[0032] This utility model provides a signal detection training platform for electronic information teaching. To make the objectives, technical solutions, and advantages of this utility model clearer and more explicit, the following detailed description, with reference to the accompanying drawings and embodiments, further illustrates the utility model. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this utility model.

[0033] Please also refer to Figures 1 to 6 This utility model provides a signal detection training platform for electronic information teaching, including a training platform cabinet 1, training equipment, and a lifting assembly; the training platform cabinet 1 has a window opening assembly on its surface, the training equipment and the lifting assembly are located inside the training platform cabinet 1, and the lifting assembly connects the training equipment and the window opening assembly; when the lifting assembly controls the training equipment to rise, it opens the window opening assembly to allow the training equipment to extend from the surface of the training platform cabinet 1; when the lifting assembly controls the training equipment to descend into the training platform cabinet 1, it closes the window opening assembly.

[0034] When needed, the training equipment can be extended onto the table for normal operation; when not in use, the training equipment can be stored inside the training table cabinet 1, and the window opening component can be closed to prevent dust from entering the training table cabinet 1, which greatly reduces the accumulation of dust and the frequency of cleaning, saves manpower and time, and helps to extend the service life of the training equipment.

[0035] In this embodiment, the training platform cabinet 1 has a through-hole 2 on its surface. The window opening assembly includes a first sliding plate 3 and a second sliding plate 4, which are installed side-by-side in the slot 2. The adjacent sides of the first sliding plate 3 and the second sliding plate 4 are aligned and abut against each other. The bottom surfaces of the first sliding plate 3 and the second sliding plate 4 are fixedly connected to a lifting assembly. The lifting assembly controls the first sliding plate 3 and the second sliding plate 4 to slide together or separate within the slot. The first sliding plate 3 has a first strip-shaped through hole 5 with one end open, and the second sliding plate 4 has a second strip-shaped through hole 6 with one end open. When the first sliding plate 3 and the second sliding plate 4 are brought together, the openings of the first strip-shaped through hole 5 and the second strip-shaped through hole 6 are joined and connected. When the first sliding plate 3 and the second sliding plate 4 are separated, the training equipment extends from the first strip-shaped through hole 5, the second strip-shaped through hole 6, and the openings where the two sliding plates are separated. The size of the two strip-shaped through holes matches the display screen, allowing the display screen to rise smoothly.

[0036] In this embodiment, the training equipment includes a display screen 7 and an operation panel 8. The display screen 7 is located inside the training platform cabinet 1 and away from the cabinet door 9, while the operation panel 8 is located in the middle of the training platform cabinet 1. Both the display screen 7 and the operation panel 8 are connected to a lifting assembly. Since the display screen 7 is higher than the operation panel 8, as... Figure 6 As shown, when the lifting assembly controls the separation of the first sliding plate 3 and the second sliding plate 4, the display screen 7 rises before the operation plate 8, gradually rising from the first strip-shaped through hole 5 and the second strip-shaped through hole 6; as the opening where the first sliding plate 3 and the second sliding plate 4 separate gradually becomes larger, the operation plate 8 extends out from the opening onto the table surface.

[0037] like Figure 2 As shown (with one cabinet door removed to facilitate the display of the internal storage panels), preferably, the two cabinet doors 9 on the front of the training table cabinet 1 are hinged to both ends of the front. Several storage panels 10 are mounted on the side adjacent to the cabinet doors 9 for placing relevant training tools, materials, etc. A leg 11 is provided at each of the four corners of the bottom surface of the training table cabinet 1, and anti-slip pads 32 can be fixedly installed at the bottom of the leg 11 to enhance the stability of the cabinet.

[0038] like Figure 3 (The cabinet doors and display panels have been removed to better showcase the specific structure of the lifting components.) Figure 4 and Figure 5(The training platform cabinet 1 has been removed, and the structure of the lifting assembly and training equipment is shown from another direction.) As shown, the lifting assembly includes a telescopic cylinder 12, a lifting frame, an equipment rack for mounting the display screen 7, a first slide rod, and a second slide rod. A square groove is provided on the bottom plate of the training platform cabinet 1. The telescopic cylinder 12 is fixed in the square groove and connected to an external controller. The lifting frame is fixed on the piston at the top of the telescopic cylinder 12. The operating plate 8 is fixed on the top of the lifting frame. The equipment rack is fixed on the inner side of the lifting frame and connected to the lifting frame. The first slide rod and the second slide rod are located on both sides of the lifting frame, and the inner sides of the two slide rods rotate and abut against the lifting frame. The bottoms of the first slide rod and the second slide rod are fixed on the bottom plate. The top of the first slide rod is fixed on the bottom of the first sliding plate 3, and the top of the second slide rod is fixed on the bottom of the second sliding plate 4.

