Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a suspended support for explaining engineering cost drawings. Background Technology

[0002] In the teaching of engineering cost or in the explanation of actual projects, the presentation and explanation of drawings is an indispensable and important part. By presenting design drawings in a clear and intuitive way, students or project participants can not only accurately understand the engineering content, structural details and cost composition, but also improve communication efficiency and decision-making quality.

[0003] Traditional engineering cost drawing presentation stands often use desktop stands, wall-mounted frames, or wall-mounted devices to display drawings. However, these methods generally have problems such as large space occupation, poor flexibility, non-adjustable height, and inconvenient installation. They are difficult to adapt to different venues and presentation needs. In addition, they are greatly affected by light, and the drawings are prone to reflections and shadows, making some content difficult to read and affecting the presentation effect.

[0004] Therefore, it is necessary to design a suspended support for explaining engineering cost drawings to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of traditional engineering cost drawing explanation stands, such as poor flexibility, non-adjustable height, poor adaptability, and susceptibility to light, the technical problem of this utility model is to provide a suspended engineering cost drawing explanation stand.

[0006] This utility model provides a suspended engineering cost drawing explanation bracket, including a fixed plate, a snap-fit ​​block, a motor, a screw, a connecting block, a guide rod, an adsorption plate, an air pump, and a scanning mechanism. The fixed plate has a rectangular array of multiple limiting grooves on its rear side, with snap-fit ​​blocks slidably engaging between these grooves. A motor is fixedly connected to the front side of the fixed plate, and a screw is fixedly connected to the motor's output shaft. A connecting block is threaded onto the screw. Guide rods are symmetrically fixedly connected to the front side of the fixed plate, with two guide rods located on either side of the screw. Both guide rods are slidably connected to the connecting block. An adsorption plate is fixedly connected to the front side of the connecting block, with multiple adsorption holes on its front side. An air pump is connected and communicated with the left side of the adsorption plate, and a scanning mechanism is located on the front side of the adsorption plate.

[0007] In a preferred embodiment of the present invention, the scanning mechanism includes a positioning rod, a baffle, a torsion spring, and a scanner. The positioning rod is fixedly connected to the top of the adsorption plate, and the baffle is rotatably connected to the middle of the positioning rod. Torsion springs are symmetrically connected between the adsorption plate and the baffle, and two torsion springs are respectively wound around the two sides of the positioning rod. The scanner is fixedly connected to the top of the inner wall of the baffle.

[0008] In a preferred embodiment of this utility model, it further includes an infrared sensor, a control screen, and a projector. An infrared sensor is fixedly connected to the front side of the baffle, a control screen is fixedly connected to the right side of the adsorption plate, and a projector is rotatably connected to the bottom of the adsorption plate. The motor, air pump, scanner, infrared sensor, and projector are all electrically connected to the control screen.

[0009] In a preferred embodiment of the present invention, the device further includes a cylinder and a sliding block. The cylinder is fixedly connected to the bottom of the adsorption plate. A sliding groove is provided on the rear side of the projector. The sliding block is slidably connected to the sliding groove. The sliding block is rotatably connected to the piston rod of the cylinder. The cylinder is electrically connected to the control panel.

[0010] In a preferred embodiment of this utility model, a handle is provided on the front side of the baffle.

[0011] In a preferred embodiment of this utility model, the baffle is made of transparent glass.

[0012] Beneficial effects: 1. This utility model can achieve stable hanging through the snap-fit ​​installation method, which is suitable for various teaching or engineering site environments. It greatly improves the convenience and flexibility of explaining engineering cost drawings. The adsorption plate combined with the air pump forms a negative pressure adsorption structure, which can fix drawings of different sizes and avoid the drawings from shifting or wrinkling due to external factors during the explanation, ensuring a clear and stable display effect.

[0013] 2. This utility model uses a scanner and projector to quickly convert paper drawings into digital signals and project them in high definition, breaking through the limitations of traditional explanation methods and enhancing the interactivity and efficiency of teaching or meetings. The infrared sensor and motor linkage structure automatically raises the projection height when a person is detected approaching, effectively preventing the projected image from being blocked and ensuring the continuity of the explanation process and the integrity of the viewing experience.

[0014] 3. This utility model can flexibly adjust the angle of the projector by means of a cylinder drive, adapting to different spatial layouts and projection distance requirements, further optimizing the screen width and clarity, and improving the environmental adaptability of the device.

