Background technology

At various maintenance industries, workplaces such as workshop appliance all need deposit various tool usually, and the drawer of tool car are made up of multilayer.Pin drawer a central controlled lock must be set, and will open drawer, must open central controlled lock.The advantage of this lock is that the entire tool car has only a central controlled lock, and that also has only a key, carries easily, be difficult for losing, and single drawer can locate good locking states under the control of central controlled lock, and the instrument of depositing in the drawer is in good keeping.But prevent that single the opening naturally of drawer from must pin central controlled lock, some trouble operates.

Summary of the invention

The purpose of the utility model provides a kind of lock of tool car drawer, and it can not must can open each layer drawer with key, but uses up the back with automatic blocking drawer under external force or the action of reset spring, prevents outer sliding.

The technical characterictic of the utility model is that box body is arranged, and pasting the place, top in the box body has an inner chamber, is provided with the slide-bar device in the inner chamber; The slide-bar device be the end towards the sky, waist is downward; Dead bolt on the slide-bar device can pass through box body left side upper lock tongue and import and export, and is outside equipped with the slide block PBU pushbutton unit in the box body bottom, and the belly of said slide block PBU pushbutton unit up; And the slide block of this device inserts through pulley place in the box body, lid is set and makes its sealing at the box body rear side.

The above box body is a cuboid framework; Be provided with dead bolt imports and exports in its place ahead; Therein section be provided with a side locating piece to slide-bar, to the anti-spin-block of slide-bar, to the limited block of the pulley on the slide-bar, to the fixed mount of the spring of slide block button and the screwed hole of box body.

The slide-bar device of the utility model has slide-bar; At the front end of slide-bar the inclined-plane of one dead bolt and dead bolt is arranged, dead bolt reaches on the baffle plate of lock body front end through the import and export of the dead bolt of box body, makes lock be in locking states; Slide-bar is provided with locating piece, slide block slot; There is pulley fixed frame terminal both sides at slide block slot, respectively have an aperture to erect pulley in the middle of the said pulley fixed frame, and this pulley is fixed on the middle aperture of two pulley fixed frames through pulley spindle; The rear section of slide-bar is provided with anti-spin slot, is provided with spacing ladder of spring and spring at the tail end of slide-bar.

The slide block PBU pushbutton unit of above the utility model has fixed mount; Fixed mount is a cuboid, is provided with plug above the two ends at it, is provided with slide block in the centre position of two plugs; Slider side wall is provided with limited block, and the place is provided with the spring holddown groove respectively in the slide block both sides.

The lid of the utility model is a pane of sealing the box body side; The opposite side locating piece that pair slide-bar is arranged on the lid medial surface; The locating piece of both sides is fixed in moving of the big orientation of slide-bar; The fixed mount locating piece is limited to the generous displacement in the slide block button left and right sides and moves, spring top limit piece, and this setting is limited to the spring top and moves the screwed hole that reaches lid.

Operating principle be the slide block button of the utility model under the effect of external force, slide block and pulley are slided mutually promoted slide-bar and rearward move, thereby make the dead bolt dead bolt of having withdrawn import and export and just can freely open drawer.Do not having external force to do the time spent,, letting the state of lock place locking, preventing that drawer from skidding off naturally because the elastic force effect of slide-bar rear spring makes dead bolt stretch out dead bolt naturally and import and export.

The utility model has the advantages that it can not must can open each layer drawer with key, closing drawers automatically after using up prevents outer sliding.
