Description

Technical Field

[0001] This utility model relates to the field of display board technology, specifically to an engineering cost display board. Background Technology

[0002] Construction cost refers to the activities of forecasting, calculating, controlling, and managing all expenses required for construction projects throughout the entire process from project preparation to completion, acceptance, and handover. It covers the capital consumption and cost management at each stage of construction and is one of the core management contents in the field of construction engineering.

[0003] In existing technologies, different drawings need to be displayed in engineering cost estimation. Display boards are needed to better show the contents of the drawings, making it easier for construction personnel to intuitively view the details of the drawings, clearly conveying engineering information, facilitating observation and discussion by multiple parties, and accurately grasping the key design points. This helps to improve the efficiency of engineering cost communication and the accuracy of solution decision-making.

[0004] However, when presenting drawings, especially large ones, the fixed and non-adjustable display board makes it impossible to lay the drawings flat. The drawings need to be repeatedly folded and disassembled, making it difficult for viewers to form an overall understanding. Because the display board size is fixed, the edge details of the drawings may be outside the visible range, affecting the accuracy of data reading. Therefore, we propose an engineering cost display board. Utility Model Content

A secondary plate is provided at the other end of the double-section arm, and the other end of the double-section arm is rotatably connected to the inner wall of one end of the secondary plate.

[0007] In some embodiments, the auxiliary mechanism includes a baffle, one end of which is provided with a connecting rod. One end of the baffle is rotatably connected to the interior of the connector. The top side of the connecting rod is fixedly connected to the bottom end of the display panel body. After the angle is adjusted, the baffle contacts one side of the sub-panel.

[0008] In some embodiments, the inner wall of the display panel body is provided with a linear groove, the inner surface of the linear groove is provided with a protrusion, the inner surface of the linear groove is slidably connected to the outer side of the protrusion, one end of the protrusion is provided with a locking rod, and one end of the protrusion is fixedly connected to the bottom end of the locking rod.

[0009] In some embodiments, the middle end of the locking rod is rotatably connected to the inner side of the display panel body, and an elastic rope is provided on the inner wall of the display panel body, with one end of the elastic rope being fixedly connected to the inner wall of the display panel body.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please refer to Figure 1 - Figure 7This utility model provides a technical solution: an engineering cost display board, including an adjustment mechanism 1, an auxiliary mechanism 2 at the bottom of the adjustment mechanism 1, the adjustment mechanism 1 including a display board body 11, a crossbar 12 on one side of the display board body 11, one side of the display board body 11 being fixedly connected to one end of the crossbar 12, a vertical plate 13 on the outer side of the crossbar 12, the outer side of the crossbar 12 being slidably connected to the inner wall of the vertical plate 13, a double-section arm 14 on the inner wall of the middle end of the vertical plate 13, the inner wall of the middle end of the vertical plate 13 being rotatably connected to one end of the double-section arm 14, a secondary plate 15 on the other end of the double-section arm 14, the other end of the double-section arm 14 being rotatably connected to the inner wall of one end of the secondary plate 15, a linear groove 110 on the inner wall of the display board body 11, a protrusion 19 on the inner surface of the linear groove 110, the inner surface of the linear groove 110 being slidably connected to the outer side of the protrusion 19, and one end of the protrusion 19 being... The device has a locking rod 16, one end of which is fixedly connected to the bottom end of the locking rod 16. The middle end of the locking rod 16 is rotatably connected to one side of the interior of the display panel body 11. An elastic rope 18 is provided on the inner wall of the display panel body 11. One end of the elastic rope 18 is fixedly connected to the inner wall of the display panel body 11. The side of the elastic rope 18 away from the inner wall of the display panel body 11 is fixedly connected to the side of the protrusion 19. A side plate 17 is provided on one side of the locking rod 16. One side of the locking rod 16 slides in contact with one side of the side plate 17. A fixing handle 111 is provided at the middle end of the side plate 17. One end of the fixing handle 111 is fixedly connected to the middle end of the side plate 17. The outer side of the fixing handle 111 slides in contact with the inner wall of the display panel body 11. A limiting plate 112 is provided on one side of the display panel body 11. One end of the limiting plate 112 is rotatably connected to the side of the display panel body 11. The inner side of one end of the limiting plate 112 is rotatably engaged with the outer side of the fixing handle 111.

