Abstract:
A lens focusing assembly (100) and a projector. The lens focusing assembly (100) comprises: a lens barrel (10), provided with a barrel body (11) and a limiting structure (12), the barrel body (11) defining an accommodating space (13), and the barrel body (11) being provided thereon with a through groove (14); a focusing ring (20), sleeved on the barrel body (11) and rotatable around the barrel body (11), the focusing ring (20) being provided thereon with a groove (21), the groove (21) being provided along a helical line; the limiting structure (12), stopping the focusing ring (20) from rotating along the axis of the barrel body (11); a moving assembly (30), comprising a supporting member (31) and a fitting member (32), the supporting member (31) being used for fixing a lens (40) and arranged within the accommodating space (13), and the fitting member (32) being extended from the supporting member (31), ran through the through groove (14), and fitted into the groove (21). When the focusing ring (20) rotates around the barrel body (11), the groove (21) fits the fitting member (32) and drives the fitting member (32) to move back and forth in the through groove (14), the fitting member (32) concurrently drives the supporting member (31) to move along the axis of the barrel body (11) within the accommodating space (13). The lens focusing assembly (100) implements adjustments to the position of the lens (40) with the joint actions of the lens barrel (10), the focusing ring (20), and the moving assembly (30), and thus is structurally simple, is easy to operate, and has a small footprint.
