Technical Field

[0001] This utility model relates to the field of teaching equipment technology, and in particular to an interactive teaching whiteboard. Background Technology

[0002] A whiteboard is an interactive tool used in classroom teaching or training to replace or supplement traditional blackboards. It is generally divided into two types: physical whiteboards and electronic whiteboards. Physical whiteboards have a smooth white panel, are written on with whiteboard markers, can be erased and reused, and avoid chalk dust pollution. They are commonly found in classrooms and conference rooms.

[0003] In existing technologies, when teaching whiteboards are used, if the whiteboard is small, the teaching content is often not finished before the whiteboard area is insufficient. If the whiteboard is large, it tends to occupy a lot of space, and it is not convenient to move or use, resulting in poor teaching interaction between teachers and students. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing technology of teaching whiteboards. When the teaching whiteboard is small, the teaching content is often not finished before the whiteboard area is insufficient. When the teaching whiteboard is large, it tends to occupy a lot of space and is not convenient to move, which leads to poor teaching interaction between teachers and students.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an interactive teaching whiteboard, comprising: a frame, and further comprising:

[0006] Two sliding grooves are respectively opened on opposite sides of the frame. A main whiteboard is fixedly connected to one side of the inner wall of the two sliding grooves, and a secondary whiteboard is slidably connected to the inner wall of the sliding groove. A U-shaped plate is fixedly connected to the back side of the frame. A movable strip is rotatably connected to the center of the U-shaped plate through a support rod. Both ends of the movable strip are rotatably connected to the second movable strip through support rods. The second movable strip is rotatably connected to the secondary whiteboard through support rods.

[0007] Preferably, two sliding grooves are symmetrically formed on one side of the U-shaped plate, and a limiting block is fixedly connected to the back side of the sub-white board. The outer surface of the limiting block is slidably connected to the inside of the sliding groove.

[0008] Preferably, a magnet block two is fixedly connected to one side of the inner wall of the second slide, and the second limiting block is made of metal.

[0009] Preferably, the opposite side of the secondary whiteboard away from the limiting block two is fixedly connected to the limiting block one, the limiting block one is made of metal, and two magnet blocks one are symmetrically fixedly connected to the opposite side of the frame, and a handle is fixedly connected to one side of the secondary whiteboard.

[0010] Preferably, a base is provided below the frame, and two sleeves are symmetrically fixedly connected to the top of the base. A sliding rod is slidably connected inside the sleeve, and the sliding rod is fixedly connected to the frame. Universal self-locking wheels are fixedly connected to the four corners of the bottom of the base.

[0011] Preferably, the two slide rods are fixedly connected to the outer surface of the frame with connecting strip two, and the two sleeves are fixedly connected to the outer surface of the base with connecting strip one. A lead screw is threadedly connected to the center of the connecting strip one, one end of the lead screw is rotatably connected to the center of the connecting strip two, and the other end of the lead screw is fixedly connected to a throttle handle.

[0012] Preferably, multiple pen holders are fixedly connected to the front side of the frame.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. This utility model allows users to grasp the handle and pull it outwards, causing the connected secondary whiteboard to slide outwards along the inside of the first sliding groove. Simultaneously, a force is applied to one of the movable strips, causing it to rotate the first movable strip. This rotation of the first movable strip applies a force to the other movable strip, causing it to rotate at an appropriate angle and apply a pushing force to the other secondary whiteboard, moving it outwards along the inside of the first sliding groove. Both secondary whiteboards unfold outwards simultaneously, while a limiting block slides to one side along the inside of the second sliding groove. A magnet then attracts and holds the limiting block, keeping it in a fixed position. By adding extendable or retractable secondary whiteboards, the overall area of ​​the whiteboard is increased without increasing its overall size, making it easier for teachers to use and improving the effectiveness of teacher-student interaction.

[0015] 2. This utility model allows the screw to rotate by manually turning the handle. With the screw and connecting strip 1 connected by a thread, and the connecting strip 2 connected to the screw, the screw rotates upwards, applying an upward thrust to the connecting strip 1. This simultaneously drives the sliding rod to slide upwards along the inside of the sleeve, and simultaneously moves the frame, main whiteboard, and secondary whiteboard upwards. This allows the frame and secondary whiteboard to be adjusted to a suitable height, making it convenient for teachers of different heights to use. Attached Figure Description

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Examples, such as Figure 1-4 As shown, this utility model provides an interactive teaching whiteboard, including: a frame 104, and two sliding grooves 110 respectively opened on opposite sides of the frame 104. A main whiteboard 105 is fixedly connected to one side of the inner wall of the two sliding grooves 110, and a secondary whiteboard 2 is slidably connected to the inner wall of the sliding grooves 110. A U-shaped plate 205 is fixedly connected to the back side of the frame 104. A movable strip 207 is rotatably connected to the center of the U-shaped plate 205 through a support rod. Both ends of the movable strip 207 are rotatably connected to the movable strip 208 through support rods. The movable strip 208 and the secondary whiteboard 2 are rotatably connected through support rods.

