Description

Technical Field

[0001] The present invention relates to the technical field of teaching equipment, and particularly to a carrying device for teaching equipment that facilitates the access to teaching utensils. Background Art

[0002] In chemical teaching experiments, the carrying device plays a crucial role in the management and use of experimental equipment, and is an important part to ensure the smooth progress of experiments and teaching quality. Traditional chemical experiment teaching involves a large number of experimental equipment, such as beakers, test tubes, reagent bottles, pipettes, measuring cylinders, etc. These equipment not only have a wide variety of types, but also are mostly made of glass or other fragile materials. Therefore, in the daily teaching process, how to safely and conveniently carry and manage these experimental utensils has become a key issue in teaching; frequent carrying and access are the norm in chemical experiment teaching. When teachers and students conduct different experiments, they often need to move various equipment between different areas of the laboratory. This frequent movement not only increases the complexity of experiment preparation, but also greatly increases the risk of equipment damage. If the carrying device is poorly designed or lacks functions, it is easy to cause bumps and breakages of experimental equipment, and even affect the accuracy of experiments and teaching effects; therefore, the requirements for the carrying device are very high, but the current carrying devices are not very suitable for use with teaching utensils.

[0003] First of all, during the transportation of existing teaching equipment, especially when dragging the equipment over uneven roads, the equipment often generates large vibrations. These vibrations not only affect the stability of the equipment, but may also damage the experimental equipment stored inside, resulting in inaccurate experimental results or even breakage of the equipment. Currently, common teaching equipment on the market lacks effective shock-absorbing designs and cannot provide sufficient protection under complex road conditions, greatly limiting the applicability and service life of the equipment;

[0004] Secondly, existing teaching experiment equipment is usually designed relatively fixedly, and the storage positions of the equipment are difficult to adjust and cannot be flexibly configured according to actual experimental needs. This fixity limits the scope of application of the equipment, making it insufficiently adaptable when conducting different types of experiments. Often, additional storage space or auxiliary equipment is required to accommodate different types of experimental equipment, which not only increases the complexity of experiment preparation, but also reduces teaching efficiency, bringing inconvenience to teachers and students;

[0005] Finally, during the experimental teaching process, the stable placement of experimental equipment is crucial. However, when adjusting the height of the partition or storing experimental equipment with existing devices, there are often problems with unstable fixation. For example, during the adjustment of the partition position or the placement of equipment, due to the lack of effective limiting and fixing devices, the equipment is prone to sliding or displacement, resulting in the dropping or damage of equipment during the experiment, and even affecting the smooth progress of the experiment. This instability seriously affects the safety and accuracy of experimental operations and poses a hidden danger to the teaching process. Summary of the Invention

[0006] In view of the deficiencies of the prior art, the present invention provides a handling device for facilitating the access of teaching utensils for teaching equipment, which solves the problem that the equipment cannot flexibly adjust the storage of teaching utensils.

[0015] Preferably, the multi-functional mechanism includes a storage frame, which is installed on the front and rear sides of the top frame and is symmetrically distributed up and down. A beaker rack is fixed on the left side of the top frame, and a test tube rack is arranged on the top of the beaker rack. The test tube rack is installed on the left side of the top frame.

[0016] Preferably, a ruler frame is installed on the right side of the top frame, and two limiting columns are slidably arranged inside the ruler frame. Two springs are sleeved on the outer wall of the two limiting columns. One end of the two springs is fixed inside the ruler frame, and a splint is fixed to the other end of the two springs.

[0017] Preferably, one side of the clamping plate is connected to one end of the second spring, and the other end of the second limiting column is fixed with a limiting plate.

[0018] Preferably, the shock absorbing mechanism includes a connecting plate, which is symmetrically distributed up and down, with the upper connecting plate fixed to the bottom of a partition, and the lower connecting plate fixed to a fixed plate. A docking frame is installed on one side of the connecting plate, a connecting rod is rotated inside the docking frame, and a docking shaft is rotated at one end of the connecting rod, and a slider is connected between the connecting rods through the docking shaft.

[0019] Preferably, a pressure block is fixed on one side of the connection plate, a docking frame is arranged between the pressure blocks, fixed frames are installed on both sides of the docking frame, and the sliding block slides in the fixed frame.

