Assembling combination is carried out, and being locked for combination screen is realized by first connecting portion A and second connecting portion B.β in the present embodiment
Calculation formula is：
β=2* (90 ° of-α)
Therefore, α angle is smaller, and assembling " bending " degree of LED combination screen is bigger, conversely, α angle is bigger, LED groups
Assembling " bending " degree for closing screen is smaller.
The operation principle for the lock solid structure that LED combination screen that the present invention is provided is provided using the present invention is：
During locking, swivel head 11 is grasped, LED unit screen is lifted, motion bearing pin 12 is directed at the second peace
The motion pin spindle guide of dress position 6 enters taper hole 19 and inserted in sky, and the slope driving for now moving the top of bearing pin 12 stops stopping on jam plate 4
Lockhole 21 starts rotation around rotating hole 23, and when motion bearing pin 12 end is completely into sorting hole 22, only jam plate 4 is in torsion spring 2
Reseting elasticity drives lower resilience, make only lockhole 21 be stuck on the only jam plate neck 14 of motion bearing pin 12, be simultaneously emitted by resilience sound,
Complete pre-fixing for LED unit screen；
Further rotation swivel head 11, the screw thread between swivel head 11 and fixed pedestal 9 can drive swivel head 11 downward
Motion, and then move downward motion bearing pin 12.Move the only jam plate neck 14 on bearing pin 12 and only the gap between jam plate 4 is contracted
It is small until be zero, while the two spacing bulb plungers 13 moved on bearing pin 12 slip into the rotational positioning hole 20 of the bottom of swivel head 12
It is interior, the locking of hoodle sound prompt device is sent, the purpose of first connecting portion A and second connecting portion B lockings is reached；
When needing to release, first 11 are reversely rotated, swivel head 11 is driven by the screw thread between swivel head 11 and fixed pedestal 9
The only jam plate neck 14 on the motion upwards of motion pin axle 12, motion bearing pin 12 is driven under motion upwards, the elastic force of spacing jump ring 10
Gap increase between only jam plate 4, while the two spacing bulb plungers 13 moved on bearing pin 12 slip into the bottom of swivel head 11
Two other rotational positioning hole 20 in, send hoodle sound prompt device and unclamped；
Because stopping jam plate neck 14 and only the gap increase between jam plate 4 on motion bearing pin 12, only lock is further rotated
Wrench 5, which drives, to be stopped jam plate 4 and is rotated around only jam plate rotary shaft 17, make only lockhole 21 and the only locking trough 14 on motion bearing pin 12 by
Gradually separate, when reaching separation hole site, motion bearing pin 12 can completely disengage from only jam plate 4, and from the motion pin of the second installation position 6
Spindle guide enters in taper hole 19, and now only the resilience under the elastic force effect of torsion spring 2 of jam plate 4 is in situ, reach first connecting portion A and
The purpose that second connecting portion B releases.
These are only present pre-ferred embodiments, be not used to limitation the present invention, it is all the spirit and principles in the present invention it
Interior done modifications, equivalent substitutions and improvements etc., are required to be included within protection scope of the present invention.
