In primary and secondary school information technology teaching, practical operation is the core teaching link, but the current teaching mode has significant limitations: generally, only one computer room is equipped in middle schools. When the computer room is occupied or cross-class teaching is required, teachers and students can only rely on traditional written teaching, resulting in the disconnection between theory and practice and greatly reducing the teaching effect.
[0003] In response to the above problems, the prior art, such as the utility model patent with the authorization announcement number CN216053377U, proposes an information technology teaching equipment for primary and secondary schools. Through the design of a push rod and universal wheels, the equipment can be flexibly moved, solving the problem of insufficient computer room space; at the same time, a height adjustment mechanism composed of a support rod, a round hole and a fixing pin is set to adapt to users of different heights. In actual operation, it is necessary to manually pull out the fixing pin, move the equipment to the target height and then insert the fixing pin. The whole process requires multiple bending operations and relies on manual precise control, which is time-consuming and laborious. Especially in the scenarios of frequent adjustment or multiple users, the efficiency is low, and it is difficult to meet the needs of quickly adapting to different users in the teaching process.
[0004] Therefore, this application provides an information technology teaching equipment for primary and secondary schools to solve the above problems. Summary of the Invention

[0021] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0022] Embodiment 1 This embodiment provides an information technology teaching device for primary and secondary schools. As Figures 1-6 shown, the teaching device includes a base 1, a teaching computer device 2 arranged on the base 1, and a height adjustment component 3 for driving the teaching computer device 2 to move up and down; In order to not only be able to store the teaching computer device 2 but also be able to adjust its height: a storage groove 11 for storing the teaching computer device 2 is provided on the base 1, and the height adjustment component 3 is arranged in the storage groove 11; the storage groove 11 on the base 1 can store the teaching computer device 2, preventing the device from being exposed to the external environment, effectively preventing dust pollution and bump damage; at the same time, the storage groove 11 provides an installation space for the height adjustment component 3, enabling the device to be completely retracted into the groove when not in use, saving the teaching site space and improving the safety and service life of the device. When the teaching computer device 2 needs to be used, the height adjustment component 3 drives the device to rise from the storage groove 11; when not in use, the device descends into the storage groove 11 through the height adjustment component 3, and the groove body of the storage groove 11 forms a surrounding protection for the device, realizing the function switching of "storage - deployment".
[0023] The height adjustment assembly 3 includes a driving member 31 and a hinge 32, wherein the driving member 31 is used to drive the hinge 32 to expand or close; the driving member 31 includes a lifting frame 311, a bidirectional screw rod 312 rotatably plugged into the lifting frame 311, a threaded sleeve 313 symmetrically threadedly sleeved on the bidirectional screw rod 312, a driving support rod 314 symmetrically hinged at the upper and lower ends of the threaded sleeve 313, and a driving motor 315 for driving the bidirectional screw rod 312 to rotate; the hinge 32 is provided with two groups, and the two groups of hinges 32 are symmetrically hinged at At the upper and lower ends of the lifting frame 311, each group of hinges 32 is provided with two, and the hinges 32 include a first hinge plate 321 and a second hinge plate 322 which are hinged to each other. The end of the first hinge plate 321 away from the second hinge plate 322 is hinged to the lifting frame 311, the middle part of the first hinge plate 321 is hinged to the driving support rod 314, and the end of the second hinge plate 322 away from the first hinge plate 321 is hinged with a fixed plate 323. The two fixed plates 323 are respectively fixedly connected to the inner bottom wall of the storage slot 11 and the lower end of the teaching computer equipment 2. Through the mechanical linkage of the driving member 31 (bidirectional screw rod 312, threaded sleeve plate 313, driving support rod 314, driving motor 315) and the hinge member 32 (first hinge plate 321, second hinge plate 322), the teaching computer device 2 can be automatically lifted and adjusted in height without manual plugging and unplugging of the fixing pin, which solves the problem of time-consuming and labor-intensive manual adjustment in the prior art, and is convenient to operate and efficient; the two sets of hinge members 32 are symmetrically arranged, which can stably support the equipment, adapt to the different height differences of primary and secondary school students, and improve the comfort of use. Lifting process: Start the driving motor 315, which drives the bidirectional screw rod 312 to rotate clockwise, so that the threaded sleeve plates 313 on both sides move away from the center, push the driving support rod 314 to expand outward, and then drive the first hinge plate 321 to rotate around the hinge point with the lifting frame 311, push the hinge ends of the first hinge plate 321 and the second hinge plate 322 to gradually open, and finally push the teaching computer device 2 upward from the storage slot 11 and adjust it to the target height. Storage process: the driving motor 315 reverses, the bidirectional screw rod 312 rotates counterclockwise, the threaded sleeve plate 313 moves toward the center, pulling the driving support rod 314 to retract inward, so that the hinged ends of the first hinge plate 321 and the second hinge plate 322 are folded, and the device then descends into the storage groove 11.
