Abstract
Description
Technical Field
[0001] This utility model relates to the field of teaching device technology, and in particular to a test paper classification device. Background Technology
[0002] In today's teaching work, exams are an indispensable part, which inevitably results in a large number of test papers that need to be categorized and stored. Currently, teachers simply pile the test papers on their desks without categorizing or organizing them, leading to a messy situation. Furthermore, the test papers used in junior and senior high schools are quite long, making it inconvenient to fold them up and retrieve them later.
[0003] Publication number CN215125782U discloses a Chinese language teaching test paper sorting device, including a supporting mechanism and a fixing mechanism. The supporting mechanism includes a base, a placement box, and a front support plate. The placement box is installed inside the base, and two front support plates are provided at the front of the base. A slide rail is provided on both sides of the placement box inside the base, and a pull-out plate is provided inside the slide rail. The pull-out plate has a pull block with a pull hole. A fixing plate is installed on the upper surface of the base by screws. This utility model has a simple structure, reasonable design, and low production cost. It can not only neatly sort and place test papers, but also facilitate the retrieval of test papers, making it convenient for teachers to use. Moreover, the device can be placed on a desk, occupying little space, and is simple and practical, improving the utilization and tidiness of the desktop.
[0004] While the above-mentioned methods facilitate the extraction of test papers, the clamping and fixing of test papers requires a large number of rotating columns, rubber clamping wheels, and springs. The equipment has a complex test paper fixing structure and high manufacturing cost. Furthermore, it is difficult to re-sort and place test papers of the same type. Therefore, we propose a test paper sorting device. Utility Model Content
[0005] The main purpose of this utility model is to provide a test paper sorting device. By setting up a fixing unit and a separating unit, it solves the problems of complex test paper fixing structure, high manufacturing cost, and difficulty in secondary sorting and placing test papers of the same category.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a test paper sorting device, including a support base and two sorting boxes symmetrically fixed on the top surface of the support base, and further including: a fixing unit and a separating unit disposed on the sorting boxes;
[0007] The fixing unit includes a lead screw, a support block, and a pressure plate. The sorting box has a strip-shaped mounting groove on each of its two inner walls. The lead screw is mounted on one of the strip-shaped mounting grooves via a bearing. There are two support blocks, which are located on the two strip-shaped mounting grooves respectively. One of the support blocks is threadedly connected to the lead screw. The pressure plate is fixedly disposed between the two support blocks.
[0008] The separating unit includes a sliding rod, a slider, and a frame-shaped partition. A set of strip grooves are respectively opened on the inner walls of opposite sides of the sorting box. The sliding rod is fixedly installed on the strip groove. Several sliders are movably sleeved on the outer circumference of the sliding rod. A frame-shaped partition is fixedly installed between each pair of sliders at the same height, and the frame-shaped partition is located below the pressure plate.
[0009] Preferably, the fixing unit further includes a guide rod, which is fixedly mounted on another strip-shaped mounting groove and movably passes through another support block.
[0010] Preferably, a turntable is fixedly installed on the end face of the lead screw located outside the sorting box.
[0011] Preferably, the slide bar and the lead screw are arranged parallel to each other.
[0012] Preferably, two symmetrical storage grooves are formed on one side surface of the support base.
[0013] Preferably, the support base is fixedly provided with feet at the corners of its bottom surface.
[0014] Preferably, the support legs are provided in a total of four and arranged in a rectangular array.
[0015] Compared with the prior art, the test paper sorting device of this utility model has the following beneficial effects:
[0016] 1. In this utility model, by setting a fixing unit, after the test papers of the same major category are separated by the frame-shaped partitions in the classification box, by holding and rotating the screw in both directions outside the classification box, one of the support blocks connected to the screw threadedly can drive the pressure plate to rise and fall in the classification box under the force, and the other support block can slide and rise on the guide rod to cooperate with the frame-shaped partitions and provide auxiliary support. The pressure plate can press down all the frame-shaped partitions and the classified test papers to complete the unified fixing operation. The equipment has a simple test paper fixing structure and low manufacturing cost.
[0017] 2. In this utility model, by setting up a dividing unit, the sliding rod installed on the inner wall of the sorting box through the strip groove can slide and rise with the slider. Each frame-shaped partition can adjust the spacing as the slider slides. After different types of test papers are further divided by each frame-shaped partition, the stacking height can be flexibly adjusted. Moreover, the frame-shaped partition can press down on the corners of the stacked test papers, ensuring the neatness of the test paper stacking. The equipment has a good effect on the flexible placement of test papers. Attached Figure Description
