Assembling " bending " degree for closing screen is smaller.
LED combination screen provided by the invention is using the operation principle of lock solid structure provided by the invention：
During locking, rotating handles 11 is grasped, LED unit screen is lifted, motion bearing pin 12 is directed at second
The motion pin spindle guide of installation position 6 enters taper hole 19 and inserted in sky, and the slope driving for now moving the top of bearing pin 12 stops on jam plate 4
Only lockhole 21 starts to rotate 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 drive lower resilience, only lockhole 21 is stuck in only on jam plate neck 14 of motion bearing pin 12, be simultaneously emitted by resilience sound
Sound, complete pre-fixing for LED unit screen；
Further rotation rotating handles 11, the screw thread between rotating handles 11 and fixed pedestal 9 can drive rotating handles
11 move downward, and then move downward motion bearing pin 12.Move only jam plate neck 14 on bearing pin 12 and only between jam plate 4
Gap shrinks are until be zero, while move the rotation that two on bearing pin 12 spacing bulb plungers 13 slip into the bottom of rotating handles 12
In positioning hole 20, the locking of hoodle sound prompt device is sent, reaches the purpose of first connecting portion A and second connecting portion B lockings；
When needing to release, handle 11 is reversely rotated, rotation is driven by the screw thread between rotating handles 11 and fixed pedestal 9
Handle 11 moves upwards, drives motion pin axle 12 to move upwards under the elastic force of spacing jump ring 10, moves the only jam plate on bearing pin 12
Gap increase between neck 14 and only jam plate 4, while move two on bearing pin 12 spacing bulb plungers 13 and slip into rotation handle
In two other rotational positioning hole 20 of the bottom of hand 11, send hoodle sound prompt device and unclamped；
Because of the only jam plate neck 14 on motion bearing pin 12 and only the gap between jam plate 4 increases, and further rotation is only locked
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 reach separate hole site when, motion bearing pin 12 can completely disengage only jam plate 4, and from the motion pin of the second installation position 6
Spindle guide enters to be deviate from 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., it is required to be included within protection scope of the present invention.
