Description

Length-adjustable chain jewellery
Technical field
The utility model relates to jewellery technical field, refers in particular to a kind of length-adjustable chain jewellery.
Background technology
Chain jewellery include bangle, necklace etc., and generally, it adopts fixing length, and buyer needs bangle or the necklace of selecting different length according to the demand of self, has relative limitation; Another kind of mode is when needing the length reduction by necklace or bangle, to be dismantled a wherein part, operate cumbersome, need professional to dismantle by pliers or other instruments; And when needs increase length again, equally still need to be operated by professional.Visible, this way of prior art causes inconvenience extremely to user.
Utility model content
Based on this, the utility model is to provide a kind of length-adjustable chain jewellery, and it can overcome the defect of prior art, can the length of free adjustment chain jewellery, meets multiple demand.
Its technical scheme is as follows:
A kind of length-adjustable chain jewellery, it comprise strip chain main body, two the prolongation chains be connected with the two ends of described chain main body respectively, lock pearl, described locking pearl is provided with container cavity, elastomer is filled with in described container cavity, through hole runs through described locking pearl and described elastomer, article two, described prolongation chain is all through described through hole, and the diameter of described through hole is less than the lateral length sum of two described prolongation chains.
Below further technical scheme is described:
Preferably, the other end of described prolongation chain is provided with locating part, and the size of described locating part is greater than the diameter of described through hole.
Preferably, described through hole is cylindrical straight hole, the equal diameters at any place of described through hole.
Preferably, described through hole is cross section is circular column reducing hole, and described through hole is not more than the diameter of described through hole at described locking Zhu Chu at the diameter at described elastomer place.
Preferably, described through hole is square straight hole, and the length at any place of described through hole is equal.
Preferably, described through hole is square reducing hole, and described through hole is not more than the length of described through hole at described locking Zhu Chu in the length at described elastomer place.
Preferably, described elastomer is silica gel.
Preferably, the shape of described locking pearl is spherical, cube shaped, star or heart.
Below the principle, effect etc. of preceding solution are described:
Above-mentioned length-adjustable chain jewellery are at the inside filled elastomer of described locking pearl, and through hole is set, the free end extending chain is passed in described through hole, diameter due to through hole is less than the lateral length sum of two described prolongation chains, to be stuck in described through hole so extend chain and to be fixed on a certain position.When needing the length adjusting whole chain jewellery, pull any described prolongation chain or pull two described prolongation chains simultaneously, due to elastomeric elastic force, extending chain can produce extruding to elastomer, and the effect of power is contrary, elastomer also can produce corresponding squeezing action to prolongation chain, tightly wale prolongation chain, thus the effect of fixedly locked pearl can be played, therefore, locking pearl can being changed extending the position on chain, reaching the object adjusting whole chain jewellery length.
The regulative mode of the utility model length-adjustable chain jewellery is simple and convenient, and user and can need to adjust its length according to hobby when wearing, and easily wears, hoop power is good, difficult drop-off or unclamp, once after wearing, the phenomenon that also can not drop.

10, chain main body, 12a (12b), extends chain, and 14, locking pearl, 16, elastomer, 18, through hole, 20a (20b), locating part.
Detailed description of the invention
Below embodiment of the present utility model is described in detail:
As shown in Figures 1 and 2, a kind of length-adjustable chain jewellery, it comprises the chain main body 10 of strip, two prolongation chain 12a, 12b be connected with the two ends of described chain main body 10 respectively and lock pearl 14, described locking pearl 14 is provided with container cavity, elastomer 16 is filled with in described container cavity, through hole 18 runs through described locking pearl 14 and described elastomer 16, article two, described prolongation chain 12a, 12b are all through described through hole 18, and the diameter of described through hole 18 is less than the lateral length sum of two described prolongation chain 12a, 12b.
Described length-adjustable chain jewellery are less than the lateral length sum of two described prolongation chain 12a, 12b due to the diameter of through hole 18, to be stuck in described through hole 18 so extend chain 12a, 12b and to be fixed on a certain position.When needing the length adjusting whole chain jewellery, pull described prolongation chain 12a or extend chain 12b, or pull two described prolongation chain 12a simultaneously, 12b, due to the elastic force of elastomer 16, extend chain 12a, 12b can produce extruding to elastomer 16, and the effect of power is contrary, elastomer 16 also can to prolongation chain 12a, 12b produces corresponding squeezing action, tightly wale prolongation chain, thus the effect of fixedly locked pearl 14 can be played, therefore, locking pearl 14 can be changed at prolongation chain 12a, position on 12b, reach the object adjusting whole chain jewellery length.
One end of described prolongation chain 12a, 12b is connected with described chain main body 10, and its other end is provided with locating part 20a, 20b, and the size of described locating part 20a, 20b is greater than the diameter of described through hole 18.Size described herein comprises length, width, diameter, and object is when pulling described prolongation chain 20a, 20b, avoids prolongation chain 12a, 12b to be surprisingly pulled away from described through hole 18.
Wherein in an embodiment, described through hole 18 is cylindrical straight hole, the equal diameters at any place of described through hole 18; In another embodiment, described through hole 18 for cross section be circular column reducing hole, described through hole 18 is not more than the diameter of described through hole 18 at described locking Zhu14Chu at the diameter at described elastomer 16 place, enable described prolongation chain 12a, 12b under the flexible effect of described elastomer 16, be restricted in described through hole 18.
In a further embodiment, described through hole 18 is square straight hole, and the length at any place of described through hole 18 is equal; In another embodiment, described through hole 18 is square reducing hole, described through hole 18 is not more than the length of described through hole 18 at described locking Zhu Chu in the length at described elastomer 16 place, enable described prolongation chain 12a, 12b under the flexible effect of described elastomer 16, be restricted in described through hole 18.
Described elastomer 16 is preferably silica gel.The shape of described locking pearl 14 is spherical, cube shaped, star or heart; The shape of described prolongation chain 12a, 12b and described chain main body 10 can arrange arbitrary shape according to hobby, but the surface extending the shape of chain 12a, 12b needs relative smooth, can not limit extend chain 12a, 12b pull and with the elastic compaction of elastomer 16.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this description is recorded.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
