Description

Technical Field

[0001] This utility model relates to the field of teaching equipment technology, and in particular to a teaching demonstration device for talent training. Background Technology

[0002] Talent training refers to the process of educating and training talents. It aims to enable selected talents to become specialized talents required for various occupations and positions through education and training. The training takes many forms, including systematic education, part-time education, full-time or part-time training courses, seminars, etc. Corresponding teaching and demonstration devices are needed in the talent training process.

[0003] For example, utility model patent application number 202021820517.2 discloses a demonstration and teaching device for training, including a support frame and a display mounted on the support frame. The display is slidably connected to the support frame along its height and fixed by an adjustable locking component. The adjustable locking component includes a movable sleeve that is slidably sleeved on the support frame. A support base for supporting the bottom of the display is connected to the movable sleeve. A locking structure that is locked and fixed to the support frame is also connected to the movable sleeve.

[0004] Based on existing technology, most teaching demonstration devices used for talent training have a simple structure, possessing only a single lifting function and lacking the ability to tilt and adjust the display. This results in the inability to adjust the display angle according to actual usage needs, leading to low applicability. Furthermore, the fixed structure of the device body makes it inconvenient to clamp onto displays of different sizes, thus limiting its applicability to teaching demonstrations on displays of various sizes and causing inconvenience in use. Therefore, this utility model proposes a teaching demonstration device for talent training to solve the problems existing in the prior art. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to propose a teaching demonstration device for talent training, which solves the problems that existing teaching demonstration devices for talent training do not have the function of tilting and adjusting the display, thus making it impossible to adjust the display angle according to actual use needs, and that the fixed structure of the device body makes it inconvenient to clamp displays of different sizes.

[0006] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: a teaching and display device for talent training, including a base, a support plate fixed at the top of the base, an L-shaped support frame slidably provided on the inner side of the support plate, the L-shaped support frame and the support plate being positioned and locked together by a first positioning mechanism, a mounting plate hinged to the front end of the L-shaped support frame, an tilt adjustment mechanism adapted to the mounting plate provided on the L-shaped support frame, extension plates slidably connected to the four side walls of the mounting plate, the extension plates and the mounting plate being positioned and locked together by a second positioning mechanism, a clamping mechanism fixed on the front side of the extension plate away from the mounting plate, and a display body clamped on the front side of the mounting plate by the clamping mechanism.

[0007] A further improvement is that the tilt adjustment mechanism includes a first lead screw threaded through an L-shaped support frame and driven to rotate by a turntable, and a push plate rotatably connected to one end of the first lead screw near the mounting plate. The side of the push plate away from the first lead screw is symmetrically fixed with pulleys that abut against the mounting plate.

[0008] A further improvement is that a limiting slide rod is symmetrically fixed on the side of the push plate away from the pulley, and the end of the limiting slide rod away from the push plate slides through the L-shaped support frame.

[0009] A further improvement is that the clamping mechanism includes an L-shaped support plate fixed to the front of the extension plate and a second lead screw threaded through the L-shaped support plate. The end of the second lead screw near the display body is rotatably connected to a pressure plate that slides against the L-shaped support plate, and the end of the second lead screw away from the pressure plate is fixed with a knob.

[0010] A further improvement is that the first positioning mechanism includes a frame fixed to the outer rear wall of the support sleeve, a sliding through frame, and a positioning pin for the support sleeve. The outer rear wall of the L-shaped support frame is provided with equidistant insertion holes adapted to the positioning pin, and a pull ring is fixed to one end of the positioning pin located outside the frame.

[0011] A further improvement is that a baffle is fixed to one side of the positioning pin inside the frame, and a limiting spring that is movably sleeved on the positioning pin is fixed between the side of the baffle away from the support sleeve and the inner wall of the frame away from the support sleeve.

[0012] A further improvement is that the second positioning mechanism includes a positioning bolt threaded through the rear side of the mounting plate and corresponding to the position of the extension plate, and a positioning hole opened on the rear side wall of the extension plate, wherein the positioning holes are equidistantly distributed on the extension plate.

[0013] The beneficial effects of this utility model are as follows: This utility model includes a base, and a mounting plate for clamping the display body is hinged to the front end of an L-shaped support frame. A tilt adjustment mechanism for driving the mounting plate to rotate and tilt is provided on the L-shaped support frame, so that the device has the function of tilting the display body. Thus, the teaching display angle can be adjusted according to actual use needs, and the applicability is high. Furthermore, by slidingly connecting telescopic and adjustable extension plates on the four sides of the mounting plate, and setting a clamping mechanism on the extension plate to clamp and fix the display body to the front of the mounting plate, the device is easy to adjust and can clamp display bodies of different sizes, thus making it suitable for teaching displays of different sizes.

