Description
[technical field]
The utility model relates to a kind of lockset.
[background technology]
Lockset uses very extensively in people's daily life, and the pattern of lockset is a lot, and its critical piece is lock core and the key that matches with it, and key is generally in-line, has pellet shot from a slingshot, spring etc. in the lock core, but the anti-technical opening poor performance of the lock core of this kind lockset.
[summary of the invention]
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of anti-technical opening performance strong lockset.
For solving the problems of the technologies described above, the utility model takes following technical scheme to finish:
A kind of lockset, comprise key and lock core, lock core is fixed in the lockset overcoat, it is characterized in that: the two sides of described key have curved groove, described lock core comprises lock core copper sheathing and the copper fuse that is located in the lock core copper sheathing, lock core copper sheathing and copper fuse are rotatably assorted, be provided with special-shaped marble in the described copper fuse, safety plug, locking plate, marble spring, the locking plate spring, have the cuboid cavity adaptive in the middle of the described copper fuse with the key insertion portion, each side being provided with a row and can holding the aperture of described special-shaped marble at this cuboid cavity, special-shaped marble is located in this aperture and can slides up and down, described special-shaped marble has projection towards a side of key, this projection and the key side with curved groove over against, and fall in this curved groove, projection end size and this curved groove groove width match, a special-shaped marble side of key dorsad has an opening groove, the below of special-shaped marble is provided with described marble spring, described copper fuse left and right sides face has the cavity that can hold safety plug respectively, safety plug is connected with a side of described locking plate, the opposite side of locking plate is relative with the opening groove of described special-shaped marble, the thickness of locking plate and the width of opening groove match, the two ends of described locking plate are supported by described locking plate spring, the locking plate spring is positioned in the spring eye of described copper fuse side, the position of the corresponding safety plug of described lock core copper sheathing is provided with arc groove, and safety plug contacts with this arc groove under the effect of locking plate spring.Every rejection type pellet shot from a slingshot is provided with three at least.
Adopt the lockset of technique scheme, each special-shaped marble has independently projection and opening groove, projection falls in the curved groove that the key side has, curved groove changes the upper-lower position of special-shaped marble, the position of special-shaped marble opening groove changes thereupon, only when the key that matches inserts fully, about all opening grooves of any rejection type pellet shot from a slingshot could align with corresponding left and right sides locking plate, when rotating the copper fuse, could compress safety plug like this, make locking plate enter opening groove, safety plug just can enter in the cavity of copper fuse side, and the copper fuse is rotated with respect to the lock core copper sheathing, thereby open lockset, the arrangement position of this lockset special-shaped marble in the copper fuse can exchange, and the cryptographic key amount of Chan Shenging is just very big like this, if the key that need not match, and want to adopt technical opening, that will be very difficult.
[description of drawings]
The utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model
Fig. 2 turn 90 degrees view for the A-A section of Fig. 1 revolves
Fig. 3 is a key outline drawing of the present utility model
[specific embodiment]
Accompanying drawing has been represented the technical solution of the utility model and embodiment, further describes each relevant details and operating principle thereof of embodiment below more in conjunction with the accompanying drawings.
With reference to accompanying drawing 1,2,3, this lockset, comprise key 15 and lock core, lock core is fixed on 1 li in lockset overcoat, the two sides of described key have curved groove 11, described lock core comprises lock core copper sheathing 2 and the copper fuse 4 that is located in the lock core copper sheathing, lock core copper sheathing and copper fuse are rotatably assorted, described copper fuse is provided with special-shaped marble 13 for 4 li, safety plug 6, locking plate 5, marble spring 9, locking plate spring 16, have the cuboid cavity 10 adaptive in the middle of the described copper fuse with the key insertion portion, each side being provided with a row and can holding the aperture 3 of described special-shaped marble 13 at this cuboid cavity, special-shaped marble is located in this aperture and can slides up and down, every rejection type pellet shot from a slingshot is provided with four, described special-shaped marble 13 has projection 14 towards a side of key, this projection and the key side with curved groove 11 over against, and fall in this curved groove, projection end size and this curved groove groove width match, special-shaped marble 13 side of key dorsad has an opening groove 12, the below of special-shaped marble is provided with described marble spring 9, described copper fuse 4 left and right sides faces have the cavity 8 that can hold safety plug 6 respectively, safety plug 6 is connected with a side of described locking plate 5, the opposite side of locking plate 5 is relative with the opening groove of described special-shaped marble 12, the thickness of locking plate and the width of opening groove match, when locking plate and all opening grooves of rejection type pellet shot from a slingshot all align, locking plate can free in and out opening groove, the two ends of described locking plate 5 are supported by described locking plate spring 16, the locking plate spring is positioned in the spring eye of described copper fuse side, the position of described lock core copper sheathing 2 corresponding safety plugs 6 is provided with arc groove 7, and safety plug 6 contacts with this arc groove 7 under the effect of locking plate spring 16.The special-shaped marble of above-mentioned lockset is established eight altogether, and differential is fourth gear, and its arrangement can produce i.e. 65536 the size of key of 48 powers, removes out of use number, and size of key can reach about 50000.
When needs are opened above-mentioned lockset, key is inserted lock core, this moment, the projection of special-shaped marble fell in the curved groove of key side, insertion along with key, the position of projection in curved groove produces relatively and changes, the drive special-shaped marble slides up and down, the opening groove upper-lower position that special-shaped marble had also changes up and down thereupon, when key inserts lock core fully, the all opening grooves of the left side one rejection type pellet shot from a slingshot this moment are on the sustained height and with left side locking plate and align, the right one rejection type pellet shot from a slingshot all opening grooves also are on the sustained height and with the right locking plate and align, key at this moment, and safety plug is under the effect of lock core copper sheathing arc groove, promote locking plate and enter opening groove, simultaneously safety plug also enters in the safety plug cavity of copper fuse side fully, then the copper fuse rotate with respect to the lock core copper sheathing, thereby open lockset.
Adopt the lockset of technique scheme,, under the background that the theft protection technology improves constantly at present, will have very realistic meanings because anti-technical opening ability is strong.
