The invention relates to a combined solid encapsulated pole and a working principle thereof. The combined solid encapsulated pole comprises an insulating cylinder with an upper cavity and a lower cavity, wherein one end of the insulating cylinder is connected to a seal cover. An outgoing line base is arranged at the left end inside the upper cavity, a pair of static conducting bases which are arranged at intervals and connected with each other are arranged in the middle, and a grounding base is arranged at the right end inside the upper cavity. The static conducting base at the left end is partially embedded in the left end inside the lower cavity. A screw rod for rotary positioning is arranged in the upper cavity, one end of the screw rod extends out of the seal cover, the screw rod is in threaded connection with a dynamic touch sleeve which is in contact match with the outgoing line base, the static conducting bases, and the grounding base and forms three conducting stations. A vacuum arc-extinguishing chamber is arranged in the lower cavity, the static contact of the vacuum arc-extinguishing chamber is connected to the static conducting base at the left end, the outer end of the dynamic contact is provided with soft connection and is fixedly connected with the left end of an insulating pull rod, the soft connection is connected with one end of a lower outgoing line rod fixedly sealed at the lower part of the insulating cylinder, and the right end of the insulating pull rod movably extends out of the seal cover. The combined solid encapsulated pole is small in size and relatively convenient and reliable to mount and use, and is suitable for being used as switch equipment.

The invention relates to release mechanisms, particularly to a universal type release mechanism. The universal type release mechanism solves the problem that existing release mechanisms are poor in safety and high in cost. According to the universal type release mechanism, a connecting plate is vertically arranged, two connecting rings are connected with the connecting plate in a fastened mode through a plurality of screw fasteners, and the central line of the two connecting rings coincides with the vertical central line of the connecting plate; the two connecting rings are symmetric to each other relative to the horizontal central line of the connecting plate; the V-groove of cutting explosives covers the entire horizontal central line of one side of the connecting plate, the initiating end of the cutting explosives is arranged outside the connecting plate and spaced from the neighboring side wall of the connecting plate at a distance of S; the cutting explosives are attached to the connecting plate through aluminum foil adhesive tapes; a detonator is adhered to the cutting explosives through insulating tapes and arranged between the initiating end of the cutting explosives and the neighboring side wall of the connecting plate, and the output end of the detonator is aligned to the upper surface of the cutting explosives. The universal type release mechanism can be applied to drop test of weaponry as wells as other mechanisms requiring a quick cutting function.

The invention provides an installation structure of the door and window auxiliary frame and the door and window outside frame. The door and window auxiliary frame consists of an upper auxiliary framematerial, a lower auxiliary frame material, a left auxiliary frame material, and a right auxiliary frame material, and the four auxiliary frame materials are correspondingly installed at a building opening; each auxiliary frame material is fixed on the inside wall of the building opening by fixed plates of the auxiliary frame; the fixed plates of auxiliary frame comprise an upper fixed plate and alower fixed plate; the door and window outside frame is arranged on the top end of each fixed plate of auxiliary frame by arranging fixed plates of outside frame, and the fixed plates of auxiliary frame are connected with the fixed plates of outside frame in a buckled mode; a plug-in head which is connected with the door and window outside frame in a plug-in mode is arranged on a horizontal plate, and the contact point on which the door and window outside frame is plugged on the outside of the plug-in head is sealed by sealant. A metal cover flashing used by the installation structure of thedoor and window auxiliary frame and the door and window outside frame is plugged into the integrative window more deeply, and the problem of rain leakage is thoroughly eradicated by gluing the sealanton the junctions of the materials; and a rainwater drainage structure is arranged on an external end of the metal cover flashing, and the rainwater directly flows down along a wall by a drainage lineof the rainwater drainage structure.

The invention relates to a rat-proof and anti-pressure prefabricated connection line and belongs to the fiber to the home solution technical field. The rat-proof and anti-pressure prefabricated connection line comprises a rat-proof and anti-pressure optical cable, a strengthening hanging wire and connectors which are connected with two ends of the rat-proof and anti-pressure optical cable; the rat-proof and anti-pressure optical cable includes an outer sheath, a stainless steel armoring tube and a tight-buffered optical fiber which are distributed sequentially from outside to inside; the strengthening hanging wire is connected with the rat-proof and anti-pressure optical cable through a strengthening rib; and the diameter of the strengthening hanging wire ranges from 1 mm to 1.2 mm. The rat-proof and anti-pressure prefabricated connection line has the advantages of convenient installation, high stability and high reliability and rat-proof and anti-pressure performance.

The invention provides an aluminum plastic reinforced type mullion structure which comprises a mullion profile strip. The two ends of the mullion profile strip are transversely connected to the middles of vertical frames arranged on the two sides of a building door window, the mullion profile strip vertically divides and reinforces the door window integrally, the upper portion and the lower portion of the mullion profile strip are each provided with an L-shaped glass embedding groove for fixedly installing glass, the outdoor side of the mullion profile strip is connected with a long-strip-shaped aluminum alloy profile plate in a clamping mode, and the outer side face of the aluminum alloy profile plate is connected with an outwards-convex long-strip-shaped mullion reinforcing part through fastening parts; the mullion profile strip is made of macromolecular thermal insulation profiles, the upper end and the lower end of the outer side face of the mullion profile strip are each provided with an inwards-concaved clamping groove, and the upper portion and the lower portion of the aluminum alloy profile plate are connected to the upper clamping groove and the lower clamping groove in a clamping mode through clamping edges and then fixedly installed on the outer side face of the mullion profile strip; the mullion reinforcing part is connected together with the aluminum alloy profile plate and the mullion profile strip in a fastening mode through the fastening parts formed by long bolts. The aluminum plastic reinforced type mullion structure has the advantages of being simple in structure, convenient to install and use, reliable in installation and use, good in operation convenience, capable of further improving the wind pressure resistance of a door window system and increasing the safety level and the wind pressure resisting level of the door window and the like.
