Description

Technical Field

[0001] This utility model relates to the field of multimedia teaching technology, specifically to a lock that is installed on an electronic interactive blackboard. Background Technology

[0002] Multimedia has gradually become widespread in ordinary classrooms, making teaching methods more convenient and diverse. Current multimedia formats generally use projection whiteboards and touch-screen TVs. While teachers and students enjoy diversified teaching methods, they are also troubled by hardware issues, such as the impact of light pollution on students' eyesight and the physical exertion of pushing and pulling the blackboard up and down on teachers. To further improve teaching quality and avoid the shortcomings of existing equipment, interactive blackboards are gradually being adopted in existing multimedia classrooms. These blackboards can easily switch between chalk writing and multimedia applications, while simultaneously providing different functions such as writing and touch control.

[0003] Existing interactive blackboards typically include a touch-screen TV and a fixed blackboard. To protect the TV, a movable panel is also added. When the TV is not in use, the movable panel moves to the front of the TV, thus protecting it. When the TV needs to be used, the movable panel is moved to the front of the fixed blackboard, significantly improving the ease of operation and use.

[0004] However, during use, the movable board of the aforementioned products is prone to shifting, affecting the product's stability and safety. To avoid this problem, some designs incorporate locking devices between the movable board and the fixed blackboard. For example, a protective device for a smart blackboard based on a spring-loaded push-pull door lock structure is disclosed in CN112396877A. This structure cannot lock the movable board independently; that is, it cannot be locked when the movable board is in front of the fixed blackboard. Furthermore, it lacks aesthetic appeal. Another approach involves installing a locking device below the movable board, such as a sliding locking device for a sliding blackboard disclosed in CN206644541U. This structure requires more components, including a motor, resulting in higher operating costs. Utility Model Content

[0005] The purpose of this invention is to provide a lock that can be installed on an electronic interactive blackboard, solving the problems of existing technologies that cannot lock the movable board individually, have insufficient stability, and have overly complex structures for locking the movable board individually, resulting in high operating costs.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] A lock for installation on an interactive electronic blackboard includes a mounting plate and a locking adjustment assembly. The locking adjustment assembly includes a fixed base, a rotating base, and a lock body. The fixed base is sleeved on one side of the rotating base and connected to the mounting plate. An installation gap is formed between the side of the rotating base and the mounting plate. One side of the fixed base has a mounting groove. A limit plate and a latch are provided in the mounting groove. An elastic element is provided between the upper end of the latch and the upper inner wall of the mounting groove. The lower end of the latch extends out of the mounting groove and the rotating base in sequence. A connecting piece is also provided between the rotating base and the latch. The lock body includes a lock shell and a lock cylinder. One end of the lock shell is sleeved from the other side of the rotating base and passes through the mounting groove. One end of the lock cylinder is sleeved into the lock shell, and the other end is provided with a key. The upper end of the limit plate is limited and connected to the lock cylinder, and the lower end is limited and connected to the latch. The limit plate moves up and down along the mounting groove by the key to lock and unlock the latch.

[0008] Preferably, the rotating base described above is provided with a first mounting shell and a second mounting shell. The first mounting shell is provided with a fixing groove for mounting a fixing seat. A mounting platform is provided between the outer wall of the fixing groove and the inner wall of the first mounting shell. The connecting piece is fixed on the mounting platform. The connecting piece is provided with a positioning post. The latch is provided with a positioning groove corresponding to the positioning post. The opening ring of the first mounting shell is also provided with a first limiting hole. The fixing groove is provided with a limiting notch corresponding to the first limiting hole. The latch passes through the limiting notch and the first limiting hole in sequence. The rotating base reciprocates within the limiting notch and the first limiting hole. The connecting piece drives the latch to move up and down along the first limiting hole.

[0009] Preferably, the lock tongue is provided with a second limiting hole and a groove, and a first limiting post is provided on the limiting plate corresponding to the groove. The upper end of the lock tongue is also formed with an elastic element mounting groove. One end of the lock cylinder is provided with a second limiting post and the other end is provided with a key. A third limiting hole is provided on the limiting plate corresponding to the second limiting post.

[0010] Preferably, the aforementioned fixing base is further provided with a baffle plate, the locking tongue is located between the baffle plate and the limiting plate, and the baffle plate is further provided with an arc-shaped concave piece, which is located on one side of the elastic element.

[0011] Preferably, the mounting groove described above has a first groove and a second groove, one end of the lock housing has a connecting seat, and the connecting seat passes through the mounting groove and is embedded in the first groove, the limiting plate is movably located in the connecting seat, and the lock tongue is movably located in the second groove.

