Description

Technical Field

[0001] The invention relates to the technical field of laboratory screen platform equipment, and in particular to a hidden control screen for laboratory management. Background Art

[0002] When teaching in the laboratory, the lecturer usually demonstrates at the podium and the students demonstrate below. This traditional teaching method relies too much on the students' memory. If the students forget, they need to repeat the demonstration, which is cumbersome. Therefore, the current laboratories have gradually demonstrated and displayed to students through screens.

[0003] In existing teaching laboratories, there is usually only one large display screen to replace the traditional lecture table. Students can step by step demonstrate and practice by watching the operating steps on the display screen. When students forget or want to focus on a step, they only need to operate the display screen to fast forward or rewind. However, the learning progress of students cannot be guaranteed to be completely consistent. Therefore, it is difficult for a single display screen to ensure the learning progress of each student. In order to ensure the learning progress of each student, each laboratory table needs to be equipped with a small display control screen. During the experiment, the experimental tools also need to occupy a certain area of ​​the laboratory table. Placing a small display control screen will result in insufficient operating space on the surface of the table.

[0004] In order to solve the above problems, a display control screen that can be hidden for use is urgently needed. Now a hidden control screen for laboratory management is proposed. Summary of the invention

[0005] In view of the above-mentioned problems, the present invention provides a hidden control screen for laboratory management, which solves the problem that in existing teaching laboratories, usually only a large display screen replaces the traditional lecture table. Students can gradually perform demonstration exercises by watching the operating steps on the display screen. When students forget or want to focus on a step, they only need to operate the display screen to fast forward or rewind. However, the learning progress of students cannot be guaranteed to be completely consistent. Therefore, it is difficult for a single display screen to ensure the learning progress of each student. In order to ensure the learning progress of each student, each laboratory table needs to be equipped with a small display control screen. During the experiment, the experimental tools also need to occupy a certain area of ​​the laboratory table. Placing a small display control screen will lead to insufficient operating space on the surface of the table.

[0018] In order to make the purpose, technical solution and advantages of the invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] refer to Figures 1 to 11 , a hidden control panel for laboratory management, comprising a control panel 5, characterized in that: it also comprises an n-type laboratory table 1, a vertical plate 14, a shielding plate 2, a storage box 7, an L-shaped fixed plate 11, an n-type laboratory chair 8, a movable rod 6, an operating mechanism, a tilting mechanism, a flipping mechanism, a first sliding mechanism, and a second sliding mechanism; Two vertical plates 14 are fixedly installed between the two vertical plates of the n-type experimental table 1, and the top walls of the two vertical plates 14 are respectively fixedly connected to the bottom walls of the horizontal plate of the n-type experimental table 1. The n-type experimental table 1 provides an experimental platform for users; A first gap is left between the two vertical plates 14, and a movable rod 6 is detachably installed in the first gap. The first gap between the two vertical plates 14 is used to hide the control panel 5; The movable rod 6 is driven to slide by an operating mechanism, and the operating mechanism is arranged inside the first gap. The movable rod 6 drives the control screen 5 to move and hide in the first gap, or extends out of the first gap to move the control screen 5 onto the desktop; The control screen 5 is rotatably arranged at the front side of the upper end of the movable rod 6. The control screen 5 is driven to tilt by the tilting mechanism. The control screen 5 is detachably arranged in the first gap. When the control screen 5 is fully extended out of the first gap and is located above the n-shaped experimental table 1, the tilting mechanism will synchronously tilt the control screen 5 forward by a certain angle to provide a better viewing angle for the user. The movable rod 6 is driven by the tilting mechanism to work, and the movable rod 6 is slidably arranged between the horizontal plate of the n-shaped experimental table 1; A shielding plate 2 is movably installed behind the movable rod 6, and the left and right side walls of the shielding plate 2 are respectively rotatably arranged on the outer walls of the two vertical plates of the n-shaped experimental table 1; The shielding plate 2 is driven to rotate by the flipping mechanism. The shielding plate 2 can be flipped up and down under the drive of the flipping mechanism. When the movable rod 6 drives the control screen 5 to fully move into the first gap, the shielding plate 2 just rotates downward and completely covers the control screen 5 to achieve hiding. The flipping mechanism is driven to work by the operating mechanism; A horizontal plate of the L-shaped fixing plate 11 is vertically mounted on the left side of the front wall of the vertical plate 14 located at the front side; A storage box 7 is movably installed above the horizontal plate of the L-shaped fixed plate 11. The bottom wall of the storage box 7 is detachably in contact with the upper end of the horizontal plate of the L-shaped fixed plate 11. The storage box 7 is used to store some experimental tools or experimental drugs. In chemical experiments, these experimental drugs are usually placed in a drug box, which is inconvenient to take out during the experiment. In addition, some drugs have pungent odors and cannot be placed outside. Therefore, the storage box 7 provides a closed space that can isolate the odor for such experimental drugs. When the experiment is needed, the storage box 7 will be extended out of the table with these drugs. When the experiment is finished, the storage box 7 will also be hidden behind the vertical plate of the L-shaped fixed plate 11. The front wall of the storage box 7 is movably arranged on the rear wall of the vertical plate of the L-shaped fixed plate 11, and the storage box 7 is slidably arranged between the horizontal plate of the n-shaped laboratory table 1; The storage box 7 is driven to slide by the first sliding mechanism; The first sliding mechanism is driven to work by the flipping mechanism; An n-shaped experimental chair 8 is movably installed on the right side of the storage box 7, and the horizontal board of the n-shaped experimental chair 8 is movably arranged under the horizontal board of the n-shaped experimental table 1; The n-type laboratory chair 8 is driven to slide by the second sliding mechanism, and the second sliding mechanism will work synchronously with the operation of the flip mechanism. When an experiment is needed, the n-type laboratory chair 8 will slide out of the laboratory table driven by the second sliding mechanism. When the experiment is finished, it can be controlled to slide back into the laboratory table to avoid occupying the laboratory floor space; The storage box 7 drives the second sliding mechanism to work through movement.

