Description

Technical Field

[0001] This utility model relates to the field of storage cabinet technology, specifically a scientific teaching aid storage cabinet with protective functions. Background Technology

[0002] With science education receiving increasing attention today, science teaching aids, as important tools to assist teaching, are becoming increasingly diverse in type and quantity, covering a wide range of items from basic physics experimental equipment to complex electronic components. These teaching aids not only play a key role in teaching activities, but also, due to their often precise structures and fragile nature, place high demands on the storage environment.

[0003] Traditional storage cabinets have fixed internal space, making it difficult to accommodate the storage needs of scientific teaching aids of different sizes and shapes. This can easily lead to the squeezing and collision of teaching aids, especially in the classroom environment where students are active and occasional misbehavior or careless operation can cause accidents, such as bumping into the storage cabinet or forcefully opening and closing the cabinet door. The vibrations generated by these actions can easily deform and damage the teaching aids inside the cabinet. Therefore, a scientific teaching aid storage cabinet with protective functions is proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a scientific teaching aid storage cabinet with protective function to overcome the above-mentioned shortcomings of the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A scientific teaching aid storage cabinet with protective function includes a storage cabinet body, a protective cover hinged to the left side of the storage cabinet body, a partition fixedly installed inside the storage cabinet body, a vertical plate fixedly installed on the top of the partition, a storage drawer inside the storage cabinet body, and a compression protection mechanism located above the storage drawer inside the storage cabinet body.

[0007] The compression protection mechanism includes a bidirectional lead screw rotatably installed inside the storage cabinet body. Two internal threaded blocks are installed on the external threads of the bidirectional lead screw. A slider penetrating into the interior of a partition is fixedly installed on the top of each of the two internal threaded blocks. Both sliders are slidably installed inside the partition. A connecting rod is rotatably installed on the bottom of each of the two internal threaded blocks. A rigid plate is rotatably installed on the bottom of the two connecting rods. A first sponge pad is fixedly installed on the bottom of the rigid plate. The first sponge pad is located above the storage drawer. The bottom areas of both the rigid plate and the first sponge pad are smaller than the bottom area of ​​the storage drawer.

[0008] The beneficial effects of this utility model are: when the bidirectional lead screw is rotated in the forward direction, the two internal threaded blocks approach each other, and the connecting rod pushes the hard plate and the No. 1 sponge pad to descend and enter the storage drawer. This allows the small scientific teaching aids inside the storage drawer to be squeezed and restricted. This design can effectively prevent the scientific teaching aids from being damaged when the storage cabinet is impacted, and significantly improves the protective performance and practicality of the storage cabinet.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the vertical plate divides the upper part of the partition into two storage compartments, and the inner walls of both storage compartments are fixedly installed with No. 2 sponge pads.

[0011] Furthermore, two No. 3 sponge pads are fixedly installed on the surface of the protective cover, with each of the two No. 3 sponge pads corresponding to the positions of the two storage compartments.

[0012] Furthermore, guide rails are fixedly installed on both the left and right sides of the inner wall of the storage cabinet body, and movable blocks are slidably installed inside the two guide rails. The two movable blocks are fixedly connected to the left and right sides of the storage drawer, respectively.

[0013] Furthermore, metal rods are fixedly installed inside both guide rails, and the two moving blocks are slidably installed on the outside of the two metal rods respectively.

[0014] Furthermore, a number of foam boards are fixedly installed inside the storage drawer, and the foam boards are distributed in a crisscross pattern inside the storage drawer. Attached Figure Description

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] Example 1, such as Figures 1-5 As shown, a scientific teaching aid storage cabinet with protective function includes a storage cabinet body 1, a protective cover 2 hinged to the left side of the storage cabinet body 1, a partition 3 fixedly installed inside the storage cabinet body 1, a vertical plate 4 fixedly installed on the top of the partition 3, a storage drawer 5 inside the storage cabinet body 1, and a compression protection mechanism located above the storage drawer 5 inside the storage cabinet body 1.

