Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

Referring to fig. 1-6, the present invention provides the following technical solutions: can improve novel light guide plate of light-emitting luminance, including optics level ya keli board 1, the leaded light point 2 has been seted up to optics level ya keli board 1's table wall, and four edges of optics level ya keli board 1 all are provided with fixed buckle 14, install fixed buckle 14 back, can produce certain gap between the mounting structure of light guide plate and user equipment, when optics level ya keli board 1 thermal expansion is good, the position of fixed buckle 14 is unchangeable, optics level ya keli board 1 extrudes the flexible fastener 4 of inlayer in the fixed buckle 14, borrow this make the inflation of optics level ya keli board 1 more even, with this luminous inhomogeneous condition after having avoided thermal expansion, fixed buckle 14 includes outer rigidity fastener 3 and inlayer flexible fastener 4, inlayer flexible fastener 4 adopts flexible material, can take place the deformation of certain degree after the extrusion, and possess certain extrusion force to the edge of optics level ya keli board 1 at normal atmospheric temperature promptly, and the inner layer flexible clamping piece 4 is positioned at the inner side of the outer layer rigid clamping piece 3.

Furthermore, the inside of optics level acrylic plate 1 four corners all has seted up perforation 13, and the internally mounted of perforation 13 has a mounting 12, and the thickness of mounting 12 is the same with the thickness of optics level acrylic plate 1 and two flange pieces 10, packs it into from the inside of one of them flange piece 10 when using to make it run through perforation 13 and another flange piece 10.

Furthermore, the fixing member 12 comprises a rigid filling block 5 and a flexible filling ring 6, the rigid filling block 5 is located inside the flexible filling ring 6, the flexible filling ring 6 and the inner flexible clip 4 are made of the same material, and the flexible material can adapt to the expansion and contraction of the through hole 13 at different temperatures.

Specifically, the flange blocks 10 are symmetrically installed on two sides of the fixing buckle 14, the fixing covers 11 are symmetrically installed on two sides of the fixing piece 12, the width of each fixing cover 11 is larger than the diameter of each through hole 13, and the fixing covers 11 are installed at two ends of the fixing piece 12 to prevent the fixing piece 12 from falling off.

It is worth to say that the inner wall of the fixing buckle 14 is provided with the inner caulking groove 9, the surface wall of the optical-level acrylic plate 1 is provided with the protective film 7, the protective film 7 and the surface wall of the optical-level acrylic plate 1 have the same structure, but the size of the protective film is smaller, the whole protective film is in an equal-proportion reduction shape, the edge of the protective film 7 is positioned on the surface wall of the optical-level acrylic plate 1 after being pasted, but not positioned on the same plane with the side wall of the optical-level acrylic plate 1, and therefore the situation that the protective film 7 is warped after the side wall of the optical-level acrylic plate 1 is touched and rubbed is avoided.

Further, the edge of protection film 7 is provided with the protrusion and tears limit 8, and the protrusion tears limit 8 and embedded groove 9 phase-matches, pastes protection film 7 back, tears limit 8 with the protrusion at its edge and buckles and fill in embedded groove 9, avoids the protrusion to tear limit 8 and appear sticking up the limit.

The working principle and the using process of the utility model are as follows: when the utility model is used, the light guide point 2 is carved on the surface wall of the optical-level acrylic plate 1 by adopting laser, then the protective film 7 is stuck on the surface wall of the optical-level acrylic plate 1, because the protective film 7 and the surface wall of the optical-level acrylic plate 1 have the same structure, but the size of the protective film 7 is smaller, the edge of the protective film 7 can be positioned on the surface wall of the optical-level acrylic plate 1, when the side wall of the optical-level acrylic plate 1 is rubbed, the edge of the protective film 7 cannot be affected, so that the situation that the protective film 7 has a raised edge is avoided, the fixing buckles 14 are installed at four corners of the optical-level acrylic plate 1, then the fixing piece 12 is inserted into the through hole 13 at the corner of the optical-level acrylic plate 1 from the edge blocking block 10, and is fixed from two sides of the fixing piece 12 by using the fixing covers 11, so that the fixing buckles 14 are installed at the corners of the optical-level acrylic plate 1, then fix optics level ya keli board 1 on using equipment, because fixed buckle 14 is in optics level ya keli board 1's edge, can have a gap between optics level ya keli board 1 and the installation equipment, when the operational environment of light guide plate appears and heaies up and lead to optics level ya keli board 1 whole extension, optics level ya keli board 1 can extrude the flexible fastener 4 of the inlayer in the fixed buckle 14, and because the gap that exists between optics level ya keli board 1 and the installation equipment provides the space for the extension, consequently avoided optics level ya keli board 1 to expand inhomogeneous condition, and when the low temperature leads to optics level ya keli board 1 to shrink, the extrusion effect of the flexible fastener 4 of inlayer to optics level ya keli board 1 can avoid optics level ya keli board 1 to appear becoming flexible.
