Patent number: 8480044Abstract: An omni-direction rotatable dual-cup suction device includes two suction cups, which are respectively combined with and in communication with two evacuation structures, so that the two evacuation structures can evacuate air from the suction cups to induce vacuum suction forces. The two suction cups are respectively provided with a mounting seat and an attaching seat for securely coupling the two evacuation structures. The mounting seat includes a pillar fixed thereto. A collar receives a ball end of a bar therein and is attached to the pillar. The ball-ended bar is coupled to a threaded rod, which extends through an internally-threaded locking knob and received into the attaching seat to be secured by a nut. With such an arrangement, one of the suction cups can be attached to a planar fixture surface, while the other suction cup can be used to hold an article and is orientation adjustable in any direction.Type: GrantFiled: September 20, 2010Date of Patent: July 9, 2013Assignee: Lih Yann Industrial Co., Ltd.Inventor: Po Lin Liao

Patent number: 8418522Abstract: A hand/pneumatics dual operation vacuum pulling device includes an elongate shank and a slidable backward ram fit to the shank. The shank has an end to which a suction cup is attached. The shank has an upper end to which a handgrip having a pressure relief seat is mounted. A ramp stop section is formed below the pressure relief seat. The handgrip can selectively and switchably couple with a hand-operating pump piston to form a hand-operating vacuum pulling device, or couple with a pneumatic operation seat to form a pneumatically-operating vacuum pulling device. For hand operation or pneumatics operation, the vacuum pulling device is allowed to easily switch between the two modes according to the availability of power supply and the site of use, thereby achieving an excellent device for one device having two ways of use.Type: GrantFiled: December 27, 2011Date of Patent: April 16, 2013Assignee: Lih Yann Industrial Co., Ltd.Inventor: Po Lin Liao

Patent number: 7673914Abstract: An automatic alert device is provided for a suction cup, including a pump and a suction cup positionable on an object to be handled. The pump is operable to drive air out of the suction cup thereby inducing suction force on the object to be handled. When the suction cup gradually loses the suction force, a plunger of the pump gets moved out of the pump. When the outward movement of the plunger reaches a preset extent, the alert device that includes a warning light and an audio alert is activated to cause the warning light and the audio alert to give off warnings of light and sound respectively. Thus, an operator can be immediately notified of the situation of losing suction force for taking remedial operation to get the suction force back to the desired level.Type: GrantFiled: December 27, 2007Date of Patent: March 9, 2010Assignee: Lih Yann Industrial Co., Ltd.Inventor: Po Lin Liao

Patent number: 7621375Abstract: Disclosed is a pneumatic grease applicator includes a receptacle in which a retainer that forms a tubular axle selectively fit into a bearing to which grease is to be applied and a presser that defines a bore fit over the axle are movably received. The presser forms a top cavity in which a nozzle for coupling an external grease source is fixed. Grease is pneumatically supplied through the nozzle into the tubular axle and discharge through radially-extending holes defined in the axle to cover the bearing fit on the axle. An air vent is formed in the presser for pressure balance. Sealing members are provided between side wall of the receptacle and both the retainer and the presser to prevent leakage of grease.Type: GrantFiled: July 21, 2006Date of Patent: November 24, 2009Assignee: Lih Yann Industrial Co., Ltd.Inventor: Lin Po Liao