[0024] Specifically, the compression protection mechanism includes a bidirectional lead screw 6 rotatably installed inside the storage cabinet body 1. Two internal threaded blocks 7 are installed on the external threads of the bidirectional lead screw 6. A slider 8 that penetrates into the partition 3 is fixedly installed on the top of each of the two internal threaded blocks 7. The two sliders 8 are slidably installed inside the partition 3. A connecting rod 9 is rotatably installed on the bottom of each of the two internal threaded blocks 7. A rigid plate 10 is rotatably installed on the bottom of the two connecting rods 9. A first sponge pad 11 is fixedly installed on the bottom of the rigid plate 10. The first sponge pad 11 is located above the storage drawer 5. The bottom areas of the rigid plate 10 and the first sponge pad 11 are both smaller than the bottom area of ​​the storage drawer 5.

[0025] The storage cabinet body 1 is divided into two storage spaces by a partition 3. The upper part of the partition 3 is used to store large scientific teaching aids, while the storage drawer 5 below the partition 3 is used to store small scientific teaching aids. Two sliders 8 are slidably installed inside the partition 3, which can respectively restrict the two internal threaded blocks 7 to slide left and right below the partition 3. Rotating the bidirectional screw 6 in the forward direction can force the two internal threaded blocks 7 to move closer to each other. When the two internal threaded blocks 7 move closer to each other, the two connecting rods 9 installed at their bottom can push the hard plate 10 and the first sponge pad 11 to descend. After the hard plate 10 and the first sponge pad 11 descend into the storage drawer 5, the first sponge pad 11 can squeeze and restrict the small scientific teaching aids stored in the storage drawer 5. At this time, it can effectively prevent the scientific teaching aids from being damaged when the storage cabinet body 1 is impacted. Rotating the bidirectional screw 6 in the reverse direction forces the two internal threaded blocks 7 to move away from each other. The two connecting rods 9 can then pull the hard plate 10 and the first sponge pad 11 to rise, thus releasing the restriction on the small scientific teaching aids.

[0026] Example 2, as Figures 1-3 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0027] The vertical panel 4 divides the upper part of the partition 3 into two storage compartments, and the inner walls of both storage compartments are fixedly installed with No. 2 sponge pads 12.

[0028] This design allows for the separation of two storage compartments, which can hold two large science teaching aids. The installed No. 2 sponge pad 12 can mitigate the impact force between the large science teaching aids and the inner walls of the two storage compartments.

[0029] Example 3, as Figures 1-3 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0030] Two No. 3 sponge pads 13 are fixedly installed on the surface of the protective cover 2, and the two No. 3 sponge pads 13 correspond to the positions of the two storage compartments respectively.

[0031] This design allows the scientific teaching aids inside the storage cabinet body 1 to be protected when the protective cover 2 is closed. At this time, the two No. 3 sponge pads 13 are located in front of the two storage compartments, which can reduce the impact force between large scientific teaching aids and the protective cover 2.

[0032] Example 4, as Figures 1-4 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0033] Guide rails 14 are fixedly installed on both the left and right sides of the inner wall of the storage cabinet body 1. Movable blocks 15 are slidably installed inside the two guide rails 14. The two movable blocks 15 are fixedly connected to the left and right sides of the storage drawer 5 respectively.

[0034] With this configuration, the two moving blocks 15 are restricted to slide on both sides of the inner wall of the storage cabinet body 1 by the two guide rails 14 respectively. The two moving blocks 15 can restrict the storage drawer 5 to slide back and forth inside the storage cabinet body 1. Pulling the storage drawer 5 forward makes it convenient to store and retrieve small scientific teaching aids.

[0035] Example 5, as Figure 4 As shown, this embodiment is a further improvement based on embodiment 4, and its specific details are as follows:

[0036] Metal rods 16 are fixedly installed inside both guide rails 14, and two moving blocks 15 are slidably installed on the outside of the two metal rods 16 respectively.

[0037] With this configuration, the two moving blocks 15 can be stably confined within the two guide rails 14 by the two metal rods 16.

[0038] Example 6, as Figure 4 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0039] The interior of the storage drawer 5 is fixedly equipped with a number of foam boards 17, which are distributed in a crisscross pattern inside the storage drawer 5.

[0040] This design uses multiple foam boards 17 to divide the interior of the storage drawer 5 into multiple storage spaces to prevent adjacent small scientific teaching aids from coming into contact with each other.

[0041] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