[0039] The telescopic cylinder 12 is controlled by an external controller to raise and lower its piston. A simplified electric cylinder controller from the LECP1 series is preferred, requiring no programming and allowing for setup via panel buttons and knobs, making operation simple and convenient. The connection between the telescopic cylinder and the controller is existing technology, such as a direct wired connection. This involves directly connecting the controller's output port to the telescopic cylinder's motor or electromagnetic coil via a multi-core cable, which will not be detailed here.

[0040] When the piston of the telescopic cylinder 12 rises, it drives the lifting frame to rise, which in turn drives the equipment frame to rise. The rising equipment frame causes the display screen 7 to extend from the first strip-shaped through hole 5 and the second strip-shaped through hole 6. At the same time, the rising of the lifting frame controls the first sliding rod and the second sliding rod to separate outward. The first sliding rod drives the first sliding plate 3 to slide outward, and the second sliding rod drives the second sliding plate 4 to slide outward, so that the first sliding plate 3 and the second sliding plate 4 can separate and gradually increase the distance between them. When the lifting frame rises to the preset height limit position, it stops rising. At this time, the operating plate 8 extends out from the opening where the two sliding plates are separated.

[0041] When the telescopic cylinder 12 descends, it drives the lifting frame to descend, which in turn drives the equipment frame to descend, causing the display screen 7 to gradually descend into the training platform cabinet 1. Simultaneously, the descent of the lifting frame drives the operating panel 8 to descend, controlling the first and second sliding rods to converge inwards. The first sliding rod drives the first sliding plate 3 to slide inwards, and the second sliding rod drives the second sliding plate 4 to slide inwards, allowing the first and second sliding plates 3 and 4 to gradually approach each other. When the lifting frame descends to a preset low position, the first and second sliding plates 3 and 4 converge and join together.

[0042] Preferably, the lifting frame includes a base frame 13, a first connecting arm 14, a second connecting arm 15, and a lifting plate 16; the upper end of the first connecting arm 14 is fixed to one side of the base frame 13 (to...). Figure 2Taking the direction shown as an example (left side), the lower end of the first connecting arm 14 is provided with a first connecting frame 17, the outer side of the first connecting frame 17 is slotted and a first rotating roller 18 is provided at the slot opening; during lifting and lowering, the first rotating roller 18 rotates up and down along the inner side of the first slide rod; the upper end of the second connecting arm 15 is fixed to the other side of the base frame 13 (taking the direction shown as left side as right side as left side as left side as left side as left side as left side as left side as left side as left side of the left side of the right side of the ... Figure 2 Taking the direction shown as an example (right side), the lower end of the second connecting arm 15 is provided with a second connecting frame. The outer side of the second connecting frame is slotted and a second rotating roller is provided at the slot opening. During lifting, the second rotating roller rotates up and down along the inner side of the second slide rod. One end of the lifting plate 16 is fixed between the top of the telescopic cylinder 12 and the bottom surface of the base frame 13, and the other end of the lifting plate 16 is connected to the equipment frame.

[0043] The first connecting arm 14 and the second connecting arm 15 have the same structure, with the upper end higher and the lower end lower, forming an inclined shape. The lifting plate 16 is bent into a stepped shape, with the upper stepped surface used to fix it to the base frame 13, and the lower stepped surface used to fix the equipment frame.

[0044] The equipment rack includes four uprights 30 and a mounting plate 31. Two uprights are arranged at intervals on both sides of the training platform cabinet 1. The mounting plate 31 is positioned between the four uprights. The bottom surface of the mounting plate 31 is fixed to the lifting plate 16, and the display screen 7 is mounted on the top surface of the mounting plate 31. This positioning ensures that when the lifting plate 16 moves the mounting plate 31 up and down along the uprights, the mounting plate 31 will not deviate or tilt due to the obstruction of the uprights, making the movement path more stable and preventing the display screen 7 from shaking.

[0045] The first sliding rod includes a first fixed base 19, a first storage tube 20, and a first telescopic rod 21. The bottom of the first storage tube 20 is rotatably connected to the first fixed base 19. A cylindrical first storage cavity is opened inside the first storage tube 20. A first top spring 22 is provided in the first storage cavity. The bottom end of the first top spring 22 is fixed to the bottom of the first storage cavity. The top end of the first top spring 22 is fixedly connected to the bottom of the first telescopic rod 21. The top end of the first telescopic rod 21 is fixed to the bottom surface of the first sliding plate 3 by a first fixing member 23.

[0046] The axial connection means that the bottom of the first storage tube 20 is fixed to the first fixed base 19 and can rotate. Specifically, the first fixed base 19 includes two oppositely arranged feet 24 and a horizontal shaft. A circular groove is provided in the middle of the two feet 24. A through hole is opened at the bottom of the first storage tube 20. After the horizontal shaft passes through the through hole, its two ends are respectively inserted into the corresponding grooves for locking. The dimensions of the through hole, the horizontal shaft, and the grooves are preferably such that the first storage tube 20 can rotate around the horizontal shaft without falling off the feet. The bottom of the first storage tube 20 is arc-shaped to facilitate its rotation.

