The pulley can be riveted in one piece, which has a stable structure and high assembly efficiency.

[0062] Embodiment 2

[0063] The difference between the sliding assembly of this embodiment and the first embodiment is that the arrangement orientation of the sliding wheel 12 is different.

[0064] Specific as Fig. 9 , Fig.10 As shown, the sliding assembly includes a transverse moving assembly 1 capable of transversely moving along the slide rail 3, and the transverse moving assembly 1 has a transverse moving frame 11, a sliding wheel 12 and a support member 14; the sliding wheel 12 is a transverse wheel arranged on the first side (i.e. Fig. 9 The support slider is arranged on the left or right side of the traverse frame 11, and the support slider is arranged on the second side of the traverse frame 11 (i.e. Fig. 9 The upper side of the slide rail 3, wherein the first side and the second side of the transverse frame 11 are two sides that are perpendicular to each other, the sliding wheel 12 abuts against the first side of the slide rail 3, and the supporting slider abuts against the second side of the slide rail 3, wherein the first side and the second side of the slide rail 3 are two sides that are perpendicular to each other.

[0065] In this embodiment, the lateral sliding wheel 12 is pressed against the front and rear sides (i.e. Fig. 9The left and right sides of the slide rail 3 are then supported by the support member 14 on the upper side of the slide rail 3 (in the upper sliding assembly, the sliding wheel 12 is supported on the lower side of the slide rail 3), so that the transverse movement assembly 1 is in close contact with the slide rail 3, avoiding the sliding assembly from jumping during the sliding process, increasing the stability during sliding, and improving the user experience.

[0066] In this embodiment, the support member 14 may be as follows Fig. 9 The support wheel shown can also be Fig.10 The support slider shown can achieve the support function so that the lateral movement component 1 is in close contact with the slide rail 3 to prevent jumping. Among them, the support slider can adopt the existing structure, and it should be noted that when using the support slider, the interference should be reasonably controlled to control the damping force when the lateral movement component 1 moves when preventing jumping. The other structures such as the track change component 2 of this embodiment are the same as those of the first embodiment.

[0067] Embodiment 3

[0068] Based on the sliding assembly of embodiment 1 or embodiment 2, this embodiment also provides a planar track change blackboard, such as Fig.11 As shown, it includes a fixed plate 5, a movable plate 4, a slide rail 3 and a sliding assembly, as shown in Fig.12 , Fig.13 As shown, the track changing track of the slide rail 3 is a single track changing guide groove 32. This single track changing guide groove 32 is relative to the prior art. An existing track changing sliding blackboard is provided with two parallel guide wheel grooves, and the end of each guide rail groove is provided with a right-angle track changing guide wheel groove with a circular arc transition. In this embodiment, each slide rail 3 has only one guide groove for track changing.

[0069] A first track-changing block 321 (such as Fig.14 as shown) and the second track change block 322 (as shown Fig.15 As shown), along the length direction of the track change guide groove 32, the first track change block 321 is located on the inner side of the second track change block 322, that is, Fig.12 In the figure, the left side is the inner side of the slide rail 3, and the right side is the outer side of the slide rail 3. The first track-changing block 321 is located on the left side, and the second track-changing block 322 is located on the right side. The first track-changing block 321 has a first track-changing channel communicating with the track-changing guide groove 32, and the first track-changing channel and the track-changing guide groove 32 have a set angle. The second track-changing block 322 has a second track-changing channel communicating with the track-changing guide groove 32, and the second track-changing channel is perpendicular to the track-changing guide groove 32. Furthermore, a baffle is provided on the second track-changing channel, that is, the inner side of the second track-changing block 322 has a raised structure, and the positioning wheel of the inner sliding assembly of the movable plate and the positioning wheel of the outer sliding assembly slide on different horizontal planes. With the setting of the baffle, the inner positioning wheel will not change track at the position of the second track-changing block, but can only move to the position of the first track-changing block to change track.

[0070] When in use, first move the movable board 4 horizontally, and when the track-changing assembly 2 inside the movable board 4 moves to the position of the first track-changing block 321, first tilt it toward the inside of the blackboard and slowly change the track, and when the track-changing assembly 2 outside the movable board 4 moves to the second track-changing block 322, push the movable board 4 inward to complete the track-changing process of the movable board 4. Through the single track-changing guide groove 32, the thickness of the entire slide rail 3 is reduced, the structural volume is reduced, and the track-changing process is smoother through the cooperation of the inclined first track-changing block 321 and the vertical second track-changing block 322.

