Description

Technical Field

[0001] This utility model belongs to the field of engineering cost technology, and specifically relates to a display rack for engineering cost estimation. Background Technology

[0002] A cost estimate display rack is a physical or digital tool designed to display and manage cost information for engineering projects. These racks are commonly used in construction, infrastructure, and other engineering projects to help project managers, engineers, and clients clearly understand key information such as project budgets, cost analyses, and fund allocations.

[0003] Existing construction cost display racks use magnets to attach material lists or other materials to display panels inside the rack, helping personnel clearly understand the project's cost. However, the display panels are limited in size and cannot be flexibly expanded. For large and complex projects involving a huge amount of cost information (such as extremely long lists, multi-disciplinary comparisons, etc.), the fixed-size panels quickly fill up, leading to the omission of key data or the need for frequent content changes, disrupting the integrity and continuity of the information. Furthermore, cost estimators are handling projects of different sizes simultaneously. A display panel suitable for small projects is insufficient for large projects, while a large fixed panel customized for large projects is cumbersome and wasteful of space for small projects. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing a display rack for engineering cost estimates. When the amount of project information is large or more comprehensive content needs to be displayed, additional panels can be easily unfolded to provide ample display space, ensuring that all key information is clearly visible. Furthermore, it can be quickly folded to significantly reduce its size, making it easy to store and not taking up too much space.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a display rack for engineering cost estimation, including a frame, a display panel is rotatably arranged inside the frame via a rotating column, an extension plate is hinged to the upper and lower sides of the display panel via friction hinges, a dovetail groove is provided on the rear side of the display panel, a plurality of locking plates are slidably arranged inside the dovetail groove, a docking groove is provided at the lower end of the extension plate, the plurality of locking plates are respectively inserted into the adjacent docking groove, an elastic drive mechanism is provided between two locking plates, the elastic drive mechanism includes a sliding cylinder and a sliding column respectively arranged on the inner side of the two locking plates, and the sliding column is slidably connected to the inside of the sliding cylinder, a high carbon steel spring is provided between the two locking plates, and the high carbon steel spring is sleeved on the outer arc surface of the sliding cylinder and the sliding column.

[0006] As a further improvement of this utility model, the lower end of the frame is provided with multiple support frames, and the frame and the support frames are fixed together by welding. Multiple casters are rotatably provided at the lower ends of the multiple support frames.

[0007] As a further improvement of this utility model, several strong magnets are respectively provided on the outer surfaces of the display board and the expansion board. If the strong magnets are distributed at equal intervals, and the strong magnets on the display board and the strong magnets on the expansion board are opposite poles attracting each other, multiple auxiliary plates are provided on the opposite inner surfaces of the expansion board.

[0008] As a further improvement of this utility model, a drive box is provided on the right side of the frame, and a worm gear is rotatably mounted inside the drive box. A worm wheel that meshes with the worm gear is provided at the right end of the rotating column. An auxiliary unit for assisting the rotation of the worm gear is provided at the front end of the worm gear, and the auxiliary unit includes a handwheel located on the front side of the worm gear. The worm gear and the handwheel are fixed together by welding.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, by rotating the handwheel, the display board and extension board on the rotating column can be rotated 90 degrees and laid flat, making it easy for project managers, engineers, and clients to gather around the display board and clearly understand the project budget, which is suitable for cost estimators to discuss cost information.

[0011] Secondly, by simultaneously pinching the two locking plates and pulling the auxiliary plate with the other hand, the extension plates on both sides are rotated via friction hinges to align with the vertical and horizontal alignment of the display plate, and then secured by strong magnets, achieving full and comprehensive fixation of the extension plates. When the project involves a large amount of information or requires displaying more comprehensive content, additional panels can be easily unfolded, providing ample display space and ensuring that all key information is clearly visible. By pinching the locking plates on both sides and then releasing them, the high-carbon steel springs quickly return to their original position, allowing the locking plates to insert into the docking slots and quickly folding and fixing the extension plates. This rapid folding significantly reduces the size, making it easy to store and not taking up too much space.