[0020] Preferably, a damper 1 is arranged between the pressure blocks, which is used for performing the first shock absorbing and buffering operation, and the output end of the damper 1 is fixed to the bottom end of the pressure block on the upper side, and a damper 2 is arranged inside the fixed frame, which is used for performing the second shock absorbing and buffering operation, and the output end of the damper 2 is fixedly connected to one side of the slider.

[0021] Preferably, the quick-release mechanism includes a plug post, which is installed on one side of the storage frame, a spring three is arranged inside the plug post, one end of the spring three is fixed in the plug post, an extrusion column is fixed to the other end of the spring three, a round ball is arranged inside the extrusion column, a magnet one is installed on the outer wall of the extrusion column, a magnet two is installed inside the plug post, and the magnets one and two repel each other magnetically.

[0022] Preferably, the cylinder output end is connected to the shock absorbing mechanism through a fixing plate.

[0023] Working principle: When placing experimental teaching equipment, the position of the partition one and the knob can be freely adjusted according to the chemical experiment alcohol lamp and physical light imaging equipment that need to be placed. When adjusting the position of the partition one, we need to turn the knob to drive the bolt to rotate, so as to drive the rubber pad to no longer fit with the top frame. At this time, the position of the partition one can be moved. When moving, the corresponding push plate will be squeezed and then pushed, so as to squeeze the limit column one under the restriction of the limit column one. Through the reaction force of the limit column one, the position of the knob can also be stabilized. After confirming the position of the partition one, turn the knob to make it pass through the bolt to let the rubber pad re-fit. The knob is fitted with the top frame to fix its position through the friction force generated, and the knob position can also be fixed by the spring 1 in the squeezed state, so that the position can be changed freely. In addition to placing experimental equipment, the corresponding test tubes or beakers that are difficult to place can be placed through the reserved holes of the beaker rack and the test tube rack. In addition, the position of the storage frame can also be used to place different small equipment, such as other chemical teaching experiment medicine bottles, etc., and the position of the ruler rack can be used to place different teaching rulers. Placing the teaching ruler on the position of the splint can be pushed by the spring 2, so that the splint can limit the position of the teaching ruler under the restriction of the limit column 2. Correspondingly, if the required With different sizes, the storage frame, beaker rack and test tube rack can be pulled and disassembled, so that the plug-in column can be separated from the top frame for replacement. When the plug-in column is separated from the top frame, the ball will be first subjected to the force, so that it is squeezed, and then push the squeezing column to squeeze the spring three, so as to smoothly disassemble. When installing, the corresponding ball is also squeezed by the force first, but when the ball is aligned with the reserved slot of the top frame, the corresponding magnet two can jointly push the squeezing column to drive the ball to snap into the top frame through the force generated by the repulsion between it and the magnet one and the force generated by the elastic potential energy of the squeezing column, so as to realize the rapid replacement of the storage frame, beaker rack and test tube rack. Moreover, when the equipment is dragged and displaced, if it encounters an uneven road surface at the bottom and generates vibration, the corresponding vibration force generated will be transmitted to the connecting plate position on the bottom side through the fixed plate position connected to the cylinder, and then the distance between the pressure blocks on both sides of the driving box will be reduced to exert force on damper 1, so that damper 1 can perform the first force buffering and shock absorption. When the distance between the pressure blocks changes, the corresponding inclination angle of the connecting rod will also change, so that the connecting rod can allow the slider to slide in the fixed frame through the docking shaft, so as to perform the second shock absorption through damper 2, thereby reducing the risk of damage to the teaching experimental equipment caused by vibration as much as possible.

[0024] The present invention provides a transport device for teaching equipment that facilitates the use of teaching tools.

[0025] Beneficial effects:

[0026] 1. Through various stable designs, the present invention ensures that teaching equipment is stable and immovable during adjustment and placement by means of components such as limit posts, clamping plates, and springs. Whether adjusting the height of the partition or placing experimental equipment, the device can provide a reliable fixing effect, preventing the equipment from sliding or shifting during the experiment, and ensuring the safety and accuracy of the experimental operation.

[0027] 2. By designing the storage frame, beaker rack, and test tube rack of the device as detachable and quickly replaceable modules, the installation and disassembly of components can be achieved with simple operations. This flexibility enables the device to adapt to different experimental requirements, facilitating users to configure according to the requirements of specific experimental equipment, and improving the efficiency and convenience of experimental teaching.

