[0025] Reference Figure 1-4 As shown, the utility model provides a technical solution: a bending-resistant Mylar sheet, comprising a substrate 1.
[0026] The following is a detailed description of its overall specific settings and functions.
[0027] In this embodiment, the sidewalls of the substrate 1 are provided with a plurality of reinforcement holes 6, each having an equilateral triangular cross-section. The surface of the substrate 1 is provided with a plurality of reinforcement grooves 7, each having a triangular cross-section. The equilateral triangular reinforcement holes 6 provided on the sidewalls of the substrate 1 enhance the substrate 1's resistance to longitudinal bending, while the reinforcement grooves 7 provided on the upper surface improve the substrate 1's resistance to transverse bending. The staggered vertical arrangement of the reinforcement grooves 7 and the reinforcement holes 6 enhances the overall resistance to bending during use, providing increased durability.
[0028] Specifically, the inner side of the reinforcement hole 6 is slidably connected with a reinforcement rib 3, and the reinforcement rib 3 is a triangular prism structure. By providing the reinforcement rib 3, the bending resistance of the substrate 1 during longitudinal bending is further improved. Auxiliary heads 5 are fixedly connected to both ends of the reinforcement rib 3, and the auxiliary heads 5 have a step structure. The provision of the auxiliary heads 5 improves the efficiency of inserting the reinforcement rib 3 into the interior of the substrate 1. Several rubber blocks 4 are evenly glued to the side walls of the reinforcement rib 3, and the rubber blocks 4 have a spherical structure. The provision of the rubber blocks 4 increases the resistance to the pulling of the reinforcement rib 3 when inserted into the inner side of the reinforcement hole 6, and further improves the stability of the installation and use of the reinforcement rib 3. The upper surface of the substrate 1 is glued with a composite board 2. By pasting the composite board 2 on the substrate 1, the thickness of the substrate 1 can be increased and the strength of the substrate 1 can be improved. Several ridges 8 are provided on the lower surface of the composite board 2, and the size of the ridges 8 is adapted to the size of the reinforcement groove 7. Sliding the convex strip 8 into the inner side of the reinforcing groove 7 not only improves the tightness of the adhesion between the base plate 1 and the composite plate 2, but also further improves the bending resistance of the base plate 1 when it is bent.
[0029] Working principle: by setting the reinforcement hole 6 of equilateral triangle structure on the side wall of the base plate 1, the bending resistance of the base plate 1 when subjected to longitudinal bending is enhanced, and a number of reinforcement grooves 7 are set on the upper surface to improve the transverse bending resistance of the base plate 1 when bending. The reinforcement grooves 7 and the reinforcement holes 6 are staggered and arranged vertically, thereby improving the overall bending resistance of the base plate 1 during use, and improving the strength of the base plate 1. The reinforcement rib 3 is inserted into the inner side of the reinforcement hole 6. The setting of the auxiliary head 5 improves the efficiency of the reinforcement rib 3 inserted into the interior of the base plate 1, and the setting of the rubber block 4 increases the resistance of the reinforcement rib 3 to twitching when inserted into the inner side of the reinforcement hole 6, further improving the installation and use of the reinforcement rib 3. The stability of use is improved by setting the reinforcing ribs 3, which further improves the bending resistance of the substrate 1 when it is longitudinally bent. Glue is coated on the upper surface of the substrate 1, and the composite board 2 is pasted on the substrate 1. The use thickness of the substrate 1 can be increased, and the use strength of the substrate 1 can be improved. The convex strips 8 are slid into the inner side of the reinforcing grooves 7, which not only improves the tightness of the adhesion between the substrate 1 and the composite board 2, but also further improves the bending resistance of the substrate 1 when it is bent. By setting the above structure, the bending resistance effect of the Mylar sheet when it is used can be effectively improved, and the phenomenon of bending and cracking of the Mylar sheet during use can be avoided, thereby improving the use performance of the Mylar sheet and extending the service life of the Mylar sheet.
