Description

The connection structure and the table of table

Connection structure that the present invention relates to show and the table that uses this connection structure particularly construct and use this to be connected the table of constructing with the connection of the fixedly connected portion of connecting pin.

Figure 11 is a kind of the connected mode that adopts at present with the structure that is connected shown in Figure 12.As shown in the figure, long connecting pin 34 is to be connected to use link with short guide 35.Specifically, when the table body connecting portion 30 of table is connected with connection section of watch chain 32, at first the guide 35 of hollow form is put into the set patchhole 31 of table body connecting portion 30, lifting connection section of watch chain 32 then, make that the patchhole 33 of connection section of watch chain 32 is corresponding with the patchhole 31 of table body connecting portion 30, connecting pin 34 inserts in these 3

holes

33,31,33 afterwards.When this insertion process was over, the table body and the watch chain of table just became one structure.

In order to make table in use, connecting pin 34 is unlikely the dropping in the purposes that make of table, tends to establish at the middle part of connecting pin 34 a reduced outer diameter portion 36.When two connecting

portions

30 and 32 interconnected, the external diameter reducing diameter part of connecting pin 34 36 embedded in the set internal diameter reducing diameter part 37 of guide 35, and at this moment, 34 of connecting pins are fixed.

The connection structure of coupling part shown in Figure 13 is the another kind of connected mode that the Japan special permission disclosed spy in the Room opens the prior art described in the flat 08-224114 communique.The bifilar shape connecting portion 42 of table body 40 is provided with the connecting

hole

41,41 of connecting pin 50 insertions that can allow a kind of two ends establish lug boss 53,53.In the connection section of watch chain 45, also establish a through hole 46 that traverses connection section of watch chain 45, the cross section in this hole 46 is the silk cocoon shape, and the packing ring 47 of a cross sectional shape identical with through hole 46 is put into this through hole 46.Then, in the packing ring 47 that the silkworm chrysalis shape collar 60 that is provided with the formed neck 63 of connecting place of big footpath hollow bulb 61, path hollow bulb 62 and two

hollow bulbs

61 and 62 is inserted in the through hole 46.

The internal diameter size of the big footpath hollow bulb 61 of the collar 60 can be inserted smoothly with the lug boss 52 of connecting pin 50 and be as the criterion, the internal diameter size of path hollow bulb 62 is big or small close with the footpath of the roundlet perimembranous 51 of connecting pin 50, the diameter that should be slightly less than roundlet perimembranous 51 in a narrow margin of neck 63.Then, the connection section of watch chain 45 that inserts the packing ring 47 and the collar 60 is inserted between the table

body connecting portion

42 and 42 of double socket shape, make that the big footpath hollow bulb 61 of the collar 60 is corresponding with the connecting hole 41 of table body connecting portion 42, afterwards connecting pin 50 is inserted in the big footpath hollow bulb 61 of the connecting hole 41 and the collar 60.Then, will show body connecting portion 42 and connection section of watch chain 45 draws in the opposite direction, 51 of the roundlet perimembranous of connecting pin 50 can be shifted to the path hollow bulb 62 from big footpath hollow bulb 61 by neck 63.At this moment, two connecting portions 42 are finished with 45 the operation that is connected.

Wherein, Figure 11 and shown in Figure 12 being connected in the structure, though link has only 35 two kinds of connecting pin 34 and guidees, have that syndeton is simple, the advantage of the handling ease of link, but, in order to allow connecting pin 34 insert in the guide 35, the reducing diameter part 37 necessary elastic dilatations of guide 35 need very big strength.Usually cause the assembling operation difficulty thus, the time of cost increases.Also have, surpass 5 kilograms for elongated connecting pin 34 used vertical forces, connecting pin 34 will flexural deformation, and table body that thus can his-and-hers watches and the surface of watch chain produce scar, thus the outward appearance and the quality of influence table.So, in order to solve the outward appearance scar problem of table, also to use special instrument, this has increased manufacturing cost again, and can not solve the flexible problem on deformation of connecting pin 34.

