Lock catch apparatus for vehicle glazing

Abstract

The invention relates to an automobile glazed window locking device which comprises an installation seat fixed on a side enclosure, a link rod, an unlocking handle, a glass steady rest fixed to the glass of a window, a first pin, a second pin and a third pin connecting the parts. One end of the link rod is connected with the installation seat through the first pin, and the other end of the link rod is connected with one end of the unlocking handle. The other end of the unlocking handle is connected with the glass steady rest through pins. The invention further comprises a limiting spring which is fixed on the unlocking handle. Both ends of the unlocking handle are arranged on both sides of the connection point of the link rod and the unlocking handle. Elastic locking structures matched with the connection end of the installation holder of the link rod, and the body of the link rod are respectively arranged on the end of the limiting spring close to the glass steady rest and the end ofthe limiting spring close to the installation seat. Compared with prior art, the invention plays a role in limiting the link rod when a lock catch is locked and unlocked through adding the limiting spring fixed to the unlocking handle, thus increasing the unlocking force of the lock catch and the unlocking moment of the lock catch, and preventing the lock catch from being unlocked automatically. The locking device is simple in structure and reliable in use.
