Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and in particular to an experimental table with a structure to prevent experimental vessels from tipping over. Background Technology

[0002] In daily laboratory operations, the workbench is a key piece of equipment that supports core experimental steps such as reagent preparation, sample analysis, and reaction observation. Whether it is storing fragile glass test tubes or beakers, or placing vessels containing corrosive reagents or high-temperature solutions, its stability is directly related to the physical safety of the experimental vessels and the accuracy of experimental data. Even a slight shaking of the workbench may cause the vessels to tip over or the reagents to leak, which not only causes the loss of experimental materials but may also lead to safety accidents and interfere with the results of precision operations such as titration and weighing.

[0003] Most laboratory benches handle laboratory equipment in two ways: one is to simply provide a flat work surface for placing the equipment directly, which easily leads to the tipping over of fragile items such as glass test tubes and beakers; the other is to add structures to secure the equipment, but each time the equipment is taken out or placed, the securing parts need to be repeatedly disassembled, resulting in low operational efficiency. Furthermore, existing laboratory benches generally have the problem of difficulty in balancing mobility and fixation, and are easily affected by external forces, leading to displacement. Utility Model Content

[0004] In the existing technology, most laboratory benches handle laboratory equipment in two ways: one is to simply provide a flat work surface for placing the equipment directly, which easily leads to the tipping of fragile items such as glass test tubes and beakers; the other is to add a structure to fix the equipment, but this requires repeated disassembly and reassembly of the fixing parts each time the equipment is picked up or placed, resulting in low operational efficiency. Furthermore, existing laboratory benches generally suffer from the technical problem of difficulty in balancing movement and fixation, and are susceptible to displacement due to external forces. This utility model provides a laboratory bench with a structure to prevent laboratory equipment from tipping over.

[0005] The technical solution adopted by this utility model is: an experimental table with an anti-tipping structure for experimental vessels, including a base and an experimental table body. The experimental table body is installed on the base. Four casters arranged in a rectangular array are fixedly installed on the bottom of the base. A placement component for placing experimental vessels is installed on one side of the experimental table body. The placement component includes a placement frame fixedly installed on one side of the experimental table body. Fixing components for fixing the experimental table body are installed on both sides of the base. A shock-absorbing component for damping the experimental table body is installed on the top of the base. The placement component enables convenient handling of experimental vessels while ensuring stable placement, taking into account both operational efficiency and anti-tipping requirements. The fixing component can achieve stable fixation of the experimental table without manual effort, improving the reliability of fixation and ease of operation. The shock-absorbing component can effectively reduce the impact of vibration on the stability of the experimental vessels.

[0006] Furthermore, the upper surface of the placement frame of the placement component has multiple placement slots arranged in a linear array. A sliding plate is slidably connected inside each of the placement slots. A connecting plate is fixedly installed on one side of each sliding plate, passing through one side of the placement slot and slidably connected inside the placement frame. Two symmetrical sliding rods are fixedly installed above the connecting plate, both of which pass through the upper surface of the placement frame and are slidably connected to it. A pull rod is fixedly installed at the top of each sliding rod, and a telescopic spring is fixedly installed on the surface of each sliding rod. Through the linkage design of the sliding rods and the telescopic springs, convenient handling of experimental instruments can be achieved, improving operational efficiency and placement reliability.

[0007] Furthermore, silicone pads are fixedly installed on the inner wall of the placement groove and the upper surface of the sliding plate, which can prevent the vessel from being damaged by collision.

[0008] Furthermore, the fixing assembly includes a bidirectional motor fixedly mounted on the back of the base. Rotating rods are fixedly mounted on both output ends of the bidirectional motor. A first bevel gear is fixedly mounted on one end of each of the two rotating rods. A second bevel gear meshes with the surfaces of both first bevel gears. A threaded rod is fixedly mounted on one side of each of the two second bevel gears. The two threaded rods are rotatably connected to both sides of the base via bearing seats. Two moving blocks with opposite threads are threadedly connected to the surfaces of the two threaded rods. A connecting rod is hinged below each moving block. A support plate is hinged to the bottom of the two connecting rods on the same side, and the bottoms of the two connecting rods are respectively hinged to both sides of the support plate. Through the transmission mechanism of the bidirectional motor and the first and second bevel gears, the support plate can be lowered synchronously to fix the experimental platform body, improving its stability.

[0009] Furthermore, two symmetrical limiting rods are fixedly installed above the support plate. All of the limiting rods pass through the base and are slidably connected to the base. By using the limiting rods that pass through the base, the lateral sway of the support plate can be restricted, ensuring that it moves in the vertical direction.

[0010] Furthermore, an anti-slip pad is fixedly installed at the bottom of the support plate. The anti-slip pad can increase the friction with the ground, prevent the experimental platform from shifting after it is fixed, and improve its stability.

[0011] Furthermore, the shock absorption assembly includes sleeves and a first damping spring. The sleeves are arranged in a rectangular array and fixedly installed above the base. The tops of the four sleeves are fixedly connected to the bottom of the experimental platform body. The first damping spring is fixedly installed inside the four sleeves. Through the rectangular array of sleeves and the first damping spring, vibration can be efficiently absorbed, reducing the impact of up-and-down shaking on the vessel.

