Description

The password assembly insurance institution of mechanical code lock

Technical field

The utility model relates to the password assembly insurance institution of mechanical code lock.

Background technology

Toggle mechanism, the main dead bolt that is connected with toggle mechanism and secondary dead bolt that the existing mechanical coded lock generally comprises the password assembly, cooperates with the password assembly, what have comprises also and the world dead bolt of main dead bolt flexible connection that the name of announcing as CN 2647987Y is called the utility model patent of " push button is from organizing mechanical code lock ".Its toggle mechanism comprises the main switch axle, on the main switch axle, be equipped with the code-bar of stirring the password assembly shifting block, stir main dead bolt shifting block, stir the interlock shifting block of secondary dead bolt, the square cotter of interior outward opening door handle cooperates with the square hole at main switch axle center.Reliable in order to guarantee to open door, opening shifting block takes near the mode that contacts with the code-bar end of password assembly, when opening door password mistake, open shifting block and can not stir code-bar, the householder who has thinks it is loose contact, then continues firmly to rotate the handle that opens the door, and attempts to open door, the result is that door is not opened, and the password assembly then damages because of stressed overstepping the extreme limit.Therefore, need the mechanism that the existing mechanical coded lock is stirred password be improved.

Summary of the invention

The purpose of this utility model provides a kind of password assembly insurance institution of mechanical code lock, and it is reliable that it can guarantee to open door, can prevent stressed the overstepping the extreme limit of password assembly again and damages.

The password assembly insurance institution of mechanical code lock described in the utility model comprises the jam plate of the switch shifting block that is located by connecting on the main switch axle, password assembly and presses torsion spring, it is characterized in that: be provided with safety block between switch shifting block and jam plate.One end of switch shifting block is provided with the profiled holes, the other end that cooperate with the main switch axle and is provided with bayonet socket, first torsion axis and a piece.Safety block is provided with fillet guiding slotted eye of " L " shape and the right angle guiding slotted eye of " L " shape, is provided with one and stirs stake between two guiding slotted eyes; The stake of stirring on bayonet socket on the switch shifting block and the safety block engages.The fillet guiding slotted eye that first positioning guide column passes on the safety block is fixedlyed connected with the jam plate of password assembly; The right angle guiding slotted eye that second positioning guide column passes on the safety block is fixedlyed connected with the jam plate of password assembly.Press torsion spring set on first torsion axis, the one end is pressed against stirring in the stake of safety block, and the other end hangs on the piece of switch shifting block.Owing between the switch shifting block of the jam plate of password assembly and toggle mechanism, be provided with safety block; when password by staggering the time; firmly rotate the main switch axle and drive the switch shifting block; the fillet gathering sill of " L " shape on the safety block promptly produces slip with the positioning guide column that is fixedly connected on the jam plate; make excessive power can not be delivered to the password assembly; thereby protected the password assembly of precise structure, prolonged its application life.

Described mechanical cipher lock cipher assembly insurance institution also comprises second torsion axis and the return torsion spring that are located on the lock box, and the return torsion spring set is on second torsion axis, and the one end is pressed against on the locating rack of password assembly, and the other end hangs on the piece of switch shifting block.With the return torsion spring be contained in the lock box of fixedlying connected on, can the guarantee insurance piece and the cooperation position of switch shifting block and jam plate, and make the accurate return of switch shifting block.

The utility model has the advantages that: simple in structure, easy manufacturing, can prevent stressed the overstepping the extreme limit of password assembly of precise structure and damage, thereby prolong application life greatly, and it is very convenient reliable to open door.Through 60000 tests, the password assembly is excellent.
