[background technology]

In the world today, the password change of mechanical code lock is fairly simple, substantially be safety by maintaining secrecy of password, once there be people to be aware of it, and understand the Changing Pattern of mechanical code lock, also its password scope has just substantially been grasped, thus this mechanical code lock can be opened in a short period of time, so this mechanical code lock also just loses its due effect, at this moment it protect property safety substantially just by the protective capacities of other lockset.Present mechanical code lock is substantially mutually arranged in pairs or groups with built-in lock (comprising cross key built-in lock, a word key built-in lock and other built-in lock) and is used, and can not use as protection lockset separately as mechanical code lock individuality, the theftproof performance also having mechanical code lock and built-in lock to combine is also not very too high, be difficult to keep out skilled unlocking, and present door lock of registering one's residence all is difficult to the puzzlement keeping out skilled unlocking substantially, be that A level lock is non-anti-theft in the life of reality, skilled unlocking just can be opened a few second easily; B level locks not pick-proof, and skilled unlocking a few minutes also can open.If someone has under the table prepared your key, so you have also only had have selected, if the property having such situation that we occur just is difficult to obtain safety assurance of replacing lockset.

[summary of the invention]

Object of the present invention be just to provide a simple rigid, safe and reliable, change mechanical code lock that is various, that be used alone, the mechanical code lock at family of that is can solely keeping goal.

Design scheme of the present invention is that the password making full use of mechanical code lock changes various feature and the combination of mechanical lock, makes lockset more safe and reliable, guarantees our property safety to greatest extent.The present invention had both improve the degree of safety of lockset, had again low-carbon environment-friendly, low cost, pure mechanical combination, manual feature simultaneously.The present invention is formed primarily of mechanical code lock, spring catch, lock body and other supporter, auxiliary body, is configured with pull bar and spanner is opened simultaneously.

In the present invention, mechanical code lock Fig. 1 is improved by common mechanical code lock and forms, coded lock has four blades respectively: 1-1, 1-2, 1-3, 1-4 (setting forth for four blade mechanism coded locks in the present invention), its Leaf 1-1, 1-2, 1-3 tri-specification shapes are the same, blade 1-4 specification is than other each blade 1-1, 1-2, large 2 millimeters of 1-3, coded lock runner 1-7 is as the driving runner of coded lock, runner rotating shaft 1-6 connects coded lock least significant end blade, other blade is fixed on sharf 1-9, sharf 1-9 is hollow, can through runner rotating shaft 1-6's, the axis hole 1-5 of coded lock end blade is smaller than other blade axis hole, the external diameter 1-8 of coded lock runner has password scale to be also the position of rotating with hand simultaneously.In the present invention, mechanical code lock specifically improves as Fig. 2, Fig. 3, it improves is use screw driven vane to rotate, every sheet blade adds a lot of screw hole, and define two or three screw hole circles, each screw hole cast concentrically circle, in the same circle concentric circles of each blade, screw hole is from distance of center circle from identical, and the screw hole spacing on concentric circles will have some different, any rule is not had to seek yet, its spacing is as (millimeter): 2,2.1,2.3,2.4,2.2,2.7,2.3,2,2.6, can not find its rule.Blade Fig. 2 of the present invention has lock pin draw-in groove 2-1, screw hole 2-2, axis hole 2-3, draw-in groove 2-4 and screw form, the object of draw-in groove 2-4 plays the effect that obfuscation technique unblanks; Lock pin draw-in groove 2-1 is only the effect holding spring catch Fig. 4; The effect of axis hole 2-3 allows blade be through on coded lock sharf 1-9; The effect of screw hole 2-2 is used to change password; The effect of screw is rotated in order to driven vane and is accepted driven vane and rotates, and every sheet blade has a primary screw, it can be fixed in any screw hole on blade.Slightly larger than other outer blade diameter 2 millimeters of initial driven vane Fig. 3, it is arranged on mechanical code lock the tip of the axis, and no matter coded lock is made up of several blades, its position all the time at end as initial driven vane.Initial driven vane has lock pin draw-in groove (3-1,3-2), axis hole 3-4, a screw hole 3-3 and screw form, improvement of the present invention has: (1) removes draw-in groove; (2) screw hole is increased; (3) lock pin draw-in groove is transformed; (4) dihedral grinding off lock pin draw-in groove another side becomes a circular arc 3-5.The effect that initial driven vane is improved is: (1) is removed draw-in groove and is more conducive to blade rotation; (2) effect increasing screw hole 3-3 is the total amount increasing change password; (3) transform lock pin draw-in groove concrete shape one by one the smooth 3-1 of section, one section belong to slowly bending arc shaped 3-2, its effect can make initial driven vane promote spring catch Fig. 4 to depart from lock pin draw-in groove 3-1, and then locking lockset; (4) grind off lock pin draw-in groove another side and form a smaller circular arc 3-5, be more conducive to initial driven vane and rotate, be not easy to be stuck.

