Description

The enclosed type safety lock

The safety lock that the utility model relates to belongs to lockset kind, is a kind of case type safety hanging locking specifically.

At present on the domestic and international market, the external application door lock, basically be padlock, and the production history of this class lockset reach decades always, even the longer time, form of structure does not have to change substantially, the chief drawback is does not reach that desirable require anti-of present people turned round for this padlock, pick-proof, anti-ly pound requirement, even if No. six maximum locks, also a sled is promptly opened easily, thereby be difficult to stop effectively the lock incident of forcing open the door brokenly to take place, bring many unsafe factors for society and family.

The purpose of this utility model is intended to improve above-mentioned technical deficiency, provides a kind of and anti-turns round, pick-proof, the anti-enclosed type safety lock of pounding.

In order to achieve the above object, the utility model is to realize by improving on the basis of existing technology, it comprises a lock body 1, lock core 8 is arranged in the lock body 1, latch arm hole 9, synchronous dead bolt 6, one tapered end 2 is arranged above lock body 1, the locking bar 3 that one symmetry is arranged on the tapered end 2, respectively there is the teeth groove 7 of a symmetry locking bar 3 lower ends, when lock is locked, locking bar 3 terminations are positioned in the latch arm hole 9, dead bolt 6 just coincide in the teeth groove 7 of two locking bars, 3 lower ends synchronously, be characterized in when the locking bar on the tapered end 23 is locked, at tapered end 2, the lock body outside lock chamber 4, a left side of establishing all around 1, right lock chamber 5 is on a left side, right lock chamber 4, the top respectively is provided with crossbeam 13 in 5, constitutes tapered end chamber 17 above two crossbeams 13, below two crossbeams 13, constitute lock body chamber 18, two lock chambers 4 about making, 5 form the sealing integral body of a closed shape, respectively establish a lock hole 10 in two crossbeams, 13 upright positions and corresponding position, locking bar 3 lower end, in lock chamber 4, a left side, dark screw 12 is respectively established with door bearing in right lock chamber 5.

Pound in order further to prevent, tapered end 2 tops are one oblique 11.

The utility model compared with the prior art, owing to adopted at tapered end, added lock chamber, a left side around lock body is outer, right lock chamber, make two lock chambers form the sealing integral body of a closed shape, having increased the anti-of lockset turns round, pick-proof, the anti-intensity of pounding, the more important thing is that the utility model has fundamentally changed lockset and prevented turning round, pick-proof, the anti-stress point of pounding, the antitheft stress point of its prior art lockset is on the section of the teeth groove of locking bar and dead bolt, so pick-proof power is very weak, the utility model is because with tapered end, lock body is enclosed in the cavity of two lock chambers, changed stress point, tensile strength than prior art improves more than 20 times, and the utility model is present a kind of more satisfactory safety hanging locking.

The explanation of accompanying drawing drawing:

1 lock body, 2 tapered ends, 3 locking bars, lock chamber, 4 left side, right lock chambers 5,6 synchronous dead bolts, 7 teeth groove, 8 lock cores, 9 latch arm hole, 10 lock holes, 11 is oblique, 12 dark screws, 13 crossbeams, 14 U-shape lock bars, 15U type cell body, 16 chassis, 17 tapered end chambers, 18 lock body chambers.

In order to understand better and to implement, it is as follows with the accompanying drawing to be that embodiment further specifies below:

