Description

Technical Field

[0001] The utility model relates to the technical field of drawing tables, in particular to a multifunctional drawing table for project cost. Background Technique

[0002] Project cost refers to the general term for activities such as budgeting, estimating, accounting, analyzing, and controlling various expenses during the construction process of engineering projects, and is an important link in engineering project management. Accurate project cost management can ensure that the project is efficiently completed within the budget, avoiding unnecessary expenses and waste.

[0003] Despite the rapid development of information technology and computer-aided drawing having become the main tool for engineering design, manual drawing, as one of the basic skills of designers, still occupies an important position in engineering design. Manual drawing not only helps designers more intuitively understand and express design concepts but also provides a more flexible operation method in certain specific scenarios.

[0004] As a drawing tool, a drawing table provides a stable and comfortable operating platform for drafters to post drawing paper and complete hand-drawing operations. After completing the drawing work, traditional drawing tables cannot directly display the drawing results, making it difficult to quickly present the design scheme to team members for discussion. This limitation leads to a lack of immediate communication and feedback during the design process, making it impossible to quickly share opinions or conduct in-depth analysis and discussion. It delays the decision-making process and affects work efficiency and project progress. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that the traditional drawing table lacks a display function, which limits team communication and feedback and affects work efficiency.

[0006] To solve the above technical problem, the technical solution adopted by the utility model is: a multifunctional drawing table for project cost, including a table body. The top of the table body is rotatably connected with a lifting plate through two first hinge seats. One end of the lifting plate is rotatably connected with two limiting sleeves through two second hinge seats. Limiting rods are slidably connected inside both of the two limiting sleeves. A fixing component is arranged on one side of the limiting sleeve. Two clamping grooves for clamping the two limiting rods are opened at the top of the table body. Two rotating rod components are rotatably connected to the top of the lifting plate. The rotating rod components are fixedly connected with a fixing plate through bolts and nuts.

[0007] As a further improvement of the utility model, a slider is fixedly connected to one side of the limiting rod, and a sliding groove for sliding connection of the slider is opened on the inner wall of the limiting sleeve.

[0008] As a further improvement of the present utility model, the fixing assembly includes a fixing cylinder communicating with the limiting sleeve. A fixing column passing through the limiting sleeve is arranged in the fixing cylinder. One side of the fixing column is fixedly connected with a spring, and the other end of the spring is fixedly connected with the limiting sleeve. A plurality of fixing holes for the fixing column to penetrate and fix are formed in the limiting rod.

[0009] As a further improvement of the present utility model, bumps are fixedly connected to one ends of the two limiting rods, and a plurality of grooves for the bumps to be clamped are formed in both of the two clamping grooves.

[0010] As a further improvement of the present utility model, the rotating rod assembly includes a rotating shaft and a rotating handle. A threaded hole for the bolt to be threadedly connected is formed through the rotating handle.

[0011] As a further improvement of the present utility model, a positioning groove for the rotating handle to be clamped is formed in the fixing plate. Through grooves for the two rotating handles to pass through are formed on both sides of the fixing plate, and the positioning groove and the through groove are vertically arranged.

[0012] The beneficial effects of the present utility model: By arranging a lifting plate, a first hinge seat and a second hinge seat at the top of the table body, the angle of the lifting plate can be flexibly adjusted and changed, enabling the user to easily adjust the inclination of the lifting plate according to actual needs. This facilitates the display and discussion of the drawing content, helps the communication and analysis among team members, enhances the interactivity, and thus improves the overall work efficiency. In addition, the design of the limiting rod and the limiting sleeve provides an accurate angle adjustment function, ensuring that the lifting plate remains stable and accurate when adjusting the angle.

[0013] The provided fixing assembly, fixing plate and multiple bumps further enhance the stability during the drawing display. The fixing assembly and the multiple bumps at the bottom end of the limiting rod can ensure that the lifting plate can be firmly held in place at any angle. The fixing plate clamps the drawing to prevent it from sliding or shifting. Description of the Drawings

Therefore, it is possible to change accordingly according to its different positions and different usage states; so, these or other orientation terms should not be interpreted as restrictive terms.

