The utility model relates to a linkage padlock, which comprises a lock shell and a lock core and a blade structure which are arranged in the lock shell, wherein the lock shell comprises an outer lock shell and an inner lock shell positioned in the outer lock shell; the inner lock shell can slide relative to the outer lock shell; the lock core and the blade structure are arranged in the inner lock shell; a spring is arranged between the outer lock shell and the inner lock shell; a connecting block is arranged on the end part of the lock core; one end of the connecting block is positioned in the inner lock shell and is connected with the lock core, and the other end of the connecting block penetrates out of the inner lock shell and is connected with the tail part of a spring bolt; the head of the spring bolt extends out of the outer lock shell and is provided with a clamping block; and a limit bulged shoulder is arranged on the middle part of the spring bolt. The linkage padlock has the advantages that due to the adoption of the structure, the spring bolt can extend out when a door is locked, and can be retracted when the door is unlocked, so that the linkage padlock is simple in structure, convenient to use and low in cost.

Description

A kind of interlock padlock
Technical field
The utility model relates to a kind of field of lockset, relates in particular to a kind of interlock padlock.
Background technology
Existing lockset mainly comprises lock shell and the lock core and the blade construction that are positioned at this lock shell, and the end of said lock core is provided with dead bolt, and the end of this dead bolt is stretched out outside the said lock shell and is formed with fixture block.Lockset in use, key, lock core drives dead bolt and rotates, the fixture block on the dead bolt is stuck on the door and window after rotating 90 degree, realizes locking.When unblanking, only need the backward rotation key to get final product.The lockset of this structure does not have Telescopic, makes structure bigger, and cost is high.
Summary of the invention
Have above-mentioned deficiency in the prior art in order to overcome, the utility model provide a kind of simple in structure, have Telescopic and an interlock padlock easy to use.
The technical scheme that the utility model solves its technical problem is: a kind of interlock padlock; Comprise lock shell and the lock core and the blade construction that are positioned at this lock shell; The inner lock shell that said lock shell comprises outer lock shell and is positioned at this outer lock shell, this inner lock shell can slide by said relatively outer lock shell, and said lock core and blade construction are installed in the said inner lock shell; Be provided with spring between said outer lock shell and the said inner lock shell; The end of said lock core is provided with contiguous block, and an end of this contiguous block is positioned at said inner lock shell and links to each other with said lock core, and the other end of this contiguous block passes said inner lock shell and links to each other with the afterbody of a dead bolt; The head of said dead bolt stretches out outside the said outer lock shell and is provided with fixture block, and the middle part of said dead bolt is provided with spacing convex shoulder.
Further, the end end face towards said fixture block of said outer lock shell is provided with a fluting, and the shape of this fluting and the shape of said fixture block are suitable, and said fixture block can be accommodated in the said fluting.
Further; The afterbody of said dead bolt is provided with installing hole, and this installing hole is provided with the pin-and-hole that runs through, and said contiguous block stretches in the said installing hole and is provided with and the corresponding through hole of said pin-and-hole; Be provided with a barrel bolt in the said pin-and-hole, this barrel bolt passes said pin-and-hole and places in the said through hole.
Further, said outer lock shell is provided with decoration ring outward, and is more attractive in appearance.
The utility model inserts key in the lock core when locking, promote key then, moves relative to outer lock shell thereby drive inner lock shell; Spring is compressed, and the lock core in the inner lock shell drives dead bolt through contiguous block and stretches out, when stretch out put in place after key; Rotate thereby drive lock core, lock core drives contiguous block and rotates, after contiguous block drive dead bolt rotates 90 degree; Fixture block on the dead bolt is stuck on the door and window, and the location convex shoulder on the dead bolt is stuck on the end face of outer lock shell, realizes locking a door.In the time of need unblanking, the backward rotation key, after rotateing in place, the location convex shoulder no longer is stuck on the end face of outer lock shell, inner lock shell travelling backwards under the effect of spring, thus drive the lock core travelling backwards, thus drive the dead bolt withdrawal, realize opening the door.
Because the end face of outer lock shell is provided with fluting, the fixture block of dead bolt can be accommodated in when travelling backwards in the fluting, saves the space.Because dead bolt is connected through barrel bolt with contiguous block, and is easy for installation.
The beneficial effect of the utility model is: adopt said structure, dead bolt can stretch out when locking a door, and when opening the door, can withdraw, and makes simple in structurely, easy to use, and cost is low.
Description of drawings
Fig. 1 is the exploded perspective view of the utility model.
Fig. 2 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain.
With reference to Fig. 1, Fig. 2; A kind of interlock padlock comprises lock shell and the lock core 1 and the blade construction 2 that are positioned at this lock shell, the inner lock shell 4 that said lock shell comprises outer lock shell 3 and is positioned at this outer lock shell 3; This inner lock shell 4 can slide by said relatively outer lock shell 3; Said lock core 1 is installed in the said inner lock shell 4 with blade construction 2, is provided with spring 5 between said outer lock shell 3 and the said inner lock shell 4, and the end of said lock core 1 is provided with contiguous block 6; One end of this contiguous block 6 is positioned at said inner lock shell 4 and links to each other with said lock core 1; The other end of this contiguous block 6 passes said inner lock shell 4 and links to each other with the afterbody of a dead bolt 7, and the head of said dead bolt 7 stretches out outside the said outer lock shell 3 and is provided with fixture block 8, and the middle part of said dead bolt 7 is provided with spacing convex shoulder 9.
End end face towards said fixture block 8 of said outer lock shell 3 is provided with a fluting 10, and the shape of this fluting 10 and the shape of said fixture block 8 are suitable, and said fixture block 8 can be accommodated in the said fluting 10 the saving space.
The afterbody of said dead bolt 7 is provided with installing hole 11; This installing hole 11 is provided with the pin-and-hole 12 that runs through; Said contiguous block 6 stretches in the said installing hole 11 and is provided with and said pin-and-hole 12 corresponding through holes 13; Be provided with a barrel bolt 14 in the said pin-and-hole 12, this barrel bolt 14 passes said pin-and-hole 12 and places in the said through hole 13, and is easy for installation.