[0025] Furthermore, such as Figure 1-4 As shown, two sliding grooves 206 are symmetrically opened on one side of the U-shaped plate 205. A limiting block 204 is fixedly connected to the back side of the sub-white plate 2. The outer surface of the limiting block 204 is slidably connected to the inside of the sliding groove 206. Through the above arrangement, it plays a certain supporting and guiding role for the sub-white plate 2.

[0026] Furthermore, such as Figure 1-4 As shown, a magnet block 209 is fixedly connected to one side of the inner wall of the slide 206. The limiting block 204 is made of metal. With the above settings, when the limiting block 204 comes into contact with the magnet block 209, the magnet block 209 can attract the limiting block 204.

[0027] Furthermore, such as Figure 1-4 As shown, the opposite side of the secondary whiteboard 2 away from the limiting block 204 is fixedly connected to the limiting block 202. The limiting block 202 is made of metal. The opposite side of the frame 104 is symmetrically fixedly connected to two magnet blocks 203. A handle 201 is fixedly connected to one side of the secondary whiteboard 2. With the above settings, when the limiting block 202 and the magnet block 203 come into contact, the magnet block 203 can attract the limiting block 202, thereby keeping the secondary whiteboard 2 in a certain fixed state. The handle 201 makes it easy to pull the secondary whiteboard 2.

[0028] Furthermore, such as Figure 1-4 As shown, a base 1 is provided below the frame 104. Two sleeves 102 are symmetrically fixedly connected to the top of the base 1. A sliding rod 103 is slidably connected inside the sleeve 102. The sliding rod 103 is fixedly connected to the frame 104. Universal self-locking wheels 101 are fixedly connected to the four corners of the bottom of the base 1. With the above settings, when the sliding rod 103 slides up and down along the inside of the sleeve 102, the height of the frame 104, the main whiteboard 105, and the secondary whiteboard 2 can be appropriately adjusted.

[0029] Furthermore, such as Figure 1-4 As shown, two sliding rods 103 are fixedly connected to connecting strip 2 107 near the outer surface of frame 104, and two sleeves 102 are fixedly connected to connecting strip 106 away from the outer surface of base 1. A lead screw 108 is threadedly connected to the center of connecting strip 106. One end of lead screw 108 is rotatably connected to the center of connecting strip 2 107, and the other end of lead screw 108 is fixedly connected to a handle 109. By turning the handle 109 by hand, the lead screw 108 is rotated. Then, with the threaded connection between lead screw 108 and connecting strip 106, and with the rotatable connection between connecting strip 2 107 and lead screw 108, lead screw 108 can be rotated upward, applying an upward thrust to connecting strip 106.

[0030] Furthermore, such as Figure 1-4 As shown, multiple pen holders 3 are fixedly connected to the front side of the frame 104, which facilitates the placement of whiteboard markers.

[0031] Working Principle: In use, by gripping handle 201 and pulling it outwards, the connected secondary whiteboard 2 slides outwards along the inside of slide groove 110. Simultaneously, a force is applied to one of the movable strips 208, causing it to rotate movable strip 207. This rotation of movable strip 207 then applies a force to the other movable strip 208, causing it to rotate at an appropriate angle. This also applies a pushing force to the other secondary whiteboard 2, causing it to move outwards along slide groove 110. Both secondary whiteboards 2 unfold outwards simultaneously. Simultaneously, the limiting block 204 slides to one side along slide groove 206, and the magnet 209 attracts and holds the limiting block 204, keeping it in a fixed position. By adding extendable or retractable secondary whiteboards 2, the overall surface area of ​​the whiteboard is increased without increasing its overall size. The design facilitates teacher use and enhances the teaching interaction between teachers and students. Conversely, when the secondary whiteboard 2 slides along the slide groove 110 into the frame 104, the limiting block 202 can contact the magnet block 203, causing the magnet block 203 to attract the limiting block 202, thus securing the secondary whiteboard 2. By manually turning the handle 109, the screw 108 is rotated. Then, with the screw 108 and connecting strip 106 threaded together, and with the connecting strip 107 rotating with the screw 108, the screw 108 can rotate upward, applying an upward thrust to the connecting strip 106. This simultaneously drives the slide rod 103 to slide upward along the inside of the sleeve 102, and simultaneously drives the frame 104, the main whiteboard 105, and the secondary whiteboard 2 to move upward. This allows the frame 104 and the secondary whiteboard 2 to be adjusted to a suitable height, making it convenient for teachers of different heights to use.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
