Description

Technical Field

[0001] This utility model relates to the field of drawing display technology, specifically a modular splicing engineering cost drawing display rack. Background Technology

[0002] Construction cost estimation is a professional activity that involves predicting, calculating, controlling, and managing the costs required throughout the entire process of construction project, from decision-making to completion and delivery. It specifically covers key aspects such as preliminary investment estimation, design stage budget, construction stage budget, and final settlement. It mainly uses pricing bases such as quotas and lists, combined with market prices and actual project conditions, to analyze cost composition and control expenses. The ultimate goal is to ensure the rational use of funds, improve project investment efficiency, and facilitate the efficient progress of the project.

[0003] According to a search, Chinese patent document, publication number CN 211529570 U, relates to a display rack for facilitating the display of engineering cost budget results. The rack includes a support plate, comprising a first partition plate and a second partition plate. The second partition plate is fixedly connected to a base, with an opening at its end furthest from the base. A connecting plate is fixedly connected between the sidewalls of the two first partition plates near the base. Each of the inner sidewalls of the two first partition plates has a sliding groove along its length. Both ends of the display stand slide along the length of the first partition plate and are connected to the two sliding grooves. The first partition plate is inserted into the second partition plate along its opening direction. The second partition plate has a locking element for locking the first partition plate. The inner sidewalls of the second partition plate are also open, with the openings vertically oriented and wider than the thickness of the display stand. Limiting elements restrict the sliding of the display stand are provided on the inner sidewalls of the sliding grooves. This invention is easy to carry.

[0004] Because the display stand in the above-mentioned device lacks a positioning structure for cost drawings, technicians can only rely on thumbtacks to fix the drawings. Repeated punctures by the thumbtacks will leave dense dents on the surface of the drawings and the display stand. Long-term use will easily lead to damage and deformation of the table surface. In addition, the edges of the drawings fixed by the thumbtacks are prone to damage, curling or tearing due to uneven stress, which will affect the integrity of the drawings and subsequent review. In view of this, we provide a modular splicing engineering cost drawing display rack. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a modular splicing engineering cost drawing display rack.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular splicing engineering cost drawing display rack, including a support frame, with multiple limiting frames fixedly connected to one side of the top of the support frame, and sliding guide rails fixedly connected to the corresponding surfaces of the multiple limiting frames. A first limiting magnet is fixedly connected to one end of the sliding guide rail. A display panel is slidably connected to the outer wall of the limiting frame, and multiple sliding grooves are provided at both the upper and lower ends of the display panel. A second limiting magnet is fixedly connected to one end of the sliding groove. Multiple rotating parts are fixedly connected to both sides of the outer wall of the display panel, and a movable part is rotatably connected to one side of the outer wall of the rotating part via a rotating shaft. A first fixing magnet is fixedly connected to one side of the outer wall of the movable part, and multiple second fixing magnets are fixedly connected to both sides of the outer wall of the display panel.

[0007] As described above, the plurality of limiting frames are fixed symmetrically to the top of the outer wall of the support frame.

[0008] As described above, the outer wall of the sliding guide rail passes through one end of the sliding groove, and the outer wall of the sliding guide rail is in close contact with the inner wall of the sliding groove. The outer wall of the sliding guide rail is slidably connected to the inner wall of the sliding groove, and one end of the sliding guide rail abuts against the inner wall of one end of the sliding groove.

[0009] As described above, one side of the outer wall of the first limiting magnet is closely attached to the second limiting magnet, and the first limiting magnet and the second limiting magnet are attracted to each other.

[0010] As mentioned above, the outer wall of the display panel has multiple straight slots, and the multiple straight slots are symmetrically arranged on both sides of the outer wall of the display panel.

[0011] As described above, the second fixed magnet is strip-shaped, embedded inside the display panel, and the outer wall of the second fixed magnet is flush with the outer wall of the display panel.

[0012] As described above, the first fixed magnet rotates with the movable component on one side of the outer wall of the display panel, and the outer wall side of the first fixed magnet and the outer wall side of the second fixed magnet attract each other.

[0013] Compared with existing technologies, this modular splicing engineering cost drawing display rack has the following advantages:

[0014] I. This utility model allows the cost drawings to be laid flat on the outer wall of the display board. Technicians only need to gently rotate the movable part to bring it close to the first fixed magnet. The first and second fixed magnets adhere tightly under the magnetic attraction, firmly pressing the edges of the drawings onto the surface of the display board. This process does not require piercing with thumbtacks, and the display board will not leave dents. It can maintain a flat surface even after long-term use, avoiding the problems of damage and deformation of the drawings and the surface of the display board. At the same time, the magnetic attraction force is more evenly distributed, and the edges of the drawings will no longer curl or tear due to local damage or excessive force. This not only protects the integrity of the drawings, but also makes it convenient to fold or mark them directly for later review.

[0015] II. This utility model allows the display panel to be gently pulled to one side via the straight groove, enabling it to slide smoothly along the outer wall of the sliding guide rail. As the display panel moves, the first and second limiting magnets that were originally attracted gradually detach, allowing the display panel to be removed from the limiting frame. During installation, simply align the sliding groove with the sliding guide rail and gently push the display panel. When it slides to the end, it will automatically adhere and be quickly fixed, achieving a modular splicing effect. This allows technicians to quickly and easily remove the display panel according to actual needs.

