Description

Theft-proof interlock for drawers

The utility model relates to a kind of " the antitheft interlocker of drawer ", and this interlocker is the protection drawer, and a kind of novel anti-theft technology of many drawers of interlocking again is widely used in the iron wood structure furniture of various many drawers.

The utility model is poor with reference to domestic multiple desk, archive cabinet survivability, easily steals money and goods or files, so at this difficult problem, form through studying repeatedly, testing.

The purpose of this utility model provides a kind of usefulness one that drawer-lock is controlled many drawers, has both saved the medicine lock, can keep furniture specious again, mainly is that protection the country and people's property is difficult for stolen.

Common most of desk or data cupboard are with a plank hinge to be installed in the hired thug side, use the iron sheet hasp, common padlock is locked controlled many drawers.Control many drawers with such method, though it is simple, but theftproof performance is poor, robber person is as long as prize hinge or plank, iron sheet hasp bad with simple metal tools, only need 1～2 minute crime time, just money and goods can be stolen, appearance is blocked many drawers with a plank, concerning modern furniture, it is unbecoming also to seem.Some desk or closet are installed drawer-lock, though drawer-lock is better than iron pad lock theftproof performance, but weak point is arranged, robber person is with the bad 1～1.5mm of wooden chapelet sled above the drawer-lock, drawer will be opened, or aims at lock core with metal bar and dash the lean-in Dou of whole lock body, little dead bolt has just left wooden support upper groove, and drawer just is opened.Why is drawer-lock pried open easily? through research practice discovery for several times, the dead bolt of drawer-lock own is shorter, dead bolt is thin again, lock body is installed in drawer face inwall, and lock core is equal with the drawer outside, and drawer face general thickness is at 22mm, and majority is that pine is made, wooden construction soft texture, a drawer face inwall cutter rectangular recess, an outside cutter circular hole and groove communicate, the drawer lock body is installed, four wood screw holes are arranged on the lock body, and near the rectangular recess edge, wood screw is again little, stressed insufficient strength, add wooden softly, cause robber person to destroy easily, the colleague also seeks energetically, research is explored and is solved this difficult problem.

The utility model is achieved in that it is made of three parts.First is a controller, controls driving link by the rotation pressing plate and can locate.

Second portion is a driving link, has the root locking bar to be installed in and rotates below the pressing plate, rotates pressing plate and turns left 90 °, and driving link is upwards stirred, and lock pin protects draw-in groove with regard to having left the spill of taking out Drawer side on the locking bar, and drawer just can freely be pulled out; When drawer is closed, locking bar to be stirred downwards, lock pin just is stuck in spill and protects in the draw-in groove, and the rotation pressing plate rotates 90 ° again and is pressed on the locking bar, and just with drawer locking, drawer just can't be opened.

Third part is the drawer-lock anti-theft device, main by antitheft clamp, protect the anti-skid plate of lock, snap close pick-proof baffle plate is formed.These antitheft materials; all be to make, be installed in the outside and the inside of drawer face, the timber of drawer face and the position of drawer-lock are reinforced up and down with steel plate; prevent that robber person from prizing the drawer-lock position badly or washing out with the metal tool used in crime, plays the safe antitheft performance of protection drawer.

Should " the antitheft interlocker of drawer " only with one drawer-lock, control the novel anti-theft technology of many drawers, simple in structure, manufacturing, installation, use all make things convenient for, and good anti-theft effect makes the furniture of the many drawers of iron wood structure specious, unaffected, as long as punch press, drilling machine and simple tools are arranged, the common laborer trains a little, just can make and install.

The concrete structure of utility model is drawn by following embodiment and accompanying drawing thereof:

Fig. 7: spill is protected card stereogram Fig. 8: operating principle is installed three-dimensional diagrammatic sketch

Among Fig. 1: 1, fixed head; 2, rivet; 3, rotate pressing plate

1. fixed head is the iron plate of the rectangular shaped that forms of a kind of flanging, and there are four wood screw holes the side, is screwed wooden chapelet sidewall under desktop, but fixed head 1. with rivet 2. riveted joint movingly rotate pressing plate and 3. rotate 3. 90 ° of left-right rotation of pressing plate.

Among Fig. 2: 4 locking bars: 5 lock pins:

4. locking bar is to make with a band iron, respectively there is a long lumbar hole to go here and there up and down between them, the band iron top is converted into 90 degree right angles, just in time with rotate pressing plate 3. length match, locking bar 4. length dimension is determined according to the drawer number, locking bar is equipped with lock pin on 4. and 5. is used for locking drawer specially, 5. lock pin is determined by the drawer number, 4. locking bar has two long slots up and down, with half knob screw, spring washer is installed in the wooden block support, can go here and there up and down, take out Drawer side and cut a hole into the trough (see figure 7) of recessed worker's shape and spill is protected card 6. be installed in the groove with wood screw.4. toward next pressure, 5. lock pin just in time is stuck in spill and protects card 6. in the groove with locking bar, more 3. the rotation pressing plate of controller is stirred to be pressed in locking bar and 4. to go up, and 4. locking bar is locked, and drawer just can't be opened.

Among Fig. 3: 1. the antitheft clamp 1. 2. antitheft clamp of wood screw is to use the steel plate drawing, being stuck in the drawer-lock back side matches, 2. be fixedly mounted in drawer face inboard with wood screw, prevent the impact or the sled of tool used in crime, can play certain security personnel's effect lock core.

Among Fig. 4: protecting the anti-skid plate of lock 3. is the steel plate that strikes out right angle 90 degree, the trough that there is individual concave shape top centre; being installed in the drawer face is close to the dead bolt position and matches; another side is in drawer face outside; protrude one above; exceed the drawer plane, below the slot of two symmetries is arranged is Agnail type nail nail hole 4.; two nails have lock core hole in the middle of the holes, protecting the anti-skid plate of lock, 3. to be that the timber of protection drawer face is difficult for by the tool used in crime sled bad, the safety of main protection lock.

Among Fig. 5: there are two hangnails Agnail type nail centre 4., 3. with the anti-skid plate slot 5. of snap close 4. Agnail type nail is hammered into shape into along protecting the anti-skid plate of lock, shrinks and the principle that expands according to timber, and this nail is more stressed firmly than wood screw, and the pick-proof performance is good.

Among Fig. 6; 5. the anti-skid plate of snap close is the steel plate drawing; be converted into right angle 90 degree; be installed in the recessed block length trough in wood chapelet above and below, drawer top; just in time and protect the anti-skid plate of lock and 3. go up convex surface and match; become an overall structure, make metal tool used in crime sled, reach protection drawer face again and be difficult for by the bad fastness of sled at the timber position on every side less than dead bolt.
