3results about How to "Guaranteed assembly reliability" patented technology

This utility model relates to the field of military equipment technology, specifically to a parachute compartment assembly and clamping device, comprising a positioning plate, a lead screw fixedly mounted on the top of the positioning plate via a bearing seat, an internally threaded block threaded to the outer surface of the lead screw, a sliding column fixedly connected to the outer end face of the internally threaded block, and a parachute compartment disposed outside the sliding column for housing a deceleration parachute; a clamping block, comprising an expansion component for controlling the clamping block to expand outward to adapt to parachute compartments of various sizes, a filling component that automatically fills gaps in the expansion component when it expands outward, and a positioning component for locking the adjusted diameter of the expansion component. By setting up the clamping block, this utility model not only allows for the expansion or contraction of the clamping block without changing tooling when assembling parachute compartments of different sizes, flexibly adapting to parachute compartments of different diameters, but also automatically fills gaps generated during the expansion process, preventing uneven stress on the deceleration parachute.

The utility model relates to high pressure switch field especially relates to movable contact structure and arc extinguishing chamber and high pressure switch. Movable contact structure includes movable contact seat, and movable contact seat includes a assembly cylinder section, and the front end of assembly cylinder section is connected with auxiliary spout through inner thread section, and the inner and outer circumferential surface between auxiliary spout and assembly cylinder section is equipped with still the concave-convex cooperation structure of forcibly radial occlusion together when auxiliary spout is screwed to the spin into tail section on assembly cylinder section, and still install movable arc contact assembly in assembly cylinder section, and movable arc contact assembly extends into auxiliary spout and with the inner circumferential surface of the part of auxiliary spout and assembly cylinder section assembled connection is inlayed, to carry out the location in the direction of its inward, keep the occlusion state of concave-convex cooperation structure. This movable contact structure can keep the occlusion of concave-convex cooperation structure through movable arc contact assembly after assembly is completed, thereby guaranteeing the reliable connection between auxiliary spout and assembly cylinder section.

The utility model relates to a kind of filter systems for lens with lotus petal type lens hood, including connection seat and one above filter that are sequentially magnetically attracted and stacked in the front end of connection seat;The connection seat is circular ring, and its inner side surface is equipped with one above limiting portion, each The limiting portion is clamped on the recess between the two petal-shaped edges of lotus petal type lens hood, and the connection seat assembled to the front end of lens is limited in circumferential direction and front-back direction;The rear end of the connection seat has the hoop of integrated connection, and the hoop is sleeved on lens, and the connection seat is locked on lens.By setting limiting portion, the connection seat assembled to the front end of lens is limited in circumferential direction and front-back direction, ensure that the position of filter system is consistent in front-back direction when assembling to lens each time, ensure the assembly stability and reliability of filter system and lens.
