, to sum up by the cooperation of fixed block 7, tongue 3 and slot 4, solve in actual use that connector is complicated for operation, and
Connector occupies the segment space of sub-screen 1 when connecting sub-screen 1, affects the using effect of mosaic screen, connects simultaneously
Device is not easy to be attached the middle section of sub-screen 1, and 1 middle section of sub-screen is be easy to cause the problem of gap occur.Two
The phase backside of spring 14 is fixedly connected with the inner wall of 7 two sides of fixed block respectively.
Working principle: the seamless display device of the liquid crystal-spliced screen of the LCD when in use, when needing to splice sub-screen 1, makes
The tongue 3 of one 1 side of sub-screen is inserted into the slot 4 of another 1 side of sub-screen, so that simple concatenation forms a square
Shape main screen 2 is further fastenedly connected it by fixed block 7 in the junction of four sub-screens 1, inwardly squeezes rack gear manually
Bar 10, inwardly movement will drive the rotation of gear 12 to rack bar 10, and the rotation of gear 12 then will drive rack gear block 13 and be displaced outwardly, rack gear
Block 13 can squeeze spring 14, and fixed link 5 can be can smoothly enter into the cavity in fixed block 7, then release to rack bar 10
Extruding, under the action of 14 elastic force of spring push 13 inclined-plane of rack gear block rack-plate 17 and 5 inclined-plane of fixed link rack-plate 17
It contacts with each other, to achieve the effect that locking；When needing to dismantle sub-screen 1, rack bar 10, rack gear are similarly inwardly squeezed manually
Inwardly movement will drive the rotation of gear 12 to bar 10, and the rotation of gear 12 then will drive rack gear block 13 and be displaced outwardly, and rack gear block 13 can squeeze
Pressing spring 14 makes to generate gap between rack gear block 13 and fixed link 5, consequently facilitating it is separated from each other fixed block 7 with fixed link 5,
Then the tongue 3 of sub-screen 1 is separated with slot 4, to achieve the purpose that disassembly, passes through fixed block 7, tongue 3 in summary
With the cooperation of slot 4, solve in actual use that connector is complicated for operation, and connector is accounted for when connecting sub-screen 1
With the segment space of sub-screen 1, the using effect of mosaic screen is affected, while connector is not easy the middle part to sub-screen 1
Divide and be attached, 1 middle section of sub-screen is be easy to cause the problem of gap occur.
