Description

Technical Field

[0001] This invention relates to the field of electronic information technology, and in particular to a computer multimedia distance education and training device. Background Technology

[0002] The computer multimedia distance education and training teaching device is a hardware and software combination device that integrates computer technology, multimedia processing technology, and remote communication technology. It consists of a multimedia acquisition and processing module, a remote communication and transmission module, a remote learning and interactive terminal, and a teaching management and control module. Its core objective is to break the limitations of time and space, support two-way and one-way teaching interaction between teachers and students in different locations, transmit course resources and manage learning, and enable learners to receive standardized and visualized multimedia teaching content and complete the entire training process of learning, practice and interaction in a non-site environment.

[0003] Currently, the existing multimedia distance education and training teaching devices have a relatively closed overall structure. When the device is idle for a long time, dust from the external environment will gradually accumulate on the surface of the device, which will seriously affect the user's normal teaching and training experience.

[0004] Meanwhile, during operation, the chassis of multimedia distance education and training teaching devices continuously generates a large amount of heat due to the high-speed operation of internal components. To ensure stable operation, most devices have multiple heat dissipation holes on the chassis to achieve air circulation and heat dissipation. However, these heat dissipation holes generally adopt a long-term open design and lack an effective dust protection structure. External dust will directly enter the chassis through the heat dissipation holes during air convection. Over time, a thick layer of dust will accumulate on the internal components, further aggravating the heat dissipation burden and failure risk of the equipment, and adversely affecting the service life and operational stability of the device. Therefore, it is urgent to develop a computer multimedia distance education and training teaching device. Summary of the Invention

[0005] Purpose of the invention: The purpose of this invention is to provide dust protection for equipment when it is idle, which is a defect that dust tends to accumulate on the surface of the equipment and affects the teaching and training experience.

[0006] Another objective of this invention is to address the problem of dust entering the chassis through air convection due to the long-term open ventilation holes of the chassis, forming a deposit layer on the surface of core components, which exacerbates the heat dissipation burden, increases the risk of failure, and shortens the service life of the device, thereby achieving a balance between heat dissipation and dust prevention functions.

[0007] Technical Solution: A computer multimedia distance education and training teaching device includes a body. Slide grooves are formed on both sides of the body's interior. Sliding blocks are slidably installed inside each of the two slide grooves. A cover is fixedly installed on the opposite sides of the two sliding blocks. Racks are fixedly installed on both sides of the lower surface of the cover. A rotating column is rotatably installed inside the body via a rotating shaft. Two gears are fixedly installed on the outer wall of the rotating column. The upper part of the outer wall of the two gears meshes with the lower part of the outer wall of the two racks. A non-standard gear is fixedly installed on the outer wall of the rotating column, located on the opposite side of the two gears. A fixedly installed... The machine has a threaded rod, and a threaded block is threadedly installed on the outer wall of the threaded rod. The threaded block is located in front of the shaped gear. An operating table is fixedly installed on the upper surface of the threaded block. T-slots are opened on both sides of the machine body and below the rotating column. T-blocks are slidably installed inside the two T-slots. Racks are fixedly installed on opposite sides of the two T-blocks. The upper part of the outer wall of racks meshes with the lower part of the outer wall of the gear. A shielding block is fixedly installed on the lower surface of the two racks. Through-type heat dissipation slots are opened on both sides of the machine body. A chassis is fixedly installed on the lower surface of the machine body. A display screen is provided on the front surface of the machine body.

[0008] Furthermore, a rotating column two is rotatably mounted on the front surface of the machine body via a rotating shaft, a slot is provided on the front surface of the machine cover, the rear end of the rotating column two penetrates into the slot and is fixedly mounted with a locking block, and a rotating valve is fixedly mounted on the front end of the rotating column two.

[0009] Furthermore, a guide groove is provided on the rear surface of the cover, and a guide rod is slidably installed inside the guide groove. The rear end of the guide rod is fixedly connected to the inner rear surface of the body. A spring is fixedly installed on the inner rear surface of the body and the rear surface of the cover, located on the outer wall of the guide rod.

[0010] Furthermore, two abutments are fixedly installed on the lower surface of the cover between the two racks.

[0011] Furthermore, an installation plate is fixedly installed on the rear inner surface of the body, and multiple springs are fixedly installed on the lower surface of the installation plate. The lower ends of the multiple springs are jointly fixedly installed on a force-bearing plate, and two blocks are fixedly installed on the upper surface of the force-bearing plate. The blocks and the stop blocks are located on the same vertical line.

[0012] Furthermore, an adjustment groove is provided on the rear surface of the machine body, and an operating column is fixedly installed on the rear surface of the force plate. The rear end of the operating column extends through to the rear of the machine body and is fixedly installed with a handle.

[0013] Furthermore, a handle is fixedly installed on the upper surface of the cover.

[0014] Beneficial effects: When the device is idle, the rotating column one, gear and rack one meshing transmission can drive the cover to slide along the slide and completely cover the opening of the machine body. At the same time, the gear drives rack two and the blocking block to move synchronously, sealing and blocking the heat dissipation slots on both sides of the machine body. This forms a double dustproof protection structure that closes the opening of the machine body and closes the heat dissipation slots, preventing external dust from entering the inside of the device through gaps or heat dissipation slots. It also prevents dust from adhering to the surface of core electrical components such as the chassis and operating table, effectively reducing problems such as circuit conduction failure and reduced heat dissipation efficiency caused by dust accumulation, and significantly extending the overall service life of the device.

[0015] The machine cover is opened by rotating the second rotating column. After rotation, the machine cover can move backward until the stop block on the lower surface of the machine cover and the stop block on the force plate lock together, thus completing the limiting and fixing of the machine cover in the open state. This structure prevents the machine cover from moving back and forth under the elastic action of the first spring, thereby avoiding the unstable up and down movement of the operating table and ensuring the stability of the equipment during teaching operations. When it is necessary to close the machine cover, the force plate is lifted by the first handle, which can release the stop block and the stop block. At this time, the machine cover is reset under the rebound action of the first spring. Then, the machine cover is closed by pulling the second handle. Finally, rotating the second rotating column locks the machine cover in the closed state. The entire opening and closing operation process is clear and convenient. Attached Figure Description

[0024] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a computer multimedia distance education and training teaching device is provided, including a body 1. Slide grooves 14 are provided on both sides of the interior of the body 1. Sliding blocks 15 are slidably installed inside each of the two slide grooves 14. A cover 2 is fixedly installed on the opposite sides of the two sliding blocks 15. Racks 34 are fixedly installed on both sides of the lower surface of the cover 2. A rotating column 3 is rotatably installed inside the body 1 via a rotating shaft. Two gears 4 are fixedly installed on the outer wall of the rotating column 3. The upper part of the outer wall of the two gears 4 meshes with the lower part of the outer wall of the two racks 34, respectively. A non-standard gear 5 is fixedly installed on the outer wall of the rotating column 3 on the opposite side of the two gears 4. A shaped gear 5 is fixedly installed on the lower surface of the interior of the body 1. There is a threaded rod 6, and a threaded block 7 is threadedly installed on the outer wall of the threaded rod 6. The threaded block 7 is located in front of the special gear 5. An operating table 8 is fixedly installed on the upper surface of the threaded block 7. T-slots 9 are opened on both sides of the inside of the machine body 1 and below the rotating column 3. T-blocks 10 are slidably installed inside the two T-slots 9. Racks 11 are fixedly installed on opposite sides of the two T-blocks 10. The upper part of the outer wall of rack 11 meshes with the lower part of the outer wall of gear 4. A shielding block 12 is fixedly installed on the lower surface of the two racks 11. Through-type heat dissipation slots 13 are opened on both sides of the machine body 1. A chassis 32 is fixedly installed on the lower surface of the inside of the machine body 1. A display screen 33 is provided on the front surface of the machine body 1.

[0027] A handle 2 31 is fixedly installed on the upper surface of the cover 2;

[0028] With the coordinated operation of rotating column 3, gear 4, rack 34, slider 15, and slide groove 14, a linkage opening and closing mechanism between cover 2 and operating table 8 is constructed (cover 2 moves back and forth along slide groove 14 via slider 15 to complete the opening and closing operation of the equipment). Combined with the convenient force application design of handle 31, the opening and closing operation of cover 2 is smooth and effortless. When not in use, cover 2 is completely closed to cover the top of body 1. Operating table 8 is stored inside body 1 with the cooperation of threaded block 7 and threaded rod 6 (operating table 8 rises when cover 2 is opened). At the same time, the rotation of gear 4 can synchronously drive rack 11 and T-block 10 to drive shielding block 12 to shield the heat dissipation slots 13 on both sides of body 1, effectively preventing dust intrusion and significantly improving equipment safety and service life.

[0029] The through-type heat dissipation slots 13 on both sides of the body 1 can quickly dissipate the heat generated by the chassis 32 when the equipment is running, ensuring stable operation of long-term remote teaching and realizing an organic combination of heat dissipation and protection functions.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, a rotating column 16 is mounted on the front surface of the body 1 via a rotating shaft, and a slot 17 is provided on the front surface of the cover 2. The rear end of the rotating column 16 extends into the slot 17 and is fixedly mounted with a locking block 18. A rotating valve 19 is fixedly mounted on the front end of the rotating column 16.

[0031] A guide groove 20 is provided on the rear surface of the cover 2. A guide rod 21 is slidably installed inside the guide groove 20. The rear end of the guide rod 21 is fixedly connected to the rear surface of the body 1. A spring 22 is fixedly installed on the rear surface of the body 1 and the rear surface of the cover 2, located on the outer wall of the guide rod 21.

[0032] Two abutments 23 are fixedly installed on the lower surface of the cover 2 and between the two racks 34;

[0033] An installation plate 24 is fixedly installed on the rear surface of the inner body 1. Multiple springs 25 are fixedly installed on the lower surface of the installation plate 24. A force plate 26 is fixedly installed on the lower end of the multiple springs 25. Two blocks 27 are fixedly installed on the upper surface of the force plate 26. The blocks 27 and the abutment block 23 are located on the same vertical line.

[0034] An adjustment groove 28 is provided on the rear surface of the body 1, and an operating column 29 is fixedly installed on the rear surface of the force plate 26. The rear end of the operating column 29 extends through to the rear of the body 1 and is fixedly installed with a handle 30.

[0035] The front surface of the machine body 1 engages with the cover 2 slot 17 via the rotating column 16 and the locking block 18. Combined with the operation design of the front rotary valve 19, the cover 2 can be quickly positioned and fixed after it is closed, preventing the machine from moving or being accidentally opened, thus ensuring the safety of internal components. To unlock, simply rotate the rotary valve 19 to disengage the locking block 18 from the slot 17. The operation is simple and efficient, and it meets the needs of rapid start and stop in teaching scenarios. The corresponding arrangement of the abutment block 23 on the lower surface of the cover 2 and the stop block 27 inside the body 1 allows the cover 2 to be limited by the contact between the abutment block 23 and the stop block 27 after it is opened, preventing the cover 2 from moving back and forth due to the elasticity of the spring 22, which would cause instability of the operating table 8. When it is necessary to close the cover 2, the force plate 26 can be lifted upward by the handle 30, which can release the stop block 27 and the abutment block 23. At this time, the cover 2 will be reset under the rebound of the spring 22. Then, the cover 2 can be closed by pulling the handle 31. Finally, the closed state of the cover 2 can be locked by rotating the rotating column 16, which improves the flexibility of equipment use.

[0036] The specific operation is as follows: When the machine cover 2 is in the closed state during normal idle time, when it needs to be opened, the locking block 18 disengages from the locking groove 17 when the rotary valve 19 is rotated. The machine cover 2 moves backward under the action of the spring 22, and the stop block 23 engages with the stop block 27. When it needs to be closed, the stop block 27 disengages from the stop block 23 by lifting the handle 30, then pulling the handle 31 forward, and finally rotating the rotary valve 19 to make the locking block 18 engage with the locking groove 17 again.

[0037] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
