Description
Technical field
The present invention relates to the technical field about lock, particularly padlock.
Therefore, the present invention relates to a kind of innovative padlock, its simple in construction, it is thus able to assemble practically, and the most important thing is that this padlock carries out realizing in the way of electroplating tinting technique can stand on its outer surface, on the whole the risk of product abandonment and the structural failure of tripping mechanism is preferably minimized.
Background technology
It is known already for closing the padlock of sack, chest, cupboard etc. Traditional blocking mechanism includes metal lock bridge (arc locks nose), and this lock bridge can move between open and closed positions relative to shell body in combination.
Known technology exists various types of blocking mechanism. Such as in patent US1154078, describing one of them, this patent describing by lock bridge 2 being fixed to the padlock that its shell body 1 is formed. This lock bridge is inverted U-shaped, and one end combines to housing, and the second end is by being controlled to the maintenance system of off-position also in relation with to housing. So, spring 3 tends to lock bridge is pushed into lifting position, thus when maintenance system is controlled in off-position, being promoted by lock bridge, thus discharging its end. This maintenance system is made up of the toothed elements 4 engaged with the otch obtained in lock bridge end. By restricting device (constraint) 6, toothed elements 4 and lock bridge are maintained at locked position of coupler, are connected to the restoring force of the spring 5 of toothed elements 4 with antagonism, and spring and toothed elements 4 are all located in shell body 1 in the given crosswise passage obtained. By rotating lock cylinder 7 with key, it is possible to system being unlocked, lock cylinder 7 guides restriction device 6 to rotate, and restriction device is discharged from toothed elements 4. Toothed elements 4 moves to retracted position by its back-moving spring 5, and discharges lock bridge. By being inserted laterally into the many rotations hindering lock cylinder 7 to the multiple paxillas intercepting lock cylinder 7 itself in housing. Lock cylinder is provided with lock core, therefore, it is possible to rotated by specific key, when key shapes in the correct way and is inserted in lock core, the plurality of small plunger is pushed in its horizontal storage channels by this key, thus discharging lock cylinder itself.
In technology, a lot of other similar schemes are the same as known, the program contemplates the tripping system of lock bridge on the whole, this tripping system is made up of the multiple parts left in shell body 1 by multiple cross-drilled holes, and the plurality of cross-drilled hole arrives internal from the outside of housing and coordinate with the traditional lock cylinder inserted for key. Such as, in the existing situation relevant to US Patent No. 1154078, except the hole inserted for lock cylinder 7 and lock bridge, there is also the hole inserted for toothed elements 4, spring 5 and restriction device 6. Contemplate more hole, for inserting the multiple small plungers 12 laterally intercepting lock cylinder. This some holes has close tolerance, and requires the insertion for the mechanical microcomponent that must insert with high accuracy. In a word, there is the close tolerance in assembling and assemble complexity.
These contents are it is clear that in known technology, so-formed pad lock structure is complicated, and especially assembles complexity. And, except needing to be arranged to deposit the hole of lock bridge and lock cylinder, in addition it is also necessary to various cross-drilled hole is set to insert lock bridge and to be used for fixing the parts that the system of lock cylinder and lock bridge is threaded off. Accordingly, it would be desirable to repeatedly realize shell body with multiple parts.
Additionally, when being predefined for the padlock for fashion product production, this traditional mechanism is totally insufficient to stand follow-up required processing technique already. Particularly, when the padlock of name your make, it is necessary to color is processed, and it is realized by electroplating technology, to be coated with padlock by precious materials (such as gold). Obviously, in this case, aesthetic effect it is critical that, meanwhile, minimum defect all will cause the discarded of product, it is contemplated that the valuable property of the material coated by described padlock, necessarily bring huge economic loss. Unfortunately, it has been shown that the plating coating processes of all padlocks has very high discarded rate in known technology, even greater than the 50% of finished product. This is owing to there is multiple receiving hole for pin and small plunger on shell body, and this some holes has the mechanical tolerance of precision, and as described in the embodiment of US1154078, this some holes is monolithically fabricated the Guan Bi or tripping system that coordinate with lock cylinder and/or lock bridge. Such as, in Fig. 1 part in US1154078, what highlight is not only the cross-drilled hole obtained on housing, also has for for the more hole inserted pin in place to lock cylinder and lock bridge locking, thus hindering these elements to leave position after assembling. Say this layer of meaning, can not be expected to before assembling discrete component (namely only to shell body and lock bridge) is electroplated, this is because described hole will be blocked at least partly, and simultaneously taking account of accurate tolerance, this is by infeasible for the follow-up assembling causing pin. Alternately, common practice predict only when padlock assembles thus the porose parts being all destined to deposit block after padlock could be electroplated. But, in this case, coat also can penetrate in the hole of shell body by minimally, and the risk of deformation (such as crack or depression) occur in this internal gear that there is blocking close tolerance or coat, and this will cause the discarded of product. And, when needs are realized housing by multiple parts, it is contemplated that the complexity of internal part, the result of outside plating is still likely to result in the discarded of product.