[0012] Furthermore, the shock absorption assembly also includes a mounting groove formed on the surface of the base. A fixing rod is fixedly installed inside the mounting groove. Two symmetrical sliding blocks are slidably connected to the surface of the fixing rod. A hinge rod is hinged above each of the two sliding blocks. The tops of the two hinge rods are respectively hinged to the bottom sides of the experimental platform body. A second damping spring is fixedly installed between the two sliding blocks. The shock absorption effect is further improved by the cooperation between the sliding blocks and the second damping spring.

[0013] The beneficial effects of this utility model are: 1. This utility model enables convenient handling of experimental vessels while ensuring stable placement through the placement component, balancing operational efficiency and anti-tipping requirements. It solves the problems of most laboratory benches that handle experimental vessels in two ways: one is to simply provide a flat operating table for placing the vessels directly, which easily leads to the tipping of fragile vessels such as glass test tubes and beakers; the other is to add a structure to fix the vessels, but the fixing parts need to be repeatedly disassembled and reassembled each time the vessels are picked up or placed, resulting in low operational efficiency.

[0014] 2. This utility model can achieve stable fixation of the experimental platform without the need for manual labor by using a fixing component, thereby improving the reliability of fixation and the convenience of operation. It solves the problem that existing experimental platforms are still generally difficult to balance movement and fixation, and are easily affected by external forces, resulting in displacement.

[0015] 3. By incorporating shock-absorbing components, this invention can effectively reduce the impact of vibration on the stability of experimental apparatus, thereby improving its stability. Attached Figure Description

[0020] The following is in conjunction with the appendix Figures 1-5 The present invention will be further described below.

[0021] In order to solve the problems existing in the background technology, this application proposes the following technical solution: an experimental platform with a structure to prevent experimental vessels from tipping over.

[0022] The specific technical solution includes a base 1 and an experimental platform body 2. The experimental platform body 2 is installed on top of the base 1. Four casters 3 arranged in a rectangular array are fixedly installed on the bottom of the base 1. A placement component 4 for placing experimental vessels is installed on one side of the experimental platform body 2. The placement component 4 includes a placement frame 401 fixedly installed on one side of the experimental platform body 2. Fixing components 5 for fixing the experimental platform body 2 are installed on both sides of the base 1. A shock-absorbing component 6 for damping and buffering the experimental platform body 2 is installed on top of the base 1. The placement component 4 can make it easy to pick up and put down experimental vessels while ensuring stable placement, taking into account both operational efficiency and anti-tipping requirements. The fixing component 5 can achieve stable fixation of the experimental platform without manual operation, improving the reliability of fixation and ease of operation. The shock-absorbing component 6 can effectively reduce the impact of vibration on the stability of the experimental vessels.

[0023] Reference Figure 1 and Figure 2 As shown, the upper surface of the placement frame 401 of the placement component 4 has multiple placement slots 402 arranged in a linear array. Sliding plates 403 are slidably connected inside the placement slots 402. A connecting plate 404 is fixedly installed on one side of the sliding plate 403, passing through one side of the placement slot 402 and slidably connected inside the placement frame 401. Two symmetrical sliding rods 405 are fixedly installed above the connecting plate 404. Both sliding rods 405 pass through the upper surface of the placement frame 401 and are slidably connected to the placement frame 401. Pull rods 406 are fixedly installed on the top of the two sliding rods 405. Telescopic springs 407 are fixedly installed on the surface of the two sliding rods 405. Silicone pads 408 are fixedly installed on the inner wall of the placement slots 402 and the upper surface of the sliding plate 403. Test tubes, beakers, and other laboratory instruments are placed into the linear array placement slots 402 on the placement frame 401. The silicone pads 408 on the inner wall of the placement slots 402 adhere to the outer wall of the instruments, achieving containment and positioning. Pulling the pull rod 406 of the placement component 4 upward causes the two sliding rods 405 fixed thereto to slide upward along the upper surface of the placement frame 401. The connecting plate 404 connected to the bottom of the sliding rods 405 rises simultaneously, thereby pulling the sliding plate 403 fixed on one side of the connecting plate 404 upward within the placement slots 402, making it easy to retrieve the instruments. At this time, the telescopic spring 407 on the surface of the sliding rod 405 is compressed. Releasing the pull rod 406 releases the elastic force of the telescopic spring 407, pushing the sliding rod 405, connecting plate 404, and sliding plate 403 downward as a whole, making it convenient to place the instruments next time.

