Description

Technical Field

[0001] This utility model relates to the field of negative ion technology, and in particular to a spring hinge for an eye ion pulse therapy device. Background Technology

[0002] An eye ion pulse therapy device developed for specific groups such as teenagers aims to relieve their eye strain. However, the high-voltage wire inside the product is repeatedly bent at the junction of the frame and temple, making it highly susceptible to breakage. Although the temples and frame can accommodate the wire passage through openings, this poses a serious threat to the product's safety and reliability. Utility Model Content

[0003] The purpose of this invention is to provide a spring hinge for an eye ion pulse therapy device, which can prevent the high-voltage wire from breaking during repeated bending of the temple of the glasses, thereby improving the safety and reliability of the eye ion pulse therapy device.

[0004] To solve the above-mentioned technical problems, the present invention provides a spring hinge for an eye ion pulse therapy device. The spring hinge includes a base, on which a hinge body is mounted. The hinge body is mounted with a rotating plate and a limiting cover plate via a rotating shaft. A spring is provided at the side ear of the T-shaped part of the hinge body, and a spring cover plate fixed to the base is provided at the spring mounting position of the hinge body.

[0005] Furthermore, the hinge body has a hinge back plate structure consisting of a straight hinge back plate and an adjacent curved hinge back plate. The hinge back plate structure has parallel-distributed hinge top and bottom plates, each with a pivot hole for mounting a pivot. The straight hinge back plate has parallel channel constraint blocks, each with a T-shaped section. The T-shaped section has T-shaped back grooves with openings in opposite directions to the hinge body. The lower base plate of the limiting cover is mounted on the hinge base plate via a pivot. The limiting cover forms a limiting groove using two curved pieces of different lengths. The upper base plate of the rotating piece is mounted on the hinge top plate via a pivot. The inner wall formed by the straight hinge back plate and the curved hinge back plate can serve as a sliding guide wall for the fan-shaped side plate of the rotating piece.

[0006] Furthermore, the bottom plate of the limiting cover is a circular plate with a pivot hole. The edge of the circular plate is provided with fan-shaped protrusions that are not distributed throughout the entire surface. One of the inner arc-shaped pieces of different lengths is installed on the edge of the circular plate. An extension block is provided at one end of the inner arc-shaped piece. On the extension block, there are outer arc-shaped pieces with a length shorter than the inner arc-shaped piece. The height of the outer arc-shaped pieces is greater than the height of the inner arc-shaped pieces. A locking block is provided on the outer arc-shaped piece. The height of the locking block is greater than that of the outer arc-shaped piece.

[0007] Furthermore, the upper base plate of the rotating plate is a circular plate with a pivot hole, and the edge of the upper base plate is provided with a fan-shaped side plate close to the hinge back plate structure and a spoon-shaped arc plate with a straight plate.

[0008] Furthermore, the base has a base back, and the base back is provided with vertical constraint blocks distributed one above the other. There is a T-shaped part assembly groove between the vertical constraint blocks. Spring constraint mounting grooves are symmetrically distributed on the vertical constraint blocks. The T-shaped ear of the T-shaped part of the hinge body is located in the spring constraint mounting groove, and one end of the spring abuts against the spring constraint mounting groove and the other end abuts against the T-shaped ear.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. This hinge combines the advantages of spring hinges, giving the temples greater elasticity, allowing for a wider opening angle, and increasing wearing fit and comfort.

[0010] 2. The rotating piece in the hinge is equipped with a limiter. The limiter can be located in the corresponding groove of the temple, so that the rotating piece rotates at the same time when the temple is opened and closed, ensuring that there is a large enough opening space to pass through a thicker wire harness, and that the wire harness is not exposed.

[0011] 3. The limiting cover plate can limit the bending angle of the temple when the rotating lens is bent.

[0012] 4. This spring hinge ensures that the high-voltage wires, which are relatively thick, do not repeatedly bend or break in the application scenarios of eye ion pulse therapy devices, thereby improving the safety and reliability of the eye ion pulse therapy devices. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] This utility model provides a spring hinge for an eye ion pulse therapy device, see [link to relevant documentation]. Figure 1 The spring hinge includes a base 4, a hinge body 5, a rotating plate 6, a limiting cover plate 7, a pivot 8, a spring 9, and a spring cover plate 10. This spring hinge is installed on a youth eye treatment device, which is a type of eyeglass carrier. The spring hinge is installed at the bend between the frame and the temple.

[0026] See Figure 2 The hinge body 5 is mounted on the base. A 2.8mm diameter high-voltage wire harness enters the spring hinge from one end of the base and extends into the hinge body, finally exiting through the outlet of the hinge body. The hinge body is equipped with a rotating plate 6 and a limiting cover plate 7 via a pivot 8. A spring 9 is provided at the side lug of the T-shaped part of the hinge body. A spring cover plate 10, fixed to the base, is provided at the spring mounting position of the hinge body. Figure 11 It can be seen that there is a square plate structure 11a and cross-shaped protrusions 11b distributed on the square plate structure. The upper wing 11b-1 and lower wing 11b-2 of the cross-shaped protrusions can cover the spring constraint mounting groove of the base, thereby constraining the spring within the spring constraint mounting groove. In addition to the screw holes for fixing it to the base, the spring cover plate also has screw holes P1 for fixing the base of the spring hinge to the inner frame of the mirror frame.