In order to solve the problem on deformation of connecting pin 34, unique method is to make the bed knife of guide 35 weaken (internal diameter of the reducing diameter part 37 of guide 35 increases), tends to the appearance table so in use, and connecting pin 34 is dropping unconsciously.Show in use in order to make that connecting pin 34 can not come off, the bed knife of guide 35 must be strengthened, and when the length of watch chain need be adjusted, withdrawing from of connecting pin 34 was then very difficult.Because the reducing diameter part 37 of guide 35 is plastic yield, when the external diameter of connecting pin 34 during greater than the internal diameter of the reducing diameter part 37 of guide 35, the insertion meeting of latch 34 is very difficult, and used strength is also unstable.

In the connection shown in Figure 13 structure, in the cargo handling process of table body 40 and watch chain 45, do not need very big strength, as long as relatively move table body 40 and watch chain 45 are just passable.But this connection structural member is a lot, can cause manufacturing cost to rise like this, and the possibility of losing link during loading and unloading also can take place.In addition, table body 40 and watch chain 45 must set in advance the space that two sides will move in cargo handling process, and this tends to influence table and watch chain design in appearance.

In addition, xsect is that the job operation of through hole 46 of silkworm chrysalis shape is very complicated, the connecting portion 45 of watch chain must be divided into two parts in the process up and down and process the hole respectively half, then will be up and down two ones engage fixing.Thereby can making the production process of parts increase, this job operation causes that production efficiency reduces, makes the cost of table to raise.

The objective of the invention is to, solve above-mentioned various unfavorable factors, provide that a kind of link is few, the processing of parts is with to be connected operation simple, cost is low, loading and unloading easily and fundamentally solution show the connection structure of table of the problem that connecting pin in use drops and the table that uses this connections to construct.

The technical scheme of the connection structure of table of the present invention is, be arranged in the set connection in table body both sides with showing the body connecting portion, be arranged at the connecting hole of the lateral direction penetrating that connection section of watch chain on the watch chain and this two connecting portion be provided with respectively and make the table body of table and the connecting pin that watch chain connects as one by each connecting hole, in said two connecting holes, have at least a side to put into turn, and the fixedly connected pin of effect of the internal diameter by this turn, make two connecting portions and becoming one, wherein the one or both ends of connecting pin are provided with the rotating part that this connecting pin is rotated.

This connection structure can make number of components and parts reduce, and the operation of assembling operation is oversimplified.For turn, one processes advantage easily, and cost is reduced; The 2nd, effectively utilized the characteristic of spring, fixing and when withdrawing from connecting pin, do not need very big strength to realize.In the time of in connecting pin inserts turn, each circle of turn all wraps in the surface of connecting pin tightly, the spring of each circle promptly is the bed knife of connecting pin to the friction force of connecting pin, and the possibility that connecting pin oneself drops under no external force effect so just can not take place.

In addition, because connecting pin is to insert while rotating or take out along the direction identical with the spooling direction of turn, when field-strip, also can take out connecting pin simply effortlessly, and each connector of his-and-hers watches is difficult for causing scar, and connecting pin can be because of removal force flexural deformation yet.

Another technical scheme of the connection structure of table of the present invention is, be positioned at any two adjacent connectors on the continuous watch chain of table body by the connecting pin connection, wherein an end of each connector is established connecting portion, the other end is established the portion that is connected that connecting portion therewith is connected, and horizontal connecting hole is set respectively in two connecting portions, it is characterized in that having at least a side to put into turn in said two connecting holes, the fixedly connected pin of effect of the internal diameter by this turn, make the connecting portion and the portion of being connected on the watch chain become one, wherein the one or both ends of connecting pin are provided with the rotating part that this connecting pin is rotated.

This connection structure one can make number of components and parts reduce, and the operation of assembling operation is oversimplified, and work efficiency improves greatly, thereby realizes that cost has alleviated the weight of watch chain when reducing; Number of components and parts reduces the outward appearance and the design that also can make watch chain and reaches the own aesthetic of being wanted.Two can effectively utilize the characteristic of spring, and fixedly connected simply pin makes its bed knife strengthen.

In addition, above-mentioned connecting pin can also be that small end inserts the central portion of the connecting hole of above-mentioned correspondence relatively, two screw-like connecting pins of rotation section are established in the rear end of outside portion.Like this, just the outside portion of these two screw-like connecting pins can be designed to end, make design diversified greater than connecting hole.

