The fast lock mechanism that the present embodiment provides makes tightly being locked by locked mechanism of incomplete contact between by seamless spliced the fixing in the first installation position 7 and the second installation position 6, concrete, the axial slices of the first installation position 7 and the second installation position 6 is trapezoidal, when locked mechanism is locked, the plane contacted with the second installation position 6 on first installation position 7 is contact surface 701, the face contacted with the first installation position 7 on corresponding second installation position 6 is contact surface 601, the axis hole arranged on first installation position 7 is vertical with contact surface 701, and with the angled α of another plane of the first installation position 7；The axis hole arranged on second installation position 6 is vertical with contact surface 601, and with the angled α of another plane of the second installation position 6；
Accordingly, fixed pedestal 9 is fixing in a fixed angle α with the second installation position 6 to be connected, and the axial slices of fixed pedestal 9 is one trapezoidal, and the angle of the central shaft of trapezoidal hypotenuse and fixed pedestal 9 is α；
According to being actually needed of LED combination screen bending effect and angle, angle [alpha] being adjusted, in the present embodiment, α ranges preferably from 0 degree to 45 degree, and corresponding α is more big, and the degree of crook of LED combination screen is more low.
Fig. 6 is the LED unit screen structural representation being provided with locked mechanism of the embodiment of the present invention, LED combination screen includes several LED unit screen assembling combination and forms, and at least one side of LED unit screen is provided with lock solid structure provided by the invention and obtains the first connecting portion A and/or the second connecting portion B.LED unit screen side is provided with one or the first above connecting portion A, and opposite side is provided with and the second connecting portion B corresponding for connecting portion A with first.
LED unit screen includes front and back, and the locked mechanism of the present invention is located at the back side of LED screen, and in the present embodiment, the first connecting portion A and the second connecting portion B is respectively arranged on the upper side and lower side at the LED unit screen back side.
Fig. 7 is the assembled state figure of the LED combination screen being provided with locked mechanism of the present embodiment, figure includes two pieces of LED unit screens 24, the upside of first piece of LED unit screen 24 is provided with the first connecting portion A of locked mechanism, the downside of second piece of LED unit screen 25 is provided with the second connecting portion B, locked mechanism provided by the invention is clamped on the installation side of two module unit screens by the first installation position 7 and the second installation position 6 respectively, installs the groove that the prolongation limit that side can be vertically displayed plane can also be the LED unit screen back side.Two module unit screens are based on unit screen front face and keep two module unit screen clearance angle to carry out assembling combination for fixed angle β, and realize being locked of combination screen by the first connecting portion A and the second connecting portion B.In the present embodiment, the computing formula of β is:
β=2* (90 ° of-α)
Therefore, the angle of α is more little, and assembling " bending " degree of LED combination screen is more big, otherwise, the angle of α is more big, and assembling " bending " degree of LED combination screen is more little.
LED combination screen provided by the invention applies the operation principle of lock solid structure provided by the invention:
In locking process, grasp swivel head 11, LED unit screen is lifted, the motion pin spindle guide that motion bearing pin 12 is directed at the second installation position 6 enters taper hole 19 and inserts in sky, the only lockhole 21 that now slope driving at motion bearing pin 12 top stops on jam plate 4 starts to rotate around rotating hole 23, when motion bearing pin 12 end is completely into sorting hole 22, only jam plate 4 resilience under the reseting elasticity of torsion spring 2 drives, only lockhole 21 is made to be stuck on the only jam plate draw-in groove 14 of motion bearing pin 12, it is simultaneously emitted by resilience sound, completes pre-fixing of LED unit screen；
Further rotating swivel head 11, the screw thread between swivel head 11 and fixed pedestal 9 can be rotated 11 and move downward, and then makes motion bearing pin 12 move downward.Only jam plate draw-in groove 14 on motion bearing pin 12 and only gap shrinks between jam plate 4 are until being zero, two spacing ball headpin plugs 13 on motion bearing pin 12 slip in the hole 20, rotation location bottom swivel head 12 simultaneously, send the locking of hoodle sound prompt device, reach the purpose of the first connecting portion A and the second connecting portion B locking；
When needing to release, reverse rotation 11, swivel head 11 is driven to move upward by the screw thread between swivel head 11 and fixed pedestal 9, under the elastic force of spacing jump ring 10, brought into motion bearing pin 12 moves upward, only jam plate draw-in groove 14 and the gap stopped between jam plate 4 on motion bearing pin 12 increase, two spacing ball headpin plugs 13 on motion bearing pin 12 slip in two other hole 20, rotation location bottom swivel head 11 simultaneously, send hoodle sound prompt device and unclamp；
Because the only jam plate draw-in groove 14 on motion bearing pin 12 and the gap stopped between jam plate 4 increase, further rotating only jam plate hands 5 drives only jam plate 4 to rotate around only jam plate rotating shaft 17, only lockhole 21 is made to be gradually disengaged with the only locking trough 14 on motion bearing pin 12, when arriving sorting hole position, motion bearing pin 12 can completely disengage from only jam plate 4, and enter taper hole 19 from the motion pin spindle guide of the second installation position 6, now stop jam plate 4 resilience original position under the elastic force effect of torsion spring 2, reach the first connecting portion A and the second connecting portion B purpose released.
These are only present pre-ferred embodiments, be not used to the limitation present invention, all amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, all need to be included within protection scope of the present invention.
