Abstract: A preload biased structure of a linear rail includes a rail and a sliding block disposed on the rail. The sliding block includes a sliding base, a supporting element, two connecting pieces and two locking pieces. The sliding element is provided with a connecting space. The front and rear end of the sliding base each is provided with abutting pieces. The abutting piece extends to form a biased block toward the connecting space. The biased block extends to form a biased slope. In assembling, the biased slope guides the supporting element to be inserted in the connecting space. The biased block provides a preloading force, whereby the supporting element can be fixed in the sliding base in advance. The locking pieces lock the two connecting pieces on both ends of the sliding base, so that the supporting element and the two connecting pieces can be assembled on the sliding base.

Abstract: An engaging device of a linear sliding rail includes a sliding rail and a sliding block. The sliding block comprises a sliding base body, a supporting body and two connecting bodies. The front and rear ends of the sliding base body have a positioning plate respectively. The two locking pieces each comprises hooks. The hook locks the two connecting bodies at the front and rear ends of the sliding base body. The hook abuts against one end of the abutting piece. The other end of the abutting piece abuts against front and rear end faces of the supporting body respectively. Via this arrangement, when the locking piece locks the two connecting bodies at both ends of the sliding base body, it also generating a pre-pressure to press the supporting body, thereby assembling the supporting body and the two connecting bodies on the sliding base body tightly and firmly.

Abstract: A water level detecting device for an ice-making machine includes a transparent tube, a float set in said transparent tube, an infrared ray emitter and an infrared-ray receiver respectively installed in a line at opposite sides of said transparent tube connected to a water tube connected to a water tank. When the float falls down together with the water level in the transparent tube going down with that of the water tank, and positions between the infrared-ray emitter and the receiver, a pump supplying water to an ice making unit is to be stopped by the interruption of the function of the infrared-ray emitter and the receiver. Thus the pump is automatically stopped in case of the water in the tank becoming insufficient, impossible to work idle.