What other were similar substitutes constructive scheme is known, although it has made partial contribution to solving a part of described technical problem, but still cannot exempt further problem.
Such as, the scheme of German patent DE 525897 is known and disclosed.
Which describe the padlock that housing realizes with single-piece. To the extent that, plating will not be subject to connecting line impact (when housing by the multiple parts that can be combined to realize time can there is described connecting line). But, the assembling of the dropout of the lock bridge proposed in DE525897 is especially complex, because it contemplates two parts (parts (e) and parts (d)), both parts is connected to each other, and one of them is positioned at another inside, and is fitted to each other.
Particularly, contemplating lock cylinder (d), lock cylinder (d) is can be inserted in the way of rotating in the cylindricality seat obtained in second component (e), and this second component (e) is inserted into again in the seat obtained in housing. Being constructed to of this second component forms undercutting, and this undercutting stops this second component to rotate relative to housing (this second component be assembled in this housing in). Wherein there is the interconnection intercepting the respective transversal passage obtained in lock cylinder, wherein it is inserted with known small plunger and spring, when wrong plug key, these small plungers and spring stop lock cylinder (d) to rotate relative to described second component (e), because these small plungers are formed between the passage and the passage of second component of lock cylinder in this case.
But, this system has following inconvenience: it needs lock cylinder (d) to be combined to second component (e), stop it mutually to translate but the fixing device that allows lock cylinder to rotate. This is obtained by complicated processing, and it contemplates and realizes groove (s) in lock cylinder by the screwed hole inserted for flat head screw, and said two parts are combined by this flat head screw, and its end terminates in described groove (s). So, prevent the relative translation between lock cylinder and second component, but on the other hand, owing to the end of flat head screw is moved to groove (s) when making lock cylinder rotate, therefore do not hinder lock cylinder rotating against relative to its Storage tray.
Obviously, such system is complicated, because it contemplates two different parts, one of them element coaxial is assembled into another inside and is fitted to each other, and entirety needs to use traditional little obstruction plunger (blockingpiston). In addition, it is desirable to realize imitating the receiving hole of the shape of second component in the housing, as depicted, there is undercutting in this second component. To the extent that, such hole is not easily accomplished, because not being circular. Finally, the system that this assembly is fixed to housing being obtained by cross-drilled hole, this cross-drilled hole, from hull outside, intercepts the second component corresponded exactly to this hole, and flat head screw inserts this hole so that second component and lock cylinder are bonded to each other. So, the single flat head screw of accurate sections corresponds to all of maintenance function. But, this scheme on housing with cross-drilled hole obviously hinders electroplated housing before or after all parts assemble, because this cross-drilled hole will necessarily be blocked, hindered insertion or the dismounting of flat head screw.
It is known that other scheme, but from the angle of the realization of these padlocks, it does not aid significantly in simplification to be easily assembled to and to electroplate.
Such as, the scheme recorded in US220637 does not contribute to the solution of technical problem, because which describing the housing (therefore can not electroplate) formed with two half-unit, have employed extremely similar to the record in document DE525897 (at least exist small plunger in) the solution lock set of lock bridge.
Describing the assembly for unlocking lock bridge in GB840994, it contemplates the multiple concentric rings in the cylindricality seat being sequentially stacked on housing, the structure ring ring phase transformation of centre bore, thus forming the insertion combination of correct key.
Multiple concentric ring is used to cause that device is difficult to, poor reliability, and assemble complexity. And, there is the cross-drilled hole for assembling all parts, this will hinder the accurate plating of housing.
