The specific embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, cylinder lock of the present utility model, it comprises key 1, lock housing 2, tapered end and the device that undoes the lock.
As shown in Figure 4 and Figure 5, the key 1 of cylinder lock of the present utility model comprises main body 10 and afterbody 20, and described main body 10 comprises first surface 101, second surface 102, first side 103 and second side 104.The cross section of the main body 10 of described key 1 is a waveform, and this cross section is made up of three arc wave bands.Wherein have on the first surface 101 at the bottom of arc top and two arcs, and corresponding, have two arcs to push up on the second surface 102 and arc at the bottom of.Part as the main body 10 of key 1, first side 103 of described main body 10 is provided with first key bit 1031, the arc top of the first surface 101 of described main body 10 is provided with second key bit 1011, and the arc top near first key bit 1031 on the second surface 102 of described main body 10 is provided with the 3rd key bit 1021.Described first key bit 1031, second key bit 1011 and three key bits 1021 all distribute along the length direction of main body 10.
As a kind of improved embodiment, (promptly at the bottom of the 3rd arc 1022) is on same straight line at the bottom of the arc at the bottom of two arcs on the first surface 101 of the main body 10 of described key 1 on (promptly at the bottom of first arc at the bottom of 1012 and second arc 1013) and the second surface 102.
As shown in Figure 1 to Figure 3, the tapered end of cylinder lock of the present utility model, this tapered end and above-mentioned key 1 are complementary.This tapered end comprises lock body 11, be provided with the lock core 12 of keyhole 121 and respectively with the main body 10 of above-mentioned key 1 on the pellet shot from a slingshot assembly that is complementary of first key bit 1031, second key bit 1011 and the 3rd key bit 1021.Described lock body 11 is fixedly mounted in the lock housing 2 by steady pin 16.Described lock core 12 rotatable being linked in the lock body 11, the lower end edge circumferencial direction of this lock core 12 is provided with the jump ring groove, this jump ring groove is built-in with jump ring 17,12 of described lock cores by jump ring 17 axial limitings in lock body 11.The shape of cross section of the main body 10 of the shape of cross section of keyhole 121 and above-mentioned key 1 is complementary on the described lock core 12.The pellet shot from a slingshot assembly that is located in addition in the tapered end is three row.Obviously, described three row pellet shot from a slingshot assemblies respectively with the main body 10 of key 1 on first key bit 1031, second key bit 1011 and the 3rd key bit 1021 corresponding one by one.
As a kind of improved embodiment, described every row pellet shot from a slingshot assembly is formed by seven groups of pellet shot from a slingshot groups, and described every group of pellet shot from a slingshot group is made up of a spring 13, a locking pellet shot from a slingshot 14 and a movable pellet shot from a slingshot 15 respectively.Have in the tapered end like this and form three row pellet shot from a slingshot assemblies by 21 groups of pellet shot from a slingshot groups, according to general knowledge as can be known, the teeth of each key bit that the length direction of the main body 10 upper edge main bodys 10 of key 1 distributes also just are respectively 7.
As routine techniques, in lock body 11, also be provided with guide peg 18, the sidewall of lock core 12 is provided with the gathering sill (not shown), by the match rotational angle of incompatible control lock core 12 of guide peg 18 and gathering sill, avoids lock core 12 unnecessary rotating distance to occur.
As depicted in figs. 1 and 2, the device that undoes the lock of cylinder lock of the present utility model, the structure of this device that undoes the lock is as follows: the blade 3 of unblanking of the described device that undoes the lock is fixedlyed connected with above-mentioned tapered end, is meant that in fact the lower end of the lock core 12 of the upper end of the blade 3 of unblanking and above-mentioned tapered end welds together.The two ends of the described blade 3 of unblanking are fixed with safety pole 5 up and down respectively, the described safety pole 5 up and down that fixedly is meant of wherein said safety pole 5 up and down is provided with annular groove, and the two ends of the blade 3 of unblanking just are connected in the annular groove of safety pole 5 up and down, thereby realize that safety pole 5 up and down is fixed on the two ends of the blade 3 of unblanking.Described safety pole 5 up and down offsets with the lock pin up and down 6 that is movably combined in the lock housing 2 respectively.The other end of described up and down lock pin 6 can plug together respectively on lock 4 in the low groove, and described lock 4 is movably combined in the lock housing 2.Certainly when locking-in state, the other end of lock pin 6 then plugs together respectively on lock 4 in the low groove up and down, and when opening, the other end of lock pin 6 then breaks away from the last low groove of lock 4 up and down.Also be fixed with on the described up and down lock pin 6 can be unblanked blade 3 extruding with outward winding safety pole 5 up and down and up and down lock pin 6 be pulled away from the pressure-bearing extensible member 7 of lock 4 grooves.Described pressure-bearing extensible member 7 is fixed on up and down and is meant on the lock pin 6, and described lock pin 6 up and down is provided with annular groove, and described pressure-bearing extensible member 7 then is connected in this annular groove, thereby realizes fixing.Also be provided with back-moving spring 8 between described pressure-bearing extensible member 7 and the lock housing 2.
As shown in Figure 2, described pressure-bearing extensible member 7 is flute profile, this pressure-bearing extensible member 7 be two parallel vertical limits and with this two vertical edge be 90 the degree connect as one another side constituted.The right vertical edge of this pressure-bearing extensible member 7 (this orientation refers to orientation as shown in Figure 2) is fixed on up and down on the lock pin 6.The inside wall of the left vertical edge of this pressure-bearing extensible member 7 (this orientation refers to orientation as shown in Figure 2) is a pressure-bearing surface.The left vertical edge of this pressure-bearing extensible member 7 (this orientation refers to orientation as shown in Figure 2) also is equipped with spring base 9, in the described lock housing 2 guider screw 10 is installed, one end of described back-moving spring 8 is set on the guider screw 10, and the other end of described back-moving spring 8 is set in the spring base 9.
Key 1 of the present utility model is same as the prior art with the open theory of tapered end, so not at this detailed description.
During locking, after lock 4 pressed,, thereby lock 4 is pinned because the effect of back-moving spring 8 makes up and down the end of lock pin 6 plug together on lock 4 in the low groove.After treating that cylinder lock is locked, under the situation that does not have key 1, some stealers just can't make the device that undoes the lock be unlocked, thereby have effectively ensured the safety of cylinder lock of the present utility model.
In the time of need unblanking, be inserted into key 1 in the keyhole 121 and clockwise rotate key 1, key 1 drives lock core 11 rotations, and lock core 11 also drives the blade 10 of unblanking and rotates simultaneously.The blade 10 extruding pressure-bearing extensible members 7 of unblanking of rotation, safety pole 5 is outwarded winding about making, and while pressure-bearing extensible member 7 lock pin 6 up and down is pulled away from lock 4 grooves, thereby lock 4 is opened.
Adopt the security performance of cylinder lock of above structure higher, do not having under the situation of key, some stealers can't be opened this cylinder lock.
In the above-described embodiments, preferred forms of the present utility model is described, obviously, under utility model of the present utility model design, still can be made a lot of variations, as the variation of the group number of pellet shot from a slingshot group.Should illustrate that any change of being made all will fall in the protection domain of the present utility model under utility model design of the present utility model.
