates close to the connecting rotating shaft is jointly connected with a second support component. The first support component and the second support component are jointly connected to a telescopic corner guard.

[0008] Further, the first support component includes a mounting rod and a guiding column. The mounting rod is fixedly connected to the cross beam of the grid plate, and the guiding column is connected to the end of the mounting rod away from the grid plate.

[0009] Further, the second support component includes a first arc-shaped piece and a second arc-shaped piece. Two ends of the first arc-shaped piece are respectively fixedly connected to the two grid plates. Two ends of the second arc-shaped piece are fixedly connected to two ends of the first arc-shaped piece, and there is a cavity between the first arc-shaped piece and the second arc-shaped piece.

[0010] Furthermore, the telescopic corner guard strip includes two extension plates. One end of the two adjacent extension plates is connected with a telescopic joint. The extension plates are made of metal, and sliding grooves matching the guide posts are provided at positions corresponding to the first support member on the extension plates. The telescopic joint is an arc-shaped rubber plate, and a number of evenly distributed stretching grooves are provided on both side surfaces of the telescopic joint.

[0011] Furthermore, an elastic clamping post is arranged in the middle of the inner arc surface of the telescopic joint. One end of the elastic clamping post is fixedly connected with a ball head, and a closed groove is jointly opened inside the elastic clamping post and the ball head.

[0012] Furthermore, a locking groove is provided at a position corresponding to the elastic clamping post on the second arc-shaped piece, and the width of the locking groove is equal to the width of the elastic clamping post.

[0013] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0014] 1. For this anti-cracking corner guard strip with multiple support components, when the two sides of the telescopic corner guard strip are impacted in an oblique angle direction, a part of the impact force is transmitted to the inside of the grid plate through the extension plate and the guide post for dispersion, while the other part will push the extension plate to slide in the linear direction of the guide post and stretch the telescopic joint. By stretching the telescopic joint, the purpose of reducing the impact force is achieved, preventing the wall from being damaged, and thus achieving the effect of protecting the wall when the corner guard strip is impacted in an oblique direction.

[0015] 2. For this anti-cracking corner guard strip with multiple support components, through the arrangement of the stretching grooves sequentially distributed on both sides of the telescopic joint, the telescopic joint can be extended in the length direction. When the two sides of the telescopic corner guard strip are impacted in an oblique angle direction and the extension plate moves, the problem of the corner guard strip being torn can be avoided through the telescopic movement of the telescopic corner guard strip, effectively improving the service life of the corner guard strip.

[0023] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Embodiment:

[0025] Refer to Figures 1 - 5 , a crack-resistant corner guard strip with multiple support components disclosed by the present utility model includes a corner guard net 1, the corner guard net 1 is jointly connected by two mesh plates 11 and a connecting rotating shaft 12, a plurality of first support components 2 are arranged on one side of each of the two mesh plates 11, a second support component 3 is jointly connected to one end of the two mesh plates 11 close to the connecting rotating shaft 12, and a telescopic corner guard strip 4 is jointly connected by the first support component 2 and the second support component 3.

[0026] In this embodiment, when in use, the corner guard net 1 is pasted on the corner of the wall, so that the connecting rotating shaft 12 and the wall edge are in the same position, and the two mesh plates 11 are attached to the two walls. Honeycomb-shaped holes are formed inside the mesh plate 11. The first support component 2 is used to fix both sides of the telescopic corner guard strip 4 to prevent the corner guard strip from warping and falling off, and the second support component 3 fixes the middle part of the inner side of the telescopic corner guard strip 4, so as to achieve the effect of installing the corner guard strip.

[0027] In a further preferred embodiment of the present utility model, as Figures 1 - 5As shown, the first support member 2 includes a mounting rod 21 and a guide post 22. The mounting rod 21 is fixedly connected to the cross beam of the grid plate 11, and the guide post 22 is connected to one end of the mounting rod 21 away from the grid plate 11.

