The specific embodiment
Be described in detail technical scheme of the present invention for better explaining below in conjunction with the accompanying drawing specific embodiments of the invention.
As shown in Figure 1; Padlock comprises lock body 1, U-shape lock ring 2, tapered end 3, lock ring spacer pin 4, lock ring compressing spring 5, dead bolt 6, dead bolt compressing spring 7, tapered end alignment pin 8, jump ring 9, locking plate 10 undoes the lock; As shown in Figure 3; U-shape lock ring lower end is provided with a breach, and lock ring spacer pin 4 is fixed on U-shape lock ring 2 in the lock body 1.Lock ring compressing spring 5 places the lower end of U-shape lock ring, when padlock is opened, U-shape lock ring 2 upwards ejected in the breach scope, and spacing in lock body by lock ring spacer pin 4.
Like Fig. 4, Fig. 5 and shown in Figure 6; Tapered end comprises inner key cylinder 31, exterior key cylinder 32, lead 33, pellet shot from a slingshot assembly 34, inner key cylinder alignment pin 35; A hollow pellet shot from a slingshot 34b that said pellet shot from a slingshot assembly offsets by the solid pellet shot from a slingshot 34a that offsets with lead 33, with solid pellet shot from a slingshot 34a and an end place the marble spring 34c that the other end and lock body 1 offset in the hollow pellet shot from a slingshot 34b hollow cavity to form; As a kind of improved embodiment, marble spring 34c outer end adopts 12 pairs of pellet shot from a slingshot assemblies 34 of zinc metal sheet to seal fixing.Lock body 1 has the common riveted joint of shrinkage pool 32a that through hole and outer lock core 32 have tapered end alignment pin 8 is arranged.
Exterior key cylinder 32 lower ends have an annulus end plate; Said inner key cylinder 31 matched in clearance are in exterior key cylinder 32; Said inner key cylinder 31 is provided with exterior key cylinder 32 has a plurality of pellets shot from a slingshot hole 31c that spiral distributes one to one, is that pellet shot from a slingshot hole 31c is in inner key cylinder planar development situation arranged evenly shown in Fig. 6.Lead 33 is flush-mounted in inner key cylinder 31 inner ends and has inner key cylinder alignment pin 35 fixing; Form keyhole 31a between lead 33 and the inner key cylinder 31; Keyhole 31a inwall is provided with direction recess, and the annular endplate that described exterior key cylinder 32 has is provided with the corresponding guide recess with direction recess; Inner key cylinder 31 inner end circumferencial directions are provided with jump ring groove 31b; Inner key cylinder 31 is provided with the groove 33a that connects inner key cylinder 31 and lead 33 vertically with setting-in lead 33 inner ends within it; An end that opens and closes locking plate 10 is fixed in the groove 33a by jump ring, and the other end inserts between the dead bolt 6.
Like Fig. 7, Fig. 8, shown in Figure 9; Key comprises head 13 and afterbody 14; Head 13 is provided with a guiding raised line 13b and guiding cavity 13e; Be provided with a breach 13c between the rear end of guiding raised line 13b and the afterbody 14, key head 13 outer peripheral faces are provided with the key shrinkage pool 13a one to one with inner key cylinder pellet shot from a slingshot hole 31c.As a kind of embodiment preferably, be provided with spring 13d in guiding cavity 13e bottom, spring 13d can prop up the outer end of lead 33 when key inserts the padlock keyhole, the extracting of Key.
During locking, after U-shape lock ring 2 pressed, because dead bolt 6 is ejected in the effect of dead bolt compressing spring 7; Thereby the U-shape lock ring lock is lived, and owing to the effect of marble spring 34c, solid pellet shot from a slingshot 34a and hollow pellet shot from a slingshot 34b are ejected simultaneously; Hollow pellet shot from a slingshot 34b blocks inner key cylinder 32 can not rotate, and insert non-valid key and unblank this moment, because solid pellet shot from a slingshot 34a can not overlap with the contact surface of lock core 32 with contact surface and the inner key cylinder 31 of hollow pellet shot from a slingshot 34b; Lock core 32 can't rotate, and can not open padlock.
In the time of need unblanking; The key of coupling is inserted keyhole through the recess that has on the exterior key cylinder annular endplate; Solid pellet shot from a slingshot 34a in groove 13a and the inner key cylinder 31 is corresponding one by one on the key, and solid pellet shot from a slingshot 34a is overlapped with the contact surface of lock core 32 with contact surface and the inner key cylinder 31 of hollow pellet shot from a slingshot 34b, just turns key at this moment; Key drives inner key cylinder 31 and rotates and drive 10 actions of keying locking plate with lead 33, thereby opens padlock.
As a kind of improved embodiment; Described pellet shot from a slingshot group is fixed without zinc metal sheet 12; But the outer end of exterior key cylinder is provided with the bulge loop that exceeds 0.3mm than the inner, and exterior key cylinder 31 inner end excircles are twined by adhesive tape 36, and described adhesive tape is spacing in the 31c of pellet shot from a slingshot hole with the pellet shot from a slingshot group.
In the above-described embodiments; Preferred forms of the present invention is described, obviously, under inventive concept of the present invention; Still can make a lot of variations; As being to adopt jump ring that one end of the locking plate that undoes the lock is fixed on inner key cylinder and the lead among the described locking plate embodiment that undoes the lock, also can adopt the alignment pin riveted way to fix, and for example the alignment pin that fixedly adopted of tapered end and lock body has carried out the fixing fixed form that also can adopt a plurality of alignment pins or adopt other.Should explain that any change of under inventive concept of the present invention, being made all will fall in protection scope of the present invention.
