Abstract
The utility model relates to an adjustable curling rigid wire, wherein, the wire is provided with a plurality of expanding canals; the top angular line of the expanding canal is perpendicular to the portrait of the wire, which is provided with an expanding wedge; twin used strands are reverse spirally wound on the wire, and through the expanding wedge; one ends of the twin used strands are fixed on one end of the wire, the other ends of which are connected with the euphroe which is positioned at the other end of the wire. Operating the euphroe, drawing in or giving out the thread, and adjusting the pressure the expanding wedge on the skirt board of the expanding canal can adjust the inherent stress of the wire, adjust the curling rigidity of the wire, and bring convenience to the use of the wire in different situations.
Description
Affiliated technical field
The utility model relates to a kind of wire rod of linear configuration, and its flexural rigidity can be adjusted.
Background technique
At present, known wire rod is joined by the multiply strip material with certain sectional shape and is formed, and some is made of sub-thread strip material, and after the production moulding, under constant condition such as ambient temperature, its flexural rigidity immobilizes.To some applications that needs often to adjust flexural rigidity, be difficult to meet the demands.
Summary of the invention
In order to overcome the deficiency that existing wire rod is difficult to adjust easily flexural rigidity, the utility model provides a kind of wire rod, and this wire rod not only has the characteristic of traditional wire rod, and can regulate flexural rigidity easily.
The technological scheme that its technical problem that solves the utility model adopts is: the vertically default some distending grooves in edge on wire rod, distending groove corner angle staff is vertical perpendicular to wire rod, embedded distending wedge, the distending wedge has threading hole, in wear silk rope, the silk rope is spirally wound on the wire rod, and an end is fixed in wire rod one end, and an end connects the tightener that is laid in the wire rod the other end.Tighten up silk when restricting to a certain degree, the silk rope tension makes the distending wedge closely contact with distending groove on the wire rod, and distending groove sidewall is produced pressure, and distending groove aperture increases, and wire rod produces certain prestressing force, and flexural rigidity changes thereupon.As long as be no more than the limit of elasticity of wire rod, just can regulate the prestressing force of wire rod easily by folding and unfolding silk rope, and then regulate its flexural rigidity.
The beneficial effects of the utility model are that the flexural rigidity of wire rod can be regulated, convenient multiple occasion use.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a schematic diagram of structure of the present utility model.
Fig. 2 is first embodiment's of the utility model a three-view diagram.
1. wire rods among the figure, 2. a rope, 3. distending groove, 4. distending wedge, 5. tightener.
Embodiment
In Fig. 1, wire rod (1) is gone up default distending groove (3), and silk rope (2) one ends are fixed on an end of wire rod (1), and spiral is wound on the wire rod (1), and passes the perforate on the distending wedge (4).When the on-fixed end tightened up silk rope (2), distending wedge (4) closely contacted with distending groove (3), and to distending groove (3) sidewall generation pressure, as shown in the figure.Wire rod (1) is out of shape under this pressure effect, produces prestressing force, and flexural rigidity changes thereupon.As long as be no more than the limit of elasticity of wire rod (1), by folding and unfolding silk rope (2), can regulate the prestressing force of wire rod (1) easily, and then regulate its flexural rigidity.Reverse for avoiding wire rod to produce, silk rope (2) preferably is provided with in pairs, and twines according to opposite direction, as shown in the figure.
In embodiment illustrated in fig. 2, tightener (5) is the assembly that screw rod, gear etc. are formed, equal power folding and unfolding two rhizoid ropes (2) of constant speed simultaneously, and two rhizoid ropes (2) symmetry in the other direction are wrapped on the wire rod (1), pass distending wedge (3) simultaneously.Operation tightener (5), the flexural rigidity that can regulate wire rod (1) easily.
Claims (3)
1. adjustable flexural rigidity wire rod, on wire rod, lay distending groove, silk rope, distending wedge formation, it is characterized in that: default distending groove on the wire rod, distending groove corner angle staff is vertical perpendicular to wire rod, the distending wedge places the distending groove, regulate it and make wire rod produce prestressing force, and then regulate bending wire rigidity distending groove lateral wall pressure.
2. adjustable flexural rigidity wire rod according to claim 1 is characterized in that: silk rope spiral is wound in wire rod, and passes the distending wedge, and an end is fixed in wire rod one end, and the other end connects the tightener of the wire rod the other end.
3. adjustable flexural rigidity wire rod according to claim 1 is characterized in that the silk rope uses in pairs, twines according to the opposite direction spiral.
