This utility model relates to the technical field of optical device coating equipment, and particularly to a coating fixture for an open-aperture lens. The open-aperture lens has a coating surface at one end along the axial direction and a positioning part at the other end. The open-aperture lens also has a through hole along the axial direction. The coating fixture includes a fixture body and a fixing member. A positioning groove is provided at the bottom of the fixture body, and a through hole communicating with the positioning groove is provided at the top of the fixture body. The positioning groove is used to position the positioning part. The fixing member passes through the through hole and the through hole in sequence. One end of the fixing member has a limiting part that can be engaged in the through hole, so that the positioning groove positions the positioning part. The coating fixture for the open-aperture lens provided by this utility model can reliably fix and accurately position the lens without obstructing the coating surface.

The utility model discloses a wave trap, including shell and be located in the inner shell of shell, fixedly connected with inner core and inductance coil on the inner shell, be equipped with the aperture unit for fixing inner core and inductance coil on the inner shell, form the cambered surface unit between aperture unit and the outer wall of inner shell, and aperture unit extends to the inside of inner shell and forms the convex unit, and aperture unit intercommunication cambered surface unit and convex unit. The utility model discloses reasonable structure design, and the aperture of inner shell side surface and bottom surface all adopt non - material punching process, and the aperture around convex circle forms convex unit, increases the interface of the component of interface, and the cambered surface unit is formed to the outside of aperture, forms the tin dissolving groove, makes tin not to flow to other position, guarantees that tin and the interface of component are covered well, thereby guarantees that the welding is good, and it is not easy to appear the phenomenon of false welding.

The invention discloses a positioning and trepanning jig for a lens frame of VR glasses and a positioning and trepanning method of the positioning and trepanning jig. The two reference cylinders are vertically arranged on the workbench, and the reference cylinders are movably arranged in the lens openings of the lens frame in a penetrating mode; the lower ends of the poking pieces are installed on the outer wall of the reference cylinder in a turnover mode, a plurality of penetrating holes are formed in the reference cylinder, the inner sides of the poking pieces are connected with supporting and ejecting rods, the supporting and ejecting rods movably penetrate through the penetrating holes, and elastic pieces are installed between the supporting and ejecting rods and the penetrating holes; a supporting plate is erected on the workbench, the supporting plate is arranged above the two reference cylinders, the supporting plate is provided with the extrusion part in a lifting mode, and the outer diameter of the extrusion part is gradually increased from bottom to top; the punching mechanism is installed on the bearing plate in a lifting mode, and the punching mechanism is aligned to the hole opening position of the lens frame. The lens frame punching device solves the problem that when a common positioning device is used for positioning a lens frame for punching, the punching position is not accurate.

The invention discloses a lens fastening structure and a simulation calculation method of a fastening ring corner. The fastening structure comprises a lens seat, a lens, a fastening ring, a sliding block and a pressing ring. The lens is in threaded connection with the lens mount; an external thread is arranged on the outer surface of an opening position for mounting the lens on the lens seat and is matched with the internal thread on the fastening ring; meanwhile, circular holes are uniformly formed in the lens seat along the circumference, and the sliding blocks are mounted in the circular holes in the lens seat and slide along the radial direction of the lens seat; and internal threads are arranged on the inner surface of the opening position for mounting the lens on the lens seat and are matched with the external threads on the pressing ring. And the rotation angle of the fastening ring is calculated through a simulation method. Compared with the prior art, by screwing the fastening ring, the sliding blocks evenly arranged on the lens seat in the radial direction are pressed at the same time in the radial direction, the lens is evenly stressed, and according to a lens fastening structure simulation model, the maximum displacement of the fastening ring in the axial direction of the lens can be solved in a step-by-step displacement accumulation loading mode when a part does not generate plastic deformation.

The utility model belongs to the technical field of glass production, and particularly relates to a window structure and a storage bin, the window structure is arranged on the top wall of the storage bin, and the top wall is provided with an opening communicated with an inner cavity of the storage bin. The window structure comprises a first cover plate covering the open hole and a second cover plate arranged on the side, away from the inner cavity, of the first cover plate, the first cover plate is provided with a plurality of observation openings communicating with the open hole, and the second cover plate is rotationally or slidably connected with the first cover plate so that the observation openings can be opened. Or the first cover plate is laminated with the first cover plate so as to cover the observation opening. According to the utility model, the problem of how to improve the safety of observing the storage condition of the storage bin by an operator can be solved.
