Abstract

The utility model provides a straining buckle which comprises a buckle body (1) and straining strips (2), wherein the buckle body (1) is an elastic plastic injection molded part with a thin small through hole (3), two straining strips are penetrated through the identical thin small through hole (3), the addition of the diameters of the two straining strips (2) is larger than the diameter of the thin small through hole (3). The utility model is a straining buckle that the structure is simple, the utility model can be performed mass and quick manufacture, the cost is low, the volume is small, and the use is convenient and reliable.

Description

Strainer

The utility model relates to a kind of strainer that is used on bangle, necklace, the raincoat elastic cord.

At present, a kind of strainer that has that uses on the bangle is to be woven into a long slightly knot with cord by craft, elastic cord pushes through from the finedraw of knot, the relative knot pulling of elastic cord has certain frictional resistance, and this strainer obviously has the shortcoming that braiding is consuming time, cost is high and knot easily unclamps the weak point in service life; A kind of strainer that uses on the raincoat elastic cord is that the elastic force with spring makes pressure withhold elastic cord by the strainer through hole, thereby make the pulling of the relative strainer of elastic cord have certain resistance, this strainer has complex structure, cost height, shortcoming that volume is bigger.

The purpose of this utility model provide a kind of simple in structure, be convenient to a large amount of to produce fast, cost is low, volume is small and exquisite, easy to use and reliable strainer.

To achieve these goals, technical solution of the present utility model is this: a kind of strainer, comprise button, elastic cord two parts, wherein button is the elastoplast moulding that has a tiny through hole, article two, elastic cord passes same tiny through hole, and the diameter sum of two elastic cords is greater than the diameter of tiny through hole.

Because in the above-mentioned technical solution, article two, the diameter sum of elastic cord is greater than the diameter of tiny through hole, therefore when two elastic cords pass same tiny through hole, elastic cord must be subjected to the certain extruding force of through-hole wall, this pressure makes elastic cord only just can overcome friction when being subjected to the external force pulling and moves relative to strainer, button is convenient to a large amount of productions fast by injection molded this product that makes of elastoplast, thereby the tiny through hole that also makes button has better elasticity makes the pressure stability of tiny through hole to elastic cord, reliably, thus this strainer have simple in structure, be convenient to a large amount of productions fast, cost is low, easy to use and reliable characteristics.

Below in conjunction with drawings and Examples the utility model is described in further detail:

The shape assumption diagram of the button of the strainer that Fig. 1 provides for the utility model.

Fig. 2 is the side view of Fig. 1.

Fig. 3 is the A-A cutaway view of Fig. 2.

Cut-away diagram when Fig. 4 is used for the button of strainer and elastic cord.

Wherein: 1, button; 2, elastic cord; 3, tiny through hole; 4, projection; 5, concave point; 6, big endoporus place; 7, little endoporus place; 8, central axis.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the strainer that the utility model provides comprises button 1, elastic cord 2 two parts, button 1 is for having the elastoplast moulding of a tiny through hole 3, article two, elastic cord 2 passes the diameter of the diameter sum of 3, two elastic cords 2 of same tiny through hole greater than tiny through hole 3.This strainer is no matter be that strainer or the relative spring force strainer that braiding relatively forms all has the advantage that significantly substitutes.

In order further to realize result of use of the present utility model, length direction at the outer surface upper edge of button 1 button 1 is provided with several projection 4 and concave points 5, projection 4 these places of expression are far away relatively from the central axis 8 of button 1, concave point 5 these places of expression are nearer relatively from the central axis 8 of button 1, as shown in Figure 1, these button outer surfaces are provided with projection 4 and concave point 5 can produce the effect that a kind of waveform rises and falls from monnolithic case, these projectioies 4, concave point 5 except having benefit attractive in appearance, also make button 1 in use hand hold and be difficult for skidding.

As shown in Figure 3, Figure 4, in order to produce the elastic pressure effect of 3 pairs of elastic cords 2 of tiny through hole better, the tiny through hole 3 that makes button 1 has the bigger relatively relative smaller difference with endoporus of endoporus along the length direction of button 1 in different positions, wherein big endoporus place 6 place's endoporus are relatively large, the endoporus at little endoporus place 7 is less relatively, the effect by the elastic cord 2 at this place of 7 pairs at little endoporus place is near the effects of local small spring, than be easier to form a kind of can tension the yet rubber-like buckle press of pine excessively.

For attractive in appearance, practical consideration, can as required button 1 be designed to oval cylinder or approaching oval cylinder, tiny through hole 3 is provided with along the central axis 8 of oval cylinder.

Claims