[0021] The tilting mechanism comprises a first T-shaped slider 24, a first connecting rod 23, and a return spring; A first rectangular through slot 102 is provided on the horizontal plate of the n-type experimental table 1, and the control panel 5 and the first rectangular through slot 102 are detachably and movably arranged to penetrate each other; Two first T-shaped slide grooves 501 are respectively provided on the rear wall of the outer shell of the control panel 5, and two cross plates of the first T-shaped slide blocks 24 are respectively slidably installed in the two first T-shaped slide grooves 501; First connecting frames are fixedly mounted on the vertical plates of the two first T-shaped sliding blocks 24, and first ends of the first connecting rods 23 are rotatably mounted in the two first connecting frames. The first connecting shafts are respectively installed on the two side walls of the movable rod 6; The second ends of the two first connecting rods 23 are rotatably sleeved on the outer side walls of the two first connecting shafts respectively; A rectangular groove 1021 is provided on the rear wall of the first rectangular through slot 102; The movable rod 6 is movably installed in the rectangular groove 1021; A second gap is left between the two side walls of the movable rod 6 and the left and right side walls of the rectangular groove 1021 respectively; The two first connecting rods 23 are respectively detachably and movably arranged to penetrate between the two second gaps; The two first T-shaped slide blocks 24 are respectively connected to the top wall of the first T-shaped slide groove 501 matched therewith by a return spring. Figure 5 Since the control panel 5 is rotatably connected to the upper end of the movable rod 6, when the control panel 5 completely slides out of the first rectangular through slot 102 and is placed above the horizontal plate of the n-shaped experimental table 1, since the two first T-shaped sliders 24 are still above the two first T-shaped slide slots 501 at this time, the first T-shaped sliders 24 located inside the two first T-shaped slide slots 501 will begin to slide downward under the action of the reset spring. In the process of sliding downward, the two first T-shaped sliders 24 will respectively drive the first connecting rods 23 on both sides to start deflecting downward. When the angle between the two first connecting rods 23 and the control panel 5 begins to decrease during the downward deflection, the control panel 5 begins to flip upward at a certain angle until the two first connecting rods 23 are perpendicular to the rear wall of the control panel 5, and the reset spring stops resetting, and the control panel can be fixed at this angle.