[0028] 3. Through the design of a dual shock absorption system, the present invention uses damper 1 and damper 2 to absorb and buffer vibrations in stages, significantly reducing the vibration force caused by uneven roads during the dragging process of the device. This shock absorption design effectively protects the teaching experimental equipment, prevents damage caused by vibrations, and ensures the safety and stability of the device.

Detailed implementation manner

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment:

[0041] Please refer to the attached Figure 1 - attached Figure 4 , the embodiment of the present invention provides a handling device for facilitating the access of teaching aids for teaching equipment, including:

[0042] The chassis 1 is provided with cylinders 2 stacked left and right on its top;

[0043] The placement mechanism 4 is installed on the top of the chassis 1 and is used for placing teaching experiment equipment. A top frame 3 is installed at the bottom of the placement mechanism 4;

[0044] The multi-functional mechanism 5 is arranged around the top frame 3 and is used for placing different teaching experiment auxiliary tools;

[0045] The shock absorption mechanism 6 is installed between the cylinder 2 and the placement mechanism 4 and is used for reducing the influence of vibration on the experimental teaching equipment during handling;

[0046] The quick-release mechanism 7 is embedded inside the top frame 3 and is used for quickly installing and docking all components of the multi-functional mechanism 5;

[0047] The placing mechanism 4 includes a first partition plate 41 which slides within the top frame 3. A second partition plate 45 is installed on one side of the first partition plate 41. A push plate 46 slides within the second partition plate 45. A first limiting post 47 slides within the push plate 46. A bolt 42 is threadedly connected within the first partition plate 41. A knob 43 is fixed to the top end of the bolt 42. A rubber pad 44 is fixed to the bottom end of the bolt 42. The rubber pad 44 is fitted within the first partition plate 41. A first spring 48 is sleeved on the outer wall of the first limiting post 47. One end of the first spring 48 is fixed within the second partition plate 45, and the other end of the first spring 48 is installed within the push plate 46.

[0048] Specifically, during the placement process of the experimental teaching equipment, the design of this equipment allows users to flexibly adjust the positions of the first partition plate 41 and the knob 43 according to different experimental requirements, so as to obtain the best placement effect when placing equipment such as chemical experiment alcohol lamps and physical optical imaging equipment. First, when the user needs to adjust the position of the first partition plate 41, the knob 43 needs to be operated first. The knob 43 rotates through the bolt 42 connected to it, and then drives the rubber pad 44 located at the bottom of the first partition plate 41. At this time, the rubber pad 44 gradually disengages from the fitting state with the top frame 3, eliminating the originally existing frictional force. This process makes the first partition plate 41 in a state where it can move freely. During the movement of the first partition plate 41, the push plate 46 is pushed due to the sliding extrusion of the second partition plate 45. The first limiting post 47 sliding within the push plate 46 plays a key role in this process. Through its limiting effect, it prevents the excessive movement of the push plate 46. When the first limiting post 47 is squeezed, through its own reaction force, it ensures the stability of the knob 43 and prevents the position of the knob 43 from shifting during the adjustment process, thus maintaining the smoothness and accuracy of the entire operation process. When the first partition plate 41 moves to the predetermined position, the user turns the knob 43 again. At this time, the bolt 42 drives the rubber pad 44 to fit tightly with the top frame 3 again. Through the frictional force generated between the rubber pad 44 and the top frame 3, the position of the first partition plate 41 is firmly fixed. At the same time, the position of the knob 43 is further fixed by the squeezing force exerted by the first spring 48, so that the entire device obtains extremely high stability and reliability under the combined action of multiple points. Through the above operations, users can flexibly adjust the configuration of the equipment according to experimental requirements to ensure the stable placement of various experimental equipment. This process not only effectively improves the convenience and safety of experimental operations, but also ensures the stability and accuracy of experimental equipment during use, which helps the accuracy and repeatability of experimental results. Therefore, this equipment shows extremely excellent performance and versatility in practical applications, providing a reliable guarantee for the experimental teaching process.

