[0031] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0032] Based on this, it is possible to improve the situation in related technologies where, after a certificate has been stored for a long time, its inner pages will stick to the outer casing. In this case, the printed words are easily imprinted on the outer casing, affecting the display effect of the inner pages of the certificate. At the same time, when they are separated after sticking together, the certificate is easily torn.

[0033] Please see Figures 1-5 A certificate for preventing adhesion includes a hard shell 1 and a hard shell 2. The hard shell 1 and the hard shell 2 are symmetrically arranged and are rotatably connected to each other. A locking assembly 3 is provided on the side of the hard shell 2 away from the hard shell 1. The hard shell 2 fixes the hard shell 1 through the locking assembly 3. An internal fixing assembly 7 is provided inside the hard shell 1. An isolation strip 4 is installed at the edge of the hard shell 2, and the top of the isolation strip 4 abuts against the outer end of the hard shell 1. The hard shell 2 is separated from the hard shell 1 by the isolation strip 4, leaving a gap. Fixing straps 5 are fixedly installed at the four corners of the outer end of the hard shell 2.

[0034] The device in this solution is mainly used to preserve certificates. Unlike traditional certificate cases, it prevents the inner pages from getting damp and sticking together even after long-term storage. The fixing straps 5 at the four corners of the second hard case 2 are mainly used to secure the inner pages. The main body materials of the first hard case 1 and the second hard case 2 are the same; the difference lies in the internal fixing component 7 of the first hard case 1. The first hard case 1 and the second hard case 2 are rotatably connected together, allowing them to be combined. The internal fixing component 7 inside the first hard case 1 is mainly used to install the movable shell 6 and also increases the strength of the first hard case 1. This is because when the certificate is opened... The main feature is the unfolding of the hard shell 1. Therefore, by strengthening the structure of the hard shell 1, its service life can be improved. The locking assembly 3 is installed on the hard shell 2. The locking assembly 3 is mainly used to fix and limit the hard shell 1 when it is closed. When the hard shell 1 is magnetically attracted to the magnet 33 on the fixing block 31 by the metal block 15 inside, the outer side of the hard shell 1 will press the inclined surface on the limiting block 35, causing it to slide inward. When the limiting block 35 is reset, it can lock the hard shell 1, so that the hard shell 1 and the hard shell 2 can be locked more tightly, and it is not easy to open even if it is accidentally dropped, thereby improving the protection of the inner pages of the certificate.

[0035] An isolation strip 4 is installed on the outer edge of the hard cover 2. The isolation strip 4 can be glued to the edge of the hard cover 2. The isolation strip 4 surrounds the hard cover 2. The isolation strip 4 is made of rubber and has a certain degree of elasticity, which can increase the sealing when the hard cover 1 is closed on the hard cover 2. At the same time, the isolation strip 4 has a certain thickness. When the hard cover 1 is closed on the hard cover 2, the isolation strip 4 will prevent the hard cover 1 from contacting the inner pages of the certificate. At the same time, the isolation strip 4 is made of rubber, which can also improve the internal sealing between the hard cover 1 and the hard cover 2. Therefore, the inner pages of the certificate are not easy to get damp and stick to the hard cover 1 after long-term storage.

[0036] Optionally, in some embodiments, please refer to Figure 4 The hard shell 1 is composed of a face layer 11, a filling layer 12, a core layer 13 and a back layer 14. The core layer 13 and the filling layer 12 are located between the face layer 11 and the back layer 14. The face layer 11 is made of leather and the filling layer 12 is made of sponge.

[0037] The core layer 13 is made of gray cardboard, and the back layer 14 is made of cardboard. The outer ends of the face layer 11, filling layer 12, core layer 13 and back layer 14 are provided with notches 16 that are compatible with the locking assembly 3. A metal block 15 is fixedly installed between the filling layer 12 and the core layer 13.

[0038] The hard shell 1 in this solution mainly consists of four layers: a surface layer 11, a filling layer 12, a core layer 13, and a back layer 14. The inner solid component 7 is located between the filling layer 12 and the core layer 13. The surface layer 11 is the outermost layer, and the back layer 14 is located on the inner side. The filling layer 12 and the core layer 13 are located between the surface layer 11 and the back layer 14. The surface layer 11 is made of leather, which effectively protects the certificate from dirt, moisture, and daily wear and tear, extending the certificate's lifespan. The filling layer 12 is made of sponge, providing additional protection and reducing the impact and pressure on the certificate. The impact of the object is effectively prevented from being damaged by collision, while the core layer 13 is made of gray cardboard, which can improve the overall weight and strength and improve the stability of the structure. The innermost layer is made of cardboard with a smooth surface, which improves the texture. At the same time, notches 16 are opened on all four layers of the hard shell 1, and notches 16 are also set on the hard shell 2 for installing the locking assembly 3. The notches 16 on the hard shell 1 are used to cooperate with the locking assembly 3. A metal block 15 is fixed between the filling layer 12 and the core layer 13. The metal block 15 is mainly used to cooperate with the locking assembly 3.