[0022] The operating mechanism comprises a second T-shaped slider 601, a bidirectional threaded rod 15, a threaded slider 17, a second connecting frame 602, a third connecting frame 1701, a crank handle 20, a first sprocket 16, a second sprocket 19, and a second connecting rod 18; The vertical rod of the second T-shaped slider 601 is installed on the rear wall of the movable rod 6; A second T-shaped slide groove 1022 is provided on the rear wall of the rectangular groove 1021, and the cross bar of the second T-shaped slide block 601 is slidably installed in the second T-shaped slide groove 1022; The second connecting frames 602 are respectively installed below the two first connecting shafts, and the two second connecting frames 602 are respectively fixed on the left and right side walls of the movable rod 6; The two second connecting frames 602 are both movably arranged under the horizontal plate of the n-shaped experimental table 1; The first ends of the second connecting rods 18 are rotatably mounted in the two second connecting frames 602 respectively; A same bidirectional threaded rod 15 is rotatably installed between the lower ends of the two vertical plates of the n-type experimental table 1, and the bidirectional threaded rod 15 is arranged in the first gap; Threaded sliders 17 are respectively threadedly installed on both sides of the bidirectional threaded rod 15, and third connecting frames 1701 are respectively fixedly installed on the upper ends of the two threaded sliders 17; The second ends of the two second connecting rods 18 are rotatably disposed in the two third connecting frames 1701 respectively; The left end of the bidirectional threaded rod 15 rotates through the left vertical plate of the n-shaped laboratory table 1 and is fixedly mounted with a first sprocket 16; A second sprocket 19 is installed on one side of the first sprocket 16, and the second sprocket 19 is rotatably arranged on the outer wall of the left vertical plate of the n-shaped laboratory table 1 through the first rotating shaft; The diameter of the first sprocket 16 is smaller than the diameter of the second sprocket 19, and the first sprocket 16 and the second sprocket 19 are sleeved and meshed with the same chain on their outer sides; A crank handle 20 is fixedly mounted on the outer end of the first rotating shaft, and the crank handle 20 is arranged on the outer side of the second sprocket 19; The first rotating shaft drives the flipping mechanism to work by rotating, Figure 3 , the user turns the crank 20, causing the crank 20 to start rotating, and the second sprocket 19 coaxial with the crank 20 also starts rotating synchronously, and the second sprocket 19 transmits the rotational driving force to the first sprocket 16 through the chain, causing the first sprocket 16 to start rotating. Since the diameter of the second sprocket 19 is larger than the diameter of the first sprocket 16, the first sprocket 16 rotates at a higher speed and drives the bidirectional threaded rod 15 coaxially installed therewith to start rotating at a high speed. The two threaded sliders 17 threadedly sleeved on the bidirectional threaded rod 15 are located at the same direction of the thread rotation of the bidirectional threaded rod 15 at this time. The two threaded sliders 17 are at opposite ends, so the two threaded sliders 17 will slide away from each other or towards each other with the high-speed rotation of the two-way threaded rod 15. When the two two-way threaded rods 15 slide towards each other, the two second connecting rods 18 begin to deflect upward. In the process of upward deflection, the two second connecting rods 18 will push the same movable rod 6 to start moving upward, so that the movable rod 6 can drive the control screen 5 to move to the top of the n-type laboratory table 1. The cooperation of the second T-shaped slider 601 and the second T-shaped slide groove 1022 ensures the moving trajectory of the movable rod 6 and ensures that it will not deviate during the sliding process.

