Description

Technical Field

[0001] This invention relates to the field of teaching drawing boards, specifically a drawing board for art teaching for hearing-impaired students. Background Technology

[0002] In painting, drawing paper or canvas is usually laid on a drawing board. The basic function of the drawing board is to support the drawing paper or canvas. When the drawing paper is fixed to the drawing board, the completion of a painting often takes several hours to several days. Therefore, it is generally necessary to fix the drawing paper to the drawing board stably for a long time. This is usually done with tape. However, when the drawing paper is removed with tape, the tape needs to be peeled off. If the tape is peeled off accidentally, it is easy to damage the paper. In addition, in special education, it is not easy to remind hearing-impaired students to "listen" through sound signals when teaching art. To address these issues, a drawing board for art teaching for hearing-impaired students is proposed. Summary of the Invention

[0003] The purpose of this invention is to provide a drawing board for art teaching for hearing-impaired students, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A drawing board for art teaching for hearing-impaired students, including Page 1 has a rotatable connection to page 2 at one end. Both page 1 and page 2 have internal cavities on their adjacent surfaces. The adjacent surfaces of page 1 and page 2 are the back surfaces. Page 1 has two support rods, which are used to support the opening angle of page 2. A top clamp assembly is installed at the top of the back of the second page plate. When unfolded, the top clamp assembly is used to clamp and fix the paper to the top of the front of the second page plate. When retracted, the top clamp assembly is placed between the two first and second page plates. The top clamp assembly includes two fixed rails, which are respectively fixedly installed on both sides of the top of the back of the second page plate. An extension frame is slidably connected to the fixed rails. One end of the extension frame is rotatably connected to a second connecting rod frame. One end of the second connecting rod frame is rotatably connected to a deflection frame. The other end of the second connecting rod frame is rotatably connected to a first connecting rod frame. One end of the first connecting rod frame is slidably connected to the extension frame. A clamping frame is slidably connected between the two deflection frames. A binding assembly is slidably mounted on the back of the second sheet, the binding assembly including an elastic cord for securing the bottom of the paper to the front of the second sheet.

[0005] Furthermore, a vibration unit is embedded in the first page plate, and the vibration unit can be started and stopped remotely.

[0006] Furthermore, the fixed rail frame has a limiting rail groove, the other end of the extension frame has a short groove, and an outer protrusion is fixedly installed on the outer side wall of one end of the extension frame at both ends of the short groove. The outer protrusion is slidably connected to the limiting rail groove. One end of the first connecting rod frame is rotatably connected to a round rod, which is slidably connected to the short groove. A limiting rod is fixedly connected between the two round rods. A torsion spring is fixedly installed between one end of the deflection frame and one end of the second connecting rod frame. The torsion spring is used to drive the deflection frame to deflect in the direction of conforming to the second connecting rod frame.

[0007] Furthermore, the clamping frame has two clearance grooves at both ends corresponding to the extension frame. The clearance grooves are used to allow the extension frame to pass, so that the clamping frame and the connecting rod frame can fit together.

[0008] Furthermore, a spring block is installed on the back of the second page plate, a frame is installed in the middle of the limiting rod, the frame is used to engage with the spring block, and an avoidance groove is provided at the top of the second page plate, the thickness of the clamping frame is the same as the thickness of the avoidance groove.

[0009] Furthermore, the clamping frame has a third clearance groove at its middle position, which is used to avoid the spring block.

[0010] Furthermore, side guide rails are fixedly installed on both sides of the back of the second page plate, and a sliding seat is slidably connected to the side guide rail. A connecting seat is rotatably connected to one end of the sliding seat, and one end of the connecting seat is rotatably connected to the end of the elastic rope. The deflection angle range of the connecting seat on the sliding seat is 180 degrees.

[0011] Furthermore, both sides of the back of the first and second page plates are provided with storage slots, and the inner bottom surface of the storage slots is provided with multiple stop slots. The stop slots are used to engage the end of the support rod, and the storage slots are used to store the support rod.

[0012] Furthermore, a bushing tube is fixedly installed at one end of the first page plate, and bushing tubes are fixedly installed on both sides of one end of the second page plate. The first bushing tube is rotatably connected between the two bushing tubes. Threaded holes are opened at both ends of the first bushing tube. A fastening knob is rotatably installed on the second bushing tube, and one end of the fastening knob is screwed into the first bushing tube.

