[0035] The following will describe a retractable air track of the present utility model in more detail with reference to the schematic diagrams, in which the preferred embodiments of the present utility model are shown. It should be understood that those skilled in the art can modify the present utility model described herein while still achieving the advantageous effects of the present utility model. Therefore, the following description should be understood as a broad knowledge for those skilled in the art and not as a limitation to the present utility model.
[0036] For clarity, not all features of the actual embodiments are described. In the following description, well-known functions and structures are not described in detail because they would obscure the present utility model with unnecessary details. It should be considered that in the development of any actual embodiment, a large number of implementation details must be made to achieve the specific goals of the developer, such as changing from one embodiment to another according to the relevant system or commercial limitations. Additionally, it should be considered that such development work may be complex and time-consuming, but it is only routine work for those skilled in the art.
[0037] In the following paragraphs, the present utility model will be described more specifically by way of example with reference to the accompanying drawings. The advantages and features of the present utility model will be clearer according to the following description and the claims. It should be noted that the drawings are all in a very simplified form and use non-precise scales, only for the purpose of conveniently and clearly assisting in explaining the embodiments of the present utility model.
[0038] As mentioned in the background art, there are currently some limitations and deficiencies in the air track system, including that the accessories are easily lost when stored separately, and the storage space occupied is large, and the equipment is difficult to effectively store, affecting the cleanliness and use efficiency of the laboratory.
[0039] In view of this, as Figure 1 or Figure 2 shown, the present utility model provides a retractable air track, and the air track includes a storage box 1, air track ends 2, and a track main body 3; the storage box 1 is connected below the track main body 3 for storing the accessories of the air track, and the air track ends 2 are symmetrically arranged at both ends of the track main body 3 and the storage box 1.
[0040] In this embodiment, the accessories of the air track include a glider 46, a light baffle 41, a counterweight iron 42, a magic tape bracket 45, a magnet bracket 44, a spring bracket 43, a photogate bracket 47, a limit bracket 48, and so on. These accessories can be arranged on the track main body 3 as needed during experimental use.
[0041] Specifically, as Figure 3As shown, the storage box 1 includes a storage box main body 11 and a storage box movable panel 12. At least one storage box movable panel 12 is connected to the storage box main body 11, and the storage box movable panel 12 is used to open and close the storage box 1. The number of the storage box movable panels 12 is schematically shown as 2 in the figure, and the 2 storage box movable panels 12 are arranged side by side.
[0042] The storage box movable panel 12 is made of galvanized sheet by spraying. The galvanized sheet has good corrosion resistance, which can protect the panel from the erosion of moisture, chemical substances and environmental factors, and extend the service life. Moreover, the galvanized layer can increase the wear resistance and scratch resistance of the panel, making it more durable in daily use.
[0043] At least one hinge device 121 is provided on the storage box movable panel 12. As Figure 4 shown, the hinge device 121 is semicircular. The semicircular hinge device 121 can realize the smooth rotation after the storage box movable panel 12 is hinged to the storage box main body 11. Since the hinge device 121 is provided with a first convex edge 1211 and the storage box movable panel 12 is provided with a first card slot 122, after the first convex edge 1211 is clamped with the first card slot 122, the storage box movable panel 12 as shown in Figure 5 can be obtained. As Figure 7 shown, a first protrusion 26 is provided at the bottom of the air cushion guide rail end 2. The storage box main body 11 and the hinge device 121 pass through the first protrusion 26 respectively to realize the hinge between the two.
[0044] In addition, at least one switch device is provided on the storage box 1. In this embodiment, the switch device is a push-type magnetic button 13. As Figure 6 shown, the push-type magnetic button 13 can be installed on the guide rail main body 3 above the storage box 1, and there is an opening on the storage box movable panel 12 to expose a part of the push-type magnetic button 13. The push-type magnetic button 13 enables the user to quickly open or close the storage box 1 through a simple pressing action, which can improve the convenience of use. The number of the push-type magnetic buttons 13 is schematically shown as 2 in the figure. In addition, since the magnetic attraction mechanism depends on magnetic force rather than a physical lock, the wear of the mechanical lock can be reduced, thereby improving the durability and the service life of the product.
[0045] In this embodiment, as Figure 6 shown, at least one partition board 14 is provided in the storage box 1. The figure schematically shows two partition boards 14, which divide the storage box 1 into 2 sub-storage boxes. Since the air cushion guide rail is relatively long, the partition board 14 is installed between the storage boxes 1, which can enhance the load-bearing capacity of the storage box 1.
[0046] In this embodiment, if Figure 1 or Figure 2 As shown, the guide rail body 3 is located above the storage box 1, and the air cushion guide rail end 2 is symmetrically arranged at both ends of the guide rail body 3 and the storage box 1. Figure 7 As shown, the air cushion guide rail end 2 is L-shaped, and a first platform 29 is provided on the air cushion guide rail end 2, and the guide rail body 3 is threadedly connected to the first platform 29. The first platform 29 is used to connect the two ends of the guide rail body 3 to maintain the stability of the air cushion guide rail.
