The specific embodiment

In conjunction with the accompanying drawings novel further describing done in this practicality:

As shown in Figure 1, the utility model is by lock body, and lock body shell and base plate 4 are formed, and lock body and lock body shell are installed on the base plate 4, and lock body comprises Cipher mechanism 1, locking mechanism 2 and tapered end 3.Cipher mechanism 1 comprises combination disk, trick lock 20, password shift fork 21 and password regulation and control bull stick 22.On the combination disk except that having a dark narrow password groove; also symmetry has two shallow wide rectangle combination disk counterweight grooves 18; protection sliding plate 19 is housed before the trick lock 20; trick lock 20 afterbodys are connected with lock head shifting fork 21; lock head shifting fork 21 is inserted in the groove of password regulation and control bull stick 22, and Cipher mechanism is that prior art is not done detailed description here.As shown in Figure 2, tapered end 3 is enclosed in the lock body shell 5, be installed in the top of base plate 4, locking mechanism 2 on wherein dead bolt 6 passes lock body shell 5 and is installed in base plate 4 is connected, locking mechanism 2 concealed installations are in lock body shell 7, locking mechanism 2 is by slide block 8, slideway 9, password driving lever 10 is formed, slideway 9 is I-shaped slideway, its upper and lower side is equipped with the groove slide rail, shape matches in one end shape of slide block 8 and the slideway, and in this slideway, slide, the other end of slide block 8 is fixedlyed connected with the dead bolt 6 that puts in lock body shell 7, password driving lever 10 is L shaped bar, fixedlys connected with dead bolt 6 in its upper end, and its lower end passes lock body shell 7 and is connected with the Cipher mechanism 1 that is installed in base plate 4 lower ends.Cipher mechanism 1 is contained in the lock body shell 11.As shown in Figure 3, at the keyhole face of tapered end, the password card and the password keyhole face thereof of Cipher mechanism one round sealed lid 12,13,14 is housed all, the center of closing cap 12,13,14 all has a circular hole 15,16,17.As shown in Figure 4, the centre of protection sliding plate 19 is provided with the key hole that matches with the key profile, as shown in Figure 5, the key hole of protection sliding plate be shaped as cross.During the utility model work; two keys are inserted respectively in the circular hole 17 of closing cap 14 in the circular hole 15 with closing cap 12; key in the circular hole 17 of closing cap 14 passes the cross bore in the middle of the protection sliding plate 19; enter in the tapered end 20; driving lock head shifting fork 21 by key turns rotates; driving password regulation and control bull stick 22 simultaneously rotates; and then combination disk is rotated; circular hole 16 by password card seal cover 13 is observed the password number; when to good password, the key in the circular hole 15 of rotation closing cap 12 drives dead bolt 6; coupled slide block 8 is slided in slideway 9, drive in the password groove that password driving lever 10 sticks into combination disk and can unblank.Otherwise sealed process and aforementioned.If password is not right, slide block can not move, and lock can not opened yet.

In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
