Specific embodiment
In order to be illustrated more clearly that the technical solution of the utility model, below in conjunction with drawings and Examples, new to this practicality
The technical scheme of type be further elaborated it should be apparent that, below description be only of the present utility model some enforcement
Example, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to these embodiments
Obtain other embodiments.
Referring to figs. 1 to Fig. 3, steel band table that is a kind of extensible and shortening is buckled, for the fastening of the wrist-watch using steel watchband,
Including base plate 1 processed, cover 2, coremaking 3;Described base plate processed 1 be respectively arranged at two ends with a cover 2;Described base plate processed 1 with each
Be respectively equipped with a coremaking 3 between individual cover 2, one end of described coremaking 3 is articulated and connected with base plate 1 processed, described coremaking 3 another
End is articulated and connected with cover 2;It is provided with each cover 2 and slidably extend piece 4 and be arranged on this cover 2 and extend piece
Spring clip 5 between 4;This elastic pressuring plate 5 can be constituted using monolithic leaf spring;Base plate 1 processed be respectively arranged at two ends with limiting tooth 6,
This limiting tooth 6 is used for limiting the relative position extending between piece 4 and base plate processed 1, and each prolongation piece 4 is towards the one side of base plate 1 processed
It is provided with multiple rows of length adjustment tooth 7 mating with limiting tooth 6;Preferably, extend piece 4 and be provided with four groups of length adjustment teeth along its length
7, base plate 1 processed be respectively arranged at two ends with one group of limiting tooth 6;When cover 2 is fastened on base plate 1 processed, elastic pressuring plate 5 will extend piece 4
Suppress downwards so that length adjustment tooth 7 is engaged with limiting tooth 6 so that the relative position extending between piece 4 and base plate processed 1 keeps steady
Fixed, that is, keep the length stabilisation of steel band, realize stably wearing;Steel band is connected to by raw ear nail and extends the end of piece 4 and prolong
The end of lengthy motion picture 4 is provided with the breach for housing steel band.When needing the length adjusting steel band, it is lifted up compressing by extending piece 4
Elastic pressuring plate 5 makes length adjustment tooth 7 depart from limiting tooth 6, and extending piece 4 can relative cover 2 and the length direction along cover 2
Mobile, adjustment extends prolongation or shortening with the relative position of cover 2 to realize steel band for the piece 4, adjusts extending piece 4 to suitable position
When putting, decontrol and extend piece 4, elastic pressuring plate 5 recovers to make the length adjustment tooth 7 extending piece 4 again to the compression extending piece 4
It is engaged with limiting tooth 6 and block.
In one embodiment, extend piece 4 is respectively provided on two sides with raised 8, and the madial wall of cover 2 is provided with and raised 8
The kidney-shaped groove of coupling is so that prolongation piece 4 can be in the inside slide anteroposterior of cover 2.After prolongation piece 4 is assembled in cover 2, prolong
The projection 8 of lengthy motion picture 4 both sides is respectively clamped in the kidney-shaped groove of cover 2 madial wall, the cunning of the length of this kidney-shaped groove and prolongation piece 4
Dynamic stroke matches, and when extending the pressure that piece 4 overcomes elastic pressuring plate 5 by external force intervention, extends piece 4 and passes through to extend 4 liang of piece
The guide effect of the projection 8 of side moves forward and backward along kidney-shaped groove, thus realizing adjusting the length of steel band.
In one embodiment, because elastic pressuring plate 5 has radian, with the prolongation direct contact area of piece 4 less, energy
The enough frictional force producing is limited, leads to table to buckle inefficacys when receiving larger external force effect it is possible to skid, for this reason, extend piece 4 and
The surface of elastic pressuring plate 5 contact, along three raised lines 9 of the length direction setting extending piece 4, passes through this three by this prolongation piece 4
Raised line 9 keeps the effective contact with elastic pressuring plate 5.
In one embodiment, base plate 1 processed is provided with the horizontal groove 10 for installing flexible fastening system, and stretch button
The locking nail 11 that assembly system includes being arranged on cover 2, two panels combination are arranged in horizontal groove 10 and are used for fastening locking nail 11
Stretchable sheet 12 and for limit telescopic piece 12 pressing plate 13, be provided with coil tension spring support telescopic between two panels stretchable sheet 12,
Every stretchable sheet 12 is provided with and limits the flexible waist-shaped hole being formed, and is provided with the locating dowel 14 mated with waist-shaped hole, pressure in horizontal tub
Plate 13 abutting is fixed in locating dowel 14 and pressing plate 13 is provided with for the through hole by locking nail 11.Specifically, two covers 2
The free end end of locking nail 11 is respectively provided with the breach fastening stretchable sheet 12, and two panels stretchable sheet 12 is l type platy structure,
Vertical edges press for convenience of user, and horizontal sides are provided with the opening direction phase of u notch and the u notch of two panels stretchable sheet 12
Right, and the outer side edges of the u notch of two panels stretchable sheet 12 mutually charge in the u notch of other side, and two u notches
The cross section size being smaller than locking nail 11 between outer side edges, when cover 2 is fastened on base plate 1 processed, locking nail 11
Breach is firmly blocked by the outer side edges of the u notch of stretchable sheet 12, realizes the fastening that table is buckled;Pressing stretchable sheet 12 makes two panels stretch
Contracting piece 12 move toward one another, locking nail 11 departs from the screens locking of stretchable sheet 12.
In one embodiment, for convenience of installing, locating dowel 14 is provided with screwed hole, and pressing plate 13 is fixed by screw locking
In locating dowel 14.
In one embodiment, the finite volume buckled due to table, for saving space, coremaking 3 is H type structure, base plate 1 processed
The connection boss being respectively arranged at two ends with for connecting coremaking 3.Locking nail 11 grade part is stepped down by the H type structure of coremaking 3 and is pacified
Dress, drastically increases the internal structure compactness of product.
The utility model is respectively arranged to adjust the prolongation piece of steel band length by buckleing two ends in table, is extended by upper lift
Piece adjusts the occlusal position of length adjustment tooth and limiting tooth, realizes extending slide anteroposterior regulation in cover for the piece, realizes steel band
The adjustment of length.
The above is only preferred embodiment of the present utility model it is noted that common skill for the art
For art personnel, on the premise of without departing from the utility model principle, some improvements and modifications can also be made, these improve and
