Description

Technical Field

[0001] This utility model relates to a cover, specifically a cover for easy certificate replacement. Background Technology

[0002] A certificate sleeve is an item used to store and protect certificates. Currently, most certificate sleeves on the market use retaining strips at the four corners to secure the certificate. When placing the certificate, the four corners need to be inserted into the retaining strips one by one. When removing the certificate, it needs to be bent out from the four corners one by one. This process of removal and assembly is cumbersome, and bending the certificate may damage it. Furthermore, when the paper is tightly pressed against a flat surface, a relatively enclosed space is formed between the paper and the surface. If the paper is pressed quickly, air is squeezed out, causing a decrease in air pressure between the paper and the surface. The external atmospheric pressure then presses the paper against the surface, creating an adhesive effect. The edges of the certificate are tightly adhered to the surface without gaps, making it difficult for the user to remove the certificate. Therefore, those skilled in the art have provided a sleeve that allows for easy certificate replacement to solve the problems mentioned in the background art. Utility Model Content

[0003] To solve the above technical problems, this utility model provides an easy-to-replace certificate cover, including a cover and a bottom surface, with a connecting strap connecting the cover and the bottom surface. A limiting frame is fixedly connected to the inner side of the bottom surface, with an opening on the side of the limiting frame away from the cover and a slot inside the limiting frame. A limiting strip is fixedly connected to the side of the cover away from the bottom surface, and the limiting strip can be located at the opening of the limiting frame.

[0004] Multiple raised strips are fixedly connected inside the bottom surface between the limiting frames. The raised strips have a raised center and the height of the raised strips is lower than the height of the upper end of the limiting frames.

[0005] Preferably, the limiting frame has a bevel at one end and a bevel on one side of its bottom surface.

[0006] Preferably, the raised strip has multiple grooves.

[0007] Preferably, a magnetic block is embedded inside the inclined surface, and the limiting strip is made of iron and can fit against the inclined surface.

[0008] Preferably, a retrieval opening is provided on the inclined surface.

[0009] Preferably, the cover has an observation port, and the inside of the observation port is lined with transparent plastic.

[0010] Preferably, the length of the limiting strip is less than the opening spacing of the limiting frame.

[0011] Preferably, the inner layer of the cover and bottom surface is made of non-woven fabric, and the outer layer of the cover and bottom surface is made of leather.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model uses a limiting frame and limiting strip to limit and protect the certificate when the envelope is closed. When the envelope is opened, the user can directly pull out the certificate to one side for replacement.

[0014] 2. This utility model features a raised strip that increases the gap between the certificate and the bottom surface. When placed, there is no pressure difference between the certificate and the bottom surface, making it easier to remove the certificate when taking it out. Attached Figure Description

[0021] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figures 1-3 In this embodiment, an easy-to-replace certificate cover is provided, including a cover 1 and a bottom 2. A connecting strap 8 connects the cover 1 and the bottom 2. A limiting frame 3 is fixedly connected to the inner side of the bottom 2. The limiting frame 3 has an opening on the side away from the cover 1. A slot 31 is opened in the limiting frame 3. A limiting strip 4 is fixedly connected to the side of the cover 1 away from the bottom 2. The limiting strip 4 can be located at the opening of the limiting frame 3.

[0024] Multiple raised strips 6 are fixedly connected inside the bottom surface 2 between the limiting frames 3. The middle of the raised strips 6 is raised, and the height of the raised strips 6 is lower than the height of the upper end of the limiting frame 3.

[0025] When in use, flip the cover 1 over and place it on the bottom surface 2. The limiting strip 4 can be located at the opening of the limiting frame 3, and the certificate cannot be moved out of the slot 31. When the cover 1 is flipped open, the user can slide the certificate to one side and slide the certificate out of the slot 31. The raised strip 6 increases the gap between the certificate and the bottom surface 2 to prevent the certificate from being stuck to the bottom surface 2, making it easier to slide the certificate out and replace it.

[0026] In this embodiment, specifically, one end of the limiting frame 3 is provided with a slanted opening 32, and one side of the bottom surface 2 is provided with a slanted surface 21. Through the slanted surface 21 and the slot 31, it is convenient to insert the corner of the certificate into the slot 31 when inserting the certificate.

[0027] In this embodiment, specifically, the raised strip 6 has multiple grooves 61. The multiple grooves 61 increase the friction between the certificate and the raised strip 6, preventing the thin certificate from sliding directly out of the slot 31.

[0028] In this embodiment, specifically, a magnetic block 22 is embedded inside the inclined surface 21, and the limiting strip 4 is made of iron and can fit against the inclined surface 21. By adhering to the inclined surface 21 with the limiting strip 4, the cover 1 is adhering to the bottom surface 2, making the cover difficult to open.

[0029] In this embodiment, a retrieval opening 7 is specifically provided on the inclined surface 21. Through the retrieval opening 7, the user can push one side of the certificate up, thereby facilitating the retrieval of the certificate's side.

[0030] In this embodiment, specifically, the cover 1 has an observation port 5, and the inside of the observation port 5 is made of transparent plastic. The transparent PVC material allows the certificate content to be displayed, and when there are enough certificates, they can be identified directly without opening the cover.

[0031] In this embodiment, specifically, the length of the limiting strip 4 is less than the opening spacing of the limiting frame 3. The limiting strip 4 can easily fit into the opening of the limiting frame 3.

[0032] In this embodiment, specifically, the inner layer of the cover 1 and the bottom 2 is made of non-woven fabric, and the outer layer of the cover 1 and the bottom 2 is made of leather. The non-woven fabric prevents the certificate from directly contacting the leather and causing scratches, while the leather serves both aesthetic and protective purposes.

[0033] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