Example 1, as Fig. 1, Fig. 2, shown in Figure 3, this structure comprises a lock body 1, one lock core 8 is arranged in lock body 1, latch arm hole 9, synchronous dead bolt 6, one tapered end 2 is arranged above lock body 1, the locking bar 3 that one symmetry is arranged on the tapered end 2, respectively there is the teeth groove 7 of a symmetry locking bar 3 lower ends, by the prior art process and assemble good after, chamber 4 is locked on a left side, right lock chamber 5 processes, lock chamber 4, a left side is identical with right lock chamber 5 symmetries, can adopt steel plate to manufacture, lock chamber 4, a left side, right lock chamber 5 respectively is a semiclosed cavity, establish a crossbeam 13 above in lock chamber 4, a left side, establish a crossbeam 13 above in right side lock is indoor, respectively establish a lock hole 10 in two crossbeams, 13 upright positions and corresponding position, locking bar 3 lower end, in lock chamber 4, a left side, dark screw 12 is respectively established with door bearing in right lock chamber 5, dark screw about in the of 12 symmetry establish two and get final product, make a left side, right two lock chambers form the sealing integral body of a closed shape, above crossbeam 13, constitute tapered end chamber 17, below two crossbeams 13, constitute lock body chamber 18, chamber 4 is locked on a left side, right lock chamber 5 is adopted long screw to pass dark screw 12 and is fixed on a left side, on the right door leaf, when door is closed, a left side, right two lock chambers 4,5 form the sealing integral body of a closo, make lock body and tapered end be in closed state, reach and to prize the purpose of pounding.Lock body is by a left side, upwards insert lock body chamber 18 lower ends of right lock chamber, two latch arm hole 9 are with left on the lock body, lock hole 10 on the right lock chamber is corresponding, again with two locking bars 3 on the tapered end 2 from a left side, tapered end chamber 17 upper ends of right lock chamber are inserted in the latch arm hole 9 in the lock body by lock hole 10 downwards, this moment, tapered end 2 dropped in the tapered end chamber 17, under the effect of crossbeam 13, tapered end is positioned at the crossbeam upper end, have in the lock body 1 and locking bar teeth groove 7 corresponding synchronous dead bolts 6, under the effect of elastic force, snap in automatically in the teeth groove of locking bar, form enclosed type locking state lock body.

When unblanking, key is inserted in cross lock core 8 holes, key makes synchronous dead bolt 6 withdraw from teeth groove 7, under the elastic force effect in lock body 1, by locking bar 3, tapered end 2 integral body is ejected from top, two lock chambers, takes out tapered end 2, finishes and unblanks.This crossbeam is equivalent to a nose to be used, and lock hole is equivalent to a nose buttonhole to be used.

Example 2, on the basis of said structure, tapered end 2 tops are designed to one oblique 11, as shown in Figure 4, make tapered end upper end become an anti-inclined-plane of pounding, tapered end integral body moves down and enters in the tapered end chamber that matches with tapered end with locking bar, and the teeth groove of locking bar is stuck by dead bolt again, can not on move, thereby make lockset integral body be in case type locking state.

Example 3, as Fig. 5, Fig. 6, shown in Figure 7, safety lock is a U-shape lock bar 14, tapered end 2 is removed, other structure is constant, at this moment lock chamber 4, a left side, right lock chamber 5 form the sealing integral body of a closed shape, the tapered end chamber 17 that crossbeam top constitutes is a U type cell body 15, on two crossbeams 13, respectively bore a lock hole 10 equally, when lock is locked, the two ends of U-shape lock bar 14 is passed lock hole 10 and is entered in the latch arm hole 9 in the lock body 1, and whole lock is fallen within the cavity of the closed shape that left and right lock chamber forms, and reaches anti-and turns round, pick-proof, anti-purpose of pounding.

Example 4, as Fig. 8, shown in Figure 9, in example 1, example 2, on the architecture basics of example 3, in lock chamber 4, a left side, the external vertical direction of right lock chamber 5 designs the chassis 16 of a sculpture, can design Cheng Long or other pattern on the chassis 16, the same two parts that divide, a part links together with lock chamber, a left side, a part connects together with right lock chamber, when door is closed, and lock chamber, a whole left side, right lock chamber lumps together together with two parts chassis 16, a left side, it is whole that right two lock chambers form a sealing, two parts chassis lumps together, promptly anti-turning round, pick-proof, anti-pounding, elegant in appearance again, and the outer impression and the intensity of increase lockset.
