Description
Technical field
The utility model relates to a kind of mechanical lock, is specifically related to a kind of mechanical code lock.
Background technology
The existing mechanical lock is made up of core, lock body, opens the lock with the key.As home-use lock, more convenient.But this lock because the people is many, need be joined many keys if be used for office's door lock, nor convenient, if there is a people to lose key, for the sake of security, just needs to change door lock, bitting again.Electronic lock unblanks conveniently also not need bitting, but trouble is installed, complex structure, and easy crack, poor stability, and expense is high.
Summary of the invention
The purpose of the utility model is the shortcoming that will overcome above-mentioned technology, provides a kind of simple in structure, easy to manufacture, uses the mechanical code lock easy to operate, that safety is good.
The mechanical code lock of the utility model comprises lock body and is arranged on the locking bolt on the lock body, it is characterized in that: the fixed head, unlatching axle, mess code assembly and the camshaft that are provided with the band central axis in the described lock body; Described fixed head is provided with pinning spring assembly and numeric keypad; Central axis is provided with opens plate and flange assembly, on the unlatching plate, is provided with and corresponding pinning spring assembly of fixed head and semi-circle gear, and unlatching plate and flange assembly are emitted by the central axis spiral shell and tighten up; Described unlatching axle is provided with opens gear, driven gear and unlatching handle; Camshaft is provided with cam and end tooth wheel; Locking bolt is provided with the locking bolt thrust pin assembly that is connected with cam.
In order better to realize above-mentioned purpose, described locking bolt is provided with the return spring assembly
Described flange assembly is provided with the password setting button.
The mechanical code lock of the utility model, simple in structure, easy to manufacture; Easy to install, do not need key, only need on numeric keypad, to be provided with and the input password; Just unlock operation can be accomplished, when password is revealed or forgotten, only password need be reset; Need not change lock, economy and safety are good.

The specific embodiment
The mechanical code lock of the utility model comprises lock body 20 and is arranged on the locking bolt 6 on the lock body 20.Be provided with fixed head 1, unlatching axle 26, mess code assembly 19 and the camshaft 5 of band central axis 8 in the lock body 20.Fixed head 1 is provided with pinning spring assembly 11 and numeric keypad 15.Central axis 8 is provided with opens plate 2 and flange assembly 18; Opening plate 2 is provided with and fixed head 1 corresponding pinning spring assembly 11 and semi-circle gear 22; Flange assembly 18 is provided with password setting button 25; Opening plate 2 emits 9 to be fixed tightly on the central axis 8 with flange assembly 18 by the central axis spiral shell.Open axle 26 and be provided with unlatching gear 3 and driven gear 4 and open handle 17 outward, emit 12 to tighten up by opening the axle spiral shell.Camshaft 5 is provided with cam 21 and end tooth wheel 10.Locking bolt 6 is provided with the locking bolt thrust pin assembly 7 and return spring assembly 13 that is connected with cam 21.
During use; At first mounting holes is installed on the panel of coded lock and opens axis hole at needs; The numeric keypad 15 of protrusion on the lock body 20 is placed installing hole respectively and opens axis hole with unlatching axle 26, with screw lock body 20 is fixed tightly on the panel, coded lock installs and can come into operation.
Next is a password setting: push down password setting button 25, in four row's numerical keys on numeric keypad 15, every row selects a numerical key 23 to press; After four numerical keys 23 are pressed in selection; Unclamp password setting button 25, mess code assembly 19 automatic mess codes, this lock is in the coded lock state; Selected four numerals are unlocking cipher both, and password setting is accomplished.
Unblank: on numeric keypad 15, press selected four digital password, rotate the outer handle 17 of opening, open gear 3 and rotate with driven gear 4; Open gear 3 and 22 engagements of the semi-circle gear of opening plate 2, drive is opened plate 2 and is rotated around central axis 8, and semi-circle gear 22 meshes with end tooth wheel 10; Driving cam 21 rotates; Cam 21 rotating band moving lock bolt thrust pin assemblies 7 promote locking bolt 6 straight lines and move right, and have both opened the first road locking bolt, are rotated further the outer handle 17 of opening; Driven gear 4 rotates opens the second road locking bolt 14, the 3rd road locking bolt 24 successively, unblanks to finish.Unclamp the outer handle 17 of opening, under the effect of return spring assembly 13, locking bolt 6 straight lines are moved to the left, self-return is to the coded lock state.When lock is used for door lock, in the door inward only need be rotated, open handle 16 and can open the door, need not other operation.
