Description

Technical Field

[0001] This utility model relates to the field of engineering cost model technology, specifically a multi-degree-of-freedom foldable engineering cost model display platform. Background Technology

[0002] Construction cost models are tools and methods used to calculate and evaluate the cost of construction projects. They cover the entire process from investment estimation and design budget to project settlement and final account, ensuring the economic efficiency and rationality of the project.

[0003] However, in existing technologies, when the display panel is unfolded to the target position, the sliding rod only relies on the end of the rotating groove to limit its sliding range, lacking an additional locking structure. In actual use, the display panel is susceptible to the influence of external collision forces, causing the sliding rod to slide unexpectedly along the rotating groove in the folding direction, which in turn causes problems such as displacement of the folding rod position, change of display panel angle, or even accidental folding, thus affecting the stability and display effect of the display panel. To address these issues, we provide a multi-degree-of-freedom folding engineering cost model display platform. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-degree-of-freedom foldable engineering cost model display platform.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-degree-of-freedom folding engineering cost model display platform, comprising a support frame and display panels. Multiple support frames are provided, and two display panels are provided. The two ends of each display panel are rotatably connected to the tops of the two support frames, and rotating grooves are respectively opened on both sides of the display panels. A folding mechanism is slidably connected inside the rotating grooves. A lifting rod is rotatably connected to the bottom of each support frame, and a threaded block is threadedly connected to the outer wall of the lifting rod. A support block is fixedly connected to one end of the threaded block, and a roller is rotatably connected to the inner side of the support block via a rotating shaft. The corner of the threaded block is slidably connected to the inner wall of the support frame. A servo motor is fixedly connected to the inner wall of the support frame, and the output end of the servo motor is fixedly connected to the top of the lifting rod. A set of symmetrical clamping mechanisms is provided at the bottom of the two display panels.

[0006] The aforementioned folding mechanism includes a limiting rod, a sliding rod, an adjusting rod, and an adjusting block. The two ends of the sliding rod are respectively fixedly connected to one end of the two limiting rods, and one end of the limiting rod is fixedly connected to one end of the adjusting rod. The outer wall of the adjusting rod is threadedly connected to the inside of the adjusting block.

[0007] As mentioned above, the two limiting rods are located on both sides of the rotating groove, and a drive rod is fixedly connected to one end of the adjusting block.

[0008] As described above, the top convex surface of the drive rod is in close contact with the bottom of the display panel, and the outer wall of the slide rod is rotatably connected to a folding rod, with one end of the folding rod rotatably connected to the inside of the support frame.

[0009] The aforementioned clamping mechanism includes a moving block, a push rod, and a spring. One end of the moving block is fixedly connected to one end of the push rod, and the spring is sleeved on the outer wall of the push rod.

[0010] As described above, the bottom end of the movable block is slidably connected to a fixed block one, and one end of the fixed block one is tightly attached to a fixed block two. The top ends of the fixed block one and the fixed block two are respectively fixedly connected to the bottom ends of the two display boards, and one end of the spring is fixedly connected to one end of the fixed block one.

[0011] As described above, the end of the spring away from the fixed block is fixedly connected to the mounting block, and the top end of the mounting block is fixedly connected to the bottom end of the display board. The end of the push rod away from the moving block passes through the mounting block and is fixedly connected to the pull rod.

[0012] Compared with existing technologies, this multi-degree-of-freedom foldable engineering cost model display platform has the following advantages:

[0013] I. This utility model, through its folding mechanism, allows the slide rod to slide within the rotating groove when the display panel is unfolded. The slide rod moves to the end of the rotating groove, simultaneously moving two limiting rods to the same position. Then, the outer limiting rod is pressed against the groove, and the drive rod is rotated. Because the adjusting block inside the drive rod is threadedly connected to the adjusting rod, the convex surface at the top of the drive rod is always in close contact with the bottom of the display panel. At the same time, one side of the drive rod is in close contact with one of the limiting rods. This prevents the slide rod from sliding within the rotating groove, thus limiting the position of the folding rod and effectively preventing accidental sliding of the slide rod due to external force when the display panel is unfolded, ensuring the display panel remains in a stable unfolded state.

