Patent number: 10492317Abstract: A latching structure includes a first plate, a second plate and a sliding plate disposed on a surface of the first plate and movable in a first direction. The first plate includes first arches each having an alignment hole in the first direction. The second plate includes second arches each having a latching hole in the first direction. The sliding plate includes pins corresponding to the latching holes. When the alignment hole accommodates the second arch and the sliding plate is located at a latching position, the pin is located in a corresponding latching hole to block separation of the first plate from the second plate in a second direction. When the sliding plate is located at a retracted position, the pin separates from the corresponding latching hole to allow separation of the first plate from the second plate in the second direction.Type: GrantFiled: April 15, 2019Date of Patent: November 26, 2019Assignee: SERCOMM CORPORATIONInventors: Li-Li Ho, Cheng-Chung Chang, Yi-Fei Yu

Patent number: 7320555Abstract: A cardan shaft structure with tightness adjustable functions has a through-hole passing through spheres located at both ends of the cardan shaft body, and a taper socket respectively installed into the opening end of each sphere. A bolt is inserted into both spheres and the body, fixed and locked together in conjunction with a nut. The cardan shaft structure works together with two clamping components wrapping around the spheres. When the sphere is being pushed against (or freed from) the inner wall of the clamping component by tightening (or loosing) the bolt so as to make the sphere either expand (or recover), the angle displacement of the clamping component becomes adjustable accordingly.Type: GrantFiled: October 14, 2005Date of Patent: January 22, 2008Assignee: Sercomm CorporationInventors: Cheng-Chung Chang, Yi-Fei Yu
