Abstract

The utility model relates to a safety latch of a safe, which is composed of a latch head and a latch seat. The latch head is connected inside a buckle sleeve by a latch button with a locating stud. The latch seat is of a connecting plate. Fixed rod grooves which correspond to each other are arranged on the two side faces of the connecting plate; wherein, one side face is provided with a locating stud chute. The locating stud on the latch button is matched with the locating stud groove on the connecting plate to connect the buckle sleeve and the connecting plate into a whole. The safety latch works only by that the buckle sleeve with the safety button uses the locating stud to move inside the locating stud groove, thereby leading the latch button to reach out and match with the safety latch of the door frame and lead the latch button to shrink into the buckle sleeve. The utility model has the advantages of simple structure, few parts, easy processing and manufacturing, easy assembly and low cost. When the door is closed, the two supporting angles of the front end of the safety latch button firmly fasten a latch hole. An obstacle is formed between the door latch and the latch hole. The two supporting angles can not be extracted, thus the safe can not be opened. The safety performance of the safe is greatly strengthened. The anti-theft effect is good. The safety latch can be used together with various safes and band deposit boxes.

Description

Strongbox safety bolt

Technical field

The utility model relates to the safety device on a kind of safety cabinet, the safe deposit box, and particularly a kind of have tamper-resistant function, a strongbox safety bolt safe in utilization, can be installed in to strengthen facility as safety on safety cabinet, the safe deposit box and use.

Background technology

The safety latch that has now on commercially available a lot of safety cabinets mostly is square door bolt or circular door bolt, and the corresponding section has square or circular door bolt hole on doorframe, safety latch directly inserts in the door bolt hole on the doorframe, no any barrier structure between bolt and door bolt hole, therefore seize the opportunity when forcing open the door frame as the lawless person, after the effect that doorframe, framework, safety latch are subjected to external force can be distorted and be deformed into to a certain degree, be easy to make the door bolt hole on the bolt disengaging doorframe and skid off, thereby open safety cabinet the lawless person is taken advantage of a weak point, so the safety of the safety latch of this kind structure not enough.

Number of patent application CN200610053086.X " a kind of antitheft safe door ", though a kind of patent application with reinforced safety door security measures also is provided, increased the difficulty that safety cabinet is prized, it has the guide pillar of an evagination at the middle part of side latch head sidewall, be fixed with lateral confinement position guide pin bushing at the door body back side, lateral confinement position guide pin bushing front end has a helical guide groove that can supply the guide pillar slippage and force side latch head to rotate, the rear end has spacing straight trough, the boss that the sidepiece of side latch head front end has evagination is embedded with the side latch head cover in lateral crossbar opening, side latch head puts and has the boss groove, in the time of in side latch head inserts lateral crossbar opening, boss and boss groove are mutually certain angle, have only when guide pillar is positioned at spacing straight trough, boss is parallel with the boss groove, promptly there is the boss on the side latch head to be blocked in the inner surface that side latch head overlaps, side latch head can not be deviate from from side down hole easily, strengthen the safety of security door and played antitheft effect, but its part is many, structure is complicated, processing, assembling is trouble, and that the doorframe volume takies the confined space greatly is big, the manufacturing cost height.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of strongbox safety bolt is provided, is installed in and has tamper-resistant function, good anti-theft effect on the safety cabinet, and simple in structure, part is few, easy processing, assembling, cost of manufacture are low.

The technical scheme in the invention for solving the above technical problem is: strongbox safety bolt is made up of door bolt head and door bolt seat, described door bolt head is linked by the door bolt that has alignment pin and is connected in the retaining ring, described door bolt seat is a junction plate, corresponding fixed bar chute is arranged on the two sides of described junction plate, wherein also has the alignment pin chute on the side, the alignment pin that described door bolt is buckled cooperates with alignment pin chute on the junction plate, retaining ring and junction plate is flexibly connected whole.

Compared with prior art, advantage of the present utility model is: safety latch is only fastened the retaining ring of button with a bolt or latch with moving in the alignment pin chute of the alignment pin on it on junction plate by band, make door bolt button stretch out with doorframe on the safety latch cover cooperate or fasten with a bolt or latch to buckle to be reduced to and make its operate as normal in the retaining ring, it is simple in structure, part is few, easy processing and fabricating, easily assembling, cost is low, can with the safety cabinet of various different structures, the supporting use of safe deposit box, two strut angles of safety latch door bolt button front end tightly fasten the door bolt hole at closing time, forming obstacle between bolt and door bolt hole can not deviate under external force yet, safety cabinet just can't be opened, strengthened the safety of safety cabinet greatly, good anti-theft effect.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

One end of alignment pin cramp 11 has bending, has fastened alignment pin 6 in the through hole in the bending.

Five cramps 10 and a slice alignment pin cramp 11 usefulness pins are fixed into independently one group of door bolt button 5, with two door bolt button pins 1 two groups of door bolt buttons 5 are fixed on the retaining ring 2 again, door bolt button 5 can also rotate around fulcrum door bolt button pin 1, through hole 3 is arranged in the middle of the retaining ring lower limb, also with two sides support fixation in aggregates gain in strength of rivet 12 with retaining ring 2, as shown in Figure 3, the repeatedly pressing buckle piece number of door bolt button 5 can be selected as required.

In the middle of junction plate 9 one sidewalls long waist shaped hole being arranged is fixed bar chute 4, and corresponding fixed bar chute 4 is arranged in the middle of another sidewall, and both sides also have the alignment pin chute 7 of symmetry, has two installation screws to be screwed on stool plate 16 on the end face.

It is middle that the retaining ring 2 that assembles is inserted junction plate 9, alignment pin 6 on it is inserted in the alignment pin chute 7, upper and lower slip in the alignment pin chute, junction plate 9 lower limbs also are integral the intensity that can increase junction plate 9 with rivet 8 with junction plate 9 support fixation for two jiaos, shown in Fig. 1,2,3,4,5, constitute safety latch 17.