Spring catch Fig. 4, as an emphasis of the present invention, connects mechanical code lock and lock body by it, bears the effect of unlatching and locking lock body.Spring catch is made up of upper spring pin 4-1, spring 4-2 and lower spring pin 4-3.Upper spring pin Fig. 5 is mainly by tubular iron pipe 5-1, square iron 5-2 and press down shift fork form, the tubular iron pipe 5-1 that a large stomidium of one stomidium is little, the large 5-4 of one stomidium is in order to mounting spring, the little 5-5 of one stomidium is in order to stop spring, the size of aperture 5-5 will to stop spring and to be advisable through lower spring pin end, its inwall of tubular iron pipe wants unusual light, that be connected with it is one piece of cuboid square iron 5-2, its effect is opened and pins lock body, a screw 5-3 also will be welded in the outside, one end of aperture 5-5, fixedly shift fork is pressed down to facilitate, be fixed on screw 5-3 press down shift fork fixing hole 5-7, then pressing presses down shift fork pressure head 5-6, , upper spring pin is driven to move down, square iron 5-2 has also just moved down, reach the object of indoor unlatching locking bolt, unclamp and press down shift fork pressure head 5-6, pressing down shift fork interlock upper spring pin 4-1 can by spring 4-2 pushed home, the effect of spring Fig. 6 is the opening and closing of maintaining upper and lower spring catch, its effect is extremely important, lockset can pin the support will leaning on it for a long time, less a little than tubular iron pipe 3 millimeters of the size of spring is advisable, the length of spring is preferably 40 millimeter, the elastic force of spring will can push down being advisable of just contraction with a little power of hand, and namely elasticity rate is good, shape Fig. 7 (in Ben Wentu, lower spring pin is easy to distinguish with ink-jet figure and other parts) of lower spring pin, it is by cuboid square iron 7-3, cuboid square iron 7-2 and cylinder 7-5 is formed, the width of cuboid square iron 7-3 is less 1 to 2 millimeter a little than the lock pin draw-in groove on mechanical code lock blade Fig. 2, but larger than draw-in groove 3 to 4 millimeters, such cuboid square iron 7-3 can fall in lock pin draw-in groove 2-1 and can not fall in draw-in groove 2-4, the size of cuboid square iron 7-2 will can not be advisable through spring 4-2 through tubular iron pipe 5-1, and firm welding is wanted in the connection between cuboid square iron 7-2 and cuboid square iron 7-3, its angle is not 90 degree, the welding of cuboid square iron 7-3 wants one end long, the short 7-4 in one end, the angle of short one end will have about 94 degree 7-1, 7-5 cylinder is based on firm reinforcing bar, but want unusual light, thinner a little than spring 3 millimeters of thickness is advisable, end will bore a hole to wear the use of pin 7-6.

