Accompanying drawing explanation

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.

Fig. 1 is the structural representation of Novel safety lock.

In figure: pin plate 1, pin rod set 2, sell nose 3, nose plate 4, hole 5, cross bar 6, montant 7, the first positive stop 8, the second positive stop 9, on and off switch 10, alarm 11, accumulator 12, first binding post 13, the second binding post 14, contiguous block 15, spring 16, conductive contact blade 17, spacing catch 18.

Detailed description of the invention

As shown in Figure 1, a kind of Novel safety lock, include pin plate 1, it is located at the pin rod set 2 on pin plate 1, it is embedded and overlaps the pin rod in 2 at pin rod and carry out the pin nose 3 installed corresponding to pin plate 1, and pin nose includes nose plate 4 and hole 5, pin rod includes cross bar 6 and montant 7, overlap being positioned at pin rod 2 bottom-right pin plates 1 are additionally provided with the first positive stop 8, it is additionally provided with the second positive stop 9 being positioned on the pin plate 1 on the right side of the first positive stop 8, nose plate 4 is additionally provided with alarm mechanism, alarm mechanism includes on and off switch 10, alarm 11 and accumulator 12, in the vertical direction the first binding post 13 and the second binding post 14 spaced apart from each other is further respectively had being positioned on the nose plate 4 on the left of hole 5, and the first binding post passes through wire successively through on and off switch, alarm and accumulator are connected to the second binding post, it is additionally provided with contiguous block 15 being positioned on the nose plate 4 on the left of the first binding post 13 and the second binding post 14, right-hand member at contiguous block 15 is also associated with spring 16, right-hand member at spring 16 is also associated with conductive contact blade 17, and when the cross bar 6 of pin rod is not inserted in the hole 5 of pin nose 3, the two ends up and down of conductive contact blade 17 are in close contact the first binding post 13 and the second binding post 14 under the action of the spring 16 respectively, and when the cross bar 6 of pin rod is inserted in the hole 5 of pin nose 3, now the cross bar 6 of pin rod contacts and promotes conductive contact blade 17 direction to the left to move, and make the two ends up and down of conductive contact blade 17 be respectively further from the first binding post 13 and the second binding post 14.

By adopting said structure, when lockset is in off working state, on and off switch 10 is in open mode, so that alarm circuit is off, and when being intended to the locking operation performing pin rod, just pin rod direction to the left can be moved and is inserted in the hole 5 of the pin nose 3 corresponding with pin location, then the montant 7 of pin rod be rotated down so that the montant 7 of pin rod is embedded between pin rod set 2 and the first positive stop 8 and is close to the first positive stop 8; Meanwhile, the high order end of the cross bar 6 of pin rod has just contacted conductive contact blade 17 and has promoted conductive contact blade 17 direction to the left to move, the alarm circuit that the two ends up and down making conductive contact blade 17 are respectively further from the first binding post 13 and the second binding post 14(is now placed between the first binding post 13 and the second binding post 14 is just off), then on and off switch 10 is closed, now just complete the locking operation of lockset.When indoor people normally opens lockset, only need to first on and off switch 10 be reopened, then operation overturns pin rod and moves pin rod to the right, and when the people being positioned at outdoor is intended to mobile pin rod with abnormal condition or destroys pin rod, so once pin rod is moved to the right or is destroyed, pin rod just no longer contacts and props up conductive contact blade 17, now conductive contact blade 17 just moves under the action of the spring 16 to the right, and the two ends up and down of conductive contact blade 17 are in close contact the first binding post 13 and the second binding post 14 respectively, now alarm circuit is just in and closes conducting state completely, alarm 11 will be driven to work, report to the police, so that the people of indoor produces vigilance, so being greatly improved alarming anti-theft effect.

As preferably, for above-mentioned Novel safety lock, between contiguous block 15 and conductive contact blade 17, wherein it is also associated with horizontally extending expansion link (not shown), so, expansion link just plays the effect of guide rail between contiguous block 15 and conductive contact blade 17, make conductive contact blade 17 expansion link spacing under move left and right, more ensure that conductive contact blade 17 contacts conducting with the first binding post 13 and the stable of the second binding post 14.

As further preferably, for above-mentioned Novel safety lock, on the first positive stop 8, wherein it is additionally provided with spacing catch 18, and be hinged between spacing catch 18 and the first positive stop 8, so, after pin rod is completely disposed at latched position, can further rotary stopper catch 18, make spacing catch 18 cover the montant 7 of pin rod, only pin rod need to be rotated at random thus being entirely prevented from or avoiding and move pin rod along the axial direction of pin rod, so that it may latch is supported open easily.

As further preferred, for above-mentioned Novel safety lock, wherein the second positive stop 9 length vertically is more than the first positive stop 8 length vertically. Additionally, for above-mentioned Novel safety lock, alarm 11 therein is audible-visual annunciator.

As further preferred, for above-mentioned Novel safety lock, wherein it is also covered with insulating barrier at the outer surface of the cross bar 6 of pin rod, so, just more effectively avoid because the cross bar 6 of pin rod contacts by mistake with the first binding post 13 and the second binding post 14 simultaneously, and result in and the first binding post 13 and the second binding post 14 are connected, and then cause false alarm action.

In sum, by adopting said structure, this utility model simple in construction, reliable, security protection anti-theft effect can either be greatly promoted, it is also possible to report to the police in abnormal cases, thus significantly eliminating the potential safety hazard of room, family.

Above in conjunction with accompanying drawing, this utility model preferred embodiment and embodiment are explained in detail, but this utility model is not limited to the above-described embodiment and examples, in the ken that those skilled in the art possess, it is also possible to make various change without departing from the concept of the premise utility.