[0028] In this embodiment, through the arrangement of the mounting rod 21 and the guide post 22, both sides of the telescopic corner guard 4 are slidably connected to the grid plate 11. When the side of the corner guard is impacted in the bevel direction, the energy generated by the impact causes the side end of the telescopic corner guard 4 to move, achieving the purpose of consuming the energy generated by the impact, and changing the angle of the impact through side sliding, achieving the effect of protecting the wall.

[0029] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, the second support member 3 includes a first arc-shaped piece 31 and a second arc-shaped piece 32. Both ends of the first arc-shaped piece 31 are respectively fixedly connected to the two grid plates 11, both ends of the second arc-shaped piece 32 are fixedly connected to both ends of the first arc-shaped piece 31, and there is a cavity 33 between the first arc-shaped piece 31 and the second arc-shaped piece 32.

[0030] In this embodiment, the first arc-shaped piece 31 and the second arc-shaped piece 32 together form a pipe fitting with a cavity 33. When the edge of the corner is impacted, the second arc-shaped piece 32 and the first arc-shaped piece 31 are deformed by the impact, and then the energy generated by the impact is consumed through the deformation, achieving the effect of protecting the corner.

[0031] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, the telescopic corner guard 4 includes two extension plates 41. One end of the two adjacent extension plates 41 is commonly connected with a telescopic joint 42. The extension plates 41 are made of metal, and sliding grooves 43 matching the guide posts 22 are provided at positions corresponding to the first support member 2 on the extension plates 41. The telescopic joint 42 is an arc-shaped rubber plate, and a number of evenly distributed stretching grooves 44 are provided on both side surfaces of the telescopic joint 42.

[0032] In this embodiment, through the arrangement of two extension plates 41 and the expansion joint 42, and the extension plate 41 and the expansion joint 42 are fixedly connected by rivets. When the two sides of the telescopic corner guard 4 are impacted, that is, the extension plate 41 is impacted. When the impact direction is perpendicular to the extension plate 41, the generated impact force is transferred to the grid plate 11 through the extension plate 41 and the guide post 22. Through the arrangement of the internal honeycomb holes of the grid plate 11, the impact force is largely dispersed, achieving the effect of protecting the wall. When the impact direction forms an angle with the extension plate 41, a part of the impact force is transmitted to the inside of the grid plate 11 through the extension plate 41 and the guide post 22 for dispersion, while the other part will push the extension plate 41, causing it to slide in the linear direction of the guide post 22 and stretch the expansion joint 42. By stretching the expansion joint 42, the purpose of reducing the impact force is achieved. Through the arrangement of the expansion grooves 44 distributed on both sides of the expansion joint 42 in sequence, the expansion joint 42 can be extended in the length direction, thereby effectively preventing the problem that the corner guard is easily torn when subjected to an oblique impact. The sliding groove 43 is provided for connecting the extension plate 41 and the guide post 22.

[0033] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, an elastic clamping post 421 is arranged in the middle of the inner arc surface of the expansion joint 42. One end of the elastic clamping post 421 is fixedly connected with a ball head 422, and a closed groove 423 is jointly opened inside the elastic clamping post 421 and the ball head 422.

[0034] In this embodiment, the elastic clamping post 421 is arranged to fix the middle part of the expansion joint 42 on one side of the second arc-shaped piece 32. During use, through the arrangement of the closed groove 423, the shapes of the ball head 422 and the elastic clamping post 421 can be changed, so that the ball head 422 can be inserted into the locking groove 321. After the ball head 422 completely passes through the locking groove 321, the elastic clamping post 421 expands and is clamped into the locking groove 321, achieving the effect of fixing the expansion joint 42.

[0035] In a further preferred embodiment of the present utility model, as Figures 1 - 5 shown, a locking groove 321 is opened at a position corresponding to the elastic clamping post 421 on the second arc-shaped piece 32, and the width of the locking groove 321 is equal to the width of the elastic clamping post 421.

[0036] In this embodiment, the locking groove 321 is arranged to fix the elastic clamping post 421, and since the width of the locking groove 321 is equal to the width of the elastic clamping post 421, the effect of improving the stability of the elastic clamping post 421 after installation is achieved.

[0037] The embodiments of this specific implementation manner are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model shall be covered within the protection scope of the present utility model.