[0012] Preferably, the aforementioned fixing base is provided with three fixing ends, the mounting plate is connected to the fixing ends by screws, the connecting piece is provided with an arc-shaped notch, the connecting piece is connected to the mounting platform by two screws, and the arc-shaped notch moves along one of the fixing ends.

[0013] Preferably, the second mounting housing is provided with a detachable protective cover.

[0014] Preferably, the mounting plate described above is also provided with a television sensor.

[0015] This utility model has the following beneficial effects: The lock of this utility model is installed through the cooperation of the fixed base, the rotating base and the lock body, resulting in a compact structure. It eliminates the need for working parts on the mounting plate. Because the mounting plate is located between the TV and the movable plate, the simplification of the mounting plate reduces the installation space. When the movable plate is in front of the TV, the gap between the movable plate and the fixed black plate is smaller, preventing the entry of dust and other foreign objects, providing more effective protection for the TV carrier and improving the overall service life of the product. Simultaneously, the limiting rotation causes the lock tongue to move elastically up and down, realizing the locking and unlocking process of the lock on the movable plate. The operation is simple and the working process is stable. The addition of a key control prevents the risk of accidental unlocking, thereby effectively improving the product's usability, security and service life. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-5 As shown, a lock installed on an interactive whiteboard includes a mounting plate 1 and a locking adjustment assembly. The locking adjustment assembly includes a fixed base 2, a rotating base 3, and a lock body. The fixed base 2 is sleeved on one side of the rotating base 3 and is connected to the mounting plate 1. An installation gap is formed between the side of the rotating base 3 and the mounting plate 1. One side of the fixed base 2 is provided with a mounting groove 201. A limit plate 4 and a locking tongue 5 are provided in the mounting groove 201. An elastic element 6 is provided between the upper end of the locking tongue 5 and the upper inner wall of the mounting groove 201. The lower end of the latch 5 extends out of the mounting groove 201 and the rotating seat 3 in sequence. A connecting piece 7 is also provided between the rotating seat 3 and the latch 5. The lock body includes a lock shell 8 and a lock cylinder 9. One end of the lock shell 8 is inserted into the mounting groove 201 from the other side of the rotating seat 3. One end of the lock cylinder 9 is inserted into the lock shell 8, and the other end is provided with a key 10. The upper end of the limiting plate 4 is limited and connected to the lock cylinder 9, and the lower end is limited and connected to the latch 5. The limiting plate 4 is controlled by the key 10 to move up and down along the mounting groove 201 to lock and open the latch 5.

[0024] In use, first open the latch 5 with key 10 by rotating key 10. The lock cylinder 9 will move the limiting plate 4 upward, forming a locking state where the latch 5 can move along the limiting plate 4, thus opening the latch 5. Then, rotate the rotating base 3. The rotation of the rotating base 3 will move the connecting piece 7 together, which will move the latch 5 upward, so that the lower end of the latch 5 is unlocked from the mounting frame of the electronic interactive push-pull blackboard (the frame is provided with a lock groove for the latch 5 to be inserted). At this time, the movable plate with the lock installed can be pushed and pulled along the frame. When the movable plate slides to the position of the lock groove in the frame, due to the rebound of the elastic element 6 at the upper end of the latch 5, the latch 5 can be inserted into the lock groove for locking. Finally, rotate key 10 again, and the lock cylinder 9 will move the limiting plate 4 downward, forming a locking state where the latch 5 is pressed by the limiting plate 4, thus locking the latch 5. At this time, the rotating base 3 cannot be rotated. To prevent accidental opening of the lock, key 10 can also be removed.

[0025] The lock of this utility model is compactly structured through the cooperation and installation of the fixed base 2, the rotating base 3, and the lock body. It eliminates the need for working parts on the mounting plate 1. Because the mounting plate 1 is located between the television and the movable plate, its simplification reduces the installation space. When the movable plate is in front of the television, the gap between the movable plate and the fixed base is smaller, preventing the entry of dust and other foreign objects, providing more effective protection for the television carrier, and improving the overall product lifespan. Simultaneously, the limiting rotation causes the locking tongue 5 to move elastically up and down, realizing the locking and unlocking process of the lock on the movable plate. The operation is simple and the working process is stable. The addition of the key 10 further prevents the risk of accidental unlocking, thereby effectively improving the product's usability, security, and lifespan.

