Description

Technical Field

[0001] This utility model relates to the field of bracket technology, and in particular to a storage bracket for school laboratories. Background Technology

[0002] Laboratory storage racks are shelves specifically designed for storing and organizing laboratory equipment. Made of durable and corrosion-resistant materials, they feature a stable structure, categorized storage, and safety. They aim to improve laboratory space utilization and ease of operation, ensuring a clean and orderly laboratory environment.

[0003] Laboratory storage racks can be used to place various experimental equipment, such as test tubes, beakers, burettes, graduated cylinders, reagent bottles, etc., as well as to hang or store small tools such as pipettes, tweezers, test tube brushes, and even some experimental materials. They can help laboratory personnel organize and store experimental supplies in an orderly manner, keep the workbench clean and improve the efficiency of experimental operations.

[0004] However, the following problems were found in the implementation of the relevant technology: Generally, laboratory shelves are used to store experimental materials, and some of these materials are stored in glass containers. To make it easier to find them, users usually place the glass containers containing the experimental materials together. This can lead to a situation where there are many glass containers, and the containers placed in front may block the labels on the containers behind. When shorter users are looking for containers, they may have difficulty finding the experimental materials they need at a glance due to the obstruction, and they may have to search for the materials one by one. This will waste the user's time to a certain extent and increase the risk of other containers falling. In view of this, a storage rack for school laboratories is provided to overcome the above defects. Utility Model Content

[0013] This utility model has the following beneficial effects:

[0014] This utility model designs a storage rack for school laboratories. Through a design and coordination, components such as a sliding rod, a first spring, and a storage plate are combined. By rotating a knob, an elliptical block is rotated. The elliptical block presses against a contact block, causing a connecting block to move inward into the moving groove. This causes a clamping block to engage with a locking block. Then, the rebound action of the first spring causes the storage plate and the container placed on it to move upward. The upward movement of the storage plate removes the obstruction of the front glass container from the rear glass container, allowing the user to directly observe the label on the rear glass container and quickly find items.

[0015] This utility model designs a storage rack for school laboratories. Through a design that combines components such as a storage board, a rubber pad, and a placement slot, the storage slot at the top of the storage board facilitates the placement of glass containers. The rubber pad increases the friction between the object being placed and the placement slot, ensuring that the object will not fall out of the slot due to inertia when the storage board moves upward, thus ensuring the safety of the object.

There are two clamping blocks 17. By setting the clamping blocks 17, it is convenient to fix the card block 7 by clamping the clamping blocks 17.

[0029] Working principle:

[0030] When using this invention, the glass containers to be placed should first be arranged in order according to their size into the placement slots 10 at the top of the shelf 4. Rubber pads 5 are fixed to the inner sidewalls of the placement slots 10. The contact between the rubber pads 5 and the glass containers increases the friction between them, thus securing the glass containers. When the user needs to find a specific glass container, they can rotate the knob 3 on the front of the tray 2 to rotate the connecting rod 11. The rotation of the connecting rod 11 causes the elliptical block 16 fixed to the other end of the connecting rod 11 to rotate synchronously. The elliptical block 16 is located inside the rectangular slot 20, which is located on the tray 2. The inner side of 20 is also provided with a locking block 7 and a contact block 19. One side of the contact block 19 contacts the side of the elliptical block 16. By rotating the elliptical block 16, the elliptical block 16 presses the contact blocks 19 on both sides. By pressing the contact blocks 19, the contact blocks 19 and the connecting block 18 fixed on the other side of the contact blocks 19 move towards the inner side of the moving groove 14. The inner side of the moving groove 14 is provided with a second spring 15. The two ends of the second spring 15 are fixed to one side of the inner side of the moving groove 14 and one side of the connecting block 18, respectively. When the connecting block 18 moves towards the inner side of the moving groove 14, it will correspondingly press the second spring 15. The side of the connecting block 18 fixed with the contact block 19 is also fixed. There is a clamping block 17, which is slidably connected to the locking block 7. Therefore, when the connecting block 18 moves towards the inside of the moving groove 14, it will correspondingly cause the clamping block 17 to release from sliding with the locking block 7. The top of the locking block 7 is fixed to the bottom of the shelf 4, and the bottom of the shelf 4 is also fixed to the top of the slide rod 8. The bottom of the slide rod 8 is located inside the telescopic groove 13. A first spring 12 is provided inside the telescopic groove 13. The two ends of the first spring 12 are fixed to the bottom of the slide rod 8 and the bottom of the telescopic groove 13, respectively. After the clamping block 17 releases its restriction on the locking block 7, the locking block 7 and the shelf 4 will move upward under the rebound action of the first spring 12. The sliding blocks 9 fixed on the left and right sides of the shelf 4 will move upward through the interaction with the locking block 7. The fixed block 6 at the top of the tray 2 slides to ensure that the entire shelf 4 does not swing arbitrarily when moving. When the shelf 4 moves upward a certain distance, the labels on the various glass containers placed on the shelf 4 will be directly displayed to the user through the notch on the front side of the placement slot 10, making it convenient for the user to find the label fixed on the front of the glass container. This avoids the glass containers placed in the back row being blocked by the front row, making it difficult for the user to see the specific name of the glass container. It also avoids the user having to keep searching for the correct glass container, which would waste time and cause other glass containers to be knocked over. The tray 2 is also fixed with a support leg 1, which supports the entire device.

[0031] In this utility model, the knob 3, the first spring 12, the rubber pad 5 and other components are all existing technologies, and their working principle is consistent with that of similar products on the market, so they will not be described in detail here.
