Description

Technical Field

[0001] This utility model relates to a blackboard, and more particularly to a sliding, coplanar blackboard. Background Technology

[0002] Nowadays, most multimedia classrooms use dust-free blackboards. Dust-free blackboards have replaced traditional blackboards and greenboards, eliminating the need for chalk and using easily erasable, dust-free, water-soluble pens, making them more efficient and environmentally friendly. Furthermore, in addition to blackboards, multimedia classrooms also require computers and projectors, with the projectors needing to be used in conjunction with a screen.

[0003] Currently, all movable multimedia classroom blackboards on the market slide on separate tracks, meaning the sliding blackboard is not on the same plane as the fixed or other blackboards. Therefore, when multiple blackboards slide together, they create a front-to-back positional relationship, making seamless connection impossible. This leads to dust accumulation at the joints, making cleaning difficult and affecting the blackboard's lifespan. Fixed blackboards, on the other hand, cannot flexibly adjust the writing area, limiting usable space and making them unsuitable for efficient teaching or office needs. Therefore, there is an urgent need for a seamless, aesthetically pleasing, durable, and flexibly sliding guide rail blackboard. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model discloses a sliding, coplanar connecting blackboard. After the sliding plate slides into place, it can form a seamless, coplanar connection with the fixed plate, solving the problems of dust accumulation and cleaning difficulties at the joint. This seamless connection primarily refers to existing technologies that do not involve coplanar connections.

[0005] The technical solution of this utility model is as follows:

[0006] A sliding coplanar blackboard includes a frame, a fixed plate, and a sliding plate. The frame includes an upper guide plate and a lower guide plate. The upper and lower ends of the fixed plate are fixedly connected to the upper guide plate and the lower guide plate, respectively. The upper guide plate and the lower guide plate are respectively provided with parallel upper guide grooves and lower guide grooves of the same shape.

[0007] A guide shaft that mates with the upper guide rail groove is provided on the upper back of the sliding plate, and a locking mechanism is provided on the back of the sliding plate; the locking mechanism includes a gear, a vertically arranged rack, an upper connecting rod, a lower connecting rod, and a switch shaft. The gear is located on one side of the rack and meshes with the rack. One end of the upper connecting rod and one end of the lower connecting rod are respectively connected to the gear at opposite positions. The other end of the upper connecting rod extends upward and connects to the upper baffle, and the other end of the lower connecting rod extends downward and connects to the lower baffle. One end of the switch shaft is fixedly connected to one end of the rack, and the switch shaft is slidably connected to the lower guide rail groove; the upper baffle, The lower baffle is located behind the sliding plate. The upper and lower guide rails are respectively provided with upper and lower locking mechanisms that engage with the upper and lower baffles. The upper and lower guide rail grooves are inclined forward at the middle position of the upper and lower guide rails. When the sliding plate reaches the position where it aligns with the fixed plate, the switch shaft is pulled to move the rack, which in turn moves the upper and lower connecting rods via gears, thereby causing the upper and lower baffles to move upward and downward respectively. When the upper and lower baffles are engaged with the upper and lower locking mechanisms respectively, the sliding plate and the fixed plate are on the same plane and their sides are adjacent. The sliding plate and the fixed plate are rectangular.

[0008] This technical solution involves moving the sliding plate, with the guide shaft and switch shaft connected to it sliding in the upper and lower guide grooves until the middle. The upper and lower guide grooves then tilt forward, bringing the sliding plate closer to the fixed plate. When the sliding plate is in the closed position, pulling the switch shaft moves the rack downwards, causing the gear to rotate clockwise. This, in turn, moves the upper and lower baffles upwards and downwards via the upper and lower connecting rods, engaging with the upper and lower locking mechanisms. This achieves the close proximity and locking of the sliding plate and the fixed plate, resulting in a seamless, planar connection. This solves the problem of dust accumulation and cleaning difficulties at the joint, and the switch shaft allows for easy hand operation, improving usability. The unlocking action of the sliding plate is the reverse of the above.

[0009] As a further improvement of this utility model, the upper locking mechanism and the lower locking mechanism are respectively upper baffle grooves and lower baffle grooves that match the dimensions of the upper baffle and the lower baffle. This technical solution has a simple structure and provides reliable fixation of the sliding plate.

[0010] As a further improvement of this utility model, the forward tilting distance of the upper and lower guide rail grooves is the same as the distance between the sliding plate and the fixed plate in the sliding state. Using this technical solution, when the guide rail shaft and switch shaft reach the end of the forward tilt of the upper and lower guide rail grooves, the sliding plate and the fixed plate are on the same plane.

[0011] As a further improvement of this utility model, both the upper and lower guide rail grooves include a straight guide rail and an inclined guide rail parallel to the fixed plate, and the upper and lower guide rail grooves are connected by an arc-shaped guide rail. Using this technical solution, the sliding of the sliding plate is smoother.

