Description

Technical Field

[0001] This utility model belongs to the field of photo album structure technology, specifically relating to a portable three-layer photo paper photo album structure. Background Technology

[0002] Traditional photo albums often use a single-layer or simple binding structure, which results in problems such as inconvenience in carrying, easy delamination of inner pages, and poor resistance to bending. In current technology, album covers mostly rely on glued binding, which easily leads to separation and delamination over long-term use; inner pages are susceptible to moisture damage, causing the photo paper to warp. Furthermore, they lack a carrying handle, relying mostly on manual grips or external handles, affecting aesthetics and overall appearance.

[0003] To address the aforementioned shortcomings, a portable three-layer photo paper album structure is proposed to improve user experience and product lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a portable three-layer photo album structure that solves the problems of easy delamination, photo paper warping, and lack of carrying function in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a portable three-layer photo paper album structure, including a spine, with the cover and back cover connected to both sides of the spine respectively. Inner pages are connected to the inner wall of the spine by adhesive. A cover plate is provided on the outer side of the cover and back cover, and gold foil lettering is provided on the outer wall of the cover plate. The cover plate is fixed to the cover and back cover by stitching. A handle is provided in the center of the side wall of the cover and back cover. The handle is U-shaped and its outer end is fixed to the inner wall of the cover and back cover. The outer end of the handle is bent and attached to the outer wall of the cover and back cover.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, such as Figure 1 As shown, a portable three-layer photo paper album structure includes a spine 1, which serves as the central support structure of the album, connecting the cover 2 and the back cover 3 to enhance the overall bending resistance. The spine 1 is connected to the cover 2 and the back cover 3 on both sides, respectively. The cover 2 and the back cover 3 protect the inner pages 4, provide closure support, and are scratch-resistant and aesthetically pleasing.

[0021] The inner pages 4 are attached to the inner wall of the spine 1 via adhesive 5. The inner pages 4 hold photographic paper for easy display, and the adhesive 5 secures the inner pages 4 to the inner wall of the spine 1. A cover plate 6 is provided on the outer side of the cover 2 and back cover 3. The outer wall of the cover plate 6 is decorated with gold foil lettering 9, enhancing the album's texture and personalization. The cover plate 6 is secured to the cover 2 and back cover 3 by stitching 7. The stitching 7 mechanically fixes the cover plate 6 to the cover 2 and back cover 3. The high-strength nylon thread is wear-resistant and tensile-resistant, more durable than traditional stitching 7, and will not unravel over long-term use. The cover plate 6 covers the outer side of the cover 2 and back cover 3, providing both decoration and protection.

[0022] Handles 8 are provided at the center of the side walls of the cover 2 and the bottom cover 3. The outer end of the handle 8 is U-shaped and fixed to the inner wall of the cover 2 and the bottom cover 3. The outer end of the handle 8 is bent and attached to the outer wall of the cover 2 and the bottom cover 3. The handle 8 realizes the function of convenient carrying, maintains a simple appearance, and has strong lifting and load-bearing capacity.

[0023] The specific design of the aforementioned key components will be discussed in detail below:

[0024] The inner page 4 has a three-layer structure consisting of a middle cardboard and two layers of photo paper. The middle cardboard is made of rigid cardboard with a thickness of 1.5-2mm to provide support and prevent the photo paper from bending. The photo paper on both sides is covered with a matte or glossy film with a thickness of 0.2-0.3mm, which is adhered to the sides of the cardboard to form a sandwich layer.

[0025] The inner page 4 is a one-piece molded structure. The middle cardboard and the photo paper on both sides are fixed by a hot-pressing composite process. The hot-pressing composite process (temperature 120-150℃, pressure 5-8MPa) is used to bond the cardboard and photo paper together, ensuring no air bubbles and no delamination. After the cardboard and photo paper are stacked, they are pressed at high temperature for 10-15 seconds and pressure 6MPa. After cooling and shaping, the edges are trimmed.

[0026] A magnetic block is provided inside the handle 8, and iron sheets are provided inside the cover 2 and the bottom cover 3 at the corresponding positions of the magnetic block. The magnetic block is embedded inside the U-shaped handle 8, and the galvanized iron sheet is embedded in the corresponding position on the outer wall of the cover plate 6. The magnetic closure does not require manual alignment, and the adsorption force is stable after closure. The hidden design ensures that the magnetic block and the iron sheet are completely attached when closed, with no protrusions on the surface.

[0027] The top and bottom walls of the inner pages 4 are connected by a butterfly binding structure. Specifically, the top and bottom walls of adjacent inner pages 4 are seamlessly connected by folded cardboard with a width of 5-8mm. The folds have a V-groove with a pre-pressed depth of 0.5mm. The inner pages 4 are connected to each other without glue and rely on the folded cardboard for support.

[0028] The cover plate 6 is made of rigid cardboard. The outer layer of the cover 2, cover plate 6, and back cover 3 is covered with wear-resistant PU leather. The stitching 7 is made of high-strength nylon thread, and the adhesive 5 is weather-resistant hot melt adhesive. The edges of the rigid gray cardboard are beveled by 0.5mm and then coated with a waterproof polyurethane coating. The outer layer of the cover 2, back cover 3, and cover plate 6 is bonded with wear-resistant PU leather. The stitching 7 is made of double-strand high-strength nylon thread with a spacing of 3-5mm. The adhesive 5 is weather-resistant hot melt adhesive applied to the inner wall of the spine 1. The rigid cardboard + PU leather is pressure-resistant and wear-resistant, the waterproof coating is splash-proof, and the double fixation of nylon thread and hot melt adhesive improves the structural lifespan.

[0029] The edge of the cover plate 6 is covered with a waterproof coating, and the connection between the cover 2, the bottom cover 3, and the spine 1 adopts a rounded transition structure. The connection between the cover 2, the bottom cover 3, and the spine 1 adopts an R5-R8mm rounded transition, and the inner and outer layers of PU leather are integrated to eliminate right-angle edges, making it comfortable to hold and preventing fabric wear.