Screw thread is established on surface at said connecting pin, can be more convenient for loading and unloading connecting pin so that the surface of contact of the internal diameter of the surface of connecting pin and turn reduces.

Another technical scheme of the connection structure of table of the present invention is, be positioned at the set connection in table body both sides with showing the body connecting portion, be arranged at the connecting hole of the lateral direction penetrating that is provided with respectively in connection section of watch chain on the watch chain and this two connecting portion and make the table body of table and the connecting pin that watch chain connects as one by each connecting hole, it is characterized in that having at least a side to put into turn in said two connecting holes, above-mentioned connecting hole is corresponding be a straight line in, insert two screw-like connecting pins respectively from both sides, and the effect of the internal diameter by this turn fixes two screw-like connecting pins, makes two connecting portions become one.

This connection structure can make number of components and parts reduce, and the operation of assembling operation has alleviated the weight of the whole connection structure of table when oversimplifying.For turn, one processes advantage easily, and cost is reduced; The 2nd, effectively utilized the characteristic of spring, fixing and when withdrawing from connecting pin, do not need very big strength to realize.In the time of in connecting pin inserts turn, each circle of turn all wraps in the surface of connecting pin tightly, the spring of each circle promptly is the bed knife of connecting pin to the friction force of connecting pin, and the possibility that connecting pin oneself drops under no external force effect so just can not take place.

In addition, because connecting pin is to insert while rotating or take out along the direction identical with the spooling direction of turn, when field-strip, also can take out connecting pin simply effortlessly, and each connector of his-and-hers watches is difficult for causing scar, and connecting pin can be because of removal force flexural deformation yet.Because of having used two screw-like connecting pins, just the outside portion of these two screw-like connecting pins can be designed to end greater than connecting hole, make design diversified.

Because the both sides of above-mentioned two screw-like connecting pins are established the rotating part that this connecting pin is rotated respectively, can be so that connecting pin along inserting while rotating or take out with the spooling direction of turn, be more prone to feasible.

Another technical scheme of the connection structure of table of the present invention is, it comprises any two connectors that are connected in the watch chain that links to each other with the table body, wherein a side is a connecting portion, the be connected portion of the opposing party for being connected with connecting portion, connecting portion be connected the connecting hole that is respectively equipped with lateral direction penetrating in the portion, have at least a side to put into turn in the said connecting hole, insert two screw-like connecting pins respectively from both sides when being a straight line in that above-mentioned connecting hole is corresponding, and the fixedly connected pin of effect of the internal diameter by this turn, make two connecting portions become one, the rotating part that this connecting pin is rotated is established in the both sides of wherein above-mentioned two screw-like connecting pins.

This connection structure one can make number of components and parts reduce, and the operation of assembling operation is oversimplified, and work efficiency improves greatly, thereby realizes that cost reduces; Number of components and parts reduces the outward appearance and the design that also can make watch chain and reaches the own aesthetic of being wanted.Two can effectively utilize the characteristic of spring, fixing simply and withdraw from connecting pin, more need not worry coming off of connecting pin.In addition,, just the outside portion of these two screw-like connecting pins can be designed to end, make design diversified greater than connecting hole owing to used two screw-like connecting pins.

The external diameter of establishing screw thread, outer end rotating part in the periphery of the small end of said two screw-like connecting pins is big and cover the aperture of connecting hole than the connecting hole of lateral direction penetrating.Such structure can make the head in connecting pin outside when being fixed by turn hide the aperture of connecting hole, makes design diversified.

In said interconnective each two connecting portion, one side establishes the bifilar shape connecting portion of both sides projection, the opposing party then is made as intermediate projections and can stretches into the convex connecting portion of the trench portion of above-mentioned bifilar shape connecting portion, each lug boss that is connected is established the connecting hole of lateral direction penetrating respectively, put into turn in the set connecting hole of convex connecting portion, insert with two screw-like connecting pins and connect two connectors in each connecting hole.

This syndeton can be avoided must setting in advance the space that two connecting portions will move in the aforesaid prior art, and the freedom of appearance design of his-and-hers watches further raises.The setting of other three connecting holes also only is slightly larger than the external diameter of connecting pin, so no matter the his-and-hers watches body still is the connecting portion of watch chain, all can and make to thin skilful light direction design.In addition, because turn is put in the centre of three connecting holes, can guarantee that the position of turn is stable.

