Technical Field

[0001] This utility model relates to the field of workbench technology, specifically a workbench for engineering cost calculation. Background Technology

[0002] In the process of engineering cost accounting, in order to avoid accounting errors, the accountants need to check the engineering drawings. The engineering drawings are generally large in size, and the workbenches of the accountants are mostly ordinary desks. When the drawings need to be checked, they are laid flat on the table, which not only restricts the work area, but also makes the drawings prone to wrinkles and folds, resulting in damage. When checking the drawings, the accountants need to keep their heads down. The long hours of accounting work put a heavy burden on the neck of the accountants, which is a certain drawback. Utility Model Content

[0003] The purpose of this utility model is to provide a workbench for engineering cost calculation to solve the above-mentioned technical problems.

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1-7 This utility model provides a technical solution: a workbench for engineering cost calculation, including a tabletop 1 and a table frame 2. A slide rail 4 is horizontally fixed to one side of the table frame 2. Two drawing fixing components 3 are slidably installed on the slide rail 4. The drawing fixing components 3 are composed of a rectangular tube 31, a sliding plate 32, and a slider 33. A U-shaped seat 34 is fixedly installed on the top of the slider 33. The bottom end of the rectangular tube 31 is hinged by a pin 35. The sliding plate 32 is slidably installed inside the rectangular tube 31. A threaded column groove 31b is vertically opened on one side plate of the rectangular tube 31. A threaded column 32c is fixedly connected to one side of the sliding plate 32. The threaded column 32c is slidably installed in the threaded column groove 31b. A threaded positioning sleeve 32b is threadedly sleeved on the threaded column 32c. A rubber anti-slip pad is provided on the side of the threaded positioning sleeve 32b near the rectangular tube 31. The position of the sliding plate 32 is fixed by friction.

[0023] The upper half of one side plate of the rectangular tube 31 is a hollow structure. The lower half of one side of the sliding plate 32 has a positional difference in thickness between the upper half and the lower half of the rectangular tube side plate. One side of the upper half of the sliding plate 32 and the outer wall of the side plate of the rectangular tube 31 with the hollow groove are located on the same vertical plane.

[0024] The inner walls of the parallel side plates of the rectangular tube 31 are fixedly connected with limit strips 31c. The sliding plate 32 has limit grooves 32a on both sides that are adapted to the limit strips 31c. The limit strips 31c are slidably arranged in the limit grooves 32a.

[0025] It also includes a positioning bolt 6. Two through holes are provided at the bottom of one side of the rectangular tube 31. Two through holes are also provided on the side plate of the U-shaped seat 34. One through hole is used for the hinge of the pin 35 and the rectangular tube 31. The other through hole is used for the positioning bolt 6 to fix the rectangular tube 31 on the U-shaped seat 34. The positioning bolt 36 passes through the through hole to fix or lay the rectangular tube 31.

[0026] A scale line 31a is provided on one side of the rectangular tube 31 for precisely adjusting the height of the sliding plate 32.

[0027] Working Principle: When calculating costs, the personnel first adjust the distance between the two drawing fixing components 3 by sliding the slider 33 on the slide rail 4 according to the length of the engineering drawing 5, so that it matches the length of the drawing. After the distance is adjusted appropriately, the drawing 5 is placed face up between the rectangular tube 31 and the sliding plate 32. Then, the magnetic adhesive 6 is used to firmly fix the drawing 5 to the two drawing fixing components 3. At this time, the drawing 5 is facing forward, which makes it easy for the personnel to clearly view the details of the drawing from the front of the workbench and carry out the calculation work efficiently. When the drawing 5 is fixed with its back facing up, the device can be used as a drawing display rack, which is convenient for displaying the contents of the drawing to others. When fixing a larger drawing 5, the sliding plate 32 can be slid upward as needed. The sliding plate 32 slides up and down inside the rectangular tube 31, thereby expanding the height of the drawing fixing components 3 to accommodate the fixing needs of drawings of different sizes. If the accountant does not need to view drawing 5 temporarily, the positioning bolt 36 can be pulled out. Since the rectangular tube 31 is hinged to the U-shaped seat 34 via the pin 35, the rectangular tube 31 can be laid horizontally around the pin 35. At this time, the entire device is no different from an ordinary workbench and can be used as a regular work surface, making it convenient for the accountant to perform other tasks. The entire device is easy to operate and can be flexibly adjusted according to different sized drawings and work scenarios, greatly improving the efficiency and convenience of engineering cost accounting.
