Description

The many locks of single key of the low difficult pirate of the open of reopening rate

The utility model relate to a kind ofly reopen that rate is low, single key many locks, the especially door lock of difficult pirate of the open and big padlock tapered end.

Existing in the market and various utility model patents such as CN2121504U, lock that CN2324249Y and CN2532611Y etc. are related and tapered end, no matter be to adopt traditional saw blade shape key, still adopt cross, prismatic or cylindrical key, all can only open different locks with different keys.Their shortcoming is have what locks what keys are just arranged, thereby people usually to have to when this unblanks with regard to giving, select relevant key to cause certain trouble when especially unblanking at the dark place with a big string key.Simultaneously, because their marble amount is limited, and it is furnished with certain rules, thereby not only reopening rate is higher, and easily by pirate of the open.

The purpose of this utility model provides and a kind ofly reopens that rate is low, more single key of difficult pirate of the open is locked and used tapered end, to eliminate above-mentioned shortcoming and trouble.

The purpose of this utility model is achieved in that all to be drilled with disorderly around tapered end and lock core and is the more pellet shot from a slingshot hole of number.The position in both holes is strictly aimed at.The pellet shot from a slingshot hole of tapered end is isodiametric through hole; In order to increase the quantity of pellet shot from a slingshot as much as possible, and the pellet shot from a slingshot hole of lock core is designed to different diameter hole, the equal diameters in its major diameter and the pellet shot from a slingshot hole on the tapered end.Both center lines all center line with tapered end are vertical.In the pellet shot from a slingshot hole of tapered end, be provided with cylinder-shaped marble and spring; In the pellet shot from a slingshot hole of lock core, be provided with the reducing pellet shot from a slingshot.There is a round key hole in central authorities at lock core.There is a bottom to have a macropore and 2 screw hole, top to have the overcoat on the edge of a wing to prevent that spring and pellet shot from a slingshot from deviating from the outside of tapered end.On the top of tapered end and lock core one top cover is arranged.Its outer rim combines with the flange of overcoat and constitutes a complete tapered end.Its key is cylindrical, is provided with less, the yo-yo waveform protrusion of gradient rib around it disorderly and separates lock pin to promote pellet shot from a slingshot.Its realizes that with the way that progressively increases marble amount and change its position a key opens the purpose of many locks.For example the pellet shot from a slingshot of first lock is 25, and second is 30, and the 3rd being 35, and the 4th being 40 etc.; Concerning the situation that the number of holding key reduces step by step, the position of the pellet shot from a slingshot that lock at different levels increased has nothing in common with each other, thereby pirate of the open mutually.

Come the utility model is further specified below in conjunction with accompanying drawing and example:

Fig. 1 is a tapered end three-dimensional exploded view of the present utility model.

Longitudinal plan when Fig. 2 is the tapered end locking.

Fig. 3 is that the A of Fig. 2 is to view.

Longitudinal plan when Fig. 4 is the tapered end release.

Among the figure 1, overcoat 2, overcoat flange 3, tapered end 4, spring 5, cylinder-shaped marble 6, pellet shot from a slingshot hole 7, lock core tongue 8, lock core protuberance 9, recess 10, pin-and-hole 11, pin 12, bellmouth 13, lock core 14, reducing pellet shot from a slingshot 15, reducing pellet shot from a slingshot hole 16, key positioner recessed 17, circle keyhole 18, top cover 19, circular hole 20, Volume limit 21, cone 22, cylinder 23, key 24, waveform is protruded rib 25, key positioner square 26, key insertion depth backstop 27, the shank of the key 28, key through wires hole 29, screw hole, 30 holes.

In Fig. 1, this reopening rate is low, and the implementation method of the many locks of single key of difficult pirate of the open is: whole tapered end is made up of overcoat 1, tapered end 3, lock core 13 and top cover 18.Overcoat 1 suitable for reading flange 2 is arranged, hole 30 and the screw hole 29 that passes for lock core protuberance 9 arranged at its bottom.After packing into tapered end 3 and lock core 13 wherein, make it tightly encase flange 2 Volume limit 20 bendings of top cover 18 and become the tapered end that complete a Gong door lock or big padlock are used.

