Description

Technical Field

[0001] This invention relates to the field of display equipment technology, and in particular to a method for representing interior design drawings and a display device thereof. Background Technology

[0002] In the teaching process, teachers often need to display interior design drawings to facilitate students' learning. Sometimes, multiple interior design drawings need to be displayed at the same time. The existing display devices require manual replacement of the interior design drawings, which wastes a lot of time. If the interior design drawings are laid flat on the table for display, students have to leave their seats and gather around the table where the design drawings are placed in order to see the complete design drawings. At the same time, the existing display devices are not convenient for changing the interior design drawings.

[0003] Solving the aforementioned technical problems is the challenge faced by this invention. Summary of the Invention

[0004] In order to achieve the above-mentioned objectives and address the above-mentioned technical problems, the present invention provides a method for representing interior design drawings and a display device thereof.

[0005] The technical solution includes a rectangular storage box and a rectangular collection box, with a display unit between the rectangular storage box and the rectangular collection box. A foot-operated lifting mechanism is provided below the rectangular storage box. The rectangular storage box contains several linearly arranged picture frames, and the foot-operated lifting mechanism is used to drive the picture frames in the rectangular storage box to rise.

[0007] The pedal lifting mechanism includes a fixed plate, a cylindrical tube fixedly connected to the fixed plate, a lifting column sleeved with the cylindrical tube, a first hinge seat, a second hinge seat, and a third hinge seat fixedly connected to the outer wall of the cylindrical tube, a pedal rod with its inner end hinged to the first hinge seat, a connecting rod with its bottom end hinged to the middle of the pedal rod, and a rotating rod with its outer end hinged to the top of the connecting rod. A first pawl is hinged to the inner end of the rotating rod, the middle of the rotating rod is hinged to the outer side of the second hinge seat, a second pawl is hinged to the third hinge seat, the middle of the second pawl is hinged to the third hinge seat, an extension rod is fixedly connected to the outer end of the second pawl, and a first L-shaped connecting rod is fixedly connected to the side wall of the outer end of the second pawl. One end of the lifting column is fixedly connected to one side wall of the second pawl, and the other end is fixedly connected to a first counterweight. The outer wall of the lifting column is provided with two sets of one-way tooth surfaces. One set of one-way tooth surfaces cooperates with the first pawl to drive the lifting column to move upward. The other set of one-way tooth surfaces cooperates with the second pawl to restrict the lifting column to move downward. The one-way tooth surface set includes several linearly arranged one-way tooth surfaces. The one-way tooth surfaces cooperate with the first pawl and the second pawl respectively. One side wall of the pedal rod is fixedly connected to a second L-shaped connecting rod. One end of the second L-shaped connecting rod is fixedly connected to the outer side wall of the pedal rod, and the other end is fixedly connected to a second counterweight. The outer end of the pedal rod is fixedly connected to a pedal.

[0008] The Geneva mechanism includes a Geneva wheel fixed coaxially with the rotating disk and a dial that cooperates with the Geneva wheel. The Geneva wheel includes four Geneva grooves arranged in a circumferential array and four arc grooves arranged in a circumferential array. The arc grooves and Geneva grooves are arranged alternately. A rotating disk is coaxially fixedly connected to the lower surface of the dial. A cylindrical pin is provided on the rotating disk. The outer wall of the dial cooperates with the arc grooves. The cylindrical pin cooperates with the Geneva grooves. A support frame is provided below the dial for mounting the dial below. A first motor is fixedly connected to the lower surface of the support frame. The output shaft of the first motor is rotatably connected to the support frame and coaxially fixed with the dial.

[0009] The flipping mechanism includes four circumferentially arrayed support rods, which are fixedly connected to the upper surface of the rotating disk. Each support rod has a first rotating rod hinged to one side, and each first rotating rod has two symmetrical second rotating rods hinged to one end. A collection frame is hinged to the end of each of the two second rotating rods away from the first rotating rod. Two symmetrical fixing rods are fixedly connected to one side wall of the collection frame, and one end of each fixing rod is fixedly connected via a connecting shaft, which is rotatably connected to the rotating disk. A groove is provided on one side wall of the collection frame, which mates with the picture frame. A magnetic suction unit is provided on the collection frame for adsorbing the picture frame. The first rotating rods are driven to rotate by a flipping drive component.

