Description

Technical Field

[0001] This utility model relates to the field of vehicle tire installation and removal technology, and in particular to a quick-locking nut for a tire balancer and tire changer. Background Technology

[0002] With the development of automation, tire changing is becoming increasingly automated, and large disc-less workbenches are becoming more common. This is because it facilitates automatic tire removal via tire hooks. However, globally, most tire securing still relies on manual locking. This method is heavy, slow, and tiring for workers. Manufacturers are concerned about quick-locking mechanisms not securing properly, hence the primary reason for manual locking. The same applies to tire balancing machines. Although quick-lock nuts exist, large tires are still manually locked, again due to concerns about quick-locking mechanisms not securing properly. Furthermore, the locking nuts used in tire changing and balancing machines vary widely and are not interchangeable, often made of plastic with generally lower quality. For example, published patent 2024115287510 discloses a tire changing machine that uses a clamping arm to abut against the tire tread to maintain tire stability. However, the clamping arm is inconvenient for quick installation and removal. Using a standard nut and screw mechanism for tire locking still requires unscrewing the nut, resulting in low efficiency. Therefore, it is particularly important to solve the problem that the use of ordinary nuts to lock tires on current tire balancers and tire changers cannot be quickly removed and installed, which affects work efficiency. Utility Model Content
