The utility model comprise have will be in article described below the goods of feature, character and element relation of exemplary illustration, and scope of the present utility model will be described in the claims.

Referring to figs. 1 to Figure 21 and following detailed description, provided two structure and operations of replacing preferred embodiment of key operated padlock 20 of the present utility model, and can understand it best.Accompanying drawing and following open in detail in, preferred embodiment of the present utility model has been described in detail in detail fully.Yet of the present disclosure providing only is purpose for example, because the utility model can be implemented by the replacement structure that adopts other, so all such replacement structures all will be included in the scope of the present utility model.

In Fig. 1 to Figure 19, show a preferred embodiment of the padlock 20 of the critical piece that includes minimum number, thereby obtained key operated padlock, as long as padlock is opened under given conditions, this key operated padlock all provides clear and definite caution, has meanwhile also reduced the complexity that exists in most prior art pad lock structures basically.Like this, the utility model provides very effective, commercially beneficial structure, this structure can be produced with competitive cost, and the customer also is provided the specific characteristic simultaneously desired to padlock, and normally more expensive padlock just have all the locking and antitheft features.

Extremely shown in Figure 19 as Fig. 1, in this preferred embodiment, the J-shaped hook 22 that key operated padlock 20 includes shell 21 and cooperates with shell 21.Hook 22 includes long column 23 and short column 24.In preferred construction, the long column 23 of hook 22 includes the notched region 25 that forms along its length, and at this notched region place, the diameter of long column 23 is much smaller than the diameter of long column 23 other positions.

In preferred structure, shell 21 has comprised the compatible portion 26 and 27 of effective formation shell 21 front and rear parts.Although this structure is preferred, shell 21 can constitute any replacement structure of expectation.

Shown in Fig. 1,3, shell 21 includes end face 28, bottom surface 29 and is formed on elongated channel 30 in the shell 21, and the inlet port 31 of this path 30 from the end face 28 that is formed on shell 21 begins to extend, and terminates in next-door neighbour 29 places, bottom surface in the shell 21.In addition, shell 21 also includes quite short path 32, and it constitutes the short column 24 that is used for linking up with 22 and cooperates, and shell 21 also includes the inlet port 33 in the end face 28 that is formed on shell 21.

In preferred structure, the long column 23 of hook 22 is installed in the path 30 of shell 21 pivotally, simultaneously also can axially motion in path 30.Link up with the axially-movable of 22 post 23 with respect to the path 30 of shell 21 in order to control, path 30 includes and is formed on its inner protuberance 35 and 36, and protuberance 35 and 36 is positioned under the inlet port 31, and matches with the notched region 25 of hook 22.By adopting protuberance 35 and 36, the axially-movable of the post 23 of hook 22 can be restricted to the whole length of notched region 25.

At last, but, spring part 37 is installed on the bottom of path 30, and contacts with the terminal control of the post 23 of hook 22 in order to make hook 22 automatic axial motion when discharging.Like this, as long as hook 22 is when its locking mode discharges (such as will be described in detail), hook 22 can both axially-movable automatically in path 30, but is subjected to the restriction of notched region 25 motions between protuberance 35 and 36.

Key operated padlock 20 also includes housing region 40, and this housing region 40 is formed in the shell 21, and its size is suitable for holding and keep cylindrical outer cover 41 securely.Plunger 42 can prior art in known mode rotational motion in cylindrical outer cover 41 usually.Yet as will be described in detail, plunger 42 constitutes two unique modular constructions, and this makes plunger 42 to be constructed and to assemble with the cost that reduces greatly.

In this embodiment of the present utility model, plunger 42 is in response to cooperate key spare to be inserted into holding tank (it is formed in the plunger 42, and 43 extends to end face 44 from the bottom surface) and rotational motion in cylindrical outer cover 41 always.In addition, the end face 44 of plunger 42 is combined with upright projection 45, and it is fixedly mounted on the surface 44 and from this surface and extends upward.And, as all shown in the accompanying drawings like that, padlock 20 includes elongated spring biasing arm spare 46, it is installed in the shell 21 and upright projection 45 and long column 23 butts of linking up with 22.

