Description

Technical Field

[0001] This utility model relates to the field of certificate protection technology, and in particular to a certificate protection cover. Background Technology

[0002] A certificate is proof that a worker possesses the necessary knowledge and skills to perform a particular occupation. It serves as an important reference for job seekers and employers, and is a primary basis for recruitment and hiring. Certificates are mainly divided into academic certificates, degree certificates, and various professional qualification certificates. Certificates are usually made of paper and are stamped with a seal in a designated location before issuance to confirm their validity. Because paper certificates are inconvenient to preserve and easily damaged by contamination, they are usually protected with a protective cover. Traditional certificate protective covers have some drawbacks. When the protective cover is applied to the certificate, it is easy for it to fall off the certificate because it is only fixed to the outside of the certificate by a clip and lacks an internal restraining structure. This makes it unable to effectively protect the certificate. Utility Model Content

[0013] 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.

[0014] like Figure 1-4As shown, a certificate protective cover includes a protective cover 1. An assembly auxiliary mechanism 3 is provided on the inner wall of the protective cover 1. A limiting auxiliary mechanism 4 is provided on the inner wall of the protective cover 1 near the assembly auxiliary mechanism 3. The assembly auxiliary mechanism 3 includes a connecting block 31 fixedly connected to the inner wall of the protective cover 1. A snap-fit ​​bracket 32 ​​is sleeved on the outer side of the connecting block 31. A limiting head 33 is fixedly connected to the inner wall of the snap-fit ​​bracket 32. A contact groove 34 is formed at the front end of the connecting block 31. A placement bracket 35 is fixedly connected to one end of the snap-fit ​​bracket 32. An airbag 36 is fixedly connected to the inner wall of the placement bracket 35. A suction cup 37 is fixedly connected to one end of the airbag 36. An air blowing port 38 is fixedly connected to the upper end of the airbag 36. The limiting auxiliary mechanism 4 includes a fixing frame 41 fixedly connected to the inner wall of the protective cover 1 near the connecting block 31. A limiting frame 42 is fixedly connected to the front end of the fixing frame 41.

[0015] In this embodiment, the outer side of the air inlet 38 is threaded with an airproof cover 39, the shape of the limiting head 33 is circular, the outer side of the limiting head 33 contacts the inner side of the contact groove 34, there are several sets of limiting heads 33 and contact grooves 34, the shape of the placement frame 35 is U-shaped, the shape of the suction cup 37 is trapezoidal, the air inlet 38 and the airbag 36 are connected, there is a gap between the limiting frame 42 and the fixing frame 41, and there are four sets of limiting auxiliary mechanisms 4.

[0016] Specifically, the user first removes the certificate, then presses it onto the suction cup 37, causing the suction cup 37 to hold the certificate firmly. Next, the user places the placement bracket 35 inside the protective cover 1, and the card holder 32 contacts the connecting block 31. The user then presses the placement bracket 35 downwards, causing the card holder 32 to engage outside the connecting block 31, and the limiting head 33 engages inside the contact groove 34, thus confining the placement bracket 35 within the protective cover 1. The user then inserts the first page of the certificate into the limiting frame 42, unscrews the airproof cap 39, and blows air into the airbag 36 through the air inlet 38, causing the airbag 36 to expand outwards. This pushes the certificate outwards, allowing the first page of the certificate to move within the limiting frame 42. The certificate's first page is then inserted into the fixing bracket 41 and the limiting bracket 42. The gas cover 39 is then screwed onto the air outlet 38 to prevent gas leakage from the airbag 36, thus confining the certificate within the protective skin 1 and preventing it from detaching from the outside of the certificate. The certificate is then pressed onto the suction cup 37, causing it to hold the certificate firmly. The placement bracket 35 is then inserted into the protective skin 1, the clip bracket 32 ​​is attached to the outside of the connecting block 31, and the limiting head 33 is engaged in the contact groove 34. This confines the placement bracket 35 within the protective skin 1, effectively preventing the certificate from detaching and ensuring the protective skin 1 provides effective protection for the certificate.

[0017] In this embodiment, an identification card 2 is fixedly connected to the front end of the protective skin 1. The protective skin 1 is U-shaped, the main material of the protective skin 1 is plastic, and the identification card 2 is rectangular.

[0018] Specifically, the certificate information is written on the surface of the identification card 2 to avoid misidentifying the certificate, thus enabling users to clearly and quickly find the specified certificate.

[0019] Working principle: In use, the user first removes the certificate, then presses it onto the suction cup 37, causing the suction cup 37 to hold the certificate firmly. Next, the placement bracket 35 is secured inside the protective cover 1, and the card holder 32 contacts the connecting block 31. The placement bracket 35 is then pressed downwards, and the card holder 32 is secured outside the connecting block 31. The limiting head 33 is then engaged inside the contact groove 34, thus securing the placement bracket 35 within the protective cover 1. The first page of the certificate is then secured into the limiting frame 42. The airproof cap 39 is then unscrewed, and air is blown into the airbag 36 through the air inlet 38, causing the airbag 36 to expand outwards. This pushes the certificate outwards, moving the first page of the certificate within the limiting frame 42, thus securing the first page of the certificate into the fixing frame 41 and the limiting frame 42. Then, screw the gas cover 39 onto the air inlet 38 to prevent gas leakage from the airbag 36, thus confining the certificate within the protective skin 1 and preventing the protective skin 1 from falling off the outside of the certificate. Then, write the certificate information on the surface of the identification card 2 to prevent misidentification of the certificate, allowing the user to clearly and quickly find the designated certificate. By pressing the certificate onto the suction cup 37, the suction cup 37 firmly holds the certificate. Then, the placement bracket 35 is clipped into the protective skin 1, the card holder 32 is clipped onto the outside of the connecting block 31, and the limiting head 33 is clipped into the contact groove 34, thus confining the placement bracket 35 within the protective skin 1. This achieves the purpose of confining the certificate within the protective skin 1, thereby preventing the certificate from falling off the protective skin 1 and allowing the protective skin 1 to effectively protect the certificate.