[0049] Please refer to Appendix Figure 1 、Appendix Figure 2 and Appendix Figure 6, the multi-functional mechanism 5 includes a storage frame 51, which is installed on the front and rear sides of the top frame 3 and is symmetrically distributed up and down. A beaker rack 52 is fixed on the left side of the top frame 3. A test tube rack 54 is arranged at the top of the beaker rack 52. The test tube rack 54 is installed on the left side of the top frame 3. A ruler rack 53 is installed on the right side of the top frame 3. A second limiting post 55 slides inside the ruler rack 53. A second spring 56 is sleeved on the outer wall of the second limiting post 55. One end of the second spring 56 is fixed inside the ruler rack 53. The other end of the second spring 56 is fixed with a clamping plate 57. One side of the clamping plate 57 is connected to one end of the second spring 56. The other end of the second limiting post 55 is fixed with a limiting plate 58.

[0050] Specifically, when using this device, for experimental equipment with special shapes or sizes that are not easily placed directly, such as test tubes or beakers, the device provides specially designed beaker racks 52 and test tube racks 54. These racks have reserved fitting holes, enabling test tubes and beakers of various specifications to be securely fixed in their respective positions, avoiding the risk of tipping or slipping during experimental operations. The advantage of this design is that it not only enhances the safety of experimental operations but also ensures the neatness and orderliness of the experimental equipment during storage, providing important support for the standardized management of the teaching environment. In addition, the device is equipped with a storage frame 51, which is designed to be symmetrically distributed vertically and can be used to place various small devices or items. For example, experimental reagent bottles, burettes, or other auxiliary tools in chemical teaching can be conveniently placed in the storage frame 51. This design not only makes full use of the space but also effectively classifies and manages the experimental materials, avoiding the situation of decreased experimental efficiency or missing equipment caused by messy item placement. By centrally placing different types of teaching utensils, the storage frame 51 saves a large amount of time for experimental preparation and cleanup work and improves the smoothness of the teaching process. In physics teaching experiments, teaching rulers of different types and sizes are often indispensable tools. The device is specially designed with a ruler rack 53 for storing and fixing these rulers. The teaching ruler can be placed at the position of the clamping plate 57 through a simple operation. Under the pushing action of the second spring 56, the clamping plate 57 will adaptively adjust according to the width and thickness of the ruler. Under the limitation of the second limit post 55, the clamping plate 57 can firmly fix the teaching ruler in place, preventing the ruler from loosening or shifting during use. For teaching rulers of different sizes, the design of the device also takes into account the need for flexible adaptation. Whether it is a narrow steel ruler or a wide wooden ruler, the combination of the second spring 56 and the clamping plate 57 can provide sufficient elasticity and stability to ensure that the teaching ruler can maintain its preset position whether it is placed or taken out. This precise design not only improves the applicability and diversity of the device but also further enhances the management and operation convenience of various experimental equipment during the teaching process. Overall, through a variety of carefully designed components, such as beaker racks 52, test tube racks 54, storage frames 51, and ruler racks 53, this device realizes the efficient management and stable placement of various teaching experimental equipment. These designs not only consider the characteristics of different experimental materials and tools but also are specifically optimized for their storage needs, greatly enhancing the safety, convenience, and operation efficiency of the experimental teaching process. The versatility and flexibility of this device can meet the diverse needs in different experimental scenarios and provide strong guarantee for the smooth progress of teaching work.

[0051] Please refer to the attached Figure 5 and the attached Figure 9, the shock absorption mechanism 6 includes connecting plates 61 which are symmetrically distributed up and down. The upper connecting plate 61 is fixed to the bottom of the first partition plate 41, and the lower connecting plate 61 is fixed to the fixed plate. A docking frame 62 is installed on one side of each connecting plate 61. A connecting rod 63 is rotatably arranged inside the docking frame 62. A docking shaft 64 is rotatably arranged at one end of each connecting rod 63. A slider 65 is connected between the connecting rods 63 through the docking shaft 64. A counter-pressure block 66 is fixed to one side of each connecting plate 61. A docking frame 68 is arranged between the counter-pressure blocks 66. Fixed frames 69 are installed on both sides of the docking frame 68. The slider 65 slides inside the fixed frame 69. A first damper 67 is arranged between the counter-pressure blocks 66 and is used for the first shock absorption and buffering operation. The output end of the first damper 67 is fixed to the bottom end of the upper counter-pressure block 66. A second damper 610 is arranged inside the fixed frame 69 and is used for the second shock absorption and buffering operation. The output end of the second damper 610 is fixedly connected to one side of the slider 65. The output end of the cylinder 2 is connected to the shock absorption mechanism 6 through the fixed plate.