[0010] The flipping drive component includes a first linkage gear rotatably connected to the upper surface of the rotating disk, and linkage gear assemblies corresponding one-to-one with the four first rotating rods. The linkage gear assembly includes a second linkage gear meshing with the first linkage gear, a third linkage gear meshing with the second linkage gear, a second bevel gear fixed coaxially with the third linkage gear, and a first bevel gear meshing with the second bevel gear. The pivot of the support rod and the first rotating rod is hinged to the corresponding first bevel gear and is coaxial with it.

[0011] The lower surface of the rotating disk is fixedly connected to four cylindrical columns arranged in a circular array. The upper surface of the support frame is provided with a circular groove. The cylindrical columns are slidably connected to the circular groove. The four cylindrical columns are fixedly connected by a circular plate.

[0012] It also includes a second drive unit, which includes a U-shaped frame. The U-shaped frame includes a horizontal plate and vertical plates fixed to both ends of the horizontal plate. Two vertical plates are correspondingly provided with first cranks. One end of each first crank is rotatably connected to the corresponding vertical plate, and the other ends of the two first cranks are rotatably connected via a swing rod. A second crank is connected to the middle of one side wall of the horizontal plate. The input shaft of the second crank is rotatably engaged with the horizontal plate. A movable column is movably sleeved at the output end of the second crank. The movable column is slidably connected to the swing rod. One of the vertical plates is fixedly connected to the rotating disk, and the other... The vertical plate is fixedly connected to the annular plate. A gear one coaxial with the input shaft of the second crank is provided on one side of the horizontal plate. An incomplete gear meshes with one side of the gear one. A baffle is fixedly connected to the gear one coaxially. A limiting plate that mates with the incomplete gear on the baffle is provided. Arc-shaped grooves are provided on both sides of the baffle. The limiting plate is shaped like a chamfer. The side of the limiting plate is parallel to the notch surface of the limiting plate. The arc-shaped groove of the baffle matches the arc surface of the limiting plate. A second motor is provided on one side of the limiting plate. The output shaft of the second motor is fixedly coaxially with the incomplete gear.

[0013] The magnetic attraction unit includes an electromagnet disposed on two symmetrical sidewalls of the groove. A first push switch is disposed on the groove surface, and a second push switch is disposed on one side of the collection frame. The first push switch is used to control the electromagnet to be energized, and the second push switch is used to control the electromagnet to be de-energized.

[0014] A third push switch is provided on the upper surface of the fixed plate, which is used to control the operation of the first motor and the second motor.

[0015] S1: Step on the pedal once to make the pedal lever swing, which in turn drives the connecting rod to rotate the first pawl. When the first pawl rotates, it drives the lifting column to move upward. At the same time, when the lifting column moves upward, it drives the second pawl to rotate. When the lifting column has finished moving upward, the second pawl can prevent the lifting column from moving downward. At the same time, when the lifting column moves upward, it drives several linearly arranged picture frames to move upward, so that the picture frame at the top layer enters the groove of the collection frame and contacts the first push switch, which energizes the electromagnet. Each picture frame has a design drawing placed on it, and iron bars are set on both sides of the picture frame so that the electromagnet can attract the picture frame.

[0016] S2: When the pedal is stepped on once, the pedal lever swings, causing the pedal to contact the third push switch, which causes the output shaft of the first motor and the output shaft of the second motor to rotate one revolution. When the output shaft of the first motor rotates one revolution, it drives the dial to rotate one revolution, which in turn drives the groove wheel to rotate, causing the rotating disk to rotate 90°, so that the collection frame of the picture frame is rotated to the front.

[0017] The process involves flipping the frame. When the output shaft of the second motor rotates one revolution, the second crank rotates half a revolution, causing the moving column to slide on the second crank. This, in turn, causes the first crank to swing 90°, which in turn causes the third linkage gear, coaxial with the first crank, to rotate a quarter revolution. This third linkage gear, through the cooperation of the second and first linkage gears, drives the other three third linkage gears to rotate, which in turn causes the first rotating rod to rotate 90°, causing the connecting shaft to rotate a quarter revolution. This, in turn, causes the collecting frame to flip 90°, allowing it to adhere to the frame. The design diagram of the flipped collecting frame is easy to explain and observe.