[0013] Furthermore, a cloth bag is installed on the back of the second page plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: With the top clamp assembly and restraint assembly in place, the top clamp assembly can be manually operated to unfold, allowing the extension frame to push upwards along the fixed rail. A triangular frame is formed between the second linkage frame, the first linkage frame, and the extension frame. The top of the second linkage frame deflects above the second page plate. Then, the clamping frame is manually driven to deflect and extend, squeezing and clamping the top of the paper onto the front of the second page plate. This facilitates the installation and fixing of papers of different sizes, avoids damage to the paper, and is easy to use. The internal cavities on the first and second page plates allow the top clamp assembly to be retracted between the two page plates during storage, resulting in a neat appearance when the two page plates are closed. This makes it easy to carry and store, and the retraction facilitates the storage of drawing paper, making it convenient for use when traveling. Furthermore, the vibration of the page plate that is stuck in the paper can be remotely controlled by a vibration power source to send a signal to remind the students, facilitating the teaching process. With the binding component in place, the top clamping component holds and fixes the top of the paper. Then, manually pulling the elastic rope moves it from the top of the second sheet plate to the front of the second sheet plate. The elastic rope then restrains the bottom of the paper, pressing it against the front of the second sheet plate to prevent it from floating. Since the position of the elastic rope can be adjusted along the side guide rail, it is convenient to install different sizes of paper on the second sheet plate for easy use.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1 to 7In this embodiment of the invention, a drawing board for art teaching for hearing-impaired students includes a first page 100, a top clamp assembly 300, and a restraint assembly 400. One end of the first page 100 is rotatably connected to a second page 200. Both the first and second page 100 have adjacent cavities on their adjacent surfaces, which are their back surfaces. Two support rods 140 are provided on the first page 100 to support the opening angle of the second page 200. The top clamp assembly 300 is installed at the top of the back surface of the second page 200. When unfolded, the top clamp assembly 300 clamps and fixes the paper to the top of the front surface of the second page 200. When retracted, the top clamp assembly 300 is placed between the two pages 100 and 200. The top clamp assembly 300 includes two fixed rails 310 and two fixed... The fixed rail frame 310 is fixedly installed on both sides of the top back of the second page plate 200. An extension frame 320 is slidably connected to the fixed rail frame 310. One end of the extension frame 320 is rotatably connected to the second linkage frame 340. One end of the second linkage frame 340 is rotatably connected to the deflection frame 350. The other end of the second linkage frame 340 is rotatably connected to the first linkage frame 330. One end of the first linkage frame 330 is slidably connected to the extension frame 320. A clamping frame 360 ​​is slidably connected between the two deflection frames 350. A restraint assembly 400 is slidably installed on the back of the second page plate 200. The restraint assembly 400 includes an elastic rope 430, which is used to restrain the bottom of the paper to the front of the second page plate 200. A vibration unit 130 is embedded in the first page plate 100. The vibration unit 130 can be started and stopped by remote control.

[0019] Specifically, when carried, page 100 and page 200 are in a closed state. When in use, page 100 and page 200 are opened at an angle, with page 100 as the base, and the paper is placed on the front of page 200. After page 200 is opened, the support rod 140 is placed between page 100 and page 200 to support page 200. Then, the top clamp assembly 300 is manually operated to unfold, so that the extension frame 320 is pushed upward along the fixed rail frame 310. A triangular frame is formed between the second linkage frame 340, the first linkage frame 330, and the extension frame 320. The top of the second linkage frame 340 is deflected above page 200. Then, the clamping frame 360 ​​is manually driven to deflect and extend. The paper is clamped at the top of the sheet 200 by pressing it against the front. Then, the elastic cord 430 is manually pulled, moving it from the top of the sheet 200 to the front. The elastic cord 430 restrains the bottom of the paper, pressing it against the front of the sheet 200 to prevent it from floating. This allows for easy mounting of different sized sheets on the sheet 200. The internal cavities on the sheet 100 and sheet 200 facilitate the storage of drawing paper. The vibration unit 130 allows hearing-impaired students to use the sheet, and the teacher can remotely control the vibration to start and stop it, reminding students to "listen," thus facilitating teaching. Example 1

[0020] like Figures 4-9 As shown, in this embodiment, a limiting groove 311 is provided on the fixed rail frame 310, and a short groove 321 is provided at the other end of the extension frame 320. External protrusions 322 are fixedly installed on the outer side wall of one end of the extension frame 320 at both ends of the short groove 321. The external protrusions 322 are slidably connected to the limiting groove 311. A round rod 331 is rotatably connected to one end of the first connecting rod frame 330, and the round rod 331 is slidably connected to the short groove 321. A limiting rod 370 is fixedly connected between the two round rods 331. A torsion spring is fixedly installed between the deflection frame 350 and one end of the second connecting rod frame 340. The torsion spring is used to drive the deflection frame 350 towards the connecting rod frame 340. With the direction deflected, the two ends of the clamping frame 360 ​​are provided with clearance grooves 361 corresponding to the positions of the extension frame 320. The clearance grooves 361 are used to avoid the extension frame 320, so that the clamping frame 360 ​​and the connecting rod frame 340 fit together. The back of the page plate 200 is equipped with a spring block 240. The middle position of the limiting rod 370 is equipped with a frame 371, which is used to engage with the spring block 240. The top of the page plate 200 is provided with a clearance groove 230. The thickness of the clamping frame 360 ​​is the same as the thickness of the clearance groove 230. The middle position of the clamping frame 360 ​​is provided with a clearance groove 362, which is used to avoid the spring block 240.