[0014] II. This utility model, through its locking mechanism, allows the two display panels to be unfolded. Under the tension of the spring, the spring naturally elongates, pushing the moving block to slide from the bottom of the first fixed block towards the second fixed block. At this time, the moving block tightly abuts against the end face of the second fixed block, locking the first and second fixed blocks together, thus achieving a stable connection between the two display panels. By pulling the lever, the lever drives the push rod to move. At this time, the spring is compressed, and the push rod drives the moving block away from the interior of the first fixed block, thereby releasing the locking state between the first and second fixed blocks. This allows the two display panels to fold into the inner wall of the support frame. Conversely, after being released, the lever automatically resets and completes the locking. No additional tools or complicated steps are required, greatly improving the efficiency of assembling and disassembling the display panels.

[0015] 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 1-5As shown, this utility model provides a technical solution: a multi-degree-of-freedom folding engineering cost model display platform, including a support frame 1 and a display panel 2. Multiple support frames 1 are provided, and two display panels 2 are provided. The two ends of the display panels 2 are rotatably connected to the tops of the two support frames 1 respectively. Rotating grooves 3 are respectively opened on both sides of the display panels 2, and a folding mechanism 4 is slidably connected inside the rotating grooves 3. A lifting rod 5 is rotatably connected to the bottom of the support frame 1, and a threaded block 6 is threadedly connected to the outer wall of the lifting rod 5. A support block 7 is fixedly connected to one end of the threaded block 6, and a roller 9 is rotatably connected to the inner side of the support block 7 via a rotating shaft. The corner of the threaded block 6 is slidably connected to the inner wall of the support frame 1. A servo motor 10 is fixedly connected to the inner wall of the support frame 1, and the output end of the servo motor 10 is fixedly connected to the top of the lifting rod 5. A set of symmetrical clamping mechanisms 8 is provided at the bottom of the two display panels 2.

[0024] First, when display panel 2 is unfolded, the folding mechanism 4 slides within the rotating groove 3, moving to the end of the rotating groove 3. Then, the drive rod 11 is rotated, ensuring the convex surface at the top of the drive rod 11 remains firmly against the bottom of display panel 2. Simultaneously, one side of the drive rod 11 is pressed against one side of one of the folding mechanisms 4, preventing the folding mechanism 4 from sliding within the rotating groove 3. This limits the position of the folding rod 12, effectively preventing accidental sliding of the folding mechanism 4 due to external force when unfolding display panel 2, ensuring the display panel 2 remains in a stable unfolded state. Finally, after both panels are unfolded, the elastic tension of the clamping mechanism 8 causes its natural extension, pushing it along the fixed... The bottom end of fixed block 13 slides towards fixed block 2 14. At this time, the clamping mechanism 8 tightly abuts against the end face of fixed block 2 14, locking fixed block 13 and fixed block 2 14 into one piece, thereby achieving a stable connection between the two display panels 2. By pulling the pull rod 16, the pull rod 16 drives the push rod 802 to move. At this time, the spring 803 is compressed, and then the push rod 802 drives the moving block 801 to leave the interior of fixed block 13, thereby releasing the clamping state between fixed block 13 and fixed block 2 14, so that the two display panels 2 are folded into the inner wall of the support frame 1. Conversely, after being released, the pull rod 16 automatically resets and completes the locking. No additional tools or complicated steps are required, which greatly improves the assembly and disassembly efficiency of the display panels 2.

[0025] like Figure 1-3As shown, the folding mechanism 4 includes a limiting rod 401, a sliding rod 402, an adjusting rod 403, and an adjusting block 404. The two ends of the sliding rod 402 are fixedly connected to one end of each of the two limiting rods 401, and one end of the limiting rod 401 is fixedly connected to one end of the adjusting rod 403. The outer wall of the adjusting rod 403 is threadedly connected to the inside of the adjusting block 404. The two limiting rods 401 are located on both sides of the rotating groove 3. One end of the adjusting block 404 is fixedly connected to a driving rod 11, and the limiting rod 401 near the driving rod 11 is movably connected to the outer wall of the adjusting rod 403. The top convex surface of the driving rod 11 is in close contact with the bottom of the display panel 2. The outer wall of the sliding rod 402 is rotatably connected to a folding rod 12, and one end of the folding rod 12 is rotatably connected to the inside of the support frame 1.