[0023] The flipping mechanism comprises a spur gear 21, a rack plate 22, a rectangular slider 4, and a third connecting rod 3; A spur gear 21 is fixedly mounted on the first rotating shaft, and the spur gear 21 is arranged on the inner side of the second sprocket 19; The upper end of the spur gear 21 is meshed with a rack plate 22; The two vertical plates of the n-type experimental table 1 are respectively provided with second rectangular through grooves 101, and rectangular sliding blocks 4 are respectively slidably installed in the two second rectangular through grooves 101; The second connecting shafts are fixedly mounted on the outer side walls of the two rectangular sliding blocks 4, and the first ends of the third connecting rods 3 are rotatably mounted on the outer side walls of the two second connecting shafts. A third connecting shaft is fixedly installed in the middle of the left and right side walls of the shielding plate 2; The second ends of the two third connecting rods 3 are rotatably sleeved on the two third connecting shafts respectively; The lower end of the outer wall of the rectangular sliding block 4 close to the rack plate 22 is fixedly connected to the middle part of the upper end of the rack plate 22 through a connecting piece; The rectangular slider 4 close to the rack plate 22 drives the first sliding mechanism to work by sliding. When the second sprocket 19 rotates, it will also synchronously drive the spur gear 21 coaxially mounted therewith to start rotating. During the rotation process, the spur gear 21 drives the rack plate 22 meshed with it to start sliding. The rectangular slider 4 fixedly mounted on the rack plate 22 also has the sliding ability at this time. The cooperation between the rectangular slider 4 and the second rectangular through groove 101 determines the sliding trajectory of the rack plate 22 and ensures that it will not deviate or fall off during the sliding process. Figure 6 Since the rotation center between the shielding plate 2 and the n-type laboratory table 1 has been determined, when the rectangular slider 4 slides, it will drive the third connecting rod 3 to start deflecting. During the deflection process, the third connecting rod 3 can pull or push the shielding plate 2 to close or open. When the control screen 5 moves upward, the shielding plate 2 gradually flips upward and opens. When the control screen 5 gradually moves downward, the shielding plate 2 gradually flips downward. When the control screen 5 is fully moved to the bottom of the horizontal plate of the n-type laboratory table 1, the shielding plate 2 completely closes the first rectangular through groove 102 to completely hide the control screen 5.

[0024] The first sliding mechanism comprises a cylindrical guide rail 1101 and a fourth connecting rod 27; A second rectangular through hole 103 is provided at the upper end of the horizontal plate of the n-type experimental table 1, and the second rectangular through hole 103 is provided on one side of the first rectangular through groove 102; The storage box 7 is slidably connected to the second rectangular through hole 103; A plurality of guide rails 1101 are installed on the upper end of the horizontal plate of the L-shaped fixing plate 11; The lower end of the storage box 7 is provided with a plurality of circular holes that cooperate with the guide rail 1101; A plurality of guide rails 1101 are slidably disposed in the circular holes matched therewith; A fourth connecting shaft is fixedly mounted on the inner side wall of the rectangular sliding block 4 close to the rack plate 22, and a first end of a fourth connecting rod 27 is rotatably mounted on the outer side wall of the fourth connecting shaft; A fifth connecting shaft is fixedly mounted on the outer side wall of the storage box 7 near the rack plate 22; The second end of the fourth connecting rod 27 is rotatably sleeved on the outer side of the fifth connecting shaft; A third gap is left between the left side wall of the storage box 7 and the left vertical board of the n-shaped experimental table 1; The fourth connecting rod 27 is movably arranged in the third gap, referring to Fig.10When the rectangular slider 4 slides to the left, it will drive the fourth connecting rod 27 to start to deflect upward, and in the process of upward deflection, it will drive the storage box 7 to start to slide upward. Since the cooperation between the cylindrical guide rail 1101 and the round hole has determined the sliding trajectory of the storage box 7, the storage box 7 can only slide upward under the drive of the fourth connecting rod 27, and finally pass through the second rectangular through hole 103 and move to the top of the horizontal plate of the n-type laboratory table 1.

[0025] The second sliding mechanism comprises a fifth connecting rod 26, a roller 10, a mounting plate 9, and a rectangular guide rod 12; Rectangular guide rods 12 are fixedly mounted on both sides of the middle of the front wall of the vertical plate 14 at the front side, and the two rectangular guide rods 12 are arranged parallel to each other; First rectangular through holes cooperating with the rectangular guide rods 12 are respectively installed on the rear walls of the two vertical plates of the n-type experimental chair 8; The two rectangular guide rods 12 are both slidably disposed in the two first rectangular through holes; A mounting plate 9 is fixedly mounted between the two vertical plates of the n-type experimental chair 8; A sixth connecting shaft is fixedly mounted on the outer wall of the mounting plate 9 close to the storage box 7; The first end of the fifth connecting rod 26 is rotatably mounted on the sixth connecting shaft; A seventh connecting shaft is installed on the side wall of the storage box 7 near the n-type experimental chair 8; The second end of the fifth connecting rod 26 is rotatably sleeved on the outer side wall of the seventh connecting shaft; The two mounting plates 9 are provided with rollers 10 rotatably mounted on the lower sides of both ends. Figure 7 When the storage box 7 moves upward, the fifth connecting rod 26 also begins to deflect upward at this time, and gradually tends to be perpendicular to the ground during the upward deflection. Since the sliding trajectory of the n-type laboratory chair 8 has been determined by the cooperation of the two rectangular guide rods 12 and the two first rectangular through holes, the fifth connecting rod 26 begins to drive the n-type laboratory chair 8 to slide outward during the upward deflection. When the fifth connecting rod 26 is perpendicular to the ground, the n-type laboratory chair 8 slides outward to the extreme position, which is convenient for users to use. During the outward sliding process of the n-type laboratory chair 8, the roller 10 rolls on the ground, reducing the friction between the n-type laboratory chair 8 and the ground when it moves.

