Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-3, an anti-collision test structure for buildings comprises a box body 1 and a box cover 10, wherein a handle 14 is connected to the middle of the upper end of the box cover 10, so that the device can be conveniently lifted, and the anti-collision test structure is more practical.
Through holes 15 are symmetrically formed in two sides of the upper end of the box cover 10, T-shaped screws 16 are movably inserted into the through holes 15, threaded holes 17 matched with the T-shaped screws 16 are formed in two sides of the upper end of the box body 1 respectively, after the box cover 10 is covered, the box cover 10 can be fixed by screwing the T-shaped screws 16 into the threaded holes 17, then the T-shaped screws 16 are rotated to be separated from the threaded holes 17, the box cover 10 can be fixed, and therefore the box cover 10 is convenient to open and close.
