Description

Strongbox is closed the door automatic locking device

Technical field

The present invention relates to the vitals on strongbox, particularly a kind of strongbox is closed the door automatic locking device.

Background technology

People are after use strongbox, though can be shut by door leaf, often forgetting locks again locks completely by strongbox, thus leaves hidden danger at once, cause in strongbox to deposit object and lose, and bring very large economic loss and mental burden to user.

Number of patent application 201410203464.2 " a kind of safe deposit box or strongbox electromagnet opening device ", only provides opening device.

The patent No. 201020553387.0 " a kind of strongbox of energy automatic opening and closing door ", though be a kind of strongbox of energy automatic opening and closing door, but its complex structure, there are tripping spring, push rod spring, pushing block spring, the multiple spring part of interlock spring, and utilize electromagnetic valve lock to close, also need during enabling to input password.

Summary of the invention

Technical problem to be solved by this invention is: provide a kind of strongbox to close the door automatic locking device, its structure is simple, will be automatic locking as long as close the door, and avoids forgetting the hidden danger of locking and bringing, add the safety in utilization of strongbox, and use more convenient, quick.

The present invention's adopted technical scheme that solves the problem is: strongbox is closed the door automatic locking device, comprise and the upper of keeper is installed, lower connecting plate is fixed on, on lower link, the fixed head being provided with keeper is fixed on slide plate, on slide plate first, second tooth bar respectively with first on slide plate, second gears meshing, first gear is also with upper, a left side on lower plate, right tooth bar engagement is integrally formed, described door-plate is fixed with the locking plate seat of base and band locking plate, fixed bar two ends with spring are connected with base and slide plate respectively, described locking plate coordinates with the locking plate groove on door-plate and lower connecting plate.

Compared with prior art, the invention has the advantages that, this automatic locking device, structure is simple, part is few, on the door-plate of former strongbox, only open a locking plate groove, the top of locking plate groove increases the locking plate seat of a band locking plate, and locking plate and lower connecting plate, locking plate slot fit, fixed bar with spring is connected with slide plate and base respectively, as long as shut door-plate, locking device on door-plate will be automatic locking by Safe lock jail, thoroughly avoid user to close the door but forget the hidden danger of locking and bringing, add the safety in utilization of strongbox, reliability, because decreasing the program of locking, use more convenient, fast.

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiments of the invention are further described.

Upper and lower connecting rod 1,11 is respectively the strip that there is bending strip and lower end, upper and lower connecting rod has waist through hole 1-2,11-2 of identical, corresponding band left and right tooth bar 1-1,11-1 and chute 1-3,11-3 and installing hole, as shown in Figure 4, Figure 5.

Base 18, is weldingly fixed on door-plate 12 back side, and on fixed bar 17, cover has spring 16, and spring one end connection opening pin 15 is located, in the through hole on the two ends difference inserted base 18 of fixed bar and in the flange 6-1 through hole of slide plate 6 one side.

Upper and lower junction plate 19,14 is the angle steel shape of an identical lateral buckling.

The upper end of upper connecting rod 1, the lower end of lower link 11, be screwed with on the upper and lower junction plate 19,14 of keeper 2, the other end of upper and lower connecting rod overlaps together, cover slide plate 6 on the surface, and connecting into entirety with the first, the 3rd column 3,9 by chute 1-3,11-3 corresponding on upper and lower connecting rod, each column moves up and down along each chute.

First gear 4 is arranged in waist through hole 1-2,11-2, is fixed on the second column 5, and is connected with a joggle integral with left and right tooth bar 1-1,11-1 on upper and lower connecting rod and slide plate and the first tooth bar 6-2.

The outside of slide plate 6 is fixed on the keeper fixed head 10 with keeper 2, it is connected with the second gear 8 and engages with the second tooth bar 7, and the second gear 8 is fixed on (figure does not draw) on handle, and the second tooth bar 7 is screwed on slide plate 6, as shown in Figure 1.

Locking plate 13, for there is installing hole upper end, there is buckle 13-1 centre, the strip of the lower end side of being plane head 13-2, locking plate bearing pin 21, cottor pin are connected in the installing hole on locking plate seat 20, and can rotate along the bearing pin 21 on locking plate seat, as shown in Figure 6.

Locking plate seat 20 is weldingly fixed on below door-plate 12 and between the top of lower connecting plate 14.

On the bottom of door-plate 12, a through hole is had to be locking plate groove 12-1 relative to the cooperation place of locking plate 13 lower end, as shown in Figure 2.

When closing door state, all keepers 2 are in the state of stretching out, and insert in door frame of box 22, and the square plane head 13-2 of locking plate 13 lower end is under the effect of door frame of box 22, and pressed down and sink in the locking plate groove 12-1 of door-plate, at this moment spring 16 is in relaxed state.

When user opens the door with hand turning handle, the second gear 8 on handle is by engaging the second tooth bar 7 on slide plate with it, slide plate 6 is driven to slide left, slide plate moves drive first gear 4 and rotates, thus drive left and right tooth bar 1-1, the 11-1 on the upper and lower connecting rod that engages with it, make the upper and lower movement of upper and lower connecting rod 1,11, lower connecting plate moves up, after all keepers 2 are condensed to door-plate completely, door-plate just can be pulled to open strongbox.

Be about at closing time, the buckle 13-1 on locking plate is just stuck on the folding edge 14-1 of lower connecting plate, and locking plate can not be moved by card, and the spring 16 at this moment door installed is in compress energy storage state, as shown in Figure 3 a.Door continues to shut, doorframe 22 withstands locking plate and is pressed in the locking plate groove 12-1 bottom door-plate by the square plane head 13-2 below locking plate, locking plate 13 rotates a low-angle simultaneously, the buckle 13-1 on it is made to depart from the contact with lower connecting plate folding edge 14-1, at this moment keeper 2 is just to the bolt hole on doorframe 22, as shown in Figure 3 b.

Under the effect that dynamic slide plate 6 slides tried hard to recommend to the right by spring 16, the first tooth bar 6-2 on slide plate, the second tooth bar 7 drive first, second gear 5,8 clockwise direction engaged with it to rotate, and drive the left and right tooth bar on the upper and lower connecting rod that engages with it, upper and lower connecting rod is moved up and down, until design attitude stops.

At this moment all keepers 2 all extend in the bolt hole on doorframe 22, door-plate pins by automatic locking device automatically, locking plate 13 departs from lower connecting plate 14 completely, meanwhile, the second gear 8 on handle also synchronously gets back to pass door state, complete strongbox pass self-lockingly to operate behind the door, as shown in Figure 3 c.