[0026] When the display panel 2 is unfolded, the slide rod 402 slides within the rotating groove 3, moving to the end of the rotating groove 3. Simultaneously, the slide rod 402 drives the two limiting rods 401 to move to the same position. Then, the outer limiting rod 401 is pressed against the screen, and the drive rod 11 is rotated. Since the adjusting block 404 inside the drive rod 11 is threadedly connected to the adjusting rod 403, the convex surface at the top of the drive rod 11 is always in close contact with the bottom of the display panel 2. At the same time, one side of the drive rod 11 is in close contact with one of the limiting rods 401. This prevents the slide rod 402 from sliding within the rotating groove 3, thereby limiting the position of the folding rod 12 and effectively preventing the slide rod 402 from accidentally sliding due to external force when the display panel 2 is unfolded, ensuring that the display panel 2 maintains a stable unfolded state.

[0027] like Figure 1 , Figure 4 and Figure 5 As shown, the clamping mechanism 8 includes a movable block 801, a push rod 802, and a spring 803. One end of the movable block 801 is fixedly connected to one end of the push rod 802, and the spring 803 is sleeved on the outer wall of the push rod 802. The bottom end of the movable block 801 is slidably connected to a fixing block 13, and one end of the fixing block 13 is tightly attached to a fixing block 2 14. The top ends of the fixing blocks 13 and 2 14 are respectively fixedly connected to the bottom ends of the two display panels 2. One end of the spring 803 is fixedly connected to one end of the fixing block 13. The end of the spring 803 away from the fixing block 13 is fixedly connected to a mounting block 15, and the top end of the mounting block 15 is fixedly connected to the bottom end of the display panel 2. The end of the push rod 802 away from the movable block 801 passes through the mounting block 15 and is fixedly connected to a pull rod 16.

[0028] After the two display panels are unfolded, the spring 803 stretches under the tension of the spring, pushing the moving block 801 to slide along the bottom of the fixed block 13 towards the fixed block 2 14. At this time, the moving block 801 tightly abuts against the end face of the fixed block 2 14, locking the fixed block 13 and the fixed block 2 14 into one unit, thus achieving a stable connection between the two display panels 2. By pulling the pull rod 16, the pull rod 16 drives the push rod 802 to move. At this time, the spring 803 is compressed, and the push rod 802 drives the moving block 801 away from the inside of the fixed block 13, thereby releasing the clamping state between the fixed block 13 and the fixed block 2 14, so that the two display panels 2 can be folded into the inner wall of the support frame 1. Conversely, after being released, the pull rod 16 automatically resets and completes the locking. No additional tools or complicated steps are required, which greatly improves the assembly and disassembly efficiency of the display panels 2.

[0029] Working principle: First, when the display panel 2 is unfolded, the slide rod 402 slides within the rotating groove 3, moving to the end of the rotating groove 3. Simultaneously, the slide rod 402 moves the two limiting rods 401 to the same position. Then, the outer limiting rod 401 is pressed against the surface, and the drive rod 11 is rotated. Because the adjusting block 404 inside the drive rod 11 is threadedly connected to the adjusting rod 403, the convex surface at the top of the drive rod 11 remains in close contact with the bottom of the display panel 2. At the same time, one side of the drive rod 11 is in close contact with one of the limiting rods 401, thus preventing the slide rod 402 from sliding within the rotating groove 3, thereby limiting the position of the folding rod 12. Finally, after the two panels are unfolded, the spring 80... The tensile force of 3 causes the spring 803 to naturally elongate, pushing the movable block 801 to slide along the bottom end of the fixed block 13 towards the fixed block 2 14. At this time, the movable block 801 tightly abuts against the end face of the fixed block 2 14, locking the fixed block 13 and the fixed block 2 14 into one unit, thereby achieving a stable connection between the two display panels 2. By pulling the pull rod 16, the pull rod 16 drives the push rod 802 to move. At this time, the spring 803 is compressed, and then the push rod 802 drives the movable block 801 to leave the interior of the fixed block 13, thereby releasing the clamping state between the fixed block 13 and the fixed block 2 14, so that the two display panels 2 are folded into the inner wall of the support frame 1. Conversely, after being released, the pull rod 16 automatically resets to complete the locking.

[0030] 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.
