The invention discloses a test paper sealing folder which comprises a front page plate, a rear page plate, a first ridge plate, a second ridge plate, an upper sealing plate, a third ridge plate and a lower sealing plate. The front page plate, the rear page plate and the first ridge plate are integrally formed, the front page plate and the rear page plate are symmetrically connected to two edges of the first ridge plate, the second ridge plate is arranged at the upper end of the rear page plate, the upper sealing plate is connected with the second ridge plate, the third ridge plate is arranged at the lower end of the rear page plate, the lower sealing plate is connected with the third ridge plate, a plurality of corresponding binding holes are formed in the front page plate and the rear page plate, a plurality of tying locking bars are fixedly arranged on the rear page plate, a plurality of locking holes are formed in the front page plate, and the tying locking bars, the binding holes and the locking holes are in one-to-one correspondence to one another. The test paper sealing folder has the advantages that various inconvenience problems such as complicated sealing operation procedures and long time consumption of common sealing folders can be solved, and the shortcoming of low test paper confidentiality can be overcome.
Description
technical field [0001] The invention belongs to the field of binding devices, relates to a folder without a clamp, in particular to a test paper sealing folder. Background technique [0002] At present, in the field of education and teaching, the sealing of test papers mainly uses needles and threads to sew the finished test papers and kraft paper together and then stick a seal, or add a seal. The whole encapsulation process is complicated and time-consuming and inconvenient, and the confidentiality of the test papers is not strong, so it cannot serve the invigilators conveniently and quickly. Contents of the invention [0003] In view of this, the object of the present invention is to provide a test paper sealing folder. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A test paper sealing folder, including an integrally formed front panel, a rear panel and a first spine panel, the front panel and the rear ...
