Description

The mechanical intelligence cylinder lock

The utility model belongs to a kind of door lock, particularly a kind of mechanical intelligence cylinder lock that is suitable for household safety.

In the prior art, adopt the pellet shot from a slingshot technology to make various types of locks more, single, double, four sides multiple tracks pellet shot from a slingshot setting is arranged, as anti-unlocking technique, this lock construction is simple, and cost is not high yet, but in use exists some problems.For example, do not possess the instrument of preventing unlocking function, as long as unblank with suitable instrument, will be opened, this lock does not have antitheft effect; It does not possess recognition function, is hard to tell key and instrument, as long as will very smoothly lock be opened with simple tools; Also do not possess memory function, utilize TO lock after, leave no trace, can also former state lock, owner does not know to lock and was opened by the people.So this billiards lock structure is simple, function is few, and security reliability is poor, and this has limited to a certain extent and has been extensive use of.

The purpose of this utility model is the deficiency that overcomes on the above-mentioned prior art, and existing cylinder lock is improved, and a kind of mechanical intelligence cylinder lock is provided.

The utility model is achieved in that

It has a shell, is equipped with on the shell by handle, and two tongue lock bolts are housed in the shell, and back shroud is equipped with the door lock that tapered end is formed.Outer lock core, internal cylinder, six groups of springs, pellet shot from a slingshot are housed in the described tapered end, and outer lock core is connected with internal cylinder, internal cylinder by dial plate, finger is connected with pair tongue lock bolts.Self-locking spring, pellet shot from a slingshot are housed in the outer lock core, are connected with internal cylinder, 2 stopper rods are housed in the tapered end, 2 stopper rods are connected with coupling by 2 springs, and coupling is connected with connecting rod, and button is housed on the connecting rod.Tapered end is outer to be provided with memory with outer lock core and to indicate.

The utility model compared with prior art has following advantage:

1, has the instrument of the preventing auto-lock function of unblanking.Be provided with self-locking mechanism, utilize any instrument to unblank, all can be locked by self-locking mechanism, lock can not be opened, and has strengthened the security insurance coefficient of lock.

2, has identification key unlocking function.Be provided with the identification key mechanism, key and unlocking tool are had recognition reaction, key unlocking can be opened immediately, unblanks then not open with instrument, plays the effect of distinguishing true from false.

3, has memory function.Be provided with memory sign, to the instrument memory effect of having unblanked, the memory sign can reset when key unlocking, and the memory sign can not reset when instrument was unblanked, and owner judges that according to the memory sign whether lock was opened by the people, had played memory effect.Thereby applied range, not only be used on the household door, also can be used on money box, the automobile or the like.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

As shown in drawings, the utility model has a shell 1, be equipped with on the shell 1 by two tongue lock bolts 3 are housed in handle 2, the shell 1, back shroud 4 is equipped with the door lock that tapered end 5 is formed.Outer lock core 6, internal cylinder 7, six groups of springs 8, pellet shot from a slingshot 9 are housed in the described tapered end 5, outer lock core 6 is connected with internal cylinder 7, outer lock core 6 is not an one with internal cylinder 7, the identification instrumental purpose is arranged, be provided with identification facility circular hole 10 in the internal cylinder 7, instrument can't be stirred internal cylinder 7, is connected with two tongue lock bolts 3 by group plate 11, finger 12, two tongue lock bolts 3 are contained on the support 14, and two tongue lock bolts 3 are connected with keeper 13; Self-locking spring 15 is housed in the outer lock core 6, pellet shot from a slingshot 16 is connected with internal cylinder 7, internal cylinder 7 is provided with and is provided with 2 self-locking holes 18 in 2 half slots 17 and tapered end 5 bodies and is connected, 2 stopper rods 19 are housed in 2 self-

locking holes

18,2 stopper rods 19 are connected with coupling 21 by 2 springs 20, coupling 21 is contained on the support 22, coupling 21 is connected with connecting rod 23, and connecting rod 23 is contained on the support 24, and connecting rod one end is equipped with button 25; With outer lock core 6 arranged outside

memory sign

26,27 is arranged in that tapered end 5 is external, fixing point-blank.

When unblanking with key 28, key 28 inserts outer lock core 6 and enters internal cylinder 7, the corresponding six groups of pellets shot from a slingshot 9 of key teeth, six groups of pellets shot from a slingshot 9 are alignd with the cylindrical of outer lock core 6, internal cylinder 7, key 28 turns right, outer lock core 6, internal cylinder 7 are rotated synchronously, by dialling plate 11, two tongue lock bolts 3 motions of finger 12 drives, open door lock.Rotate and door lock can be locked to anti-direction with key 28.But, unblank and will be restricted with instrument, general unlocking tool L29 shape tool, as the rotational lock core instrument, little hook 30 shape tools are as the hook instrument of moving.When insert outer lock core 6 pellets shot from a slingshot 9 corresponding side inside grooves with the L29 shape tool, and when gently press on the right, inserting outer lock core 6 with little hook 30, internal cylinder 7 is moving six groups of pellets shot from a slingshot 9 of hook back and forth fast, cylindrical pellet shot from a slingshot 9 bore edges and the pellet shot from a slingshot 9 of outer lock core 6 produce friction, locating the friction maximum between the pellet shot from a slingshot 9 up and down, the cylindrical straight line that makes pellet shot from a slingshot go up lower edge outer lock core 6 in 9 minutes separates, outer lock core 6 begins to rotate under the stirring of L29 shape tool, outer lock core 6 is not an one with internal cylinder 7, internal cylinder 7 is not rotated, and is provided with circular hole 10 nothings in the internal cylinder 7 and colludes groove, and instrument can't be stirred internal cylinder 7 and rotate, so lock is not opened, played identification facility and unblanked to act on; As utilize the L29 shape tool to continue to stir outer lock core 6 and rotate, the self-locking pellet shot from a slingshot 16 of dress can laterally move in the outer lock core 6, align the half slot 17 of internal cylinder 7, self-locking spring 15 promotes self-locking pellet shot from a slingshot 16 and enters self-locking hole 18 in tapered end 5 bodies by half slot 17, push up on the stopper rod 19, self-locking pellet shot from a slingshot 16 is not advancing, at this moment self-locking pellet shot from a slingshot 16 afterbodys are in the outer lock core 6, center is in the half slot 17 of internal cylinder 7, head is in the self-locking hole 18 of tapered end 5, has played outer lock core 6 effect of blocking, about all can not rotate, lock has not just thoroughly been opened yet, and plays preventing tool and unblanks to act on; At this moment, not point-blank just at tapered end 5

external memory signs

26,27 with outer lock core 6 arranged outside,

sign

26,27 has misplaced, and has played memory effect; At this moment press button 25, by connecting rod 23, coupling 21, compression spring 20, stopper rod 19, promote self-locking pellet shot from a slingshot 16 compression self-locking springs 15, self-locking pellet shot from a slingshot 16 is got back in the outer lock core 6, again with key 28 twisting outer lock cores 6,

memory sign

26,27 is got back on the straight line, set back, self-locking pellet shot from a slingshot 16 heads withstand on 2 half slot 17 middle parts of internal cylinder 7, self-locking pellet shot from a slingshot 16 no longer ejects, release button 25, and spring 20 drives stopper rod 19, coupling 21, connecting rod 23, button 25 resets, and door lock recovers normal to be used.
