In conjunction with the accompanying drawings, the implementation procedure of concise and to the point narration the utility model Strong chain lock: the utility model Strong chain lock construction is very simple, form by board-like inner core 1, overcoat 3, key 6, tapered end 7 and chain, chain is seamless ring fastening type, be that the latch closure joint is handled by welding or additive method, to increase its intensity, so do not shown in the accompanying drawing.Key 6 is general key, so repeat no more.Bottom is narrated other several members respectively:

Inner core 1: inner core 1 is a plank frame, and for the sake of assurance, suitable steel plate generally is advisable with rectangle can to select thickness for use.Correspondence is removed a part respectively in the both sides of an end of its length, make its top be a semicircle, the both sides, bottom of semicircle have circular arc in respectively, bore the circular hole that diameter is suitable at the home position of semicircle, this circular hole is an inner core chain connecting hole 2, do not have the other end on semicircle top to bore one again than the big circular hole of inner core chain connecting hole 2 diameters at inner core 1, this circular hole is tapered end perforation 9, the diameter of tapered end perforation 9 should be suitably greater than the cylindrical external diameter of tapered end 7.

Tapered end 7: tapered end 7 is identical with common tapered end basically, for cylindrical, pin 12 is positioned at the front end of tapered end 7, because tapered end 7 is a cylinder, tapered end perforation 9 on the member inner core 1 matching used with it and the tapered end jack 8 on the overcoat 3 are circular hole, for ease of the lock unlatching, so the outside that has key hole one end end of tapered end 7 be processed with one with overcoat 3 on groove 4 corresponding identical tapered end boss 5 (Fig. 4, Fig. 5), tapered end 7 can not be rotated freely on the tapered end jack 8 of overcoat 3.

Overcoat 3: overcoat 3 is a hexagonal prism, in fact cube structure also can, this mainly considers from angle attractive in appearance.On the suitable steel side's body of size, process a rectangle groove, the degree of depth is suitable, can not bore the bloom body, its length, width are bigger slightly than the length and width of the thickness of inner core 1, can be can make inner core 1 from wherein inserting smoothly and extraction is advisable, and this rectangle groove is an inner core jack 13.Process a circular hole inwards in the center in the outside of square bar body again, circular hole pass rectangular inner core jack 13 with its in vertical state, but do not see through the square bar body, this does not see through the circular hole of square bar body, is tapered end jack 8.Pass in the proper site processing of inner core jack 13 the interior round groove of a triangle or rectangle at tapered end jack 8, one side of its close inner core jack 13 is parastate with one side of inner core jack 13 length, and the interior round groove and the part between the inner core jack 13 of this triangle or rectangle are pin baffle plates 11.In the side processing of the end, insert division of tapered end jack 8 one with tapered end 7 on the groove 4 that matches of tapered end boss 5, be inserted in the tapered end jack 8 of overcoat 3 with convenient tapered end 7 after when pin 12 after the interior round groove of pin baffle plate 11 front ends stretches out, tapered end boss 5 just in time enters in the groove 4 of tapered end jack 8 ends on the overcoat 3.When inner core 1 bore a hole from its tapered end 9 ends be inserted into the inner core jack 13 of overcoat 3 and its end with after the bottom of inner core jack 13 contacts, tapered end jack 8 on the overcoat 3 is concentric with tapered end perforation 9 on the inner core 1, and the diameter of these two circular holes is all greater than the external diameter of tapered end 7.In fact, for easy to use, the tapered end perforation 9 tapered end jacks 8 that are a bit larger tham on the overcoat 3 on the inner core 1, again process that inner core jack 13 and end have groove 4 and in inner having four right angles of the one side that has inner core jack 13 of the square bar body of the tapered end jack 8 of annulus groove remove, make it to form an octahedron.At last the semicircle steel plate that has overcoat chain connecting hole 10 is welded on the correspondence position of inner core jack 13 blind ends of overcoat 3.In fact, overcoat chain connecting hole 10 is need not steel plate welding with holes good, also can directly process on the square bar body, but processing capacity is too big, generally is welded as suitable with steel plate with holes.The steel plate that has overcoat chain connecting hole 10 should be identical with the thickness of inner core 1, and the diameter of inner core chain connecting hole 2 should be identical with the diameter of overcoat chain connecting hole 10.