In Fig. 2 to Fig. 4, tapered end 3 is a thick cyclinder body, and unordered ground auger full isodiametric perforation pellet shot from a slingshot hole 6 vertical with its center line around it.Lock core 13 also is a thick cyclinder body, also is the full reducing pellet shot from a slingshot hole 15 vertical with its center line of unordered ground auger around it.The quantity in both holes equates, its position is strictly to aim at mutually.The major diameter in reducing pellet shot from a slingshot hole 15 equates with the diameter in pellet shot from a slingshot hole 6.Within reducing pellet shot from a slingshot hole 15 of interpenetrating and pellet shot from a slingshot hole 6, reducing pellet shot from a slingshot 14, cylinder-shaped marble 5 and spring 4 are housed.Lock core 13 has round keyhole 17.Its end has tapering part 12, and has foursquare key positioner recessed 16 at its front end, and the equal diameters of its length of side and circle keyhole 17 is so that the insertion of key and location are with rotational lock core.The end of lock core 13 has the less projection of a diameter 8, and a recess 9 is arranged on it, and lock core tongue 7 is just sold within it by pin-and-hole 10 movably with pin 11.

But the Volume limit 20 of top cover 18 is Volume songs.After overcoat 1, tapered end 3 and lock core 13 with tapered end assemble,, make it tightly encase flange 2 and just become a complete tapered end Volume limit 20 Volume songs position shown in the with dashed lines in the figure.There is a circular hole 19 in central authorities at top cover 18, and its diameter equates with the diagonal of key positioner side recessed 16.At the end of tapered end 32 screw holes 29 fixing usefulness of tapered end when installing is arranged.Key 23 is lived shape part 22, key positioner square 25, key insertion depth backstop 26, the shank of the key 27 and key through wires hole 28 by tapering part 21, circle and is constituted.Around cylinder 22, be provided with that quantity is more, the gradient is less, yo-yo protrusion rib 24.The protrusion height of any point of this rib adds the length with its corresponding reducing pellet shot from a slingshot 14, adds with the length of its corresponding reducing pellet shot from a slingshot 14 with the protrusion height of other any point all to equate mutually.The position of this yo-yo protrusion rib 24, the gradient and protrusion height have nothing in common with each other, and its protruding peak can be unimodal, bimodal or three peaks etc.Look the length on what and slope at protruding peak and different, key 23 is inserted justify keyholes 17 after, each rib can promote 2～5 reducing pellets shot from a slingshot 14 that length is different, and makes lock core 13 releases with key turns.

Its adopts the quantity progressively increase cylinder-shaped marble 5 and reducing pellet shot from a slingshot 14 and the position that changes them and realizes that with the position of the protrusion rib 24 of the corresponding key of pellet shot from a slingshot that is increased and method highly a key opens many purpose of different locks.When for example key is driven four different locks, first lock with 25 pellets shot from a slingshot, second lock with 30 pellets shot from a slingshot, the 3rd lock with 35 pellets shot from a slingshot, the 4th lock with 40 pellets shot from a slingshot etc., like this, this lock not only can be special-purpose for the individual, also can use for the occasion that public passage is arranged.For example, when it is used for building etc. the occasion of multiple tracks door lock is arranged, all can open the key of first sect (for example Lou Dong gate) lock, and except the key that owner held of second sect (for example hall door) lock, the key that other people held all can not be driven the lock at second sect; All can open the key of the 1st～2 road door lock, except the key that owner held of the 3rd sect (for example bedroom door) lock, all can not open the 3rd road door lock; All can open the key of the 1st～3 road door lock, and except the key that owner held of the 4th sect (for example inner room door) lock, the key that other people held all can not be opened the 4th road door lock.Like this, if all relevant personnel that stay in each family in the same unit all with one piece of key just can open belong to he four different locks, and pirate of the open mutually.

The characteristics that this reopening rate single key low, that be difficult to pirate of the open is locked tapered end more are that a key can be opened many different locks. Owing to adopt Cylindrical key, and with a fairly large number of pellet be arranged in disorderly tapered end around, thereby its reopening rate low, be difficult to pirate of the open. It simple in structure is easy to make, and can be widely used in each road of various door locks and big padlock, particularly many household units formula building Door lock.
