Description
Technical field
The present invention relates to a kind of lockset.
Background technology
Lockset has generally comprised lock core, key and fixed cover, and lock core is rotatably arranged in fixed cover, and confession is provided with lock core
The key channel that key is axially inserted into along it, while the blade assembly extended in key channel can be also provided with lock core, from
And only correct key can be inserted into key channel, but because existing blade component structure is excessively simple, from
And make it that criminal is easy to copy out corresponding key, theftproof performance is poor.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of more preferable lockset of theftproof performance.
To achieve the above object, the invention provides a kind of lockset, lock core, key and fixed cover are included, lock core rotates
It is arranged in fixed cover, the key channel being axially inserted into for key along it is provided with lock core, a footpath is additionally provided with lock core
To groove, a positive stop key radially is fitted with described radial groove, the radial outer end of positive stop key is provided with projection, fixed cover
The stopper slot for projection insertion is correspondingly offered on inwall, is provided with lock core along key direction of insertion also linear rows cloth more
Individual blade slot, and each blade slot respectively connects with key channel and radial groove, is inserted in each blade slot
Equipped with start blade, preceding delay blade and after be delayed blade, delay blade and rear delay leaf before described startup blade is folded in
Between piece, the radial inner end of the positive stop key is provided with a convex tendon, and each start is correspondingly arranged on blade for the convex tendon
First slot of insertion, the second slot for convex tendon insertion is correspondingly arranged on before each on delay blade, is prolonged after each
When blade on be correspondingly arranged on the 3rd slot for convex tendon insertion, and the convex tendon on the positive stop key be correspondingly inserted into it is each
After first, second and third slot, the projection on positive stop key is accommodated in radial groove completely, and is separated with the stopper slot on fixed cover,
The spring for forcing it to be passed out of blade slot is also provided between the forward and backward delay blade and lock core, and forward and backward ought be prolonged
When blade passed under the action of the spring out of blade slot after, convex tendon on the positive stop key can not correspond to and be inserted into preceding delay
In 3rd slot of the second slot of blade and rear delay blade, it is correspondingly arranged on described startup blade and extends to key
The first pellet in passage, it is preceding delay blade on be correspondingly arranged on the second pellet extended in key channel, be delayed blade afterwards
On be correspondingly arranged on the 3rd pellet extended in key channel, and the first pellet is correspondingly located at the side of key channel, second,
Three pellets are correspondingly located at the opposite side of key channel, and first, second and third pellet is arranged in isosceles triangle, is correspondingly arranged on the key
Have with the first pellet form sliding coordinate the first key slot, with the second pellet form sliding coordinate the second key slot and
The 3rd key slot of sliding cooperation is formed with the 3rd pellet, and the second pellet sliding on current delay blade enters key
After in second key slot, the preceding delay blade overcomes acting force of the spring to be accommodated in corresponding blade slot；When after delay blade
On the sliding of the 3rd pellet enter in the 3rd key slot of key after, the rear delay blade overcomes acting force of the spring to be accommodated in pair
In the blade slot answered.
The beneficial effects of the invention are as follows：Using said structure, before key insertion, the forward and backward delay blade is in spring
In the presence of can pass outside blade slot, now the convex tendon on positive stop key can not correspond to be inserted into before delay blade the second slot
And in the 3rd slot of rear delay blade, so that the projection on positive stop key can not inwardly bounce back to the radial groove of lock core
Interior, i.e., the projection now on positive stop key is inserted into the stopper slot of fixed cover, thus now lock core can not be relatively fixed set rotation,
It can not unlock.When correct key inserts, first, second and third pellet will slide along first, second and third key slot respectively,
Corresponding pellet sliding enter corresponding to after key slot, corresponding forward and backward delay blade will overcome acting force of the spring, be incorporated in pair
In the blade slot answered, hereafter the convex tendon on positive stop key can be corresponded to and is inserted into each first, second and third slot, described spacing
Key and projection thereon will be also completely retracting in the radial groove of lock core, so that on the projection and fixed cover on positive stop key
Stopper slot separation, now lock core can be relatively fixed set rotation, and then realize unlocking operation.During this, due to the present invention
Be provided with starting in each blade slot blade, preceding delay blade and after be delayed blade, and be separately positioned on start blade,
First, second and third pellet on preceding delay blade and rear delay blade is located at the both sides of key channel respectively, and is arranged in isosceles triangle
Cloth, meanwhile, only correct key insertion can be coordinated by key slot thereon with corresponding pellet, will correspondence blade one by one to
Inside press in blade slot, it is convex on the positive stop key so as to also only all press in blade slot when all blades
Muscle can be completely inserted into corresponding first, second and third slot, and now the projection on positive stop key can just be completely retracting to lock core
In radial groove, this rear lock core can just be relatively fixed set and rotate, and realize and unlock, therefore criminal is difficult to copy out in contrast
The Key structure answered, so as to effectively improve the theftproof performance of lockset.
The present invention can be further arranged to the described corrugated setting of first, second and third key slot, multiple startup blades
On the first pellet, it is multiple before delay blade on the second pellet and it is multiple after delay blade on the 3rd pellet be also in
Corrugated is shifted to install, and a guiding surface for being easy to convex tendon to insert, and every two adjacent first are respectively provided with each first slot
Guiding surface on slot is located at the both sides of convex tendon respectively.By above-mentioned undulatory topology layout, lockset can be further enhanced
Theftproof performance, and in operation, first pellet of first key slot first with starting on blade forms sliding and coordinated, hereafter
With the insertion of key, key is promoted to swing in the presence of guiding surface, consequently facilitating the second pellet is imported into the
In two key slots, and the 3rd pellet imported into the 3rd key slot, to realize that the smooth grafting of wave structure coordinates.
The present invention may further be provided to be used to positive stop key pressing to lock core radially to be additionally provided with described fixed cover
Elastic mechanism in groove, described elastic mechanism include steel ball, compression spring and steady pin, are offered on fixed cover radially
Through hole, the steel ball, compression spring and steady pin are arranged in the radial direction through hole, the both ends of compression spring respectively with steel ball
Abutted against with steady pin, and the steady pin is correspondingly located at the radial outer end of radial direction through hole, and formed admittedly with the radial direction through hole
Fixed, described steel ball is resisted against on the projection of positive stop key.Pass through the effect of above-mentioned elastic mechanism so that spacing bond energy remains
The state being plugged in lock core radial groove, so that after key insertion, under the promotion of the elastic mechanism, on positive stop key
Convex tendon can be automatically inserted into corresponding first, second and third slot.
The present invention may further be provided and be provided with first, second and third key in the positive and negative both ends of the surface for the key
Groove.In this way, not only key positive and negative all can be inserted into, convenient operation, and confusion is had more in structure, effectively
Increase imitation difficulty.
