An aspect according to the utility model; A kind of TFT LCD framework is provided; Framework is a square shape, is made up of first framing component, second framing component and two strip members, and first framing component is " recessed " font; Second framing component is " protruding " font; The first framing component intermediate recess portion both sides are provided with two projection limits, and the second framing component center protrusion portion both sides are provided with the two depression limits that equate with said projection hem width degree, and the degree of depth of the first framing component intermediate recess portion equates with the height of the second framing component center protrusion portion.

In some embodiments, the strip member cross-sectional width equates with projection limit and depression limit difference width.Make between strip member and first framing component and second framing component and strip member be connected more firm.

In some embodiments, the strip member cross-sectional width is less than projection limit and depression hem width degree.Dwindle the strip member size, when guaranteeing that framework connects, further reduced the materials cost.

In some embodiments, be provided with pilot hole near the framework inner side on first framing component, second framing component and the two strip member surfaces.Pilot hole on first framing component and second framing component and the strip member is sheathed on the register pin of weld jig; Isolated first framing component and second framing component and strip member are positioned on the weld jig; Be difficult for during welding taking place loosening and skew, make that welding is tightr.

In some embodiments, first framing component, second framing component and two strip members are bonded together it through riveted, welding or welding.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe in detail explanation.

Embodiment one

Fig. 1 to Fig. 3 has schematically shown the TFTLCD framework according to an embodiment of the utility model, comprises first framing component, 100, the second framing components 200 and two strip members 300.

As shown in Figure 2, first framing component 100 is " recessed " font, comprises two projection limits 103,105 of first base 101 and depressed part 107 both sides.

As shown in Figure 3; Second framing component 200 is " protruding " font; Comprise second base 201 that equates with first base, 101 width; And 203,205, the first bases, two depression limits, the 101 depressed part degree of depth that jut 207 both sides equate with two projection limits, 103,105 width equate with second base, 201 jut height.

Two strip members, 300 structures are identical, and size equates.First base 101 equates that with second base, 201 width two projection limits 103,105 equate that with the width on two depression limits 203,205 first framing component, 100 depressed parts, 107 width equate with second framing component, 200 juts, 207 width.

In this embodiment, first framing component 100 and second framing component 200 are the minor face of square shape framework, and two strip members 300 are the long limit of square shape framework.

First framing component, 100, the second framing components 200 and two strip members, 300 surfaces are gone up and are respectively equipped with pilot hole 400 near the framework inner side.During welding, the pilot hole 400 on the member is sheathed on the register pin on the welding fixture, and workpiece is fixed, and can not squint, and has guaranteed the accuracy of welding.

Fig. 4 has schematically shown the embodiment that the utility model manufacturing is drawn materials.As shown in Figure 4, with pluralize a block square cross 500 of whole piece metal material punching out.Each block square cross 500 has comprised one first framing component 100 and one second framing component 200.Again another metal material punching out is become a negative strip square cross 600, each strip square cross 600 comprises two strip members 300.

Fig. 5 has schematically shown the welding synoptic diagram of the utility model.As shown in Figure 5, isolate first framing component 100 and second framing component 200 from block square cross 500, isolate two strip members 300 from strip square cross 600.Pilot hole 400 on first framing component 100, second framing component 200 and two strip members 300 is sheathed on the register pin 700 on the welding fixture; And make win framing component 100, second framing component 200 and two strip members 300 be bonded into one, form the square shape frame structure.Be sheathed on through pilot hole 400 on the register pin 700 of welding fixture, make that first framing component 100 and second framing component 200 can not take place loosening or skew in the welding process, improved the precision of welding.Wherein, the juncture of 300 of first framing component 100, second framing component 200 and two strip members is riveted, welding or welding.Embodiment 2