[0026] A plurality of partition plates 13 are installed in the storage box 7, and the plurality of partition plates 13 can be detachably and slidably arranged on the inner wall of the vertical plate of the L-shaped fixed plate 11; A third rectangular through hole is provided on the vertical plate of the L-shaped fixed plate 11, and a normally closed protective door 25 is movably installed in the third rectangular through hole; An armrest 2501 is installed on the front wall of the normally closed protective door 25. The partition plate 13 is used to classify and hold some experimental instruments or medicines. When it slides out from above the horizontal plate of the n-type laboratory table 1 under the drive of the first sliding mechanism, the partition plate 13 will be completely exposed, which is convenient for users to take items as needed. When the storage box 7 slides downward and completely slides under the horizontal plate of the n-type laboratory table 1, several partition plates 13 are all blocked by the vertical plate of the L-shaped fixed plate 11 to form a closed environment. The normally closed protective door 25 always provides a closed path for the vertical plate of the L-shaped fixed plate 11, providing secondary protection for the irritating drugs in the partition plate 13. At the same time, since the protective door 25 can also be opened to replace the items inside the storage box 7, it is more convenient to use.

[0027] Implementation method of the present invention: When the device is in the initial state, Fig.11 As shown in A, the movable rod 6 with the control panel 5 is completely placed under the horizontal board of the n-type experimental table 1 and between the two vertical boards 14, the shielding board 2 is completely flipped to be parallel to the horizontal board of the n-type experimental table 1 and shields the top of the control panel 5, the n-type experimental chair 8 is placed under the horizontal board of the n-type experimental table 1, and the bottom of the storage box 7 is supported by the horizontal board of the L-shaped fixed board 11 and is located under the horizontal board of the n-type experimental table 1; When it is necessary to do an experiment, the handle 20 is operated, and the movable plate 6 starts to drive the control screen 5 to move up, and the shielding plate 2 starts to flip upward to make room for the control screen 5 to slide out. When the control screen 5 completely slides out of the horizontal plate of the n-type laboratory table 1, it will flip forward a certain angle driven by the tilting mechanism to provide a better viewing angle for the user. At the same time, the n-type laboratory chair 8 slides out of the laboratory table, and the storage box 7 also slides out of the horizontal plate of the n-type laboratory table 1, and the internal partition 13 is completely exposed, and the experimental equipment and experimental drugs on the partition 13 can be conveniently taken out at this time. Fig.11 B can start the experiment; After completing the test, the user needs to apply a backward force to the control screen 5 to compress the reset spring. When the control screen 5 is completely flipped over to be perpendicular to the horizontal plate of the n-type experimental table 1 and can just pass through the first rectangular through groove 102, the handle is turned in the opposite direction. At this time, the control screen 5 slides down to the bottom of the experimental table again driven by the movable rod 6, and the baffle plate 2 blocks and hides the top of it. The storage box 7 and the n-type experimental chair 8 are also moved back to the bottom of the experimental table at this time, which increases the surface space of the experimental table while reducing the footprint of the equipment.

[0028] The first sliding mechanism of the present invention can drive the control screen to move up and down, and during the movement, the control screen can be tilted at a certain angle so that the user has a better viewing angle, and the control screen can be stored between the two vertical plates under the drive of the first sliding mechanism. The flipping mechanism of the present invention flips the shielding plate downward when the control screen is lowered, thereby completely hiding the control screen. The second movable mechanism of the present invention can drive the storage box to be hidden synchronously.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
