6results about How to "Simplify the “alignment” process" patented technology

This application relates to a duct mechanism and an air supply device. The duct mechanism includes: a duct assembly comprising a duct shell and a bushing, the outer wall of which has a first positioning portion radially; and a support base having a shaft hole channel, the two opposite ends of which along their axial direction are an inner end near the duct shell and an outer end away from the duct shell, respectively, and a stop portion surrounding the outer end is formed on the support base; wherein the bushing passes through the shaft hole channel from the outer end and is detachably connected to the duct shell, and the bushing is also rotatably connected to the shaft hole channel, and the stop portion is used to stop and limit the first positioning portion along the axial direction of the bushing. The duct mechanism of this application simplifies the positioning and alignment process of the duct assembly and support base during assembly, quickly and accurately completing the rotatable connection assembly of the entire duct assembly and support base, improving the connection efficiency and accuracy of the duct assembly and support base, reducing the production difficulty of the duct mechanism, and improving the production quality and efficiency of the air supply device.

The application provides a medical wireless energy transmission system and an implantable medical device. The system comprises a first device end including a control unit, a phase reconstruction network and at least one pair of antennas arranged side by side; the control unit is connected to the phase reconstruction network, and the phase reconstruction network is connected to the at least one pair of antennas; in a positioning mode, the control unit controls the phase reconstruction network to input excitation signals with opposite phases into the pair of antennas to form an energy null region in space; during relative movement between the first device end and a second device end, when the antenna of the second device end is in the energy null region, a low signal is detected, and the control unit identifies whether the second device end is aligned with the first device end according to the low signal; in an energy transmission mode, the control unit controls the phase reconstruction network to input excitation signals with the same phase into the pair of antennas to form a signal enhancement region. The pair of antennas arranged side by side can realize alignment of the wireless energy transmission device and efficient wireless energy transmission at the same time.

This utility model discloses a lightweight PVDF pipe, comprising a pipe body, a first reinforcing part slidably mounted on the outside of the pipe body, and a second reinforcing part movably mounted on the outside of the first reinforcing part. Limiting parts are also provided at both ends of the pipe body. The pipe body includes a first tube body with uniformly distributed grooves on its outer wall. The first reinforcing part includes a second tube body slidably mounted on the outer wall of the first tube body. Uniformly distributed inserts are provided on the inner wall of the second tube body, and these inserts are inserted into the grooves and slidably mounted. The first reinforcing part slides with the grooves on the outer wall of the first tube body via wedge-shaped inserts on the inner wall of the second tube body. The guiding effect of the wedge-shaped inserts simplifies the alignment process, eliminating the need to install components one by one; assembly can be completed simply by pushing along the axial direction. The second reinforcing part is installed by screwing on internal and external threads. Compared to the traditional method of assembling semi-ring reinforcing plates one by one, this significantly shortens the assembly time.

The utility model relates to a kind of inside and outside door handle mounting structure and house door, including house door, outdoor handle and indoor handle, including guide block, welding nut and counter-pulling screw;The welding nut is welded on outdoor handle;The guide block includes installation part and guide part, the guide block is clamped on welding nut by installation part, the inner hole of guide part is gradually increased horn-like structure from outdoor to indoor direction;The counter-pulling screw is sequentially passed indoor handle, house door and the guide part of guide block and is screwed on the welding nut.The utility model can avoid the problem of difficult hole alignment caused by hole position deviation when artificial alignment.

This invention discloses an adaptive balancing lifting device for aircraft door assembly and disassembly, belonging to the field of lifting device technology. It includes a lifting frame, lifting components, and a clamping assembly. The clamping assembly is equipped with a flexible component containing magnetofluid and a corresponding excitation component, which can adapt to the curved surface of the door and actively harden to provide reliable clamping. The lifting device also integrates a multi-degree-of-freedom angle adjustment component and a vision-feedback-based active balancing system. Before handling, the clamping angle can be adjusted to align the door using the longitudinal and lateral adjustment components. During handling, a vision camera detects the door's attitude in real time, and the control system drives independent lifting components on both sides for dynamic leveling. Micro-vibrations are absorbed by adjusting the magnetofluid state, achieving adaptive flexible gripping, precise attitude adjustment, and stable anti-sway handling of irregular doors, significantly improving the safety, accuracy, and efficiency of assembly and disassembly operations.

The utility model relates to a supporting leg poking and mounting device and crane mounting equipment, and the supporting leg poking and mounting device comprises a moving assembly, a first sliding rail and an auxiliary pushing assembly, the moving assembly is movably arranged on the first sliding rail and supports one end of a to-be-mounted supporting leg; the auxiliary pushing assembly is arranged on the moving assembly in a telescopic mode and abuts against the rear side face of the supporting leg to be installed. According to the supporting leg poking and mounting device, the supporting legs are accurately, safely and efficiently pushed into the supporting leg cavities, and the manual mounting burden is effectively reduced.
