The intelligent three-dimensional garage comprises a circular foundation pit formed in the ground, a lifting mechanism arranged at thebottom of the circular foundation pit, a vehicle bearing mechanism arranged on the lifting mechanism, a guide column arranged in the circular foundation pit, an auxiliary lifting mechanism arranged atthe upper end of the guide column, a locking mechanism arranged on the inner wall of the circular foundation pit and matched with the vehicle bearing mechanism, a cleaning mechanism arranged at the bottom of the circular foundation pit for scouring the circular foundation pit, and a control mechanism arranged on the ground for controlling the lifting mechanism, the vehicle bearing mechanism, theauxiliary lifting mechanism, the cleaning mechanism and the locking mechanism. The floor area is small, the quick parking and taking of multiple vehicles can be realized, the quick parking and takingof a single vehicle can be realized, vehicles can be taken directly from an outlet end after the vehicles are parked from an inlet end, the taking efficiency is improved, and the phenomenon of sludgeenrichment at the bottom caused by too deep of the foundation pit is avoided.

Lock bolt for groove
The invention provides a groove anti-loosening bolt, which includes a head and a screw rod. The screw rod has an external thread, and the external thread part is evenly distributed with a number of grooves parallel to the axis of the bolt along the circumference of the bolt. The self-locking nut used for matching at least There is a shut-off that falls into said groove. When the invention is assembled, the contact area between the self-locking nut and the bolt thread is reduced, which can reduce friction, reduce the probability of dry friction, improve the ability of anti-reverse moment, and improve the product life; it has excellent anti-vibration performance and can be used in Guaranteed locking performance under strong vibration environment; can increase assembly speed; provide high, continuous and stable preload and improve fatigue strength; suitable for assembly in places where tools cannot be used.