As shown in Figure 2, when padlock 20 was in the lock state, spring biasing arm 46 was arranged in the notched region 25 of the post 23 of hook 22.The result with regard to since the position of arm spare 46 stoped and linked up with 22 axially-movable and will link up with 22 and remain on latched position.Yet as long as plunger 42 arcs rotate, the upright projection 45 of the end face 44 of plunger 42 just engages with spring biasing arm 46, and this makes arm 46 therewith outwards move.This motion forces arm 46 to separate with notched region 25, and release shackle 22 effectively, thereby makes hook 22 move to its unlocked position automatically.

According to the utility model, padlock 20 has been constructed two key spares separately and independently.As Fig. 8 and shown in Figure 9, key spare 50 and 51 all constructs and is arranged to cooperate with plunger 42, thereby realizes the required rotation of plunger 42 in cylindrical outer cover 41.

Can see obviously that from Fig. 8 and Fig. 9 the entire length of key spare 50 is longer than key spare 51, and each key spare all includes the incision tract that brake bars a plurality of and in the plunger 42 matches.Key spare 51 constitutes user or possessory key, and the owner of padlock 20 will utilize this key to lock or release padlock 20.In the utility model, the length of key spare 51 is less than key spare 50, and has three incision tract, and key spare 50 has four incision tract.According to the utility model, key spare 50 is represented master key, and as needs, the Security Officer will open padlock 20 with it.Thus, master key 50 constitutes and is used to open a large amount of padlock 20, and separately and independently user's key 51 will be used to open each padlock.

Plunger 42 is except including the holding tank that extends through plunger 42, and plunger 42 also includes a plurality of spring bias voltage brake barses, and the incision tract that forms on these spring bias voltage brake barses and key 50 and 51 matches.As known in the prior art, in this structure, unless all brake barses are in accurately, predetermined aligned and/or arrangement states, brake bars will prevent the arcuate movement of plunger 42.When reaching required aligned position, plunger 42 just can rotate with respect to cylindrical outer cover 41 arcs.

In addition, rotate required accurate aligned position in order to obtain to make plunger 42 arcs, adopt key spare 50 and 51 with each brake bars axial location required accurately, the pre-position.Key spare 50 and 51 also can provide required leverage, is used to make plunger 42 arcs to pivot.

As long as key spare 50 or 51 is inserted in the holding tank of plunger 42, be combined in the precalculated position that brake bars in the plunger 42 just is aligned in accurate expectation, make plunger 42 to rotate by arcs.This arc rotates and makes and be formed on upright projection 45 on plunger 42 end faces 44 with plunger 42 arcuate movement, thereby makes 46 transverse movements of spring biasing arm spare, will link up with 22 and discharge from its latched position, and make that linking up with 22 can rise to its unlocked position automatically.

At this on the one hand, key spare 50 and 51 is operation by this way all, thereby makes hook 22 releases, opens padlock 20.Yet, as will be described in detail, adopt the master key 50 also can trigger indicator assembly 53, thereby discharge attention device 54, and make it be locked in the viewing position of its rising.

To Fig. 7,, can understand the structure and the operation of indicator assemblies 53 best with reference to figure 3 in conjunction with following detailed description.In preferred embodiment of the present utility model, padlock 20 has indicator assemblies 53, and this indicator assemblies 53 comprises the attention device 54 that is installed on the axle collar 55, and this axle collar 55 is installed on the bolster 56.Remain on the indicator base portion 57 to these parts carry.As clear illustrating among the figure, indicator base portion 57 has the bottom surface 58 that forms groove or arc, curved shape.