The minor diameter part of one or more internal diameters less than the internal diameter of other parts is set on the said turn, the reducing diameter part of one or more external diameters less than the external diameter of other parts is set on the said connecting pin, when connecting pin inserts turn, above-mentioned reducing diameter part embeds in the minor diameter part, in order to the position of fixedly connected pin.

This structure of turn can be so that connecting pin be when passing through minor diameter part, and the minor diameter part dilatating and deformable is even the rear portion of the connecting pin of extruding gently also can be inserted in the internal diameter of turn easily.When the reducing diameter part of minor diameter part and connecting pin is chimeric,, can confirm performance simply, to avoid the generation of defective products because the effect of the elastic restoring force of minor diameter part can be sent chimeric sound and sensation.In addition, because the reducing diameter part of the minor diameter part of turn and connecting pin is chimeric mutually, the bed knife of connecting pin further strengthens.

The setting of the internal diameter of said turn is slightly less than the external diameter of connecting pin, by the fixing said connecting pin of the friction force that elastic restoring force produced of turn.If when not establishing minor diameter part on the turn, the internal diameter of whole spring is smaller than the external diameter of connecting pin to be good, as turn, when the connecting pin also thicker than own internal diameter inserts, the whole dilatating and deformable of turn, because the effect of elastic restoring force makes the friction force that acts on the connecting pin surface to increase, promptly the bed knife of connecting pin increases, and has avoided connecting pin coming off in the use of table.

At the set rotating part in the both sides of said connecting pin is cross or the groove of yi word pattern.Such structure can make connecting pin utilize the characteristic of turn to insert or take out from the internal diameter of turn while rotating with less power.

The technical scheme of table of the present invention is, it comprises and is arranged in the set connection in table body both sides with showing the body connecting portion, be arranged at the connecting hole of the lateral direction penetrating that connection section of watch chain on the watch chain and this two connecting portion be provided with respectively and make the table body of table and the connecting pin that watch chain connects as one by each connecting hole, have at least a side to put into turn in said two connecting holes, the fixedly connected pin of effect of the internal diameter by this turn, and to establish in a side of connecting pin or both sides can be the rotating part that connecting pin rotates.

In addition, because connecting pin is to insert while rotating or take out along the direction identical with the spooling direction of turn, when field-strip, also can take out connecting pin simply effortlessly, and each connector of his-and-hers watches is difficult for causing scar, connecting pin can also not make things convenient for maintenance because of removal force flexural deformation yet.

Another technical scheme of table of the present invention is, be arranged in the set connection in table body both sides with showing the body connecting portion, being arranged at the connecting hole of the lateral direction penetrating that connection section of watch chain on the watch chain and this two connecting portion be provided with respectively, have at least a side to put into turn in said two connecting holes, insert two screw-like connecting pins respectively from both sides when being a straight line in that above-mentioned connecting hole is corresponding, and the fixedly connected pin of effect of the internal diameter by this turn, make two connecting portions and becoming one.

In addition, because connecting pin is to insert while rotating or take out along the direction identical with the spooling direction of turn, when field-strip, also can take out connecting pin simply effortlessly, and each connector of his-and-hers watches is difficult for causing scar, and connecting pin can be because of removal force flexural deformation yet.In addition,, just the outside portion of these two screw-like connecting pins can be designed to end, make design diversified greater than connecting hole owing to used two screw-like connecting pins.

Another technical scheme of table of the present invention is, can with any two adjacent connectors on the watch chain that links to each other of table body, wherein an end of each connector is established connecting portion, the other end is established the portion that is connected that connecting portion therewith is connected, and horizontal connecting hole is set respectively in two connecting portions, it is characterized in that having at least a side to put into turn in said two connecting holes, the fixedly connected pin of effect of the internal diameter by this turn, make the connecting portion and the portion of being connected on the watch chain become one, wherein the one or both ends of connecting pin are provided with the rotating part that this connecting pin is rotated.And establish screw thread on the surface of said connecting pin.

