Description

Technical Field

[0001] The invention relates to a wristband, in particular to a double-fulcrum wristband. Background Art

[0002] In the prior art, wristbands are a commonly used wearable device, widely used for identification and information management of patients, newborns and other groups. Traditional wristbands usually adopt an open design, with both ends closed by means of buckles or latches to adapt to the wrist or ankle sizes of different wearers. However, this design has significant limitations, mainly in terms of wearing comfort and adjustment accuracy.

[0003] The traditional wristband adjustment method usually has a series of buckle holes on one end of the band and a buckle on the other end. When worn, the buckle is buckled into the corresponding buckle hole to adapt to the outer diameter of the wrist or ankle. Although this belt-like buckling method has a certain degree of adjustability, due to the fixed spacing limit between the buckle holes, there is a gap in the aperture adjustment of the wristband. This gap will cause the adjusted wristband to be either too loose or too tight when worn, and it is impossible to achieve a precise fit, especially when worn by newborns. The problem is particularly prominent. A wristband that is too loose is easy to fall off, making it difficult to confirm information and inconvenient to wear repeatedly; a wristband that is too tight may cause discomfort to the wearer or even potential blood circulation disorders, seriously affecting the wearing experience and safety.

[0004] In addition, existing wristbands are usually one-piece structures, and the band body has a certain width. In the actual wearing process, due to the inconsistency of the outer diameters of various parts of the wrist or ankle, even if the wristband is adjusted to a suitable tightness, the local part will still be uncomfortable due to size mismatch, or there will be a risk of loosening during activities. The prior art has not yet provided a wristband structure that can achieve stepless adjustment at different wearing parts, meet local fitting requirements, and ensure wearing stability and comfort at the same time, especially for newborns and patients who have higher requirements for wearing comfort and stability. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a double-fulcrum wristband, which can realize segmented adjustment of the double-fulcrum wristband structure at different positions of the wrist or ankle. By setting at least two inner support rings and introducing elastically adjustable adjustment fulcrums, it can meet the outer diameter requirements of different wearing positions and achieve precise fitting when worn. At the same time, it has the characteristic of stepless adjustment. The wristband not only greatly improves the comfort and stability, but also effectively reduces the risk of falling off. It is particularly suitable for specific groups of people who have high requirements for wearing effects, such as newborns and patients.

[0006] The present invention is realized by the following technical scheme: a double-pivot wristband, comprising: An outer ring, wherein the outer circumferential surface of the outer ring is an information display surface; At least two inner support rings are mounted on the inner circumference of the outer ring, and each inner support ring is detachably connected to the inner circumference of the outer ring via one or more adjustment fulcrums; At least two inner support rings form at least two annular wearing fulcrums with different inner diameters in the axial direction.

[0007] As a preferred technical solution, at least two inner support rings are arranged on both sides of the inner circular surface of the outer ring, and the adjustment fulcrum is fixedly arranged on the inner circular surface of the outer ring and is arranged around the inner circular surface of the outer ring.

[0008] As a preferred technical solution, the adjustment fulcrum includes an adjustment clip with elastic deformation capability, one end of the adjustment clip is fixedly connected to the inner circular surface of the outer ring, and an adjustment clamping cavity is formed in the middle of the adjustment clip; A penetrating arc-shaped air-avoiding groove is provided on the inner support ring corresponding to each adjusting clip. The inner support ring at the position of the arc-shaped air-avoiding groove is protruded toward the adjusting clamping cavity to form an adjusting convex portion. Each adjusting convex portion is buckled into the adjusting clamping cavity and fixed by the adjusting clip.

[0009] As a preferred technical solution, a protruding adhesive portion is provided on each side of the adjustment clamping cavity relative to the position of the arc-shaped air avoidance groove. When the adjustment protrusion is adjusted and buckled into the adjustment clamping cavity, the two adhesive portions pass through the arc-shaped air avoidance groove and then adhere to each other.

[0010] As a preferred technical solution, both sides of the adjustment protrusion are in contact with the adjustment clip to form an adhesive contact surface, and a slightly convex adhesive layer is provided on the side of the adjustment clip in contact with the adhesive contact surface. Release paper is provided on the outside of the adhesive layer. After tearing off the release paper, the adjustment clip is bonded to the adhesive contact surface on the adjustment protrusion through the adhesive layer.

[0011] As a preferred technical solution, the adjusting clip is made of elastic rubber material.

[0012] As a preferred technical solution, the at least two inner support rings include a first inner support ring and a second inner support ring, and the first inner support ring and the second inner support ring are arranged at intervals on both sides of the inner circular surface of the outer ring.

[0013] The beneficial effects of the present invention are as follows: the double-fulcrum wristband of the present invention is provided with at least two inner support rings on the inner circumferential surface of the outer ring, so that the wristband can form wearing fulcrums with different inner diameters along the axial direction when worn, so as to adapt to the change of the outer diameter of the wrist or ankle at different positions. The double-fulcrum structure can not only effectively disperse the wearing pressure, but also make the wristband fit more closely with the wearing part, and avoid looseness or discomfort caused by the difference of the outer diameter at different positions of the wrist or ankle, and is particularly suitable for the wearing needs of newborns and patients; At the same time, the present invention adopts an adjustment fulcrum connection structure between the outer ring and the inner support ring, each adjustment fulcrum is fixed to the inner circular surface of the outer ring through an adjustment clip with elastic deformation ability, and an adjustment clamping cavity is formed in the middle of the adjustment clip, through which the adjustment convex part of the inner support ring can be stably buckled and steplessly adjusted, so as to flexibly adjust the wearing aperture according to the requirements of different wearing positions. This stepless adjustment structure not only simplifies the wearing process, but also can realize fine adjustment from tightness to fit according to the change of the outer diameter of the wrist or ankle, avoiding the problem of too loose or too tight caused by the buckle hole spacing of the traditional wristband, so that the wearing comfort is significantly improved; More importantly, the present invention can limit the wearing aperture of the inner support ring and complete the connection between the inner support ring and the outer ring by adjusting the clip, so that the inner support ring is positioned on the inner circular surface of the outer ring, simplifying the overall structure and making the design more reasonable.