US1683985 employs tradition lock cylinder, but, when using correct key, not by use small plunger but by a kind of simpler mode (namely, mode by toothed elements is ejected) by the rotation of locking lock cylinder, wherein toothed elements is anchored on the circular wall of the seat inserted for lock cylinder in the housing. But, the whole locking assembly used in this case combines in the housing by covering, described lid is applied to above housing, and the pin that utilization enters laterally enclosure interior from hull outside is fixed on original position, thus also defining cross-drilled hole in the housing, if acquisition satisfactory result can be hindered when in this case housing being implemented plating.
Summary of the invention
Therefore, it is an object of the invention to provide a kind of innovative padlock at least solving the inconvenience of part described technology.
Particularly, need to provide a kind of padlock of simple in construction and practicality on assembling, and especially, this padlock can stand electroplating process for surface, discarded it is preferably minimized what be correlated with by the surface defect of the coating material internal mechanical fault of construction that causes of infiltration and/or coating itself.
Therefore, it is an object of the invention to provide a kind of padlock, the tripping system (particularly lock cylinder) of its lock bridge, simple in construction and efficiently, it is not necessary to realize from outside being combined in housing by this system with close tolerance and/or contribute to the cross-drilled hole of its blocks rotation/unblock and just this system can be inserted in housing.

Detailed description of the invention
With reference to Fig. 1, the padlock 100 according to the present invention is described.
Padlock includes such as by the metal lock bridge 102 such as steel, ferrum. Lock bridge has arc or an inverted U-shaped shape, and the sections of preferred its one end is more than the relative other end. Particularly, illustrated by following, the one end do not ejected from padlock housing is longer than the relative other end, and this other end coordinates with the maintenance system 106 being used for being latched in lock bridge closed position on the contrary.
Therefore, highlighting in Fig. 1, lock bridge can be combined with shell body 103 in closed position. Particularly, as detailed below, shell body 103 internal storage has and lock bridge is latched in closed position (shown in Fig. 1) or is unlocked thus the mechanism that is in the open position.
Obviously, shell body 103 can be any shape and any material (such as steel, ferrum etc.).
In shell body, design has seat or the storeroom of passage 200 shape, is used for inserting blocking device 105, and it includes the lock cylinder 105 that the holding means 106 with top matches.
For this, for the sake of clarity, Fig. 6 is highlighted the sectional view of single shell body to highlight the described passage 200 depositing lock cylinder 105. Another passage 210 is for depositing one end (the longest end) of lock bridge, and third channel 220 deposits the generally shorter other end of lock bridge. Passage 220 is connected to passage 200 by transverse segment 201, deposits toothed elements 107 in transverse segment 201, illustrated by following, toothed elements 107 belongs to the holding means 106 being arranged in lock cylinder 105 top. Equally, Fig. 6 illustrates the manufacture of cylindrical passageway 200, to be formed and add sipes 200 ' for locking lock cylinder 105 by applying metal retaining ring (technical term is referred to as " snap ring "). At opposite side, passage 200 is formed with the diameter groove 200 less than this passage 200 ", illustrated by following, groove 200 " stop holding means 106 to rotate relative to passage 200, form undercutting. Such as, this groove 200 " can have a cross section of tetragon or triangle, and deposit the complementary end 106 ' of holding means 106, thus being incorporated into making it not rotate.
Shell body 103 is the single block realized with single-piece, wherein, utilizes known particular tool (for the drill bit holed, reamer etc.) to obtain described passage (or seat) from one integral piece.
So, following illustrated, in housing 103, it is absent from joint, this allows shell body 103 is carried out point-device plating, and the risk of free from flaw or breakpoint.
And, illustrated by following equally, the lock cylinder 105 being connected to holding means 106 incorporates except all devices of the opening and closing of the outer control lock bridge of the rotation stopping part of prevention lock cylinder 105 rotation when inserting error key in himself. So, cross-drilled hole as need not have technology as known on housing, it is allowed to before assembly single housing and lock bridge are carried out electroplating operations so that electroplating operations is very accurate.
According to the present invention, following illustrated, padlock design has the holding means 106 matched with the lock cylinder 105 being rotatably inserted into housing. The top of lock cylinder is formed with cam 150, cam 150 coordinates with the holding means 106 of top, so that when leading cam to rotate by the rotation of lock cylinder 105, the profile of cam guide the toothed elements 107 belonging to holding means lock bridge engaged at end thus locking lock bridge position and the position of release lock bridge between move.
This cam-toothed elements system allows easily and rapidly to assemble without extra cross-drilled hole, and the most important thing is in the housing, and this system is practical system reliably.
