Description
Technical Field
[0001] This utility model relates to the field of building surveying equipment technology, and in particular to an auxiliary line-laying device for construction projects. Background Technology
[0002] In construction projects, auxiliary line-laying devices often need to work in conjunction with the level body and its support to ensure measurement accuracy and operational stability. Traditional fixing methods typically involve bolts penetrating directly through the top of the support and the bottom of the level body, with the connection achieved through threaded fastening.
[0003] However, when moving and transferring the level to a new location, the level body and the bracket need to be separated for transport. The bolts are threaded on the bracket and can easily loosen due to vibration and collision during the movement, or even fall off completely from the top of the bracket, resulting in the loss of bolt parts. This affects the subsequent rapid reassembly and use of the level body and the bracket. Therefore, how to lock the level body and the bracket through an integrated locking structure to avoid the problem of bolts easily falling off the bracket during transportation has become a key technical requirement for improving the practicality of auxiliary line-laying devices in construction projects. Summary of the Invention
[0004] The purpose of this utility model is to provide an auxiliary line-laying device for construction projects to solve the problems mentioned in the background art.