[0039] Optionally, in some embodiments, please refer to Figure 2 and Figure 3 The locking assembly 3 includes a fixing block 31, which is fixedly installed on the outer end of the hard shell 2. An installation block 32 is fixedly connected to the outer end of the fixing block 31. Two magnets 33 are fixedly installed on the top of the fixing block 31, and the magnets 33 are magnetically connected to the metal block 15.

[0040] The locking assembly 3 also includes a limiting block 35. The mounting block 32 has a sliding groove 34 that is adapted to the limiting block 35. The limiting block 35 is slidably connected to the inner wall of the sliding groove 34. The sliding groove 34 has two telescopic springs 36 inside. One end of the telescopic spring 36 is fixedly connected to the outer end of the limiting block 35. The top of the limiting block 35 has an inclined surface that abuts against the outer end of the hard shell 1.

[0041] The locking assembly 3 in this design is mainly used to make the connection between the first hard shell 1 and the second hard shell 2 tighter, thereby improving the sealing performance of the isolation strip 4 and preventing internal moisture. The fixing block 31 is fixed to the notch 16 of the second hard shell 2, and the top of the fixing block 31 is fixed to the mounting block 32. The mounting block 32 has a sliding groove 34 inside, and the limiting block 35 is slidably connected inside the sliding groove 34. At the same time, two telescopic springs 36 are set inside the sliding groove 34, and the telescopic springs 36 are fixedly connected to the limiting block 35. The top of the limiting block 35 is provided with a slope, which is mainly used to abut against the first hard shell 1. Two magnets 33 are fixed on the mounting block 32. The magnets 33 can be connected to the metal block 1 fixed between the filling layer 12 and the core layer 13. 5. Through magnetic attraction, when hard shell 1 is placed on hard shell 2, the attraction force of magnet 33 will cause hard shell 1 to close downwards. At this time, the notch 16 on hard shell 1 will rest on the inclined surface of the limiting block 35. The attraction force will cause hard shell 1 to continue to move downwards. Then, by abutting against the inclined surface, the limiting block 35 can be pressed inwards. After hard shell 1 passes the limiting block 35, the force of the telescopic spring 36 will cause the limiting block 35 to return to its original position. At this time, by abutting against the bottom plane of the limiting block 35 with hard shell 1, hard shell 1 and hard shell 2 will be tightly closed together. This not only increases the sealing performance, but also makes it difficult to open if the certificate is accidentally dropped. When it needs to be opened, simply push the limiting block 35 inwards with your finger.

[0042] Optionally, in some embodiments, please refer to Figure 4 and Figure 5 The inner solid component 7 includes a bending plate 71, which is made of plastic and is fixedly installed between the filling layer 12 and the core layer 13. The outer end of the bending plate 71 has multiple through holes 72 that are evenly distributed, and multiple metal strips 73 are fixedly installed on the outer end of the bending plate 71.

[0043] Multiple metal strips 73 are distributed in an interlaced pattern. A movable shell 6 is provided at the outer end of the hard shell 1. A magnet is installed at the outer end of the movable shell 6. The movable shell 6 is connected to the metal strips 73 through the magnet.

[0044] The internal solid component 7 in this solution mainly consists of an anti-bending plate 71 and multiple metal strips 73. The anti-bending plate 71 is made of plastic and has multiple through holes 72 arranged in a matrix. The through holes 72 are mainly used for weight reduction. The multiple metal strips 73 are arranged in a perpendicular pattern and are made of metal. The matrix of multiple metal strips 73 is fixed to the outer end of the anti-bending plate 71. A movable shell 6 is also provided inside the hard shell 1. A magnet is fixed to the back of the movable shell 6. Through the magnetism between the magnet and the metal strips 73, the movable shell 6 can be detachably installed on the hard shell 1. At the same time, the movable shell 6 can be adjusted at will. The outer side of the movable shell 6 is concave. Since most certificates have ID photos, which are printed and pasted on, the ID photos are more prone to fading or deformation due to moisture. Therefore, by covering the ID photos with the movable shell 6, additional protection can be formed. Since the movable shell 6 is detachable, it can also be removed when not in use.

[0045] Working principle: When using this device, the inner pages of the certificate must first be installed on the hard shell 2 using the fixing strap 5. Then, the hard shell 1 can be placed on the hard shell 2. Due to the barrier of the isolation strip 4, the hard shell 1 will not come into contact with the inner pages of the certificate. At the same time, the isolation strip 4 is made of rubber, which can also improve the internal sealing between the hard shell 1 and the hard shell 2. It is not easy to get damp and stick to the hard shell 1 after long-term storage. At this time, the hard shell 1 will rest on the inclined surface of the limiting block 35. The suction force will make the hard shell 1 move downward. By abutting against the inclined surface, the limiting block 35 will be squeezed inward. The force of the telescopic spring 36 will make the limiting block 35 return to its original position, so that the hard shell 1 and the hard shell 2 are tightly closed together, which can increase the sealing.