[0027] Combination Figure 3 and Figure 4It is known that the hinge body 5 has a hinge back plate structure consisting of a hinge straight back plate portion 5a and a hinge arc-shaped back plate portion 5b adjacent to the hinge straight back plate portion. The hinge back plate structure is provided with a hinge top plate 5c and a hinge bottom plate 5d distributed in parallel. The hinge top plate and hinge bottom plate are provided with pivot holes for mounting pivots. The hinge straight back plate portion is provided with mutually parallel channel constraint blocks 5e. The channel constraint blocks are provided with screw holes for fixing the limiting cover plate. Correspondingly, there are two matching screw holes distributed at the locking block of the limiting cover plate, so that the limiting cover plate is fixed to the channel constraint block by screws. The channel constraint block is provided with a T-shaped portion 5f. The T-shaped portion is provided with a T-shaped back groove 5f-1 with the opening direction opposite to that of the hinge body. The gap between the T-shaped back groove and the channel constraint block is connected, so that the high-voltage wire harness inside the T-shaped back groove can enter the interior of the hinge body (see Figure 5 The space between the hinge top plate and the hinge bottom plate, guided and constrained by the limiting cover plate 7 and the rotating piece 6, can form a wire harness passage between the T-shaped back groove and the base 4. The lower bottom plate of the limiting cover plate 7 is mounted on the hinge bottom plate via a pivot. The limiting cover plate forms a limiting groove 7c through two arc-shaped pieces of different lengths. The two arc-shaped pieces of different lengths are respectively defined as the inner arc-shaped piece 7a and the outer arc-shaped piece 7b. The upper bottom plate of the rotating piece 6 is mounted on the hinge top plate via a pivot.

[0028] See Figure 6 The lower base plate of the limiting cover 7 is a circular plate with a pivot hole. The edge of this circular plate has non-uniformly distributed fan-shaped protrusions 7d. The upper surface of these protrusions 7d serves as the sliding track for the fan-shaped side plate 6a of the rotating plate (its outer side is constrained by the inner wall of the hinge back plate structure). Figure 5 It can be seen that the fan-shaped protrusion 7d extends and is installed at the high-voltage harness outlet of the hinge back plate structure. One of the inner arc-shaped pieces 7a, of different lengths, is installed on the edge of the circular plate. The arc length of the inner arc-shaped piece is greater than that of the outer arc-shaped piece. The gap between the misaligned inner and outer arc-shaped pieces is... Figure 5 It can be seen that the arc-shaped part of the spoon-shaped arc plate 6b can be pushed into the gap. When the temple of the eyeglasses is folded, the spoon-shaped part of the spoon-shaped arc plate can protect the high voltage wire harness from deflection. An extension block is provided at one end of the inner arc plate. An outer arc plate 7b with a length less than that of the inner arc plate is distributed on the extension block. The height of the outer arc plate is greater than that of the inner arc plate. A locking block 7e is provided on the outer arc plate. The height of the locking block is greater than that of the outer arc plate.

[0029] See Figure 7 and Figure 8The upper base plate of the rotating plate is a circular plate with a pivot hole. The edge of the upper base plate is provided with a fan-shaped side plate 6a near the hinge back plate structure and a spoon-shaped arc plate 6b with a straight plate. When the rotating plate can be rotated in a controllable manner, it can provide better protection for the high-voltage wire harness and avoid the high-voltage wire harness bending and other situations.

[0030] See Figure 9 The base has a base back 4a, and a vertical constraint block 4b is provided on the base back. The vertical constraint block is connected by a T-shaped part assembly groove 4d. Spring constraint mounting grooves 4c are symmetrically distributed on the vertical constraint block. The T-shaped ear of the T-shaped part of the hinge body is located in the spring constraint mounting groove, and one end of the spring abuts against the spring constraint mounting groove and the other end abuts against the T-shaped ear 5f-2.

[0031] Because a high-voltage wire is arranged between the frame and the eyeglasses at the eye end, a 2.8mm diameter wire harness must pass through between them. Traditional hinges can pass through the wire but cannot fold, or while there are foldable hinges, they can only pass through the thin wire harness and lack a spring structure, thus limiting the opening angle of the temples. Therefore, this invention incorporates a spring hinge between the frame and the eyeglasses at the eye end. See [link to relevant documentation]. Figure 1 The spring hinge includes a base 4, on which a hinge body 5 is mounted. The hinge body is equipped with a rotating piece 6 and a limiting cover plate 7 via a pivot 8. A spring 9 is located at the side lug of the T-shaped portion of the hinge body, and a spring cover plate 10, fixed to the base, is located at the spring mounting position on the hinge body. This hinge combines the advantages of a spring hinge, giving the temples greater elasticity, accommodating a wider opening angle, and increasing wearing fit and comfort. The rotating piece in the hinge has a limiting feature, which can be positioned within a corresponding groove on the temple, ensuring that the rotating piece rotates simultaneously when the temple is opened and closed, guaranteeing a sufficiently large opening space to allow thicker wires to pass through without any exposed wires. The limiting cover plate prevents the rotating piece from bending the temple at an excessively large angle.

[0032] When the temples open or bend, there is interference between the temple shell and the frame shell. At this time, the hinge body will compress the spring, allowing the temple to rotate with sufficient space. Once it has rotated to a certain angle and the temple no longer interferes with the frame, the hinge body is pushed back to its original position by the spring. When the temples open to an excessive angle, interference occurs between the temples and the frame. The hinge body can also compress the spring to allow the temples to open to an additional angle.

[0033] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
