Description
Technical field
The present invention relates to a kind of interlock and locking device of drawer.
Background technology
Current traditional case, a plurality of drawers of cabinet and table and so on article are generally controlled by a lockset, when lockset is opened, all drawer can operate in each drawer of state to be opened in opening and closing, otherwise, must be after closing all drawers, can lock lockset, there is at present a kind of drawer that once can only open anti-many opening structures of a drawer, this drawer is provided with an anti-device of avoiding on the siding track of drawer, this device is adopted made of plastic, structural strength is not high, and be easy to damage, if this installs damage, anti-many opening structures are just inoperative, and the locking device structure of this kind of interlock is very loaded down with trivial details.
Summary of the invention
The object of the present invention is to provide and a kind ofly once can only open a drawer, and compact conformation, can self-locking, the interlocking of the drawer of long service life and locking device.
In order to achieve the above object, technical scheme of the present invention is: a kind of interlocking of drawer and locking device, its innovative point is: comprise installing plate, jointed shaft, plural interlocking sheet, three above interlocking bars, extension spring and stop tab, jointed shaft is fixedly connected with installing plate, installing plate is provided with spacing hole and interlocking bar banking stop, one end and the jointed shaft of interlocking sheet are hinged, the other end is through spacing hole, and stretch out outside installing plate, and the other end of interlocking sheet is provided with locking plate groove, stop tab is fixedly connected with installing plate, what more than three interlocking bars was tight against successively is inserted in the space forming between interlocking bar banking stop and installing plate, and adjacent two interlocking bars place that offsets is corresponding with a position that interlocks sheet, in three above interlocking bars, interlocking bar and stop tab bottom offsets, interlocking bar topmost and one end load of extension spring, the other end of extension spring and installing plate load, when interlocking sheet moves in spacing hole along jointed shaft, interlocking sheet can insert between two adjacent interlocking bars, what interlock bar is provided with inclined-plane with interlocking sheet contact position,
Locking device comprises stay, back-moving spring and with the middle control lever of warpage section, installing plate is provided with stay accommodation hole, stay inserts in stay accommodation hole, stay is provided with middle control lever and stretches into hole, spring accommodation hole and stretch into the protruding tongue in spring accommodation hole, back-moving spring is sleeved on protruding tongue, and one end and installing plate offset, the other end and stay offset, the two ends of middle control lever are all contained on drawer casing, and stretch into hole through middle control lever, and warpage section is arranged in control lever and stretches into place, hole, when central control lever is rotated, the warpage section of middle control lever can make stay move in stay accommodation hole, and the bottom of stay is provided with dodges slot, when interlocking sheet moves in spacing hole along jointed shaft, the interlocking bar of close stay can stretch into dodges in slot.
Described installing plate is U-shaped, and one of them side plate of installing plate is provided with flange, jointed shaft inserts in flange, and fixing be fixedly connected with installing plate, the spacing hole of installing plate is positioned on another side plate of installing plate, interlocking bar banking stop is fixedly connected on the inner side of another side plate, and and this side plate between be formed with space.
On described installing plate, be also provided with spring fitting plate, the other end of extension spring and the load of spring fitting plate.
Adopt after said structure, due to when interlocking sheet rotates in spacing hole along jointed shaft, interlocking sheet can insert between two adjacent interlocking bars, therefore when the present invention is arranged in the casing of drawer, as long as fill a stator on drawer, this stator stretches in the locking plate groove of interlocking sheet, and can drive interlocking sheet to move in spacing hole along jointed shaft, when drawer is closed, the stator of each drawer all stretches in the locking plate groove of interlocking sheet, after one of them drawer is opened, stator just will make to interlock sheet and rotate along jointed shaft, interlocking sheet inserts between two corresponding interlocking bars in rotation, interlocking bar at this more than interlocking sheet produces top offset in the gap between interlocking bar banking stop and installing plate, after these interlocking bar displacements, the interlocking bar that other are adjacent also moves up thereupon, after interlocking bar moves, when wanting to open other drawer, the interlocking sheet of this drawer just can not be in the middle rotation of pulling of stator, because interlocking bar has produced movement, interlocking sheet is inserted and is not entered between adjacent two interlocking bars, therefore just reached the object that prevents that other drawer is opened, and the present invention is not mounted on the sliding rail of drawer, do not affect the movement of drawer, improved application life, structure is compacter, and each component all adopt stainless steel manufacture to form, further improved application life, and when drawer need to be locked, as long as control lever in rotating, the warpage section of middle control lever can make stay move in stay accommodation hole, and the bottom of stay is provided with dodges slot, when interlocking sheet moves in spacing hole along jointed shaft, the interlocking bar of close stay can stretch into dodges in slot, therefore can not affect the unlatching of drawer, and central control lever is when rotate, the warpage section of middle control lever can make stay move in stay accommodation hole, and the bottom of stay makes near the interlocking bar of stay spacing, making to interlock bar can not move axially, after interlocking bar can not move, just limited the rotation of interlocking sheet, drawer just can not opened naturally, therefore there is locking function.