[0012] Third, the casters allow the entire frame to move in any direction on the horizontal plane and are secured by brakes, greatly enhancing the flexibility and mobility of the equipment. This is especially important for scenarios that require frequent position adjustments or rapid transfer of display racks between different work areas. Attached Figure Description

Detailed Implementation

[0019] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0020] like Figure 1 , 2 As shown, a display rack for engineering cost estimates includes a frame 101. Inside the frame 101, a display panel 104 is rotatably mounted via a rotating column. Extension plates 202 are hinged to the upper and lower sides of the display panel 104 via friction hinges. A dovetail groove 207 is provided on the rear side of the display panel 104. Multiple locking plates 204 are slidably mounted inside the dovetail groove 207. A docking groove 206 is provided at the lower end of the extension plate 202. The multiple locking plates 204 are inserted into adjacent docking grooves 206. An elastic drive mechanism is provided between two locking plates 204. Several strong magnets 201 are provided on the outer surfaces of the display panel 104 and the extension plate 202, and the strong magnets 201 on the display panel 104 and the strong magnets 201 on the extension plate 202 are opposite poles attracting each other. Multiple auxiliary plates 203 are provided on the opposite inner surfaces of the extension plate 202.

[0021] A drive box 301 is provided on the right side of the frame 101. A worm gear 303 is rotatably installed inside the drive box 301. A worm wheel 302 that meshes with the worm gear 303 is provided at the right end of the rotating column. An auxiliary unit for assisting the rotation of the worm gear 303 is provided at the front end of the worm gear 303. The auxiliary unit includes a handwheel 304 provided on the front side of the worm gear 303.

[0022] like Figure 3 , 4 As shown, the elastic drive mechanism includes a slide cylinder 208 and a slide column 209 respectively disposed on the inner sides of the two locking plates 204, and the slide column 209 is slidably connected to the inside of the slide cylinder 208. A high carbon steel spring 205 is disposed between the two locking plates 204, and the high carbon steel spring 205 is sleeved on the outer arc surface of the slide cylinder 208 and the slide column 209.

[0023] Cost estimators can display the project cost by attaching the material list or other materials to the display board 104 inside the display rack using magnets, making it easy for personnel to clearly and comprehensively understand the project cost.

[0024] By rotating the handwheel 304, the worm gear 303 can be rotated, which in turn drives the worm wheel 302 that meshes with it to rotate, causing the display board 104 and the extension board 202 on the rotating column to rotate 90 degrees and lay them flat, so that project managers, engineers and customers can clearly understand the project budget by surrounding the display board 104.

[0025] When there are many cost materials to be displayed, and the space of the display board 104 is full, by simultaneously pinching the two locking plates 204, the two locking plates 204 slide towards each other and leave the interior of the docking groove 206 under the restriction of the dovetail slide groove 207, and the slide column 209 slides inside the slide cylinder 208. Then, the auxiliary plate 203 can be pulled with the other hand to rotate the two side extension plates 202 to correspond vertically and horizontally with the display board 104 through the friction hinge. The friction hinge can use the internal friction to maintain the opening angle. It ensures that the component can stay in a certain position without additional support by precisely controlling the rotational resistance, and is attracted and fixed by the strong magnet 201, so as to fully and completely fix the extension plate 202, thereby making it easy for the cost personnel to stably fix the remaining cost materials to be displayed on the extension plate 202 by magnet.

[0026] After the cost materials are displayed, by pinching the locking plates 204 on both sides, the sliding column 209 slides inside the sliding cylinder 208, and the high carbon steel spring 205 is compressed. Then, the auxiliary plate 203 is pulled to reset the expansion plate 202. Then, the locking plates 204 on both sides are released, and the high carbon steel spring 205 quickly rebounds to reset, so that the locking plates 204 are inserted into the docking groove 206, and the expansion plate 202 is quickly folded and fixed.

[0027] According to another embodiment of the present invention, such as Figure 1As shown, the lower end of the frame 101 is provided with multiple support frames 102, and multiple casters 103 are rotatably provided between the lower ends of the multiple support frames 102. The casters 103 allow the entire frame 101 to move in any direction on the horizontal plane and are fixed by brakes, which greatly enhances the flexibility and mobility of the equipment.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
