Description
Technical field
The utility model relates to the sub-display screen technology field of LED electrical, specifically, relates to a kind of telescopic fast lock mechanism and LED combination screen.
Background technique
The sub-display screen of LED electrical, due to outstanding display effect and applicability, is widely applied in industries such as stage, commercial performance, advertisement, exhibitions.The sub-display screen of LED electrical is generally shielded by less unit and forms, and when showing area requirements and being larger, dozens or even hundreds of module unit may be needed to shield the use that is bolted together, and needs to consume a large amount of manpower and materials of display screen provider and goes to install and dismounting.Increasingly mature along with display screen leasing market, convenience and the Security of and dismounting assembled for display screen it is also proposed higher requirement.Traditional LED display generally adopts casing limit to lock, pulls the parts such as lock or connecting sheet to carry out the assembled of unit screen, and must use auxiliary mounting tool during fixed unit screen body, it exists various defect.Traditional LED display splicing structure mainly contains following several structural type:
1, casing limit lock
This casing limit lock is the most conventional LED display unit locking mode, in addition the instruments such as hexagon wrench must be used during the lower but locking of cost, not laborsaving during operation, and easily cause hook lock to be out of shape after long-term repeatedly use and then cause the precision reduction that locks between unit, and because cannot pre-fix, so be not suitable for lifting.
2, modified model casing limit lock
The Tool integration such as hexagon wrench on LED display unit, without the need to other carrying implement time assembled, are optimized assembled flow process, but do not have the performance boost of essence by modified model casing limit lock to a certain extent.
3, lock is pulled
Casing pulls lock to adopt the mode of thread locking, Long-Time Service amount of deformation is little, locking precision comparison is stablized, but complicated operation, need " after first being advanced by pull bar another block to shield body, half-twist, then the big nut that locked at middle part is tightened ",, when releasing, also there is the problem that not easily releases that locking tension causes in complex steps.
4, modified model pulls lock
Modified model pulls lock tradition to be pulled the big nut of lock locking to be improved to spanner style, and by modes such as adjustment tooth distances, simplify the stroke needed for locking, solve the problem not easily released, but still need " first advancing another block to shield and half-twist on pull bar; the big nut that locked at middle part is again tightened " this step, operate still very loaded down with trivial details.
5, pre-fix type and pull lock
This snap close utilizes a sliding jaw, pre-fixes, be applicable to the lifting mode of LED display, but need after pre-fixing to vacate hand when can realize lifting, and re-use the instrument carried with and carry out next step installation, process is loaded down with trivial details.
Several locked mechanism is several LED display unit locking mode of the prior art above, problems such as all there is complex operation, handling need be changed, single assembled difficulty, stability are not high, waste time and energy, efficiency is not high, location between unit screen body need rely on and install locating stud additional in addition, gap joint is difficult to control, display screen after assembling is not easy to dismounting, traditional splicing structure is not especially suitable for the sharpness screen higher to piece required precision, installs cause worry to large-area lease display screen.

Embodiment
Below in conjunction with accompanying drawing and mode of execution, the utility model is conducted further description:
As shown in Figure 1, a kind of telescopic fast lock mechanism, comprises the first joint 1 and the second joint 2, first joint 1 and is provided with the first installation position 10, installation position 10, first and is provided with flexible fastening sheet 20; Second joint 2 is provided with the second installation position 30 matched with the first installation position 10, second installation position 30 is fixedly connected with sleeve barrel fixed seat 40, sleeve barrel fixed seat 40 internal sleeve has sliding sleeve 50, sliding sleeve 50 slides along sleeve barrel fixed seat 40, sliding sleeve 50 is provided with sleeve pin 51, sleeve pin 51 is located in the chute 41 on sleeve barrel fixed seat 40, and slides along chute 41.
Be provided with elastic device between sliding sleeve 50 and sleeve barrel fixed seat 40, preferably, elastic device is spring 52.Sliding sleeve 50 is connected with rotating handles 70 by helix structure, and helix structure comprises is located at the internal thread 53 on sliding sleeve 50 and the outside thread 71 on rotating handles 70.
Rotating handles 70 is fixed with locking bearing pin 60, locking bearing pin 60 front end is fastened and connected with flexible fastening sheet 20 through sliding sleeve 50, elastic device, the second installation position, installation position 30, first 10 successively.Wherein, the rear end of locking bearing pin 60 is fixed on rotating handles 70 by fixing bolt 72, and the screens 61 of locking bearing pin 60 front end is fastened and connected with the draw-in groove 21 on flexible fastening sheet 20, and screens 61 is kidney-shaped head, and draw-in groove 21 is waist shaped hole.
As shown in Figure 2, a kind of LED combination screen being provided with fast lock mechanism, comprises several LED unit screen 3, and two the LED unit screens 3 be connected between two are called the first LED unit screen and the second LED unit screen relatively.First LED unit screen is provided with first joint 1 of or more, shields the second LED unit connected shield and be provided with second joint 2 corresponding with the first joint 1 with the first LED unit.
First joint 1 and the second joint 2 are located at the side of LED unit screen 3.Preferably, the first joint 1 is located at the right side of the first LED unit screen, and the second joint 2 is located at the left side of the second LED unit screen.
Working principle of the present utility model is:
In the process of locking: when two pieces of LED unit screens about 3 are close together, hold rotating handles 70, rotating handles 70 is promoted to the left side, rotating handles 70 drives sliding sleeve 50 and locking bearing pin 60 to left movement, sleeve pin 51 moves along the chute 41 on sliding sleeve 50, and spring 52 starts compression simultaneously; When sleeve pin 51 moves to high order end along the chute 41 on sliding sleeve 50, spring 52 is compressed to maximum flow, and the head of locking bearing pin 60, through flexible fastening sheet 20, exists gap between the kidney-shaped head of the bearing pin 60 that now locks and the waist shaped hole of flexible fastening sheet 20; Pull rotating handles 70 downwards, rotating handles 70 drives locking bearing pin 60 half-twist, the locking kidney-shaped head of bearing pin 60 and the cross-shaped state of waist shaped hole of flexible fastening sheet 20.In this course, due to the screw thread between rotating handles 70 and sliding sleeve 50, rotating handles 70 can be made to move right, haul locking bearing pin 60 simultaneously and move right, the locking kidney-shaped head of bearing pin 60 and the gap of flexible fastening sheet 20 are reduced to zero, complete locking action.
When needing to release, upwards pull rotating handles 70, due to the threading action between rotating handles 70 and sliding sleeve 50, rotating handles 70 can be made to left movement, push locking bearing pin 60 to left movement, the locking kidney-shaped head of bearing pin 60 and the gap of flexible fastening sheet 20 increase simultaneously; When rotating handles 70 drives locking bearing pin 60 half-twist, the kidney-shaped head of locking bearing pin 60 and the waist shaped hole of flexible fastening sheet 20 are state in the same way; Due to the effect of spring 52 elastic force, spring 52 promotes sliding sleeve 50, and interlock locking bearing pin 60, rotating handles 70 eject to the right, complete unlocking motion.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to the utility model claims.
