When sealed, splicing lock 3 is moved along the strip through hole 24 on the installation sheet 20 of fixed seat 2, according to required splicing angle
The position of degree regulation splicing lock 3, exemplified by splicing angle for 12 °, splicing is moved in the position for being 12 ° to splicing angle index 200
Lock 3, when the hoodle 380 of elastic positioning member 38 is partially housed in location indentations 28 and sends corresponding sound, it can be determined that spells
The regulation face that the alignment of lock 3 angle of inclination is 12 ° is connect, now the second shaft part 308 of the locking bar 300 of splicing lock 3 is located at positioning through hole
In 26.The projection 304 of locking bar 300 is axially pressed to the left, and the mortise lock portion 34 of locking bar 300 is inserted to the lock-joining part 42 in regulation face 40
In, then pivot protrusion 304 and mortise lock portion 34 is partially housed in detent 402, now, Mosaic face 320 with regulation face
40 fittings, the first location division 322 and the second location division 400 coordinate, and the first shaft part 306 of locking bar 300 is positioned at positioning through hole 26.
Although the elastic force of elastic component 302 can produce thrust to the right to projection 304 and play certain tensioning function, its in order to
Moving left and right and rotating for locking bar 300 is realized, the elastic force of elastic component 302 can not be excessive, i.e. Mosaic face 320 and regulation face 40 may
Separate in the lateral direction；Therefore, tighten part 362 by what rotation tightened component 36, make to tighten part 362 move right and
The projection 304 of locking bar 300 is supported, further to tense the split of Mosaic face 320 and regulation face 40, is shown so as to complete two LED
The accurate splicing of screen 5, now the splicing angle of two LED displays 5 is 12 °, and stitching portion is set relative to display surface depression.
During unblock, rotation tightens part 362, makes to tighten part 362 and is moved to the left and cancels the projection 304 for supporting locking bar 300, so
Axially pressing locking bar 300 makes mortise lock portion 34 be separated with detent 402 to the left afterwards, and rotating rod lock 300, makes mortise lock portion 34 and lock
Socket part 42 is aligned and departs from separation from lock-joining part 42, and now Mosaic face 320 separates with regulation face 40, and the second shaft part 308
In positioning through hole 26.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the scope of the invention, it is every at this
Under the inventive concept of invention, the equivalent structure transformation made using description of the invention and accompanying drawing content, or directly/use indirectly
It is included in other related technical areas in the scope of patent protection of the present invention.
