Detailed Description
In order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the present utility model easy to understand, the technical solutions in the embodiments of the present utility model are clearly and completely described below to further illustrate the present utility model, and it is obvious that the described embodiments are only some embodiments of the present utility model, not all versions.
As shown in fig. 1 to 3, a composite elastic wristband includes a wristband 1 and a memory metal core 2, wherein the memory metal core 2 is covered by the wristband 1, and the memory metal core 2 is waved in the length direction of the wristband 1.
By implanting the memory metal core 2, and setting the memory metal core 2 to be wavy in the length direction of the watchband 1, after the watchband 1 is buckled around the wrist, the memory metal core 2 can prop up the watchband 1, the wrist is generally elliptical and dynamically changes along with the movement of the palm and fingers, so that the watchband 1 is in partial contact with the skin of the wrist, and the contact position dynamically changes along with the movement of the hand, the watchband 1 can be prevented from being tightly adhered to the skin in a large area, and discomfort caused by long-time wearing is avoided; the memory metal core 2 is in a wave shape in the length direction of the watchband 1, so that the watchband 1 is easier to bend into a ring shape around the wrist, the watch is convenient to wear to the wrist, and meanwhile, the watchband 1 can be elastic in the length direction, so that the wearing comfort of the watchband 1 and the service life of the watchband 1 are improved.
Since the middle part of the watchband 1 generally needs to be provided with buttonholes or other fastening components, in order to ensure the uniformity of the stress and the weight of the watchband 1, the memory metal cores 2 are preferably surrounded into a ring shape in consideration of the convenience of processing, that is, the two rows of wave-shaped memory metal cores 2 are formed in parallel in the length direction of the watchband 1, of course, the memory metal cores 2 can be arranged in one row, or in two rows, even three rows, four rows and the like by using two independent memory metal cores, and the quantity can be set according to practical situations.
For the convenience of manufacturing the memory metal core 2 and the reduction of cost, the cross section of the memory metal core 2 is preferably circular, and of course, the cross section of the memory metal core 2 can be in other shapes such as ellipse, semicircle, triangle, square, etc.
In this embodiment, the width W of the wristband is 22mm, the wave-shaped wavelength l=9.27 mm≡0.421W of the memory metal core 2 in the longitudinal direction of the wristband 1, the wave-shaped wave height h=2 mm≡0.091W of the memory metal core 2 in the longitudinal direction of the wristband 1, and the diameter of the memory metal core 2 is 3mm.
The watchband 1 is preferably formed by clamping and cladding the memory metal core 2 after the lower watchband 11 and the upper watchband 12 are glued as shown in fig. 2, but of course, a mode of directly forming the memory metal core 2 by hot melting and cladding can also be directly adopted, and only the memory metal core 2 needs to be clad in the watchband.
As shown in fig. 3, the memory metal core 2 may be formed in a ring shape around the outer edge of the wristband 1, or may be provided in a partial section as shown in the lower side of fig. 2, if necessary.
The memory metal core 2 may be made of nickel-titanium or copper-based memory alloy in the prior art.
Having described the main technical features and fundamental principles of the present utility model and related advantages, it will be apparent to those skilled in the art that the present utility model is not limited to the details of the above exemplary embodiments, but may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The above detailed description is, therefore, to be taken in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