[0024] In order to facilitate the installation of the drive motor 315: the drive motor 315 is fixedly plugged into one end of the lifting frame 311, and the output end of the drive motor 315 is fixedly connected to the shaft rod at one end of the bidirectional screw rod 312. The transmission structure is simplified, the space occupied by the motor is reduced, the overall structure of the height adjustment component 3 is more compact, and the utilization rate of the internal space of the equipment is improved. The drive motor 315 serves as a power source, and directly drives the bidirectional screw rod 312 to rotate through the shaft rod, converting the rotational motion of the motor into the linear motion of the threaded sleeve plate 313, thereby driving the hinge 32 to expand / close, without the need for additional transmission components, and the power transmission is efficient and direct.
[0025] To ensure the stability of the articulated ends of the first articulated plate 321 and the second articulated plate 322: On both sides of one end of the first articulated plate 321 close to the second articulated plate 322, connecting plates 324 are articulated with the second articulated plate 322. At the articulated ends of the first articulated plate 321 and the second articulated plate 322, meshing gears 325 are arranged through rotating shafts. The articulated ends of the first articulated plate 321 and the second articulated plate 322 are connected by the connecting plates 324 and the meshing gears 325. The meshing transmission of the gears 325 ensures the synchronism and accuracy of the movements of the two, preventing dislocation or shaking of the articulated ends during the movement process; the connecting plates 324 enhance the structural strength of the articulated part, improve the stability of the articulated part 32, and ensure the smooth and reliable height adjustment process. When the first articulated plate 321 and the second articulated plate 322 rotate relative to each other, the gears 325 at their articulated ends mesh with each other, restricting the relative movement trajectories of the two, enabling the two to only rotate synchronously around the articulated axis and ensuring that the opening or folding angles are the same; the connecting plates 324 form supports on both sides of the gears 325, further fixing the positions of the articulated ends and preventing shaking.
[0026] To further improve the stability of the articulated ends of the first articulated plate 321 and the second articulated plate 322: One end of the first articulated plate 321 close to the second articulated plate 322 is articulated with a first support plate 326, and one end of the second articulated plate 322 close to the first articulated plate 321 is articulated with a second support plate 327 that is mutually articulated with the first support plate 326. The first support plate 326 and the second support plate 327 are respectively articulated on the first articulated plate 321 and the second articulated plate 322 and are mutually articulated to form a rhombus support structure, providing additional support for the opening angle of the articulated part 32, further enhancing the stability of the articulated ends, preventing the equipment from tilting or jamming due to uneven force during the lifting process, and improving the reliability of the height adjustment mechanism. When the first articulated plate 321 and the second articulated plate 322 open, the first support plate 326 and the second support plate 327 unfold with the rotation of the two, forming a stable rhombus support structure, restricting the maximum opening angle of the two and dispersing the force; when the articulated part 32 folds, the support plates contract synchronously with the articulated plates, not affecting the storage process.
