  • the safety buckle resetting member 361 is a return spring in the present embodiment, which is sleeved on the safety buckle shaft 362 and elastically acts between the safety buckle 360 and the right seat body 30, so that the left assembly 2 and the right assembly 3 When in the locked state, the safety buckle 360 can hold the wrench 31 so that the left assembly 2 and the right assembly 3 are reliably locked.
  • the specific structure of the safety buckle 360 is as shown in FIG. 19, and the lower end is provided with a safety buckle shaft mounting hole 3601, and the upper end has a hook 3602.
  • the hook 3602 on the safety buckle 360 holds the wrench 31.
  • the middle portion of the wrench 31 is provided with a hook hole 317 corresponding to the position of the hook 3602 on the safety buckle 360.
  • the hook 3602 has a guiding slope 3603, so that when the right assembly 3 and the left assembly 2 enter the locking state, the hook 3602 hooks the wrench 31 to enter the insurance state.
  • the safety buckle 360 has a pressing surface 3604. When the insured state needs to be released, the pressing surface 3604 can be pressed by a finger, and the safety buckle 360 rotates around the safety buckle rotating shaft 362 against the action of the safety buckle resetting member 361, so that the hook 3602 is disengaged from the wrench 31, so that the safety can be easily released. status.
  • the display quick splicing device further includes an open state.
  • the open state retaining member 39 is also disposed between the moving member and the stationary member of the right assembly 3, which enables the right assembly 3 to remain in the maximum open state when the hook 32 is not hooked to the lock cylinder 21.
  • the open state retaining member 39 is specifically a tension spring that is stretched between the positioning post 37 and the right seat body 30 to pull the positioning post 37 into the right seat body 30, thereby ensuring The positioning post 37 does not protrude from the X-right positioning surface 300 in the non-locking state. Since the quick splicing device of the display screen of the invention can realize the mutual splicing between the display screens quickly and conveniently without any tools, the flexible splicing device can flexibly adapt to various use occasions; and the main parts thereof include the rotation angle seat 21 and the right side.
  • the seat body 30, the hook 32, the wrench 31, the safety buckle 360, and the like can be manufactured by a die-casting process and a machining process, and the manufacturing precision can be up to 0.02 mm.
  • the structure of the present invention can be designed to prevent high-density pixel display applications by innovating and subtly transferring the structural design of the contact members to prevent damage between adjacent display unit units due to squeezing. And through the precision machining and processing technology control of the assembled contact parts, the ideal assembly effect can be achieved. The total error after assembly can be controlled within 0.1mm, and the stitching accuracy can be improved by an order of magnitude, which can not only achieve fast Locked and precise locking.

Abstract

Cette invention concerne un appareil d'assemblage rapide d'écrans de visualisation, ledit appareil comprenant un ensemble gauche (2) et un ensemble droit (3) aptes à être bloqués l'un par rapport à l'autre. Ledit ensemble gauche (2) comprend un support de fixation rotatif (22), un support d'inclinaison rotatif (20) et un mécanisme de blocage de rotation. Ledit support d'inclinaison rotatif (20) est apte à bloquer l'ensemble droit (3). De plus, ledit support d'inclinaison rotatif (20) est relié rotatif au support de fixation rotatif (22). Quand le mécanisme de blocage de rotation est débloqué, le support d'inclinaison rotatif (20) et le support de fixation rotatif (22) peuvent pivoter l'un par rapport à l'autre. Quand le mécanisme de blocage de rotation est bloqué, le support d'inclinaison rotatif (20) et le support de fixation rotatif (22) sont reliés l'un à l'autre de manière fixe. L'appareil d'assemblage rapide d'écrans de visualisation selon l'invention assure l'assemblage rapide d'écrans de visualisation de forme arquée et il assure de plus un assemblage et un blocage précis. Les pièces principales dudit appareil d'assemblage peuvent être fabriquées par coulée sous pression associée à un procédé d'usinage pour une précision de fabrication à 0,02 mm près, et la marge d'erreur des écrans de visualisation après assemblage peut être contrôlée à 0,1 mm près. De ce fait, la précision d'assemblage est considérablement accrue.