[0047] When the telescopic cylinder 12 is in its lowest position, the first rotating roller 18 abuts against the lower end of the first receiving tube 20, and the first receiving tube 20 is tilted at this time. As the piston of the telescopic cylinder 12 extends, the first rotating roller 18 rotates and moves from bottom to top along the inner side of the first receiving tube 20, which is equivalent to providing a thrust to the first receiving tube 20 to gradually make it vertical. Due to the limitation of the first sliding plate 3, the first telescopic rod 21 presses down on the first top spring 22, so that the lower end of the first telescopic rod 21 gradually extends into the first receiving cavity. The first receiving tube 20 and the first telescopic rod 21 gradually become vertical, which is equivalent to moving outward. The first fixing member 23 drives the first sliding plate 3 to slide outward.

[0048] When the telescopic cylinder 12 retracts, the first rotating roller 18 rotates and moves from top to bottom along the inner side of the first receiving tube 20, which is equivalent to the thrust moving from top to bottom. The first receiving tube 20 gradually tilts, and the first telescopic rod 21 is pushed out by the first top spring 22, so that the lower end of the first telescopic rod 21 gradually extends out of the first receiving cavity. The first receiving tube 20 and the first telescopic rod 21 gradually tilt, which is equivalent to moving inward. The first fixing member 23 drives the first sliding plate 3 to slide inward.

[0049] The structure and working principle of the second slide rod are the same as those of the first slide rod, the difference being the connecting components. Specifically, the second slide rod includes a second fixed base 25, a second storage tube 26, and a second telescopic rod 27; the bottom of the second storage tube 26 is rotatably connected to the second fixed base 25, and a cylindrical second storage cavity is opened inside the second storage tube 26. A second top spring 28 is provided in the second storage cavity. The bottom end of the second top spring 28 is fixed to the bottom of the second storage cavity, and the top end of the second top spring 28 is fixedly connected to the bottom of the second telescopic rod 27. The top end of the second telescopic rod 27 is fixed to the bottom surface of the second sliding plate 4 by a second fixing member 29.

[0050] Please continue reading. Figures 3 to 6 The working principle of the signal detection training platform is as follows:

[0051] When the display screen 7 and the operation panel 8 need to be extended, the piston of the telescopic cylinder 12 is extended by the controller. The telescopic cylinder drives the base frame 13 to rise, and the base frame 13 drives the first connecting arm 14, the second connecting arm 15, the operation panel 8, and the lifting plate 16 to rise. When the two connecting arms rise, the corresponding rotating rollers move from bottom to top along the inner side of the corresponding storage tubes. The bottom of the storage tubes rotates around the horizontal axis, so that the two storage tubes gradually come to a vertical position. The fixing parts on the telescopic rod drive the corresponding sliding plates to slide outward along the slots, so that the two sliding plates separate from each other. When the lifting plate 16 rises, it drives the mounting plate 31 to rise, thereby driving the display screen 7 to rise. The display screen 7 extends out from the first strip-shaped through hole 5 and the second strip-shaped through hole 6, and the operation panel 8 extends out from the opening where the two sliding plates separate. The display screen 7, being higher, will extend first. After the operation panel 8 is lifted, it will be at the same height as the display screen for easy operation. The rising stops when the preset height limit is reached. At this time, the display screen 7 and the operation panel 8 are removed from the training table cabinet 1, and operation can begin.

[0052] When not in use, the piston of the telescopic cylinder 12 is retracted by the controller, causing the base frame 13 to descend. The base frame 13 then causes the first connecting arm 14, the second connecting arm 15, the operating plate 8, and the lifting plate 16 to descend. When the two connecting arms descend, the corresponding rotating rollers move from top to bottom along the inner side of the corresponding storage tubes. The bottom of the storage tubes rotates in the opposite direction around the horizontal axis (opposite to the direction of rotation during ascent), causing the tops of the two storage tubes to approach each other. The fixing piece at the top of the telescopic rod causes the corresponding sliding plate to slide along the slot 5, bringing the two sliding plates closer together. As the lifting plate 16 descends, the operating plate 8 descends from the opening where the two sliding plates are separated. The mounting plate 19 moves downward, causing the display screen 7 to descend from the first strip-shaped through hole 5 and the second strip-shaped through hole 6. When it descends to the preset low position, the first sliding plate 3 and the second sliding plate 4 come together, and the display screen 7 and the operating plate 8 are hidden inside the training table cabinet 1, achieving a relatively closed structure.

[0053] In summary, the signal detection training platform for electronic information teaching of this utility model raises the display screen and control panel from the training platform cabinet during use via a lifting component, and lowers the display screen and control panel into the interior of the training platform cabinet when not in use. By shortening the time that the display screen and control panel are in direct contact with the outside, dust accumulation and cleaning frequency are reduced, saving manpower and time, and extending the service life of the equipment.

[0054] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
