Abstract: A hoverboard comprises a left supporting shaft, a right supporting shaft and wheels, wherein an outer end of the left supporting shaft and an outer end of the right supporting shaft are both connected to the wheels; an inner end of the left supporting shaft and an inner end of the right supporting shaft are relatively rotatably connected to each other; the inner end of the right supporting shaft is provided with a small outer-diameter portion which is adaptively inserted in the inner end of the left supporting shaft; a side wall of the inner end of the left supporting shaft is provided with an arc-shaped through hole; a lower end of a limiting bolt penetrates through the arc-shaped through hole to be fixedly connected to the small outer-diameter portion, and an upper end of the limiting bolt is at least higher than a lower edge of the arc-shaped through hole; and two inner side walls of the arc-shaped through hole in a lengthwise direction thereof define extreme positions of the relative rotation of the left

Abstract: A lockset and a door lock belong to the technical field of door locks. The lockset includes a drive shaft. Two ends of the drive shaft are respectively connected to handle assemblies. The handle assembly includes a handle and a lock seat. A linkage mechanism is provided between the handle of one of the handle assemblies and the drive shaft, and is configured to lock the handle and the drive shaft such that the handle and the drive shaft are circumferentially fixed. The other handle assembly is provided with a switch mechanism for driving the linkage mechanism to lock or unlock. When the switch mechanism drives the linkage mechanism to unlock, the handle is rotatable independently relative to the drive shaft. Therefore, the safety performance of the lockset is improved, and the service life thereof is extended.

Abstract: A retractable data cable is provided, including a housing, a conductive component, and a winding component. The winding component includes a first turntable and a second turntable, the first turntable is rotatably installed to a top surface of a first circuit board, the first turntable and the second turntable are clamped to respectively fix at a top surface and an undersurface of the conductive carrier, and a coil spring is installed on the second turntable. The data cable is wrapped on an outer side of the conductive carrier for fixation, and a plug component is fixedly installed at a leading-out terminal of the data cable. A positioning group is used to move the damaged area on the data cable due to frequent bending to the interior of the protective cover of the plug component for protection.

Abstract: A counterbalance hinge assembly includes a cam and compression device that counterbalances a weight of a door or a ramp. The compression device biases against a rotation of the door or ramp. The downward movement of the door or ramp drives cam followers in angled slots or cam surfaces of the cam. The angled slots or cam surfaces include varying angles of incline to correspond to varying torque forces of the door or ramp during the opening or closing movement of the door or ramp.

Abstract: A latching device may include an actuator configured to actuate between an actuated state and an unactuated state, a first rod including a threaded end, and a first rod coupler operatively coupled to the actuator and the first rod and configured to transfer force between the actuator and the first rod. The first rod coupler may include a rod receptacle configured to rotate about a first axis and to at least partially receive and engaged the first rod. The first rod coupler may also include a rod adjuster rotatably coupled to the rod receptacle and configured to rotate about a second axis to rotate the rod receptacle about the first axis. The rotation of the rod receptacle may change the position of the first rod relative to the actuator.

Abstract: A small volume door lock panel includes a panel mounting seat provided with a mounting cavity on one side, and a torsion head provided in the mounting cavity. A fixing member is provided in the mounting cavity. A mounting hole for clamping engagement with a mounting tool is formed in the fixing member. One end of the fixing member is provided with a connection part for connecting and fixing. A safety hole coaxial with and in communication with the mounting hole is formed on the panel mounting seat, a return spring for connecting is provided between the mounting cavity and the torsion head, ends of the return spring are both clamped into the mounting cavity, the torsion head is provided with control parts of a compression spring, and the mounting cavity is provided with a fixed blocking piece which limits the torsion head, the return spring, and the fixing member.

Abstract: Disclosed are a central control water path component, a bathing system and a control method of the central control water path component. The central control water path component includes: a water path component including a water inlet structure, a water outlet structure and a water path pipeline, where the water path pipeline includes a main water path whose two ends are connected with the water inlet structure and the water outlet structure correspondingly, and a branch water path whose two ends are connected with the main water path; a bath liquid filter bottle installed on the water path component and having a bath liquid filter cavity for receiving a water-soluble bath substance and connected to the branch water path; and a switch installed at an intersection of the main water path and the branch water path to selectively control the water outlet structure.

Abstract: A transparent lamp strip and a flame lamp of the transparent lamp strip are provided. A substrate is made of a transparent FPC material. A printed circuit is printed on the surface of the transparent FPC material. SMDLED lamp beads are fixedly arranged on the surface of the substrate and are electrically connected to a main control unit via the printed circuit. A light strip realizes the visual effect of simulating the flame and can realize 360° C. light emission, which makes the visual effect smoother.
