[0037] See also Figure 1-5A double-layer structure buffer corner protector comprises a corner protector body 1, wherein the corner protector body 1 is a double-layer wall structure and a cavity 109 is arranged between the double-layer walls, a buffer protection groove 101 is arranged on the inner side of the corner protector body 1, an inner concave hole 102 is arranged on the inner wall of the buffer protection groove 101, and an outer concave hole 103 is arranged on the outer wall of the corner protector body 1, wherein the inner concave hole 102 and the outer concave hole 103 are arranged opposite to each other, and the corner protector body 1 with a double-layer wall buffer structure is made of environmentally friendly flame-retardant tough material, which can obtain the buffering performance required for packaging and solve the problem that the foam cannot pass the environmental protection test. ; It can solve the problem of foam brittleness and fragmentation when encountering heavy products; it can solve the risk problem of foam being flammable and prone to fire; it can solve the geographical limitation problem of foam being large in volume and light in texture and inconvenient to transport over long distances; it can solve the problem that single-wall plastic corner protectors do not have a buffering function. The arrangement of inner concave holes 102 and outer concave holes 103 and reinforcing ribs 1 107 and ribs 2 108 on the inner and outer walls of the buffer corner protector can greatly increase the strength of the corner protector body 1, thereby reducing the wall thickness, reducing the product weight, greatly saving materials, and reducing packaging costs; the arrangement of the soft material 2 solves the current problem of surface hardness of plastic corner protectors.
[0038] As a specific technical solution of this embodiment, the positions of the inner concave hole 102 and the outer concave hole 103 correspond to each other, and the bottom surface distance can be adjusted as needed, and the minimum can be reduced to 0mm. The inner concave hole 102 and the outer concave hole 103 can play the role of supporting the inner and outer walls; refer to Figure 5 The distance between the bottom surfaces of the inner concave hole 102 and the outer concave hole 103 is very small, or they fit together or are connected as one. When the bottom surfaces of the inner concave hole 102 and the outer concave hole 103 contact each other, they can play a role of partially supporting the inner and outer double-layer walls, thereby increasing the strength of the corner protector body 1. To achieve the same protection effect, the structural setting of the inner and outer concave holes 102 and 103 can reduce the wall thickness, save materials, and reduce manufacturing costs. Increasing the thickness of the inner and outer double-layer corner protectors can increase the strength of the corner protector body 1 to cope with products of various weights on the market.
[0039] As a specific technical solution of this embodiment, the buffer protection groove 101 is provided with an inner vertex corner 104 inside, and the corner protection body 1 is provided with an outer vertex corner 105 outside. The inner concave hole 102 is close to the inner vertex corner 104, and the outer concave hole 103 is close to the outer vertex corner 105. One corner of the inner concave hole 102 protrudes into the cavity 109 to form a buffer corner 106. The buffer corner 106 is located near the inner vertex corner 104 and the protrusion distance of the buffer corner 106 into the cavity 109 is greater than the inner vertex corner 104, which can effectively protect the protected product 3; one side wall of the outer concave hole 103 extends near the outer vertex corner 105 to form a buffer claw 1031, and the buffer claw 1031 is located near the outer vertex corner 105 and the distance extending from the buffer claw 1031 to the outer vertex corner 105 is greater than the inner vertex corner 104, which can effectively resist the external impact force F from the vicinity of the outer vertex corner 105, thereby effectively protecting the protected product 3; refer to Figure 5 In this embodiment, the buffer protection groove 101 and the corner protection body 1 are both triangular, and the outer concave holes 103 on the three outer walls of the corner protection body 1 are close to the outer corner 105. In this way, when the outer corner 105 of the corner protection body 1 touches the ground, the force direction is referred to Figure 5 In the direction of the arrow F in the figure, a buffering is first performed, and then the buffer claws 1031 formed by the walls of the three outer concave holes 103 are reached. Because the structure of the outer concave holes 103 has a reinforcing effect, and the wall thickness direction of the buffer claws 1031 is in the direction of the external impact force F, the original wall force is changed to the wall thickness direction, which greatly enhances the force strength. The inner concave hole 102 on the inner wall of the buffer protection groove 101 is close to the inner top corner 104. The three inner concave holes 102 on the three inner walls of the buffer protection groove 101 protrude into the cavity 109 to form a buffer corner 106. When the outer top corner 105 of the corner protection body 1 is deformed by the external impact force F and exceeds the rebound force of the outer wall and the impedance force of the outer concave hole 103, the buffer corner 106 can still resist the external impact force, further protecting the product from external impact.
