Background technology

Quick atrophy along with traditional C RT TV market, it with the liquid crystal TV set main flow that the panel TV set of representative becomes TV market, yet the liquid crystal display screen overwhelming majority that now homemade liquid crystal TV set adopts is from Japan, national import such as Korea S, whole television set industry is under one's control, appearance along with " national electronics and information industry development planning ", the production domesticization of plane Display Technique has risen to national strategy, the structural design how rationally to utilize liquid crystal display screen to carry out the liquid crystal TV set complete machine fully seems particularly important, large-sized liquid crystal TV set generally all is by the switching part movement circuit plate to be connected on the liquid crystal display screen backboard, yet since the liquid crystal display screen of each liquid crystal display screen producer often the version difference is very big, select for use the plurality of liquid crystals screen to bring very large difficulty simultaneously for liquid crystal television set complete machine producer, traditional LCD TV machine core erecting device is for guaranteeing safety, several safe distances to tens millimeters will be arranged between movement circuit plate and the liquid crystal display screen backboard, and the liquid crystal display screen backboard generally adopts steel plate to make, for guaranteeing that the convex closure on the liquid crystal display screen backboard does not split, the convex closure height can only be done four millimeter, generally be on the liquid crystal display screen backboard, to adhere to a bigger monoblock steel plate earlier or adhere to a plurality of strip parts, the movement circuit plate is fixed on integral plate or the strip part more then, adhere to the liquid crystal TV set movement circuit plate of a plurality of strip parts back schematic diagram such as Fig. 1 are installed, this LCD TV machine core erecting device is not only installed dumb, be not easy to carry out standardization, General design, and spare part outside measurement is big and complicated, and cost is very high.

The utility model content

The purpose of this utility model is to overcome the shortcoming that present LCD TV machine core erecting device need adhere to steel plate or strip part, and a kind of LCD TV machine core erecting device is provided.

The utility model solves its technical problem, the technical scheme that adopts is, LCD TV machine core erecting device, comprise screw, liquid crystal display screen and movement circuit plate, liquid crystal display screen comprises the liquid crystal display screen backboard, possesses convex closure on the described liquid crystal display screen backboard, described movement circuit plate is provided with installing hole, it is characterized in that described convex closure is corresponding with the installing hole on the movement circuit plate, convex closure is provided with screw hole, also comprise the support that adapts with convex closure, described support is installed on the convex closure, and support is provided with through hole, and the through hole that screw passes installing hole and support is fixed on the screw hole of convex closure.

Concrete, described convex closure also comprises draw-in groove, and support also comprises grab, and described draw-in groove and grab adapt; Described convex closure also comprises location hole, and support also comprises alignment pin, and described alignment pin and location hole adapt.

Further, described support is a plastic part.

The beneficial effects of the utility model are, convex closure on the liquid crystal display screen backboard is corresponding with the installing hole on the movement circuit plate, only utilize some small racks can finish being connected of movement circuit plate and liquid crystal display screen backboard, save cost, and because screw directly is connected the movement circuit plate with convex closure on the liquid crystal display screen backboard, more firm, utilize support also can reach the interval of a few to tens of millimeters between movement circuit plate and the liquid crystal display screen backboard, because the adding of draw-in groove and grab, make support simple and convenient with being connected of convex closure, and increase location hole and alignment pin can make support more firm with being connected of convex closure, support adopts the then convenient making of plastic part and saves cost, the interval between also easier adjusting movement circuit plate and the liquid crystal display screen backboard.

Embodiment

Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.

LCD TV machine core erecting device of the present utility model by be arranged on the liquid crystal display screen backboard 1 with movement circuit plate 3 on installing hole 13 corresponding convex closures 11, support 4 and the screw 8 that adapts with convex closure 11 form, wherein, convex closure 11 is provided with screw hole 5, support 4 is installed on the convex closure 11, support 4 is provided with through hole 9, and the through hole 9 that screw 8 passes installing hole 13 and support 4 is fixed on the screw hole 5 of convex closure 11.

Embodiment

This routine convex closure 11 also comprises draw-in groove 6 and location hole 7, support also comprises grab 10 and alignment pin 12, wherein, draw-in groove 6 adapts with grab 10, alignment pin 12 adapts with location hole 7, its liquid crystal TV set movement circuit plate is installed back schematic diagram such as Fig. 2, certain installing hole of movement circuit board and support and the corresponding schematic diagram of convex closure such as Fig. 3 when not using screw, certain installing hole of movement circuit plate and schematic diagram such as Fig. 4 after support and convex closure link to each other by screw, the structural representation of convex closure such as Fig. 5, the structural representation of support such as Fig. 6,7.

During installation, at first the alignment pin on the support 4 12 is inserted in advance in the location hole 7 on the convex closure 11, exert oneself slightly downwards, the grab 10 that is about on the support 4 is installed on the draw-in groove 6 of convex closure 11, on support 4, place movement circuit board 3 then, be fastened on the screw hole 5 of convex closure 11 after passing installing hole 13 on the movement circuit plate 3 and the through hole 9 on the support 4 with screw 8 at last, because convex closure 11 is set directly on the liquid crystal display screen backboard 1, therefore utilize screw 8 directly movement circuit plate 3 to be connected with convex closure 11 on the liquid crystal display screen backboard 1 like this, be equivalent to directly movement circuit plate 3 be fixedlyed connected with liquid crystal display screen backboard 1, also can be better on the steadiness than prior art, support 4 adopts plastic part, save cost and convenient the making, not only reached the interval of a few to tens of millimeters between movement circuit plate and the liquid crystal display screen backboard, the interval between also easier adjusting movement circuit plate and the liquid crystal display screen backboard.
