摘要:
A key includes a shank having at least one groove and at least one recess, and the at least one groove has different lengths. At least one magnetic member is received in the at least one recess and a number of the at least one magnetic member is not more than a number of the at least one recess. The arrangements of the at least one recess, the at least one groove and the at least one magnetic member have multiple options. The magnetic members are located in different recesses and the magnetic poles of the magnetic members are arranged in different ways. The key is difficult to be copied and has higher safety standards.

A lock includes a housing having an insertion hole in which a pivot is inserted. A slide is connected to one end of the pivot. A spring is located in the insertion hole and applies a first resilient force toward the insertion hole, and a second resilient force toward a direction that the slide pivots. When the slide is located at a first position, the installation recess is covered by the slide to prevent water and dust from entering into the installation recess. When the slide located at a second position, at least one portion of the slide does not cover the installation recess to allow the lock to be unlocked. When the slide located at a third position, the slide is located higher than the first end face of the protrusion and is pivotable so that the installation recess is explored for convenience of replacement of the core.

A lock includes a housing having an axial space and multiple radial top pin holes. Multiple through holes are defined through the housing and located corresponding to the space. A core is located in the space and has multiple radial bottom pin holes which communicate with the top pin holes respectively. A key hole is defined in the first end of the core and a connection member is connected to the second end of the core. The key hole communicates with the bottom pin holes. The housing has a connection portion located corresponding to the connection member. The through holes are located alternatively to the bottom pin holes. When the bottom pin holes are rotated to the through holes and the core moves axially, the connection member is connected to the connection portion. The through holes communicate with the bottom pin holes.

A lock assembly includes an outer casing (10) with a core (20) rotatably received therein. A plurality sets of locking units are received in alignment passages (11,21) in the outer casing (10) and the core (20) which has a key hole (22) communicating with the passages (21) in the core (20). A magnetic piece (43) is received in a sleeve (41) and biased by a spring, the magnetic piece (41) movably received in one of the alignment passages (11,21) of the outer casing (10) and the core (20). The key (50) has a plurality of recesses (51) and can be inserted in the key hole (22) in the core (20) to allow the sleeves of the locking units to be lowered into the recesses. A magnetic member (52) is received in the key (50) and attracts the magnetic piece (43) toward the key (50) to result in a new position for the locking units and the magnetic piece (43) to allow the core (20) to be rotated.

A window lock assembly includes a fixed piece (1) and a shaft (2), which is pivotably connected to the fixed piece. A number lock (3) is connected to the shaft (2) and a knob (35) is movably connected to a pin (33) of the number lock (3). A plurality of numbered rings (34) are mounted to the pin (33). The knob (35) has side walls which are disengagably engaged with a retaining slot (10) in the fixed piece (1). The pin (33) has two protrusions (331) which are movably engaged with two curve slots (351) in the two side walls. Each curve slot (351) has a high section and a low section such that the pin (33) with the ring can be pulled upward to set the number so as to allow the user to pull the knob to lock or unlock the number lock (3).
摘要:
A lock includes a body with a lock cylinder and a knob on two ends of the body. A cam is located between the lock cylinder and the knob. The lock cylinder includes a transmission member is pushed by resilient element toward the cam. The knob includes a shaft. A spring, an engaging member and a driving member are located to one end of the shaft. The engaging member includes a contact portion with a head. A first housing is connected to the body and includes a stop unit. In an initial position, the driving member contacts the transmission member. The end block resiliently contacts the head. In a locked position, the end block is located between the shaft and the head to restrict the engaging member from being pushed by the lock cylinder so that the lock is automatically locked. The knob is axially moved to unlock position.
