Abstract
The utility model discloses a shape memory alloy watchband which comprises a shell material layer and a memory alloy material layer which is embedded into the shell material layer and is made of a nickel-titanium or copper-based memory alloy material, wherein the memory alloy material layer is shaped like an elastic sheet or filament. The shape memory alloy watchband is provided with the embedded shape memory alloy layer, has the advantages of large elasticity, high tensile strength, corrosion resistance, environmental protection and the like, and is relatively convenient to wear, unlikely to fall and long in service life.
Description
Technical field
This practicality relates to a kind of watchband, relates in particular to a kind of marmem watchband.
Background technology
Watchband is necessary accessory on the products such as wrist-watch, current watchband is mainly to utilize the flexible material such as leather or plastics to make, or made with hinged each other chain link form by the hard material of for example metal or pottery, these watchbands are generally to utilize buckle-type to carry out watchband two ends to be fixedly connected with, or in addition thereby elastoplast is exempted buckle, but this mode or dress cumbersomely, or because hardness is too large, elasticity is not enough and easily damage or come off.
Utility model content
The purpose of this utility model is the deficiency for prior art scheme, a kind of good springiness is provided, dresses the marmem watchband convenient, stretching resistance is strong.
For achieving the above object, the technical scheme that the utility model provides is: a kind of marmem watchband is provided, by sheathing material layer and be embedded employing NiTi in sheathing material layer or the memory alloy material layer of copper-based memory alloy material forms, described memory alloy material layer be shaped as shell fragment shape or filament shape.
Described sheathing material layer be shaped as strip, watchcase fixed bit can also be set on sheathing material layer.
Described marmem watchband is closed loop or the non-closed watchband that leaves space.
The beneficial effects of the utility model are, watchband is embedded with shape memory alloy material layer, have that elasticity is large, stretching resistance is strong, an advantage such as corrosion-resistant, environmental protection, and it is long to dress more convenient, difficult drop-off, pot life.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Nitinol or acid bronze alloy are two kinds of common shape memory alloy materials, it is the special alloy that the plastic deformation of self automatically can be reverted under a certain specified temp to original-shape, particularly Nitinol, there is the excellent characteristics such as wear-resistant, anticorrosive, high damping and super-elasticity, its expansion and contraction is more than 20%, reach 7 powers of 1*10 fatigue life, damping characteristic is higher 10 times than common spring, its corrosion resistance is better than best medical stainless steel at present, is a kind of very outstanding functional material.
Shown in figure 1 and Fig. 2, the utility model embodiment provides a kind of marmem watchband, by sheathing material layer 11 and be embedded employing NiTi in sheathing material layer 11 or the memory alloy material layer of copper-based memory alloy material forms, described memory alloy material layer be shaped as shell fragment shape memory alloys material layer 13 or filament shape memory alloys material layer 12.
Shown in figure 3 and Fig. 4, described marmem watchband is closed loop or the non-closed watchband that leaves space.
Shown in figure 5-7, described sheathing material layer 11 be shaped as strip, watchcase fixed bit can also be set on sheathing material layer, in order to fixing watchcase 200.
Owing to being embedded with shape memory alloy material layer, marmem watchband is in the time of low temperature as below 0 degree Celsius time, and elasticity is poor, can stretchingly be out of shape, and, restore to the original state, and elasticity is larger when above at 10 degree Celsius.(because human body has uniform temperature) when higher temperatures like this, memory watchband can remain two ends clasp is tightened up, and not yielding.
Thus in conjunction with Fig. 1-7, the advantage such as memorial alloy watchband described in the utility model has that elasticity is large, stretching resistance is strong, corrosion-resistant, environmental protection, and also it is long to dress more convenient, difficult drop-off, pot life.
The above; it is only preferably detailed description of the invention of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
Claims (3)