This connection structure one can make number of components and parts reduce, and the operation of assembling operation is oversimplified, and work efficiency improves greatly, thereby realizes that cost has alleviated the weight of watch chain when reducing; Number of components and parts reduces the outward appearance and the design that also can make watch chain and reaches the own aesthetic of being wanted.Two can effectively utilize the characteristic of spring, and fixedly connected simply pin makes its bed knife strengthen.And the weight saving of the integral body of feasible table, reduce the cost of showing.

Describe specific embodiments of the invention in detail below in conjunction with accompanying drawing.

Embodiment shown in Figure 1 is the connection structure of table of the present invention and the exploded perspective view shown in the table.As shown in the figure, the table body 1 of table is provided with the lug boss 2 that becomes table body connecting portion, and the connecting hole 3 of a lateral direction penetrating is set in this lug boss 2.The watch chain 4 of table is provided with the connection section of watch chain 4a that can be connected with table body 1, and the tip of this connection section of watch chain 4a is established the

teat

5,5 of bifilar shape, is respectively equipped with the connecting

hole

6,6 of lateral direction penetrating on this bifilar shape teat 5,5.The setting of three connecting

holes

6,3,6 should be when lug boss 2 stretches between the

bifilar shape teat

5,5, shape correspondence linearly, and can insert connecting pin 7 and make table body 1 and the watch chain 4 one state that is formed by connecting.

As shown in Figure 2, the setting of the inside diameter D 3 of the connecting hole 3 on the lug boss 2 of table body 1 is bigger slightly than the inside diameter D 6 of the connecting

hole

6,6 of connection section of watch chain 4a, and puts into cylindric turn 8 in advance in connecting hole 3.For this turn 8 can successfully be inserted in the connecting hole 3, the outer diameter D 8 (as shown in Figure 3) of turn 8 should be slightly less than inside diameter D 3.For example, if the inside diameter D of connecting hole 33 is 1.40mm, 8 of the outer diameter D of turn 8 should be set at 1.37mm.

The material of the connecting pin 7 in the present embodiment is that stainless steel is made, and as illustrated in figures 1 and 2, the central portion of connecting pin 7 is provided with a reducing diameter part 9, and the external diameter of this reducing diameter part 9 is smaller than the external diameter of other parts of connecting pin 7.In addition, the central portion of turn 8 is also established a minor diameter part 10.

In addition, as shown in Figure 2, the groove 7a, the 7a that establish yi word pattern respectively on two end faces of connecting pin 7 be as rotating part, and on the periphery at the two ends of connecting pin 7, establish inclined-plane 7b, 7b.On two lateral circle surfaces of reducing diameter part 9, be provided with inclined-

plane

7c, 7c too.

The setting of inclined-plane 7b, the 7b at connecting pin 7 two ends is the internal diameter that inserts the minor diameter part 10 of turn 8 for the ease of connecting pin 7, makes minor diameter part 10 relatively easily expand.The inclined-plane 7c of the both sides of reducing diameter part 9, the effect of 7c are, after connecting pin 7 and turn 8 are in a single day chimeric, when connecting pin 7 withdraws from the minor diameter part 10 of turn 8, strength extrusion that need not be very big or extract, minor diameter part 10 is expanded gradually by inclined-

plane

7c, 7c, taken out connecting pin 7.

It is that subminiature screwdriver rotates by connecting pin 7 that the effect of yi word pattern groove 7a, the 7a of both ends of the surface is to use head.Because the dilatational elasticity of turn 8 is limited, the difference of the outer diameter D 9 of the difference of the internal diameter S of the minor diameter part 10 of turn 8 and the inner diameter d 8 of turn 8 and the reducing diameter part 9 of connecting pin 7 and the outer diameter D 7 of connecting pin 7 does not have the words about 0.2mm, when connecting pin 7 was taken out from turn 8, required power was that 10 newton can realize.

Connecting pin 7 own possibility that drops from turn 8 under no external force effect can not take place in such structure, has good practicability.But when the surface of 8 pairs of connecting pins 7 of turn needs bigger acting force (for example being used under the situation of senior watch), the strength of this degree is with regard to some deficiency.