[0024] Reference Figure 1 , Figure 3 and Figure 4As shown, the fixing assembly 5 includes a bidirectional motor 501 fixedly installed on the back of the base 1. Rotating rods 502 are fixedly installed on both output ends of the bidirectional motor 501. A first bevel gear 503 is fixedly installed on one end of each of the two rotating rods 502. A second bevel gear 504 meshes with the surfaces of both first bevel gears 503. A threaded rod 505 is fixedly installed on one side of each of the two second bevel gears 504. The two threaded rods 505 are rotatably connected to both sides of the base 1 via bearing seats. Two opposing threaded moving blocks 506 are threadedly connected to the surfaces of both threaded rods 505. A connecting rod 507 is hinged below each moving block 506. A support plate 508 is hinged to the bottom of the two connecting rods 507 on the same side, and the bottoms of the two connecting rods 507 are respectively hinged to both sides of the support plate 508. Two symmetrical limiting rods 509 are fixedly installed above the support plate 508. Multiple limiting rods 509 penetrate the base 1 and are connected to... The base 1 is slidably connected, and the bottom of the support plate 508 is fixedly equipped with an anti-slip pad 510. The bidirectional motor 501 synchronously drives the rotating rod 502 to rotate through its two output ends. The first bevel gear 503 at the end of the rotating rod 502 rotates accordingly and drives the second bevel gear 504 to rotate through gear meshing. The power is then transmitted to the threaded rod 505 fixedly connected to the second bevel gear 504. Because the threads of the two moving blocks 506 are set in opposite directions, the two moving blocks 506 move in opposite directions. The connecting rod 507 hinged below the moving blocks 506 gradually unfolds as the moving blocks 506 move away, pushing the support plate 508, which is hinged together, to move vertically downward. During this process, the two symmetrical limiting rods 509 above the support plate 508 pass through the base 1 and slide along it, strictly limiting the lateral displacement of the support plate 508 and avoiding left and right swaying. The experimental platform body 2 can be fixed when the anti-slip pad 510 at the bottom of the support plate 508 is in close contact with the ground.

[0025] Reference Figure 1 and Figure 5As shown, the shock absorption assembly 6 includes sleeves 601 and first damping springs 602. Four sleeves 601 are arranged in a rectangular array and fixedly installed above the base 1. The tops of all four sleeves 601 are fixedly connected to the bottom of the experimental platform body 2. The first damping springs 602 are fixedly installed inside the four sleeves 601. The shock absorption assembly 6 also includes a mounting groove 603 formed on the surface of the base 1. A fixing rod 604 is fixedly installed inside the mounting groove 603. Two symmetrical sliding blocks 605 are slidably connected to the surface of the fixing rod 604. Each sliding block 605 is hinged to a hinge rod 606. The tops of the two hinge rods 606 are respectively hinged to the bottom sides of the experimental platform body 2. When the experimental platform is subjected to vertical vibration, the first damping spring 602 absorbs the vibration energy through extension and contraction, preventing the experimental platform body 2 from shaking violently up and down. At the same time, the experimental platform body 2 moves downward, pushing the hinge rods 606 on both sides to change their angles, thereby causing the two sliding blocks 605 to slide relative to each other along the fixed rod 604, thereby compressing the second damping spring 607 and further improving the shock absorption effect.

[0026] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview: Test tubes, beakers, and other glassware are placed into the linear array placement slots 402 of the placement frame 401. The silicone pads 408 on the inner wall of the placement slots 402 adhere to the outer wall of the glassware for positioning. The experimental platform body 2 is pushed, and the universal wheels 3 arranged in a rectangular array on the bottom of the base 1 are used to move the experimental platform body 2 to the target experimental position. The bidirectional motor 501 on the back of the base 1 is turned on, and its output end drives the rotating rod 502 to rotate, which drives the first bevel gear 503 at the end to mesh with the second bevel gear 504, causing the threaded rod 505 to rotate synchronously. The moving blocks 506 with opposite threads on the surface of the threaded rod 505 move away from each other, pushing the lower hinged connecting rod 507 to unfold, causing the support plate 508, which is hinged together, to move vertically downward. The limiting rod 509 above the support plate 508 slides along the base 1 to limit lateral displacement. When the anti-slip pad 510 at the bottom of the support plate 508 is in close contact with the ground, the bidirectional motor 501 is turned off, and the placement frame 401 is pulled upward. 1. The top pull rod 406 drives the sliding rod 405 to move up along the upper surface of the placement frame 401. Through the connecting plate 404, the sliding plate 403 in the placement slot 402 is pulled up. At this time, the telescopic spring 407 on the surface of the sliding rod 405 is compressed, and the vessel can be taken out for testing. Then, the pull rod 406 is released, the telescopic spring 407 releases its elasticity, and pushes the sliding rod 405, the connecting plate 404 and the sliding plate 403 back to their original positions, which facilitates the subsequent placement of the vessel. When the experimental table is subjected to vertical vibrations such as ground bumps or the placement of objects, the first damping spring 602 in the sleeve 601 between the base 1 and the experimental table body 2 absorbs the vibration energy through telescopic deformation, reducing the up-and-down swaying of the experimental table body 2. At the same time, the experimental table body 2 pushes the hinge rods 606 on both sides of the bottom to change angle, causing the sliding block 605 on the fixed rod 604 in the mounting slot 603 to slide relative to each other, compressing the second damping spring 607 to further absorb energy and enhance the shock absorption effect.
