Abstract
The invention improves structure of screen supporter for fixing projector TV screen on case body. The structure of screen supporter reduces cost for fabricating back projector TV set. The invention also discloses spiral groove and guiding groove for forming screen supporter integrally. When screen supporter is made through NC process, only one procedure, one clamp or one die is needed for forming product in one piece so as to save cost for preparing screen supporter.
Description
Technical field
The present invention relates to the invention of relevant projection TV set, specifically is to have improved at the fixing screen mount structure of projection TV set screen of projection TV set body cabinet, can reduce the screen mount of the rear-projection TV set of manufacturing cost.
Background technology
Recently, along with the variation of reflection medium and the development of industry, more and more big to having big picture image display apparatus demand.The cathode ray tube that is used for traditional image display apparatus television receiver picture for the maximization of picture is limited by the maximization making of cathode ray tube self, so has the limitation of maximization.
For overcoming this limitation, and develop as the device of the picture that can obtain maximizing and practical to be exactly systems such as LCD (liquid crystal display) the projection TV of use microcomputer display unit and LCD projecting apparatus.As shown in Figure 1, LCD projection TV comprises as the lower part and constituting: the light engine (20) that is made of various parts; The engine that is installed in above-mentioned light engine (20) carries support (30); Be arranged on the basic framework (40) that above-mentioned engine carries support (30); Be arranged on above-mentioned basic framework (40) top, being provided with will be from the portrait of the projection lens projection bonnet (70) to the speculum (60) of screen (50) reflection.
And, above-mentioned screen (50) is fixed on the forward surface portion of body cabinet (10) by supporting bracket (80), as shown in Figure 2, above-mentioned supporting bracket (80) has laterally rectangular rectangle sheet material, with the screwed hole (82) of predetermined distance formation in order to be threaded, and,, other at above-mentioned screwed hole (82) for easy to assembly, with predetermined distance, formed bullport (84).
Therefore, when connecting above-mentioned supporting bracket (80) and body cabinet (10), at first, allow above-mentioned bullport (84), assemble in advance facing to the inboard guiding boss (not shown) that forms of body cabinet (10).The above-mentioned guiding boss (not shown) if bullport aligns, the screwed hole (82) of supporting bracket (80) be just to the thread bush (not shown) of upper body cabinet (10), at this moment, connects above-mentioned screwed hole (82) and screw rod (86) makes up.
But, because above-mentioned supporting bracket (80) is generally by the NC processing, and the screwed hole (82) of above-mentioned supporting bracket (80) and bullport (84) are separated from each other, so add man-hour, need be through twice operation, exist the production costs that increases mould and production to take and design complicated problems.
Summary of the invention
The object of the invention provides the screen mount that has improved the screen mount structure, can reduce the rear-projection TV set of manufacturing cost.
The objective of the invention is to be achieved through the following technical solutions:
The screen mount of rear-projection TV set, it is characterized in that connecting the threaded hole of body and, having formed the threaded hole and the bullport of connection in abutting connection with the bullport of threaded hole, lead screw hole site, at the fixing screen mount of projection TV screen of body cabinet by screw rod.
Advantage of the present invention and effect are:
As above finding, the screen mount of rear-projection TV set of the present invention, because whole helicla flute and the guiding groove that forms screen mount, during with NC processing and fabricating screen mount, can only be suitable for a program, anchor clamps or once production moulding of mould, so have the effect of saving production costs.

Fig. 1 is that the summary of general projection TV constitutes sectional drawing;
Fig. 2 is traditional projection TV screen mount schematic rear view;
Fig. 3 is the helicla flute of projection TV screen mount of the present invention and the expansion front elevation of guiding groove;
Fig. 4 is the expansion front elevation of the other embodiment of projection TV screen mount of the present invention.
The symbol description of drawing critical piece
100: screen mount, 102: helicla flute, 104: guiding groove, 106: slideway.
Embodiment
With reference to accompanying drawing, describe an embodiment of the screen mount of rear-projection TV set in detail.
Fig. 3 is the helicla flute of projection TV screen mount of the present invention and the expansion front view of guiding groove.
Projection TV screen mount of the present invention having laterally rectangular rectangle sheet material, forms for bolted screwed hole (102) with predetermined distance, simultaneously, assembling for convenience, other at above-mentioned screwed hole (82), formed bullport (104) with predetermined distance.The above-mentioned threaded hole and the bullport that form are communicated with.
At this, formed " one " font slideway (106) between above-mentioned threaded hole and the bullport, above-mentioned threaded hole and bullport are connected mutually.
Therefore, when connecting above-mentioned supporting bracket (100) and projection TV body cabinet (10 :), at first, allow above-mentioned bullport (104), assemble in advance facing to the inboard guiding boss (not shown) that forms of body cabinet (10 :) with reference to Fig. 2 with reference to Fig. 2.The above-mentioned guiding boss (not shown) if bullport (104) aligns, the screwed hole (102) of screen mount (100) just can be to the thread bush (not shown) of upper body cabinet (10: with reference to Fig. 2), from this moment, connect above-mentioned screwed hole (102) and screw rod and make up.
Fig. 4 is the diagrammatic sketch of another one embodiment of the present invention.At the foregoing description,, above-mentioned threaded hole and bullport are connected mutually though between above-mentioned threaded hole and bullport, form " one " font slideway.But according to another one embodiment of the present invention, its formation is to connect threaded hole (202) circumference and bullport (204) circumference by straight line.
In addition, because other formations of present embodiment or effect are identical with previous embodiment, detailed.
Therefore, the screen mount of rear-projection TV set of the present invention because whole helicla flute and the guiding groove that forms above-mentioned screen mount, when NC processes above-mentioned screen mount, only can form with time processing.
