Long Circle holes

55,56,57 of drawing piece 51 then are placed on three projections 13,14,15 that are fixedly arranged on cassette holder 1 respectively.

This first key 6, (also claim construction key) its end face 61 of unblanking makes bolt locking bolt 3 can make the advance and retreat of segment section corresponding to drawing piece 51 outposts of the tax office of part; Please see Figure 3,4,5, when taking first key, 6 insertion keyholes 11 to clockwise rotate (Fig. 5), the end face 61 of unblanking of first key 6 can be stirred the moving tooth 31 of bolt locking bolt 3 and the drawing piece 51 of dead lock 5, make drawing piece 51 move left and right of dead lock 5 and bolt locking bolt 3 moves forward and backward, and snib 33 only can pass through to part position shown in Figure 5 (the part outpost of the tax office) in the shift position of fault-tolerant gap 54 and spacing teeth groove 53.

This second key 7, (also claiming real key), its end face 71 of unblanking made bolt locking bolt 3 can make the advance and retreat of full section corresponding to whole drawing piece 51 outposts of the tax office; Please see Fig. 3,4,6 again, when clockwise rotating (Fig. 6) with second key, 7 insertion keyholes 11, the end face 71 of unblanking of second key 7 can be stirred the moving tooth 31 of bolt locking bolt 3 and the drawing piece 5 of dead lock 5, make drawing piece 51 move left and right of dead lock 5 and bolt locking bolt 3 moves forward and backward, and snib 33 is in the fault-tolerant gap 54 of dead lock 5 and spacing teeth groove 53 section advance and retreat (can pass through whole outposts of the tax office) entirely.When snib 33 moves on to last spacing teeth groove 53, be all and unblank, as shown in Figure 4.

So-called " the drawing piece outpost of the tax office ", the end face 61 or 71 of unblanking that is meant first key 6 or second key 7 is stirred the moving tooth 31 of bolt locking bolt 3 and the drawing piece 51 of dead lock 5, make drawing piece 51 move left and right of dead lock 5 and moving forward and backward of bolt locking bolt 3, and form snib 33 in the fault-tolerant gap 54 of dead lock 5 and the advance and retreat position of spacing teeth groove 53, promptly form " outpost of the tax office " of switch section, as be designed to four sections switches, be exactly that switch all needs through four roads " outpost of the tax office ".

First key 6, the end face 61 of unblanking of second key 7,71 with the formation outpost of the tax office of drawing piece 51, be because first key 6 all has the different emboss pit (see figure 3) of the depth with the end face of second key 7, therefore when inserting keyhole 11 respectively, first key 6 and second key 7 (see Fig. 5, when 6) rotating, first key 6 or second key, 7 locking end faces 61,72 can stir each drawing piece 51 makes it form move left and right, and bolt locking bolt 3 is moved forward and backward, and order is fixed in the snib 33 of bolt locking bolt 3 about and is formed an outpost of the tax office of advancing and retreat 53 of the fault-tolerant gap 54 of drawing piece 51 and spacing teeth groove and (see Fig. 5,6).

Here it is takes first key 6 (construction key) use can only make snib 33 by the fault-tolerant gap 54 of dead lock 5 and the part outpost of the tax office of spacing teeth groove 53, after construction, must take second key 7 (real key) could pass through full section (all) outposts of the tax office, and prevent the contingent drawback of unworthy person's pirate first key.

By this, when being formed, door lock can have at least two kinds of different rights controls, as shown in Figure 5, first key 6 unblank end face 61 only pair of latches locking bolt 3 have the unlatching authority of segment section, snib 33 promptly is subjected to spacing can not advancing afterwards, as shown in Figure 6,7 of second keys have the complete right end face 71 of unblanking, but pair of latches locking bolt 3 full sections are opened.So, when decorateing or be for sale, the house trustship can hand over attached first key 6 practicality in, do the use of part authority for the caretaker, and can prevent that so other people pirate from invading protecting the safety of life, property, and avoid changing the trouble of lock and meaningless waste afterwards.

In addition, can have various embodiments when it is made, promptly set fault-tolerant gap 54 can be single or multiple configuration on one group of dead lock 5, shown in Fig. 7-A can with should in the logical fault-tolerant gap of widening 54 be disposed on the single drawing piece 51.Or be disposed on the drawing piece 51 of (1 pair 6) or (2 pairs 5) or (3 pairs 4) upper and lower symmetry, its difference is in the number of fault-tolerant tooth position and first key 6 and second key 7 unblank end face 61, and whether balanced configuration of 71 both sides, if only on monolithic, offer single fault-tolerant gap 54 certainly, its lockset is used more fragile because of having only single retaining tooth event, if but fault-tolerant gap 54 is established too much then can be caused serious forgiveness to strengthen on one group of dead lock 5, cause that any key all can be opened and the essence justice meaning that loses control of authority.

Therefore, preferred embodiment can be established the fault-tolerant gap of widening 54 at the first two section teeth groove 53 on the aforementioned symmetry group drawing piece 51 shown in Fig. 7-B, and foot makes and produces suitable serious forgiveness, and has the dual firm retaining tooth of paired configuration.