[0016] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] like Figure 1-4 As shown, this utility model provides a technical solution: a modular splicing engineering cost drawing display rack, including a support frame 1. Multiple limiting frames 2 are fixedly connected to one side of the top of the support frame 1, and sliding guide rails 201 are fixedly connected to the corresponding surfaces of the multiple limiting frames 2. A first limiting magnet 202 is fixedly connected to one end of the sliding guide rail 201. A display plate 203 is slidably connected to the outer wall of the limiting frame 2, and multiple sliding grooves 204 are opened at both the upper and lower ends of the display plate 203. A second limiting magnet 205 is fixedly connected to one end of the sliding groove 204. Multiple rotating parts 3 are fixedly connected to both sides of the outer wall of the display plate 203, and a movable part 301 is rotatably connected to one side of the outer wall of the rotating part 3 through a rotating shaft. A first fixing magnet 302 is fixedly connected to one side of the outer wall of the movable part 301, and multiple second fixing magnets 303 are fixedly connected to both sides of the outer wall of the display plate 203.

[0024] After laying the cost drawings flat on the outer wall of the display board 203, the technicians only need to turn the movable part 301 slightly to make the movable part 301 and the first fixed magnet 302 close to the display board 203. The first fixed magnet 302 and the second fixed magnet 303 are tightly attached under the action of magnetic attraction, and the edges of the drawings are firmly pressed onto the surface of the display board 203.

[0025] like Figure 1 As shown, multiple limiting frames 2 are fixed symmetrically to the top of the outer wall of the support frame 1.

[0026] By symmetrically fixing multiple limiting frames 2 to the top of the support frame 1, the display panel 203 can be more stably constrained between the multiple limiting frames 2.

[0027] like Figure 1 As shown, the outer wall of the sliding guide rail 201 passes through one end of the sliding groove 204, and the outer wall of the sliding guide rail 201 is in close contact with the inner wall of the sliding groove 204. The outer wall of the sliding guide rail 201 is slidably connected to the inner wall of the sliding groove 204, and one end of the sliding guide rail 201 abuts against the inner wall of one end of the sliding groove 204.

[0028] The sliding guide rail 201 passes through the sliding groove 204 and fits tightly, which can ensure the stability of the display board 203 when sliding. In addition, the sliding guide rail 201 abuts against one end of the sliding groove 204, which can effectively constrain the sliding range of the display board 203 and prevent it from coming out of the limiting frame 2.

[0029] like Figure 1 As shown, one side of the outer wall of the first limiting magnet 202 is closely attached to the second limiting magnet 205, and the first limiting magnet 202 and the second limiting magnet 205 are attracted to each other.

[0030] The first limiting magnet 202 and the second limiting magnet 205 are attracted to each other and can be automatically fixed when the display board 203 slides into place, locking the position of the display board 203 without the need for additional tools.

[0031] like Figure 1 As shown, the outer wall of the display panel 203 has multiple straight slots 206, and the multiple straight slots 206 are symmetrically opened on both sides of the outer wall of the display panel 203.

[0032] The straight slots 206 symmetrically opened on the outer wall of the display panel 203 allow technicians to directly remove the display panel 203 from the support frame 1 using the straight slots 206.

[0033] like Figure 1 As shown, the second fixed magnet 303 is strip-shaped and is embedded inside the display panel 203, with the outer wall of the second fixed magnet 303 flush with the outer wall of the display panel 203.

[0034] The strip-shaped second fixing magnet 303 is embedded in the display panel 203 and flush with the outer wall, which avoids the possible scratches caused by the protrusion of the second fixing magnet 303 and reduces the possibility of damage to the drawings caused by the protruding part.

[0035] like Figure 1 As shown, the first fixed magnet 302 rotates with the movable part 301 on one side of the outer wall of the display panel 203, and the outer wall side of the first fixed magnet 302 and the outer wall side of the second fixed magnet 303 attract each other.

[0036] The first fixed magnet 302 rotates with the movable part 301 and is attracted to the second fixed magnet 303. This avoids the damage to the drawings caused by the use of thumbtacks in traditional devices, making it especially suitable for scenarios where the display content needs to be adjusted frequently, thus greatly improving the efficiency of use.

[0037] Working principle: Multiple limiting frames 2 are symmetrically fixed to the top of the support frame 1, which allows the display panel 203 to be more stably constrained between the multiple limiting frames 2. The sliding guide rail 201 passes through the sliding groove 204 and fits tightly, which can ensure the stability of the display panel 203 when sliding. In addition, the sliding guide rail 201 abuts against one end of the sliding groove 204, which can effectively constrain the sliding range of the display panel 203 and prevent it from falling out of the limiting frame 2. The first limiting magnet 202 and the second limiting magnet 205 are attracted and cooperate, which can automatically fix the display panel 203 when it slides into place, locking the display panel 203 without additional tools. At position 3, symmetrical straight slots 206 are opened on the outer wall of the display panel 203, allowing technicians to directly remove the display panel 203 from the support frame 1 using the straight slots 206. The strip-shaped second fixing magnet 303 is embedded in the display panel 203 and flush with the outer wall, avoiding possible scratches caused by the protrusion of the second fixing magnet 303 and reducing the possibility of damage to the drawings caused by the protrusion. The first fixing magnet 302 rotates with the moving part 301 and is attracted to the second fixing magnet 303, which can avoid the damage to the drawings caused by the traditional device using thumbtacks for fixing. It is especially suitable for scenarios where the display content is frequently adjusted, greatly improving the efficiency of use.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
