Patent number: 11988321Abstract: A height-adjustable standing post belongs to the technical field of height-adjustable devices. The height-adjustable standing post includes: a driving tube, an outer tube, a first fastener and a second fastener. The driving tube is supported on the ground. The outer tube is sleeved outside the driving tube, and the outer tube is allowed to rise and fall. The first fastener is provided between the driving tube and the outer tube, and the first fastener is fixed relative to a position of the driving tube. The second fastener is provided between the driving tube and the outer tube, and the second fastener is fixed relative to a position of the outer tube. The second fastener is provided with an auxiliary locking member, and the auxiliary locking member is used to manually lock the outer tube. The height-adjustable standing post has a wide height adjustment range, and is stable.Type: GrantFiled: January 28, 2022Date of Patent: May 21, 2024Assignee: ZHEJIANG INTIAN HEALTH TECHNOLOGY CO., LTD.Inventors: Peng Wang, BiSheng Zheng

Publication number: 20230029553Abstract: A fastening screw and a height-adjustable table using the same are provided. A threadless transition portion is provided between a threaded section and a head portion of the fastening screw to increase the contact area between the screw and a workpiece, and to cooperate with a shaft portion to fasten the workpiece. The transition portion is provided with a tapered wall surface, and the transition portion expands from the threaded section to the head portion of the screw. The screw offers a tension expanding outward in a circumferential direction of a mounting portion. An area of a joint between the transition portion and the head portion does not exceed a circumferential area of threads. In a direction of a central axis of the screw, the projection of the transition portion overlaps that of the shaft portion, which prevents the transition portion from falling off the workpiece or damaging the workpiece.Type: ApplicationFiled: January 28, 2022Publication date: February 2, 2023Applicant: ZHEJIANG INTIAN HEALTH TECHNOLOGY CO.,LTD.Inventors: Peng WANG, BiSheng ZHENG

Patent number: 11564482Abstract: A screw rod self-locking device includes a one-way bearing and a mounting seat, and an inner hole of the one-way bearing is sleeved at an end of a screw rod. A mounting hole for receiving the one-way bearing is disposed on the mounting seat, and the one-way bearing is rotatably fitted into the mounting hole along a circumferential direction. An adjusting mechanism for adjusting a circumferential locking force of the mounting hole for the one-way bearing is disposed on the mounting seat so as to adjust a size of a friction force between an outer wall of the one-way bearing and an inner wall of the mounting hole. A height-adjustable leg and a height-adjustable desk applying the same are further provided. In this way, a size of a self-locking friction force to be overcome during backward rotation of a screw rod can be self-defined, thereby guaranteeing consistency of product performances.Type: GrantFiled: August 17, 2021Date of Patent: January 31, 2023Assignee: NINGBO INTECH SMART TECHNOLOGY CO., LTDInventor: Bisheng Zheng

Patent number: 11564483Abstract: A height-adjustable desk includes a desk board and a base. Two first lifting arms and one second lifting arm are disposed between the desk board and the base. The two first lifting arms are disposed at both sides of the desk board respectively. The second lifting arm is located between the two first lifting arms and spatially intersected with the two first lifting arms to be distributed in an X shape. The upper ends of the two first lifting arms are rotatably connected to a first end of the desk board, and the lower ends of the two first lifting arms are slidably connected to a first end of the base. The upper end of the second lifting arm is slidably connected to a second end of the desk board, and and the lower end of the second lifting arm is hinged to a second end of the base.Type: GrantFiled: August 17, 2021Date of Patent: January 31, 2023Assignee: NINGBO INTECH SMART TECHNOLOGY CO., LTDInventor: Bisheng Zheng
