Spherical door lock is a kind of practical lock with strong windproof, anti-insertion and anti-theft functions. It has a generous appearance and various styles. Most of the handle shapes are spherical, and there are handles with other shapes. The installation of spherical door locks is extremely simple. Two mounting holes can be opened on the door, one is the tongue of the lock, and the other is the hole of the lock. Generally, the lock can be installed and fixed with two fixing screws. The general structure of the spherical door lock on the market is: the handle and the retaining ring are forged, and the overall accessories are assembled together by means of two bracket tube accessories. Among them, the outer handle is generally screwed directly on the supporting accessories. The problem is that the outer handle makes the mountain loose easily after a while, which will seriously affect the opening of the lock. For the fixing of the safety button, the safety button is generally fixed on a plastic part or other parts that are easily deformed during assembly, and it is directly stuck in another accessory to realize the assembly of the safety button. However, the safety button is fixed on a plastic part or other poorly rigid accessories. Although it is easy to install and can fix the safety button, it will inevitably be deformed in the transmission, especially if it is used with certain force. The locking function of the accessory is directly driven by a single accessory through the connecting rod. The locking structure is too simple to match, which causes the stability of the accessory's movement to be more ordinary in use. If the length is longer, some problems will occur in the transmission, such as: rotation When the friction occurs, the clearance becomes larger, the safety button will shake, and even the transmission will fail. In addition, the inner and outer handle rotation limit structures usually use pins. Pin materials are mostly zinc alloy. After a certain period of time, they are easy to fall and cannot be used.