[0018] S3: After explaining the design drawing on the collection frame of the picture frame, press the pedal again to engage the third push-button switch. This causes the output shafts of the first and second motors to rotate one revolution. When the first motor's output shaft rotates one revolution, it drives the dial to rotate one revolution, which in turn drives the grooved wheel to rotate, causing the rotating disk to rotate 90°. This moves the collection frame of the picture frame to one side of the rectangular collection box. Simultaneously, when the second motor's output shaft rotates one revolution, the second crank rotates half a revolution, causing the moving column to slide on the second crank, which in turn drives the first crank. The crank swings 90°, which in turn drives the third linkage gear, which is coaxial with the first crank, to rotate a quarter turn. When this third linkage gear rotates, it drives the other three third linkage gears to rotate through the cooperation of the second linkage gear and the first linkage gear. This drives the first rotating rod to rotate 90°, causing the connecting shaft to rotate a quarter turn. This causes the collecting frame to rotate 90°, so that the collecting frame that adsorbs the picture frame flips and fits into the rectangular collecting box 10. When the collecting frame that adsorbs the picture frame fits into the rectangular collecting box, the second pressing switch contacts the upper surface of the rectangular collecting box to control the electromagnet to de-energize, causing the picture frame to fall into the rectangular collecting box.

[0019] The beneficial effects of the technical solution provided by the embodiments of the present invention are as follows: the device is ingeniously designed and easy to operate. The step-lifting mechanism facilitates the adsorption of picture frames, while the grooved wheel mechanism enables the adsorbed picture frames to rotate to the front. The rotation of the second motor causes the collection frame of the adsorbed picture frames to flip over, making it easier to explain and observe. When the collection frame of the adsorbed yellow frame flips over and fits into the rectangular collection box, it is easy to collect the picture frames, thus improving the practicality of the device.

[0050] Rectangular storage box 1 and rectangular collection box 10

[0051] A first hinged door 100 is hinged to one side of a rectangular storage box 1, and a second hinged door 101 is hinged to one side of a rectangular collection box 10.

[0052] S1: Step on the pedal 331 once, causing the pedal lever 330 to swing, which in turn drives the connecting rod 34 to move, causing the first pawl 36 to rotate. When the pawl of the first pawl 36 rotates, it drives the lifting column 300 to move upward. At the same time, when the lifting column 300 moves upward, it drives the second pawl 37 to rotate. After the lifting column 300 has moved upward, the pawl of the second pawl 37 can prevent the lifting column 300 from moving downward. At the same time, when the lifting column 300 moves upward, it drives several linearly arranged picture frames to move upward, so that the picture frame at the top layer enters the groove of the collection frame 73 and contacts the first push switch 75, which energizes the electromagnet 74. The picture frames are all placed with design drawings, and iron bars are set on both sides of the picture frames, so that the electromagnet 74 attracts the picture frames.

[0053] S2: When the pedal 331 is stepped on once, the pedal lever 330 swings, causing the pedal 331 to contact the third push switch 92, causing the output shaft of the first motor 91 and the output shaft of the second motor 63 to rotate one revolution. When the output shaft of the first motor 91 rotates one revolution, it drives the dial 51 to rotate one revolution, which in turn drives the groove wheel 5 to rotate, causing the rotating disk 2 to rotate 90°, so that the collection frame 73 that adsorbs the picture frame rotates to the front.

[0054] The rotation proceeds; when the output shaft of the second motor 63 rotates one revolution, the second crank 83 rotates half a revolution, causing the moving column 86 to slide on the second crank 83, which in turn causes the first crank 81 to swing 90°, thereby causing the third linkage gear 79, which is coaxial with the first crank 81, to rotate a quarter revolution. When this third linkage gear 79 rotates, it drives the other three third linkage gears 79 to rotate through the cooperation of the second linkage gear 78 and the first linkage gear 77, which in turn causes the first rotating rod 71 to rotate 90°, causing the connecting shaft 730 to rotate a quarter revolution, thereby causing the collecting frame 73 to rotate 90°, so that it can be attracted to the frame. The design drawing of the collected frame 73 after the rotation is easy to explain and observe.

[0055] S3: After explaining the design drawing on the collection frame 73 of the picture frame, step on pedal 331 again to make it contact the third push switch 92. This causes the output shafts of the first motor 91 and the second motor 63 to rotate one revolution. When the output shaft of the first motor 91 rotates one revolution, it drives the dial 51 to rotate one revolution, which in turn drives the grooved wheel 5 to rotate, causing the rotating disk 2 to rotate 90°. This allows the collection frame 73 of the picture frame to rotate to one side of the rectangular collection box 10. Simultaneously, when the output shaft of the second motor 63 rotates one revolution, it causes the second crank 83 to rotate half a revolution, which in turn drives the moving column 86 to slide on the second crank 83, thereby driving the first crank 81... The swinging motion of the crank 79 causes the third linkage gear 79, which is coaxial with the first crank 81, to rotate a quarter turn. When the third linkage gear 79 rotates, it drives the other three third linkage gears 79 to rotate through the cooperation of the second linkage gear 78 and the first linkage gear 77. This, in turn, causes the first rotating rod 71 to rotate 90°, which in turn causes the connecting shaft 730 to rotate a quarter turn. This causes the collecting frame 73 to rotate 90°, so that the collecting frame 73 adsorbing the picture frame is in contact with the rectangular collecting box 10. When the collecting frame 73 adsorbing the picture frame is in contact with the rectangular collecting box 10, the second pressing switch 750 contacts the upper surface of the rectangular collecting box 10 to control the electromagnet 74 to be de-energized, so that the picture frame falls into the rectangular collecting box 10.