Acting force for 8 pairs of connecting pins 7 of reinforcement spring circle, this just needs the difference of outer diameter D 9 and the outer diameter D 7 of connecting pin 7 of the reducing diameter part 9 of the poor and connecting pin 7 between the inner diameter d 8 of the internal diameter S of minor diameter part 10 of turn 8 and turn 8 to surpass 0.2mm, this difference is big more, and connecting pin 7 is just difficult more when inserting or extracting turn 8.Following embodiment of the present invention solves this problem with the pin 7 that is rotationally connected exactly.

Principle is, when an end of turn 8 withstands fixed part, connecting pin 7 inserted while rotating towards the direction identical with the spooling direction of turn 8, and the internal diameter of turn 8 then can temporarily enlarge like this.For this reason, need a kind of more special instrument--small-sized screwdriver, the end of groove 7a, the 7a of the yi word pattern at this screwdriver and connecting pin 7 two ends is harmonious, makes screwdriver withstand the left end of connecting pin 7 in the present embodiment, insert while rotating towards the direction identical with the spooling direction of turn 8.Because the used thrust of screwdriver is horizontal direction, this just makes the right-hand member of turn 8 withstand the inboard of the teat 5 on connection section of watch chain 4a right side, generation prevents the friction force of turn 8 rotations, this friction force can be fixed in the right-hand member of turn 8 inboard of the teat 5 on connection section of watch chain 4a right side, can be so that turn 8 can not rotate along with connecting pin 7 rotations.

Connecting pin 7 contacts with the internal diameter of turn 8 along the direction rotation identical with the spooling direction of turn 8 time, then can produce friction force, the internal diameter that this friction force can spreader spring circle 8.Like this, at the external diameter of connecting pin 7 during, also can under the injury-free situation in surface, easily inject in the turn 8 than the big 0.05mm of the internal diameter left and right sides of turn 8.

Connecting pin 7 is in inserting connecting

hole

6,3 and 6 fully the time, and minor diameter part 10 tablings of reducing diameter part 9 and turn 8 are with the position of fixedly connected pin 7.At this moment, become one by connecting pin 7 between the table body 1 of table and the watch chain 4, and in a single day connecting pin 7 inserting in the turn 8, under the situation that does not have instrument (screwdriver), is impossible take out.

When connecting pin 7 takes out in turn 8, used principle is identical when inserting, promptly as shown in Figure 2, screwdriver and connecting pin 7 left ends are harmonious, when trying hard to recommend a little less than horizontal direction is used, towards the direction rotation identical, till coming out completely, the right-hand member of turn 8 gets final product until connecting pin 7 with the spooling direction of turn 8.In addition, use the groove 7a of connecting pin 7 right-hand members that connecting pin 7 also can from right side insertion or taking-up, in this case, withstand the groove 7a of right-hand member with screwdriver, inserting (when attention was inserted from the right side, the sense of rotation of screwdriver was opposite with the direction of inserting from the left side) while rotating towards the direction identical with the spooling direction (from the right side) of turn 8 can realize.

This method can be so that the surface of the internal diameter of turn 8 and connecting pin 7 be all injury-free and durable in use.In addition, owing to be provided with reducing diameter part 9, also be provided with minor diameter part 10 in the central authorities of turn 8 at the middle part of connecting pin 7, both phase embeddings and the time, can produce the sensation of spring sudden contraction, be convenient to determining of connecting pin position.

In sum, the process of whole assembling operation is as follows:

Table body 1 that connects table and watch chain 4 be connected operation the time, at first turn 8 is put into the connecting hole 3 of the lug boss 2 of table body connecting portion, then the

bifilar shape teat

5,5 of the connection section of watch chain 4a of watch chain 4 is placed in the outside of the lug boss 2 of table body, and each connecting

hole

6,3 and 6 is laterally communicated be a straight line, the end with connecting pin 7 inserts from left side connecting hole 6 then.

Connecting pin 7 is when connecting hole 6 inserts the internal diameter of turns 8, and screwdriver withstands the yi word pattern groove 7a of connecting pin 7 left ends, and along continuous straight runs rotates while pushing away, and its sense of rotation should be identical with the spooling direction (the spooling direction of seeing from the left side) of turn 8.When connecting pin 7

inserts connecting hole

6,3 and 6 fully, minor diameter part 10 embedding mutually of the reducing diameter part 9 of connecting pin 7 and turn 8 can produce the sensation of spring sudden contraction, after this sensation takes place, the operation that is connected of table body 1 and watch chain 4 is promptly finished, and the two also becomes one structure.