[0027] To facilitate the shielding of the opening of the storage slot 11: A shielding plate 21 is provided at the upper end of the teaching computer device 2, and a silica gel pad 22 is fixedly connected to the lower edge side of the shielding plate 21. The shielding plate 21 at the upper end of the teaching computer device 2 can completely cover the opening of the storage slot 11 when the device is stored, preventing dust and debris from entering the slot; the silica gel pad 22 is provided at the lower end of the shielding plate 21, which can not only buffer the collision between the shielding plate 21 and the base 1, reduce noise and wear, but also fill the gap between the two, improve the sealing effect, and further enhance the dust-proof ability. When the device is stored in the storage slot 11, the shielding plate 21 descends to the surface of the base 1 along with the device, and the silica gel pad 22 contacts the base 1, filling the gap through its own elastic deformation to form a seal; when the device rises, the shielding plate 21 rises synchronously with the device, exposing the opening of the storage slot 11, without affecting the use of the device.
[0028] To facilitate the storage of the keyboard: A keyboard drawer 4 is inserted in the front of the base 1, and a handle 41 is provided on the keyboard drawer 4. The keyboard drawer 4 at the front of the base 1 provides a dedicated storage space for the keyboard, avoiding damage or loss caused by the keyboard being exposed, and keeping the teaching equipment clean; the handle 41 facilitates the teachers and students to push and pull the drawer, improving the convenience of use. When the keyboard is needed, the keyboard drawer 4 is pulled out from the front of the base 1 through the handle 41 to take out the keyboard; after use, the keyboard is put back into the drawer and pushed into the base 1 to realize the convenient storage and access of the keyboard.
[0029] To facilitate the movement of the teaching equipment: Two movable casters 12 with self-locking functions are symmetrically and fixedly installed on the front side of the lower end of the base 1, and two fixed casters 13 are symmetrically and fixedly installed on the rear side of the lower end of the base 1. The two movable casters 12 (with self-locking functions) at the lower end of the base 1 can rotate freely 360°, facilitating the flexible adjustment of the movement direction of the device; the two fixed casters 13 can only move in a straight line, providing stable support and guidance. The cooperation of the two enables the device to not only turn easily but also maintain the stability of straight-line movement, meeting the requirements of different teaching venues. When pushing the device, the movable casters 12 rotate in any direction through the steering bearing, cooperating with the straight-line guidance of the fixed casters 13, enabling the device to move flexibly; when the position of the device needs to be fixed, the wheel body is locked through the self-locking function of the movable casters 12 to prevent sliding.
[0030] Embodiment 2 Different from Embodiment 1, in order to facilitate the adjustment of the tilt angle of the teaching computer device 2: an angle adjustment mechanism 5 is provided at the bottom of the teaching computer device 2. The angle adjustment mechanism 5 includes a worm and worm gear transmission assembly 51. A drive rod 52 is fixedly inserted through the worm shaft of the worm and worm gear transmission assembly 51. First support plates 53 fixedly connected to the fixed plate 323 are rotatably sleeved at both ends of the drive rod 52. Second support plates 54 fixedly connected to the lower end of the teaching computer device 2 are symmetrically and fixedly sleeved on the drive rod 52. A handle 55 is fixedly connected to the worm shaft of the worm and worm gear transmission assembly 51. The angle adjustment mechanism 5 realizes stepless adjustment of the tilt angle of the teaching computer device 2 through the worm and worm gear transmission assembly 51, which can adapt to the viewing angles of students of different heights, avoid visual fatigue caused by improper screen angles, and improve the comfort and interactivity of the teaching process; the self-locking characteristic of the worm and worm gear can ensure that the device remains stable after being adjusted to any angle and prevent accidental shaking. Rotate the handle 55 to drive the worm shaft to rotate. The worm drives the worm wheel to rotate. The worm shaft drives the second support plate 54 to rotate through the drive rod 52, thereby adjusting the tilt angle of the teaching computer device 2; the meshing of the worm and worm gear has a self-locking function. When the handle 55 stops rotating, the device angle is fixed without an additional locking device.
