A lockable case includes a base casing having two opposite first lateral walls, a top cover openably connected to the base casing, a slide block, and two slide bars disposed respectively on two opposite sides of the slide block. Each slide bar has an inner end, and a locking element to engage a corresponding first lateral wall. The slide block is disposed between the inner ends of the slide bars, and is movable between locking and unlocking positions that respectively prevents and permits inward movement of the slide bars. An actuating lever is connected pivotally to the slide block to move the slide block to the locking position. An elastic member is provided for biasing the slide block toward the unlocking position.

A locking device comprises a housing (4), a bolt means mounted in the housing and an intermediate member connected to the bolt means and adapted for an essentially rectilinear movement back and forth between a first end position, in which the bolt means is retracted, and a second end position, in which the bolt means is extended. The locking device also comprises a latch means restricting the movement of the intermediate member when a proper code card has not activated the locking device. A cassette (10) , which is integrated with the intermediate member and has a card space (12) for reception of the card in a position that activates the locking device, is provided with a frame (17), which fully hides the card from the outside when the bolt means is extended.

A lock for locking a movable member to a fixed member, wherein the movable member has a recess, and wherein the fixed member has a threaded through bore. The lock includes a head, a stem, first locking apparatus, and an optional second locking apparatus. The head is for selective rotational resting in the recess in the movable member. The stem selectively movably depends from the head and is for selectively engaging in the threaded through bore in the fixed member. The first locking apparatus selectively prevents rotation of the head relative to the stem to thereby prevent rotation of the stem and withdrawal thereof from the threaded through bore in the fixed member to thereby selectively prevent removal of the lock from the fixed member. The second locking apparatus depends operatively from the stem, is operatively connected to the first locking apparatus, and is for selectively preventing retraction of the stem from the threaded through bore in the fixed member to thereby further selectively prevent removal of the lock from the fixed member.

The present invention, in a non-limiting example embodiment provides a locking apparatus and method for securing locking hardware without the use of a key. In an example embodiment, the apparatus comprises at least a keyless insertion rotatable disk-style, barrel locking apparatus that, in a locked state can be inserted into a securing device without first unlocking, and then, thereafter, locking after insertion. In a nonlimiting example embodiment, unlocking and re-locking requires a key. The present invention, in an example embodiment, also provides features that allow the locking apparatus to enter and exit multiple apertures without requiring a key.

The invention relates a composite coded lock for a bag, said lock comprises a central lock hook in the middle, at least one side lock hook, a bottom shell, a locking device, a clamping device and a linkage, wherein the locking device is fixed on a casing and has a key lock and a coded lock; the coded lock has a controlled lock blade which has a limiting portion; the limiting portion is controlled by the key lock and the coded lock to move between an unlocking position and a locking position; the clamping device has a clamping pedestal fixed on one side of the bottom shell; the clamping pedestal is provided with a locking piece clamped with the side lock hook and a push and control block used for controlling the movement of the locking piece; the linkage is arranged on the bottom shell.

The invention discloses a mechanical lock and relates to the technical field of lock manufacturing. The mechanical lock comprises a lock body and a lock cylinder, wherein the lock cylinder is installed in a sliding way in the lock body, the lock cylinder is a hollow tube, a baffle is arranged in the middle of the lock cylinder in the axis direction and divides an inner cavity of the lock cylinder into two symmetrical halves, lock pin sliding ways with even numbers are arranged on the baffle and are symmetrically arranged towards two sides of the baffle with the central point of the baffle in the length direction as the basic point, and lock pins are installed in the lock pin sliding ways. A plurality of lock pin inserting grooves butting against external ports of the plurality of lock pin sliding ways in the lock cylinder when the lock cylinder rotates to the locking position in the sliding ways are arranged on the lock body, and the lock pin inserting grooves are symmetrically arranged with the central points of the sliding ways as the basic point. The lock pins are in a '+' shape, and transverse edges of the lock pins extend out from two sides of the baffle. A gear is sleeved on the middle section of the lock cylinder, the gear is installed in a gear groove on the lock body, the gear is meshed with a rack, and two ends of the rack extends out from rack holes on two sides of the lock body. The mechanical lock requires fewer parts and is strong in illegal unlocking prevention capability.
