Abstract: A method for inspecting a lock set is to utilize a reception unit for receiving the signals from a lock set mounted at a door to inspect whether the door is closed and whether the lock set is locked or being broken.

Abstract: A method for providing a K2-enriched FU-LING extract is provided. The method comprises the following steps: (a) mixing a FU-LING with a solvent to provide a first mixture; (b) alkalizing the first mixture to provide a second mixture; (c) acidifying the second mixture to provide a third mixture, (d) alkalizing the third mixture to provide a forth mixture, wherein the forth mixture has a pH value of more than 7; and (e) neutralizing the forth mixture, wherein the K2 is at least one of tumulosic acid, dehydrotumulosic acid, polyporenic acid C and 3-epi-dehydrotumulosic acid.

Abstract: A lock cylinder includes a cylinder housing with a upper pin hole set and a replacing opening, a cylinder body with a lower pin hole set, a upper locking pin set, a second locking pin set and a clip member. The cylinder body is movably disposed inside the cylinder housing. The upper locking pin set is disposed inside the upper pin hole set for engaging the cylinder housing and the cylinder body. The second locking pin set is disposed inside the lower pin hole set for disengaging the cylinder housing from the cylinder body. The clip member constrains the cylinder body from sliding on the cylinder housing in a first position, and does not constrains the cylinder body from sliding on the cylinder housing in a second position. The cylinder body slides to a replacing position for replacing the second locking pin set via the replacing opening.

Abstract: A rekeyable lock includes a lock cylinder, a plug, a pin assembly and a stopper, the lock cylinder comprises a plug hole, a plurality of upper pin holes and a lower-pin-replacing hole, the plug is disposed at the plug hole, the pin assembly comprises a plurality of upper pins and a plurality of lower pins, the lower-pin-replacing hole selectively reveals the lower pins, the stopper is utilized for plugging into the lower-pin-replacing hole. When the stopper separates from the lower-pin-replacing hole, the lower-pin-replacing hole reveals the lower pins so as to replace the lower pins rapidly. When the stopper plugs into the lower-pin-replacing hole, the width of the stopper equals to that of the lower-pin-replacing hole. Otherwise, when the stopper separates from the lower-pin-replacing hole, the width of the stopper is larger than that of the lower-pin-replacing hole.

Abstract: A handle device includes a pivoting portion and a handle body. The pivoting portion includes a surrounding wall formed along a longitudinal axis, and the surrounding wall has a top surface. The handle body comprises an extending portion which protrudes from the pivoting portion along a radial direction perpendicular to the longitudinal axis and is apart from the top surface of the surrounding wall by a gap.

Abstract: A lock structure includes a lock cylinder, a plug and a pin assembly, the plug is within an accommodating space of the lock cylinder. The plug comprises an outer lateral wall, a plurality of first lower pin holes and at least one second lower pin hole, each of the first lower pin holes comprises a first blocking edge, the second lower pin hole comprises a second blocking edge, wherein a second depth defined between the second blocking edge and the outer lateral wall is smaller than a first depth defined between the first blocking edge and the outer lateral wall. By height difference between the position of the first blocking edge and the position of the second blocking edge, an unmatched key can not contact with the second lower pin under instantaneous bump to prevent an unlock situation. Therefore, the burglar proof function is achieved.

Abstract: A fire door lock structure includes a stopper disposed at a door frame and a latch assembly disposed at a fire door, wherein the latch assembly comprises a lock base, a latch unit, a blocking member, a pair of male and female means and a linking set. The latch unit includes a latch bolt. The latch unit and the blocking member are swingably disposed at an accommodating slot of the lock base. The blocking member is fastened at the stopper by the pair of male and female means, wherein the male means comprises a fastener formed at the blocking member. In the locked state, the fastener of the male means can be fastened at the stopper to prevent the stopper from being unable to block the latch bolt caused by a deformed fire door or deformed door frame under a fire condition.

Abstract: A latch structure of fire door lock includes a lock base, a latch unit, a blocking member, an elastic member and a linking set. The lock base comprises an accommodating slot, a first lateral portion having a first sliding slot, and a second lateral portion having a second sliding slot. The latch unit has a combining pin. The blocking member is disposed in the accommodating slot and includes a contacting portion. The contacting portion is pressed by the elastic member. The combining pin is connected at the linking set and the latch unit. Two end portions of the combining pin are slidably disposed at the first sliding slot and the second sliding slot respectively. The end portions of the combining pin are restrained within a first recess of the first sliding slot and a second recess of the second sliding slot respectively.
