This utility model belongs to the field of locking connection technology, specifically relating to a barbell / dumbbell quick locking device, including an inner cylinder with an axial through hole and an outer sleeve sleeved outside the inner cylinder. The outer wall of the inner cylinder has a first conical surface, and the inner wall of the outer sleeve is provided with a second conical surface matching the first conical surface. An inclined surface is provided on the outer wall of the inner cylinder on the larger diameter side of the first conical surface. An unlocking button for driving the inclined surface to move axially is provided on the top transverse groove of the outer sleeve. Steel balls are fitted in the first through holes circumferentially spaced on the first conical surface of the inner cylinder. An annular cover plate is connected to the end face of the outer sleeve on the groove side. A spring for driving the inner cylinder to move away from the cover plate is provided between the cover plate and the inner cylinder. The advantages are: simple structure, convenient use, stable performance, reliable locking, and suitable for locking and positioning components on shafts or pipes.

This application relates to a wireless lock system, including a wireless lock, a communication module, a relay module, and a control module. The communication module is communicatively connected to the wireless lock and the relay module. The relay module receives commands from the control module and transmits them to the wireless lock via the communication module. The control module is communicatively connected to the relay module and outputs control commands, including unlocking and closing the wireless lock. This system can efficiently manage multiple wireless locks, achieving remote control, status monitoring, and orderly communication under low power consumption conditions, significantly improving the reliability and applicability of the wireless lock system.
