As shown in the accompanying drawings: 1 modular corner protector, 101 corner protector body, 1011 notch, 1012 buffering groove, 102 first convex platform, 103 second convex platform, 104 first anti-slip convex rib, 105 second anti-slip convex rib, 106 third anti-slip convex rib, 107 through hole, 108 hexagonal hole, 109 circular dodge hole, 2 screw, 3 nut, 4 groove.
The technical scheme of the invention is further described clearly and detailedly hereinafter with reference to drawings. Obviously, only partial embodiments of the invention are shown and the actual structure is not limited thereto. All other embodiments, which can be obtained by those skilled in the art without making any creative effort based on the embodiments in the present invention, shall all fall within the protective scope of the invention.
Embodiment 1, with reference to
The modular corner protector 1 includes a corner protector body 101 and a first convex platform 102 and second convex platform 103 provided on two sides of the corner protector body 101 respectively, and two sides of the corner protector body 101 are provided with first anti-slip convex ribs 104.
As a preferred technical solution of the invention, the corner protector body 101 is integrally molded with the first convex platform 102 and second convex platform 103 on both sides thereof, which can be formed by blow molding or mold shaping. After the modular corner protector 1 is molded, a closed cavity is formed inside thereof for cushioning the striking force.
As a preferred technical solution of the invention, the corner protector body 101 is square as a whole, and length and width dimensions of the corner protector body 101 are the same; this design not only saves processing materials and maximizes protection of the product, but also facilitates combination of two modular corner protectors 1 and ensures the appearance after combination.
As a specific technical solution of the embodiment, second anti-slip convex ribs 105 are provided on edges of back side of the first convex platform 102 and second convex platform 103; arrangement of second anti-slip convex ribs 105 increases friction between the modular corner protector 1 and outer packaging material, reduces shaking, and ensures stability of the modular corner protector 1. At the same time, a cushioning space will be formed in interior of second anti-slip convex ribs 105, which further ensures cushioning and protection effect of the modular corner protector 1.
As a specific technical solution of the embodiment, third anti-slip convex ribs 106 are provided on edges of two sides of the corner protector body 101, and both ends of the first anti-slip convex ribs 104 and third anti-slip convex ribs 106 extend to the second anti-slip convex ribs 105; the third anti-slip convex ribs 106 and first anti-slip convex ribs 104 serve the same purpose, both of which increase friction with the product, and when the product is clamped to inside of the groove 4, the first anti-slip convex ribs 104 and third anti-slip convex ribs 106 contact with the product, which are not smooth planes, ensuring stability of the modular corner protectors 1 and product assembly, and at the same time, due to hollowing arrangement of the first anti-slip convex ribs 104 and second anti-slip convex ribs 105, buffering space will be shaped between inner wall of the groove 4 and the product, which further reduces collision damage to the product.
As a specific technical solution of the embodiment, interior of the corner protector body 101 is provided with through holes 107 for installing screws 2, both ends of the through holes 107 are provided with hexagonal holes 108, and the hexagonal holes 108 are used for installing screw heads or nuts 3; circular dodge holes 109 are provided at one end of the hexagonal holes 108 away from the through holes 107; when used, two modular corner protectors 1 are arranged opposite to each other, firstly put the nuts 3 into hexagonal holes 108 of one modular corner protector 1, use the screws 2 to pass through circular dodge holes 109 of the other modular corner protector 1 and screwed into the nuts 3, partially screwed into the nut 3 can be efficient; corner of the product is stuck by two initially combined modular corner protectors 1 through the groove 4, continuing to screw the screw 2 to make two modular corner protectors 1 more close to and fasten the product firmly, in the screw head 2 is provided with an internal hexagonal groove, and the screw 2 can be screwed through the hexagon key.
As a specific technical solution of the embodiment, a notch 1011 is provided on one corner of the corner protector body 101. The notch 1011 is provided to reduce the amount of material to be processed for the modular corner protector 1, while facilitating clamping of the groove 4 to the product.
As a specific technical solution of the embodiment, buffering grooves 1012 with two ends extending to the first convex platform 102 and second convex platform 103 respectively are provided on two side edges of the corner protector body 1 away from the notch 1011. The arrangement of buffering grooves 1012 reduces the processing material and increase the friction between two side edges of the corner protector body 101 away from the notch 1011 and outer packaging material, which further ensures the stability of use.
As a specific technical solution of the embodiment, in the embodiment, thickness of the first convex platform 102 is smaller than the thickness of the second convex platform 103, and after symmetrically affixing two modular corner protectors 1 via the second convex platform 103, thickness of groove 4 between two modular corner protectors 1 is larger.
