Patent number: 11959535Abstract: A continuously variable transmission with both equal-difference output and equal-ratio output includes an input mechanism, a hydraulic transmission mechanism, a planetary-gear-set convergence mechanism, an equal-difference output mechanism, an equal-ratio output mechanism, a clutch assembly, and a brake. The clutch assembly connects an output end of the input mechanism to an input end of the hydraulic transmission mechanism and the planetary-gear-set convergence mechanism and connects an output end of the hydraulic transmission mechanism to the planetary-gear-set convergence mechanism. The clutch assembly connects the planetary-gear-set convergence mechanism to the equal-difference output mechanism and the equal-ratio output mechanism. The clutch assembly connects the equal-ratio output mechanism to the equal-difference output mechanism.Type: GrantFiled: January 10, 2022Date of Patent: April 16, 2024Assignee: JIANGSU UNIVERSITYInventors: Zhen Zhu, Lingxin Zeng, Yingfeng Cai, Long Chen, Yanpeng Yang, Dongqing Wang, Yulin Deng, Xiaodong Sun, Xiang Tian, Yong Wang, Falin Zeng, Chaofeng Pan

Publication number: 20230358078Abstract: The disclosure provides a retractable childproof lock. The lock includes a lock body and a lock tongue arranged in a mode of retractable movements, so as to achieve objectives of locking or unlocking through retractable movements of the lock tongue. When being locked, the lock tongue is extended relative to the lock body, so that a locking end approaches relative to a first surface of the lock body in a first direction, but moves away from relative to a second surface of the lock body in a second direction, in such a way, an outward-opening moving part of a household product is locked due to blocking of the front end of the extending lock tongue.Type: ApplicationFiled: July 13, 2023Publication date: November 9, 2023Inventors: Zhen Zhang, Yingfeng Chen

Patent number: 11761240Abstract: The present utility model discloses a safety lock device including a first lock body and a second lock body. The first lock body is provided with a movable member, a first action member and a second action member. The second action member and the first action member are operated sequentially to enable the movable member to act to unlock. The first action member or the second action member is operated individually that cannot achieve the unlocking. The unlocking of the safety lock device is completed only by fitting the two moving members with each other, thereby solving the problems of the easy unlocking by children and the potential safety hazards.Type: GrantFiled: September 30, 2020Date of Patent: September 19, 2023Assignee: Ningbo Eudemon Child Protective Equipment Co., Ltd.Inventors: Zhen Zhang, YingFeng Chen

Patent number: 11746577Abstract: The invention belongs to the technical field of daily necessities, and particularly relates to an unlocking and locking method of a cabinet lock and a cabinet safety lock. During unlocking, a lock rod is displaced relative to a locking assembly to release the locking of the lock rod, and a first lock rod is rotated to an unlocked position. During locking, the first lock rod is rotated to a locked position and the locking assembly is engaged with the lock rod to lock the second lock rod. The method and the cabinet safety lock have a novel operating mode, have a firm structure, are convenient to use, and can effectively avoid unauthorized operation by children.Type: GrantFiled: February 5, 2021Date of Patent: September 5, 2023Assignee: Ningbo Eudemon Child Protective Equipment Co., Ltd.Inventors: Yingfeng Chen, Zhen Zhang

Publication number: 20230068935Abstract: The present disclosure provides a rotary door stop. The rotary door stop includes a door stop rotation base and a door stop body. The door stop body rotates about the door stop rotation base to define a locked state or an unlocked state. By engagement between a first limiting portion and a second limiting portion, the rotary door stop is retained in the locked state for ease of door closing; and when the rotary door stop approaches a door frame, retention of the unlocked state may also be released while the door is closed.Type: ApplicationFiled: November 8, 2022Publication date: March 2, 2023Applicant: Ningbo Eudemon Child Protective Equipment Co., Ltd.Inventors: Yingfeng Chen, Zhen Zhang

Publication number: 20220202184Abstract: The present disclosure relates to the technical field of household products, and in particular, relates to an anti-tilt assembly of a cabinet. The anti-tilt assembly includes a first anti-tilt member and a second anti-tilt member that are disposed at an angle of 90 degrees relative to each other. A first connecting surface configured to be connected to a fixing surface is defined outside the first anti-tilt member. A second connecting surface configured to be connected to the cabinet is defined under the second anti-tilt member. With such configuration, a top portion or an upper portion of the cabinet is fixed to the fixing surface, thereby achieving an anti-tilt effect.Type: ApplicationFiled: January 25, 2021Publication date: June 30, 2022Inventors: Zhen ZHANG, Yingfeng CHEN

Patent number: 11359614Abstract: The present invention discloses a power head of a vertical reciprocating pump with multi-spherical connection, and a water injection pump using the same, which includes a hydraulic end, a centralizing sleeve, an adjustable ball seat, a circular pull-back plate, pull rods of the power head, and a hydraulic end, an integrated base and the alike. By using the structure with multiple movable spherical surfaces, the error of the oblique disk during its motion along the elliptic trajectory can be eliminated. The power end can be linked with hydraulic ends and can be applied to boosting water injection processes for feeding liquid at low pressure or feeding liquid at high pressure in oil fields and various high-pressure liquid delivery fields. The fast on-site installation of the water injection pump of the present invention can be realized by the integrated base, so as to save the investment and improve the safety factor.Type: GrantFiled: July 1, 2019Date of Patent: June 14, 2022Assignee: NINGBO HELI MECHANICAL PUMP CO., LTD.Inventors: Minghai Chen, Yingfeng Chen, Heping Liu