[0012] As a further improvement of this utility model, the upper guide rail groove includes a first upper guide rail groove and a second upper guide rail groove of the same shape, and there is one lower guide rail groove. The positions of the first upper guide rail groove and the lower guide rail groove correspond to the positions of the first upper guide rail groove, and the second upper guide rail groove is located behind the first upper guide rail groove and is offset from the first upper guide rail groove. The sliding plate is connected to the first upper guide rail groove through a first guide rail shaft, and the sliding plate is connected to the second upper guide rail groove through a second guide rail shaft. This technical solution makes the sliding plate more stable during sliding and less prone to shaking.

[0013] As a further improvement of this utility model, the first guide rail shaft, the second guide rail shaft, and the switch shaft form a triangular structure. This technical solution, with the first guide rail shaft connected to the upper part of the back of the sliding plate and the second guide rail shaft connected to the lower part of the back of the sliding plate forming a triangle, results in the most stable structure.

[0014] As a further improvement of this utility model, the switch shaft is provided with a handle for pulling or pushing. This technical solution facilitates operation.

[0015] As a further improvement of this utility model, a storage slot is provided on the lower guide rail plate. This technical solution allows for convenient storage of stationery and other teaching supplies, facilitating teacher access and improving ease of use.

[0016] As a further improvement of this utility model, the frame includes two side plates, which are respectively connected to the upper guide rail plate and the lower guide rail plate.

[0017] As a further improvement of this utility model, rubber pads are provided at the edges of both the sliding plate and the fixed plate. This technical solution allows the rubber pads to act as a buffer, helping to prevent accidental impacts by students in the classroom and avoiding injury.

[0018] As a further improvement of this utility model, the frame is mounted on a wall, and a display screen is installed on the wall. The display screen is located to the side of the fixed plate and behind the sliding plate. When the sliding plate slides behind the fixed plate, the display screen can be exposed.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] Firstly, using the technical solution of this utility model, when the worker pushes the switch shaft upward in the locked state of the sliding plate, the sliding plate can be unlocked into a movable state. Through the limiting effect of the upper and lower guide rail plates, the guide rail shaft of the sliding plate can slide in the length direction of the guide rail. When the sliding plate is in the unlocked state and located on the side close to the fixed plate, pulling down the switch shaft locks the sliding plate, and the two plates can achieve a seamless connection between the two surfaces. The structure is simple, making the blackboard aesthetically pleasing and practical, and also solving the problem of dust accumulation and cleaning difficulties at the joint.

[0021] Secondly, in the technical solution of this utility model, the locking mechanism on the back of the sliding plate adopts a gear and rack meshing design. The gear drives the upper and lower connecting rods, which are then engaged in the groove by a baffle, thereby achieving a firm lock between the sliding plate and the fixed plate. This design not only ensures the stability of the sliding plate's position but also allows for locking or unlocking via a switch shaft, making it convenient to use.

[0022] Third, in the technical solution of this utility model, the upper and lower guide rail plates help to keep the sliding plate parallel to the wall and facilitate the movement of the sliding plate along the guide rails; the locking mechanism includes a fixed track and a locking sliding plate, and the sliding plate is connected to the guide rail grooves of the upper and lower guide rail plates, allowing it to slide along the fixed track. The switch shaft design facilitates manual force application by the operator, making the pushing or locking operation of the sliding plate smoother, lowering the barrier to entry, suitable for various users, and providing a better user experience.

Detailed Implementation

[0032] The preferred embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] like Figures 1-3 , Figures 6-7 As shown, a sliding coplanar blackboard includes a frame, a fixed plate 3, and a sliding plate 5. The frame includes an upper guide rail plate 2 and a lower guide rail plate 1. The upper and lower ends of the fixed plate 3 are fixedly connected to the upper guide rail plate 2 and the lower guide rail plate 1, respectively. The upper guide rail plate 2 and the lower guide rail plate 1 are respectively provided with parallel upper guide rail grooves and lower guide rail grooves 15 of the same shape. A guide rail shaft that mates with the upper guide rail groove is provided on the upper back of the sliding plate 5. A locking mechanism is provided on the back of the sliding plate 5. The locking mechanism includes a gear 8, a vertically arranged rack 7, an upper connecting rod 9, a lower connecting rod 10, and a switch shaft 6. The gear 8 is located on one side of the rack 7 and meshes with the rack 7. One end of the upper connecting rod 9 and one end of the lower connecting rod 10 are respectively connected to the gear 8 at opposite positions. The other end of the upper connecting rod 9 extends upward and connects to the upper baffle 11, and the other end of the lower connecting rod 10 extends downward and connects to the lower baffle 12. One end of the switch shaft 6 is fixedly connected to one end of the rack 7, and the switch shaft 6 is slidably connected to the lower guide rail groove 15. The upper baffle 11 and the lower baffle 12 are located behind the sliding plate 5. The upper guide rail plate 2 and the lower guide rail plate 1 are respectively provided with upper baffle groove 16 and lower baffle groove 17 that engage with the upper baffle 11 and the lower baffle 12. The upper guide rail groove and the lower guide rail groove 15 are inclined forward at the middle position of the upper guide rail plate 2 and the lower guide rail plate 1. The forward inclination distance of the upper guide rail groove and the lower guide rail groove 15 is the same as the distance between the sliding plate 5 and the fixed plate 3 in the sliding state. The sliding plate 5 and the fixed plate 3 are rectangular. When the sliding plate 5 reaches the position where it docks with the fixed plate 3, the switch shaft 6 is pulled to drive the rack 7 to move, which in turn drives the upper connecting rod 9 and the lower connecting rod 10 to move through the gear 8. This, in turn, drives the upper baffle 11 and the lower baffle 12 to move up and down respectively. When the upper baffle 11 and the lower baffle 12 are engaged with the upper baffle groove 16 and the lower baffle groove 17 respectively, the sliding plate 5 and the fixed plate 3 are on the same plane and their sides are close together.

