Technical Field

The utility model relates to a watchband, in particular to a composite elastic watchband with a memory metal core.

Background

The watchband is an essential accessory on products such as a watch, and is a general name for fixing the effective part of the wrist of the watch. Currently, the watchbands are mainly made of flexible materials such as leather or plastics, or made of hard materials such as metal or ceramic in the form of links hinged to each other, and these watchbands are generally fastened at both ends of the watchband by means of a buckle, or elastic plastics are added to eliminate the buckle.

However, when the watchband is used, in order to relatively fix the position of the wrist, a relatively tight buckle is often needed to enable the watchband to be closely attached to the skin, but the watchband is uncomfortable to wear for a long time, and especially when the temperature in summer is relatively high, the skin of the wrist is red, swelling or rash easily caused; after the watch is relaxed, the wrist watch can rotate in the wrist part due to overlarge gap between the watchband and the wrist, so that the watch is inconvenient to watch in time, the external image is influenced, and inconvenience is caused to the working and living processes.

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.
