Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of underwear, more particularly to a flexible steel ring and a setting mold. BACKGROUND

[0002] With the increasing of material life level, the modern women who love beauty, in order to prevent breast ptosis, ensure the plumpness of chest, or show perfect chest type, the requirements of bra are also higher and higher. The existing bra, body shaping clothes and other women's underwear are mainly made of cloth, and the characteristics of cloth make wearing comfortable, and in order to better improve the support of underwear to the breast, the arc-shaped steel ring is usually arranged on the lower edge of the cup of the underwear. There is a difficult contradiction in the rigidity (hardness) of the arc-shaped steel ring: if a steel ring with high rigidity is used, although it has higher supporting force and better shaping effect, its softness is poor, and when the underwear is worn, the steel ring will form a steel ring indentation around the breast, reducing the comfort of the user; if a steel ring with low rigidity is used, although the steel ring is more flexible and the wearing comfort is better, the steel ring is prone to deformation and distortion after a long time of use, thereby making the underwear not fit the body and reducing the wearing comfort. Especially in the washing process, the steel ring is prone to deformation. In the prior art, the arc-shaped steel ring often uses a single steel ring structure, and various cross-section designs are used to strive to balance the support and flexibility, but the effect is different. In addition, although the existing arc-shaped steel ring is covered with cloth pipe or velvet, the two ends of the steel ring are easily pierced through the cloth pipe or velvet under extreme extrusion, which can stab the user, and the use is not safe.

[0038] a coating layer 300, which is coated on the surface of the stainless steel wire rope 100.

[0039] The diameter of the steel wire 110 is 0.01-0.15 mm, and the diameter of the stainless steel wire rope 100 is 1.8 mm. The above-mentioned restrictions on the diameter of the steel wire 110 and the diameter of the stainless steel wire rope 100 are both conducive to the flexible steel ring achieving a suitable modulus, taking into account the support strength and the flexible and comfortable characteristics.

[0040] To ensure safety in use, the flexible steel ring further comprises an end sleeve 200, which can prevent the flexible steel ring from piercing through the bra; and a coating layer 300, which provides further safety protection and enhances the flexibility and comfort of the flexible steel ring.

[0041] The material of the end sleeve and / or the coating layer is one or more of silicone, heat-shrinkable material, webbing, PU injection molding glue, PET, or nylon powder coated glue. Silicone can add flexibility and comfort; heat-shrinkable material can closely adhere to the stainless steel wire rope, enhancing the protection effect; webbing is fashionable and beautiful, enhancing the grip; PU injection molding stainless steel wire rope makes the touch unique, soft and soft like cotton under light pressure, and hardens instantly for protection upon impact, combining safety and comfort; PET / nylon powder coated glue has the advantages of wear resistance and tear resistance, and the design of the coated glue can improve the hand feeling and prolong the service life.

[0042] The flexible steel ring provided in the embodiment realizes a major breakthrough in the performance of the steel ring material. The stainless steel wire rope 100 is twisted from the steel wire 110, so that the flexible steel ring has high modulus rigidity and low modulus flexibility, taking into account the support requirements and comfort requirements of the bra. Compared with traditional steel rings, the flexible steel ring is flexible and not easy to break, and can be adjusted at will according to the requirements, suitable for various changes in chest shape, and has no feeling of restraint. More importantly, the unique structural design of the flexible steel ring allows 360-degree free rolling without deformation, ensuring long-lasting durability of the product.

[0043] In order to further improve the comfort, as shown in Figure 3 The central angle of the arc of the stainless steel wire rope 100 is less than 180°, and the included angle a of the tangent lines of the two end points is 40°-50°. The central angle of the arc is less than 180°, i.e. the two ends of the arc are open outward. The distance between the two end points of the stainless steel wire rope 100 is 110-140 mm. The above-mentioned angle and size restrictions make the flexible steel ring more fit the curve of the female breast, further improving the comfort.

The above structure makes the L-shaped plate 550 detachable, and in use, the distance between the L-shaped plate 550 and the shaping plate 500 is adjusted to facilitate the putting and taking of the stainless steel wire rope 100 into and out of the shaping mold, and the adjustment of the compression degree of the stainless steel wire rope 100.

[0057] Embodiment 4

[0058] The difference between the present embodiment and Embodiment 3 is that the second pressing plate 700 is replaced by a pressing block (not shown in the figure).

[0059] The pressing block is provided with a through hole, and the upper bottom surface of the shaping plate 500 is provided with a screw hole 521 corresponding to the position of the through hole, and the pressing block is connected with the shaping plate 500 by a screw passing through the through hole.
