| 20110088494 | DEVICE FOR GENERATING OSCILLATING MOTION | 04-21-2011 |
| 20120222506 | Reciprocating Pump Drive Apparatus for Operating a Downhole Pump Via a Rod String - A reciprocating pump jack employs a crank arrangement to drive a polish rod carrier up and down, and employs guide slots in side walls of a frame structure at both ends of the carrier in order to maintain tight control over the orientation of the polish rod. | 09-06-2012 |
| 20120279330 | Transmission mechanism of eyebrow tattoo machine - The present invention refers to a transmission mechanism of an eyebrow tattoo machine, which includes an eccentric rotation shaft connected to a driving axle of a motor and having a bottom end configured to rotate eccentrically with respect to the driving axle, an upper bearing coupled with the bottom end of the eccentric rotation shaft, a position-limiting cover longitudinally provided with a position-limiting groove, and a swinging rod element mounted to the upper bearing and provided with a swinging rod and a position-limiting rod on two sides respectively. Since the position-limiting rod is only allowed to swing up and down in the position-limiting groove when the eccentric rotation shaft drives the upper bearing and the swinging rod element, the end of the swinging rod away from the upper bearing can swing up and down and then drive a tattoo needle to move vertically up and down through a lateral bearing. | 11-08-2012 |
| 20130199315 | LEVER CONTROL MECHANISM OF A DRAIN VALVE OF A TOILET TANK - A lever control mechanism of a drain valve of a toilet tank has a lever assembly assembled in the wall of the toilet tank and a lever linked to the revolving shaft of the lever assembly. The lever assembly is connected to a deviator, which is disposed with a drive arm; the drive arm is connected to the revolving shaft. The deviator is disposed with a joint portion and at least a leading hole to limit the lever revolving vertically. One end of the lever is run through the leading hole to rotationally connect to the joint portion; the drive arm is revolved by the driving of the revolving shaft to drive the lever revolved in the fan shaped vertical surface limited formed by the joint portion and the leading hole. | 08-08-2013 |
| 20130199316 | MECHANICAL DEVICE WITH VARIABLE-LENGTH LEVER ARM - A mechanism which comprises at least one fulcrum element connected to at least one force transmission rod by a connecting member is provided. The mechanism may convert a reciprocating rectilinear movement into a rotational movement of the at least one fulcrum element. The rotation of the at least one fulcrum element may cause the at least one force transmission rod to rotate. The connecting member comprises a part, known as a lever arm that may be situated between the at least one fulcrum element and the at least one force transmission rod and has a length that varies during the relative movement of the at least one fulcrum element with respect to the at least one transmission rod. | 08-08-2013 |
| 20140123785 | OSCILLATION TOOL - An amplitude of an oscillating shaft to which a tip tool is attached is changed. An oscillation tool | 05-08-2014 |
| 20140174216 | ROTARY PLATFORM DEVICE - A rotary platform device is for supporting and rotating an assembly. The rotary platform device includes a rotary platform and a casing. The rotary platform extends up from the casing. The casing accommodates a driving device, a coupling member, and a linkage bar. The driving device provides linear motion, which is translated by the linkage bar to rotary motion applied to the rotary platform. | 06-26-2014 |
| 20140174217 | APPARATUS FOR FRONT/TOP LAY VERTICAL ADJUSTMENT AND SHEET-FED ROTARY PRINTING PRESS HAVING THE APPARATUS - An apparatus for the vertical adjustment of combined front/top lays in a sheet processing machine includes a front/top lay carrier shaft carrying the front/top lays jointly in such a way that it can be pivoted with respect to a front/top lay drive shaft, or thrust joints disposed in carriers or coupling links for the front/top lays in such a way that they effect a lengthening of the carriers or coupling links in order to adjust the front/top lays. A sheet-fed rotary printing press having the apparatus, is also provided. | 06-26-2014 |
| 20150040694 | RECIPROCATING ROCKING DEVICE - A reciprocating rocking device for the rocking of a chair or cradle, the chair or cradle having rockers and a seat member, the reciprocating rocking device comprising a base secured to the rockers, the base comprising a first bracket, a second bracket secured to the seat member of the chair or cradle, a tension member connected to the second bracket, an eccentric, the eccentric constantly engaged with the second bracket and, a motor secured to the first bracket, the motor having a drive shaft operatively arranged to drive the eccentric, wherein the motor is coaxially arranged with the eccentric. | 02-12-2015 |
| 20150068333 | TRANSMISSION STRUCTURE OF A FILLING MACHINE - A transmission structure, which is connected to a motor of a filling machine so as to drive a transmission operation of the filling machine, includes a transmitting wheel, a swing set, a clamper, a lift set, a supporting plate and a transmitting set. Under this arrangement, the swing set, the lift set and the transmitting set cooperate with each other via only the transmitting wheel, rather than cooperate with each other via a plurality of members corresponding to different sets as the prior art. Therefore, the structure of the present invention is simpler than that of the prior art; a weight or a volume of the present invention is littler than that of the prior art. In addition, the present invention is easier to maintain than the prior art, because the structure of the present invention is simpler than that of the prior art. | 03-12-2015 |