[0020] Example: A suspended support for explaining engineering cost drawings, such as... Figures 1-4 As shown, the device includes a fixed plate 1, a snap-fit ​​block 3, a motor 4, a screw 6, a connecting block 5, a guide rod 7, an adsorption plate 8, an air pump 9, and a scanning mechanism. The fixed plate 1 has four limiting slots 2 arranged in a rectangular array on its rear side. The snap-fit ​​block 3 is slidably snapped between the four limiting slots 2. The motor 4 is installed on the upper front side of the fixed plate 1 by screws. The output shaft of the motor 4 is connected to the screw 6 by a coupling. The connecting block 5 is threadedly connected to the screw 6. The guide rods 7 are symmetrically welded on the left and right sides of the front side of the fixed plate 1. The two guide rods 7 are located on the left and right sides of the screw 6, respectively. Both guide rods 7 are slidably connected to the connecting block 5. The adsorption plate 8 is welded to the front side of the connecting block 5. The adsorption plate 8 has multiple adsorption holes 10 on its front side. The air pump 9 is connected and communicated to the middle left side of the adsorption plate 8. The scanning mechanism is located on the front side of the adsorption plate 8.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, the scanning mechanism includes a positioning rod 11, a baffle 12, a torsion spring 13, and a scanner 14. The positioning rod 11 is welded to the top of the adsorption plate 8, and the baffle 12 is rotatably connected to the middle of the positioning rod 11. A handle is provided on the front side of the baffle 12. The baffle 12 is made of transparent glass, which has the characteristics of transparency, easy cleaning, and safety, making it easy to directly check whether the engineering cost drawings inside the device are placed correctly. The adsorption plate 8 and the baffle 12 are symmetrically connected by torsion springs 13 on the left and right sides. The two torsion springs 13 are respectively wrapped around the two sides of the positioning rod 11. The scanner 14 is installed on the top of the inner wall of the baffle 12 by screws.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes an infrared sensor 15, a control panel 16, and a projector 17. The infrared sensor 15 is installed on the bottom front side of the baffle 12 by screws. The control panel 16 is installed on the right side of the adsorption plate 8 by screws. The projector 17 is rotatably connected to the bottom left side of the adsorption plate 8. The motor 4, air pump 9, scanner 14, infrared sensor 15, and projector 17 are all electrically connected to the control panel 16.

[0023] When using this device to explain engineering cost drawings, the operator first installs and fixes the snap-fit ​​block 3 to the wall. Then, the entire device is placed from top to bottom, ensuring that the snap-fit ​​block 3 accurately snaps into the limiting groove 2, achieving stable suspension of the device. Next, the handle is pulled upwards to open the baffle 12, exposing the adsorption plate 8 area. The air pump 9 is started via the control panel 16, which extracts air from inside the adsorption plate 8, creating a negative pressure environment. The engineering cost drawings are then placed flat on the adsorption plate 8, and the adsorption holes 10 firmly adhere the drawings, ensuring they do not shift or fall off during the explanation. After placement, the handle is pulled down to close the baffle 12, providing protection and fixation. The operator then... The operator starts the scanner 14 and projector 17 via the control panel 16. The scanner 14 performs a high-definition scan of the drawings on the adsorption plate 8 and transmits the scanned image data to the projector 17. The projector 17 then projects the drawing content clearly onto the wall or other projection surface, facilitating simultaneous viewing and explanation by multiple people. In addition, the device is equipped with an infrared sensor 15. When it detects someone approaching, the sensor transmits a signal to the control panel 16, and the control system then starts the motor 4. The output shaft of the motor 4 drives the screw 6 to rotate, thereby driving the connecting block 5 and the adsorption plate 8 to move upward along the guide rod 7, avoiding the height of the human body and ensuring that the projected image is not disturbed, thus guaranteeing the continuity and clarity of the explanation process.

[0024] like Figure 4 As shown, it also includes a cylinder 18 and a sliding block 20. The cylinder 18 is installed on the bottom right side of the adsorption plate 8 by screws. A slide groove 19 is provided on the rear right side of the projector 17. The sliding block 20 is slidably connected to the slide groove 19. The sliding block 20 is rotatably connected to the piston rod of the cylinder 18. The cylinder 18 is electrically connected to the control panel 16.

[0025] When the image projected by the projector 17 is too narrow or the position is unsuitable, the operator can activate the cylinder 18 through the control panel 16. The piston rod of the cylinder 18 pushes the sliding block 20 forward, allowing it to slide smoothly within the limiting groove 2. At the same time, it drives the projector 17 to rotate around the rotation axis of the adsorption plate 8, adjusting its projection angle. This optimizes the width and position of the projected image until the image content is clear, appropriate, and the coverage area meets the explanation requirements.