Additionally, this lock cylinder is integrated with rotation coupling apparatus 180 in himself, the design of this rotation coupling apparatus has can eject from which and thus eject the toothed elements abutted with the wall of the direct passage 200 inserted with this cylindrical device from this cylinder. By inserting a key into the ejection/retraction controlling this toothed elements in the lock core of lock cylinder. The key of mistake makes this toothed elements rest on and the abutted position of passage 200, therefore stops lock cylinder 105 to rotate relative to passage, thus stoping the rotation of cam 150. Cam does not rotate so that keeping the toothed elements abutted with lock bridge not move.
But, the program allows to use the housing 103 of " completely " completely and this plating allowing first to be precisely carried out single housing and lock bridge, then carries out the follow-up assembling of each parts, then obtains the device of perfect operating.
Therefore, in detail, returning to Fig. 1, the holding means 106 coordinated with lock cylinder 105 conceives the toothed elements 107 having the otch 108 obtained with the short end place at lock bridge to engage. To the extent that, one end with otch of lock bridge is slideably inserted in the special modality 220 obtained in the housing, until this end finds described toothed elements 107 and engages with described toothed elements, thus himself is incorporated into locked position of coupler. The other end of lock bridge is correspondingly combined in the passage 210 of shell body 103 in a position-stable manner. Especially, it is allowed to this long end slides certain amount in sliding channel 210, particularly slide and reach to make the amount of the elevated and fully out shell body 103 of the other end. Thus, by not allowing the block piece (130,211) of this long end its sliding channel 210 fully out to hinder the stroke of this long end. Compression spring 111 is inserted in the end of described passage 210, and is calibrated on the direction of improvement of the housing deposited relative to it at lock bridge and applies permanent thrust F. When toothed elements 107 departs from otch 108, lock bridge is promoted by the action of the spring 111 compressed, and makes lock bridge slide into its open position, namely, the one end with otch 108 is in ejected position relative to its sliding channel 220, and long end arrives its block piece place in passage 220.
As shown in Fig. 6 and Fig. 1, this block piece is obtained by the interstitial segment (that is, the sections 210 ' again limited in its decline) widened. So, defining upper and lower Zhi Tai (abutment) 211 (referring to Fig. 1), it stops long end leaving channel 210 and limits the sliding stroke in both direction. For this, the retaining ring 130 that this Zhi Taiyu is placed on described end on the groove 131 (referring also to Fig. 2) obtained matches. This ring (is referred to as western lattice ring) and has certain thickness, so that this ring of one side is blocked and slides from without the end relative to its placement in a groove, this ring is relative with the platform 211 in Fig. 1 on the other hand, thus stoping lock bridge leaving channel under the promotion of spring.
Described ring 130 is such as harmonic wave steel (harmonicsteel) material, and in its feature, except presenting high mechanical resistance, this material especially can keep original-shape at the Kong Zhonghou being compressed into entrance lock cylinder.
So, simple and practical maintenance system is obtained.
Similarly, as visible in Fig. 4 and Fig. 6, lock cylinder 105 has identical maintenance system in its cylindricality seat 200. Particularly, as it has been described above, as shown in Figure 4, snap ring is placed in the groove of lock cylinder, and slides relative to seat 200 by means of with the prevention lock cylinder 105 that coordinates adding sipes 200 ' obtained in seat 200.
Describing the present invention in further detail, we transfer to the structure to holding means 106 and describe.
Such as shown in Figures 2 and 3, holding means 106 design has the cylinder 112 depositing spring 113, and this spring is calibrated on the ejection direction of toothed elements 107 and applies power F1 (referring to Fig. 2). As clearly shown in Figure 3, this cylinder 112 is formed with the inner seat depositing spring 113, and this spring 113 is fixed on one end of described seat, and its other end is fixed on toothed elements 107. Cylinder 112 design has pivot 114, illustrated by following, pivot 114 vertically extends and downwardly directed lock cylinder 105 from the lower substrate of this cylinder itself. Therefore, pivot 114 and cylinder 112 are one.
Toothed elements 107 is slided relative to its seat inserted, as it is shown on figure 3, this opens wide in the side (part that namely pivot 114 therefrom stretches out) of the lower substrate of described cylinder, and is communicated to the seat depositing spring 113. Toothed elements constructs in the way of design has adnexa 107 ', and this adnexa is directed vertically to the lock cylinder 105 of lower section as pivot 114. As it has been described above, deposit the seat of spring and toothed elements from bottom-open, so that this adnexa 107 ' to bottom projection, as pivot 114, and can the most important thing is, this otch coordinated with adnexa 107 ' actually forms the sliding guide of toothed elements.