[0071] The slide rails 3 are provided with two, and the two slide rails 3 are arranged in parallel on the upper and lower sides. The fixed plate 5 is installed in front of the two slide rails 3, with an LCD screen in the middle. The movable plate 4 is located in front of the fixed plate 5 and the LCD screen, and the upper and lower sides of the movable plate 4 are each installed on the two slide rails 3 through two sets of sliding components.

[0072] When the LCD screen is not in use, the movable panel 4 can be moved to the rear side to be flush with the fixed panel 5 during the closing process, forming a purely flat appearance structure. The slide rail 3 is arranged on the rear side of the fixed panel 5 and the movable panel 4, that is, a hidden slide rail 3 is adopted. After closing, there is no leakage of the outer frame of the slide rail 3 (only part of the slide rail 3 leaks when opened), and the shape is simple and beautiful. The gap between the movable panel 4 and the fixed panel 5 is ≤8mm, which meets the safety and sanitation requirements of GB 28231 writing board (≤8mm or ≥25mm), and reduces the visual obstruction to students on the side while avoiding pinching hands.

[0073] The slide rail 3 can adopt a two-way L-shaped wall mounting part, and the two sides can be used flexibly to adapt to the distance of various large screens from the wall. After installation, the left and right positions of the movable plate 4 and the fixed plate 5 can be adjusted to adjust the gap between the plates after closing. The fixed plate 5 or the movable plate 4 can be directly removed from the front for easy maintenance.

[0074] like Fig.16 As shown, the movable panel 4 and the fixed panel 5 both have a panel body 41, and the edge of the panel body 41 is provided with a self-wrapped edge 42, that is, the panel is wrapped around the side from the front of the panel body 41 to the back, and the panel 2 can be fixed by bonding, riveting or other connection methods, which are not specifically limited in this embodiment. Further, the angle between the side and the front of the panel is less than 90°, that is, Fig.16 The angle between the middle left side and the lower side is less than 90°, and the edges of the movable plate 4 and the fixed plate 5 adopt the self-wrapping 42 process, which saves the frame structure, so that the movable plate 4 and the fixed plate 5 after closing form a pure flat appearance structure, and there is no obvious separation between the various plates, so the overall sense is stronger, and the whole plate can be written continuously.

[0075] like Fig.17As shown, a rack 6 is provided in the middle of the lower slide rail 3, and the rack 6 includes a baffle 61 and a connecting plate 62. Fig.18 As shown, the connecting plates 62 are located at both ends of the baffle plate 61 and can be connected to the connecting plates 62 by screws. The connecting plates 62 can be detachably mounted on the slide rail 3. By arranging the storage rack 6 on the slide rail 3, a storage space is formed to place erasers, teaching aids, etc., which increases the storage function. Moreover, when the movable plate 4 is closed, it can be shielded, and the overall appearance is more beautiful. Fig.19 As shown, a support plate 7 may also be provided on the bottom side of the lower slide rail 3, as shown in FIG. Fig. 20 As shown, the support plate 7 includes a vertical plate and a horizontal plate, and the vertical plate and the horizontal plate form an L shape. The horizontal plate is tilted upward on the side away from the vertical plate (i.e., the front side of the blackboard), which meets the requirements of the new "Chalk Writing Board" industry standard. It can also be used to place erasers, chalks and other items without being constrained by the desk. At the same time, the front end of the support plate 7 is tilted to prevent round chalks and other items from sliding off, making it easy to use.

[0076] It can be understood that the planar track-changing blackboard can also be provided with a driving mechanism, which includes: a controller, a driver, a synchronous motor and a travel switch; the controller controls whether to provide power to the driver according to the received instructions, the driver is connected to the synchronous motor, the synchronous motor drives the sliding wheel to rotate, and the travel switch is arranged at both ends of the maximum sliding range of the slide rail. The synchronous motor drives the sliding wheel 12 and the track-changing wheel 21 to rotate, thereby realizing automatic transverse movement and automatic track changing. The above-mentioned electric control is easily implemented by technicians in this field based on the prior art.

[0077] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
