CN2142481Y - Improved cipher lock - Google Patents

Abstract

The utility model relates to an improved cipher lock. The utility model is mainly characterized in that an L-shaped pushing block which can be linked with a control button is arranged between a fixed base and an upper cover. When type wheels are poked to correct digits, a gap at the side edge of a rotating wheel which is arranged at the lower part of the type wheels is aligned with the salient sheet of the L-shaped pushing block. When the control button is poked with lateral push, the salient sheet of the L-shaped pushing block is inlaid into the gap of the rotating wheel. At the moment, the bolt of the L-shaped pushing block is caused to be disengaged with the clasp of a fastening body from fastening; then, the cipher lock can be opened. When the cipher lock is opened, fingers no longer laterally push and press the point of the control button; then, the L-shaped pushing block is caused to return to original position, due to the elastic recovery of a spring which is arranged between a cross bore in the L-shaped pushing block and the guide post of the fixed base.

Description

Improved cipher lock

The utility model relates to a kind of structure improved combination lock, and main improvement is partly to be with one-body molded at L type pushing block, has convenience simple in structure and when making.

A kind of combination lock of adjustable conversion number is finished in the design people Ceng Zaiyi design in 9 years, it promptly as shown in Figure 5, it is characterized in that a brake block 4 is located at the position of loam cake 3 top square openings 133, brake block 4 is provided with two circular grooves 141, and be provided with through hole 143 at the groove face center, simultaneously be provided with small sircle hole 142 at central through-hole 143 periphery rings, and the bottom of brake block 4 is established to be connected with in an end of slipping block 2 with two protruding bolts 144 and is the interlock state, two runners 5 are located in two circular grooves 141, the upper and lower surface of runner 5 respectively is provided with little protruding grain 151, and the number of the protruding grain 151 in top is more than the bottom, and each protruding grain (can't see in this figure) of bottom can be sticked in the suitable small sircle hole 142 of circular groove 141 groove faces, a buckle piece 153 is extended in the bottom of runner 5, penetrate in the through hole 143 of brake block 4, the footpath edge of this buckle piece 153 is provided with a groove 154 and several safety vents 155, flange 134 same horizontal planes with loam cake 3, the top of runner 5 is rotary column 152, fit is with letter disk 6 and flexure strip 161 in regular turn, be incorporated into topmost with a clipping sheet 162 again, can make aforementioned each member of sealing, integral body is closed by a drag housing 164 covers more then, the sub-fraction of two letter disks 6 of only surplusing is exposed, and aforesaid letter disk 6 bottom surfaces also be provided with respect to circular groove 141 groove faces etc. number small sircle hole (not shown in the figures) in this, protruding grain 151 for runner 5 tops is chimeric, and the frictional force that makes 6 of runner 5 and letter disks is than the frictional force greater than circular groove 141 groove faces.

When using, be to rotate by the part that letter disk 6 exposes in drag housing 164 outsides, and by letter disk 6 chimeric by the protruding grain on its bottom surface small sircle hole and the runner 5 151, driving runner 5 rotates in the circular groove 141 of brake block 4, when turning to the setting number, promptly allow the flange 134 of groove 154 and loam cake 3 square openings 133 sides on the runner 5 lower snap pieces 153 align, and can stir brake block 4, because brake block 4 is to be connected with in the blocking hole 122 of slipping block 2 with the protruding bolt 144 in below, thereby can drive slipping block 2 compression springs 123 and in holder 1, do displacement by brake block 4, allow dead bolt 121 be shifted, and reach the purpose of unblanking, again when the user desires number that change setting unblanks, be about to brake block 4 and remain on the position of unblanking, and the powerful letter disk 6 that rotates, because this moment, the groove 154 of runner 5 can't be rotated by flange 134 blockings, thereby can be when letter disk 6 rotates, flexure strip 161 is compressed, and the protruding material 151 of the small sircle hole of letter disk 6 bottom surfaces and rotating disk 5 tops is broken away from, reach the unblank purpose of number of change setting.

But can find after above-mentioned combination lock structure analyzed: holder 1 has four fixing feet 111, and be provided with a flexure strip 112 in the one end, its upper side is established with slipping block 2, one end of slipping block 2 is established dead bolt 121, between aforementioned two flexure strips 112, its other end utilizes two springs 123 to be equipped in the inner edge of holder 1, the elastic force of slipping block 2 one to flexure strip 112 1 ends is provided, centre end in slipping block 2 is made as crowned in addition, and offer with two blocking holes 122, cause overall structure comparatively complicated, when making assembling, rather bother and inconvenience.

Main purpose of the present utility model is to overcome the above-mentioned inconvenience of existing in prior technology and a kind of structure improved combination lock is provided, mainly be to be arranged in holder and the loam cake with the L type pushing block of control knob interlock with one, when stirring character wheel in correct number, even being located at the runner side breach of character wheel below and the lug of L type pushing block aligns, when control knob is moved in horizontal pushing, the lug of L type pushing block is embedded in the breach of runner, make this moment the dead bolt of L type pushing block and the clasp of buckling body break away from blocking, then the number lockset can be opened, after opening, point no longer horizontal pushing pressure-controlled button place, L type pushing block is replied because of the spring of being located between its interior cross-drilled hole and holder guide pillar, L type pushing block is kept in the center, have convenience simple in structure and that make, be rated as a progress, practical novel designs.