It is thus possible, for instance as shown in Figure 4, above-mentioned holding means 106 is accurately coordinated with the lock cylinder 105 of lower section by described adnexa 107 ', so that the retraction translation that the Spin Control toothed elements 107 that this lock cylinder 105 is in one direction is in it. Corresponding to the reverse rotation of lock cylinder 105, spring 113 will tend to make toothed elements 107 return to ejected position.
More particularly, Fig. 4 illustrates lock cylinder 105, and this lock cylinder can such as rotate in the counterclockwise direction by the specific key of use. As shown in Figure 5, this lock cylinder 105 is formed with a kind of cam 150 in the end relative with key insertion end, this cam coordinates with the end 107 ' of toothed elements 107, when lock cylinder counter clockwise direction along Fig. 4 rotates, to make toothed elements 107 translate towards the retracted position in the seat of cylinder 112.
In more detail, Fig. 7 illustrates the structure of obtained cam 150, wherein, obtains groove 151 at the top of lock cylinder 105, and the end 107 ' of toothed elements 107 is inserted in this groove and continues with it contact of swiping. Especially, end 107 ' with limit this groove 151 and wall 152 continuous contact guiding toothed elements to translate. So, when guiding lock cylinder 105 to rotate (highlighting in Fig. 5) relative to its cylindricality seat 200 inserted, with under the guiding contacted of cam, toothed elements is forced to retract, thus departing from lock bridge. Under the promotion of the spring 111 of lower section, lock bridge is promoted to open position. The continuous contact of end 107 ' and cam (particularly with the wall 152 effectively forming guide cam) is obtained to the lasting promotion of the ejected position of toothed elements by spring 113.
Torque spring 160 is positioned at below cam, makes lock cylinder 105 return to initial position, so that toothed elements is again at ejected position relative to its sliding seat. This is because torque spring makes lock cylinder 105 rotate in opposite direction relative to previous rotation of opening, cam is therefore made to rotate in mutually opposite directions. Based on context it can be seen that toothed elements is pushed into ejected position and the profile variations of the cam owing to rotating by spring 113, this toothed elements is advanced. The rear portion of toothed elements 107 is formed with chamfering 107 " so that when lock bridge is pressed against in toothed elements, this chamfering produces the force component making toothed elements again be retracted in seat, the power of antagonism spring 113. Once lock bridge has crossed chamfering 107 ", toothed elements is pushed against on otch 108 by spring 113, thus combining to closed position.
Especially, as it is shown in figure 5, cam rotates counterclockwise, the structure of the wall of cam make to produce to act in toothed elements, force toothed elements to be retracted into the force component in it, the power of antagonism spring. So, toothed elements is retracted to its passage, separates with otch 108. In this stage, lock bridge is pushed into raised position by spring 111. When unclamping key, torque spring 160 make lock cylinder rotate to initial position (i.e. position in Fig. 7, but wherein lock bridge lifting, thus do not engage with toothed elements). In the process rotated towards initial position, toothed elements 107 returns to ejected position, because toothed elements 107 is subject to being positioned at the promotion of the spring 113 at its rear portion, and because cam has been rotated to initial position thus allowing toothed elements to eject.
When padlock closed by needs, as it has been described above, to by chamfering 107 " the lock bridge applying pressure that engages with toothed elements 107.
Certainly, lock cylinder is not restrictive for determining the direction clockwise or counterclockwise beating opening/closing, because by applying described concept, it is possible to achieve by the same mechanism carrying out locking/unblock with described contrary rotation.
By being co-axially inserted by torque spring 160 to lock cylinder 105 and being positioned to one end 161 of this spring relative with the pivot 114 of the device 106 belonging to fixing top in Fig. 2, it is accurately obtained the twisting action of described torque spring.
Particularly, for instance as shown in fig. 1, holding means 106 is assembled into relative to its cylindricality seat 200 fixing (namely can not rotate) inserted, and the lock cylinder 105 of lower section can rotate relative to the seat of its assembling. So, it is twisted with the torque spring of lock cylinder 105 (this lock cylinder rotates and coordinates with fixing pivot 114) one according to the rotation of lock cylinder 105 and discharges.
