A door lock system comprising a first rotary configured to control extension and retraction of the deadbolt via a primary cam mechanism; a second rotary control configured to control extension and retraction of the latch; and a link configured to retract the deadbolt in response to operation of the second rotary control when the latch is retracted by the second rotary control. The link is configured to move along a linear path normal to the movement of the deadbolt and the door latch and to contact the primary cam mechanism upon the link movement to affect deadbolt retraction and extension. A lever may be used to retract the latch in response to rotation of the first rotary control in a first rotational direction when the deadbolt is retracted by the first rotary control.

An exemplary pushbar assembly generally includes a mounting assembly, a latch control assembly movably mounted to the mounting assembly, a pushbar operable to actuate the latch control assembly, a master cam rotatably mounted to the mounting assembly, a slide plate, and an insert. The slide plate is slidably mounted to the mounting assembly, and is configured to move between a locking position and an unlocking position in response to rotation of the master cam between a locking orientation and an unlocking orientation. The insert is configured to limit rotation of the master cam to a predetermined angular range less than 360°.

A soap dispenser includes a structure in which an inner shell and an outer shell are slidably engaged together. An enclosed space is formed after the inner shell and the outer shell are engaged so as to accommodate and hold a refillable bottle or a disposable bag. The inner shell and the outer shell are fixed and locked with each other by a spring and a metal pin, and provided with engaging grooves on the back thereof so as to enhance the connection strength, and allow to be opened only by using a magnetic key. The soap dispenser solves the problems of poor anti-theft and tamper-proof effect, serious plastic waste, contamination caused by repeated filling, difficult maintenance, unattractive appearance, poor user experience, which are of great significance in enhancing the efficiency of the use of cleaning products in public occasions and the user experience.
