The specific embodiment:

Come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment:

Show the concrete structure of a kind of embodiment of the present utility model referring to figs. 1 through Fig. 5, this padlock 100 comprises a shell 10, and shell 10 is formed by a upper shell 11 and a lower house 12 assembly.The top of upper shell 12 is latch hooks 20 of this padlock.Be provided with lock gall 30 in the shell 10, upper shell 11 is by screw 13 and interior lock gall 30 lockings, and 12 of lower houses lock by screw and interior lock gall 30.For anti-sealing flows in the shell 10 from the top, cause the parts in the shell 10 to get rusty, the utility model is provided with a rubber waterproof sheet 14 between upper shell 11 and interior lock gall 30, and flashing is provided with two and is convenient to the through hole 14a that latch hook 20 passes.For making the utility model more attractive in appearance, on screw 13, adopt plastic cover 15 simultaneously, this screw 13 is stashed.

The both sides of upper shell 11 also symmetry be provided with two latch hook through hole 11a.Certainly, also can be made as the structure of Fig. 9 as the housing 11 on the utility model of needing of pick-proof, promptly the periphery at upper shell 11 adds the protection wall 11b that a circle is encircled at latch hook 20 peripheries.

Latch hook 20 is a U-shaped, and comprises one long-armed 21 and one galianconism 22, and its cross section is circular.What be provided with an arc groove 21a and a whole circle on long-armed 21 inboard colludes groove 21b, collude groove 21b than the close long-armed afterbody of groove 21a, collude and be provided with a slideway 21c between groove 21b and the groove 21a, also be provided with an arc groove 22a in the position relative, the inboard of galianconism equally with groove 21a.

Be provided with a lock core 31, an eccentric rotary piece 32 and two steel balls 33 in the interior lock gall 30.

Wherein, eccentric rotary piece 32 is enclosed within on the commentaries on classics core 31a on the lock core 31, and rotate with changeing core 31a, the cross section of eccentric rotary piece 32 becomes a circle cut surface (with reference to Fig. 4), and form two parallel relatively plane 32a, the 32b arc surface 32cs relative, the distance h in the relative center of circle of its midplane 32a with two ' be greater than the distance h in the relative center of circle of 32b, plane.

In the lock core hole 30a (with reference to Fig. 5) of eccentric rotary piece 32 lock gall 30 downsides in lock core 40 is enclosed within, the upper side of interior lock gall 30 monosymmetric is provided with two latch hook chute 30b, the inboard of two latch hook chute 30b respectively is provided with a short slot space 30c, wherein be used to prevent that near also being provided with on the short slot space 30c of galianconism 22 sides steel ball 33 from falling into the arc retaining wall 30d (with reference to Fig. 8) in the latch hook chute, steel ball 33 is sheathed on respectively in these two short slot space 30c, and is sandwiched between long-armed 21, the galianconism 22 and eccentric rotary piece 32 of latch hook 20; Retaining wall 30d is used to limit steel ball 33 and does not fall in the latch hook chute 30b, can make steel ball 33 expose a part in latch hook chute 30b simultaneously again.

With reference to Fig. 6, Fig. 7 and Fig. 8, show the concrete structure of the utility model two states when unblanking when locking, when locking, the arc surface 32c of the transverse width broad of eccentric rotary piece 32 is adjacent to two steel balls 33 as seen from Figure 6, make in two groove 21a, the 22a of corresponding respectively long-armed 21 and galianconism 22 inboards that embed latch hooks 20 of two steel balls 33, and then reach the limit effect of latch hook 20, promptly firmly be pulled outwardly moveable lock hook 20 and can not spur latch hook 20 and outwards skid off.Invite the commentaries on classics core 31a on the rotational lock core 31 then of to unblank, thereby further driving eccentric rotary piece 32 rotates, after rotating about 90 degree, make the transverse width of eccentric rotary piece 32 less two

parallel plane

32a, 32b towards two steel balls 33, be relative distance of center circle near plane 32b towards galianconism 22 steel ball 33 on one side, the plane 32a of center of circle distance is then towards long-armed 21 on one side steel balls 33 relatively.Reserve two small one and large one activity spaces 35,34 (with reference to Fig. 7) for like this two steel balls 33.

At this moment, firmly be pulled outwardly moveable lock hook 20, long-armed 21, the galianconism 22 of latch hook 20 can promote steel ball 33 and move in two activity spaces 34,35.Bigger because of the activity space 35 of galianconism 22 sides on the one hand, steel ball 33 can wholely shift out the groove 22a of galianconism 22, thereby removed the galianconism 22 that steel ball 33 catches on latch hook 20, the activity space 34 of long-armed on the other hand 21 sides is less, steel ball 33 is when shifting out the groove 21a of long-armed 21 sides, enter in the slideway 21c, and also some steel ball 33 exposes in latch hook chute 30b.When latch hook continues outwards to slide, make slideway 21c slip over steel ball 33, the groove 21b that colludes on long-armed 21 slides into steel ball 33 positions, the steel ball part of exposing in latch hook chute 30b just in time catches on groove 21b, latch hook 20 can not outwards be slided again, also do not deviate from latch hook chute 30b this moment long-armed 21, and galianconism 22 has been deviate from latch hook chute 30b (with reference to Fig. 8), promptly reaches unlocked conditions.

Assembling process of the present utility model is described below:

At first interior lock gall 30, flashing 14 and upper shell 11 usefulness screws 13 are fitted together, and make the center-aligned of the center of the through hole 11a on the upper shell 11 and the latch hook chute 30b on the interior lock gall 30.Flashing 14 is sandwiched between interior lock gall 30 and the upper shell 11.Then latch hook 20 is inserted in the latch hook chute 30b on the interior lock gall 30 of through hole 11a insertion that passes on the upper shell 11, in the short slot space 30c in simultaneously two steel balls 33 also being packed in the lock gall 30.After installing, in the lock core 31 that will be with eccentric rotary piece 32 is again packed in the lock core hole 30a of lock gall 30 downsides, next the above-mentioned assembly that installs is inserted in the lower house 12, and with screw with lower house 12 locking on interior lock gall 30, cover plastic plate 15 at last, screw 13 is covered, promptly finish the assembling of whole padlock 100.

The dispersed structures of lock galls in the cover one in the shell 10 that focuses on upper shell and lower house assembly are formed of the utility model, make that dismounting is convenient when assembling when the utility model is produced and keeping in repair, also make simultaneously each parts have the flexibility of extremely strong selection and change moulding, reach the purpose that padlock has good interchangeability with this; The utility model is also by being provided with the effect that flashing 14 is realized waterproof between upper shell 11 and interior lock gall 30.

The above, it only is the preferred embodiment of a kind of separate type padlock of the utility model, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