As initial described, by with the groove 200 being positioned at holding means 106 head and adnexa as shown in Figure 1 106 ' coordinates " structure of (Fig. 6) obtains the holding means 106 rotation block piece relative to its seat 200 inserted. This groove 200 " there is specific cross section, such as square sectional, for instance the adnexa 106 ' equally with square sectional is inserted in this groove, owing to being formed with undercutting, thus defines rotation block piece.
So, the end 161 that the one applying of torque spring 160 end 114 to lock cylinder 105 and with the holding means 106 (it is fixing by rotating) of top coordinates makes to form a retrieval system, and this retrieval system makes described lock cylinder 105 return to initial position after lock cylinder rotates.
For this, what Fig. 8, Fig. 8 _ 2, Fig. 9 and Fig. 9 _ 2 described between pivot 114 and the end 161 of spring this is connected.
Such as, Fig. 9 illustrates in lock cylinder that design has all integrally formed top section 105 ' each other, underclad portion 105 " and position the mid portion 105 of described torque spring " ', in top section 105 ', wherein obtain described cam. Fig. 9 _ 2 illustrate these three part, and prominent illustrating defines the seat 169 depositing described spring and axle 170 on described mid portion, and described spring applies around this axle.
It is best illustrated in Fig. 9 _ 2, lock cylinder 105 is obtained by two half-unit, and this two half-unit can be passed through the prominent multiple pins (highlight in Fig. 8 and be shown in which two pins) illustrated in Fig. 8 and is connected to each other and can fix by the resin of bi-component, glue, interference fit. The two half portion is asymmetrical relative to one another, and especially, in one and half less portions, design has axle 170 to be applied thereon by spring, and is formed with seat 169 and the top section 105 ' of spring in second half portion. As shown in the sectional view of Fig. 8 and Fig. 9 _ 2, top section 105 ' there is also formed body 190, this formed body is actually the part of removal, to allow the front of pivot 114 present 169 to be positioned adjacent to part 105 " ' in the end of torque spring.
The net shape allowing to be readily derived described lock cylinder 105 is realized by asymmetric two half-unit.
Therefore, the assembling of lock cylinder 105 is very simple. From Fig. 9 _ 2, torque spring is inserted on pivot 170, and two half-unit is engaged.
Fig. 9 _ 2 and Fig. 8 also show two block pieces 191 that restriction lock cylinder rotates so that block piece is against fixing pivot 114. Especially, the structure of the lock bridge locking from Fig. 8 is illustrated starting at, and as Fig. 8 _ 2 rotate key, is unlocked by lock bridge, it is allowed to lock cylinder 105 rotates, so that being in twisting states with lock cylinder 105 torque spring integrally. Accurately limited by the block piece 191 ' resisted with pivot 114 and open rotation. When unclamping key, lock cylinder returns to the position in Fig. 8 by torque spring, and it rotates another block piece 191 being blocked pivot 114 " restriction.
The structure continuing the present invention describes, and Figure 10 illustrates the block piece being operable to stop lock cylinder 105 to rotate relative to shell body when the key of mistake in.
For this, lock cylinder is conceived porose 180, this hole is equally visible in Fig. 9 _ 2. This hole is through the diameter (being not necessarily radial hole) of lock cylinder, and forms the interconnection inserted for spring 181 and toothed elements 182 in lock cylinder 105.
Section A-A illustrates the cross section of the housing 103 with internal lock cylinder 105, and is highlighted all parts in the passage 180 being present in lock cylinder, i.e. spring 181 and toothed elements 182. The design of this toothed elements has the cross sections 183 with chamfering 184. The spring 181 being positioned at toothed elements 182 rear portion tends to promote this toothed elements from the opposite side in hole 180, thus this toothed elements being pushed against on the inwall of housing towards specific received block 185. When inserting correct key, key enters otch 183, creates power by described chamfering 184 in toothed elements 182, and described toothed elements is pushed into retracted position by the power of this power antagonism spring 181. So, described toothed elements is retracted in passage 180, and departs from the wall of shell body. This is because, this chamfering is configured to have such angle, and when inserting correct key, described angle forms the force component making described toothed elements retract, and this force component becomes " thrust " component. Especially, the seat 185 that toothed elements 182 obtains from somewhere the wall at passage 200 departs from. So, lock cylinder 105 can relative to its cylindricality seat 200 inserted freely accessible for rotation.
The closing pin (closingpin, closing pin, closure pin) holding the spring in position can be substantially predicted from the insertion portion of spring 181.