[0022] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0023] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, this embodiment provides a teaching demonstration device for talent training, including a square base 1 and a support plate 2 fixed to the top center of the base 1 by bolts. Universal wheels are fixed to the four corners of the bottom of the base 1 by bolts to facilitate movement and transfer of the device. An L-shaped support frame 3 with an L-shaped design slides within the inner side of the support plate 2. The L-shaped support frame 3 and the support plate 2 are positioned and engaged by a first positioning mechanism, facilitating the adjustment and fixation of the L-shaped support frame 3. A mounting plate 4 is hinged to the front end of the L-shaped support frame 3 via a hinge, allowing the mounting plate 4 to rotate and tilt along the hinge. A tilt adjustment mechanism is provided on the L-shaped support frame 3, and this mechanism is adapted to the mounting plate 4 to drive the mounting plate 4 to rotate and tilt along the hinge. The mounting plate 4 has four sliding grooves on its interior (top, bottom, left, and right sides), and sliding connections within these grooves are also present. An extension plate 5 is attached, extending beyond the mounting plate 4 and positioned and engaged with the mounting plate 4 via a second positioning mechanism. A clamping mechanism is fixed on the front side of the extension plate 5 away from the mounting plate 4. A display body 6 for displaying teaching content is provided on the front side of the mounting plate 4, and the display body 6 is clamped and fixed to the front side of the mounting plate 4 by the clamping mechanism. The mounting plate 4 for clamping the display body 6 is hinged to the front end of the L-shaped support frame 3, and a tilt adjustment mechanism for driving the mounting plate 4 to rotate and tilt is provided on the L-shaped support frame 3, thereby enabling the device to tilt the display body 6. By sliding the extendable and adjustable extension plates 5 on the four sides of the mounting plate 4 respectively, and clamping mechanisms are provided on the extension plates 5 to clamp and fix the display body 6 to the front side of the mounting plate 4, display bodies 6 of different sizes can be clamped.

[0024] The tilt adjustment mechanism includes a first lead screw 8 and a push plate 9. The first lead screw 8 is threaded through the L-shaped support frame 3. The rear end of the first lead screw 8 is fixed to a turntable 7 by bolts and is driven to rotate by the turntable 7. The front end of the first lead screw 8 is rotatably connected to the push plate 9 by a bearing. The front side wall of the push plate 9 is fixed with pulleys 10 that are symmetrically distributed on the left and right sides by bolts. The pulleys 10 abut against the back of the mounting plate 4. By rotating the turntable 7, the first lead screw 8 is driven to rotate forward, which can drive the push plate 9 and pulleys 10 to move forward. During the forward movement of the pulleys 10, the lower part of the mounting plate 4 is lifted, thereby realizing the counterclockwise tilt adjustment of the mounting plate 4 (left view). The rear side wall of the push plate 9 is fixed with a limiting slide rod 11 that is symmetrically distributed on the left and right sides and slides through the L-shaped support frame 3 by bolts. The limiting slide rod 11 plays a limiting role for the push plate 9, making it more stable during movement.

[0025] The clamping mechanism includes an L-shaped support plate 12 and a second lead screw 13. The L-shaped support plate 12 is fixed to the front of the extension plate 5 by bolts. The second lead screw 13 is threaded through the front side wall of the L-shaped support plate 12. The end of the second lead screw 13 near the monitor body 6 is rotatably connected to a pressure plate 14 through a bearing. The pressure plate 14 slides against the inner side wall of the L-shaped support plate 12. The end of the second lead screw 13 away from the pressure plate 14 is fixed to a knob 15 by bolts. By rotating the knob 15, the second lead screw 13 is driven to rotate backward, thereby causing the pressure plate 14 to move towards the extension plate 5, thus clamping and fixing the monitor body 6 in conjunction with the mounting plate 4.

[0026] The first positioning mechanism includes a frame 16 and a positioning pin 17. The frame 16 is fixed to the rear outer wall of the support sleeve 2 by bolts. The positioning pin 17 slides through the frame 16 and the support sleeve 2. The rear outer wall of the L-shaped support frame 3 has equally spaced insertion holes 18, which are adapted to the positioning pin 17. The L-shaped support frame 3 is positioned and fixed by inserting the positioning pin 17 into the insertion hole 18. A pull ring is welded to one end of the positioning pin 17 outside the frame 16 to facilitate the user to pull out the pin.

[0027] A baffle 19 is fixed to one side of the positioning pin 17 inside the frame 16. A limiting spring is fixed to the side of the baffle 19 away from the support sleeve 2 and is movably sleeved on the positioning pin 17. The end of the limiting spring away from the baffle 19 is fixedly connected to the inner wall of the frame 16 away from the support sleeve 2. The limiting spring provides an elastic push-out force to the baffle 19, so that the positioning pin 17 can be automatically inserted into the insertion hole 18.

[0028] The second positioning mechanism includes positioning bolts 20 and positioning holes 21. The positioning bolts 20 are provided in four sets and are threaded through the four sides of the rear sidewall of the mounting plate 4. The four sets of positioning bolts 20 correspond to the positions of the four sets of extension plates 5. The positioning holes 21 are equidistantly opened on the rear sidewall of the extension plate 5. The positioning and fixing of the extension plate 5 is achieved by screwing the positioning bolts 20 into the positioning holes 21.

[0029] When it is necessary to display teaching content during talent training, the device is moved to the talent training teaching site (usually a lecture hall). Then, according to the actual needs, the L-shaped support frame 3 is slidably adjusted to an appropriate height on the support plate 2, and the first positioning mechanism is used to fix it in place to adjust the display height. Then, the display body 6 used to display the teaching content is placed on the front of the mounting plate 4. At the same time, according to the specifications and dimensions of the display body 6, the extension plates 5 on the four sides of the mounting plate 4 are slidably adjusted to appropriate positions, and the display body 6 is clamped and fixed to the front of the mounting plate 4 using the clamping mechanism. Then, the second positioning mechanism is used to fix each extension plate 5 in place to install the display body 6. Then, the tilt adjustment mechanism is used to drive the mounting plate 4 to rotate counterclockwise along its hinge with the L-shaped support frame 3 and tilt (left view) to an appropriate angle. While the mounting plate 4 rotates and tilts, it drives the display body 6 clamped on its front to rotate synchronously, thus adjusting the teaching display angle. Finally, the display body 6 is turned on to display the talent training teaching content to the audience.
