Description

Technical Field

[0001] The utility model relates to the technical field of experimental teaching aids and instruments, and particularly relates to a storage box for experimental teaching aids and instruments. Background Technique

[0002] Experimental teaching aids and instruments, namely experimental instruments, are instruments used in specific experiments of natural science, mainly used in physics, chemistry, and biology. Commonly used modern experimental instruments include test tubes, beakers, evaporating dishes, crucibles, alcohol lamps, Buchner funnels, washing bottles, drying tubes, analytical balances, measuring cylinders, volumetric flasks, burettes, measuring device sets, etc.

[0003] When storing existing experimental instruments, on the one hand, there is no suitable area for distinguishing the storage of instruments of different sizes. Storing different instruments together may cause collision damage during transportation. On the other hand, when carrying the storage box, a general storage box is in the form of a cuboid. When placed vertically, the contact area with the placement surface is small, which may cause the overall storage box to tip over and damage the instruments inside the storage box.

[0004] In the patent document with the publication number CN218594875U, a storage box for experimental teaching aids and instruments is disclosed. Both the protection pad two and the protection pad one are made of foam pads, and the protection pad three is made of sponge. The foam pad can reduce the impact of collision, and the sponge can also reduce the impact of collision. By using the protection pad one, the protection pad two, and the protection pad three to reduce the impact of collision, it is convenient to effectively protect the experimental instruments in the storage box and avoid damage to the experimental instruments when being impacted.

[0005] However, when this storage box for experimental teaching aids and instruments is in use, it does not distinguish and place instruments of different volumes. During transportation, the instruments may be damaged due to collision between the instruments. Therefore, a storage box for experimental teaching aids and instruments needs to be proposed. Content of the Utility Model

[0006] The purpose of the utility model is to provide a storage box for experimental teaching aids and instruments to solve the problem of storing experimental instruments mentioned in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A storage box for experimental teaching aids and instruments, including a storage box and a box cover rotatably connected to the top of the storage box. A storage mechanism is arranged inside the storage box, and a limiting mechanism is arranged on one side of the box cover;

[0008] The storage mechanism includes a partition board, a horizontal board, an elastic band I, a push-pull board, an elastic band II, a limit board, an elastic soft pad, an installation groove, a limit post, a side board, and a limit screw. The partition board is fixedly connected to the inner wall of the storage box. The horizontal board is fixedly connected to the right side of the partition board. The elastic band I is arranged on the top of the horizontal board. The push-pull board is movably connected to the right side inner wall of the storage box. The elastic band II is arranged on the top of the push-pull board. The limit board is arranged on the left side inside the storage box.

The limit screw is threadedly connected to one side of the side board.

[0009] Preferably, sponge pads are arranged on the inner walls of the storage box, and the sponge pads are used to protect the experimental instruments.

[0010] Preferably, sponge pads are arranged on the tops of the horizontal board and the push-pull board. The elastic band I and the elastic band II are respectively evenly distributed in three on the tops of the horizontal board and the push-pull board. The elastic band I fixes the small-volume instruments and, in cooperation with the sponge pad on the top of the horizontal board, protects the experimental instruments.

[0011] Preferably, two through holes matching the limit posts are opened through the top of the limit board, and the limit posts are arranged to limit the limit board.

[0012] Preferably, a threaded hole matching the limit screw is opened through one side of the side board. When the limit screw is tightened, it can directly act on the inner wall of the installation groove to fix the limit board.

[0013] Preferably, the limiting mechanism includes a limit block, a circular groove, a circular baffle, a spring, a connecting rod, a connecting block, a square groove, and a bracket. The circular groove is opened on one side of the storage box. The circular baffle is movably connected to the inner wall of the circular groove. The connecting rod is fixedly connected to one side of the circular baffle. The limit block is fixedly connected to one side of the connecting rod. The connecting block is fixedly connected to the inner wall of the circular groove. The spring is movably connected to the outside of the connecting rod. The square groove is opened on one side of the storage box. The bracket is arranged on the inner wall of the square groove.

[0014] Preferably, a square groove matching the limit block is opened on one side of the box cover. When the limit block is inserted into the inner wall of the square groove, the box cover can be limited.

[0015] Preferably, a through hole matching the connecting rod is opened through one side of the connecting block. The connecting rod is slidably connected to the inner wall of the through hole, and the connecting block limits the connecting rod.

[0018] 2. The experimental teaching aid instrument storage box, through the provided limiting mechanism, can pull out the limiting block, cover the box lid, and then release the limiting block. At this time, the limiting block will rebound under the action of the spring's resilience, and one end of the limiting block will catch into the inner wall of the groove provided on one side of the box lid to limit the box lid. A bracket with an interference fit is provided in a square groove on one side of the storage box. After pulling out all the brackets, the storage box can be placed vertically, saving the placement space at this time, facilitating the carrying and storage of the storage box, and avoiding damage to the internal instruments caused by the unstable vertical placement and tipping of the storage box.

The push-pull plate 104 at the bottom can be pulled out. Elastic bands 103 and 105 are arranged on the top of the cross plate 102 and the push-pull plate 104, which can clamp the experimental teaching aid instruments. Cooperating with the sponge pads arranged on the top of the cross plate 102 and the push-pull plate 104, the experimental teaching aid instruments can be fixed and protected.

[0035] Furthermore, the large-sized experimental teaching aid instruments can be placed on the left side inside the storage box 1. Adjust the height of the limiting plate 106 to place the experimental teaching aid instruments at the bottom of the limiting plate 106, and press the limiting plate 106 against the top of the experimental teaching aid instruments. At this time, the elastic soft pad 107 will deform and completely fit the experimental teaching aid instruments. Finally, tighten the limiting screw 111 to fix the limiting plate 106. At this time, the experimental teaching aid instruments can be fixed and protected.

[0036] Further, through the provided limit mechanism, the limit block 201 can be pulled to cover the box cover 2 and then released. At this time, the limit block 201 will rebound under the action of the resilience of the spring 204, and one end of the limit block 201 will snap into the inner wall of the groove provided on one side of the box cover 2 to limit the box cover 2.

[0037] Furthermore, a bracket 208 connected by interference fit is provided in a square groove 207 on one side of the storage box 1. After all the brackets 208 are pulled out, the storage box 1 can be placed vertically. At this time, the placement space can be saved, which is convenient for carrying and storing the storage box 1 and avoids damage to the internal instruments caused by the unstable vertical placement and tipping over of the storage box 1.