[0056] 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 principles of the present invention should be included within the protection scope of the present invention.

2. The presentation method of the interior design drawing display device according to claim 1, characterized in that, S1: Step on the pedal (331) once, causing the pedal rod (330) to swing, which in turn drives the connecting rod (34) to move, causing the first pawl (36) to rotate. When the pawl of the first pawl (36) rotates, it drives the lifting column (300) to move upward. At the same time, when the lifting column (300) moves upward, it drives the second pawl (37) to rotate. When the lifting column (300) has finished moving upward, the pawl of the second pawl (37) can prevent the lifting column (300) from moving downward. At the same time, when the lifting column (300) moves upward, it drives several linearly arranged picture frames to move upward, so that the picture frame at the top layer enters the groove of the collection frame (73) and contacts the first push switch (75), which makes the electromagnet (74) energized. The picture frames are all placed with design drawings, and iron bars are set on both sides of the picture frames, so that the electromagnet (74) attracts the picture frames. S2: When the pedal (331) is stepped on once, the pedal lever (330) swings, causing the pedal (331) to contact the third push switch (92), causing the output shaft of the first motor (91) and the output shaft of the second motor (63) to rotate one revolution. When the output shaft of the first motor (91) rotates one revolution, it drives the dial (51) to rotate one revolution, which in turn drives the groove wheel (5) to rotate, causing the rotating disk (2) to rotate 90°, so that the collection frame (73) of the picture frame is rotated to the front. The rotation is performed; when the output shaft of the second motor (63) rotates one revolution, the second crank (83) rotates half a revolution, causing the moving column (86) to slide on the second crank (83), thereby causing the first crank (81) to swing 90°, and then causing the third linkage gear (79) coaxial with the first crank (81) to rotate a quarter revolution. When this third linkage gear (79) rotates, it drives the other three third linkage gears (79) to rotate through the cooperation of the second linkage gear (78) and the first linkage gear (77), thereby causing the first rotating rod (71) to rotate 90°, causing the connecting shaft (730) to rotate a quarter revolution, and then causing the collection frame (73) to rotate 90°, so that it can be attracted to the collection frame (73) after the rotation. The design drawing of the collection frame (73) after the rotation is easy to explain and observe. S3: After explaining the design drawing on the collection frame (73) of the picture frame, step on the pedal (331) again to make the pedal (331) contact the third push switch (92), causing the output shaft of the first motor (91) and the output shaft of the second motor (63) to rotate one revolution. When the output shaft of the first motor (91) rotates one revolution, it drives the dial (51) to rotate one revolution, which in turn drives the groove wheel (5) to rotate, causing the rotating disk (2) to rotate 90°, so that the collection frame (73) of the picture frame rotates to one side of the rectangular collection box (10). At the same time, when the output shaft of the second motor (63) rotates one revolution, it causes the second crank (83) to rotate half a revolution, which drives the moving column (86) to slide on the second crank (83), which in turn drives the first crank (81) to rotate. The first crank (81) swings 90°, which in turn drives the third linkage gear (79) coaxial with it to rotate a quarter turn. When the third linkage gear (79) rotates, it drives the other three third linkage gears (79) to rotate through the cooperation of the second linkage gear (78) and the first linkage gear (77), which in turn drives the first rotating rod (71) to rotate 90°, so that the connecting shaft (730) rotates a quarter turn, which in turn drives the collection frame (73) to flip 90°, so that the collection frame (73) adsorbing the picture frame flips and fits into the rectangular collection box 10. When the collection frame (73) adsorbing the picture frame fits into the rectangular collection box (10), the second press switch (750) contacts the upper surface of the rectangular collection box (10) to control the electromagnet (74) to be de-energized, so that the picture frame falls into the rectangular collection box (10).
