Description
Technical field
The present invention relates to the connected element of a kind of LED giant-screen unit display screen, especially a kind of self-locking connection fastener.
Background technique
The LED big screen display screen is comprised of several unit display screen docking; Each unit display screen shows that by several unit module arrangement splicing forms.Along with developing of cultural industry, the multimedia display clearness technical requirements of display background is more and more higher, and there is the bottleneck problem of a structure " piece and installation " in existing LED big screen display screen always.After being connected between the out-of-flatness of unit display screen makes screen and shields, there is step shade phenomenon in display surface not in a plane, and step shade phenomenon causes occurring mosaic phenomenon.The blank screen gap, the blank screen mosaic affects the LED display effect.
At present, the connection between the unit display screen mainly is by at the unit display screen blind tapped hole of design and blind unthreaded hole, adopts screw thread locating stud and form loose-leaf binder or link that two module unit display screens are fixed together.Concrete, an end of screw thread locating stud is screwed into the blind tapped hole of a unit display screen, the other end inserts the blind unthreaded hole of another unit display screen, comes the unit display screen of two interconnection of snapping with form loose-leaf binder again.Locating stud and form loose-leaf binder be respectively action successively, finishes the splicing of unit display screen.Perhaps ignore the location, directly adopt form loose-leaf binder to come snapping.But there is thread pitch thread engagement in itself, and locating stud easily is offset, and Location accuracy is not high, has the problem of the inaccurate problem in location and difficult assembling; After the screw thread locating stud is screwed into, improve Location accuracy, will dwindle the gap of locating stud polished rod part and blind unthreaded hole, dwindle the problem that difficult assembling can be brought in the gap; Satisfy and be convenient to assembling, the gap that will amplify both, the problem that can bring again the location inaccurate is amplified in the gap; Form restricting relation between the two.The 2nd, locating stud is to be rigidly connected after being screwed into the unit display screen, can not axial stretching, can not from giant-screen, dismantle arbitrarily next unit display screen, and can not solve the problem that the displaying scene quick-mounting unloads.The 3rd, do not lock a little behind the form loose-leaf binder snapping, there is to deviate from the unreliable phenomenon of snapping.If adopt separately form loose-leaf binder to connect, although can realize quick loading and unloading, the blank screen gap of display screen, the blank screen mosaic, phenomenon is serious, affects the display effect of LED giant-screen.