[0028] When using this type of engineering cost display board, firstly, a horizontal bar 12 is installed on one side of the display board body 11. The horizontal bar 12 has two vertical plates 13 slidably connected to its outer side. A double-section arm 14 is installed at the middle of the vertical plate 13. The other end of the double-section arm 14 is installed on the inner wall of one end of the sub-plate 15 and is connected by rotation. Then, by pulling the sub-plate 15, the vertical plate 13 slides on the horizontal bar 12 until the sub-plate 15 is pulled to the end of the horizontal bar 12. At this time, the sub-plate 15 will be completely exposed from the rear side of the display board body 11. After being exposed, the sub-plate 15 can be moved forward a short distance under the action of the double-section arm 14 so that it is on a parallel line with the display board body 11, thereby increasing the usable area of ​​the display board body 11 and meeting the need for a larger display space when displaying engineering costs.

[0029] A linear groove 110 is formed on the inner wall of the display panel body 11. The linear groove 110 is arc-shaped and has a protrusion 19. One end of the protrusion 19 is fixed to the bottom end of the locking rod 16. The locking rod 16 is L-shaped and can be rotated 90 degrees through the linear groove 110. When the locking rod 16 is rotated, the side plate 17 designed on one side of the locking rod 16 pushes the side plate 17 to one side, causing the locking rod 16 to change angle under the action of external force, so that the final angle of the locking rod 16 is 90 degrees. During this process, one end of the locking rod 16 will enter the sub-plate 15 to limit and fix the sub-plate 15, preventing displacement due to external force and ensuring the stability of the complete display plane formed by the sub-plate 15 and the display panel body 11.

[0030] After the side panel 17 slides to a certain position, a limiting plate 112 is designed on one side of the display panel body 11. When moving the side panel 17, it is necessary to hold the fixing handle 111 to move the side panel 17. After moving, the fixing handle 111 will come to the side of the limiting plate 112. At this time, by rotating the limiting plate 112, it will lock the fixing handle 111, thereby fixing the fixing handle 111 and keeping the side panel 17 stationary after moving, ensuring that the connection between the locking rod 16 and the sub-plate 15 will not be broken.

[0031] An elastic rope 18 is designed on one side of the protrusion 19, and the other end of the elastic rope 18 is fixed in the linear groove 110. In this way, when the locking rod 16 is unrestricted, the protrusion 19 can be pulled back by the action of the elastic rope 18, and the locking rod 16 can be reset at the same time. The sub-plate 15 is no longer controlled, and the sub-plate 15 can then be reset.

[0032] Example 2: Please refer to Figure 1 The auxiliary mechanism 2 includes a baffle 21, one end of which is provided with a connecting rod. One end of the baffle 21 is rotatably connected to the inside of the connector 22. The top side of the connecting rod is fixedly connected to the bottom end of the display panel body 11. After the angle is adjusted, the baffle 21 contacts one side of the sub-plate 15.

[0033] A connector 22 is designed on the bottom side of the display panel, and a baffle 21 is designed on the inner side of the connector 22. Therefore, by turning the baffle 21 ninety degrees, since the baffle 21 is L-shaped, when the sub-plate 15 moves a short distance, the baffle 21 can restrict the sub-plate 15 to avoid excessive movement due to improper control. The movement distance of the sub-plate 15 can be precisely controlled to ensure that the locking rod 16 can be accurately embedded into the sub-plate 15 to lock it after it reaches the predetermined position. This avoids the locking rod 16 from being misaligned with the locking structure due to excessive movement of the sub-plate 15, and ensures the effectiveness of the limiting and fixing of the sub-plate 15.

[0034] Please see Figure 1- Figure 7 By pulling the sub-plate 15, the vertical plate 13 slides on the horizontal bar 12 until the sub-plate 15 is pulled to the end of the horizontal bar 12. At this point, the sub-plate 15 will be fully exposed from the rear side of the display panel body 11. After exposure, the sub-plate 15 can be moved forward a short distance by the action of the double-section arm 14, so that it is on a parallel line with the display panel body 11. Then, by pushing the side plate 17 to one side, the locking rod 16 changes angle under the action of external force, so that the final angle of the locking rod 16 is ninety degrees. During this process, the locking rod 1... One end of 6 will enter the sub-plate 15 to limit and fix the sub-plate 15 to prevent displacement due to external force. Secondly, when moving the side plate 17, the fixing handle 111 needs to be held to move the side plate 17. After moving, the fixing handle 111 will come to the side of the limiting plate 112. At this time, by rotating the limiting plate 112, it will lock the fixing handle 111, thereby fixing the fixing handle 111 and keeping the side plate 17 in the position after moving, ensuring that the connection between the locking rod 16 and the sub-plate 15 will not be broken.

[0035] By turning the baffle 21 ninety degrees, since the baffle 21 is L-shaped, when the sub-plate 15 moves a short distance, the baffle 21 can restrict the sub-plate 15 to avoid excessive movement due to improper control. By controlling the movement distance of the sub-plate 15, the locking rod 16 can be accurately embedded into the sub-plate 15 to achieve locking after reaching the predetermined position.