Other fixed structure that the lock body that lock body Fig. 8, Fig. 9, Figure 10 refer to here comprises locking bolt push-and-pull hole 8-1, locking bolt 8-2, square bar hole 8-4, pull bar Fig. 9, spanner 13-30, dead bolt hole 10-7, upper lower guide rod drive hole 9-3, square bar hole 9-2, support, the activity of assistance lockset and acts on.Locking bolt 8-2 is one piece of metal cuboid or cylinder, and very firm, unusual light, and the effect of locking bolt 8-2 stretches out dead bolt 8-3 to pin door body; The effect of pull bar 9-1 is push-and-pull locking bolt 8-2, the shape of pull bar Fig. 9: one end is straight hook shape 9-1, one end is copper coin shape 9-2, the effect of straight hook 9-1 is push-and-pull locking bolt 8-2 in hook inserts on locking bolt 8-2 push-and-pull hole 8-1, dead bolt is in and stretches out or retracted mode, copper coin shape 9-1 one end is in order that through square bar, two spanners are connected to square bar two ends, the selection of pull bar Fig. 9 is very solid, weld also very firm, because the brute force that it can afford other people malice is opened, even destroy; Push-and-pull hole 8-1 will very firmly be fixed on locking bolt, because the brute force that it will afford other people malice is opened, its position of 8-1, push-and-pull hole of the present invention adds 20 millimeters of places in the length of dead bolt 8-3, and push-and-pull hole 8-1 has the space of dead bolt 13-23 length at least in lock body, to drive dead bolt to stretch out or to retract, and guarantee that dead bolt can be retracted lock body completely; Spanner 13-30 has two, is indoor spanner and spanner outdoors respectively, and its effect is that rotary spanner drives dead bolt stretch out or retract, and spanner is also very durable, because it will afford other people forceful action maliciously; Dead bolt 13-23 is inserted in the effect of dead bolt hole 10-7 exactly, plays the function of pinning door body; The effect of upper lower guide rod drive hole 9-3 connects lower guide rod exactly, and then drives upper lower guide rod to implement multiple spot pinning; Support, assist other fixed structure that lockset is movable and act on, comprise solid mechanical coded lock 10-4, square bar hole 10-3, two upper spring pin catch 10-1, two lower spring pin catch 10-2, dash areas are that facade steel plate 10-6, several fixing lock body screw hole 10-5 and other lockset support supplementary structure.

General structure of the present invention is as Figure 13, and mechanical code lock is fixed on lower left, spring catch is directly over mechanical code lock, locking bolt is above spring catch, spanner and pull bar are in the right of spring catch, and in figure, various piece respectively: lock pin draw-in groove 13-1, the lock pin draw-in groove circular arc line 13-2 of initial driven vane, outer blade diameter 13-3, the lock pin draw-in groove circular arc 13-4 of initial driven vane, fixed password lock lock body position 13-5, fixed password lock lock body opening 13-6, two lower spring pin catch 13-7, lower spring pin 13-8, two upper spring pin catch 13-9, upper spring pin square iron 13-10, upper spring pin 13-11, spring 13-12, the support member 13-13 of lower spring pin, the pin 13-14 of lower spring pin end, press down shift fork 13-15, 13-16 on the screw being arranged on spring catch pressing down shift fork, the left side, locking bolt push-and-pull hole block body 13-17, locking bolt push-and-pull hole activity space 13-18, locking bolt 13-19, pull bar and hook 13-20, locking bolt push-and-pull hole 13-21, block body 13-22 on the right of locking bolt push-and-pull hole, dead bolt 13-23, dead bolt box fixed screw holes 13-24, dead bolt box 13-25, lock body fixed screw holes 13-26, in structure chart, dash area is that facade fixes lock body parts 13-27, square bar and push-and-pull rod aperture 13-28, upper lower guide rod drive rod 13-29, spanner 13-30.The present invention is relatively simple for structure, with lock pin draw-in groove 13-1 corresponding lower spring pin 13-8, lower spring pin 13-8 falls in lock pin draw-in groove, interlock upper spring pin 13-11 falls, the square iron 13-10 of upper spring pin removes the stop to locking bolt 13-19 immediately, then rotating spanner 13-30 drives pull bar 13-20 to drive locking bolt 13-19, allow in dead bolt 13-23 retraction lock body, other parts generally all help out, following spring catch catch 13-7 is exactly the twisting space of restriction lower spring pin, the left side, locking bolt push-and-pull hole block body 13-17, on the right of locking bolt push-and-pull hole, the effect of block body 13-22 is exactly the moving range in restriction push-and-pull hole, also the moving range of restriction spanner is played.