[0040] As a specific technical solution of this embodiment, the inner recessed hole 102 and the outer recessed hole 103 are both blind holes, countersunk holes or through holes. When the inner recessed hole 102 and the outer recessed hole 103 are fitted together or connected into one body to form a blind hole or a through hole, the inner recessed hole 102 and the outer recessed hole 103 can support and strengthen the inner and outer walls; when the inner recessed hole 102 and the outer recessed hole 103 are countersunk holes, the distance between the bottom surfaces of the inner recessed hole 102 and the outer recessed hole 103 can be adjusted as needed to increase the cushioning performance or increase the supporting strength so as to obtain matching cushioning and strength effects. According to the need to adjust the cushioning performance and the overall strength, the inner recessed hole 102 and the outer recessed hole 103 can also be staggered with each other, and the hole walls of the inner recessed hole 102 and the outer recessed hole 103 can still have a good supporting effect on the inner and outer double-layer walls on both sides of the cavity 109, which can further increase the matching options of cushioning performance and overall strength.
[0041] As a specific technical solution of the present embodiment, a reinforcing rib 107 is provided on the inner wall of the buffer protection groove 101, and a buffer groove 1071 is further provided on the inner wall of the buffer protection groove 101 on both sides of the reinforcing rib 107, the reinforcing ribs 107 on the two adjacent inner walls of the buffer protection groove 101 are connected as one, a reinforcing rib 108 is provided on the outer wall of the corner protection body 1, and a buffer groove 1081 is further provided on the outer wall of the corner protection body 1 on both sides of the reinforcing rib 108, the reinforcing rib 108 on the two adjacent inner walls of the corner protection body 1 is connected as one, the cooperation of the reinforcing rib 107, the reinforcing rib 108, the buffer groove 1071 and the buffer groove 1081 can produce a good planar reinforcement effect on the inner wall surface of the buffer protection groove 101 and the outer wall surface of the corner protection body 1, so that the same effect can be achieved, the wall thickness can be made much thinner, and at the same time the product can be softened, and materials can be saved and the manufacturing cost can be reduced.
[0042] As a specific technical solution of this embodiment, the inner wall of the buffer protection groove 101 is covered, encapsulated or polymerized with a layer of soft material 2. The soft material 2 is soft glue, EVA, rubber or other materials with equivalent effects, which can ensure that the buffer protection groove 101 will not scratch the contact surface between the protected product 3 and the buffer protection groove 101.
[0043] As a specific technical solution of this embodiment, the corner guard body 1 is made of tough material, which can be environmentally friendly plastic or a metal sheet with high elasticity. The outer wall formed by the tough material deforms inward when impacted by external force, and the reaction force offsets the impact force to achieve a buffering effect.
[0044] As a specific technical solution of this embodiment, the buffer protection groove 101 is one of triangular, L-shaped or rectangular, and the inner concave hole 102 and the outer concave hole 103 are one of square, circular, and elliptical. When the buffer protection groove 101 is triangular, it can protect products with triangular corners. When the buffer protection groove 101 is L-shaped, it can protect products with L-shaped corners. When the buffer protection groove 101 is rectangular, it can be used as a protective cover to protect the product on all sides.
[0045] To sum up, the double-layer structure buffer corner guard adopts environmentally friendly flame-retardant tough material to make the corner guard body 1 with a double-layer wall buffer structure, which can obtain the buffering performance required for packaging and solve the problem that the foam cannot pass the environmental protection test; it can solve the problem that the foam is brittle and breaks when encountering heavy products; it can solve the risk of foam being flammable and prone to fire; it can solve the geographical limitation problem that the foam is large in volume and light in texture and is inconvenient to transport over long distances; it can solve the problem that the single-wall plastic corner guard does not have a buffering function; the arrangement of recessed holes and reinforcing ribs on the inner and outer walls of the buffer corner guard can greatly increase the strength of the corner guard body 1, thereby reducing the wall thickness, reducing the product weight, greatly saving materials, and reducing packaging costs; the arrangement of the soft material 2 solves the current problem of the surface hardness of plastic corner guards.
