In order to solve the problems of difficult and improper assembly of the light guide plate, the invention aims to provide a light guide plate fastener to accelerate the assembly efficiency of the light guide plate and improve the assembly quality.
The purpose of the invention is realized by the following technical scheme:
the utility model provides a light guide plate buckle spare, the installation end of light guide plate is located to the buckle spare, the buckle spare is including connecting face, top surface and circular arc curved surface, wherein, it is do to connect the face for buckle spare and light guide plate, just it coincides with the installation face of light guide plate to connect the face, the top surface is perpendicular with the installation face of light guide plate, the circular arc face certainly connect the face bottom to the periphery of top surface extension.
Preferably, the fastener and the light guide plate are integrally formed.
Preferably, the fastener is arranged along the bottom end of the middle part of the installation end of the light guide plate.
Preferably, the middle position of the joint of the arc surface and the connecting surface is provided with an arc notch, which is opposite to the top surface.
Preferably, the connecting surface is arc-shaped.
Preferably, the periphery of the top surface is arc-shaped.
Preferably, the top surface is an arc-shaped curved surface with the middle part protruding upwards.
Preferably, the outer contour of the fastener is in the shape of a half bowl.
The invention has the beneficial effects that:
the light guide plate fastener changes the wedge-shaped (trapezoid-shaped) light guide plate fastener into the arc-shaped fastener, and the arc-shaped fastener can change the wedge-shaped line contact into point contact, so that the contact area is reduced, the pressure is concentrated on one point, and the pressure intensity is increased, so that the light guide plate is assembled more quickly and more conveniently, the assembly difficulty is effectively reduced, the product assembly quality is improved, and the design reliability standard of the original trapezoid-shaped structure fastener is kept.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The utility model provides a light guide plate buckle spare, the installation end of light guide plate is located to the buckle spare, preferably, the middle part bottom setting of buckle spare along the installation end of light guide plate. As shown in fig. 3d, the fastening member includes a connecting surface 1, a top surface 2, and an arc curved surface 3, where the connecting surface 1 is the connecting surface of the fastening member and the light guide plate, the connecting surface 1 coincides with the mounting surface of the light guide plate, the top surface 2 is perpendicular to the mounting surface of the light guide plate, and the arc surface extends from the bottom of the connecting surface 1 to the periphery of the top surface 2.
Preferably, the fastener and the light guide plate are integrally formed.
And the middle position of the joint of the arc surface and the connecting surface 1 is provided with an arc notch 4 opposite to the top surface 2.
The connecting surface 1 is arc-shaped, and the periphery of the top surface 2 is arc-shaped.
Preferably, the top surface 2 corresponds to the arc notch 4 and is an arc-shaped curved surface with an upward convex middle part, and the connecting surface 1 is also an arc-shaped surface with a notch in the middle part.
As shown in fig. 3a to 3d and fig. 4, the outer contour of the locking member is in the shape of a half bowl.
As can be seen from fig. 4, the light guide plate fastener of the invention changes the wedge-shaped (trapezoid-shaped) light guide plate fastener into the arc-shaped fastener, and the arc-shaped fastener can change the wedge-shaped line contact into the point contact, thereby reducing the contact area, concentrating the pressure on one point, and increasing the pressure, so that the light guide plate can be assembled more rapidly and easily, the assembly difficulty is effectively reduced, the product assembly quality is improved, and the design reliability standard of the original ladder-shaped structure fastener is maintained.