Technical scheme of the present invention is first by change acquisition one group of coded lock password, being set as of password: (1) unloads plain cushion between four blades of mechanical code lock, blade and a jump ring, (2) screw on each blade is laid down, (3) screw on each blade is arbitrarily installed, (4) order installs blade and plain cushion (now first not installing jump ring), (5) rotational password lock runner 11-5, coded lock runner 11-5 there is 0 graduation mark 11-3, the graduation mark 11-1 of 1 to 99, be fixed on the red line 11-2 on the coded lock fixed disk 11-4 on a body, the effect of red line 11-2 is that scale on corresponding runner is to determine password numerical value, first coded lock runner 11-5 tri-weeks are rotated clockwise, and then slowly rotate and the lock pin draw-in groove observing innermost a slice blade whether just to lower spring pin, [preferably two people coordinate, people's (first) is at rotational password lock runner outdoors, people's (second) examines lock pin draw-in groove in doors and whether lower spring pin is just right, if] just right, first just sees that the red line on coded lock and which the scale correspondence on runner also firmly remember it, then first another mistake hour hands rotational password lock runner two weeks, whether second notes observing the lock pin draw-in groove of several second blade from the inside just to lower spring pin, if just right, first is then observed runner scale and is firmly remembered, next coded lock runner is rotated clockwise again one week, whether second still notes observing the lock pin draw-in groove of several 3rd blade from the inside just to lower spring pin, if just right, first is then observed runner scale and is firmly remembered, last counterclockwise slowly rotational password lock runner again, second notices that whether the lock pin draw-in groove observing driving runner bucket is just to lower spring pin, if just right, first is then noted observing runner scale and firmly remembeing, such one group of new password has just set.Here it is specifically intended that jump ring above is not also loaded onto, this is because but although password produces did not use, disadvantage of the present invention just here, (be perhaps that function is directly proportional to shortcoming, the more problems of function are also more, ) be exactly that some password combination is unworkable on the invention, draw-in groove when namely coded lock runner turns to some positions on blade or lock pin draw-in groove block lower spring pin, such situation is that coded lock runner is stuck or does not open at all coded lock, the solution of this situation is also very simple, it is exactly the screw position which blade which blade card just adjusts on, again test generation new password (occurs that situation is considerably less above again, but have after all, must carefully test), (6) unload initial driven vane, after jump ring is installed, initial driven vane is installed again, (7) new password is put into practice, this process is extremely important, and be that situation about opening at door is carried out, according to the coded lock of setting steps unlatching above, correct password position must be inputted, whether because password of the present invention is arranged, to be confined to units corresponding with red line, or password is not integer, as 21.5 is exactly rotate half-space more 21 time, so test extremely important, the accuracy of noting observing each password during test also adjusts in time oneself remembers password, lower spring pin 12-2 after input password on Figure 12 blade 12-1 directly enters in lock pin draw-in groove 12-3 smoothly, at this moment password is just arranged successfully at last, (8) new password is repeatedly practised, because the Password Input of mechanical code lock of the present invention is more inflexible, a little error all can cause the failure of opening, so the situation will opened at door be repeated, at least practise in my opinion successfully more than ten times better.

