Abstract

The utility model relates to a push-button type mechanical puzzle lock. The utility model is characterized in that a push-button type mechanical cipher and a mechanical lock head are combined into one body. The utility model has the advantages of two mechanisms into one body and dual security. The cipher can be discretionally changed at any time and be kept in security.

Description

Key-type mechanical puzzle lock

The utility model relates to the lockset of touch-tone mechanical cipher.

At present, all kinds of locksets all flood market, and style is various, and good looking appearance for social security, antitheftly played certain positive role, is subjected to people's welcome.In the present lockset, mechanical lock is arranged, the useful key of mechanical lock is opened, and the rotation number that has is opened, and what open with key can only be the maintaining secrecy of simple tapered end, what open with the rotation number can only be the secret of fixed number.This class lockset has used for many years, and market presses for a kind of new varieties of update, has better level security.

The purpose of this utility model provides the lockset that a kind of button-type mechanical password and mechanical spring lock head are combined into one, and collecting two kinds of mechanisms is the advantage that one just has double-security, and password can change arbitrarily at any time.

Technical solution of the present utility model is such, and on the basis of existing lock shell, base plate, tapered end, driver blade, the utility model particularly button-type mechanical password and mechanical lock head is combined as a whole.

A plurality of buttons are arranged on the above shell, and the reseting plate in one of them button and the shell joins, and password locking plate in remaining button and the shell and locking locking plate join.

On the base plate in the shell of the present utility model base is arranged, password locking plate and locking locking plate are housed in the square groove of base, the locking plate both sides are provided with square and inclined-plane, two ends at locking plate are equipped with tower spring and key spring respectively, button is housed on key spring, button can be gone up, in the following movable square hole that is contained in shell, slide plate also is housed on base, slide plate has and the corresponding square groove of locking plate, the pendulum that drives by key rotary locking cylinder and driver blade is equipped with in the base below, two pins are arranged on the pendulum, one end of slide plate is equipped with skateboard spring, skateboard spring makes the pin of slide plate near pendulum, in the middle square groove of base, between two locking plates, be provided with the bevelled reset key of an end, load onto the shuttle-type spring on the reset key, on bifurcation keyboard position, reseting plate is arranged at base, reseting plate has an inclined-plane corresponding with the inclined-plane of reset key one end, back-moving spring makes reseting plate contact with two inclined-planes of reset key, two of base front shroud and back shroud are housed respectively, tapered end also is housed below in shell, pad is housed on the tapered end.

Operating principle of the present utility model is, the button of 0 to 9 Arabic character code and A, B, X, a Y4 English alphabet is housed on the face of shell, what adorn in the Y position is reseting plate, and password locking plate and location locking plate are housed respectively in all the other positions, and locking plate has corresponding square groove.The password locking plate under normal circumstances is in the lock state, and opens when pressing Shi Zewei.The locking locking plate is pressed the next locking that is under normal circumstances for opening.Suppose that code number is X25B9, the password locking plate of then in these positions, packing into, the locking locking plate of then packing in remaining key position.

At first press the bifurcation key during use, make whole keys in the raw, then by all passwords, button is depressed the password locking plate when the compressing tablet button, simultaneously the shuttle-type spring snaps in the square groove on the coded lock sheet, after all passwords were all correctly depressed, the square groove of all locking plates all was on the position in the lock, and slide plate promptly can slide in square groove so.Insert the key rotation then, drive driver blade, drive the pendulum rotation again by driver blade, the driver blade afterbody drives the dead bolt motion of lock.When door is opened, pin in the pendulum backs down slide plate with the rotation of pendulum, when certain position is arrived in skateboarding, the motion of drive reset key, shuttle-type spring in the reset key moves between two locking plates, also be that the shuttle-type spring is thrown off the square groove in the locking plate, when lock is opened, when key returns to the position of insertion, be subjected to the active force of skateboard spring, slide plate resets, and the password locking plate is subjected to the elastic force of tower spring, and reset key is subjected to the active force of back-moving spring to return to the origin-location, and lockset automatically locks state.

Push the wrong a key arbitrarily as the password of lockset own, lockset all is in locking, if misoperation takes place when the input password, then by input more again behind the reset key bifurcation.

Password can be by any layout of user, and method of operating is after earlier removing base plate, to open back shroud again, and the password locking plate is put into code number, and all the other positions, hole locking locking plate of then packing into gets final product, and loads onto back shroud and base plate then.

The utility model has the advantages that mechanical cipher and mechanical spring lock head with button are combined into one, collecting two kinds of mechanisms is the advantage that one just has double-security, and password can change arbitrarily at any time, safe and reliable.

Below in conjunction with accompanying drawing embodiment of the present utility model is described:
