Description

Technical Field

[0001] The present invention relates to the technical field of computer professional training, and more specifically to a training device for computer professional teaching. Background Art

[0002] The teaching content of computer majors covers multiple core fields and courses, mainly including programming languages, algorithms and data structures, operating systems, database systems, network technologies, software engineering, etc.; So when conducting computer teaching training, trainees need to be equipped with relevant training devices (computers), so that through the control of the tutor terminal and the cooperation of specific professional programs, trainees can learn and train related content of the computer, improving the trainees' mastery and understanding of computer professional knowledge; In summary, the present inventor found that the existing training devices mainly have the following defects: Since the display screens of the current training devices are the same as those of conventional computer display screens, when used vertically, they are only positioned by a single base. Therefore, when the keyboard is frequently tapped, it will shake, resulting in an unstable phenomenon. Moreover, when the screen shakes, it is very easy to cause dizziness in some trainees and the phenomenon of collapse and fall due to external impacts. Therefore, it is easy to cause damage to the display screen and reduce the positioning strength of the display screen; At the same time, multiple lines are required to connect the display screen and the host. After the lines are connected, all the lines will come into contact and intertwine with each other. Therefore, when some lines are damaged later, they need to be searched for one by one, reflecting the cumbersome nature and inefficiency of replacing the lines later. Summary of the Invention

[0003] The technical solution adopted by the present invention to achieve the technical purpose is: A training device for computer professional teaching, the structure of which includes: a bearing structure, a host, a control keyboard, a display screen, and a fixator.

[0009] As a further improvement of the present invention, a plastic plate is carried on the surface of the plate body, and the number of slots is the same as the shape and number of the restraint bodies. Both the first circuit groove and the second circuit groove are circular in shape, and the number of the second circuit grooves is greater than the number of the first circuit grooves.

[0010] As a further improvement of the present invention, the restraint body is provided with a splicing block. A conducting wire is connected to the center of the lower end of the splicing block, and a connection end is also arranged at the bottom of the conducting wire to complete the electrical connection with the host computer. Limiting blocks are also fixed on both the left and right sides of the splicing block. A vertical groove is formed by the distance between the limiting blocks on both the left and right sides of the splicing block, and the vertical groove communicates with the contact wall. A thermostatic body is also connected to the back of the splicing block. The thermostatic body is embedded in the splicing block and contacts the inner wall of the contact wall. The temperature of the display screen is balanced through the contact wall, and the conducting wire and the connection end are controlled by the host computer and the control keyboard.

[0011] As a further improvement of the present invention, the splicing block and the limiting blocks form a "concave" shape, and the contact wall is in a finely polished form and coincides with the constant temperature area of the thermostatic body.

[0012] As a further improvement of the present invention, a combination piece is provided at the bottom of the splicing block, one end of which is connected to the block and is perpendicular to the block.

[0015] As a further improvement of the present invention, the shape of the slide groove matches the shape of the bottom of the main machine, and the bottom plate and the straight rod are perpendicular to each other. Two sets of anti-deflection blocks and push blocks are arranged on the straight rod, and the outer layer of the push block is covered by a rubber sleeve.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is based on installing a fixer on the bearing structure. The control keyboard position can be fixed by the front positioning groove of the insulating connecting plate of the fixer to prevent large deviation when tapping. Then, the restraining bodies on the left and right sides can cover and fix the edge of the display screen through the vertical groove. At the same time, the adsorption block in the center of the insulating connecting plate can force the entire display screen to stand upright at the origin, avoiding the occurrence of shaking and instability. Therefore, the origin positioning firmness of the overall training device can be effectively improved.

[0019] 2. The present invention is further improved by the insulating connecting plate. The position of the restraining body can be determined by the slot on the plate body. Then, the opening positions of the line slot 1 and the line slot 2 can be used to effectively distinguish the lines on the control keyboard and the display screen, thereby improving the connection accuracy with the host and preventing the interweaving and entanglement after the connection, ensuring the convenience of distinguishing and replacing the single line in the future.

Furthermore, the constant temperature body can be controlled by the host and the control keyboard through the conductive wire. Therefore, through the cooperation of the constant temperature body and the contact wall, the temperature of the display screen can be balanced, preventing the overheating situation caused by the inability to dissipate the temperature generated after reinforcement.

[0021] 4. After the component on the right side at the lower end of the bearing structure of the present invention is further improved, the host can be embedded through the chute on the bottom plate, so that the side of the host can contact the edge of the straight rod. Subsequently, the anti-deviation block on the straight rod can allow the push block to penetrate, so that the push block can be linearly embedded in the side of the host, improving the effect of fixing the host on the bearing structure and avoiding the displacement caused by accidental contact of the feet. Then, the upper end of the straight rod can improve the connection convenience with the parallel plate of the bearing structure through the magnetic attraction block and the locking bolt, facilitating the subsequent disassembly, installation and displacement effects.

Detailed Implementation Manner

[0030] The present invention will be further described below in conjunction with the accompanying drawings: Embodiment

[0031] Figures 1 to 5 As shown: The present invention provides a training device for computer professional teaching, whose structure includes a bearing structure 1, a mainframe 2, a control keyboard 3, a display screen 4, and a fixer 5. The lower side of the bearing structure 1 fixes the mainframe 2, and the upper surface installs the control keyboard 3 and the display screen 4 through the fixer 5. The display screen 4 and the control keyboard 3 are electrically connected to the mainframe 2 through circuits.

[0032] Among them, the fixer 5 is provided with a convex block 51, an insulating connecting plate 52, a positioning groove 53, a restraint body 54, and a vertical groove 55. The convex block 51 is integrated on the left and right sides of the lower layer of the insulating connecting plate 52, and a positioning groove 53 is also opened on the side to position the control keyboard 3. The restraint body 54 carries the vertical groove 55 and is distributed on the left and right sides of the surface of the insulating connecting plate 52, and clamps both sides of the display screen 4 through the vertical groove 55.

[0033] Among them, the insulating connecting plate 52 is provided with a plate body 521, a slot 522, an adsorption block 523, a circuit groove one 524, and a circuit groove two 525. Slots 522 are opened on the left and right sides of the plate body 521 for the restraint body 54 to be inserted, and the adsorption block 523 is positioned at the center of the surface of the plate body 521 and coincides with the lower end of the display screen 4. The circuit groove one 524 is arranged at the lower part of the adsorption block 523, and the circuit groove two 525 is arranged in the upper area of the adsorption block 523. Both the circuit groove one 524 and the circuit groove two 525 penetrate the plate body 521.

[0034] Among them, the insulating connecting plate 52 of the fixer 5 is installed on the surface of the bearing structure 1 by using the convex block 51, and then the position of the control keyboard 3 is determined by combining the positioning groove 53. At the same time, the vertical restraint bodies 54 on both sides cover and clamp the edge of the display screen 4 in combination with the vertical groove 55. Furthermore, the adsorption block 523 at the center of the surface of the insulating connecting plate 52 adsorbs and fixes the lower end of the display screen 4. At the same time, the circuit groove one 524 on the plate body 521 allows the circuit of the control keyboard 3 to penetrate, and the circuit groove two 525 allows the circuit of the display screen 4 to be separated and penetrate and connect.

[0035] Among them, the bearing structure 1 is composed of support columns and parallel plates and forms a "concave" shape. There are multiple energized data lines connecting the main unit 2 with the control keyboard 3 and the display screen 4. The fixator 5 clamps both left and right sides of the display screen 4 and limits one end of the control keyboard 3.

[0036] Among them, the bump 51 is provided with one piece on each of the lower sides of both sides of the insulating connection plate 52 and is set in a symmetrical orientation. The length of the positioning groove 53 is the same as the length of the control keyboard 3. Both the restraint body 54 and the vertical groove 55 are set in a vertical orientation.

[0037] Among them, the surface of the plate body 521 carries a plastic plate and the number of the slots 522 is the same as the shape and number of the restraint body 54. Both the wire groove one 524 and the wire groove two 525 are circular in shape and the number of the wire groove two 525 is greater than the number of the wire groove one 524.

[0038] Among them, the restraint body 54 is provided with a splicing block 543. The center of the lower end of the splicing block 543 is connected with a conducting wire 542 and a connection end 541 is also arranged at the bottom of the conducting wire 542 to complete the electrical connection with the main unit 2. Limiting blocks 544 are also fixed on both the left and right sides of the splicing block 543. The vertical groove 55 is formed by the distance between the limiting blocks 544 on both the left and right sides of the splicing block 543 and the vertical groove 55 communicates with the contact wall 546. A thermostat 545 is also connected to the back of the splicing block 543. The thermostat 545 is embedded in the splicing block 543 and is in contact with the inner wall of the contact wall 546. The temperature of the display screen 4 is balanced through the contact wall 546 and the conducting wire 542 and the connection end 541 are controlled by the electricity of the main unit 2 and the control keyboard 3.

[0039] Among them, the splicing block 543 and the limiting blocks 544 together form a "concave" shape and the contact wall 546 is in a finely polished form and coincides with the constant temperature area of the thermostat 545.

[0040] Among them, a combination part 5431 is also arranged at the bottom of the splicing block 543. One end of the combination part 5431 is connected with a block body 5432 and is perpendicular to the block body 5432. A threaded ring 5433 is also arranged at the center of the surface of the block body 5432. The connection with the top of the conducting wire 542 is completed through the threaded ring 5433.

[0041] Among them, the combination part 5431 positions the thermostat 545 and the threaded ring 5433 of the block body 5432 is made of plastic. The inner wall is provided with internal threads to firmly connect with the conducting wire 542.

[0042] The specific functions and operation procedures of this embodiment: In the present invention, the training device for computer major teaching can determine the position of the host 2 through the lower side of the bearing structure 1, and at the same time determine the positions of the control keyboard 3 and the display screen 4 on the upper surface. So when the display screen 4 is installed, the fixator 5 covers the surface of the bearing structure 1, enabling the display screen 4 to be perpendicular to the fixator 5. For this purpose, the insulating connecting plate 52 of the fixator 5 can be connected to the parallel plate of the bearing structure 1 through the bump 51. Then, after the positioning groove 53 of the insulating connecting plate 52 determines the position of the restraint body 54, the restraint body 54 can vertically insert the edge of the display screen 4 through the vertical groove 55. Thus, the display screen 4 will be vertically reinforced. Subsequently, the bottom of the display screen 4 will contact the center of the surface layer of the insulating connecting plate 52, enabling the plate body 521 of the insulating connecting plate 52 to secondarily restrain the bottom of the display screen 4 through the adsorption block 523, achieving the effect of secondary reinforcement. Therefore, it can effectively improve the origin positioning strength of the display screen 4, preventing the shaking caused by continuous keyboard tapping or the damage of dropping due to external force. Then, the wire groove 1 524 and the wire groove 2 525 on the plate body 521 are both circular and match the shapes of the relevant energized circuits. For this reason, the wires of the control keyboard 3 can be inserted through the wire groove 1 524, enabling them to be separated from the wires on the display screen 4, avoiding subsequent entanglement. At the same time, the wires carried on the display screen 4 can be inserted through the wire groove 2 525 and extended to the host 2 area. Therefore, the cooperation of the wire groove 1 524 and the wire groove 2 525 can avoid the mutual interweaving of the wires, improving the subsequent efficiency of distinguishing and replacing single wires. Subsequently, the splicing block 543 of the restraint body 54 can form the vertical groove 55 through the limit block 544. So after the display screen 4 enters and coincides with the contact wall 546 through the vertical groove 55, the contact wall 546 balances the temperature of the display screen 4 through the thermostat 545, preventing the situation of unvented temperature and high temperature caused by the edge reinforcement coverage. Furthermore, the thermostat 545 can be connected to the host 2 through the conductive wire 542 and the connection end 541 at the bottom, enabling the temperature of the thermostat 545 to be directly regulated through the control keyboard 3 and the display screen 4, ensuring that the temperature of the display screen 4 can be maintained at a constant temperature state and preventing damage caused by high temperature. Furthermore, the side of the block body 5432 of the splicing block 543 can fix the thermostat 545 through the assembly 5431, enabling the thermostat 545 to be stably installed on the splicing block 543 and then embedded in the block body 5432 in a parallel orientation and coincide with the contact wall 546 to complete the constant temperature control of the display screen 4. Subsequently, the threaded ring 5433 at the bottom center is threadedly connected to the top of the conductive wire 542, replacing the original simple insertion connection, preventing the gradual detachment caused by continuous hanging state and continuous influence of vibration force and centrifugal force, and improving the power-on stability between components. Embodiment

[0043] Figures 6 to 7 As shown: The present invention provides a training device for computer major teaching, Its structure includes that the support column connecting the bearing structure 1 and the host 2 is further provided with a sliding groove 11. The sliding groove 11 is opened at the left surface layer of the bottom plate 12, and a straight rod 13 is welded at the center of the bottom plate 12. A deviation prevention block 14 is fixed on the side of the straight rod 13 and penetrated by a push block 15. The push block 15 penetrates through the side of the straight rod 13 through the deviation prevention block 14 and is connected to the side of the host 2.

[0044] Among them, the shape of the sliding groove 11 matches the shape of the bottom of the host 2, and the bottom plate 12 is perpendicular to the straight rod 13. Two groups of deviation prevention blocks 14 and push blocks 15 are arranged on the straight rod 13, and the outer layer of the push block 15 is covered by a rubber sleeve.

[0045] Among them, a rod body 131 is further provided on the upper half of the straight rod 13. A magnetic attraction block 132 is fixed at the top of the rod body 131, and a connecting sleeve 133 is fixed through the magnetic attraction block 132. A locking bolt 134 penetrates through the center area of the connecting sleeve 133.

[0046] Among them, the top of the rod body 131 is covered by the magnetic attraction block 132, and the connecting sleeve 133 is vertically penetrated and positioned in the side area of the rod body 131 and the magnetic attraction block 132.

[0047] Specific functions and operation procedures of this embodiment: In the present invention, after the support column in the connection area between the lower end of the bearing structure 1 and the host 2 is further improved, the bottom of the host 2 can be embedded by using the sliding groove 11 of the bottom plate 12, so that the host 2 is set in a vertical orientation. Then, the side of the host 2 will contact the side of the straight rod 13. Therefore, the two groups of deviation prevention blocks 14 carried on the other side of the straight rod 13 can allow the push block 15 to penetrate, so that the insulating sleeve carried on the surface of the push block 15 can penetrate through the straight rod 13 together and be embedded in the side part of the host 2 for restraint, ensuring the origin fixity of the host 2 and preventing the continuous displacement caused by simple placement. It ensures the connection stability between the host 2 and the display screen 4 and the control keyboard 3. Subsequently, the rod body 131 on the upper half of the straight rod 13 can coincide with the bottom layer of the parallel plate of the bearing structure 1 through the magnetic attraction block 132 at the top. According to the magnetic attraction effect, a parallel installation state can be achieved. Furthermore, the connection firmness between the parallel plate and the support column can be improved by using the connecting sleeve 133 and the locking bolt 134, and the effect of convenient disassembly and assembly can be achieved, avoiding the difficulty in handling caused by large-scale movement in the later stage due to the integrated structure. The displacement convenience and lightness effect in the later stage can be improved through the detachable effect.

[0048] Using the technical solution of the present invention, or those skilled in the art inspired by the technical solution of the present invention to design a similar technical solution and achieving the above technical effects shall fall within the protection scope of the present invention.