Secondly, the operating principle of spring catch is when password does not have entirely accurate, its lower spring pin 13-8 is on the outer blade diameter 13-3 of coded lock, lifted by the blade of coded lock, lower spring pin 13-8 lifts spring 13-12, spring 13-12 lifts upper spring pin 13-11, and the square iron 13-10 of upper spring pin 13-11 blocks the retraction of locking bolt 13-19, material is thus formed the effect of locking.After Password Input is very accurate, lower spring pin 13-8 relies on the effect of gravity automatically to fall into lock pin draw-in groove 13-1 Figure 12, while lower spring pin 13-8 falls, upper spring pin 13-11 also falls owing to not supporting, at this moment spring 13-12 be in seem not have state (the spring 13-12 elastic force in spring catch of the present invention and length all extremely important, elastic force is excessive or too small, the length of length all directly can have influence on the degree of safety of lockset, when reaching locking, spring 13-12 will be in the state of full extension), upper spring pin 13-11 falls the upper spring pin square iron 13-10 that dissolved by itself to the stop of locking bolt 13-19, at this moment can rotating spanner 13-30, spanner 13-30 interlock catch bar 13-20, catch bar 13-20 drives locking bolt 13-19 to move, thus reach the object of opening lockset.If after opening door, also to change the sensing of coded lock runner 11-5 in time, at this moment note will using some strength a little, runner 11-5 is rotated clockwise two weeks (note: now can only rotate clockwise, because lower spring pin 13-8 is also stuck by lock pin draw-in groove 13-1, turn motionless counterclockwise), others does not just know your rearmost password like this, simultaneously lockset has now been in the state of locking completely, namely directly rotating spanner 13-30 the dead bolt 13-23 of locking bolt 13-19 can be stretched out pinning door, also can temporarily not lock, free in and out, directly can reach the object of locking a door by rotating spanner 13-30 at any time.Now the operating principle of lockset is: rotational password lock runner 11-5, the initial driven vane 1-4 slowly jack-up lower spring pin 13-8 of coded lock, mainly lower spring pin 13-8 is in the lock pin draw-in groove 13-1 of initial driven vane, but the lock pin draw-in groove 3-1 of initial driven vane 1-4, 3-2 is an arc shaped, arc shaped is also conducive to initial driven vane and rotates, circular arc line is relied on slowly to promote lower spring pin 13-8 lifting, until lower spring pin 13-8 is lifted on coded lock external diameter 13-3, lower spring pin 13-8 jack-up spring 13-12, spring 13-12 jack-up upper spring pin 13-11, upper spring pin 13-11 connects upper spring pin square iron 13-10, but locking bolt 13-19 now is also in the state of retraction, upper spring pin square iron 13-10 is stopped by locking bolt 13-19, not by jack-up, lower spring pin 13-8 by jack-up, such upper spring pin, the active force of lower spring pin all acts on spring 13-12, spring 13-12 is now owing to being subject to upper spring pin 13-11, the extruding of lower spring pin 13-8 has also just been shunk, so to reach coded lock directly to unblank and the object of locking simultaneously, once the dead bolt 13-23 of locking bolt 13-19 by spanner 13-30 promote stretch out completely after, the top of upper spring pin square iron 13-10 is also just without any stop, the now energy of spring 13-12 also just release rapidly, upper spring pin 13-11 is upspring, upper spring pin square iron 13-10 also just completes rapidly the object stopping locking bolt 13-19, so just pin door.

Usefulness of the present invention is: cost is low, simple rigid, safe and reliable, change various, be used alone without key mechanical code lock, the mechanical code lock at family of that is can solely keeping goal.Cost is low is because can make with iron and steel completely without key mechanical code lock, as long as antirust work is carried out; Simple rigid, the structure being exactly lockset in the present invention is simple, and from outdoors, only have coded lock runner and handle two movable parts, other is all fixing, if there is outside destroy: coded lock runner originally can arbitrarily rotate, and destruction has little significance; Handle is connected on square bar, catch bar, locking bolt, as long as these parts are enough durable, believe and stops that the square iron of locking bolt can allow outside destroy halt.Safe and reliable, it is exactly the technology that the present invention can allow skilled unlocking abandon stethoscope to unblank completely, because initial driven vane is larger than other blade, and lower spring pin lower weld has certain angle 7-1, that is the chance of other three blades of lower spring pin contacts is little, so also just distinguish the meaning to mistake without listening, now only have by other means, if he knows the password before you, just you have changed password, he thinks the password that inference is present, I thinks neither be not all right, but be difficult to, because the screw hole spacing on blade does not have rule, moreover I also will advise that talented people can like this when changing password: the current screw that drives is at outer ring screw hole, next time is at inner ring hole, or inner ring screw hole, outer ring screw hole is used with, believing that at this moment skilled unlocking can open lockset is no longer with minute calculating, but with hour or day to calculate that (I also can only calculate with sky or simply say myself in fact: I does not open yet not know password, so my sincere advice only has one: the more accurately password, the more password is put into practice, and firmly remember password), change various, be exactly that its password quantity that can form is very many, such as: the screw hole that three identical blades can be beaten is a lot, suppose each blade there are two circle screw holes, outer ring is 20, inner ring is 10, screw hole on so every sheet blade has just had 20+10=30, suppose that initial driven vane screw hole has 15+8=23, amount to its number of password and have how many, 30*30*30*23=621000, perhaps actual meeting is fewer than this, but this has also enough used, can precautionary technology unblank like this, be used alone because it does not need other lockset with the use of, so can say that it is the mechanical code lock at family of can solely keeping goal.