For the required triggering to indicator assemblies 53 is provided, padlock 20 also includes the control member 60 between the end face 44 that is installed in indicator base portion 57 and plunger 42.In preferred structure, control member 60 has end face 61, and this end face 61 comprises groove or arc, curved shape, and its groove/arcuate shape with the bottom surface 58 of indicator base portion 57 is nested, be bonded with each other ordinatedly.In addition, control member 60 also is combined with two plates or wall spare 62,63, they extend from the bottom surface of control member 60 and be positioned to mutually side by side, separate, parallel, the relation faced.In preferred structure, wall spare 62 and 63 is mounted to the end face 44 of contact plunger 42, and wall spare 62 and 63 is positioned to directly be close to or ride the outlet slot 65 of plunger 42.

By adopting this structure, as described in detail above, can make plunger 42 arcs rotate with user's key 51, thereby separate locking and hanging hook 22.Yet as long as adopt master key 50 (it is longer than the length of user key 51 that it is configured to entire length), the far-end of master key 50 is outstanding from the groove 65 of plunger 42, enters between plate 62 and 63.Like this, as long as master key 50 is inserted in the plunger 42, separate locking and hanging hook 22 thereby plunger 42 can both rotate, simultaneously since the far-end of master key 50 in plunger 42 arcuate movement and this far-end with the driving of plate 62 and 63 in conjunction with also making control member 60 and plunger 42 rotate simultaneously.

Like this, as long as control member 60 is owing to the motion of master key 50 is rotated, the groove end face 61 of control member 60 just therewith rotates, thereby makes the end face 61 and the groove floor 58 of indicator base portion 57 interact.Because the bottom surface 58 and the inclination of the complementation of the end face 61 of control member 60, the acclive joint of indicator base portion 57, the arcuate movement of control member 60 makes indicator base portion 57 move vertically upward.This motion that makes progress forces attention device 54 to come out from the storage area 66 of shell 21, makes easily to see attention device 54.

In order to ensure the required motion that can obtain indicator assemblies 53 in response to the arcuate movement of master key 50, indicator assemblies 53 also is combined with biasing spring 67 (as shown in figure 13), this biasing spring 67 is installed around bolster 56, and applies downward biasing force to indicator base portion 57 constantly.Like this, indicator base portion 57 just keeps and the contacting of control member 60, thereby has guaranteed that the pivoting action of control member 60 will upwards promote the bottom surface 58 of indicator base portion 57, thereby makes attention device 54 rise to position desired, that see easily.

For such structure is provided, promptly remove master key 50 from padlock 20 and can not make attention device 54 turn back to the storage area 66 (its return the owner that storage area will make padlock 22 can not know immediately opened padlock 20 with master key 50), padlock 20 includes indicator locked component 70.In preferred structure, locked component 70 has support base 71 and from base portion 71 outward extending arms 72.Arm 72 has the lock hook 73 that is installed in its far-end.The last element that is attached in the locked component 70 is a spring 74, and it is installed on the lateral margin of arm 72, and arm 72 arcs are biased into desired locations.

By adopting this structure, the lock hook 73 of arm 72 keeps being bonded on around the axle collar 55 of indicator assemblies 53 usually.Yet as long as trigger indicator 53, attention device 54 just moves upward to this position of seeing easily, and the axle collar 55 moves upward, and bolster 56 is aimed at the lock hook 73 of arm 72.Because spring 74 is constantly towards bolster 56 biasing arms 72, so lock hook 73 engages bolster 56 effectively with arm 72, thereby no matter the position of control member 60 how, all is locked in attention device 54 visible location of rising.

Like this, even after master key 50 is removed from padlock 20, attention device 54 also continues to remain on the visible location of rising.As a result, the user is opened with master key 50 by the Security Officer with regard to learning padlock 20 immediately.

In another feature of the present utility model, the Movement Design that the visible location that attention device 54 rises from it turns back to its retracted position in the shell 21 of padlock 20 becomes to need to use the key that resets that separately, independently only offers the user.Like this, use the Security Officer of master key 50 not opened padlock 20 and attention device 54 is resetted with master key with regard to having guaranteed in order to prevent that the user from learning.

