CN2264505Y - Watch strap fastener - Google Patents

Abstract

The utility model relates to a watch strap fastener which is composed of a body piece, condense pieces and clip members assembled together, wherein, the two condense pieces are hinged at both ends of the body piece and form an opposite arc against the body piece, and the two clip members are respectively hinged at the other ends of the two condense pieces to hold the watch strap; elastic pieces are formed by cut in the middle of both ends of the body piece, and elastic pieces of the condense pieces corresponding to the body piece are extended in a convex manner with a stitching block capable of pressing the elastic pieces down. When the condense pieces are screwed towards the upper end surface of the body piece, the stitching block presses down the elastic pieces; the action of the elastic force of the elastic pieces causes the condense pieces to stitch in an elastic manner on the end surface of the body piece, which causes the draw bundle of the watch strap to shrink tightly; the watch is fastened more firmly and can not be loosened, and the end of the strap watch can not be curved outwards.

Description

Retaining construction of watchband

The utility model relates to a kind of retaining construction of watchband, is meant that especially a kind of condensation sheet is elasticity and is pressed together on main body sheet upper surface, thus the stressing that reaches watchband tightly receive, can more firmly and not can the person of getting loose.

A kind of retaining construction of watchband device commonly used at present as shown in Figure 1 and Figure 2, it mainly is provided with a lower piece 10, these lower piece 10 lefts are provided with a locking edge 100, these lower piece 10 tops are covered with a upper cover plate 11 again, these upper cover plate 11 below projections have a cramp 110, but nationality is held on the locking edge 100 of lower piece 10 by these cramp 110 embeddings, and hanging support is on wrist for making watchband be fastened into ring.But, thisly be fastened on the mode of locking edge 100 with cramp 110, as using the back or clash into because of carelessness when watchband is buckled through long-time, this cramp 110 can be outer opening and be out of shape, and loses the effect of original stably fastening.And when watchband or wrist a little firmly the time, then this cramp 110 is promptly thrown off this locking edge 100 and watchband is thrown off, the anxiety that wrist-watch is had drop.Another kind of retaining construction of watchband device as shown in Figure 3, be provided with leather watchband 20,21, these leather watchband 20 ora terminalis are equipped with clasp 22 and fibula 23, and another leather watchband 21 is provided with perforation 24, nationality wears clasp 22 by watchband 21, makes its fibula 23 plug perforation 24 and group is buckled two leather watch chains 20,21.This group of button mode must singlehandedly be carried out, relatively difficulty and trouble, though and group button back watchband 21 is terminal has skin ring 25 covers to hold, these skin ring 25 easy displacement or fractures, and making that watchband 21 is terminal can the outwards curling aesthetic feeling that disfeature.

The purpose of this utility model provides drawing of a kind of watchband and buckles the retaining construction of watchband that more firmly and relatively can not get loose, and its end can outwards not curl and more attractive in appearance.

The utility model is achieved in that and includes main body sheet, condensation sheet and clip member, it is characterized in that: the two ends of aforementioned body sheet are respectively equipped with two groovings, establish in the middle of this two grooving to be flexure strip; Two condensation sheets are assembled in two ends of main body sheet, and the flexure strip of the corresponding main body sheet of one end prolongs the protruding pressing block that has, and this pressing block end is extended with and supports edge; Two clip members are assembled in the outer end of condensation sheet, and it is mainly constituted by a clamping seat and a clamp.

Wherein the main body sheet is a curved arc shape, and the corresponding main body sheet of condensation sheet and be the opposite arc song.

Wherein the main body sheet is established in the upper surface and is a supporting face, and both side edges is established the edge that protects that is to the fovea superior folding, and the relative outside of two groovings upsweeps and is hinge hole.

Wherein the pressing block of condensation sheet is provided with axis hole, and the other end curls downwards and is a hinge hole.

Wherein there is row's shape latch the clamping seat both sides of clip member to recessed folding, and the protruding protruding axle that has is prolonged in the perforation of the corresponding clamping seat in these latch two ends.

Condensation sheet of the present utility model to main body sheet upper surface revolve by the time, pressing block promptly is and presses down flexure strip, and be subjected to the elastic restoring force effect of flexure strip, make the condensation sheet be elasticity and be pressed together on main body sheet upper surface, and then reach watchband tightly reel bundle, can be convenient simple and easyly firmly and not can get loose, and its clip member clamping leather belt of nationality, leather watchband end can outwards not curled and more attractive in appearance.
