Description

Can change the vane type door lock of key tooth form

The utility model relates to key to be stirred the lock intra vane and drives the door lock that locking bolt moves.

The vane type door lock is the higher vane type door lock of a kind of size of key, 6 plate-like blades of overlapping placement constitute vane group in the lock housing, it is toothed that each blade is provided with a strip at same position, the bar shaped perforation that supplies the locking bolt latch to pass through therein, the perforation of each blade respectively has 4 groups of teeth facing each other, before key is not stirred blade, the teeth of each blade are staggered, and the locking bolt latch can not be advanced; Locking bolt driver plate and blade are stacked together, and the two all is provided with the key poke hole at same position, rotate therein for the spoon wing of key.When key, orthogonal because of the gathering sill direction of the two, blade and driver plate can slide to mutually perpendicular direction.One week of key turns could be taken out by keyhole, rotates for 2 weeks, and teeth cooperate for 2 times with latch, just make the locking bolt driver plate finish whole strokes, reach the purpose of locking and unlatching.Therefore this lockset has higher size of key and safety.But,, have every year a large amount of residents to move house along with the development of social housing condition.Most of resident families employ the fitting-out work personnel earlier and fit up before moving into the new home, and the key of door is transferred to the finishing personnel earlier and grasped, and after handing over key is returned house-owner.The lawless person who has just utilizes this chance, has duplicated the key of door, treat that house-owner moves in after, wait for an opportunity to register one's residence and commit theft, that gives birth to therefrom is happened occasionally by burglar.If exchange new lock, and existing lockset has been enabled just, does not damage, and can cause the waste on financial resources and the material resources.Because the cost of key is cheap relatively, user such as some property firm has proposed the requirement of lockset energy conversion key itself now.Though change the purpose that the lock core blade can reach this lock key of conversion, this kind non-user of operation and those skilled in the art can reach.

The purpose of this utility model provides a kind of vane type door lock that changes the key tooth form, this locks the later stage key of sealing up for safekeeping, house-owner can do to enable the later stage key after simple the adjustment to lockset according to the needs of controlling oneself, early stage, key promptly can not be opened this lock again, can avoid the stolen problem that causes after by bootlegging because of key.

For achieving the above object, the utility model is taked following design scheme: the blade in the lock housing is divided into general blade and standby blade, the total amount of 2 kinds of blades equals the due blade total amount of vane group, standby blade is to offer locating hole at a certain position of blade, the homonymy teeth are contour in the bar shaped perforation, the tooth top line that also is the homonymy teeth should be one with the parallel straight line of bar shaped perforation center line; General blade is then being offered the through-hole type slideway with the locating hole corresponding position of standby blade, and the direction of this slideway is consistent with the blade glide direction; On lock housing, offer standby vanes fixed hole, pass locating hole or slideway on this hole and each blade with screw, standby blade is given positioning and fixing, and its bar shaped perforation gear tip clearance passage should overlap with the latch running orbit on the driver plate, and described screw comprises pin.

The utility model can change the blade door lock of key tooth form, available screw or pin are with standby blade positioning and fixing, general blade is a through-hole type slideway because of what pass above-mentioned screw, and this slideway is consistent with the blade glide direction, thereby can be stirred by key; The tartar of used key and standby blade coupling corresponding position is a neutral gear, make the rotation of key unaffected, and passage can make latch normally pass through between standby blade bar shaped perforation top.This moment, the unlatching and the locking of lockset were undertaken by general blade, and this kind state is the user mode in early stage, and used key is the key in early stage.Early stage, key can borrow other people to use, for interior decoration.After house-owner formally moves in, the screw in the lock housing blade fixing hole is taken off, standby blade is reset to general blade by the power of locking inner spring and overlaps, and lockset is loaded on the door again, and this moment, this lock promptly or else can be key operated with early stage, must enable the later stage key.The later stage key is sealed up for safekeeping in certain container before use, pays in user's hand with lockset when selling, and after enabling, seals the marking up for safekeeping and promptly can destroy.Lockset after later stage key and standby blade reset coupling, its tooth form has been different from the key in early stage, both made with early stage key done to duplicate can not be with this lock unlatching, can prevent the stolen problem that causes after by bootlegging because of key.This lockset is when changing key, and is simple to operate, and the operation of ordinary people's by specification can realize, need not the lockset professional, and do not need special equipment and instrument to accomplish, bring convenience and safe and reliable to the user.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 2 is this lockset blade locating hole place side cut-away view

As shown in Figure 1 and Figure 2, wherein Fig. 1 is for laterally removing standby blade the structural representation of back 2 kinds of blades, the utility model can change the vane type door lock of key tooth form, be that the lock housing intra vane is divided into general blade 8 and standby blade 1, the total amount of 2 kinds of blades equals the due blade total amount of vane group, standby blade 1 is to offer locating hole 2 at a certain position of blade, and the homonymy teeth are contour in the bar shaped perforation 4, also is that homonymy teeth addendum line should be a straight line parallel with bar shaped perforation center line 3; General blade is then being offered through-hole type slideway 9 with the locating hole corresponding position of standby blade, and the direction of this slideway is consistent with the blade glide direction; Offer standby blade locating hole on lock housing 10, pass the locating hole or the slideway of each blade with screw 11, standby blade is fixed, its gear tip clearance passage should overlap with latch 5 running orbits on the driver plate 6.The standby blade of this lockset can be provided with 1-4, when using 2-4 standby blades, for increasing the key spoon amount of key, can make bar shaped perforation 4 both sides teeth have differing heights, also be each standby blade the gear tip clearance passage keep under the prerequisite parallel with bar shaped perforation center line or on move, perhaps move down, and the locating hole 2 of this blade and the distance of perforation center line 3 are adjusted accordingly, so that each blade gear tip clearance passage is in the coincidence shape after whole standby vanes fixed.
