Abstract

The invention relates to the field of rear projection screen mounting, in particular to a locking mechanism for a rear projection screen frame. The locking mechanism comprises a supporting structure and a screen-hanging structure, the supporting structure is fixed on a rear projection screen case by a screen-sliding structure on the rear projection screen case, and the screen-hanging structure can be fixed on the screen frame; the supporting structure comprises a supporting part, a locking structure, hangers and a through hole, the supporting part can be fixed on the screen-sliding structure, the locking structure is mounted on the supporting part, the hangers are arranged on the supporting part, and the through hole is arranged on the supporting part and located over the hangers; the screen-hanging structure is provided with hanging holes which can be fastened with the hangers, and the supporting structure can be fixedly connected with the screen-hanging structure through the hangers and the hanging holes; one end of the locking structure is heavier than the other end of the locking structure, and when the heavy end of the locking structure is pushed, the light end of the locking structure can run through or get out of the through hole. The structure of the screen frame is simple, locking and unlocking steps are simple, the difficulty of operation is decreased, and operators can be liberated from complex unlocking and locking operations.

Description

technical field [0001] The invention relates to the field of rear projection screen installation, and more particularly, to a locking mechanism for a rear projection screen frame. Background technique [0002] At present, the screen of the front-maintenance large-screen rear projection unit is generally attached to the mechanism of the cabinet, and the screen is fixed on the mechanism through a series of locking and unlocking systems. But existing locking and unlocking systems also have some disadvantages: [0003] One is that the locking mechanism is too complicated, which makes it very difficult to disassemble and assemble the screen; [0004] The second is that the existing large-screen rear projection unit screens are generally multi-layer spliced ​​together, so that for the screen system above the second floor, the operator needs to cooperate with more than two people, and use scaffolding or other tools to reach the height of the second floor before dismantling.
