Detailed description of the invention

Please refer to shown in Fig. 1 to Fig. 4, it has demonstrated the concrete structure of first embodiment of the utility model, and the padlock in the present embodiment possesses without spoon locking function, after unblanking, key can take off, while locking, do not need to insert key, and can directly lock, only in the time unblanking, need to insert key.This padlock includes lock body 10, U-shaped latch hook 20, lock core 30, card-bit part 40 and bottom 50.

The both sides of these lock body 10 top end faces are respectively arranged with the dog hole 11,12 of longitudinal extension, in lock body 10, between two dog holes 11,12, are provided with accommodating inner chamber 13, and accommodating inner chamber 13 extends downward the bottom face of lock body 10, on lock body 10 bottom faces, forms opening 14; On the positive leading flank of this lock body 10, be provided with cross-perforating 15, this cross-perforating 15 is communicated with aforementioned accommodating inner chamber 13.

Aforementioned U-shaped latch hook 20 is assembled in this dog hole 11,12, and U-shaped latch hook 20 has long hook arm 21 and short hook arm 22, on short hook arm 22 bottom medial surfaces, is provided with hook groove 23.

Aforementioned lock core 30 is installed in this cross-perforating 15, and the lockhole of lock core 30 is laterally outwardly exposed to the positive leading flank of lock body 10, and the tail end of lock core 30 has output revolving shaft 31, and the bottom of lock core 30 is provided with the slot 32 under shed.

Described card-bit part 40 is installed in aforementioned accommodating inner chamber 13, can be laterally movable, and this card-bit part 40 is connected in the output revolving shaft 31 of lock core 30, and it is laterally movable that lock core 30 is controlled this card-bit part 40.Card-bit part 40 includes screens portion 41 and the socket part 42 that one connects, one end of this screens portion 41 and aforementioned hook groove 23 adaptations, the other end of screens portion 41 is butted on a thrust spring 43, is provided with the trepanning 44 being connected with the output revolving shaft 31 of lock core 30 on socket part 42.

Described bottom 50 is packaged in this opening 14 places from bottom to top, convex step 51 and the pin 52 of being provided with of bottom 50, these step 51 supports are in aforementioned card-bit part 40 bottom surfaces, this pin 52 inserts in the slot 32 of aforementioned lock core from bottom to top, utilize this pin 52 to carry out lock core 30 spacing, prevent that lock core 30 from laterally deviating from lock body 10.

In the process using, key inserts in lock core 30, is unblanked by card-bit part 40 retractions that rotarily drive of lock core 30, end lock and turn round key after can extract key, card-bit part 40 stretches out state under the effect of thrust spring 43 in laterally.While locking, do not need to insert key, and can directly press U-shaped latch hook 20, make card-bit part 40 automatic fastenings in the hook groove 23 of the hook arm of U-shaped latch hook, realize rapid, unlocking condition, this card-bit part 40 is deviate from aforementioned hook groove 23.

Please refer to shown in Fig. 5 and Fig. 6, it has demonstrated the concrete structure of second embodiment of the utility model, the structure of the present embodiment and aforementioned the first embodiment is basic identical, difference is the difference of its retaining structure, make the present embodiment and need to insert key when unblanking, it also needs to insert key in the time locking.

Particularly: on the bottom medial surface of described short hook arm 22 and long hook arm 21, be provided with respectively hook groove 23, on output revolving shaft 31 end faces of described lock core 30, be provided with two eccentric projection 33; Two card-bit parts of described card-bit part 40 for being symmetrical set each other, this card-bit part 40 includes one and connects and L-shaped screens portion 41 and socket part 42, the screens portion 41 of two card-bit parts 40 respectively with hook groove 23 adaptations of aforementioned short hook arm 22 and long hook arm 21, the socket part 42 horizontal expansion tail ends of two card-bit parts 40 are respectively arranged with the strip trepanning 45 being connected with aforementioned two eccentric projection 33.

In the process using, drive two card-bit parts 40 to realize horizontal telescopic movable by lock core 30, when two card-bit parts 40 are when protruding, it is sticked in the hook groove 23 on the hammerlock of U-shaped latch hook, and when two card-bit parts 40 are inwardly after retraction, it detaches hook groove 23 and release.After lock core 30 in the present embodiment drives two card-bit parts 40 to expand and stretch out and open to both sides, two card-bit parts 40 can automatic retracted in the time locking, therefore, the retraction process of two card-bit parts 40 still needs to insert key and realizes by rotational lock core 30, and the present embodiment does not possess without spoon locking function.

In sum, design focal point of the present utility model is, it is by arranging via hole on the positive leading flank in lock body, lock core is horizontally installed in this via hole, lockhole can laterally outwardly be exposed to the positive leading flank of lock body, can directly find intuitively lockhole at the positive leading flank of lock body, and the lock body that need not overturn gets on to find lockhole at the bottom face of lock body when people use, make to unblank more directly easy, bring the convenience in use.And, it is by the lower surface opening of lock body, utilize bottom to seal this opening, associated components is all assembled from bottom to top in lock body, and the assembling and positioning structure of internal part can arrange on bottom, not only simplify lock body product structure, facilitate moulding to make, and, facilitate the production and assembly of each parts, improving product production and assembly efficiency greatly, reduces product cost.

The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore any trickle amendment, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
