Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

The utility model provides a backplate assembly structure before large screen display, as shown in figure 1, 2, including plastic frame 1 and five metals backplate 2, the interior week of plastic frame 1 is equipped with backplate mounting groove 3, is equipped with a plurality of locating piece 4 in the backplate mounting groove 3, the protruding hot melting point 5 that forms that makes progress in the middle part of locating piece 4, the border of five metals backplate 2 is equipped with buckle closure 6 at the position that corresponds locating piece 4, has seted up through-hole 7 on the

buckle closure

6, 6 lids of buckle closure are closed on locating piece 4 when backplate mounting groove 3 is packed into to five metals backplate 2, hot melting point 5 on locating piece 4 is worn out from through-hole 7 on buckle closure 6 this moment.

In this embodiment, the plastic frame is rectangular, and the positioning blocks 4 are only disposed on three sides of the plastic frame 1, which are respectively a long side and two short sides. The positioning blocks 4 are uniformly arranged in the three backboard installing grooves 3 at intervals. The positioning blocks 4 are arranged on three sides, so that the hardware back plate 2 is guaranteed not to shake in all directions, the stability of the connecting structure is met, meanwhile, the machining process and the hot melting process of the fourth side are saved, and the production cost is effectively reduced.

In this embodiment, the number of the positioning blocks 4 is 20, the number of the thermal melting points 5 on each positioning block 4 is 2, the number of the corresponding fastening covers 6 on the hardware backboard 2 is 20, and the number of the through holes 7 on each fastening cover 6 is 2. Plastic frame 1 sets up a stopper 8 respectively in the both sides of every locating piece 4, and after five metals backplate 2 packed into plastic frame 1 promptly, stopper 8 was located the both sides of buckle closure 6 to control about restricting five metals backplate 2, thereby make five metals backplate 2 more firm with being connected of plastic frame 1.

In addition, the plastic frame 1 and the hardware backboard 2 in the existing scheme are combined together by adopting an in-mold injection molding process, and the light guide plate and the reflective film also need to be put in advance, so that the light guide plate and the reflective film are easy to damage. This embodiment has improved to this problem, the tank bottom of backplate mounting groove 3 on a pair of edges of plastic frame 1 inwards extends and forms protruding edge 10, pack into backplate mounting groove 3 from the back of plastic backplate 1 when five metals backplate 2, buckle closure 6 lock is on locating piece 4, protruding edge 10, locating piece 4 and five metals backplate 2 enclose the back that forms back-off recess 9 (as shown in fig. 4, 5) again in the front of plastic backplate 1, the width of protruding edge 10 is 2.4mm, accessible deformation mode such as light guide plate, reflectance coating inserts the back-off recess 9 on both sides. The installation of light guide plate, reflectance coating is more convenient for setting up of back-off recess 9, and not fragile light guide plate and reflectance coating, because the width of back-off recess 9 sets up to comparatively suitable 2.4mm, makes narrower and more reliable that plastic frame 1 was done.

The present case combines five metals backplate 2 and plastic frame 1 together through the mode of hot melt, and when the product recovery, five metals backplate 2 can be dismantled, separable recycle with plastic frame 1, not only can practice thrift manufacturing cost but also be favorable to the environmental protection.

The assembling method comprises the following specific steps:

s1, preparing a plastic frame 1 and a hardware back plate 2: the plastic frame 1 and the hardware backboard 2 are respectively manufactured and molded by respective dies;

s2, assembling and fastening, namely, installing the hardware back plate 2 into the plastic frame 1, and attaching the fastening cover 6 to the positioning block 4 to ensure that the hot melting points 5 on the positioning block 4 extend out of the through holes 7;

s3, heating and hot melting: heating and melting the hot melting point 5 by using a hot melting tool, pressing down to form a mushroom head shape, fixing the hardware backboard 2 and the plastic frame 1, and forming an inverted groove 9 on a pair of edges of the plastic frame 1;

s4, mounting accessories: the light guide plate and the reflective film are inserted into the inverted grooves 9 at both sides of the plastic frame 1 in a bending deformation manner, thereby completing the whole assembly process.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the design of the present application, and all equivalent changes made according to the design key of the present application fall within the protection scope of the present application.