May be inserted into more toothed elements, and/or its position can be changed.
Therefore, the assembling of described padlock contemplates the following stage:
Starting point such as can be described above the assembling of the two half-unit of lock cylinder 105. Then, " snap ring " is applied in lock cylinder 105. With reference to Fig. 6, and then can holding means 106 be inserted in passage 200, until adnexa 106 ' inserts seat 200 " in. It is inserted into lock cylinder 105, until snap ring is bonded in groove 200 ', with by place for entirety locking. Certainly, in the insertion process of device 106, toothed elements 107 is retracted in its seat and when finding lateral seat 201 in its front after arrival accurate location, it is possible to freely eject. Then, together with the insertion of lock bridge, it is possible to achieve inserted by spring 111 in passage 210, described lock bridge keeps locking in place by its snap ring coordinated with a platform 211.
Fully describe the present invention from structural point above, below we enter the description of its advantage.
As shown in Figure 6, only existing three main vertical passages, these three main vertical passages obtain in the shell body formed with single-piece. Therefore lock bridge is allowed to beat opening/closing and thus allowing the system of the follow-up rotation of lock cylinder 105 to be intactly incorporated in lock cylinder 105 and holding means 106 when using correct key, without being contemplated that by passing completely through shell body and there is the integration system that the cross-drilled hole of close tolerance is applied.
All these mean, it now is possible to main single external part (i.e. lock bridge and shell body) is electroplated, it is to avoid the whole padlock assembled is electroplated. This is because, no longer there is the following risk in known technology: the small size in housing and the tolerance cross-drilled hole coordinated with lock cylinder must be filled with and take out or housing multiple parts joint produce crack. It is true that shell body is currently without cross-drilled hole and pin, what discuss in view of us is moveable lock bridge and rotatable lock cylinder, and all parts being positioned in passage 200,210 and 220 described at present is natural even to be inserted with certain interval with bigger tolerance.
Therefore to the extent that, it is possible to single shell body and lock bridge are electroplated, and this save considerably coating material, and can overall package, determine the correct machine operation of system in a word and with best Surface Finishing.
The another variation of the present invention is described with reference to Figure 11 to Figure 17.
Being that as it may, in this case, torque spring 160 is now located at opposite side, and namely torque spring is wrapped in around lock cylinder 105 near the region of lock core. One end of this spring is fixed to lock cylinder, and one end is fixed to block piece 216, and this block piece is combined in the Storage tray of lock cylinder.
As afore-mentioned, the rotation of lock cylinder 105 makes this spring enter twisting states as follows, and described mode is, when unclamp make key that described lock cylinder rotates time, make lock cylinder return to initial position.
The advantage of the program is to assemble will be significantly simpler. In the first scenario, it is necessary to will be equipped with the whole lock cylinder 105 after holding means and preloaded spring and be inserted in the passage of housing. This preloaded spring tends to make whole assembly rotate, and inserts thus not easily overall so that the undercutting 106 ' being arranged in holding means head is inserted into preset seat.
In this variation, it is possible to the entirety not having spring assembled, then only arrange described spring and ring in end.
Another variation (content having been noted above keeps effective equally) relates to the use of the dual system stoping lock cylinder 105 to rotate when the key of mistake in. Certainly, no matter according to which embodiment in described embodiment, described torque spring is positioned, the program can be used.
Especially, this rotation coupling apparatus is essentially equivalent to described aforementioned rotation coupling apparatus, and simply, in this case, design has each other at a certain distance by two toothed elements 282 placed. So, the assembly that the liberation mechanism by being more difficult to is opened is defined.
In the order of Figure 12 and Figure 13, after inserting correct key, the end 285 of the two toothed elements is shown in retracted position, during wherein said key promotes toothed elements towards the bottom translation of special seat to lock cylinder, so that lock cylinder itself rotates freely. The two toothed elements is pushed in lower position by correct key, departs from the storage channels in housing in this lower position medial end portions 285.
This end is rested on locked position of coupler by the key of mistake.
When extracting key, spring makes the end return of toothed elements engage with cylindrical wall.
Toothed elements 282 has generally L-shaped, and the top end at the minor face of this L-shaped obtains end 285. Spring such as side shown in Figure 12 contacts thus this toothed elements is pushed to the outside of lock cylinder 105 with the minor face of this L-shaped, and opposite side (this cross section is not shown) contacts with lock cylinder.
