Description

Technical Field

[0001] The invention relates to the technical field of engineering cost auditing, and in particular to an engineering cost auditing auxiliary tool. Background Art

[0002] Project cost audit refers to the review and evaluation of the authenticity and legality of the total cost of a construction project. Its main goals include checking the authenticity and legality of the project price settlement and the actual investment amount, as well as whether there are any violations. In the project cost audit, in order to achieve real-time monitoring and feedback of the project cost, help auditors improve work efficiency, ensure the accuracy of the audit, standardize the audit process and reduce the audit cost, the present invention proposes a project cost audit auxiliary tool.

[0003] According to the search, the Chinese patent document, announcement number: CN218826121U, discloses a data inspection auxiliary tool, which places the engineering cost data on the front end of the display board by moving the pressure plate upward, and then when the pressure plate is released, the spring will press the pressure plate to fix the engineering cost data, move the observation rod upward, align the upper edge of the observation rod with the engineering cost data to be viewed, and then compare line by line. When an error is found, place the pen holder above the pen drag, and then slide the guide rail to move left and right, driving the pen to draw lines on the engineering cost data to remind, and watch the engineering cost data line by line through the observation rod, reducing the probability of errors in data inspection and comparison when the staff produces visual fatigue. However, the device can only adjust the angle of the display board during actual use, and cannot adjust its height, so it cannot be applied to different occasions; and the function of the device is relatively single, and it is not convenient to move and adjust, which reduces the overall practicality. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an engineering cost audit auxiliary tool, which has the advantages of convenient movement and position adjustment, diversified functionality, and improved work efficiency, thereby solving the above-mentioned technical problems.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an engineering cost audit auxiliary tool, comprising a base, a driving motor is fixedly installed inside the base, a pillar is fixedly installed on the top surface of the base, a limiting slide groove is provided inside the pillar, a threaded rod and a slider are installed inside the limiting slide groove, a rotating shaft is installed on the inner side of the slider, and a display board is installed on the outer side of the rotating shaft.

[0006] Preferably, the number of the pillar, the limiting slide groove and the sliding block is two, and the two sliding blocks are slidably installed inside the two limiting slide grooves respectively.

[0007] Through the above technical solution, when the two sliders slide inside the two limiting slide grooves respectively, the two sliders can drive the rotating shaft and the display board to move in the vertical direction, so that the height of the display board can be effectively adjusted to adapt to different usage occasions. At the same time, when the display board is rotated, the display board can be rotated on the outer side of the rotating shaft, so the angle of the display board can be effectively adjusted, thereby improving the overall practicality of the device.

[0008] Preferably, the number of the threaded rods is two, and the two sliding blocks are respectively threadedly connected to the outer sides of the two threaded rods.

[0009] Through the above technical solution, when the two threaded rods rotate, the two threaded rods can respectively drive the two sliders to move in the vertical direction, thereby adjusting the height of parts such as display boards. At the same time, the two limiting slide grooves can also effectively limit the positions of the two sliders to prevent them from excessive movement or offset, thereby improving the overall practicality and stability of the device.

[0010] Preferably, synchronous wheels are installed on the outer side surfaces of the two threaded rods, belts are transmission-connected on the outer side surfaces of the two synchronous wheels, and the output shaft of the drive motor is fixedly connected to the bottom end of one of the threaded rods.

[0011] Through the above technical solution, when the drive motor is started, the output shaft of the drive motor can drive one of the threaded rods and the synchronous wheel to rotate, and this synchronous wheel can then drive the other synchronous wheel and the threaded rod to rotate together through the belt, thereby effectively adjusting the height position of parts such as the slider. Therefore, only a single motor is used to drive the device to move, effectively improving the overall transmission performance.

[0012] Preferably, a projection screen and a tool box are installed on the front side of the display board.

[0013] Through the above technical solution, a projector can be used to project image information onto a projection screen, which is convenient for use. The projection screen can be retracted into the shell when not in use, so as not to affect the normal use of the display board, thereby increasing the demand for device diversification. The installed tool box can be used to store writing pens, cleaning agents, magnetic stickers and other items, which is convenient for storing tools. While providing convenience for auditors, it can effectively ensure a clean and tidy working environment.

[0014] Preferably, four casters are installed on the bottom surface of the base.

[0015] Through the above technical solution, the four casters can facilitate the staff to move the device to the required position, reducing the demand for manpower and labor intensity, which is convenient and labor-saving. At the same time, the device can be moved at any time when needed, which can also save space and improve utilization efficiency.

[0016] Compared with the prior art, the present invention provides an auxiliary tool for project cost auditing, which has the following beneficial effects: 1. The present invention starts a driving motor, and the output shaft of the driving motor can drive one of the threaded rods and the synchronous wheel to rotate. The synchronous wheel can drive the other synchronous wheel and the threaded rod to rotate together through a belt. The two threaded rods can respectively drive two sliders to move in the vertical direction. The two sliders can drive the rotating shaft and the display board to move in the vertical direction, so as to effectively adjust the height of the display board to adapt to different usage occasions. At the same time, the two limiting slide grooves can also effectively limit the positions of the two sliders to prevent them from excessive movement or offset, and only a single motor can be used to drive the device to move, effectively improving the overall transmission performance.

[0017] 2. The present invention can rotate the display board on the outer side of the shaft, so that the angle of the display board can be effectively adjusted; the image information is projected onto the projection screen by using a projector, which is convenient for use, and the projection screen can be retracted into the shell when not in use, so as not to affect the normal use of the display board, thereby increasing the demand for device diversification, and the tool box can be installed to store writing pens, cleaning agents, magnetic stickers and other items, which is convenient for storing tools, providing convenience for auditors while effectively ensuring a clean and tidy working environment.