Figure 10 illustrates an embodiment of the key 80 that resets, and Figure 11 shows the embodiment of replacement key combined 81, it is combined in the user's key and the set of keys that resets in the independent product.Can know from Figure 10 and Figure 11 and to see that the part that resets of reset key 80 and key 81 all comprises particular structure, thereby these particular structure are to be complementary with locked component 70 that attention device 54 is resetted is necessary.Particularly, key 80 and 81 all has the finger rod member 82 and 83 that extends from its terminal, and refers to that rod member and accommodation hole in the support base 71 that is formed on locked component 70 mate mutually and engage.With reference to Figure 12 and Figure 13, can understand reset operation best in conjunction with following detailed description.

Padlock 20 residing exemplary position after employing master key 50 is separated locking and hanging hook 22 has been shown among Figure 12.In this position, as seen attention device 54 rises and, and the lock hook 73 of arm 72 engages with bolster 56, and butt keeps in touch under the axle collar 55.As a result, attention device 54 can not move downward, and turns back to its initial position.As shown in figure 12, the bottom surface 58 of indicator base portion 57 separates with the end face 61 of control member 60.In this position, can be clear that the groove that these are surperficial or the feature of curved profile.

The first step that attention device 54 is resetted is to be inserted in the path 32 of shell 21 by 33 counterparts with key 80 or key 81 that enter the mouth.After inserting fully, the finger rod member 82 and 83 of the key 80/81 that resets becomes in the mating holes that is bonded in the end face that is formed at support base 71.As long as insert fully, the key 80/81 that resets pivots with regard to arc, make support base 71 therewith arc pivot.

When support base 71 pivoted owing to the motion of key 80/81, the lock hook 73 of arm 72 broke away from the bolster 56 and the axle collars 55, thereby discharges attention device 54 effectively, and makes attention device 54 move downward its initial position.This downward motion causes by spring 67, and the user pushes attention device 54 downwards and also helps this downward motion.

In case attention device 54 turns back to its initial position, just remove the key 80/81 that resets, and biasing spring 74 makes arm 72 turn back to its initial position, locking an ancient unit of weight 73 engages with the axle collar 55.After key 80/81 was removed in case reset, padlock 20 just can be reused by being fixed on any desired product.

Describe in detail as described above, obviously, padlock 20 provides a kind of key operated structure, it can make the user that padlock 20 is fixed on any desired product, after having guaranteed that simultaneously padlock 20 is at any time opened with master key by customs or Security Officer, padlock 20 will provide clear and definite indication to the user.Like this, the user will learn that padlock 20 lays any damage that may exist in thereon the luggage case or the potential cause of lost objects.Clearly, the utility model provides a kind of key operated pad lock structure, and it has overcome the nearly all difficulty and the shortcoming of prior art.

In addition, as will be described in greater detail, the above-mentioned integral part that provides embodiment caution, key operated pad lock structure also can be embodied as padlock with twin-lock fixed system.Usually, fully integrated twin-lock is decided pad lock structure and is included cipher control part and key control section, and these two all are installed in the shell integratedly.As can seeing easily from Figure 16, described above and be integrated into easily in the shell that also is combined with the cipher control lock part in the precision architecture shown in Fig. 1 to Figure 15, wherein a place is the keyhole that resets.In this embodiment, hook is J-shaped, described cipher control lock part comprises a plurality of rotating code-discs, these code-discs are installed on the long column of J-shaped hook, and be mated, thereby make when described hook each in described code-disc all places the precalculated position axially-movable takes place, and be not that all code-discs stop described hook axially-movable when all being positioned at their precalculated position.

Like this, realized that by adopting this improvement structure fully integrated, twin-lock decides padlock, whenever what it can be in the key operated part of having used padlock with master key provides indication to the customer.Like this, the customer can adopt the padlock that can be opened by the password that user's key or user are provided with, and by utilizing the key operated part of this padlock, can also whenever provide effective caution to the customer what open this padlock with master key.As mentioned above, master key is held by the Security Officer usually, to open luggage case etc. for the purpose of checking.