[0047] In this embodiment, if Figure 7 As shown, the air cushion track end 2 also includes an adjustment bracket 21, a pulley 22, a spring hook 25, a track bracket 23, and an adjustment foot 24. The adjustment bracket 21 and pulley 22 are located on the outside of one of the air cushion track ends 2. The pulley 22 is threadedly attached to the adjustment bracket 21 and has a groove on the pulley 22 for attaching the string used in the experiment. The adjustment bracket 21 and pulley 22 allow the string used to hang objects to be aligned with the slider 46 during the experiment, ensuring accuracy.
[0048] In addition, the spring hook 25 is set on the inner side of the two air cushion guide rail ends 2. The main function of the spring hook 25 is to fix the slider 46 to facilitate preparation before the experiment begins. Through the spring hook 25, the slider 46 can be stably mounted on one end of the air cushion guide rail, ensuring that the slider 46 will not move before the experiment begins. The track bracket 23 and the adjustment foot 24 are set at the bottom of the air cushion guide rail end 2. The adjustment foot 24 is threaded onto the track bracket 23 and is used to adjust the horizontal height of the air cushion guide rail to ensure the accuracy of the experiment.
[0049] In this embodiment, if Figure 8 or Figure 9 As shown, the upper end of the air cushion guide rail end 2 is provided with a second convex edge 27, and the end away from the second convex edge 27 is provided with a second slot 28, and the second convex edge 27 matches the second slot 28, as shown in FIG. Figure 10As shown, multiple of the air cushion rails can be stacked. Through the matching design of the second convex edge 27 and the second card slot 28, the modularization of the air cushion rail can be achieved. In a laboratory or teaching environment, space is often a precious resource. By allowing multiple air cushion rails to be stacked, space can be effectively saved. Especially when not in use, multiple air cushion rails can be compactly stacked to reduce the occupied space. In addition, when multiple air cushion rails are stacked together, they can be transported and stored as a whole, which can not only reduce transportation costs but also simplify storage management.
[0050] In this embodiment, the rail body 3 is made of aluminum alloy, and two rows of evenly distributed air holes 31 are regularly arranged thereon. The main function of the air holes 31 is to provide necessary air flow for the air cushion rail to form an air cushion. For example, when the air flow passes through the air holes 31, an air layer will be formed between the rail body 3 and the slider 46, thereby reducing friction and enabling the slider 46 to move more smoothly on the rail body 3. The rail body 3 is made of aluminum alloy because the density of aluminum alloy is relatively low, making the rail body 3 lighter in weight and convenient for handling and installation. In addition, because it also has high strength, it can withstand greater pressure and impact force, ensuring the stability and durability of the rail body 3 during use.
[0051] In addition, as Figure 1 or Figure 2 shown, long strip-shaped third card slots 32 are provided on both sides of the rail body 3. The photogate bracket 47 and the limit bracket 48 can be clamped in the third card slots 32. The photogate bracket 47 and the limit bracket 48 are used to measure the speed and position of the slider 46 in the experiment. The design of the third card slots 32 allows the photogate bracket 47 and the limit bracket 48 to be flexibly installed and moved on both sides of the rail body 3, facilitating the adjustment of their positions according to experimental requirements.
[0052] In this embodiment, as Figure 1 shown, the slider 46 is used to slide on the air cushion rail, and different experimental accessories can be fixed thereon, such as a magic tape bracket 45, a magnet bracket 44, a counterweight iron 42, a light blocking plate 41, etc.
[0053] The usage steps of the collapsible air cushion rail in this embodiment are as follows:
[0054] S1: Prepare the experimental environment
[0055] Ensure that the experimental area is clean, flat, and there is no obvious vibration source.

[0063] Ensure that the assembled air track is placed horizontally. Use the spring hook 25 to fix the slider 46 at one end of the guide rail body 3 and get ready for the experiment.
[0064] S4: Adjust the air track
[0065] Use the track bracket 23 and the adjusting feet 24 to adjust the level of the air track to ensure that the air track is completely horizontal. Check whether the air holes 31 are unobstructed to ensure normal air cushion effect.
[0066] S5: Conduct the experiment
[0067] Place the experimental object (such as a small ball, a slider, etc.) on the slider 46.
[0068] Release the slider 46 through the spring hook 25 and observe the movement of the object on the air track. Use the photogate bracket 47 to measure the speed of the object and record the experimental data.
[0069] S6: Data recording and analysis
[0070] Record all experimental data, including the speed, position of the object, etc. Analyze the data to verify the experimental hypothesis, such as physical laws like the law of conservation of momentum.

[0077] In summary, in a collapsible air track provided by an embodiment of the present utility model, by adding a storage box 1 that can be opened and closed at the bottom of the rail body 3, it is possible to centrally store the accessories of the air track, thereby reducing the risk of the accessories being lost and saving storage space in the laboratory.
[0078] Furthermore, through the design that the second convex edge 27 at the upper end of the air track end 2 can match the second card slot 28 at the lower end, multiple air tracks can be stacked for storage, effectively utilizing the vertical space and reducing the storage area required in the laboratory.
[0079] The above is only the preferred embodiment of the present utility model and does not impose any limitation on the present utility model. Any person skilled in the art within the technical field, without departing from the technical solution of the present utility model, making any form of equivalent substitution or modification and other changes to the technical solution and technical content disclosed by the present utility model, all fall within the content of the technical solution of the present utility model and still belong to the protection scope of the present utility model.
