Abstract
Disclosed is a lock-key combined structure which includes a lock casing, a plug, a linkage plate and a buckling ring; wherein the lock casing is provided with an inner hole for containing the plug; a key hole is arranged on one end of the plug and a plurality of grooves and a circular groove are arranged on the other end of the plug; the linkage plate is provided with a plurality of projections tightly inserted into the corresponding grooves of the plug, both the grooves and the projections form a whole body without free sliding and rotating, the outside diameter of the linkage plate is less than the inside diameter of the inner hole of the lock casing; the buckling ring is buckled in the circular groove, and the plug is pivoted into the inner hole of the lock casing. When a pin ball is abraded or the plug is out of work, the plug can be made out for replacing the plug element or pin ball while the linkage plate needs not to be picked up. The utility model has the effect of convenient assembly, time and labor saving and extended service life of the lockset.
Description
Technical field
The utility model relates to the combination of key, refers to a kind of interlock plate that do not destroy especially, just can change the key composite construction of lock core element or pin pearl easily.
Background technology
Referring to Fig. 1, the lock core element of commonly using 9 is positioned at lock housing, and put clasp 91 at lock core 9 ends, again interlock plate 90 is incorporated into the end of lock core 9 in the pressing mode, when needs are changed lock core element 9 or pin pearl, after interlock plate 90 destructions with lock core 9, again clasp 91 is unloaded earlier, could withdraw from lock core element 9.Therefore, the lockset of commonly using often will be pried open interlock plate 90 with making a great fuss when changing lock core element 9, not only can cause many troubles and time-consuming, also can injure lock housing because of carelessness in prying open process, makes the lockset lost of life.
Summary of the invention
The purpose of this utility model is to provide a kind of key composite construction, when pin pearl wearing and tearing or lock core have fault, do not need to pry open interlock plate, just can easily lock core be withdrawed from, change lock core element or pin pearl and key, the effect that it has easy to assembly, saving of work and time and prolongs the lockset life-span.
The technical solution of the utility model: a kind of key composite construction comprises; One lock housing is provided with an endoporus of ccontaining lock core; One lock core, an end of this lock core is provided with a keyhole, and the other end is provided with several grooves and an annular groove; It is characterized in that: an interlock plate, be provided with the several projections of tight plug-in card in each corresponding lock core groove, the two becomes the moving one of can empty not trackslipping, and the external diameter of this interlock plate is less than the internal diameter of lock housing endoporus; One clasp is snapped in the annular groove of this lock core, and this lock core is articulated in the lock housing endoporus.Wherein:
Being respectively equipped with on described lock housing and the lock core can ccontaining several lower pin pearl, on sell the corresponding pin pearl hole of pearl and flexible member, and cover by a pin Zhu Gai and to form one.
The utility model is because the projection that the interlock plate diameter is provided with less than locking shell hole internal diameter and interlock plate, be convenient for changing lock core and can prevent to produce between interlock plate and the lock core the empty effect of sliding phenomenon and have, when pin pearl wearing and tearing or lock core have fault, do not need to pry open interlock plate yet, just can easily lock core be withdrawed from, change lock core element or pin pearl and key, so have easy to assembly, the saving of work and time and the effect in prolongation lockset life-span.
Description of drawings
Fig. 1, for commonly using the sectional view of key combination.
Fig. 2, be three-dimensional exploded view of the present utility model.
Fig. 3, be assembled sectional view of the present utility model.
Fig. 4, change the sectional view of lock core for the utility model.
The specific embodiment
Referring to Fig. 2,3, a kind of key composite construction mainly comprises: a lock housing 1 and a lock core 2, lock core 2 place the hole 10 interior combinations of lock housing 1.
Be respectively equipped with pin pearl hole 11,21 on lock housing 1 and the lock core 2, can supply lower pin pearl 12, on sell pearl 13 and flexible member 14 is inserted in these pin pearl holes 11,21, and cover with pin pearl lid 15 and to form a lockset.
The front end of lock core 2 is provided with keyhole 20, end is provided with several grooves 22 and an annular groove 24, one interlock plate 23, be provided with the several projections 230 of tight plug-in card in each corresponding lock core groove 22, make the rotation of can combining closely of interlock plate 23 and lock core 2, slide phenomenon and be difficult for taking place producing between interlock plate 23 and the lock core 2 sky, and the external diameter of this interlock plate 23 must be less than the internal diameter in the hole 10 of lock housing 1, and be placed on the annular groove 24 by clasp 25, lock core 2 is articulated in the hole 10 of lock housing 1, lock core 2 can't be unloaded from lock housing 1.
Referring to Fig. 4, desire with lock core 2 when lock housing 1 unloads, key 3 need only be injected the keyhole of lock core 2, because the tooth 30 of key 3 and lower pin pearl 12 engagements can not be stuck in the pin pearl hole 11,21 lower pin pearl 12 and last pin pearl 13, clasp 25 is unloaded can interlock plate 23 not unloaded again, just lock core 2 can be unloaded from lock housing 1, when unloading, as long as with pipe 26 lock core 2 and key are released from the hole 10 of lock housing 1 together, this manages the internal diameter that 26 external diameters are slightly smaller than the hole 10 of lock housing 1; Therefore, selling pearl 13 on can rest in the pin pearl hole 11; After having changed lower pin pearl 14 and key 3, will manage 26 with lock core 2 and from the hole 10 of lock housing 1, release, be placed on annular groove 24 with clasp 25 again and get final product.
Because the interlock plate diameter is provided with projection less than locking shell hole diameter and interlock plate, make to the utlity model has the effect that is convenient for changing lock core and can prevents to produce between interlock plate and the lock core empty sliding phenomenon.
