Abstract: A mechanism for releasably locking a drawer and preventing the drawer from inadvertently slipping out of its recess includes a user-accessible bar that actuates locking hooks to release the drawer from a locked position.

Abstract: This invention involves a type of pneumatic non-load quick dual-speed hydraulic jack, of which, the small of piston ring (17) of hydraulic pump cylinder integrates with pump body (19) and external ring of step pump core (14) to form movable assembly; the middle part of step pump core (14) is provided with pump core step interface (8); the step hole on the same axis of pneumatic valve block on special pneumatic valve structure is provided with washer (48), button (49), pneumatic valve core (45), compressed spring (68) and valve core securing seat (46). The available effect of this invention is stated as follows: the pump core interface used for conversion of hydraulic speed is characterized by the excellent process and low cost; the pneumatic valve parts specially provided for the jack can replace the hydraulic quick pump structure partially when the high-pressure air source is available.

Abstract: This utility model relates to a type of multi-function tool box with side doors, consisting of a base with foot wheels, head plate, left and right side boards, box body formed by a group of drawers, and handle. Drawers in the box slightly draw back at left and right sides. At rear of the box, fixed left and right side boards are provided. In available space formed between fixed external side boards and left/right drawn back drawer side plates, parts container is provided. At left and right side of drawers in front of this available space, left and right side doors that can be opened and function as part of left/right side board and part of front board of the box. On internal walls of these side doors, tool hanging plates with holes are provided. When these side doors move outward, the tool box is open; when they are withdrawn, an enclosed box is formed.

Abstract: This utility model relates to a lever type tool box drawer locking mechanism, consisting of control mechanism comprising shaped strip stressed plate, strip square shaped stressed plate guide rails with strip-shaped notch on main surface, guard sleeve covering and fitted on stressed plate guide rails, baffle with position-limiting extending hole and box cover plate, and actuator comprising lever with middle shaft mounting hole and waist shaped shaft mounting holes at both ends, lever seat with shaft mounting hole on middle raised face, locking plate with position-limiting locking hole and shaft mounting hole, locking plate guide rails with strip-shaped notch on main plane, and latch hook with protruding hook. The control mechanism and locking actuator are installed inner surface of tool box rear board and outer surface of drawer rear board respectively (near each other).

Abstract: This utility model relates to a type of position limiting mechanism preventing slipping out of drawers, consisting of arresting pin, keyway, self-plugging rivet, compression spring and control handle arranged in strip shaped drawer handle plate groove, and position-limiting pinch plate on box side board corresponding to keyway position. The arresting pin is strip shaped and consists of round pin rod and pin flap with shoulder. On the round pin rod, compression spring is fitted and on its tail end, control handle is fixed. The keyway is strip shaped with a round hole in the middle; at one outer side of its front end, an installation buckle with position-limiting buckle groove is provided, and on side face near the tail of the same side, fixed installation seat with internal assembling hole is provided. For operation, when the drawer is pushed inward, the pin flap will be automatically clamped.