[0022] In this specification, the singular forms "a", "the" and "said" are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application clearer, the following further details this application in combination with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are only used to explain this application and are not used to limit this application.

[0024] The present utility model provides as shown in the attached Figures 1-6 figure, a multi-functional drawing table for project cost, including a table body 1. The top of the table body 1 is rotatably connected with a lifting plate 3 through two first hinge seats 2. One end of the lifting plate 3 is rotatably connected with two limiting sleeves 5 through two second hinge seats 4. Two limiting rods 6 are slidably connected inside the two limiting sleeves 5. A fixing component 7 is arranged on one side of the limiting sleeve 5. Two card slots 8 for the two limiting rods 6 to be clamped are opened at the top of the table body 1. Two rotating rod components 9 are rotatably connected to the top of the lifting plate 3. The rotating rod component 9 is fixedly connected with a fixing plate 12 through a bolt 10 and a nut 11.

[0025] Such as Figure 3As shown, a slider 16 is fixedly connected to one side of the limit rod 6, and a chute for the slider 16 to slide is provided on the inner wall of the limit sleeve 5. The provided slider 16 and chute are beneficial for adjusting the length of the limit rod 6 to meet actual requirements and change the inclination angle.

[0026] As Figure 3 , 4 shown, the fixing component 7 includes a fixing cylinder 701 communicating with the limit sleeve 5. A fixing column 702 passing through the limit sleeve 5 is provided in the fixing cylinder 701. A spring 703 is fixedly connected to one side of the fixing column 702, and the other end of the spring 703 is fixedly connected to the limit sleeve 5. The limit rod 6 is provided with a plurality of fixing holes 704 for the fixing column 702 to penetrate and fix. The provided fixing component 7 provides a stable fixing effect between the limit rod 6 and the limit sleeve 5. One end of two limit rods 6 is fixedly connected with a convex block 13, and a plurality of grooves for the convex block 13 to be clamped are provided in both card slots 8. The convex block 13 and the groove are convenient for reliably fixing the limit rod 6.

[0027] As Figure 5 , 6 shown, the rotating rod component 9 includes a rotating shaft 901 and a rotating handle 902. A threaded hole 903 for the bolt 10 to be threadedly connected is provided through the rotating handle 902. A positioning groove 14 for the rotating handle to be clamped is provided in the fixing plate 12. Through grooves 15 for two rotating handles 902 to pass through are provided on both sides of the fixing plate 12. The positioning groove 14 and the through groove 15 are vertically arranged, and the fixing plate 12 is made of an elastic material. The provided rotating rod component 9 can reliably fix the fixing plate 12 at the positioning groove 14 through the bolt 10 and the nut 11, effectively preventing the drawing from slipping. After releasing the fastening effect of the bolt 10 and the nut 11, by rotating the rotating rod component 9 and passing the rotating handle 902 through the through groove 15, the limiting effect between the rotating rod component 9 and the fixing plate 12 can be released.

[0028] Working principle: When the present utility model is specifically implemented, first, when drawing, the drawing paper is placed on the lifting plate 3, and the fixing plate 12 is pressed against the top of the drawing paper. The rotating shaft 901 is rotated so that the rotating handle 902 passes through the through groove 15 of the fixing plate 12. The rotating shaft 901 is rotated again so that the rotating handle 902 is clamped with the fixing plate 12 made of elastic material through the positioning groove 14. The screw hole 903 fixes the fixing plate 12 through the bolt 10 and the nut 11 in sequence. After the drawing is completed, the first hinge seat 2 is rotated upward to lift the lifting plate 3, and the second hinge seat 4 is rotated to rotate the limit sleeve 5 outward. Then, the fixing column 702 is pulled to deform the spring 703, the limit rod 6 is pulled out, and the movement stops when it reaches an appropriate distance. The convex block 13 at the bottom end of the limit rod 6 is fixed in the corresponding groove inside the clamping groove 8, and the fixing column 702 is released to enable the spring 703 to recover, and the fixing column 702 passes through the corresponding fixing hole 704 for fixing. At this time, the lifting plate 3 is in a stable state. At the same time, the drawing paper on the lifting plate 3, due to the adjustment by the limit rod 6, is at an appropriate inclination angle, which is convenient for the user and team members to communicate and analyze.
