DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Reference Figure 1 、 Figure 2 and Figure 3, the utility model provides an embodiment: a building corner guard comprises a first hard protective plate 1 and a connecting rod 14, a second hard protective plate 3 is provided on the rear side of the first hard protective plate 1, an elastic protective plate 4 is provided inside the first hard protective plate 1, a plurality of grooves 5 are opened on one side of the elastic protective plate 4, a fixing rod 6 is fixedly connected to the inside of the groove 5, a first spring 7 is provided on the outside of the fixing rod 6, both ends of the two first springs 7 are fixedly connected to a U-shaped block 8, a plurality of U-shaped blocks 8 are respectively slidably connected to the outside of the corresponding fixing rod 6, a first rotating shaft 9 is rotatably connected to the inside of the U-shaped block 8, a support plate 10 is provided on one side of the first hard protective plate 1 and the second hard protective plate 3, and the upper and lower inner portions of the two support plates 10 are fixedly connected to the fixing rod 6. A cavity 11 is opened on each side, and a plurality of limit plates 12 are inserted into the interior of the plurality of cavities 11. The interior of each two limit plates 12 is rotatably connected to a second rotating shaft 13, and the plurality of second rotating shafts 13 are respectively connected to the corresponding first rotating shaft 9 through a connecting rod 14. A T-shaped rod 16 is fixedly connected to the middle and upper part of one side of the support plate 10, and a second spring 15 is provided on the outer side of the T-shaped rod 16. One end of the second spring 15 is respectively fixedly connected to one side of the elastic protective plate 4. A disassembly mechanism 2 is provided inside the support plate 10. The sizes of the plurality of U-shaped blocks 8 match the internal sizes of the corresponding grooves 5, and the height of the first hard protective plate 1 and the second hard protective plate 3 is consistent with the overall height of the elastic protective plate 4;

[0041] Specifically, when the corner is hit by an external impact, the first hard protective plate 1 and the second hard protective plate 3 will first contact and absorb part of the impact force. In this process, they will squeeze the second spring 15 located between them, causing the second spring 15 to deform, thereby converting the impact force into the elastic potential energy of the second spring 15, achieving a preliminary buffering effect. As the impact force continues to act, the first hard protective plate 1 and the second hard protective plate 3 will further move toward the elastic protective plate 4. In this process, the second rotating shaft 13 will rotate along with the movement of the support plate 10, and the first rotating shaft 9 connected thereto will also rotate, and the connecting rod 14 will move accordingly, thereby driving the U-shaped block 8 to move from the outside of the fixed rod 6 to the middle. In this process, the U-shaped block 8 will squeeze the first spring 7, causing the first spring 7 to further deform, thereby absorbing more impact force. This multi-level buffering mechanism enables the corner protection structure to more effectively cope with impact forces of various intensities.

[0042] Reference Figure 4 、 Figure 5 and Figure 6The disassembly mechanism 2 includes an open slot 201 and a transmission belt 205. The open slot 201 is opened on one side of the support plate 10. The upper and lower sides of the two open slots 201 are rotatably connected to the screw rods 202. One end of the multiple screw rods 202 respectively penetrates the corresponding cavities 11 and is threadedly connected to the movable rod 203. One end of the multiple movable rods 203 sequentially penetrates the corresponding limit plates 12. The outer side of the screw rods 202 is fixedly connected to the pulleys 204. The multiple pulleys 204 are respectively connected through the transmission belt 205.

[0043] Specifically, when the first hard protective plate 1 and the second hard protective plate 3 need to be replaced, the limit rod 209 is first turned out from the hole 208 to release the limit fixation of the second hard protective plate 3, and then one of the screw rods 202 is rotated. As the screw rod 202 rotates, the pulley 204 on its outer side will also rotate. At the same time, the pulley 204 on the other screw rod 202 will also rotate through the transmission belt 205. At this time, the movable rod 203 on the screw rod 202 will move to one side inside the slide groove 207 to release the limit fixation of the limit plate 12, so that the first hard protective plate 1 or the second hard protective plate 3 can be removed smoothly, and it is relatively simple to disassemble and replace the first hard protective plate 1 and the second hard protective plate 3.

[0044] Reference Figure 2 , a plurality of support rods 17 are fixedly connected to one side of the first hard protective plate 1 and the second hard protective plate 3 at equal distances, and one end of the plurality of support rods 17 is fixedly connected to one side of the corresponding support plate 10;

[0045] Specifically, the support rod 17 can evenly distribute the impact force exerted on the first hard protective plate 1 and the second hard protective plate 3 on the support plate 10 , thereby making the subsequent buffer structure work more stably.

[0046] Reference Figure 1 and Figure 2 , a plurality of rubber strips 18 are fixedly connected to the outside of the first hard protective plate 1 and the second hard protective plate 3 at equal distances, and a rubber pad 19 is fixedly connected to the outside of the bending part of the first hard protective plate 1;

[0047] Specifically, the first hard protective plate 1 and the second hard protective plate 3 can be further protected by the cooperation between the rubber strip 18 and the rubber pad 19 .

[0048] Reference Figure 3 , a plurality of mounting holes 20 are evenly spaced on the outer side of the elastic protection plate 4, and the positions of the mounting holes 20 on both sides are symmetrical;

[0049] Specifically, the installation hole 20 can facilitate the disassembly and installation of the elastic protection plate 4 .

[0050] Working principle: When using the structure, first carry it to the corner of the wall to be protected, and then fix the elastic protective plate 4 at the corner of the wall through the cooperation between the mounting hole 20 and the external bolt, and then the first hard protective plate 1 and the second hard protective plate 3 can be installed on the outside of the elastic protective plate 4 through the disassembly mechanism 2. This method can not only effectively absorb impact force, but also enhance the rigidity and wear resistance of the structure. When subjected to external impact, the first hard protective plate 1 and the second hard protective plate 3 will first squeeze the second spring 15 to buffer part of the impact force. When the first hard protective plate 1 and the second hard protective plate 3 move toward the elastic protective plate 4, the second rotating shaft 13 will rotate accordingly, and the first rotating shaft 9 will also rotate accordingly through the connecting rod 14, thereby driving the U-shaped block 8 to move toward the middle outside the fixing rod 6 to squeeze the first spring 7, which can further buffer the impact force. When the first and second hard protective plates 1 and 3 are damaged, the limiting rod 209 can be turned out of the hole 208 to release the limiting fixation of the second hard protective plate 3, and then the corresponding one of the screw rods 202 is rotated, and the pulley 204 on the outside of the screw rod 202 will rotate accordingly, and the pulley 204 on the other screw rod 202 will also rotate accordingly through the transmission belt 205. At this time, the movable rod 203 on the screw rod 202 will move to one side inside the slide groove 207, and the limiting fixation of the limiting plate 12 can be released. At this time, the damaged first hard protective plate 1 or the second hard protective plate 3 can be disassembled and replaced. It is relatively simple to disassemble and replace the first and second hard protective plates 1 and 3, thereby reducing the replacement and maintenance costs.

[0051] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
