Detailed Description
For the understanding of those skilled in the art, the present invention will be further described with reference to the following examples and accompanying fig. 1-2, which are not intended to limit the present invention.
Referring to fig. 1-2, the light high-elasticity spring is formed by winding a metal wire and comprises a spring body, wherein the spring body comprises a first elastic section 11, a flexible section 12 and a second elastic section 13 which are sequentially connected from top to bottom, the longitudinal sections of the metal wires of the first elastic section 11 and the second elastic section 13 are both circular, and the longitudinal section of the metal wire of the flexible section 12 is oval; the metal wire of the flexible section 12 is wound at least two times, and the metal wires of the first elastic section 11 and the second elastic section 13 are wound at least two times; the metal wire is a steel wire.
The light high-elasticity spring in the embodiment is simple and novel in structure, a three-section structure is adopted, the longitudinal sections of the metal wires of the first elastic section 11 and the second elastic section 13 are controlled to be circular, and the longitudinal section of the metal wire of the flexible section 12 is controlled to be oval, so that better elasticity, support property and softness can be realized; when the spring is used, the first elastic section 11 which is firstly contacted provides soft supporting touch feeling for a user, and the flexible section 12 provides powerful buffering supporting force for the user along with the compression of the spring body, so that the user can feel soft and hard feeling of the spring at the same time, and the spring has variable hardness, layering feeling and high comfort level.
In this embodiment, the extending direction of the minor axis of the ellipse is perpendicular to the compressing direction of the spring, and the extending direction of the major axis of the ellipse is the same as the compressing direction of the spring; the ratio of the length of the minor axis to the length of the major axis of the ellipse is 1.7-1.9: 2.3-2.6; the diameters of the metal wires of the first elastic section 11 and the second elastic section 13 are both 2.0-2.4 mm.
The oval minor axis of longitudinal section and the extending direction and the size proportion of major axis through the control flexible section 12 wire in this embodiment can promote the rigidity of spring under the unchangeable condition of spring pitch, number of turns, spiral diameter, and the longitudinal section is oval-shaped wire can not increase the volume of spring simultaneously, and is comparatively light on the contrary, and the elasticity effect is better.
In this embodiment, the ratio of the pitch of the first elastic segment 11 and the pitch of the second elastic segment 13 to the pitch of the flexible segment 12 is 1: 1.3-1.6; the thread pitch of the flexible section 12 is 5-8 cm.
In the embodiment, the screw pitches of the sections are controlled to enable stress surfaces at two ends of the three-section spring to be larger, so that the quantity is saved and the supporting effect is ensured when the light high-elasticity springs are assembled side by side, and the hard spring is prevented from being damaged due to instant stress when the spring body is compressed under stress.
In this embodiment, the spiral diameter of the flexible segment 12 is larger than the spiral diameter of the first elastic segment 11 and the spiral diameter of the second elastic segment 13; the spiral diameter of the flexible section 12 is 5-6 cm.
In this embodiment, the upper end surface of the first elastic section 11 is the surface closest to the body of the consumer, and the diameter of the spiral of the first elastic section 11 is controlled to be smaller than that of the spiral of the flexible section 12, so that the touch feeling of the human body to the upper end surface of the spring can be reduced, and the skin-friendly degree of the mattress can be effectively improved.
The above-described embodiments are preferred implementations of the present invention, and the present invention may be implemented in other ways without departing from the spirit of the present invention.
