Description

Technical Field

[0001] This utility model relates to the field of teaching material placement devices, and in particular to a teaching material organization device. Background Technology

[0002] In teaching, we often need to use materials and documents. Due to the large quantity, we often need to use special organizing devices to store and organize them. This not only optimizes the space occupied, but also makes it easier to find and carry them later. Common material organizing devices include folders, file bags, and shelves.

[0003] Conventional teaching material racks typically have openings at the front and top to facilitate vertical placement of materials. Dividers on the inside of the rack allow for categorization of different types of materials. However, when placing soft materials such as test papers, worksheets, and reference sheets, these materials easily slip out when placed vertically. Therefore, a teaching material organizing device is needed that can change the rack's placement method to accommodate soft materials. Utility Model Content

[0004] The purpose of this invention is to provide a teaching material organization device to overcome the shortcomings of conventional racks which have a relatively limited range of placement methods.

[0005] The technical solution to achieve the above objective is: a teaching material organization device, including a placement rack, a plurality of partitions are provided inside the placement rack, the placement rack is in the shape of a square tube, and openings are provided on the front side wall and the top side wall of the placement rack, and a first adjustment mechanism is provided on the placement rack.

[0006] The first adjustment mechanism includes a mounting plate, connecting blocks, a first through hole, a limiting rod, a rotating shaft, a cover plate, a limiting hole, and a rotating hole. The mounting plate is connected to the top corner of the placement frame. A rotating hole is opened on the side wall of the mounting plate. A rotating shaft is rotatably connected to the side wall of the rotating hole. A cover plate is connected to the side wall of the rotating shaft. A limiting hole is opened at the end of the cover plate away from the rotating shaft. Two symmetrically distributed connecting blocks are connected to the top side wall and the rear side wall of the placement frame. A first through hole is opened on the side wall of the connecting blocks. The side wall of the limiting rod passes through the limiting hole and the first through hole.

[0007] An auxiliary mechanism is provided on the cover plate, and a second adjustment mechanism is provided on the placement rack.

[0008] Preferably, the mounting plate is L-shaped, and the rotating hole is located on the outer side of the top end of the mounting plate and the outer side of the rear end of the mounting plate.

[0009] Preferably, the baffle is located between two symmetrically distributed connecting blocks, and the limiting hole can be aligned with the first through hole.

[0010] Preferably, the second adjustment mechanism includes a sliding groove, a first sliding block, a square hole, a guide rod, a screw hole, a screw, a second sliding block, a second through hole, and a sliding hole. The bottom end of the partition is connected to the first sliding block. The inner bottom end of the placement frame has a sliding groove. The side wall of the sliding groove is slidably connected to the first sliding block. The rear side wall of the placement frame has a square hole. The side wall of the square hole is connected to the guide rod. The side wall of the guide rod has multiple screw holes. The rear side wall of the partition is connected to the second sliding block. The side wall of the second sliding block has a sliding hole. The side wall of the sliding hole is slidably connected to the guide rod. The rear side wall of the second sliding block has a second through hole. A screw is inserted into the second through hole.

[0011] Preferably, the second through hole and the screw hole are distributed in parallel.

[0012] Preferably, the thickness of the front sidewall of the partition is greater than the thickness of the rear sidewall of the partition, and the shape of the partition is trapezoidal.

[0013] Preferably, the auxiliary mechanism includes a through hole, a bottom groove, a bottom hole, a spring, a blocking block, and a push handle. The side wall of the blocking plate has a through hole, the bottom end of the through hole has a bottom groove, the side wall of the bottom groove has a bottom hole, the inner bottom end of the bottom groove is connected to a spring, the top end of the spring is connected to a blocking block, and the bottom end of the side wall of the blocking block is connected to a push handle.

[0014] Preferably, the through hole can be aligned with the square hole, the length of the through hole is greater than the length of the square hole, the blocking block is located inside the bottom groove, the push handle is located inside the bottom hole, and the length of the bottom hole is less than the length of the bottom groove.

[0015] The beneficial effects of this utility model are:

[0016] 1) When the cover is rotated to the top of the shelf, it covers the top opening of the shelf. At this time, place the left or right end of the shelf against the table, so that the original top opening of the shelf faces to both sides. The shelf changes from a vertical to a horizontal position. Soft paper materials can then be placed horizontally on the shelf. Utilizing the trapezoidal shape of the shelf, the side walls of the shelf are inclined, allowing the soft paper materials to slide inwards, thereby improving the stability of the soft paper materials and preventing them from easily falling from the front exit of the shelf. When the cover is rotated to the outer rear end of the shelf, the top opening of the shelf is open, and teaching materials can be placed vertically inside the shelf. The shelf is used to separate different types of materials, ensuring the normal use of the shelf.

[0017] 2) Move the partition, which drives the first slider and the second slider to move, thereby adjusting the distance between the partitions to accommodate different types of materials in different quantities and to allocate space within the shelf. The first slider slides along the slide groove, and the second slider moves along the guide rod through the slide hole. The second slider drives the second through hole to move, aligning the second through hole with the screw hole. The screw is then passed through the second through hole and screwed into the screw hole, thereby achieving the fixing effect of the partition. Attached Figure Description

The sliding groove 501 and the guide rod 504 are distributed in parallel.

[0038] The movable partition 2 moves the first slider 502 and the second slider 507, thereby adjusting the distance between the partitions 2 to accommodate different types of materials in different quantities, thus allocating space within the storage rack 1. The first slider 502 slides along the slide groove 501, and the second slider 507 moves along the guide rod 504 through the slide hole 509. The second slider 507 moves the second through hole 508, aligning it with the screw hole 505. The screw 506 passes through the second through hole 508 and is screwed into the screw hole 505, thereby achieving the fixing effect of the partition 2.

[0039] When the cover plate 306 rotates, it will drive the auxiliary mechanism 4 to rotate synchronously. When the cover plate 306 drives the limiting hole 307 to align with the first through hole 303 on the connecting block 302 at the rear end of the placement rack 1, the through hole 401 will rotate synchronously to align with the square hole 503. At this time, pull down the push handle 406. The push handle 406 pulls down the cover block 405, and the cover block 405 compresses the spring 404 downward, so that the cover block 405 moves into the bottom groove 402 and opens the through hole 401, so that the screw 506 can be turned easily and the cover plate 306 can be prevented from blocking the square hole 503. Release the push handle 406, and the spring 404 will push the cover block 405 to cover the through hole 401, thereby preventing the data from falling from the through hole 401.