[0026] Furthermore, the rotating base 3 is provided with a first mounting shell 301 and a second mounting shell 302. The first mounting shell 301 is provided with a fixing groove 303 for mounting the fixing base 2. A mounting platform 304 is provided between the outer wall of the fixing groove 303 and the inner wall of the first mounting shell 301. The connecting piece 7 is fixed on the mounting platform 304. A positioning post 701 is provided on the connecting piece 7. A positioning groove 501 is provided on the latch 5 corresponding to the positioning post 701. A first limiting hole 305 is also provided on the opening ring of the first mounting shell 301. A limiting notch 306 is provided on the fixing groove 303 corresponding to the first limiting hole 305. The latch 5 passes through the limiting notch 306 and the first limiting hole 305 in sequence. The rotating base 3 reciprocates within the limiting notch 306 and the first limiting hole 305. The connecting piece 7 drives the latch 5 to move up and down along the first limiting hole 305. The above design, the design of the fixing groove 303, allows the fixing seat 2 and the limiting plate 4 and the lock tongue 5 on the fixing seat 2 to be located inside the first mounting shell 301, reducing the overall installation volume of the lock. The design of the first limiting hole 305 and the limiting notch 306 allows the rotating seat 3 to be limited to rotate, preventing excessive rotation and ensuring the effectiveness and stability of the lock.

[0027] Furthermore, the latch 5 is provided with a second limiting hole 502, the second limiting hole 502 is provided with a groove 503, the limiting plate 4 is provided with a first limiting post 401 corresponding to the groove 503, the upper end of the latch 5 is also formed with an elastic element mounting groove 504, one end of the lock cylinder 9 is provided with a second limiting post 901, the other end is provided with a key 10, and the limiting plate 4 is provided with a third limiting hole 402 corresponding to the second limiting post 901.

[0028] In the above design, by turning the key 10, the second limiting post 901 on the lock cylinder 9 can rotate within the third limiting hole 402, thereby driving the limiting plate 4 to move. When the first limiting post 401 is stuck in the groove 403, the lock tongue 5 is in the unlocked state. The rotation of the rotating seat 3 causes the connecting piece 7 to move the lock tongue 5 upward, unlocking it from the blackboard frame and allowing it to move. When the lock needs to be locked at the desired position, the key 10 is turned, and the second limiting post 901 drives the limiting plate 4 downward, causing the first limiting post 401 to disengage from the groove 403 and move until the first limiting post 401 presses against the bottom inner wall of the second limiting hole 502. At this time, the lock tongue 5 cannot move upward and is in the locked state. That is to say, the rotating seat 3 will not be able to rotate, and the entire lock is in a locked state. The design of the elastic element mounting groove 504 can improve the installation and working stability of the elastic element 6, thereby improving the overall stability of the lock.

[0029] Furthermore, a baffle plate 11 is also provided on the fixed base 2, and the locking tongue 5 is located between the baffle plate 11 and the limiting plate 4. The baffle plate 11 is also provided with an arc-shaped concave piece 1101, which is located on one side of the elastic element 6. With the above design, the baffle plate 11 can provide a certain degree of protection for the locking tongue 5, the limiting plate 4, and the elastic element 6, reducing the breakage rate of the components. At the same time, the arc-shaped concave piece 1101 can make the working process of the elastic element 6 more stable.

[0030] Furthermore, a first groove and a second groove are formed within the mounting groove 201. A connecting seat 801 is formed at one end of the lock housing 8, and the connecting seat 801 passes through the mounting groove 201 and is embedded in the first groove. The limiting plate 4 is movably located within the connecting seat 801, and the bolt 5 is movably located within the second groove. This design improves the connection strength and stability between the lock body and the fixed seat 2, and enhances the stability of the operation process.

[0031] Furthermore, the fixed base 2 is provided with three fixed ends 12. The mounting plate 1 is connected to the fixed ends 12 by screws 13. The connecting piece 7 is provided with an arc-shaped notch 702. The connecting piece 7 is connected to the mounting platform 304 by two screws 13, and the arc-shaped notch 702 can move along one of the fixed ends 12. In the above design, the fixed ends 12 are designed to be three in a triangular connection, which can improve the connection stability between the mounting plate 1 and the fixed base 2. The design of the connecting piece 7 and its movement along one of the fixed ends can improve the rotational stability of the rotating base 3.

[0032] Furthermore, a protective cover 14 is detachably provided on the second mounting housing 302. The above design facilitates the installation and removal of the lock body and the rotating base 3, and logos or other markings can be designed on the protective cover 1 to improve the aesthetics of the lock.

[0033] Furthermore, a television sensor is also provided on the mounting plate 1. In the above design, the television sensor is installed in conjunction with the sensor on the television set. For example, using the magnetic component 15, when the moving plate is moved in front of the television, the television screen will automatically turn off and the television will automatically turn off. The specific sensing operation can be achieved using existing sensing technologies in the television field, and will not be elaborated here.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
