Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to the field of temporary construction site gate technology, specifically a convenient opening and closing device for a temporary construction site gate. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction. The site where construction work takes place is called the "construction site" or "building site."

[0003] In the construction industry, with the continuous increase in building height and depth, temporary construction site gates are widely used. To facilitate installation and use, they are usually fixed by drilling holes in the ground and installing latches. However, this method results in the gate not being able to be fixed after it is opened, and the latches are prone to friction and damage to the finished road surface during the opening process. When the temporary construction site gate is closed, since it cannot be opened from the outside, people outside the site need to slide the latches upward little by little through the gap at the bottom of the temporary construction site gate to open it, which is time-consuming and extremely inconvenient.

[0004] Therefore, it is desirable to provide a temporary fence gate opening and closing device that allows the temporary fence gate to be opened from both inside and outside the gate, without causing friction or damage to the finished road surface during the opening process, and the temporary fence gate can be fixed after opening, making it convenient and flexible to use.
