Dislocation in the front-back direction reduce or be not present, rotation lock is next can to tense multiple screen bodies simultaneously, and each side edge is kept to spell
It is consistent to connect post gap, it is preferable to spell screen effect.Since existing locking mechanism is to be separately provided, locking mechanism individually locks locking group
The sticking department 7 of part keeps the locking dynamics of each locking mechanism different, and for successively locking can not be expendable locked, each locking
The independent stress of sticking department 7 of component causes strength suffered by the sticking department 7 of each locked component different, makes side up and down
To screen after splicing suffered dynamics it is inconsistent, to generate assembled gap, gap is inconsistent, and assembled screen is more, tire out
The assembled error of meter is bigger, bad so as to cause whole display effect, and individual locking mechanism needs manually to examine one by one after locking
Look into whether lock locks, extra step process wastes time.
Embodiment two
Referring to Fig. 7, the utility model implements second is that arc lock slots 4 and lock room propose on the basis of example 1
Another technical solution, with embodiment one the difference is that: 4 width of arc lock slots is constant, the end of arc lock slots 4
Not-go-end is equipped with limit film 16.Specifically:
A limit film 16 can be set in the opening of the clearing end of the arc lock slots 4, preferably has gap 17
Limit film 16, lock room, i.e. arc lock slots 4 is collectively formed in the limit film 16 and the clearing end of arc lock slots 4
It is finally the position that the rotation of rotating seat 3 terminates with the matched position of locking column 5, the gap 17 of limit film 16 will be contradicted in locking column
On 5 peripheral wall, a part of the end of locking column 5 will be received in the region between the bottom surface of arc lock slots 4 and limit film 16,
So that limited post 5 cannot be further continued for mobile and cannot be detached from rotation lock, to form limit.
In conclusion rotation lock provided by the utility model, rotation latch mechanism and display device, pacify without using auxiliary
Holding tool, user, which need to only rotate rotating seat, can be completed the lock locking/unlocking of rotation lock, operate extremely simple；Rotation lock can be with
Object to be locked is kept completely separate, one can be operated, and is conducive to save human and material resources；Positioning component is arranged can be to rotating seat and solid
The relative positional relationship of reservation is locked, and prevents rotating seat from unexpected rotation occur, conducive to the stabilization for improving rotation lock work
Property；The quantity of positioning component is stability that are multiple, working conducive to guarantee rotation lock；Be arranged the clamping block being connect with rotating seat and
Arc lock slots are arranged on clamping block, reduce the difficulty of processing of rotating seat, produce convenient for manufacturer；When there is arc lock slots to go out
After now damaging, user, which replaces corresponding clamping block, can be used continuously rotation lock, conducive to economizing on resources, reduce user's use at
This.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