[0016] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0017] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0018] like Figure 1 and Figure 2 As shown, a double-pivot wristband of the present invention comprises an outer ring 1, the outer circumferential surface of the outer ring 1 is an information display surface, and basic information such as a QR code and a name can be printed thereon, and the outer ring 1 is made of ordinary material; In this embodiment, two inner support rings are included, which are installed on the inner circular surface of the outer ring 1. Each inner support ring is detachably connected to the inner circular surface of the outer ring 1 through more than one adjustment fulcrum. The inner support ring can be removed and installed relative to the outer ring 1. The structure of the two inner support rings is the most reasonable. They can be installed on both sides of the outer ring 1, one on the left and one on the right, as two-point support. Since they are two annular wearing points, one side is pulled and the other side can also be worn, so that the whole wristband has better anti-pulling ability, is less likely to loosen, and can meet the wearing stability; In this embodiment, the two inner support rings form at least two annular wearing fulcrums with different inner diameters in the axial direction. Since different positions of the wrist or ankle have different outer diameters, the two inner support rings can be manually adjusted when worn to have annular wearing fulcrums with different inner diameters, so as to fit the wearer in different position segments. Therefore, through the inner support rings, when the present invention is installed, the inner support rings are adjusted to the appropriate position points according to different positions to complete the wearing, which is more fitting and makes the wearer more comfortable and stable.

[0019] Specifically, the two inner support rings are arranged on both sides of the inner circular surface of the outer ring 1, the adjustment fulcrum is fixedly arranged on the inner circular surface of the outer ring 1, and is arranged around the inner circular surface of the outer ring 1. The side surfaces of the two inner support rings can protrude from both sides of the outer ring 1 and can be completely retracted into the outer circular surface of the outer ring 1.

[0020] Among them, Figure 3 As shown, the adjustment fulcrum includes an adjustment clip 4 with elastic deformation ability, one end of the adjustment clip 4 is fixedly connected to the inner circular surface of the outer ring 1, and an adjustment clamping cavity is formed in the middle of the adjustment clip 4. When wearing the wristband, it can be manually adjusted so that the inner support ring is partially buckled into the adjustment clamping cavity and clamped and fixed by the adjustment clip 4, so as to adjust the wearing inner diameter of the supporting inner ring; Specifically, an arc-shaped air-avoiding groove 6 is provided on the inner support ring corresponding to each adjusting clip 4, and the inner support ring at the position of the arc-shaped air-avoiding groove 6 is protruded toward the adjusting clamping cavity to form an adjusting convex portion 5, and each adjusting convex portion 5 is buckled into the adjusting clamping cavity, and the adjusting convex portion 5 is fixed by the adjusting clip 4. The protruding size of the adjusting convex portion 5 depends on the size of the wearer's wrist or ankle, and can be adjusted manually. Due to the stepless adjustment, the protruding value of the adjusting convex portion 5 can be arbitrarily controlled, so that the entire inner support ring can be better worn on the wrist.

[0021] Among them, Figure 4 and Figure 5 As shown, a protruding adhesive portion 7 is provided on each side of the position of the arc-shaped air avoidance groove 6 in the adjustment clamping cavity. When the adjustment protrusion 5 is adjusted and buckled into the adjustment clamping cavity, the two adhesive portions 7 pass through the arc-shaped air avoidance groove 6 and then adhere to each other. The adhesive portion 7 can be an elastic material, and an adhesive layer can be provided on its contact surface.

[0022] like Figure 3 and Figure 5 As shown, both sides of the adjusting protrusion 5 contact with the adjusting clip 4 to form an adhesive contact surface 100, and the adjusting clip 4 is provided with a slightly convex adhesive layer on the contact surface 100, and a release paper is provided on the outside of the adhesive layer. After tearing off the release paper, the adjusting protrusion 5 is bonded to the adhesive contact surface 100 on the adjusting protrusion 5 through the adhesive layer. The position where the adjusting protrusion 5 contacts the adjusting clip 4 is a common adhesive layer, which is mainly used to bond the contact position of the adjusting clip 4 and the inner support ring, and the adhesive portion 7 is used to limit the opening of the adjusting clip 4. Therefore, after the adjusting clip 4 is limited to open, as long as the protrusion value of the adjusting protrusion 5 is adjusted, the adjusting protrusion 5 is inserted into the adjusting clamping cavity, and then the adjusting protrusion 5 is bonded and limited in the adjusting clamping cavity by the adhesive layer. The adjusting clip 4 can have a certain elastic tension, which is sufficient to support and position the inner support ring. Specifically, the adjusting clip 4 is made of elastic rubber material.

[0023] like Figure 1 and Figure 5 As shown, the two inner support rings include a first inner support ring 2 and a second inner support ring 3. The first inner support ring 2 and the second inner support ring 3 are arranged at intervals on both sides of the inner circular surface of the outer ring 1. The first inner support ring 2 and the second inner support ring 3 can have different wearing inner diameters to meet the needs of fitting at different wearing positions.

[0024] The present invention can limit the wearing aperture of the inner support ring and complete the connection between the inner support ring and the outer ring 1 by adjusting the clip 4, so that the inner support ring is positioned on the inner circular surface of the outer ring 1, simplifying the overall structure and making the design more reasonable.

[0025] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
