Abstract

The utility model relates to a lock head and a padlock which are suitable for lock cores and lock heads of various appearances to make various locks. The keyhole of the lock core is a round hole, and the bottom of the keyhole is in a drill bit shape. The keyhole is communicated with the middle section of a notch on the tail end, which forms a grip clamping hole for the key. A plurality of counterbores of marbles are drilled on the periphery of the lock core and the lock head body randomly to hang the rivet-shaped round head marble or the right cylinder round head marble without falling out of the lock head body. The utility model has the advantages of simple structure, torsion prevention, universal key and high safety.

Description

The round keyhole lock core that can join ten thousand shape keys

The utility model relates to a kind of round keyhole lock core that can cooperate ten thousand type keys, and can bore the pellet shot from a slingshot hole arbitrarily, is fit to the lock core of various external forms, tapered end and the padlock that tapered end is made various locks.

The lock core keyhole of existing cylinder lock, complex structure, the keyhole that is equipped with the corner angle pod does not drop out to hold pellet shot from a slingshot, is easy to stretch into its aperture with super-strength complementary shaped thing pellet shot from a slingshot is turned round sliding twisting off.

The purpose of this utility model provides a kind of simple in structure, and cost is low, anti-turns round, the suitable various key shape of master key, the lock core of various external forms, the round keyhole lock core of tapered end.

The purpose of this utility model is achieved in that lock core keyhole is circular, is drill bit shape at the bottom of the hole, and this side's end face is communicated with the folder mouth that can twist lock core at the bottom of being provided with the drill bit shape hole of notch and stage casing and lock core.In the periphery of different shape tapered end, bore the pellet shot from a slingshot hole by minimum aperture arbitrarily in the middle of the lock core apart from above, and to be counterbore fall less than (referring to Fig. 1, Fig. 2) beyond the tapered end rivet shape round end pellet shot from a slingshot that matches with it to the pellet shot from a slingshot hole on the lock core.

Above-mentioned pellet shot from a slingshot hole can be another kind of counterbore, and pellet shot from a slingshot can be straight cylinder round end pellet shot from a slingshot, makes the low slightly lock of secrecy and uses (referring to Fig. 3).

The corresponding key of above-mentioned round keyhole lock core can be circle, also can be multiple shapes such as square, gives an example 1, cylindrical key: the taper pellet shot from a slingshot that is drilled to that matches with the tapered end pellet shot from a slingshot on cylinder is cheated; Lock core unblank (referring to Fig. 4) is reversed for taper and the front end side of establishing, flat inject folder mouth at the bottom of the lock core circle keyhole in the front portion of cylindrical key; Can establish anterior for frustum of a cone and have the turning round on the sheet (not drawing among the figure) of existing lock that notch is clipped in the notch that inserts in lock core the inner and reverse unblank (referring to Fig. 5).For example 2, square key: all can establish pellet shot from a slingshot hole, slope, groove with the tapered end pellet shot from a slingshot matches on each angle and face, each face bevel of its front end dwindles it, reverses lock core unblank (referring to Fig. 6) thereby insert in folder mouth at the bottom of the lock core circle keyhole.

Other structure of the present utility model and assembling method can be identical with existing tapered end.

The utility model is simple in structure, easy to process, anti-ly turn round, master key, is easy to the key contraposition.

Describe the utility model embodiment in detail below in conjunction with accompanying drawing:

Fig. 1 is a rear elevation of the present utility model.

Fig. 2 is the sectional view of Fig. 1.

Fig. 3 is another sectional view of Fig. 1.

Fig. 4 is the schematic diagram of cylinder key.

Fig. 5 is another schematic diagram of Fig. 4 front portion.

The schematic diagram of Fig. 6 side of being key.

Be drill bit shape 7 and be communicated with into the folder mouth 2 of folder key that referring to key circular hole 3 bottoms of Fig. 1, Fig. 2, lock core 6 rivet shape round end pellet shot from a slingshot 4 hangs in the counterbore 5 of the lock core 6 that is drilled to arbitrarily with notch 1 stage casing of lock core 6 tail ends.

Referring to Fig. 3,8 holders of straight cylinder round end pellet shot from a slingshot are in the another kind of counterbore 9 of lock core 6.

Referring to Fig. 4, be furnished with taper pellet shot from a slingshot hole 11 mutually with pellet shot from a slingshot 4,8 on the cylinder of cylinder key 10, the front end of its anterior taper is unblanked for the folder mouth 2 that side, flat 12 inject lock core 6; Referring to Fig. 5, the front portion also can be frustum of a cone trough of belt mouth 13, makes it be clipped in to reverse on the existing tapered end transmission bar (not drawing among the figure) and unblank.

Referring to Fig. 6, key can adopt the square key as Fig. 6, with all can establish slope bullet groove 15 hole 11 on lock core key circular hole 3 corresponding side's key 14 each angle and the face with pellet shot from a slingshot 4,8 matches, its front end bevel is on demand unblanked its side of dwindling into, flat 12 with the folder mouth 2 that inserts lock core 6.