[0021] In this embodiment, after the second page 200 is unfolded, the limiting rod 370 is manually pushed upward until the frame 371 engages with the spring block 240. The engagement of the spring block 240 with the frame 371 limits the limiting rod 370. When the limiting rod 370 moves upward, the extension frame 320 is moved upward through the first linkage frame 330 until the outer protrusion 322 abuts against the top of the limiting rail groove 311. Subsequently, the continued upward movement of the limiting rod 370 causes the bottom end of the first linkage frame 330 to move upward along the short groove 321, so that the second linkage frame 340... The top of the lever deflects towards the front side of the second page plate 200 (when the first link frame 330 and the second link frame 340 are in contact, the second link frame 340 can be manually deflected in advance). After the limit rod 370 and the spring block 240 are engaged, the position and deflection angle of the second link frame 340 are fixed. Then the deflection frame 350 is deflected outward, so that the deflection frame 350 overcomes the torsion force of the torsion spring and deflects outward, and the clamping frame 360 ​​is pulled outward. Then the deflection frame 350 and the clamping frame 360 ​​are released. The clamping frame 360 ​​is in the torsion spring. Under the action of the spring, the clamping frame 360 ​​deflects back, thereby clamping and fixing the paper to the second page plate 200. When storing, the clamping frame 360 ​​is retracted upward relative to the deflection frame 350 to avoid interference between the clamping frame 360 ​​and the second page plate 200. The second linkage frame 340 deflects to fit against the second linkage frame 340 under the action of the torsion spring. Press the spring block 240 to disengage it from the frame 371. Pull the limiting rod 370 down to the bottom, causing the extension frame 320 to move down. The short groove 321 at the bottom of the extension frame 320 and the limiting rod 371 are engaged. After the bottom end of the guide groove 311 abuts, the limiting rod 370 continues to move downward, pulling the bottom end of the first linkage frame 330 downward, so that the first linkage frame 330 and the second linkage frame 340 are straightened. The deflection frame 350 and the limiting rod 370 retract into the inner cavity of the second page plate 200. When the first page plate 100 and the second page plate 200 are closed, the first page plate 100 blocks the second linkage frame 340 and limits the top clamp assembly 300, so as to realize the unfolding and storage of the top clamp assembly 300, which facilitates the stable fixation of the paper.

[0022] like Figure 3 As shown, in this embodiment, a cloth bag 120 is installed on the back of the second page 200.

[0023] In practice, the paper can be stored in the inner cavity of the first page plate 100. The cloth bag 120 reduces the paper from being blown away and scattered when placed in the inner cavity of the first page plate 100. At the same time, when the first page plate 100 and the second page plate 200 are closed, the cloth bag 120 is located between the top clamping assembly 300 and the stored paper, thereby preventing the components on the top clamping assembly 300 from contacting the paper and achieving protection for the paper. Example 2

[0024] like Figures 1-10As shown, in this embodiment, side guide rails 250 are fixedly installed on both sides of the back of the second page plate 200. A sliding seat 410 is slidably connected to the side guide rail 250. A connecting seat 420 is rotatably connected to one end of the sliding seat 410. One end of the connecting seat 420 is rotatably connected to the end of the elastic rope 430. The deflection angle range of the connecting seat 420 on the sliding seat 410 is 180 degrees. A storage groove 110 is provided on both sides of the back of the first page plate 100 and the second page plate 200. A plurality of stop slots are provided on the inner bottom surface of the storage groove 110. 111, the gear slot 111 is used to snap the end of the support rod 140, the storage slot 110 is used to store the support rod 140, one end of the first page plate 100 is fixedly installed with the first bushing 150, and both sides of one end of the second page plate 200 are fixedly installed with the second bushing 210. The first bushing 150 is rotatably connected between the two second bushings 210. Both ends of the first bushing 150 are provided with threaded holes. The second bushing 210 is rotatably installed with the fastening knob 220, and one end of the fastening knob 220 is screwed into the first bushing 150.

[0025] In practical implementation, through the setting of elastic cord 430 and connecting seat 420, when stored, elastic cord 430 is located on the back of page plate 200, and the two connecting seats 420 are in opposite positions. When using elastic cord 430, pull elastic cord 430 to pass over the top of page plate 200, thereby moving elastic cord 430 to the front of page plate 200. Then, according to the position of the bottom of the paper, slide sliding seat 410 to press and constrain the bottom of the paper with elastic cord 430. Through the rotational connection between elastic cord 430 and connecting seat 420, when the front of page plate 200 of elastic cord 430 moves from top to bottom, elastic cord 430 rolls on the paper, thereby flattening the paper and reducing friction on the paper when elastic cord 430 moves, making it convenient to use.