For make connecting pin 7 toward the internal diameter of connecting

holes

6,6 and turn 8 while rotating insertion process smooth, the setting of the inside diameter D 6 of connecting hole 6 and the inner diameter d 8 of turn 8 should be more bigger than the outer diameter D 7 of connecting pin 7.For example, if when the external diameter of the connecting pin 7 of present embodiment is set at 1.04mm, the inner diameter d 8 of turn 8 should be 1.05mm, and D6 should be 1.10mm.The length L 8 of turn 8 should be roughly the same with the width of the lug boss 2 of showing the body connecting portion.

In addition, as mentioned above, the inside diameter D 6 of the connecting

hole

6,6 of the connection section of watch chain 4a of present embodiment is 1.10mm, when the inside diameter D 3 of connecting hole 3 is 1.40mm, 8 of the outer diameter D of turn 8 are set at 1.37mm, this setting can to stop laterally moving of turn 8, can produce left end or the right-hand member of friction force in order to fixing spring circle 8 at the left end or the right-hand member of turn 8 simultaneously so that putting into the two ends of the turn 8 of connecting hole 3 is withstood by the inner edge of connecting

hole

6,6.

In addition, the internal diameter S of the minor diameter part 10 of turn 8 is set at 0.90mm, and the external diameter of the reducing diameter part 9 of connecting pin 7 is made as 0.80mm.When external diameter is that the connecting pin 7 of 1.04mm is by the footpath during for the minor diameter part 10 of the turn 8 of 0.90mm, the inclined-plane 7b and the minor diameter part 10 of one end are collided, by the rotation identical with the spooling direction of turn 8 of the horizontal thrust of screwdriver with the edge, make minor diameter part 10 expand, 7 of connecting pins can insert smoothly.

Like this, connecting pin 7 also can not drop out from connecting hole 3 at the situation lower spring circle 8 that does not take out connecting pin 7 in the minor diameter part 10 that can waltz through turn 8.In addition, because the elastic reaction of minor diameter part 10, when embedding the reducing diameter part 9 of connecting

7,7 of connecting pins are fixed in the turn 8.

In addition because connecting pin 7 is difficult to insert when not rotating, such as when the outer diameter D 7 of connecting pin 7 be 1.00mm, when the internal diameter S of minor diameter part 10 was 0.95mm, though differing from therebetween has only 0.05mm, connecting pin 7 can successfully be inserted then needed certain method.In the present embodiment, insert owing to adopted while rotating, with the method that very little power can be loaded and unloaded, the difference of above-mentioned D7 and S can reach 0.14mm.Like this, then can strengthen with the bed knife of the chimeric generation of the reducing diameter part 9 of connecting pin 7 by the minor diameter part 10 of turn 8.Under the situation of this strong bed knife, if do not rotate connecting pin 7 is taken out, then need the above power of 30 newton; If the employing rotation mode then only needs the following power of 10 newton to get final product.

When method connected the table body 1 of table and watch chain 4 thus, number of components and parts was few, cost is low, high efficiency.Because turn 8 is stronger with the inlay resultant force of connecting pin 7, makes connecting portion comparatively stable.In addition, because the job operation of each connecting

hole

6,3,6 is simple, simultaneously, connecting

portion

5,2,5 can design to thin type, has just strengthened each connecting portion attractive in appearance of table.The rotation that is arranged so that connecting pin 7 of inclined-plane 7b is inserted more or less freely, and the setting of inclined-

plane

Second embodiment of the present invention such as Fig. 4, shown in Figure 5, the part identical with first embodiment illustrates with prosign.

This embodiment as shown in Figure 4 and Figure 5, form by two screw-like connecting pins 11,11 ' of the turn 15 of the minor diameter part 15a that has the wide cut broad and two similar screw shapes and to be connected apparatus, wherein two screw-like connecting pins 11, an end of 11 ' are provided with reducing diameter part 13,13 ', are used for inserting turn 15.After the insertion, then can form 14,14 and central minor diameter part 15b of two minor diameter parts.