[0052] Specifically, when the equipment encounters vibrations caused by uneven road surfaces, the vibration force is first transmitted through the cylinder 2 to the connected fixed plate. The fixed plate effectively transmits the vibration force to the position of the bottom connecting plate 61, thereby affecting the activation of the entire shock absorption system. At this time, the vibration force causes the connecting plate 61 to start applying force to both sides, gradually reducing the distance between the counter-pressure blocks 66 located at both ends of the connecting plate 61. As the distance between the counter-pressure blocks 66 decreases, the first damper 67 located between the counter-pressure blocks 66 begins to be squeezed, thereby initiating the first buffer shock absorption; during this process, the first damper 67 gradually consumes a part of the externally transmitted vibration force through the elastic elements and damping media inside it, thereby achieving a preliminary shock absorption effect. This primary buffering effect can significantly reduce the direct impact of the vibration force on the teaching equipment inside the equipment, reduce the risks caused by vibrations, and ensure the stability of the equipment during dragging; at the same time, when the distance between the counter-pressure blocks 66 changes, the connected connecting rod 63 will also correspondingly change the inclination angle. This inclination of the connecting rod 63 changes its relative position with respect to the docking shaft 64, thereby causing the slider 65 to slide inside the fixed frame 69. The sliding of the slider 65 not only further disperses the vibration force but also creates conditions for the second shock absorption and buffering; during the sliding process of the slider 65, the second damper 610 is activated accordingly. The second damper 610 further absorbs and consumes the remaining vibration force through its internal high-efficiency damping device. This process provides a higher level of shock absorption protection for the entire equipment, ensuring that even under relatively severe vibration conditions, the teaching experiment equipment can remain stable and undamaged.

[0053] Please refer to the appendix Figure 7 and the appendix Figure 8The quick release mechanism 7 includes a plug post 71, which is installed on one side of the storage frame 51. A spring three 72 is arranged inside the plug post 71. One end of the spring three 72 is fixed in the plug post 71. An extrusion post 73 is fixed to the other end of the spring three 72. A round ball 74 is arranged inside the extrusion post 73. A magnet one 75 is installed on the outer wall of the extrusion post 73. A magnet two 76 is installed inside the plug post 71. The magnet one 75 and the magnet two 76 repel each other magnetically.

[0054] Specifically, when it is necessary to disassemble the storage frame 51, beaker rack 52 or test tube rack 54, the user can pull these components to separate the connected pins 71 from the internal structure of the top frame 3. During this process, the ball 74 will first be subjected to the external force and squeezed into the interior of the pin 71. This squeezing action then pushes the squeezing column 73 to compress the internal spring three 72. The compression of the spring three 72 provides the necessary buffer and support for the entire disassembly process, ensuring that the pin 71 can be smoothly separated from the top frame 3, thereby achieving easy disassembly of the components. The entire disassembly process is smooth and smooth, thanks to the ingenious application of mechanical principles in the design. By compressing the spring three 72 to buffer and adapt to external forces, the equipment not only reduces the wear on components during the disassembly process, but also improves the comfort and safety of operation. When installing or testing tube rack 54, ball 74 will also be squeezed by external force first. However, during the installation process, when ball 74 is aligned with the reserved slot of top frame 3, the situation changes. At this time, the magnetic repulsion between magnet 2 76 and magnet 1 75 begins to play a role, further pushing extrusion column 73 and ball 74 to move toward the slot of top frame 3. This magnetic repulsion is combined with the driving force of extrusion column 73 under the elastic potential energy of spring three 72, ensuring that ball 74 can be smoothly engaged with the inside of top frame 3. This design not only makes the installation process quick and stable, but also ensures the firmness after installation through the combination of magnetic force and elastic potential energy. After installation, storage frame 51, beaker rack 52 and test tube rack 54 can remain stable in top frame 3 and will not loosen or fall off due to external force, ensuring the safety and reliability of experimental teaching equipment.
