Problems solved by technology

[0004] Parents are very concerned about their children's learning, but they have been in the society for a long time, and they are not very flexible in answering the test questions in the student era. They are powerless in education, and there are QR code test papers. Parents or children can scan the QR code test papers. Checking the answers and analysis of relevant test questions will help children learn better, but many existing test papers do not have QR codes, and the existing ordinary printers do not have a paper slot the size of the test paper, so a A device that can print QR codes on test papers

Embodiment 1

[0023] refer to Figure 1 ~ Figure 4 , a two-dimensional code learning device for test papers, at least including a base frame 1 and a laser engraving head 2, an adjustment device is fixed on the upper wall of the base frame 1, and the adjustment device is detachably installed with the generation head 2. On the upper wall of the base frame 1 and below the generating head 2, a bearing frame 3 is fixed. The bearing frame 3 is a groove structure, and one side of the bearing frame 3 is movably connected with a pressing frame, and the pressing frame includes a pressing rod 4, a special-shaped Spring 5, pin 6; one end of the pressing rod 4 is movably connected with the bearing frame 3 through the pin 6, the special-shaped spring 5 is set on the outer circumferential surface of the pin 6, and the acting ends of the two ends of the special-shaped spring 5 respectively act on Between the bearing frame 3 and the pressing rod 4, the other side of the bearing frame 3 and the upper wall of...

Embodiment 2

[0026] refer to Figure 1 ~ Figure 3 Compared with Embodiment 1, the difference of this embodiment is that the adjustment device includes a slide rail 12, a slide block 13, a support frame 14, a guide tube 15, and a guide tube 16, and the slide rail 12 is parallel to the bearing frame 3 is fixed on the upper wall of the base frame 1, the slider 13 is fitted on the slideway of the slide rail 12, one end of the support frame 14 is fixed on the slider 13 perpendicular to the slide rail 12, and the guide tube 15 supports the frame horizontally 14 is fixed on the other end of the support frame 14, and the angle between the guide tube 15 and the support frame is a right angle, the guide tube 16 is movably inserted in the guide tube 15, and the generating head 2 is detachably connected to one end of the guide tube 16 , and located above the carrier 3.

[0027] In actual use: the slider 13 moves on the slide rail 12, and at the same time drives the support frame 14 to move, and the m...

Embodiment 3

[0029] refer to Figure 1 ~ Figure 3 Compared with Embodiment 1, the difference of this embodiment is that: the slide block 13 and the guide pipe 15 are provided with threaded holes, and screw rods 17 are provided in the threaded holes.

[0030] During actual use: after the slider 13 moves, the screw rod 17 on the rotating slider 13 can temporarily fix the slider to prevent movement. After the guide tube 16 moves, rotate the screw rod 17 on the guide tube 15 to fix the guide tube 16 Temporary fastening to prevent movement.

Abstract

The invention relates to the field of education teaching, in particular to two-dimensional code learning equipment for test paper. The equipment at least comprises a base frame and a generating head of laser engraving equipment. An adjusting device is fixed on the upper wall surface of the base frame, the adjusting device is detachably provided with the generating head, a bearing frame is fixed onthe upper wall surface of the base frame and located below the generating head, the bearing frame is of a groove structure, one side of the bearing frame is movably connected with a pressing frame, and the pressing frame comprises a pressing rod, a special-shaped spring and a pin shaft; and one end of the pressing rod is movably connected with the bearing frame through a pin shaft, and the outercircumferential surface of the pin shaft is sleeved with the special-shaped spring. Two-dimensional codes can be printed on the test paper, the printing position can be adjusted, the content cannot becovered, the teacher generates the two-dimensional code, family members can be helped to better educate children, and the children can better understand test questions.

Description

[0001] Technical field [0002] The invention relates to the field of education and teaching, in particular to a two-dimensional code learning device for test papers. Background technique [0003] Two-dimensional code is also called two-dimensional barcode. The common two-dimensional code is QR Code. The full name of QR is Quick Response. It is a very popular coding method on mobile devices in recent years. It can store more The information can also represent more data types. [0004] Parents are very concerned about their children's learning, but they have been in the society for a long time, and they are not very flexible in answering the test questions in the student era. They are powerless in education, and there are QR code test papers. Parents or children can scan the QR code test papers. Checking the answers and analysis of relevant test questions will help children learn better, but many existing test papers do not have QR codes, and the existing ordinary printers do ...
