In addition, when the emergencies such as the inner breaking out of fire of boats and ships or water inlet, the personnel in the cargo hold can not accomplish rapid evacuation owing to can't open the cludy lid escape of locking in the cabin, exist serious potential safety hazard, threaten ship's staff's life safety.
The utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of little hatchcover that can two-sided unlatching, and the ship's staff is no matter in the cabin, can both open the little hatchcover of locking easily out of my cabin.
The technical solution of the utility model is:
A kind of little hatchcover that can two-sided unlatching, the surrounding edge that comprises hatchway cover, locks with hatchway cover, the surrounding edge embedding of opening a side at hatchway cover has pilot sleeve, tail end at pilot sleeve is provided with the locking member that docks with it, described locking member has the tapping circular hole that cooperates with pilot sleeve, is movably installed with one on the pilot sleeve for the locking bolt that is threaded with the tapping circular hole of locking member; Be provided with snap close for padlock at locking member to out of my cabin a side, be provided with hasp with described snap fit at hatchway cover, only need set up padlock at snap close, just can be with the cludy cover locking outside cargo hold.During use, if will open little hatchcover outside cargo hold, only need open padlock, separate released hasp, the cover plate that opens the cabin of then firmly pulling outward gets final product; If will in cargo hold, open little hatchcover, then first locking bolt is screwed out locking member, and take out from pilot sleeve, then firmly hatchway cover is pushed outward open getting final product.
Further, flow in the cabin from the slit of little hatchcover in order to prevent rainwater, the two ends of described pilot sleeve are provided with the rubber sheet gasket for sealing and waterproof.
Further, the inboard is provided with the groove that matches with surrounding edge around the described hatchway cover, is provided with in the groove for the rubber weather strip that improves cludy lid watertightness.
Further, described locking bolt comprises the screw mandrel that cooperates with the tapping circular hole spiral of locking member and the butterfly nut that is welded on the screw mandrel top.During with the cludy cover locking, need to screw in locking bolt in the locking member, make locking member and pilot sleeve affixed, if will in cargo hold, open little hatchcover, then want first locking bolt to be screwed out from locking member.
Further, described locking bolt is welded be used to the chainlet that prevents that it from losing, and the other end of chainlet is welded on the surrounding edge.
The beneficial effects of the utility model are: two-sided unlatching cludy Gai Nengcong peculiar to vessel of the present utility model uses padlock key to open out of my cabin, also can from the cabin inward turning bolt of unblanking, locking member be separated with surrounding edge, thereby open hatchway cover.The design can two-sided unlatching little hatchcover have simple for structure, easy to install, solid and reliable, use the advantages such as easy, both met the requirement of boats and ships property safety protection, staff on the boats and ships can be escaped rapidly when meeting accident, make things convenient for simultaneously the upper Lower Deck Cargo CompAtment of staff, minimizing is taken an unnecessary way, and has improved operating efficiency.