Replacement preferred embodiment of the present utility model has been shown in Figure 17 to Figure 21.With reference to these accompanying drawings and can understand the structure and the operation of this replacement preferred embodiment best in conjunction with the following detailed description.In addition, purpose for convenience, the same parts that in Figure 17 to Figure 21, adopts identical Reference numeral to represent padlock 20 in this embodiment to be had.Like this, the similitude between these two embodiment is just apparent.And, for fear of in this embodiment of the present utility model open, duplicating, just no longer provide detailed description to the structure of same parts and operation (above be described in greater detail), by reference foregoing detailed description is incorporated into this.

In the structure of this embodiment of the present utility model, the J-shaped hook 22 that key operated padlock 20 includes shell 21 and cooperates with shell 21.Hook 22 has long column 23 and short column 24.In the preferred structure of present embodiment, the long column 23 of hook 22 has the notched region 25 that forms along its length, and at this notched region place, the diameter of post 23 is much smaller than the diameter of post 23 other positions.

In order to control hook 22 motion, the padlock 20 of present embodiment includes lockplate 100, and this lockplate is installed in the shell 21, and is positioned to be approximately perpendicular to the long column 23 of hook 22 and lengthwise movement.In addition, lockplate 100 has the curved cuts zone 101 that is used to engage, and this zone constitutes and is used for engaging with notched region 25 couplings of hook 22 post 23.

As clear illustrating in the accompanying drawing 17,18, when incision tract 101 engages with the notched region 25 of hook 22, just will link up with 22 and remain on its latched position, and engage fully with shell 21.The smaller diameter portion of incision tract 101 vertical surrounding notched region 25, lockplate 100 contacted with the dividing than large-diameter portion of post 23 of hook 22 simultaneously.Like this, when hook 22 during in this position, although spring part 37 effects have biasing force, hook 22 can not axially motion in shell 21.And, because adopt notched region 25 and engaging that the incision tract 101 of lockplate 100 cooperatively interacts in this embodiment, so the axial length of the overall axial length of notched region 25 notched region 25 in the foregoing description.

In order to control the distance of hook 22 post 23, lock washer 102 is installed near the terminal of long column 23 of hook 22 next-door neighbour's spring part 37 with respect to the axially-movable of shell 21.Lockplate 100 cooperates with spring part 103, is used for bias voltage lockplate 100 constantly, and its post 23 with hook 22 is engaged.As a result, the incision tract 101 of lockplate 100 is maintained in notched region 25 fluid-tight engagement with post 23 usually, up to reaction force acts as described below to lockplate 100.

When reaction force makes lockplate 100 lengthwise movements, incision tract 101 is broken away from and the engaging of notched region 25, hook 22 from the engaging of lockplate 100 discharge, thereby make hook 22 move to the position of itself and shell disengaging.Although the lengthwise movement of lockplate 100 makes incision tract 101 break away from and the engaging of notched region 25, incision tract 101 still keeps aiming at the external surface of linking up with 22 post 23.

As a result, along with post 23 because the power of spring part 37 and in shell 21, moving upward, lock washer 102 just with the surface engagement of lockplate 100, thereby limit linking up with 22 axially-movable when being in its release or releasing structure linking up with 22.Yet when hook 22 moved to its shell disengaging configuration, the short column 24 of hook 22 was removed from the joint in the inlet 33 of shell 21, thereby padlock 20 is removed from its fixing special article.

Shown in above-mentioned embodiment, the key operated padlock 20 of present embodiment also includes the housing region that is formed in the shell 21, and the size of this housing region forms to be held and firm maintenance cylindrical outer cover 41.In addition, plunger 42 can be incorporated into this with its main points by reference by mode rotational motion in cylindrical outer cover 41 of above detailed description.

As mentioned above, in the present embodiment, plunger 42 can rotational motion cylindrical outer cover 41 in response to cooperate key spare to be inserted into holding tank 65 (it is formed in the plunger 42, and extends to end face 44 from its bottom surface) always.The end face 44 of plunger 42 is combined with upright projection 45, and it is fixedly mounted on the surface 44 and from this surface and extends upward.Yet in the present embodiment, upright projection 45 constitutes the controlled motion of spring bias voltage lockplate 100.