Two screw-like connecting pins 11,11 ' structure are as shown in Figure 4, one end is the bigger head of diameter 12,12 ', the other end then is the undergauge all 13,13 ' of path, and establish groove 11b, the 11b ' that is yi word pattern at the small end end face, on head 12,12 ' outer face, also be provided with yi

word pattern groove

11a, 11a '.

Table body 1 and the watch chain 4 of table are when being connected operation, identical with first embodiment, earlier turn 15 is put into connecting hole 3 (as shown in Figure 5), then the

bifilar shape teat

5,5 of the connection section of watch chain 4a of watch chain 4 is placed in the outside of the lug boss 2 of table body 1, and after each connecting

hole

6,3 and 6 laterally being communicated be a straight line, a connecting pin 11 is inserted while rotating towards the direction identical with the spooling direction of turn 15 from a side, and another connecting pin 11 ' inserts in the turn 15 in the same way from opposite side.Two connecting pins 11,11 ' use screwdriver when inserting, this screwdriver is corresponding with

groove

11a, 11a ' respectively, inserts while rotating from both sides along the direction identical with the spooling direction of turn 15.

But, when take out two screw-like connecting pins 11,11 ' time, its method is different with first embodiment.At first, screwdriver is withstood an end connecting pin 11 to be rotated along the direction opposite with direction of insertion, at this moment, the spooling direction contrary of the sense of rotation of connecting pin 11 and turn 15, during rotation, the inboard of the outside surface of connecting pin 11 and turn 15 produces friction force, makes turn 15 produce the surface that convergent force tightly is around in connecting pin 11, and turn 15 just might be along with connecting pin 11 rotates together like this.But because turn 15 has also been fixed the connecting pin 11 ' of the other end, so 15 of turns can not rotate with connecting pin 11, the connecting pin 11 in left side just can take out.

After the screw-like connecting pin 11 of an end takes out, when taking out the connecting pin 11 ' of the other end, then can not utilize the groove 11a ' of head 12 ' outer end, this be because, principle is identical as the aforementioned, in case the outer end at connecting pin 11 ' rotates towards the direction opposite with direction of insertion with screwdriver, will make turn 15 no fixed-sites and rotation together.Therefore, when taking out connecting pin 11 ', be to utilize groove 11b ' to make connecting pin 11 ' rotation, open the internal diameter of turn 15 with expansion.So be equipped with yi

word pattern groove

11b, 11b ' at connecting pin 11,11 ' small end face.

Specifically, after the connecting pin 11 in left side takes out, screwdriver is corresponding with the small end groove 11b ' of another connecting pin 11 ', see from the left side along the direction identical and rotate while pushing away with the spooling direction of turn 15, make the end on right side of turn 15 lean on mutually, produce friction force in order to fixing spring circle 15 with the inside surface of the teat 5 on connection section of watch chain 4a right side.In addition, the friction force that internal diameter produced of the surface of connecting pin 11 ' and turn 15 makes the internal diameter expansion of turn 15, then can easily take out connecting pin 11 '.Certainly, use the same method, behind the taking-up connecting pin 11 ', also can earlier at taking-up connecting pin 11.

Usually, when being screwed object, have the worry of screw loosening, the structure of picture present embodiment--utilize the elasticity of turn 15 to fix two screw-like connecting pins 11,11 ' surface, loosening phenomenon then can not appear, even it also is that turn 15 is unitary rotation with connecting pin 11,11 ' that connecting pin 11,11 ' rotates, connecting pin 11,11 ' drop can not taken place.Only make two screw-like connecting pins 11,11 ' counter-rotating mutually, perhaps an end is fixed under the situation of end rotation, just can make 11,11 ' loosening, the taking-up of two screw-like connecting pins.

In the present embodiment, the inside diameter D 3 of connecting hole 3 is made as 1.40mm, and the inside diameter D 6 of connecting

hole

6,6 is made as 1.10mm; The outer diameter D 15 of turn 15 is 1.37mm, and the internal diameter of minor diameter part 15a is 0.90mm; Two screw-like connecting pins 11,11 ' external diameter are 1.04mm, and undergauge 13,13 ' external diameter are set at 0.80mm.
