Description
Technical field
It is to be related to a kind of LED combination screen fast lock specifically the present invention relates to LED electronic display technical fields
Mechanism.
Background technology
LED electronic displays are obtained due to outstanding display effect and applicability in industries such as stage, commercial performance, advertisement, exhibitions
Extensive use is arrived.LED electronic displays are typically made up of less unit screen, when showing that area requirements are larger, Ke Nengxu
Want dozens or even hundreds of module unit screen to be bolted together to use, it is necessary to which consuming the substantial amounts of manpower and materials of display screen provider goes installation
And dismounting.It is increasingly mature with display screen leasing market, it is assembled and convenience and security of dismounting are also carried for display screen
Higher requirement is gone out.Traditional LED display typically carries out unit screen using parts such as casing side lock, pulling lock or connection sheets
Assembly, must use auxiliary mounting tool during fixed cell screen body, it is single assembled difficult, take and not laborsaving, unit screen body
Between positioning need to be by installing alignment pin additional in addition, gap joint is difficult to control to, and the display screen after assembling is not easy to dismounting, tradition
Splicing structure be particularly unsuitable for the sharpness screen higher to piece required precision.
Traditional LED display splicing structure mainly has following several structure types：
1st, casing side is locked
This casing side lock is most conventional LED display unit locking mode, and cost is relatively low but must be in addition when locking
It is not laborsaving during operation using instruments such as die nuts, and it is long-term be used for multiple times after easily cause hook lock deform so that cause unit it
Between locking precision reduction, and because that can not pre-fix, be not suitable for lifting.
2nd, modified casing side is locked
Modified casing side lock need not be taken in addition by the Tool integrations such as die nut to LED display unit when assembled
Band instrument, optimizes assembled flow, but the performance boost without essence to a certain extent.
3rd, lock is pulled
Casing pulls lock by the way of thread locking, and long-term use deflection is small, and locking precision is more stable, but operation
Complexity, needs " first promote after another piece of screen body pull bar, be rotated by 90 °, then middle part locking big nut is tightened ", complex steps, pine
Also there are problems that being difficult to release caused by locking tension during button.
4th, modified pulls lock
Modified pulls lock to pull the big nut for locking locking to be improved to spanner style tradition, and by adjust tooth away from etc.
Mode, simplifies the stroke needed for locking, solves the problem of being difficult to release, but still needs to " pull bar first be promoted another piece of screen simultaneously
It is rotated by 90 °, then middle part locking big nut is tightened " the step, operate or troublesome.
5th, pre-fix type and pull lock
This lock utilizes a sliding jaw, it is possible to achieve pre-fixed during lifting, it is adaptable to the lifting side of LED display
Formula, but need to vacate hand after pre-fixing, reuse the instrument carried with and carry out next step installation, process is cumbersome.
Several locked mechanisms are several LED display units locking modes of the prior art above, there is operation numerous
It is trivial, need hand-off operation, single assembled difficult, stability is not high, waste time and energy, it is inefficient the problems such as, between unit screen body
Positioning need to be by alignment pin be installed additional in addition, and gap joint is difficult to control to, and the display screen after assembling is not easy to dismounting, traditional assembly
Structure is particularly unsuitable for the sharpness screen higher to piece required precision, and the lease display screen to large area, which is installed, to be made
Into worry.

The present invention operation principle be：
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 in taper hole 19 and patchhole, and the slope driving for now moving the top of bearing pin 12 stops on jam plate 4
Only lockhole 21, make only jam plate 4 start rotation around rotating hole 23, when being inserted into certain depth, motion bearing pin 12 end is entered completely
When entering sorting hole 22, the only resilience in the case where the reseting elasticity of torsion spring 2 drives of jam plate 4, make only lockhole 21 be stuck in motion bearing pin 12 only
On jam plate neck 14, resilience sound is simultaneously emitted by, pre-fixing for LED unit screen is completed.
Now rotate rotating handles 11 by hand again, the screw thread between rotating handles 11 and fixed pedestal 9 can drive rotation handle
Hand 11 is moved downward, and then compressing motion bearing pin 12 is moved downward.Move only jam plate neck 14 and only jam plate 4 on bearing pin 12 it
Between gap shrinks until be zero, while the two spacing bulb plungers 13 moved on bearing pin 12 slip into the bottom of rotating handles 12
In rotational positioning hole 20, send hoodle sound prompt device and locked.Reach and lock first connecting portion 25 and second connecting portion 26
Tight purpose.
During releasing, hand holds rotating handles 11, reversely rotates the handle 11, rotating handles 11 and fixed pedestal 9
Between screw thread, the motion upwards of rotating handles 11 can be driven, due to the presence of limited location jump ring 10, and then motion bearing pin 12 is driven
Only jam plate neck 14 and the only gap increase between jam plate 4 on motion upwards, motion bearing pin 12, while moving on bearing pin 12
Two spacing bulb plungers 13 are slipped into two other rotational positioning hole 20 of the rotation of the bottom of rotating handles 11, send hoodle sound
Suggestion device has been released.
Only lock spanner 5 is stirred with thumb again, due to the only jam plate neck 14 on motion bearing pin 12 and only between jam plate 4
Gap increases, thumb can drive only jam plate 4 rotated around only jam plate rotary shaft 17, make only lockhole 21 with motion bearing pin 12
Only jam plate neck 14 is progressively disengaged, and when reaching separation hole site, motion bearing pin 12 can completely disengage from only jam plate 4, and from second
The motion pin spindle guide of installation portion 26 enters in taper hole 19, and now only the resilience under the effect of the elastic force of torsion spring 2 of jam plate 4 is in situ, reaches
The purpose that first connecting portion 25 and second connecting portion 26 are released.
It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