[0034] The frame is mounted on the wall, and a display screen 18 is installed on the wall. The display screen 18 is located to the side of the fixed plate 3 and behind the sliding plate 5. When the sliding plate 5 slides behind the fixed plate 3, the display screen 18 is exposed. When the sliding plate 5 slides in front of the display screen 18 and is seamlessly connected to the fixed plate 3 on the same plane, the display screen 18 is obscured.

[0035] In this embodiment, the upper guide rail groove includes a first upper guide rail groove 13 and a second upper guide rail groove 14 with the same shape. There is one lower guide rail groove 15. The positions of the first upper guide rail groove 13 and the lower guide rail groove 15 correspond. The second upper guide rail groove 14 is located behind the first upper guide rail groove 13 and is offset from it (offset on the horizontal plane). The sliding plate 5 is connected to the first upper guide rail groove 13 via a first guide rail shaft, and to the second upper guide rail groove 14 via a second guide rail shaft. The first guide rail shaft, the second guide rail shaft, and the switch shaft 6 form a triangular structure, making the sliding plate 5 less prone to tilting and wobbling, resulting in the most stable structure.

[0036] Furthermore, both the upper guide rail groove and the lower guide rail groove 15 include a straight guide rail and an inclined guide rail parallel to the fixed plate 3, and the upper guide rail groove and the lower guide rail groove 15 are connected by an arc-shaped guide rail.

[0037] Furthermore, the switch shaft 6 is provided with a handle for pulling or pushing, which facilitates operation.

[0038] Furthermore, the lower guide rail plate 1 is provided with a storage slot. This design allows for convenient storage of stationery and other teaching supplies, facilitating teacher access and improving usability.

[0039] Furthermore, the frame includes two side plates 4, which are respectively connected to the upper guide rail plate 2 and the lower guide rail plate 1.

[0040] Furthermore, rubber pads are provided at the edges of both the sliding plate 5 and the fixed plate 3, which can act as a buffer to prevent students from accidentally bumping into them and avoid causing injury.

[0041] Using this technical solution, when the sliding plate 5 reaches the closed position, pulling down the switch shaft 6 causes the switch shaft 6 to connect to the rack 7, which in turn meshes with the gear 8. The rack 7 forces the gear 8 to rotate, which in turn forces the upper connecting rod 9 on the gear 8 to move upwards and the lower connecting rod 10 to move downwards. This causes the upper baffle 11 to move upwards and the lower baffle 12 to move downwards, locking them into the upper baffle groove 16 and the lower baffle groove 17. This achieves the sliding plate 5 and the fixed plate 3 being close together on the same plane and locked in place, resulting in a seamless blackboard effect. When it is necessary to unlock the sliding plate 5, pushing the switch shaft 6 upwards reverses the above actions, unlocking the sliding plate 5 and allowing it to be pushed to expose the display screen 18.

[0042] The upper guide rail plate 2 and the lower guide rail plate 1 help keep the sliding plate 5 parallel to the wall. The sliding plate 5 is slidably connected to the guide rail of the upper guide rail plate 2 via a guide rail shaft, and to the guide rail of the lower guide rail plate 1 via a switch shaft 6, allowing it to slide along the rails. The switch shaft 6 facilitates manual force application by the operator, making the pushing or locking operation of the sliding plate 5 smoother, lowering the barrier to entry, and making it suitable for various users.

[0043] The technical solution of this embodiment can achieve the same-plane docking of the sliding plate 5 and the fixed plate 3, solving the problems of dust accumulation and cleaning difficulties at the splicing point; moreover, it is aesthetically pleasing, easy to operate, and has good stability.
