AI Technical Summary

Technical Problem

The existing portable cost calculation board is small in size and has a single function. It can only be explained verbally during calculation, which reduces the calculation and display effect of construction project cost data, and requires additional support components for support, which is inconvenient to carry.

Method used

A calculation box including a writing board, handle, electronic board and adjustment mechanism is designed. The electronic board is lifted and lowered by the adjustment mechanism, and combined with the writing board for data writing and demonstration. The lower end of the electronic board is equipped with an interface end and electrically connected to the display host, which can perform electronic demonstration and video display.

Benefits of technology

It improves the calculation and display effect of construction project cost data, so that the data can be displayed to others more easily. At the same time, through automated electrical connection and lifting mechanisms, the use and carrying of calculation boxes are simplified.

Abstract

The invention discloses a portable construction engineering cost calculation board which structurally comprises a calculation box composed of a writing board, handles, an electronic board and an adjusting mechanism, the writing board is embedded in the front surface of the calculation box, and the two handles are connected to the top of the calculation box in a closed mode through a mutual lock catch arranged between the two handles. The motor is started to drive the worm to rotate, the rotating worm drives the sliding block to ascend and descend, at the moment, the lifting supporting plate ascends and descends in the calculation box along with the sliding block, and the electronic plate is driven to extend out of the calculation box; the electronic board carries out electronic demonstration on the construction engineering cost data and displays the construction engineering video specifically corresponding to the cost, and the writing board is combined to write the calculation data, so that the effect of calculating the construction engineering cost data and displaying the construction engineering cost data to other people for watching can be improved.
